TACTILE SENSATION PROVIDING APPARATUS AND CONTROL METHOD OF TACTILE SENSATION PROVIDING APPARATUS

摘要

A tactile sensation providing apparatus includes a piezoelectric element 1, a detection unit 7 for detecting each pressing and releasing based on an output voltage of the piezoelectric element 1, a drive unit 4 for driving the piezoelectric element 1 synchronously with the detection of each pressing and releasing by the detection unit 7 and thereby providing a tactile sensation, a discharge unit 5 for discharging the piezoelectric element 1 after the driving of the piezoelectric element 1 before start of detection of next releasing or pressing, and a voltage fixing unit 11 for fixing, after the detection of the pressing or releasing by the detection unit 7 before the start of the detection of the next pressing or releasing, an input voltage of the detection unit 7 at a predetermined voltage.
