摘要： A drive unit includes: a shaft; a movable body supported by the shaft so as to be displaceable along the shaft; a vibratory actuator configured to drive the movable body; and a support body configured to support the vibrator actuator. The vibratory actuator includes an actuator main body that contacts the movable body and is configured to vibrate to output a driving force to the movable body, an opposing member that contacts the movable body and is positioned so as to face the actuator main body with the movable body interposed therebetween, and a coupling member that is configured to couple the actuator main body with the opposing member and to bias the actuator main body and the opposing member so as to sandwich the movable body therebetween with the movable body kept displaceable along the shaft. The support body supports the vibratory actuator so that the vibratory actuator is displaceable along a biasing direction of the coupling member.

摘要： A vibratory actuator includes a piezoelectric element, a driver element provided on the piezoelectric element and a movable body supported by the driver element. A control unit supplies a first voltage and a second voltage at the same frequency to the piezoelectric element. By supplying the first voltage and the second voltage having a difference phase from a phase of the first voltage by 90°, the piezoelectric element is lead to composite vibration of stretching and bending, thereby causing the driver to make an elliptical motion by the vibration and move the movable body. The control unit switches, during a fine mode, a phase difference between the first voltage and the second voltage between 90° and 0°.

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).
