Abstract

PURPOSE:To improve the operation efficiency of a transmitting side FAX by transmitting a document automatically to plural receiving side FAXs if the document is transmitted confidentially only one time from the transmitting side FAX to the receiving side FAX. CONSTITUTION:In the case when the same confidential document is transmitted from the FAX(S) of Tokyo head office to the FAX(A), the FAX(B), the FAX(C) of Osaka branch, the FAX(S) adds a confidential ID code and the telephone number of a transferred destination, etc., to a signal, and transmits it confidentially. The FAX(A) having received it extracts the confidential ID code by an IO code extracting part 3, and sends it to an ID code collating part 4. At this time, when the transmitted confidential ID code coincides with the previously registered one, the new signal is generated by an NSS frame generating part 6, and is transmitted confidentially to the FAX(B) through a transmitting part 7 together with a picture stored in a picture data storage part 2. In the FAX(B), the signal is processed similarly, and is sent to the FAX(C) confidentially.

Description

[Detailed description of the invention] [Table of contents] Overview Industrial field of application Prior art (Figure 5) Means for solving the problems to be solved by the invention (Figure 1) Working examples (Figure 2) ~Figure 4) Effects of the invention [Summary] Regarding the confidential transmission file transfer method, the facsimile device that receives the confidential data analyzes the confidential ID and, if it is a certain specific code, sends it to the destination facsimile device that has been registered in advance. In a transmission file transfer method in which a facsimile signal received from a sending facsimile machine is transferred to another facsimile machine for the purpose of confidential transfer, the facsimile machine is provided with an image data holding means and an ID code verification means, and a When data such as a confidential ID code and the phone number of the forwarding destination facsimile device is added and sent confidentially, and the receiving facsimile device extracts the confidential ID code and matches the ID code of the forwarding destination registered in advance. By performing confidential transfer to the destination facsimile device, confidential transmission can be performed from the initial source to multiple destinations in one confidential transmission.

[Industrial application field]

The present invention relates to a confidential transmission file transfer method, and more particularly to a confidential transmission file transfer method that can reduce long-distance communication when transmitting confidential documents via facsimile communication.

[Conventional technology]

Conventionally, confidential communication has been performed in facsimile communication.

Figure 5 is a schematic diagram of the conventional confidential transmission method.
(S) is the sender's facsimile (hereinafter referred to as FAX, for example, the FAX in the Tokyo head office), FAX (A), FAX (
B), FAX (C) is the receiving side (7) FAX (for example, a branch in Osaka).

Now, for example, you can send the same important document from FAX (S) to multiple locations such as FAX (A), FAX (B), and FAX (C).
), if you wish to send a confidential document to each address, please send by FAX (S
) to FAX (A), FAX (B), FAX (C
) and sent confidential documents over and over again to each of them separately.

That is, by repeating long-distance communication (between Tokyo and Osaka) many times, confidential documents were sent to multiple destinations.

[Problems to be Solved by the Invention] The conventional confidential communication as described above has the following drawbacks.

(1) Communication costs increase because the number of long-distance communications increases.

(2) Because the transmission time of the sender's FAX (S) becomes longer, the busy state becomes longer (as it continues, and other FAXs are
I can't even receive messages from.

In particular, during confidential transmission, the busy state becomes very long because the transmission time is longer than for normal communication due to ID code confirmation and the like.

The present invention has been made to solve these conventional drawbacks, and is aimed at, for example, making it possible to send a large number of identical confidential documents through long-distance communication. .

[Means to solve the problem]

In order to achieve the above object, the present invention is as follows.

FIG. 1 is a diagram showing the principle of a confidential transmission file transfer system according to the present invention, and the present invention will be described in detail below based on this diagram.

Now, for example, from the sending facsimile machine FAX (S) in the head office in Tokyo to the facsimile machines FAX (A), FAX (B), and FAX (C) in branches A, B, and C in Osaka, the same To send a confidential document, do the following:

First, a confidential ID code and confidential file information are added to the N5S (non-standard function setting) signal of the communication protocol from the FAX (S), and then the FAX (B) and (C) of the destination
) and send it confidentially to the recipient's fax machine.

When this confidential transmission is received by FAX (A) in Osaka branch A, the ID code extractor 3 extracts a confidential ID code from the NSS signal in the receiver 1 and sends it to the ID code collate unit 4. Along with this, the received image data is
It is stored in the image data storage section 2.

At this time, if the confidential ID code sent from the FAX (S) matches the ID code of the forwarding destination registered in advance, the NSSSS frame creator 6 sends the destination facsimile device (B) according to instructions from the main control unit 5. removes the telephone number of the forwarding destination facsimile machine (C) and creates a new NSS signal with the telephone number of the forwarding destination facsimile machine (C) added, and sends it to the transmitter 7.
The image data stored in the image data storage section 2 is taken out and sent to the transmission section 7.

This transmitter 7 performs confidential transmission to the transfer destination FAX (B).

FAX (B) processes the signal in the same manner as FAX (A), and performs confidential transmission to FAX (C).

In addition, FAX (B) and FAX (C) are the above FAX
It has the same configuration as (A) and has the same function, and any number of receiving-side FAX machines can be used instead of just three.

In addition, FAX (A), FAX (B) and FAX (
Confidential documents for each FAX itself in C) are stored in the image data storage section 2, and are printed and retrieved only when they match the input confidential ID code.

[Effect]

With the configuration as described above, if the FAX (S) sends confidential transmission only once to the receiving FAX, the receiving side will receive the FAX.
From AX (A) to FAX (B) and back to FAX (B
) to FAX (C).

Therefore, for example, when sending multiple confidential documents from Tokyo to Osaka, only one communication is required between Tokyo and Osaka, which are long distances. Also, with FAX (S), you only need to send to FAX (A), so FAX (S) is F, AX (A) ~
The busy time is reduced to about 1/3 compared to the case of transmitting to each FAX (C).

〔Example〕

Embodiments of the present invention will be described below with reference to FIGS. 2 to 4. FIG. 2 is a schematic diagram of a confidential transmission file transfer method that is an embodiment of the present invention.

In Figure 2, FAX (S) is the sender's FAX (for example, a FAX in the Tokyo head office), FAX (A), FAX

It is a figure showing S, S frame structure.

In this NSS frame configuration, ADR,S is the address field, CTRL is the Will i wholesale field, F is the frame code, and CCITMBR is the C
CITT members code, MFT is our company code.

Also, the ID is the transfer ID code, INF.

to I N F a are each information fields,
For example, a confidential ID is written in INF2, and confidential file information such as linear density is written in INF4.

Next, multiple confidential documents are faxed (S) to the receiving FA.
The case of sending to X will be explained.

For FAX (S), the AD shown in Figure 4 of the NSS signal is
I NF from RS. In addition to the normal NSS frames up to
Enter the D code, the confidential file information in the information field INF 4, and then add the fax phone numbers of branch B (station B) and branch C (station 0), which are the destination faxes, and send it to the receiving side fax. Send a confidential message to.

When this is received by FAX (A), which is a FAX on the receiving side, the ID code extraction unit 11 extracts a confidential ID code from the NSS signal received by the reception unit 10.

The extracted ID code is checked by the ID code matching unit 12 into the ID code registered in advance in the 10 code file unit 13.
It is checked against the D code.

In addition, the confidential document sent from the FAX (S), that is, the image data, is stored in the image data bath section 15 (.

As a result of the above verification, if the confidential ■I) code sent from the FAX (S) matches the ID code of the transfer destination, the NSS frame creation unit 16, the NS as shown in FIG. 4(B)
Create an S frame configuration.

That is, in order to transfer a confidential document from FAX (A) to FAX (B), a new NSS signal from which the FAX telephone number of office B is removed is created and sent to the transmitter 17.

At the same time, the confidential document stored in the image data buffer section 15 is sent to the transmitting section 17, and following the NSS signal, this confidential document is also transferred to the FAX (B).

Next, when FAX (B) receives the NSS signal transferred from FAX (A), it sends an NSS signal with the NSS frame structure as shown in FIG. Create.

In this case, since this is the final transfer, the NSS frame structure is such that all the phone numbers of the destination FAX are removed, and since the transfer is complete, the ID, that is, the transfer request ID, is also removed. Confidential transfer from FAX (B) to FAX (C).

In the above case, if the document is a confidential document for the own station, the image data temporarily stored in the image data storage section 15 is put into the file 19 via the file control section 18.

When the ID code matches the ID code input from the keyboard 20, the user can print the received confidential document using the printer 21 and receive the received confidential document.

In addition, as the receiving fax, branch A1 branch B in Osaka
, the FAX within branch C has been described, but the present invention is not limited to such cases; for example, FAX
(A), FAX (B), and FAX (C) may be FAXes from different departments within one branch.

〔Effect of the invention〕

As explained above, according to the present invention, there are the following effects and effects.

(1) The sending FAX can send a confidential document to multiple destinations in one confidential transmission.

Therefore, the time during which the sending side FAX is busy is shortened.
