Abstract

　複数の無線タグとの間で併行して情報の通信を行い得る無線タグ通信装置を提供する。 　予め定められた関係から、第１の通信に対応して複数のアンテナ１８により受信された受信信号に基づいて、その受信信号に含まれる複数の無線タグ１４からの返信信号を分離する受信信号処理部５４と、その受信信号処理部５４により分離された返信信号に対応する複数の無線タグ１４のうち少なくとも１つの無線タグ１４との間で前記第１の通信に継続する第２の通信を行う情報通信制御部５０とを、備えたものであることから、第１の通信において複数の無線タグ１４からの応答が併行して行われた場合であっても、その第１の通信に継続する第２の通信においてそれら複数の無線タグ１４との間で好適に情報の通信を続行することができる。
