LENS ACTUATING MODULE USING A PIEZO ACTUATOR

摘要

PURPOSE: A lens actuating module using a piezoelectric actuator is provided to simplify a structure by including driving mechanism with a pre-pressing member which moves in the optical axis direction of a lens barrel. CONSTITUTION: A lens actuating module(200) includes a housing(210), a lens barrel(220), a pre-pressing member(230), and a piezoelectric actuator(100a). The pre-pressing member includes a pre-pressing unit which is extended to the outside direction of a lens barrel. The piezoelectric actuator applies driving force to drive the lens barrel in an optical axis direction.
