Technical Field

One aspect of the present invention relates to a photographing apparatus and the like.

Background

There has been an infrared camera including: a light emitting unit for irradiating an object with infrared rays; a lens for condensing infrared light reflected from an object; and an imaging element for imaging the condensed light. In such an infrared camera, it is necessary to align the optical axis by positioning the imaging element and the lens with respect to a base as a housing. For example, patent document 1 discloses the following structure: a positioning protrusion is formed on the base and is fitted into the through hole of the substrate to perform positioning.

Patent document 1: international publication No. 2016/017682

However, since the conventional structure requires high rigidity, the positioning protrusion is formed on the base made of metal, and thus the processing is not easy. Therefore, if a structure capable of performing highly accurate positioning is desired, machining may be difficult.

Disclosure of Invention

The present invention adopts the following technical means to solve the above problems. In the following description, for the purpose of facilitating understanding of the present invention, reference numerals and the like in the drawings are provided with parentheses, but the respective structural members of the present invention are not limited to these labeled structural members, and should be interpreted broadly as a range that can be technically understood by those skilled in the art.

One aspect of the present invention, a photographing apparatus,

comprising:

a base (2) as a frame body;

a substrate (3) on which an imaging element (31) is mounted; and

a lens unit having a lens barrel (4, 104) holding a lens,

the substrate has a plurality of through holes (3a, 3b, 3e, 3f) into which the plurality of projections are inserted, respectively,

the base has a hole portion (21a, 22a) into which at least one (5a, 5b) of the plurality of protrusions is inserted.

In the imaging apparatus according to the present invention, although the base as the housing is required to have high rigidity, the lens unit is not required to have high rigidity as the base, and therefore, the lens unit is easier to process than the base. In the imaging device having the above configuration, instead of providing the positioning projection on the base, a convex portion for positioning is provided on the lens unit which is easier to process than the base. Therefore, the projection for positioning can be formed relatively easily as compared with the conventional structure. This makes it possible to position the imaging element, the base, and the lens unit mounted on the substrate with high accuracy while achieving a low-cost configuration.

In the above-described photographing device, it is preferable that,

the substrate is also provided with infrared light emitting members (32, 33) for emitting infrared light,

In the above-described photographing device, it is preferable that,

the reflector (5, 105) is formed of resin.

In the imaging device having the above configuration, since the reflector is formed of resin which is easy to process, the convex portion for positioning can be formed with simple and high processing accuracy.

In the above-described photographing device, it is preferable that,

the base (2) is formed of metal and is in contact with the infrared light emitting member.

In the imaging device having the above configuration, since the infrared light emitting member that emits heat is in contact with the base made of metal, it is possible to form a configuration that suppresses heat generated by the infrared light emitting member from being dispersed and locally generating high heat.

In the above-described photographing device, it is preferable that,

the convex parts include a first convex part, a second convex part, a third convex part and a fourth convex part,

the first convex portion (5a) and the second convex portion (5b) are formed on the reflector (5),

the third convex portion (4a) and the fourth convex portion (4b) are formed in the lens barrel (4).

In the imaging device having the above configuration, the positions of the reflector and the lens barrel with respect to the substrate and the base can be appropriately adjusted.

In the above-described photographing device, it is preferable that,

the convex portions include a first convex portion and a second convex portion,

the first convex portion (5a) and the second convex portion (5b) are formed in the reflector (105), and the lens barrel (104) is supported by the reflector.

Detailed Description

One of the features of the imaging device of the present invention is: the substrate, the base, and the lens unit are adjusted in position by forming a through hole in the substrate, forming a hole in the base, and inserting a projection formed on the lens unit into the through hole and the hole.

In this specification, the center position of the lens, that is, the center position of light incident on the image pickup element is referred to as an "optical axis". An object to be photographed located on the opposite side of the imaging element with respect to the lens is referred to as an "object". The direction in which the subject is located with respect to the lens is sometimes referred to as "optical axis direction front" or "front side". The direction in which the imaging element is located with respect to the lens is sometimes referred to as "optical axis direction rear" or "rear side". In each drawing, an X axis, a Y axis, and a Z axis are shown to be orthogonal to each other. The Z axis is a direction parallel to the extending direction of the optical axis.

The embodiments of the present invention will be specifically described based on the following configurations. However, the embodiment described below is merely an example of the present invention and is not to be construed as limiting the technical scope of the present invention. In the drawings, the same constituent elements are denoted by the same reference numerals, and the description thereof may be omitted.

< 1> embodiment 1>

Embodiment 1 of the present invention will be described with reference to fig. 1 to 3. Fig. 1 is an external perspective view of the imaging device according to the present embodiment as viewed from the front side in the optical axis direction. Fig. 2 is an exploded perspective view of the imaging device of the present embodiment as viewed from the front side in the optical axis direction. Fig. 3 is a sectional view of the imaging apparatus of the present embodiment.

As shown in fig. 1 to 3, the imaging device of the present embodiment includes: a housing 1, a base 2, a substrate 3, a lens barrel 4, and a reflector 5. The housing 1 and the base 2 are coupled to form a housing. The combination of the reflector 5 and the lens barrel 4 of the present embodiment corresponds to the "lens unit" of the present invention.

< case 1>

The housing 1 is a box-shaped member having a Y-axis-side surface opened and a Z-axis-side surface formed with a substantially rectangular opening 1d, and the housing 1 forms an internal space for accommodating the substrate 3, the lens barrel 4, and the reflector 5 together with the base 2. The housing 1 is connected to the base 2 by screws 71 to 74, and the housing 1 and the base 2 together form a frame. Groove-shaped screw holes into which the screws 71 to 74 are inserted are formed at four corners on the Y-axis side of the housing 1. Three circular openings 1a, 1b, and 1c are formed in the opening 1d of the housing 1. In the assembled state, the lens group 41 and the imaging element held by the lens barrel 4 are positioned at the tip (imaging element side) of the opening 1b, and the infrared light emitting members 32 and 33 supported by the substrate are positioned at the tip (imaging element side) of the openings 1a and 1c, respectively. In the assembled state, a cover made of glass or resin is disposed in the substantially rectangular opening 1 d.

< base 2>

The base 2 is formed of a metal material such as aluminum, and as described above, the base 2 and the housing 1 together form a frame. The base 2 is connected to the housing 1 by screws 71 to 74 so as to close the open surface on the Y-axis side of the housing 1. The base 2 has substrate contact surfaces 21 and 22 extending in a plate-like manner from the bottom surface portion, which is the Y-axis-side surface, toward the Y-axis + side.

Holes 21a and 22a are formed from the Z-axis + side toward the Z-axis-side on the substrate contact surfaces 21 and 22, respectively. Projections 5a and 5b formed on the reflector 5, which will be described later, are inserted into the holes 21a and 22a, respectively.

Note that the holes 21a and 22a in the present embodiment are through holes (see fig. 3), and the holes 21a and 22a may be groove-shaped holes instead of through holes.

Screw holes 21b and 22b as through holes through which screws 61 and 62 are inserted are formed in the substrate contact surfaces 21 and 22 on the Y-axis side of the holes 21a and 22a, respectively. Screws 61 and 62 are inserted into the screw holes 21b and 22b, respectively. The base 2 is coupled to the substrate 3 and the reflector 5 by the screws 61 and 62.

Screw holes as through holes through which screws 71 to 74 for connecting the base 2 and the housing 1 are inserted are formed near four corners of the bottom surface portion of the base 2.

A flexible substrate through hole 2a extending in the X-axis direction and penetrating in the Y-axis direction is formed at a position between the substrate contact surfaces 21 and 22 at the bottom surface portion of the base 2. A flexible substrate 34 connected to the substrate 3 is inserted into the flexible substrate through hole 2 a.

< substrate 3>

The substrate 3 is a plate-shaped member, and electronic components including the imaging element 31 and the infrared light emitting members 32 and 33 are mounted thereon.

The imaging element 31 is mounted on the substrate 3 so that the center position is the optical axis. The imaging element 31 is a photoelectric conversion element that converts irradiated light into an electric signal, and is not limited to a C-MOS sensor, a CCD, or the like. In addition, an imaging unit requiring an imaging function other than the imaging element 31 may be employed in the imaging apparatus.

The infrared light emitting members 32 and 33 are disposed on the X-axis side and the X-axis + side, respectively, with respect to the imaging element 31. The imaging element 31 and the infrared light emitting members 32 and 33 are arranged in the X-axis direction. The infrared light emitting members 32 and 33 emit light having a wavelength of infrared light when electric power is applied thereto. In the imaging device of the present embodiment, the subject is irradiated with light emitted from the infrared light emitting members 32 and 33, and the imaging element 31 receives infrared light (infrared light) reflected from the subject, thereby performing imaging.

The Z-axis + side of the infrared light emitting members 32 and 33 is in contact with the base 2 via the substrate 3. The infrared light emitting members 32 and 33 generate heat when they emit light, and are disposed in contact with the base 2 made of metal, thereby dissipating the heat. That is, the base 2 functions as a heat radiation member.

In another embodiment, a part of the terminals of the infrared light emitting member 32 may be disposed inside the substrate 3 and may be brought into contact with the base 2. This can further improve the heat radiation effect. Note that the "abutment" in the present embodiment includes a state of abutment via a member such as the substrate 3, in addition to a state of direct abutment.

A flexible substrate 34 extending to the Y-axis side is connected to the substrate 3. The Y-axis + side end of the flexible substrate 34 is connected to the substrate 3. An extension portion extending to the Y-axis side of the flexible substrate 34 is inserted through the flexible substrate through hole 2 a. The Y-axis side end of the flexible substrate 34 is connected to an external device.

A through hole 3a is formed in the substrate 3 at a position on the X-axis side of the infrared light emitting member 32. In the assembled state, the convex portion 5a of the reflector 5 is inserted into the through hole 3 a. A through hole 3b is formed in the substrate 3 at a position on the X-axis + side of the infrared light emitting member 33. In the assembled state, the convex portion 5b of the reflector 5 is inserted into the through hole 3 b.

Screw holes 3c and 3d as through holes are formed in the substrate 3 on the Y-axis side of the through hole 3a and the Y-axis side of the through hole 3b, respectively. Screws 61 and 62 are inserted into the screw holes 3c and 3d, respectively.

A hole 3e is formed in the substrate 3 at a position on the X-axis side of the imaging element 31. In the substrate 3, a hole 3f is formed at a position to be centered on the imaging element 31 and to be targeted by the hole 3 e. As shown in fig. 2, the holes 3e and 3f are formed at substantially point-symmetrical positions with respect to the optical axis. The convex portions 4a and 4b of the lens barrel 4 are inserted into the holes 3e and 3f, respectively. In the present embodiment, the holes 3e and 3f are groove-shaped holes that do not penetrate the substrate 3, but the holes 3e and 3f may be through holes that penetrate the substrate 3.

In the substrate 3, a screw hole 3g is formed at a position on the Y-axis + side of the hole 3 e. In the substrate 3, a screw hole 3h is formed at a position on the Y-axis side of the hole 3 f. Screws 63 and 64 are inserted into the screw holes 3g and 3h, respectively. The substrate 3, the lens barrel 4, and the reflector 5 are coupled by the screws 63 and 64.

< lens barrel 4>

The lens barrel 4 is disposed between the reflector 5 and the substrate 3, and holds a lens group 41 (see fig. 3). The lens barrel 4 is formed of a resin material such as polycarbonate. The lens barrel 4 is cylindrical on the Z-axis side and rectangular on the Z-axis + side. A screw thread for screwing the reflector 5 is formed radially outside the cylindrical portion of the lens barrel 4. The lens group 41 functions to condense light from the subject to the image pickup device 31 and form an image. The lens barrel 4 has axial projections 4a and 4b extending to the Z-axis + side on the Z-axis + side surface facing the substrate 3. As described above, the convex portions 4a and 4b are inserted into the holes 3e and 3f of the substrate 3, respectively.

The lens barrel 4 has screw holes 4c and 4d as through holes formed near four corners at positions where the convex portions 4a and 4b are not formed. Screws 63 and 64 are inserted into the screw holes 4c and 4d, respectively.

< Reflector 5>

The reflector 5 has three cylindrical through holes extending in the Z-axis direction, i.e., openings 5c, 5d, and 5 e. A screw thread is formed radially inside the opening 5d of the reflector 5. The lens barrel 4 is inserted into the opening 5d of the reflector 5, and the reflector 5 is screwed into the lens barrel 4. The reflector 5 is formed of a resin material such as polycarbonate, as in the lens barrel 4.

A reflecting portion including a reflecting plate that reflects infrared rays is disposed radially inward of the openings 5c and 5e of the reflector 5. In the assembled state, the infrared light emitting members 32 and 33 on the substrate 3 are positioned on the Z-axis + side of the openings 5c and 5e, respectively. The reflective portion of the opening 5c reflects light emitted from the infrared light emitting member 32, and the reflective portion of the opening 5e reflects light emitted from the infrared light emitting member 33. That is, the light emitted from the infrared light emitting members 32 and 33 is reflected by the reflecting plates and is irradiated toward the subject.

On the surface of the reflector 5 on the Z-axis + side, axial projections 5a and 5b extending to the Z-axis + side are formed. The projections 5a and 5b are inserted into the through holes 3a and 3b of the substrate 3, respectively, and further inserted into the holes 21a and 22a of the base 2.

Groove-shaped screw holes into which screws 61 and 62 are inserted are formed on the surface of the reflector 5 on the Z-axis + side (the surface facing the substrate 3).

< positioning by projections 5a, 5b, 4a, 4b >

As described above, the reflector 5 is formed with the convex portions 5a and 5b extending to the Z-axis + side, and the lens barrel 4 is formed with the convex portions 4a and 4b extending to the Z-axis + side. The projections 5a and 5b are inserted into the through holes 3a and 3b of the substrate 3, and further into the holes 21a and 22a of the base 2. This positions the susceptor 2, the substrate 3, and the reflector 5. Further, the convex portions 4a, 4b of the lens barrel 4 are inserted into the hole portions 3e, 3f of the substrate 3. This positions the substrate 3 and the lens barrel 4. By these two kinds of positioning, the base 2, the substrate 3, the lens barrel 4, and the reflector 5 are positioned.

< 2> embodiment 2>

Next, embodiment 2 of the present invention will be explained. The imaging device of the present embodiment is similar to the imaging device of embodiment 1 in all other configurations except for a configuration in which, instead of positioning the lens barrel 4 on the substrate 3, the lens barrel 104 is screwed to the reflector 105, and the reflector 105 is positioned on the substrate 3, thereby indirectly positioning the lens barrel 104. In the following description, only the differences from embodiment 1 in the present embodiment will be described, and the description of the same configurations as embodiment 1 will be omitted. In addition, the combination of the reflector 105 and the lens barrel 104 of the present embodiment corresponds to a "lens unit" of the present invention.

Fig. 4 and 5 are diagrams showing an imaging device according to the present embodiment. Fig. 4 is an exploded perspective view of the imaging device of the present embodiment as viewed from the front side in the optical axis direction. Fig. 5 is a sectional view of the imaging device of the present embodiment. The appearance of the imaging device according to the present embodiment is the same as that of fig. 1 of embodiment 1.

< Reflector 105>

The reflector 105 has three cylindrical through holes extending in the Z-axis direction, i.e., openings 5c, 105d, and 5 e. A screw thread to be screwed into the lens barrel 104 is formed radially inward of the opening 105 d. As in embodiment 1, on the surface of the reflector 5 on the Z-axis + side, projections 5a and 5b extending to the Z-axis + side are formed.

< lens barrel 104>

The lens barrel 4 is disposed on the Z-axis side of the reflector 5 and holds the lens group 41. The lens barrel 104 is cylindrical, and is inserted into the opening 105d of the reflector 105 from the Z-axis side toward the Z-axis + side (toward the imaging element side). A screw thread to be screwed into the opening 105d is formed on the radial outer side of the lens barrel 104.

< Filter 108>

An optical filter 108 is disposed between the lens group 41 held by the lens barrel 104 and the imaging element 31. The filter 108 functions to block and prevent light having a wavelength other than infrared rays, for example.

< positioning by projections 5a, 5b >

The reflector 105 of the present embodiment is formed with convex portions 5a and 5b extending to the Z-axis + side. The projections 5a and 5b are inserted into the through holes 3a and 3b of the substrate 3, and further into the holes 21a and 22a of the base 2. This positions the susceptor 2, the substrate 3, and the reflector 5. Further, since the lens barrel 104 is supported by the reflector 105, the lens group 41 held by the lens barrel 104 is also positioned with respect to the base 2 and the substrate 3.

< 3> features of the present invention

In this way, by providing the convex portion on the lens unit which is easier to process than the base, the convex portion for positioning can be formed relatively easily compared to the conventional structure. Further, the imaging element 31, the base 2, and the lens unit mounted on the substrate 3 can be positioned with high accuracy while forming a low-cost configuration.

In the imaging device according to the above embodiment, the following configuration is provided: has infrared light emitting members 32, 33 for emitting infrared light, and a reflector 5(105) for reflecting light emitted from the infrared light emitting members 32, 33.

In the imaging device according to the above embodiment, the following configuration is formed: the reflector 5(105) has an opening 1b formed so as to surround the lens closest to the subject side of the lens barrel 4 or the lens group 41. With this configuration, light from the infrared light emitting members 32 and 33 can be prevented from entering the lens barrel 4 and causing ghost images, flare, and the like.

In the imaging device according to the above embodiment, the following configuration is formed: since the reflector 5(105) is formed of resin, the convex portions 5a and 5b can be formed easily and with high accuracy.

In the imaging device according to the above embodiment, the following configuration is formed: the base 2 is made of metal and is in contact with the infrared light emitting members 32 and 33. With this configuration, it is possible to prevent heat generated from the infrared light emitting members 32 and 33 from being dispersed through the base 2 and locally generating high heat.

In the imaging device according to embodiment 1, the following configuration is provided: the reflector 5 has convex portions 5a and 5b, and the lens barrel 4 has convex portions 4a and 4 b. With this configuration, the positions of the reflector 5 and the lens barrel 4 with respect to the substrate 3 and the base 2 can be appropriately adjusted.

The imaging device according to embodiment 2 is configured as follows: the reflector 105 has convex portions 5a, 5b, and the lens barrel 104 is supported by the reflector 105. According to this configuration, the position of the reflector 105 with respect to the substrate 3 and the base 2, and further, the position of the lens barrel 104 supported by the reflector 105 can be appropriately adjusted.

In the imaging device according to the above embodiment, the following configuration is provided: the projections 5a and 5b of the reflector 5(105) are inserted into the holes 21a and 22a of the base 2. With this structure, the positions of the substrate 3, the base 2, the reflectors 5(105), and the lens barrels 4(104) can be appropriately adjusted.

In the imaging device according to the above embodiment, the following configuration is formed: the lens barrel 4(104) is screwed to the reflector 5 (105). With this configuration, the lens barrel 4(104) and the reflector 5(105) can be coupled without using any other member such as a screw, and the focus can be adjusted.

<4. supplementary items >

The embodiments of the present invention have been specifically described above. In the above description, the embodiment is described as an example, and the scope of the present invention is not limited to the embodiment, and the scope of the present invention should be construed broadly as a scope that can be grasped by a person skilled in the art.

In the imaging device of the embodiment, the infrared light emitting members 32 and 33 are used, but these light emitting members may be light emitting members capable of emitting light having a wavelength including infrared rays.

In the imaging device according to the embodiment, the base 2 is made of metal, but instead of forming the base 2 of metal, it may be formed of a rigid body having higher thermal conductivity than resin.

In the imaging device of the embodiment, the configuration in which the infrared light emitting members 32 and 33 are disposed on both sides of the imaging element 31 on the substrate 3 is exemplified, and the infrared light emitting members do not necessarily need to be two, may be one, and may be three or more.

In the imaging device of the embodiment, the reflector 5 has the two convex portions 5a and 5b as an example and has been described, but the number of convex portions may be changed arbitrarily. However, from the viewpoint of accurate positioning, a configuration in which two or more convex portions are provided is preferable.
