Unlock records of door-lock are stored in a limited memory capacity in volume.Fingerprint data input to a fingerprint input section 21 disposed outside a door 11 provided on a doorway 10 is detected, and the detected fingerprint data is verified against previously registered fingerprint data. If it was confirmed that the detected fingerprint data coincided with the registered fingerprint data, an unlock signal is output to unlock the door-lock, and a setting time or start-using time is stored in a storing section having a clock function.
