ABSTRACT:
A copying machine which can stop or interrupt a copying operation of reserved originals even when it is still in the middle of a copying operation so as to permit the copying of un-reserved originals. The interruption takes place when a human body sensor detects a person coming up to the copying machine, or when a timer counts up a predetermined time. Also, the copying machine has a first counter which counts a first predetermined time after the end of the copying operation. If no copying operation is performed during the first predetermined time, a second counter starts to count a second predetermined time immediately after the first predetermined time. During the counting of the second predetermined time, a copy start button is made invalid. When the second predetermined time is counted, the reserved copying operation starts.
