Abstract

A photographic camera has a housing the front wall of which is provided with a view finder having an inlet window and with a lens. A manually slidable first cover is movable to and from a position in which it covers the inlet window, and the second cover is movable to and from a new position in which it covers the lens. An arrangement is provided which links the covers for joint movement so that when the view finder cover moves to a position in which it uncovers the view finder the lens cover automatically also moves to a position to which it uncovers the lens, and vice versa.
