Abstract:
A position detector includes a position pointer having an AC signal generation circuit that is disposed in a housing and that transmits an AC signal, and a sensor that receives the AC signal. The position detector detects the position pointed to by the position pointer on the sensor. The position pointer includes at least three electrodes electrically isolated from each other, and a control circuit that controls so that the AC signal is selectively supplied to the electrodes, and so that identification information identifying the electrode to which the AC signal is selectively supplied is generated and transmitted to the sensor. The position detector further includes a position detection circuit that detects the position based on the AC signal, and an angular information calculation circuit that calculates the rotation angle and/or the tilt angle of the position pointer based on the AC signal and the identification information.

Claim (Index 1):
A position detection system comprising:\n a position pointer having a pen-shaped housing that includes an AC (alternating current) signal generation circuit configured to generate an AC signal; and a sensor including a sensor surface which, in operation, receives the AC signal transmitted from the position pointer, the position pointer including:\n a control circuit, \n a first electrode positioned on an axis of the pen-shaped housing in a tip portion of the pen-shaped housing, to which the control circuit supplies the AC signal from the AC signal generation circuit, and \n a second electrode positioned separately from the first electrode in the tip portion of the pen-shaped housing, which the control circuit selectively sets to a defined potential, \n the sensor including:\n a plurality of first conductors arranged in a first direction and a plurality of second conductors arranged in a second direction different from the first direction, \n a position detection circuit which, in operation, detects a position indicated by the position pointer on the sensor surface based on the AC signal transmitted from the first electrode of the position pointer and received at the sensor surface; and \n an angular information calculation circuit which, in operation, calculates at least a tilt angle of the position pointer relative to the sensor surface based on the AC signal, which is transmitted from the first electrode of the position pointer when the second electrode of the position indicator is set to the defined potential.
