摘要： A drive unit includes a lens frame configured to support a lens, a movable body located outside the lens and configured to be movable with the lens frame, and a vibratory actuator configured to drive the movable body. The vibratory actuator includes an actuator main body contacting the movable body, an opposite member provided at a position which is opposite to the actuator main body so that the movable body is sandwiched between the actuator main body and the opposite member, and a connecting member configured to connect the actuator main body and the opposite member and to bias them toward the movable body. The connecting member is not provided at a side of the movable body where the lens frame is provided, but is provided at an opposite side of the movable body to the side where the lens frame is provided, as viewed in the optical direction.

摘要： A drive unit (1) includes a stage (3), a first ultrasonic actuator (4A) for driving the stage (3) in the X direction, and a second ultrasonic actuator (4B) for driving the stage (3) in the Y direction. In driving the stage (3) in only one of the X and Y directions, one of the first and second ultrasonic actuators (4A, 4B) corresponding to the one of the directions generates a composite vibration of a longitudinal vibration parallel to a contact surface of the stage (3) and a bending vibration orthogonal to the contact surface, while the other ultrasonic actuator generates only a 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.
