Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In all the drawings, the same components are denoted by the same reference numerals, and the description thereof will be omitted as appropriate.

[0010] FIG. 1 is a perspective view of the sensor device 10 according to the embodiment from above and behind. FIG. 2 is a perspective view of the sensor device 10 shown in FIG. 1 from the front. FIG. 3 is a bottom view of the sensor device 10 shown in FIG. 1. FIG. 4 is a rear view of the sensor device 10 shown in FIG. 1. FIG. 5 is an exploded perspective view of the sensor device 10 shown in FIG. 1. FIG. 6 is a view in which the second part 120 of the housing 100 and the control unit 320 of the electronic device 300 are removed from FIG. 5. FIG. 7 is a view in which the optical device 200, the power supply unit 310 of the electronic device 300, and the control wiring 326 are removed from FIG. 6.

[0011] In FIGS. 1 to 7, the first direction X is the front-rear direction of the sensor device 10. The positive direction of the first direction X (the direction indicated by the arrow indicating the first direction X) is the front direction of the sensor device 10. The negative direction of the first direction X (the direction opposite to the direction indicated by the arrow indicating the first direction X) is the rear direction of the sensor device 10. The second direction Y intersects the first direction X, specifically, is orthogonal to it. The second direction Y is the left-right direction of the sensor device 10. The positive direction of the second direction Y (the direction indicated by the arrow indicating the second direction Y) is the right direction when viewed from the front (the positive direction of the first direction X) of the sensor device 10. The negative direction of the second direction Y (the direction opposite to the direction indicated by the arrow indicating the second direction Y) is the left direction when viewed from the front (the positive direction of the first direction X) of the sensor device 10. The third direction Z intersects both the first direction X and the second direction Y, specifically, is orthogonal to them. The third direction Z is the up-down direction of the sensor device 10. The positive direction of the third direction Z (the direction indicated by the arrow indicating the third direction Z) is the up direction of the sensor device 10. The negative direction of the third direction Z (the direction opposite to the direction indicated by the arrow indicating the third direction Z) is the down direction of the sensor device 10.

[0012] The sensor device 10 includes a housing 100, an optical device 200, an electronic device 300, a power supply terminal 314, and a control terminal 324.

[0013] The housing 100 has a first part 110 (lower part) and a second part 120 (upper part). In the present embodiment, the first part 110 functions as a housing member that opens the space inside the first part 110 (housing 100) upward (the positive direction of the third direction Z) and rearward (the negative direction of the first direction X) of the housing 100. On the other hand, the second part 120 functions as a cover member that closes the space opened by the first part 110. The second part 120 can be fixed to the first part 110 by a fixture such as a screw.

[0014] The first part 110 includes a first surface 112 (bottom surface), a first side surface 114 (front side surface), a second side surface 116 (right side surface), and a third side surface 118 (left side surface). The first side surface 114 is directed laterally (forward, that is, the positive direction of the first direction X) with respect to the direction in which the first surface 112 is directed (downward, that is, the negative direction of the third direction Z). A window portion 130 is provided on the first side surface 114. The second side surface 116 is directed laterally (rightward, that is, the positive direction of the second direction Y) with respect to both the direction in which the first surface 112 is directed (downward, that is, the negative direction of the third direction Z) and the direction in which the first side surface 114 is directed (forward, that is, the positive direction of the first direction X). The third side surface 118 is directed to the opposite side (leftward, that is, the negative direction of the second direction Y) with respect to the direction in which the second side surface 116 is directed (rightward, that is, the positive direction of the second direction Y).

[0015] The second part 120 includes a second surface 122 (top surface), a fourth side surface 124 (rear side surface), a fifth side surface 126 (right side surface), and a sixth side surface 128 (left side surface). The second surface 122 is oriented in the direction opposite to the direction in which the first surface 112 is oriented (downward, i.e., the negative direction of the third direction Z) (upward, i.e., the positive direction of the third direction Z). The fourth side surface 124 is oriented laterally (rearward, i.e., the negative direction of the first direction X) with respect to the direction in which the second surface 122 is oriented (downward, i.e., the negative direction of the third direction Z). The fifth side surface 126 is oriented in the same direction as the direction in which the second side surface 116 is oriented (rightward, i.e., the positive direction of the second direction Y). That is, the fifth side surface 126 is oriented laterally (rightward, i.e., the positive direction of the second direction Y) with respect to both the direction in which the second surface 122 is oriented (upward, i.e., the positive direction of the third direction Z) and the direction in which the fourth side surface 124 is oriented (rearward, i.e., the negative direction of the first direction X). The sixth side surface 128 is oriented in the same direction as the direction in which the third side surface 118 is oriented (leftward, i.e., the negative direction of the second direction Y). That is, the sixth side surface 128 is oriented in the direction opposite to the direction in which the fifth side surface 126 is oriented (rightward, i.e., the positive direction of the second direction Y) (leftward, i.e., the negative direction of the second direction Y).

[0016] The optical device 200 is housed in the housing 100. The optical device 200 is located in front of the space within the housing 100 (the positive direction of the first direction X) rather than behind the space within the housing 100 (the negative direction of the first direction X). The optical device 200 is attached to the first part 110 of the housing 100. However, the optical device 200 may be attached to the second part 120 of the housing 100. The optical device 200 scans an object (not shown in FIGS. 1 to 7) existing outside the sensor device 10 by electromagnetic waves passing through the window portion 130.

[0017] The first part 110 and the second part 120 of the housing 100 are separable obliquely from the side of the first side surface 114 (window portion 130) (front side, i.e., the positive direction side of the first direction X) to the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear side, i.e., the negative direction side of the first direction X) with respect to the first surface 112 or the second surface 122 of the housing 100 from the side of the second surface 122 of the housing 100 (upper side, i.e., the positive direction side of the third direction Z) to the side of the first surface 112 (lower side, i.e., the negative direction side of the third direction Z). In this case, for example, compared with the case where the first part 110 and the second part 120 of the housing 100 are separable along parallel to the first surface 112 or the second surface 122 of the housing 100, the space inside the housing 100 is greatly exposed toward the rear (negative direction of the first direction X) of the housing 100 when the second part 120 is removed from the first part 110. Therefore, it is easy to attach the optical device 200 from the rear (negative direction of the first direction X) of the housing 100 to the space inside the housing 100. For this reason, the accommodation of the optical device 200 in the housing 100 is simplified.

[0018] Furthermore, the boundary between the first part 110 and the second part 120 of the housing 100 is formed along a plane (a plane that is oblique with respect to the first direction X or the third direction Z when viewed from the positive direction of the second direction Y). Also, the housing 100 includes a sealing member 140 (e.g., rubber) provided along the above-mentioned plane between the first part 110 and the second part 120 of the housing 100. In this case, compared with the case where the boundary between the first part 110 and the second part 120 of the housing 100 is not along a plane, the sealing member 140 can be stably arranged between the first part 110 and the second part 120 of the housing 100, and the waterproofness of the housing 100 can be improved. However, the boundary between the first part 110 and the second part 120 of the housing 100 does not necessarily have to be formed along a plane.

[0019] The electronic device 300 has a power supply unit 310 and a control unit 320. The power supply unit 310 supplies power used to drive the optical device 200 to the optical device 200. The control unit 320 supplies a control signal of the optical device 200 to the optical device 200. In the present embodiment, the power supply unit 310 and the control unit 320 are attached to the first portion 110 of the housing 100. However, the power supply unit 310 and the control unit 320 may be attached to the second portion 120 of the housing 100.

[0020] The power supply unit 310 is located in front of the space inside the housing 100 (in the positive direction of the first direction X) rather than behind the space inside the housing 100 (in the negative direction of the first direction X). Also, the power supply unit 310 is aligned with the optical device 200 in a direction (the second direction Y) intersecting the direction (the first direction X) from the first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) to the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, i.e., the negative direction of the first direction X). The control unit 320 is aligned with the optical device 200 and the power supply unit 310 in the direction (the first direction X) from the first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) to the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, i.e., the negative direction of the first direction X). Also, the control unit 320 is located behind the space inside the housing 100 (in the negative direction of the first direction X) rather than in front of the space inside the housing 100 (in the positive direction of the first direction X). Generally, the space for arranging the control unit 320 (for example, the control board 322 whose details will be described later) needs to be larger than the space for arranging the power supply unit 310 (for example, the power supply board 312 whose details will be described later). According to the present embodiment, by arranging the optical device 200 and the power supply unit 310 along the second direction Y, a larger space for arranging the control unit 320 can be secured behind the optical device 200 and the power supply unit 310 (in the negative direction of the first direction X). Therefore, the optical device 200, the power supply unit 310, and the control unit 320 can be efficiently arranged in the space inside the housing 100.

[0021] The layouts of the optical device 200 and the electronic device 300 are not limited to the layouts according to this embodiment. For example, at least a part of the electronic device 300 may be arranged side by side with the optical device 200 from the side of the first side surface 114 (window portion 130) (front, that is, the positive direction of the first direction X) toward the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, that is, the negative direction of the first direction X). For example, both the power supply unit 310 and the control unit 320 may be arranged behind the optical device 200 (the negative direction of the first direction X), or the power supply unit 310 and the control unit 320 may be arranged in the regions where the control unit 320 and the power supply unit 310 are arranged in this embodiment, respectively.

[0022] The power supply unit 310 includes a plurality (three) of power supply substrates 312. Each power supply substrate 312 has a thickness along the direction (the first direction X) from the side of the first side surface 114 (window portion 130) (front, that is, the positive direction of the first direction X) toward the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, that is, the negative direction of the first direction X). Further, the plurality of power supply substrates 312 are arranged side by side along the direction (the first direction X) from the side of the first side surface 114 (window portion 130) (front, that is, the positive direction of the first direction X) toward the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, that is, the negative direction of the first direction X). In this case, each power supply substrate 312 can be efficiently arranged in the space within the housing 100 as compared with the case where each power supply substrate 312 has a thickness along a direction different from the first direction X (for example, the third direction Z). The number of power supply substrates 312 included in the power supply unit 310 does not have to be three, and may be only one or two, or may be four or more. Also, each power supply substrate 312 may have a thickness along a direction different from the first direction X (for example, the third direction Z).

[0023] The power supply board 312 is supported by the first support member 332. The first support member 332 is fixed to the inner surface of the housing 100 (the first part 110) on the front side (the positive direction side of the first direction X) of the space inside the housing 100. Fixing tools such as screws that penetrate the power supply board 312 from the rear (the negative direction of the first direction X) to the front (the positive direction of the first direction X) of the housing 100 can be attached to the first support member 332. Therefore, the power supply board 312 can be fixed to the first support member 332 by the fixing tool.

[0024] The control unit 320 includes a plurality (two) of control boards 322. Each control board 322 has a thickness along the direction (the first direction X) from the first side surface 114 (window portion 130) side (front, that is, the positive direction of the first direction X) to the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, that is, the negative direction of the first direction X). Further, the plurality of control boards 322 are arranged along the direction (the first direction X) from the first side surface 114 (window portion 130) side (front, that is, the positive direction of the first direction X) to the opposite side of the first side surface 114 (window portion 130) (the fourth side surface 124 side) (rear, that is, the negative direction of the first direction X). In this case, each control board 322 can be efficiently arranged in the space inside the housing 100 as compared with the case where each control board 322 has a thickness along a direction different from the first direction X (for example, the third direction Z). The number of control boards 322 included in the control unit 320 does not have to be two, and may be only one, or may be three or more. Also, each control board 322 may have a thickness along a direction different from the first direction X (for example, the third direction Z).

[0025] The control board 322 is supported by the second support member 334. The second support member 334 is fixed to the inner bottom surface of the housing 100 (the first part 110) on the lower side (the negative direction side of the third direction Z) of the space inside the housing 100. Fixing tools such as screws that penetrate the control board 322 from the rear (the negative direction of the first direction X) to the front (the positive direction of the first direction X) of the housing 100 can be attached to the second support member 334. Therefore, the control board 322 can be fixed to the second support member 334 by the fixing tool.

[0026] The power supply terminal 314 is provided on the opposite side of the power supply unit 310 with respect to the control unit 320 (on the negative side in the first direction X with respect to the control unit 320) in the housing 100 (the first part 110). In other words, when viewed from the third direction Z, the power supply terminal 314 is located within a region aligned with the power supply unit 310 in the first direction X. In this case, for example, compared with the case where the power supply unit 310 and the power supply terminal 314 are displaced from each other in the second direction Y, the distance between the power supply unit 310 and the power supply terminal 314 can be shortened, and the total length of the power supply wiring 316 described later can be shortened. However, the arrangement of the power supply terminal 314 is not limited to the arrangement according to this embodiment. For example, the power supply terminal 314 may be arranged displaced from the power supply unit 310 in the second direction Y. In this case, the power supply terminal 314 may be located, for example, at the center of the first part 110 of the housing 100 in the second direction Y, or may be located displaced in the positive direction of the second direction Y from the center of the first part 110 of the housing 100 in the second direction Y.

[0027] The control terminal 324 is adjacent to the power supply terminal 314 in the second direction Y. In this embodiment, the control terminal 324 is located on the positive side in the second direction Y with respect to the power supply terminal 314. However, the layout of the power supply terminal 314 and the control terminal 324 is not limited to the layout according to this embodiment. For example, the control terminal 324 may be located on the negative side in the second direction Y with respect to the power supply terminal 314.

[0028] The power supply terminal 314 and the control terminal 324 are electrically connected to the power supply unit 310 and the control unit 320 via a power supply wiring 316 and a control wiring 326, respectively. Further, the control unit 320 (control board 322) has a notch 322a. The power supply wiring 316 passes through the notch 322a of the control unit 320. For example, when the notch 322a is not provided (for example, when the control board 322 has a rectangular shape), in order to connect the power supply wiring 316 to the power supply unit 310 and the power supply terminal 314, it is necessary to detour the power supply wiring 316 with respect to the power supply unit 310, or to move the power supply unit 310 in the second direction Y or the third direction Z so that a space for passing the power supply wiring 316 is formed. When the power supply wiring 316 is detoured with respect to the power supply unit 310, the total length of the power supply wiring 316 can become long. Further, when the power supply unit 310 is moved in the second direction Y or the third direction Z, the space for arranging the power supply unit 310 can become large. On the other hand, in the present embodiment, it is not necessary to detour the power supply wiring 316 with respect to the power supply unit 310, and the total length of the power supply wiring 316 can be shortened. Further, in the present embodiment, it is not necessary to move the power supply unit 310 in the second direction Y or the third direction Z, and the space for arranging the power supply unit 310 can be reduced. However, the control board 322 may not have the notch 322a, and may have, for example, a rectangular shape.

[0029] FIG. 8 is a diagram for explaining an example of the operation of the optical device 200 accommodated in the housing 100 described with reference to FIGS. 1 to 7. The first direction X and the second direction Y in FIG. 8 are the same as the first direction X and the second direction Y in FIGS. 1 to 7, respectively.

[0030] An example of the operation of the optical device 200 will be described with reference to FIG. 8 while referring to FIGS. 1 to 7.

[0031] The optical device 200 includes a transmission unit 210, a movable reflection unit 220, a reception unit 230, and a beam splitter 240. In FIG. 8, the transmission unit 210, the movable reflection unit 220, the reception unit 230, and the beam splitter 240 are schematically located in a plane parallel to both the first direction X and the second direction Y. However, in an actual layout, the transmission unit 210, the movable reflection unit 220, the reception unit 230, and the beam splitter 240 may not be located in a plane parallel to both the first direction X and the second direction Y, or may be located in a plane parallel to both the first direction X and the second direction Y.

[0032] In FIG. 8, the electromagnetic waves propagating through the transmission unit 210, the movable reflection unit 220, the reception unit 230, and the beam splitter 240 are indicated by dashed lines.

[0033] The transmission unit 210 transmits electromagnetic waves. In one example, the electromagnetic waves transmitted by the transmission unit 210 are light, specifically, infrared rays. However, the electromagnetic waves transmitted by the transmission unit 210 may be light with a wavelength different from that of infrared rays (for example, visible light or ultraviolet light), or may be electromagnetic waves with a wavelength different from that of light waves (for example, radio waves). In one example, the transmission unit 210 transmits a pulse wave. However, the transmission unit 210 may transmit a continuous wave (CW). In one example, the transmission unit 210 is an element (for example, a laser diode (LD)) capable of converting electrical energy (for example, current) into electromagnetic waves.

[0034] The electromagnetic waves transmitted from the transmission unit 210 pass through the beam splitter 240 and are incident on the movable reflection unit 220, and are reflected by the movable reflection unit 220. The movable reflection unit 220 is, for example, a MEMS (Micro Electro Mechanical Systems) mirror.

[0035] The electromagnetic wave reflected by the movable reflection part 220 passes through the window part 130 and is emitted outward from the sensor device 10. The electromagnetic wave emitted outward from the sensor device 10 is incident on an object (not shown in FIG. 8) located outside the sensor device 10 and is reflected by the object. The electromagnetic wave reflected or scattered by the object passes through the window part 130 and is incident on the movable reflection part 220. The electromagnetic wave incident on the movable reflection part 220 passes through the reflection by the movable reflection part 220 and the reflection by the beam splitter 240 in sequence and is incident on the receiving part 230. The receiving part 230 receives the electromagnetic wave incident on the receiving part 230. In one example, the receiving part 230 is an element (for example, an avalanche photodiode (APD)) that can convert an electromagnetic wave into electrical energy (for example, an electric current).

[0036] The sensor device 10 is, for example, LiDAR (Light Detection And Ranging). In one example, the sensor device 10 measures the distance between the sensor device 10 and an object located outside the sensor device 10 based on ToF (Time of Flight). In this example, the sensor device 10 calculates the above distance based on the difference between the time when an electromagnetic wave is transmitted from the sensor device 10 (for example, the time when the electromagnetic wave is transmitted from the transmitting part 210) and the time when the electromagnetic wave transmitted from the sensor device 10 and reflected by an object located outside the sensor device 10 is received by the sensor device 10 (for example, the time when the electromagnetic wave is received by the receiving part 230).

[0037] The optical device 200 has a viewing field F that extends along the horizontal direction (the direction along a plane parallel to both the first direction X and the second direction Y). Specifically, the movable reflecting portion 220 is swingable around the axis 222. The axis 222 extends along the third direction Z. The viewing field F of the optical device 200 is determined according to the maximum swing angle of the movable reflecting portion 220. When the swing angle of the movable reflecting portion 220 is 0 degrees, the electromagnetic wave transmitted from the transmitting portion 210 and reflected by the movable reflecting portion 220 passes through the straight line L. When viewed from the positive direction of the third direction Z, when the movable reflecting portion 220 swings counterclockwise by the maximum swing angle of the optical device 200, the electromagnetic wave transmitted from the transmitting portion 210 and reflected by the movable reflecting portion 220 passes through one end of the viewing field F (the left end of the viewing field F in FIG. 8). When viewed from the positive direction of the third direction Z, when the movable reflecting portion 220 swings clockwise by the maximum swing angle of the optical device 200, the electromagnetic wave transmitted from the transmitting portion 210 and reflected by the movable reflecting portion 220 passes through the other end on the opposite side of the above-mentioned one end of the viewing field F (the right end of the viewing field F in FIG. 8).

[0038] The optical device 200 may have a viewing field that extends not only along the horizontal direction (the direction along a plane parallel to both the first direction X and the second direction Y), but also along a direction different from the horizontal direction (for example, the vertical direction (for example, the direction along a plane parallel to both the first direction X and the third direction Z)). Alternatively, instead of the horizontal direction (the direction along a plane parallel to both the first direction X and the second direction Y), the optical device 200 may have a viewing field that extends along a direction different from the horizontal direction (for example, the vertical direction (for example, the direction along a plane parallel to both the first direction X and the third direction Z)). That is, the optical device 200 may have a predetermined viewing field that extends along at least one direction.

[0039] For example, when the optical device 200 has a viewing field that extends along the vertical direction (the direction along a plane parallel to both the first direction X and the third direction Z), the movable reflecting portion 220 is swingable around an axis that extends along the second direction Y. That is, according to the spread of the viewing field of the optical device 200, the movable reflecting portion 220 is swingable around at least one axis.

[0040] As shown in FIGS. 3 and 4, a first shaped portion 152 and a second shaped portion 154 are provided on the outer surface of the housing 100. The first shaped portion 152 and the second shaped portion 154 are engageable with other shaped portions located outside the housing 100 (details of the relationship between the first shaped portion 152 or the second shaped portion 154 and other shaped portions located outside the housing 100 will be described later). The visual field F can be positioned (fixed) by the first shaped portion 152 and the second shaped portion 154. Specifically, when viewed from the third direction Z (i.e., the direction perpendicular to the direction in which the visual field F spreads, or the extending direction of the axis 222), the first shaped portion 152 and the second shaped portion 154 are aligned on the same straight line as the straight line L (i.e., a virtual straight line passing through the center of the visual field F of the optical device 200 when viewed from the third direction Z, or a virtual straight line through which the electromagnetic wave reflected by the movable reflecting portion 220 at a swing angle of 0 degrees passes). Therefore, by engaging the first shaped portion 152 and the second shaped portion 154 (i.e., the engaging portions) with other shaped portions (i.e., the engaging portions) located outside the housing 100, the housing 100 can be prevented from rotating around the third direction Z, and the visual field F (i.e., the straight line L) is positioned (fixed). Further, since the first shaped portion 152 and the second shaped portion 154 are aligned on the same straight line as the straight line L when viewed from the third direction Z, the user of the sensor device 10 can recognize the position of the center of the visual field F of the optical device 200 using the first shaped portion 152 and the second shaped portion 154 as landmarks.

[0041] The first shaped portion 152 and the second shaped portion 154 may not be on the same straight line as the straight line L and may be shifted from the straight line L in the second direction Y when viewed from the third direction Z. That is, when viewed from the third direction Z, the first shaped portion 152 and the second shaped portion 154 may be aligned along a direction parallel to the straight line L. Even in this case, by engaging the first shaped portion 152 and the second shaped portion 154 with other shaped portions located outside the housing 100, the housing 100 can be prevented from rotating around the third direction Z, and the visual field F is positioned.

[0042] Each of the first shaped portion 152 and the second shaped portion 154 is a concave portion. Therefore, as compared with the case where each of the first shaped portion 152 and the second shaped portion 154 is a convex portion, the possibility that the first shaped portion 152 and the second shaped portion 154 come into contact with and interfere with elements outside the housing 100 can be reduced. However, each of the first shaped portion 152 and the second shaped portion 154 may be a convex portion. Even in this case, the first shaped portion 152 and the second shaped portion 154 can be engaged with other shaped portions located outside the housing 100. Also, one of the first shaped portion 152 and the second shaped portion 154 may be a concave portion and the other may be a convex portion. That is, the first shaped portion 152 and the second shaped portion 154 can be made into concave or convex portions independently of each other.

[0043] Another shaped portion located outside the housing 100 and engaged with the first shaped portion 152 and the second shaped portion 154 can be made into a convex or concave portion according to whether the first shaped portion 152 and the second shaped portion 154 are concave or convex portions. For example, when the first shaped portion 152 (the second shaped portion 154) is a concave portion (e.g., a positioning hole), another shaped portion located outside the sensor device 10 can be made into a convex portion (e.g., a positioning pin). On the other hand, when the first shaped portion 152 (the second shaped portion 154) is a convex portion (e.g., a positioning pin), another shaped portion located outside the sensor device 10 can be made into a concave portion (e.g., a positioning hole).

[0044] The first shaped portion 152 and the second shaped portion 154 are provided on the bottom surface (the first surface 112) of the housing 100 (the first portion 110). In this case, the field of view F can be positioned simply by placing the housing 100 on a placement surface provided with other shaped portions that engage with the first shaped portion 152 and the second shaped portion 154. Therefore, positioning of the field of view F is facilitated. However, the first shaped portion 152 and the second shaped portion 154 may be provided on a surface different from the bottom surface (the first surface 112) of the housing 100 (the first portion 110). Also, the first shaped portion 152 and the second shaped portion 154 may be provided on a common surface of the housing 100, such as both the first shaped portion 152 and the second shaped portion 154 being provided on the first surface 112 of the housing 100 (the first portion 110) as in the present embodiment. Alternatively, the first shaped portion 152 and the second shaped portion 154 may be provided on different surfaces from each other, for example, the first shaped portion 152 being provided on the first surface 112 of the housing 100 (the first portion 110) and the second shaped portion 154 being provided on the second surface 122 of the housing 100 (the second portion 120).

[0045] The first shaped portion 152 is located on the rear side (the negative direction side of the first direction X) of the housing 100 with respect to the second shaped portion 154. Also, the first shaped portion 152 is located on the rear side (the negative direction of the first direction X) of the housing 100 rather than on the front side (the positive direction of the first direction X) of the housing 100. Further, the first shaped portion 152 (the concave portion) is provided at a portion where the bottom surface (the first surface 112) of the housing 100 (the first portion 110) and the outer surface of the housing 100 (the outer surface where the power terminals 314 and the control terminals 324 are provided) intersect. The second shaped portion 154 is located on the front side (the positive direction side of the first direction X) of the housing 100 with respect to the first shaped portion 152. Also, the second shaped portion 154 is located on the front side (the positive direction of the first direction X) of the housing 100 rather than on the rear side (the negative direction of the first direction X) of the housing 100. Further, the second shaped portion 154 is located so as to be shifted rearward (the negative direction of the first direction X) from the front side surface (the first side surface 114) of the housing 100 (the first portion 110). However, the second shaped portion 154 (the concave portion) may be provided at a portion where the bottom surface (the first surface 112) of the housing 100 (the first portion 110) and the outer surface (the first side surface 114) of the housing 100 intersect, in the same manner as the first shaped portion 152. That is, at least one of the first shaped portion 152 and the second shaped portion 154 may be provided at a portion where the bottom surface (for example, the first surface 112) of the housing 100 and the outer surface (for example, the first side surface 114, or the surface where the power terminals 314 and the control terminals 324 are provided) of the housing 100 intersect.

[0046] In the present embodiment, the first shaped portion 152 and the second shaped portion 154 position the visual field (visual field F) when viewed from the third direction Z. However, even for a visual field when viewed from a direction different from the third direction Z, for example, the second direction Y, the first shaped portion 152 and the second shaped portion 154 can be used in the same manner as the method described in the present embodiment to perform positioning.

[0047] FIG. 9 is a diagram showing a modified example of FIG. 3.

[0048] The first shaped portion 152 (second shaped portion 154) (e.g., a concave portion or a convex portion) may extend along the first direction X. In the example shown in FIG. 9, the length of the first shaped portion 152 (second shaped portion 154) in the first direction X is longer than the width of the first shaped portion 152 (second shaped portion 154) in the second direction Y. Even in this case, by positioning the first shaped portion 152 (second shaped portion 154) outside the housing 100 and engaging it with another shaped portion that is long in one direction, the housing 100 can be prevented from rotating around the third direction Z, and the visual field F can be positioned.

[0049] As described above, the embodiments and modifications have been described with reference to the drawings. These are examples of the present invention, and various configurations other than those described above can also be adopted.

[0050] For example, in the present embodiment, the first portion 110 and the second portion 120 of the housing 100 are the lower portion and the upper portion of the housing 100, respectively. However, the first portion 110 and the second portion 120 of the housing 100 may be the upper portion and the lower portion of the housing 100, respectively, for example.

[0051] In the present embodiment, the housing 100 houses both the optical device 200 and the electronic device 300. However, the housing 100 may house only the optical device 200, and the electronic device 300 may be provided outside the housing 100.

[0052] In the present embodiment, the first portion 110 and the second portion 120 of the housing 100 are separable obliquely along the first surface 112 or the second surface 122 of the housing 100. However, the first portion 110 and the second portion 120 of the housing 100 may be separable parallel to the first surface 112 or the second surface 122 of the housing 100.
