Abstract
본 발명은 무접촉·재기록 가능한 카드 형태의 광자기 기록 매체를 사용하고, 사용자는 자유롭게 자신의 카드를 변경할 수 있으면서 외부인의 자물쇠에 대한 접근 가능성을 최소화하는 간단한 회로로 구성된 보안 장치를 제공한다. 이 보안 장치는 무접촉 방식의 카드 판독기(3), 기억 비교부(6)및 논리 판단부(7)을 갖추고 다수의 사용자가 하나 또는 복수의 보안 장치에서 별개의 카드키를 동시에 사용할 수 있으며, 카드 기록기(1)로부터 카드를 쉽게 작성하여 명령을 카드를 통해 전달하고 수시로 카드의 내용을 변경할 수 있다.The present invention uses a magneto-optical recording medium in the form of a contactless and rewritable card, and provides a security device composed of a simple circuit that allows a user to freely change his or her card while minimizing the accessibility of an outsider's lock. This security device is equipped with a contactless card reader 3, a memory comparator 6 and a logic judgment unit 7, which allows multiple users to simultaneously use separate card keys in one or more security devices, It is possible to easily create a card from the card recorder 1, to transmit a command through the card, and to change the contents of the card from time to time.
