A one-time-use camera having a film take-up chamber, a film spool rotatable in the film take-up chamber, a film winding thumbwheel supported for winding rotation in coaxial engagement with the film spool to similarly rotate the film spool to take up an exposed filmstrip, and an anti-backup pawl for preventing unwinding rotation of the thumbwheel, is characterized in that the anti-backup pawl engages said film spool to prevent unwinding rotation of the film spool, in order to prevent unwinding rotation of the thumbwheel. Preferably, a film door closes the film take-up chamber, and the anti-backup pawl is supported on the film door to engage the film spool.
