Title:
BALL TYPE INPUT DEVICE
Document Type and Number:
WIPO Patent Application WO/2010/131453
Kind Code:
A1
Abstract:
A ball (15) for input operation, a plurality of sensors (13) which generate a detection signal corresponding to a movement of the ball in a predetermined direction, and a signal processing unit (14) which generates a signal corresponding to a moving direction and moving amount of the ball on the basis of the detection signal output from each of the sensors, are provided. The ball is provided with a magnetic body (16) or a magnet, and the sensor is configured by a magnetic sensor and outputs a detection signal in accordance with the change of a magnetic field caused by the displacement of the magnetic body or the magnet corresponding to the movement of the ball. A pointing device can be made smaller and thinner, and a ball type input device which has increased input detection accuracy, is stable, and is easily maintained, can be obtained.
