A remote control signal receiver includes a plurality of signal reception units. Each signal reception unit includes a light reception window arranged in a housing of an electronic device and a light reception element arranged in the housing facing toward the light reception window. The light reception elements of the signal reception units are mounted on a circuit board. A transmission barrier prevents infrared noise entering the housing through the light reception window of one of the signal reception units from being transmitted to the light reception element of another one of the signal reception units.
