ABSTRACT:
A film assemblage for use with a camera of the self-developing type having a pair of superposed rollers for rupturing a container of processing liquid attached to an exposed film unit and spreading its contents across a photosensitive layer thereof while simultaneously advancing the exposed film unit toward the exterior of the camera. The assemblage includes a film cassette for housing a plurality of film units and an imbibition chamber which originally functions as a dark slide or cover for protecting the film units from exposure during its insertion into the camera. The imbibition chamber includes first and second opposed open ends and is tethered to the film cassette such that after the assemblage has been loaded into the camera and the imbibition chamber or dark slide has been removed from the film cassette and advanced toward the exterior of the camera by the superposed rollers, the tether runs out so as to retain the imbibition chamber in a position wherein its second open end is located exteriorly of the camera and its first open end is located just outboard of the superposed rollers. In such a position, the imbibition chamber is adapted to receive an exposed film unit via the first open end as it emerges from between the superposed rollers and maintain its exposed photosensitive layer in a substantially light free environment until the processing of the film unit by the liquid has reached a state wherein it may be removed from the imibibition chamber via the second opening without being subject to further exposure by the ambient light.
