ABSTRACT:
A coordinate position detecting apparatus includes: a scanning unit that scans a predetermined scanning area in predetermined scanning precision along a horizontal direction and a vertical direction with respect to a display screen by employing detection beams respectively. A position of a light shielding article on the display screen is detected in correspondence with scanning positions of the detection beams which are light-shielded. The scanning unit includes: a drive control unit that switches a plurality of scanning modes having different scanning accuracies from each other; and a moving speed detecting unit that detects a moving speed of the light shielding article. The scanning unit selects a predetermined scanning mode from the plurality of scanning modes in response to the scanning speed detected by the moving speed detecting unit to perform a scanning operation.
