Abstract

PURPOSE:To provide the facsimile equipment in which internal information of an opposite facsimile equipment is acquired by devising the facsimile equipment such that a concerned facsimile equipment sends a session start command CSS signal while an internal information transfer request signal is added to a function identifier of the CSS signal and the opposite facsimile equipment returns an RSSP signal while adding function acceptance is added to a function acceptance identifier of the RSSP signal. CONSTITUTION:A communication control section 18 adds a function identifier to a CSS signal and sends the resulting signal to an opposite facsimile equipment 2 to start session. The opposite facsimile equipment receives the function identifier added to the CSS signal and adds a function acceptance identifier to an RSSP signal and a communication control section 28 sends the resulting signal to a concerned facsimile equipment 1. A main control section 10 of the concerned facsimile equipment 1 discriminates it that the opposite facsimile equipment 2 accepts the transfer request signal based on the function acceptance identifier of the RSSP signal received by the communication control section 18.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile device, and more particularly to a device for transferring internal information of a facsimile device on the other side to a facsimile device on the operator side.

[0002]

2. Description of the Related Art As a conventional facsimile apparatus, a "facsimile apparatus" described in Japanese Patent Application Laid-Open No. 2-134974.
Is proposed. This is a means for accumulating internal information indicating the state of the device according to a predetermined file format, a means for transmitting a file transfer request signal from a remote device, a means for receiving the signal, and a remote device. And a means for transferring the designated file as a data portion by a communication means for transmitting image data.

In this system, a facsimile machine on the operator side sends a transfer request to a partner facsimile machine by adding a transfer request to a CDUI signal, and when the partner facsimile machine receives the CDUI signal, the transfer request added to the CDUI signal is sent. Judgment is made and internal information is transmitted.

[0004]

However, in the conventional facsimile machine, the facsimile machine on the operator side sends the request signal for collecting the internal information of the facsimile machine on the CDUI signal. Since the facsimile machine on the operator side has not confirmed whether or not the request signal was received by the operator, if the facsimile machine on the other side is a facsimile machine that cannot accept the request signal, the facsimile machine on the operator side Even though the internal information is being received, the partner facsimile machine transmits the image data, so that there is a problem that correct internal information cannot be collected and an unpredictable error may occur.

Therefore, according to the present invention, a request signal for collecting internal information is added to the function identifier of the session start command CSS signal and the request signal is transmitted to the facsimile machine of the other side, and when communicating with the facsimile machine having this function, the RSSP signal of the RSSP signal is transmitted. It is an object of the present invention to provide a facsimile device which immediately returns the communication when it is added to the function acceptance identifier and returned, and it is confirmed whether or not it is accepted, and when communicating with a facsimile device that does not have this function.

[0006]

The invention according to claim 1 is
In order to solve the above-mentioned problems, in a facsimile machine provided with communication control means for controlling a predetermined communication protocol via an ISDN line and storage means for storing internal information of the apparatus, the communication control means receives the information. The communication control means adds a transfer request signal for requesting the transfer of the internal information stored in the storage means of the partner facsimile machine to the function identifier of the session start command CSS signal. Then, the determination means determines whether or not the partner facsimile machine has received the transfer request signal based on the function acceptance identifier of the session start positive response RSSP signal received by the communication control means from the partner facsimile machine. It is characterized by making a judgment.

In order to solve the above-mentioned problems, the invention according to claim 2 judges that the judgment means is based on the function identifier of the CSS signal received by the communication control means. If it has been added, the communication control means adds the function acceptance identifier to the RSSP signal and transmits it, forms the internal information stored in the storage means into a fixed format, and internally stores it in the document user information command CDUI signal. The feature is that information is placed and transmitted.

In order to solve the above-mentioned problems, the invention according to claim 3 prints the internal information received by the communication control means, and the display means for displaying the internal information received by the communication control means. And, when the communication control means receives the internal information of the partner facsimile apparatus, the internal information is printed by the printing means and displayed by the display means.

[0009]

According to the first aspect of the present invention, the communication control unit adds the function identifier to the session start command CSS signal and sends the session start command CSS signal to the other facsimile machine to start the session.
The partner facsimile machine sends the session start command CS
Accepting the function identifier added to the function identifier of the S signal,
A function acceptance identifier is added to the RSSP signal, and the RSSC signal is sent to the own facsimile apparatus by the communication controller. The main control unit of the own facsimile device determines that the other facsimile device has received the transfer request signal based on the function acceptance identifier of the RSSP signal received by the communication control unit from the other facsimile device.

According to the second aspect of the present invention, the main control unit of the facsimile apparatus of the other party receives the C received by the communication control unit.
Judgment is made based on the function identifier of the SS signal, and as a result, C
When the internal information transfer request signal is added to the SS signal, the communication control unit adds the function acceptance identifier to the RSSP signal and transmits the internal information stored in the system memory into a fixed format. Once stored in the general-purpose memory, the internal information formed in a fixed format in the CDUI signal is transmitted by the communication control unit.

According to the third aspect of the present invention, the facsimile machine displays the internal information of the facsimile machine of the other party, which is stored in the general-purpose memory, on the operation display section in order of transmission. Further, the internal information of the other facsimile machine stored in the general-purpose memory is sent to the plotter and printed in order.
