<p>PURPOSE:To obtain a security performance with high reliability by outputting an identification signal at the time of satisfying a prescribed condition corresponding to the read ID information and the combination registration information stored by a storage means. CONSTITUTION:A radio controller 13 is fixedly installed on the side of a position near a door, and it communicates with a pair of ID cards 14 and 15 registered through an antenna 16 installed on the controller. Then, the door 12 is lock/ unlock-operated based on a corresponding signal corresponding to the communication. In such a case, card information on a pair of the ID cards 14 and 15 are previously combined so as to register them in the controller 13 at the time of the correspondence of the controller 13 and a pair of the ID cards 14 ad 15. At the time of radio communication with the cards 14 and 15, information on the two cards are made to correspond to previously registered registration information. When both information correspond and they satisfy the setting condition, the identification signal for opening the door 12 is outputted.</p> |
