Is transmitted (process 250), and a response signal from the receiving side is received (process 251). It is checked whether or not the response signal received at that time is the message confirmation signal MCF (decision 252). If the result of the decision 252 is YES, the counter i is transmitted to transmit the image information of the next page.
Is incremented by one (process 253), and the routine goes to judgment 242. When the result of the determination 252 is NO,
In order to transmit the same page, the process proceeds to the judgment 242 without updating the value of the counter i.

When the transmission of the image information of all transmission pages has been completed and the result of determination 249 is YES, a procedure end signal EOP is transmitted (process 254), and a response signal from the receiving side is received. (Step 255). It is checked whether or not the response signal received at that time is the message confirmation signal MCF (decision 256). If the result of the decision 256 is YES, a disconnection command signal DCN is sent out (process 257) and the predetermined information A channel termination procedure is executed (step 258), and a call disconnection / release procedure is executed (step 2).
59), the selected state of the CODEC 15 is terminated (processing 26).
0), the process proceeds to step 228, the document management information is updated for the destination at that time, and the subsequent processes are executed. When the result of the determination 256 is NO, the determination 24
2 and resend the image of the last page.

As described above, in the present embodiment, when the transmission operation in the relay transfer mode is performed, in any combination of the terminal mode of the relay requesting station and the terminal mode of the receiving station, the receiving station identifies the relay requesting station. Since the situation where information is added is created, the user of the receiving station can clearly know the source of the received original at that time. However, when the relay requesting station prohibits the addition of a call identification line, the identification information of the relay requesting station is not added to the received document, so that the image intended by the user of the relay requesting station can be obtained at the receiving station. it can.

In the above-described embodiment, the relay requesting station specifies the receiving station by using the shortened dial information of the relay station. However, the relay requesting station transmits all necessary information. It is also possible to specify a receiving station.

[0092]

As described above, according to the present invention,
Since the receiving document having the content of the document with the identification information of the relay request station added thereto is received by the receiving station, the user of the receiving station can correctly recognize the sender of the received document. If the relay request station prohibits the addition of a call identification line, the received document reflecting the state is recorded and output at the receiving station. And the receiving station can obtain the effect appropriately.
