DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for an operation member of a camera and an exterior structure.

[0002]

2. Description of the Related Art In a conventional general camera structure, a camera cover as an exterior body for covering a camera built-in portion is mounted. The camera cover may be provided with a release switch with operation buttons, or may be provided with only a release operation button. In the former case, it is necessary to connect the connector of the release switch to the camera-side electric board when the camera cover is mounted. In the latter case, a release switch (contact point) is disposed on the camera-side frame, and the release operation button can be operated by attaching the camera cover.

[0003]

Among the above-mentioned conventional cameras in which a release switch with an operation button is provided on the camera cover, it is necessary to insert a connector of the release switch immediately before mounting the camera cover. . Therefore, the assemblability was poor. Also, it has been difficult to perform an operation test or the like of the release switch without the camera cover attached.

Further, among the above-mentioned conventional cameras, only the release operation button is provided on the camera cover, so that there is no connector connection work when the camera cover is mounted. However, the distance between the release operation button and the contact portion of the release switch is not stable, and the stroke of the operation button until the switch is turned on is different, which may cause a problem in operability.

Further, since the release button mounting holes of the camera covers of the two types of cameras described above are holes that intersect with the direction in which the molding die of the camera cover is removed, the molding die is a slide die. The type structure becomes complicated.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and has a camera having an operation member support structure that is easy to assemble and a simple mold structure for molding a camera exterior body. The purpose is to provide.

[0007]

The switch mounting portion is formed with a wall portion surrounding the release switch so that movement of the release button in the pressing direction is allowed, and when mounting the front cover and the rear cover, The wall is sandwiched by the opening formed by the front cover and the rear cover.

According to a second aspect of the present invention, in the camera according to the first aspect, a circuit board electrically connected to the release switch is mounted on the frame.

According to a third aspect of the present invention, in the camera according to the first or second aspect, the release button includes an elastic member for urging the release button in a direction protruding from the opening. The release button unit is unitized as a release button unit by a restricting member that restricts movement of the release button in the protruding direction by the elastic member, and the release button unit is locked to the switch mounting portion by locking means. .
