Abstract
A tactile sensation providing apparatus includes a piezoelectric element, a detection unitfor detecting each pressing and releasing based on an output voltage of the piezoelectric element, a drive unitfor driving the piezoelectric elementsynchronously with the detection of each pressing and releasing by the detection unitand thereby providing a tactile sensation, a discharge unitfor discharging the piezoelectric elementafter the driving of the piezoelectric elementbefore start of detection of next releasing or pressing, and a voltage fixing unitfor fixing, after the detection of the pressing or releasing by the detection unitbefore the start of the detection of the next pressing or releasing, an input voltage of the detection unitat a predetermined voltage.
