ABSTRACT:
A sensor coil pattern used in combination with a coordinate input apparatus is provided, which is adapted to exactly detecting positions if a noise source such as an converter or an electrically closed conductor exists in the periphery of the apparatus. The apparatus is provided with a sensor surface having a sensor coil pattern of many sensor coils arranged thereon in parallel with each other in position detecting directions, a position indicator, a coil or a resonance circuit incorporated therein and a switching means so connected as to select simultaneously one of a plurality of a sensor coils, wherein said many sensor coils include a predetermined number of sensor coils individually connected to the switching means, said predetermined number of sensor coils including at least one or a plurality of sensor coils counted from one end of the arrangement.
