PROBLEM TO BE SOLVED: To provide a decoration device, an illumination unit, an illumination device, and a Pachinko game machine, which enable the lighting of illumination symbols with no variations in quantity of light to facilitate the visual recognition from ahead by arranging LEDs as spot light sources to ensure a sufficient quantity of light though used in minimum necessary numbers and furthermore, can reduce the working procedure of a game board. SOLUTION: A decoration component with light-transmitting holes 30 and 31 so formed as to be bored in the surface of the game board along the periphery of a central opening part 4 includes: a light-permeable plate 36 fixed on a center member 10 while being arrayed in front of the light-permeable holes; light-transmitting picture films 40 each having a plurality of picture patterns 41 drawn in proximity to each other in corresponding areas within the light-transmitting holes; light diffusively transmitting films 45 respectively arrayed within the ranges corresponding to the picture patterns; concave lens plates 50 for light diffusion respectively arrayed within the ranges corresponding to the picture patterns; and a light-shielding circular partition 51 protrusively arranged on the backside along the outer peripheral contour of each of the concave lens plates. The plurality of circular partitions is contained within the corresponding range in one light transmitting hole. COPYRIGHT: (C)2008,JPO&INPIT
