Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a facsimile communication system, and particularly relates to a method for dealing with a situation such as a paper jam that makes it impossible to maintain communication. .

(Prior Art) As is well known, conditions that make it impossible to maintain communication in a facsimile communication system include, for example, a paper jam or paper shortage at a receiving terminal.

In addition, a facsimile machine (with the f system) that is set to allow communication only when the passwords match
This includes a situation where the passwords do not match.

Although typical facsimile communication systems have a means for detecting a state that makes it impossible to maintain communication, most of them do not have a means for notifying the other party's terminal of the detected state.

Therefore, if, for example, a paper jam occurs on the receiving terminal during communication, the transmitting terminal will not be able to detect this, and even though the receiving terminal has terminated the communication as an error, the transmitting terminal will I ended up having the mistaken impression that I had successfully sent the manuscript.

One method for solving this problem in this kind of conventional facsimile communication system is to send a message indicating the abnormality to the sending terminal immediately after an abnormality such as a paper jam occurs at the receiving terminal. was there.

However, in this method, after the communication ends, a call is made again and the message is sent, so it is difficult for the sending terminal that receives the message to determine which communication the message is for. In the end, the problem was not resolved.

Recently, a new method has been adopted in which, when a paper jam occurs at the receiving terminal, a telephone call is made to the transmitting terminal during the communication, and the ringing sound at that time notifies the occurrence of an abnormality.

However, even with this h-method, even if the operator at the sending terminal answers the call and picks up the receiver, the phone remains silent (it is not designed to send a voice message). Unless you are aware of this, you would not be able to tell when something is wrong.

As a result of not being able to detect such anomalies, the conventional facsimile communication system described above ends up blindly continuing to send data even though a situation occurs that makes it impossible to maintain communication, making it difficult to operate the system efficiently. The current situation was causing a hindrance.

(Problems to be Solved by the Invention) As described above, in the above conventional facsimile communication system,
Because we did not have an effective means of reliably notifying the other party's terminal of the occurrence of a condition that made it impossible to maintain communication, such as a paper jam, we regulated wasteful transmission when an abnormality occurred. However, there was a problem in that the operating efficiency of the system was inevitably reduced.

The present invention has been made in view of the above-mentioned circumstances, and it is possible to reliably notify the other party's terminal that a condition such as a paper jam that makes it impossible to maintain communication has occurred in the terminal, thereby eliminating unnecessary transmissions. The purpose of the present invention is to provide a facsimile communication system that can contribute to improving the operational efficiency of the system by regulating the system.

[Structure of the Invention] (Means for Solving the Problems) The facsimile communication system of the present invention includes a state detection means for detecting a state that makes it impossible to maintain communication in a facsimile terminal, and a state detected by the state detection means. a voice message storage means for storing a voice message corresponding to the above, and an optical call for voice calling to a facsimile terminal of a communication partner based on the state detected by the state detection means during execution of a prescribed control procedure. transmission means for transmitting the voice message read from the voice message storage means according to the state detected by the state detection means to the facsimile terminal of the communicating party that has responded to the voice call; and means.

(Function) In the facsimile communication system of the present invention, when the state detecting means detects a state that makes it impossible to maintain communication, during the communication, a voice is read out from the voice message storage means in response to the state. Since the message is transmitted to the facsimile terminal of the other party, the operator of the terminal receiving the message can recognize an abnormality on the other party's side in response to the communication, and can promptly resend the message according to the voice message. It becomes possible to take appropriate measures.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 is a block diagram showing an embodiment of a facsimile terminal (hereinafter simply referred to as a terminal) used in the facsimile communication system of the present invention, in which 1 is a main control section, 2 is a communication control section, 3 is a reading section, 4 is an encoding unit, 5 is a decoding unit, 6
7 is a recording section, 7 is a state detection section, 8 is a voice memory, 9 is a communication circuit, and 10 is a handset.

In FIG. 1, the state detection unit 7 includes a paper jam detector 70.
It is configured to include a paper shortage detector 71 and a password verifier 72.

Here, the paper jam detector 70 uses, for example, a microswitch that generates an output in response to the passage of paper, and a counter that monitors the output generation period, and detects a paper jam when the output generation period is longer than the required time. It can be composed of something that makes a judgment as follows.

Further, the paper shortage detector 71 can be constructed by using a similar microswitch, which senses when paper runs out, and thereby generates an output indicating the paper shortage.

Furthermore, the password verifier 72 stores a preset password, and when the password input from the other party's terminal in response to a communication request matches the set password, a signal indicating that the communication is permitted is generated. It can be configured by outputting .

By using a terminal having the state detection section 7 having such a configuration, the facsimile communication system boom of the present invention can detect each of the states such as paper jam, paper shortage, and password mismatch that may occur in the terminal.

Further, in the terminal according to the present invention, voice messages as shown in 1 to 3 in FIG. 2 are set in advance in response to each of these states, and are stored in the voice memory 8.

Now, in the terminal of this facsimile communication system,
Under the control of the main control section 1, a prescribed facsimile communication is performed via the communication control section 2 according to the restriction procedure as shown in FIG.

First, the transmitting side terminal (indicated by T8) receives the receiving side 4:terminal (RX
f digital command signal O in response to the non-standard function identification signal NSF and digital identification signal DIS received from
CS returns the non-standard function setting signal NSS.

Subsequently, the transmitting terminal sends a training check signal TCP to the receiving terminal to perform a line training check.

In response, the receiving terminal performs a so-called training check to determine whether or not the training check signal TCP has been received normally, and if it recognizes that the training check signal TCP has been normally received, the line quality 8 is accepted by the sending terminal as a good one.
A quasi-TsFi recognition signal CFR is returned.

On the other hand, when the transmitting terminal receives this reception (8 preparation confirmation signal C[R), it starts transmitting the image information PiX for the first time.

Thereafter, when the transmitting terminal finishes transmitting one page of image information PIX, it transmits a multi-page signal MPS to the receiving terminal only if there is image information Pix to be transmitted next.

Furthermore, the transmitting terminal acknowledges the message confirmation PL (5RMCF) from the receiving terminal in response to this multi-page signal MPS, and transmits the next page's image information Pix to the receiving terminal.

Then, when the transmission of the image information Pix of the page is finished,
Only when there is no image information tlIPix to be transmitted next, a procedure end signal EOP indicating the end of the procedure is sent to the receiving terminal.

Thereafter, the transmitting terminal waits for a response of the message confirmation signal N4CF from the receiving terminal in response to the ilQ procedure end signal EOP, and then sends a disconnection command signal DCN to disconnect the line.

It is assumed that while communicating according to the υ11!1 procedure, a paper jam is detected by the paper jam detector 70 while the receiving terminal is receiving the first page image information Pix.

In this case, the control procedure changes from the state shown in FIG. 3 to the state shown in FIG.

When a paper jam is detected by the paper jam detector 70, the main control unit 1 at the receiving terminal, based on the detection output, interrupts the procedure in response to the multi-page signal MPS received from the transmitting terminal. Return PIP.

In response to this procedure interruption confirmation signal PIP, the sending terminal makes a telephone call through the communication control section 2 and the telephone call circuit 9 under the control of the main control section 1.

When the operator responds to this telephone call and takes the handset 10 off-hook, the transmitting terminal sends a procedure interrupt MPS signal PR indicating this to the receiving terminal.
Send I-MPS.

At the receiving terminal that receives this, the main control unit 1 reads out from the voice memory 8 the voice message (1 in FIG. 2) corresponding to the paper jam detected by the paper jam detector 70 at this time, and transmits it. It is sent to the transmitting terminal through the control unit 2.

As a result, the voice message is played back from the handset 10 at the sending terminal, so the operator can take measures such as suspending transmission until the paper jam is removed, or retransmitting after the paper jam is removed, according to the voice message. This makes it possible to control wasteful communication.

Similarly, for example, receive [t! If a paper shortage is detected by the paper shortage detector 71 while receiving the image information Pix of the first page at the I terminal, the procedure is interrupted from the sending terminal M P S
(After receiving # PRI-MPS, the main control unit 1 reads out the voice message from the voice memory 8 and selects the voice message corresponding to the occurrence of paper shortage (2 in Fig. 2) as the voice message to be transmitted.) It also becomes possible to restrict wasteful transmission from the sending terminal when the paper runs out.

By the way, in addition to the above-mentioned normal communication, this type of facsimile communication system also performs password communication in which communication is permitted only when preset passwords between the sending and receiving terminals match. You can also do it.

The control procedure related to this password communication is as shown in FIG.

That is, in the first stage of this control procedure, the sending 1Δ side terminal sends a digital command signal in response to the non-standard separate identification signal NSF and digital identification signal DIS arriving from the receiving side 0=end, as in the normal control procedure. The DC81 non-standard function setting signal NSS is returned, and then the training check signal TCF is sent out.

At this time, the receiving terminal receives the unmarked 2v condylar function identification signal NSF.
In response to this notification, the sending terminal sends a non-standard capability setting signal NSS.
sends the password entered on the own terminal.

As a result, in the receiving terminal, this password is received by the communication control section 2 and further taken into the main control section 1.

Is this the owner of the receiving terminal? The IIJ 111 unit 1 compares the password imported at this time with a preset password using the password verifier 72 of the state detection unit 7, and determines whether or not they match.

When it is determined that the partner's passwords do not match, the main control unit 1 responds to the training check signal TCP received from the transmitting terminal with a procedure interruption confirmation signal PIP.

In response to this procedure interruption directing signal @PIF, the sending terminal makes a telephone call through the communication IT, II control section 2, and telephone call circuit 9 under the control of the main control section 1.

When the operator responds to this telephone call and takes the handset 1o off-hook, the transmitting terminal sends a procedure vlIEOP signal PRI-E to the receiving terminal.
Send OP.

At the receiving terminal that receives this procedure interruption EOP signal PRI-EOP, the main control unit 1 reads out the voice message (3 in Figure 2) corresponding to the state where the passwords do not match from the voice memory 8, and controls the communication. The data is sent to the transmitting terminal through section 2.

This voice message allows the operator of the transmitting terminal to know about the discrepancy in the passwords, so that he can promptly take measures such as correcting the passwords.

Furthermore, as a communication that can be performed using the facsimile communication system 7 of the present invention, polling password communication is possible.
There is something.

In this polling password communication, the calling terminal requests the called terminal to send image information Pix, and in response to this request, the called terminal sends the image information Pix that has been accumulated up to that point. A unique password is used as an index to determine whether or not to allow this transmission.

The control procedure related to this polling password communication is as follows:
The result will be as shown in the figure.

In other words, this control procedure is based on the calling terminal (for convenience of explanation,
from the called terminal (indicated by the same TX as the transmitting terminal) to the called terminal (indicated by the same TX as the transmitting terminal)
It begins by dialing to the receiving terminal (accepted on the same RX).

In response to this dialing call, the called terminal sends a non-standard 1jlt capability identification signal NSF to the calling terminal.
, a digital identification signal DIS is sent, and the calling terminal that receives this responds to the called terminal with a digital transmission command signal DTC1 and a non-standard low-performance command signal NSC.

At this time, the non-standard function command signal NSC includes a password related to polling password communication, and this is taken into the main control section 1 via the communication control section 2 in the called terminal.

Here, the main control unit 1 of the called terminal compares the password retrieved at this time with the password preset for polling password communication using the password verifier 72 of the status detection unit 7, and if they match. Make a judgment as to whether or not.

When it is determined that the partner's passwords do not match due to this TJ1 disconnection, the main control unit 1 immediately sends a procedure interruption offer signal PIP to the calling terminal.

In response to this procedure interruption offer signal PIP, the calling terminal makes a telephone call through the communication control section 2 and the telephone call circuit 9 under the control of the main control section 1.

When the operator responds to this telephone call and takes the handset 10 off-hook, the calling terminal sends a procedure interrupt EOP signal PRI-EOP to the called terminal.

During this procedure [! In the called terminal that receives the 1EOP signal PRI-EOP, the main control unit 1 retrieves from the voice memory 8 a voice message (second
3) in the figure is read out and sent to the calling terminal through the communication control unit 2.

This voice message allows the operator of the calling terminal to
It is possible to know if the passwords do not match, and take measures such as correcting the password and calling again.

As described above, in the facsimile communication system of the present invention, an abnormality can be reliably recognized by the voice message broadcast from the other party's terminal, and measures can be taken to stop unnecessary transmissions as soon as possible.

Furthermore, in the present invention, this voice message is broadcast to the other party's terminal using a control procedure that conforms to the standard procedure, so it is possible to receive the service regardless of the manufacturer.

[Effects of the Invention] As explained above, according to the facsimile communication system of the present invention, the occurrence of a condition that makes it impossible to maintain communication is notified by a voice message corresponding to the condition during the communication. As a result, the terminal that receives this notification can take measures such as immediately stopping unnecessary transmissions in accordance with this voice message, which has the great advantage of dramatically improving the operational efficiency of the system. .
