PROBLEM TO BE SOLVED: To provide a Pachinko machine with a stable quality in which the occurrence of brightness difference due to the bend of an LED is eliminated. SOLUTION: The LEDs (light emitting diods) 15 and a lens 22' for the LEDs are soldered to a printed circuit board 20'. On the upper surface of the lens 22' for the LEDs, protruding parts 24 are formed at positions respectively corresponding to the LEDs 15. On the lower surface of the lens 22' for the LEDs, a recessed part 35 for accommodating the LEDs 15 is formed. In the recessed part 35, recessed parts 36 for determining the directions of the LEDs 15 are formed at positions corresponding to the protruding parts 24. The depth (h) of the recessed part 35 is smaller than the height of the soldered LED 15. A part of each LED 15 accommodated in the recessed part 35 is inserted into the recessed part 36 formed in the recessed part 35. The directions of the LEDs 15 are fixed in the directions where the recessed parts 36 are formed. COPYRIGHT: (C)2004,JPO
