8 is a network control unit (NCU). The facsimile machine of this example! At the time of transmission, the image information 20 is binarized by the read information processing section 25 and is temporarily stored in the image information storage area of the RAM 23. The image information stored in the image information storage area of the RAM 23 is read out, compressed by the data compression section of the data compression/data restoration section 26, modulated by the modem 27, and then sent to the network control section (N
CU) 28. The compressed image information transmitted via the telephone line is input to the modem 27 via the network control section 28, demodulated by the modem 27, and then restored by the data restoration section of the data compression/data restoration section 26. The restored image information is stored in the image information storage area of the RAM 23. Further, image information is read from the image information storage area as needed and supplied to the printer 29, and a document based on the read image information is recorded on recording paper by the printer 29.

The operation of one embodiment of the present invention constructed as described above will be explained with reference to FIGS. 2 to 5.

As shown in FIG. 2, in this embodiment, the facsimile device 20 receives a confidential communication from the facsimile device 10, and the facsimile device 20 receives the confidential communication from the facsimile device 30. The following describes the operation during confidential reception.When a call is received from the sending facsimile 10, it is determined whether the communication is confidential or not, whether or not there is a confidential flag set in the non-standard function setting signal (NSS). If the communication is confidential, it is determined whether the / password sent from the sending facsimile 10 is the same as the one registered in the password storage area of the facsimile machine 10.

If they are the same, confidential reception is performed, a confidential flag is stored in the confidential flag area, and the received pixel information is stored in the second RAM 231. Thereafter, the polling destination side is set using the polling instruction key 223, and when the polling flag is stored in the polling flag area, the confidential reception document can be transmitted by polling. Polling called party settings can also be performed before confidential reception. The effect at this time is to enable the confidential reception document received after the polling called side setting is set as the polling called document.

Next, the operation during polling communication will be described using FIGS. 4 and 5. FIG. 4 shows a facsimile device 30 on the calling side.
