PURPOSE:To permit sure and easy identification of information which is displayed similarly by providing a blank section which is not lighted between the respective kinds of information in displaying at least two kinds of copying information alternately with the same display device. CONSTITUTION:When a detector group 6 detects a jam of paper during copying operation, the copying operation is stopped on the spot; at the same time, a jam signal is outputted from a microcomputer 22, and the jam is displayed E1 on a display device 23. When the jam is dissolved, the device 23 is put out, and at the same instant, a timer set at the time t1 starts operation, and the set number of copying sheet is displayed N for the time t1 on the device 23. Unless a copying start switch SW1 is turned on before the time t1 times up, a timer set at the time t3 starts operating and the device 23 is put out until the time t3 elapses. Thus the blank section where the device 23 is put out for the time t3 after the display N is formed. |
