Abstract: An auto-focusing lens module includes a substrate, guiding members positioned on the substrate, an actuator unit, a driving plate, and a lens holder holding a lens therein. The driving plate includes an upper surface and first protrusions on the upper surface in a first circle. A height of each first protrusion gradually decreases along a circumferential direction. The lens holder includes a bottom surface and second protrusions on the bottom surface in a second circle. A height of each second protrusion gradually increases along the circumferential direction. Each second protrusion rests on a respective first protrusion. The guiding members guide the lens holder to move along an optical axis of the lens module. The actuator unit drives the driving plate to rotate, such that the driving plate drives the lens holder to move long the optical axis by the engagement of each second protrusion with the respective first protrusion.

Abstract: A rotation/displacement converting actuator has an actuator unit constituted by a displacing body and an actuator in which the displacing body can be linearly displaced. The actuator has a pair of plate-shaped bases, a rotor, a vibrating element that rotates the rotor, and a cam mechanism for converting rotary motion of the rotor to linear motion of the displacing body. The rotor is fixed to a shaft to which the rotor (cam rotor) is fixed. An outer circumferential surface of the rotor constitutes a cam surface of the cam mechanism. A roller is provided at a tip portion of the displacing body. The roller abuts on the outer circumferential surface (cam surface) of the rotor.
