ABSTRACT:
A photographic film cartridge assembly has front and rear opposed walls between which photographic film is movable to align image areas with an exposure window in the front wall. A film support surface is enterable into the cartridge assembly through the exposure window. An opening in the rear wall is aligned with the exposure window, and a pressure plate is retained on the rear wall for movement toward and away from the front wall. Baffle means on the pressure plate and the rear wall form a tortuous light path to prevent light entering the cartridge assembly through the opening from reaching the film.
