ABSTRACT:
A copying machine control system in accordance with the present invention includes a control terminal collecting data about a copying machine and a centralized control unit collecting data from the control terminal. The centralized control unit includes a first timer device for counting the present time, and a transmitting device for transmitting the present time counted by the first timer device as the present time data. The control terminal includes a first receiving device for receiving the data from the copying machine, a second timer device for counting the present time, a communication device for communicating with the centralized control unit on the basis of the data received by the first receiving device when the present time counted by the second timer device comes to a predetermined time, a second receiving device for receiving the present time data from the transmitting device of the centralized control unit, and a correcting device for correcting the present time counted by the second timer device on the basis of the present time data received by the second receiving device.
