Description

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 Recent facsimile machines have a function of selecting whether or not to communicate with the other party according to information such as telephone number data registered in advance when a call is received from the other party in the automatic reception mode. (See, for example, JP-A-62-152254 and JP-A-1-55966).

Specifically, the telephone number of the other party (sending side) to receive the reception is registered in advance in the storage means, and is sent as a TSI signal (transmitting station identification signal) or the like from the sending side when receiving a call. The sender's telephone number is compared with the registered telephone number, and reception is performed only when they match.

[0004]

In a facsimile equipped with such a selective receiving function, unnecessary information unilaterally transmitted from an unknown third party or reception due to mischievous transmission is prevented, and recording paper or the like is prevented. It is possible to prevent the waste of data and to eliminate the problem that the facsimile is monopolized for unnecessary communication and cannot be used when desired.

However, in such a selective reception mode, since reception from only the transmission side registered in advance in the storage means is not accepted, urgent and important transmissions from unregistered third parties are also received. It will not be possible. As a method of avoiding such a situation, there is a method of performing the above registration as much as possible, but in this method, the capacity of the storage means must be large, and the emergency transmission as described above is transmitted from anywhere. There is a problem that it is not possible to register in advance because it is not known.

[0006] In addition, in most cases, the above-mentioned unnecessary transmission actually has a clear transmission destination such as direct mail, and it suffices if only this transmission is not received.

[0007]

The present invention has been made in view of the above points, and a first feature thereof is a dial memory for storing telephone number data and a transmitting side facsimile transmitted in a receiving mode. Means for detecting the telephone number data of the device, means for determining whether or not the data detected by the means matches the telephone number data stored in the dial memory, and the means for detecting the data by the detecting means. Means for controlling not to perform reception when it is determined that the received data matches the data in the dial memory.

The second feature is that the first dial memory for storing the telephone number data of the transmitting side facsimile machine which permits reception in the receiving mode and the telephone number data of the transmitting side facsimile machine which does not permit reception in the receiving mode. , A means for detecting the telephone number data of the facsimile apparatus on the transmitting side transmitted in the reception mode, a means for instructing switching between selective reception and non-reception of selection, and selection by the instructing means. When the reception is instructed, the reception is performed only when it is determined that the data detected by the detection means and the telephone number in the first dial memory match, and when the selection non-reception is instructed by the instruction means. The data detected by the detection means and the second data
It is provided with means for controlling not to receive when it is determined that the data matches the telephone number data in the dial memory.

A third feature is that the coincidence between the data detected by the detecting means and the data in the dial memory is determined only by the last 4 digits.

[0010]

According to the first feature, it is possible to selectively prevent the reception of unnecessary information that is frequently transmitted.

According to the second feature, it is possible to selectively switch between reception and non-reception from a specific destination, if necessary.

According to the third feature, a reliable determination can be made regardless of the registration form of the telephone number of the other party.

The reading unit (3) is composed of an original feeding mechanism, an image sensor, and the like. A recording unit (4) drives a recording head such as a thermal head to perform printing under the control of the control circuit (1) based on the received signal.

Reference numeral (5) is a data memory for storing the original data read by the reading unit (3) or signal-processed data, and (6) is a dial memory, which is a receivable memory area (61). ) And reception prohibited memory area (62)
Consists of. The receivable memory area (61) can store, for example, telephone number data for 100 stations, and
As described in JP-A-1-55966, this data can be used as destination data at the time of transmission in association with the speed dial number and the one-touch dial key. The reception prohibited memory area (62) has, for example, 5
It is configured to be able to store telephone number data for stations.
The writing and reading of data to and from the memories (5) and (6) are controlled by the control circuit (1).

Reference numeral (7) is a keyboard, which includes a transmission key, a reception key, a ten-key, a one-touch key, and a function key for switching various modes.

Reference numeral (8) is a display for displaying the data inputted from the keyboard (7) or the data processed by the control circuit (1), which is constituted by a liquid crystal display or the like. A modem circuit (9) modulates a signal to be sent to the telephone line (L) and demodulates a signal from the telephone line (L), and is connected to the line switching circuit (10). The line switching circuit is composed of a relay circuit for switching and connecting the modem circuit (9) and the telephone set (11) to the telephone line (L), and switching control is performed by the control circuit (1). The line switching circuit (10) has a built-in incoming call detection circuit that generates an incoming call detection signal by detecting an incoming call signal. An automatic dial device (12) generates a dial signal based on telephone number data input by using a ten-key pad, a one-touch key or the like of the keyboard (7), and a telephone line (L) via a line switching circuit (10). ) Is output.

Next, the operation of the present invention having such a configuration will be described with reference to the flowchart shown in FIG. First, prior to the use of the facsimile device, the telephone number data of the other party who is permitted to receive the data is received at the dial memory (6).
In the receivable memory area (61), while the reception prohibiting memory area (62) stores the telephone number data of the other party (sending side) whose reception is prohibited during reception. These data are input from the keyboard (7). The reception mode is set using the keyboard (7) and stored in the data memory (5). Specifically, in this reception mode, reception is performed only when the telephone number of the transmitting side, which is transmitted as a TSI signal from the transmitting side during reception, matches the telephone number stored in the receivable memory area (61). The selective reception mode to be performed, the selective non-reception mode in which reception is prohibited when the telephone number of the transmission side sent as a TSI signal matches the telephone number stored in the reception prohibition memory area (62), and all It has three modes of receiving all receptions, one of which is selected on the keyboard (7) and stored in the data memory (5).

When the automatic incoming call mode is entered in such a state, the control circuit (1) first determines whether or not there is an incoming call in step S1. This judgment is made by the line switching circuit (1
0) based on the output from the incoming call detection circuit built in.

When an incoming call is detected in step S1, the control circuit (1) connects the telephone line (L) to the modem circuit (9) in step S2 and then proceeds to step S3 to send a response signal (CED) as shown in FIG. Signal) to the telephone line (L) via the modem circuit (9).

In the following S4 step, it is determined which mode is set based on the data in the reception mode stored in the data memory (5). If it is determined in this determination that the all reception mode is set, the process proceeds to step S5. In step S5, known reception processing is performed. That is, the facsimile signal transmitted through the telephone line (L) is demodulated by the modem circuit (9), the signal is decoded and then output by the recording unit (4), or the data memory (5). Store inside. When the completion of this reception process is detected in step S6, the line is disconnected in step S7, and the process is returned to step S1.

On the other hand, if it is determined in step S4 that the selective reception mode is set, the process proceeds to step S8. In step S8, the telephone number data included in the TSI signal sent from the transmitting side is detected as shown in FIG. In the following S9 step, the telephone number data detected in the above S8 step is compared with the telephone number data stored in advance in the receivable memory area (61) of the dial memory (6).
Proceed to step 5, and perform normal reception processing. When it is determined that there is no match, the process proceeds to step S10, and a line disconnection signal (DCN signal) is sent to the transmitting side. After that, the line is disconnected in step S7.

The matching determination in step S9 is performed by determining all digits of the detected telephone number data and the receivable memory area (6
It can be accurately performed by comparing all the digits of each data stored in 1).

When making a call in Japan, it is sufficient to dial the area code and a 4-digit number within the same area code, and when making a call to a different area code area, the area code, area code and 4-digit number. It is necessary to dial the number of the area code. Therefore, if the receiving side has registered the telephone number including the area code, but the sending side sends the telephone number that does not include the area code, or In the opposite case, the mutual telephone numbers do not match, so reception cannot be performed. Further, even if both the transmitting and receiving sides are registered in the form excluding the area code, even if one inserts a hyphen between the area code and the four-digit number and the other inserts a space, the mismatch will occur. In order to solve such a problem, it is possible to make a coincidence determination using only the last four digits of the telephone number.

Returning to step S4, if it is determined in this step that the selection has not been received, the process proceeds to step S11. In step S11, T is the same as in step S8.
The telephone number data included in the SI signal is detected, and then S1
In two steps, the telephone number data stored in advance in the reception prohibited memory area (62) of the dial memory (6) is compared. In this comparison, if it is determined that there is no match, the process proceeds to step S5 and normal reception process is performed. If there is a match, the process proceeds to step S13, a line disconnection signal (DCN signal) is sent to the transmitting side, and then the line is disconnected in step S7.

[0025]

As described above, according to the present invention, it is possible to selectively prevent reception such as direct mail that the user does not want, and thus it is possible to prevent waste of recording paper accompanying reception of unnecessary information.

Further, by selectively switching between such selective non-reception and conventionally known selective reception, for example, when there is an emergency transmission from a specific person, only the transmission from this specific person is prioritized. Since it can be arbitrarily received, and it is possible to arbitrarily reject only the reception from a specific person,
It is easy to use and the running cost can be reduced.

Further, since the sender is specified by the last four digits of the telephone number data sent from the sender, it is not necessary to provide a special regulation for registering the telephone data.
