Patent ID: 8558542

Claim:
An input device comprising: an actuator including a magnetic body which moves and emits magnetic flux, the magnetic body movable rotatably about a rotation center; and a magnetic detector having an upper surface facing the actuator, wherein the magnetic detector includes a plurality of magnetic sensors for detecting the magnetic flux, the plurality of magnetic sensors being arranged in a matrix form having three or more rows and three or more columns along the upper surface of the magnetic detector, wherein the plurality of magnetic sensors includes: a plurality of first magnetic sensors located in a first region at an outer periphery of the matrix form, and a plurality of second magnetic sensors located in a second region of the matrix form interior of the first magnetic sensors, the second region of the matrix form being surrounded by the first region of the matrix form, wherein, in each of the three or more rows and the three or more columns, an interval between magnetic sensors out of the plurality of second magnetic sensors adjacent to each other is larger than an interval between a magnetic sensor out of the plurality of first magnetic sensors and a magnetic sensor of the plurality of second magnetic sensors adjacent to the magnetic sensor out of the plurality of first magnetic sensors, and wherein the rotation center of the actuator is located over the second region of the matrix form.
