PROCESSING STATION MISSINSERTION PREVENTIVE MECHANISM OF IMAGE FORMING DEVICE

摘要

PURPOSE:To prevent mis-insertion of charger or the like, by providing an opening capable of detaching or attaching the charger or the like to a rotary photoreceptor and mis-insertion preventive lid, in an image forming device having a processing station such as charger disposed within the rotary photoreceptor. CONSTITUTION:An opening part 5 is formed in the near side flange 4 of a screen drum 1. This opening part 5 is intended to detach or attach the processing station of a charger 3, and the charger 3 is inserted by being quided by a quide 6 through this opening part 5. the opening part 5 is always controlled to be stopped in the vicinity of the insert inlet of the charger 3. Next, when the charger 3 is pushed to the far side of the opening part 5, a mis-insertion preventive lid 11 is fit into said opening part 5 by fingertip. At this time, the mis-insertion preventive lid 11 is directed to the inside of screen drum and is elastically deformed, so that the charger 3 is pushed in to the specified position correctly. Thus, mis-insertion of the charger or the like may be prevented.
