Abstract

PURPOSE:To recognize reception refusal and its opposite party by informing the reception refusal from an incoming call side to an outgoing call side when outgoing call side identification information is not fitted in a condition set in advance, and displaying or recording the interruption of communication due to the failure of setting the condition at a reception side with the outgoing call side. CONSTITUTION:A transmission side issues a call to the opposite party, and the reception side sends a CED signal, an NSF signal, a CSI signal, and a DIS signal sequentially. Next, the transmission side sends an NSS signal, a TSI signal, a DCS signal, and a modem training signal sequentially. When no communication function designated by the transmission side is provided on its own device, the fact of the reception refusal is informed by transmitting the NSF signal when noncoincidence is obtained in a received ID code, and it is stored in a system memory 9. Next, a line is disconnected by sending a DCN signal. The transmission side immediately disconnects the line when the reception refusal is informed, and records and outputs those information as a reception refusal report with a plotter part 4.

Description

[Detailed description of the invention] [Industrial application field] The present invention relates to a facsimile device.

[Conventional Techniques] Normal 63 standard facsimile machines communicate in accordance with CCIT Recommendation 7.30. As a basic function of this transmission procedure, after the start of communication, the calling party notifies the called party of the calling party's identification information such as a telephone number using a TSI signal6.In addition, as an optional function, NSS
RTI (Remote Termina)
l Identification) There is a function to notify the name of the calling party as information.

Furthermore, an incoming call restriction function is known that identifies the other party when a call is received, receives image information only if preset conditions are met, and stops communication if the conditions are not met.

One way to restrict incoming calls is to register the recipient's phone number and name in advance in the facsimile machine, and when receiving a call, the content received in the TSI signal or RTI information and the registered phone number are sent to the facsimile machine. For example, if the two match, the image information is received.

Another method is called a closed connection function. In this case, the operator registers the same ID code in advance in each facsimile machine with which communication is to be performed. Then, the calling side facsimile machine sends a ■0 code at the start of communication, and the called side receives image information if the received In code matches the registered ID code. be.

[Problem to be Solved by the Invention] By the way, when the called side interrupts communication without receiving image information due to the incoming call restriction function as described above, immediately after receiving the modem training signal in the transmission control procedure, A DCN signal was sent to notify that the line had been disconnected, and communications were to be terminated.

In addition to the above-mentioned cases, the called side may send out the DCN signal in this manner, for example, when there is a large data error due to deterioration of the line condition.

However, conventionally, the calling side operator receives the DC from the called side.
There was a problem in that when an N signal was received, it was not possible to know why the other party had stopped communication. For this reason, there have been cases where the user thinks that communication can be established by re-transmitting, and performs a useless re-transmitting operation.

Further, there is a problem in that the operator on the receiving side cannot know the recipient whose facsimile machine refused to receive the image and stopped the communication.

The present invention solves the above problems and allows the calling operator to
To provide a facsimile machine which allows a called side to know reception rejection based on destination condition settings, and allows an operator on the called side to know a called party who has refused reception.

[Means for Solving the Problem] To this end, in the first invention, the called side is configured such that the calling side identification information, which is the IO code and TSI information received from the calling side, conforms to preset conditions. If not, the calling party is notified of the refusal of reception, and upon receiving this notification, the calling party is required to display or record that the communication has been discontinued due to violation of the setting conditions on the receiving party. I have to.

Further, in the second invention, when the called party cancels communication based on the condition determination of the received calling party identification information, the called party displays or records the calling party identification information. [Operation] According to the first invention, the operator on the calling side can know that reception is rejected due to the setting of destination conditions on the called side, and according to the second invention, the operator on the called side can know that reception has been rejected due to the setting of the other party's conditions on the called side. You will be able to know the other party. [Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. FIG. 1 shows a block diagram of a facsimile machine according to an embodiment of the present invention. In the figure, a system control section 1 has a built-in CPU and controls each section of the apparatus to execute predetermined communication operations. Operation display section 2
The device is equipped with operation keys and a display, and allows the operator to perform various operations and displays the operating status of the device. The scanner section 3 reads the original image and extracts image information, and the plotter section 4 records the received image on recording paper.

The communication control unit 5 controls the transmission of image information, and the modem 6 transmits and receives procedure signals for transmission control, as well as modulates and demodulates the image information. The network control device 7 performs predetermined call/receive operations on the telephone line.

The encoding/decoding unit 8 encodes image information to be transmitted and decodes received image information. The system memory 9 stores various information set by the operator and history information such as recipients who have refused reception.

The system path 10 is a signal line through which the above-mentioned parts exchange control signals and data between each other.

With the above configuration, the facsimile machine of this embodiment has the above-mentioned incoming call restriction function. Therefore, the operator
Register the IO code and the telephone number of the recipient to whom reception is permitted in advance by performing a predetermined registration operation on the facsimile machine. As a result, one registered ID code and an arbitrary number of reception-permitted destination telephone numbers are stored in the system memory 9, as shown in FIG.

The ID code is the same code that is registered for each facsimile machine in a group that communicates with each other, and becomes valid when a call is received when the facsimile machine is set to the closed connection mode.

Further, the above-mentioned reception-permitted destination telephone number becomes valid when the incoming call restriction mode is set and an incoming call is received.

In addition, this facsimile device transmits own station identification information such as a telephone number using a CSI signal or a TSI signal in the 5 transmission control procedure using known technology, and also transmits NS identification information such as a telephone number.
R of own station name etc. transmitted by F signal or NSS signal
TI (Remote Terminal Identity)
In addition to having the function of transmitting (ficatin) information,
It is assumed that the transmission information is stored in advance.

Next, communication operations between facsimile machines in this embodiment will be explained. In addition. The receiving operator sets the incoming call restriction mode and the closed connection mode as necessary by performing predetermined operations.

Figure 3 shows the operation of the sending facsimile machine, and Figure 4 shows the following:
Each figure shows the operation of the receiving facsimile machine.
That is, first, the sending side calls the other party (Fig. 3, process 101). When the receiving side receives a call (Fig. 4, processing 201)
), a predetermined pre-message transmission control procedure is executed between the two (process 202). Figure 5(a) shows this procedure, in which the receiving side receives CED signals, NSF signals, CSI signals.
The signal and DIS signal are sent out sequentially. At this time. N
The RT'I information is transmitted using an SF signal, and the receiving side's telephone number, etc. is transmitted using a CSI signal.

Next, the transmitting side sends the NSS signal, TSI signal, DCS
Sequentially send out signals and modem training signals.

At this time, if a special communication function is specified. NSS
Notify the designation with a signal. Also, with that NSS signal,
The ID code and RTI information are transmitted, and the telephone number of the transmitting side is transmitted as a TSI signal.

On the receiving side, if the modem training was successful (processing 2
03 Y), it is determined whether it is possible to execute the communication function specified by the sending side (process 204). Examples of this communication function include confidential transmission and relay transmission. Here, if the own device has the designated function and is communicable (Y in process 204), then it is determined whether the closed connection mode is set (process 205).

Assuming that the closed connection mode is currently set (Y in process 205), the IO code received in the above NSS signal is compared with the registered IO code (process 206).
. If the two match (Y in process 206), then check whether the telephone number of the other party received in the above TSI signal is designated as the reception-permitted telephone number stored in the system memory 9. Determine (processing 207). Here, if the destination is specified as a receiving permission destination (process 207
(Y), transmits the NSF signal.

Figure 6 shows 1 byte of notification information set in this NSF signal, where the 1st bit is the training result, the 2nd bit is the TSI signal verification result, and the 3rd bit is the I/O signal.
As a result of checking the O code, the presence or absence of the communication function specified by the 4th bit is set. In this case, the training results are set as "Good," the verification results are "Matched," and the communication function is "Yes," which are set and sent, and notification of permission to receive is sent. ). The transmitting side receives the NSF signal (process 103).
Then, check the training results (process 104)
, If the training result is "good" (Y in process 104), check the results of the other items mentioned above (process 105).
). Then, if each matching result is ``match'' and the communication function is ``available'' (Y in process 105), image information is transmitted (
Process 106).

When the transmission of the image information is completed, a transmission control procedure after a predetermined message is executed (process 107), and the line is disconnected (process 1).
08), the transmission operation ends.

The receiving side receives both pieces of information in response to the sending side (processing 20
9), and then executes the post-message transmission control procedure (process 210), disconnects the line (process 2l1), and ends the receiving operation.

By the way, on the receiving side, if the own device does not have the communication function specified by the sending side (N in process 204), or the received IO code does not match the registered In code. case (N in process 206)
), and furthermore, if the destination phone number is not designated as the reception-permitted destination phone number (N in process 207), the sixth
Set each judgment result to the notification information shown in the figure. Then, as shown in FIG. 5(b), an NSF signal is transmitted to notify the reception rejection (processing 2l2).

Next, the date and time at that point, information on the RTI information and TSI signal received from the other party, and the determination result set in the notification information, etc., are stored in the system memory 9 (
Processing 213). Next, send out the DCN signal (processing 2
14), disconnect the line (proceed to process 211). On the other hand, as described above, when the sending side is notified of rejection of reception using the notification information of the NSF signal (N in process 105), it immediately disconnects the line (process 109). Next, the date and time at that point, the RTI information received from the other party, the CSI signal information, the contents notified in the notification information, etc. are edited into image information for recording (processing 110). Then, the plotter section 4 records and outputs the information as a reception rejection report (processing 11l).

FIG. 7 shows an example of this recording, in which a message 301a indicating that reception has been rejected is recorded at the beginning of the reception rejection report 301. And below that,
Current date 30lb, time 301c, received RT
I information, CS engineering information 301d, and notified judgment result 301c are each recorded.

By the way, if the modem training fails on the receiving side (N in process 203), the notification information is set to the effect that the training has failed, and an NSF signal is transmitted to the transmitting side (process 2l5).

In this case, transmission control is performed according to known procedures. That is, the transmitting side shifts down the transmission speed of the modem and retransmits the modem training signal, and the receiving side performs modem training again in response. As a result, if modem training is successful, it operates in the same way as above, and shifts down to the predetermined transmission speed, and if modem training does not work, the sending side
Send the N signal and stop communication. On the other hand, if the operator on the receiving side wants to know the information of the other party whose incoming call was rejected by the facsimile machine, he requests the output of a reception rejection report by performing a predetermined operation on the operation display section 2 (processing 401). As a result, the facsimile device reads out the date and time of reception rejection, RTI information and TSI signal information of the other party, judgment results, etc. stored in the system memory 9, and edits them into image information (processing 402). Then, the information is recorded and output as a reception rejection report (process 403).
．． FIG. 9 shows an example of this recording, in which the title 501a of the report is recorded at the beginning of the reception rejection report 501. Then, the date 50lb, time 50lb, RTI information of the other party and TSI signal information 501d, and judgment result 501e for each incoming call that was rejected.
are recorded respectively.

As described above, in this embodiment, the called party uses the received ID
If the codes do not match, or if the called party's phone number is not one of those registered as a permitted recipient, the calling party is notified that the call is rejected. When the calling party receives this notification, it outputs a reception rejection report and notifies the operator that the reception has been rejected. You will be able to know if reception is rejected by settings.

In addition, on the called side, upon request by the operator, the information on the recipients who have refused reception is displayed to the operator as a reception rejection report, so that the operator can know the recipients who have refused reception. Become.

This allows you to obtain information as needed by requesting a resend from the recipients listed in the Reception Rejection Report that are judged to need to receive images. It becomes like this. In the above embodiment, the reception rejection on the called side is recorded and outputted as a reception rejection report on the recording paper, but it goes without saying that it may be displayed on the display. In addition, when the calling party's facsimile machine receives a reception rejection notification using an NSF signal from the called party and is instructed to cancel the communication using a DCN signal, the calling party's facsimile machine records and outputs a call rejection report. There is known a facsimile machine that has a retransmission function that repeats retransmission a certain number of times when communication is interrupted by a DCN signal after communication is started.

Therefore, in the case of a facsimile machine equipped with such a re-transmission function, if communication is interrupted due to a transmission error, it will re-transmit as before, but if it receives a reception rejection notification, it will not be able to re-transmit the transmission after that. If the call is not executed, unnecessary call operations can be eliminated.

[Effects of the Invention] As described above, according to the first invention, when the received calling party identification information does not meet the set conditions, the called party
Since the calling party is notified of the reception refusal and the calling party identification information is displayed or recorded, the operator on the called party can know which party has refused reception, and the calling party can When receiving this notification, we display or record that the communication has been canceled due to the setting conditions being violated on the receiving side. You will be able to know that the reception has been refused.
