ABSTRACT:
A display unit is provided capable of reducing the generation of heat due to a light source. There are provided a light source lamp, light dividing mirrors for dividing incident light emitted by the light source lamp, and a plurality of projector units capable of modulating the divided incident light to incident light and projecting the incident light to game boards to display images. With such an arrangement, images can be displayed on a plurality of game machines with the single light source lamp, and thus the number of light sources can be reduced in the entire game system, which reduces the entire amount of heat generated by the light source lamp.
