ABSTRACT:
A belt support structure which telescopically movably supports a belt assembly in a photoelectrostatic copying machine. The belt support structure has first guide rails secured at at least two spaced points thereof to a wall or framework of the housing structure for the copying machine, second guide rails respectively telescopically movably mounted on the first guide rails and third guide rails telescopically mounted on the second guide rails. The third guide rails carry the belt assembly for pivotal movement between operative and released positions. When the belt assembly is in the released position outside the housing structure, replacement of the used photoreceptor belt, inspection, repair or cleaning of all operating elements of the copying machine arranged around the photoreceptor within the housing structure can be facilitated.
