ABSTRACT:
A copying machine includes a drive motor for driving the copying machine, a device for generating a start signal for starting the drive motor, an auto-shut device for stopping the drive motor a predetermined period of time after the completion of a copying operation, and a mechanism for carrying out a multi-copying operation in which a plurality of copying operations are carried out sequentially. The copying machine further includes a device for producing a first signal in response to each copying operation, a device for cancelling the auto-shut device and for starting, without any stop of the drive motor, a next copying operation, in a case when the start signal is generated before completing the count of the predetermined period of time for the auto-shut mechanism, or when the multi-copying operation is carried out, a device for discriminating whether the drive motor is in an on-state or a off-state, a device for producing a second signal in response to the generation of the start signal during when the discriminating device discriminates that the drive motor is in off-state, a counter device for counting the first and second signals, and a display device for displaying a number counted by the counter device.
