  The present invention relates to an electric lock system that controls the locking and unlocking of a door effectively or invalidally by authenticating identification information of a non-contact medium.

  Conventionally, at the entrances and entrances of commercial or public facilities such as hotels and office buildings, and entrances and entrances of apartment buildings or general houses, IC cards etc. An electric lock system that locks and unlocks a door by authenticating identification information stored in the non-contact medium is employed.

  The electric lock system has, for example, an electric lock for electrically locking and unlocking the door built in the door, and a lock button and an unlock button for operating the lock and unlock of the door are provided on the indoor and outdoor door surfaces and wall surfaces, In addition, a receiver that receives identification information from the non-contact medium is provided near the door, and further includes a control unit that authenticates the received identification information and controls locking and unlocking of the electric lock.

  In this electric lock system, when the non-contact medium enters the communicable area of the receiver, the identification information of the non-contact medium is received by the receiver. Furthermore, when the control unit determines the validity of the received identification information and authenticates it as valid, the unlocking operation of the electric lock is set to be valid. In this case, the user can open the door by operating the unlock button to unlock the door. On the other hand, when authenticating that the identification information is invalid (when authentication is not possible), the control unit sets the unlocking operation of the electric lock to be invalid. In this case, even if the user operates the unlock button, the user cannot unlock the door and cannot open the door.

  Therefore, when the non-contact medium is within the communicable area of the receiver, for example, when the user who has the non-contact medium is near the door such as the inside of the entrance, or forgetting to place the non-contact medium near the entrance. In this case, the unlocking operation of the electric lock remains valid. At this time, even a person who does not have a non-contact medium can unlock the door, so that the door is opened or entered illegally.

  Therefore, in recent electric lock systems, a human sensor is provided on the indoor side, and when the presence of a person in the room is detected by this human sensor, the control unit receives the identification information from the non-contact medium. Regardless, the unlocking operation of the electric lock is set invalid (see Patent Document 1 and Patent Document 2). As a result, it is possible to avoid unauthorized opening and entry of a person who does not have a non-contact medium immediately after the legitimate user enters the room.
