PURPOSE:To enable changing copying operation release by means of a degree corresponding to evaluation by providing a means inhibiting a copying operation by means of the degree corresponding to evaluation and a copying operation release changing means. CONSTITUTION:A control 800 drives a scanner 200, reads an original image and extends it in an image memory. In parallel with this, an evaluating means 400 compares a density signal which is digitized while shading-correction is performed with a pattern signal which is transmitted from a copying inhibition object pattern storage part 420 so as to transmit an evaluation signal which expresses a max. 100 level of the degree of ambiquity to the controller 800. The controller 800 judges whether or not electrostatic photograph process is executed while an original is being placed on a platen in accordance with the value of the evaluation signal and also decides the carrying destination of the original. An original control circuit 110 makes the start of a program for executing a electrostatic photograph process impossible when the evaluation signal indicates more than 90%, for example. |
