4 and 5 show a sequence of communication procedures according to another embodiment of the present invention.

First, the communication procedure when Q = EOP, that is, when the transmission of one page is completed and there is no next original to be sent next will be described with reference to FIG.

When communication is started, first, from the receiving side to the transmitting side, a signal NSF indicating the number of remaining pages corresponding to the distance from the warning mark on the recording paper to the black band portion 2 and the receiving side identification. A signal CSI indicating information and a signal DIS indicating own terminal attributes such as resolution and paper size are issued. In response to this, the signal NS that responds to the signal NSF is sent from the transmission side.
S, a signal TSI indicating the identification information of the transmission side, and a signal DCS for instructing the transmission side to set the desired mode by referring to the signal DIS. Therefore, at this time, the transmitting side can know in advance the number of remaining printable pages on the receiving side.
Further, the transmitting side, following the signal DCS, transmits the signal Trai of the high speed modem for transmitting the facsimile message.
Issue a signal NCF and a signal TCF to check it.
On the other hand, on the receiving side, when the training of the high-speed modem is successful and the operation is established, a signal CFR indicating that the message transmission may be started is issued. Then, the transmitting side confirms the signal CFR, transmits the signal Training again, and then starts the transmission of the facsimile message Message of each document by the high-speed modem, and thereafter issues the signal RTC indicating the completion of the transmission to issue the facsimile message Mes.
The transmission of the page is ended. Then, the transmitting side issues a signal EOP (Q = EOP) because there is no next original to be transmitted. On the receiving side, the facsimile message Messa
If ge is correctly received, a signal MCF indicating that the ge has been correctly received is issued, and accordingly, a signal DCN indicating a disconnection command for transmission from the transmitting side is issued and the transmission is ended. That is, if there is no next original to be sent,
Even if the receiving side detects the warning mark 3 and informs the transmitting side of the number of remaining pages that can be printed, the transmission ends in response to the signal EOP from the transmitting side.

Next, based on FIG. 5, Q = MPSorEOM
A communication procedure when there is a next original to be transmitted next at the time, that is, when transmission of one page is completed will be described.

At the start of communication, when the signals NSF, CSI, DIS are issued from the receiving side as in the operation of FIG. 4, the signals NSS, TSI, DCS are accordingly issued from the transmitting side. Following this, the signal Trainin
g, emit signal TCF. Then the signal CF from the receiving side
Since R is issued, the signal Tr is transmitted from the transmission side in response to this.
aing, facsimile message Message
Is started, the signal RTC is issued, and the transmission of the message is ended.

However, at this time, when there is a next original to be sent to the sending side, that is, when Q = MPSorEOM and the warning mark is not detected on the receiving side, in response to the signal MPS or the signal EOM issued by the sending side. The receiving side issues a signal RTP indicating that the facsimile message Message has been correctly received but synchronization between transmission and reception must be established, and the process returns to the beginning (* 1) X of phase B. Then, the transmission of the facsimile message is continued according to the above-described communication procedure until there are no more originals to be transmitted on the transmitting side, that is, until the signal EOP is issued (Q = EOP).

However, when there is a next original to be transmitted to the transmitting side (Q = MPSorEOM) and the warning mark is detected on the receiving side, the receiving side starts the phase B (* 2).
Move from Y to the beginning (* 3) Z of phase B. The receiving side then issues the signal RTP and then continues to the signals NSF, CS.
I and DIS are issued to notify the transmitting side that the receiving side has detected the warning mark. Therefore, when the transmitting side receives this notification of the detection of the warning mark, it can know the remaining state of the recording paper on the receiving side by looking at the number of remaining pages sent from the receiving side. Then, a signal DCN indicating a transmission disconnection command is issued to end the transmission.

[0034]

As described above, according to the facsimile apparatus of the present invention, the user on the receiving side can know the time when the roll paper is exchanged in advance, so that the inconvenience that the recording is interrupted midway is eliminated, and the transmitting side is also eliminated. Since the user knows the number of remaining printable pages on the receiving side during communication, it is possible to take appropriate measures such as exchanging recording paper. Particularly, during the communication of a plurality of pages, the transmission is interrupted, the inconvenience of having to retransmit the data can be eliminated, and the communication can be performed efficiently.
