Abstract
An electronic equipment has a rotational operation member that can be downsized and has high detection reliability. The electronic equipment includes a rotational operation member, a click mechanism providing a click feeling at each predetermined rotation angle, and a magnetic field generating member. A first magnetic field detecting part detects variation of a first direction-related magnetic field generated by the magnetic field generating member, and a second magnetic field detecting part 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 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.
