Title:
位置指示器及び座標入力装置
Document Type and Number:
Japanese Patent JP7323336
Kind Code:
B2
Abstract:
A position indicator includes: a pressure detector that detects a pressure applied to a tip portion as an electrical displacement amount corresponding to a magnitude of the pressure; a pressure output circuit that outputs pressure information indicating a first polarity or a second polarity, the pressure information indicating the first polarity if the electrical displacement amount detected by the pressure detector is greater than or equal to a predetermined value, the pressure information indicating the second polarity if the electrical displacement amount detected by the pressure detector is less than the predetermined value, the predetermined value being larger than a value of the electrical displacement amount detected by the pressure detector when no pressure is applied to the tip portion of the core body; and a transmitting circuit that transmits the pressure information indicating the first polarity or the second polarity output circuit to a position detecting device.
