IMAGING LENS UNIT AND IMAGING APPARATUS

摘要

PROBLEM TO BE SOLVED: To achieve the movement of an imaging lens in an optical axis direction and the tilt movement of the imaging lens related to the optical axis with a simple constitution, in an imaging lens unit. SOLUTION: The imaging lens unit includes: the imaging lens 4 for image forming a light from an object on an imaging surface; a lens holder 3 for holding the imaging lens 4; a holder 2 for holding the lens holder 3 so that the lens holder 3 can move along the optical axis of the imaging lens 4 and also can rotate in a tilting direction related to the optical axis thereof; magnets 5 and coils 6 for independently applying a driving force on the lens holder 3 in a direction along the optical axis at least three positions on the outer circumferential part of the lens holder 3; a Hall element 7 for detecting the attitude of the lens holder 3 related to the optical axis; and a control means for controlling the level and the direction of each coil 6 in accordance with the detection output of the Hall element 7.
