PURPOSE:To quickly report cut-off of power supply to the management center side in the case of cut-off of power supply by switching a feeding circuit to the auxiliary power source to send power switching data to the center side at the time of cutting off a main power supply circuit. CONSTITUTION:When a main power supply side A is cut off and the feeding circuit is switched to an auxiliary power supply side B, data related to power switching is set as management data for transmission. The center side is called by a transmission management means 11. When a centralized management device 91 on the center side is connected thereafter, power switching data set as management data of the transmission side is transmitted. Thus, the center side is informed of the occurrence of some abnormality in the main power source of a pertinent copying machine management device, and a proper countermeasure is taken. |
