Patent ID: 7119798

Claim:
A digitizing tablet comprising: an operation panel having an input surface and a rear surface, a support substrate under said rear surface of said operation panel, an input position detector between said operation panel and said support substrate, said input position detector adapted to detect an input received via said input surface and an input position of said input and to output data regarding said input position, the input position detector comprising: a plurality of first electrodes arranged in parallel in a first direction; a plurality of second electrodes arranged in parallel in a second direction an expandable piezoelectric substrate; a pair of drive electrodes fixed to front and rear surfaces of the expandable piezoelectric substrate, the expandable piezoelectric substrate being located between first and second planes respectively defined by a front surface of the plurality of first electrodes and a rear surface of the plurality of the second electrodes and being fixed, directly or via one of said pair of drive electrodes, to said operation panel or said support substrate, and whereby, when an input is detected by the input position detector, the detection of the input is transmitted via vibration by a drive voltage that is applied to said pair of drive electrodes to cause said piezoelectric substrate to vibrate said operation panel or said support substrate thereby generating a feeling of said input.
