Abstract: An automatic focus system of a projector includes a projecting module, an image catching module, a memory, a micro processor, and a focusing module. The projecting module has an image light source to provide image light, and a projecting lens to project the image light on a screen. The image catching module senses an image on the screen. The microprocessor calculates the sensed image to have a definition value of the image and save the definition value in the memory. The focusing module may move the projecting lens is moved along an optical axis under a control of microprocessor. The microprocessor compares the definition values to control the focusing module to move the cam to a position where the projector may project a clear image on the screen.

Abstract: A lens device includes a main body unit, a guiding shaft unit, a lens unit, a focus adjusting unit and a resilient component. The guiding shaft unit includes three parallel guiding shafts disposed in the main body unit. The lens unit includes a lens frame disposed in the main body unit and having three guiding portions that receive slidably and respectively the guiding shafts, and a lens mounted co-movably in the lens frame. The focus adjusting unit is disposed in the main body unit and includes a driven member abutting against the lens frame and driven by a driving member for driving the lens unit to slide along the guiding shafts. The resilient component is disposed for biasing resiliently the lens frame toward the driven member.
