To efficiently make a relay multi-address transmission result report by an instruction from the same destination by receiving telephone number information and informing execution results of the relay multi-address transmission in one call connection by integrating them, when plural times of relay multi-address transmission is requested within a fixed period.

A sub-address and communication specifications are registered in a registration circuit 30 corresponding to a memory box via a signal line 30a by a control circuit 20. When the communication specifications corresponding to a sub-address signal is a judged as being the relay multi-address transmission, ID information of a TSI signal and an NSS signal is stored corresponding to a communication number, and an image signal is received by a memory by the control circuit 20. The relay multi-address transmission corresponding to the communication number is executed by the control circuit 20. The call is originated to the destination, to which the relay a multi-address communication is specified, by using a call originating circuit 22 based on the received information of the TSI signal by the control circuit 20. If there are no plural multi-address transmission reports to the same destination, a single relay multi- address transmission result is transmitted.
