Drum for photosensitive material for photocopier - positions reel of material in pivoted segment to form loop around outside of drum

摘要

The photocopier has a rotating drum covered with the photosensitive sheet, as a replaceable fitting, which is removed after a set number of copies. The material is mounted as a reel (4b) inside the drum and is taken in a loop around the outside of the drum and back into the drum to a takeup reel (4a). The reels can be moved to move the material to a fresh area without having to dismantle the equipment. The supply reel is mounted in a segment (12) of the drum, which is swung out of the drum for easier loading and access.
