PURPOSE: A wheel device for a projector is provided to move a projector to a desired position on a flat surface. CONSTITUTION: A wheel device(200) is combined with the bottom surface of a projector(100). In controlling an image by projecting beam on a screen, the desired direction is easily moved by pushing the projector. Each wheel has a longish shape and is contacted with a surface not to change the forward direction with light external force such as vibration. Thus, the projector goes straight in a regular direction and then settles by stopping rotating the wheel. |
