ABSTRACT:
In a roll film camera defining a film track, and having a film-advance distance, provision is made for any bend in the film due to the rerouting thereof over a film rerouting roll, to be rendered harmless by disposing the film rerouting roll at a predetermined distance along the film track from a film inlet edge of a film gate of the camera; the predetermined distance is about equal to the film-advance distance, plus one half the difference between the spacing of the film inlet and outlet edges of the film gate.
