ABSTRACT:
A device installed in a copier for selecting a magnification allows an operator to select a desired magnification by performing only a small number of manipulations which are predetermined on the basis of the format of paper sheets. This frees the operator from troublesome button selection and allows him or her to rapidly select a magnification with respect to different definite formats.
