  • PROJECTING APPARATUS
    Publication number: 20120249975
    Abstract: A projecting apparatus for protecting an image onto a screen includes an image module, a first light reflection device and a lens. The image module is for providing a beam of first light, The first light reflection device has a first reflection surface disposed movably relative to the image module for reflecting the first light to form a beam of second light. The lens is for projection the image on the screen according to the second light. Moving the first light reflection device along the beam of first light or second light can adjust the location of the image on the screen in a first direction.

  • PROJECTOR AND METHOD FOR ASSEMBLY THEREOF
    Publication number: 20040223124
    Abstract: The projector includes an image modulator, a lens, a supporting frame for supporting the image modulator and the lens, a circuit board, and a frame. The supporting frame includes a first fixed side, a second fixed side, and at least one elastic protrusion having one end connected to the first fixed side, and another end having a gap with the second fixed side. The method utilizes the elastic protrusion of the supporting frame to adjust relative positions of the image modulator and the lens to optimize the focus of the lens.
