Abstract

PURPOSE:To send a confidential telegraphic message even to a device without a reception data storage section by adopting the constitution that a confidential text is sent when a pass word sent from an opposite device and a predesignated destination pass word are coincident in a confidential test sender side equipment. CONSTITUTION:In sending a confidential telegraphic message from a FAX 1 to a FAX 2 without any reception data storage section, the operator stores a picture data read from an original or requested for relay transmission from other device to a storage section 9 in the FAX 1. After the pass word stored inputted by the operator or received by the relay transmission request is stored in pass word storage section 1a, the FAX 2 is called. The FAX 2 informs the absence of information in the reception data storage section. when the absence of the storage part is informed, a confidential notice section 5a of the FAX 1 sends a present confidential notice, and the operator of the FAX 2 receiving the confidential notice inputs the pass word by an operation display section 10 and sends the pass word by the control of the pass word transmission section 4a. A collation section 2a of the FAX 1 collates the received pass word with the pass word of a storage section 1a and when they are coincident, a picture data in the storage section 9 is sent to the line.

Description

[Detailed Description of the Invention] [Summary] In confidential telegram communication, if the receiving device does not have a storage unit for accumulating received data, the receiving device notifies the sending device of this and also allows the device operator to input an operation. The received PIN code is sent to the sending device, and the sending device checks the received PIN code with the pre-specified destination party's PIN code, and if they match, sends a confidential message. It becomes possible to send a confidential message to a device that does not have a storage unit for storing data.

[Industrial application field]

The present invention relates to a confidential function of a facsimile device, and more particularly to a confidential communication method that enables sending a confidential message to a device that does not have a storage section for storing received data.

In recent years, facsimile document communication has spread to various fields.
Functions such as relay relay sending to multiple other facsimile devices via a relay facsimile device, confidential communication that temporarily stores received image information in the storage unit, and outputs the image only when a specific password is entered. As facsimile machines become more sophisticated, inexpensive facsimile machines that are not equipped with a storage section for storing received image data are also becoming more popular. Therefore, in a facsimile communication system, there is a need for a confidential communication method that allows communication of confidential messages even to facsimile machines that do not have such a storage unit.

[Conventional technology]

An example of transmitting a confidential message to FAX 2 (hereinafter referred to as FAX 2) is shown below. The same reference numerals indicate the same objects throughout the figures.

In the figure, a reading unit 7 has a function of reading a document with an image sensor (not shown) and converting it into image data.

The recording unit 8 has a function of recording characters and figures on recording paper according to the received signal.

The storage unit 9 is a memory that stores received image data or image data read from the reading unit 7.

The operation display unit 10 includes a send button, a receive button, a destination phone number,
It is equipped with operation buttons for inputting transmission time, etc., and a display for checking communication status and displaying input data, etc.

The main control unit 11 performs facsimile functions by controlling each unit to transmit and receive image data via a line, read/write to the storage unit, read/record image data, read operation buttons, and display on the display. Let it be carried out.

The line control unit 6 has a function of transmitting and receiving image data and commands according to the line interface and protocol.

Therefore, the procedure for transmitting a confidential message to FAX 2 from FAXI or by relaying FAX'l is as follows: ■ In FAX 1, by performing the document separator, pressing the confidential button, manually entering the password, etc. is read by the reading section 7, and the image data is stored in the storage section 9. Or, when receiving a request from another device to relay a confidential message with the destination party's password, the received image data is stored in the storage unit 9.

(2) The FAX 1 makes a call to the FAX 2 and transmits the image data read from the storage section 9 as well as the password.

(2) The FAX 2 stores the received image data in the storage unit 9 and displays the receipt of the confidential message. When the device operator inputs the password, the FAX 2 checks the password against the password received from the FAXI, and if they match, reads the image data from the storage section 9 and records it in the recording section 8.

Therefore, in the FAX 2, the received confidential message is temporarily stored in the storage unit 9, and when the password input by the device operator matches the destination password, it is configured to be read out from the storage unit 9 and output as a record. has been done.

[Problem that the invention seeks to solve]

As described above, according to the conventional method, when receiving a confidential message, the receiving device stores the received image data in the storage unit 9 and combines it with the received destination's PIN code and the PIN code input by the device operator. Since the received data is compared and when there is a match, it is output from the storage section 9 and recorded, there is a problem that the confidential function cannot be used for facsimiles that do not have a storage section for storing received data.

[Means for solving problems]

FIG. 1 shows a block diagram of the principle of the present invention.

In the figure, reference numeral 1 denotes a password storage means for storing the password of the destination party, 2 a collation means for comparing the password with the password stored in the password storage means 1 when the password is received from the recipient's device, and 3 a receiver. Notifying means for notifying the other device of the presence or absence of a storage section for storing data; 4 is a password transmitting means for transmitting the password when the password is inputted;

Therefore, the confidential message sending side device can send a confidential message to a device that does not have a storage unit for storing received data when the PIN code sent from the other device matches the destination PIN code specified in advance. is configured to send.

[Effect]
