The execution date and time (print date and time) indicates the date and time when the document was generated.

  FIG. 14 is a flowchart illustrating an example of a processing procedure when the document discarding apparatus 3 discards a document. A user who uses the document disposal apparatus 3 places an IC card with a user ID on the user ID reader 38.

  When a user using the document disposal apparatus 3 places a document to be discarded on the document tray unit 17 and inserts the document into the back side, the insert sensor 18 is turned on immediately before the leading edge of the document hits the first feed roll 20. It becomes a state. At this time, if the QR code (registered trademark) is printed on the document to be discarded, the document is inserted so that the printed surface of the QR code (registered trademark) is the uppermost surface.

  At that time, the document disposal control unit 36 continuously monitors the signal (on / off state) of the insert sensor 18 under the standby state of the document disposal apparatus 3 (S12), and inserts the document by inserting the document by the user described above. When the sensor 18 is turned on (S12-Yes), a barcode reading instruction is given to the barcode reader 19, and a user ID reading instruction is given to the user ID reading device 38.

  Then, in accordance with this reading instruction, the barcode reader 19 reads the QR code (registered trademark) printed on the document (S13), and the user ID reading device 38 reads the user ID (S14).

  Next, the document discard control unit 36 determines whether the QR code (registered trademark) and the user ID have been successfully read (S15).

  Whether or not the QR code (registered trademark) has been successfully read is determined by whether or not the barcode reader 19 has successfully decoded the QR code (registered trademark) printed on the document.

  The barcode reader 19 may fail to read the QR code (registered trademark) when the QR code (registered trademark) printed on the document is significantly soiled or damaged, or when the QR code (registered trademark) is originally registered on the document. (Trademark) is not printed, or the document QR code (registered trademark) is out of the code reading area E (see FIG. 5) due to improper insertion of the document.

  Whether or not the user ID has been successfully read is determined based on whether or not the user ID has been normally decoded by the user ID reading device 38 from the IC card.

  If the QR code (registered trademark) and the user ID are successfully read (S15-Yes), the document discard control unit 36 instructs the feeder drive unit 34 to start the rotation of the first feed roll 20, and the feeder according to this instruction. The drive unit 34 starts to rotate the first feed roll 20 (S16).

  As the first feed roll 20 is driven to rotate, the image scanner is instructed to start image acquisition, and image data is read by the image scanner 21 (S17).

  Then, the QR code (registered trademark), the user ID, the discard attribute (discard date / time), and the image data at the time of discard are transmitted from the network interface 16 to the document management apparatus 4 via the network 5 (S18). For the document specified by the document ID included in the registered trademark, an inquiry is made to the document management apparatus 2 as to whether or not the document is discarded.

  This inquiry creates a discard permission inquiry message specifying the document ID included in the QR code (registered trademark) read by the barcode reader 19, and this inquiry message is sent from the network interface 16 via the network 5 to the document management apparatus. This is done by sending to 4. If the QR code (registered trademark) is successfully read, the information stored in the QR code (registered trademark) may be simply displayed on the operation panel 31.

  When a reply message is returned from the document management apparatus 4, the document discard control unit 36 receives the reply message by the network interface 37, and the content of the reply message is an inquiry from the own apparatus (document discard apparatus 3). Then, it is confirmed whether or not a document disposal permission is given (S19).

  If the response message gives permission to discard the document (S19-Yes), a disposal permission guidance (guidance message) prepared in advance is displayed on the operation panel 31, and then the stopper drive unit 33 is stopped by the stopper. Is instructed to open the stopper gate 23 (S20).

  At this time, the document disposal control unit 36 instructs the feeder driving unit 34 to start the rotation of the second feed roll 22, and the feeder driving unit 34 starts to rotate the second feed roll 22 in accordance with this instruction (S21). ).

  Thereafter, the document discard control unit 36 instructs the shredder driving unit 35 to start driving, and upon receiving this instruction, the shredder driving unit 35 starts driving the shredder unit 24. Therefore, the document sent by the feed roll 22 is taken in as it is into the shredder unit 24, where it is shredded (discarded) and shredded (S22).

  Further, when the trailing edge of the document passes the sensing position of the path sensor 23 and thereby the path sensor 23 is switched from the on state to the off state, the document discard control unit 36 sets a predetermined timing (for example, after the document) At the timing when the end passes through the second feed roll 22, the stopper drive unit 33 is instructed to return to the stopper, the stopper 20 is returned to the original state (projected state), and the shredder drive unit 35 is instructed to stop driving the shredder unit. Then, the drive of the shredder unit is stopped.

  On the other hand, if the reply message does not give permission to discard the document in step S19 (S19-No), the document discard control unit 36 causes the feeder drive unit 34 to start reverse rotation of the first feed roll 20. The feeder drive unit 34 starts reverse rotation driving of the first feed roll 20 in accordance with this instruction. Then, the document is returned to the paper feed tray 17. Further, a disposal non-permission guidance prepared in advance is displayed on the operation panel 31 (S23). An example of the disposal non-permission guidance is “An error has occurred. Please pull out the document.”

  FIG. 15 is a flowchart illustrating an example of a processing procedure when creating document log information when the document management apparatus 4 discards a document.

  The document management apparatus 4 receives the QR code (registered trademark), the image data at the time of discard, the user ID (discarder), and the discard attribute (discard date and time) (S25).

  The document management apparatus 4 decodes the QR code (registered trademark) into a document ID by the barcode analysis unit 41 (S26), and these document ID, image data, user ID (discarder), discard attribute (discard date, etc.) ) Is stored in the database unit 45 by the document management control unit 46 and registered as log information in the document management table.

  Then, based on the acquired document ID, it is determined whether or not the document at the time of printing and the document at the time of discard are the same. That is, the printing image data is searched from the acquired document ID, and the printing image data is extracted (S27).

  Next, the extracted image data at the time of printing is compared with the received image data at the time of discard (S28).

  The difference between the printing image data and the discarding image data, that is, the difference is calculated, the difference is used as the numerator, and the printing image data is used as the denominator to calculate the ratio of the difference (referred to as the difference ratio). (S29).

  It is determined whether or not the difference ratio is 10% or less (S30), and if the difference ratio is 10% or less (S30-Yes), as shown in FIG. And stored in the database unit 45 and registered as log information in the document management table (S31). As shown in FIG. 17A, the document determined in this way is considered to be a document 50a at the time of printing in which there was no illegal action.

  Thereafter, a discard permission is transmitted as a reply message to the document discard apparatus 3 via the network interface 47 (S32).

  When it is determined in step S30 that the difference ratio is not 10% or less (S30-No), it is determined whether the difference ratio is 50% or less (S33).

  If it is determined that the difference ratio is 50% or less (S33-Yes), it is treated as indeterminate, and the administrator's email address is searched and extracted from the administrator ID (S34). The document ID, the printing image data, and the discarding image data are transmitted (that is, to the administrator) (S35), and a confirmation request is made.

  Then, as shown in FIG. 16B, the administrator confirmation is in progress and the data is stored in the database unit 45 and registered as log information in the document management table (S36). As shown in FIG. 17B, the document determined in this way is cut out only the barcode recording portion 30 in which the QR code (registered trademark) of the document at the time of printing is shown, The case of the document 50b pasted on a document having a close content is conceivable.

  The administrator visually confirms the image data at the time of printing and the image data at the time of discard, and appropriately corrects the log information in the document management table.

  Thereafter, a discard rejection is transmitted as an answer message to the document discard apparatus 3 via the network interface 47 (S37).

  If it is determined in step S33 that the difference ratio is not 50% or less (S33-No), as shown in FIG. 16C, the fraudulent act is stored in the database unit 45, and document management is performed. The log information is registered in the table (S38). As shown in FIG. 17C, the document determined in this way is cut out only the barcode recording portion 30 where the QR code (registered trademark) of the document at the time of printing is cut and pasted on a blank document. The case of the attached document 50c can be considered.

  Thereafter, the document discarding apparatus 3 is sent a rejection rejection as a reply message via the network interface 47 (S39).

  FIG. 16 is a diagram illustrating an example of a document management table. As shown in the drawing, the data at the time of disposal is displayed as the subject in the document management table, and the document ID, document name, execution contents, execution date (discard date), user ID (discarder ID), discarder name, discard image ( (Discard image data), manager ID, manager name, presence / absence of fraud (including uncertainties) are registered in association with each other. The execution date (discard date) indicates the date when the document was discarded. Note that management information from printing to discarding may be left for the same document in time series.

  The document management table is created in the database unit 45 as log information. Further, the document management apparatus 4 is configured to be able to browse the document management table, and may be configured to be browseable from the terminal 1. The document ID, the manager ID, and the creator ID are registered with names or names associated with the IDs, and the name and the name are displayed on the document management table at the same time.

  Next, the operation of this embodiment will be described below. For example, the QR code (registered trademark) attached to the document is cut out by acquiring image data of the document to be discarded by the document discarding device 3 by the image scanner 21 and referring to the image data. By pasting (registered trademark) on a different paper (blank) from this document, it will be possible to recognize illegal acts such as leaving a log where the document was discarded and taking the document. .

  The collation determination unit 44 easily determines whether the document at the time of printing and the document at the time of discarding are the same, cuts off the QR code (registered trademark) attached to the document, and this QR code (registered) It becomes easy to recognize the presence or absence of fraudulent acts such as pasting the trademark) on another document different from this document. Further, by being configured to recognize such an illegal act, it has a deterrent function against performing the illegal act and can prevent information leakage to a third party due to the illegal act.

  The document was discarded when there was an illegal act such as cutting the QR code (registered trademark) attached to the document and pasting the QR code (registered trademark) on another document different from this document Since it functions to prevent the storage of information, the accuracy of disposal management is increased.

  Whether the document at the time of printing and the document at the time of disposal are the same or not because the collation determination unit 44 determines by the administrator when the consistency between the document at the time of printing and the document at the time of disposal is low. Judgment is made more accurately.

  Since the collation determination unit 44 is provided in the document management apparatus 4, the collation determination unit 44 of the document management apparatus 4 manages the plurality of document disposal apparatuses 3 when the document management apparatus 4 collectively manages the plurality of document disposal apparatuses 3. Therefore, it is not necessary to provide each document discarding apparatus 3 with a collation determining unit 44, and costs can be reduced.

  Since the collation determination unit 44 collates the image data written in the document, it is possible to more accurately determine whether or not an illegal act has been performed.

  The collation determination unit 44 determines that the image data of the document at the time of printing and the image data of the document at the time of discard are the same or have high consistency based on the difference between the image data. Compared to extracting the same portion of data, the calculation processing load is reduced.

  In the present embodiment, the image data described in the recording medium is used as the related information of the recording medium. However, the present invention is not limited to this. That is, as the related information of the recording medium, other information is applicable as long as it is information used for determining the presence or absence of fraud.

  For example, an identification number embedded in character information (including image information) itself described on a recording medium, an identification number described with transparent toner, and other paper fingerprints can be applied. In any case, it is desirable to make it impossible to recognize in which part of the document the identification number is embedded, and even if it is possible to recognize in which part of the document the identification number is embedded It is desirable that it is practically impossible to extract an identification number, such as using a number for a plurality of locations in a document.
