<p><P>PROBLEM TO BE SOLVED: To solve the problems that conventional transmission/reception by a single sensor coil is easily affected by noise from the outside, and minimization of the shape of a position indicator has a limit. <P>SOLUTION: A position detector can supply larger electric power to the position indicator by making current simultaneously flow through a plurality of coils without applying large current to the single sensor coil. <P>COPYRIGHT: (C)2004,JPO</p> |
