PURPOSE:To select a kind of a roll paper and its cut length, and to supply automatically a form of a correct size by constituting so that an original size is detected, and plural roll papers, a feeding means and a cutting means are driven in accordance with the original size by a control means. CONSTITUTION:A necessary form size is determined by inputting to a controller 8 signals (a), (b) obtained by detecting the tip of the rear end of an original 3 passing through on a guide plate 5, a magnification setting signal (c) inputted in advance, and a signal from roll paper width detectors 10a, 11a. When its size is determined as A3, a roll paper 10 for A3 is fed by a feed roller 12, and cut to a length of A3 by a cutter 14. A roll paper 11 is a form of a different size. Accordingly, since a correct form is fed automatically, a troublesome operation becomes unnecessary, an economical loss of time caused by a selection error of a roll paper can be eliminated. |
