摘要:
An image photographing module is provided that includes: a lens unit and has a guide hole guiding the movement of the lens unit; a module supporting unit disposed at the back of the lens unit along the optical axis, wherein a driving axis that is movably inserted into the guide hole is coupled to the module supporting unit; a shutter unit that controls the amount of light incident on the lens unit and is disposed in front of the lens unit such that the shutter unit is substantially included within the overall perimeter of the lens unit; and a lens driving unit that is disposed substantially within the combined perimeter of the shutter unit and the lens unit. A curved vibration piezoelectric motor is also included that moves the lens unit along the optical axis using friction with the driving axis.
