A conversion method selection means 43 for determining whether to perform is provided.

As shown in FIG. 2, the schematic image conversion means 31 of the host computer 12 includes an image encryption key creating means 311 for creating an image encryption key, an image conversion area partitioning means 312 for partitioning an image conversion area, The image conversion area 313 for converting and encrypting the graphic image of the area specified by the image conversion area specification means 42 by a combination of well-known page description language graphics commands and the image conversion area specification means 42 Image clipping means 314 for deleting the schematic image of the area
Is provided.

The conversion schematic image reproducing means 32 of the host computer 12, as shown in FIG. 3, is an image encryption key input means 321 for inputting an image encryption key for reproducing the image encryption section, and this input. An image encryption key analysis unit 322 for analyzing the image encryption key input by the unit 321 and an image reproduction unit 323 for reproducing the image encryption unit using a graphics command of a well-known page description language are provided.

In the facsimile system having such a configuration, the graphic image transmission process shown in FIG. 4 is performed. First, in S1, the scanning means 21 reads the schematic image of the document, and in S2, the read schematic image is displayed in the schematic image display means 4.
1 is displayed on the display screen of the display device 13.
In this state, the operator operates the display device 13 in S3.
When the area to be encrypted is traced with the pen in the schematic image displayed in, the area is stored in the memory of the host computer 12 as an encrypted area. For example, on the display screen of the display device 13, as shown in FIG. 8, (X0, Y0), (X1, Y1), (X2, Y2
), (X3, Y3) and (X4, Y4
), (X5, Y5), (X6, Y6), (X7, Y7
When an area enclosed by () is specified, this encrypted area is stored in the memory as a command string shown below.

X0 _Y0 startpath X1 _Y1 linepath X2 _Y2 linepath X3 _Y3 linepath endpath X4 _Y4 startpath X7 _Y5 linepath X7 _Y5 linepath X7 _Y5 linepath Xp _Y5 linepath Xp _y5 When any one of the conversion A key 43a, the conversion B key 43b, the conversion C key 43c, and the conversion D key 43d arranged under 13 is selected, the selected cipher conversion method is stored in the memory. At this time, the cipher conversion method is stored as a conversion command, for example, 60 rotate 30 30 translate ...

Next, in S5, the graphic image conversion process is performed by applying the encryption conversion method selected by the operator to the encryption area specified by the operator. This graphic image conversion processing is performed by the graphic image conversion means 31, and this processing is as shown in FIG. That is, the memory for the graphic image designated in S11 is prepared. Subsequently, in S12, the graphic original image to be encrypted is divided. This is performed by the image conversion area dividing means 312 of the schematic image converting means 31,
As shown in (a), it is classified according to the contents specified by the operator.

Subsequently, in S13, it is checked whether the conversion is completed for all the sections, and if not, S
One image divided in 14 is converted using the conversion command sequence, and the converted image is written in the designated position of the memory in subsequent S15. Then, the processes of S14 and S15 are repeated until the conversion is completed for all the sections, and when the conversion is completed for all the sections, the image conversion process is completed. In this way, the schematic image shown in FIG. 9A is converted into an image as shown in FIG. 9B, that is, a kind of encrypted image is obtained.

In the processing of S5 in FIG. 4, the display device 1
If the operator sees the display screen of No. 3 and there is a graphic image that the operator is not satisfied with, the process of S2 to S5 is repeated by the redisplay operation. If the operator is satisfied with the converted graphic image, an image encryption key is created in S6. This is performed by the image encryption key creating means 311 of the schematic image converting means 31. The image encryption key is composed of an encryption area specification command created when the operator specifies the part to be encrypted, and a conversion command created when the conversion method is selected for the area specified by the operator. Then, the created image encryption key is saved. As the storage, for example, the data is printed on paper by the printing means 24 and stored, or if a floppy disk device is connected to the host computer 12, it is stored on a floppy disk. When the creation of the image encryption key is completed, the fax image of the partially encrypted graphic image is transmitted by facsimile by the FAX transmission means 22 of the facsimile apparatus main body 11 in S7.

Further, in this facsimile system, the reception processing of the encrypted graphic image shown in FIG. 6 is performed.
First, the graphic image received by the FAX receiving means 23 from the other party in S21 is displayed by the graphic image displaying means 41 of the display device 13 in S22. Further, in S21, the schematic image read from the document by the own scanning means 21 is
In S22, the schematic image display means 4 of the display device 13
Displayed by 1.

In this state, it is checked in S23 whether or not the image encryption key has been input. If the image encryption key has not been input, the graphic image displayed in S24 is printed by the printing means 2
4, and prints out on paper in S25. Further, when the image encryption key transmitted in advance in some form from the transmitting side is input, the schematic image is reproduced based on the image encryption key in S26, and the reproduced schematic image is displayed on the printing means 24. It is supplied and printed out on paper in S25.

The reproduction process of the graphic image in S26 is performed based on FIG. First, the image encryption key input in S31 is analyzed into a command for designating an area of a graphic image and a conversion command string used for image conversion to obtain a command for specifying an encryption area and a conversion command. Then, S3
For example, the command string converted into the image encrypted in 2 is
An encrypted image reproduction command sequence that returns the original images arranged in reverse order is used.

Subsequently, in S33, a memory for the encrypted image is prepared, and in S34, the graphic original image is divided by the designated number. Then, the one image divided in S35 is converted into an image by using the return command sequence for returning to the original image, and the image converted in S36 is written in the designated position in the memory. Then, the processes of S35 and S36 are repeated, and when the image conversion of all the sections is performed by the image reproduction command, this process ends. Thus, in FIG.
When the image shown in (b) is received, it can be converted back into the original image shown in (a) of FIG. 9 by converting the image.

Therefore, for example, as shown in FIG. 10 (a), when a manuscript containing confidential information a is transmitted by facsimile,
As shown in (b) of FIG. 10, the confidential item (a) can be converted into an encrypted image and can be transmitted to the other party by facsimile. Then, the receiving side receives the graphic image information including this encrypted image. If this is printed out as it is,
As shown in (b), you will receive the manuscript in which the confidential item (a) is encrypted. In addition, the conversion schematic image reproduction means 32
By inputting the image encryption key known in advance from the image encryption key input means 321 of FIG. 10, the original original image in which confidential information a is described can be printed out as shown in FIG.

As described above, since the part of the transmission document that is notified only to a specific person can be encrypted and transmitted, the image encryption key cannot be input unless the receiving person is a specific person. Nothing is known about the transformed parts. Further, if the person on the receiving side is a specific person, the image encryption key can be input, so that the manuscript in which the encrypted part is reproduced can be received.

When a document addressed to a specific person is received by a person other than the specific person on the receiving side, the encrypted part is printed as it is. Further, even when the image is received by an ordinary facsimile apparatus having no image encryption means or encryption reproduction means, the encrypted portion is printed as it is. In such a case, the printed manuscript is handed to a specific person, but the person who receives the manuscript can convert the encrypted part into a reproduced manuscript by using the device of this embodiment. .

This is shown below as a series of work procedures. (1) A graphic image including an encrypted part is printed out on paper by a facsimile machine. (2) Hand the printed paper to the intended recipient. (3) The receiver scans the received paper with the scanning means 21.
To read. The contents read at this time are displayed on the display device 13. (4) The receiver inputs the image encryption key using the image encryption key input means 321. As a result, the encrypted portion of the read schematic image is reproduced and returned to the original state, and the printing unit 24 prints on a new sheet.

Further, when erasing an item which is not desired to be notified to the other party or is not required to be notified to the other party in the original to be transmitted, the image clipping unit 314 of the schematic image conversion unit 31 performs an image clipping process. That is, the transmission document is scanned by the scanning unit 2 of the facsimile apparatus main body 11.
11, the clip path string is taken out from the image encryption key command in step S41, as shown in FIG. Then, in S42, a clip area is created by a non-zero rule with a clip path. Then, in S43, the original image is clipped in the clip area. That is, it erases. Finally, in S44, the image transmitting area 2 is transmitted by the FAX transmitting means 2
Transfer to 2. In this way, the graphic image partially erased by the FAX transmission means 22 is transmitted to the other party by facsimile.

For example, as shown in FIG. 12 (a), when a document containing a matter b which is not required to be known to the other party is transmitted by facsimile, the area of this matter b is set as shown in FIG.
It can be erased and sent to the other party by facsimile as shown in 2 (b). In this way, it is possible to delete and send items that you do not want to notify or need to notify the other party even if they are on the original, so you can erase the area of item B with correction liquid, cover this area with a separate paper etc. The troublesome work of is unnecessary. Also, without touching the manuscript directly,
It does not damage the manuscript.

Thus, the original to be transmitted is displayed on the display device 13, and the image encryption key creating means 311, the image conversion area dividing means 312 and the image converting means 313 of the schematic image converting means 31 are used on this display screen. By specifying the area to be encrypted and encrypting only the necessary part and sending by facsimile, the part to be encrypted and the part not to be encrypted in one page of the manuscript can be easily divided and sent by a simple operation. be able to. If the received graphic image information has an encryption unit, the received graphic image information is displayed on the display device 13, and on this display screen, the image encryption key input means 321 of the conversion graphic image reproducing means 32, the image encryption. The encrypted area is decrypted by using the deciphering key analysis means 322 and the image reproduction means 323 to reproduce the image, and the reproduced image can be displayed on the display device 13 or printed out on the paper by the printing means 24. . Further, in this case, if the image encryption key is not input from the image encryption key input unit 321, the received schematic image including the encrypted area can be printed out on paper as it is. Therefore, this facsimile system can be used in various ways according to the intended use and the versatility can be improved.

Further, the document to be transmitted is displayed on the display device 13 and the image clipping means 314 of the schematic image converting means 31 is used to erase the unnecessary or non-transmittable portion on this display screen. Can be sent by facsimile.

The image conversion means 313 performs encryption by performing image conversion by combining graphics commands of a well-known page description language, and the image reproducing means 323 executes the reverse order of the combination of the graphics commands. Since the encryption unit is reproduced by the encryption, the encryption and the decryption of the encryption can be easily performed.

When a document is created by the host computer instead of the original, and a part of the document is encrypted and sent by facsimile, conventionally, an application program is started and a one-page image is cut and pasted. On the other hand, in the present embodiment, on the display screen of the display device 13, in contrast to the troublesome work of dividing into two documents, one of which is transmitted without being encrypted and the other of which is transmitted with being encrypted. You can easily specify the area to be encrypted with and select the encryption conversion method.

Further, since the encryption processing of the transmission original can be executed on the personal computer composed of the host computer 12 and the display device 13, the facsimile apparatus main body 11 can be an ordinary facsimile apparatus which cannot be encrypted.

(Second Embodiment) As shown in FIG. 13, the display device 13 is provided in the facsimile device main body 51.
