- An electronic tag is also called an RFID tag or an IC tag, and generally has a configuration in which an IC chip having a memory function and a small antenna are embedded.
- the electronic tag communicates with an external tag reader and Z or writer (hereinafter simply referred to as tag reader Z writer) wirelessly, so it can be identified by reading the identification number ( ID number) attached to each electronic tag. You can read and write data. Since electronic tags are affixed or embedded in objects, various types of electronic tags have been proposed depending on the application.
- Electronic tags are broadly classified into active tags that contain a battery and passive tags that do not contain a battery, depending on the method of generating radio waves.
- the active tag generates the radio wave by itself and sends the information held by the tag to the tag reader Z writer.

In this case, it is necessary for the user to manually operate only the desired electronic tag.
- the method of selecting a desired electronic tag as a processing target using the communication range unique to the tag reader Z writer is not practical because it is fixed by each individual tag reader Z writer.
- Japanese Laid-Open Patent Publication Nos. 2003-8481 and 2003-532203 propose tag readers that adjust the transmission power level for an electronic tag according to the received power level notified of the electronic tag power.

- the tag information buffer 12 stores the position information DT (i) and the information content C (i), and the process proceeds to step S41 described later.
- step S21 it is determined whether or not the position information of the GPS sensor equal force of the sensor processing unit 115 external sensor unit 114 is input. If the determination result is YES, the process proceeds to step S22. .
- step S22 the sensor processing unit 115 obtains the absolute position information D (t) of the electronic device 1 based on the position information and supplies the absolute position information D (t) to the valid tag determination unit 13, and the process proceeds to step S41 described later.
- step S31 by operating switch 172, it is determined whether or not the power of the electronic device 1 as the main item is set to the maximum distance from electronic tag 41 that should communicate without contact. If YES, in step S32, candidates for the maximum distance limit value Vo Ki) from the table unit 141 are displayed on the display unit 16 to prompt the user to select. If the decision result in the step S31 is NO, the process advances to another process that is not directly related to the gist of the present invention.
- step S51 the video processing unit 116 determines whether or not the video information V (i) of the object 40 imaged by the imaging unit 116 has been input. If the determination result is YES, in step S52, , The video information V ′ (i) obtained through the video processing unit 117 is supplied to the display control unit 15, and the process proceeds to step S61 described later.
- step S71 may be performed as indicated by a broken line.
- the sensor processing unit 115 performs distance information D ′ indicating the distance from the electronic device 1 to the electronic tag 41 based on the distance information D (i) input by the ultrasonic sensor isoforce of the distance sensor unit 113. (i) is supplied to the valid tag determination unit 13, and the process proceeds to step S41.
- step S41 If the determination result in step S41 is NO, it is determined that the tag information T, (i) in the tag information buffer 12 is invalid.
- step S42 the valid tag determination unit 13 stores the tag information buffer 12 in the tag information buffer 12.
- Tag information T, (i) is deleted, and the process returns to step S11.
- the determination result of step S41 is NO and the tag information T ′ (i) is not displayed and the object 40 captured by the imaging unit 116 is simply displayed, the video information V (i) is displayed. Since it is supplied to the control unit 15, the video information V (i) is displayed on the display unit 16 in step S62 described later.
- step S41 determines that the tag information T ′ (i) in the tag information buffer 12 is valid.
- step S61 the tag whose display control unit 15 is determined to be valid is determined.
- the combined tag information T ′ (i) and the video information V ′ (i) are combined with the tag information T ′ (i) in the information buffer 12 and the corresponding video information V ′ (i). ) Is supplied to the display unit 16.
- step S62 the display unit 16 displays the video information V ′ (i) corresponding to the tag information T ′ (i) for which the display unit 16 is validated.
- FIG. 8 is a flowchart for explaining the outline of the writing operation of the electronic apparatus 1.
- the user can set the writing mode by operating the operation unit 17 with at least the tag information T, (i) displayed on the display unit 16 in step S62 shown in FIG.
- the processor of the electronic device 1 determines whether or not the write mode is set. If the determination result is YES, the process proceeds to step S82.
- step S 82 the user operates the operation unit 17 to input write information to the processor of the electronic apparatus 1, and the input write information is supplied to the tag information processing unit 112.
- the transmission / reception unit 111 writes the write information obtained from the tag information processing unit 112 into the information content C (i) of the electronic tag 41 by a well-known method, and the process ends.
- the writing mode can be set in a state in which information from the electronic tag that the user is interested in or interested in is displayed on the display unit 16, information on the electronic tag is actively sent to the user tag.
- the operation of selecting only the electronic tag that the user is interested in or interested in is simplified, and the load on the user is reduced accordingly.
- the write information is not particularly limited, and may be, for example, access information indicating that the user has accessed the tag information T (i) of the electronic tag 41, or information such as the user's name.
- information on the number of accesses from the user can be stored in the information content C (i) of the electronic tag 41.
- the object 40 to which the electronic tag 41 is attached is a product
- information on the product reservation from the user may be stored in the information content C (i) of the electronic tag 41. it can.
- information such as date and time can be automatically written in the information content C (i) of the electronic tag 41. It is also possible to allow the user to set the information written to the electronic tag 41.
- information regarding the number of accesses by the user may be automatically written to the electronic tag 41 without the user setting the writing mode.
- this embodiment of the program may be stored in a computer-readable storage medium such as a storage unit of an electronic device.
- the recording medium constituting the computer-readable storage medium is not particularly limited, and a semiconductor storage device, a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, or the like can be used.
- a semiconductor storage device a magnetic recording medium, an optical recording medium, a magneto-optical recording medium, or the like can be used.
- the present invention is applicable to various electronic devices having a tag reader Z writer function for communicating with an electronic tag.
