ABSTRACT:
A camera having an operating mechanism which comprises a body providing a film take-up chamber for containing an initially empty film cartridge, an exposure chamber having an open rear side, and a film supply chamber for containing a roll of film pre-exposed with border images on respective frames to define respective unexposed areas for subsequent photographic exposure. The operating mechanism includes a shutter mechanism, a film-advancing member for advancing the film frame-by-frame from the film supply chamber to the film take-up chamber across the exposure chamber rear side, and a trigger mechanism for operating the shutter mechanism in response to film advancement by the film-advancing member. A movable cover is used between the exposure chamber rear side and the film, which has a see-through portion to reveal the unexposed area for photographic exposure while protecting the border image of each successive frame. An operating lever is used to engage the cover to the film such that the cover is movable by the film, during film advancement, with the see-through portion maintained in accurate alignment with the unexposed area of each successive frame.
