ABSTRACT:
Photographic apparatus for use with film units of the self-developing type. The apparatus includes an elongate member having five extensions which perform a plurality of functions as the elongate member is manually moved between first and second positions. During the movement of the elongate member from the first to the second position, two of the extensions cooperate with a latch to prevent premature movement of the elongate member back into the first position while a third extension engages an exposed film unit and advances it into the bite of a pair of pressure applying rollers. During the movement of the film unit, a fourth extension closes an electrical switch thereby enabling the camera's motor to drive one of the rollers while the fifth extension indexes a film counter.
