Each transmission mode is designated by the signal line 20c. The modulator / demodulator 8 receives a signal output on a signal line 20b, outputs modulated data on a signal line 8a, receives a received signal output on a signal line 6a, and outputs demodulated data on a signal line 8b. Output.

The ANSam transmitting circuit 10 is a circuit for transmitting an ANSam signal. When a signal of a signal level "1" is output to the signal line 20d, the ANSam transmitting circuit 10 transmits the ANSam signal to the signal line 10a and outputs the ANSam signal to the signal line 20d. When the signal of the signal level “0” is being output, no signal is output to the signal line 10a.

The addition circuit 12 inputs the information of the signal line 8a and the information of the signal line 10a, and adds the result of the addition to the signal line 12a.
a. The reading circuit 14 reads an image of a document and outputs the read image data to a signal line 14a. The recording circuit 16 is for sequentially recording information output to the signal line 20e line by line. Further, the signal line 20g controls whether recording on the front side or recording on the back side.

The memory circuit 18 is used for storing raw information of read data or encoded information, and also for storing received information or decoded information.

The operation unit 22 has a one-touch dial, a speed dial, a numeric keypad, a * / # key, a start key, a set key, a stop key, a double-sided reading designation key, a registration key for the circuit 24, and other function keys. The pressed key information is output to the signal line 22a.

The double-sided printing function registration circuit 24 registers whether or not to execute double-sided printing via a signal line 24a.

The control circuit 20 controls the entire facsimile apparatus having a double-sided recording function according to the present embodiment.
In particular, the receiver notifies the transmitter of the presence or absence of the double-sided recording function, and before transmitting each page, the transmitter notifies the receiver whether this document information is the front side or the back side. Processing for changing the control at the time of reception is controlled depending on whether or not the receiver is notified whether the document information is the front side or the back side.

Specifically, when the transmitter notifies the receiver of the front side or the back side, when the front side and the back side are designated in order for each transmission page, at least two page units are set. The recording operation is started by the reception, and when the designation of the front surface is continued, the recording operation is started by the reception of the back surface information of at least one page or the end of the communication. Also, if the transmitter does not notify the receiver whether it is the front side or the back side,
The recording operation is started by receiving at least one page.
