At this time, the set value holding device 6 can hold two kinds of data, and its set value is changed over by a changeover device 5. The changeover device 5 changes over the pieces of data held in the set value holding device 6 when a direction command is changed. The two pieces of data which are held in the set value holding device 6 are formed as unbalanced data in such a way that a movement part 32 can be moved at the same speed or at the same distance even when the movement part is moved to any direction. Thereby, a movement direction can be balanced irrespective of an influence by an ultrasonic vibrator, the movement part, a pressure mechanism and the like.
