DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is a block diagram showing the configuration of an image forming apparatus according to the present invention. In the figure, 101 is a scanner that optically reads a document to be copied and obtains image data using a photoelectric conversion element such as a CCD, and 102 is a scanner 1.
The image data from 01 is stored, for example, in the internal RAM of the main body or in an external storage device, and the original data storage unit 103 is commonly used by placing a finger on an operation button (not shown) of the device. It is a fingerprint data recognition unit that recognizes the fingerprint data used for the fingerprint recognition.

Further, 104 is a fingerprint data registration unit for registering fingerprint data, and 105 is a securities data storage unit in which securities data is stored. For example, an external storage device or an internal ROM is used. The accumulation pattern of the securities data storage unit 105 is for recognizing various securities patterns by using, for example, a recognition method used in a bill exchange machine or the like. Further, 106 is an image data determination unit that collates the data in the securities data storage unit 105 with the image data read by the scanner 101,
Reference numeral 107 is a display unit for displaying the status of the apparatus, and 108 is a printer for recording image data on recording paper and outputting it. Further, the control unit 109 that controls the entire apparatus includes a document data storage unit 102, a fingerprint data recognition unit 103, a fingerprint data registration unit 104, a securities data storage unit 105, and an image data determination unit 106. Has been done.

Next, the operation of the image forming apparatus configured as described above will be described. FIG. 2 is a flowchart showing the processing operation according to the present invention. In the figure, when this process is started, the document is first placed at a predetermined position (in this case, A
It is set on the DF document table and the number of copies is input with a ten key (not shown) (S201). Next, the set original is read by the scanner 101 (S202), and the image data of the read original is referred to by the image data stored in the securities data storage unit 105 to be collated by the image data determination unit 106. Execute (S203). At this time, even if the banknote is pasted on plain paper, it is recognized as "the same item".

Further, it is judged whether or not the similarity between the manuscript data and the securities data is 80% or more in the result of the collation processing in step 203 (S204). The percentage value of the similarity is the number of similar points divided by the total number of measurement points. Step 20 above
4, when it is determined that the degree of similarity is not 80% or more, that is, when the document data is not counterfeit data, the read image data is read by the printer 1.
The image forming process is executed according to 08 (S205), and the recording paper is ejected (S206).

If it is determined in step 204 that the degree of similarity is 80% or more, it is further determined whether the degree of similarity is 95% or more (S20).
7). When it is determined in step 207 that the degree of similarity is 95% or more, that is, when the original document to be copied is a forgery target, the copy process is stopped (S208).

When it is determined in step 207 that the degree of similarity is not 95% or more, a warning indicating that only one copy can be made is displayed on the display unit 107 (S209). Next, it is determined whether or not the content of the warning display is OK (S210), and the content of the warning display is O.
When it is determined that the value is not K, it is further determined whether or not copying is prohibited (S211). If it is determined that the copy is not permitted, the original document is received (S2
12).

On the other hand, when it is determined in step 210 that the content of the warning display is OK, the image data of the document and the fingerprint of the copy worker are registered (S21).
3). In order to prevent the misuse of securities by copying, the contents of the document and the fingerprint are stored as backup data in the document data storage unit 102 and the fingerprint data registration unit 104. Further, at this time, the fact that the backup data remains is displayed on the display unit 107 so that there is no inconvenience in inputting. Next, the copy work is started (S214). Then, it is displayed on the display unit 107 that the same copy process cannot be performed within a fixed time (S2).
15). Then, the recording paper on which the image is recorded is discharged, and the original is received (S216).

In the above, the reason why only one copy can be performed is to avoid the abuse of a similar product. In addition, in order to prevent misuse of securities by copying the above, for example, using the backup data of the original contents and fingerprints to prevent the same securities from being copied for three months, use the ticketing number, printing number, etc. You can identify if they are the same.

FIG. 3 is a flow chart showing another processing operation according to the present invention. Note that this processing is the same until the first original is ejected in the above embodiment, and will be described below including that portion. In the figure, when this process is started, first, the document is set at a predetermined position (in this case, the ADF document table), and the number of copies is set by a ten key (not shown).

The image data of the read document is referred to by the image data stored in the securities data storage unit 105, and the image data determination unit 106 executes the collation process (S30).
3). Further, it is judged whether or not the similarity between the manuscript data and the securities data is 80% or more in the result of the collation process (S304). If it is determined that the degree of similarity is not 80% or more, that is, if the document data is not counterfeit data, the read image data is subjected to an image forming process by the printer 108 (S).
305), the recording paper is ejected (S306).

When it is determined in step 304 that the degree of similarity is 80% or more, it is further determined whether the degree of similarity is 95% or more (S30).
7). When it is determined in step 307 that the degree of similarity is 95% or more, that is, when the original document to be copied is a forgery target, the copy process is stopped (S308).

If it is determined in step 307 that the degree of similarity is not 95% or more, a warning is displayed on the display unit 107 that only one copy can be made (S309). Next, it is determined whether or not the content of the warning display is OK (S310), and the content of the warning display is O.
When it is determined that the value is not K, it is further determined whether or not copying is prohibited (S311). If it is determined that the copy is not permitted, the original is received (S3
12).

On the other hand, when it is determined in step 310 that the content of the warning display is OK, the image data of the document and the fingerprint of the copy worker are registered (S31).
3). Then, the copy work is started (S314). Then, it is displayed on the display unit 107 that the same copy process is not possible within a fixed time (S315), the recording paper on which the image is recorded is discharged, and the original is discharged (S31).
6). Next, it is determined whether or not all copy processing has been completed (S317). If it is determined that all copy processing is completed, the standby mode is set (S31).
8). If it is determined in step 317 that all copy processing has not been completed, the ADF

[0025]

As described above, according to the image forming apparatus (Claim 1) of the present invention, the similarity between the securities and the manuscript is judged stepwise by the image data judging means, and the judgment result is obtained. On the basis of the above, the control means prohibits the copying process for the originals having the first similarity or higher, and for the originals having the second similarity or higher and the first similarity or lower lower than the first similarity. Since only one copy is processed and a document having a second similarity or lower is subjected to a normal copy process, it is impossible to recopy a document close to a forgery, and a large amount of copy processing can be prevented. .

According to the image forming apparatus (Claim 2) of the present invention, when the control means attempts to copy the same securities within a predetermined time, the operation of the apparatus is stopped for a certain period of time. It is possible to prevent misuse of the device due to counterfeit copying.

Further, according to the image forming apparatus (Claim 3) of the present invention, the manuscript data is stored in the manuscript data storage means every time a copying operation is performed, and the fingerprint data of the copying operator is recognized. Since the securities are registered in advance, if the securities are copied by some method, the follow-up investigation can be easily performed.
