Active light lock coupled restraint and camera

摘要

A film door restraint and camera used with a film door having a tappet movable between latched and unlatched positions, a film cartridge having a filmstrip and an active light lock movable between open and closed states, and a cartridge spool driver movable in first and second directions of rotation to rotate a spool of said cartridge. The film door restraint has a toggle, a rotational member, and a follower. The toggle is coupled to the active light lock and is capable of tripping between an open position, in which the active light lock is open, and a closed position, in which the active light lock is closed. The toggle is tripped by the tappet when the toggle is in the open position and the tappet is moved from the latched position to the unlatched position. The rotational member is joined to the spool driver for rotation with the spool driver. The rotational member defines primary and secondary guideways. The follower has first and second ends and is disposed to travel along the guideways during the rotation of the rotational member. The second end traps the toggle in the open position when the first end is disposed in the primary guideway. The second end frees the toggle to trip when the first end is disposed in the secondary guideway.
