2. Description of the Related Art FIG. 2 shows CCITT Recommendation T. FIG. 3 is a diagram showing the basic protocol elements and sequence of the binary code signaling method among the transmission control procedures for telephone network facsimile based on 30. FIG. 3 is a diagram showing the HDLD frame structure adopted in this binary code signaling method. .

[0003] In this binary code signaling system, when the receiving side receives a calling signal CNG (calling tone) from the calling terminal, the receiving side receives the call signal CNG (calling tone) from the calling terminal 1.8 to 2.5 seconds after the called terminal is connected to the line. It sends out a CED signal (called terminal identification signal), and then notifies its own terminal attributes such as resolution and paper size using a DIS signal. The sending side uses this DIS
Refer to the signal and set the terminal constant used for subsequent communication to DC
Specified by S signal. Further, the transmitting side sends a high-speed modem training signal for transmitting a facsimile message and a TCF signal for checking the training signal, following this DCS signal. On the receiving side, if the high-speed modem is successfully trained and operational, it responds with a CFR signal. As a result, the sender starts sending a facsimile message using the high-speed modem. When the transmission of one page of facsimile message is completed, the sending side sends an MPS signal indicating the end of the page (see (a) in Figure 2), and the receiving side responds to this with an MCF signal (message confirmation signal) (see Figure 2 (a)). (See 2(b)). On the transmitting side, the next page of messages is further transmitted, and when that page is completed and there are no other messages to be transmitted, an EOP signal (procedure end signal) is used to notify the end of transmission. When the receiving side receives the EOP signal, it responds with the MCF signal and sends the DCN signal (disconnection command signal).
The process moves to the call disconnection procedure.

[Problems to be Solved by the Invention] In a facsimile transmission/reception system using the conventional transmission control procedure as described above, when transmitting a message that spans multiple pages, a (a) and (
It is necessary to perform a handshake by exchanging the MPS signal and MCF signal shown in b), so if the message spans many pages, the time required for this handshake will increase the overall transmission time. Become. In particular, control signals configured in frames such as MPS and MCF are all 300b in principle.
Since data is transmitted and received at a low transmission speed of ps, if the handshake is repeated many times, the resulting increase in transmission time cannot be ignored.

[0005] The present invention was made in view of the problems of the prior art as described above, and when transmitting a multi-page message, it eliminates the need for handshaking between the transmitting and receiving terminals after each page ends, thereby reducing the transmission time. It is an object of the present invention to provide a facsimile transmission/reception system that can shorten the overall time.

[0006]

[Means for Solving the Problems] As shown in FIG. 1, a facsimile transmission/reception system according to the present invention includes a reading means 111 for reading a message in a transmission document, and an entire page of the message read by the reading means 111. a detection means 113 for detecting the number of pages and the number of lines for each page (total number of scanning lines); and a detection means 113 for transmitting a signal indicating the message and data indicating the number of pages and lines detected before, during, or after this transmission. a transmitting means 112 for transmitting a message; a receiving means 114 for receiving the message signal and data indicating the number of pages and lines from the transmitting means 112 via a line 118; and a receiving means 114 for storing the message received by the receiving means 114. an editing means 116 for editing the contents of the message stored by the storage means 115 based on the data indicating the number of pages and lines; It is characterized by including an output means 117 for outputting a hard copy of the page message.

[0007]

[Operation] According to the present invention, on the transmitting side, the detection means 1
13 detects the number of pages and lines of the entire message to be transmitted, and the transmitting means 112 transmits data indicating the number of pages and lines before, during, or after transmitting the message signal. On the receiving side, upon receiving the message signal, the receiving means 114 temporarily stores it in the storage means 115.
Store in. Further, upon receiving data indicating the number of pages and the number of lines, the receiving means 114 outputs this to the editing means 116. The editing means 116 edits the contents of the message from the storage means 115 for each page based on the number of pages and the number of lines from the receiving means 114, and sends the edited message to the output means 117.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 4 is a block diagram showing a schematic configuration of a transmitting device in an embodiment of the present invention, and FIG. 5 is a block diagram showing a schematic configuration of a receiving device in this embodiment.

In FIG. 4, reference numeral 1 denotes a reading section that reads a message on a transmission document. This reading section 1
The message signal indicating the read message is subjected to redundancy reduction encoding processing by the encoding unit 2 using an information compression method such as the MR (Modified Read) method or the MH (Modified Huffman) method. CPU3 is
During the encoding process by the encoder 2, the output from the encoder 2 is received and the number of pages of the message and the number of lines for each page are counted.

When the encoding process is completed, the CPU 3 controls the modem unit 4 and the NCU 5 to transmit this message signal to the other party via the telephone line 6. Note that transmission in this case is performed according to the signal sequence shown in FIG. Handshake by exchanging signals and MCF signals ((a) and ((a) in Figure 2)
I try not to do things like b)). Moreover, after the transmission of this message signal is completed, the CPU 3
EOP included in the digital identification frame (see Figure 3)
Before sending out the signal (procedure end signal), data indicating the counted number of pages and lines is added to the non-standard function frame (see FIG. 3) and sent to the other party.

The CPU 15 on the receiving side temporarily stores the message signal from the sending side in the memory 13 via the NCU 11 and the modem section 12, as shown in FIG. The message signal stored in this memory 13 is then decoded by a decoding section 14, and a recording section (printer) 16
sent to. Further, the CPU 15 receives data indicating the number of pages and lines in the non-standard function frame from the transmitting side, and controls the recording unit 16 based on the number of pages and lines. That is, CPU1
5 is the content of the message sent from the decoding unit 14,
The recording unit 16 is controlled so that the message is divided into pages and recorded (printed out) according to the number of lines on each page.

As described above, according to this embodiment, the CPU 3 on the sending side counts the number of pages and lines of the message to be sent, and puts data indicating this in the non-standard function frame of the HDLC frame and sends it. Receiving side CPU
15 controls the recording unit 16 based on the data on the number of pages and number of lines in this non-standard function frame, and records the contents of the message by dividing it into each page, so it cannot be sent as before. This eliminates the need for a handshake between the sender and receiver each time a page of messages is completed, thereby reducing transmission time.

In this embodiment, the data on the number of pages and the number of lines is transmitted after the message signal has been transmitted, but the present invention is not limited to this. For example, the message signal is The data on the number of pages and the number of lines may be temporarily stored in a memory (memory used for memory transmission) before transmission, and transmitted before or during the transmission of this message signal.

[0015]

As described above, according to the present invention, the sending side detects the number of pages and lines of the entire message to be sent and transmits it, and the receiving side sends the message based on the number of pages and lines. I'm trying to edit it, so
When transmitting a multi-page message, it is no longer necessary to perform a handshake between the transmitting and receiving terminals every time each page ends, and the overall facsimile transmission time can be shortened.
