Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a data communication device that performs data communication via a communication line.

[Conventional technology]

As one type of data communication device, a facsimile device connected to a telephone line has been widely known.

Many currently known facsimile machines have a function that allows the user abbreviation and telephone number of the sending side (own station) to be registered in advance, and sends the sender information to the other party before sending the image data. is provided.

[Problems to be Solved by the Invention] However, with these facsimile devices, it has not been possible to store the user abbreviation of the communication partner together with the telephone number of the other party. Therefore, even if the user abbreviation of the dialed party had changed from the previous one, it could not be recognized, and the image information was sent unconditionally.

For example, the phone number of the communication partner (Company A) is 123-45.
Suppose it was 67. However, assume that Company A's telephone number has since changed to 234-5878, and that Company B now uses the telephone number 123-4567 that Company A had been using up until now. In such a case, the sending side dials the phone number 123-4567 and thinks it is sending image information to company A, but the big drawback is that this image information is actually sent to company B. was there.

Such problems also occur when you move, etc.
With the spread of facsimile machines, leakage of image information has become a serious problem.

SUMMARY OF THE INVENTION Therefore, in view of the above-mentioned points, an object of the present invention is to provide an image communication device configured to start sending and receiving image information after confirming the user abbreviation of the communication partner.

Send image information only to Furthermore, if the user abbreviations do not match, the operator is instructed to that effect.

FIG. 3 is a flow chart showing the control procedure to be executed by the control circuit 26 shown in FIG. In this figure, step S4
0 represents the start of control.

In step S42, it is determined whether a mode for registering a telephone number and user abbreviation corresponding to a one-touch key has been selected (that is, whether or not the "FJ" and "1" keys have been pressed). As a result, if the mode for registering the telephone number and user abbreviation corresponding to the one-touch key is selected (that is, if the "F" or "1" keys are pressed), the process advances to step S44. Also,
If the mode for registering phone numbers and user abbreviations corresponding to one-touch keys is not selected (i.e.
If the "F" or "1" keys are not pressed), the process advances to step S44.

In step S44, a telephone number and user abbreviation are registered in response to pressing the one-touch key. Specifically, after outputting (alphabet key)*(telephone number)*(user abbreviation) manually inputted from the operation unit 20 to the signal line 24a, a write pulse is generated to the signal line 26f. Further, (alphabet key)*(telephone number)*(user abbreviation) input from the operation section 20 is output to the signal line 26e and displayed on the display section 22.

In step 34B, it is determined whether the mode for reading the phone number and user abbreviation stored in correspondence with the one-touch key is selected (i.e., rF, , r2).
(whether or not the key was pressed) is determined. If the mode of reading the stored phone number and user abbreviation corresponding to the one-touch key is selected (i.e. "F
”.

If the "2" key is pressed), the process advances to step 548. Further, if the mode for reading the phone number and user abbreviation stored in correspondence with the one-touch key is not selected (that is, if the "F" or "2" keys are not pressed), the process proceeds to step S50. move on.

In step 348, the telephone number and user abbreviation stored in correspondence with the one-touch key are read and displayed on the display section 22. Specifically, the alphabet is manually written by an operator. After outputting a signal representing the alphabet to the signal line 24a, a read pulse is generated to the signal line 28g. after that,
The signal on the signal line 24a is input manually to recognize the telephone number and user abbreviation corresponding to the alphabet. The control circuit sends its telephone number and user abbreviation to signal line 26e.
The information is output to the display unit 22 and displayed on the display unit 22.

In step S50, it is determined whether automatic calling using a one-touch key has been selected. If automatic calling using the one-touch key is selected, the process advances to step S52. Furthermore, if automatic calling using a one-touch key is not selected, the process advances to step S42.

In step S52, the telephone number for automatic dialing and the user abbreviation corresponding to the telephone number are stored in the memory circuit 2.
Read from 4. The control circuit sends the telephone number to signal line 2.
5d, a transmission command pulse is sent to the signal line 26c, and automatic transmission is performed using the one-touch key.

Step 354 represents a pre-procedure.

In step 35B, it is determined whether the stored user abbreviation of the other party matches the originator user abbreviation actually obtained from the communication partner. As a result, if they match, proceed to step S58.
If they do not match, the process advances to step S62.

Step S58 represents execution of image transmission.

Step 5liO represents a post-procedure.

In step S62, the translator is informed that the user abbreviations do not match. Specifically, a start pulse is generated on the signal line 21ih.

Normally, the telephone line 2a is connected to the telephone side, but at the time when facsimile transmission is started in accordance with the sending of this start pulse, the telephone line 2a is connected to the present facsimile machine side. Then, at the time when the facsimile transmission is completed, the telephone line 2a is connected to the telephone side again.

In the embodiments described so far, it has been assumed that dialing the other party is done with a one-touch operation, but it is also possible to dial by speed dialing, dialing by using the numeric keypad attached to the main body of the facsimile machine, or dialing from the telephone M4. It is also possible to do this.

Here, when dialing from the numeric keypad or dialing from a telephone, it is possible to dial any number. Therefore, when dialing a certain telephone number, there is a possibility that the user abbreviation of the other party corresponding to this telephone number has not yet been registered. In this case,
At that point, an instruction can be given to the operator, and the information can be transmitted without checking the user abbreviation of the other party based on the operator's judgment. Alternatively, it is also possible to interrupt the transmission at that point and register a new user abbreviation corresponding to the telephone number.

Furthermore, in this embodiment, it is determined whether the user abbreviations of the sender who sends the image information match, but the sender sends the user abbreviation of the person to whom the image information is to be sent to the receiver, and the receiver determines whether there is a match. You can also do it like this. Furthermore, although this embodiment has been explained using a facsimile machine as an example, it is not limited to facsimile machines.
The present invention can be applied to any data communication device that performs data communication via a line such as telex.

[Effects of the Invention] As explained above, the present invention is configured to communicate data after confirming the identification information of the communication partner. (Even if the company changes from Company A to another Company B)
Since data communication is not performed during the process, there is no need to send important documents to the wrong recipient, and reliable data communication can be performed.
