PURPOSE:To copy a specified standard size from an original in optional size by providing a means that calculates magnification necessary for obtaining standard paper size and a means that sets the magnification basing on the result of calculation. CONSTITUTION:A magnification scale 17 on which graduations that satisfy relation between magnification to obtain objective standard size paper and length of the original are scored is provided on the side of an original placing face 1 conforming 1.0 of the scale to a marker 18. In this case, when the corner of the original is fitted to the corner 19 of the face 1, the scale indicated by the corner 21 of opposite side becomes magnification necessary for obtaining the standard size. Accordingly, by setting read magnification scale and executing copying, a copy of required standard size can be obtained. |
