Abstract

PROBLEM TO BE SOLVED: To provide facsimile equipment, with which the lack of ability for receiving data can be reported to the party of a transmitting source. SOLUTION: When caller number information is received (S501; Y), in the facsimile equipment, a refusal decision is performed for deciding whether that information shows a number on a refusal number list or not (S502). When it is decided that the number is not on the refusal number list (S502; N), ordinary facsimile receiving is executed (S506). When it is decided that the number is on the refusal number list (S502; Y), incoming call refusing operation is started (S505). When the caller number information is not received (S501; N), it is confirmed whether number/TSI non-report selection shows refusal or not (S503). When that selection is refusal (S503; Y), incoming refusing operation is started (S505). When the selection is not refusal (S503; N), ordinary facsimile receiving is executed (S506).

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile apparatus capable of rejecting an incoming call according to a sender by a sender number notification service.

[0002]

2. Description of the Related Art In recent years, with the development of communication technology, telephones,
In a communication device such as a facsimile machine, the calling line number of the called party (calling side), that is, the telephone number can be notified to the called party (received party). Can be specified.
In addition, by registering a phone number that can be received in advance in a telephone or a facsimile device, a phone number other than the registered number or a non-received call that does not notify the number (for example,
You can also make settings such as rejecting incoming calls such as payphones and anonymous calls. Regarding such an incoming call refusal, Japanese Patent Laid-Open No. 2000-49934 discloses that by registering a partner line number that accepts an incoming call in the incoming call declaration mode and an incoming call allowable period for the line number,
There is described a communication device with an incoming call rejection function that can allow incoming calls to a partner line number within a limited incoming call period.

[0003]

However, in the communication device with an incoming call rejection function described in Japanese Patent Laid-Open No. 2000-49934, when the destination line number registered as not accepting the incoming call is the destination. , Even though the incoming call is rejected at the destination, it remains ringing at the destination,
If the call is not stopped at the call destination (calling side), there will be a problem in that the call cannot be received from others at the call destination. In addition, even if a facsimile machine capable of rejecting an incoming call from a specific destination is rejected by using a destination identification signal such as caller ID notification, the incoming call is rejected at the destination as well. In addition, it is possible that the transmission destination (calling side) cannot transmit the data because the facsimile device of the transmission destination does not end normally, and redialing is repeated many times. As described above, it is conceivable that the destination repeats the transmission operation for a long time after the call is received in the facsimile apparatus, which causes a problem that another communication cannot be performed during the period. In addition, when the called party is a facsimile machine and the calling party you want to reject is a telephone or the number is a call rejection number that is already registered in the fax machine, you can reject the call after receiving the call. There is the annoyance that the line will be held only for the time until the line is disconnected.

Therefore, a first object of the present invention is to provide a facsimile apparatus capable of notifying a destination, which is a transmission source, that an incoming call is rejected, that is, that the destination has no ability to receive data. It is to be. Second of the present invention
It is an object of the present invention to provide a facsimile apparatus capable of preventing the unauthorized use of the line for a long time by notifying the destination that is the sender that the incoming call is rejected. A third object of the present invention is to notify the other party that he / she does not have the data receiving capability, depending on whether or not the other party, which is the transmission source, corresponds to the already registered party who wants to reject the incoming call. It is an object of the present invention to provide a facsimile device capable of changing the setting of the time.

[0005]

According to a first aspect of the present invention, in a facsimile apparatus capable of rejecting facsimile communication according to a telephone number of a called party, a communication means for transmitting / receiving data to / from the called party is provided. An output means for outputting the data received by the communication means on a predetermined sheet, a number information acquisition means for acquiring the telephone number of the called party as outgoing number information, and a telephone number of the called party for whom the incoming call is rejected Storing means for storing as a refusal number, judging means for judging whether or not the calling number information acquired by the number information acquiring means corresponds to the refusal number stored in the storing means, and the judging means. Determines that the calling number information acquired by the number information acquisition means corresponds to the rejection number stored in the storage means, the Notification means for notifying that the communication is rejected, and the communication means receives data from the other party after notifying the other party by the notifying means that the facsimile reception is rejected. ,
By the output means not outputting the data,
The first object is achieved.

According to a second aspect of the present invention, in the first aspect of the invention, a set time for the communication means to set a time limit for receiving data with the other party, and the communication means for data from the other party. Measuring means for measuring the time during which the data is being received, and when the measurement by the measuring means exceeds the time limit set by the setting means, the communication means receives data from the other party. The second objective is achieved by hanging up. According to a third aspect of the present invention, in the second aspect of the present invention, the communication means further comprises time changing means for changing the time until the communication means hangs up, and the other party stores the determination means in the storage means. When it is determined that the communication number corresponds to the rejected number, the time changing unit achieves the third object by shortening the time until the communication unit hangs up than the time limit.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to FIGS. Rejection of an incoming call in the facsimile apparatus of the present embodiment means that even if the data transmitted from the partner machine of which the number is notified is received, it is not printed out on the paper. FIG. 1 is a block diagram showing a schematic configuration of a facsimile apparatus according to this embodiment. As shown in FIG. 1, as an example, the facsimile apparatus according to the present embodiment reads a document, a reading unit 1, a recording unit 2, an encoding / decoding unit 3, a system control unit 4, a system memory 5, an image information memory 6, The operation display unit 7 and the communication control unit 8 are provided. Further, the communication control unit 8 is connected to the modem 9 and the SW (switch) unit 10.

In the facsimile apparatus of this embodiment, the following control is performed. The recording unit 2 records data such as received image information and reports, and the encoding / decoding unit 3 encodes / decodes this image information. The system memory 5 is a non-volatile memory that stores setting data, program data, etc. used by the system control unit 4. The system control unit 4 controls the entire system according to the setting data and program data in the system memory 5. The image information memory 6 stores and saves image information as needed. The operation display unit 7 includes keys, LEDs, and L
A CD or the like is provided and is a part that prompts the user to perform an input operation. The communication control unit 8 controls transmission with another communication device (for example, a telephone, a facsimile device, etc.) connected to the facsimile device of this embodiment. The modem 9 modulates / demodulates an analog signal between the line and the communication control unit 8 in order to communicate with another communication device.
The SW unit 10 has a physical I / F (interface) with a line, and switches the line connection with another communication device such as a telephone side or a facsimile side.

Now, a general procedure of calling party number notification will be described with reference to FIG. FIG. 2 is a diagram showing a procedure of calling number notification performed between the subscriber exchange and the receiver. First, when a polarity reversal and an ID reception terminal activation signal indicating that communication is desired to be performed from a subscriber exchange to a communication terminal device (corresponding to a facsimile device in this embodiment), the communication terminal device side Then, a primary response is made to the subscriber exchange as a response that it has been received. The subscriber exchange that has received this primary response transmits the sender number information. When the communication terminal device that has received the caller number information transmits a reception completion notification, the subscriber exchange sends a call signal. When a secondary response is returned from the communication terminal device to this call signal, polarity reversal is performed,
G3 communication starts. With such a procedure, the communication terminal device, which is a receiver, can recognize the telephone number of the transmission source (calling side).

Next, in the G3 communication, the facsimile apparatus of this embodiment, which is a receiver, changes the telephone number on the transmitter side to TSI (Transmitting Subscribe).
erIdentification: identification of the transmission terminal) will be described. FIG. 3 is a diagram showing a procedure for recognizing a telephone number on the transmitter side. First,
The telephone number recognition procedure will be described with reference to FIG. Upon receiving the CNG (calling tone), the receiver (facsimile device according to the present embodiment) notifies the transmitter that it has no receiving capability when the telephone number of the transmitter is the call rejection target. , T1 timer that counts the time T1 until hangup is started, and CED (Called station identification), NSF (Nonstandard function), CSI (Called terminal identification), DIS (Digital identification signal) are sent to the transmitter. Send. Then, the receiver sends TS as a response from the transmitter side.
I, DCS (digital command signal), TCF (training check) are received, and measurement of the maximum reception time is started. Here, the DIS frame transmitted from the receiver to the transmitter will be described. The DIS frame is used by the receiver to notify the transmitter of the capabilities of the receiver itself. As an example, FIG. 3B has FLG (flag sequence), AF (address field), CF (control field), FCF (facsimile control field), FIF (facsimile information field), and FCS (frame check sequence). In this way, the DIS is divided into several fields in the frame.

Next, the receiver side transmits a CFR (reception preparation confirmation) to the transmitter while determining whether or not the transmitter is an incoming call rejection target based on the received TSI. Here, when it is determined that the transmitter is a call rejection target, the receiver side discards the PIX transmitted,
That is, the received data is not printed out by the facsimile device. The receiver is the EOP from the transmitter
MCF (message confirmation) upon receiving (end of procedure)
To wait for DCN (disconnect command) from the transmitter. When receiving the DCN from the transmitter, both the receiver and the transmitter hang up and the communication is disconnected. Since the TSI, which is a telephone number, is not always notified, whether or not to reject when the number is not notified is set in advance in the system memory 5 by the operation display unit 7 according to the user. May be allowed.

FIG. 4 is a diagram showing a refusal number list. As shown in FIG. 4, when the number notification is received, the user can set a reject telephone number list on the operation display unit 7 for determining whether or not to reject the number. . In addition, set the T1 timer that counts the time T1 until a hang-up, the maximum communication time, and the selection when no number / TSI is not notified, informing you that you do not have the receiving ability when the phone number is rejected. You can In this embodiment, as an example, in the case of rejecting an incoming call, the T1 timer is set to 15 seconds (seconds) and the maximum communication time is set to 120 seconds.

Next, the process of determining whether or not the telephone number is the call rejection target in the procedure of FIG. 3A is shown in FIG.
This will be described with reference to the flowchart of FIG. FIG. 5 is a flowchart showing a procedure for determining a sender number. When the receiver (facsimile device of this embodiment) receives the polarity inversion and ID reception terminal activation signal from the subscriber exchange, it goes off-hook (becomes a primary response) and receives the caller number information. When the receiver receives the caller number information (step 501; Y), a rejection decision is made as to whether or not the received caller number information is a number in the reject number list as shown in FIG. 4 (step 502). ). When it is determined that the number is not in the rejection number list (step 502; N), normal facsimile reception is performed. On the other hand, when it is determined that the number is in the rejection number list (step 502; Y), the operation proceeds to the call rejection operation (step 505).

When the receiver does not receive the calling party number information (step 501; N), the receiver determines the number / TSI.
It is confirmed whether or not the non-notification selection (see FIG. 4) is rejected (step 503). Where number / TSI
If the selection when not notified is rejected (step 50)
3; Y), and shifts to a call rejection operation (step 50)
5). On the other hand, if the number / TSI non-notification selection is not rejected (step 503; N), normal facsimile reception is performed (step 506).

FIG. 6 is a flowchart showing the operation processing procedure of the facsimile apparatus according to this embodiment. Facsimile equipment, polarity reversal from the subscriber exchange, ID
When the receiving terminal activation signal is received, it goes off-hook (becomes a primary response) and receives the caller number information (step 60).
1). When the receiver receives the caller number information (step 601), it judges whether or not the received caller number information is a number in the reject number list as shown in FIG. 4 (step 602). When it is determined that the number is not in the rejection number list (step 602;
N), since the facsimile reception is possible, the T1 timer is set to 35 ± 5 seconds (step 603).

On the other hand, when it is determined that the number is in the reject number list (step 602; Y), the facsimile machine starts T1 when sending CED after the secondary response.
System memory with preset timer 5
It is set to a value according to [T1 timer at the time of refusal] (step 604). Since the NSF is a non-standard frame unique to the manufacturer of the facsimile machine, the manufacturer does not have a receiving function and defines it in the frame data. Also, since DIS is a standard frame, FIG.
As shown in (b), ITU-T (Internati)

Recommendation T. Nardardization Secret: International Telecommunication Union Telecommunication Standardization Sector) According to the definition defined in No. 30, by setting the operation of the bit 10 of the FIF: receiver-facsimile device to "0", the other party is notified of no reception function. Then, set the T1 timer to NSF.
/ DIS is retransmitted at intervals of 3 seconds, the time is subtracted until a DCS response is received from the other party, and if the T1 timer becomes 0 before the DCS response is transmitted, it hangs up.

Then, the phase A starts, and as the call setting, the capability is declared to the transmitting side by NSF / DIS, but if the rejection is judged, it is declared that there is no receiving capability (step 605). Next, at the start of phase B, as a pre-message procedure, the capability of the facsimile machine is identified, the selected condition is instructed, the acceptable condition is confirmed (step 606), and whether the rejection has already been judged in step 602. Please check (Step 6)
07). Reconfirmation of the refusal judgment here is step 605.
This is performed when the TSI / DCS for NSF / DIS performed in step 1 is transmitted from the other party, and the refusal determination is performed again using TSI. If the rejection judgment has already been made at the time of the judgment based on the sender number (step 602; Y),
The “rejection” is left as it is (step 607; Y). In step 602, the refusal judgment has not already been made (step 6
07; N), if the TSI is not the rejection pattern (step 608; N), it means that the recipient is a receivable party, and the normal facsimile reception operation is performed (step 621), and the communication processing is ended.

After the re-judgment in step 607, if the refusal judgment has already been made (step 607; Y), or if the TSI is a refusal pattern (step 60).
8; Y), measurement of the reception time is started to determine the maximum reception time (step 609). Then, as phase C starts, the in-message procedure and the message transmission receiving procedure are advanced (step 610). When the modem receives the PIX (step 611), the image information which is the data read from the modem is discarded without being decoded (paper output) (step 612). When the modem does not receive the PIX (step 611; N), the image information which is the data read from the modem is not discarded. Then, when the measured reception time at the time of refusal reaches the maximum time (step 613;
Y), hang up (step 622), and terminate the communication process.

On the other hand, when the measured reception time at the time of refusal has not reached the maximum time (step 613; N), it is judged whether the reception of the image information is completed (step 61).
4). If the image information has not been received (step 6)
14; N), the processes of steps 611 to 614 are repeated. If the image information has been received (step 61)
4; Y), a message end signal as the start of phase D,
Information concerning a confirmation signal, a multi-page signal, a facsimile procedure end signal, etc. is transmitted to the other party (step 61).
5). Here, when the information indicating that there is a next page is transmitted from the other party (step 616; Y) and the facsimile reception mode is changed (step 618; Y), the process returns to phase B and the communication process from step 606 is performed again. (Step 620). On the other hand, when the information indicating that there is a next page is transmitted from the other party (step 616; Y) and the mode of facsimile reception is not changed (step 61).
8; N), the process returns to phase C, and the communication process from step 610 is performed again (step 619). If there is no next page (step 616; N), the call is released in phase E, the connection with the partner is cut off (step 617), and the communication processing is ended.

As described above, in the facsimile apparatus of the present embodiment, it is possible to prevent reception from a specific destination by using the destination identification signal such as notification of the sender number. For the destination (source) that you do not want to receive, the transmission capability is declared as the capability of the fax machine itself to indicate that there is no receiving function, so you can encourage the destination to suspend communication and not redial. it can. Further, in the facsimile apparatus of the present embodiment, if the procedure is advanced despite the fact that the other party is notified that the receiving function is not available, the normal reception / transmission procedure is advanced, but recording output is not performed. Therefore, it is possible to make it appear to the other party that the communication has been normally performed, and it is possible to prevent the other party from redialing or calling for a long time. Further, in the facsimile apparatus of the present embodiment, after receiving a call from the other party that is rejected, although the normal receiving procedure is advanced, if communication continues for a certain time or more, communication with the other party hangs up. It is possible to avoid using unfair lines for a long time. Further, in the facsimile apparatus of the present embodiment, when the other party (calling side) is the person who wants to reject, the time T1 until hang-up can be set short, so that the calling party who wants to reject is the telephone number. The line can be released quickly in cases such as when.

[0021]

According to the first aspect of the invention, when the communication means receives the data from the destination after the notification means notifies the destination that the facsimile reception is rejected, the output means causes the data to be transmitted. Since it does not output, it is possible to interrupt the communication by notifying the other party that there is no reception capability, and even when the communication is continued, it is possible to redial and long time by making it appear to the other party as normal communication. Can be called.

According to the second aspect of the present invention, when the measurement by the measuring means exceeds the time limit set by the setting means, the communication means hangs up the data reception from the other party, so that it is unreasonable for a long time. You can avoid using the line.

In the invention according to claim 3, when the other party determines that the judging means corresponds to the refusal number stored in the storing means, the time changing means limits the time until the communication means hangs up. Since it is shorter than the above, the line can be opened quickly even when the other party (calling side) who wants to reject is a telephone.
