Summary:PURPOSE:To easily enter and leave a room by attaching a means to the room door itself to receive the radio information including the information on the prescribed enter-/leave-room permission from a portable medium owned by a person who is permitted to enter and leave the room. CONSTITUTION:When an owner of a tag 1 approaches a door 3 to enter a room, an antenna 5 receives the radio signal transmitted from the tag 1. This received radio signal is sent to a reader part 7 via an information converter 15 and a photoelectric converter 17. The part 7 sends a command to a door controller 9 to open the door 3 after confirming that the received radio information shows a due enter-/leave-room permission. Then the controller 9 opens the door 3 by said door opening command. Thus the owner of the tag 1 can directly enter the room.
