ABSTRACT:
A one-time-use camera which comprises a first part including a film winding thumbwheel rotatably supported for winding and unwinding rotation, and a second part assembled to the first part and including a resilient anti-backup pawl for engaging the thumbwheel to prevent unwinding rotation of the thumbwheel, is characterized in that the first part has a deflector arranged to deflect the anti-backup pawl to prevent the anti-backup pawl from engaging the thumbwheel during assembly of the first part to the second part and to allow the anti-backup pawl to engage the thumbwheel when the first part is assembled to the second part. Preferably, the deflector has an inclined portion that flexes the anti-backup pawl out of reach of the film winding thumbwheel to prevent engagement of the anti-backup pawl with the thumbwheel during assembly of the first part to the second part and an undercut that receives the anti-backup pawl to permit return of the anti-backup to within reach of the thumbwheel to allow the anti-backup pawl to engage the thumbwheel when the first part is assembled to the second part.
