<p>PURPOSE: To enable the simutaneous input of plural points by using an existing line sensor, neither sharing a cross point, generating a ghost point nor setting a limit to a touch location, regarding a touch panel simultaneously inputting plural points. CONSTITUTION: By using a parallel sensing line extending in three directions or more or a radial sensing line making three points or more as centers and placing a transmission module and a reception module at one end of each sensing line and at the other end, respectively, the intersected point Pc of the sensing line corresponding to at least of the two reception modules is determined, for instance. The distance Zr of the sensing line corresponding to other reception module and the intersected point Pc is determined and the distance Zr makes the point Pc which is a prescribed threshold d or below a touch point.</p> |
