Abstract
An optical member driving mechanism is provided, including a fixed portion, a movable portion, and a driving module, wherein the movable portion is movably connected to the fixed portion and includes an optical member holder and a spacing member. The optical member holder can support an optical member and has a surface facing the optical member. The optical member can change the moving direction of an external light. The spacing member is disposed between the surface and the optical member, and a gap is formed between the surface and the optical member. The driving module can drive the movable portion to move relative to the fixed portion.
Claims20
An optical member driving mechanism, comprising:
- a fixed portion;
- a movable portion, movably connected to the fixed portion, comprising:
- an optical member holder, supporting an optical member, wherein the optical member can change the moving direction of an external light, the optical member holder comprising:
- a surface facing the optical member;
- a wall surface facing the optical member, wherein the wall surface is not parallel to the surface;
- and
- a glue slot formed on the surface and adjacent to the wall surface;
- and
- a spacing member, disposed between the surface and the optical member and forming a gap therebetween;
- a driving module, driving the movable portion to move relative to the fixed portion;
- and
- an adhesive member,
- wherein the optical member is connected to the wall surface via the adhesive member and the glue slot is configured to receive the redundant adhesive member.
An optical member driving mechanism, comprising:
- a fixed portion;
- a movable portion, movably connected to the fixed portion, comprising an optical member holder to support an optical member, wherein the optical member can change the moving direction of an external light from a first direction to a second direction, the optical member holder comprising:
