Patent ID: 6993304

Claim:
A signal-input status display device for a multi-band receiver, said multi-band receiver comprising: an indicator having a plurality of light-emitting diodes (hereinafter referred to as “LEDs”) emitting different illumination colors as light source elements, for optically mixing individual lights of said respective LEDs, thereby permitting multi-colored light emission; signal detection means for detecting from receiving circuits for respective frequency bands signals each indicating a signal-input level of a received wave; determination and identification means for determining whether a single signal input to one of the frequency bands has been performed or simultaneous signal inputs to a plurality of the frequency bands have been performed, based on states of the signals each indicating the signal-input level, detected by the signal detection means, and identifying said one of the frequency bands to which the single signal input has been performed; and LED control means for performing drive control over said respective LEDs such that an illumination color of said indicator differs according to each of the frequency bands based on information on said one of the frequency bands to which the single signal input has been performed if said determination and identification means has determined the single signal input has been performed, or such that the illumination color of said indicator is different from the colors emitted in a status of the single signal input if said determination and identification means has determined the simultaneous signal inputs have been performed.
