PURPOSE:To prevent erroneous setting by composing a display part of the 1st and 2nd display devices, and displaying a corrected quantity of copies on the 1st display device when a predetermined quantity is corrected during copying operation. CONSTITUTION:The display part 44 of a copying machine consists of display devices 45-49, and the 1st and 2nd display devices 50 and 51 which display numerals by having been segments driven. When a signal which shows a corrected quantity n' is inputted from a ten-key numeric pad 12 to a control circuit 38, a control circuit 18 compares the inputted corrected quantity n' with a preset quantity (n) for copying and copying operation is cartied out until the quantity of copies having been made becomes equal to the corrected quantity n'. Therefore, an operator need not input a subtracted value (n'-m) on the ten-key numeric pad 12 newly, and the erroneous setting of a corrected quantity is prevented. |
