BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of collecting a plurality of short originals and transmitting them as one page.

[Conventional technology]

FIG. 5 is a block diagram of a conventional facsimile machine,
In the figure, reference numeral 1 is a reading unit that illuminates an original to convert an image of one line into read image information, and 2 is connected to an encoder 3, and according to the instruction, the original is advanced by one line at a predetermined resolution. The document traveling unit notifies the size of the document determined from the length in the scanning direction and detects the start and end of the document.

The encoder 3 is connected to the reading unit 1 and recommended by CCITT Recommendation T.4.
According to the above, the image information for one line is encoded. CCITT Recommendation 4 is connected to encoder 3 to modulate coded data and demodulate received signals
A T.4, T.30 compliant modem, 5 is a line-corresponding unit which is connected to the modem 4 and has an interface circuit for conforming to the telephone line standard.

6 is connected to the modem 4 and the received data is recommended by CCITT
A decoder for decoding image information according to T.4, a recording unit 7 connected to the decoder 6 and printing the decoded image information on a thermal recording paper, etc. 8 an original running unit 2, an encoder 3, a modem 4, a line corresponding unit 5, which is a main control unit connected to the decoder 6 and the recording unit 7 for controlling each and performing communication in accordance with the procedure of CCITT Recommendation T.30.

Next, the operation will be described. In the case of transmission, as an example of a document, as shown in FIG. 6 (a), a document that transmits two A5 size documents horizontally is used. Communication signals are shown in FIG.

The document traveling unit 2 detects the start and size of the document and notifies the main control unit 8. The main controller 8 controls the line interface 5 by inputting a telephone number or the like and dials. The receiver receiving the incoming call closes the connected line, receives the CI signal in step ST1 of FIG. 7, sends the CED signal (callee identification signal) in step ST2, and receives it in step ST3. It sends out a DIS signal (digital identification signal) indicating the reception capability of the machine.

The DIS signal is demodulated by the modem 4 via the line interface 5,
The main control unit 8 determines the communication mode to be transmitted, determines the communication mode to be transmitted, and uses the modem 4 to transmit the DCS signal (digital command signal) and the TCF signal (training check signal) in step ST5 to check the training. The signal is modulated and transmitted via the line interface 5.

When the receiver receives the DCS signal and the TCF signal in steps ST4 and ST5 and confirms that transmission of image information may be started, the receiver sends out a CFR signal (reception preparation confirmation signal) in step ST6.

The CFR signal is demodulated by the modem 4 via the line interface 5,
Transmission of the image information of the first page decoded by the main control unit 8 is started in step ST7.

One line of the original is converted into image information by the reading unit 7, sent to the encoder 3, and encoded. When one line of data is coded by the encoder 3, the document running unit 2
Then, the document traveling unit 2 advances the document by one line. After that, the reading unit 1 converts the next one line into image information.

The converted image information is sent to the encoder 3 and coded. The coded data is modulated by the modem 4 and sent to the line through the line corresponding unit 5, and the image information is recorded by the above procedure until the end of the first page document is detected by the document running unit 2. It is sent (step ST7).

In the transmitter, when the document traveling unit 2 notifies the main control unit 8 of the end of the document, the presence or absence of the next document, and the size thereof,
The main control unit 8 finishes sending the image information, and there is the next document,
When the transmission mode is the same as that of the previous document, the main control unit 8 sends the MPS signal (multi-page signal) through the modem 4 and the line interface unit 5 in step ST8. Receiver is step ST
When the MPS signal is received in 8 and the MPS signal is accepted, the MCF signal (message confirmation signal) is transmitted in step ST9.

In step ST9, the MCF signal is transmitted via the line interface 5 to the modem 4
At step ST10, the transmitter starts to send the image information of the second page after being demodulated by the main controller 8 and decoded. The same process as the first page document is performed on the second page document.

When the document control unit 8 notifies the main control unit 8 that the second page of the document has ended and that there is no next document, the main control unit 8
Ends the transmission of image information, and in step ST11, transmits an EOP signal (procedure end signal) via the modem 4 and the line interface 5.

The receiver receives the EOP signal in step ST11, and when accepting the EOP signal, sends the MCF signal in step ST12.

In this step ST12, the MCF signal is demodulated by the modem 4 via the line corresponding part 5 and decoded by the main control part 8, and the DCN signal (line disconnection command signal) indicating the line disconnection is sent because all the transmission originals have been completed. Then, the transmission is completed and the line is released.

Since it is configured to be stored in the memory, there is an effect that the boundary between pages is clear.

〔The invention's effect〕

As described above, according to the present invention, the document traveling unit is notified of the traveling command until the document traveling unit detects the end of the document, and the image information for one short document is stored in the page memory. When the document size of the short document to be transmitted next to the document size of the short document matches, the image information of the boundary line output by the boundary line generator is stored in the page memory, and the running command is sent to the document running unit. Image information for one short original to be notified and transmitted next is stored in the page memory, and a plurality of short originals are stored as one-page originals in the page memory. As a result of being able to collectively transmit minute short documents, the transmission time can be shortened and the boundaries between the respective short documents can be made clear.
