Abstract

Abstract A cartridge of self-processing photographic film includes first and second supply chambers, one each for film and second or process elements, and a take-up chamber for collecting and storing processing waste material disposable with the cartridge. In a preferred form, film is supplied in the cartridge from a single roll and is advanced therefrom to a first position for exposure, then to a second position for processing, and finally to a take-up mechanism for winding the film back into a roll. Individual second elements are supplied as sheets in stacked relation in a second chamber, behind the film processing chamber, and are superposed or registered one at a time with the film for processing. After processing, the second sheet, with the image received thereon, is stripped from the film automatically and transported to the cartridge exterior at the same time the film is wound into the take-up chamber. Alternatively, the cartridge back may be opened for manual stripping of the finished print.
