<p>PROBLEM TO BE SOLVED: To provide a game machine having an illumination device, from which only a design part to be changed in accordance with a design change can be exchanged.SOLUTION: A diffusion lens 11 is constructed to comprise: a reflection member 30 having a front face reflection part 31 for diffusing and reflecting a light received from the back, to the front; and a design member 20 formed, on the front face attached removably to the front of the reflection member, with an arbitrary design member 21 and, on the back face, with a back face reflection part 22. A space part is formed between the front face reflection part 31 and the back face reflection part 21 so that the irradiation light of an LED 41 is caused to pass through the reflection member 30 and the design member 20 and to be diffused forward. Even if the design member 20 is replaced by another design member 20 having a design different from that of the design member 21, the LED 41 and the reflection member 30 can be used as they are.</p> |
