<p><P>PROBLEM TO BE SOLVED: To provide a magnetic pointing device where a leakage magnetic flux to the outside of a magnet is reduced while magnetic flux density at a magnetic sensor side is not reduced, and output sensitivity is increased. <P>SOLUTION: Magnetic sensors 11 are disposed on a mounted board 14 symmetrically by every two along an X axis and a Y axis. A magnetic 12 is NS- magnetized in a vertical direction while the direction of NS is not especially limited. The opposite faces of silicon resin 13 and the mounted board 14 are not adhered. The silicon resin 13 is easily deformed by adding an external force, and immediately restored to an initial state where any external force is not added by removing the external force. Thus, a leakage magnetic flux at the upper part of a figure can be reduced by providing a magnetic yoke 16, and any adverse influence on the surrounding can be prevented. <P>COPYRIGHT: (C)2004,JPO</p> |
