Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a confidential transfer control device in a facsimile machine having a confidential document transmission / reception function.

[0002]

2. Description of the Related Art Conventionally, a facsimile apparatus having a confidential function for transmitting a document which is not desired to be seen by others has been put into practical use. This confidential fax machine
The received image information is temporarily stored in the image memory, and the stored image information is not output unless a preset password is input to the facsimile device.

Conventionally, as a control device thereof, as disclosed in, for example, Japanese Patent Application Laid-Open No. 6-268877, when personal data is received, the personal information recognition means determines that the image data is image data addressed to an individual. Whether or not there is personal information is judged, and if it is addressed to an individual, the personal information is recognized. Then, when it is determined that the image data is not the image data addressed to an individual, the image data management means having a function of taking out the data from the storage device and printing the data immediately prints the image data. Further, when it is determined that the data is addressed to an individual, the image data management means stores the image data in the storage device, and then recognizes the image data only when it is recognized and input by the personal information acquisition means. It is known to print from a storage device.

[0004]

However, in the above-mentioned conventional confidential transfer control device, when it is determined that the data is addressed to an individual registered in the receiving terminal regardless of whether the confidential transmission is performed, the image data is transmitted. Since the management means stores and saves the image data in the recording device, the result is that the normal sending document addressed to the individual registered in the receiving terminal is also saved.

Also in the transfer control device having the facsimile function having the confidential reception function switching function, the operator on the receiving side needs to operate the key for the confidential transmission selection, or the confidential box number on the receiving side is set in advance. It is often inconvenient to handle on the sending side because it needs to be known.

Furthermore, when image data that has not been registered is sent to the receiving side, the image data management means immediately prints the data, which results in leakage of confidential information to the transmitting side, which results in confidentiality. It cannot serve as a transfer control device for sending.

The present invention has been made in view of the above-mentioned conventional problems. When a document, such as important or confidential, which is desired to be kept secret is sent from a device having a facsimile function without a confidential function. In addition, the confidentiality and security of the document can be secured, but the inconvenience in handling on the sending side is eliminated, in other words, the emphasis is not placed on sending, and confidentiality cannot be guaranteed. An object of the present invention is to provide an image transfer control device in which security can be ensured by rejecting confidentiality only for data and the confidentiality function can be easily used.

[0008]

In order to achieve the above object, the present invention provides a storage means capable of storing personalized data.

Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. FIG. 1 is a block configuration diagram of a confidential transfer control device according to the first embodiment of the present invention. In the figure, the system control unit 1 is composed of a microcomputer unit and manages and controls the entire confidential transfer control device. The image memory unit 2 is
This is a memory that temporarily stores image information and is used as a work area when storing and transmitting image information.

The operation display unit 3 is a liquid crystal touch panel display having functions such as various operation buttons, a numeric keypad, and a keypad. The operator arbitrarily operates the confidential control device, and the confidential control device sends information to the operator. It is for displaying a message or the like. It should be noted that a liquid crystal display is more convenient when entering a password, which will be described later. Reading unit 4
Is for decomposing a transmission document into pixels with a predetermined resolution and converting each pixel into a re-signal, and the output printing section 5 is for recording image information on recording paper and outputting it.

The communication control unit 6 executes transfer control according to a predetermined transmission control procedure, and is connected to a public line network through a modem 7 and a network control device 8 which modulate a transmission signal and demodulate a reception signal. Has been done. The compression / expansion unit 9 encodes the image information to be transmitted by a predetermined method to compress the information amount and restores the encoded received image information to the original image information.

The confidential control unit 10 develops the received image information in the image memory unit 2, detects the recipient name (destination name), and also detects whether it is confidential image information. The HDD 11 is a large-capacity hard disk drive that stores the image information determined by the confidential control unit 10 as confidential image information for each individual.

The confidential control device of this embodiment has the above-mentioned configuration and has the following operational characteristics. First, the operation procedure will be described. A password is set as a password for the recipient. This password is
This is a keyword necessary for outputting the received image information in the confidential reception mode, and it is set to the password registration mode from the operation display unit 3, and in this mode, the personal name and any password are input. The entered password is stored in the internal nonvolatile memory of the system control unit 1.

Since the personal name is searched upon reception, not only both the family name and surname but also the furigana and alphabets should be registered. For example, Mr. Even if it is transmitted in the alphabetical notation SUZUKI, it can be confidentially received.

The setting of the password in this confidential control device has the following highly convenient functions. For example, when the business card of the person himself / herself is read from the reading unit 4 and an arbitrary password to be set is input, the name of the business card is extracted and registered. In addition, the unentered part such as alphabet is
You can input from the keyboard of the liquid crystal touch panel. Also, if you use an auto input device that allows even people who do not have business cards to register by writing a password on the scanner and entering the password,
It is very convenient because it saves time and effort.

Next, the receiving operation of the confidential transfer control device of this embodiment will be described. When the transmission original is sent from the transmission side, the network control device 8 detects the calling signal at the reception side,
Connected to the device body. The communication control unit 6 responds to a control signal sent from the transmission side via the modem 7, executes a predetermined transmission procedure with the transmission side, and then sequentially receives the image signals to be transmitted in a memory.

FIG. 2 shows a communication protocol of the session document layer when the confidential transfer control device having the configuration shown in FIG. 1 performs confidential transmission / reception. In addition,
The session document layer is equivalent to the session layer, which is the fifth layer of the open system interconnection (OSI) standard, and exchanges information in synchronization with each other in order to coordinate two application processes well. This is to manage the interaction when communicating in the bidirectional simultaneous full-duplex mode or the alternate half-duplex mode, select the transmission mode, and control the transmission right.

In FIG. 2, when a command session start (hereinafter referred to as CSS) signal is transmitted from the transmitting side terminal, a response session start positive (hereinafter referred to as RSSP) signal is transmitted from the receiving terminal. . Next, the sending terminal sends a command document start (hereinafter referred to as CDS) signal, and then a command document user information which is image information.
A signal (hereinafter referred to as CDUI) is transmitted. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, it is temporarily stored in the image memory unit.

At this time, control is performed by the confidential control unit 10 by multitasking, and processing of procedures such as whether the received data is a confidential document or whether the name addressed to an individual is registered in the receiving terminal is performed. If the name addressed to the individual is a confidential document registered in the receiving terminal, the confidential control unit 10 causes the HDD to
The received confidential document is stored in the personal name directory on the large-capacity hard disk 11 to receive the confidential information.

When the transmission data is completed, the transmitting terminal side
A command document end (hereinafter referred to as CDE) signal is transmitted to notify the completion of transmission. Therefore, the receiving terminal side sends a response document end positive (RDEP) signal after confirming the reception completion, and automatically disconnects layers 2 to 4. The layers 2 to 4 mean the OS
The data link layer is the second layer in the I layer, the network layer is the third layer, and the transport layer is the fourth layer.

On the other hand, if the name addressed to an individual is a confidential document that is not registered in the receiving terminal, the confidentiality control unit 10 determines that confidentiality cannot be received and rejects confidentiality reception. That is,
As shown in FIG. 4, when the transmitting side transmits a CDUI signal which is image information and subsequently receives a CDE signal, a response document user information error (hereinafter referred to as RDUIERR) signal which is a confidential reception refusal signal is transmitted. , The layers 2 to 4 are automatically disconnected, and the received image information is erased from the image memory unit 2. At this time, it is desirable that the fact that the receiving terminal has performed the confidential reception refusal operation is displayed on the liquid crystal display or is printed out and reported.

If the transmitting terminal supports confidential control like the receiving terminal, the RDUIER is sent to the transmitting side.
It is desirable to send the R signal and send the cause report of the reject operation. In the present embodiment, the main cause of rejection by the receiving terminal is that a confidential document addressed to an individual who is not registered in the receiving terminal is sent. When sending such a document, it is necessary to delete the protect display term 12 shown in FIG. 5 or to perform personal registration on the receiving terminal side.

FIG. 3 shows the control operation of this control device. That is, when the CSS signal is first transmitted from the transmitting side terminal, the RSSP signal is transmitted from the receiving terminal.
Next, the transmitting terminal transmits the CDS signal and then the CDUI signal which is image information. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, the image information is temporarily stored in the image memory unit 2. At this time, control is performed by the multi-task control by the confidential control unit 10, and processing of procedures such as whether the received data is a confidential document or whether the name addressed to an individual is registered in the receiving terminal is performed (steps # 5 to #). 15).

At this time, if it is determined that the document is not a confidential document, the protect display term 12, for example, "secret, secret,
If there is no word such as "Confidential, Secret, CONFIDENTIAL, Confidential etc." that does not leak the contents of the transmission to a third party, transfer the control to the output printing unit 5 as a normal FAX and display the image information in the memory. Print.

Now, the transmitting terminal uses the CDUI which is image information.
After the signal transmission is completed, the CDE signal is subsequently sent to notify the end of the document data, and a command session end (hereinafter referred to as CSE) signal is sent. Therefore, the receiving side terminal confirms that the image information is surely received, returns a response session end positive (hereinafter referred to as RSEP) signal, ends the communication of the session document layer, and a series of The FAX reception process is completed (step # 20).

If the protect display term 12 is on the paper, it will be on the paper again, "Sir, sir, teacher,
Detecting a title such as "Kimi, Chan", the character string before the title is extracted (step # 25), and it is searched whether the character string is registered in the receiving terminal (step # 25).
30). If it is not registered, it is determined that confidential communication cannot be performed, and confidential reception refusal processing is performed (step # 35). That is, a confidential reception refusal signal RDUIERR is transmitted to the transmitting side, and the data in the memory is erased at once (step # 40). If the character strings before and after the title are registered in the receiving terminal, it is determined that confidential reception is possible, the image information is transferred to the HDD 11, and a series of operations is completed (step # 4).
5).

The confidential image information stored in this way is
The output is not printed until the person inputs the password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit 3 and inputting the registered password. At this time, when a plurality of sets of image information are received, if the image information to be output and printed can be selected, even if the user is busy, it is possible to first view the copies one by one.

As described above, in this embodiment, the F being received is received.
AX is not printed out immediately but is expanded in memory and is "secret"
Extract the protected display terms and address such as. At this time, if there is no protect display term, it is normally output as FAX. If the corresponding person is registered in the receiver, store the data in the personal directory of the large capacity hard disk,
If it is not registered, the confidential data cannot be confidentially deleted, and the data being received is immediately deleted and the sender is denied confidential confidentiality. The stored data has a protection function that can be printed out only by the person himself / herself, and has a FAX function that can be output by inputting a password.

Therefore, the confidential transmission function can be easily used even for image information sent from a facsimile apparatus having no confidential transmission function. If the received data is a confidential document, it is judged whether or not there is a person who can receive and output to the receiving terminal, and if there is no confidential information, the confidential information is rejected, and the received information is prevented from being leaked to a third party.

Next, a confidential transfer control device according to the second embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above. The control device of the present embodiment performs the receiving operation as follows. However,
The communication procedure in the session layer is the same as that in the first embodiment.

That is, from the transmitting side terminal, first, the CSS
When the signal is sent, the RSSP signal is sent from the receiving terminal. The transmitting terminal, after transmitting the CDS signal next,
A CDUI signal which is image information is transmitted. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, the image information is temporarily stored in the image memory unit 2. At this time, the control is performed by the multi-task control by the confidential control unit 10, and the procedure of processing such as whether the received image information is a confidential document or whether the name addressed to an individual is registered in the receiving terminal is performed (step # in FIG. 3). 5 to # 15).

The processing range is set within the range of the upper two-fifths of the first sheet of the received image information shown in FIG. 5, so that the CPU of the confidential control unit 10 is not burdened. In addition, it has an effect of not being erroneously detected as the protect display term 12 that is accidentally used in the text. This process is not performed for the second and subsequent sheets. At this time, if it is determined that the document is not a confidential document, that is, the protected display term 12 such as "secret, secret, secret, secret, CONFIDENTIAL, confidential etc." If there is no word displayed so as not to leak, the control is transferred to the output printing section 5 as a normal FAX and the image information in the memory is printed (step # 20 in FIG. 3).

When the print output is faster than the communication speed after the data in the memory is output, the print output may be directly performed without passing through the memory. Then, the sending terminal
Sends the CDUI signal, which is image information, and sends the CDE signal to notify the end of the document data.
Send SE signal. Therefore, the receiving side terminal confirms that the image information is surely received, returns the RSEP signal, ends the communication of the session document layer, and ends the series of FAX reception processing.

If the protect display term 12 is within the upper two-fifths of the paper, it will be again within the upper two-fifths of the paper. "Sir, lord, teacher, you, chan, M
r., Miss, Mrs., Ms. "etc. are detected, the character string before and after the title is extracted (step # 25 in FIG. 3), and it is searched whether the character string is registered in the receiving terminal ( Step # 30 in FIG. 3). If it is not registered, confidential reception is rejected because it cannot be confidential (step # 3 in FIG. 3).
5). That is, a confidential reception refusal signal RDU is sent to the transmitting side.
IERR is transmitted and the image information in the memory is erased at once (step # 40 in FIG. 3). If the character string before the title is registered in the receiving terminal, it is considered that confidential reception is possible.
Transfer image information to the large capacity hard disk of DD11,
A series of work is completed (step # 45 in FIG. 3).

The confidential image information stored in this way is not output and printed until the person inputs a password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit and inputting the registered password.

As described above, in this embodiment, the protect display term is searched for only in a predetermined range from the upper end of the sheet of the first page and the last page, and the FAX function that does not accidentally register the protect display term accidentally in the sentence is provided. I have it, so
The protect function can be operated for the FAX sent from the last page, and by specifying the search range, there is an effect that false confidential registration and unnecessary search time are not consumed.

Next, a confidential transfer control device according to the third embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above. The control device of this embodiment performs the receiving operation as shown in the flowchart of FIG. However, the communication procedure in the session layer is the same as that in the first embodiment.

That is, from the transmitting side terminal, first, CSS
When the signal is sent, the RSSP signal is sent from the receiving terminal. After transmitting the CDS signal, the transmitting terminal transmits CDUI which is image information. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, the image information is temporarily stored in the image memory unit 2. At this time, the multi-task control is performed by the confidential control unit 10, and it is determined whether the sending direction of the received data is correct. If the received data is upside down, normal printing may occur even if the protection display term 12 exists, so this is a very important process (steps # 105 to # 115).

FIG. 7 shows an example of the processing method. As shown in this figure, only the uppermost character string of the received data is fetched into the confidential control unit 10 and the character cutting process is performed. The extracted characters are normalized, thinning is performed, feature extraction is performed by connecting point end point extraction, and the like, and character recognition processing is performed by the pattern matching method. 18 on the database side
The character rotated 0 degrees is also registered. The result of character recognition does not return the character but returns the normal and reverse rotation of the character.

For example, as a result of character recognition of "su" indicated by reference numeral 13, it is recognized as "su" rotated by 180 degrees, and the result is stored in the register A. In this case, in the register A, "1" is stored in the column as indicated by reference numeral 14. Similarly, “Ma” and “Shi” are processed, and the result is stored in the register A.
At this time, the inverted “shi” may be erroneously recognized as “tsu” indicated by reference numeral 15, and “0” may be stored in the column of register A as indicated by reference numeral 16.
Since the probability of erroneous recognition is extremely small, it is sufficient to make a majority decision in the register A and make a judgment of normal rotation and inversion. Also,
If the sending direction of the received data is opposite, all data will be 1
The 80-degree rotation process is performed (step # 120).

Subsequently, the title is detected within the upper two-fifths of the paper (steps # 125, # 130). At this time, when the title is not detected, it is determined that the last page is received, the whole image information is received in the memory (step # 135), and after the CDE signal is received (step # 14
0), rearrange the data, and perform a procedure such as whether the received data is received image information or a confidential document, or whether the name addressed to an individual is registered in the receiving terminal (step # 14).
5). By processing within the range of the upper two fifths of the first sheet of the received image information shown in FIG.
The CPU of the confidential control unit 10 is not burdened, and the protection display term 12 accidentally used in the text is not erroneously detected.

In addition, by not performing this process for the second and subsequent sheets, the receiving process is not burdened. At this time, if it is determined that the document is not a confidential document, that is, the upper end 5 of the sheet.
Protective display terms within the range of 2/2, such as “secret, secret, secret, secret, CONFIDENTIAL, confidential et
If there is no word such as "c" displayed to the third party so as not to leak the contents of transmission, the control is transferred to the output printing section 5 as a normal FAX and the image information in the memory is printed (step # 150). ). At this time, if the print output is faster than the communication speed, the print output may be directly performed without passing through the memory.

Next, the transmitting terminal sends a CDU which is image information.
The transmission of the I signal is ended, the CDE signal is sent to notify the end of the document data, and further the CSE signal is sent. Therefore, the receiving side terminal confirms that the image information is surely received, returns the RSEP signal, ends the communication of the session document layer, and ends the series of FAX reception processing.

If the protect display term 12 is within the upper two-fifths of the paper, it will be within the upper two-fifths of the paper again, "sir, sir, teacher, you, Chan, Mr., Miss, Mrs., Ms. "etc. are detected, and character strings before and after that title are extracted (step # 15).
5) Then, it is searched whether the character string is registered in the receiving terminal (step # 160). If it is not registered, it is determined that confidential reception cannot be performed, and confidential reception refusal processing is performed (step # 165). That is, a confidential reception refusal signal RDUIERR is transmitted to the transmitting side, and the image information in the memory is erased at once (step # 170). If the character string before the title is registered in the receiving terminal, it is determined that confidential reception is possible, the image information is transferred to the large-capacity hard disk of the HDD 11, and the series of operations ends (step # 175).

The confidential image information thus stored is not output and printed until the person inputs a password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit and inputting the registered password.

As described above, in this embodiment, when the characters are turned upside down, it is recognized that the paper is sent upside down, the sending data is rotated 180 degrees, and only the predetermined range from the upper end of the paper is searched. Since it has a fax function that prevents accidentally registering protected display terms that are accidentally included in the fax text, it is possible to protect the fax sent by flipping the paper upside down, and the search range By designating, there is an effect that mis-confidential registration and useless search time are not spent and the paper ejection direction can be always output in a fixed direction.

Next, a confidential transfer control device according to the fourth embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above. The control device of this embodiment performs the receiving operation as shown in the flowchart of FIG. However, the communication procedure in the session layer is the same as that in the first embodiment.

That is, from the transmitting terminal, first, CSS
When the signal is sent, the RSSP signal is sent from the receiving terminal. Next, the transmitting terminal transmits the CDS signal and then the CDUI signal which is image information. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, the image information is temporarily stored in the image memory unit 2. When all image information has been sent, C
A DE signal is sent to notify the end of the document data, and a CSE signal is sent. Therefore, the receiving side terminal confirms that the image information is surely received, returns the RSEP signal, ends the communication of the session document layer, and ends the series of FAX reception processing.

Once all the image information has been stored in the memory in this manner, the confidential control unit 10 is controlled to determine whether the sending direction of the received data is correct (step # 205).
~ # 215). If the sending direction of the received data is opposite, all data is rotated by 180 degrees (step # 2).
20). Subsequently, the title is detected within the upper two-fifths of the paper (steps # 225 to # 230). At this time, if the title cannot be detected, it is determined that the title has not been received, the last page is rearranged into one page (step # 235), and the received data is received image information or a confidential document. , Performs processing such as whether the name addressed to the individual is registered in the receiving terminal (step # 240).

The processing range is set within the range of the upper two fifths of the first sheet of the received image information shown in FIG. 5, so that the CPU of the confidential control unit 10 is not burdened. In addition, it has an effect of not being erroneously detected as the protect display term 12 that is accidentally used in the text. This process is not performed for the second and subsequent sheets. At this time, if it is determined that the document is not a confidential document, that is, if the protected display term 12 such as "secret, secret, secret, secret, CONFIDENTIAL, confidential etc." If there is no word displayed to prevent the contents of the transmission from leaking, the control is transferred to the output printing unit 5 as a normal FAX and the image information in the memory is printed (step # 245).

If the protect display term 12 is within the upper two-fifths of the paper, it will be again within the upper two-fifths of the paper. "Sir, lord, teacher, you, chan, M
r., Miss, Mrs., Ms. "is detected, the character string before and after the title is extracted (step # 250), and it is searched whether the character string is registered in the receiving terminal (step # 250). 255). If it is not registered, it is determined that confidential reception cannot be performed, and confidential reception refusal processing is performed (step # 260). That is, the FAX number of the sender who is likely to be within the upper two fifths of the paper is detected (step # 265).

The detection method is to extract a number string following "FAX". If there is a fax number, it automatically dials that number (step # 270), sends the confidential rejection document that is standard equipment of this device, and erases the confidential received image information in memory at once (step # 275). ). On the other hand, a number that does not have a fax number and the name of the sender are extracted within the upper two-fifths of the paper (step # 280), and the confidential print refusal document that is standard equipment of this device is printed by the output printing unit 5. At the same time, the confidential received image information in the memory is collectively erased (step # 285). If the character strings before and after the title are registered in the receiving terminal, it is assumed that confidential reception is possible.
The image information is transferred to the first large-capacity hard disk, and the series of operations is completed (step # 290).

The confidential image information stored in this way is not output and printed until the person inputs a password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit and inputting the registered password.

As described above, in this embodiment, the person who should receive the FAX after detecting the protect display after disconnecting the line is F.
If it is not registered in the AX machine, TEL that may be described in the received FAX data will be extracted and automatic dial-up will be performed, and a confidential reception refusal report will be sent to the transmitter and the receiver because confidential reception cannot be performed. Erase the received data. In addition, if the extraction of the telephone number from the fax data fails, the receiver has a function to print the confidential receipt refusal report only.
You can reject the confidential information even after disconnecting the line.

Next, a confidential transfer control device according to the fifth embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above. The control device of this embodiment performs the receiving operation as shown in the flowchart of FIG.

FIG. 10 shows an example of the confidential mark 17 which the user wants to set arbitrarily. When the control device is set to the confidential registration mode and the confidential mark is read from the reading unit 4, the confidential mark is registered as a protect display symbol. The registered protect display symbol is displayed on the liquid crystal touch panel on the operation display unit 3 as shown in FIG. When the confidential mark is registered in this way, as shown in FIG. 12, it can be sent as a confidential document only by adding a simple confidential mark 17 in place of the protected display term 12 shown in FIG.

The control operation of the present control device shown in FIG. 9 is as follows. However, the communication procedure in the session layer is the same as that in the first embodiment. That is, when the CSS signal is first transmitted from the transmitting side terminal, the RSSP signal is transmitted from the receiving terminal. Next, the transmitting terminal transmits the CDS signal and then the CDUI which is image information. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, the image information is temporarily stored in the image memory unit 2. At this time,
Control is performed by the multi-task control by the confidential control unit 10, and it is determined whether the sending direction of the received data is correct (step # 30).
5 to # 315). However, if the sending direction of the received data is opposite, all the data are rotated by 180 degrees (step # 320).

Subsequently, the title is detected within the upper two-fifths of the paper (steps # 325, # 330). At this time, if the title is not detected, it is determined that it has not been received from the cover, the whole image information is received in the memory (step # 335), and after the CDE signal is received (step # 34
0), rearrange the data, and perform a procedure such as whether the received data is received image information or a confidential document, or whether a name addressed to an individual is registered in the receiving terminal (step # 34).
5). By processing within the range of the upper two fifths of the first sheet of the received image information shown in FIG.
In addition to the burden on the CPU of the confidential control unit 10, it is possible to prevent erroneous detection of the protect display term 12 that is accidentally used in the text.

This process is not performed for the second and subsequent sheets.
At this time, if it is determined that the document is not a confidential document, that is,
Protect display term 1 within the upper two-fifths of the paper
2. For example, "secret, secret, secret, secret, CONFIDEN
If there are no words such as "TIAL, Confidential etc." that prevent the contents sent to third parties from leaking, search for a registered confidential mark (step # 350). If no confidential mark exists, The control is transferred to the output printing unit 5 as a normal FAX, and the image information in the memory is printed (step # 355).

If there is a confidential mark, or if the protect display term 12 is within the upper two-fifths of the paper, it will be again within the upper two-fifths of the paper. , Lord, teacher, you, chan, Mr., Miss, Mr
s., Ms. "and the like are detected, the character strings before and after the title are extracted (step # 360), and it is searched whether the character string is registered in the receiving terminal (step # 36).
5). If it is not registered, it is considered that confidential communication cannot be performed, and confidential reception refusal processing is performed (step # 370 to step 37).
5). If the character strings before and after the title are registered in the receiving terminal, it is determined that confidential reception is possible, the image information is transferred to the large-capacity hard disk of the HDD 11, and the series of operations ends (step 380).

The confidential image information stored in this way is not output and printed until the user inputs a password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit and inputting the registered password.

As described above, the present embodiment is provided with the FAX function capable of arbitrarily setting the confidential protection display symbol, and the confidential function can be used only with the arbitrarily determined protection display symbol. It has the effect of saving you the trouble of writing.

Next, a confidential transfer control device according to the sixth embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above. Further, the control device of the present embodiment performs a receiving operation similarly to the fourth embodiment shown in FIG.

An example of the confidential refusal document sent to the sender when the confidential reception is rejected is shown. When the FAX number of the sender is described in the received confidential document, the FAX number can be extracted and sent as a confidential reception trouble. The contents report not only the name of the sender but also the time of occurrence and the cause of the trouble. In the confidential trouble report, write the sender's name at the top of the form and read, "The confidential document sent to January 16, 1996, around 3:00 pm (Taro Suzuki) was not registered on the terminal. We could not receive it.If you do not want to send it confidentially, please erase the word "secret" and resend it. ", Etc., are provided so that the trouble occurrence time and the cause of the trouble can be understood.

Further, the sender's FAX is added to the received confidential document.
A number without a number cannot be sent to the sender as a confidential reception trouble, so a trouble report will be made to the receiving terminal side. The contents report not only the name of the sender but also the time of occurrence and the cause of the trouble. In the confidential trouble report, the name of the recipient is stated at the top of the paper, and "January 16, 1996, about 3 pm (Jiro Suzuki), was confidentially transmitted, but your name is registered in this terminal. I could not receive because it was not done.
If you want to receive confidential information, please register your name on this terminal. "," Etc., so that the trouble occurrence time and the cause of the trouble can be understood.

As described above, in the present embodiment, since the report has the FAX function of reporting the sender, the destination information, and the arrival time, when the confidential reception is rejected, the sender, the destination information, and the arrival time can be known. The effect is that the sender can be requested to resend.

Next, a confidential transfer control device according to the seventh embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above.

FIG. 13 is a flow chart when the system administrator deletes a confidential recipient. For example, when the control device is used in a company or the like, a case may occur in which the user is moved while being confidentially registered in the system due to a change in affiliation. If the document is moved while registered for confidential reception, the received document can be printed out only by the person himself, which wastes the hard disk and causes trouble to the sender. Therefore, a simulation mode must be provided so that the system administrator can manage this system.

The system administrator enters the confidential deletion mode by simulation (steps # 405, # 410). When the deletion mode is entered, a list of all confidential registrants and the presence / absence of confidential reception are displayed, so the administrator can select a deletion candidate from the list (step # 415). It is confirmed whether or not confidential information has been received for the deletion candidate (step # 420). If it has not been confidentially received, it can be deleted as it is. If it has been received, a warning is displayed to confirm that you want to delete it again.

Here, if the administrator gives up the deletion, the confidential reception can be continued without deletion (step # 425). When the deletion is executed, the confidential registrant is deleted after sending or printing out the confidential refusal document as in the fourth embodiment (step # 430). When the confidential information is deleted (step # 435), the confidential information cannot be received when the confidential document is sent, and the confidential information is rejected.

As described above, the present embodiment is provided with a FAX function capable of canceling the registered person by the administrator, displays a warning when there is data in the registered person directory, and allows the system administrator to delete the data. It has a function to check and unregister when there is data, and to automatically dial the data sender and send a report of confidential receipt rejection, so that the administrator does not need the registrant name instead of the registrant. You can cancel the registration. Even if a confidential document is sent to the person who cancels the registration in this device, the contents cannot be viewed, so that there is an effect that the person who requests the registration cancellation can be left in peace.

Next, a confidential transfer control device according to the eighth embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above. The control device of the present embodiment performs a receiving operation as shown in FIG. However, the communication procedure in the session layer is the same as that in the first embodiment.

Now, the control device of the present embodiment performs the receiving operation as follows. That is, from the terminal on the transmitting side, first, C
When the SS signal is transmitted, the RSSP signal is transmitted from the receiving terminal. Next, the transmitting terminal transmits the CDS signal and then the CDUI signal which is image information. At the same time as the transmitted image information is decoded by the compression / expansion unit 9, the image information is temporarily stored in the image memory unit 2. At this time, control is performed by the multi-task control by the confidential control unit 10, and a procedure such as whether the received data is a confidential document or the name addressed to an individual is registered in the receiving terminal is processed (steps # 505- #). 51
5).

At this time, when it is judged that the document is not a confidential document, the protect display term 12 shown in FIG. 5, for example, "secret, secret, secret, secret, CONFIDENTIAL, confidential etc.
If there is no word displayed such that the contents sent to a third party do not leak, the control is transferred to the output printing unit 5 as a normal FAX and the image information in the memory is printed. At this time, if the print output is faster than the communication speed, the print output may be directly performed without passing through the memory.

Now, the transmitting terminal uses the CDUI which is image information.
The transmission of the signal is completed, the CDE signal is subsequently sent to notify the end of the document data, and the CSE signal is further sent. Therefore, the receiving side terminal confirms that the image information is surely received, returns the RSEP signal, terminates the communication of the session document layer, and completes a series of FAs.
The X reception process ends (step # 520).

When there is a protect display term in the paper, the titles such as "sama, lord, teacher, you, chan" that may be in the paper are detected again, and the character string before the title is extracted. (Step # 525), it is searched whether the character string is registered in the receiving terminal (step # 530). If it is not registered, it is determined that confidential communication cannot be performed, and confidential reception refusal processing is performed (step # 535). Also, if the capacity of the hard disk is insufficient, confidential reception refusal processing is performed (step # 540).

That is, a confidential reception refusal signal RDUIERR is transmitted to the transmitting side, and the data in the memory is erased at once (step # 545). If the character strings before and after the title are registered in the receiving terminal (step # 540) and the hard disk has enough capacity, it is considered that confidential reception is possible and the image information is transferred to the large capacity hard disk of the HDD 11 to perform a series of operations. Ends (step # 545).

The confidential information stored in this way is not output and printed until the person inputs a password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit and inputting the registered password. At this time, if a plurality of sets of image information are received, and the user can select the image information to be output and printed, even if the user is busy, even one copy can be viewed for the time being.

As described above, in this embodiment, when confidential reception is performed in a state where the storage device has a shortage of capacity, after the confidentiality is rejected, a warning that the storage device of the present control device has a shortage of capacity is issued. Therefore, since all confidential documents cannot be received, confidential information is rejected, and a warning of insufficient capacity is displayed or printed, which has the effect of improving the capacity shortage for the user.

Next, a confidential transfer control device according to the ninth embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above.

FIG. 15 shows an example of an apparatus in which the user can arbitrarily set the protected display term, confidential mark 17, and title search range. When the control device is set to the confidential registration mode, it is displayed on the liquid crystal touch panel which is the operation display unit 3. The user can expand the range by moving the search area above and below the area designation range line 18.
As a result, a FAX format area that is frequently used by the user can be designated as the protected display search range.

The designation operation of the protected display search range in the control device of this embodiment is a setting operation as shown in FIG. When the confidential setting mode is entered, the designated line and the paper size of the protect display search range are displayed on the operation display unit 3. Therefore, the user should set the protect display search range from the frequently used paper position by empirical rules. You can

For example, if it seems that a FAX having a protect display term near the center as shown in FIG. 16 is often used, the protect display search range needs to be expanded to about two fifths to three fifths. There is. Therefore, when the confidential setting mode is entered and the search area is moved vertically with the finger or the like on the area designation range line 19, the area of the confidential setting search range can be expanded in association with the movement of the finger on the liquid crystal touch panel side.

As described above, in the present embodiment, since the protect display term and the search range of the destination name field are provided with the FAX function which can be arbitrarily set by the user, by setting the search range of the protect display term arbitrarily, The search range can be expanded. Therefore, confidential reception can be surely performed without changing the frequently used FAX format.

Next, a confidential transfer control device according to the tenth embodiment of the present invention will be described. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above.

First, when a CSS signal is transmitted from the transmitting side terminal, an RSSP signal is transmitted from the receiving terminal. Next, the transmitting terminal transmits the CDS signal and then the CDUI signal which is image information. At this time, if the line is disconnected by the other party's terminal, the communication control unit 6 notifies that the communication has been cut off. At this point, confidential reception has not been completed, and it is determined that confidential transmission has been canceled by the partner terminal, and the confidentially received documents are collectively erased in the image memory 2 and the large-capacity hard disk of the HDD 11.

Also, it is reported that there was a confidential reception refusal operation. If there is a fax number of the other party, it automatically dials that number and sends a confidential refusal document due to line disconnection. On the other hand, a number without a FAX number and the name of the sender are extracted, and the confidential print refusal document due to line disconnection is printed by the output printing unit 5.

In this way, when communication is interrupted due to an unexpected accident by the partner terminal during confidential reception, it should be sent again from the partner terminal. In this embodiment, therefore, an incomplete confidential document is rejected as a confidential file, thereby effectively preventing the storage device from being wasted.

Next explained is a confidential transfer control device according to the eleventh embodiment of the present invention. The system configuration of the confidential transfer control device according to this embodiment is the same as the system configuration of the first embodiment shown in FIG. 1 above.

First, when the CSS signal is transmitted from the transmitting side terminal, the RSSP signal is transmitted from the receiving terminal. Next, the transmitting terminal transmits the CDS signal and then the CDUI which is image information. At this time, when there is a line disconnection due to a failure by this terminal and the power is turned off, a flag is stored in the non-volatile memory to store that the power was turned off during reception, and the time is stored.

When the power is restored, the system controller 1
Goes to see if there is a flag in the non-volatile memory that stores the fact that the power is turned off. When the flag is set, the system control unit extracts the FAX number of the other party from the confidential document received at that time, automatically dials it, and sends the confidential refusal document due to the line disconnection.

On the other hand, when there is no FAX number, the name of the sender is extracted and the fact that the line has been disconnected by this system is reported. The stored incomplete confidential image information is not erased all at once and is not output and printed until the person inputs the password. The output can be printed by selecting the user's directory from the liquid crystal touch panel on the operation display unit and inputting the registered password. At this time, when a plurality of sets of image information are received, if the user can select the image information to be output and printed, even if the user is busy, even one copy can be viewed for the time being.

As described above, in the present embodiment, during confidential reception,
If communication is interrupted due to an unexpected accident by the terminal side, this terminal has a means to report that it was blocked during confidential reception after recovery. When the communication is interrupted, it is possible to immediately know that confidential reception was in progress by reporting that the terminal was interrupted during confidential reception after returning.

You can reject the confidentiality even after cutting the line.

According to claim 2, when the protect display term is searched, if the characters are turned upside down, it is recognized that the paper is sent upside down, the sending data is rotated 180 degrees, and the first sheet is sent. Also, since the search is performed only from the upper end of the paper on the last page to the specified range, it is possible to protect the FAX that is sent by turning the paper upside down. There is an effect that the paper discharge direction can always be output in a constant direction without spending confidential registration and useless search time.

[0100]

According to the third aspect of the present invention, a FAX function for arbitrarily setting the confidential protection display symbol is provided.
Since the confidential function can be used only with the protect display symbol that is arbitrarily decided, there is an effect that the trouble of writing "confidential" can be saved.

According to claim 4 , since the administrator is provided with a FAX function capable of canceling the registrant, the administrator can cancel the registration of the unnecessary registrant name on behalf of the registrant. it can. Even if a confidential document is sent to the person who cancels the registration in this device, the contents cannot be viewed, so that there is an effect that the person who requests the registration cancellation can be left in peace.
