Indicates. FIG. 3 shows the positional relationship between the imaging device 100, the gimbal 300, and the main body 400 when the user holds the imaging device 100 in his hand or hangs the imaging device 100 on other equipment and shoots at a low angle, for example. An example is shown.

  The gimbal 300 includes a first support 302, a second support 304, and a third support 306. The first support unit 302 supports the imaging device 100 so as to be rotatable about the first axis (X axis).

  The second support portion 304 supports the first support portion 302 rotatably about the second axis (Y axis). The third support portion 306 supports the second support portion 304 rotatably about the third axis (Z axis). The first support unit 302 includes a first rotation unit 301 that rotates the imaging device 100 around the first axis (X axis) at one end.

The first axis (X axis), the second axis (Y axis), and the third axis (Z axis) may be three axes orthogonal to each other.

  The main body 400 includes a housing 430. The housing 430 is connected to the third support portion 306 of the gimbal 300 and holds the gimbal 300. The housing 430 holds the imaging device 100 outside. The housing 430 holds the imaging device 100 via the gimbal 300 outside. The housing 430 has a bottom surface 432 that contacts the placement surface when the housing 430 is placed.

  Here, as shown in FIG. 4, it is conceivable to provide the connecting portion 401 on the ceiling surface 437 opposite to the bottom surface 432 of the housing 430. When the user tries to shoot at a low angle, the main body 400 can be changed from the posture shown in FIG. 4 to the posture shown in FIG. In this case, when the connecting portion 401 is provided on the ceiling surface 437, as shown in FIG. 5, the second rotating portion 303 of the gimbal 300 is positioned upward (that is, vertically upward). The second rotating unit 303 includes an actuator and is a relatively heavy member. When such a member is positioned above, there is a possibility that the burden of supporting the imaging device 100 by the gimbal 300 increases. Then, the posture of the imaging device 100 supported by the gimbal 300 may become unstable.

  Therefore, according to the imaging system 10 according to the present embodiment, the connecting portion 401 is provided not on the ceiling surface 437 of the main body 400 but on the front surface 433 that intersects the bottom surface 432. The connecting portion 401 may be provided on the front surface 433 perpendicular to the bottom surface 432. The front surface 433 intersecting the bottom surface 432 may be a surface having an angle of 110 degrees or less, 100 degrees or less, or 90 degrees or less, 60 degrees or more, 45 degrees or more, or 30 degrees or more with the bottom surface 432.

  By providing the connecting portion 401 on the front surface 433, when the user tries to shoot at a low angle, the second rotating portion 303 can be moved downward even if the imaging system 10 is changed from the posture shown in FIG. 2 to the posture shown in FIG. (Ie, vertically below). Therefore, compared with the case where the connecting portion 401 is provided on the ceiling surface 437 of the main body 400, the burden of supporting the imaging device 100 by the gimbal 300 is reduced. The gimbal 300 can maintain the posture of the imaging apparatus 100 more stably.

  The main body 400 may further include a handle portion 440 provided on each of the first side surface 434 other than the bottom surface 432 and the front surface 433 opposite to the bottom surface 432 and the second side surface 435 opposite to the first side surface.

The display unit 450 may be provided in the housing 430 through the hinge unit 451. The hinge portion 451 may be provided on the rear surface 436.

  The main body 400 may include an operation unit that operates at least one of the imaging device 100 and the gimbal 300 on a surface other than the front surface 433 and the bottom surface 432 of the housing. For example, the main body 400 may include an operation button 415 for operating the imaging system 10 on the first side surface 434 of the housing 430. The handle portion 440 may have a user interface for operating the imaging system 10.

  The main body 400 may include a memory 412 that records image data captured by the imaging apparatus 100. A mounting portion for mounting the memory 412 may be provided on the first side surface of the housing 430. The main body 400 may include the imaging device 100, the gimbal 300, and a battery 414 that supplies power to the main body 400. The battery 414 may be provided so as to be removable from the housing 430.

  FIG. 6 shows an example of the inside of the housing 430. The main body 400 includes a discharge mechanism 420 in the housing 430. A control board 416 that controls the imaging device 100 and the gimbal 300, a memory 412, and a battery 414 may be disposed in the housing 430.

  The discharge mechanism 420 discharges heat generated by the control board 416 to the outside of the housing 430. The rear surface 436 of the housing 430 has an intake port 421 for taking fluid such as outside air into the housing 430.

The discharge mechanism 420 has an exhaust port 423 that discharges fluid out of the housing 430 on the inclined surface 438 opposite to the rear surface 436 of the housing 430. The inclined surface 438 is an example of a surface on the side where the gimbal 300 of the housing 430 is installed. The discharge mechanism 420 has a ventilation path 422 that allows the intake port 421 and the exhaust port 423 to communicate with each other. The discharge mechanism 420 has a fan 424 in the vicinity of the exhaust port 423. The discharge mechanism 420 may include a plurality of fins that guide the flow of fluid from the intake port 421 to the exhaust port 423 in the air passage 422. The fluid taken into the housing 430 from the intake port 421 is discharged from the exhaust port 423 through the ventilation path 422 as indicated by an arrow 500. Heat generated in the control board 416 is transmitted into the air passage 422 and is discharged from the exhaust port 423 to the outside of the housing 430 by the fluid passing through the air passage 422. Thereby, the control board 416 can be cooled.

  The control board 416 is a main board that controls the imaging device 100, the gimbal 300, and the like, has a heavy processing load, and generates a large amount of heat. Heat generated by the control board 416 may affect the memory 412 or the battery 414.

Between the second space 472 in the housing 430 in which at least one of the memory 412 that stores the power and the battery 414 that supplies power to the control board 416 is disposed. The discharge mechanism 420 may be provided in the third space 473 between the first space 471 and the second space 472. As indicated by an arrow 500, the fluid is taken into the discharge mechanism 420 and the heat generated by the control board 416 is discharged to the outside. Here, the wall 425 in contact with the first space 471 of the air passage 422 may be made of a material having higher thermal conductivity than the wall 426 in contact with the second space 472 of the air passage 422. For example, the wall 425 that defines the air passage 422 may be made of an aluminum material having high thermal conductivity. The wall 426 that defines the air passage 422 may be made of a resin, ceramic, or the like that functions as a heat insulating material having a lower thermal conductivity than an aluminum material. By configuring the wall in contact with the second space 472 of the air passage 422 with a material having low thermal conductivity, heat generated in the control board 416 is transmitted to the second space 472 via the air passage 422, and the memory 412 or It is possible to prevent the battery 414 from being affected.

  8 and 9 show an example of the flow of fluid in the discharge mechanism 420. FIG. The main body 400 may include a pair of fans 424 in the housing 430. The pair of fans 424 may be disposed with the connecting portion 401 to which the gimbal 300 is connected interposed therebetween. The discharge mechanism 420 may include a plurality of fins 427 that guide the flow of fluid taken from the intake port 421 through the pair of fans 424 and discharged from the exhaust port 423. The plurality of fins 427 may be made of the same material as the wall 425 in contact with the first space 471, for example, an aluminum material. When the pair of fans 424 are driven, the fluid is taken into the air passage 422 from the direction of the arrow 501 from the direction indicated by the arrow 501, and the fluid flows from the exhaust port 423 to the direction indicated by the arrow 503 in the flow as indicated by the arrow 502. To be discharged. Thereby, the heat generated in the control board 416 can be efficiently discharged to the outside of the housing 430. Thus, the influence of heat generated in the housing 430 can be suppressed. Further, by providing the exhaust port 423 on the surface of the housing 430 on the side where the gimbal 300 is installed, the heated fluid can be prevented from being discharged toward the user.
