DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine.

[0002]

2. Description of the Related Art In some cases, a facsimile apparatus is used for unnecessary communication due to direct mail or the like using the facsimile apparatus. This may hinder the reception of urgent communications from other callers, or may cause unnecessary consumption of recording paper by printing unnecessary contents on recording paper. There was a problem.

For this reason, the conventional apparatus recognizes the fax number of the caller from the TSI signal transmitted from the caller, and recognizes the fax number and the fax number registered in advance as the caller whose refusal is to be rejected. Are sequentially compared, and if there is a match, the facsimile communication with the transmitting side is interrupted. That is, when the image data from the transmitting side is printed on the recording paper, usually, together with the image data, a facsimile number or the like is printed on the upper end corner of the recording paper as transmission source information. Therefore, based on the fax number printed on the recording paper, it is possible to register the fax number of the calling party whose reception is to be rejected.

[0004]

However, the fax number of the caller, which is printed on the recording paper together with the image data from the caller, lacks credibility. That is, the printed fax number is simply image data that is arbitrarily set and input on the calling side, and is not identification data unique to the calling side. Therefore, the calling party can register a fake fax number instead of the real fax number, so it is certain that the printed fax number is the sender's real fax number. I couldn't. Also, if the fax number has not been entered on the calling side, the fax number will not be printed on the recording paper.
It becomes impossible to reject communication from the caller. or,
Between the registered fax number and the fax number included in the TSI signal, for example, “123456”, “123”
Even if there is a space in the fax number, such as "456" or "12-3456", or if there is a hyphen, it will not be possible to reject the communication from the calling party. there were.

As described above, even if the fax number to be printed on the recording paper is registered together with the image data from the caller, it is impossible to reliably reject the communication from the caller corresponding to the registered fax number. could not.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a facsimile apparatus capable of reliably disabling unnecessary facsimile communication from a caller. .

[0007]

In order to achieve the above object, according to the present invention, there is provided a storage means for temporarily storing a TSI signal transmitted from a transmitting side at the time of facsimile reception, and a storage means for temporarily storing the TSI signal. Registering means for setting and registering a TSI signal; and a positive response to communication from an originating side having the registered TSI signal even if an error is detected.
After performing the spoofing reception operation set to
Finally, a fake receiving means for invalidating facsimile communication with the transmitting side is provided.

[0008]

Therefore, according to the present invention, at the time of facsimile reception, the TSI signal (transmitting terminal identification signal) transmitted from the transmitting side is temporarily stored. The TSI signal is provided with a Facsimile Information Field (FIF), and the FIF contains identification data unique to the apparatus such as a fax number. If the user does not want to perform communication with the transmitting side that has transmitted the image data after seeing the received image data printed on the recording paper, the registration unit registers the temporarily stored TSI signal. I do. Then, even if an error is detected in the communication from the transmitting side having the registered TSI signal, the communication is false.
Receiving operation is performed on the device, and the disguised receiving operation ends.
Facsimile communication between the sender and the sender is disabled.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, C PU (central processing unit) 1, ROM based on (read only memory) 2 in the stored program to control the operation of the entire apparatus. A RAM (random access memory) 3 as a storage unit temporarily stores various information such as transmission / reception image data and data of a TSI signal (transmission terminal identification signal) described later transmitted from the transmission side.

The NCU 4 controls connection with a telephone line.
The modem 5 modulates and demodulates transmission and reception data. Reading unit 6
Is for reading an image on a document. Recorder 7
Is for printing on recording paper based on the received image data and the like. The key input unit 8 includes a dial key (not shown) for inputting a fax number or the like, a registration key 9 for setting and registering the data of the TSI signal temporarily stored in the RAM 3, and a fake reception described later. A setting key 11 for setting and canceling the mode is provided. The display unit 10 is for displaying various information.

The TSI signal has an FIF (Facsimile In)
The FIF contains unique identification data of the apparatus such as a fax number. That is, the identification data in the TSI signal is not set and input by the user and is not printed out together with the transmission image data on the receiving side, but the unique identification data of the apparatus such as the fax number is accurately transmitted to the receiving side. It is for doing. Then, the TSI signal is transmitted to the receiving side at the time of facsimile transmission, and the receiving side can accurately specify the transmitting side based on the identification data in the received TSI signal.

In this embodiment, the CPU 1 and the RAM
3, and a registration key 9 constitute a registration means. That is, at the time of facsimile reception, the data of the TSI signal transmitted from the transmitting side is temporarily stored in the RAM 3. When the registration key 9 is operated after the facsimile reception operation is completed, the CPU 1
The data of the SI signal is set and registered in the RAM 3.

In this embodiment, the CPU 1 and a setting key are used.
-11 constitutes a forgery receiving means. That is, C
When detecting an incoming call from the transmitting side having the TSI signal registered and set, the PU1 interrupts the facsimile receiving operation and disconnects the facsimile communication with the transmitting side, or performs fake reception. May be. Here, the fake reception means that the image data from the transmission side is temporarily stored in the RAM 3 without interrupting the facsimile reception operation.
And deleting the stored image data after the end of the receiving operation. And the key input unit 8
By operating the setting key 11, the setting and release of the camouflage reception mode are performed, and the camouflage reception mode is set.
In this case, a spoofed reception described later is performed
Communication between the side is invalidated, when the impersonation reception mode is released, the operation of the line disconnection by interrupting the facsimile receiving operation is performed.

Next, the operation of the facsimile apparatus configured as described above will be described. When receiving the facsimile apparatus, the operation shown in the flowchart of FIG. That is, when an incoming call from the calling side is detected, an NSF signal (non-standard function identification signal), a CSI signal (called terminal identification signal), and a DIS signal (digital identification signal) are sent to the calling side ( Steps S1 and S2). Then, the NSS from the calling side
Signal (non-standard function setting signal), the TSI signal, and D
A CS signal (digital command signal) is transmitted, and those signals are received (step S3).

The data of the received TSI signal is temporarily stored in the RAM 3, and the data of the TSI signal temporarily stored in the data of the TSI signal already set and registered in the RAM 3 are stored in the RAM 3. It is determined whether there is a match (steps S4 to S5). If there is no match, it is determined that reception is permitted, and the normal facsimile reception operation, that is, the recording unit 7 is activated,
The image data transmitted from the transmitting side is printed on the recording paper (step S6). In the receiving operation, the received image data may be temporarily stored in the RAM 3 and a predetermined key operation may be performed after the receiving operation to print out the stored image data.

The TS registered and set in the RAM 3
In the data of the I signal, the temporarily stored TSI
If there is a signal that matches the signal, it is determined that the reception has been rejected, and it is determined whether or not the camouflage reception mode has been set (steps S5 and S7). If there is no setting of the spoofing reception mode, the facsimile reception operation is interrupted and the line is disconnected, and then the T 3 temporarily stored in the RAM 3 is stored.
The data of the SI signal is erased (steps S8 to S8).
9). That is, the data of this TSI signal has already been set and registered in the RAM 3 as the data of the transmitting side that refuses the communication, and it is not necessary to store it. Therefore, the data is deleted when the facsimile receiving operation is interrupted. ing.

If it is determined in step S7 that the camouflage reception mode is set, camouflage reception is started.
That is, in training, when setting the transfer rate with the caller, the highest transfer rate is selected, and even if an error can occur at that transfer rate, communication is possible at the highest transfer rate. Tell the caller. Then, in the subsequent image data reception, even if an error is detected, a setting is made so that a positive response is made (step S10), and the process proceeds to the image data reception operation. And
The received image data is temporarily stored in the RAM 3,
When the receiving operation is completed and the line is disconnected, the stored image data is deleted (steps S11 to S13). Then, the process proceeds to step S9.

After the normal facsimile reception operation is completed in step S6, the user does not want to see the received image data printed on the recording paper and thereafter perform communication with the transmitting side that has transmitted the image data. In this case, the registration key 9 is operated before the next incoming call. Then, RAM3
The data of the TSI signal temporarily stored therein is set and registered. Therefore, even if an incoming call from the transmitting side having the TSI signal is detected, facsimile communication with the transmitting side is interrupted or received in a forged manner, and image data from the transmitting side is recorded on the recording paper. Is not printed out.

If the user wants to see the image data printed on the recording paper and continue to communicate with the transmitting side that has transmitted the image data, the registration key 9 is used until the next incoming call is received.
Do not operate. Then, at the same time that the next incoming call is detected, the data of the TSI signal temporarily stored in the RAM 3 is deleted.

As described above, in the facsimile apparatus of this embodiment, the registration key 9 is operated for the transmitting side that has transmitted unnecessary image data, and the transmitting side TS is transmitted.
What is necessary is just to register the data of the I signal in the RAM 3. Since the TSI signal contains identification data unique to the transmission side, the transmission source information is very reliable unlike the transmission source information printed on the recording paper together with the image data. That is, if the data of the received TSI signal is registered, the TSI signal transmitted from the same transmitting side thereafter is naturally the same as the registered TSI signal. Therefore, register the TSI signal of the caller you want to deny communication Then
If both are set to the spoofed reception mode, even if an incoming call is detected from the calling side, facsimile communication with the calling side will be performed even if an error is detected.
It can be terminated by communication, and finally be surely invalidated.

Therefore, it is possible to avoid unnecessary printing of the recording paper and unnecessary consumption of the recording paper.
If the fake reception mode is not set, facsimile communication with the caller is immediately interrupted, so the facsimile machine is used for unnecessary communication and urgent communication from other callers It does not hinder reception.

Further, even in the spoofed reception mode, since the communication time is shortened by using the highest transfer rate as the transfer rate, it is difficult to receive the urgent communication from another transmission side. Almost no. That is, in the disguised reception mode, the image data stored in the RAM 3 is deleted without being printed, so that there is no inconvenience even if an error is included. Therefore, even if an error occurs, by making a positive response, communication can be performed using the highest transfer rate.

Further, when the forged reception is performed, the communication procedure is executed to the end without interruption, so that the transmitting side determines that the transmission has ended normally, and the transmitting side determines that the communication procedure has abnormally ended. Therefore, there is no fear that the call will be sent again.

The present invention is not limited to the above embodiment, but can be embodied, for example, in the following modes. (1) When fake reception is performed or facsimile communication with the transmitting side is interrupted, the contents relating to them, for example, identification data in the TSI signal of the transmitting side, communication time, and the like are transmitted to R.
The contents are stored in a predetermined storage area in the AM3, and the stored contents are printed out as a journal report by a predetermined key operation. With such a configuration, it is possible to easily confirm from what partner and when the unnecessary communication was received. (2) A configuration in which the camouflage receiving mode is set only in a preset time zone. In the case of such a configuration, a setting is made such that the camouflage reception mode is set only in a time zone in which unnecessary direct mail is large, for example, at night, and a setting is made such that the camouflage reception is not performed during the working hours in the daytime. Selection becomes possible.
