Abstract
Official abstract text for this publication.
An actuator for a camera according to an embodiment includes a base having an inner space formed therein, a carrier provided inside the base and configured to move in at least one direction among an optical axis direction, a first direction perpendicular to the optical axis and a second direction perpendicular to the optical axis and the first direction; and a damper provided to the carrier or the base and configured to have a shape extending in two or more directions among the optical axis direction, the first direction and the second direction.
First claim
Opening claim text (preview).
What is claimed is: 1. An actuator for a camera, comprising: a base having an inner space formed therein; an autofocus (AF) carrier configured to move in an optical axis direction; an optical image stabilization (OIS) OIS carrier provided inside the AF carrier and configured to move in a first direction perpendicular to the optical axis and a second direction perpendicular to the optical axis and the first direction; a stopper configured to prevent the OIS carrier from moving in the optical axis direction and provided at the AF carrier; and a damper provided at an outer vertex portion of the stopper and configured to have a shape extending in the optical axis direction, the first direction and the second direction; wherein the damper includes: a planar part perpendicular to the optical axis; a first part bent at an outer side of the planar part to extend downward; and a second part bent at another outer side of the planar part, located different from the first part, to extend downward and being perpendicular to the first part, wherein the damper is configured to have a margin space formed between the first part and the second part. 2. A multi-directional damper provided to an actuator for a camera, wherein the actuator comprises: a base having an inner space formed therein; an autofocus (AF) carrier configured to move in an optical axis direction; an optical image stabilization (OIS) OIS carrier provided inside the AF carrier and configured to move in a first direction perpendicular to the optical axis and a second direction perpendicular to the optical axis and the first direction; and a stopper configured to prevent the OIS carrier from moving in the optical axis direction and provided at the AF carrier, wherein the multi-directional damper comprises: a planar part perpendicular to the optical axis; a first part bent at an outer side of the planar part to extend downward; and a second part bent at another outer side of the planar part, located different from the first part, to extend downward, and being perpendicular to the first part, wherein the multi-directional damper is configured to have a margin space formed between the first part and the second part; and the multi-directional damper is provided at an outer vertex portion of the stopper and configured to have a shape extending in the optical axis direction, the first direction and the second direction.
