PROBLEM TO BE SOLVED: To provide a rotational operating unit which is equipped with a non-rotational magnet and can use rotation of a magnetic body to excellently generate click feeling and detect rotation.SOLUTION: A rotational operating unit 10 is provided with a rotational operating body 1, a ring-shaped magnet or a plurality of magnets 30, a clicking magnetic body 20, a rotation detecting magnetic body 25, and GMR sensors 31a, 31b. The clicking magnetic body 20 generates click feeling. The rotation detecting magnetic body 25 is used for detection of rotation of the rotational operating body 1. The GMR sensors 31a, 31b detect a magnetic flux which changes with rotation of the rotational operating body 1.SELECTED DRAWING: Figure 2 |
