PROBLEM TO BE SOLVED: To provide a display lamp of an inter-machine dispenser for a game board emitting a light without any uneven brightness or irregular color using a light emitting diode as a light source. SOLUTION: A display lamp 5 for displaying operation is attached to the upper end of a front panel 4 of the inter-machine dispenser 1 for the game board. The display lamp 5 is provided with a cover lens plate 14 applied with a light diffusion function, a diffusion lens plate 13 disposed in its rear side, and a light emitting diode chip 11 disposed in its rear side. An interval between the lens body part 14b of the cover lens plate 14 and the diffusion lens body part 13c of the diffusion lens plate 13 is set to approximately fixed in every part. After the light emitted from the light emitting diode chip 11 is diffused via the diffusion lens plate 13, it lights the lens body part 14b of the cover lens plate 14 at a equal distance from the diffusion lens body part 13c from the rear side. As a result, the surface of the lens body part 14b of the cover lens plate 14 is lit at a uniform brightness without any irregular color. COPYRIGHT: (C)2005,JPO&NCIPI
