Is shown. FIG. 3 is an example of a 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 another device to shoot at a low angle. Is shown.

  The gimbal 300 includes a first support 302, a second support 304, and a third support 306. The first support unit 302 rotatably supports the imaging device 100 about a first axis (X axis). The first support unit 302 rotatably supports the imaging device 100 about a first axis along the imaging surface of the imaging device 100.

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

The second rotating unit 303 is a relatively heavy member including an actuator. If such a member is located above, there is a possibility that the burden of supporting the imaging device 100 by the gimbal 300 will increase. And the gimbal 300 can maintain the attitude of the imaging device 100 more stably.

  Therefore, according to the imaging system 10 of 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 intersecting the bottom surface 432. The connecting portion 401 may be provided on a front surface 433 perpendicular to the bottom surface 432. The front surface 433 that intersects the bottom surface 432 may be a surface that forms an angle of 110 degrees or less, 100 degrees or less, or 90 degrees or less, and 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, even if the imaging system 10 is changed from the posture shown in FIG. 2 to the posture shown in FIG. (That is, the lower side in the vertical direction). Therefore, the burden of supporting the imaging device 100 by the gimbal 300 is reduced as compared with the case where the connecting portion 401 is provided on the ceiling surface 437 of the main body 400. Then, the posture of the imaging device 100 supported by the gimbal 300 can be stabilized.

  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 on the housing 430 via the hinge 451. The hinge 451 may be provided on the rear surface 436.

  The main body 400 may include an operation unit for operating 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. The main body 400 may include, for example, an operation button 415 for operating the imaging system 10 on the first side surface 434 of the housing 430. The handle unit 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 device 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 detachably from the housing 430.

  FIG. 6 illustrates an example of the inside of the housing 430. The main body 400 includes a discharge mechanism 420 in the housing 430. In the housing 430, a control board 416 for controlling the imaging device 100 and the gimbal 300, a memory 412, and a battery 414 may be arranged.

  The discharge mechanism 420 discharges heat generated in the control board 416 to the outside of the housing 430. The rear surface 436 of the housing 430 has an air inlet 421 for taking in fluid such as outside air into the housing 430. The intake port 421 is disposed on a rear surface 436 of the housing 430 opposite to the surface on which the gimbal 300 is installed. The discharge mechanism 420 has an exhaust port 423 for discharging a fluid to the outside of the housing 430 on an inclined surface 438 opposite to the rear surface 436 of the housing 430. The inclined surface 438 is an example of a surface of the housing 430 on the side where the gimbal 300 is installed. The discharge mechanism 420 has an air passage 422 that connects the intake port 421 and the exhaust port 423. The discharge mechanism 420 has a fan 424 near the exhaust port 423. The discharge mechanism 420 may have a plurality of fins in the ventilation path 422 that guide the flow of the fluid from the inlet 421 to the outlet 423. The fluid taken into the housing 430 from the intake port 421 passes through the ventilation path 422 and is discharged from the exhaust port 423 as shown by an arrow 500. The heat generated in the control board 416 is transmitted into the ventilation path 422, and is discharged from the exhaust port 423 to the outside of the housing 430 by the fluid passing through the ventilation path 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, and has a large processing load and a large amount of heat generation. The heat generated by the control board 416 may affect the memory 412 or the battery 414.

  Therefore, in the imaging system 10 according to the present embodiment, as illustrated in FIG. 7, the ejection mechanism 420 includes the first space 471 in the housing 430 where the control board 416 is disposed and the data processed by the control board 416. And a second space 472 in the housing 430 in which at least one of the battery 414 that supplies power to the control board 416 and the memory 412 that stores the power is provided. The discharge mechanism 420 may be provided in the third space 473 between the first space 471 and the second space 472. As shown by the arrow 500, the fluid is taken into the discharge mechanism 420, and discharges the heat generated in the control board 416 to the outside. Here, the wall 425 of the ventilation path 422 that contacts the first space 471 may be made of a material having a higher thermal conductivity than the wall 426 of the ventilation path 422 that contacts the second space 472. For example, the wall 425 that defines the ventilation path 422 may be made of an aluminum material having a high thermal conductivity. The wall 426 that defines the air passage 422 may be made of resin, ceramic, or the like that functions as a heat insulating material having a lower thermal conductivity than aluminum. By forming the wall of the air passage 422 in contact with the second space 472 with a material having low thermal conductivity, the heat generated in the control board 416 is transmitted to the second space 472 via the air passage 422 and the memory 412 or The battery 414 can be prevented from being affected.

  8 and 9 show an example of the state of the flow of the 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 arranged with the connecting portion 401 to which the gimbal 300 is connected. The discharge mechanism 420 may have a plurality of fins 427 that guide the flow of the fluid taken in from the intake port 421 through the exhaust port 423 via the pair of fans 424. 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, fluid is taken into the air passage 422 from the intake port 421 from the direction shown by the arrow 501, and flows in the direction shown by the arrow 502 from the exhaust port 423 to the direction shown by the arrow 503. Is discharged. Thus, heat generated in the control board 416 can be efficiently discharged to the outside of the housing 430. By providing the exhaust port 423 on the surface of the housing 430 on the side where the gimbal 300 is installed, it is possible to prevent the heated fluid from being discharged toward the user.
