摘要： In driving a target body only by one of actuators, the target body is smoothly driven.A drive unit (1) includes a stage (3), a first ultrasonic actuator (4A) for driving the stage (3) in an X direction and a second ultrasonic actuator (4B) for driving the stage (3) in a Y direction. When the stage (3) is driven only in one of the X direction and the Y direction, one of the first and second ultrasonic actuators (4A and 4B) which corresponds to the direction generates composite vibration of longitudinal direction parallel to a contact surface of the stage (3) and bending vibration perpendicular to the contact surface of the stage (3). On the other hand, the other one of the first and second ultrasonic actuators (4A and 4B) generates only longitudinal vibration parallel to the contact surface of the stage (3).
