Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a facsimile transmission device, and more particularly to a device capable of broadcasting communications to all of a plurality of facsimile terminals, including facsimile terminals of different types.

A facsimile broadcasting device is a device that transmits the same document to multiple facsimile terminals simultaneously or sequentially.

When storing documents to be sent in memory and sending them sequentially to multiple facsimile terminals, all 7
Axismi') has the disadvantage that it takes a long time to complete communication to the terminal.

However, in order to simultaneously transmit to multiple facsimile terminals, it is necessary to follow a predetermined communication procedure for each line. After connecting and setting the facsimile reception function and communication mode, it is necessary to transfer messages. For facsimile communication, internationally standardized communication procedures are defined, and normal facsimile terminals follow the communication procedures. For example, the communication procedure of a G3 machine that operates as a facsimile terminal using digitized compression codes is as shown in FIG. In other words, in phase A, when two calls are made and two incoming calls are connected and the communication button is turned on, the call-broken station identification signal CED is sent from the receiver side to the transmitter side. Then, in phase B, a DIS signal (digital identification signal) is sent from the receiver side, and details of the receiver functions are recognized at the transmitter side. An NSF signal is sent when a non-standard function is activated. Next, a DC8 signal specifying the receiver function is sent from the transmitter side, followed by TCP
A signal ()laning check signal) is sent. Due to this, the 11# status is checked and the CF is sent from the receiver side.
An R signal (reception rate, reliability, reliability) is sent back. The communication mode is now set. Next, in phase C, a message is sent and received. In phase D, control for sending the next page is applied. When the EOP signal (procedure end sign) is sent and the lVf CF signal (message confirmation signal) is returned, a line disconnection command DCN is sent in phase E to disconnect the line. The above-mentioned procedures include procedural controls such as error retransmission and 4-timeout, respectively.

Gl, G2 for facsimile transmission using analog signals
Similarly, other communication procedures are established for machines as well.

If the above-described procedure is followed, the timing at which the line message is sent will vary depending on the status of each facsimile terminal and the line status.

Therefore, when broadcasting messages to a plurality of facsimile receivers at the same time, the problem is how to absorb the difference in the timing of sending messages to the individual receivers. Therefore, in conventional broadcasting devices, the facsimile receiver is equipped with a waiting function, and when a certain signal is received during broadcast communication, the receiver remains in the same state and waits until the next step is reached. A method is adopted in which all facsimile terminals meet the same conditions before proceeding to the next step. Alternatively, only the facsimile terminals that advance at the same timing send out the broadcast communication, and the other terminals send out the repeat communication at different times. This conventional method has disadvantages, such as that it takes too much time to complete the broadcast communication, and that the broadcast communication is only possible with a special facsimile receiver. The above-mentioned methods are extremely inconvenient because the models of facsimile receivers that can be used for broadcast communication are limited to the same model.

An object of the present invention is to solve the above-mentioned conventional drawbacks, and to enable simultaneous broadcast communication even if a plurality of facsimile receivers, including receivers of different models, operate at different timings. It is possible to provide a facsimile distribution device.

The broadcasting device of the present invention is a facsimile broadcasting device for transmitting the same document to a plurality of facsimile receivers, and includes a memory having an area for storing an input message and an output buffer corresponding to a line, and an input message stored in the memory. a code conversion unit that sequentially reads out the code in units of a certain unit, converts it into an arbitrary code format, and writes it to the output buffer corresponding to the line, and a line control modem that is provided for the line and includes a G3 modem, a G2 modem, and a line control unit. a line interface section having a function of controlling the operation of the line control modem section and reading out an output buffer corresponding to the line and supplying the output buffer to the line control modem section; and a control section controlling the operation of each of the above sections. , the communication procedure corresponding to each receiver is executed for a plurality of lines, and the contents of the output buffers corresponding to the lines are independently output to the corresponding lines.

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 2 is a block diagram showing one embodiment of the present invention.

That is, in this embodiment, a message signal of a document to be relayed is inputted from the input terminal 1 and written into a predetermined area of the memory 200 via the input interface 10. The memory 20 is equipped with a plurality of areas for storing input message signals, for example, in the negative half place, and an output buffer corresponding to a line, and the input message signal stored in the memory 20 in the negative half place is, for example, one line. The data is read out minute by minute and converted into a code format corresponding to each line by the code converter 60, and then written to the output box 7a corresponding to the line in the memory 20. The code conversion and writing operations to the output buffer described above are performed independently for each line under the control of the control section 30. The operation of the control section 30 will be described later. The input message signal described above may, for example,
It is an original picture signal that has been binarized into "0" or "0", or it is an image signal that has been converted into a Modified Hamman code (MH code), which is a standard internal redundancy suppression code for facsimile signals. Also good.

On the other hand, the line interface section 40 and the line control modem section 5
0 is provided corresponding to the line. Line control modem section (
As shown in FIG. 3, the NCU modem 50 includes a line control section (NCU section) 500, a G3 modem 501, and a G2 modem 502. The NCU unit 500 is supplied via the line interface unit 40 (control unit 30
When a calling instruction (from ) is detected, the telephone number is sent out one digit at a time to the output terminal 2 while receiving the telephone number of the communication destination. When the NCU section 500 detects the completion of the connection, it notifies the control section 30 via the line interface section 40. The above operations are performed independently for each line.

Returning to FIG. 2, when the broadcast communication is started, the control unit 30
outputs a call request to the first line interface section 40,
The line interface section 40 receives the telephone number of the communication destination from the control section 30 and instructs the NCU modem section 5 to make an external call.

A plurality of telephone numbers of communication destinations are each received by a line interface section 40 corresponding to one line. Thereafter, telephone numbers are sent to each line independently from the corresponding NCU modem section 5 and 0. If the line connection is completed (as mentioned above)
When the CU modem section 5 is output from the outside and the control section 30 is notified, the control section 30 instructs the corresponding line interface section 40 to receive the GI-DIS signal (GI signals fl, G1
(The DIS signal is a digital recognition signal returned from the 03 aircraft.) Line interface section 40Ti'i, G3 modem 5 installed in NCU modem section 5 according to the above instructions
01 and G2 modem 502 are placed in a signal receiving state. G
The signals received by the G3 modem 501 and the G2 modem 502 are sent to the line interface section 40.

The line interface unit 40 monitors until the DIS signal is received from the G3 modem 501 and the GI signal is received from the G2 modem 502. When these signals are received, they are sent to the control unit 30 along with the received contents. Notice. When both the DIS signal and the GI@ signal are received normally, the control unit 30 controls the facsimile receiver [G3 machine and 02
It is judged that it has both functions of a machine. In the case of either one, it is determined that it is sufficient to have the functions of the other.

If the receiver has both functions, the communication procedure for the 03 machine is performed first, and if it is one of the machines, the corresponding communication procedure is performed. Here 77 Kushimi'J receiver is 0
A case where the device has three functions will be explained. In this case, the control unit 3 (lj, the corresponding line interface unit 40 determines the details of the facsimile IJ receiver function based on the DIS signal, and sends out a DC8 signal for specifying the receiving function.
instruct. After transmitting the DO8 signal through the line interface unit 40HG3 modem 501, and subsequently transmitting the TCP signal, the G3 modem 501 is put into the receiving state and the C
Wait for reception of FR signal. Upon receiving the CFR signal, the controller 30 is notified.

When the control unit 30 is notified of CFR reception from the line interface unit 40, it instructs the code conversion unit 60 to perform code conversion suitable for the line. In this case f1MH
Since the code should be sent, for example, if the input message signal stored in the memory 20 is an original picture signal, it is useful to instruct the conversion of the original picture signal into the MH code. The code conversion unit 60 reads out, for example, one line of the message signal stored in the memory 20 according to the above instruction, converts it into the specified code format (MI (code), and stores it in the memory 20.
Write to the output buffer corresponding to the line in 0. Transmission signals converted into code formats corresponding to the lines are written to the output buffers corresponding to each of the plurality of lines by the same operation as described above.

The line interface section 40 reads transmission number 4 from the output buffer corresponding to each memory 20 and transmits it to the facsimile receiver via the G3 modem 501 and the G2 modem 502. The four transmission numbers for one line are sequentially stored in the line-corresponding output buffers of the memory 20, and sequentially read out and transmitted. When one page of messages has been sent to the line, the control unit 30 instructs the corresponding line interface unit 40 to send an EOM or MPS signal if there is a serial message, and sends the last page of the message. If tjE
Instructs to send an OP signal and receive an MCF. The line interface unit 40H sends out the above signal, and notifies the control unit 30 when receiving the MCF signal.

In the case of the final page, when the control signal If30 receives the MCF signal, it instructs the line interface section 40 to send out the DCN signal. When the DCN signal is sent to all lines, the series of broadcast communications is completed. If there is a message signal for the next page, the message signal for the next page stored in the memory 20 is sent out in the same manner as above, and at the same time, a request for the message signal for the next page is sent via terminal 1, and the message signal for the next page is sent out. The message is received and stored in the memory 20.

The above is an explanation of the transmission to the 03 aircraft.
Even for two different types of terminals, the control unit 30 controls the line interface unit 40 etc. corresponding to each terminal according to the communication procedure according to the model of the terminal, and outputs corresponding to the lines in the memory 20. Similar processing can be performed by storing transmission data converted into a code to be sent to the line with σ in the cover sofa.

In other words, a plurality of facsimile receivers including different types of terminals are capable of receiving message signals at their own operating timings, and it is often necessary to align the timings with other receivers by queuing or the like. Some receivers complete reception sooner, while others complete reception later, but since transmission is done in parallel to all receivers, the receiver that is slowest receives reception. The circular communication can be completed at the same time as the completion. Broadcast communication can be performed more quickly than in the conventional method, which transmits data serially for each receiver or for each group. )03 aircraft.

It is also possible to perform broadcast communication in which different types of receivers, such as the 02 receiver, coexist.

As described above, in the present invention, an NCU modem section and a line interface section are provided for each line, and one person's messages are stored in the memory, and the signals sent to each line are sent to the line. At the same time, it is sequentially read from the above memory, converted into a code format suitable for the receiving side model, stored in an output buffer compatible with the network, and sent from the nuclear output buffer to the line via the line interface unit and NCU modem unit that are compatible with the line. Since the message is configured to be transmitted, messages etc. can be received by receivers connected to each line at their own timing. Therefore, if it is possible to carry out the actual broadcast communication to a plurality of facsimile terminals including different models, there is an advantage that the broadcast communication can be carried out quickly by parallel transmission.
