Abstract

PURPOSE:To obtain a positive picture without using a special device in a printing method that a computer output and a copy are combined through light by a method wherein in both of them, a photosensitive plate is exposed to a positive light image. CONSTITUTION:To a photosenstive drum 1 for transfer-copying a photograph rotating in the direction of the arrow, the serface of the drum is charged positively by a charger 6. The output of the computer is exposed to a positive picture through an optical fiber tube 7, zero or negative charges are given to the exposed part, then a light source 10 is turned ON-OFF under the control of a control circuit 13, reflecting light from a copy 12 mounted on a stand 11 is irradiated on the photosensitive drum 1 through a lens 9, a slit cover 8 and zero or negative charges are given to the exposed part. Then, an electrostatic latent image made by the positive potential on the drum 1 is developed by a developing device 2 and the attached developer is tranoferred to a sheet 3 by a transfer device 4 to make a positive copy.
