  Further, as shown in FIG. 2, the antenna 48 of the antenna unit 46 has the direction (extending direction) of the antenna 48 intersecting (orthogonal in the present embodiment) between the upstream side and the downstream side in the transport direction. Specifically, the antenna unit 46 disposed on the upstream side in the transport direction is referred to as an antenna unit 46A (antenna 48A, radio wave conversion control unit 50A), and the antenna unit 46 disposed on the downstream side in the transport direction is the antenna unit 46B ( In the case of the antenna 48B and the radio wave conversion control unit 50B), the antenna 48A extends along the transport direction, and the antenna 48B extends in a direction orthogonal to the transport direction. For this reason, the vibration direction of the radio wave (polarized wave) transmitted from the antenna 48A and the vibration direction of the radio wave (polarized wave) transmitted from the antenna 48B are 90 degrees out of phase. That is, even if the arrangement interval between the antenna 48A and the antenna 48B is narrowed, interference between radio waves is suppressed to the minimum. The antenna 48A is disposed so as to overlap with the antenna 16 of the first tag 12 described later in plan view when the tag mounting sheet 10 described later moves on the information writing unit 42.

That is, when writing information to the first tag 12 and the second tag 22 of the tag attachment sheet 10, the controller 58 temporarily stops the conveyance of the tag attachment sheet 10, and after completion of the writing, conveys the tag attachment sheet 10. The drive motor 74 can be controlled to resume.

<Tag mounting sheet>
FIGS. 3A and 3B show the tag attachment sheet 10 on which information is written to the first tag 12 and the second tag 22 by the tag information writing device 40. The tag attachment sheet 10 includes a mount 10A as an example of a sheet, and a plurality of label pieces 11 that are detachably attached to the mount 10A and in which the first tag 12 or the second tag 22 is enclosed. In this embodiment, the mount 10A of the tag attachment sheet 10 is A4 size, and the label pieces 11 are pasted in 5 rows and 2 columns (the longitudinal direction is the row direction Y and the short direction is the column direction X). (A total of 10 label pieces 11). Further, the label piece 11 has an image formed (printable) on the front surface, and adhesive is attached to the back surface so that it can be attached to a management article such as a book when peeled off from the mount 10A. ing.

  A first tag 12 as an RFID tag is sealed inside the odd-numbered label pieces 11 in the Y direction, and a second tag 22 as an RFID tag is sealed inside the even-numbered label pieces 11. . In other words, the first tag 12 and the second tag 22 are attached to the mount 10A via the label piece 11. The first tag 12 includes an IC chip 14 on which a nonvolatile memory (hereinafter simply referred to as “memory”) for storing electronic information is mounted, and a pole-shaped antenna 16 electrically connected to the IC chip 14. It is configured. As the memory, an electrically rewritable memory is used, but a memory that can be written only for the first time may be used according to the application. The antenna 16 extends along the X direction on both sides of the IC chip 14. The second tag 22 includes an IC chip 24 on which a memory for storing electronic information is mounted, and a pole-shaped antenna 26 that is electrically connected to the IC chip 24. As the memory, an electrically rewritable memory is used, but a memory that can be written only for the first time may be used according to the application. The antenna 26 extends along the Y direction on both sides of the IC chip 24. Here, when the tag mounting sheet 10 is viewed in plan, the extending direction of the antenna 16 of the first tag 12 is orthogonal to the extending direction of the antenna 26 of the second tag 22. In the present embodiment, the first tag 12 and the second tag 22 are arranged on the mount 10A so that the extending direction of the antenna 16 of the first tag 12 and the extending direction of the second antenna 16 are orthogonal to each other. The first tag 12 and the second tag 22 are arranged such that the extending direction of the antenna 16 of the first tag 12 and the extending direction of the second antenna 16 intersect within a range of 90 degrees to 110 degrees. It is good also as a structure arrange | positioned on the base_sheet | mounting_paper 10A.

  Next, the operation of the tag information writing system 80 of the first embodiment will be described. As shown in FIG. 1, the tag mounting sheet 10 picked up from the sheet supply device 90 is nipped and conveyed by the conveyance roller 94, passes through the conveyance path 82, and is supplied to the tag information writing device 40. The tag mounting sheet 10 is supplied to the tag information writing device 40 so that the short direction (row direction X) is the transport direction E (see FIG. 4). The supplied tag mounting sheet 10 is detected at its leading end or trailing end by an optical sensor (not shown). Based on this detection signal, the controller 58 drives the drive motor 74 to rotate the conveyor belt 60 and the conveyor belt 70 that is driven by the drive motor 74, so that the tag attachment sheet 10 is nipped and conveyed to a predetermined position.

  When the tag attachment sheet 10 reaches the position of FIG. 5, the controller 58 stops the drive motor 74 and temporarily stops the conveyance of the tag attachment sheet 10. The position in FIG. 5 is the position where the antenna 48A of the antenna unit 46A and the antenna 16 of the first tag 12 overlap in plan view, particularly the position where the antenna in this embodiment overlaps, for example, the IC chip 14 The both ends of the antenna 16 extending to both sides of the antenna 16A indicate positions where they overlap the antenna 48A. After the tag attachment sheet 10 is stopped, the controller 58 transmits electronic information for writing to the radio wave conversion control unit 50A of the antenna unit 46A.

  The radio wave conversion control unit 50A converts the electronic information for writing from the controller 58 into radio waves, and transmits the radio waves toward the antenna 16 of the first tag 12 that overlaps the antenna 48A. The antenna 16 receives this radio wave. The received radio wave is converted into energy (energy obtained by the resonance action of the antenna) and signal (electronic information) in the electric circuit of the IC chip 14. The IC chip 14 supplied with energy writes electronic information in a memory (stores in the memory). After the writing to the memory is completed, the controller 58 transports the tag attachment sheet 10 to the downstream side again.

  Here, the radio wave transmitted from the antenna 48A to the antenna 16 is polarized as shown in FIG. 8 (the vibration direction of the polarized wave is the X direction (or the transport direction)). Since the antenna 26 of the second tag 22 adjacent to the first tag 12 in the Y direction extends in the Y direction, the strongest radio wave is obtained when the polarized wave whose vibration direction is the carrying direction (Y direction) is received. However, when receiving polarized waves that are orthogonal to the transport direction (X direction), the radio waves are too weak to obtain energy for operating the IC chip 24 of the second tag 22. That is, even if radio waves are transmitted from the antenna 48A to the antenna 16, the second tag 22 does not operate (that is, does not malfunction), and thus erroneous writing to the second tag 22 is suppressed.

  In the present embodiment, the tag attachment sheet 10 is transported again after a predetermined time after the electronic information for writing is transmitted from the controller 58 to the radio wave conversion control unit 50A. However, the present invention is limited to this configuration. First, in order to prevent a writing failure or the like, after the writing of the IC chip 14 to the memory is completed, electronic information notifying the completion of writing is transmitted from the IC chip 14 to the controller 58 via the antenna 16 and the antenna 48A. Also good. In FIG. 6, the first tag 12 for which writing of electronic information is completed in FIG. 5 is painted black.

  Next, when the tag attachment sheet 10 reaches the position of FIG. 6, the controller 58 stops the drive motor 74 and temporarily stops the conveyance of the tag attachment sheet 10. 6 is a position where the antenna 48A of the antenna unit 46A and the antenna 16 of the first tag 12 overlap and the antenna 48B of the antenna unit 46B and the antenna 26 of the second tag 22 overlap in plan view. . After the tag attachment sheet 10 stops, the controller 58 transmits electronic information for writing to the radio wave conversion control unit 50A of the antenna unit 46A, and transmits the electronic information for writing to the radio wave conversion control unit 50A of the antenna unit 46B.

  The radio wave conversion control unit 50A converts the electronic information from the controller 58 into radio waves and transmits the radio waves toward the antenna 16 of the first tag 12 that overlaps the antenna 48A. The antenna 16 receives this radio wave. The received radio wave is converted into energy and a signal (electronic information) by the electric circuit of the IC chip 14. The IC chip 14 supplied with energy writes electronic information in a memory (stores in the memory). Similarly, the radio wave conversion control unit 50B converts the electronic information from the controller 58 into radio waves and transmits the radio waves toward the antenna 26 of the second tag 22 that overlaps the antenna 48B. The antenna 26 receives this radio wave. The received radio wave is converted into energy and a signal (electronic information) by the electric circuit of the IC chip 24. The IC chip 24 supplied with energy writes electronic information in a memory (stores in the memory). After the writing to the memory is completed, the controller 58 transports the tag attachment sheet 10 to the downstream side again. In FIG. 7, the first tag 12 and the second tag 22 for which writing of electronic information has been completed in FIGS. 5 and 6 are painted black.

  Next, when the tag attachment sheet 10 reaches the position of FIG. 7, the controller 58 stops the drive motor 74 and temporarily stops the conveyance of the tag attachment sheet 10. The position in FIG. 7 is a position where the antenna 48B of the antenna unit 46B and the antenna 26 of the second tag 22 overlap in a plan view. After the tag attachment sheet 10 is stopped, the controller 58 transmits electronic information for writing to the radio wave conversion control unit 50A of the antenna unit 46B.

  The radio wave conversion control unit 50B converts the electronic information from the controller 58 into a radio wave and transmits the radio wave toward the antenna 26 of the second tag 22 that overlaps the antenna 48B. The antenna 26 receives this radio wave. The received radio wave is converted into energy and a signal (electronic information) by the electric circuit of the IC chip 24. The IC chip 24 supplied with energy writes electronic information in a memory (stores in the memory). Thereby, the writing of information to the first tag and the second tag of the tag attachment sheet 10 is completed. After the writing is completed, the controller 58 conveys the tag attachment sheet 10 to the conveyance path 84. The tag attachment sheet 10 passes through the conveyance path 84, is nipped and conveyed by the conveyance roller 98, and is stacked and stored on the storage tray 97 of the sheet storage device 96.

  In the present embodiment, the electronic information written in the first tag 12 and the second tag 22 is the same, but the present invention is not limited to this configuration, and each tag has a separate configuration. Electronic information may be written. When writing different electronic information, the controller 58 may transmit different electronic information for each tag to be written.
