Abstract: An optical mechanism is provided, including an optical member, a reflecting element, a holder, and a housing. The optical member includes a first optical lens and a second optical lens. Light propagates into the optical mechanism in a first direction and is reflected by the reflecting element to propagate through the first and second optical lenses in a second direction. The holder supports the first and the second optical lenses, wherein the first and second optical lenses define an optical axis parallel to the second direction. The housing has a lower cover and a top cover, wherein the holder is accommodated in the housing. The first optical lens is closer to a light-entering end of the optical member than the second optical lens, and the first optical lens is larger than the second optical lens.

Abstract: An optical element driving mechanism is provided. The optical element driving mechanism includes a fixed portion, a movable portion, a plurality of first elastic elements, and a first driving assembly. The movable portion is movably connected to the fixed portion, and includes a holder to hold an optical element, wherein the optical element has an optical axis. The first elastic elements are elastically connected to the fixed portion and the movable portion. The first elastic elements extend in a first direction, and the first direction is perpendicular to the optical axis. The first driving assembly drives the movable portion to move relative to the fixed portion in a direction that is perpendicular to the first direction. The first driving assembly is electrically connected to the first elastic elements.
