Photoreceptor drum for use in electrophotographic copying apparatus

摘要

A photoreceptor drum for use in an electrophotographic copying apparatus which includes a sheet-like photoreceptor stored in roll form on a supply roll housed within the drum and led therefrom around the outer periphery of the drum through a slot axially formed in the drum surface so as to be wound onto a takeup roll also housed within the drum for enabling the photoreceptor on the drum to be replaced when wound onto the takeup roll. The drum is provided with a covering member for the slot which can be raised from the photoreceptor surface during replacement of the photoreceptor, and the raising of the covering member is associated with releasing of locking of the supply roll.
