Abstract:
1. A zoom lens control mechanism, for changing a focal distance in an optical axis of a first lens set, comprising: a zoom lens base, disposed at one side of the first lens set and having an image pickup opening, wherein the image pickup opening is in the optical axis of the first lens set; a first lens support, one end of the first lens support is rotatably disposed on the zoom lens base and the other end of the first lens support is with a second lens set; a first switch device, disposed on the zoom lens base, for controlling the rotation of the first lens support, such that the second lens set shifts between an active position and a leaving position along the surface of the zoom lens base, wherein the active position is corresponding to the image pickup opening, and the leaving position deviates from the image pickup opening; a second lens support, one end of the second lens support is rotatably disposed on the zoom lens base and the other end of the second lens support is with a third lens set; and a second switch device, for controlling the rotation of the second lens support along the surface of the zoom lens base, such that the third lens set moves between the active position and the leaving position.
