  • Patent number: 11439435
    Abstract: A stage device capable of performing piercing vibration and translational driving by using one actuator, and performing very low-speed driving in the translational driving with high accuracy. The stage device includes an X stage having a vibration actuator that includes an vibration element and a contact body, one of which is a movable body connected to an object to be driven, and drives the object to be driven in an X-axis direction, and a control section that controls driving of the vibration actuator. The control section causes two-phase AC voltages to be applied to an electromechanical energy conversion element to thereby excite predetermined vibrations in the vibration element, to drive the vibration actuator by switching between a movement mode for moving the object to be driven in the X-axis direction and a vibration mode for vibrating the object to be driven in the X-axis direction.
