ABSTRACT:
A film winding member and a shutter cocking member are movable as a unit until the shutter is cocked, and then the film winding lever moves by itself. The film winding member is stopped when a film position sensing lever senses a hole in the film indicating the frame position. Means are provided to prevent a shutter release member from being moved until the film has been advanced and the film winding member has been returned to its initial position. The film advancing operation and the shutter cocking operation are accomplished with one stroke of the film winding member.
