LENS DRIVE DEVICE, AUTOFOCUS CAMERA AND CAMERA-EQUIPPED MOBILE TERMINAL

摘要

PROBLEM TO BE SOLVED: To provide a lens drive device capable of moving a lens support in an optical axis direction and executing image stabilization and tilt correction with a simple configuration, and provide an autofocus camera and a camera-equipped mobile terminal.

SOLUTION: A lens drive device 1 provided relating to the invention is provided with: multiple first coils 19a to 19d that are arranged at regular intervals in a circumference direction on an outer periphery of a lens support 5; at least two second coils 16a to 16h that are arranged at intervals of 90 degrees in the circumference direction on the outer periphery of the lens support 5; and magnets 17a and 17b that are provided at a solid body. The magnets 17a and 17b that are provided in a manner facing the first coils 19a to 19d and the second coils 16a to 16h apply a predetermined direct current to the predetermined first coils 19a to 19d in the case of moving the lens support 5 in an optical axis direction and correcting tilt, and they apply current to the predetermined second coils 16a to 16h in the case of moving the lens support 5 in an X-Y direction orthogonal to the optical axis.
