Abstract
A photographic camera has a barrier which is disposed between the camera body and a decorative front cover to be movable between a closing position where it covers a taking lens of the camera and an opening position where it opens the taking lens through an opening formed in the front cover. The barrier is provided with an opening which is brought into alignment with the taking lens and the opening in the front cover when the barrier is moved to the opening position and has a smaller diameter than the opening in the front cover. An anti-flare pattern of recessed portions and protruded portions is formed on the outer surface of the barrier around the opening.
