ABSTRACT:
A film feeder/winder is capable of winding films compactly, feeding films backward and keeping films damage-free. A plurality of films wound in a magazine case are fed one by one into a film guide. The film guide is partially openable, so that a film being fed backward can be looped by protruding from the film guide. Films are fed into a scanner/exposure unit for scanning and printing. After printing, films are fed into another magazine case and wound into a roll. It is possible to print any additional films by inserting them into an inlet opening of an extra passage branching from the film feed path. Also, a film being fed backward may be guided into this extra passage until it protrudes from the inlet opening. Both magazine cases have guides and rollers for smoothly winding films around their respective film take-up cores.
