Detailed Description

Hereinafter, an embodiment of a printer will be described with reference to the drawings. The printer is an ink jet printer that prints characters and images by ejecting ink onto a medium such as paper.

In the drawings, it is assumed that the printer 11 is placed on a horizontal plane, and the direction of gravity is represented by the Z axis, and the directions along the horizontal plane are represented by the X axis and the Y axis. The X, Y, and Z axes are orthogonal to each other. In the following description, the direction along the X axis is also referred to as a first direction D1 and a second direction D2 opposite to the first direction D1, and the direction along the Y axis is also referred to as a front and a rear opposite to the front. The Z axis is a vertical direction, and a direction along the Z axis is also referred to as a downward direction in the vertical direction and an upward direction in the vertical direction opposite to the downward direction in the vertical direction.

As shown in fig. 1, the printer 11 includes a rectangular parallelepiped housing 12. The printer 11 includes a carriage 15, and an ejection head 13 that ejects ink and an ink storage unit 14 that stores ink supplied to the ejection head 13 are mounted on the carriage 15. The printer 11 includes a cover member 16 provided on the carriage 15. The ink storage unit 14 is detachably mounted on the carriage 15.

A discharge port 19 for discharging the printed medium 18 is formed in the front surface, which is a front side surface of the casing 12. The discharge port 19 has a shape that enables the medium 18 to be discharged and prevents foreign matter from entering the housing 12, and the discharge port 19 in the present embodiment has a slit shape with a small gap in the vertical direction.

The case 12 may have an opening 21. The opening 21 is positioned vertically above the carriage 15 at the ink supply position SP, and when viewed vertically from above, the opening 21 overlaps the carriage 15 at the ink supply position SP where the user can supply ink to the ink reservoir 14. When the carriage 15 is located at the ink supply position SP, the cover member 16 can be rotated to a first position P1 shown in fig. 2 and a second position P2 shown in fig. 1.

The shaft of the lid member 16 is positioned at the front end of the lid member 16 in parallel with the X-axis in the state where the lid member 16 is positioned at the first position P1. The cap member 16 located at the first position P1 restricts the ink storage portion 14 from coming off the carriage 15. The cap member 16 at the second position P2 allows the ink storage portion 14 to come off the carriage 15.

In a state where the lid member 16 is located at the second position P2, the ink storage portion 14 mounted on the carriage 15 is pulled out upward in the vertical direction and is detached from the carriage 15. The ink reservoir 14 is mounted on the carriage 15 by pushing the ink reservoir 14 from a position above the carriage 15 in the vertical direction toward a position below the carriage 15 in the vertical direction. The cover member 16 located at the second position P2 may interfere with the opening 21 to restrict the movement of the carriage 15.

The printer cover 23, the rear cover 24 positioned rearward of the printer cover 23, and the operation panel 25 positioned in the first direction D1 with respect to the printer cover 23 may be provided on the upper surface, which is the upper surface of the housing 12 in the vertical direction. The printer cover 23, the rear cover 24, and the operation panel 25 of the present embodiment each have an axis parallel to the X axis, and are rotatable about the axis.

The printer cover 23 can be rotated to a cover position CP shown by a solid line in fig. 4 and an open position OP shown in fig. 1 different from the cover position CP. The printer cover 23 rotates about an axis located at an end portion of the printer cover 23 located rearward in a state where the printer cover 23 is located at the covering position CP. The printer cover 23 located at the covering position CP covers the opening portion 21. The printer cover 23 located at the open position OP exposes the opening 21. When the printer cover 23 is located at the open position OP, ink can be supplied to the ink reservoir 14 through the opening 21. That is, when the printer cover 23 is located at the open position OP, the user can supply ink to the ink reservoir 14 through the opening 21.

The rear cover 24 is rotatable to a closed position shown in fig. 1 and an open position not shown. The rear cover 24 rotates about a shaft located at the rear end of the rear cover 24 in a state where the rear cover 24 is located at the closed position. The user can fill the space opened when the back cover 24 is in the open position with the medium 18 and wind the cylindrical roll body R shown in fig. 4.

The operation panel 25 is rotated between a standing position shown in fig. 1 and a not-shown lowered position which is lowered backward from the standing position. The axis of the operation panel 25 is located at the front end. The operation panel 25 located at the standing position faces forward.

As shown in fig. 2, the ink storage portion 14 has a supply port 27. The supply port 27 is open on the upper surface, which is the upper surface of the ink reservoir 14 in the vertical direction. The printer 11 of the present embodiment is a color printer that prints by mounting a plurality of ink storage units 14 storing different types of inks on a carriage 15 and ejecting a plurality of types of inks. The carriage 15 carries a plurality of ink storing portions 14 arranged in the first direction D1, and moves in the first direction D1 and the second direction D2.

Specifically, in the carriage 15, the ink reservoir portion, which is mounted on the side closest to the first direction D1 among the plurality of ink reservoir portions 14, is the first ink reservoir portion 14a that stores ink and black ink as an example of the first ink. A second ink reservoir 14b for storing magenta ink, which is an example of the second ink, a third ink reservoir 14c for storing yellow ink, and a fourth ink reservoir 14D for storing cyan ink are mounted on the carriage 15 in this order from the first ink reservoir 14a in the second direction D2.

The first ink reservoir 14a has a first supply port 27a as an example of a supply port. The second ink storage portion 14b has a second supply port 27 b. The third ink storage portion 14c has a third supply port 27 c. The fourth ink storage portion 14d has a fourth supply port 27 d. The first to fourth supply ports 27a to 27D are located at the same position in the vertical direction and are arranged in the first direction D1.

The first to fourth ink storage portions 14a to 14d are identical in structure except for the kind of ink to be stored. Therefore, in the following description, one ink reservoir 14 of the first to fourth ink reservoirs 14a to 14d will be described.

The ink reservoir 14 may be provided with a plug 29 for closing the supply port 27. The plug 29 is provided to be detachable from the supply port 27. The plug 29 may be connected to any one of the ink storage unit 14, the cap member 16, and the carriage 15.

The cover member 16 has a first portion 31 and a second portion 32. The lid part 16 may also have a third portion 33. The first portion 31 is an upper wall located vertically above the ink reservoir 14 when the cover member 16 is located at the first position P1. The second portion 32 and the third portion 33 are portions aligned in the first direction D1 with the supply port 27 among the side walls aligned in the horizontal direction with the ink storage portion 14 when the lid member 16 is located at the first position P1. In the figures, the second portion 32 and the third portion 33 are indicated by dots.

In the cover member 16 located at the first position P1, the first portion 31 is located vertically above the ink reservoir 14. Therefore, when viewed from above in the vertical direction, the first portion 31 overlaps the ink reservoir 14, and the first portion 31 restricts the ink reservoir 14 from moving in the vertical direction.

The lid member 16 has a notch 35 cut out from the front end in the state of being located at the first position P1 to a position behind the supply port 27. The first portion 31 located rearward of the notch portion 35 is located rearward of the supply port 27. Therefore, the lid member 16 located at the first position P1 exposes the supply port 27 for supplying the ink to the ink storage portion 14 upward in the vertical direction.

As shown in fig. 3, in the lid member 16 located at the first position P1, the upper end 32a of the second portion 32 is located vertically above the first to fourth supply ports 27a to 27d, and the lower end 32b of the second portion 32 is located vertically below the first to fourth supply ports 27a to 27 d. In the lid member 16 located at the first position P1, the upper end 33a of the third portion 33 is located vertically above the first to fourth supply ports 27a to 27d, and the lower end 33b of the third portion 33 is located vertically below the first to fourth supply ports 27a to 27 d.

The second portion 32 and the third portion 33 sandwich the first to fourth supply ports 27a to 27D in the first direction D1, which is the direction in which the first to fourth supply ports 27a to 27D are arranged. Therefore, the first to fourth supply ports 27a to 27D are blocked by the second portion 32 of the lid member 16 located at the first position P1 when viewed from the first direction D1. The first to fourth supply ports 27a to 27D are blocked by the third portion 33 of the lid member 16 located at the first position P1 when viewed from the second direction D2.

As shown in fig. 2 and 3, the printer 11 includes a guide shaft 37 that supports the carriage 15. The carriage 15 moves along the guide shaft 37 to a home position HP and a return position RP, which is a position closer to the first direction D1 side than the home position HP. The carriage 15 is provided to be capable of reciprocating between a home position HP and a return position RP. In the first direction D1, a transport region TA for transporting the medium 18 from which the ink is ejected and an ink supply position SP are provided between the home position HP and the return position RP. The conveyance area TA is an area through which the medium 18 of the maximum size that can be printed by the printer 11 passes. The ink supply position SP is located between the transport area TA and the home position HP in the first direction D1.

The printer 11 includes a cap 39 provided below the home position HP in the vertical direction. The cap 39 covers the ejection head 13 when the carriage 15 is located at the home position HP.

When the lid member 16 is located at the first position P1, the second portion 32 is located closer to the first direction D1 than the first to fourth ink reservoirs 14a to 14D. When the carriage 15 is located at the ink supply position SP and the cap member 16 is located at the first position P1, the second portion 32 is located between the conveyance area TA and the supply port 27 in the first direction D1 in which the carriage 15 moves.

When the lid member 16 is located at the first position P1, the third portion 33 is located closer to the second direction D2 than the first to fourth ink reservoirs 14a to 14D. When the carriage 15 is located at the ink supply position SP and the cap member 16 is located at the first position P1, the third portion 33 is located between the cap 39 and the supply port 27 in the first direction D1 in which the carriage 15 moves.

As shown in fig. 3, the discharge head 13 has a plurality of nozzles 42 opening on a nozzle surface 41. The printer 11 may include a waste liquid tank 43 for storing waste liquid, a pipe 44 for connecting the cap 39 and the waste liquid tank 43, and a suction pump 45 for reducing the pressure in the cap 39 via the pipe 44. When the discharge head 13 is subjected to suction cleaning, the suction pump 45 is driven in a state where the cap 39 is brought into contact with the discharge head 13, and a negative pressure is applied to the nozzle 42. In the suction cleaning, ink and air bubbles thickened in the ejection head 13 can be discharged. The ink discharged from the nozzle 42 is contained in the waste liquid tank 43 as waste liquid.

The carriage 15 may be provided with an ink flow path 47. The carriage 15 may include a plurality of ink flow paths 47. The ink flow path 47 is located below the supply port 27 in the vertical direction, and discharges ink that has not been supplied to the ink storage unit 14 and leaked from the ink storage unit 14 to the outside of the carriage 15. The printer 11 may be configured such that the waste liquid tank 43 is provided below the ink supply position SP in the vertical direction, and the ink discharged through the ink flow path 47 is stored in the waste liquid tank 43.

As shown in fig. 4, the printer 11 includes: a guide member 49 that guides the medium 18 drawn out from the roll body R, a transport unit 50 that transports the medium 18 in the transport area TA, and a support table 51 that supports the medium 18 transported by the transport unit 50. The transport unit 50 transports the medium 18 drawn out from the roll body R downstream in the transport direction. In the present embodiment, the conveyance direction refers to a direction in which the medium 18 is conveyed along a member provided in the printer 11, such as the guide member 49 and the support base 51. The conveying unit 50 includes a conveying roller pair 52 provided between the guide member 49 and the support table 51 in the conveying direction, and a discharge roller pair 53 provided between the support table 51 and the discharge port 19 in the conveying direction. The conveying roller pair 52 and the discharge roller pair 53 convey the medium 18 by rotating in a state where the medium 18 is sandwiched.

The transport unit 50 transports the medium 18 drawn from the roll body R downstream in the transport direction, and discharges the medium 18 from the discharge port 19 in the discharge direction. The discharge port 19 is located at a position forward of a printing position where the discharge head 13 moving together with the carriage 15 prints on the medium 18. The transport unit 50 transports the medium 18 located at the printing position forward, and discharges the medium forward from the discharge port 19. That is, the transport direction and the discharge direction at the printing position coincide with the front.

The printer 11 includes a control unit 55 that totally controls the driving of each mechanism in the printer 11. The control unit 55 is configured by a processing circuit including a computer and a memory, for example. The control unit 55 controls various operations executed by the printer 11 in accordance with a program stored in the memory.

The operation of the present embodiment will be described.

In a standby state where printing is not performed, the carriage 15 is located at the home position HP.

As shown in fig. 2, when ink is supplied from the supply port 27 to the ink storage portion 14, the control portion 55 moves the carriage 15 to the ink supply position SP.

As shown in fig. 5, when the printer cover 23 is at the open position OP, the supply port 27 is exposed regardless of the position of the cover member 16. That is, the plug 29 can be removed while keeping the lid member 16 at the first position P1. The user can supply the ink to the ink storage portion 14 by inserting the container 57 containing the ink into the supply port 27, for example, with the cap member 16 positioned at the first position P1.

When the plug 29 is attached and detached, when the container 57 is inserted into the supply port 27, when the container 57 is pulled out from the supply port 27, or the like, ink adhering to the plug 29, the container 57, or the like may be scattered around the supply port 27.

The ink scattered to the upper side of the supply port 27 in the vertical direction drops by gravity and adheres to the upper surface of the ink storage portion 14. The ink scattered to the position closer to the first direction D1 than the supply port 27 adheres to the second portion 32. The ink scattered to the position closer to the second direction D2 than the supply port 27 adheres to the third portion 33.

As shown in fig. 6, when the scattered ink is cleaned, the lid member 16 is positioned at the second position P2. In the lid member 16 located at the second position P2, the first portion 31, the second portion 32, and the third portion 33 are located vertically above the first to fourth supply ports 27a to 27d so that the second portion 32 faces the third portion 33. Therefore, the ink adhering to the cap member 16 and the ink storage portion 14 can be easily cleaned.

The effects of the present embodiment will be described.

(1) The cover member 16 is rotatable to a first position P1 that restricts the ink storage portion 14 from coming off the carriage 15 and a second position P2 that allows the ink storage portion 14 to come off the carriage 15. In the lid member 16 located at the first position P1, the first portion 31 is located above the ink reservoir 14 in the vertical direction, and the lower end 32b of the second portion 32 is located below the supply port 27 in the vertical direction. Therefore, the cap member 16 covers the supply port 27 when viewed in the horizontal direction, and easily receives the scattered ink. In the lid member 16 located at the second position P2, since the first portion 31 and the second portion 32 are located above the supply port 27 in the vertical direction, ink adhering to the lid member 16 can be easily cleaned. This makes it possible to easily clean the ink that has scattered.

(2) The housing 12 is provided with a printer cover 23 covering the opening 21. Therefore, even if the supply port 27 is exposed regardless of the position of the cover member 16, since the supply port 27 is covered by the printer cover 23 located at the covering position CP, it is possible to reduce the possibility that foreign matter adheres to the supply port 27 or that foreign matter enters the ink storage portion 14 through the supply port 27.

(3) When the carriage 15 is located at the ink supply position SP, the second portion 32 of the cover member 16 is located between the transport area TA and the supply port 27. Therefore, the risk of contamination of the transfer area TA with ink scattered at the supply port 27 can be reduced.

(4) The first supply port 27a and the second supply port 27b are sandwiched between the second portion 32 and the third portion 33 of the lid member 16 located at the first position P1. Thus, ink scattering from the first supply port 27a or the second supply port 27b in the first direction D1 can be blocked by the second portion 32, and ink scattering in the second direction D2 opposite to the first direction D1 can be blocked by the third portion 33.

(5) The carriage 15 includes an ink flow path 47. Therefore, even when the first ink supplied to the first ink storage portion 14a leaks, for example, the first ink can be discharged to the outside of the carriage 15 through the ink flow path 47, and the possibility that the first ink enters the second ink storage portion 14b can be reduced. That is, even when the plurality of ink storage portions 14 store different types of inks, it is possible to reduce the possibility of mixing of the different types of inks.

This embodiment can be modified as follows. The present embodiment and the following modifications can be implemented in combination within a range not technically contradictory to each other.

The printer 11 may be a monochrome printer that prints by mounting 1 ink storage unit 14 on the carriage 15 and ejecting 1 type of ink. The printer 11 may be a printer that carries 2 ink storage units 14 on the carriage 15 and performs two-color printing by discharging 2 types of ink. That is, the carriage 15 may be equipped with a first ink storage portion 14a having the first supply port 27a and storing the first ink and a second ink storage portion 14b having the second supply port 27b and storing the second ink. The number of the ink storage portions 14 mounted on the carriage 15 may be 3, or 5 or more.

The ink flow path 47 is not limited to be provided on the bottom wall of the carriage 15, and may be provided on a side wall of the carriage 15. If the ink flow path 47 is provided below the supply port 27 in the vertical direction, ink that has leaked from the supply port 27 and moved downward in the vertical direction can be discharged to the outside of the carriage 15.

The printer 11 may include an absorbing material provided in the carriage 15. The absorbing material may be provided so as to individually correspond to the plurality of ink reservoirs 14. The absorbent material may also be made to absorb leaked ink. A part of the absorbing material may be disposed outside the carriage 15 to form an ink flow path for discharging the ink to the outside of the carriage 15 through the absorbing material.

When the carriage 15 is located at the ink supply position SP, the ink flow path 47 may be located above the cap 39 in the vertical direction. The cap 39 may contain ink discharged to the outside of the carriage 15 via the ink flow path 47.

In the cover member 16 located at the first position P1, the second portion 32 may be located between the first supply port 27a and the side wall of the carriage 15 in the first direction D1. In the cover member 16 located at the first position P1, the third portion 33 may be located between the fourth supply port 27D and the side wall of the carriage 15 in the first direction D1.

In the lid member 16 located at the first position P1, the second portion 32 may be located closer to the second direction D2 than at least 1 of the first to fourth supply ports 27a to 27D. For example, the second portion 32 may be located at any one of the positions between the first supply port 27a and the second supply port 27b, between the second supply port 27b and the third supply port 27c, and between the third supply port 27c and the fourth supply port 27 d. The third portion 33 located closer to the second direction D2 than the fourth supply port 27D may function as the second portion.

The second portion 32 may be provided in front of or behind the supply port 27.

The supply of ink to the ink storage unit 14 may be performed at the home position HP. When the ink is supplied from the supply port 27 to the ink storage unit 14, the control unit 55 may cause the carriage 15 to stand by at the home position HP.

The following describes the technical means and effects thereof grasped from the above-described embodiment and modifications.

(A) The printer includes: a carriage on which an ejection head that ejects ink and an ink storage unit that stores the ink supplied to the ejection head are mounted and which moves along a guide shaft; and a cover member provided on the carriage, the ink storage portion being detachable from the carriage, the cover member being rotatable to a first position and a second position, the cover member being positioned at the first position to expose a supply port of the ink storage portion, the cover member being positioned at the first position, a first portion being positioned above the ink storage portion in a vertical direction to restrict the ink storage portion from coming off the carriage, a lower end of a second portion being positioned below the supply port in the vertical direction, the cover member being positioned at the second position to allow the ink storage portion to come off the carriage, and the cover member being positioned at the second position, the first portion and the second portion being positioned above the supply port in the vertical direction.

According to this configuration, the cover member can be rotated to a first position that restricts the ink storage portion from coming off the carriage and a second position that allows the ink storage portion to come off the carriage. In the cover member located at the first position, the first portion is located above the ink reservoir in the vertical direction, and the lower end of the second portion is located below the supply port in the vertical direction. Therefore, the cover member covers the supply port when viewed in the horizontal direction, and easily receives the scattered ink. In the cover member located at the second position, since the first portion and the second portion are located above the supply port in the vertical direction, the ink adhering to the cover member can be easily cleaned. This makes it possible to easily clean the ink that has scattered.

(B) The printer may include: a control unit that moves the carriage to an ink supply position when the ink is supplied from the supply port to the ink storage unit; a housing having an opening located above the ink supply position in a vertical direction; and a printer cover provided in the housing and movable to a covering position for covering the opening portion and an opening position different from the covering position, wherein the supply port is exposed regardless of a position of the cover member when the printer cover is at the opening position.

According to this configuration, the housing is provided with the printer cover that covers the opening portion. Therefore, even when the supply port is exposed regardless of the position of the cover member, the supply port is covered by the printer cover located at the covering position, and thus, it is possible to reduce the risk of foreign matter adhering to the supply port or foreign matter entering the ink storage portion through the supply port.

(C) The printer may further include a transport unit that transports the medium from which the ink is ejected, and the second portion may be located between a transport region in which the medium is transported by the transport unit and the supply port in a direction in which the carriage moves when the carriage is located at the ink supply position and the cover member is located at the first position.

According to this configuration, when the carriage is located at the ink supply position, the second portion of the cover member is located between the conveyance area and the supply port. Therefore, the risk of contamination of the transfer area by ink scattered at the supply port can be reduced.

(D) In the printer, the ink reservoir may be a first ink reservoir having a first supply port as the supply port, the carriage is mounted with the first ink storage portion and a second ink storage portion having a second supply port, and moves in a first direction and a second direction opposite to the first direction, in the cap member located at the first position, the lower end of the second portion located in the first direction with respect to the first ink reservoir and the second ink reservoir is located vertically below the first supply port and the second supply port, and the lower end of a third portion located in the second direction with respect to the first ink reservoir and the second ink reservoir is located vertically below the first supply port and the second supply port.

According to this structure, the first supply port and the second supply port are sandwiched between the second portion and the third portion of the cover member located at the first position. Thus, ink that is scattered in a first direction from the first supply port or the second supply port can be blocked by the second portion, and ink that is scattered in a second direction opposite to the first direction can be blocked by the third portion.

(E) In the printer, the first ink storage unit may store a first ink as the ink, the second ink storage unit may store a second ink, and the carriage may include an ink flow path that discharges the first ink leaked from the first ink storage unit or the second ink leaked from the second ink storage unit to the outside of the carriage.

According to this configuration, the carriage includes the ink flow path. Therefore, even when the first ink supplied to the first ink storage portion leaks, for example, the first ink can be discharged to the outside of the carriage through the ink flow path, and the risk of the first ink entering the second ink storage portion can be reduced. That is, even when the plurality of ink storage portions store different types of inks, it is possible to reduce the possibility of mixing of the different types of inks.

(F) In the printer, the ink storage unit may be a first ink storage unit that stores a first ink as the ink, the carriage may be mounted with the first ink storage unit and a second ink storage unit that stores a second ink, and may move in a first direction and a second direction opposite to the first direction, and the carriage may include an ink flow path that discharges the first ink leaked from the first ink storage unit or the second ink leaked from the second ink storage unit to the outside of the carriage.

With this configuration, the same effects as those of the printer can be achieved.
