Next, the connection of the external terminal device (encryption device) 11 is detected by the interface line 16 (S1).
2) If not connected, communication is performed in the normal confidential communication mode as it is (S18).

If it is connected, communication is started (S13), and it is determined whether or not the encryption device is connected to the facsimile machine of the other party (S14). If the encryption device is not connected to the facsimile machine of the other party, communication is performed in the normal confidential communication mode without sending the secret code of the encryption device (S15) (S1).
8).

If the encryption device is connected to the facsimile machine of the other party, it is judged whether the passwords of the encryption devices are the same (S16).
Communication is performed in the normal confidential communication mode (S18).

If the personal identification numbers are the same, the communication data is encrypted and confidential communication is performed (S17).

In this way, the secret code of the encryption device is input to the facsimile device during the confidential communication, the connection of the encryption device is judged, and the secret code is collated, so that the communication is performed in the encryption mode during the confidential communication. be able to.
