Film cartridge assembly

摘要

A photographic cartridge assembly includes (1) an opaque casing with an exposure window in its front wall and (2) a film unit rotatably mounted in the casing such that successive film portions can be aligned with the exposure window. An opaque cover member is mounted in the casing between the front wall and the film unit for oscillatory movement about an axis, both parallel to the axis of rotation of the film unit and between the exposure window and the axis of rotation of the film unit, into and out of alignment with the exposure window.
