BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication terminal device connected to a private branch exchange, such as a facsimile machine, which transmits images.

0002

2. Description of the Related Art In recent years, communication networks have become more widespread and devices have become cheaper, and various communication devices such as facsimile machines have become more 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 text 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. Figure 9 is Figure 5
This is a configuration diagram when a conventional facsimile device having the configuration shown in FIG.
is a telephone connected to a private branch exchange. In this case, the facsimile machine 1 of this embodiment is connected to the outside line by direct in of the exchange. 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. Figure 6
In this system, the operation of receiving document data and outputting it from a printer serving as an output unit is the same as that of the conventional system shown in 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. FIG. 7 is a flowchart showing this 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 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 NSF
Requests the source device to transmit the destination extension number in the signal frame. 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 NS
Information on the extension number of the destination is transmitted in the S signal frame. In the above procedure, if the sending side does not know the extension number of the destination, the extension number is not sent and the facsimile operates in the same way as a conventional facsimile machine.

[0005] After the facsimile call ends, the receiving terminal connects to the destination extension phone using the extension number, and then sends a voice message from the voice message sending unit to the extension phone notifying that the facsimile document has been received. Send a 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, since the facsimile machine 7 must be able to connect directly to an outside line and also use an extension telephone, the direct-in function 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 the line is connected, the voice message sending unit 5 notifies that the facsimile document has been received.
Notify using voice messages, etc. 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.

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 an extension number information storage unit that stores extension numbers and attributes of the device; and 12 is a control unit for the entire device. This is a communication control unit that performs

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

[0015] In this case, the facsimile machine A18 must be able to connect directly to an outside line and also use an extension telephone, so it is connected directly to the private branch exchange.

Consisting of the above-mentioned components, the mutual relationship and operation thereof will be explained below. After the line is connected, the communication control unit 12 of the facsimile machine A18 uses non-standard commands to control the other party's device in phase B of the facsimile procedure. 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 the facsimile call ends when information about the extension number of the destination is received from the other party's device.

First, the extension number information storage section 16 is referred to. Next, it is determined whether the device connected to the extension number of the transmission destination (transfer destination) is a telephone or a communication terminal device having a facsimile function. FIG. 3 shows the contents stored in the extension number information storage section. As shown in the figure, extension numbers and attributes of their devices are stored as a table in one-to-one correspondence. In the figure, a communication terminal device with attribute 1 is a communication terminal device having a facsimile function. Therefore, by referring to this content, it can be seen that when the extension number attribute is 0, it is connected to an extension telephone, and when the attribute is 1, it is connected to a communication terminal device having a facsimile function.

A case will be explained in which the destination device with extension number 2003 is a communication terminal device 20 having a facsimile function. First, a call is made to the destination extension number 2003. After the line is connected, the received data stored in the data storage unit 15 is transferred to the communication terminal device according to the facsimile procedure. and,
After completing the fax procedure, disconnect the line. If the other party's device does not respond to the calling operation even after T1 time, the line is disconnected. T1 is the waiting time for a response from the partner device, and this time is set in advance.

[0020] Next, a case where the device with destination extension number 2002 is a telephone will be explained. First, the data storage section 15
Output the received data stored in the printer from the printer. Next, a call is made to extension number 2002. After the line is connected, the voice message sending section 14 sends a voice message to the line notifying that the facsimile document has been received. After sending the voice message, disconnect the line. If the other party's device does not respond to the calling operation even after T1 time, the line is disconnected.

[0021] If the other party's device does not respond to the first call, it is also possible to perform the calling operation again.

To summarize the above, in FIG. 4, when facsimile device A18 receives a facsimile document,
If this facsimile device receives information on the extension number of the destination from the source facsimile device during the facsimile procedure, after the facsimile call ends, the facsimile device refers to the extension number information storage unit 16 and determines whether the destination has a facsimile function. If the communication terminal device 20 or 21 is a communication terminal device 20 or 21, the received document image data is transferred to the communication terminal device according to the facsimile procedure. If the destination is the extension telephone 19, the facsimile device A18 outputs the facsimile document to the printer and notifies the telephone 19 of this fact through a voice message.

As described above, if the terminal device connected to the destination's extension number received from the sending 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 at a terminal device at hand without having to go to the receiving facsimile device A18 to retrieve it.

[0024]

[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 allows immediate reception of facsimile documents and confirmation of reception.
