Abstract

PURPOSE:To prevent a door from being unlocked even when a person discriminating device operates by the operation of a person who comes out of a room by making the output of a human body detecting device effective with locking the door when the person discriminating device discriminates a person after the human detecting device operates. CONSTITUTION:The title device is provided with a human body detecting device 7 to detect a person near an entrance. When a person discriminating device 6 outside the entrance operates, an AND gate 20 as a canceling command circuit outputs a door unlocking signal and makes the output of the human body detecting device 7 ineffective. When, after a prescribed time passes form when the human body detecting device operates, the person discriminating device 6 operates, a monostable element 15 as a locking command circuit outputs a door locking signal and makes the output of the human body detecting device 7 effective. When this locking command at the time of the action of this locking command circuit 15, when the human body detecting device operates, an alarm 27 sounds.
