LENS HOLDER, LENS DRIVING DEVICE, CAMERA DEVICE AND ELECTRONIC DEVICE

摘要

A lens driving device in which the lens holder is employed, a camera device and an electronic device are also disclosed. The lens holder includes portions formed as having the respective different outer circumferential diameters between the upper side and the lower side of the vertical direction and provided in predetermined areas located in the circumferential direction of the outer circumferential wall of the lens holder around which a coil is to be wound, and a flanged portion that protrudes from the outer circumferential wall of the lens holder toward the radially outward side, wherein the diametrically larger portion among the portions formed as having the respective different outer circumferential diameters between the upper side and the lower side of the vertical direction and the flanged portion are arranged so that they can be spaced away from each other by a predetermined gap.

主权项

1. A lens holder for use with a lens driving device based on the voice coil motor system wherein the lens holder has a predetermined length along the vertical direction and a coil is wound around the outer circumference thereof, the lens holder comprising:
a portion formed on predetermined part located in the circumferential direction of the outer circumferential wall of said lens holder on which the coil is wound around, said portion has respectively different outer circumferential diameters along said vertical direction of said portion; and a flanged portion projecting from the outer circumferential wall of said lens holder toward the radially outward side, wherein a diametrically larger portion having larger outer circumferential diameter among said respectively different outer circumferential diameters along said vertical direction of said portion and said flanged portion are spaced away from each other by a predetermined space along said vertical direction.
