Abstract

【課題】対象となる複数の無線タグ回路素子の位置検出を、効率よく短時間で行う。 【解決手段】無線タグ回路素子Ｔｏに対して無線通信を行うためのＲＦ通信制御部９及びリーダアンテナ３を有し、探索対象の少なくとも１つの無線タグ回路素子ＴｏのタグＩＤを検出タグリストで指定し、複数タグ検出モードによってＲＦ通信制御部９及びリーダアンテナ３を介して探索用の通信を行うことで指定された無線タグ回路素子Ｔｏから情報を取得し、これにより情報を取得した特定の無線タグ回路素子Ｔｏに対して単一タグ検出モードにおいて位置検出用の通信を行い、その通信結果に基づき、特定の無線タグ回路素子Ｔｏの位置を検出する。
