Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a facsimile machine having a confidential reception function.

[0002]

2. Description of the Related Art FIG. 6 is a block diagram showing a conventional facsimile apparatus. In the figure, 11 is a communication control unit that performs device control and communication control, 12 is an image information storage unit that stores image information, 13 is an operation unit provided for various function settings and telephone number input, and 14 is A reading unit for reading a transmission document, a recording unit 15 for recording received image information on recording paper, and a line control unit 16 connected to a telephone line 21.

Next, the operation will be described. The facsimile machine executes the communication procedure shown in FIG. 7 or 8. Here, FIG. 7 shows T.T. The so-called standard procedure according to 30 and FIG. 8 likewise shows the non-standard procedure.

When the facsimile machine serves as the receiving side, first, the line controller 16 detects a call signal (CI) sent from the telephone line 21. Then, the communication control unit 11 creates NSF (non-standard function identification signal), CSI (called terminal identification signal) and DIS (digital identification signal). Then, after sending out CED (callee identification signal) to the telephone line 21 via the line controller 16, the NSF,
CSI and DIS (actually, modulated waves for them) are sent to the telephone line 21 via the line control unit 16.

Further, if the transmitter is from the same manufacturer as the receiver, TSI (transmission terminal identification signal) and NSS (non-standard function setting signal) are generally sent from the transmitter, and the transmitter is the same manufacturer. If not, TSI and DCS (digital command signal) are sent. Therefore, the communication control unit 11 receives them via the line control unit 16.

Next, TCF (training check)
When the message is normally received, the communication control unit 11 sends out a CFR (reception preparation confirmation signal). Then, since the transmitting side transmits the image information, the communication control unit 11 receives the image information, performs the necessary processing, and then outputs the image information to the recording unit 15 or the image information storage unit 12.

By the way, the facsimile communication may include a confidential communication function so that a document can be transferred between two specific parties. To perform confidential communication,
The transmitting side turns on the bit for confidential communication in the NSS according to the instruction input by the operator. Then, when the communication control unit 11 on the receiving side detects the bit, it stores the received image information in the image information storage unit 12. Then, a predetermined password, for example, included in NSS is added to the image information.

After that, when a confidential document output instruction and a predetermined password are input to the operation unit 13 on the receiving side, the communication control unit 11 compares the password with the password added to the image information, and If they match, the image information in the image information storage unit 12 is output to the recording unit 15.

[0009]

Since the conventional facsimile apparatus is configured as described above, it is necessary to use NSS for performing confidential communication, and as a result, confidential communication can be performed only between facsimile apparatuses of the same manufacturer. There was a problem that communication could not be performed.

The present invention has been made to solve the above problems, and an object of the present invention is to obtain a facsimile apparatus capable of realizing confidential communication even if the transmitter is manufactured by another manufacturer.

[0011]

And a communication unit in the procedure storage unit, and if they match, a comparison unit that stores the received image information in the image information storage unit and an operation unit to which the password and the image information output request are input. Then, when the image information output request and password are input to this operation unit,
The output control unit compares the password with the password in the procedure storage unit, and delivers the image information in the image information storage unit to the recording unit if they match.

According to another aspect of the present invention, the facsimile apparatus includes a code storage unit that stores a specific code together with a password, and an image information storage unit that stores image information.
When a communication procedure signal at that time matches a specific code at the time of reception, a comparison unit that stores the received image information in the image information storage unit, and an operation that inputs a password and an image information output request When an image information output request and a password are input to this unit and this operation unit, the password is compared with the password in the code storage unit, and if they match, the output control that transfers the image information in the image information storage unit to the recording unit And a section.

[0013]

When the communication procedure of the current communication matches the communication procedure stored in advance, the comparing unit in the invention of claim 1 treats the received document at that time as a confidential document.

Further, if there is a code that matches the code stored in advance in the communication procedure of the current communication, the comparing section in the invention of claim 2 treats the received document at that time as a confidential document.
