ABSTRACT:
A method of disengaging an anti-backup pawl from a film winding thumbwheel to permit an unexposed filmstrip to be prewound from a film cartridge during original manufacture or recycling of a one-time-use camera has the steps of: depressing a movable free end of the anti-backup pawl to pivot the anti-backup pawl at a fulcrum support between the free end and a movable opposite end of the anti-backup pawl that engages the film winding thumbwheel, in order to disengage the opposite end from the film winding thumbwheel; and holding the free end depressed to maintain the opposite end disengaged from the film winding thumbwheel, in order to permit the film winding thumbwheel to be rotated in engagement with a film spool in the film cartridge when the unexposed filmstrip is prewound from the film cartridge.
