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.
