PURPOSE:To enable a synthesized copy of plural originals to be obtained on the same sheet by returning the sheet having been copied by leaving only the assigned part of the original with a predetermined erasing region again to the copying position with a change-over means. CONSTITUTION:An erasing means 9 buried with metallic electrodes 28 to an insulating material 27 is provided. A screen 31 drawn with lines in the X, Y directions is provided above a monitor display part consisting of mirrors 17, 19, and a lens 18, in a manner as to oppose to a copying sheet 22. If with this constitution the part to be copied of the 1st original is put in the predetermined position of the screen 31 and copying is made by inputting this position by the instruction in the X, Y directions with an operating switch 32, the erasing means 9 operates to apply the voltage of reverse polarity to the electrodes 28 of the part to be erased, so that only the predetermined part is copied. If this copy is returned to the copying position with a change-over means 24 and the required part of the 2nd original is copied by the operation similar to that mentioned above, a synthesized copy is obtained. |
