  FIG. 5 is a flowchart showing the document discard prompting process according to the first embodiment of the present invention. In step S <b> 501, the server 101 periodically searches the document management DB 102 for a document that has exceeded the destruction period. If there is no document whose destruction time limit has been exceeded, the process is terminated. In step S <b> 502, the server 101 prompts the person responsible for managing the retrieved document whose deadline has been exceeded using a means such as an email. In step S <b> 503, the server 101 stores a history of requesting document destruction in the document management DB 102.

  FIG. 6 is a diagram showing a document in the first embodiment of the present invention. Reference numerals 601 and 602 denote wireless tags. As shown in the figure, the wireless tag may be arranged horizontally as indicated by reference numeral 601 or vertically arranged as indicated by reference numeral 602. The wireless tag is arranged at one end 603a in the longitudinal direction of the document. The range 603 in which the wireless tag is arranged is preferably within 20% of the length 604 in the longitudinal direction of the document.

  FIG. 7 is a flowchart showing a copying process by the copying machine 108 according to the first embodiment of the present invention. In step S701, the control unit of the copier 108 determines whether the copy source wireless tag reader / writer 306 has detected the wireless tag of the copy source document. If detected, the document information is read from the wireless tag, and the process proceeds to step S702. If not detected, the process proceeds to step S708.

  In step S <b> 708, the control unit of the copier 108 displays a prompt or presents a sound so as to present the wireless tag to a display device (not shown) or a sound generation device (not shown). In step S709, the control unit of the copier 108 determines whether the copy source wireless tag reader / writer 306 has detected the wireless tag of the copy source document. If detected, the document information is read from the wireless tag and the process proceeds to step S702. If not detected, the process ends.

  In step S702, the control unit of the copier 108 determines whether the user ID is detected from the wireless tag owned by the user. If detected, the user ID is read and the process proceeds to step S703. If not detected, the process proceeds to step S710.

  In step S710, the control unit of the copier 108 displays a prompt or presents a sound to present the user ID to a display device (not shown) or a sound generation device (not shown). In step S711, the control unit of the copier 108 determines whether the user ID is detected from the wireless tag owned by the user. If detected, the user ID is read and the process proceeds to step S703. If not detected, the process ends.

  In step S703, the control unit of the copier 108 sends the document information and user ID read in steps S701 and S702 to the server 101 to inquire whether copying is possible. The server 101 that has received the information searches the document management DB 102 based on the document information, and whether or not the user has the authority to copy the document and whether the document is permitted to be copied. And the determination result is transmitted to the copying machine 108.

  In step S704, the control unit of the copier 108 determines whether a copy permission signal has been received. If a copy permission signal is received, the process advances to step S705. If not received, in step S712, the control unit of the copier 108 causes the display device (not shown) or the sound generation device (not shown) to display copy rejection or play a sound, and ends the process.

  In step S705, while the copying machine 108 is copying a document, the wireless tag attaching mechanism 303 of the copying machine 108 attaches a wireless tag to the copied document that is a copy. Here, when copying on copy paper having a wireless tag in advance, the wireless tag attaching process can be omitted.

  In step S706, the copy document wireless tag reader / writer 304 of the copying machine 108 writes the document information in the wireless tag of the copied document. Here, the document information to be written in the wireless tag of the copied document is not only the document information item stored in the document management DB 102 but also the material management number assigned to the copy source document and the copy document. It may be configured to write the document identification ID assigned or the document data of the copied document itself.

  In step S <b> 707, the control unit of the copier 108 transmits the document information of the copy source document and the document information of the copied document to the server 101. When the server 101 receives these pieces of document information relating to document copying, it updates the document management DB 102.

  FIG. 8 is a flowchart showing processing of the server 101 at the time of copying processing by the copying machine 108 in the first embodiment of the present invention. In step S <b> 801, the server 101 monitors whether a copy permission inquiry signal has been received from the copy machine 108. If the signal is received from the copier 108, the process proceeds to step S802. When not receiving, it returns to step S801 and continues monitoring. In step S802, the server 101 searches the document management DB 102 based on the received document information.

  In step S803, the server 101 determines whether to permit copying from the search result in step S802. If copying is not permitted, the server 101 transmits a signal indicating that copying is not permitted to the copying machine 108 in step S805, and returns to step S801. In the case of permitting copying, the server 101 transmits a signal to permit copying to the copying machine 108, and proceeds to step S806. In step S806, the server 101 monitors whether copy information has been received from the copy machine. If copy information has been received, the process proceeds to step S807. If not received, the process returns to step S806 to continue monitoring. In step S807, the server 101 stores the copy information in the document management DB 102, and returns to step S108.

  FIG. 9 is a flowchart showing document cutting processing by the shredder 113 in the first embodiment of the present invention. In step S901, the control unit of the shredder 113 monitors whether the paper detection sensor 402 has detected paper. If paper is detected, the process proceeds to step S902. If not detected, the process returns to step S901 to continue monitoring.

  In step S902, it is monitored whether the wireless tag reader / writer 403 has detected a wireless tag. In the present embodiment, the wireless tag is located at the end of the long side direction of the document. Therefore, when a wireless tag of a document to be cut is detected, the wireless tag is cut at a stage where the document is hardly cut when cutting is performed according to the direction. In this case, there is a possibility that a document being cut is taken out to the outside. In order to avoid such a risk, when a wireless tag of a document to be cut is detected, an alarm is sounded so as to cut from the reverse direction in step S904, and the process returns to step S901. Here, when the display unit 408 is provided, an alarm may be sounded, or instead of sounding the alarm, the display unit 408 may be displayed so as to change the document input direction. If the wireless tag reader / writer 403 does not detect the wireless tag, the process advances to step S903. In step S903, the control unit of the shredder 113 opens the shutter 407.

  In step S905, the control unit of the shredder 113 starts rotating the cutter 401 and starts cutting the document. Here, before the cutting of the document is completed, a kill signal may be transmitted to the wireless tag to electronically invalidate the wireless tag. Alternatively, the wireless tag information may be erased by writing clear data.

  Here, the kill signal is a signal that instructs the wireless tag to electronically invalidate the wireless tag itself. An electronically invalidated wireless tag cannot communicate and therefore cannot read or write data. Also, it cannot be reused. On the other hand, the clear signal can be reused without erasing the information of the wireless tag and performing physical destruction.

  Next, in step S906, the control unit of the shredder 113 monitors whether the paper detection sensor 402 detects paper. If no paper to be cut is detected, the shutter is closed in step S909 to end the cutting. If paper is detected, the process proceeds to step S907. In step S907, the control unit of the shredder 113 monitors whether the wireless tag reader / writer 403 has detected a paper wireless tag to be cut. If no wireless tag is detected, the process returns to step S905. If the wireless tag is detected, the document information is read from the wireless tag, and the process proceeds to step S908. When the wireless tag is detected from the document to be cut, since the wireless tag is located at one end in the longitudinal direction of the document to be cut, the cutting of the document is almost completed.

  In step S908, the control unit of the shredder 113 transmits the document information read in step S908 and the discard completion signal to the server 101. Here, the discard completion signal means a signal including document information and information indicating that the document has been discarded. The discard completion information means information including document information and information indicating that the document has been discarded. Next, in step S909, the shutter 407 is closed to end cutting, and the process returns to step S901.

  FIG. 10 is a flowchart showing the processing of the server 101 during the cutting processing by the shredder 113 in the first embodiment of the present invention. In step S1001, the server 101 monitors whether a discard completion signal has been received from the shredder 113. If a discard completion signal is received from the shredder 113, the process proceeds to step S1002. When not receiving, it returns to step S1001 and continues monitoring. In step S <b> 1002, the server 101 stores the data of completion of destruction by the shredder 113 in the document management DB 102, and returns to step S <b> 1001.

  With the configuration described above, in this embodiment, a wireless tag is attached to a document generated by printing or copying, and the wireless tag reader is connected to the printer 103, the copier 108, the shredder 113, and the gate-type wireless tag reader / writer 121.

  FIG. 13 is a flowchart showing a process when a document is input to the discard box 117 according to the second embodiment of the present invention. In step S1301, the control unit of the discard box 117 monitors whether the wireless tag reader / writer 601 detects the wireless tag of the document to be discarded. If a wireless tag is detected, the process proceeds to step S1302. If not detected, the process returns to step S1302 to continue monitoring. In step S1302, the control unit of the discard box 117 controls the wireless tag reader / writer 601 to transmit a kill signal to the wireless tag of the document to be discarded. In step S1303, the control unit of the discard box 117 transmits a discard completion signal to the server 101, and the process returns to step S1301.

  FIG. 14 is a flowchart showing the processing of the server 101 when a document is input to the discard box 117 according to the first embodiment of the present invention. In step S1401, the server 101 monitors whether a discard completion signal has been received from the discard box. If a discard completion signal is received, the process proceeds to step S1402.
