Disclosed herein is a lens actuating module for realizing focus adjustment and optical zooming. The lens actuating module includes a rod which is disposed on one side of a lens barrel on which at least one lens is mounted, and has an axis direction corresponding to an optical axis direction of the lens barrel, a driving force transmission member which has a conjoining recess to be conjoined with an outside surface of the rod and has magnetism so as to be conjoined with the outside surface of the rod due to a magnetic force, and a piezoelectric actuator which is disposed on one side of the driving force transmission member in the optical axis direction to provide an axis direction driving force to the rod via the driving force transmission member.

There is provided a flat type piezoelectric ultrasonic motor for generating a rotation force to a rotor by ultrasonic vibrations. In the piezoelectric ultrasonic motor, a vibrator is formed of elastic material at a given size, a plurality of piezoelectric plates are attached on the vibrator, a rotor is drivingly connected to the vibrator thereby to be rotated, and a power source unit applies driving voltages to the piezoelectric plates. The piezoelectric plates are arranged on quartered surface areas of the vibrator in such a way that longitudinal axes of neighboring piezoelectric plates form a given angle therebetween and opposing piezoelectric plates have opposite polarizations, and the power source unit applies alternating driving voltages to the piezoelectric plates thereby to make the rotor rotated, thereby making it possible to simplify the piezoelectric plates' shape, minimize its size and enhance its driving efficiency.

An image sensor module with a zooming function is disclosed. The sensor module consists of first and second barrels for respectively holding condensing lenses used for image capture, and a housing having a guide channel at a sidewall thereof and movably and stably receiving the first extensions of the first and second barrels in the guide channel such that the first and second barrels are moved along a focusing axis of the condensing lenses. The sensor module also has a motor for generating a rotating force, a motor gear formed on the output shaft of the motor, and a means for controlling the interval between the first and second barrels by converting a rotating action of the motor gear into a linear movement of the first and second barrels in a horizontal direction. In the sensor module used in a variety of electronic apparatuses, the condensing lenses are movable to change their positions, thus accomplishing a zooming effect while precisely condensing light beams to produce clear images.
