Title: Image forming part structure of copying machine
Inventor: TAKAHASHI YOSHIAKI
IPC: G03G15/08
Filed: 1983-12-20
Abstract: PURPOSE:To facilitate maintenance operation, eliminate the possibility of photosensitive body damage, and attain formation at low cost by supporting a photosensitive body and its peripheral parts on a common frame which can be drawn out to a copying machine frame. CONSTITUTION:When the photosensitive body and its peripheral parts are cleaned, replaced, or adjusted, the common frame 3 is drawn out of the copying machine laterally. Then, when a subframe 4 is rotated as shown by an arrow C, the subframe 4 and a developing device 5 leave the photosensitive body 7 remarkably. Therefore, the developing device 5 or electrostatic charger 11, exposing lamp 12, platen glass 13, etc., supported on the subframe 4 are handled easily in cleaning, etc., without damaging the photosensitive body 7. Further, the photosensitive body and peripheral parts are supported together on the common frame, so the cost of formation is reduced.
