ABSTRACT:
An object of the invention is to reliably back up data stored in a memory provided in a transmitting/receiving apparatus by using a volatile memory even when a power source is shut down for a long period of time. The transmitting/receiving apparatus includes an image information memory composed of a volatile memory for storing at least image information, a control display section, a printing section, a scanner and a transmitting/receiving control section connected via a data bus line with a communication control section for transmitting/receiving via a telephone line. A main power source circuit supplies power to required sections in accordance to instructions of the control section. Then, the switching control section supplies power from a backup power source when it detects that the power source is shut-down. Then, receiving an instruction from the switching control section due to the shut-down of the power source, the transmission/receiving control section carries out a process for transferring data stored in the image information memory to another transmitting/receiving apparatus registered in advance via the control display section to evacuate and back up the data at the transfer destination to avoid a situation in which the data cannot be backed up by the backup power source.
