To provide a pointing device for sharply reducing the problem of the fatigue of a user's hand or arm after a long term operation by preventing the moving operation of a cursor on a display screen from being performed only by a user's tip of finger.
This pointing device for moving a cursor displayed on a display screen by the operation of an operating means 5 is provided with a moving amount detecting means 11 for detecting moving amounts corresponding to a discrete distance from a reference position at operation of the operating means 5 backward and forward, an angle of rotation detecting means 12 for detecting the moving amounts, corresponding to the angle of rotation from the reference position at the time of rotating the operating means 5, and a control means 17 for receiving detection signals from the angle of rotation detecting means 12 and the moving amount detecting means 11, and for controlling the movement of the cursor according to the moving direction and moving amounts of the operating means 5.
