ABSTRACT:
A windup reel is formed at a step reel which has a small diameter section and a large diameter section. The large diameter section is formed in such a direction as to press a lower edge of photographic film against a guide pin. When a leader section of transported photographic film is wound on the windup reel, the leader section tries to fit the surface of the large diameter section. For this reason, the force is applied to the photographic film so that the photographic film can move toward the large diameter section. The photographic film moves toward the guide pin, and the edge of the photographic film is pressed against the guide pin. Thereby, the photographic film is transported along the guide pin.
