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.
Claims17
A camera film winding and shutter actuating mechanism, comprising:
- a film take-up spool drive member;
- a shutter cocking member movable with the spool drive member;
- cocking member stop means operatively arranged to prevent movement of the cocking member beyond a shutter cocking position;
- cocking member biasing means releasably connecting the cocking member to the spool drive member so that the cocking member is movable in a film winding direction with the spool drive member up to the shutter cocking position and the spool drive member is movable further against the force of the cocking member biasing means;
- film frame position sensing means operative to sense a film frame condition and move from a sensing position to a film frame position in response thereto;
- and
- spool drive member stop means actuated by the position sensing means and operative to stop movement of the spool drive member when the position sensing means senses the film frame condition and moves to the film frame position.
