Abstract
An actuator includes a base, a stationary frame mounted on the base, a moveable frame received in the stationary frame and supported on the base, a shaft mounted on a side surface of the moveable frame, a flexible printed circuit, a piezoelectric motor, a first guide pole and a second guide pole. The flexible printed circuit is mounted on a sidewall of the stationary frame facing the shaft. The piezoelectric motor is mounted on the flexible printed circuit and engages with the shaft, and the first and second guide poles prevent any misalignment of the movable frame at any time and allow only axial movement of the movable frame.
