Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of an electronic camera having an image pickup device for photographing and capable of transmitting or receiving signals with an external device.

[0002]

2. Description of the Related Art In an electronic camera having a CCD which is an image pickup device for photographing, when an external communication connector is arranged at an end of the camera, it is necessary to provide a connector opening for inserting a plug portion of a cable in the camera exterior. is there.

Therefore, in a conventional electronic camera, a connector board on which a connector separated from a main board is mounted is prepared, and this is directly fixed near an opening of a camera exterior. Further, an opening / closing lid is provided near the connector opening to protect the opening from the outside when the connector is not used.

The reason that the connector board is adopted in the above-mentioned conventional electronic camera is that, in the electronic camera, since the CCD is mounted on the main board, the position of the main board in the optical axis direction is determined by the position of the CCD with respect to the optical system. However, if the connector is directly mounted on the main board, the position of the connector is naturally limited, and the desired position is often not obtained. Therefore,
A connector board different from the main board is provided, and the connector board and the main board are connected by a flexible board.

Further, the reason why the connector board is directly fixed to the camera exterior as described above is that it is easy to make the connector coincide with the opening of the camera exterior. This is because if the gap between them becomes large, dust invades the inside, and the aesthetic appearance also worsens.

[0006]

However, when the connector board is directly fixed to the camera exterior as in the above-mentioned conventional electronic camera, the support is unstable when the connector board does not have the exterior, and maintenance and inspection are not performed. It was hard to do. In addition, there was a problem that the operation of the camera could not be checked without the exterior.

Further, since the connector board is directly fixed to the camera exterior, the connector board is attached at the time of assembling the camera exterior, which makes assembly work difficult.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a connector capable of correctly positioning an opening in a camera exterior. An object of the present invention is to provide an electronic camera that can be easily assembled.
