Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an erroneous dial prevention device, and more particularly, to detecting an erroneous dial when inputting a dial number,
The present invention relates to an erroneous dial prevention device that can prevent an erroneous call.

[0002]

2. Description of the Related Art In a facsimile apparatus, for example, when a dial number of a transmission partner is input by using a ten-key pad on a console panel, an automatic calling device automatically calls the dial number. If the line is not connected to the other device due to this call or if the call cannot be sent,
A typical facsimile machine redials multiple times at predetermined time intervals.

As a result, the operator only needs to operate the dial number of the transmission partner once, and even if the partner device is in use, the operator can call the dial number after use, which greatly improves the operability. However, if you enter the wrong phone number when entering the dialed number, the wrong party will be called many times,
The other party will suffer a great deal of trouble.

In order to solve the above problems, the following techniques have been conventionally proposed.

(1) A predetermined number of past telephone numbers for which facsimile communication has been successful are stored in a memory from the latest call, and telephone numbers for new facsimile communication and telephones stored in the memory are stored. Compare with the number, if it matches, call it, if it does not match, give an alarm,
Request the operator to reconfirm whether the dialed number is wrong or not (JP-A-2-76442, JP-A-2-7).
6443).

(2) At the time of image information transmission, if the dial number is mistakenly input and an attempt is made to transmit it to the general subscriber telephone set, a voice signal for apology is transmitted, and at the transmitting side, The dial number is displayed or printed out to inform the operator on the sending side of the incorrect dial number (Japanese Patent Laid-Open No. 1-233871).

(3) The input dial number is compared with a false dial number registered in advance, and if they match, it is judged to be a false dial number and calling is prohibited. In this way, it is prevented that the number 100 or 109 is erroneously dialed (Japanese Utility Model Laid-Open No. 1-122659).

According to the above-mentioned prior art (1), when the operator of the transmitting side facsimile device makes an erroneous dial input, the erroneous dialing can be prevented with a high probability. According to the conventional technique (2), it is possible to prevent the recurrence of erroneous dialing. Further, according to the prior art (3),
It is possible to prevent wrong dialing to a specific place.

[0009]

However, according to the above-mentioned prior art, although it is possible to inform the operator that there was an erroneous dial, the operator cannot be notified of the correct number, and the reason for the mistake is recognized. There was a problem that I could not. Therefore, there is a problem that the operator may input the same wrong dial number again and fail in the facsimile communication.

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate the above-mentioned problems of the prior art and to provide an erroneous dial prevention device which can inform the operator of the reason when an operator dials incorrectly.

[0011]

According to the invention of claim 1, a telephone number storage unit storing a plurality of dial numbers, a dial number stored in the telephone number storage unit, and a dial input at the time of calling. A comparison unit that compares the numbers with each other to find a matching number and an approximate number, and a calling unit that calls the input dialed number when the comparison unit determines that the numbers match with each other. It is characterized in that it is provided with an output unit for outputting an approximate number when a dialed number to be found is not found.

According to the invention of claim 2, after a call is made, a signal returned from the line is used to determine whether or not there is an erroneous dial, and a telephone number storage section in which a plurality of dial numbers are stored. And a comparing unit for determining an approximate number by comparing the dial number stored in the telephone number storage unit with the dial number input at the time of calling when the incorrect dial determining unit determines that the dialing is incorrect. And an output unit that outputs the approximate number.

[0013]

According to the invention of claim 1, the dial number stored in the telephone number storage unit is compared with the dial number input at the time of calling. When there is no matching number, a similar number is output from the output unit. As a result, before the call is made, it can be determined whether the dialing is wrong or not, the false dialing can be prevented, and it is possible to easily know which digit is wrong.

According to the second aspect of the present invention, it is possible to easily know the mistake of the wrongly dialed number after the call is made.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the drawings.

FIG. 9 is a schematic view of the hardware structure of a facsimile machine to which the present invention is applied. In the figure, reference numeral 1 denotes an operation unit including a numeric keypad and various function keys arranged on a console panel, 2 a reading unit for reading document information to be transmitted, 3 a recording unit for printing out the received document information, 4 Is an image processing unit that performs processing such as encoding or decoding on the transmitted or received document information, 5 is a control unit that controls the entire facsimile communication, 6 is a modulation / demodulation unit,
Reference numeral 7 is a network control unit (NCU). Reference numeral 8 is a telephone number storage unit that stores a speed dial number and all-digit dial numbers in association with each other, and reference numeral 9 is a dial signal generation unit that generates all-digit dial signals for the selected one-touch dial or speed dial. .

Next, one embodiment of the present invention will be described with reference to the functional block diagram of FIG. In the figure, 1a is an input unit, 1b is an output unit, for example, a display unit, and the operation unit 1
It is placed on top. The output unit 1b may be the recording unit 3. Further, 5a is a dial buffer for temporarily storing the dial number input from the input unit 1a, 5b is a comparing unit for comparing the dial numbers to find a matching number and an approximate number, 5c is an approximate number storing unit, and 5d is It is a condition selection unit, and these are functions that the control unit 5 has. The other reference numerals are the same as or equivalent to those in FIG.

Next, the operation of the above embodiment will be described with reference to the flowchart of FIG.

When a dial number is input from the input section 1a, this number is stored in the dial buffer 5a (steps S1 and S2). When the input of the dial number is completed (Yes at step S3), the comparison unit 5b compares the dial number with the data (dial number) stored in the telephone number storage unit 8. If they match as a result of the comparison (Yes in step S4), the process proceeds to step S9 and dialing is performed.

On the other hand, when the comparison result does not match (step S4 is negative), the process proceeds to step S5, and the data stored in the telephone number storage section 8 is temporarily stored in the dial buffer. A determination is made as to whether it is close to the number. As a specific example, among all the dial numbers, data in which one digit number is different by "1" is searched. Then, proceed to step S6,
Record the data. When the comparison with all the data in the telephone number storage unit is completed (Yes in step S7), the process proceeds to step S8 to display the data stored in step S6.

Next, an example of the specific processing of steps S4 to S8 will be described with reference to FIG.

First, one of the registration data in the telephone number storage section is taken out (step S11). Next, 0 is written in, for example, registers N1 and N2 that store the number of unmatched digits (step S12). Also, the check digit number n
1 is written in (step S13).

Next, it is judged whether or not the dial numbers of the check digits match (step S14). That is, the minimum digit number of the input dial number is compared with the minimum digit number of the data extracted in step S11. If they match, the process proceeds to step S18, and 1 is added to the check digit number n. And step S1
When it is determined to be negative in 9, the process returns to step S14 again, and the second digit number is compared. In this way, all digits of the entered dial number are compared with the data retrieved in step S11.

In the above process, if there is a mismatched dial number, the determination in step S14 becomes negative and the process proceeds to step S15 to determine whether or not the number difference is the first difference. If the difference is the largest, step S16
Then, 1 is added to the register N1. on the other hand,
If the difference is not the largest (No in step S15), the process proceeds to step S17, and 1 is added to the register N2.

When the determination in step S19 is affirmative, the process proceeds to step S20 and it is determined whether the values of the registers N1 and N2 are 0 or not. If this determination is affirmative, the process proceeds to step S21, and it is determined that the dial numbers match. On the other hand, if the determination is negative, the process proceeds to step S22, and it is determined whether N1 = 1 and N2 = 0.
In the affirmative, the checked registration data is stored in the memory.

When step S22 is negative or when the processing of step S23 is completed, the process proceeds to step S24, and it is determined whether or not all the registration data in the telephone number storage section have been checked. If this determination is negative, the process returns to step S11 and the same processing as described above is performed.

If the determination in step S24 is affirmative,
The input dial number and the registration data stored in step S23, that is, the registration data with the closest difference in number, are displayed on the display unit 1b. Next, an alarm is activated, and an alarm is issued to the effect that the dial number entered in step S1 of FIG. 2 is incorrect, or that the dial number is not registered in the telephone number storage section.

FIG. 4 shows an example of contents displayed on the display section. As is clear from FIGS. 4 (a) and 4 (b), according to the present embodiment, it is possible to immediately recognize an error in the input dial number.

In the above-mentioned embodiment, the one-digit difference in the dial numbers is displayed on the display section 1b, but this embodiment is not limited to this, and the one-digit difference up to two digits is possible. Alternatively, the first difference of three digits or more may be displayed. Further, when the input dial number is missed by one digit, the registration data of a number close to this may be displayed. For example, the entered dial number is "03-
If it is one digit missing from "446-7890", approximate registration data "03-3446-7890" may also be displayed.

Next, a second embodiment of the present invention will be described with reference to FIG. This embodiment is different from the first embodiment in that the first embodiment judges whether or not the dialed number entered is wrong before making a call, whereas this embodiment makes a judgment after making a call. The point is that when it is determined that the dialing number is incorrect, the telephone number storage unit 8 is searched for a number that is similar to the input dial number.

The operation of this embodiment will be described with reference to FIG. When a dial number is input from the input unit 1a, the input number is temporarily stored in the dial buffer 5a. Subsequently, this number is called by the calling unit 9 and output to the line via the network control unit 7.

When the response from the partner machine is returned via the line, the erroneous dial determination section 5e determines whether or not the dial number is connected to the facsimile machine. If the response signal from the facsimile device is other than the answer back tone and the busy tone indicating busy, the incorrect dial determination unit 5e determines that the dial is incorrect.

When the erroneous dial determination unit 5e determines that the dial is erroneous, the comparison unit 5b is activated. Comparison unit 5b
Compares the dial number stored in the dial buffer 5a with the telephone number registered in the telephone number storage unit 8. Then, as described in the first embodiment, for example, a one-digit or one-digit number is extracted from the telephone numbers registered in the telephone number storage unit 8 and stored in the approximate number storage unit 5c. Remember.

When the comparison with all the telephone numbers registered in the telephone number storage unit 8 is completed, the data stored in the approximate number storage unit 5c is displayed on the display unit 1b. The displayed contents are the same as or equivalent to those shown in FIG.

Therefore, according to this embodiment, the operator can easily know how the dialed number that was called was wrong.

Next, a third embodiment of the present invention will be described with reference to FIG. FIG. 6 shows a block diagram of the essential parts of this embodiment. The difference between this embodiment and the second embodiment is that the registration data to be compared with the comparison unit 5b is stored in the telephone number storage unit 8 as described above.
The point is that not only the data stored in the storage unit 10 but also the data registered in the communication success dial storage unit 10 is referred to.

The data registered in the communication success dial storage unit 10 is stored in the communication success dial storage unit 10 from the dial buffer 5a when the network control unit 7 determines that the communication is successful after the call is made. .

At this time, since the capacity of the communication success dial storage unit 10 is limited, when the amount of data stored in the storage unit 10 becomes full, as shown in FIG. Erase and add new data sequentially.
If the newly added number 11 is already stored in the communication success dial storage unit 10 as shown in FIG. 8, the number 11 is stored in the latest data storage area of the communication success dial storage unit 10. It is preferable to delete the same number in the old area.

According to the present embodiment, since the numbers for which the facsimile communication has been successful in the past are also referred to, the effect of improving the accuracy of the check for erroneous dialing, the correct dialing number and the number close to erroneous dialing are increased. The effect is that you can search from the registration number.

Although the above-mentioned embodiment has been described focusing on the facsimile machine, it is needless to say that it can be applied to a telephone or the like.

[0041]

According to the first aspect of the present invention, it is possible to determine whether or not the input dial number is correct before making a call, so that erroneous dialing can be prevented in advance. Further, when the dialing is an erroneous dial, the approximate correct number is output, so that the incorrect number can be easily recognized.

According to the second aspect of the invention, it is possible to determine which digit of the wrongly dialed number was wrong after the call was made.
You can easily know. And you can call again with the correct number.

According to the third aspect of the present invention, the collation with the dial numbers that have succeeded in the past is also performed, so that the accuracy of the erroneous dial prevention can be further improved.
