ABSTRACT:
A copying machine in which copying magnification can be changed comprises a slide lever for selecting an arbitrary copying magnification and a CPU for calculating the copying magnification based on the amount of travel of the slide lever, wherein the CPU controls the copying machine such that the copying operation is carried out at desired prescribed magnification rates regardless of the set position of the slide lever in the equal scale magnification region and in prescribed magnification copying regions which are frequently used and that the copying operation is carried out at a magnification rate corresponding to the set position of the slide lever in particular magnification set regions other than the above described regions.
