Abstract

PURPOSE:To offer always the copy which the user desires, by providing a paper quality discriminating means in the paper feeding part of a copying machine and comparing not only the paper size but also paper quality information and generating a selecting signal only for coincidence. CONSTITUTION:Papers are supplied to the copying machine from an upper-stage paper feeding part 1 and a lower-stage paper feeding part 2 by paper feeding rolls 3 and 4. Paper quality detectors 12 and 13 are provided for papers fed from the upper-stage paper feeding part 1 and the lower-stage paper feeding part 2. Paper quality detectors 12 and 13 consists of transmittance detectors, color detectors, and thickness detectors respectively. Information from not only paper absence detecting means 8 and 9 and paper size detecting means 10 and 11 of the upper-stage paper feeding part 1 and the lower-stage paper feeding part 2 but also paper quality detectors 12 and 13 are inputted to a controlling circuit 15 through a discriminating circuit 14. The controlling circuit 15 performs operation processings of these input information to output a cut signal 16, an upper stage paper feed signal 17, a lower stage paper feed signal 18, or the like as a control output signal.
