If the intensity of the light is the same as the intensity of the second light before it is diffused, the intensity of the second light entering the fifth and sixth regions 650c, 650d will be the second and third regions 640c, 640d. Stronger than the first light entering. Therefore, the fifth and sixth regions 650c and 650d of the second diffusion member 650 are brighter than the second and third regions 640d of the first diffusion member 640.

In this way, the first light and the second light repeatedly reflect and diffuse at the inner surface of the recess R and the second casing 612, a part of the light advances toward the transmission member 612a, and the other part gradually attenuates. do. Since the first diffusion member 640 and the second diffusion member 650 are curved as described above, more light is emitted as compared with the case where the first diffusion member 640 and the second diffusion member 650 are not curved. It is diffused toward the transmission member 612a. Further, since the inner surface 611b of the rear side wall 611a is curved as described above, the light diffused by the second diffusion member 650 is transmitted to the transmission member 612a as compared with the case where the inner surface 611b of the rear side wall 611a is not curved. More reflected towards.

The first light and the second light that have traveled toward the transmitting member 612a are refracted by the unevenness of the rear side surface 612a1 of the transmitting member 612a, enter the transmitting member 612a, and are emitted to the outside. As a result, the lamp device 600 emits light.

[Effect of embodiment]
(1) The first diffusing member 640 introduces the light of the LED 632 from the lower side surface 643, and the second diffusing member 650 introduces the light of the LED 632 from the lower side surface 653, and the degree of diffusing the light from the LED 632 increases as the distance from the LED 632 increases. Therefore, the side of each diffusing member 640, 650 near the LED 632 can sufficiently diffuse the light transmitted from the side close to the LED 632 while diffusing the light while transmitting the light from the LED 632 to the distant side. can. Therefore, since the diffusing members 640 and 650 can diffuse the light so as to suppress the unevenness of the brightness, the unevenness of the brightness of the lamp device 600 can be suppressed. Furthermore, the quality of the pachinko gaming machine 1 can be improved.
(2) Since the light from the LED 632 can be easily diffused by the concave portion R, the unevenness of the brightness of the diffusion members 640, 650 and the lamp device 600 can be easily suppressed.

(3) Since the number of the recesses R per unit area changes stepwise, the degree of light diffusion can be changed stepwise. Therefore, the unevenness of the brightness of the lamp device 600 can be easily suppressed.

(4) Since the lamp device 600 includes the first diffusion member 640 and the second diffusion member 650, the lamp device 600 includes only one of the first diffusion member 640 and the second diffusion member 650, as compared with the case where the lamp device 600 includes only one of the first diffusion member 640 and the second diffusion member 650. A sufficient brightness of 600 can be secured. Further, the gap S suppresses the degree of light diffusion of one of the first diffusion member 640 and the second diffusion member 650 from being affected by the other of the first diffusion member 640 and the second diffusion member 650. Therefore, unevenness in brightness of each diffusion member 640, 650 and thus the lamp device 600 can be accurately suppressed.
(5) Since the gap S is smaller on the side farther from the LED 632 than on the side closer to the LED 632, the light diffused from one of the first diffusion member 640 and the second diffusion member 650 is the first diffusion member 640 and the first diffusion member 640. 2 It penetrates more into the other of the diffusion member 650 and is further diffused. Therefore, since the brightness of each of the diffusion members 640 and 650 can be ensured on the side far from the LED 632, the unevenness of the brightness of each of the diffusion members 640 and 650 and the lamp device 600 can be suppressed.

(6) Since the degree of light diffusion in the first diffusion member 640 and the second diffusion member 650 is set to be different from each other, unevenness in brightness of the lamp device 600 can be suppressed more accurately.
(7) More light from the LED 632 is diffused toward the transmitting member 612a by the first diffusion member 640 and the second diffusion member 650 as compared with the case where the first diffusion member 640 and the second diffusion member 650 are not curved. Will be done. Therefore, it is possible to suppress unevenness in brightness while ensuring the brightness of the lamp device 600.
(8) When the inner surface 611b of the rear side wall 611a is curved, the light diffused by the second diffusion member 650 is directed toward the transmission member 612a as compared with the case where the inner surface 611b of the rear side wall 611a is not curved. It is reflected a lot. Therefore, it is possible to suppress unevenness in brightness while ensuring the brightness of the lamp device 600. The lamp device 700 also has the same effect as that of the lamp device 600 described above.
