The electronic pen includes an electronic pen main body and a pen tip unit configured to be detachable from the electronic pen main body. The pen tip unit includes a pen tip casing in which at least the coil is housed. The electronic pen main body includes a circuit portion of the resonant circuit that is electrically coupled to the coil housed in the pen tip unit when the pen tip unit is attached to the electronic pen main body."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electronic pen of electromagnetic coupling type","description":"An electronic pen of an electromagnetic coupling type has a resonant circuit that includes a coil and that is configured to indicate a position to a position detection sensor through electromagnetic c","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11294480","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.
