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.
