Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a communication device such as a facsimile device, and more particularly to a communication device having a confidential function.

(Prior Art) Conventionally, a facsimile apparatus having a confidential function has been proposed and implemented in order to transmit information only to a specific partner.

In such a facsimile machine, the data transmitted in the confidential communication mode is temporarily stored in a memory device such as a hard disk, and a person who knows the personal identification number or code attached to the data corresponds to the receiver. There is a configuration in which the contents can be retrieved only when the personal identification number is input.

At this time, the receiver that has received the confidential communication does not display that fact at all, or only displays that the confidential communication has been received.

However, in such a conventional facsimile apparatus having a confidential function, only a specific person can utilize the function, and a plurality of persons cannot share the confidential function, which is inconvenient. there were.

For example, in order for more than one person to use it, it is necessary for all of those involved to be aware of the personal identification number, and confidentiality will be released at least among these persons. Therefore, the meaning of confidential communication is diminished.

Therefore, in the conventional confidential communication of the facsimile, it has been practically used only when the confidential information is transmitted to a specific person or a specific group.

This inconvenience may be partly due to the fact that the content of the confidential notification partner had to be made visible once it could not be easily recognized.

(Object of the Invention) It is an object of the present invention to provide a communication device such as a facsimile device capable of being used by a plurality of people while eliminating the above-mentioned drawbacks of the conventional device and maintaining a confidential function.

(Structure of the Invention) In order to achieve the above object, the communication apparatus of the present invention extracts only the address area of the received image information or other data and decodes it, and then the required display apparatus or this It is characterized in that it is configured to output the decoded portion and the communication content as encoded to the recording unit.

If necessary, a recognition code such as an ID number is also used to decode the communication contents once stored via the ID number, and displayed by a hard copy such as thermal recording or a soft copy means such as an LCD display. It is characterized by being configured to do.

Hereinafter, a facsimile apparatus will be described as an example of a communication apparatus of the present invention in detail with reference to the accompanying drawings.

FIG. 1 is an explanatory view showing an example of recording an original document for transmission used in the present invention. For example, an upper area A of the original sheet 1 is used as an area for writing a receiver's name, and an lower area B is used for communication contents. The area to be described.

When transmitting an image of an original document described above by a facsimile apparatus, generally, the main scanning is performed in the right direction in the figure and the sub-scanning is performed in the vertical direction to read a black-and-white or color pattern on the original document.
It is digitally encoded according to the encoding method specified by ITT (International Telegraph and Telephone Consultative Committee) and sent to the communication line.

Therefore, the address area A defined in FIG. 1 is specified, for example, by counting the number of main scanning lines. That is, the length at which the number of main scanning lines is the required number is defined as A, and the recipient's name is described in this section.

FIG. 2 is a block diagram showing an embodiment of the present invention, in which an image information signal transmitted based on an original document divided into areas as described above is input to a modem 3 via a telephone line 2. The output converted into a digital signal by the section is input to the decoding circuit 4.

The decoding circuit 4 decodes a signal coded by (MH or MR) based on the CCITT standard, and its output is divided into two, one to the main scanning number counting circuit 5 and the other to the selection circuit. 6
Are input to.

The selection circuit 6 is controlled by the output of the main scanning number counting circuit 5, and the signal described in the recipient name description area of the original 1 is the signal from the decoding circuit 4 in a hard copy of a thermal recording device or the like. 7 or a soft copy 8 such as an LCD display or the like, while in the communication content area B of the original 1, the output of the signal from the decoding circuit 4 is blocked, and the output from the modem 3 is branched instead. Then, the signal obtained by inputting to the recording pattern generation circuit (pattern generator) 9 is output to the recording device 7 or 8.

Further, the DATA input shown in the figure, that is, the other input end input to the decoding circuit 4 is based on an unencoded signal once recorded on a recording paper or recorded in another memory as described later. This is the terminal used when restoring the pattern of the ID circuit, and the ID circuit 10 and the keyboard which are also connected to the decoding circuit 4.
Reference numeral 11 and the like are devices for deciding whether or not to permit the communication content when it is restored. Further, the switch 12 and the resistor 13 and the like added to the selection circuit 6 output the selection circuit 6 concerned. Is a circuit for discriminating whether to output to hard copy 7 or soft copy 8.

The ID code to be input is input via the keyboard 11 and the ID circuit 10, and only when the ID code matches the ID registered in advance in the decoding circuit 4 or the ID described in the transmission original, the decoding circuit If 4 is configured to function normally, the confidential function can be sufficiently exerted.

For reference, FIG. 3 shows a pattern example in which a transmission signal encoded according to the CCITT standard is printed as it is. In this case, since the transmitted signal has an extremely high bit rate (high speed), if one bit is recorded as it is in the size of one pixel, there is a risk that the recording will be lost and an erroneous signal will result. , The pattern generation circuit 9
The pattern size is recorded as an appropriate size.

Further, FIG. 4 is a diagram showing the timing for identifying the recipient name describing area A, and the amount in the sub-scanning direction is performed by counting the number of main scans, as described above.

It should be noted that, although one embodiment has been described in the above description, the present invention is not limited to this and various modifications are possible.

(Effect of Device) As described above, according to the communication device of the present invention, the recipient's name is decrypted, and the contents are copied or recorded (stored) without being decrypted. It is possible to easily visually recognize to whom the contents are confidential, and even when a plurality of people use one communication device, the confidential function can be shared.
