The facsimile apparatus 50 can acquire the area information 40 of the room 4 in which the facsimile apparatus 50 is arranged by reading the area information 40 from the non-contact IC card 3.

  Further, since the area information 40 corresponding to each room 4 is stored in the non-contact IC card 3 simply by bringing the non-contact IC card 3 close to the entrance / exit management device of each room 4, the room 4 currently entering the room 4 in real time. The area information 40 can be stored in the non-contact IC card 3.

  The user 1 leaves the room 4 by holding the contactless IC card 3 over the entrance / exit management device. At this time, the entrance / exit management device deletes the area information 40 stored in the non-contact IC card 3. After deleting the area information 40, the user 1 can leave the room 4 by opening the automatic door 7.

[Document transmission process]
Next, document transmission processing in the present embodiment will be described with reference to FIG. FIG. 9 is a flowchart of the document transmission process.

  The document transmission process is a process of adding predetermined attribute information to a document to be transmitted and transmitting the document from the transmission side facsimile apparatus 50A to the reception side facsimile apparatus 50B.

  In response to the operation of the user 1A, the input unit 21A (for example, a scanner) reads a document, a map, a photograph, and the like, and uses the read content as an image, thereby generating a document to be transmitted. (Step S11).

  After the document is generated, the in-document attribute information generation unit 61 causes the user 1A to operate the input unit 23A (for example, an operation key or the like) to specify the area information 40 or the user information (for example, the user information). "User whose affiliation is the development department") is registered in the attribute information of the document (step S12).

  When the transmission side facsimile apparatus 50A detects that a transmission instruction has been made through the operation of the input unit 23A by the user 1A, the document is transmitted to the reception side facsimile apparatus 50B via the communication unit 28A (step S13). ).

  As a result, the area information 40 and the user information specified by the user 1A are included in the attribute information of the document. Therefore, the facsimile apparatus 50 (for example, the receiving facsimile apparatus 50B) that received the document When the document information is transmitted, the security level value and user information of the area information 40 registered according to the operation of the user 1A can be referred to when the document is transmitted.

[Document reception processing]
Next, document reception processing in the present embodiment will be described with reference to FIG. FIG. 10 is a flowchart of the document reception process.

  The document reception process is a process for determining whether or not to store the document by referring to the attribute information of the received document.

  When the document is transmitted from the transmitting facsimile apparatus 50A to the receiving facsimile apparatus 50B, the receiving facsimile apparatus 50B receives the document via the communication unit 28B (step S21).

  The document area information reading unit 71 reads the document area information 40 registered in the attribute information of the document (step S22).

  The security level comparison unit 72 compares the security level value of the area information 40B, which is the receiving device area information 40 stored in the storage unit 24B, with the security level value of the in-document area information 40, and outputs the comparison result. (Step S23).

  As a result of the security level comparison unit 72 comparing the security level value of the in-document area information 40 with the security level value of the receiving device area information 40, the document reception control unit 73 determines that the security level value of the receiving device area information 40 Is greater than or equal to the security level value of the document area information 40 (step S23; Yes), the document is stored in the storage unit 24B (step S25), and the document reception process is terminated.

  As a result of the security level comparison unit 72 comparing the security level value of the in-document area information 40 with the security level value of the receiving device area information 40, the document reception control unit 73 determines that the security level value of the receiving device area information 40 Is lower than the security level value of the document area information 40 (step S23; No), after discarding the document, a log indicating that the document has been discarded is transmitted to the transmitting facsimile machine 50A (step S24). .

  As described above, when the document is discarded, the log is transmitted to the transmission side facsimile apparatus 50A so that the transmission side facsimile apparatus 50A displays the log information on the display unit 21A after receiving the log information. be able to. Accordingly, the user 1A can confirm that the document transmission has failed by referring to the log information displayed on the display unit 21A. As described above, after the log is transmitted, the document reception process is terminated.

  According to this, the area information 40 is stored in the receiving facsimile machine 50B. When receiving facsimile apparatus 50B receives a document from transmitting facsimile apparatus 50A, document area information reading unit 71 reads document area information 40. The security level comparison unit 72 compares the security level value of the receiving device area information 40 with the security level value of the area information 40 registered in the attribute information of the document, and outputs a comparison result. The document reception control unit 73 determines whether or not to store the document based on the comparison result. Specifically, the receiving side facsimile apparatus 50B has a case where the security level value of the area information 40 stored in the receiving side facsimile apparatus 50B is lower than the security level value of the area information 40 registered as attribute information of the document. The document reception control unit 73 discards the document.

  Thus, for example, when the security level value of the document area information 40 is “5”, the security level value of the area information 40B that is the receiving device area information 40 is “5”, and the security level of the receiving device area information 40 is Since the value is equal to or greater than the security level value of the document area information 40, the document is stored in the storage unit 24B.

  On the other hand, when the security level value of the document area information 40 is “6”, the security level value of the area information 40B as the receiving device area information 40 is “5”, and the security level value of the receiving device area information 40 is “5”. Since the document area information 40 is less than the security level value, the document is discarded without storing the document in the storage unit 24B.

  As described above, even when the user 1A mistakenly designates the destination facsimile number, the facsimile device 50 (for example, the receiving facsimile device 50B) that receives the document can save the document in the document attribute information. By comparing the security level value of the area information 40 with the security level value of the receiving device area information 40 stored in the storage unit 24B of the receiving facsimile device 50B, a security level value equal to or higher than the security level value of the in-document area information 40 is obtained. Other than the facsimile apparatus 50 having the receiving apparatus area information 40 including the security level value, the document is not stored after the document is received.

  That is, when a document is erroneously transmitted by the operation of the user 1A, the possibility that the document is illegally used can be reduced.

  Further, for example, the receiving side facsimile apparatus 50B is installed in the room 4 where the security level value of the area information 40 is “6”, but the security level value is changed as in the present embodiment without changing the facsimile number. Is moved to the room 4B corresponding to the area information 40B having “5”. In this case, in the conventional facsimile apparatus, when the transmitting facsimile apparatus transmits a document to the receiving facsimile apparatus in a room having a lower security level value than before the movement, the receiving facsimile apparatus The document is stored without making a determination regarding the security level value. As a result, the receiving facsimile apparatus can display information about the document or print the document in accordance with the user's operation.

  This means that the user who operated the transmission side facsimile machine can output documents such as display and printing regardless of whether it is installed in the room where the reception side facsimile machine is installed. Will be made. In other words, if the receiving facsimile machine is moved to a room with a lower security level than before the movement, the user does not have the right to enter the room before the movement, but the user having the right to enter the room after the movement has Since it becomes possible to display or print the document using the receiving facsimile machine, the possibility of unauthorized use of the contents of the document increases.

  On the other hand, in this embodiment, in the transmitting facsimile machine 50A, the document area information 40 is registered in the document attribute information for the document to be transmitted. Whether the receiving-side facsimile apparatus 50B stores the document in the receiving-side facsimile apparatus 50B based on the comparison result between the security level value of the in-document area information 40 and the security level value of the receiving apparatus area information 40. judge. As a result, the user 1A who operates the transmission side facsimile apparatus 50A receives the reception side in the room 4 that is less than the security level value of the area information 40 corresponding to the room 4 in which the reception side facsimile apparatus 50B is assumed to be installed. When the facsimile machine 50B is installed, the document reception control unit 73 of the receiving facsimile machine 50B discards the document to be transmitted.

  As described above, when the transmission side facsimile apparatus 50B is transmitted to the reception side facsimile apparatus 50B installed in the room 4 having a security level lower than the value specified by the user 1A of the transmission side facsimile apparatus 50A, the document is discarded. By changing the installation room 4 of 50B, the possibility that the contents of the document are illegally used by an unintended user 1 can be reduced.

  In this embodiment, the document reception control unit 73 determines that the security level value of the receiving device area information 40 is less than the security level value of the in-document area information 40 as a result of comparison by the security level comparison unit 72. Although the case of discarding the received document has been described, the present invention is not limited to this. For example, when the security level value of the receiving device area information 40 is equal to or lower than the security level value of the in-document area information 40, the document reception control unit 73 compares the received document with the security level comparison unit 72 such as discarding the received document. The received document may be discarded based on various conditions using the result.

[Document availability judgment process]
Next, the document availability determination process in the present embodiment will be described with reference to FIG. FIG. 11 is a flowchart of the document availability determination process.

  The document availability determination process includes the security level value of the area information 40 stored in the contactless IC card 3B and the security level value of the area information 40 registered as the attribute information of the document stored in the storage unit 24B. And the user information stored in the contactless IC card 3B possessed by the user 1B who operates the receiving side facsimile apparatus 50B is registered in the document attribute information. This is a process of determining whether or not the document can be used based on a determination result of whether or not it is included in the possible person information.

  Here, the use of the document means that the document stored in the storage unit 24 is displayed on the display unit 21 or printed via the printing unit 26.

  Here, as a specific example, a case where a document stored in the storage unit 24B of the receiving facsimile machine 50B is used will be described.

  The user 1B enters the room 4B by the above entry process. Thereby, the area information 40B is memorize | stored in the memory | storage part 90 of the non-contact IC card 3B which the user 1B has. In addition, the storage unit 90 of the non-contact IC card 3B stores user information related to the user 1B in advance.

  Next, when the user 1B brings the non-contact IC card 3B close to the IC card reader 9B, the information reading unit 25B in the IC card of the receiving side facsimile apparatus 50B is stored in the storage unit 90 of the non-contact IC card 3B. The area information 40B and user information, which are area information (hereinafter also referred to as IC card area information) 40, are read (step S31).

  Next, the stored document area information reading unit 77 reads the document area information 40 registered in the attribute information of the document stored in the storage device 24 of the facsimile machine 50B, and the in-document user information reading unit. 74 reads the user information registered in the attribute information of the document (step S32).

  Next, the security level comparison unit 72 compares the security level value of the IC card area information 40 with the security level value of the document area information 40, and outputs the comparison result (step S33).

  As a result of comparing the security level value of the IC card area information 40 with the security level value of the document area information 40, the document usage control unit 76 determines that the security level value of the IC card area information 40 is the document area information. If it is lower than the security level value of 40 (step S33; No), use prohibition processing for the document is performed (step S35).

  Here, the use prohibition process of the document means a process of hiding information related to the document on the display unit 21B, a process of prohibiting the printing of the document via the printing unit 26, and the like.

  As described above, as a result of comparing the security level value of the IC card area information 40 with the security level value of the document area information 40, the security level value of the document area information 40 registered in the attribute information of the document is obtained. If it is larger, the use process of the document is prohibited.

  For example, after the receiving side facsimile apparatus 50B is installed in the room 4 corresponding to the area information 40 with the security level value “6”, the receiving side facsimile apparatus 50B includes the area information 40 with the security level value “6” in the attribute information. Is stored in the room 4B in a state where the registered document is stored.

  Under such circumstances, when the user 1B brings the non-contact IC card 3B close to the IC card reader 9B, the IC card information reading unit 25B stores the area information 40 stored in the storage 90 of the non-contact IC card 3B. The area information 40B having the security level value “5” is read.

  Then, the security level comparison unit 72 compares the security level value of the IC card area information 40 with the security level value of the document area information 40 of the document stored in the receiving facsimile machine 50B.

  In this case, since the security level value of the IC card area information 40 is “5” and the security level value of the document area information 40 is “6”, the document use control unit 76 performs the use prohibition process for the document. I do.

  Accordingly, the facsimile apparatus 50 moves to the room 4 in which the area information 40 having a security level value lower than the security level value of the area information 40 registered in the document attribute information stored in the facsimile apparatus 50 is defined. In this case, by prohibiting the use of the document, the user is not authorized to enter the room 4 in which the facsimile apparatus 50 before moving is installed, but the room in which the facsimile apparatus 50 after moving is installed. The use of the document by the user 1 who has the authority to enter the room 4 can be prohibited.

  That is, it is possible to reduce the possibility that the contents of the document are illegally used by an unintended user 1.

  As a result of comparing the security level value of the IC card area information 40 with the security level value of the document area information 40, the security level value of the IC card area information 40 is greater than or equal to the security level value of the document area information 40. If there is (step S33; Yes), the user information determination unit 75 refers to the user information registered as the attribute information of the document and the user information stored in the storage unit 90 of the non-contact IC card 3. Then, it is determined whether or not the user information is included by determining whether or not the user information is included in the user information (step S34).

  When it is determined that the user information determination unit 75 is not usable (step S34; No), the document use control unit 76 performs use prohibition processing for the document (step S35).

  In this way, by determining whether or not the document can be used for each user, whether or not the document can be used is determined only by the comparison result between the security level value of the IC card area information 40 and the security level value of the document area information 40. Document management with higher accuracy than in the case of determination can be realized.

  When the user information determination unit 75 determines that the document is usable, the document use control unit 76 permits the display unit 21B to display information related to the document or to print the document. (Step S34; Yes).

  If the user information determination unit 75 determines that the document can be used, the receiving facsimile device 50B displays information on the document on the display unit 21 or prints the document (step S36). The document usage control unit 76 uses the facsimile device 50 (for example, the transmission side facsimile device 50A) that has transmitted the document to use contents (for example, “print”, “display”, etc.) and information about the user 1 who has operated the document. Log information having (for example, a user ID) is transmitted (step S37).

  According to this, after receiving the log information, the transmitting-side facsimile apparatus 50A can display the log information on the display unit 21A. Therefore, the user 1A can confirm which user 1 has used the transmitted document by referring to the log information displayed on the display unit 21A. Incidentally, in the case of a conventional facsimile apparatus, it is unclear which user used the document after transmitting the document. Therefore, it is possible to realize a document management system that is more useful than conventional methods for managing documents.

  In the present embodiment, as a result of the comparison by the security level comparison unit 72, the document usage control unit 76 determines that the security level value of the IC card area information 40 is less than the security level value included in the document area information 40. In this case, the use of the document is prohibited, but the present invention is not limited to this. For example, when the security level value of the IC card area information 40 is equal to or lower than the security level value of the document area information 40, the document use control unit 76 compares the security level by the security level comparison unit 72, for example, prohibiting the use of the document. You may make it prohibit use of a document based on various conditions using the result.

  In the present embodiment, the non-contact IC card 3 is used. However, the present invention is not limited to this, and a mobile phone equipped with an information storage medium may be used. That is, in the present invention, any portable storage medium can be applied as long as it can be used as access control for entering and leaving the room.

  Furthermore, in this embodiment, the case where the transmitting side facsimile apparatus 50A is used as the transmitting apparatus and the receiving side facsimile apparatus 50B is used as the receiving apparatus has been described. However, the present invention is not limited to this, and various other types are possible. It can be applied to devices and equipment. For example, a personal computer may be used as the transmission device and a printer may be used as the reception device.
