    • A belly door for a gaming machine includes a frame for receiving a sheet of artwork and a light reflective chamber having an open face which is located behind the frame when in a closed position. Clamping means are provided for clamping the artwork between the frame and the chamber. A recess extends along one edge of the chamber including sockets for receiving a fluorescent light tube when the chamber is in the closed position. A diffuser panel is disposed in the chamber behind the artwork located so as to be edge lit by the fluorescent light tube. The reverse face of the panel, which in use, faces the rear wall of the chamber defines a series of white opaque dots which in use, diffuse and direct the light in a forward direction perpendicular to the plane of the panel. The size of the dots in the panel increases with the distance of the dots from the fluorescent light tube. This arrangement ensures that the light panel produces a very evenly balanced lighting of the artwork.
    • 用于游戏机的腹部门包括用于接收一张艺术品的框架和在处于关闭位置时位于框架后面的具有开放面的光反射室。 提供夹紧装置用于在图案和框架之间夹紧图案。 凹部沿着腔室的一个边缘延伸,包括用于当腔室处于关闭位置时用于接收荧光灯管的插座。 扩散板设置在艺术品后面的室中,以便被荧光灯管边缘点亮。 在使用中面向腔室后壁的面板的相反面限定了一系列白色不透明点,其在使用中扩散并引导垂直于面板平面的向前方向的光。 面板上的点的大小随着点与荧光灯管的距离而增加。 这种布置确保了照明面板产生了非常均匀的艺术作品照明。
