PROBLEM TO BE SOLVED: To easily recognize an opened/closed state of an opening/closing body. SOLUTION: A lighting/flashing mode (brightness, a flashing speed, a luminescent color, etc.) of an opened/closed state guiding lamp is changed on the basis of positional information from a position detecting means, that is, depending on whether a shutter curtain 2 as an opening/closing body means is in an opened motion or a closed motion, whether a closed-side leading end of the shutter curtain is positioned near a lower limit or an upper limit, or the like. The lighting or flashing mode (the brightness, the flashing speed, the luminescent color, etc.) of the opened/closed state guiding lamp means is changed so that an area sensor 10 can easily recognize which of a fully closed state and a fully opened state is imparted to the opening/closing body means, when it detects that a user gets into a prescribed area.
