On the other hand, an information-input device includes a chassis supporting a keyboard, and an optical system that transmits a light to an operation body operated on the chassis and receives a reflected light of the light. The chassis supporting the keyboard has a recess housing the operation body. The operation portion may be housed in the recess. The second battery is charged when the operation body is housed. And a light emitting of the optical system is stopped when the operation body is housed."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Operation body, information-input device, and information terminal device","description":"An operation body having a pointing function with respect to information includes a chassis having a reflection face, a circuit charging an inner second battery when receiving an electrical power from","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8471809","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.
