<p><P>PROBLEM TO BE SOLVED: To provide a coordinate input device and its control method and its program for easily simplifying the circuit configuration of an indicator, and easily changing a coordinate output mode. <P>SOLUTION: In this coordinate input device for calculating the position of the indicator for operating position input to a display face configuring an input face based on a reception timing received by a plurality of detecting parts arranged at the peripheral part of the display face, a Tp signal detecting circuit 671 detects a phase signal associated with a phase delay time for an input signal from the indicator among the detection signals of the plurality of detecting parts. Then, a Tp signal selection circuit 68 decides the operation mode of the indicator based on the detection signal. <P>COPYRIGHT: (C)2003,JPO</p> |
