Abstract:
A capacitive pointer is disclosed. The capacitive pointer comprises a refill, a refill holder, a spring, a control board, a force sensor, an upper shielding, a lower shielding, a tip cover and a battery. The refill comprises a conductor and penetrates through the refill holder. The spring surrounds one end of the refill holder. The refill holder and the spring electrically connect the control board. The force sensor is located on one end of the control board. The refill and the refill holder press the spring to contact the force sensor to detect the pressure force against the refill. The upper shielding and the lower shielding combine to cover the refill, the refill holder and the spring. The tip cover surrounds one end of the refill and the upper shielding and the lower shielding and electrically connects to the control board. The battery provides the capacitive pointer with electrical power.
