Abstract
A nip roller is provided to interpose a leading portion of a photo film between the nip roller and a core. The nip roller performs a circular motion along the periphery of the core in synchronism with the rotation of the core. The circular motion is performed by first to third motors until the leading portion of the photo film makes one revolution around the core and is just about to be wound in a stack condition. A conveyance slip is hardly caused between the photo film and the core, and between the photo film and the nip roller.
