Abstract: A clam-shell type image-forming device such as photocopying or facsimile machine has an upper unit and a lower unit hinged to each other at one side. Access to internal parts, such as the photosensitive member, is gained by unlocking the two units from each other and rotating the upper unit upward. A subframe is included within the upper unit and contains the photosensitive member. When the upper unit is opened, the subframe may be lowered to position the photosensitive member for easy inspection and removal.

Abstract: An electrostatic copying apparatus comprises a housing including a lower housing section and an upper housing section mounted on the lower housing section and capable of swinging to open the lower housing section, a photosensitive drum provided in the upper housing section, a support mechanism attached to the upper housing section for supporting the photosensitive drum to allow the drum to be rotated and detached, a guide mechanism attached to the lower housing section for guiding the photosensitive drum to one end of the lower housing section after the drum has been detached from the supporting mechanism, and at least one peripheral device provided within the upper housing section, put in contact with the photosensitive drum during copying operation and moved away from the photosensitive drum to allow the drum to be detached from the support mechanism. The upper housing section is swung open to allow the photosensitive drum to be taken from it.
