Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion, a fixed portion, a first driving assembly, and a plurality of second guiding members. The first movable portion is configured to connect an optical member. The optical member is used for adjusting a direction of a light from an incident direction to an outgoing direction. The first movable portion can move relative to the fixed portion. The first driving assembly is configured to drive the first movable portion to move relative to the fixed portion. The second guiding members include a first ball, a second ball, and a third ball. The first ball, the second ball, and the third ball are disposed in a plane that is perpendicular to the incident direction.

Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a movable portion and a fixed portion. The movable portion includes a holder for holding an optical member with an optical axis. The movable portion is movable relative to the fixed portion. The fixed portion has a housing and a base. The housing is disposed on the base, and includes a top surface and a side surface. The top surface extends in a direction that is parallel to the optical axis. The side surface extends from an edge of the top surface in a direction that is not parallel to the optical axis. The side surface has a rectangular opening.

Abstract: An optical member driving mechanism is provided. The optical member driving mechanism includes a first movable portion used for connecting an optical element, a fixed portion, a first driving assembly used for driving the first movable portion to rotate relative to the fixed portion, and a guiding assembly having a first intermediate element. The first movable portion is movable relative to the fixed portion. The guiding assembly is used for applying a first stabilized force to the first movable portion for making the first intermediate element be in contact with the first movable portion or the fixed portion. The first movable portion is rotatable relative to the fixed portion.
