Abstract
Apparatus for advancing individual photographic film units from a stack of the same and moving them to the exterior of a cassette. The film units, which are of the instant or self-developing type, each include a leading end having a rupturable container of processing liquid thereon and a relatively thin trailing end, such trailing ends being located in very close proximity when the film units are properly stacked in the cassette. The advancing apparatus includes first and second members adapted for movement toward the trailing ends of the film units which results in the first member wedging itself between an endmost film unit and an adjacent film unit in the stack in a manner which depresses the trailing end of the adjacent film unit out of the path of movement of the second member while simultaneously supporting the endmost film unit's trailing end in such path for subsequent engagement by the second member.
