<p>PURPOSE: To provide a sensor coil pattern and a coordinate input device capable of detecting fine coordinates even when a noise source or a cloud electric conductor exists around the coordinate input device. CONSTITUTION: The sensor coil patten in the coordinate input device provided with a sensor face 100 consisting of many sensor coils 10 to 17, 20 to 27, 30 to 37, a position indicator and a switching means 110 for simultaneously selecting one or plural sensor coils has one or plural sensor coils counted at least from one end and individually connected to the switching means 110 among these sensor coils 10 to 17, 20 to 27, 30 to 37.</p> |
