ABSTRACT:
A hand-held camera adapted for use with a film cassette containing at least one film unit and a separate overlying opaque cover sheet which is adapted to protect the film unit from exposure during the loading of the cassette into the camera. The camera includes a film cassette positioning member drivingly engageable with a film advancing apparatus and with a pair of juxtaposed rollers, and a manually operable member connected with the film cassette positioning member. Upon actuation of the manually operable member, the film cassette positioning member is moved to thereby reposition the film cassette within the camera while simultaneously driving the film advancing apparatus in a manner which moves the opaque cover sheet partially out of the film cassette and into the bite of the rollers, which in turn continue its movement away from the film cassette thereby preparing the film unit for exposure.
