<p>PROBLEM TO BE SOLVED: To provide an inputting device in which information indicating an operational position and the strength of the operation can be obtained. SOLUTION: When a substrate 10 equipped with piezoelectric elements 1-4 is beaten, the beat impulse is propagated through the substrate, and the propagated impulse is converted into a voltage by the piezoelectric elements. The applied impulse is detected by an analog/digital converter 15 by using the four piezoelectric elements attached to previously decided coordinates as one unit, and each output voltage is compared by an arithmetic circuit 19A so that the beaten position is relatively obtained. Moreover, the attenuation of the impulse is estimated by the arithmetic circuit 19A so that beat strength is obtained. The position information and the strength information are encoded by encoders 21 and 22, and outputted to the outside.</p> |
