Lens positioning device used in digital camera, includes positioning unit having holder with lens, contacting rotation plate when rotation plate is rotated so that positioning unit is linearly moved with respect to optical axis of lens

摘要

A positioning unit has a hollow barrel holder (30) with a lens, contacting a upper surface of a rotation plate (40) of a actuating unit when the rotation plate is rotated by an piezoelectric actuator (50) so that the positioning unit is linearly moved with respect to an optical axis of the lens by a guide unit.
