Abstract

An optical anti-shake device is disclosed, which includes a base, a cam, a transmission unit, a positioning piece and an elastic element. The cam is installed on the base and is capable of rotating around its axis. The transmission unit is installed on the base and is connected with the cam and drives the cam to rotate. The positioning piece props against the cam and has a follower end that is moved connectively with the cam, and a force-applying end that pushes against an optical element. The cam drives the positioning piece, via the follower end, to move vertically with respect to the base between a fixed position and a detached position. When the positioning piece is at the fixed position, the force-applying end will push against the optical element; when it is at the detached position, the force-applying end will be separated from the optical element. The elastic element is installed between the positioning piece and the base, and keeps pushing the positioning piece against the cam. The efficacy of this invention is that the positioning piece is moved vertically so as to increase the stability of an anti-shake device.
