Abstract:
1. A tablet apparatus comprising: an operation panel that includes an inputting operation face and has a rectangular shape; a supporting board that supports the operation panel from a back of the operation panel and has a rectangular shape; an inputting position detecting portion that detects an inputting operation onto the inputting operation face and a position of the inputting operating and outputs data of the position; and a first and second piezoelectric substrates, on a front face of which one of a pair of drive electrodes is provided and on a reverse face of which other of the pair of drive electrodes is provided, either the front face or the reverse face of which is fixed to the operation panel or the supporting board, which has a long and slender belt-shaped shape, a length of which is shorter than a length of one side in a longitudinal direction of the operation panel or the supporting board, respectively, wherein when the inputting operation onto the inputting operation face is detected, a drive voltage is applied upon the pair of drive electrodes and the operation panel or the supporting substrate is vibrated by the first and second piezoelectric substrates, which are expanding and contracting, so as to generate a feeling of the inputting operation, wherein the first piezoelectric substrate is fixed to vicinity of one end of first side in a longitudinal direction along the first side of the operation panel or the supporting board along the first side, and the second piezoelectric substrate is fixed to vicinity of one end of a second side in a longitudinal direction along the second side, wherein the one end of the second side is diagonal with respect to the one end of the first side.
