ABSTRACT:
A self-developing or instant camera of the type which receives a collapsible cassette containing a plurality of film units arranged in stacked relationship. Transporting means is provided for moving successive exposed film units from the cassette and transporting each of them to a storage chamber beneath the collapsible cassette. During transportation from an exposure position to the storage chamber, each film unit is processed to initiate the formation of a visible image. Springs beneath the cassette bias a lower section of the cassette upwardly relative to an upper section as the successive exposed film units are removed from the cassette and moved beneath the cassette thereby preventing an increased spring pressure on the stack of exposed film units and utilizing the volume gained by the collapsing cassette to accomodate the stack of exposed film units.
