Abstract

PURPOSE:To copy two overlapped images clearly even in the case of a large number of copies by providing an image storage element that can write and read the image and three optical systems. CONSTITUTION:An original on a platen 2b is irradiated on an image storage element 1 that uses an electrooptical single crystal such as Bi12SiO20 etc. by a lens 10 and the picture is stored. This picture is read by a read light source 12, a red filter 14 and a polarizer 15 and irradiated on a photosensitive body by a lens 10 and mirrors 30 and 32 to make a latent image. A large number of copies is obtained by this way. To obtain an overlapped image, the image on the element 1 is irradiated on a photosensitive body 24 and an image of other original 27 is further irradiated by a mirror 30, a lens 31 and a mirror 32 to make an overlapped image. By this way, plural overlapped images are made satisfactorily.
