<p>PURPOSE:To offer always the copy which the user desires, by providing a paper quality setting 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 a paper feeding rolls 3 and 4. Information from not only no-paper detecting means 8 and 9 in parts 1 and 2, paper size detecting means 10 and 11 in parts 1 and 2, and upper stage and lower stage setters 12 and 13 which select either of the upper-stage paper feeding part 1 and the lower-stage paper feeding part 2 but also a paper quality setter 14 are inputted to a controlling circuit 15. The controlling circuit 15 performs processings for these 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. The paper quality setter 14 consists of a paper thickness setting part, a paper type setting part where different paper types are set by the transmittance of the paper, and a paper color setting part.</p> |
