Abstract

PURPOSE:To effectively prevent the misuse of copied matter without impairing the freedom of design of the copying machine itself by providing an original detector, discriminator and controller. CONSTITUTION:An original detector 110-1 which detects the patterns of the original supplied for the purpose of copying is provided in proximity to an original platen 102 and is subsequently connected with a discriminator 201-1 which compares and discriminates the patterns of the original and the predetermined patterns and an copying machine control unit 209-1. Then, when a print switch 210-1 is pushed, exposure, development and transfer are accomplished, and at the same time the original is read by the original detector 110-1. If it is the original having a problem, a signal is emitted from the discriminator 201-1 to the copying machine control unit 209-1 so that turning of a turnover plate 301 is obviated and the copying paper discharged from a paper-discharge roller 302 is passed through ink-impregnated roller pair 304 by the turnover plate 301 and subjected to make image reading impossible, after which it is held on an inside tray 305.
