Abstract

A projector, including a body, a light source, a light valve, a projection lens, and a lens adjustment module, is provided. The light source and the light valve are disposed in the body, and the projection lens is movably disposed on the body. The lens adjustment module includes a driven structure connected to the projection lens, a guiding member and a rotating member connected to the guiding member. The guiding member is disposed on the body to be rotatable along an axis of rotation and has a closed ring guiding rail. The driven structure is slidably disposed at the closed ring guiding rail and is configured to move relative to the guiding member along a closed ring path defined by the closed ring guiding rail. A normal direction of a surface where the closed ring path is located is not parallel to the axis of rotation.
