Abstract
A primary object is to provide a scanning method resulting in high speed and correct operation in a coordinate data detecting process. The scanning method for succeedingly selecting sensor coils arranged on a sensor plate in a coordinate data input device comprises an interval scanning operation in which a limited number of the whole sensor coils are selected at a predetermined interval space to detect coordinate data of a pointing device. In one preferable mode, the above described interval scanning operation is repeated until a signal representing the existence of the pointing device is detected, and this interval scanning operation is performed on the respective sensor coil arrays. Each interval space includes one to three sensor coils.
