PURPOSE: A manual guide vehicle is provided to remove particle contamination and operator's viewing hindrance by LCD(Liquid crystal display) glass when moving a cassette in which the LCD glasses are received. CONSTITUTION: The vehicle comprises: a case(204) having a hexahedron structure in which an upper face is wholly opened and a lower face is partially opened; a stay(230) on which LCD glasses are mounted and installed in the case; a moving unit(210) for moving the stay upward or downward within the case, the moving unit being coupled by screws to through holes formed at four corners of the stay; a power supplying unit for supplying an electric power to drive the moving unit; and a controller for controlling the power supplying unit. Thus, the case of the vehicle has openings at upper and lower faces thereof, which allow clean air to be introduced and extracted, thereby minimizing the contamination due to generation of particles. |
