0001

[Industrial Application Field] The present invention is connected to a private branch exchange,
The present invention relates to a communication terminal device equipped with a facsimile function.

0002

2. Description of the Related Art In recent years, with the spread of communication networks and the reduction in prices of devices, various communication devices such as facsimile machines have become widespread.

[0003] A facsimile machine as a conventional communication terminal device will be explained below with reference to the drawings. FIG. 5 is a simple block diagram of a conventional facsimile machine. 1 is a network control device that connects a telephone network and a communication terminal; 2 is a data transmitting and receiving unit that transmits and receives document image data (image data); 4 is an output unit that outputs received document image data;
is a communication control unit that controls the entire device. In FIG. 5, the received document image data is held in a state in which it is output from an output unit 4 such as a printer. Therefore, the only way to know that a message had been received was for someone to go to the facsimile machine and check. As described above, in the conventional system, even if a document is received, it is difficult for a recipient located far away from the facsimile to immediately confirm receipt.

[0004] In order to solve this problem, the following system has been proposed. A simple block diagram of this system is shown in FIG. Hereinafter, parts having the same functions as those in FIG. 5 are denoted by the same reference numerals, and explanations thereof will be omitted. Reference numeral 5 denotes a voice message sending unit that sends a voice message onto the line. In FIG. 6, the operation of receiving document data and outputting it from the printer which is the output unit 4 is the same as the operation of the conventional system of FIG. 5, but the following points differ from the conventional system. That is, after the line is connected, the communication control unit uses a non-standard command in phase B of the facsimile procedure to receive the extension number of the destination from the destination device of the source. Figure 7
is a flowchart showing the state. This figure shows a case where the calling party is the transmitting terminal and the called party is the receiving terminal. When the called side enters phase B, it sends a called station identification signal (CED signal).
, and subsequently sends out a non-standard function identification signal (NSF signal) and a digital identification signal (DIS signal). In the frame of the NSF signal, the transmission source device is requested to transmit the extension number of the transmission destination. After receiving these signals, the transmitter sends a non-standard function setting signal (NSS).
) signal and a digital command signal (DCS signal). Information on the extension number of the destination is transmitted in the frame of the NSS signal. In the above procedure, if the sender does not know the destination's extension number, the extension number will not be sent.
It operates in the same way as a conventional facsimile machine.

[0005] After the facsimile call ends, the receiving terminal connects to the destination extension using the extension number, and then the voice message sending unit 5 notifies the extension that the facsimile document has been received. Send a voice message.

FIG. 8 is a diagram showing the frame structure of the NSF signal and NSS signal, which are non-standard commands. Both the NSF signal and NSS signal are HDLC (high level
Only the information fields in the data link control) format are shown. NSF in the figure
is a 1-byte code of 00000100b, CCITT
The members code is a 1-byte code of 00000000b, the extension number transmission request code is a 1-byte code obtained after applying to the administration, and the NSS is a 1-byte code of X1000100b (X in the code is CCITT recommendation T.30
If the extension number has N digits, the extension number consists of an N-byte character code.

FIG. 9 is a block diagram of a conventional facsimile apparatus having the configuration shown in FIG. 6 connected to a telephone or the like through a private branch exchange. 6 is a private branch exchange, 7 is a facsimile machine having the configuration shown in FIG. 6, and 8 and 9 are telephones connected to the private branch exchange. In this case, facsimile machine 7
Since it is necessary to have a direct connection to an outside line and to be able to use an extension telephone, the direct in feature of the exchange must be used. In FIG. 9, facsimile device 7 that has received the facsimile document makes a call to the destination (extension telephone 8 or 9) using the extension number of the destination sent from the calling party after the facsimile call ends. , after connecting the line,
The voice message sending unit 5 notifies the user that the facsimile document has been received using a voice message or the like. As described above, it is possible to simultaneously receive a document and confirm the receipt, but the person who received the reception notification had to go to the facsimile machine to retrieve the facsimile document.

[0008]

[Problem to be solved by the invention] In the above conventional configuration,
When a facsimile document is received from a sending device, information regarding the extension telephone number of the destination is received from the sending device, and after the facsimile call is completed, a call is made to the destination to confirm that the facsimile document has been received. The only notification was through voice messages, etc. In this case, there is a problem in that the person receiving the facsimile document must go to the facsimile machine to retrieve the facsimile document.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned conventional problems and to provide a means by which a recipient of a facsimile document does not have to go to the facsimile machine that received the document to retrieve the document.

0010

[Means for Solving the Problems] In order to achieve the above object, a communication terminal device of the present invention includes a network control device for connecting to a telephone network, a data transmitting/receiving section for transmitting and receiving document image data, and a data transmitting/receiving section for transmitting and receiving document image data. A data storage unit that stores document image data; a communication control unit that controls the entire device; and a data transmission unit that transmits data from the source device during a facsimile procedure via the data transmission and reception unit either alone or under the control of the communication control unit. After receiving the extension number information and ending the facsimile call, information is exchanged with the destination of the extension number, and if it is determined that the destination terminal device is equipped with a function to receive document image data, the extension number is and a connection destination terminal automatic determination section that transfers the received data stored in the data storage section to the destination terminal device using the number.

[0011] Also, if necessary, an output section for outputting to a printer, a voice message section, and an extension number of the destination from the sending device during the facsimile procedure, either alone or under the control of the communication control section, via the data transmitting/receiving section. receive information,
After the facsimile call ends, information is exchanged with the terminal device of the extension number, and if the destination terminal device is a telephone that does not have the function of receiving document image data, the received data stored in the data storage section is and a connected terminal automatic determination section that outputs to the output section and sends a voice message from the voice message section to the destination telephone using the extension number.

0012

[Operation] With the above configuration, the present invention allows a device connected to the destination extension number received from the source device to receive document image data (having a facsimile function).
If it is a terminal device, the document image data can be transferred to the terminal device, so the person receiving the facsimile document does not have to go to the facsimile device that received the facsimile document to retrieve it. If the device connected to the destination's extension number received from the sender's device is a telephone, the document is output to the printer, a voice message is sent to the telephone, and the person receiving the facsimile document receives the call at the same time. You can also check.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A communication terminal device according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a block diagram of a facsimile machine A18 which is a communication terminal device according to an embodiment of the present invention. In the facsimile machine A18, 10 is a network control device for connecting the terminal to the telephone network, 11 is a data transmitting/receiving unit that transmits and receives document image data, 13 is an output unit that outputs the received document image data, and 14 is a line 15 is a data storage unit that stores document image data; 16 is a device that automatically determines whether or not a terminal device connected to the line is a communication terminal equipped with a facsimile function; Connection destination terminal automatic determination unit, 1
2 is a communication control unit that controls the entire device.

[0014] Consisting of the above-mentioned components, the mutual relationship and operation thereof will be explained below. After the line is connected, the communication control section 12 of the facsimile machine A18 uses non-standard commands in phase B of the facsimile procedure to control the other party's device. Receive the extension number of the destination (transfer destination) from. To explain using the flowchart of FIG. 7, which is common to the conventional example, the figure shows a case where the calling side becomes the transmitting terminal and the called party becomes the receiving terminal. When the called side enters phase B, it transmits a called station identification signal (CED signal), and subsequently sends out a non-standard function identification signal (NSF signal) and a digital identification signal (DIS signal). Said NS
Requests the sending device to send the destination extension number in the frame of the F signal. After receiving these signals, the transmitting side sends out a non-standard function setting signal (NSS) signal and a digital command signal (DCS signal). Said N
The extension number of the destination is transmitted in the frame of the SS signal. In the frame structure of the NSF signal and NSS signal, which are non-standard commands, shown in FIG.
Only the information fields in the ink control) format are shown. NSF in the diagram is 0000010
0b 1-byte code, CCITT members code is 00000000b 1-byte code, extension number transmission request code is 1-byte code obtained after applying to the competent authority, N
SS is a 1-byte code of Ru. In the above procedure, if the sending side does not know the extension number of the destination, no information regarding the extension number is sent, and the facsimile operates as a conventional facsimile. What is different from the conventional example during the facsimile call is that the document image data received from the other party's device is temporarily stored in the data storage section 15.

FIG. 2 shows the flow of processing after a facsimile call ends when information about the extension number of the destination is received from the other party's device that is the source of the facsimile document.

First, a call is made to the terminal device having the above-mentioned extension number. (Step 2-1) Next, the connection response of the partner device in response to the calling operation is monitored for T1 time (Step 2-2). T1 is the waiting time for a connection response from the partner device. This time (T1 seconds) is set in advance. If the line is connected within T1 seconds, the connected terminal automatic determination unit 16 automatically determines whether the connected terminal device is a terminal device equipped with a facsimile function (step 2-5). . If the other party's device does not answer the first call, the set number of redials (T
2 times), perform the calling operation again (Step 2-
3). If there is still no connection response, line disconnection processing is performed (step 2-4). After that, the data storage section 15
The received data stored in is outputted from the printer which is the output unit 13 (step 2-12).

FIG. 3 shows the flow of processing in the connection destination terminal automatic determination unit 16 (step 2-5). This diagram is
A flowchart is shown when the facsimile procedure is performed using a binary code procedure. After the line is connected, the answer tone of the connected terminal is detected for 3 seconds. (Step 3-1
). If an answer tone is detected during this time, there are two possible connection destination terminal devices: a facsimile terminal and a personal computer communication terminal. Next, in order to identify the two, the receiving side (connection destination)
HDLC format flag (0) sent from the device
1111110b) for T3 time (35+5 seconds) (Step 3-2). If said flag is detected,
It is determined that it is a facsimile device (step 3-3). If the flag is not detected, it is determined that it is a personal computer communication terminal (step 3-4). If no answer tone is detected, there is a possibility that the other party's terminal device is a telephone or a facsimile machine set to manual reception. Therefore, in order to distinguish between the two, for example, the following audio guidance is sent out (step 3-5). "A message has been received on the facsimile machine. If you are using a fax, please connect to the facsimile machine. If you are using a telephone, please disconnect the line." After sending the voice guidance,
In order to detect whether the receiving side device has disconnected the line, polarity reversal detection is performed for T4 hours (step 3-6).
. The time T4 is set to a time sufficient for the operator on the receiving side to perform the above operations. If no polarity reversal is detected within the T4 time, a CNG (calling tone) signal is sent (step 3-7), and an HDLC format flag (01111110b) sent from the receiving device according to the binary code control procedure. ) is detected (Step 3
-8). If the flag is detected, the destination terminal is determined to be a facsimile machine (step 3-9). If no flag is detected, line disconnection processing is performed (step 3-11). If polarity reversal is detected, the connected terminal device is determined to be a telephone (step 3-10).

Next, a case will be described in which the automatic connection destination terminal determination section determines that the connection destination terminal is a communication terminal device equipped with a facsimile function. (Step 3-2
) and (step 3-9),
Transfer the received data stored in the data storage unit 15 to the connected communication terminal device according to the facsimile procedure (
Step 2-6 in Figure 2). After the facsimile procedure is completed, line disconnection processing is performed (step 2-7).

A case will be explained in which the automatic connection destination terminal determination section 16 determines that the connection destination terminal is a telephone. The voice message transmitter 14 transmits a voice message on the line notifying that the facsimile document has been received (step 2-8). After sending the voice message, line disconnection processing is performed (step 2-9). Thereafter, the received data stored in the data storage section 15 is outputted from the printer of the output section 13 (step 2-10).

[0020] If the connection destination automatic determination unit 16 determines that the connection destination terminal is a personal computer communication terminal, line disconnection processing is performed (step 2-11).

FIG. 4 is a block diagram when a facsimile machine, which is a communication terminal device according to one embodiment of the present invention, is connected to a telephone, a communication terminal device, etc. through a private branch exchange. In the figure, 17 is a switchboard, 18 is a facsimile machine A in this embodiment, 19 is an extension telephone, 20 is a communication terminal device with a facsimile function, and 21 is a conventional facsimile machine B.
It is.

[0022] In this case, the facsimile machine A18 has a direct connection to an outside line and must also be used as an extension telephone, so it is directly connected to the private branch exchange. In FIG. 4, it is assumed that facsimile device A18 receives a facsimile document. Facsimile machine A1
If the extension number of the transmission destination is received from the transmission source facsimile machine (not shown) during the facsimile procedure, after the facsimile call is completed, 8 performs a calling operation to the terminal device having this extension number.

If this extension number is a communication terminal device 20 or 21 having a facsimile function, after the line is connected, the connected terminal automatic determination unit 16 determines that it is a facsimile device according to the processing flow shown in FIG. Accordingly, the received document image data is transferred to the communication terminal device 20.
Or forward to 21. If the extension number corresponds to extension telephone 19, a voice message is sent to notify that the facsimile document has been received.

As described above, if the terminal device connected to the extension number of the communication destination received from the communication side device is a communication terminal device with a facsimile function, the person receiving the facsimile document cannot receive the facsimile document. A facsimile document can be received using a nearby facsimile without having to go to the receiving facsimile device A18 to retrieve it.

[0025] The automatic judgment unit 16 performs the transfer after determining the contents of the communication terminal at the destination, and the operation of making a voice announcement when the other party is a telephone.
The communication control section 12 may take over the entire control, or the communication control section 12 may take over and perform the operations there.

Further, the communication control unit 12 and the automatic connection destination terminal determination unit 16 may be configured with separate hardware, or may be implemented entirely on software.

[0027]

[Effects of the Invention] As explained above, according to the present invention,
When a facsimile document is received by a facsimile machine that is remote to the facsimile document recipient, the facsimile document is sent to the facsimile document recipient using the extension number of the destination received from the sender's device. If the destination extension number is a communication terminal with facsimile function, the facsimile document can be directly received by the communication terminal at hand. It is possible to provide a highly practical receiving terminal device that eliminates the need to go to the facsimile device that received the call to retrieve the document, and that allows immediate reception of facsimile documents and confirmation of reception.
