SMALL CAMERA ACTUATING APPARATUS USING A PIEZOELECTRIC ELEMENT |
摘要 |
The present invention relates to a small camera actuating apparatus, and more particularly, to a small camera actuating apparatus using a piezoelectric element, which actuates a lens holder in the upward and downward directions using a piezoelectric element to transfer a lens. The small camera actuating apparatus of the present invention includes: a lens holder with a lens mounted therein, and which is actuated in an optical axis direction; a first piezoelectric element and a second piezoelectric element; and an operating member having an actuating portion contacting the outer surface of the lens holder. The actuating portion moves in an elliptical manner to actuate the lens holder in an optical axis direction when voltages having a phase difference of 90 degrees are applied to the first piezoelectric element and the second piezoelectric element. |
