Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video camera device, and more particularly to a video camera device in which a lens portion and a viewfinder portion are connected to a main body of the video camera.

[0002]

2. Description of the Related Art In a video camera device for broadcasting,
It is common to provide a large viewfinder separately from the video camera body. Also, in a device that requires such a large viewfinder,
Since a high-quality image is taken, a very large lens part is used, and the lens itself is often replaceable.

In addition, a video camera has recently been developed which obtains an image at a higher density (higher speed) than a normal television signal in the time direction. In this type of video camera, it is necessary to dispose a shutter unit that can operate at high speed between the lens and the camera body. Further, in normal operation, this shutter unit is unnecessary, so it must be detachable.

[0004]

However, when such a large lens is used, the weight of the entire lens becomes large because the weight of the camera body is being reduced. Therefore, there arises a problem that the optical axis is bent due to the weight of the lens at the joint between the lens and the camera body.

This problem is that when the detachable coupling portion is increased and the distance from the camera body to the lens tip is increased, the shutter unit as described above is sometimes provided between the lens and the camera body. It is remarkable.

To solve this problem, the lens part may be supported. However, when the lens part is removable, it is expected that this support member will hinder the mounting / removing operation, and the supporting part is simply supported. No separate part can be provided. Also,
If the support section is provided alone in this way, the lens section provided at the front, the camera body, and the viewfinder provided at the rear are all supported, and the weight of the apparatus as a whole becomes extremely heavy. The size itself will increase.

The present invention has been made under such a background, and it is possible to effectively prevent the bending of the optical axis without increasing the size of the entire apparatus and preventing the weight reduction. It is an object of the present invention to provide a video camera device capable of doing the above.

[0008]

[Means for Solving the Problems] Under such a purpose,
In the video camera device of the present invention, the video camera main body, the lens portion coupled to the camera main body, the coupling portion for coupling the lens and the camera main body, and the image captured by the camera main body It has a viewfinder section capable of displaying an image and a support member which fixes the viewfinder section to the rear of the camera body and extends from the front to the rear of the camera body to support the coupling section. It was composed.

[0009]

As described above, since the main body, the viewfinder and the coupling portion are supported by the single supporting member, the supporting member has a simpler structure and can be downsized as compared with the case of supporting the lens.
Further, by supporting the coupling portion, it is possible to effectively prevent the bending of the optical axis.
