Abstract: A roll film, which is wound up on a feeder spool with emulsion surface facing inward on the roll, is turned inside out and is drawn from the feeder spool to a first guide roller. The photo film is turned inside out again while being fed through a second guide roller and is wound up on a take-up spool with the emulsion surface facing inward on the roll. On an inner wall of a film magazine facing the second guide roller, a press roller presses the photo film to prevent loosening of the photo film in a film feeding path from the periphery of the second guide roller to the take-up spool.

Abstract: A film back exchangeable camera is provided. The film back exchangeable camera has a camera body and a film back that can be attached to a rear portion of the camera body. The film back exchangeable camera includes a backward protrusion protruding backward from a film back attaching surface and covering a top surface of the film back. The camera also includes at least one operation member provided on the backward protrusion and a grip portion protruding backward from the film back attaching surface and covering one side surface of the film back.

Abstract: The invention relates to an interchangeable miniature-film magazine having a receiver for a film cassette, a sprocket for the film advancement, a winding drum, and a shutter for closing the film gate provided in the magazine housing. In order to provide as compact a design as possible, the sprocket can be located immediately behind the cassette outlet, at a clear distance which is smaller than the width of the film gate across. The unexposed film, which is previously wound completely onto the winding drum in the prewind operation, with the winding direction of the film on the winding drum being identical to that of the spool body of the film cassette, is guided from the winding drum, arranged closely alongside the film cassette, in a large radius around the film cassette into the plane of the film gate, with a subsequent, nearly 180°-deflection around the sprocket into the cassette outlet.

Abstract: A photographic camera of small, flat design, comprising a body shell, a taking lens, a viewfinder, a film chamber, a film transport apparatus, and a flash device. The body shell is configured parallelepipedally and has on its front side a linear flat guideway in which a lens slide is guided displaceably from a non-operating position into a taking position and for purposes of film transport. For this purpose the body shell is equipped on the back side with a linear flat guideway, and the film chamber is configured as a replaceable film cassette that is displaceably guided in the flat guideway. The film cassette serves to receive a film strip equipped with an edge perforation, and consists of a flat, parallelepipedal housing with an exposure window and a film mouth. There extends in the housing, in the longitudinal direction thereof, a circumferential and continuous film channel which passes by the exposure window and opens into the film mouth.
