ABSTRACT:
A control apparatus according to the present invention is a control apparatus collecting data related to copying machines and communicating with a centralized control unit on the basis of the data collected, including a communication device for calling the centralized control unit, a determination device for determining that connection with the centralized control device can not be made in spite of the fact that the communication device is activated, a setting device for setting a retransmission time on the basis of a random number in a predetermined time period in response to a determination output of the determination device, a timer device for counting the present time, and a control device for having the communication device call the centralized control unit again when the present time becomes the retransmission time.
