Abstract
PURPOSE: To make an input unit lightweight and miniature and also to obtain high resolution, by combining a piezoelectric element with an integrated circuit.
CONSTITUTION: Piezoelectric element 13 and the integrated circuit consisting of input circuit 30 and memory cell 31 are provided. Piezoelectric element 13 has elec- trode 12 on the side of sheet 10 and many electrodes 14, arranged in a matrix, on the side of chip 16, electrodes 15 of which correspond to electrodes 14. Then, sheet 10 protects element 13 from a handwriting medium by a ball-point pen, etc., and through electrode 11, electrode 12 is applied with a constant voltage to substrate 16 of a chip including the integrated circuit. Namely, the elapse variation of pressure applied on the surface of sheet 10 by the handwriting medium is converted by element 13 into a voltage, which appears at electrodes 15 and is stored in memory cell 31 as a digital signal by way of input circuit 30, and information on it is led out via output circuit 32.
