Technical Field

The present invention relates to a cartridge (cartridge) having a winding core for winding an ink ribbon (ink ribbon) and a tape printer.

Background

Conventionally, as disclosed in patent document 1, a printing apparatus is known in which a first power transmission shaft and a second power transmission shaft having a double cylinder structure are provided so as to be rotatable independently of each other with respect to a central axis. The first torque is transmitted from the drive gear to the first power transmission shaft via the clutch spring, and the second torque smaller than the first torque is transmitted from the drive gear to the second power transmission shaft via the other clutch spring. When a cartridge for storing a wide ink ribbon is attached to a printing apparatus, a first power transmission shaft engages with a ribbon take-up spool (ribbon) and the ink ribbon is taken up on the ribbon take-up spool by a first torque. When the cartridge for storing the ink ribbon of a narrow width size is mounted on the printing apparatus, the second power transmission shaft engages with the ribbon take-up spool, and the ink ribbon is taken up on the ribbon take-up spool by the second torque.

Detailed Description

Hereinafter, an embodiment of the tape printing apparatus and the cartridge will be described with reference to the drawings. In the following drawings, an XYZ rectangular coordinate system is shown, but this is for convenience of explanation only and does not limit the following embodiments at all. The numerical values indicating the number of each part and the like are only examples, and do not limit the following embodiments at all.

Tape printing apparatus, tape cassette, and outline of ink ribbon cassette

As shown in fig. 1 to 3, the tape printing apparatus 1 includes a cartridge mounting section 2 to which a tape cartridge 101 and an ink ribbon cartridge 201 are mounted. Although not shown, the tape printing apparatus 1 includes an attachment cover that opens and closes the cartridge attachment unit 2.

As shown in fig. 1, the tape cassette 101 includes a tape core 102, a first platen roller 103, a first unwinding core 104, a first winding core 105, and a first cassette case 106. On the tape core 102, a first printing tape 107 is wound. The first printing tape 107 fed from the tape core 102 is fed out of the first cartridge case 106 from a tape feed-out port 108 provided in the peripheral wall portion on the-X side of the first cartridge case 106. On the first unwinding core 104, a first ink ribbon 109 is wound. The first ink ribbon 109 unwound from the first unwinding core 104 is wound on the first winding core 105. The first cartridge case 106 constitutes an outer case of the tape cartridge 101, and houses the tape core 102, the first platen roller 103, the first unwinding core 104, the first winding core 105, the first printing tape 107, and the first ink ribbon 109. The first cartridge case 106 is provided with a first head insertion hole 111 penetrating in the Z direction.

As shown in fig. 2, the ink ribbon cartridge 201 includes a second platen roller 203, a second unwinding core 204, a second winding core 205, and a second cartridge case 206. A second ink ribbon 209 is wound around the second unwinding core 204. The second ink ribbon 209 unreeled from the second unreeling core 204 is reeled on the second reeling core 205. The second cartridge case 206 constitutes an outer case of the ink ribbon cartridge 201, and houses the second platen roller 203, the second unwinding core 204, the second winding core 205, and the second ink ribbon 209. The second cartridge case 206 is provided with a second plug insertion hole 211 penetrating in the mounting direction. Further, in the second cartridge case 206, a second tape path 212 is provided. Although not shown, the second printing tape unwound from a tape reel provided outside the tape printing apparatus 1 is introduced into the second tape path 212.

The length of the second printing tape in the unused tape reel and the length of the second ink ribbon 209 stored in the unused tape cassette 201 are not particularly limited, but in the present embodiment, are longer than the length of the first printing tape 107 and the length of the first ink ribbon 109 stored in the unused tape cassette 101. Therefore, for example, in the case of manufacturing a large number of labels at a time, the ribbon cartridge 201 is mounted in the cartridge mounting section 2.

As shown in fig. 3 and 4, the cartridge mounting portion 2 is formed in a concave shape with the + Z side open. A head portion 4 and a core protrusion 5 are provided on a mounting bottom surface 3, which is a bottom surface of the cartridge mounting portion 2, i.e., a surface on the-Z side, so as to protrude toward the front side in the mounting direction. The head 4 includes a print head 6 and a head cap 7, and the head cap 7 covers at least the + X side, the-Y side, and the + Z side of the print head 6. The print head 6 is a thermal head provided with a heat generating element. When the tape cassette 101 is mounted in the cassette mounting section 2, the headcap 7 is inserted into the first head insertion through hole 111 to guide the mounting of the tape cassette 101. Further, when the ink ribbon cartridge 201 is mounted in the cartridge mounting section 2, the head cap 7 is inserted into the second head insertion through hole 211 to guide the mounting of the ink ribbon cartridge 201. The core protrusion 5 will be described later.

Further, on the mounting bottom surface 3, a platen shaft 8, a first wind-up shaft 11, a first wind-up shaft 9, a second wind-up shaft 12, and a second wind-up shaft 13 are provided in order from the-X side to the + Z side.

The platen shaft 8 is provided on the + Y side of the print head 6. The platen shaft 8 protrudes forward in the mounting direction by a larger amount than the first unwinding shaft 9, the first winding shaft 11, the second unwinding shaft 12, and the second winding shaft 13. When the tape cassette 101 is mounted in the cassette mounting section 2, the platen shaft 8 is inserted into the first platen roller 103 to guide the mounting of the tape cassette 101 together with the headcap 7. Further, when the ink ribbon cartridge 201 is mounted in the cartridge mounting section 2, the platen shaft 8 is inserted into the second platen roller 203 to guide the mounting of the ink ribbon cartridge 201 together with the headcap 7. Hereinafter, the mounting direction of the tape cassette 101 or the ink ribbon cassette 201 is simply referred to as a mounting direction. The mounting direction is parallel to the extending direction of the platen shaft 8, i.e., the Z direction. The near side in the mounting direction is the + Z side, and the deep side in the mounting direction is the-Z side.

The platen rotor 14 (see fig. 6), the first unwinding rotor 15, the first winding rotor 16, the second unwinding rotor 17, and the second winding rotor 18 are rotatably supported by the platen shaft 8, the first unwinding shaft 9, the first winding shaft 11, the second unwinding shaft 12, and the second winding shaft 13, respectively. When the tape cassette 101 is mounted in the cassette mounting portion 2, the first platen roller 103, the first unwinding core 104, and the first winding core 105 provided in the tape cassette 101 are engaged with the platen rotor 14, the first unwinding rotor 15, and the first winding rotor 16 provided in the cassette mounting portion 2, respectively. When the ink ribbon cartridge 201 is mounted in the cartridge mounting portion 2, the second platen roller 203, the second unwinding core 204, and the second winding core 205 provided in the ink ribbon cartridge 201 are engaged with the platen rotor 14, the second unwinding rotor 17, and the second winding rotor 18 provided in the cartridge mounting portion 2, respectively. The rotation of the feed motor 20 is transmitted to the platen rotor 14, the first unwinding rotor 15, the first winding rotor 16, the second unwinding rotor 17, and the second winding rotor 18 via a feed train 19.

Feed wheel train

As shown in fig. 5 to 7, the feed gear train 19 includes a motor-side gear train 21, a platen-side gear train 22, a ribbon-side gear train 23, a one-way clutch unit 24, an unwinding-side gear train 25, a first winding-side gear train 26, and a second winding-side gear train 27.

The motor side gear train 21 transmits the rotation of the feed motor 20 to the platen side gear train 22 and the ribbon side gear train 23. The platen-side gear train 22 transmits the rotation of the feed motor 20, which is input via the motor-side gear train 21, to the platen rotor 14. The ribbon-side gear train 23 transmits the rotation of the feed motor 20, which is input via the motor-side gear train 21, to the one-way clutch unit 24.

The one-way clutch unit 24 switches the transmission destination of the rotation of the feed motor 20, which is input via the ribbon side gear train 23, to the unwinding side gear train 25, the first winding side gear train 26, and the second winding side gear train 27, according to the rotation direction of the feed motor 20. That is, when the feed motor 20 rotates in the first direction, the one-way clutch unit 24 transmits the rotation of the feed motor 20, which is input through the ribbon side gear train 23, not to the unwinding side gear train 25 but to the first winding side gear train 26 and the second winding side gear train 27. Therefore, when the feeding motor 20 rotates in the first direction, the first unwinding rotor 15 and the second unwinding rotor 17 do not rotate, and the first winding rotor 16 and the second winding rotor 18 rotate. The first direction is a clockwise rotation direction in fig. 6 and 7. When the feed motor rotates in the first direction, the first winding rotor 16 and the second winding rotor 18 rotate in the direction opposite to the first direction, that is, counterclockwise.

On the other hand, when the feed motor 20 rotates in a second direction opposite to the first direction, the one-way clutch unit 24 transmits the rotation of the feed motor 20, which is input through the ribbon side gear train 23, to the unwinding side gear train 25, but not to the first winding side gear train 26 and the second winding side gear train 27. Therefore, when the feeding motor 20 rotates in the second direction, the first unwinding rotor 15 and the second unwinding rotor 17 rotate counterclockwise, and the first winding rotor 16 and the second winding rotor 18 do not rotate. Although not shown, the one-way clutch unit 24 includes two one-way clutches.

The unwinding side gear train 25 transmits the rotation of the feed motor 20, which is input through the one-way clutch unit 24, to the first unwinding rotor 15 and the second unwinding rotor 17.

The first winding-side gear train 26 transmits the rotation of the feed motor 20, which is input via the one-way clutch unit 24, to the first winding rotor 16. The first winding-side gear train 26 includes a first winding-side first gear 28 to which the rotation of the feed motor 20 is input via the one-way clutch unit 24, a first winding-side second gear 29 that meshes with the first winding-side first gear 28, and a first torque switching mechanism 31. The first torque switching mechanism 31 is a mechanism for switching the torque transmitted to the first winding rotor 16. The first torque switching mechanism 31 will be described later.

The second winding-side gear train 27 transmits the rotation of the feed motor 20, which is input via the one-way clutch unit 24, to the second winding rotor 18. The second winding-side gear train 27 includes a second winding-side first gear 32 to which the rotation of the feed motor 20 is input via the one-way clutch unit 24, a second winding-side second gear 33 that meshes with the second winding-side first gear 32, and a second torque switching mechanism 34 that is configured in the same manner as the first torque switching mechanism 31.

Printing process for mounting tape cassette

As shown in fig. 1, when the tape cassette 101 is mounted in the cassette mounting portion 2, the first platen roller 103, the first unwinding core 104, and the first winding core 105 provided in the tape cassette 101 are engaged with the platen rotor 14, the first unwinding rotor 15, and the first winding rotor 16 provided in the cassette mounting portion 2 shown in fig. 3, respectively. Thus, the rotation of the feed motor 20 can be transmitted to the first platen roller 103, the first unwinding core 104, and the first winding core 105.

Further, when the tape cassette 101 is mounted in the cassette mounting portion 2, the head portion 4 provided in the cassette mounting portion 2 is inserted in the first head insertion through hole 111 provided in the tape cassette 101. After the tape cassette 101 is mounted in the cassette mounting section 2, when the mounting section cover is closed, the print head 6 is moved toward the platen shaft 8 by the head moving mechanism 35 (see fig. 5). Thereby, the first printing tape 107 and the first ink ribbon 109 are sandwiched between the print head 6 and the first platen roller 103.

In this state, when the feed motor 20 rotates in the first direction, the rotation of the feed motor 20 is transmitted to the platen rotor 14 and the first winding rotor 16 via the feed gear train 19, the first platen roller 103 rotates in the feed direction, and the first winding core 105 rotates in the winding direction. Here, the feeding direction of the first platen roller 103 is a direction in which the first platen roller 103 rotates so that the first printing tape 107 is fed to the tape feed-out port 108. The winding direction of the first winding core 105 is a direction in which the first winding core 105 rotates so that the first ink ribbon 109 unwound from the first unwinding core 104 is wound around the first winding core 105. In other words, in fig. 1, the feeding direction of the first platen roller 103 is a clockwise rotation direction, and the winding direction of the first winding core 105 is a counterclockwise rotation direction.

When the feed motor 20 rotates in the second direction, the rotation of the feed motor 20 is transmitted to the platen rotor 14 and the first unwinding rotor 15 via the feed gear train 19, the first platen roller 103 rotates in the retracting direction, and the first unwinding core 104 rotates in the unwinding direction. Here, the pull-back direction of the first platen roller 103 is a direction in which the first platen roller 103 rotates so that the first printing tape 107 fed to the tape feed-out port 108 is pulled back. The winding direction of the first unwinding core 104 is a direction in which the first unwinding core 104 rotates so that the first ink ribbon 109 unwound from the first unwinding core 104 is wound around the first unwinding core 104. In other words, in fig. 1, both the pull-back direction of the first platen roller 103 and the rewind direction of the first unwinding core 104 are counterclockwise.

The tape printing apparatus 1 rotates the feed motor 20 in the first direction and causes the print head 6 to generate heat, thereby printing the first printing tape 107 and the first ink ribbon 109 and printing the first printing tape 107 with print information input from a keyboard and the like, which are not shown. After the printing is completed, although not shown, the tape printing apparatus 1 cuts the printed portion of the first printing tape 107 by performing a cutting operation on a cutter provided between the cartridge mounting portion 2 and the tape discharge port. Thereafter, the tape printing apparatus 1 rotates the feed motor 20 in the second direction to pull back the first printing tape 107 until the tip end of the first printing tape 107 comes near the nip position between the print head 6 and the first platen roller 103. This can shorten the margin generated at the front side in the longitudinal direction of the first printing belt 107 to be printed next.

In addition, the tape printing apparatus 1 performs the printing process in the same manner when the ink ribbon cartridge 201 is mounted in the cartridge mounting section 2. That is, the tape printing apparatus 1 prints on the second printing tape while feeding the second printing tape and the second ink ribbon 209 sandwiched between the print head 6 and the second platen roller 203.

Tape box

A first tape cassette 101a and a second tape cassette 101b are prepared for the tape cassette 101, and as shown in fig. 8, the first tape cassette 101a is a tape cassette in which a first printing tape 107 and a first ink ribbon 109 each having a wide width, for example, a width of 50mm are accommodated, and as shown in fig. 9, the second tape cassette 101b is a tape cassette in which a first printing tape 107 and a first ink ribbon 109 each having a narrow width, for example, a width of 36mm are accommodated. In fig. 9, the first printing tape 107 and the first ink ribbon 109 are not shown. Hereinafter, the first tape cassette 101a and the second tape cassette 101b will be referred to as the tape cassette 101 only when there is no need to distinguish them. The first tape cassette 101a and the second tape cassette 101b are configured substantially similarly, and a common configuration will be described with reference to the drawings of the first tape cassette 101a as a representative example.

As shown in fig. 10, the tape cassette 101 includes a near-front-side core support shaft 112, and the near-front-side core support shaft 112 protrudes in a substantially cylindrical shape from an inner surface of a wall portion on the near side in the mounting direction of the first cassette case 106 to the depth side in the mounting direction. The tape cassette 101 includes a depth core support shaft 113, and the depth core support shaft 113 protrudes from the inner surface of the wall portion on the mounting direction depth side of the first cassette case 106 toward the front side in the mounting direction to form a substantially stepped cylindrical shape. The proximal core support shaft 112 and the deep core support shaft 113 are provided so as to face each other in the Z direction. The proximal core support shaft 112 and the deep core support shaft 113 rotatably support the core 102.

An anti-reverse spring 114 is provided inside the proximal core support shaft 112 and the deep core support shaft 113. The anti-reverse spring 114 is formed of, for example, a compression coil spring, and prevents the core 102 from rotating in the reverse direction when the tape cassette 101 is not mounted in the cassette mounting portion 2 by engaging the end portion on the mounting direction deep side with the core 102. When the tape cassette 101 is mounted in the cassette mounting portion 2, a core protrusion 5 provided in the cassette mounting portion 2 is inserted into a core recess 115, which will be described later, provided inside a deep core support shaft 113 provided in the tape cassette 101. Thereby, the anti-reverse spring 114 provided inside the near-front core support shaft 112 and the deep-side core support shaft 113 is compressed, and the anti-reverse spring 114 and the belt core 102 are disengaged from each other, so that the belt core 102 can freely rotate.

As shown in fig. 11, a core recess 115 is provided on the outer surface of the wall portion on the mounting direction deep side of the first cartridge case 106 so as to be recessed toward the front side in the mounting direction. The core recess 115 is formed by an internal space of the deep core support shaft 113. The core recess 115 includes a base recess 116 on the mounting direction deep side and an insertion recess 117 on the mounting direction near side. The base recess 116 is recessed in a substantially circular shape from the outer surface of the wall portion on the mounting direction deep side of the first cartridge case 106. The insertion recess 117 is recessed from the bottom surface of the base recess 116 in a substantially circular shape having a smaller diameter than the base recess 116. An annular convex portion 118 protruding from the inner peripheral surface of the insertion concave portion 117 toward the depth in the mounting direction is provided in the base concave portion 116.

Here, in the first tape cassette 101a and the second tape cassette 101b, the structure inside the base concave portion 116 is different. That is, in the second tape cassette 101b, as shown in fig. 12, a connecting convex portion 119 on the-X side, a connecting concave portion 121 on the + X side, a first connecting portion (not shown) on the-Y side, and a second connecting portion 123 on the + Y side are provided so as to connect the outer peripheral surface of the annular convex portion 118 and the inner peripheral surface of the base concave portion 116. The connection convex portion 119, the connection concave portion 121, the first connection portion, and the second connection portion 123 are provided at substantially equal intervals in the circumferential direction of the base concave portion 116. The arrangement of the connection convex portion 119, the connection concave portion 121, the first connection portion, and the second connection portion 123 is not limited to the above-described configuration. For example, the connection convex portion 119 may be set to the-Y side, the connection concave portion 121 may be set to the + Y side, the first connection portion may be set to the + X side, and the second connection portion 123 may be set to the-X side. By changing the arrangement of the coupling convex portion 119, the coupling concave portion 121, the first coupling portion, and the second coupling portion 123, the tape cassette can be used for identification or the like when the specifications of the first printing tape 107 are different, for example, depending on the country or region where the second tape cassette 101b is sold.

In contrast, as shown in fig. 13, in the first tape cassette 101a, the four cassette-side engaging portions 124 are located on the attachment-direction deep side of the coupling convex portion 119, the coupling concave portion 121, the first coupling portion, and the second coupling portion 123, and are provided so as to protrude from the inner peripheral surface of the base concave portion 116. That is, the first tape cassette 101a and the second tape cassette 101b differ in the presence or absence of the four cassette-side engagement portions 124. Since the cartridge-side engagement portion 124 is provided on the inner peripheral surface of the base concave portion 116, the cartridge-side engagement portion 124 can be prevented from being damaged even when the first tape cartridge 101a falls.

The four cartridge-side engaging portions 124 are provided at substantially equal intervals in the circumferential direction of the base recessed portion 116. The cartridge-side engaging portion 124 extends from the vicinity of the opening of the base concave portion 116 toward the bottom surface of the base concave portion 116 toward the front side in the mounting direction. Of the four cartridge-side engaging portions 124, the cartridge-side engaging portion 124 on the-X side is referred to as a cartridge-side first engaging portion 124a, the cartridge-side engaging portion 124 on the + X side is referred to as a cartridge-side second engaging portion 124b, the cartridge-side engaging portion 124 on the-Y side is referred to as a cartridge-side third engaging portion 124c, and the cartridge-side engaging portion 124 on the + Y side is referred to as a cartridge-side fourth engaging portion 124 d. When it is not necessary to distinguish between these cartridge-side engaging portions, these portions are simply referred to as cartridge-side engaging portions 124. As shown in fig. 11, the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b are provided at positions point-symmetrical to each other with respect to the center of the core concave portion 115 when viewed from the mounting direction depth side. Similarly, the cartridge-side third engaging portion 124c and the cartridge-side fourth engaging portion 124d are provided at positions point-symmetrical to each other with respect to the center of the core recess 115 when viewed from the mounting-direction depth side. The cartridge-side first engaging portion 124a is provided corresponding to a device-side first engaging portion 49a (see fig. 15) described later, and the cartridge-side second engaging portion 124b is provided corresponding to a device-side second engaging portion 49b (see fig. 15) described later.

Core convex part

As shown in fig. 3, 4, and 14, the core convex portion 5 is formed in a substantially stepped cylindrical shape as a whole, and includes a base convex portion 36 on the mounting direction deep side and an insertion convex portion 37 on the mounting direction near side. The base projection 36 protrudes from the bottom surface of the cartridge mounting portion 2 in a substantially cylindrical shape. The insertion projection 37 projects from the distal end surface of the base projection 36 into a substantially cylindrical shape having a smaller diameter than the base projection 36.

The base convex portion 36 is provided with four base opening portions 38. Each base opening 38 is formed by cutting out a corner portion of the distal end surface and the peripheral surface of the base projection 36. The four base openings 38 are provided at substantially equal intervals in the circumferential direction of the base protrusion 36. Hereinafter, among the four base openings 38, the base opening 38 on the-X side is referred to as a first base opening 38a, the base opening 38 on the + X side is referred to as a second base opening 38b, the base opening 38 on the-Y side is referred to as a third base opening 38c, and the base opening 38 on the + Y side is referred to as a fourth base opening 38 d. When it is not necessary to distinguish between these base openings, they are simply referred to as base openings 38. As shown in fig. 3, the first base opening 38a and the second base opening 38b are provided at positions point-symmetrical to each other with respect to the center of the core protrusion 5 when viewed from the front side in the mounting direction. Similarly, the third base opening 38c and the fourth base opening 38d are provided at positions point-symmetrical to each other with respect to the center of the core protrusion 5 when viewed from the front side in the mounting direction.

As shown in fig. 15 and 16, when the tape cassette 101 is mounted in the cassette mounting portion 2, the core protrusion 5 provided in the cassette mounting portion 2 is inserted from the mounting direction deep side with respect to the core recess 115 provided in the tape cassette 101. That is, the base convex portion 36 is inserted into the base concave portion 116, and the insertion convex portion 37 is inserted into the insertion concave portion 117.

Here, as shown in fig. 15, when the first tape cassette 101a is mounted in the cassette mounting section 2, the cassette-side engagement portion 124 provided on the inner peripheral surface of the base concave portion 116 enters the base convex portion 36 via the base opening portion 38. Thus, the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b of the four cartridge side engaging portions 124 are engaged with the device side first engaging portion 49a and the device side second engaging portion 49b, respectively, which will be described later. As shown in fig. 14, when the first tape cassette 101a is detached from the cassette mounting portion 2, the cassette-side engagement portion 124 protrudes out of the base projection 36 through the base opening 38. Thereby, the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b are disengaged from the device side first engaging portion 49a and the device side second engaging portion 49b, respectively.

On the other hand, as shown in fig. 16, when the second tape cartridge 101b having no cartridge-side engaging portion 124 is mounted on the cartridge mounting section 2, the base concave portion 116 does not engage with the device-side first engaging portion 49a and the device-side second engaging portion 49 b.

First torque switching mechanism

The first torque switching mechanism 31 is configured to switch the torque transmitted to the first take-up rotor 16 from the second torque to the first torque larger than the second torque when the first tape cassette 101a is mounted in the cassette mounting portion 2. That is, when the first tape cartridge 101a in which the first ink ribbon 109 having a wide width is stored is mounted in the cartridge mounting section 2, the torque transmitted to the first take-up rotor 16 is switched to the first torque larger than the second torque by the first torque switching mechanism 31. Therefore, the wide first ink ribbon 109 sandwiched between the print head 6 and the first platen roller 103 together with the first printing tape 107 can be appropriately peeled off from the first printing tape 107 and wound. On the other hand, when the second tape cassette 101b accommodating the first ink ribbon 109 having a narrow width is mounted, the first torque switching mechanism 31 does not perform torque switching from a state in which the tape cassette 101 is not mounted, and the torque transmitted to the first take-up rotor 16 becomes the second torque smaller than the first torque. Therefore, the first ink ribbon 109 having a narrow width can be prevented from being damaged.

As shown in fig. 17 and 18, the first torque switching mechanism 31 includes a first winding gear 41, a second winding gear 42, a first slide spring 43, and a second slide spring 44. The first torque switching mechanism 31 includes a movable gear 46, two switching actuators 47, and a gear support portion 48 (see fig. 19 and 20), which will be described later.

The first winding gear 41 is rotatably supported on the first winding shaft 11. That is, the first winding gear 41 is located on the installation direction deep side of the first winding rotor 16, and is provided on the same shaft as the first winding rotor 16. The first winding gear 41 is coupled to the first winding rotor 16 via a first slide spring 43, and rotates the first winding rotor 16.

The second winding gear 42 is rotatably supported on the first winding shaft 11. That is, the second winding gear 42 is located on the installation direction depth side of the first winding gear 41 and is provided on the same shaft as the first winding rotor 16. The second winding gear 42 is coupled to the first winding gear 41 via a second slide spring 44, and rotates the first winding rotor 16 via the first winding gear 41.

The first slide spring 43 is disposed between the first winding gear 41 and the first winding rotor 16. The first slip spring 43 limits the torque transmitted from the first winding gear 41 to the first winding rotor 16 to a first torque. The second slide spring 44 is disposed between the second winding gear 42 and the first winding gear 41. The second slip spring 44 limits the torque transmitted from the second take-up gear 42 to the first take-up gear 41 to a second torque smaller than the first torque. Further, the torque transmitted from the second winding gear 42 to the first winding gear 41 does not exceed the first torque, and therefore, is further transmitted to the first winding rotor 16 via the first slide spring 43. In addition, the first slide spring 43 is an example of a "first torque limiter". The second slide spring 44 is one example of a "second torque limiter".

The movable gear 46 is engaged with or disengaged from the first winding gear 41, and the first winding-side second gear 29 is always engaged with the second winding gear 42. Therefore, when the movable gear 46 is engaged with the first winding gear 41 and the rotation of the feed motor 20 is input to the first winding gear 41 via the movable gear 46, the torque transmitted to the first winding rotor 16 is limited to the first torque by the first slide spring 43. On the other hand, when the movable gear 46 is disengaged from the first winding gear 41 and the rotation of the feed motor 20 is input to the first winding gear 41 via the second winding gear 42, the torque transmitted to the first winding rotor 16 is limited to the second torque by the second slide spring 44.

As shown in fig. 19 and 20, the movable gear 46 is rotatably supported by the gear support portion 48 and is configured to be engageable with and disengageable from the first winding gear 41. The movable gear 46 is constantly meshed with the first winding-side first gear 28 (see fig. 6 and 7).

Each switching actuator 47 is provided with a device-side engaging portion 49, and the device-side engaging portion 49 engages with the cartridge-side engaging portion 124 when the first tape cartridge 101a is mounted in the cartridge mounting section 2. Here, the device-side engaging portion 49 on the-X side of the two device-side engaging portions 49 is referred to as a device-side first engaging portion 49a, and the device-side engaging portion 49 on the + X side is referred to as a device-side second engaging portion 49 b. When the device-side first engaging portion 49a and the device-side second engaging portion 49b do not need to be distinguished, they are simply referred to as the device-side engaging portions 49. Of the two switching actuators 47, the switching actuator 47 provided with the device-side first engagement portion 49a is referred to as a first switching actuator 47a, and the switching actuator 47 provided with the device-side second engagement portion 49b is referred to as a second switching actuator 47 b. In the case where there is no need to distinguish between the first and second switching actuators 47a, 47b, it is referred to only as the switching actuator 47.

The first switching actuator 47a is rotatably provided on an actuator shaft, not shown. The first switching actuator 47a is formed in a substantially L shape when viewed from the front side in the mounting direction. A first actuator-side shaft insertion portion 51 through which a first actuator shaft (not shown) is inserted is provided at the + Y-side end portion of the first switching actuator 47 a. A first actuator-side engaging portion 52 that protrudes to the depth side in the mounting direction is provided at the end portion on the + X side of the first switching actuator 47 a. The first actuator-side engaging portion 52 engages with a support-side first engaging portion 67 described later. The device-side first engaging portion 49a is located on the-X side and the-Y side of the first actuator-side shaft insertion portion 51, and projects toward the front side in the mounting direction. The device-side first engaging portion 49a is provided with a first engaging inclined surface 54 inclined so that the mounting direction depth side is referred to as the-X side, and a first working surface 55 extending from an end portion of the first engaging inclined surface 54 on the mounting direction depth side toward the mounting direction depth side.

The first switching actuator 47a is biased in a clockwise direction by an actuator spring 56 (see fig. 6). One end of the actuator spring 56 is engaged with a support shaft (not shown) of the first winding-side second gear 29, and the other end is engaged with the + X-side end of the first switching actuator 47 a. As the actuator spring 56, for example, a torsion coil spring can be used. The clockwise direction is a clockwise direction when viewed from the front side in the mounting direction. Likewise, counterclockwise means counterclockwise when viewed from the front side in the mounting direction.

The second switching actuator 47b is rotatably provided on a second actuator shaft (not shown). The second switching actuator 47b is formed in a substantially triangular shape when viewed from the front side in the mounting direction. At the-Y side end portion of the second switching actuator 47b, a second actuator-side shaft insertion portion 57 through which the second actuator shaft is inserted is provided. The second switching actuator 47b is provided with a second actuator-side engaging portion 58, and the second actuator-side engaging portion 58 is located on the + X side and the + Y side of the second actuator-side shaft insertion portion 57 and protrudes to the depth side in the mounting direction. The second actuator-side engaging portion 58 engages with a support-side second engaging portion 69 described later. The device-side second engaging portion 49b is located on the-X side and the + Y side of the second actuator-side shaft insertion portion 57 and projects forward in the mounting direction. The apparatus-side second engaging portion 49b is provided with a second engaging inclined surface 61 inclined so that the mounting direction depth side becomes the + X side, and a second working surface 62 extending from the end portion of the second engaging inclined surface 61 on the mounting direction depth side toward the mounting direction depth side. In addition, instead of the first engagement inclined surface 54 and the second engagement inclined surface 61, the cartridge side first engagement portion 124a and the cartridge side second engagement portion 124b may be provided with inclined surfaces.

As shown in fig. 14, the device-side first engaging portion 49a and the device-side second engaging portion 49b are provided inside the base convex portion 36. That is, the device-side first engaging portion 49a and the device-side second engaging portion 49b are provided on the mounting-direction deep side with respect to the first base opening 38a and the second base opening 38b, respectively. The device-side first engaging portion 49a and the device-side second engaging portion 49b are provided corresponding to the cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b, respectively. The apparatus side first engaging portion 49a and the apparatus side second engaging portion 49b are engaged with the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b substantially simultaneously when the first tape cartridge 101a is mounted in the cartridge mounting portion 2. The first device-side engaging portion 49a and the second device-side engaging portion 49b are provided at positions that are point-symmetrical with respect to the center of the core protrusion 5 when viewed from the front side in the mounting direction (see fig. 3).

As shown in fig. 6, 7, 19, and 20, the gear support portion 48 is configured to be rotatable so as to separate or connect the movable gear 46 rotatably supported from or to the first winding gear 41. The gear support portion 48 includes a first actuator-side support member 63, a second actuator-side support member 64, and a support spring 65.

The first actuator side support member 63 is rotatably provided on the clutch shaft 45 (see fig. 5), and the clutch shaft 45 is provided on substantially the same shaft as the second actuator shaft. A support-portion-side first shaft insertion portion 66, through which the clutch shaft 45 is inserted, is provided in a substantially cylindrical shape at the + Y-side end portion of the first actuator-side support member 63. At the-Y-side end portion of the first actuator-side support member 63, the movable gear 46 is rotatably supported. A support portion side first engagement portion 67 is provided at a substantially intermediate portion of the first actuator side support member 63. The support-portion-side first engaging portion 67 engages with the first actuator-side engaging portion 52.

The second actuator side support member 64 is rotatably provided on the clutch shaft 45, and a support portion side second insertion portion 68 through which the clutch shaft 45 is inserted is provided in a substantially short cylindrical shape at a substantially intermediate portion of the second actuator side support member 64. The support portion-side first shaft insertion portion 66 is inserted into the support portion-side second shaft insertion portion 68 from the attachment direction deep side. A support-portion-side second engagement portion 69 is provided at the + Y-side end portion of the second actuator-side support member 64. The support-unit-side second engagement portion 69 engages with the second actuator-side engagement portion 58.

The support spring 65 elastically connects the first actuator side support member 63 and the second actuator side support member 64. The support spring 65 is provided on the clutch shaft 45, and has one end thereof engaged with the first actuator side support member 63 and the other end thereof engaged with the second actuator side support member 64. The support spring 65 biases the second actuator side support member 64 to rotate clockwise when the first actuator side support member 63 is fixed. As the support spring 65, for example, a torsion coil spring can be used. The support spring 65 is an example of an "elastic member".

Change of state of the first torque switching mechanism

When the first tape cassette 101a is mounted in the cassette mounting section 2, as described above, the first cassette-side engagement portion 124a and the second cassette-side engagement portion 124b engage with the first device-side engagement portion 49a and the second device-side engagement portion 49b, respectively (see fig. 15).

At this time, the cartridge-side first engaging portion 124a engages with the apparatus-side first engaging portion 49a in the order of the first inclined engaging surface 54 and the first operating surface 55. Thereby, the device side first engaging portion 49a is pressed toward the + X side. As a result, as shown in fig. 21, the first switching actuator 47a rotates counterclockwise from the state shown in fig. 22 against the elastic force of the actuator spring 56. At this time, since the first actuator-side engaging portion 52 of the first switching actuator 47a moves to the + X side, the support-side first engaging portion 67 that engages with the first actuator-side engaging portion 52 on the-X side of the first actuator-side engaging portion 52 can move to the + X side. Thereby, the first actuator-side support member 63 can be rotated counterclockwise, that is, in a direction in which the movable gear 46 supported by the first actuator-side support member 63 approaches the first take-up gear 41. Thus, when the cartridge-side first engaging portion 124a engages with the device-side first engaging portion 49a, the first switching actuator 47a rotates counterclockwise, thereby allowing the first actuator-side support member 63 to rotate counterclockwise.

The cartridge-side second engaging portion 124b engages with the apparatus-side second engaging portion 49b in the order of the second inclined engaging surface 61 and the second operating surface 62. Thereby, the device side second engaging portion 49b is pressed toward the-X side. As a result, as shown in fig. 21, the second switching actuator 47b rotates counterclockwise from the state shown in fig. 22. At this time, the second actuator side engagement portion 58 of the second switching actuator 47b presses the support portion side second engagement portion 69 of the second actuator side support member 64 toward the-X side, so that the second actuator side support member 64 rotates counterclockwise. When the second actuator-side support member 64 rotates counterclockwise, the first actuator-side support member 63 elastically connected to the second actuator-side support member 64 via the support spring 65 rotates counterclockwise, that is, in a direction in which the movable gear 46 supported by the first actuator-side support member 63 approaches the first take-up gear 41. As a result, as shown in fig. 6, the movable gear 46 meshes with the first take-up gear 41. When the cartridge-side second engagement portion 124b is engaged with the apparatus-side second engagement portion 49b, the second switching actuator 47b rotates counterclockwise, and the first actuator-side support member 63 rotates counterclockwise.

Here, the first actuator-side support member 63 and the second actuator-side support member 64 are elastically connected by a support spring 65. Therefore, the second actuator-side support member 64 is rotated counterclockwise by the meshing rotation amount θ from the state shown in fig. 22, and after the movable gear 46 meshes with the first take-up gear 41, it is also rotated counterclockwise by the additional rotation amount α with respect to the first actuator-side support member 63 against the elastic force of the support spring 65. Here, the engagement rotation amount θ is the minimum value of the rotation amount of the second actuator side support member 64 required for the movable gear 46 to engage with the first take-up gear 41. Therefore, if the rotation amount of the second actuator side support member 64 is equal to or greater than the meshing rotation amount θ and equal to or less than the sum (θ + α) of the meshing rotation amount θ and the additional rotation amount α, the movable gear 46 is pressed against the first take-up gear 41 with an appropriate load. Therefore, the design value of the rotation amount of the second actuator side support member 64 may be set to a value greater than θ and smaller than (θ + α). Thus, even if the amount of rotation of the second actuator-side support member 64 varies due to dimensional variations in the cartridge-side second engagement portion 124b and the like, the movable gear 46 can be appropriately meshed with the first take-up gear 41 as long as the value is equal to or greater than θ (θ + α) or less. That is, the support spring 65 can absorb dimensional variations of the cartridge-side second engaging portion 124b and the like.

In this way, when the first tape cassette 101a is mounted on the cassette mounting section 2, the cassette side first engaging portion 124a and the cassette side second engaging portion 124b engage with the device side first engaging portion 49a and the device side second engaging portion 49b, respectively. Thereby, the gear support portion 48 rotates counterclockwise, and the movable gear 46 meshes with the first take-up gear 41. As a result, the first torque switching mechanism 31 changes the state to a first state in which the rotation of the feed motor 20 is input to the first take-up gear 41 via the movable gear 46, that is, the torque to be transmitted to the first take-up rotor 16 is the first torque.

Next, a change in state of the first torque switching mechanism 31 when the first tape cassette 101a is detached will be described. When the first tape cassette 101a is detached from the cassette mounting portion 2, as described above, the cassette-side first engaging portion 124a and the cassette-side second engaging portion 124b are disengaged from the device-side first engaging portion 49a and the device-side second engaging portion 49b, respectively.

When the engagement between the cartridge-side first engaging portion 124a and the device-side first engaging portion 49a is released, the first switch actuator 47a is rotated clockwise by the elastic force of the actuator spring 56 as shown in fig. 22 from the state shown in fig. 21. Thereby, the first actuator-side engaging portion 52 of the first switching actuator 47a presses the support-portion-side first engaging portion 67 of the first actuator-side support member 63 toward the-X side. Therefore, the first actuator-side support member 63 rotates clockwise, that is, in a direction in which the movable gear 46 supported by the first actuator-side support member 63 is separated from the first take-up gear 41. As a result, as shown in fig. 7, the movable gear 46 is disengaged from the first take-up gear 41. When the cartridge-side first engaging portion 124a is disengaged from the device-side first engaging portion 49a, the first switching actuator 47a rotates clockwise, and the first actuator-side support member 63 is rotated clockwise, thereby preventing the first actuator-side support member 63 from rotating counterclockwise.

When the first actuator side support member 63 rotates clockwise, the second actuator side support member 64 elastically connected to the first actuator side support member 63 via the support spring 65 rotates clockwise. Thereby, the support portion side second engagement portion 69 of the second actuator side support member 64 presses the second actuator side engagement portion 58 of the second switching actuator 47b to the + X side. At this time, as described above, the engagement between the cartridge-side second engagement portion 124b and the apparatus-side second engagement portion 49b is disengaged, so that the apparatus-side second engagement portion 49b can move to the + X side, that is, the second switching actuator 47b can rotate clockwise. Therefore, the second switching actuator 47b is pressed against the second actuator side support member 64 and rotates clockwise.

In this way, when the first tape cassette 101a is detached from the cassette mounting section 2, the cassette side first engagement portion 124a and the cassette side second engagement portion 124b are disengaged from the device side first engagement portion 49a and the device side second engagement portion 49b, respectively. Thereby, the gear support portion 48 rotates clockwise, and the movable gear 46 is disengaged from the first winding gear 41. As a result, the first torque switching mechanism 31 changes the state to a second state in which the rotation of the feed motor 20 is input to the first winding gear 41 via the second winding gear 42, that is, the torque to be transmitted to the first winding rotor 16 is set to the second torque.

As described above, when the second tape cartridge 101b is mounted in the cartridge mounting section 2, the coupling convex portion 119 and the coupling concave portion 121 are not engaged with the apparatus-side first engaging portion 49a and the apparatus-side second engaging portion 49b, respectively (see fig. 16). Therefore, when the second tape cassette 101b is mounted in the cassette mounting section 2, the first torque switching mechanism 31 maintains the second state, and the torque transmitted to the first winding rotor 16 maintains the second torque.

As described above, according to the first tape cassette 101a and the tape printing apparatus 1 of the present embodiment, when the first tape cassette 101a is mounted in the cassette mounting portion 2, the first torque switching mechanism 31 changes the state from the second state to the first state by the engagement of the first cartridge-side engagement portion 124a and the second cartridge-side engagement portion 124b with the first device-side engagement portion 49a and the second device-side engagement portion 49b, respectively. Thereby, the torque transmitted to the first winding rotor 16 is switched from the second torque to the first torque. Therefore, the diameter of the first winding core 105 can be reduced and the first tape cassette 101a can be downsized compared to the case where the first winding rotor 16 has a double-cylinder structure. Further, the amount of looseness of the first winding rotor 16 with respect to the first winding shaft 11 is smaller than in the case where the first winding rotor 16 has a double-drum structure. Therefore, the center of the first winding core 105 and the center of the first winding shaft 11 can be made substantially coincident with each other, and therefore the first ink ribbon 109 can be appropriately wound around the first winding core 105.

Further, according to the first tape cassette 101a and the tape printing apparatus 1 of the present embodiment, the first tape cassette 101a and the first torque switching mechanism 31 are engaged not only at one place, but at two places, that is, the first cartridge-side engagement portion 124a and the first apparatus-side engagement portion 49a, and the second cartridge-side engagement portion 124b and the second apparatus-side engagement portion 49 b. Therefore, the load due to the engagement acts on the first tape cassette 101a in a balanced manner, and the first tape cassette 101a is prevented from being inclined with respect to the cassette mounting portion 2, so that the running performance of the first printing tape 107 and the first ink ribbon 109 can be improved.

As in the present embodiment, the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b are not limited to a configuration in which they are arranged point-symmetrically with respect to the center of the core concave portion 115, and may be engaged with the apparatus side first engaging portion 49a and the apparatus side second engaging portion 49b, respectively. For example, the size between the cartridge side first engaging portion 124a and the center of the core recess 115 and the size between the cartridge side second engaging portion 124b and the center of the core recess 115 may be different. Further, the cartridge side first engaging portion 124a, the center of the core recess 115, and the cartridge side second engaging portion 124b may not be arranged on a straight line when viewed from the mounting direction depth side. That is, the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b may be disposed to face each other with the center of the core concave portion 115 interposed therebetween, as long as they are within a range in which they can engage with the apparatus side first engaging portion 49a and the apparatus side second engaging portion 49 b. Further, the shape of the cartridge-side first engaging portion 124a and the shape of the cartridge-side second engaging portion 124b, which are disposed to face each other with the center of the core recess 115 interposed therebetween, may be different from each other when viewed from the mounting direction depth side. Similarly, the device-side first engaging portion 49a and the device-side second engaging portion 49b are not limited to a configuration in which they are disposed in point symmetry with respect to the center of the core protrusion 5. Preferably, the direction in which the device side first engaging portion 49a is pressed by the cartridge side first engaging portion 124a and the direction in which the device side second engaging portion 49b is pressed by the cartridge side second engaging portion 124b are opposite to each other.

Other modifications

Of course, the present invention is not limited to the above-described embodiments, and various configurations can be adopted without departing from the scope of the present invention. For example, the above embodiment can be modified as follows in addition to the above.

The cartridge-side engaging portion 124 is not limited to the structure formed on the inner peripheral surface of the base concave portion 116, and may be provided at any position of the tape cartridge 101 as long as it can engage with the apparatus-side engaging portion 49. For example, as shown in fig. 23, the cartridge side first engaging portion 124a and the cartridge side second engaging portion 124b may be provided at the edge portion of the core recessed portion 115, and may be configured to partially overlap the core recessed portion 115 when viewed from the mounting direction depth side. That is, the cartridge-side engaging portion 124 may be provided on the outer surface of the first cartridge case 106 on the mounting-direction deep side. The cartridge-side first engaging portion 124a and the cartridge-side second engaging portion 124b shown in fig. 23 are substantially rectangular plate-shaped, but the shape is not particularly limited, and may be, for example, an oblong plate-shaped, a hemispherical shape, or the like. The cartridge-side engaging portion 124 may protrude from the bottom surface of the base concave portion 116 to the depth side in the mounting direction. At this time, the cartridge-side engaging portion 124 may or may not be formed integrally with the inner peripheral surface of the base concave portion 116.

The first torque switching mechanism 31 is not limited to a configuration in which the state is changed from the second state to the first state when the tape cassette 101 is attached, and may be a configuration in which the state is changed from the first state to the second state when the tape cassette 101 is attached, the first state being a state in which the torque transmitted to the first winding rotor 16 is set to the first torque which is large, and the second state being a state in which the torque transmitted to the first winding rotor 16 is set to the second torque which is small.

In this configuration, for example, the cartridge-side engaging portion 124 is provided in the second tape cartridge 101b, but not in the first tape cartridge 101 a. The first torque switching mechanism 31 further includes a lock portion that locks the movable gear 46 in a state of meshing with the first winding gear 41. When the second tape cartridge 101b is mounted in the cartridge mounting section 2, the cartridge-side engaging portion 124 engages with the apparatus-side engaging portion 49, so that the locking of the locking portion is released, and the movable gear 46 is released from the first take-up gear 41. When the second tape cassette 101b is detached from the cassette mounting portion 2, the movable gear 46 is locked by the locking portion in a state of being meshed with the first take-up gear 41. Thereby, the first torque switching mechanism 31 changes the state from the first state to the second state when the second tape cassette 101b is mounted in the cassette mounting section 2. Further, the first torque switching mechanism 31 changes the state from the second state to the first state when the second tape cassette 101b is detached from the cassette mounting portion 2. On the other hand, the first torque switching mechanism 31 is also in the first state when the first tape cartridge 101a is mounted on the cartridge mounting section 2.

The tape printing apparatus 1 may be configured such that one of the first switching actuator 47a and the second switching actuator 47b includes an apparatus-side third engaging portion provided on the mounting-direction depth side of the third base opening 38c, and the other of the first switching actuator 47a and the second switching actuator 47b includes an apparatus-side fourth engaging portion provided on the mounting-direction depth side of the fourth base opening 38 d. That is, the tape printing apparatus 1 may be configured to include, as the apparatus-side engaging portion 49, an apparatus-side third engaging portion provided corresponding to the cartridge-side third engaging portion 124c and an apparatus-side fourth engaging portion provided corresponding to the cartridge-side fourth engaging portion 124 d. In other words, the tape printing apparatus 1 may be provided on the + Y side and the-Y side, in addition to the two apparatus-side engaging portions 49 facing each other on the + X side and the-X side as in the above-described embodiment.

In this configuration, when the first tape cartridge 101a is mounted in the cartridge mounting unit 2, the cartridge-side third engaging portion 124c and the cartridge-side fourth engaging portion 124d engage with the apparatus-side third engaging portion and the apparatus-side fourth engaging portion, respectively, so that the first torque switching mechanism 31 changes the state from the second state to the first state. In this way, the first tape cassette 101a includes the first cartridge-side engagement portion 124a, the second cartridge-side engagement portion 124b, the third cartridge-side engagement portion 124c, and the fourth cartridge-side engagement portion 124d, and thus can correspond to both the tape printing apparatus 1 including the first device-side engagement portion 49a and the second device-side engagement portion 49b and the tape printing apparatus 1 including the third device-side engagement portion and the fourth device-side engagement portion. Therefore, the tape printing apparatus 1 may be configured to include the apparatus-side first engagement portion 49a and the apparatus-side second engagement portion 49b as the apparatus-side engagement portion 49, or may be configured to include the apparatus-side third engagement portion and the apparatus-side fourth engagement portion, and therefore, the degree of freedom in the arrangement of the apparatus-side engagement portion 49 can be increased.

The first tape cassette 101a may be configured to include only the cassette-side first engaging portion 124a and the cassette-side second engaging portion 124b of the four cassette-side engaging portions 124 for the tape printing apparatus 1 including the apparatus-side first engaging portion 49a and the apparatus-side second engaging portion 49 b. The first tape cassette 101a may be configured to include only the cassette-side third engagement portion 124c and the cassette-side fourth engagement portion 124d of the four cassette-side engagement portions 124 for the tape printing apparatus 1 including the apparatus-side third engagement portion and the apparatus-side fourth engagement portion.

The number of the device-side engaging portions 49 is not limited to two, and may be one, or three or more. The number of cartridge-side engaging portions 124 is not limited to four. For example, when the number of the apparatus-side engaging portions 49 is two, the number of the cartridge-side engaging portions 124 may be two or more, and further, if a configuration is adopted in which one cartridge-side engaging portion 124 is engaged with two apparatus-side engaging portions 49, the number of the cartridge-side engaging portions 124 may be one.

The tape cassette 101 may be configured to include an accessory mounting portion instead of the base concave portion 116 in which the cassette-side engaging portion 124 is formed, and to detachably mount the accessory in which the base concave portion 116 in which the cassette-side engaging portion 124 is formed is provided. In this configuration, the accessory functions as an adjustment device for engaging with the device-side engagement portion 49 when the accessory is mounted on the accessory mounting portion of the tape cartridge 101. In this case, a cartridge system including the tape cartridge 101 and a component mounted on the component mounting portion of the tape cartridge 101 may be mounted on the cartridge mounting portion 2, or the tape cartridge 101 may be mounted on the cartridge mounting portion 2 after the component is mounted on the core protrusion 5 of the tape printing apparatus 1 in advance. The metal fitting may have a shape such that a flange portion is provided on the depth side in the mounting direction to supplement a portion of the wall portion of the first cartridge case 106.

The cartridge mounting section 2 is not limited to a structure in which the tape cartridge 101 and the ink ribbon cartridge 201 are mounted alternatively, and may be a structure in which only the tape cartridge 101 is mounted.

Further, the above-described embodiments and modifications may be combined.

According to this configuration, when the cartridge is mounted to the cartridge mounting portion, the torque switching mechanism changes the state from the second state to the first state or from the first state to the second state by the engagement of the cartridge-side engagement portion with the apparatus-side engagement portion. Thereby, the torque transmitted to the winding rotor is switched from the second torque to the first torque, or from the first torque to the second torque. Therefore, the winding rotor does not need to have a double-cylinder structure, the diameter of the winding core can be reduced, and the cartridge can be miniaturized.

In this case, it is preferable that the tape printing apparatus includes, as the apparatus-side engaging portion, an apparatus-side first engaging portion and an apparatus-side second engaging portion, and the cartridge includes, as the cartridge-side engaging portion, a cartridge-side first engaging portion provided corresponding to the apparatus-side first engaging portion and a cartridge-side second engaging portion provided corresponding to the apparatus-side second engaging portion, the cartridge-side first engaging portion and the cartridge-side second engaging portion being provided point-symmetrically with respect to a center of the core recess when viewed from the mounting direction.

The two engaging portions are disposed in point symmetry with respect to the center of the core recess. Therefore, the load due to the engagement acts on the cartridge in a balanced manner, and the running performance of the printing tape and the ink ribbon can be improved while suppressing the inclination of the cartridge with respect to the cartridge mounting portion.

In this case, it is preferable that the other tape printing apparatus includes, as the apparatus side engaging portion, an apparatus side third engaging portion and an apparatus side fourth engaging portion, and the cartridge includes, as the cartridge side engaging portion, a cartridge side first engaging portion, a cartridge side second engaging portion, a cartridge side third engaging portion, and a cartridge side fourth engaging portion, the cartridge side third engaging portion being provided corresponding to the apparatus side third engaging portion, the cartridge side fourth engaging portion being provided corresponding to the apparatus side fourth engaging portion, and the cartridge side third engaging portion and the cartridge side fourth engaging portion being provided so as to be point-symmetric with respect to a center of the core concave portion when viewed from the mounting direction.

In this case, it is preferable that the cartridge-side engaging portion is provided on an inner peripheral surface of the core recessed portion.

According to this configuration, even when the cartridge drops, the cartridge-side engagement portion can be prevented from being damaged.

In this case, it is preferable that the cartridge-side engaging portion is provided at an edge portion of the core recessed portion, and partially overlaps the core recessed portion when viewed from the attachment direction.

According to this configuration, when the cartridge is mounted in the cartridge mounting portion, the torque switching mechanism changes the state from the second state to the first state or from the first state to the second state by the engagement of the cartridge-side engagement portion with the apparatus-side engagement portion. Thereby, the torque transmitted to the winding rotor is switched from the second torque to the first torque, or from the first torque to the second torque. Therefore, the winding rotor does not need to have a double-cylinder structure, the diameter of the winding core can be reduced, and the cartridge can be miniaturized.

In this case, it is preferable that either one of the first cartridge and the second cartridge includes, as a cartridge side engaging portion, a cartridge side first engaging portion and a cartridge side second engaging portion, and the tape printing apparatus includes, as a device side engaging portion, a device side first engaging portion provided corresponding to the cartridge side first engaging portion and a device side second engaging portion provided corresponding to the cartridge side second engaging portion, the device side first engaging portion and the device side second engaging portion being provided so as to be point-symmetric with respect to a center of the core convex portion when viewed from the mounting direction in a state where the cartridge is not mounted.

According to this configuration, the cartridge and the torque switching mechanism are not engaged at only one location, but are engaged at two locations, namely, the cartridge-side first engagement portion and the device-side first engagement portion, and the cartridge-side second engagement portion and the device-side second engagement portion. The two engaging portions are arranged in point symmetry with respect to the center of the core convex portion. Therefore, the load due to the engagement acts on the cartridge in a balanced manner, and the running performance of the printing tape and the ink ribbon can be improved while suppressing the inclination of the cartridge with respect to the cartridge mounting portion.

In this case, preferably, the torque switching mechanism includes: a first winding gear that is provided on the same shaft as the winding rotor and rotates the winding rotor; a second winding gear that is provided on the same shaft as the winding rotor, receives the rotation of the feed motor in both the first state and the second state, and rotates the winding rotor via the first winding gear; a first torque limiter that limits torque transmitted from the first winding gear to the winding rotor to a first torque; a second torque limiter that limits torque transmitted from the second winding gear to the first winding gear to a second torque; and a movable gear configured to be engageable with and disengageable from the first winding gear, wherein the switching actuator engages the movable gear with the first winding gear when the cartridge-side engagement portion is engaged with the apparatus-side engagement portion, and disengages the movable gear from the first winding gear when the cartridge-side engagement portion is disengaged from the apparatus-side engagement portion.

According to this configuration, the cartridge-side engagement portion is engaged with the apparatus-side engagement portion, the movable gear is engaged with the first take-up gear, and the torque switching mechanism changes the state to the first state in which the rotation of the feed motor is input to the first take-up gear via the movable gear.
