Abstract

PURPOSE:To adjust phase automatically, and to obtain an excellent efficiency of operation by a simple structure, by applying a secondary output generated by applying an output of an oscillator to a piezoelectric element on the thrust-up side to a piezoelectric element on the kick-out side. CONSTITUTION:Piezoelectric elements 2a-2c are stuck to a base body 1 as a group A1, and piezoelectric elements 3a-3c are stuck as a group A2. Piezoelectric elements 5a, 5b are pasted to a driver 4 as a group B. When the group A1 is driven first, output voltage is acquired from the group A2 while being delayed at approximately 30 deg. at a resonance point. When voltage delayed at approximately 30 deg. generated from the group A2 is applied to the group B, the driver 4 is bent in the longitudinal direction while being slightly delayed in addition to the vertical direction by the third mode of the base body 1. Accordingly, when a slider is pressure-welded to the nose of the driver 4 previously, the slider can be moved in either left or right, direction.
