PURPOSE: To transfer incoming information which is individually memory- received to the other terminal by memory-transmitting reception data addressed to respective individuals, which a file memory-receives, from the file concerned to the terminal of a previously registered transfer destination ID when sub address members coincide.

CONSTITUTION: Sub address information transmitted from an optional ISDN facsimile is informed to an incoming-side facsimile through ISDN. A main control part 1 reads a file number from a file number memory 52, refers the read file number with sub address information and receives and accumulates the reception information into the file concerned in a picture data memory 51 controlled by said file number. When memory reception is terminated, a call is given to the transfer destination ID 53 which is registered in accordance with the file number and reception information accumulated in the individual file concerned is transmitted to the transfer destination ID concerned. Then, transmission completes and a processing terminates.
