Abstract

PURPOSE:To use an LED display part as interior decoration and to prevent outsiders from finding the presence state by operating a pressure-sensitive switch at the time of person's sitting in a chair to light the LED display part through a transmitter or receiver and forming the LED display part into a flowery or decorative pattern. CONSTITUTION:When sitting in a chair 1 is detected by a pressure-sensitive switch 2 or the like built in the chair 1, this detection signal is transmitted to a receiver 7 by a radio wave, and the receiver 7 transmits it to an intra-hall display control unit 9 through an AC power supply circuit 10. When receiving the signal, the display control unit 9 lights a preliminarily designated flowery and color LED out of plural LEDs 8a-8e built in artificial flowers or the like. Since the absence, the presence, the leave, or the like of a specific person is discriminated and displayed on a display part 8 by the flower and the color in this manner, the display part 8 is used as interior decoration and outsiders are prevented from detecting the presence state.
