Abstract

PURPOSE:To decrease standby time and improve an efficiency of the copying operation by providing an optical system which transmits the image of an original to the exposure part of a photoreceptor and an optical system which transmits the image of the copy discharged from a fixing device to the exposure part of the photoreceptor. CONSTITUTION:An optical system which transmits the image of an original 12 such as book placed on an original imposing plate 7 to the exposure part 13 of a photoreceptor 1 by means of a light source 8, a shutter 9 and mirrors 10, 11 is formed. Also, another optical system which transmits the image of the copy which is being discharged from a fixing device 5 to the exposure part 13 of the photoreceptor by means of a light source 14, mirrors 15, 16, a shutter 17 and said mirrors 10, 11 is formed. Hence, the operator is able to remove the original 12 from the plate 7 upon ending of copying by the optical system consisting of the light source 8, a lens device 9 and the mirrors 10, 11 and to beforehand set the next different original thereon by making use of the time while the copying by the image of the copy is being accomplished.
