[0010] <Embodiment 1> Fig. 1 is a perspective view showing an internal configuration of an imaging device 10 according to the first embodiment, and Fig. 2 is a perspective view showing an external configuration of the imaging device 10 according to the first embodiment. As shown in Fig. 1 and Fig. 2, the imaging device 10 includes a board 1, an imaging unit 2, a holder 3, a chassis 4, and a housing 5. The imaging device 10 is mounted on a vehicle and captures an image of the interior of the vehicle.

[0011] 1 and 2, the housing 5 serving as the housing section houses the board 1, the imaging section 2, the holder 3, and a part of the chassis 4. Note that the housing section does not have to be the housing 5 having a rectangular parallelepiped shape.

[0012] 1 is a printed circuit board, for example. An imaging unit 2 is mounted on the upper surface of the board 1.

[0013] The imaging unit 2 captures an image of the interior of the vehicle. The imaging unit 2 includes a lens 2a and an image sensor 2b. The image sensor 2b is provided at a distance from the lens 2a and generates an image based on the light from the lens 2a.

[0014] The holder 3 is connected to the imaging unit 2 via the substrate 1. The holder 3 is provided on the opposite side of the substrate 1 to the imaging unit 2. As shown in Fig. 3 and Fig. 4, the convex portion of the substrate 1 is fitted into the hole of the holder 3, and in a state in which the convex portion of the holder 3 is fitted into the hole of the substrate 1, the substrate 1 and the holder 3 are fixed to each other with screws 6a.

[0015] As shown in Figures 3 and 4, the holder 3 has a main body 3a, a protruding plate 3b, a convex portion 3c which is a fitting portion, and a screw hole 3d. The main body 3a is separated from a part of the board 1 so as to prevent shorting of the wiring of the board 1. The protruding plate 3b protrudes from the main body 3a on the side opposite to the imaging unit 2. The convex portion 3c shown in Figure 4 protrudes from the protruding plate 3b in the out-of-plane direction of the protruding plate 3b. The screw hole 3d is provided in the center of the protruding plate 3b.

[0016] The chassis 4 fixed to the holder 3 is selectively used from a plurality of chassis 4. FIG. 5 is a perspective view showing the configuration of the plurality of chassis 4. Each chassis 4 can be attached to the interior of the vehicle. In the present embodiment 1, each chassis 4 can be attached to the interior of the vehicle by screwing into the fixing holes 4e shown in FIG. 1. However, the structure for attaching each chassis 4 to the interior of the vehicle is not limited to this.

[0017] Each chassis 4 has a main body 4a, a protruding plate 4b, a hole 4c as a fitting portion, and a screw hole 4d. The protruding plate 4b protrudes from the main body 4a. The hole 4c is provided in the protruding plate 4b. The hole 4c may be a through hole or a non-through hole, and the fitting portion may be a notch instead of a hole. The screw hole 4d is provided in the center of the protruding plate 4b.

[0018] The screw 6b in Fig. 1 is passed through the screw hole 3d of the protruding plate 3b of the holder 3 in Fig. 4 and the screw hole 4d of the protruding plate 4b of the first chassis 4 in Fig. 5. Therefore, unless the protruding portion 3c of the holder 3 is fitted into the hole 4c of the first chassis 4, the holder 3 and the first chassis 4 can rotate around the screw 6b as a rotation axis. On the other hand, as shown in Fig. 6, by fitting the protruding portion 3c of the holder 3 into the hole 4c of the first chassis 4, the rotation of the holder 3 and the first chassis 4 around the rotation axis is restricted, and the positional relationship between the holder 3 and the first chassis 4 is fixed.

[0019] 4 and 5, the number of protrusions 3c of the holder 3 is the same as the number of holes 4c of each chassis 4. In the present embodiment 1, the number of protrusions 3c of the holder 3 is two, and the number of holes 4c of each chassis 4 is two, but these numbers are not limited to two. Also, as shown in FIG. 5, the positions of the holes 4c in the circumferential direction of the rotation axis (i.e., the screw holes 4d) are different from one another in the multiple chassis 4.

[0020] <Summary of the first embodiment> In the imaging device 10 according to the first embodiment, the number of the protrusions 3c of the holder 3 is the same as the number of the holes 4c of each chassis 4. Therefore, the user can easily understand the holes 4c of each chassis 4 into which the protrusions 3c of the holder 3 should be fitted, and can easily fit the protrusions 3c into the holes 4c.

[0021] In the manufacturing method of the imaging device 10 according to the first embodiment, the positions of the holes 4c in the circumferential direction of the rotation axis are different in the multiple chassis 4 as shown in FIG. 5, and the convex portion 3c of the holder 3 is fitted into the hole 4c of one of the chassis 4 as shown in FIG. 6. According to this configuration, by changing the chassis 4 fixed to the holder 3, the angle formed by the holder 3 and the chassis 4 at the fixed portion can be changed. As a result, as shown in FIG. 7 and FIG. 8, by appropriately selecting the chassis 4 fixed to the holder 3, the imaging direction of the imaging unit 2 can be directed toward the vehicle driver or other passengers without changing any part other than the chassis 4. This is expected to reduce the cost of the imaging device 10. Also, in a DMS (Driver Monitoring System) to which the imaging device 10 is applied, an appropriate image can be captured from the passenger.

[0022] <Modification> In the above description, as shown in Fig. 5, the angle between the main body 4a and the protruding plate 4b in each of the multiple chassis 4 is approximately perpendicular, but this is not limited to this. For example, the angles between the main body 4a and the protruding plate 4b in the multiple chassis 4 may be different from each other. With this configuration, by appropriately selecting the chassis 4 fixed to the holder 3, it is possible to change the angle between the holder 3 and the chassis 4 along a rotation axis different from the above rotation axis.

[0023] The contents of the embodiments can be modified or omitted as appropriate.

[0024] The above description is illustrative in all respects and is not restrictive. It is understood that countless variations not illustrated can be envisioned. [Explanation of symbols]
