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.

The top plate 122 of the front case 120 is provided with a circular 1 st opening 125 communicating with the inside and outside of the housing 12. 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. 3A is a perspective view of the rear housing 121 as seen from below, and fig. 3B is an internal plan 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 connected to the respective sides 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 1 st connection opening 200 is formed near the right end of the bottom surface 121a so as to face the outside of a connection terminal 250 (see fig. 5A and 5B) of the connector 25 to be described later. The side wall plate 121d has a 2 nd connection opening 201 for allowing a connection terminal 250 of the connector 25 to be described later to face outward.

On the upper surface of the bottom surface 121a (i.e., on the inner side of the housing 12), a pair of 1 st mounting holes 202a and 202b and a pair of 2 nd mounting holes 203a and 203b for mounting the connector 25 are formed in the protruding portion protruding upward. The 1 st mounting hole 202a is provided on the right front side of the bottom surface 121a, and the 1 st mounting hole 202b is provided on the right rear side of the bottom surface 121 a. When the connection terminal 250 of the connector 25 is made to face outward from the 1 st connection opening 200, the connector 25 is screwed to the 1 st mounting holes 202a, 202b.

The 2 nd mounting hole 203a is provided on the right front side of the bottom surface 121a to the left of the 1 st mounting hole 202 a. The 2 nd mounting hole 203b is provided on the right rear side of the bottom surface 121a to the left of the 1 st mounting hole 202b. When the connection terminal 250 of the connector 25 is made to face outward from the 2 nd connection opening 201, the connector 25 is screwed to the 2 nd mounting holes 203a, 203b.

Memory slot 26 >

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 >)

Fig. 4 is a cross-sectional view taken along line A-A of the image pickup apparatus 10 in the closed state shown in fig. 1B. The camera module 11 includes an image pickup element (image sensor) 110 such as a CMOS or a CCD, and a lens 111. 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.

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 emits light (infrared light or infrared light) having a wavelength in the infrared region under control of the control unit 31 described later. 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 to the outside of the imaging device 10 through the surface of the cover 162.

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.

Blade 13 and blade drive mechanism 14 >

The blade drive mechanism 14 has a base member 140 and an actuator 15. 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 open 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 >)

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 rear case 121.

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 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 with respect to the opening 143 in the main base portion 141.

Actuator 15 >, actuator

The actuator 15 functions as a driving unit for moving the blade 13 in the 1 st direction, and details thereof will be described later. The actuator 15 has a motor 151, a rotation shaft 152, and a gear 153. The motor 151 includes, for example, a coil, a yoke, a magnet, and 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, which will be 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). 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. When the blade 13 is in the open position, 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.

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 in accordance with the rotation of the motor 151 controlled by the control unit 31 as described above, the rack unit 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).

< connector 25 >

As shown in fig. 2, the imaging apparatus 10 has a connector 25 connectable to an external device via a power cable, a communication cable, or the like. Fig. 5A is an external perspective view of the connector 25 mounted to the rear case 121, and fig. 5B is an exploded perspective view of the connector 25 mounted to the rear case 121. Fig. 6 is an external perspective view of the connector 25 mounted to the rear case 121.

The connector 25 has a connection terminal 250, a substrate 251, and a holding member 252. The connection terminal 250 is, for example, a female terminal to which a USB cable can be connected. The connection terminal 250 is mounted on the substrate 251 and electrically connected to the substrate 240 provided with the power supply portion 24. The connection terminal 250 faces either the 1 st connection opening 200 formed in the right bottom surface 121a of the rear case 121 or the 2 nd connection opening 201 formed in the side wall plate 121d of the rear case 121. When the connection terminal 250 faces outward from the 1 st connection opening 200, the connection terminal 250 is connected to an external device below the image pickup apparatus 10. In this case, the direction in which the connection terminal 250 faces (i.e., the lower direction) is referred to as the 1 st connection direction. When the connection terminal 250 faces outward from the 2 nd connection opening 201, the connection terminal 250 is connected to an external device on the right side of the image pickup apparatus 10. In this case, the direction in which the connection terminal 250 faces (i.e., the right direction) is referred to as the 2 nd connection direction. Accordingly, fig. 5A and 5B show a state in which the connection terminal 250 is oriented in the 1 st connection direction, and fig. 6 shows a state in which the connection terminal 250 is oriented in the 2 nd connection direction.

< holding part 252 >)

The holding member 252 is attached to the bottom surface 121a of the rear case 121 and is housed in the housing 12 in a state in which the connection terminal 250 attached to the substrate 251 is held in the 1 st connection direction or the 2 nd connection direction. The holding member 252 includes a main body 300, 1 st holding surfaces 320a and 320b (collectively referred to as 1 st holding surfaces 320), 2 nd holding surfaces 330a and 330b (collectively referred to as 2 nd holding surfaces 330), 1 st closing portions 340, 2 nd closing portions 350, and fixing portions 360 and 361, and is integrally molded of synthetic resin, for example. The main body 300 is formed in a rectangular parallelepiped or substantially rectangular parallelepiped shape.

Hereinafter, each portion of the holding member 252 will be described in detail. In addition, unless otherwise specified, the positional relationship of the respective parts and the like will be described with reference to the positional relationship when the connection terminal 250 is held in the 1 st connection direction as shown in fig. 5A and 5B.

< 1 st holding surface 320 >)

The 1 st holding surface 320 is a surface for holding the connection terminal 250 in the 1 st connection direction. Specifically, a board 251 is mounted on the 1 st holding surface 320, and the board 251 is mounted with the connection terminal 250. As shown in fig. 5A and 5B, the 1 st holding surface 320 is formed on the left surface of the main body 300. The 1 st holding surface 320 is a surface perpendicular or substantially perpendicular to the 1 st direction (left-right direction) when the holding member 252 is attached to the bottom surface 121a of the rear case 121. The 1 st holding surface 320a is a surface located in front of the main body 300, and the 1 st holding surface 320b is a surface located in rear of the main body 300. A screw hole 321 is formed in the 1 st holding surface 320a, and a screw hole 322 is formed in the 1 st holding surface 320 b.

< 2 nd holding surface 330 >)

As shown in fig. 6, the 2 nd holding surface 330 is a surface for holding the connection terminal 250 in the 2 nd connection direction. Specifically, the 2 nd holding surface 330 is a surface on which the substrate 251 on which the connection terminal 250 is mounted, and is a surface perpendicular or substantially perpendicular to the 1 st holding surface 320. That is, the 2 nd holding surface 330 is a surface perpendicular or substantially perpendicular to the optical axis L of the lens 111 when the connection terminal 250 is held by the 1 st holding surface 320 in the 1 st connection direction. As shown in fig. 5A and 5B, the 2 nd holding surface 330a is a lower surface of the 1 st holding surface 320a located in front of the main body 300. The 2 nd holding surface 330b is a lower surface of the 1 st holding surface 320a located at the rear of the main body 300. In other words, it can be said that the 2 nd holding surface 330 is formed on the lower surface of the main body 300. A screw hole 331 is formed in the 2 nd holding surface 330a, and a screw hole 332 is formed in the 2 nd holding surface 330 b.

< 1 st closure 340 >)

As shown in fig. 5A, the 1 st closing portion 340 protrudes rightward from the right side surface of the main body 300. The cross-sectional shape of the 1 st closing portion 340 in the plane perpendicular or substantially perpendicular to the 1 st direction (left-right direction) is the same as or substantially the same as the shape of the 2 nd connecting opening portion 201 formed in the side wall plate 121d of the rear case 121. Therefore, when the connector 25 having the connection terminal 250 held in the 1 st connection direction is mounted on the bottom surface 121a, the 1 st closing portion 340 can close the 2 nd connection opening 201.

< 2 nd closure portion 350 >)

The 2 nd closing portion 350 protrudes upward from an upper surface of the main body 300. The cross-sectional shape of the 2 nd closed portion 350 in a plane perpendicular or substantially perpendicular to the direction (up-down direction) of the optical axis L of the lens 111 is the same as or substantially the same as the shape of the 1 st connection opening 200 formed in the bottom surface 121a of the rear case 121. Therefore, when the connector 25 having the connection terminal 250 held in the 2 nd connection direction is mounted on the bottom surface 121a, the 2 nd closing portion 350 can close the 1 st connection opening 200.

< fixing portion 360, 361 >)

The fixing portion 360 is provided on the front surface of the main body 300, and has a through hole formed in a surface perpendicular or substantially perpendicular to the vertical direction. The fixed portion 361 is provided on a rear surface of the main body 300, and has a through hole formed in a surface perpendicular or substantially perpendicular to the vertical direction. The holding member 252 of the connector 25 is fixed to the 1 st mounting holes 202a, 202b or the 2 nd mounting holes 203a, 203b formed in the bottom surface 121a of the rear case 121 by screws inserted into the through holes of the fixing portions 360, 361.

Next, the mounting of the connector 25 to the rear case 121 in the case where the connection terminal 250 is oriented in the 1 st connection direction and in the case where the connection terminal 250 is oriented in the 2 nd connection direction will be described.

< 1 st connection direction >)

In addition to fig. 5A and 5B, the description will be made with reference to fig. 7A and 7B. Fig. 7A is an internal plan view of the rear case 121 to which the connector 25 having the connection terminal 250 directed in the 1 st connection direction is attached, and fig. 7B is an external perspective view when the rear case 121 to which the connector 25 having the connection terminal 250 directed in the 1 st connection direction is attached is viewed from below.

As shown in fig. 5A and 5B, the substrate 251 to which the connection terminal 250 is attached is fixed to the 1 st holding surface 320 by the screw 400 from the left side in a state in which the 1 st holding surface 320 of the holding member 252 is directed to the left side and the 2 nd holding surface 330 is directed to the lower side. At this time, the substrate 251 is fixed so that the connection terminal 250 is directed downward (i.e., the 1 st connection direction).

As shown in fig. 7A, the holding member 252 to which the substrate 251 is fixed as described above is attached to the 1 st attachment holes 202a, 202b formed in the bottom surface 121a of the rear case 121. Specifically, the 2 nd holding surface 330 of the holding member 252 and the connection terminal 250 are housed in the right end portion of the rear case 121 in a state where the 1 st closing portion 340 protrudes rightward (i.e., in a state shown in fig. 5A) in which they are oriented downward (1 st connection direction). The fixing portion 360 and the 1 st mounting hole 202a of the holding member 252 are fixed by the screw 410a, and the fixing portion 361 and the 1 st mounting hole 202b of the holding member 252 are fixed by the screw 410 b.

As a result, as shown in fig. 7B, the connection terminal 250 is inserted into the 1 st connection opening 200 formed in the bottom surface 121a of the rear case 121, and the connection terminal 250 faces outward. Therefore, it can be said that the 1 st mounting holes 202a, 202b formed in the bottom surface 121a of the rear case 121 function as 1 st positioning portions that determine the positions of mounting the holding members 252 that hold the connection terminals 250 in the 1 st connection direction. The bottom surface 121a can be said to be the 1 st surface having the 1 st connection opening 200 for facing the connection terminal 250 held in the 1 st connection direction to the outside. Further, the 1 st closing portion 340 protruding rightward from the main body 300 of the holding member 252 is inserted into the 2 nd connecting opening 201 formed in the side wall plate 121d of the rear case 121, and closes the 2 nd connecting opening 201. This suppresses entry of trash or the like from the 2 nd connection opening 201, into which the connection terminal 250 is not inserted, into the interior of the housing 12.

< connection direction 2 >)

In addition to fig. 6, the description will be made with reference to fig. 8A and 8B. Fig. 8A is an internal plan view of the rear case 121 to which the connector 25 of the connection terminal 250 directed in the 2 nd connection direction is attached, and fig. 8B is an external perspective view when the rear case 121 to which the connector 25 of the connection terminal 250 directed in the 2 nd connection direction is attached is viewed from below.

In the case of orienting the connection terminal 250 in the 2 nd connection direction, the up-down direction of the holding member 252 in the case of orienting the connection terminal 250 in the 1 st connection direction shown in fig. 5A is reversed. Specifically, the 2 nd holding surface 330 is directed upward in a state where the 1 st closing portion 340 protrudes rightward relative to the main body 300. Accordingly, when the connection terminal 250 is oriented in the 1 st connection direction, the 2 nd closing portion 350 protruding upward with respect to the main body portion 300 protrudes downward as shown in fig. 6. With respect to the holding member 252 in this state, the substrate 251 is fixed to the 2 nd holding surface 330 by the screw 400 from the upper side. At this time, the connection terminal 250 mounted on the substrate 251 is fixed to face the right (i.e., the 2 nd connection direction).

As shown in fig. 8A, the holding member 252 to which the substrate 251 is fixed as described above is attached to the 2 nd attachment holes 203a, 203b formed in the bottom surface 121a of the rear case 121. Specifically, the connection terminal 250 is housed in the right end portion of the rear case 121 in a state where the 2 nd closing portion 350 protrudes downward (i.e., a state shown in fig. 6). The fixing portion 361 and the 2 nd mounting hole 203a of the holding member 252 are fixed by a screw 410a, and the fixing portion 360 and the 2 nd mounting hole 203b of the holding member 252 are fixed by a screw 410 b.

As a result, as shown in fig. 8B, the connection terminal 250 is inserted into the 2 nd connection opening 201 formed in the side wall plate 121d of the rear case 121, and the connection terminal 250 faces outward. Therefore, it can be said that the 2 nd mounting holes 203a, 203b formed in the bottom surface 121a of the rear case 121 function as 2 nd positioning portions that determine positions at which the holding members 252 that hold the connection terminals 250 in the 2 nd connection direction are mounted. The side wall plate 121d may be said to be the 2 nd surface having the 2 nd connection opening 201 for allowing the connection terminal 250 held in the 2 nd connection direction to face outward. Further, the 2 nd closing portion 350 protruding downward with respect to the main body portion 300 of the holding member 252 is inserted into the 1 st connection opening 200 formed in the bottom surface 121a of the rear case 121, and closes the 1 st connection opening 200. This suppresses entry of waste or the like from the 1 st connection opening 200, into which the connection terminal 250 is not inserted, into the interior of the housing 12.

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

(1) The holding member 252 has a 1 st holding surface 320 for holding the connection terminal 250 in the 1 st connection direction and a 2 nd holding surface 330 for holding the connection terminal 250 in the 2 nd connection direction. The holding member 252 is housed in the housing 12 in a state where the connection terminal 250 is held by either one of the 1 st holding surface 320 and the 2 nd holding surface 330. Thus, a power cable or the like connected to an external device can be connected to the imaging apparatus 10 from any one of the 1 st connection direction and the 2 nd connection direction different from each other. Therefore, the degree of freedom in the posture when the imaging device 10 is arranged is increased as compared with a case of a structure in which the power cable or the like is connected from only one direction, and the number of places that can be used as the arrangement place of the imaging device 10 can be increased.

(2) The housing 12 has: a bottom surface 121a (1 st surface) having a 1 st connection opening 200 for facing the connection terminal 250 held in the 1 st connection direction to the outside; and a side wall plate 121d (2 nd surface) having a 2 nd connection opening 201 for facing the connection terminal 250 held in the 2 nd connection direction outward. The holding member 252 has: a 1 st closing portion 340, the 1 st closing portion 340 closing the 2 nd connection opening 201 when the connection terminal 250 is held in the 1 st connection direction; and a 2 nd closing portion 350, the 2 nd closing portion 350 closing the 1 st connection opening 200 when the connection terminal 250 is held toward the 2 nd connection direction. This can provide a dust-proof effect of suppressing intrusion of dust or the like into the interior of the housing 12 from the connection opening portion where the connection terminal 250 is not provided.

(3) The housing 12 has: 1 st mounting holes 202a, 202b as 1 st positioning portions for mounting holding members 252 that hold the connection terminals 250 toward the 1 st connection direction; and 2 nd mounting holes 203a, 203b as 2 nd positioning portions for mounting the holding member 252 holding the connection terminal 250 toward the 2 nd connection direction. The 1 st mounting holes 202a, 202b and the 2 nd mounting holes 203a, 203b are provided at different positions on the bottom surface 121a within the housing 12. Thus, a power cable or the like connected to an external device can be connected to the imaging apparatus 10 from any one of the 1 st connection direction and the 2 nd connection direction different from each other. Therefore, the degree of freedom in the posture when the imaging device 10 is arranged is increased as compared with a case of a structure in which the power cable or the like is connected from only one direction, and the number of places that can be used as the arrangement place of the imaging device 10 can be increased.

While various embodiments and modifications have been described above, the present invention is not limited to these. Other aspects that are conceivable within the scope of the technical idea of the present invention are also included in the scope of the present invention.

In the above-described embodiment, the imaging device 10 has a structure in which the incidence of the object light to the lens 111 is controlled by the movement of the blade 13 in the 1 st direction. However, the imaging device 10 is not limited to this example, and the actuator 15 of the blade 13 and the blade driving mechanism 14 may not be provided. That is, as shown in the external perspective view of fig. 9, the lens 111 of the imaging device 10 may be always exposed to the outside from the top plate 122 of the housing 12. In this case, the imaging device 10 may have the connector 25 described in the embodiment.

In the above embodiment, the description has been made of the case where the 1 st connection opening 200 is formed in the bottom surface 121a of the rear case 121 and the 2 nd connection opening 201 is formed in the side wall plate 121d of the rear case 121, but the present invention is not limited thereto. One of the 1 st connection opening 200 and the 2 nd connection opening 201 may be formed in the top plate 122 of the housing 12, or the 1 st connection opening 200 and the 2 nd connection opening 201 may be formed in different side wall plates of the rear case 121.

The holding member 252 is not limited to a member that holds the connection terminal 250 in one of the 1 st connection direction and the 2 nd connection direction, that is, the holding member 252 is not limited to have the 1 st holding surface 320 and the 2 nd holding surface 330. The holding member 252 may hold the connection terminal 250 in any one of 3 or more different connection directions, that is, the holding member 252 may have 3 or more holding surfaces for holding the connection terminal 250. For example, in the case where the connection terminal 250 is held in the 3 rd connection direction different from the 1 st connection direction and the 2 nd connection direction, the holding member 252 has the 3 rd holding surface in addition to the 1 st holding surface 320 and the 2 nd holding surface 330. In this case, the 3 rd connection opening may be formed in the case 12. This can increase the direction in which the connection to a power cable or the like connected to an external device is possible. Therefore, the degree of freedom in the posture when the imaging device 10 is arranged is increased, and the number of places that can be used as the arrangement place of the imaging device 10 can be increased.
