Abstract
An input device includes a case, a ball, a magnetic detecting element, a wiring board, and a rocking part. The ball is rotatably accommodated in the case, exposed from an opening of the case, and is embedded with a magnetic substance having a plurality of protrusions or with a plurality of magnets. In a case the magnetic substance is embedded in the ball, a magnet is placed where its magnetism affects the plurality of protrusions. The magnetic detecting element is disposed facing the ball with a certain gap. The switch is mounted on the wiring board. The rocking part is placed between the case and the switch, supporting the case in a swingable manner with respect to the switch. The switch is turned on and off corresponding to a rocking motion of the rocking part. The ball and the magnetic detecting element are attached to the rocking part so that the gap is kept constant with each other when the rocking part rocks.
