ABSTRACT:
A self-processing camera is adapted to receive a film magazine containing a plurality of film units mounted in a line upon an elongated leader paper and equally spaced therealong. Each of the film units includes an image recording unit consisting of a photosensitive sheet overlying an image receiving sheet and separable therefrom, and a rupturable portion, containing processing fluid, disposed at one side of the image recording unit. The leader paper is folded to dispose the film units in a superposed stack within the film magazine and the latter has a take-up reel to which is secured one end of the leader paper and is adapted to wind thereon a film unit excluding the image recording unit. After exposure of the foremost film unit, the leader paper is wound upon the take-up reel, drawing the exposed film unit between pressure rollers which rupture the portion containing processing fluid and distribute the latter over the exposed film unit to develop the same, whereafter the film unit is separated from the leader paper and discharged from the camera. The camera includes a rotating member which automatically rotates the take-up reel of the magazine at a controlled rate in response to the termination of exposure and also insures that the take-up reel is rotated to a precise extent sufficient to wind the leader paper thereon by a length corresponding to the distance between the leading edge of one film unit and the leading edge of the next film unit.
