  The IC circuit unit 150 rectifies the interrogation wave (interrogation signal) received by the tag antenna 151, and a power source unit for accumulating the energy of the interrogation wave rectified by the rectification unit 152 and using it as a drive power source 153, a clock extraction unit 154 that extracts a clock signal from the interrogation wave received by the tag antenna 151 and supplies the clock signal to the control unit 157, a memory unit 155 that can store a predetermined information signal, and the tag antenna 151 A modulation / demodulation unit 156 connected thereto, and the control unit 157 for controlling the operation of the RFID circuit element To via the memory unit 155, the clock extraction unit 154, the modulation / demodulation unit 156, and the like are provided.

  The modulation / demodulation unit 156 demodulates the interrogation wave received from the reader antenna 302 of the RFID tag communication apparatus 300 received by the tag antenna 151, modulates the return signal from the control unit 157, and responds from the tag antenna 151. Transmit as a wave (signal including tag ID).

  The clock extraction unit 154 extracts a clock component from the received signal and supplies a clock corresponding to the frequency of the clock component of the received signal to the control unit 157.

  The control unit 157 interprets the received signal demodulated by the modulation / demodulation unit 156, generates a return signal based on the information signal stored in the memory unit 155, and transmits the return signal to the tag antenna by the modulation / demodulation unit 156. Basic control such as control returned from 151 is executed.

  FIGS. 7A and 7B show an example of the RFID label T created by the tag label producing apparatus 100. FIG.

  As shown in FIG. 7 (b), the RFID label T has a thermal paper 103c and an adhesive layer from the surface side (upper side in FIG. 7 (b)) to the opposite side (lower side in FIG. 7 (b)). 103b and release paper 103a are laminated in this order. The RFID tag circuit element To including the IC circuit unit 150 and the tag antenna 151 is provided on the back side of the thermal paper 103c. In a predetermined print area S on the surface of the thermal paper 103c of the RFID label T, a print R is made as shown in FIG. In this example, the print R of the RFID label T is a character of “12th trial argument document”, and the RFID label T is pasted on, for example, a file in which the 12th trial argument document is bound. The RFID label T is attached to the file by the adhesive layer 103b exposed by removing the release paper 103a.

  Here, one of the greatest features of the present embodiment is that the information acquisition target RFID tag circuit element To corresponds to the information acquisition target RFID tag element To before the information acquisition target RFID tag circuit element To completes the information acquisition target search. In other words, the voice data relating to the search target is reproduced by the speaker 328 and voice guidance is performed. This will be described with reference to FIGS.

  FIG. 8 shows an example (comparative example) in which voice guidance is not performed by reproducing voice data of the RFID label T as described above. This comparative example is an example in which a search completion display is performed when a predetermined document file F is searched by the RFID tag communication apparatus 300A and a search target RFID circuit element To is detected.

  When searching for the document file F using the wireless tag communication device 300A, the operator acquires tag information (including the tag ID) from the wireless tag circuit element To of the wireless label T attached to the document file F. Therefore, communication is started by specifying a tag ID corresponding to the search document file F. Thereafter, the wireless tag communication device 300A is moved along the column of the document file F as shown in FIG. Then, as shown in FIG. 8B, the document file F enters the communication range C of the RFID tag communication device 300A by the above movement, and the tag file is acquired from the RFID circuit element To and detected. Then, an appropriate search completion display is performed on the display unit 313A. The operator looks at the search completion display on the display unit 313A as described above, and visually searches the document file F for the target document file F at the position where the document file F is detected (all document files F). Is attached with a RFID label T on which the document name of the file F is printed). Thereby, the operator finally identifies the document file F.

  As described above, the comparative example has the following problems. That is, during the search of the document file F to be searched, no guidance regarding the search target is performed, so the operator needs to move to the vicinity while searching for the document file F by visual inspection or the like. Further, even after detection, when there are a plurality of files having similar appearances in the vicinity of the document file F as shown in FIG. 8, it is not easy to finally identify the document file F (the target file is It's hard to identify what the file is, even if you know it's found and it's nearby.)

  On the other hand, in the present embodiment, when the RFID tag communication apparatus 300 is moved along the column of the document file F to search for the document file F, as shown in FIG. Before the tag information acquisition from the circuit element To is completed, the audio data related to the search target is reproduced by the speaker 328 and, for example, the voice “Looking for 12th trial argument material” is played. When the RFID tag communication device 300 moves, the RFID circuit element To of the target document file F enters the communication range C of the RFID tag communication device 300, and when the target document file F is detected, the speaker 32 For example, the sound of “The 12th trial argument material has been found” is played.

  If separate voice recording is complicated, a simpler voice preparation method (without considering the unnaturalness of the voice wording) may be used. In other words, a recording of the main body wording representing the search object “This is the 12th Judgment Argument Material”, and a recording of the last wording (descriptive phrase according to the action) “I was looking for” (End wording is prepared in table format, for example). And before completing the tag information acquisition from the RFID tag circuit element To of the document file F, it is reproduced by connecting with “I am looking for the 12th trial argument material” or “I am looking for” If the target document file F is detected, it will be played back by connecting to “It is the 12th Judgment Reasoning Material” and “Found”. It is possible to make a sound saying “It was found in the 12th trial argument document but was found”.

  As described above, the operator visually recognizes the audio data related to the RFID label T, that is, the audio data related to the search target, as a guide before the document file F to be searched for (the 12th trial argument material) is found. The document file F can be searched. As a result, compared to the comparative example without the guide based on the voice data related to the search target at the time of the search, the search target can be reliably recognized before the detection, and the document file F (in this example, the twelfth trial argument document) is final. Identification becomes easy. Details of this content will be described below.

  FIG. 10 is a flowchart showing a control procedure executed by the control circuit 101 of the tag label producing apparatus 100 when producing the RFID label T.

  First, in step S110, the control circuit 101 prints the RFID label T printed from the PC 200 (the control circuit 205) via the communication line NW and the network communication control unit 109, and the tag write data (tag ID and the above-described data). (Including object information such as the name of the file in the example) is received. This step is repeated until print data or the like is received from the PC 200. If received, the process proceeds to the next step S115.

  In step S115, it is determined whether a predetermined recording start operation for starting recording via the microphone 120 has been performed via the operation unit 112 described above. The loop waits until there is a recording start operation. If there is a recording start operation, the determination is satisfied, and the routine goes to Step S120.

  In step S120, the control circuit 101 outputs a control signal to the encoder 122 and the like, and creates voice data with the voice that the operator has blown in from the microphone 120 regarding the RFID label T to be created. The audio data may be information on the contents stored in the IC circuit unit 150 of the RFID circuit element To (in the above example, “This is the 12th Judgment Document”) or such a file name. You may make it read out not only audio | voice but the page content of the file content in detail. That is, the stored contents of the IC circuit unit 150 of the RFID circuit element To are reproduced as audio data. In this case, more detailed and specific information can be given to the operator, and convenience is improved. In addition, as audio data, guide information (such as “located at the left end of the third stage of the cupboard”) for the location of the object to which the RFID label T is attached may be blown. In this case, the operator can be guided directly as a guide for the search direction and the search position. As a result, the search time can be shortened.

  Furthermore, as audio data, visual information of the object to which the RFID label T is attached (color, size, thickness, shape, visible characters, old new appearance, etc. For example, “red file is old, thick file”) “It is written as XX on the back cover”). In this case, when preparing the above-mentioned main body wording and the tailing wording separately, for example, a recording of the main body wording indicating the search target “the 12th trial argument material is red”, and the partial wording for the end The recordings of “I am looking for” and “I have been found” are prepared. And before discovery, it is connected and replayed as “The 12th Judgment Argument Material is Red” and “I am looking for” (ie, “I am looking for the 12th Judgment Argument Material is red”). Then, after the discovery, the “12th Judgment Proceeding Material is red” and “is discovered” is played back (ie, “The 12th Judgment Prosecution Material is red but found”) Is sufficient).

  In step S125, it is determined whether a predetermined recording end operation for ending recording has been performed via the operation unit 112 described above. Until there is a recording end operation, the process returns to step S120 to continue the voice data creation process. If there is a recording end operation, the determination is satisfied, and the routine goes to Step S130.

  In the next step S130, the control circuit 101 performs printing R on a predetermined printing area S of the tag tape 103 by the print head 105 based on the printing data received from the PC 200 in step S110. Further, the access information is generated by the high frequency circuit 102 and transmitted to the RFID circuit element To via the device-side antenna 106, and the object information including the tag ID is written to the IC circuit unit 150.

  In the next step S140, the control circuit 101 determines whether or not the printing / information writing performed in step S130 has been normally completed. For example, the determination as to whether or not the information writing has been completed normally is performed by generating access information corresponding to a confirmation signal for confirming the contents of the IC circuit unit 150 of the RFID circuit element To by the high-frequency circuit 102. Whether or not the writing of the tag ID or the like has been normally completed based on the reply signal transmitted from the RFID tag circuit element To to be written to the RFID circuit element To via the device-side antenna 106. This is done by determining whether or not. If the printing / information writing has not ended normally, the process proceeds to step S150.

  In step S150, the control circuit 101 transmits a control signal to the control circuit 205 of the PC 200 via the network communication control unit 109 and the communication line NW, and displays a message indicating that on the display unit 201 (for example, “printing ends normally”). Error processing ")" which was not completed "or" Tag writing did not end normally "). In addition, corresponding audio data in the database DB may be erased or invalidated. On the other hand, if the printing / information writing has been completed normally, the process proceeds to step S170.

  In step S <b> 160, the control circuit 101 cuts the tag tape 103 with the cutter 107 to create the RFID label T including the RFID circuit element To.

  In the next step S170, the control circuit 101 generates association information in which the tag writing information (tag ID, object information, etc.) of the created RFID label T and the audio data are associated with each other, and the network communication control unit 109 The correspondence information is transmitted to the database DB of the server 400 via the communication line NW (voice data output means), and stored and held. Then, this flow ends.

  In the above, the association information corresponds to the voice related information described in the claims.

  The above flow is not intended to limit the present invention to the procedure shown in the above flow, and the procedure may be added / deleted / changed without departing from the spirit and technical idea of the invention. For example, instead of inputting sound with the microphone 120 in the tag label producing apparatus 100 to create sound data and sending it to the database DB, for example, the sound is inputted with the attached microphone (second sound input means) in the PC 200, and the PC 200 The audio data may be created using the encoder software attached to or taken in and transmitted to the database DB.

  FIG. 11 is a diagram conceptually illustrating an example of the data contents of the database DB after the tag label is created as described above.

  As shown in FIG. 11, in the database DB, the tag ID written in the RFID circuit element To, the article name (in this example, the document name “12th trial argument document”), etc., for the created RFID label T The object information, the voice data (hereinafter referred to as “individual voice data” as appropriate), and the representative voice data as necessary are stored in association with each other.

  Here, the representative voice data refers to a case where a plurality of RFID label T have common voice data (for example, the target belongs to the same group, the target is located in the same group or in the vicinity). Etc.), the (identical) audio data corresponding to the commonality is stored in the RFID circuit elements To of the plurality of RFID labels T.

  As an example, there is audio data recorded separately from the individual audio data in order to express the commonality of each RFID circuit element To. For example, in the above example, the representative voice data related to the material of the twelfth referee was recorded by collectively naming the parts common to the individual sound data as “the twelfth referee”, and the RFID tag label provided in the argument document It can be considered that the individual audio data relating to T is “explanatory material” and the representative audio data relating to supplemental material is “supplemental material”. In addition, the above-mentioned guide information, visual recognition information, etc. may be contained in the individual voice in this case.

  As another example of the representative voice data, extracted data of a common part among the voice data of each RFID circuit element To can be considered. For example, among the materials of the twelfth trial, the individual voice data related to the RFID label T provided in the argument document is “This is the argument document of the twelfth trial”, and the representative voice related to the RFID label T provided in the supplementary document If the data is “supplementary material for the twelfth referee”, the representative audio data may be the “twelfth referee” extracted from the common parts.

  Next, a signal transmitted / received between the RFID tag communication apparatus 300 and the RFID circuit element To and its transmission / reception method will be described by taking an international standard ISO / IEC 18000-6 TypeC protocol as an example. FIG. 12 is a diagram illustrating an example of a time chart of signals transmitted and received between the RFID tag communication apparatus 300 and one RFID tag circuit element To. Note that the signal transmission / reception method shown in FIG. 12 is based on a known slotted random system, and is shown to change in time series from the left to the right. An arrow written between the RFID tag communication device 300 and the RFID circuit element To indicates the signal transmission direction. When the transmission partner is unspecified, it is indicated by a broken line, and the transmission partner is specified. In this case, it is indicated by a solid line.

  In FIG. 12, the RFID tag communication apparatus 300 first transmits a “Select” command to all the RFID tag circuit elements To existing in the communicable area. This “Select” command is a command for designating the conditions of the RFID circuit element To to which the RFID tag communication apparatus 300 performs radio communication thereafter. By limiting the number of elements To, it is possible to increase the efficiency of wireless communication. Then, among the RFID circuit elements To that have received this “Select” command, only the RFID circuit element To that satisfies the designated condition is in a state where it can perform wireless communication thereafter (in the figure, this condition that satisfies this condition). Only one RFID circuit element To is shown).

Next, the wireless tag communication device 300 transmits a “Query” command (reading command) for requesting each tag information (including a tag ID which is identification information) to be transmitted as a response to the same wireless tag group. This “Query” command is a search command for performing a search under a condition in which the number of RFID circuit elements To expected to respond is indefinite. This “Query” command includes a slot number designation value Q designated by a predetermined number (for example, any value from 0 to 15 in this example). When a “Query” command is transmitted from the high frequency circuit 331 via the reader antenna 302, each RFID circuit element To generates random numbers from 0 to 2 ^Q −1 (= 2 to the power of Q−1) by the random number generator 158. Generated and held as a slot count value S.

Then, after the RFID tag communication apparatus 300 transmits the “Query” command via the reader antenna 302, it waits for a response from the RFID circuit element To in a predetermined identification slot. The identification slot is a time frame that is divided by a predetermined period after the first transmission of the “Query” command or the “QueryRep” command described later. The identification slot is normally repeated a predetermined number of times (1 ^Q identification slot of the “Query” command and 2 and subsequent identification slots 2 ^Q −1 of the “QueryRep” command in total 2 ^Q times).

  Then, as shown in the illustrated example, the RFID circuit element To that generates the value 0 as the slot count value S responds with the first identification slot including the “Query” command. At this time, the RFID circuit element To transmits a “RN16” command using, for example, a 16-bit pseudo random number for obtaining permission to transmit tag information to the RFID tag communication apparatus 300 as a response signal.

  Then, the wireless tag communication device 300 that has received the “RN16” command transmits an “Ack” command that permits transmission of tag information with contents corresponding to the “RN16” command. When the RFID circuit element To that has received the “Ack” command determines that the “RN16” command transmitted by the RFID circuit element To itself and the received “Ack” command correspond to each other, The tag information (including the tag ID) is transmitted assuming that the individual RFID tag circuit element To is permitted to transmit the tag information. In this way, transmission / reception of signals in one identification slot is performed.

  Thereafter, in the second and subsequent identification slots, the RFID tag communication apparatus 300 transmits a “QueryRep” command instead of the “Query” command, and another RFID circuit element To ( Wait for a response (not shown). Each RFID circuit element To that has received the “QueryRep” command decrements and holds one value of its own slot count value S. In the identification slot when the slot count value S becomes 0, the “ Transmission / reception of signals including the “RN16” command is performed with the RFID tag communication apparatus 300.

  If there is no corresponding RFID circuit element To in each identification slot (the slot count value S is 0 in the identification slot), no transmission / reception other than the “Query” command or the “QueryRep” command is performed. The identification slot is terminated in a predetermined time frame.

In this way, each RFID circuit element To returns a response signal in a different identification slot, so that the RFID tag communication device 300 does not receive interference via the reader antenna 302, and each RFID tag circuit element To tag. Information can be clearly received and captured. Then, after the “Select” command is transmitted as described above, the first identification slot (one time) starting with the transmission of the “Query” command, and the identification starting with the transmission of the “QueryRep” command after the second identification slot thereafter. A processing unit until a predetermined number of slots are repeated (usually 2 ^Q −1) is referred to as a read trial process (a total of 2 ^Q identification slots are usually). In addition, the number of times the RFID tag communication apparatus 300 performs the reading trial process is referred to as the number of reading attempts.

  FIG. 13 is a flowchart illustrating a control procedure performed by the control circuit 333 of the wireless tag communication device 300 when searching for a search target.

  First, in step S205, the control circuit 333 accesses the database DB of the server 400 via the communication line NW and associates information (tag IDs) regarding all (or a part of) the RFID label T stored in the database DB. , Including object information and audio data). These data are temporarily stored in the RAM 333C included in the control circuit 333.

  In the next step S210, the control circuit 333 outputs a control signal to the display unit 313 to display a list of article names based on the article name information included in the object information in the acquired data. Although a list of article names is displayed here, the present invention is not limited to this, and a list of tag IDs or a list of audio data may be displayed.

  In the next step S215, the control circuit 333 determines whether the processing mode is the single search mode or the multi search mode. When the operator selects the single search mode using the mode selection key 321, the process proceeds to the next step S220 to shift to the single search mode, and the article name list displayed in the above step S210 in the next step S225. It is determined whether or not the operator has selected one article name to be searched using the operation units 326 and 327. This step is repeated until one article is selected, and if selected, the process proceeds to the next step S230.

  In the above description, the operator selects and inputs the article name from the article name list. However, the present invention is not limited to this, and for example, when displaying a list of tag IDs and audio data as described above, A desired tag ID and audio data may be selected and input from the list. In addition, when there are a large number of article name lists, an operator may be able to search by inputting a search condition in order to perform an efficient search.

  In step S230, the control circuit 333 acquires the tag ID and audio data related to the article selected in step S225 (stored in the RAM 333C).

  In the next step S300, single search mode processing (see FIG. 14 described later for the detailed procedure) for searching for one article is performed. Then, this flow ends.

  On the other hand, when the operator selects the multi-search mode using the mode selection key 322 in the above step S215, the process proceeds to the next step S235 to enter the multi-search mode, and in the next step S240, the above step S210 is performed. It is determined whether or not the operator has selected a plurality of articles to be searched using the operation units 326 and 327 from the article name list displayed in step S2. This step is repeated until a plurality of articles are selected. If selected, the process proceeds to the next step S245.

  In step S245, the control circuit 333 obtains tag IDs, audio data (individual audio data) related to the plurality of articles selected in step S240, and the representative audio data as necessary (stored in the RAM 333C). )

  In the next step S400, a multi-search mode process for searching for a plurality of articles (refer to FIG. 15 described later for the detailed procedure) is performed. Then, this flow ends.

  In the above, the procedure of step S205 constitutes voice related information acquisition means described in each claim.

  The flowchart is not intended to limit the present invention to the procedure shown in the flowchart, and the procedure may be added / deleted / changed without departing from the spirit and technical idea of the invention. For example, in the above description, the audio data related to all the tag labels is downloaded from the database DB to the RFID tag communication apparatus 300 in step S205. However, the present invention is not limited to this. Only the information may be downloaded, and the audio data of the RFID label T corresponding to the target object may be acquired from the database DB only after the target object is selected from the tag ID list or the article name list. By doing so, the capacity of the storage means (such as RAM) included in the wireless tag communication device 300 can be reduced.

  FIG. 14 is a flowchart showing a detailed procedure of the single search mode process in step S300.

  First, in step S305, the control circuit 333 outputs the audio data acquired in step S230 to the audio decoder 336, amplifies the decoded audio by the amplifier 338, and outputs the amplified audio to the speaker 328. As a result, audio data relating to the document file F to be searched, for example, “Looking for 12th trial argument material” is reproduced from the speaker 328.

  In the next step S310, the control circuit 333 transmits the “Select” command signal by designating one tag ID acquired in step S230 via the high frequency circuit 331 and the reader antenna 302.

In the next step S320, the control circuit 333 transmits a “Query” command signal in the same manner as the “Select” command signal. At this time, the slot number designation value Q is designated as 2 ⁰ (= 1).

  In the next step S330, the control circuit 333 receives the response signal from the RFID circuit element To for a predetermined time through the reader antenna 302 and the high frequency circuit 331. Thereafter, in step S340, the control circuit 333 determines whether or not the “RN16” command is received as a response signal during the reception time. In this determination, if the “RN16” command is not received, the determination is not satisfied, that is, it is considered that there is no RFID circuit element To responding in the identification slot (here, the first identification slot). Return to S310. On the other hand, when the “RN16” command is received, the determination is satisfied, that is, the RFID circuit element To responding in the identification slot (first identification slot) is considered to exist, and the process proceeds to the next step S350.

  In step S350, the control circuit 333 transmits the “Ack” command having the content corresponding to the pseudo-random number included in the “RN16” command received in step S330 via the high-frequency circuit 331 and the reader antenna 302. Thereafter, in step S360, the control circuit 333 receives tag information from the RFID circuit element To via the reader antenna 302 and the high frequency circuit 331. Thereafter, in step S370, the control circuit 333 determines whether or not the received tag information includes a tag ID (in other words, whether or not the tag ID has been successfully received). If the tag ID is not included, the determination is not satisfied and the process returns to the previous step S310. On the other hand, if the tag ID is included, the determination is satisfied and the routine goes to Step S380.

  In step S380, the control circuit 333 outputs, to the audio decoder 336, audio data in which the audio data started to be reproduced in step S305 has been partially changed (corresponding to the content found), and the audio data decoded thereby. Is amplified by the amplifier 338 and reproduced from the speaker 328. As a result, for example, the audio data “Twelfth trial appeal material was found” is reproduced from the speaker 328. In addition, as described above, when preparing the main unit wording and the tailing wording separately, for example, “It is the 12th Judgment Reasoning Document” or “Found” or “It is on the shelf” They are connected to each other and replayed, such as “The 12th Judgment Appeal Material” “I found”.

  In the above, step S310 to step S360 constitute tag information acquisition means described in each claim. Of these, step S320 constitutes an inquiry signal transmission means, and step S340 constitutes a response signal reception means. Furthermore, step S305 and step S380 constitute a reproduction control means.

  The flowchart is not intended to limit the present invention to the procedure shown in the flowchart, and the procedure may be added / deleted / changed without departing from the spirit and technical idea of the invention. For example, in step S380, in the above, the content of the audio data is changed by the reproduction control means, and the audio of “The 12th trial argument material was found” was reproduced by the audio data with emphasized content. You may make it reproduce | regenerate the audio | voice which calls "It is the twelfth trial argument material", "It is the twelfth trial argument document", and "It is the twelfth trial argument document."

  FIG. 15 is a flowchart showing a detailed procedure of the multi-search mode process in step S400.

  First, in step S405, the control circuit 333 resets the value of the variable N for counting a plurality of tag IDs included in the list to 0.

  In the next step S407, the control circuit 333 outputs the representative audio data acquired in step S245 to the audio decoder 336, and amplifies the decoded audio by the amplifier 338 and outputs it to the speaker 328. As a result, the representative voice common to the plurality of RFID labels T respectively provided on the articles to be searched is reproduced from the speaker 328. Note that it is preferable that the control circuit 333 controls the reproduction of the representative audio data so that it is repeatedly performed at a predetermined time interval until all search targets are found.

  In step S410, the control circuit 333 adds 1 to the value of the variable N, and then in step S415, whether or not the value of the variable N is equal to or less than Nmax (the number of tag IDs to be searched), that is, a plurality of values. It is determined whether or not the search for the last tag ID among the tag IDs has been completed. If the value of the variable N is greater than Nmax, it is considered that the search for all tag IDs has been completed, and the process proceeds to step S460.

  In step S460, the control circuit 333 outputs to the audio decoder 336 the representative audio data in which the representative audio data started to be reproduced in step S407 has been partially changed (contents corresponding to the found data), and is thereby decoded. The voice (for example, as described above, the ending is “all found”) is amplified by the amplifier 338 and reproduced from the speaker 328, and this routine is terminated. On the other hand, when the value of the variable N is equal to or less than Nmax, it is considered that the search processing for all tag IDs is not completed, and the process proceeds to the next step S420.

  In step S420, the control circuit 333 transmits a “Select” command signal by designating the tag ID to the Nth RFID circuit element To via the high frequency circuit 331 and the reader antenna 302.

In the next step S425, the control circuit 333 transmits a “Query” command signal in the same manner as the “Select” command signal. At this time, the slot number designation value Q is designated as 2 ⁰ (= 1).

  In the next step S430, the control circuit 333 receives the response signal from the RFID circuit element To for a predetermined time through the reader antenna 302 and the high frequency circuit 331. Thereafter, in step S435, the control circuit 333 determines whether or not the “RN16” command is received as a response signal during the reception time. In this determination, if the “RN16” command is not received, it is considered that there is no RFID circuit element To responding in the identification slot (here, the first identification slot), and the process returns to step S410. On the other hand, when the “RN16” command is received, it is assumed that there is a RFID circuit element To responding in the identification slot (first identification slot), and the process proceeds to the next step S440.

  In step S440, the control circuit 333 transmits the “Ack” command having the content corresponding to the pseudo-random number included in the “RN16” command received in step S430 via the high-frequency circuit 331 and the reader antenna 302. Thereafter, in step S445, the control circuit 333 receives tag information from the RFID circuit element To via the reader antenna 302 and the high frequency circuit 331. Thereafter, in step S450, the control circuit 333 determines whether or not the tag information is included in the received tag information (in other words, whether or not the tag ID has been successfully received). If the tag ID is not included, the determination is not satisfied and the routine returns to the previous step S410. On the other hand, if the tag ID is included, the determination is satisfied, and the routine goes to Step S455.

  In step S455, the control circuit 333 changes a part of the representative audio data that has been played back in step S407 (a content corresponding to the fact that all files are not found but some files are newly found). The audio data is output to the audio decoder 336, and the decoded audio (for example, “has found out of”) is amplified by the amplifier 338 and reproduced from the speaker 328. In addition, when preparing the main unit wording and the tailing wording separately as described above, in this case, “of” “found” is prepared as the last wording (in the table etc.). You can use it. Thereafter, the process returns to step S407, and the same procedure is repeated from the reproduction of the original representative audio data.

  As described above, the RFID tag communication apparatus 300 includes the audio reproduction button 330 that makes a sound by a manual instruction. In addition to the timing described using the above flow, the audio data can be reproduced at a desired timing desired by the operator. As a result, even if the reproduction of the audio data started when the search for the RFID label T is started (for example, the preset number of repetitions is completed), the audio data is again generated by the manual instruction of the audio reproduction button 330 by the operator. Can be reproduced. Thereby, the convenience can be further improved.

  In the above, step S420 to step S445 constitute tag information acquisition means described in each claim. Of these, step S425 constitutes inquiry signal transmission means, and step S435 constitutes response signal reception means. Further, step S407, step S455, and step S460 constitute a reproduction control means.

  The flowchart is not intended to limit the present invention to the procedure shown in the flowchart, and the procedure may be added / deleted / changed without departing from the spirit and technical idea of the invention.

  As described above, in the RFID tag communication apparatus 300 according to the present embodiment, the wireless tag label T provided on the object to be searched (in this example, the document file F) by wireless communication via the reader antenna 302 is used. Information is read from the tag circuit element To. When a search is performed in the wireless tag communication device 300, the tag ID of the target wireless tag circuit element To is specified, and information is acquired from the specified wireless tag circuit element To via the reader antenna 302.

  At this time, each RFID label T is associated in advance with the tag ID of the RFID circuit element To and the audio data as an association at the time of creation by the tag label producing apparatus 100, and the association information is stored in the database DB of the server 400. Is stored and retained. Then, before completing the information acquisition from the RFID circuit element To at the time of the search (before the search is started in the above example; see step S230 and step S245), the association information is acquired from the database DB. Based on the above, audio data corresponding to the RFID circuit element To to be acquired is acquired, and the corresponding audio (name of the document file F in the above example) is reproduced by the speaker 328. Thus, the operator can search for the document file F while aurally recognizing the RFID label T corresponding to the document file F to be searched before it is found. As a result, it is easy to specify the document file F that is the object, and the convenience can be improved. In particular, since it is a voice, it is easy for an operator to input, and since it is a real voice, it is possible to easily identify who the voice is.

  In the present embodiment, in particular, a playback time bar 315 is provided on the display unit 313 of the RFID tag communication apparatus 300 so that the elapsed time after the start of playback or the remaining time before the end of playback during the playback of audio data by the speaker 328 is displayed. The playback time display is displayed. This makes it easy for the operator to know where the sound being played back corresponds to the entire sound data, or how long the sound will continue. As a result, the convenience can be further improved.

  Further, when the operator selects the multi-search mode and operates and inputs information To identify a plurality of RFID tag circuit elements with the intention of searching for a plurality of document files F, it is used for the plurality of objects. There is a high possibility that there is something in common such as usage and attributes. In this case, the audio data of the corresponding plurality of RFID tag labels T may include a common portion corresponding to the usage or attribute. Correspondingly, in this embodiment, in particular, audio data (individual audio data) related to each RFID label T is not reproduced separately, but representative audio data related to the commonality is reproduced. This makes it possible to reproduce easy-to-understand audio data that matches the operator's intention, and to further improve convenience when searching for a plurality of document files T.

In the present embodiment, particularly, when a response signal is received from the corresponding RFID circuit element To during searching by the RFID tag communication apparatus 300, the audio data of the RFID label T reproduced by the speaker 328 is emphasized. The aspect changes to the content that has been made. As a result, the operator can be audibly surely recognized that the search is successful.

  In the above description, the voice data is stored in the database DB. However, the present invention is not limited to this, and the voice data may be stored in the wireless tag communication device 300. In this case, there is an effect that the audio reproduction process is quickened because it is not necessary to use a network during reproduction.

  In the above description, the case where the RFID label T created by the tag label producing device 300 is used as the RFID tag has been described as an example. However, the present invention is not limited to this. For example, the present invention can be applied to a case where a wireless tag having another aspect, for example, a card-like tag card (IC card) is used, and the same effects as described above can be obtained.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
