ABSTRACT:
A faulty operation prevention circuit for an infrared-ray remote controller comprising inverter for inverting a transmission signal from the infrared-ray remote controller, a first pulse generation circuit for generating pulses in response to an output signal from the inverter, each of the pulses having a first width, a noise identification unit for identifying an optical noise contained in the transmission signal from the infrared-ray remote controller in response to the output signal from the inverter and the output pulses from the first pulse generation circuit, the noise identification unit having first and second transistors, and a second pulse generation circuit for generating a pulse in response to an output signal from the noise identification unit, the pulse having a second width. A system body receives no transmission signal from the infrared-ray remote controller in response to the output pulse from the second pulse generation circuit when the optical noise is contained in the transmission signal from the infrared-ray remote controller. Therefore, a faulty operation of the system body can be prevented.
