[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.

[0011] 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 opposite direction 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 with the first direction X, specifically, is perpendicular 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 as viewed from the front of the sensor device 10 (the positive direction of the first direction X). The negative direction of the second direction Y (the opposite direction to the direction indicated by the arrow indicating the second direction Y) is the left direction as viewed from the front of the sensor device 10 (the positive direction of the first direction X). The third direction Z intersects with both the first direction X and the second direction Y, specifically, is perpendicular 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 upward direction of the sensor device 10. The negative direction of the third direction Z (the opposite direction to the direction indicated by the arrow indicating the third direction Z) is the downward 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 portion 110 (lower portion) and a second portion 120 (upper portion). In this embodiment, the first portion 110 functions as a housing member that opens the space inside the first portion 110 (housing 100) toward the upper side of the housing 100 (the positive direction of the third direction Z) and toward the rear side of the housing 100 (the negative direction of the first direction X). On the other hand, the second portion 120 functions as a cover member that closes the space opened by the first portion 110. The second portion 120 can be fixed to the first portion 110 by a fastener such as a screw.

[0014] The first portion 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 oriented laterally (forward, i.e., in the positive direction of the first direction X) with respect to the direction in which the first surface 112 is oriented (downward, i.e., in the negative direction of the third direction Z). The first side surface 114 is provided with a window portion 130. The second side surface 116 is oriented laterally (right side, i.e., in the positive direction of the second direction Y) with respect to both the direction in which the first surface 112 is oriented (downward, i.e., in the negative direction of the third direction Z) and the direction in which the first side surface 114 is oriented (forward, i.e., in the positive direction of the first direction X). The third side surface 118 faces the opposite side (left side, ie, the negative direction in the second direction Y) to the direction in which the second side surface 116 faces (right side, ie, the positive direction in the second direction Y).

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

[0016] The optical device 200 is accommodated in the housing 100. The optical device 200 is located in the front of the space in the housing 100 (in the positive direction of the first direction X) rather than in the rear of the space in the housing 100 (in 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 second surface 122 side (upper side, i.e., the positive side of the third direction Z) of the housing 100 toward the first surface 112 side (lower side, i.e., the negative side of the third direction Z) with respect to the first surface 112 or second surface 122 of the housing 100 as they move from the first side surface 114 (window portion 130) side (front side, i.e., the positive side of the first direction X) toward the opposite side of the first side surface 114 (window portion 130) (fourth side surface 124 side) (rear side, i.e., the negative side of the first direction X). In this case, for example, compared to a case where the first part 110 and the second part 120 of the housing 100 are separable along a line parallel to the first surface 112 or the second surface 122 of the housing 100, the space inside the housing 100 is largely exposed toward the rear of the housing 100 (the negative direction of the first direction X) when the second part 120 is removed from the first part 110. Therefore, it is easy to attach the optical device 200 to the space inside the housing 100 from the rear of the housing 100 (the negative direction of the first direction X). This makes it easy to accommodate the optical device 200 in the housing 100.

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

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

[0020] The power supply unit 310 is located in the front (positive direction of the first direction X) of the space in the housing 100 rather than the rear (negative direction of the first direction X) of the space in the housing 100. The power supply unit 310 is arranged in line with the optical device 200 in a direction (second direction Y) intersecting a direction (first direction X) from the first side surface 114 (window portion 130) side (front, i.e., positive direction of the first direction X) toward the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., negative direction of the first direction X). The control unit 320 is arranged in line with the optical device 200 and the power supply unit 310 in a direction (first direction X) from the first side surface 114 (window portion 130) side (front, i.e., positive direction of the first direction X) toward the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., negative direction of the first direction X). Moreover, the control unit 320 is located at the rear (negative direction of the first direction X) of the space in the housing 100 rather than at the front (positive direction of the first direction X) of the space in the housing 100. In general, the space for arranging the control unit 320 (for example, the control board 322, which will be described in detail later) needs to be larger than the space for arranging the power supply unit 310 (for example, the power supply board 312, which will be described in detail later). According to this embodiment, by arranging the optical device 200 and the power supply unit 310 along the second direction Y, a large space for arranging the control unit 320 can be secured behind the optical device 200 and the power supply unit 310 (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 in the housing 100.

[0021] The layout of the optical device 200 and the electronic device 300 is not limited to the layout 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 first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) to the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., 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 (negative direction of the first direction X), or the power supply unit 310 and the control unit 320 may be arranged in the area 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 boards 312. Each power supply board 312 has a thickness along a direction (first direction X) from the first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) toward the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., the negative direction of the first direction X). Furthermore, the plurality of power supply boards 312 are lined up along a direction (first direction X) from the first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) toward the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., the negative direction of the first direction X). In this case, each power supply board 312 can be efficiently arranged in the space within the housing 100, compared to a case in which each power supply board 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 a first support member 332. The first support member 332 is fixed to an inner surface of the housing 100 (first portion 110) on the front side (positive side of the first direction X) of the space inside the housing 100. A fastener such as a screw penetrating the power supply board 312 from the rear (negative side of the first direction X) to the front (positive side 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 fastener.

[0024] The control unit 320 includes a plurality (two) of control boards 322. Each control board 322 has a thickness along a direction (first direction X) from the first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) toward the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., the negative direction of the first direction X). Furthermore, the plurality of control boards 322 are lined up along a direction (first direction X) from the first side surface 114 (window portion 130) side (front, i.e., the positive direction of the first direction X) toward the opposite side (fourth side surface 124 side) of the first side surface 114 (window portion 130) (rear, i.e., 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, compared to a case in which 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, but 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 a second support member 334. The second support member 334 is fixed to the inner bottom surface of the lower side (negative side in the third direction Z) of the space inside the housing 100 (first portion 110). A fastener such as a screw penetrating the control board 322 from the rear (negative direction in the first direction X) to the front (positive direction in 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 fastener.

[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 in the housing 100 (first part 110) (negative side of the first direction X with respect to the control unit 320). In other words, the power supply terminal 314 is located in a region aligned with the power supply unit 310 in the first direction X when viewed from the third direction Z. In this case, for example, compared to a case in which the power supply unit 310 and the power supply terminal 314 are arranged offset 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 overall 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 offset 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 positioned offset from the center of the first part 110 of the housing 100 in the second direction Y toward the positive direction of 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 of the power supply terminal 314 in the second direction Y. 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 of the power supply terminal 314 in the second direction Y.

[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 the power supply wiring 316 and the control wiring 326, respectively. 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, in order to connect the power supply wiring 316 to the power supply unit 310 and the power supply terminal 314 when the notch 322a is not provided (for example, when the control board 322 has a rectangular shape), it is necessary to make the power supply wiring 316 detouring around 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 detouring around the power supply unit 310, the total length of the power supply wiring 316 may become longer. 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 may become larger. In contrast, in this embodiment, there is no need to detour the power supply wiring 316 around the power supply unit 310, and the overall length of the power supply wiring 316 can be shortened. Also, in this embodiment, there is no need to move the power supply unit 310 in the second direction Y or the third direction Z, and the space required to arrange the power supply unit 310 can be reduced. However, the control board 322 does not have to 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 housed in the housing 100 described using Fig. 1 to Fig. 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 Fig. 1 to Fig. 7, respectively.

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

[0031] The optical device 200 includes a transmitting section 210, a movable reflecting section 220, a receiving section 230, and a beam splitter 240. In Fig. 8, the transmitting section 210, the movable reflecting section 220, the receiving section 230, and the beam splitter 240 are typically located in a plane parallel to both the first direction X and the second direction Y. However, in an actual layout, the transmitting section 210, the movable reflecting section 220, the receiving section 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, electromagnetic waves propagating through the transmitting section 210, the movable reflecting section 220, the receiving section 230 and the beam splitter 240 are indicated by dashed lines.

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

[0034] The electromagnetic wave transmitted from the transmitting section 210 passes through the beam splitter 240, enters the movable reflecting section 220, and is reflected by the movable reflecting section 220. The movable reflecting section 220 is, for example, a MEMS (Micro Electro Mechanical Systems) mirror.

[0035] The electromagnetic wave reflected by the movable reflector 220 passes through the window 130 and is emitted toward the outside of the sensor device 10. The electromagnetic wave emitted toward the outside of 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 130 and is incident on the movable reflector 220. The electromagnetic wave incident on the movable reflector 220 is reflected by the movable reflector 220 and the beam splitter 240 in this order, and is incident on the receiver 230. The receiver 230 receives the electromagnetic wave incident on the receiver 230. In one example, the receiver 230 is an element (e.g., an avalanche photodiode (APD)) capable of converting an electromagnetic wave into electrical energy (e.g., a current).

[0036] The sensor device 10 is, for example, a 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 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 unit 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 unit 230).

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

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

[0039] For example, when the optical device 200 has a field of view that expands along the vertical direction (a direction along a plane parallel to both the first direction X and the third direction Z), the movable reflecting section 220 is capable of swinging about an axis extending along the second direction Y. That is, in accordance with the expansion of the field of view of the optical device 200, the movable reflecting section 220 is capable of swinging about at least one axis.

[0040] As shown in FIG. 3 and FIG. 4, the first shape portion 152 and the second shape portion 154 are provided on the outer surface of the housing 100. The first shape portion 152 and the second shape portion 154 are engageable with other shapes located outside the housing 100 (the relationship between the first shape portion 152 or the second shape portion 154 and other shapes located outside the housing 100 will be described in detail later). The field of view F can be positioned (fixed) by the first shape portion 152 and the second shape portion 154. Specifically, when viewed from the third direction Z (i.e., a direction perpendicular to the direction in which the field of view F spreads, or the extension direction of the axis 222), the first shape portion 152 and the second shape portion 154 are aligned on the same straight line L (i.e., when viewed from the third direction Z, a virtual straight line passing through the center of the field of view F of the optical device 200, 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 portion) with another shaped portion (i.e., the engaging portion) located outside the housing 100, it is possible to prevent the housing 100 from rotating around the third direction Z, and the field of view F (i.e., the straight line L) is positioned (fixed). Furthermore, 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 field of view F of the optical device 200 by using the first shaped portion 152 and the second shaped portion 154 as markers.

[0041] The first shaped portion 152 and the second shaped portion 154 may not be collinear with the straight line L, and may be offset 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 another shaped portion located outside the housing 100, it is possible to prevent the housing 100 from rotating around the third direction Z, and the field of view F is positioned.

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

[0043] The other shaped portion located outside the housing 100 and engaging with the first shaped portion 152 and the second shaped portion 154 can be a convex portion or a concave portion depending on whether the first shaped portion 152 and the second shaped portion 154 are a concave portion or a convex portion. For example, when the first shaped portion 152 (the second shaped portion 154) is a concave portion (e.g., a positioning hole), the other shaped portion located outside the sensor device 10 can be 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), the other shaped portion located outside the sensor device 10 can be 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 (first surface 112) of the housing 100 (first part 110). In this case, the field of view F can be positioned simply by placing the housing 100 on a placement surface on which other shaped portions that engage with the first shaped portion 152 and the second shaped portion 154 are provided. Therefore, the field of view F is easily positioned. However, the first shaped portion 152 and the second shaped portion 154 may be provided on a surface different from the bottom surface (first surface 112) of the housing 100 (first part 110). In addition, the first shaped portion 152 and the second shaped portion 154 may be provided on a common surface of the housing 100, such as when both the first shaped portion 152 and the second shaped portion 154 are provided on the first surface 112 of the housing 100 (first part 110) as in this embodiment. Alternatively, the first shaped portion 152 and the second shaped portion 154 may be provided on different surfaces, for example, the first shaped portion 152 being provided on the first surface 112 of the housing 100 (first part 110) and the second shaped portion 154 being provided on the second surface 122 of the housing 100 (second part 120).

[0045] The first shaped portion 152 is located on the rear side of the housing 100 (negative direction side of the first direction X) with respect to the second shaped portion 154. Also, the first shaped portion 152 is located behind the housing 100 (negative direction of the first direction X) rather than the front side of the housing 100 (positive direction of the first direction X). Furthermore, the first shaped portion 152 (recess) is provided at a portion where the bottom surface (first surface 112) of the housing 100 (first portion 110) and the outer side surface (the outer side surface on which the power terminal 314 and the control terminal 324 are provided) of the housing 100 (first portion 110) intersect. The second shaped portion 154 is located on the front side of the housing 100 (positive direction side of the first direction X) with respect to the first shaped portion 152. Also, the second shaped portion 154 is located ahead of the housing 100 (positive direction of the first direction X) rather than the rear side of the housing 100 (negative direction of the first direction X). Furthermore, the second shaped portion 154 is positioned shifted backward (in the negative direction of the first direction X) from the front side surface (first side surface 114) of the housing 100 (first part 110). However, the second shaped portion 154 (recess) may be provided at a portion where the bottom surface (first surface 112) of the housing 100 (first part 110) and the outer side surface (first side surface 114) of the housing 100 (first part 110) intersect, similar to 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 intersects with the outer side surface (for example, the first side surface 114, or the surface on which the power terminal 314 and the control terminal 324 are provided) of the housing 100.

[0046] In this embodiment, the field of view (field of view F) when viewed from the third direction Z is positioned by the first shaped portion 152 and the second shaped portion 154. However, even if the field of view is viewed from a direction different from the third direction Z, for example, the second direction Y, it can be positioned by using the first shaped portion 152 and the second shaped portion 154 according to a method similar to the method described in this embodiment.

[0047] FIG. 9 is a diagram showing a modification of FIG.

[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, the first shaped portion 152 (second shaped portion 154) is positioned outside the housing 100 and engaged with another shaped portion that is long in one direction, thereby preventing the housing 100 from rotating around the third direction Z, and the field of view F is positioned.

[0049] Although the embodiment and modified examples have been described above with reference to the drawings, these are merely 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 respectively a lower portion and an upper portion of the housing 100. However, the first portion 110 and the second portion 120 of the housing 100 may be, for example, an upper portion and a lower portion of the housing 100, respectively.

[0051] In this 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 this embodiment, the first portion 110 and the second portion 120 of the housing 100 are separable along a diagonal direction relative to 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 along a direction parallel to the first surface 112 or the second surface 122 of the housing 100.
