Description

[Detailed description of the invention] [1! ! [Required] In a facsimile machine that has an image memory and is equipped with multiple service functions including relay request communication and confidential communication, these service functions can be transferred from a general facsimile machine that does not have these service functions. When transmitting an image signal to a facsimile machine equipped with a facsimile apparatus, a predetermined service function of a receiving station can be selectively executed from a transmitting station.

[Industrial Application Field] The present invention relates to a facsimile device, and more particularly, to a facsimile device having an image memory and having multiple service functions including relay request communication and confidential communication.

The facsimile device has an image memory that temporarily stores received image data, and is configured to select and execute service functions such as relay broadcast request communication and confidential communication based on a service function selection signal transmitted from the transmitting station. There are things that have been done.

Here, relay broadcast request communication refers to sending image signals of the same document to multiple facsimile machines from a transmitting facsimile machine that does not have a broadcast fg function to a receiving facsimile machine that has a broadcast communication function together with the recipient information. This means that the receiving facsimile machine transmits the image signal of the original document and performs broadcast notification (i) in response to a request from the transmitting facsimile machine.

On the other hand, confidential communication refers to receiving (f) from a sending facsimile device.
The original image signal and confidential password are sent to the fi facsimile device, and the receiving facsimile device sends the received image signal to -H.
This refers to visualizing the received image signal as a recorded image by storing it in the image memory and inputting the correct confidential password.

In other words, when selecting and executing these service functions,
In addition to the original image signal, a means for transmitting broadcast destination information and a confidential password is also required.

[Prior Art] By the way, in a conventional facsimile machine, the relay return request communication and the control information of the confidential communication 3 are included in the procedure signal.

FIG. 6 is an explanatory diagram of the signal sequence of the <G3 procedure based on the CCITT recommendation (T, 30). In the figure, TX is a transmitting facsimile device, hereinafter referred to as a transmitting station. Rx
is a receiving facsimile machine, hereinafter referred to as a receiving station. When the transmitting station TX calls the receiving station Rx, the receiving station Rx sends a CED (called station identification), N5, to the transmitting station Tx.
F (non-standard function), C31 (called terminal identification) and DIS
A procedure signal consisting of (digital identification signal) is transmitted. Here, the NSF signal is the called station CCITT recommendation (T, 3
0) This is an optional signal indicating capability outside the range, and the identification information regarding the presence or absence of relay request communication capability and confidential reception capability is the corresponding N.
It is assigned to a part of the SF signal.

By receiving these procedure signals transmitted from the receiving station Rx, the transmitting station Tx determines the TSI (transmitting terminal identification), N
Send SS (non-standard function settings) and TCF (training check) to receiving f4 RX. Here, NSS
The signal is a digital command response from the transmitting station Tx to the information contained in the NSF signal transmitted from the receiving station RX, and the broadcast destination information and confidential password information are included in the NSS signal. The receiving station Rx receives these procedure signals transmitted from the transmitting station Tx, and thereby transmits a CFR (reception readiness confirmation) to the transmitting station TX. By receiving the CFR signal, the transmitting station TX transmits PIX (original 81 image information, 1
page) and EOP (end of procedure) to the receiving station RX. The receiving station Rx transmits an MCF (message confirmation) to the transmitting station TX, and the transmitting station Tx transmits a DCN (disconnect command) to the receiving station RX, and the series of procedures ends.

[Problems to be Solved by the Invention] However, the data structure in the information field of the NSF signal and NSS signal in the procedure signals of such conventional facsimile machines differs depending on the manufacturer.

Therefore, there is a drawback that relay broadcast request notification (E7) and confidential communication cannot be executed between devices manufactured by different manufacturers in many cases.

The present invention has been made in view of these points, and
It is an object of the present invention to provide a facsimile device that can perform relay return request communication and confidential communication even between devices manufactured by different manufacturers.

[Means for Solving the Problems] FIG. 1 is a block diagram of the principle of a facsimile apparatus according to the present invention. In the figure, 1 is a transmitting facsimile device without a relay communication function or a confidential communication function, 2 is an exchange, and 3 is a receiving facsimile device according to the present invention having a relay request communication function or a confidential communication function. The receiving facsimile device 3 is provided with an image memory 4 and a push-button dial selection signal detection section 5 for detecting the push-button dial selection signal transmitted from the sending facsimile device 1.

[Operation] After the sending facsimile device 1 starts facsimile communication,
The receiving facsimile device 3 receives a push-button dial selection signal from a telephone (not shown) for selecting the relay return request communication function or the confidential communication function of the receiving facsimile device 3.
Send to. When the push-button dial selection signal detection unit 5 of the receiving facsimile device 3 detects the push-button dial selection signal, the receiving facsimile device 3 starts accepting relay broadcast destination information and confidential password information.

The facsimile image signals received as relay broadcast request communications or confidential communications are temporarily stored in the image memory 4. Then, the 1iIiii image stored in the image memory 4 is relayed to a predetermined destination in the case of a relay request communication, and visualized as a recorded image in the case of a confidential communication.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings.
