Camera module
First Claim
1. A camera module comprising:
- a first frame accommodating a lens module;
a first magnet attached to the lens module;
a first coil opposing the first magnet in a first direction perpendicular to an optical axis direction, and configured to interact with the first magnet to generate a driving force in the first direction;
a second magnet attached to the lens module;
a second coil opposing the second magnet in a second direction perpendicular to both the first direction and the optical axis direction, and configured to interact with the second magnet to generate a driving force in the second direction; and
a plurality of yoke parts provided in the first frame, and configured to generate at least a magnetic attraction between a first yoke part and the first magnet in the optical axis direction.

Abstract
There is provided a camera module including a plurality of ball bearings to support the driving of a lens barrel at the time of compensating for unintended camera movement due to disturbance such as hand shake. The lens barrel may be driven in first and second directions, independently, by one driving force exerted in the first direction perpendicular to an optical axis and by another driving force exerted in the second direction perpendicular to both the optical axis and the first direction, thereby preventing driving displacement from being generated at the time of compensating for unwanted motion such as hand shake while securing reliability against external impact, and having reduced power consumption at the time of compensating for the disturbance.

21. A camera module comprising:
-
a housing; a lens module accommodated in the housing; a first magnet coupled to the housing; a second magnet coupled to the housing and disposed orthogonal to the first magnet; a first coil facing the first magnet in a first direction orthogonal to an optical axis direction, and configured to interact with the first magnet to drive the lens module in the first direction; a second coil facing the second magnet in a second direction orthogonal to the optical axis direction, and configured to interact with the second magnet to drive the lens module in the second direction, and a plurality of yoke parts provided in the first frame, and configured to generate at least a magnetic attraction between a first yoke part and the first magnet in the optical axis direction. - View Dependent Claims (22, 23, 24)
