Description

上述した発明を解決する第１の発明は、近接型ＩＣカードとリーダライタとから少なくとも構成される近接型ＩＣカードシステムであって、前記リーダライタは、通信パラメータのネゴシエーション処理を省くために、衝突防止手順を行う際、衝突防止手順が完了していない前記近接型ＩＣカードに初期応答を要求する初期応答要求コマンドを送出するタイミングで、前記初期応答要求コマンドと共に、予め決められている通信パラメータを含む近接型ＩＣカード選択コマンドを送出し、前記近接型ＩＣカードは、衝突防止手順を行う際、前記初期応答要求コマンドと共に前記近接型ＩＣカード選択コマンドを受信すると、前記初期応答要求コマンドのレスポンスを送出する条件が成立している場合、前記初期応答要求コマンドのレスポンスを送出せずに、前記近接型ＩＣカード選択コマンドのレスポンスを前記リーダライタへ送信することを特徴とする。 A first invention that solves the above-described invention is a proximity IC card system that includes at least a proximity IC card and a reader / writer, and the reader / writer performs a collision in order to omit a communication parameter negotiation process. When performing the prevention procedure, at the timing of sending an initial response request command for requesting an initial response to the proximity IC card for which the collision prevention procedure has not been completed, a predetermined communication parameter is set together with the initial response request command sending a proximity type IC card selected command including, the proximity type IC card, when performing the collision avoidance procedure, when receiving the proximity type IC card selection commands with the initial response request command, the response of the previous SL initial response request command Response to the initial response request command Without sending, and transmits a response before Symbol proximity IC card select command to the reader writer.

更に、第２の発明は、第１の発明に記載した近接型ＩＣカードシステムにおいて、前記近接型ＩＣカードを他のシステムでも利用できるように、前記近接型ＩＣカードは、前記初期応答要求コマンドのみを受信した場合、前記初期応答要求コマンドで示される規格に準じた衝突防止手順を実行することを特徴とする。 Further, according to a second invention, in the proximity IC card system described in the first invention, the proximity IC card can use only the initial response request command so that the proximity IC card can be used in other systems. Is received, an anti-collision procedure according to the standard indicated by the initial response request command is executed.

更に、第５の発明は、衝突防止手順を行う際、衝突防止手順が完了していない近接型ＩＣカードに初期応答を要求する初期応答要求コマンドと共に、予め決められている通信パラメータを含む近接型ＩＣカード選択コマンドを受信すると、前記初期応答要求コマンドのレスポンスを送信する条件が成立している場合、前記初期応答要求コマンドのレスポンスを送出せずに、前記近接型ＩＣカード選択コマンドのレスポンスを送信するように構成されていることを特徴とする近接型ＩＣカードである。 Further, the fifth aspect of the present invention provides a proximity type including a predetermined communication parameter together with an initial response request command for requesting an initial response to a proximity type IC card that has not completed the collision prevention procedure when performing the collision prevention procedure. Upon receiving the IC card select command, before Symbol if the conditions for sending a response of the initial response request command is satisfied, without providing the response of the initial response request command, the response of the previous SL proximity IC card select command It is a proximity IC card characterized by being configured to transmit.

更に、第６の発明は、第５の発明に記載した近接型ＩＣカードであって、前記近接型ＩＣカードは、前記初期応答要求コマンドのみを受信した場合、前記初期応答要求コマンドで示される規格に準じた衝突防止手順を実行するように構成されていることを特徴とする。 Further, the sixth invention is the proximity IC card according to the fifth invention, wherein the proximity IC card receives the initial response request command only, and the standard indicated by the initial response request command. It is comprised so that the collision prevention procedure according to may be performed.
