Abstract

【課題】対象となる無線タグ回路素子を効率よく探索する。 【解決手段】複数の無線タグＴに対し無線通信を行うリーダ１であって、リーダ１の通信可能領域２０において存在が推定される全タグ推定個数Ｘを推測し、探索対象である複数の無線タグＴのタグＩＤの検出タグリストを記憶するメモリ６と、このメモリ６に記憶された検出タグリスト内の複数のタグＩＤを順次指定しながら、対応する無線タグＴから個別に情報を取得する複数タグ検出モードと、通信可能領域２０内のすべての無線タグＴに対し情報取得を図った後、その取得された情報の中から検出タグリスト内のタグＩＤを取得する全タグ応答モードとを、全タグ推定個数Ｘに応じて切り替える。
