Electronic equipment that determines rotation direction and rotating amount of rotational operation member

An electronic equipment comprising:

• a rotational operation member rotatably held with respect to a rotation axis;
• a click mechanism configured to provide a click feeling at each predetermined rotation angle by rotation of the rotational operation member;
• a magnetic field generating member having magnetic poles with different magnetic properties arranged at regular intervals;
• a first magnetic field detecting part having a first detection axis and configured to detect a variation of a first direction-related magnetic field generated by the magnetic field generating member;
• a second magnetic field detecting part having a second detection axis and configured to detect a variation of a second direction-related magnetic field generated by the magnetic field generating member, the second direction being different from the first direction;
• and
• a calculating unit configured to calculate a rotation amount and a rotation direction of the rotational operation member based on the variation of the first direction-related magnetic field and the variation of the second direction-related magnetic field that are 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,
• wherein the first detection axis and the second detection axis are arranged respectively at different angles to a polarized surface of the magnetic field generating member, and
• wherein the first magnetic field detecting part changes a first magnetic field signal depending on whether the first direction-related magnetic field exceeds a predetermined threshold,
• the second magnetic field detecting part changes a second magnetic field signal depending on whether the second direction-related magnetic field exceeds the predetermined threshold, and
• the calculating unit calculates the rotation amount and the rotation direction of the rotational operation member based on the first and second magnetic field signals.
