Abstract

PURPOSE:To minimize the time required for returning a platen and an optical system by providing an original placing area covering two originals and moving the platen to project an original in the second area continuously after the first area is scanned optically. CONSTITUTION:A platen 1' where the first original 1 is placed and a platen 2' where the second original 2 is placed are provided as the platen. When the first original is copied, an illumination lamp 3, the first mirror 4, and the second mirror 5 are moved to positions 3', 4', and 5' to form a latent image on a drum 9. At this time, since a flapper 17 is placed in the position indicated by a solid line in Fig., a copy paper is carried to the position of a resist roll 22. When the second original is copied, the lamp 3 and etc. are still in the position 3', and the platen is moved to the position of the platen 1', and the second original is scanned. Thus, the time required for returning the platen and the optical system is minimized because the first original and the second original are copied alternately.
