Abstract

PURPOSE:To obtain a copy in which the unnecessary parts of an original are erased by utilizing a shielding sheet and shifting the sheet to an unnecessary copying part when copying a part of the original and controlling an erasing device corresponding to the quantity of moving and thereby erasing the latent image by an erasing device. CONSTITUTION:When a latent image part 30a passes, up to at least segments L1-Li are lit up, and when the latent image part passes successively segments Li-Li-3 are put out and segments Li-2-Li are lit up as before. Thus, by using shading sheets 3a, 3b to copy erasing excessive parts instead of copying the full face of an original 2, a partial copying can be made by eliminating the handling of inserting a sheet of white paper etc. Even in the case where shading sheets 3a, 3b are used to detect the size of the original and to select a copying paper, the selecting operation is not obstructed by this.
