  Here, a series of operation processes executed to perform file search will be described. When a predetermined operation is performed using the input device 31 while the file management application is activated, a file search screen 71 is displayed on the display 33 (see FIG. 3). In the present embodiment, the file information is composed of five information items including a file name, a file classification, a file creation date, a file creator, and an arrangement position of the file F (in which book shelf B the file F is arranged). In the file search screen 71, the user can input search data as a search condition for searching for a file in association with each item. In this case, it is sufficient for the user to input search data for at least one information item, and it is not necessary to input search data for all information items.

  Note that item identification information for identifying which information item the data belongs to is attached to the data of each information item stored in the memory unit 41 (file information storage area) of the wireless IC tag 11. The data can be identified for each information item.

  When the data processing device 4 (the control unit 62) acquires the search data based on the input of the search data by the user, the search condition is met from all the files stored in the entire book shelf B based on the acquired search data. A file search process for searching for a specific file to be started is started. As shown in FIG. 4, in the file search process, first, the control unit 62 of the data processing device 4 selects from the all wireless IC tags 11 the information item to which the acquired search data belongs, that is, the data corresponding to the search information item (search Information transmission command for reading data (file name data) corresponding to the target data) and file name is created (S11), and the created information transmission command is transmitted to all wireless ICs via the wireless communication terminals 3 It transmits to the tag 11 (S12). Then, each wireless IC tag 11 that has received the information transmission command transmits search target data and file name data to the data processing device 4 via the wireless communication terminal 3 (S13). At this time, each wireless IC tag 11 transmits its tag identification information together with search target data and file name data.

  The data transmitted from the wireless IC tag 11 is associated with search target data, file name data, and tag identification information for each wireless IC tag 11, and is temporarily stored in the hard disk 66, and used for subsequent data acquisition. It is done. The data processing device 4 determines whether the transmitted and stored search target data satisfies the search condition (whether it matches the acquired search data) and associates it with the search target data determined to be applicable The obtained file name data is obtained (from the hard disk 66). After determining all the search target data received from all the wireless IC tags 11 and obtaining the file name data (S14), the data processing device 4 displays a search result display screen 81 showing the result of the file search on the display 33. It is displayed (S15).

  As shown in FIG. 5A, the search result display screen 81 includes a search condition, the number of hits corresponding to the search condition, and file name data acquired when it is determined that the search target data matches the search condition. That is, the file name (list) based on the file name data stored in the same wireless IC tag 11 as the search target data determined to satisfy the search condition is displayed. On the search result display screen 81, file names are displayed for each predetermined number, and other file names that do not fit in the predetermined number are displayed as a list by clicking the next page display button 82. Instead of displaying a list of file names corresponding to the search condition for each predetermined number, the file names may be scrolled. Further, the search result display screen 81 is provided with a condition narrowing button 83 for further narrowing down the search conditions and a return button 84 for returning to the file search screen 71.

  The file name displayed on the search result display screen 81 can be selected by the user. When the user selects a file name on the search result display screen 81, the file information of the file having the selected file name is displayed in detail. (See FIG. 5 (b)).

  As shown in FIG. 6, when the user selects a file name, the data processing device 4 acquires file name data corresponding to this based on the user selection result, and further associates with the acquired file name data. Tag identification information is acquired (S21). Subsequently, based on the acquired tag identification information, the data processing device 4 can respond only to the wireless IC tag 11 having the tag identification information (hereinafter referred to as a designated IC tag), that is, only the designated IC tag is targeted. The created file information transmission command is created (S22), and the created file information transmission command is transmitted (via the wireless communication terminal 3) (S23). When the designated IC tag receives the file information transmission command, this is used as a trigger to transmit the data of all information items stored as file information to the data processing device 4 (S24). Then, the data processing device 4 displays the detailed information display screen 91 and displays the contents of all the information items on the display 33 based on the data of all the information items received from the designated IC tag (S25).

  As described above, in the present embodiment, by selecting the file name displayed on the display 33 by the file search, the specific file F is specified, and the file information of the file F is pasted on the file F. The data can be read from the wireless IC tag 11 and displayed on the display 33 of the data processing device 4. Therefore, the user can browse the file information of the file corresponding to the search condition from the display 33 of the data processing device 4 without going directly to the file, and the convenience of the user can be improved.

  The hard disk 66 stores in advance terminal position information that associates each bookshelf B with each wireless communication terminal 3 arranged on the shelf. Therefore, when the search information item includes the arrangement position of the file F, the file search is performed by using only the specific wireless communication terminal 3 based on the terminal position information. The number of data handled by the data processing device 4 can be reduced as compared with the configuration using the file search, and the file search process can be performed efficiently.

  Further, since the position information of each wireless communication terminal 3 can be grasped based on the terminal position information, unique terminal identification information possessed by each wireless communication terminal 3 can be used as the file placement position data. In this case, when the wireless communication terminal 3 sends the data from the wireless IC tag 11 to the data processing device 4, the terminal identification information of the wireless communication terminal 3 may be attached and transmitted. Thereby, it is not necessary to store the file arrangement position data on the wireless IC tag 11 side, and the file arrangement position can be grasped in real time.

  By the way, the file management system 1 of the present embodiment can browse file information from the display 33 of the data processing device 4. On the other hand, it is natural that the user goes directly to the file searched by the file search. Conceivable. In this case, in the file management system 1, the desired file F can be easily found by causing the LED 15 of the IC-tagged label 2 attached to the file to be searched to emit light. .

  When a predetermined operation is performed from the search result display screen 81, an LED drive setting screen 101 for performing settings related to driving of the LED 15 is displayed. Then, the data processing device 4 transmits a driving command for the LED 15 to the IC tag 11 based on the setting on the LED driving setting screen 101.

  As shown in FIG. 7, the LED drive setting screen 101 has a drive setting unit 102 for setting whether to drive the LED 15, that is, whether to cause the LED 15 to emit light, and a timing for setting the drive timing (light emission timing) of the LED 15. A setting unit 103, a time setting unit 104 for setting the driving time (light emission time) of the LED 15, and an OK button 105 for confirming the setting are provided. The drive setting unit 102 is provided with a check box corresponding to each file name displayed on the search result display screen 81, and individually determines whether or not to drive the LED 15 attached to the file having the file name. Can be set to. The timing setting unit 103 sets at which timing the LED 15 is to be driven. When a time is input by numerical input or selection from an option, the input time elapses after the setting is confirmed. After waiting, the driving of the LED 15 is started. Similarly, the time setting unit 104 sets the driving time of the LED 15 by numerical value input or selection from options.

  As shown in FIG. 8, when the setting on the LED drive setting screen 101 is completed, the data processing device 4 acquires (from the hard disk 66) tag identification information corresponding to the file name for which the LED 15 is set to be driven (S31). To do. Then, the wireless IC tag 11 having the acquired tag identification information is designated, and a drive command for the LED 15 based on the setting is created (S32), and the created drive command is transmitted (via the wireless communication terminal 3) ( S33). The wireless IC tag 11 designated by the data processing device 4 drives the LED 15 based on this drive command (S34).

  Thereby, only the LED 15 of the label 2 with the IC tag attached to the file F of the search object desired by the user emits light. Accordingly, the user uses the light emission of the LED 15 as an index together with the file arrangement position information obtained from the file arrangement position data, so that any one of the plurality of files F stored in the bookshelf B is desired. It is possible to easily determine whether it is F, and it is possible to quickly find a desired file F from a plurality of files F.

  The wireless IC tag 11 can perform control relating to the drive timing of the LED 15 and the drive time of the LED 15 based on the drive command, but in the present embodiment, the drive control of the wireless communication terminal 3 is performed. (Ie, by controlling the supply timing and supply time of the radio wave to the wireless IC tag 11 by the wireless communication terminal 3).

  Next, a file management system according to the second embodiment will be described. Since the file management system of the second embodiment is configured in substantially the same manner as in the first embodiment, only the different parts will be described here. Although the tag identification information is stored in the wireless IC tag 11 (memory unit 41) of the label 2 with IC tag constituting the file management system 1 of the present embodiment, the file information is not stored. On the other hand, in the data processing device 4 (hard disk 66), a file management database (not shown) in which the file information of the file F and the tag identification information of the wireless IC tag 11 attached to the file F are associated in advance is stored. Has been.

  In the file search, when a user inputs data from the file search screen 71 and the data processing device 4 acquires search data (search conditions) in the same manner as in the first embodiment, a series of file search processes starts. Is done.

  As shown in FIG. 9A, in the file search process, first, the file management database is searched based on the search data. Specifically, data corresponding to the search condition is read from the data belonging to the search information item, and subsequently, file name data associated with the read data is read (S41). Then, based on the read file name data, the file name (list) is displayed on the search result display screen 81 to obtain the file search result (S41).

  When the driving of the LED 15 is set from the LED driving setting screen 101 similar to that in the first embodiment, the data processing device 4 searches the file management database again as shown in FIG. 9B. Then, the tag identification information corresponding to the file name for which the LED 15 is set to be driven is read (S51). Next, based on the search result and the setting result on the LED drive setting screen 101, a drive command for the LED 15 that can be responded only by the wireless IC tag 11 storing the read tag identification information is created (S52). The created drive command is transmitted (via terminal 3) (S53). As a result, the wireless IC tag 11 that stores the read tag identification information receives the drive command and drives the LED 15 to emit light (S54).

  As described above, in the file management system according to the second embodiment, the search is performed using the file management database stored in advance in the data processing device 48 (hard disk 66), so that the time required for file search is reduced. It is possible. In the file management system 1 according to the second embodiment, when the system is activated, first, data (tag identification information) is transmitted and received between the data processing device 4 and all the wireless IC tags 11 to manage the file. The difference between the tag identification information of the wireless IC tag 11 stored in the database and the received tag identification information of the wireless IC tag 11 is acquired. As a result, the file F stored in each bookshelf B when the file management system 1 is started, in other words, the file F that is stored in the file management database but does not exist in the bookshelf B due to file take-out, etc. It is possible to grasp.

  Next, a file management system according to the third embodiment will be described. The file management system according to the third embodiment is also configured in substantially the same manner as the first embodiment except that some of the operation processes in the file search are different. Therefore, only the file search will be described.

  Also in the file search of the present embodiment, data input from the file search screen 71 and acquisition of search data (search conditions) based on this are performed in the same manner as in the first embodiment, and then the file search process is started. The

  As shown in FIG. 10, in the file search process, first, based on the acquired search data, it is searched whether data corresponding to the search data is stored in the wireless IC tag 11 (file information storage area). In addition, when the corresponding data exists, the data processing device 4 is instructed to return the stored file name data together with the tag identification information of the wireless IC tag 11 to the data processing device 4 (via the wireless communication terminal 3). A search / reply command is created (S61). Then, the created search / reply command is transmitted to all the wireless IC tags 11 via the (a plurality of) wireless communication terminals 3 (S62).

  Thus, with the reception of the search / reply command as a trigger, the wireless IC tag 11 performs a search as to whether or not the data corresponding to the search data is stored in the file information storage area (S63). ) When it is determined by search that the corresponding data exists, the data processing device 4 returns (transmits) its own tag identification information and stored file name data (S64).

  The data processing device 4 associates the tag identification information and the file name data returned from the wireless IC tag 11 with each other and temporarily stores them in the hard disk 66, and searches the file name (list) based on the received file name data. The result is displayed on the result display screen 81 and set as a file search result (S65).

  As described above, in the file management system 1 of the third embodiment, it is determined whether the wireless IC tag 11 has data corresponding to the search condition. Since only the search result of the tag 11 is received, the number of data handled by the data processing device 4 can be reduced.

  Hereinafter, the driving and setting of the LED 15 are the same as those in the first embodiment, and the file name data is selected based on the user setting via the search result display screen 81 and associated with the selected file name data. The tag identification information is read from the hard disk 66. Then, the data processing device 4 creates and transmits a drive command for the LED 15 specifying the wireless IC tag 11 having the read tag identification information.

  As described above, in the file management system to which the present invention is applied, since the signal transmission means controlled by the wireless IC tag is provided on the label with the IC tag, a desired file can be easily selected from a plurality of files. It is possible to search and improve user convenience.

  Needless to say, the apparatus configuration and control configuration of the file management system can be appropriately changed without departing from the gist of the present invention, regardless of the embodiment described above. For example, each wireless communication terminal 3 is provided with an LED, and the LED of the wireless communication terminal 3 that communicates with the IC tag 11 that performs drive control of the LED 15 is made to emit light according to the light emission driving of the LED 15 of the wireless IC tag 11.
