Abstract
The present invention relates to a barrier member slidably movable along the surface of a camera to a closing position for covering a lens barrel of a camera body and to an opening position for letting the lens barrel be exposed. The camera includes a pressing member for pressing the barrier member from the side of the camera body, and regulating the slide movement of the barrier member in the closing and opening positions. In the camera of the present invention, the barrier member is provided with a guide member abutting on the pressing member at a plurality of points with the center of the pressing member being interposed therebetween in a direction along the surface of the camera and in a direction orthogonal to a slide moving direction of the barrier member, thereby eliminating a backlash of the barrier member.
