PURPOSE:To achieve automatic control by providing signal lines along a ceiling rail and also providing external transmission means for outputting position detecting signals by means of the signal lines, signal transmitting means of runners, panel side replying means, and deciding means for the position of each panel. CONSTITUTION:A plurality of signal lines 31 and transmission means from an external operation control board for outputting position detecting signals to respective panels 20 are provided by partitioning partition panels 20 in the routine direction of a hung ceiling 1. Next, runners 5 are provided with signal transmission means so that they can transmit and receive signals to/from the signal lines 31. Reply means on panel 20 side for receiving those transmitted signals and outputting return signals to the signal lines 31 and means for identificating the position of each panel 20 according to return signals received from the signal lines 31 are provided. Then, stable and safe operation can be carried out for a long period without any trouble. |
