使用した駆動装置。 The first piezoelectric element comprises a rotatably supported roller, a first piezoelectric element facing the outer surface of the roller, and a second piezoelectric element facing further outside the first piezoelectric element. The first piezoelectric element is supported so as to be able to move slightly toward and away from the outer surface of the roller, either directly or indirectly through the conveyed object, and the direction of expansion and contraction of this first piezoelectric element when a voltage is applied corresponds to the outer circumference of the roller. The piezoelectric element is oriented in a tangential direction, and the deformation direction of the second piezoelectric element when a voltage is applied is oriented in a direction that presses the first piezoelectric element toward the outer surface of the roller.
