Abstract
Official abstract text for this publication.
An optical actuator is an optical actuator configured to move an optical element by a driving part, and includes a movable-side member configured to hold the optical element, a fixed-side member configured to support the movable-side member such that the movable-side member is movable, and a cushioning member disposed on the movable-side member, in which the cushioning member includes a first cushioning surface and a second cushioning surface that face the fixed-side member at respective different distances.
First claim
Opening claim text (preview).
The invention claimed is: 1. An optical actuator configured to move an optical element by a driving part, the optical actuator comprising: a movable-side member configured to hold the optical element; a fixed-side member configured to support the movable-side member such that the movable-side member is movable; and a cushioning member disposed on the movable-side member, wherein the cushioning member includes a first cushioning surface and a second cushioning surface that face the fixed-side member at respective different distances, wherein: the cushioning member is such that the first cushioning surface is capable of making contact with the fixed-side member first, and thereafter the first cushioning surface and the second cushioning surface are capable of making contact with the fixed-side member; and after the first cushioning surface makes contact with the fixed-side member, the first cushioning surface collapses, and the second cushioning surface together with the first cushioning surface makes contact with the fixed-side member, and even thereafter, the second cushioning surface collapses. 2. The optical actuator according to claim 1 , wherein the cushioning member is an integrally molded article made of an elastomer. 3. The optical actuator according to claim 1 , wherein the cushioning member includes a protruding portion and a recessed portion, wherein the first cushioning surface is formed on a tip end of the protruding portion, and the second cushioning surface is formed on a bottom portion of the recessed portion. 4. The optical actuator according to claim 3 , wherein the recessed portion is disposed to surround the protruding portion. 5. The optical actuator according to claim 3 , wherein the protruding portion is disposed to surround the recessed portion. 6. A camera module, comprising: an optical actuator according to claim 1 ; and an image capturing device disposed adjacently to the optical actuator. 7. A camera-mounted device, comprising: an camera module according to claim 6 ; and a control part configured to control the camera module.
