Abstract

PURPOSE:To prevent the mis-transmission of facsimile, by storing a telephone number and an identification number of a communication opposite device and collating its identification number with that extracted from a signal transmitted from a receiver. CONSTITUTION:A receiver signal analysis circuit 1 extracts information of a CSI from a signal representing the response of a transmission opposite side. Further, a dial number detecting circuit 2 detects a number dialed by the operator. An ID (identification) number storage circuit 3 stores the telephone number of the communication opposite device and the ID number corresponding to it and the stored ID number is read out based on the number detected at the circuit 2. A collating circuit 4 fetches CSI information of the circuit 1 and the stored ID number in the circuit 3, checks the presence of coincidence and when coincident, a coincidence signal ''1'' is generated and when dissident, a dissidence signal ''0'' is generated. When the signal goes to ''1'', the transmission is attained and when the signal goes to ''0'', the transmission is made disable.

Description

[Detailed description of the invention] [Field of application of the invention] The present invention relates to an apparatus for preventing erroneous facsimile transmission.

[Prior art]

To send a facsimile, set the original, dial, confirm the response sound from the other device, press the communication switch, start reading the original, or determine whether communication is possible based on the status of the communication lamp. Take steps.

However, with this, the only means of confirming the other party's machine is a single tone of 2100 Hz indicating that the facsimile machine has automatically answered, and the only way to confirm the other party's machine is a single tone of 2100 Hz, which indicates that the facsimile machine has automatically answered.
If a call is made to another facsimile machine due to a misconnection or the like, the operator will not know that it is a mistake and will simply send the call without realizing it.

Taking all of this into account, it has recently been called ID display, and has a function that displays ID numbers such as the receiving party's phone number or device number on all transmitting parties using a signal sent from the receiver to prevent erroneous transmissions. There are many things that are out there.

This general control procedure will be fully explained with reference to FIG. The figure shows a transmission procedure between a transmitter and a receiver. The facsimile receiver is
It automatically responds with a ringing tone (RGT) and sends out a CED signal indicating that it has automatically responded. The transmitter operator listens to the CED signal and activates the transmitter (SEND).
ON). Following the CED signal, the receiver sends a DIS signal indicating the function of its own device and an NS signal indicating that it is a non-standard device.
In addition to the F signal (used independently by each manufacturer except in certain areas), the C signal contains information such as the receiver's telephone number or device number.
Send all 8I signals.

The transmitter that receives this informs all transmitting side operators of the ID number of the other device by displaying it on the C8I's full operation panel.

According to this method, incorrect dialing or incorrect connection can be detected by checking the ID display at the time of transmission, but if there is an oversight on the part of the operator, the result will be an erroneous transmission. When facsimile transmission is performed without operator intervention, such as automatic transmission, the 10 display does not function as a function to prevent erroneous transmissions, and erroneous transmissions cannot be prevented.

[Purpose of the invention]

It is an object of the present invention to eliminate all of the drawbacks of the prior art, and to prevent erroneous transmissions in facsimile transmissions and to improve the reliability of communication. The present invention provides a device for preventing erroneous facsimile transmission.

[Summary of the invention]

The gist of the present invention is to store the telephone number of the communication partner device and its corresponding ID number, detect the dialed telephone number, and extract the ID number from the previously stored ID number and the signal sent from the receiver. By checking the numbers, it has been determined whether or not the transmission can be sent.

Hereinafter, the present invention will be fully described in detail with reference to the drawings.

[Embodiments of the invention]

FIG. 2 is an embodiment of the erroneous transmission prevention device of the present invention. The receiver signal analysis circuit 1 includes the NSF, C8I shown in FIG.
, extracts C8I information from the DIS signal. The dialed number detection circuit 2 detects the number dialed by the operator.

The ID number storage circuit 6 stores the telephone number of the communication partner device and its corresponding ID number, and stores the number based on the number detected by the dialed number detection circuit 2 that detects the number dialed by the operator. The ID number is read.

The verification circuit 4 compares the C8I information of the receiver signal analysis circuit 1 with the I
It is checked whether the ID number stored in the D number storage circuit 6 and the ID number are all taken in and match. When there is a match, a match signal "1" is generated, and when there is a mismatch, a mismatch signal "0" is generated.

Send is possible when the match signal is “1” (SEND ENABL)
E) When the mismatch signal is "0", transmission is disabled.

FIG. 6 is a diagram of another embodiment in which an automatic transmission function is added. The newly added elements are an automatic dial generating circuit 5, a dial number indicating circuit 6, a second verification circuit 7, a mark reading 9 circuit 10, and an AND gate 14.

The mark reading circuit 10 includes a sensor 12 that detects reflected light when the original 20 is irradiated with light from the light source 11, and a mark detection determination circuit 16. Here, the manuscript 20 is

Taste frX.

At the time of automatic transmission, the all-dial number designation circuit 6 takes in the other party's number, etc. detected by the mark detection and determination circuit 16. The automatic dialing circuit 5 performs automatic dialing based on instructions from the dial number designating circuit 6.

On the other hand, the all-dial number detection circuit 2 detects the calling number and the like. The ID number recording circuit 6 receives the detection notification number from the detection circuit 2 and outputs the corresponding ID number.

Further, the receiver signal analysis circuit 1 performs analysis and outputs C8I information. The verification circuit 4 thoroughly checks whether the C8I information and the ID number match.

Further, the verification circuit 7 checks whether or not there is a match between the detection number of the dial number detection circuit 2 and the dial number of the dial number designation circuit B. When there is a match, a match signal n1u is generated, and when there is a mismatch, a mismatch signal "'0" is generated.

On the other hand, the collation circuit 4 also generates a match signal "1" when there is a match, and a mismatch signal "0" when there is a match.

When a match is obtained in both the matching circuits 4 and 7, a send enable signal (SEND EN
A-BLE) i occurs. In embodiments in which at least one of the signals is disabled, the transmission enable signal is input to a transmission control circuit in a facsimile machine (not shown) and serves as control information for causing transmission. Furthermore, when the signal is a transmission prohibition signal, it is similarly input to the transmission control circuit and becomes control information for prohibiting transmission. In addition, by appropriately displaying whether these transmissions are possible or not, the operator's operations are aided.

〔Effect of the invention〕

According to the present invention, it is possible to automatically detect erroneous transmissions.
