<p>A signal input device which includes an operation panel (8) having an input area in which data are input by touching the operation panel, a plurality of sensors (S1 to S4) located at different places on the operation panel, the sensors receiving vibrations propagated from a touched point on the operation panel, a detection circuit (C1 to C4) for detecting times at which the sensors erceive the vibrations, an arithmetic means (45) for identifying the position of the touched point, a memory means (46) for storing numerical values whereby the input area is divided into a plurality of minor areas, and means (47,45) for judging which minor areas the touched points belong to, on the basis of the arithmetic results of the numerical values and data about the positions of the touched points. <IMAGE></p> |
