数の機能機器より構成される。As is well known, an electrophotographic copying machine includes an exposure optical device that performs optical scanning of a document, a photoreceptor drum, various process equipment that performs image processing on the circumferential surface of the photoreceptor drum, a paper feeder and paper feeder, and a fixing unit. It is composed of a large number of functional equipment.

時にはいちいち止めビスを外して作業を行なわなければ
ならず、作業がやっかいで復旧に手間どる場合が多い。By the way, in conventional electrophotographic copying machines, these functional devices are either directly screwed to the machine frame, or have a structure in which each functional device can be removed along a rail, etc. built or laid on the machine frame. It is said that Therefore, in the former structure, when a functional device breaks down or maintenance is required, it is necessary to remove the fixing screw each time, which is a tedious task and often takes time to recover.

。In particular, each process focuses on photosensitive drums, including image formation, transfer,
Due to cleaning and other operations, it is necessary to arrange and fix the parts with accurate dimensions, and the assembly process takes a considerable amount of time. Although the latter structure improves the speed of work, in cases where the faulty device is not obvious or when maintenance work is being performed on multiple devices at once, it is necessary to take out a large number of devices individually. It is necessary to inspect or clean the
In terms of flexibility, there is still plenty of room for improvement.
