Claim:
1. A capacitive pointer apparatus, comprising: a conductive refill and a refill column, the conductive refill penetrating and combining with the refill column; an elastomer, a pressure sensor and a sensor board, the pressure sensor mounted on the sensor board, wherein a tip pressure applied upon the capacitive pointer apparatus is detected by the pressure sensor through pressing the conductive refill, the refill column and the elastomer against the pressure sensor; a control circuit board, the sensor board electrically connecting to the control circuit board to calculate a tip pressure value applied upon the capacitive pointer apparatus; a pointer tip electrically connecting to the control circuit board and surrounding a portion of the conductive refill, the pointer tip generating capacitive detection signals with a touch panel to detect coordinates of the capacitive pointer apparatus; a shield between the pointer tip and the conductive refill to prevent mutual interferences; and a power source, the power source providing the capacitive pointer apparatus with electrical power.
