Abstract

【課題】無線タグの検出時間を短縮し、探索効率を向上できる無線タグ通信装置を提供すること。 【解決手段】無線タグ通信装置（１）は、応答時に内容を反転可能なセッションフラグ（Ｓ０）を備えた少なくとも１つの無線タグ（Ｔ）に対し無線通信を行うリーダアンテナユニット（３）と、このリーダアンテナユニット（３）での偏波面方向を複数方向に順次切り替え可能な切替スイッチ部（３４１）とを有する。そして、無線タグ通信装置（１）は、通信領域（２０）内に存在する無線タグ（Ｔ）のセッションフラグ（Ｓ０）の内容を反転前状態に統一するための「Ｓｅｌｅｃｔ」コマンドを、順次切り替えられる各偏波面方向にそれぞれ対応する無線タグ（Ｔ）に対し送信した後、セッションフラグ（Ｓ０）が反転前状態である無線タグ（Ｔ）を特定して無線タグ（Ｔ）に記憶されたタグ情報を取得するための「Ｑｕｅｒｙ」コマンドを送信する。
