When a stylus pen 4 is set at an optional position on the board, the X and Y sensor lines near said position induce the voltage. A slice level is set at the value lower than the second highest level of the induced voltage of each sensor line when the pen 4 is set between the contiguous sensor lines. While the slice level is set at the value higher than the third highest level of the induced voltage when the pen 4 is set on a sensor line. In such a way, the moving direction of the pen 4 and a sensor line where the next scan is started are detected. Thus the scanning time can be shortened for sensor lines.
