As shown in reproduction 1.9 to 1.29, the design has a lens at the top part of the main body and a reflector at the inside of the top cover, so that the screen can be projected to the front or ceiling according to the angle of the top cover, and also can adjust the height of the projected screen. This design has a cable auto loader and storage box at the bottom of the rear side, so user can store the cables, media storage or remote controls in the box.
