Abstract
An adjustable lens assembly includes a lens barrel for carrying a lens, at least one guiding member having a shaft axis parallel to the optical axis of the lens barrel for guiding the direction of motion of the lens barrel, a gear shaft driven by a driving source, a driving member meshing with the gear shaft, and a connection mechanism connecting the lens barrel and the driving member. The connection mechanism is capable of adjusting itself with multiple degrees of freedom so that if there is three-dimensional skew bias between the gear shaft and the optical axis or the guiding member, the lens barrel can be driven smoothly.
