Abstract: A photocopy machine is of the type which utilizes a reusable photoconductor and which electrostatically makes copies on plain paper. The drum supports a photoconductor of undeterminate length around the peripheral surface of the drum and includes a supply spool of excess photoconductor mounted within the drum and a take up spool for used photoconductor also mounted within the drum so that the portion of photoconductor positioned around the drum can be periodically replaced. A portion of the drum surface is collapsible and supporting structure is provided at the location where the drum surface collapses to support the photoconductor in a flat plane to permit full frame, flash exposure of the photoconductor.

Abstract: An apparatus for making photocopies is disclosed with a photoconductor belt adapted to move around a roller assembly with a cartridge which contains belt replacement segments. The roller assembly meshes with the cartridge to enable rapid continuous movement of the photoconductor which passes a flat region where the belt receives a flash exposure of an object. A mechanism and method for continually replacing the photoconductor belt with incremental fresh segments from the cartridge is described to provide gradual replacement thereof with a long effective usable lifetime for the photoconductor belt and cartridge assembly.
