PURPOSE:To easily create one composite document from plural originals by developing a latent image formed when reflected light from either of the 1st and the 2nd originals is reflected light from a black area without developing as a background a latent image formed when reflected light from the 1st and the 2nd originals if reflected light from a white area as well as those originals. CONSTITUTION:When an oblique projection part in an original on an original display part 1 is copied, the image at the uncopied part is shielded with a mask 7., and the image of the unshielded part, i.e. part on the original display part 1A corresponding to the hatched part on the original display part 1 to be copied is shielded with a mask 7A. Consequently, only either image is exposed to a photosensitive drum 6, so one copy image 8 is obtained as if the original were cut and stuck. At this time, when the mask 7 and 7A are linked with each other through a connecting rod 7B, double exposure due to overmasking or deficient masking between the two masks 7 and 7A is prevented effectively. |
