ABSTRACT:
A claw and scotch yoke mechanism operatively interconnects a pivotable camera cover door and a rotatable film take-up spool. As the cover door is moved from its closed position to its opened position to provide access to the camera interior, the claw and yoke cooperate to orient a film capturing member provided on the take-up spool in a position allowing easy attachment of a film strip leader to the take-up spool. As the cover door is moved from its open position to its closed position in preparation for camera operation, the claw and yoke mechanism again cooperate to rotate the take-up spool in a film advancing direction to absorb any slack in the film.
