Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a fixed portion, a movable portion, an electromagnetic driving assembly and an elastic member. The fixed portion has a base and a frame that is disposed on the base. The movable portion is movable relative to the fixed portion, and includes a carrier for carrying an optical member with an incident optical axis. The carrier includes a body and a sidewall that extends along the edge of the body. The electromagnetic driving assembly drives the movable portion to move relative to the fixed portion. The movable portion is movably connected to the fixed portion via the elastic member, wherein as viewed along the incident optical axis, the sidewall and the elastic member at least partially overlap.

Abstract: An optical element driving mechanism is provided and includes a movable portion and a fixed portion. The movable portion includes a carrier for carrying an optical member with a first optical axis. The fixed portion has a top surface, a first side surface and a second side surface. The top surface extends in a direction that is parallel to the first optical axis. The first side surface and the second side surface extend in a direction that is not parallel to the first optical axis from the edge of the top surface and face different sides of the optical member. The shortest distance between the optical member and the first side surface is shorter than the shortest distance between the optical member and the second side surface.

Abstract: A reflecting unit is provided, including an optical member holder, an optical member, a frame, a first bearing member, a first hinge, and a first driving module. The optical member is disposed on the optical member holder. The first bearing member is disposed on the frame or the optical member holder. The first hinge is pivotally connected to the optical member holder and the frame. The first driving module can drive the optical member holder to rotate relative to the frame. When the optical member holder rotates relative to the frame, the first hinge rotates relative to the optical member holder or the frame via the first bearing member.
