PROBLEM TO BE SOLVED: To provide a game machine for improving luminous efficiency of a light guide plate.SOLUTION: A pachinko game machine comprises a light emitting performance device 100 including: a light guide plate 110 for guiding light beams L1 and L2 made incident on an end face 111 forward to illuminate the light beams; and an LED light-emitting part 121 of an LED light-emitting board 120 in which light emission surface 122 of the light beams L1 and L2 for illumination of the light guide plate 110 are arranged to face the end face 111 of the light plate 110. Further, the game machine comprises shading cover members 130 and 140 for covering from the LED luminescent part 121 to the end part 112 of the side of the end face 111 of the light guide plate 110 and forming a light shielding space. On the inner faces of the shading cover members 130 and 140, there are formed the slope surfaces 131 and 141 which become reflection surfaces inclined so that the shading space S1 becomes narrower from the LED light-emitting part 121 side toward the end part 111 side of the light guide plate 110, and guide the light beam L2 to the end face 111. |
