Claim:
1. A touch panel apparatus provided on a display surface of a display part and having a touch panel receiving an operation, the touch panel apparatus comprising: a plurality of piezoelectric elements that vibrate the touch panel; a vibration control part that drives the plural piezoelectric elements based on a set parameter value of a first parameter, a set parameter value of a second parameter, and a set parameter value of a third parameter; a first parameter table that stores a plurality of the parameter values of the first parameter; a second parameter table that stores a plurality of the parameter values of the second parameter; a third parameter table that stores a plurality of the parameter values of the third parameter; a touch sense pattern table that stores a plurality of touch sense pattern values made up of a combination of the plurality of the parameter values of the first parameter, the plurality of the parameter values of the second parameter, and the plurality of the parameter values of the third parameter; and a setting part that sets the parameter value of the first parameter, the parameter value of the second parameter, and the parameter value of the third parameter based on the plurality of the touch sense pattern values stored in the touch sense pattern table, wherein the vibration control part vibrates the plurality of the piezoelectric elements based on the parameter value of the first parameter, the parameter value of the second parameter, and the parameter value of the third parameter, each corresponding to the touch sense pattern values by changing the touch sense parameter values every predetermined time while the touch panel is touched, and when the touch action is ceased, the setting part sets the parameter value of the first parameter, the parameter value of the second parameter, and the parameter value of the third parameter, each corresponding to the touch sense pattern, when the touch action is ceased, as a setting value for vibrating the plurality of the piezoelectric elements.
