Digitizing tablet

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 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;
• an expandable piezoelectric substrate;
• a pair of drive electrodes fixed to front and rear surfaces of the expandable piezoelectric substrate said piezoelectric substrate, being fixed to a rear surface of said support substrate, directly or via one of said pair of drive electrodes, such that the rear surface of the expandable piezoelectric substrate is unattached, 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.

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 having a front surface and rear surface, the expandable piezoelectric substrate being fixed to one of the group consisting of (1) the rear surface of the operation panel such that the front surface of the piezoelectric substrate is coplanar with a front surface of the plurality of first electrodes, and (2) the front surface of the support substrate such that the rear surface of the piezoelectric substrate is coplanar with a rear surface of the plurality of second electrodes;
• a pair of drive electrodes fixed to the front and rear surfaces of the expandable piezoelectric substrate;
• 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.
