Abstract

PURPOSE: To superpose two kinds of positive and positive originals and perform copying of composite images through one exposure by performing light image irradiation by excluding the respective specified regions of the 1st and the 2nd originals, then applying copying treatment and superposing the 1st on the 2nd.
CONSTITUTION: The region to be written of an original 31 (within the broken line) is assigned by an assigning device 33 and an optical system is scanned, at the same instant of which a timing controller 34 is so operated that only the portion within the region by the assigning device 33 is stored in a memory device 29. Next, the rgion of the originaly 32 to be written is painted densely with a black ink and the light image of the original 32 is projected onto a photosensitive drum by the scanning optical system. At this same instant, the image signal of the original 31 is written from the memory device into the drum by a light image writing device 30 through the operation of a controller 34. In this way, the composite images comprising superposing the light images of the specified region of another original on the specified region of the light image of one original are duplicated.
