Abstract
There is disclosed an improved photographic apparatus of the self-developing type and method of operation which includes a film assemblage. The camera includes a housing assembly; strip of photographic film; a strip of self-developing photosensitive film; a foldable strip of carrier sheet material; a mechanism for taking up the photosensitive film strip past an exposure station for exposure thereof and for storage of the exposed photosensitive film strip. An advancing mechanism is provided for advancing the exposed photosensitive film strip from the taking up mechanism and the carrier strip through an exit. Provision is made for a mechanism which is operable for dispensing processing fluid between the exposed film strip and the sheet; and, a pressure applying mechanism is operable for superimposing the photosensitive film relative to the carrier sheet following dispensing of the fluid between the film and sheet for distributing the fluid over preselected portions of the exposed photosensitive film to form an integral photographic film strip in response to the advancing mechanism withdrawing the strip and the sheet through the pressure applying mechanism and the exit.
