Abstract
Abstract A flat still camera wherein a hollow section of the housing is reciprocable relative to the main section to thereby actuate the shutter and/or the film transporting mechanism. When the hollow section is moved to an extended position in which it exposes the lens and the view finder, the two sections define a slot into which a careless user is likely to introduce a finger, an eyelash or an eyelid while holding the camera in front of his eye and while moving the two sections with respect to each other. The rear end of the slot is closed by a portion of a door which is pivotably mounted on the main section and can be opened to afford access to the film chamber. Alternatively, the slot can be overlapped by a panel which is rigid with the main section or with the hollow section of the housing.
