Based on a signal for selecting a group outputted from a first selection unit and an output signal from the first control unit, a first comparison/judgment unit outputs a group whose light-emitting unit had been lighted upon selection as a finalized group. A second control unit outputs a lighting signal that causes light-emitting units included in the finalized group to be respectively sequentially lighted, and based on the output signal and a signal for selecting a key outputted from a second selection unit, a second comparison/judgment unit judges that a key corresponding to a light-emitting unit that had been lighted upon selection as a finalized key."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Key input device for remote control apparatus, key input method of key input device for remote control apparatus, program, and recording medium","description":"A first control unit outputs, to a lighting control unit, a lighting signal that causes a plurality of light-emitting units provided for each of a plurality of keys for operating to be sequentially li","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8497766","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
