In this case, for example, the inspection step is added between step S214 and step S218 in the flowchart of FIG.

  In the second embodiment, the case where an RFID that transmits information corresponding to a position is used to specify the position of the reader / writer has been described. However, the present invention is not limited to this. A so-called passive IC tag that does not have a function of transmitting itself may be used. In this case, power is supplied from the reading unit of the reader / writer as a wireless signal.

  In the second embodiment, the radio wave shielding plate 72 is used as an example to prevent interference by the RFID 24. However, when it is desired to prevent interference more reliably, each RFID 24 is protected by a shield case. You may make it cover individually.

  Furthermore, each configuration in each of the above embodiments may be combined and used according to the purpose. For example, in the first embodiment in which various types of information are written on the IC card, the position specifying label in the third embodiment may be used instead of the position specifying IC card.

  In addition, the configuration (see FIGS. 1 and 2) of the read / write system 10 described in the above embodiment is merely an example, and unnecessary portions may be deleted or newly added without departing from the gist of the present invention. A part may be added.

  Furthermore, the processing flow of various programs described in the above embodiment (see FIGS. 7 and 10) is also an example, and unnecessary steps can be deleted or new steps can be made without departing from the gist of the present invention. May be added or the processing order may be changed.
