Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a facsimile communication method, and more particularly, the present invention relates to a facsimile communication method, and in particular, by rewriting identification data stored in the memory of the facsimile device installed at a remote location, The present invention relates to a facsimile communication method that enables polling operations between

Prior Art In conventional facsimile devices, in order to rewrite data that is distinguished from telephone numbers, terminal identification data (ID), or image information such as the number of errors and number of sheets stored in the memory of the facsimile device, it is necessary to The operator must perform some operations on the facsimile device itself, such as operating switches attached to the device to rewrite data in the memory, and it is not possible to rewrite these data from a remote location. It was impossible.

This has the disadvantage that polling operations, etc., cannot be executed due to a mismatch in the terminal identification codes, and furthermore, if the terminal identification code information in the memory has been destroyed, transmission becomes impossible. .

Purpose The present invention eliminates the above-mentioned conventional drawbacks by making it possible to rewrite identification data stored in a facsimile device at a remote location to enable polling operations. To provide a facsimile communication method that enables a polling operation with a facsimile device of the other party without going to a place where the device of the other party is installed and without requiring an operator of the device of the other party to take any trouble.

Embodiments Hereinafter, details of the present invention will be explained based on embodiments shown in the drawings.

FIG. 1 and the following illustrate one embodiment of the present invention. FIG. 1 shows a block diagram of a control circuit, and in the illustrated example, a system configuration according to CCITT Recommendation G is adopted.

In FIG. 1, reference numeral 1 denotes a line control circuit, which is a circuit for connecting a telephone line and a facsimile machine.

Also, those indicated by code 2 are CCITT Recommendation V27ter
The high-speed modem for image data specified in V21, and the one indicated by code 3, are the low-speed modems for control procedure signals specified in V21, respectively.
It is connected to the.

Reference numeral 5 indicates a known document reading unit using a CCD image sensor, etc., 6 indicates an image recording unit using a thermal head, etc., and 7 indicates an instruction to send a data rewriting request signal to the other party's facsimile device. The button 8 is an 8-bit on/off switch for setting the terminal's own terminal identification code.

Based on the above circuit configuration, the present invention uses the low-speed modem 3 to send a rewriting request signal to rewrite the terminal identification code of the other party's facsimile device to the terminal identification code of the sending device.
This is intended to be transmitted using facsimile control procedure signals specified in CCITT Recommendation T30.

By the way, FIG. 2 shows an NSF (non-standard device) signal from the other party's facsimile device indicating that it is possible to transmit a rewrite request signal. In FIG. 2, the symbol 9 is an 8-bit flag sequence indicating "01111110". 10 is an 8-bit address field, 11 is an 8-bit control field, and 12 is an FCF (fax control field) that indicates the signal name of the rewrite request signal.
The format of the NSF signal is set.

Further, reference numeral 17 is a frame check sequence.

Codes 9 to 12 and 17 are CCITT recommendations, respectively.
Specified by T30.

On the other hand, code 13 is the CCITT members code.
14 is a manufacturer code, 15 is an 8-bit terminal identification code (ID) stored in its own memory, and 16 is a key code X indicating that the terminal identification code can be rewritten.

When the device of the present invention receives an NSF signal including the manufacturer code and key code I can do it.

In FIG. 3, reference numeral 18 is the FCS format of the NSS signal, 19 is a terminal identification code set by the 8-bit switch shown as 8 in FIG. 1, and 20 is a key code Y for requesting data rewriting.
It is.

An NSS signal containing the manufacturer code and key code Y as described above is used to request that the terminal identification code (ID) of the other party's facsimile device be rewritten to its own identification code.

FIG. 4 explains the communication procedure when using the device of the present invention.
When the manufacturer code and key code
Send NSS signals.

Next, the MCF is acknowledged from the other device.
When the (message confirmation) signal is returned, the device sends a DCN (disconnection command) and completes the series of procedures.

Next, specific control operations will be explained based on the flowchart shown in FIG.

First, when the control section is started, it is determined in step _S1 whether or not an instruction button for transmitting a data rewriting request signal to the other party's machine, indicated by reference numeral 7 in FIG. 1, has been pressed.

If it is not pressed, proceed to step _S2 , which is a normal facsimile operation.

If it is determined that the instruction button 7 has been pressed, the process advances to step S ₃ to begin signal reception, and if the signal has been received, the process advances to step S ₄ to determine whether or not the DIS signal has been received. If the NSF signal has been received, the process proceeds to step _S5 , where it is determined whether the NSF signal has been received. If it is determined that an NSF signal has been received, the process proceeds to step _S6 , where the manufacturer code is detected. If the manufacturer code is detected, the process advances to step _S7 , where it is determined whether the key code -X is included. If the key code X is included, the process advances to step _S8 , and an NSS signal containing the manufacturer code and key code Y is sent. In this NSS signal, the terminal identification code of the terminal itself inputted from the 8-bit on/off switch shown by reference numeral 8 in FIG. 1 is set.

Then, the process proceeds to step _S9 , where it is determined whether or not a signal has been received.
Proceeding to _S10 , it is determined whether or not it is an MCF signal,
If it is an MCF signal, it sends a DCN signal and ends the transmission operation.

If it is determined in step _S3 that no signal has been received, the process proceeds to step _S12 , where the signal is not received for a certain period of time.
For example, it is determined whether 35 seconds have elapsed or not. If 35 seconds have elapsed, the transmission procedure is ended, and if not, the process returns to step _S3 .

If it is determined in step S ₄ and step S ₅ that neither the DIS signal nor the NSF signal has been received, the process also proceeds to step S ₁₂ and repeats the above-described operations.

Further, if it is determined in step _S6 and step _S7 that the manufacturer code and key code X are not detected, the transmission procedure is ended.

Furthermore, if it is determined in step _S9 that no signal has been received, the process proceeds to step _S13 ,
It is determined whether a predetermined time, for example 3 seconds, has elapsed, and if the predetermined time has elapsed, the line is released and transmission is stopped. If the time has not elapsed, return to step _S8 .

Furthermore, if it is determined in step _S10 that the signal is not an MCF signal, the transmission is similarly terminated.

Effects As explained above, according to the present invention, the identification data stored in the other party's facsimile device to enable the polling operation can be rewritten by transmission from the facsimile device at a remote location. If the polling operation cannot be executed due to a mismatch between the two devices, by matching mutual identification data from a remote location, the polling operation can be executed without requiring any trouble for the operators of both devices.
