Abstract

PURPOSE:To obtain the coincidence between terminal identification codes from a remote place and to attain a polling operation by rewriting the data stored in a facsimile device of the remote side with the transmission given from a main facsimile device. CONSTITUTION:The signal is received if the push of an indication button 7 is decided. In this case, whether a digital identification signal DIS is received is decided and the reception of a non-standard device NSF signal is decided if the reception of the signal DIS is confirmed. When the reception of the NSF signal is confirmed, the maker code is detected. In this case, it is decided whether a key code X is included. When the code X is included, a non-standard device setting NSS signal containing a key code Y is transmitted. Then the own terminal identification code is set into the NSS signal. When the NSS signal is received, it is decied whether the received NSS signal is equal to a message confirming MCF signal. Then a cut instruction DCN signal is transmitted if the NSS signal is equal to an MCF-fold value.

Description

DETAILED DESCRIPTION OF THE INVENTION TECHNICAL FIELD The present invention relates to a facsimile machine, and more particularly to a facsimile machine configured so that data on the other party's facsimile machine can be rewritten from a remote location.

Prior Art In a conventional facsimile machine, in order to rewrite the data stored in the memory of the facsimile machine, such as the telephone number, terminal identification code (ID), or image information such as the number of errors and the number of sheets, it is necessary to Operator Nagisa himself must perform some operations on the facsimile machine itself, such as operating switches attached to the device and rewriting data in the memory, and these data must be rewritten from a remote location. It was impossible.

As a result, polling operations and the like cannot be performed 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 has been made in order to eliminate the above-mentioned drawbacks of the conventional technology, and an object of the present invention is to provide a facsimile device configured so that data on the other party's facsimile device can be rewritten even from a remote location. It is said that

EXAMPLES Hereinafter, the present invention will be explained in detail based on examples shown in the drawings.

Figure 1 and the following diagrams explain one embodiment of the present invention.
The figure shows a block diagram of a control circuit, and in the illustrated example, a system configuration according to CCITT Recommendation GIII 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.

The instruction button 8 for transmitting the data rewrite request signal is an 8-bit on/off switch for setting the own terminal identification code.

Based on the circuit configuration described above, 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 machine to the terminal identification code of the sending device. However, it is intended to be transmitted using facsimile control procedure signals specified in CCITT recommendation T30.

By the way, FIG. 2 shows the N5F (non-standard device) signal of the other party's facsimile device indicating that it is possible to transmit a rewrite request signal. In Figure 2, the symbol 9 is an 8-bit flag sequence "01111110".

Further, reference numeral 17 is a frame check sequence.

Codes 9 to 12.17 are defined by Tsuretsure CCIT Recommendation T30.

On the other hand, numeral 13 is a CCITT member's 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 indicating that the terminal identification code can be rewritten. It is code X.

In the device of the present invention, when an NSF signal including the manufacturer code and key code X as described above is received, the NSS (
Non-standard device settings) signals can be transmitted.

In FIG. 3, numeral 18 is NSS (FCS of i
Format, 19 is a terminal identification code set with an 8-pin switch shown by reference numeral 8 in FIG. 1, and 20 is a key code Y for requesting data rewriting.

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 machine be rewritten to its own identification code.

FIG. 4 explains the communication procedure when using the device of the present invention.

Next, if an MCF (message confirmation) signal is returned from the other device as an acknowledgement, the DCN will be sent from this device.
(disconnection command) to end the series of steps.

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 device, indicated by reference numeral 7 in FIG. 1, has been pressed.

If it has not been pressed, the process advances to step S2, which is a normal facsimile operation.

If it is determined that the instruction button 7 is pressed, the process advances to step S3 and signal reception begins, and if the signal has been received, the process advances to step S4, where it is determined whether or not the DIS signal has been received. If it has been received, step S
Proceeding to step 5, it is determined whether an NSF signal has been received. If it is determined that the NSF signal has been received, the process proceeds to step S6, where the manufacturer code is detected. If a manufacturer need is detected, the process advances to step S7, and it is determined whether the key code -X is included. If 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 out. The own terminal identification code inputted from the 8-bit on/off switch shown by reference numeral 8 in FIG. 1 is set in this NSS signal.

Then, the process proceeds to step S9, and it is determined whether or not the signal has been received. If the signal has been received, the process proceeds to step S10, and it is determined whether or not it is an MCF signal. sends the DCN signal and sends it (ends the i operation).

If it is determined in step S3 that no signal has been received, the process proceeds to step S12, where it is determined whether a certain period of time, for example 35 seconds, has elapsed, and if the lifting weight has elapsed, the transmission procedure is terminated; If the time has not elapsed, the process returns to step S3.

If it is determined in steps S4 and S5 that the DIS signal and the NSF signal have not been received, the process also proceeds to step S12, and the above-described operations are repeated.

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.

Further, if it is determined in step S9 that no signal has been received, the process proceeds to step S L3, where it is determined whether a predetermined time, for example 3 seconds, has elapsed, and if it has elapsed, the line is released and transmission is stopped. do. If the time has not elapsed, the process returns to step S8.

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

Effects As is clear from the above description, according to the present invention, in a facsimile machine equipped with 11 memories for storing data distinguished from image information such as a terminal identification code or the number of errors and number of sheets, the data can be stored. Since the structure is equipped with a means for sending a data rewrite request signal requesting rewriting, the data stored in the other party's facsimile device can be rewritten by transmission from the facsimile device side, and the terminal In cases where polling cannot be performed due to mismatch in identification codes, etc., polling becomes possible because terminal identification codes can be matched from a remote location.

Furthermore, even if data such as a terminal identification code stored in the other party's facsimile device is destroyed, it is possible to rewrite the data from a remote location with the original data such as the destroyed terminal identification code.
