Abstract: A lens driving device includes a lens barrel having a lens holder and an extension part extended from the lens holder. The device also includes a piezoelectric vibrator with a piezoelectric body flexed and bent in response to power application with a friction member in contact with the extension part, thereby providing driving power for transporting the lens barrel. The device further includes a preload member having a free end in resilient contact with a rear end of the piezoelectric body to compress the piezoelectric vibrator against the extension part and a guiding part for guiding the transport of the lens barrel in the optical axis direction. This allows a simplified and miniaturized structure, a large transport range with low input power to achieve excellent resolution of positioning, minimal loss of driving power, simplified mechanism for guiding the transport of the lens, and accurate and stable transport of the lens.

Abstract: The invention provides a lens transfer device including at least one lens and a lens barrel. The lens barrel has a lens receiving part with the lens arranged in an inner space thereof and an extension extending radially from an outer surface of the lens receiving part. An actuator has a body and an output member at a leading end of the actuator to contact the extension, and is adapted to expand/contract and bend in response to an external supply voltage to provide a driving force necessary for transfer of the lens barrel through the output member. A pressing member has a free end contacting a rear end of the actuator to force the actuator against the extension, and a guide guides the transfer of the lens barrel along an optical axis.
