(First Embodiment)
The camera 10 (imaging apparatus) according to the first embodiment of the present disclosure will be described with reference to FIGS. 1 to 3. The camera 10 includes a lens group 11 (lens), a front case 12 (housing / support), an image sensor 13, a plate-shaped member 14, and a rear case 15. The plate-shaped member 14 is fixed to the front case 12 by a fixing structure. The fixed structure includes a plate-shaped member 14, a first positioning pin 16, and a second positioning pin 17 (see FIG. 2). The first positioning pin 16 and the second positioning pin 17 are a first positioning member and a second positioning member, respectively. The fixing structure may further include a positioning post 18, a mounting post 19, a substrate fastening screw 20, a spacer 21, and an imager cushion 22.

The lens group 11 includes one or more lenses constituting the imaging optical system of the camera 10. The lens group 11 is located on one side (+ z direction) of the camera 10 and directs the optical axis toward the subject. Hereinafter, the side on which the lens group 11 of the camera 10 is arranged is referred to as a front side (+ z direction). The lenses constituting the lens group 11 can have transparency to visible light. When the camera 10 is an infrared camera, the lenses constituting the lens group 11 have transparency to infrared rays in a predetermined frequency range. The light from the subject transmitted through the lens group 11 forms an image of the subject on the light receiving surface of the image sensor 13.

The front case 12 accommodates the image sensor 13 and the plate-shaped member 14 together with the rear case 15. The front case 12 holds the lens group 11 on the front side of the housing. The front case 12 has a lens holding portion 12a for holding the lens group 11 and accommodates the lens group 11. The lens holding portion 12a may have a shape suitable for the outer shape of each lens constituting the lens group 11. The front case 12 has a hollow structure that opens to the rear side (−z direction).

The rear case 15 is joined to the front case 12 to form a part of the housing of the camera 10. The rear case 15 is mainly located on the back side of the front case 12. The rear case 15 is connected after the plate-shaped member 14 is fixed to the front case 12. The rear case 15 can be made of various materials such as resin and metal.

The positioning post 18 and the mounting post 19 project from the inside of the front case 12. That is, the positioning post 18 and the mounting post 19 are fixed to the front case 12 and extend inside the front case 12. The positioning post 18 and the mounting post 19 can be formed integrally with the front case 12. The positioning post 18 and the mounting post 19 may extend from the front surface inside the front case 12 to the rear side (−z direction) along the optical axis. In one embodiment, two positioning posts 18 and two mounting posts 19 can be provided with the lens group 11 interposed therebetween. The positioning post 18 and the mounting post 19 may be fixed to the inner surface of the front case 12.

A screw hole 19a is formed at the rear end of the mounting post 19. The screw hole 19a is used to fix the plate-shaped member 14 by using the substrate fastening screw 20. FIG. 2 shows a view of the plate-shaped member 14 fastened using the substrate fastening screw 20 from the rear side.

As shown in FIG. 2, the rear ends of the two positioning posts 18 are provided with a first positioning pin 16 and a second positioning pin 17, respectively. As a more detailed example, when viewed from the rear case 15 side, the plate-shaped member 14 has a shape in which square corners are cut out. The directions along the two adjacent sides of the outer circumference of the plate-shaped member 14 are the x direction and the y direction, respectively. The first positioning pin 16 and the second positioning pin 17 are located on the diagonal line of a square with the image pickup device 13 interposed therebetween. Further, the two substrate fastening screws 20 are located on the other diagonal line. The mounting post 19 is projected at a position corresponding to this.

As shown in FIG. 3, the first positioning pin 16 has a movable portion 23 and a rigid portion 24. The movable portion 23 has elasticity and is at least partially movable in one direction (for example, in FIG. 2, a direction forming approximately 45 degrees with respect to the x direction and the y direction). The tip of the movable portion 23 away from the positioning post 18 is a hook 23a (locking portion) protruding in the movable direction. The rigid portion 24 has a higher rigidity than the movable portion 23. The rigid portion 24 may have a rigidity of 5 times or more, preferably 10 times or more, more preferably 20 times or more that of the movable portion 23. The deformation of the rigid portion 24 can be substantially ignored as compared with the deformation of the movable portion 23.

As shown in FIG. 3, the first positioning pin 16 can be formed by separating the tip portion of a single columnar member into a movable portion 23 and a rigid portion 24 by a notch. Since the cross-sectional area of the movable portion 23 shown in FIG. 3 in the direction orthogonal to the optical axis of the lens group 11 (xy direction) is smaller than the cross-sectional area of the rigid portion 24, when a force is applied in the movable direction, the movable portion 23 is more than the rigid portion 24. It can be greatly deformed. In FIG. 3, the single columnar member is columnar except for the protruding portion of the hook 23a, but may have a prismatic or other shape. The first positioning pin 16 may be formed integrally with the positioning post 18. The first positioning pin 16 is composed of a member separate from the positioning post 18, and may be fixed to the positioning post 18.

The structure of the second positioning pin 17 may be the same as or similar to the structure of the first positioning pin 16.

As shown in FIG. 2, the first direction D1 which is the movable direction of the movable portion 23 of the first positioning pin 16 and the second direction D2 which is the movable direction of the movable portion of the second positioning pin 17 intersect each other. Is. In the example of FIG. 2, the movable direction of the movable portion 23 of the first positioning pin 16 may be the diagonal direction (direction along the alternate long and short dash line P) connecting the first positioning pin 16 and the second positioning pin 17. The movable direction of the moving portion of the second positioning pin 17 may be a direction orthogonal to the diagonal direction connecting the first positioning pin 16 and the second positioning pin 17 (direction along the alternate long and short dash line Q).

The image pickup device 13 takes an image by converting the image of the subject formed by the lens group 11 into an electric signal. The image sensor 13 includes a CCD image sensor (Charge-Coupled Device Image Sensor) and a CMOS image sensor (Complementary MOS Image Sensor). The image of the subject converted into an electric signal by the image sensor 13 is output from the rear case 15 to the outside of the camera 10.

The plate-shaped member 14 is a plate-shaped member on which the image sensor 13 is mounted. The plate-shaped member 14 may mount an electronic component other than the image pickup element 13. The plate-shaped member 14 has an accommodating structure capable of accommodating the first positioning pin 16 and the second positioning pin 17. In this embodiment, the accommodating structure is a positioning hole 14a penetrating the plate-shaped member 14 (see FIGS. 2 and 4). The positioning hole 14a is provided at a position corresponding to the first positioning pin 16 and the second positioning pin 17.

The diameter of the positioning hole 14a is the width occupied by the rigid portion 24 of the first positioning pin 16 to the hook 23a of the movable portion 23 in a state where an external force is applied in a direction in which the movable portion 23 and the rigid portion 24 are brought closer to each other. Greater than. Therefore, the first positioning pin 16 can be passed through the positioning hole 14a from the surface (first surface) S1 side on which the image sensor 13 of the plate-shaped member 14 is mounted. The positioning hole 14a is a receiving structure capable of receiving the first positioning pin 16 from the first surface side. Further, the diameter of the positioning hole 14a is narrower than the width of the space where the movable portion 23 excluding the hook 23a from the rigid portion 24 of the first positioning pin 16 exists in a state where no external force is received. Therefore, when the first positioning pin 16 is passed through the positioning hole 14a to loosen the force, the movable portion 23 expands in the movable direction and presses the inner surface of the positioning hole 14a in the movable direction. As a result, the plate-shaped member 14 is offset, and the rigid portion 24 comes into contact with the surface of the positioning hole 14a opposite to the movable portion 23, so that the plate-shaped member 14 is positioned in the movable direction of the movable portion 23. Hereinafter, the surface of the positioning hole 14a that comes into contact with the rigid portion 24 is referred to as a first contact surface 14c.

The plate-shaped member 14 has a width substantially equal to or slightly narrower than the distance between the hook lower surface 23b of the hook 23a of the movable portion 23 and the upper end surface of the positioning post 18 at least in the vicinity of the positioning hole 14a. Therefore, in a state where the plate-shaped member 14 is positioned in the movable direction of the movable portion 23, the hook lower surface 23b is a surface on the side opposite to the surface on which the image sensor 13 is arranged in the vicinity of the positioning hole 14a of the plate-shaped member 14. Second surface) Engage with S2. As a result, it is possible to prevent the plate-shaped member 14 into which the first positioning pin 16 is inserted from coming off from the first positioning pin 16. The vicinity of the positioning hole 14a on the second surface S2 of the plate-shaped member 14 that comes into contact with the hook lower surface 23b is referred to as a second contact surface 14d (see FIGS. 4 to 7). The second contact surface 14d faces the direction opposite to the direction in which the first surface S1 faces. In the present application, facing in the opposite direction means that the directions of the surfaces are different by 90 degrees or more. As described above, a snap fit is formed between the plate-shaped member 14 and the first positioning pin 16. Snap-fit is a mechanical joining method in which metal or plastic is fitted and connected by utilizing the elasticity of the material. The hook 23a is a hook portion of the snap fit.

The same snap fit as between the positioning hole 14a and the first positioning pin 16 is formed between the positioning hole 14a different from the positioning hole 14a into which the first positioning pin 16 is inserted and the second positioning pin 17. You can do it.

Further, the plate-shaped member 14 has a mounting hole 14b for passing the substrate fastening screw 20 at a position corresponding to the mounting post 19.

As shown in FIG. 1, an imager cushion 22 is compressed between the image sensor 13 and the lens holding portion 12a of the front case 12 in order to prevent foreign matter from entering between the image sensor 13 and the lens group 11. It is installed in a closed state. The imager cushion 22 is a sealing member made of an elastic material such as rubber that seals the space around the image sensor 13 and the lens group 11 from an external space. The imager cushion 22 can have a hollow square shape (a shape along four sides of a square or a rectangle) along the outer circumference of the image sensor 13. The imager cushion 22 may be arranged between the plate-shaped member 14 around the image sensor 13 and the lens holding portion 12a.

A thin plate-shaped spacer for adjusting the position and inclination of the image sensor 13 in the optical axis direction (z direction) between the end surface of the mounting post 19 facing the plate-shaped member 14 and the plate-shaped member 14. 21 is arranged. The spacer 21 has a shape through which the threaded portion of the substrate fastening screw 20 is passed, and is fixed to the mounting post 19 together with the plate-shaped member 14 by the substrate fastening screw 20. For example, the spacer 21 may have an O-shape or a U-shape. As the spacer 21, a plurality of spacers 21 having different thicknesses are prepared. When mounting the plate-shaped member 14 to the mounting post 19, a spacer 21 having an appropriate thickness is selected.

Next, a method of fixing the plate-shaped member 14 to the front case 12 will be described with reference to FIGS. 4 to 7. 4 to 7 are cross-sectional views of a fixed structure including a positioning post 18 and a mounting post 19 as in FIG. 1.

First, as shown in FIG. 4, the plate-shaped member 14 is placed behind the front case 12 with the imager cushion 22 mounted on the lens holding portion 12a of the front case 12 and the spacer 21 mounted on the end face of the mounting post 19. Bring it closer to the direction of arrow A1 from the side (-z direction). At this time, when the movable portion 23 of the first positioning pin 16 is pushed in the direction of the arrow A2, the tip portion of the first positioning pin 16 is narrowed, and the first positioning pin 16 passes through the positioning hole 14a. As a result, the plate-shaped member 14 is placed on the positioning post 18 and the spacer 21 as shown in FIG. At this time, a force in the z direction is applied to the imager cushion 22 in contact with the outer periphery of the image sensor 13.

Next, when the force applied to the movable portion 23 in the direction of arrow A2 is relaxed, the movable portion 23 moves in the direction of arrow A3 due to the elastic force of the movable portion 23 and tries to return to the original shape. In FIG. 5, the movable portion 23 is inscribed in the positioning hole 14a of the plate-shaped member 14 on the lower side of the hook 23a. Further, the lower surface 23b of the hook 23a of the movable portion 23 is a second contact surface which is a part of the second surface S2 which is a surface opposite to the first surface S1 on which the image sensor 13 of the plate-shaped member 14 is mounted. It is in a state of being in contact with 14d.

Further, the movable portion 23 presses the inner surface of the positioning hole 14a in the direction of arrow A4 in FIG. As a result, the plate-shaped member 14 is pushed and moved in the direction of the arrow A4, and the rigid portion 24 of the first positioning pin 16 is the first contact surface on the inner side surface of the positioning hole 14a opposite to the movable portion 23 side. It is offset to the surface 14c and pressed. As a result, the rigid portion 24 positions the movable portion 23 of the plate-shaped member 14 in the movable direction.

The plate-shaped member 14 is also positioned by the second positioning pin 17. At this time, as shown in FIG. 2, the movable direction of the movable portion 23 of the first positioning pin 16 (first direction D1) and the movable direction of the movable portion of the second positioning pin 17 (second direction D2) are set. By setting the directions so as to intersect each other, the plate-shaped member 14 can be positioned two-dimensionally. Further, by setting the first direction D1 and the second direction D2 to be orthogonal to each other, more accurate positioning can be performed in the Cartesian coordinate system.

As described above, the plate-shaped member 14 is accurately positioned with respect to the front case 12 by the first positioning pin 16 and the second positioning pin 17. After that, as shown in FIG. 7, the plate-shaped member 14 is fixed to the mounting post 19 by screwing it with the substrate fastening screw 20. In this way, the plate-shaped member 14 is fixed to the front case 12 in a state of being positioned by the first positioning pin 16 and the second positioning pin 17. Further, in FIG. 7, when the imager cushion 22 is pressed against the outer peripheral portion of the image pickup element 13, an urging force acts on the plate-shaped member 14. However, since the plate-shaped member 14 is pressed by the lower surface 23b of the hook 23a via the second contact surface 14d, it is possible to prevent the substrate from rising and / or falling off. The imager cushion 22 is an urging member that urges the plate-shaped member 14 with respect to the hook 23a.

(Comparison example)
The fixed structure 100 when the cylindrical positioning pin 101 is simply used for positioning will be described with reference to the comparative examples shown in FIGS. 8 and 9. The fixing structure 100 shown in FIG. 8 fixes the plate-shaped member 104 on which the image pickup device 103 is mounted on the front case 102, similar to the first embodiment of the present disclosure. A pair of positioning posts 105 and mounting posts 106 are projected from the front case 102, respectively. A positioning pin 101 is provided on the upper end surface of the positioning post 105 to restrain the movement and rotation of the plate-shaped member 104 in the in-plane direction. An imager cushion 107 is arranged between the lens holding portion of the front case 102 and the image sensor 103.

In the fixed structure as shown in FIG. 8, it is necessary to form the positioning hole 104a having a diameter larger than the diameter of the positioning pin 101 in the plate-shaped member 104. Since there is no means for accurately fixing the plate-shaped member 104 to the positioning pin 101, the position of the plate-shaped member 104 shifts within the range of the gap between the positioning hole 104a and the positioning pin 101 when tightening screws or the like. Sometimes.

Further, when the plate-shaped member 104 and the spacer 109 are fixed to the mounting post 106 by the substrate fastening screw 108, a non-uniform force may be applied in the direction of compressing the imager cushion 107. At this time, the reaction force received from the imager cushion 107 may cause the image sensor 103 and the plate-shaped member 104 to tilt, and the positioning hole 104a of the plate-shaped member 104 may fall off from the positioning pin 101.

In contrast to the configuration of the comparative example as described above, in the fixed structure according to the first embodiment of the present disclosure, the plate-shaped member 14 is pushed by the movable portion 23 of the first positioning pin 16 and hits the rigid portion 24. Since it is in a state of being in contact with one side, the positioning accuracy is improved. Further, since the hook of the movable portion 23 opens with respect to the positioning hole 14a and presses the second contact surface 14d which is a part of the second surface S2 of the plate-shaped member 14, the substrate does not fall off when screwing. Can be prevented.

(Second Embodiment)
In the first embodiment, positioning pins are provided on the diagonal line of one of the plate-shaped members having a shape close to a square when viewed from the rear case 15 side, but the fixing structure of the present disclosure includes this. Not limited. The positioning pin can be placed at any position.

For example, as shown in FIG. 10, in the cross-sectional view seen from the rear case 31 side of the camera 30, it is assumed that the substantially square plate-shaped member 32 is screwed at three places by the substrate fastening screws 33. The plate-shaped member 32 is screwed by the substrate fastening screw 33 in the vicinity of each of the two adjacent vertices and in the vicinity of the center of the other two vertices. When the direction of the side connecting the vertices in which the two substrate fastening screws 33 are arranged in the vicinity is the x direction and the direction orthogonal to this is the y direction, the first positioning pin 34 and the second positioning pin 35 are different from each other. It is placed near the center of the side along the direction.

In the fixed structure as described above, when positioning, the movable portion of the first positioning pin 34 is the plate-shaped member 32 in the direction D3 (direction along the alternate long and short dash line P') of the second positioning pin 35, that is, in the x direction. Press. The movable portion of the second positioning pin 35 is a plate in the direction D4 (direction along the alternate long and short dash line Q') orthogonal to the direction D3 in which the movable portion of the first positioning pin 34 presses the plate-shaped member 32, that is, in the y direction. The shape member 32 is pressed. As a result, the plate-shaped member 32 is offset in the x direction to the rigid portion of the first positioning pin 34 and is offset in the y direction to the rigid portion of the second positioning pin 35. Thereby, the plate-shaped member 32 can be accurately positioned in the in-plane direction of the plate-shaped member 32, that is, in the xy direction.

(Third Embodiment)
A fixed structure according to still another embodiment of the present disclosure will be described with reference to FIG. The fixing structure 40 shown in FIG. 11 fixes the plate-shaped member 42 having the image pickup device 41 mounted on the front case, similar to the first embodiment. A positioning post 43 and a mounting post 44 are projected from the front case. Similar to the first embodiment, a plurality of positioning posts 43 and a plurality of mounting posts 44 can be provided. The plate-shaped member 42 is positioned by a positioning pin 45 provided at the upper end of the positioning post 43, and then screwed to the mounting post 44 via a spacer 46 using a substrate fastening screw 47.

The plate-shaped member 42 is formed with a recess 42a. The recess 42a is a receiving structure that can receive the positioning pin 45 from the first surface S1 side on which the image sensor 41 is arranged. The recess 42a is a substantially cylindrical cavity, and an inner flange portion 42b protruding inward of the recess 42a is formed on the side where the movable portion 48 of the positioning pin 45, which will be described later, is inserted so as to engage with the hook 48a. ing. The surface of the inner flange portion 42b that comes into contact with the hook 48a of the movable portion 48 is the second contact surface 42c. The surface of the recess 42a on the side where the rigid portion 49 of the positioning pin 45 is inserted is the first contact surface 42d.

The positioning pin 45 has a movable portion 48 and a rigid portion 49. The movable portion 48 has elasticity similar to the movable portion 23 of the first positioning pin 16 of the first embodiment, and when it is deformed toward the rigid portion 49, a restoring force acts in the opposite direction. A hook 48a is formed at the tip of the movable portion 48 to form a snap fit together with the recess 42a of the plate-shaped member 42. The recess 42a of the plate-shaped member 42 has a depth capable of accommodating at least the hook 48a on the inner side (−z direction) of the inner flange portion 42b. The rigid portion 49 of the positioning pin 45 is similar to the rigid portion 24 of the first positioning pin 16 of the first embodiment, and has higher rigidity than the movable portion 48.

Since it is configured as described above, in the fixed structure 40 according to the present embodiment, first, the positioning pin 45 is inserted into the recess 42a of the plate-shaped member 42. At this time, the movable portion 48 of the positioning pin 45 is pushed toward the rigid portion 49 and deformed. When the positioning pin 45 is inserted into the recess 42a, the movable portion 48 expands in the direction away from the rigid portion 49 and presses the inner side surface of the recess 42a. As a result, the plate-shaped member 42 is pushed and moved, and the first contact surface 42d of the recess 42a is brought into contact with the rigid portion 49 and is offset. As a result, the plate-shaped member 42 is positioned with respect to the positioning pin 45.

Further, since the hook 48a of the movable portion 48 comes into contact with the second contact surface 42c of the plate-shaped member 42, the hook 48a and the inner flange portion 42b of the plate-shaped member 42 are in a fitted state. Therefore, it is possible to prevent the plate-shaped member 42 from falling off from the positioning pin 45 when the plate-shaped member 42 is screwed to the mounting post 44 by the substrate fastening screw 47 after positioning. Further, the fixed structure 40 of the present embodiment is excellent in aesthetics because the tip portion of the positioning pin 45 cannot be seen from the outside. Further, in the present embodiment, since the positioning pin 45 does not penetrate to the second surface S2 of the plate-shaped member 42, a wider mounting area for mounting the element or the like on the second surface S2 can be secured.
