PURPOSE:To reduce the size and cost of a titled device and make it usable simultaneously for printing of a computer or the like and copying of originals by operating an optical scanning exposure device and a recording electrode group arranged at a right angle to the feed direction of recording paper simultaneously. CONSTITUTION:An optical system consisting of a mirror 10, a light source 11, and a lens mirror 12 as well as a pin electrode group 13 disposed at a right angle to the feed direction of recording paper 2 and a driving circuit 14 are provided. For printing of computers or the like with this constitution, electrostatic recording paper is used, and at the time when it passes under the electrode group 13, positive charge is applied on the paper and latent images are formed thereon. At the time of copying, zinc oxide paper is used, and the latent images corresponding to the optical images of an original 1 are formed by the optical system. When the printing of the computer and copying are to be synthesized simultaneously, zinc oxide paper is used, and the latent images are developed 6 and fixed 7. Thereby, the printing of the computer or the like and copying are accomplished simultaneously. |
