Abstract:
A subassembly for a one-time-use camera comprising 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 engageable with said thumbwheel to prevent unwinding rotation of said thumbwheel and disengageable from said thumbwheel to allow unwinding rotation of the thumbwheel to permit the film spool to be similarly rotated to unwind an exposed filmstrip from the film spool to form the unexposed film roll, is characterized in that:said film take-up chamber is configured to allow the film spool to be received in said 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; andan actuator is movable to disengage said anti-backup pawl from said thumbwheel, and is located to be moved to disengage said anti-backup pawl from said thumbwheel in response to the film spool being received in said film take-up chamber in the film unwinding position and not when the film spool is in said film take-up chamber in the film winding position.
