Claims

[Claims for Utility Model Registration] An engaging portion is provided in the camera body, an engaged portion is provided in the lens barrel, and the lens barrel is moved between a non-engaging position and an engaging position with respect to the camera body. A camera having a locking mechanism which is freely disposed so that the lens barrel is removed from the camera body in a non-engaged position, and is attached to the camera body in an engaged position and locks the lens barrel when attached. In the lens barrel attaching/detaching device, the arm part rotatably supports the locking mechanism at one end on the camera body, and rotates around the arm part as a fulcrum between a locking position and an unlocking position;
A locking member that follows the rotational movement of the arm portion, prevents movement of the lens barrel at the locked position, and allows movement of the lens barrel at the unlocked position, and an urging member that urges the arm portion toward the locked position. force means and
A lens barrel attaching/detaching device for a camera, characterized in that it comprises an operating section capable of rotating the arm section from a locking position to an unlocking position against the urging force of the urging means.
