摘要： The electrophotographic copying machines are of the type in which a photosensitive drum is removable from the machine, for inspection or other purposes, through an opening formed in a sidewall, which opening is normally covered by a coverplate. Plural cleaning devices which are normally maintained in pressing engagement with the peripheral drum surface, are automatically released from such engagement once the coverplate has been dismounted from the sidewall and also returned to the original position as the coverplate is remounted, thereby preventing damage of the drum as well as a wrong usage of the machine which may be caused by inadvertently failing to reset each cleaning device. The construction is further effective to adjust the respective forces with which the cleaning devices are pressed against the peripheral drum surface and moreover to deenergize a motor or motors, for driving the drum and/or other movable parts, as the cleaning devices are lifted from engagement with the drum surface, thereby permitting an inspection of such movable parts in operation even after the coverplate has been dismounted from the sidewall.
