Document Type and Number:
Japanese Patent JP6957276
Kind Code:
B2
Abstract:
An electronic equipment (100) includes a rotational operation member that can be downsized and has high detection reliability, a click mechanism (230f, 211, 212) providing a click feeling at each predetermined rotation angle, and a magnetic field generating member (251). A first magnetic field detecting part (121) detects a variation of a first direction-related magnetic field generated by the magnetic field generating member, and a second magnetic field detecting part (122) detects a variation of a second direction-related magnetic field generated by the magnetic field generating member. A rotation amount and a rotation direction of the rotational operation member (200) are calculated based on the variations of the first direction-related magnetic field and the second direction-related magnetic field caused by a change in a positional relation of the first and second magnetic field detecting parts with the magnetic field generating member due to the rotation of the rotational operation member.
