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).

摘要： An ultrasonic actuator includes: an actuator body (5) including an actuator body (50); a control circuit (150) for setting a driving frequency; power supply sources (191, 192) for applying a driving voltage having the driving frequency to the actuator body; and a memory (170) for storing data related to a difference between antiresonance and resonance frequencies of the actuator body (50). The control circuit (150) determines, based on a reference frequency where a current value of a current fed to the piezoelectric element (50) is local minimum and the data stored in the memory (170), a lower limit of a control range of the driving frequency so that the lower limit is equal to or higher than a frequency where the current value of the current fed to the piezoelectric element (50) is local maximum and determines the driving frequency to be a frequency in the control range.

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.
