Abstract:
A seat unit includes a light receiving circuit configured to output a pulsed light detection signal in two levels depending on a light reception, a switch input circuit configured to output a pulsed on-off signal in two levels depending on whether a switch mounted on the seat is turned on or turned off, a logic circuit configured to output a turn-on signal upon receipt of the light detection signal in a level indicating the light reception and the on-off signal in a turn-on level, a light emitting circuit configured to emit light upon receipt of the turn-on signal, and a delay circuit configured to delay the light detection signal. The switch input circuit cuts off, upon receipt of the delayed light detection signal in a level indicating no light reception, the power supply from a battery to the switch and to output the on-off signal in the turn-on level.
