Abstract
A camera body includes a photographing lens. A barrier is supported on the camera body so as to be movable between a cover position covering the photographing lens and a retreat position retreated from the cover position in a first direction substantially parallel to an optical axis of the photographing lens and a second direction substantially perpendicular to the first direction. A rail mechanism is provided to guide relative movement between the camera body and the barrier in the first and the second directions of the barrier. The rail mechanism comprises a first slide projection, a second slide projection, a first cam portion and a second cam portion. The first slide projection has a predetermined projecting length and guides movement of the barrier. The second slide projection has a projecting length longer than the first slide projection and guides movement of the barrier. The first cam portion is slidably engaged with the first and the second slide projections and guides movement of the barrier in the second direction. The second cam portion, branched from the first cam means and slidably engaged with only the first slide projection, guides movement of the barrier in the first direction.
