Abstract

A photographic roll film camera has a film supply chamber, a spoolless film take-up chamber, a transporting element for transporting the film between these chambers, and a film roll-forming element including a part of the wall of the take-up chamber formed in correspondence to a whole film roll, and a spring-biased guiding lever extending into the take-up chamber and bounding together with the wall a small space for forming a first coil of the film roll so that the initial portion of the film is guided into the small space by the guiding lever and thereafter with increase of the diameter of the film roll during winding of subsequent coils, the guiding lever turns and space for formation of the film roll expands.
