2. Description of the Related Art Recently, various functions have been put to practical use as a relay function or a transfer function in a facsimile machine. For example, in the apparatus disclosed in Japanese Unexamined Patent Publication No. 4-132360, means for counting the number of received pages of facsimile communication is provided in a facsimile apparatus having a transfer function, and a page received from a transfer requester is received via a telephone line. When there are several call requests, it is possible to determine whether or not to transfer by returning the number of received pages counted above.

[0003]

The above-mentioned prior art is effective in that it can determine whether or not to transfer after confirming the number of received pages of the received facsimile communication, but the relay function in the facsimile apparatus is effective. Or, no consideration is given to using the transfer function to keep the communication cost low and perform the facsimile communication with the maximum communication amount. That is, in the actual facsimile communication, many documents are different from each other only in some pages out of a plurality of pages, and it is a great loss to keep the communication cost low if the document is honestly transmitted as it is. is there. The present invention has been made in view of the above circumstances, and it is an object of the present invention to solve the above-described problems in the conventional technique and to perform communication with the maximum communication volume while keeping the communication cost low. The present invention provides a facsimile machine.

BEST MODE FOR CARRYING OUT THE INVENTION In the facsimile apparatus according to the present invention, in a transfer request message to a relay destination facsimile apparatus, a document that a part of pages of a document including a plurality of pages is different is collectively transmitted. However, an instruction is given to each destination to transfer the edited document by appropriately combining these pages. As a result, only the number of pages transmitted from the relay destination facsimile machine to the final destination facsimile machine increases, but the number of transmission pages from the source facsimile machine to the relay destination facsimile machine becomes the minimum required number of pages, which reduces the communication cost. It is possible to keep it low. Hereinafter, embodiments of the present invention will be described in more detail with reference to the drawings.

The above means are connected to each other by a bus 12. The page information processing unit 13 described above performs an operation peculiar to this embodiment described below according to the program in the ROM 2. Hereinafter, the basic transmission procedure between the terminal devices connected to the ISDN basic interface and the protocol used for this will be described, and then the operation of the embodiment will be described.

As shown in FIG. 5, the calling terminal first sends a call setting message SETUP to the ISDN to request call setting with the called terminal. The ISDN sends a call setup message SETUP to the designated receiving terminal to make a call. Also, the IS that received the call setup message SETUP
The DN further sends a call setting acceptance message CALL_PROC to the calling terminal. When a call to the terminating terminal is initiated, the terminating terminal sends a calling message ALERT to the ISDN, and the ISDN sends a calling message ALERT to the originating terminal to inform that the calling has been initiated. Here, ALERT is repeatedly output at an appropriate cycle.

When the called terminal responds, the called terminal receives the ISD
A response message CONN is sent to N, and ISDN sends a response message CONN to the calling terminal to notify that the called terminal has accepted the call. Further, the ISDN sends a response confirmation message CONN_ACK to the receiving terminal, confirms the response of the receiving terminal, and the line is connected. After that, the data transmission is started. As described above, in the facsimile apparatus according to the present embodiment, communication is performed using the non-standard function by UUI added to the above-mentioned call setting message SETUP. Here, negotiation between devices that perform communication is performed using UUI as described below.

This will be described with reference to the flow charts shown in FIGS. In addition, the example explained below is
FIG. 2 shows an example in which a device on the transmission side requests a transfer destination to transfer a certain document. FIG. 2 is a transfer request process in the device on the transmission side, FIG. 3 is a transfer acceptance process in the device on the reception side, and FIG. 11A and 11B are explanatory diagrams of the operation of the distribution process in the device. When a transfer request is made from a device on the transmission side to a document, the fifth page of the document is different for each transfer destination, and the part corresponding to the fifth page of each transfer destination is
Suppose you are on pages 5, 6, 7, and 8 of this document.

In this case, as shown in FIG. 2, in the apparatus on the transmission side, as shown in FIG. 2, all eight pages of documents are subject to the transfer request, and as described above, the first page (P.1) to the fifth page (P.5). ) First

Then, a call setup message SETUP containing this UUI
Facsimile communication is performed by using (step 22).

A call setting message SET including the above UUI
UP transmits via ISDN D Channel Layer 3. This is because it is possible to prevent charging by disconnecting the line when it is determined that transfer is impossible as a result of analyzing this message by the receiving side device. As shown in FIG. 3, the device on the receiving side (the device that received the transfer request) sets up the call setting message SET including the UUI described above.
When the UP is received, its content is analyzed, and if it is determined that the transfer is possible, the added page information is referred to arrange the document information for each transfer destination (step 31), and the communication is ended.

Thereafter, the receiving side apparatus (the apparatus which has received the transfer request) prepares the first delivery document as shown in FIG.
The document is transmitted (steps 41 and 42), and thereafter, similarly, the document edited in the designated form is distributed to the four destinations.
According to the above-described embodiment, it is possible to realize a facsimile apparatus that can transmit a document, which is composed of a plurality of pages and is different only in some pages, while keeping the communication cost low. It should be noted that the above embodiment is an example of the present invention, and it is needless to say that the present invention is not limited to this.

For example, in the above embodiment, the call setting message SETUP is issued when a transfer request is made from the transmitting side device.
In the UUI added to, the four destinations (destinations) and the fifth page for each destination, the fifth page for each destination,
The example of setting the page information specifying the 6th page, the 7th page, and the 8th page is shown, but the delivery destination is SETU.
