PURPOSE:To obtain the copy of high confidentiality in the form of original images by changing significant image patterns to insgnificant image patterns and performing recording in a copying machine or the like. CONSTITUTION:The respective elements on the keyboard of the copying machine or the like are connected to an electronic control unit 30. Image information processing circuits 60 and 70 are connected to the input-output part 34 of the ROM34 in the unit 30. In the circuit 60, the copying of obtaining copies by changing the image information of the original images read with a CCD element 16 into illegible picture element information distributions and exposing the photoreceptor of the drum by an optical fiber tube OFT is accomplished. In the circuit 70, the copying of obtaining copies by changing the picture element information of the original images having been read with the element 16 into the picture element distribution of the original images of the copy placed currently on the original platen and exposing the photoreceptor with the OFT is accomplished. |
