ABSTRACT:
A one-time-use camera comprising a film cassette having a light lock pivoted open to permit film movement into the cassette interior and pivoted closed to prevent ambient light from entering the cassette interior and a locking pawl movable into engagement with the light lock when the light lock is closed to secure the light lock closed and movable out of engagement with the light lock when the light lock is closed to permit the light lock to be pivoted open, is characterized in that a driver is moveable in engagement with the light lock to pivot the light lock closed to allow the locking pawl to move into engagement with the light lock and has a void which prevents the driver from moving the locking pawl out of engagement with the light lock, whereby the driver can be pushed against the film cassette to push the film cassette out of the camera without any possibility of the driver being moved in engagement with the light lock to pivot the light lock open.
