Abstract
A centralized control system capable of remote controlling terminal devices such as a copying machine or automatic vending machine by using communication lines. The system displays information identifying the terminal devices which have not transmitted the information to a central unit after predetermined time. Further, the system is provided with a back-up power source for backing up a memory storing the information to be transmitted and an IC for clocking the present time. The information stored in the memory is to be transmitted when the power is supplied again in the case where the transmission has not been carried out at the predetermined time because the power source for the terminal device was shut off. Moreover, the system judges, in the case where an image forming apparatus is adapted as a terminal device, whether the image forming apparatus has recovered from trouble condition to normal condition by judging whether a copy paper is actually discharged.
