PROBLEM TO BE SOLVED: To identify a visitor more easily without interrupting a work. SOLUTION: An identification signal transmitted from a portable signal generator 130 is received at a wireless receiving section 101. A wireless identification signal received at the wireless receiving section 101 is notified to an indoor master unit 110 through a master unit I/F section 106. The notified identification signal is received at a control section 118 through a slave unit I/F section 119, and the control section 118 delivers the received identification signal to an authentication processing section 112. The authentication processing section 112 authenticates the received identification signal by collating it with registered identification signal information stored in an identification information storage section 111.
