Abstract: PROBLEM TO BE SOLVED: To provide an automatic cleaner for the raster scanner projection window of an electrophotographic marking machine. SOLUTION: This automatic projection window is provided with a wiper 116 brought into contact with the projection window. The wiper 116 is fitted to a wiper actuation mechanism. Then, the wiper actuation mechanism is constituted so that all over the projection window is wiped by the wiper when a paper tray 128 is drawn out, for example and provided with a cable 118 arranged between two pulleys 120 and 122 by giving a gap. One pulley out of the pulleys 120 and 122 is provided with a gear 126. Then, the gear 126 is meshed with the rack gear 132 of the tray 128.
