Abstract
A lens-shifting device including a base, two fixing rods, a sliding plate, a first and a second gear set is provided. The sliding plate is slidably mounted on the fixing rods via the fixing rods. A lens is fixed on the sliding plate and the sliding plate has a rack disposed on one side thereof. The first gear set has a first gear and a worm gear co-axial therewith. One of the fixing rods passes through the first gear such that the first gear and the worm gear may rotate relative to the fixing rod. The second gear set having a worm wheel and a second gear co-axial therewith is disposed between the fixing rod and the rack. The worm gear is for driving the worm wheel and the second gear is used for driving the rack such that the sliding plate moves relative to the fixing rods.
