Abstract
1331870 Electro-photographic copier FUJI PHOTO FILM CO Ltd 30 Dec 1971 [30 Dec 1970] 60824/71 Heading G2H Photo-conductive sheets cut from a roll 11 and transported by endless belts 15, 16 (and 15', 16') Fig. 3 (not shown) are charged at 23, exposed at 10 to a first colour separation image by an optical system 26-30, developed at 33 with a first coloured toner, charged at 40, exposed at 41 to a second colour separation image by refocusing the system 26-30, developed at 36 with a second toner, charged at 42, exposed at 43 to a third separation image by refocusing system 26-30, and developed at 37 with a third toner to produce a multi-colour copy. Preferably the sheets are pretreated at any stage before development, with insulating liquid 19; are charged by corona discharge wires or needles associated with earthed backing rollers; are line-by-line or whole frame exposed using a lamp 27, lens 28, diffuser 29, original 26, lens 31 and filter 30 mounted on a movable base 32 (alternatively exposure may be made via a reflector or by using a zoom lens); are developed using liquid suspended toner and mesh development electrodes 38, 38', 38"; are washed and squeezed after each development; and are finally dried at 44 and deposited in a tray 47. To position the sheets, accurately for exposure, photo-electric elements (62, 63) may be positioned before and after the exposure stations to stop the endless conveyor belts.
