摘要:
A position pointer is provided for use with a position detection sensor, capable of achieving power saving. The position pointer includes: a first electrode configured to receive an AC signal from a position detection sensor; a transmission signal production circuit configured to produce a position signal, based on which the position detection sensor detects a position of the position pointer; a second electrode different from the first electrode and configured to transmit the position signal to the position detection sensor; a signal detection circuit configured to detect whether or not the AC signal from the position detection sensor is received through the first electrode; and a transmission controlling circuit configured to control transmission of the position signal through the second electrode to the position detection sensor in response to an output from the signal detection circuit.
