More Information
Summary:A position pointer includes a first electrode disposed so as to project from one end portion of a pen-shaped housing in an axial direction; a second electrode disposed in a proximity of the first electrode so as to surround a center axis of the pen-shaped housing; and a signal generation circuit which, in operation, generates a given signal. The signal generated by the signal generation circuit is outputted to a sensor provided in a position detection apparatus. The signal generation circuit, in operation, generates a signal of a first signal level and a signal of a second signal level lower than the first signal level. A signal supply controlling circuit, in operation, selectively supplies the signal of the first signal level and the signal of the second signal level generated by the signal generation circuit to the second electrode.
