<実施の形態1>
図1は、本実施の形態1に係る撮像機器10の内部構成を示す斜視図であり、図2は、本実施の形態1に係る撮像機器10の外部構成を示す斜視図である。図1及び図2に示すように、撮像機器10は、基板1と、撮像部2と、ホルダー3と、シャーシ4と、筐体5とを備える。撮像機器10は車両に搭載され、車両の室内を撮像する。
<First embodiment>
Fig. 1 is a perspective view showing an internal configuration of an imaging device 10 according to the present embodiment 1, and Fig. 2 is a perspective view showing an external configuration of the imaging device 10 according to the present embodiment 1. 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.

図1及び図2に示すように、収容部である筐体5は、基板1と、撮像部2と、ホルダー3と、シャーシ4の一部とを収容する。なお、収容部は、直方体の筐体5でなくてもよい。1 and 2, the housing 5, which is the storage section, stores the board 1, the imaging section 2, the holder 3, and a part of the chassis 4. Note that the storage section does not have to be the housing 5 in the shape of a rectangular parallelepiped.

図1に示す基板1は、例えばプリント基板である。基板1の上面には撮像部2が搭載される。The substrate 1 shown in Fig. 1 is, for example, a printed circuit board. An imaging unit 2 is mounted on the upper surface of the substrate 1.

撮像部2は、車両の室内を撮像する。撮像部2は、レンズ2aと、イメージセンサー2bとを含む。イメージセンサー2bは、レンズ2aから離間して設けられており、レンズ2aからの光に基づいて画像を生成する。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.

ホルダー3は、撮像部2と基板1を介して接続されている。ホルダー3は、基板1に関して撮像部2と逆側に設けられる。図3及び図4に示すように、基板1の凸部がホルダー3の穴に嵌合され、ホルダー3の凸部が基板1の穴に嵌合された状態で、基板1とホルダー3とが、ねじ6aで互いに固定される。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 Figures 3 and 4, the convex portion of the substrate 1 is fitted into the hole of the holder 3, and with the convex portion of the holder 3 fitted into the hole of the substrate 1, the substrate 1 and the holder 3 are fixed to each other with screws 6a.

図3及び図4に示すように、ホルダー3は、本体3aと、突出板3bと、嵌合部である凸部3cと、ねじ穴3dとを有する。本体3aは、基板1の配線がショートしないように、基板1の一部から離間されている。突出板3bは、本体3aから撮像部2と逆側に突出する。図4に示す凸部3cは、突出板3bから突出板3bの面外方向に突出する。ねじ穴3dは、突出板3bの中央部分に設けられる。 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 an engaging 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 the imaging unit 2. The convex portion 3c shown in Figure 4 protrudes from the protruding plate 3b in a direction out of the plane of the protruding plate 3b. The screw hole 3d is provided in the central portion of the protruding plate 3b.

ホルダー3に固定されるシャーシ4は、複数のシャーシ4から選択的に使用される。図5は、複数のシャーシ4の構成を示す斜視図である。各シャーシ4は、車両の室内に取り付け可能となっている。本実施の形態1では、各シャーシ4は、図1に示す固定穴4eがねじ止めされることによって、車両の室内に取り付け可能となっている。ただし、各シャーシ4の車両の室内への取り付け構造は、これに限ったものではない。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 a plurality of chassis 4. Each chassis 4 can be attached to the interior of the vehicle. In this embodiment 1, each chassis 4 can be attached to the interior of the vehicle by screwing the fixing holes 4e shown in FIG. 1. However, the attachment structure of each chassis 4 to the interior of the vehicle is not limited to this.

各シャーシ4は、本体4aと、突出板4bと、被嵌合部である穴4cと、ねじ穴4dとを有する。突出板4bは、本体4aから突出する。穴4cは、突出板4bに設けられる。なお、穴4cは、貫通穴であってもよいし、非貫通穴であってもよいし、被嵌合部は、穴ではなく切り欠きであってもよい。ねじ穴4dは、突出板4bの中央部分に設けられる。Each chassis 4 has a main body 4a, a protruding plate 4b, a hole 4c which is a mating 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. Note that the hole 4c may be a through hole or a non-through hole, and the mating portion may be a notch rather than a hole. The screw hole 4d is provided in the center of the protruding plate 4b.

図4のホルダー3の突出板3bのねじ穴3dと、図5の一のシャーシ4の突出板4bのねじ穴4dとに、図1のねじ6bが通される。このため、ホルダー3の凸部3cを一のシャーシ4の穴4cに嵌合しなければ、ホルダー3と一のシャーシ4とは、ねじ6bを回転軸として回転可能となっている。一方、図6に示すように、ホルダー3の凸部3cを一のシャーシ4の穴4cに嵌合することによって、ホルダー3と一のシャーシ4の回転軸を中心とする回転は規制され、ホルダー3と一のシャーシ4との位置関係は固定される。 The screw 6b in Fig. 1 is passed through the screw hole 3d in the protruding plate 3b of the holder 3 in Fig. 4 and the screw hole 4d in 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.

図4及び図5に示すように、ホルダー3の凸部3cの数と、各シャーシ4の穴4cの数とは同じである。本実施の形態1では、ホルダー3の凸部3cの数は2つであり、各シャーシ4の穴4cの数は2つであるが、これらの数は2つに限ったものではない。また図5に示すように、複数のシャーシ4において、回転軸(つまりねじ穴4d)の周方向における穴4cの位置は互いに異なる。 As shown in Figures 4 and 5, the number of protrusions 3c on the holder 3 is the same as the number of holes 4c on each chassis 4. In this embodiment 1, the number of protrusions 3c on the holder 3 is two, and the number of holes 4c on each chassis 4 is two, but these numbers are not limited to two. Also, as shown in Figure 5, the positions of the holes 4c in the circumferential direction of the rotation axis (i.e., the screw holes 4d) are different from each other in multiple chassis 4.

<実施の形態1のまとめ>
本実施の形態1に係る撮像機器10では、ホルダー3の凸部3cの数と、各シャーシ4の穴4cの数とは同じである。したがって、ユーザは、ホルダー3の凸部3cを嵌合すべき、各シャーシ4の穴4cを容易に理解することができるので、穴4cへの凸部3cの嵌合を容易に行うことができる。
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.

また本実施の形態1に係る撮像機器10の製造方法では、図5のように複数のシャーシ4において、回転軸の周方向における穴4cの位置は互いに異なり、図6のようにホルダー3の凸部3cが、いずれかのシャーシ4の穴4cに嵌合される。このような構成によれば、ホルダー3に固定されるシャーシ4を変更することによって、固定部分においてホルダー3とシャーシ4とがなす角度を変更することができる。これにより図7及び図8に示すように、ホルダー3に固定されるシャーシ4を適切に選択することで、シャーシ4以外の部分を変更しなくても、撮像部2の撮像方向を車両の運転者などの乗員に向けることができる。これにより、撮像機器10の低コスト化が期待できる。また、撮像機器10を適用するDMS(Driver Monitoring System)において、乗員から適切な画像を撮像することができる。 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 occupants without changing any part other than the chassis 4. This is expected to reduce the cost of the imaging device 10. In addition, in a DMS (Driver Monitoring System) to which the imaging device 10 is applied, an appropriate image can be captured from the occupant.

<変形例>
以上の説明では、図5に示したように、複数のシャーシ4のそれぞれにおいて、本体4aと突出板4bとがなす角度は概ね垂直であったが、これに限ったものではない。例えば、複数のシャーシ4において、本体4aと突出板4bとがなす角度が互いに異なってもよい。このような構成によれば、ホルダー3に固定されるシャーシ4を適切に選択することで、上記回転軸と異なる回転軸に沿った、ホルダー3とシャーシ4とがなす角度を変更することができる。
<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 to be 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.

なお、実施の形態の内容を適宜、変形、省略することが可能である。 The contents of the embodiments may be modified or omitted as appropriate.

上記した説明は、すべての局面において、例示であって、限定的なものではない。例示されていない無数の変形例が、想定され得るものと解される。The above description is illustrative in all respects and is not limiting. It is understood that countless variations not illustrated can be envisioned.
