Claims

[Scope of Claim for Utility Model Registration] (1) A shaft-shaped, hollow body case with a direction indicating mark corresponding to a specific direction on the display screen on its outer surface, and an opening at the bottom end of the body case provided inside the body case. A movable body consisting of a sphere that is rotatably supported in a partially exposed state and a stay whose lower end is fixed to the sphere, and when no external force is acting on the sphere of this movable body, the stay is in a neutral state with no inclination. posture restoring means for elastically holding the stake so as to restore it to the position; tilting direction detecting means for detecting the tilting direction of the stake due to friction when the sphere slides on a surface such as a desk top; A coordinate input device comprising signal sending means for sending a tilt direction signal to a computer as coordinate input data only during the time that the stake is tilted. (2) The inclination direction detection means generates an electric field between the at least four electric field electrodes arranged along the inner periphery of the main body case and the stay, and detects each of the above-mentioned problems associated with the inclination of the stay. 2. The coordinate input device according to claim 1, wherein the tilt direction is detected based on a change in electric field strength.
