とを特徴とする座標検出装置。 In a coordinate detection device that uses a periodic signal of a specific frequency as a coordinate detection signal to detect the position of a coordinate indicator placed on a tablet, any one of two or more coordinate detection signals with different frequencies is used. A coordinate detection device characterized by comprising a coordinate detection signal transmission/reception frequency selection switching means that can selectively use coordinate detection signals of frequencies.
