【Example】

 An embodiment of an LED light guide plate (hereinafter simply referred to as “LED light guide plate”) used in the pachislot machine of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing the LED light guide plate of the present embodiment. FIG. 2 is a cross-sectional view showing a vertical front view of FIG. 1, and FIG. 3 is a bottom view of the LED light guide plate of the present embodiment. In the figure, reference numeral 1 denotes the LED light guide plate of the present embodiment.

In the drawings, reference numeral 2 denotes a base. In this embodiment, the base is constituted by an elongated member formed of an acrylic resin.

As shown in FIGS. 2 and 3, a plurality of LED insertion holes 4 are formed at an arbitrary interval on the lower surface of the base. An LED is inserted and fixed in the LED insertion hole 4. In this embodiment, the LED insertion hole 4 has a cylindrical shape with a dome-shaped upper surface. In addition, the size of the LED insertion hole 4 corresponds to the size of the LED to be used, and may be any size that can sufficiently accommodate the LED to be used.

Next, as shown in FIG. 1, a columnar light guide 3 is continuously provided on the upper surface of the base 2 corresponding to the LED insertion hole 4. The upper surface of the light guide 3, that is, the surface 301 shown in light black in the figure is a visible surface.

In this embodiment, the light guide 3 is also made of acrylic resin, and the base 2 and the light guide 3 are formed integrally.

Then, blast processing is performed on the upper surface 301 of the light guide section 3, whereby the gloss of the upper surface 301 is erased, and as a result, the upper surface 301 is roughened. Therefore, in the case of using this embodiment, the light emitted from the LED in the LED insertion section 4 is diffused by the rough surface of the upper surface 301, and the entire upper surface 301 is uniformly distributed to the player. It looks as if it emits light, and as a result, the entire upper surface 301 becomes a visible surface.

As described above, according to the present embodiment, the entire upper surface 301 of the light guide section 3 can be uniformly illuminated, and as a result, the entire upper surface 301 can be made a visible surface, so that the visible surface can be enlarged. Therefore, the player can easily recognize the light emission of the LED without increasing the brightness of the LED, so that the power consumption can be reduced and the cost can be reduced.

Further, according to the present embodiment, since the light of the LED can be diffused and the entire upper surface 301 of the light guide 3 can be uniformly illuminated, the light of the LED directly stimulates the eyes of the player. As a result, even if the game is played for a long time, it is possible to prevent the eyes of the player from being tired by the light of the LED.

In FIG. 1, reference numeral 5 denotes a heat radiation groove for heat radiation. The heat radiation groove 5 is used to release the heat generated by the LED to the outside of the base 2.

Next, a description will be given of a method of using the LED light guide plate 1 of the present embodiment configured as described above. In FIG. 4, a plurality of LEDs 6 mounted on a substrate 7 are provided with the LED insertion holes 4. The LED light guide plate 1 of this embodiment is connected and fixed to the substrate 7 so as to be housed therein.

Thereafter, the board 7 is connected to a power source by a connector (not shown) or the like, and the board 7 is mounted at a predetermined location of the pachislot machine. In this embodiment, the substrate 7 is provided at a location indicated by reference numeral 8 in FIG. 5 and is used as a light emitting unit for notifying a game over or the like.

When the LED 6 emits light in this state, the upper surface 301 of the light guide 3 emits light, and the player can recognize a predetermined situation, for example, a game over. At this time, in the LED light guide plate of the present embodiment, as described above, the entire upper surface 301 of the light guide 3 can emit light uniformly, so that the entire upper surface 301 is a visible surface. Therefore, unlike the conventional LED light emitting unit, the viewing surface can be enlarged, and the player can easily recognize the light emission of the LED.

Further, in the present embodiment, only the visible surface 301, which is the upper surface of the light guide section 3, is subjected to blast processing so that only the visible surface 301 emits light. The light of the LEDs 6 does not leak to the side surface of the part 3 and the like, and therefore, for example, even when the adjacent LEDs 6 are LEDs 6 of different colors, the colors do not mix with each other.

In this embodiment, the case where a plurality of LEDs 6 are provided has been described. However, it is not necessary to provide a plurality of LEDs 6, and the visible surface 301 of the light guide 3 is subjected to blast processing. If so, the LED 6 may be used alone.

The shape of the light guide section 3 does not necessarily have to be a cylindrical shape, and may be any shape as long as the sighting surface 301 has been subjected to blast processing. Alternatively, the upper surface may be convex or concave, or the upper surface may be diamond cut.

Further, the base 2 and the light guide 3 do not necessarily need to be formed of an acrylic resin, and the base 2 and the light guide 3 do not need to be integrally formed.
