Abstract
A reflecting module for optical image stabilization (OIS) includes a housing; a rotation holder provided in the housing and comprising a reflecting member; a rotation plate provided in the housing between an inner wall of the housing and the rotation holder so that the rotation holder is supported by the inner wall of the housing via the rotation plate; and a driving part configured to apply a driving force to the rotation holder to move the rotation holder.
Claims18
A reflecting module for optical image stabilization (OIS), the reflecting module comprising:
- a housing;
- a rotation holder disposed in the housing and comprising a reflecting member;
- a rotation plate disposed in the housing between an inner wall of the housing and the rotation holder so that the rotation holder is supported by the inner wall of the housing via the rotation plate;
- a driving part configured to apply a driving force to the rotation holder to rotate the rotation holder around two axes substantially perpendicular to an optical axis;
- a pulling magnet disposed on one of the housing and the rotation holder;
- and
- a pulling yoke disposed on another one of the housing and the rotation holder,
- wherein the rotation holder is pressed against the inner wall of the housing via the rotation plate by an attractive force between the pulling magnet and the pulling yoke in an optical axis direction.
A reflecting module for optical image stabilization (OIS), the reflecting module comprising:
- a housing;
- a rotation holder supported in the housing by friction;
- a rotation plate disposed between an inner wall of the housing and the rotation holder;
- a reflecting member disposed on the rotation holder;
- a driving part configured to rotate the rotation holder relative to the housing;
- a pulling magnet disposed on one of the housing and the rotation holder;
- and
- a pulling yoke disposed on another one of the housing and the rotation holder,
- wherein the rotation holder is pressed against an inner wall of the housing via the rotation plate by an attractive force between the pulling magnet and the pulling yoke.
