Abstract
A signal waveform detection circuit detects the three-dimensional coordinate value of an indicating tool which is defined in the first, second, and third dimensions. An arithmetic control circuit compares the coordinate value in the first dimension of the three-dimensional coordinate value with a predetermined value, and controls outputting of the coordinate values in the second and third dimensions on the basis of the comparison result.
