Rotation operation detection mechanism and rotation operation detection method

摘要

The rotation operation detection mechanism (101) is formed integrally with the housing (10), the operation surface (11) arranged on the first main surface (1) of the housing (10), and the housing (10). , The operation unit (12, 13, 14) protruding toward the operation surface (11) and the sensor (15) that detects the stress generated in the housing (10) when the operation unit (12, 13, 14) is rotated. ) And.
