PURPOSE:To accelerate by securing one of ends of a vibrator in a vibrating direction in the vibrating direction, supporting the other end side movably to the vibrating direction, and energizing the entire vibrator to a moving body from a direction perpendicular to the vibrating direction. CONSTITUTION:A reverse side X1 to an edge X in contact with a moving body 5 of the side of a vibrator 1 in a telescopically vibrating direction is supported by support means 6 for so controlling it as not to move in the telescopically vibrating direction. Further, a reverse side X2 to a side having the edge X in contact with the body 5 of the side perpendicular to the side of the telescopically vibrating direction of the vibrator 1 is supported by energizing means 7 for supporting it movably to the vibrating direction and pressing the vibrator 1 to the body 5 side. Thus, a deviation originally generated at the fixed end side of the vibrator is added to the end in contact with the free end side, i.e., the body, i.e., about twice, and the speed becomes about twice. |
