In other words, conventionally, the center of gravity of the video camera is balanced on the camera platform by detachably mounting both of the mounting portions to the camera stand located at two positions before and after the shoulder pad on the camera platform. If only one of the two mounting portions before and after the mounting portion is mounted on the camera platform, the video camera cannot be balanced. Therefore, the head also needs to be enlarged so as to match the span of the two mounting portions before and after the head. In addition, the operation of attaching and detaching the two mounting portions having a large span to and from the front and back was also inconvenient.

[0004] Conventionally, the mounting portion to the camera stand is located at the bottom of the camera body and at two places before and after the shoulder pad. Therefore, when the cameraman carries the video camera on his / her shoulder or when the video camera is held by the cameraman. When placed on the head and performing high angle shooting, the metal edge etc. constituting the rear mounting part of the two front and rear mounting parts hit the shoulder and head of the photographer, There was also the danger of an unexpected big injury.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problem, and can reduce the size and weight of a video camera and a camera stand. It is another object of the present invention to provide a device that can be easily detachably attached.

[0006]

In order to achieve the above object, a video camera according to the present invention is provided with a mounting portion to a camera stand at one position on the bottom of the camera body near the center of gravity on the camera body. It is arranged.

In the video camera of the present invention constructed as described above, the mounting portion for the camera stand, which is disposed at one position on the bottom of the camera body, is detachably mounted on the camera stand head. By placing the center of gravity of the video camera on the table, the video camera can be stably mounted on the camera platform.

"Structural Features of Video Camera 1"
The structural features of the video camera 1 will be described.
First, as shown in FIGS. 4 and 5, front and rear end 2a of the camera body 2, to form a height difference H ₁ between 2b, by the formation of the camera body 2 substantially 1/4 circular ring shape, this while reducing configure longitudinal length L ₁ of the camera body 1, it is possible to increase the effective length L ₃ to the rear end face 2d from the front end face 2c of the camera body 1. Therefore, although the video camera 1 is small and lightweight, the camera body 2
The image pickup device, the optical disk device 5, and a plurality of circuit boards and the like can be accommodated with a sufficient space inside.

Next, as shown in FIGS. 4 and 5, the shoulder pad 10 is formed in a substantially 1/4 arc shape.
Its front and rear ends 10a, to the formation of the height difference H ₂ between 10b, and shoulder pads 1 of the optical axis F of the imaging lens 7
By that low as step H ₃ from the rear end 10b is uppermost position of 0, as shown in FIG. 1, the video camera 1
Is carried on, for example, the right shoulder RS of the photographer CM, the shoulder pad 10 is made to follow the rounded RSC of the right shoulder RS of the photographer CM, so that the shoulder pad 10 is positioned at a position closer to the front side of the right shoulder RS by approximately 90 degrees θ _5. It is possible to apply the grip 8 stably at a relatively low position while the right hand RH is extremely naturally bent into a V-shape in a small angle range of. it can. Therefore,
The grip 8 can be naturally moved up and down with the right hand RH without difficulty, and the up and down movement of the right hand RH causes the shoulder pad 10 having a substantially 1/4 arc shape to move in the direction of the arrow a along the roundness of the right shoulder RS. The video camera 1 can be smoothly rotated in the direction of the arrow a (vertical direction) by sliding the video camera 1 smoothly. Therefore, the angle θ ₃ of the imaging lens 7 of the video camera 1 is changed up and down. Can be performed very easily, and the fatigue of the photographer CM can be reduced.
Further, as shown in FIG. 13, the shoulder pad 10 formed in a substantially quarter-arc shape allows the video camera 1 to be mounted on the head HD of the cameraman CM for photographing, as shown in FIG. Easy to stabilize on head HD and head H

Therefore, the pan / tilt operation of the video camera 1 by the camera platform 54 can be performed stably. By providing the attachment portion 14 at only one location, the size and weight of the video camera 1 can be reduced, and the operation of attaching and detaching the attachment portion 14 to and from the camera platform 54 can also be performed. Easy to do. In addition, since the front and rear span of the camera platform 54 can be reduced in accordance with the small front and rear length L1 of the _one mounting portion 14, the overall size and weight of the camera stand 51 can be reduced by reducing the size and weight of the camera platform 54. Therefore, the transportation and storage of the camera stand 51 are facilitated.

Since the mounting portion 14 is arranged on the bottom surface 2e of the camera body 2 between the imaging lens 7 and the shoulder pad 10, as shown in FIG. 1, FIG. 2 and FIG.
When the video camera 1 is carried on the right shoulder RS of the cameraman CM, or as shown in FIGS.
