ABSTRACT:
A subassembly for a one-time-use camera comprises a main body part that has a film take-up chamber adapted to receive a film spool and a film supply chamber for an unexposed film roll, a film winding thumbwheel supported for winding rotation in engagement with the film spool to similarly rotate the film spool to take up an exposed filmstrip, and an anti-backup pawl normally engaging the thumbwheel to prevent unwinding rotation of the thumbwheel and disengageable from the thumbwheel to allow unwinding rotation of the thumbwheel to permit the film spool to be similarly rotated to unwind a fresh unexposed filmstrip from the film spool to form the unexposed film roll. The film take-up chamber is configured to allow the film spool to be received in the film take-up chamber in a film unwinding position for unwinding rotation of the film spool and to be in a different film winding position for winding rotation of the film spool. An actuator is movable to disengage the anti-backup pawl from the thumbwheel, and is located to bc moved to disengage the anti-backup pawl from the thumbwheel in response to the film spool being received in the film take-up chamber in the film unwinding position and not when the film spool is in the film take-up chamber in the film winding position.
