PURPOSE:To read a desired variable power ratio speedily with one variable power ratio readout key and to simplify a constitution by reading sequentially variable power ratio values which are set in past copying operation from the variable power ratio having the highest frequency of use. CONSTITUTION:When the variable power ratio readout key 57 is not operated, the variable power ratio set on a set variable power ratio ten-key 53 or the variable power ratio set with a unimagnification return key 60 is selected and a copying operation is started with a print key 51. When the key 57 is operated, on the other hand, the largest variable power ratio among variable power ratio values stored in memories M1-M10 of a microcomputer 6 is obtained and when there are >=2 variable power ratio values, they are selected from the variable power ratio close to the memory M1. Then, the largest variable power ratio is displayed 58 and copying operation is started with the key 51 on the basis of the displayed variable power ratio; and stored variable power ratios in the memories M1-M9 are shifted to the memories M2-M10 and the variable power ratio in the copying operation is stored in the memory M1. |
