ABSTRACT:
A film assemblage including a cassette, a plurality of film units of the self-developing type, a leader formed from an elongate strip of opaque material and a reel upon which the leader is adapted to be wound as the film units are manually withdrawn from the cassette. The leader is releasably connected to each film unit via a pull tab located near one end of each film unit. When the assemblage is located within a camera, the reel is manually rotated until a portion of the leader is removed from covering relationship with a film unit and the tab of that film unit extends between a pair of rollers to the exterior of the camera. The film unit is then exposed and the tab is manually pulled to draw the exposed film unit between the rollers for processing. Movement of the film unit through the rollers is effective to rotate the reel to thereby wind the leader thereupon until the tab of the next film unit to be exposed protrudes to the exterior of the camera.
