Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a facsimile communication system that can automatically notify a recipient of the receipt of a message.

(Conventional technology) Conventional technology in this field includes Osamu Murakami, "Facsimile: A New Communication Media" (■ Telecommunications Technology News, published April 1, 1980, pp. 174-17)
6).

According to the above-mentioned document, facsimile communication using a conventional facsimile communication network is performed according to the following procedure.

■When the calling party dials the special number rl 61J from the telephone, a second dial tone is returned from the local exchange (LS), and the calling party then dials the identification number (telephone number) of the called party.

■The LS detects the calling party's identification number (telephone number) and uses the calling party's trunk line electronic switching system (TS) together with the called party's telephone number.
-FX).

(2) Each TS-FX on the originating side and the receiving side performs a verification check to determine whether each facsimile machine (FAX) on the originating side and the receiving side is a subscriber of the facsimile communication network via a common line signal path.

■If the receiving party is not busy, the incoming fax will be sent from @Ts-FX.
After the telephone is activated without ringing, the incoming fax receives the image signal and the series of communications ends.

(Problem to be solved by the invention) By the way, when a conventional terminal device receives a call, it
It only emits the printer's hammering sound loud enough to be heard by people within a meter range, and it is generally used in offices and other offices where a regular telephone is installed for each employee or for every two or several employees. Even in laboratories, due to issues such as size and cost, facsimile terminal devices are often installed in each room, or several devices are installed in a dedicated room. In many cases, the terminal device and the recipient (recipient) who actually receives the message received by the terminal device are located far apart, so it is almost impossible for the recipient to confirm the receipt of the call. .

For this reason, conventionally, the sender and recipient had to contact each other by telephone just to send a message or confirm the receipt of a message, which required extra effort and telephone charges.
If such communication is not made, there is a problem in that there is no way of knowing when the message has arrived or not, which is very inconvenient when sending an urgent message.

SUMMARY OF THE INVENTION An object of the present invention is to eliminate the above-mentioned problems and provide a facsimile communication system that can automatically notify the recipient of the receipt of a message.

(Means for Solving the Problem) In order to achieve the above-mentioned object, the present invention includes a terminal device, a means for extracting a signal corresponding to a predetermined range of a communication from a received image signal, and a means for extracting a signal corresponding to a predetermined range of a communication from a received image signal; a talkie device which is provided with a means for extracting a telephone number, a means for automatically dialing the extracted telephone number with a preset special number after the end of the communication, and notifying an exchange of receipt of the message; facsimile communication comprising means for connecting the talkie device to a telephone with a subsequent telephone number when receiving a special number, and in which the telephone number of the receiver's telephone is written in a predetermined range of the message when sending the facsimile communication. We propose a method.

The NCU 41 performs control regarding outgoing and incoming calls, and also switches and connects the communication line between the telephone 3 and other circuits, that is, circuits within WFAXJ. The modem 42 demodulates the modulated and sent image signal.

The decoder 43 decodes the image signal encoded by the originating FAX 2 and converts it into the original image signal. The recorder 44 reproduces the image of the correspondence on recording paper in accordance with the image signal.

The timing circuit 45 generates a timing for extracting an image signal corresponding to a predetermined range on the front end side of the message from among the received image signals. The character recognition circuit 46 recognizes numbers, alphabets, etc. (hereinafter referred to as characters, etc.) from an image signal corresponding to a predetermined range on the front end side of the communication.

The memory 47 stores the recognized characters and the telephone number extracted therefrom. The automatic calling circuit 48 executes a calling operation based on a special number indicating a connection request for a talkie device, such as rlXYJ, and the extracted telephone number. A control circuit 49 controls each of the circuits according to a predetermined program.

The exchange 6 includes a communication path (network) 61, a calling register trunk 62, a talkie device 63, and a control device 64. The talkie device 63 generates a talkie notifying the receipt of the message, such as "Fax received." A control device 64 controls each of the circuits according to a predetermined program.

Although there are actually other circuits, only the portions related to the present invention will be described here.

The communication device 7 monitors the status of facsimile terminals and exchanges, and controls facsimile communication through the facsimile communication network. Note that if the communication between the originating fax and the terminating fax is out-of-area communication equivalent to a long-distance call, information is also stored.

FIG. 2 shows an example of a message with the recipient's phone number attached. A predetermined range 81 on the leading end side of the message 8, for example, a width of about 1 in the sub-scanning direction (! etc., a telephone number 82 such as 0Oo-ΔΔΔΔ” is written.

FIG. 3 shows the process flow 4c of the receiving (8 o'clock) process in the control circuit 49 of the incoming FAX 4, and FIG. The operation will be explained below according to these.

First, the sender sets a message with the telephone number of telephone 5 on the outgoing FAX 2, and sends the special number RL 61J and WFAX 4.
When dialing the telephone number (f!! phone number of telephone 3), if the limb FAX 4 is not busy, the originating FAX 2 and the receiving FAX 4 are connected via the communication path 61 and the communication device 7 by well-known exchange control. Then, the image signal of the message is sent from the originating FAX 2 to the destination FAX 4.

The image signal is input to the modem 42 via the NCU 41 and demodulated. When the control circuit 49 detects the beginning of the image signal from the output of the modem 42 (step sl), it starts the timing circuit 45 (step s2). ), and instructs the character recognition circuit 46 to start inputting data of the image signal decoded by the decoder 43 (step s3). At this time, the image signal is stored in a memory (not shown) in the character recognition circuit 46, and is also sent to the recorder 44, where the message is recorded.

After this, the time required to input the data of the image signal corresponding to the predetermined range on the leading edge side of the message has elapsed, and the timing circuit 4
When the end signal is received from 5 (step s4), the control circuit 49 causes the character recognition circuit 46 to recognize the characters in the image signal stored in its memory (step s5).

As a result of the character recognition, if there are any recognized characters (step S6), the control circuit 49 further extracts a telephone number from among them and temporarily stores it in the memory 47 (steps s, 7, s8, . s9). After that, the originating fax 2 and the arriving FA
When the communication with X4 is completed (step 510), the control circuit 49 sends the stored telephone number to the automatic calling circuit 48 and instructs automatic calling using the special number rlXYJ (step s11).

Note that, as a result of the character recognition process, if there are no recognized characters or the like, or if there is no telephone number among the recognized characters, the control circuit 49 ends the process.

On the other hand, the automatic calling circuit 48 automatically makes a call via the NCU 41, but when this is detected by a scanning device (not shown) of the exchange 6 (step apl), the control device 64
is controlled to connect the outgoing register trunk 62 to the incoming FAX 4 (step 5p2). When the automatic calling circuit 48 receives the dial tone from the calling register trunk 62 via the NCU 41, the automatic calling circuit 48 sends a dial signal of the special number rlXYJ to the NCU 4.
1. The dial signal of the special number rlXYJ is received by the calling register trunk 62, but the control device 64 detects the special number rlXYJ (step 5p3).
and instructs the calling register trunk 62 to send out the second dial tone (step 5p4).

When the automatic calling device 48 receives the second dial tone via the NCU 41, it sends a dial signal for the telephone number corresponding to the telephone 5 via the NCU 41, and ends its operation. The dialing signal for the telephone number is received by the calling register trunk 62 and notified to the controller 64.

The control device 64 receives the telephone number (step sp
5, sp6) and checks whether the telephone 5 corresponding to this telephone number is busy (step 5p7), and if it is not busy, controls the communication path 61 to send a ring trunk (not shown) to the telephone 5. Connect (step 5p8).

At this time, when the telephone 5, that is, the recipient of the aforementioned facsimile message responds (step 5p9), the control device 64
controls the communication path 61 and connects the talkie device 63 to the telephone 5 (step 10), and the talkie [fax has been received]. ” to the recipient. This allows the recipient to recognize the arrival of the message.

Note that if the telephone 5 is busy, the control bag B64 is restarted after a certain period of time (step SPH), and this is repeated a preset number of times.

Furthermore, although the explanation has been given by taking as an example a facsimile terminal device that has joined a facsimile communication network, it goes without saying that the present invention is not limited to this.

(Effects of the Invention) As explained above, according to the present invention, the telephone number of the recipient's telephone is recognized from the message, and after the communication is completed, the telephone number is automatically transmitted to the exchange, and the telephone number in the exchange is Since the device sends a text message to the receiver's telephone notifying the recipient of the receipt of the message, the receiver can recognize the arrival of the message, and therefore telephone communication between the sender and the receiver is possible. This eliminates the need to take calls, which eliminates extra effort and telephone charges, eliminates the risk of urgent correspondence being left unattended for a long time, and ensures that correspondence can be sent to recipients reliably and quickly. Therefore, the usability of facsimile communication services can be improved.
