PURPOSE:To enhance image quality and to reduce size and weight, by fixing a master plate to a conductive rotary drum by evacuation to rotate it, stabilizing the synchronous motion velocity of an original and a master plate, and raising precision of an optical distance in an exposure section. CONSTITUTION:ZnO paper 1 is fed from paper feed tray 4 of paper feeder 3 through roller 5 and guide rollers 6, 7 by turning on a switch, and fixed to the circumference of conductive rotary drum 2 by actuating an evacuation device at the same as time the end of paper 1 is detected with sensor 8, and paper 1 is carried by rotating drum 2. Paper 1 is fed to charging mechanism 10 to uniformly charge paper 1, delivered to exposure mechanism 12, and the right image or the mirror image of original 13 placed on original imposing plate 14 moving in synchronism with paper 1 is projected on paper 1. |
