PURPOSE:To simplify the setting of magnification in a zoom copying work and to improve working efficiency by forming a magnification storing means for storing plural copying magnification, a frequency counting means for counting the number of times of using each copying magnification stored in the storing means, and a copying magnification display means. CONSTITUTION:A display part 2 is formed in an operation part 1 and the copying magnification display device 4 is arranged on the approximately center part of the display part 2. The copying magnification set up by the operation of a key related to the copying magnification is displayed on the display device 4, a lens in an optical system is moved to a position for attaining the copying magnification and the rotational speed of a photosensitive body is controlled at a speed for attaining the displayed copying magnification simultaneously with the operation of a print switch 3 to execute the copying operation. A ROM 22 for storing a program regulating the lens position of the optical system and the CPU operation such as the rotational speed of the photosensitive body or the like, a RAM 23 for inputting/outputting various data relating to the copying operation and a driver array 24 connected to the operation part 1 are connected to a CPU 21. |
