Wireless remote controller

Abstract

Abstract PURPOSE:To judge easily sure transmission of a signal of infrared rays or ultrasonic waves with a means of flickering or the like of a target lamp or another lamp, by providing the target lamp, which can be identified easily even in a dark place, near a separated receiving sensor part. CONSTITUTION:The signal of ultrasonic waves received by an ultrasonic microphone 21 provided in a receiving sensor part 5 passes through a wiring 23 and a coupling capacitor 27 and is inputted to an amplifying circuit 28 from a terminal (c). The inputted minute electric signal is amplified, tuned, and waveform-shaped by the amplifying circuit 28 and is inputted to a terminal (f) of a control IC 25 from an output terminal (e). If an air conditioner buried in a ceiling is operated by a remote controller, a transmitting person 2 confirms easily the position of the objective receiving sensor part 5 with a tagret lamp 22 when he opens a door 1 to enter into a dark room and tries to operate an air conditioner 8 by a transmitter 3.
