Position pointer

A position pointer for use with a position detection sensor, comprising:

• a first electrode configured to receive an AC signal from said position detection sensor;
• a transmission signal production circuit configured to produce a signal, based on which said position detection sensor detects a position;
• a second electrode different from said first electrode and configured to receive the signal produced by said transmission signal production circuit;
• a signal detection circuit configured to detect whether or not the AC signal from said position detection sensor is received through said first electrode;
• and
• a transmission controlling circuit configured to control transmission of the signal from said transmission signal production circuit through said second electrode in response to an output from said signal detection circuit,
• wherein said first and second electrodes are disposed at the same end portion of said position pointer, and
• wherein the signal based on which said position detection sensor detects a position is transmitted from said second electrode in response to the detection of the AC signal received from said position detection sensor through said first electrode.
