Detailed Description

Hereinafter, an imaging device according to an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

The use of the imaging device is not particularly limited, and the imaging device is suitably used as a monitoring camera or a nursing camera installed in a hospital, a nursing facility, a factory, a store, or the like. The imaging device according to the present embodiment is manufactured by mounting the camera module in the imaging device in either one of the 1 st mounting state and the 2 nd mounting state. In the 1 st mounting state, the camera module is mounted so as to be switchable between a photographable state and a non-photographable state. In the 2 nd mounting state, the camera module is mounted so as to be in a photographable state only. In the case of the 1 st mounting state, the image pickup apparatus can be switched to an off state in which light cannot be incident on the imaging optical system and an on state in which light can be incident on the imaging optical system. When the imaging device is switched to the non-photographable state (off state), the person to be photographed can recognize that the imaging device is switched to the non-photographable state. In the 2 nd mounting state, the imaging device always allows light to enter the imaging optical system.

The imaging device can switch between the normal imaging mode and the night vision mode according to the brightness of the surrounding external environment. In the normal photographing mode, photographing is performed by light incident on the imaging optical system when the external environment is bright. In the night vision mode, when the external environment is dark, illumination light is emitted, and an object irradiated with the illumination light is photographed.

Hereinafter, description will be given of an imaging device in the 1 st mounting state and an imaging device in the 2 nd mounting state.

The 1 st direction is a direction intersecting the optical axis L of the lens 111 included in the camera module 11 described later, and the 2 nd direction is a direction intersecting the 1 st direction and the optical axis L.

A circular 1 st opening 125 communicating with the inside and outside of the housing 12 is provided in the top plate 122 of the front case 120. In other words, the 1 st opening 125 is a through hole provided in the top plate 122. Light (subject light) emitted from an object (subject) to be imaged enters the housing 12 through the 1 st opening 125, and is incident on the imaging optical system.

The top plate 122 of the front case 120 is provided with an illumination opening 126 at a position corresponding to a position where the illumination unit 16 described later is disposed. That is, the illumination opening 126 is also a through hole provided in the top plate 122. The illumination light emitted from the illumination unit 16 illuminates an imaging target (subject) through the illumination opening 126.

As shown in fig. 1A to 2, 2 illumination openings 126 (one is a front side and the other is a rear side) are provided on the right side of the top plate 122, 2 illumination openings 126 (one is a front side and the other is a side wall plate rear side) are provided on the left side of the top plate 122, and a total of 4 illumination openings 126 are provided. However, the position of the illumination opening 126 is not limited to the illustrated position, and may be appropriately determined according to the arrangement position of the illumination portion 16. The number of the illumination openings 126 is not limited to 4, and may be 3 or less, or 5 or more, and is determined according to the number of the illumination portions 16 included in the imaging device 10.

Fig. 3 is a perspective view of the rear housing 121. The rear case 121 is fixed to the front case 120, closing the bottom (lower) of the front case 120. The rear case 121 is fixed to the front case 120 by, for example, screw-bonding. The rear case 121 has a rectangular or substantially rectangular bottom surface 121a similar to the top plate 122 of the front case 120, and side wall plates 121b, 121c, 121d, 121e contacting each side from the bottom surface 121 a. The bottom surface 121a and the side wall plates 121b, 121c, 121d, 121e are integrally molded from synthetic resin. The side wall plate 121b is connected to a front side (long side) of the bottom surface 121a, and the side wall plate 121c is connected to a rear side (long side) of the bottom surface 121 a. The side wall plate 121d is connected to the right side (short side) of the bottom surface 121a, and the side wall plate 121e is connected to the left side (short side) of the bottom surface 121 a.

A plurality of bosses 124 as protrusions extending toward one side (above) in the direction along the optical axis L of the lens 111 are formed on the upper surface of the bottom surface 121a (i.e., the inner side of the housing 12). The 1 st mounting holes 127 for mounting the camera module 11 are formed on the upper surfaces of the plurality of bosses 124, respectively. The bottom surface 121a has 2 bosses 124a, 124b. The boss 124a is provided on the front side near the central portion of the bottom surface 121a, and the boss 124b is provided on the rear side near the central portion of the bottom surface 121 a. That is, the 1 st mounting hole 127a formed in the boss 124a is provided on the front side in the vicinity of the central portion of the bottom surface 121a, and the 1 st mounting hole 127b formed in the boss 124b is provided on the rear side in the vicinity of the central portion of the bottom surface 121 a.

Fig. 4A is a cross-sectional view taken along line A-A of the image pickup apparatus 10 in the closed state shown in fig. 1B. As shown in fig. 4A, a distance (height) H1 in the up-down direction from the bottom surface 121a to the upper surface of the boss 124 is determined based on a size (height) H2 in the up-down direction of the camera module 11 described later attached to the boss 124 and a distance (height) H3 in the up-down direction from the bottom surface 121a to the blade 13 described later. Specifically, the heights H1, H2, H3 satisfy the relationship h1+h2 < H3. In addition, the height H2 is a distance in a direction along the optical axis L from the bottom surface of the substrate 112 provided in the camera module 11 to the upper end of the lens 111. The height H3 is a distance in a direction along the optical axis L from the bottom surface 121a to the lower surface of the blade 13. As a result, as will be described later, the camera module 11 attached to the boss 124 is disposed below the blade 13 described later.

The number of bosses 124 is not limited to 2, but may be 3 or more. In this case, the 1 st mounting hole 127 is formed in the upper surface of each boss 124. In addition, the heights of the bosses 124a, 124b may be different from each other. In this case, the camera module 11 can be held at the 1 st position by inserting an adjustment member such as a spacer between the boss 124 and the substrate 112. That is, the substrate 112 is fixed to the boss 124 via the adjusting member, and thereby the position of the holding substrate 112, that is, the height H1 from the bottom surface 121a can be finely adjusted.

< connector 25 >

As shown in fig. 2, the imaging device 10 has a connector 25 to which a power cable, a communication cable, or the like can be connected. More specifically, the imaging device 10 has a female connector 25 to which a USB cable can be connected.

The image pickup apparatus 10 further includes a memory slot 26 to which a predetermined recording medium can be connected. More specifically, the imaging device 10 has a slot into which the SD memory card can be inserted and removed. When the cover 260 provided on the rear case 121 is opened, the SD memory card can be inserted into and removed from the memory slot 26.

< Camera Module 11 >)

As shown in fig. 4A, the camera module 11 includes an image pickup device (image sensor) 110 such as a CMOS or a CCD, and a lens 111, and the camera module 11 is housed in a housing 12. The image pickup device 110 is mounted on a substrate 112. The lens 111 is, for example, a convex lens, has a predetermined curvature, and has a central portion (near the position of the optical axis L) protruding toward an imaging target object (subject). The lens 111 is disposed above the image pickup element 110 and held by a lens holder 113. The substrate 112 on which the image pickup device 110 is mounted is fixed below the lens holder 113 by, for example, screw-coupling.

Fig. 4B is a top view of the camera module 11 viewed from above. As shown in fig. 4B, a plurality of 1 st substrate mounting holes 114 and a plurality of 2 nd substrate mounting holes 115 are formed in the substrate 112. The substrate 112 has a 1 st substrate mounting hole 114a on the front side near the center portion and a 1 st substrate mounting hole 114b on the rear side near the center portion. The substrate 112 has a 2 nd substrate mounting hole 115a on the right front side, a 2 nd substrate mounting hole 115b on the right rear side, and a 2 nd substrate mounting hole 115c on the left front side. The number of the 1 st substrate mounting holes 114 is not limited to the above-described 2, but may be 3 or more. The number of the 2 nd substrate mounting holes 115 is not limited to the above-described 3, but may be 4 or more.

The object light entering the 1 st opening 125 is guided by the lens 111 to the light receiving surface of the image pickup element 110 and condensed. That is, the lens 111 is an optical member (imaging optical system) that forms an image of the image pickup object on the light receiving surface of the image pickup element 110, or at least a part of the optical member. The image pickup element 110 converts the light and shade of the image formed by the lens 111 into an electric charge amount, and outputs a signal (image signal) corresponding to the converted electric charge amount.

Antenna 27 >

Referring again to fig. 2. The image pickup apparatus 10 has an antenna 27, and can be connected to other devices via a wireless LAN (Wi-Fi). For example, the image pickup device 10 can wirelessly transmit a signal (image signal) output from the image pickup element 110 to other devices such as a smart phone and a tablet terminal. The imaging device 10 may be remotely operated by another device such as a smart phone.

< illumination portion 16 >)

The illumination unit 16 emits illumination light for illuminating the imaging object at the time of imaging in a dark surrounding environment (that is, at the time of imaging in the night vision mode). The illumination section 16 has an illumination light source 161 and a cover section 162. The illumination light source 161 is, for example, an LED, and is controlled by a control unit 31 described later to emit light having a wavelength in the infrared region (infrared light ). The illumination light source 161 is not limited to emitting infrared light as illumination light, and may emit visible light other than infrared light as illumination light. The illumination light source 161 is disposed on the base member 140 of the blade driving mechanism 14 described later.

The cover 162 is formed of, for example, a resin having light transmittance, and is provided on the emission side (upper side) of the illumination light source 161. The cover 162 has a surface covering at least the upper side of the illumination light source 161. The surface of the cover 162 is fitted into the illumination opening 126. In this case, the cover 162 is attached so that the surface does not protrude outward (upward) from the outer surface of the top plate 122 of the housing 12. The illumination light emitted from the illumination light source 161 is emitted through the cover 162 toward the outside of the imaging device 10.

As shown in fig. 1A to 2, the imaging device 10 includes 4 illumination units 16. A pair of the 4 illumination portions 16 is provided on the right side of the top plate 122, one illumination portion 16 is provided on the front side, and the other illumination portion 16 is provided on the rear side. The other pair of illumination portions 16 is on the left side of the top plate 122, one illumination portion 16 is provided on the front side, and the other illumination portion 16 is provided on the rear side.

The number of illumination units 16 included in the imaging device 10 is not limited to 4. The imaging device 10 may have 3 or less illumination units 16, or may have 5 or more illumination units 16.

< illuminometer 17 >)

The illuminometer 17 is, for example, a light register or a photodiode, and receives light of the environment (external environment) surrounding the imaging device 10. The illuminometer 17 is disposed on a base member 140 of the blade driving mechanism 14, which will be described in detail later. The illuminometer 17 converts the shade of the received light into an electric charge amount, and outputs a signal (luminance signal) corresponding to the electric charge amount. That is, the illuminometer 17 detects the brightness of the surrounding environment of the imaging device 10.

< control section 31 >)

The control unit 31 is disposed at the rear side in the housing 12 and mounted on the substrate 310. The control unit 31 is configured by, for example, a CPU, a memory, or the like, and is electrically connected to the substrate 112 on which the image pickup device 110 is mounted. The control unit 31 is, for example, a processor that reads and executes a control program recorded in advance in a recording medium such as a flash memory to control each unit of the imaging device 10. For example, the control unit 31 controls the power supply of the power supply unit 24 to the image pickup element 110 and the actuator 15.

The control unit 31 sets the night vision mode when the external environment of the imaging device 10 is dark, based on the luminance signal output from the illuminometer 17. In the night vision mode, when the external environment is dark and the amount of light is insufficient, the control unit 31 controls the illumination unit 16 to emit infrared light as illumination light, and illuminates the subject with the infrared light.

Blade 13 and blade drive mechanism 14 >

The blade driving mechanism 14 includes a base member 140 and an actuator 15, and the blade driving mechanism 14 is accommodated in the housing 12. The blade driving mechanism 14 moves the blade 13 in a direction along the long side of the top plate 122 (1 st direction), opens and closes the 1 st opening 125, and controls incidence of the object light to the lens 111. More specifically, the vane 13 is moved by the vane drive mechanism 14 to a closed position closing the 1 st opening portion 125 and an open position opening the 1 st opening portion 125. The vane 13 in the closed position functions as a light shielding portion that shields the 1 st opening 125 and restricts the incidence of the subject light to the imaging element 110.

In other words, the blade driving mechanism 14 switches the 1 st opening 125 of the imaging apparatus 10 from the open state (fig. 1A) to the closed state (fig. 1B). The blade driving mechanism 14 switches the 1 st opening 125 of the imaging device 10 from the closed state (fig. 1B) to the open state (fig. 1A). Thus, the lens 111 is covered in the closed state (fig. 1B), and the lens 111 is exposed in the open state (fig. 1A).

< base member 140 >)

Fig. 5 is an external perspective view of the base member 140 from below. The base member 140 is described with reference to fig. 2 and 5. The base member 140 is molded from, for example, synthetic resin, and is integrally molded from a main base portion 141 and a sub base portion 142. The main base portion 141 is located on the top plate 122 side (upper side) of the housing 12 with respect to the lens 111. The sub base portion 142 is formed with a screw hole for screw-coupling with the rear case 121 in a part thereof, and is erected downward from the main base portion 141. The sub base portion 142 is screwed to fix the base member 140 to the rear case 121, thereby fixing the base member to the rear case 121. By the base member 140 having the above-described shape, the imaging element 110 can be disposed on the lower side (rear case 121 side) with respect to the main base portion 141.

The main base portion 141 is formed with a circular opening 143 communicating with the upper and lower sides of the base member 140 around a position where the optical axis L of the lens 111 passes. In other words, the opening 143 is a through hole provided in the main base portion 141. Light (subject light) emitted from an object (subject) to be imaged and passing through the 1 st opening 125 provided in the housing 12 enters the lens 111 through the opening 143.

At least the blade 13, the actuator 15, the illumination unit 16, and the illuminometer 17 are mounted on the main base portion 141. The blade 13, the illumination unit 16, and the illuminometer 17 are mounted on the upper side of the main base portion 141. The number of illumination units 16 is 2 on each of the right and left sides of the main base unit 141. The illuminometer 17 is disposed on the right side of the main base portion 141 with respect to the opening 143.

A plurality of bosses 144 as protrusions extending to the other side (downward) in the direction along the optical axis L of the lens 111 are formed on the surface of the lower side (image pickup element 110 side) of the main base portion 141. A 2 nd mounting hole 145 for mounting the camera module 11 is formed on a lower surface of each of the plurality of bosses 144. As shown in fig. 5, 3 bosses 144a, 144b, 144c are formed on the main base portion 141. The boss 144a is formed on the right front side with respect to the opening 143 of the main base portion 141. The boss 144b is formed on the right rear side with respect to the opening 143 of the main base portion 141. The boss 144c is formed on the left front side with respect to the opening 143 of the main base portion 141.

A 2 nd mounting hole 145a is formed on the lower surface of the boss 144a, a 2 nd mounting hole 145b is formed on the lower surface of the boss 144b, and a 2 nd mounting hole 145c is formed on the lower surface of the boss 144c. The number of the bosses 144 is not limited to 3, and may be 2 or 4 or more. In this case, the 2 nd mounting holes 145 are also formed on the lower surface of each boss 144.

The position of the lower surface of the boss 144 in the up-down direction is different from the position of the upper surface of the boss 124 provided on the bottom surface 121a of the rear case 121 in the up-down direction. Specifically, the lower surface of the boss 144 is located above the upper surface of the boss 124. More specifically, the 2 nd mounting hole 145 is formed on the lens 111 side of the 1 st mounting hole 127 in a direction (up-down direction) along the optical axis L of the lens 111.

Actuator 15 >, actuator

The actuator 15 is mounted on the rear case 121 side (lower side) with respect to the main base portion 141. In other words, the actuator 15 is mounted on the inner side of the base member 140. The actuator 15 may be arranged on the side where the imaging element 110 is arranged with respect to the blade 13.

The actuator 15 functions as a driving unit that moves the blade 13 in the 1 st direction. The actuator 15 has a motor 151, a rotation shaft 152, and a gear 153. The motor 151 has, for example, a coil, a yoke, a magnet, or the like, and is rotated by electric power (current) supplied from the power supply unit 24 under the control of the control unit 31. The rotation direction of the motor 151 is reversed according to the direction of the current supplied to the coil. For example, when a current in a certain direction flows through the coil, the motor 151 rotates clockwise, and when a current in the opposite direction flows through the coil, the motor 151 rotates counterclockwise.

The rotation shaft 152 extends in the 2 nd direction and engages with the gear 153. The rotation shaft 152 is rotationally driven by rotation of the motor 151. The gear 153 engaged with the rotation shaft 152 rotates according to the rotation drive of the rotation shaft 152. As described above, the rotation direction of the motor 151 is reversed according to the direction of the supplied current. Accordingly, the rotation shaft 152 and the gear 153 are also reversed in rotation direction according to the direction of the current supplied to the motor 151. The gear 153 engages with a rack portion formed in the blade 13 described later.

< blade 13 >)

The blade 13 is molded, for example, from a synthetic resin or a metal material. The vane 13 is supported on the main base portion 141 of the base member 140 so as to be capable of straight movement (slidable). In other words, the base member 140 is a supporting portion that supports the blades 13 as light shielding portions. The blade 13 is a thin plate having the 1 st direction as a longitudinal direction, and is disposed on an upper portion of the base member 140 so as to overlap the base member 140. More specifically, the blade 13 overlaps the main base portion 141, and partially covers the main base portion 141.

The vane 13 has a 2 nd opening 133 communicating with the upper and lower sides of the vane 13. In other words, the 2 nd opening 133 is a through hole provided in the vane 13. The 2 nd opening 133 allows the subject light passing through the 1 st opening 125 formed in the top plate 122 to pass through when the blade 13 is in the open position.

A rack portion having a plurality of teeth aligned in the left-right direction (1 st direction) is provided on the lower surface of the vane 13. The vane 13 is engaged with the gear 153 of the actuator 15 via the rack portion. When the gear 153 is driven with the rotation of the motor 151 as described above, the rack portion converts the rotational force into a linear movement force along the 1 st direction. As a result, a moving force in the 1 st direction acts on the blade 13, and the blade 13 moves in the 1 st direction. That is, the vane 13 is movable (slidable) in the 1 st direction between the base member 140 (main base portion 141) and the front case 120 (top plate 122). In other words, the vane 13 can move in the 1 st direction, but cannot move in other directions, and cannot rotate.

< mounting of camera Module 11 >

Hereinafter, the mounting of the camera module 11 in the imaging apparatus 10 in the 1 st mounted state will be described. Fig. 6 is a perspective view of the rear housing 121 in a state where the camera module 11 is mounted.

In the 1 st mounted state, the camera module 11 is mounted to the 1 st mounting hole 127 formed in the bottom surface 121a of the rear case 121. Specifically, the 1 st substrate mounting hole 114 of the substrate 112 and the 1 st mounting hole 127 of the bottom surface 121a of the camera module 11 disposed on the boss 124 are fixed (fastened) by screw engagement of the screw 400 inserted from above. In this case, the 1 st substrate mounting hole 114a of the substrate 112 and the 1 st mounting hole 127a of the bottom surface 121a are fixed by the screw 400a, and the 1 st substrate mounting hole 114b of the substrate 112 and the 1 st mounting hole 127b of the bottom surface 121a are fixed by the screw 400 b.

As described above, the height H1 in the up-down direction from the bottom surface 121a to the upper surface of the boss 124, the size H2 in the up-down direction of the camera module 11 mounted on the boss 124, and the distance H3 in the up-down direction between the bottom surface 121a and the blade 13 satisfy the relationship h1+h2 < H3 (see fig. 4A). Therefore, the upper end of the lens 111 of the camera module 11 held by the boss 124 is located below the lower surface of the blade 13. In other words, the boss 124 functions as a 1 st holding portion that holds the camera module 11 in the 1 st position satisfying the above relationship in the housing 12. As a result, the lens 111 of the held camera module 11 can switch the imaging device 10 between the open state shown in fig. 1A and the closed state shown in fig. 1B without interfering with the movement of the blade 13 in the lateral direction.

< 2 nd mounting State >

Fig. 7 is an external perspective view of the imaging device 10 in the 2 nd mounted state. Unlike the imaging device 10 in the 1 st mounted state, the imaging device 10 in the 2 nd mounted state has the lens 111 of the camera module 11 protruding outward (upward) from the 1 st opening 125 formed in the top plate 122 of the front case 120. In other words, the imaging device 10 in the 2 nd attachment state does not have the blade 13 and the actuator 15 that move the blade 13 that the imaging device 10 in the 1 st attachment state has. The other configuration of the imaging apparatus 10 in the 2 nd attachment state is the same as that of the imaging apparatus 10 in the 1 st attachment state. However, in the imaging device 10 in the 2 nd mounted state, the fixation of the substrate 112 of the camera module 11 is different from the case of the imaging device 10 in the 1 st mounted state. Specifically, the substrate 112 of the camera module 11 is mounted to the plurality of bosses 144 of the base member 140. Hereinafter, the mounting of the camera module 11 of the imaging apparatus 10 in the 2 nd mounted state will be described in detail.

Fig. 8A is a perspective view of the base member 140 in a state where the camera module 11 is mounted, and fig. 8B is a cross-sectional view of the image pickup apparatus 10 at line B-B shown in fig. 7.

The camera module 11 is mounted to a 2 nd mounting hole 145 formed in the lower surface of the main base portion 141 of the base member 140. Specifically, the 2 nd substrate mounting hole 115 of the substrate 112 provided in the camera module 11 disposed below the boss 144 and the 2 nd mounting hole 145 of the lower surface of the boss 144 are fixed (fastened) by screwing the screw 401 inserted from below. In this case, the 2 nd substrate mounting hole 115a of the substrate 112 and the 2 nd mounting hole 145a of the boss 144a are fixed by the screw 401a, the 2 nd substrate mounting hole 115b of the substrate 112 and the 2 nd mounting hole 145b of the boss 144b are fixed by the screw 401b, and the 2 nd substrate mounting hole 115c of the substrate 112 and the 2 nd mounting hole 145c of the boss 144c are fixed by the screw 401 c.

In the 1 st mounted state described above, the base plate 112 of the camera module 11 is fixed to the boss 124 of the rear case 121 by the screw 400 from above. In contrast, in the 2 nd attached state, the substrate 112 of the camera module 11 is fixed to the base member 140 by the screw 401 from below. That is, the direction in which the screw 401 for fastening the base plate 112 to the boss 144 is inserted is different from the direction in which the screw 400 for fastening the base plate 112 to the boss 124 is inserted.

In addition, as described above, the lower surface of the boss 144 is located above the upper surface of the boss 124 formed on the bottom surface 121a of the rear case 121. As shown in fig. 8B, the size (height) H4 in the up-down direction from the lower surface of the boss 144 to the upper end of the base member 140 is smaller than the size (height) H5 in the up-down direction from the upper surface of the substrate 112 of the camera module 11 to the upper end of the lens 111. Therefore, the lens 111 in the camera module 11 protrudes upward with respect to the top plate 122 of the front case 120. In other words, the boss 144 functions as a 2 nd holding portion that holds the camera module 11 in the 2 nd position satisfying the above relationship in the housing 12. In addition, the heights of the bosses 144a, 144b, 144c may be different. In this case, the camera module 11 can be held at the 2 nd position by inserting an adjustment member such as a spacer between the boss 144 and the substrate 112. That is, the substrate 112 is fixed to the boss 144 via the adjustment member, whereby the position of the holding substrate 112, that is, the height H4 from the substrate 112 to the upper end of the base member 140 can be finely adjusted.

As described above, the camera module 11 is held by either the boss 124 as the 1 st holding portion or the boss 144 as the 2 nd holding portion. Thus, the imaging device 10 in which the camera module 11 is held at either the 1 st position or the 2 nd position can be manufactured without increasing the number of components.

According to the above embodiment, the following operational effects can be obtained.

(1) The imaging device 10 includes: a boss 124 that is a plurality of 1 st holding portions that hold the camera module 11 at the 1 st position inside the housing 12; and a boss 144 that is a plurality of 2 nd holding portions that hold the camera module 11 in a 2 nd position different from the 1 st position in the housing 12. The camera module 11 is held by either one of the boss 124 and the boss 144. Thus, the imaging device 10 that holds the camera module 11 in either the 1 st position or the 2 nd position different from each other can be manufactured without increasing the number of components.

(2) The base 112 and the boss 124 or the boss 144 of the camera module 11 are fixed by a screw 400 or a screw 401. Thereby, the substrate 112 of the camera module 11 can be fixed by a simple method.

(3) The direction in which the screw 400 for fastening the base plate 112 to the boss 124 is inserted is different from the direction in which the screw 401 for fastening the base plate 112 to the boss 144 is inserted. Specifically, the boss 124 is formed in the housing 12 and is a protrusion extending to one side (above) in the direction along the optical axis L of the lens 111. The boss 144 is formed on the base member 140 as a support portion for supporting the blade 13 as a light shielding portion for shielding the image pickup element 110 from light, and is a protrusion extending to the other side (downward) in the direction along the optical axis L of the lens 111. Thus, the camera module 11 can be mounted at either one of the 1 st position or the 2 nd position, which are different from each other, without increasing the number of components.

The imaging device 10 of the above embodiment can be modified as follows.

< modification 1 >

In the embodiment, the boss 124 is a protrusion extending upward from the bottom surface 121a of the rear case 121 constituting the housing 12, and the boss 144 is a protrusion extending downward from the lower surface of the base member 140. However, the boss 124 and the boss 144 are not limited to this example, and may be protrusions extending in the same direction in the up-down direction (along the optical axis L). For example, as shown in the perspective view of the rear case 121 of fig. 9A, the bosses 124 (124 a, 124 b) and the bosses 144 (144 a, 144b, 144 c) may each be formed to extend upward from the bottom surface 121a of the rear case 121. In the 1 st mounting state, the base plate 112 is fixed to the boss 124 by the screw 400 from above, and the boss 124 functions as a 1 st holding portion. In the 2 nd attachment state, the base plate 112 is fixed to the boss 144 by the screw 401 from above, whereby the boss 144 functions as a 2 nd holding portion. That is, in the 1 st mounting state and the 2 nd mounting state, the direction in which the screw 400 fastening the base plate 112 to the boss 124 is inserted and the direction in which the screw 401 fastening the base plate 112 to the boss 144 is inserted are the same.

In this case, in the direction (up-down direction) along the optical axis L of the lens 111, the height from the upper surface of the bottom surface 121a to the upper surface of the boss 124 and the height from the upper surface of the bottom surface 121a to the upper surface of the boss 144 are different from each other. Specifically, the upper surface of the boss 144 is formed to be located at a position higher (above) than the upper surface of the boss 124 in the up-down direction. As described above, the boss 124 as the 1 st holding portion and the boss 144 as the 2 nd holding portion extend in the same direction, and thus in order to prevent interference between the substrate 112 and the boss 144 when the substrate 112 is fixed to the boss 124, an opening avoiding the boss 144 may be formed on the substrate 112.

Alternatively, as shown in the perspective view of the base member 140 in fig. 9B, the bosses 124 (124 a, 124B) and the bosses 144 (144 a, 144B, 144 c) may each be a protrusion extending downward from the lower surface of the base member 140. In the 1 st mounting state, the base plate 112 is fixed to the boss 124 by the screw 400 from below, and the boss 124 functions as a 1 st holding portion. In the 2 nd attachment state, the base plate 112 is fixed to the boss 144 by the screw 401 from below, and thus the boss 144 functions as a 2 nd holding portion. That is, in the 1 st mounting state and the 2 nd mounting state, the direction in which the screw 400 fastening the base plate 112 to the boss 124 is inserted and the direction in which the screw 401 fastening the base plate 112 to the boss 144 is inserted are the same.

In this case, the height from the upper end of the base member 140 to the lower surface of the boss 124 and the height from the upper end of the base member 140 to the lower surface of the boss 144 are different from each other in the direction (up-down direction) along the optical axis L of the lens 111. Specifically, the lower surface of the boss 144 is formed to be located at a position higher (above) than the lower surface of the boss 124 in the up-down direction. As described above, the boss 124 as the 1 st holding portion and the boss 144 as the 2 nd holding portion extend in the same direction, and thus in order to prevent interference between the substrate 112 and the boss 124 when the substrate 112 is fixed to the boss 144, an opening avoiding the boss 124 may be formed on the substrate 112.

< modification 2 >

In the embodiment and the 1 st modification, the camera module 11 is held at any one of the 1 st position and the 2 nd position which are different in the up-down direction along the optical axis L of the lens 111, but the present invention is not limited to this example. For example, in the 1 st attached state, the camera module 11 is held above the image pickup device 10 so as to be able to shoot, as in the embodiment and the 1 st modification, and in the 2 nd attached state, the camera module 11 is held so as to be able to shoot in either the front-rear-left-right direction of the image pickup device 10. In this case, in the 1 st mounted state, the boss 124 described in the embodiment is used as the 1 st holding portion, and the substrate 112 of the camera module 11 is fixed to the boss 124 by the screw 400. In this case, the camera module 11 is held upward so as to be able to shoot. That is, the camera module 11 is held such that the optical axis L of the lens 111 extends in the up-down direction (the 1 st fixing direction).

In the 2 nd attachment state, for example, the camera module 11 is held on the front side so as to be able to shoot. A plurality of bosses 144 as protrusions extending forward are formed as the 2 nd holding portions on the side wall plate 123b of the front case 120 or the side wall plate 121c of the rear case 121. Fig. 10 is a perspective view of the rear case 121 in this case. Fig. 10 shows a case where 2 bosses 144 are formed on the side wall plate 121c of the rear case 121. The base plate 112 of the camera module 11 is fixed to the boss 144 by screws from the front, whereby the camera module 11 is held in the front so as to be able to shoot. That is, the camera module 11 is held such that the optical axis L of the lens 111 extends in the front-rear direction (the 2 nd fixing direction) intersecting the up-down direction which is the 1 st fixing direction. In addition, when the camera module 11 is held in the rear so as to be able to shoot, a plurality of bosses as protrusions extending rearward are formed as the 2 nd holding portion on the side wall plate 123a of the front case 120 or the side wall plate 121b of the rear case 121 on the front side.

In addition, when the camera module 11 is held in the right direction so as to be able to shoot, a plurality of bosses as protrusions extending toward the right direction are formed as the 2 nd holding portion on the side wall plate 123d of the front case 120 or the side wall plate 121e of the rear case 121 on the left side. When the camera module 11 is held in the left direction so as to be able to shoot, a plurality of bosses as protrusions extending toward the left direction are formed as the 2 nd holding portions on the side wall plate 123c of the front case 120 or the side wall plate 121d of the rear case 121 on the right side. Thereby, the camera module 11 is held such that the optical axis L of the lens 111 extends in the right-left direction (the 2 nd fixing direction) intersecting the up-down direction which is the 1 st fixing direction.
