Abstract
A photographic film cartridge assembly includes (1) an opaque casing with an exposure window in one wall and (2) a film unit with photographic film. The film unit has an exposure region and is mounted in the casing for movement in a film advancing direction relative to the casing such that successive portions of the exposure region align with the exposure window. A cover member, including an opaque region, is mounted in the casing between the wall and the film for movement independent of the film unit. The cover member is movable between a closing position, in which said opaque region is aligned with and closes the exposure window, and an opening position, in which said opaque region is out of alignment with and opens the exposure window. Means, associated with the film unit and the cover member are provided for inhibiting movement of the film unit in the film advancing direction when the cover member is in its exposure window closing position. The movement inhibiting means are disabled when the cover member is in its exposure window opening position.
