In the conventional front door 20 described above, the fluorescent lamp 43 for illuminating the pattern drawn on the entire surface of the upper panel 40 is arranged inside the upper panel plate 41 of the upper panel 40. However, the central portion of the upper panel plate 41 near the fluorescent lamp 43 is bright, and the upper and lower peripheral portions of the upper panel plate 41 are darker than the central portion. Therefore, since the illuminance on the upper panel plate 41 is different, there is a problem that, of the patterns displayed on the upper panel plate 41, the patterns displayed on the periphery of the upper panel plate 41 do not appear beautifully. .

Further, in order to eliminate the unevenness of illumination on the upper panel plate 41, the distance between the upper panel plate 41 and the fluorescent lamp 43 is widened, and the distance from the fluorescent lamp 43 to the center of the upper panel plate 41 and the fluorescent lamp are Although it has been attempted to reduce the difference between the distance from 43 to the periphery of the upper panel plate 41, increasing the distance between the upper panel plate 41 and the fluorescent lamp 43 increases the thickness of the front door 20. There were drawbacks and limitations.

Further, in order to make the lower panel 70 look beautiful as in the upper panel 40, it is desired to provide an illuminating device inside the lower panel plate 71. Since the medal return passage 22 and the medal payout device 34 are arranged and assembling the lighting device in a narrow space requires a lot of labor for designing and manufacturing the slot machine, it has been generally abandoned.

Therefore, the inventions according to claims 1 to 3 are made in view of the problems of the above-mentioned conventional techniques, and the purpose thereof is to increase the thickness of the front door.

1 to 3 show an embodiment of the present invention. FIG. 1 is a sectional view of an essential part of a front door of a slot machine, and FIG. 2 is a rear view of an essential part of the front door. Figure 3
Shows respective rear views of the main parts showing the lower side of the front door. In the figure, 10 is a slot machine, and 20 is its front door.

As shown in FIG. 1, the upper panel 40 of the front door 20 is disposed on the front side thereof, for example, an upper panel board 41 on which a pattern is printed from the back side, and the upper panel board 41 is illuminated from the back side. And a lighting device 90 for lighting. As shown in FIG. 1, the illumination device 90 includes a transparent plate 91 arranged on the back side of the upper panel plate 41 and a reflecting plate arranged on the back side of the transparent plate 91 on the back side and having the transparent plate 91 side as a mirror surface. 92 and the transparent plate
And a cold cathode fluorescent lamp 93 arranged at the end of 91.

The transparent plate 91 is composed of a thick plate made of acrylic, and more specifically, as shown in FIG. 1, it has a vertical width within a range that can be easily assembled inside the upper panel plate 41 of the upper panel 40. Is made larger so that the right and left sides can cover a required portion of the upper panel plate 41 in accordance with the length of the fluorescent lamp 93. Then, as shown in FIG. 1, irregular reflection printing 94 is applied to the back surface of the transparent plate 91, that is, the entire surface overlapping the reflection plate 92. Therefore, the light incident from the end of the transparent plate 91 is repeatedly reflected and refracted inside, diffusely reflected at the portion where the ink is printed, and emitted from the front surface and the back surface of the transparent plate 91.

Further, the printing density of the ink is determined by the fluorescent lamp 93
It increases as you move away from. This is to compensate for the fact that the luminous flux density decreases as the distance from the fluorescent lamp 93 increases, and the light emitted from the back surface decreases when the diffuse reflectance is constant. That is, by gradually increasing the diffuse reflectance as the distance from the fluorescent lamp 93 increases, the amount of light emitted from the surface of the transparent plate 91 per unit can be kept uniform.

The transparent plate 91 is not limited to the case where the surface facing the reflecting plate 92 is subjected to irregular reflection printing 94, and one surface of the transparent plate 91 is ground glass-like by grinding or chemical treatment. The transparent plate 91 described above can also be used. Further, as shown in FIG. 1, a reflective film 95 is formed on the other end of the transparent plate 91, which is separated from the fluorescent lamp 93, by a coating process such as aluminum vapor deposition. For this reason, light passing through the inside of the transparent plate 91 is reflected by the reflection film 95 and returns inside the transparent plate 91, so that leakage from the other end to the outside can be prevented.

The reflection plate 92 is made of a synthetic resin thin plate, and its surface is mirror-deposited by aluminum vapor deposition.
Then, in order to make the door 10 thinner, the reflector 92 is made transparent.
It is desirable to make it as a laminated board with 91. In this way, by using a laminated plate, handling at the time of assembly can be facilitated. The fluorescent lamp 93
Are arranged near the upper end of the upper panel plate 41, as shown in FIG. Further, the fluorescent lamp 93 is covered with a reflecting tube 96 having an inner surface as a mirror surface. And, the reflecting tube 96 has a transparent plate.
A slit having a width corresponding to the thickness of 91 is provided along the axial direction, and the end of the transparent plate 91 is abutted against this slit to fix the reflecting tube 96 and the transparent plate 91 to the upper lamp board 42.

In this embodiment, as shown in FIG. 1, a cold cathode fluorescent lamp 93 is arranged near the end of the upper panel 41, and the fluorescent lamp 93 is covered with a reflecting tube 96.
The light emitted from is reflected on the inner surface of the launch tube 64 and is entirely guided from the end of the transparent plate 91 to the inside of the transparent plate 91. Since the transparent plate 91 is a thick plate made of acrylic resin, almost all the light incident from the end of the transparent plate 91 is reflected by the front surface and the back surface of the transparent plate 91 and the opposite end parts are reflected. Head to. At this time, since the transparent plate 91 is provided with the irregular reflection printing 94 on one side of the transparent plate 91 as the irregular reflection surface, a part of the light which is repeatedly reflected and refracted inside the transparent plate 91 is a transparent plate subjected to the irregular reflection printing 94. When the light is reflected on the inner surface of 91, the reflection angle is disturbed with respect to the incident angle, and then the light is emitted to the outside of the transparent plate 91 without being reflected on the front plane of the transparent plate 91.
The other part of the light that faces the front of 20 and repeats reflection and refraction inside the transparent plate 91 leaks to the outside of the transparent plate 91 and is reflected because the inner surface of the transparent plate 91 is a diffuse reflection surface. You will face the board 92.

Since the reflecting plate 92 is provided inside the transparent plate 91, the light leaked from the surface of the transparent plate 91 on which the irregular reflection printing 94 is applied is reflected by the reflecting plate 92 and again inside the transparent plate 91. Most of this light is emitted from the front surface of the transparent plate 91 to the outside. In addition, the transparent plate 91 is incident on the inside of the transparent plate 91 from the end and is repeatedly reflected and refracted without being emitted from the front surface of the transparent plate 91 by the irregular reflection printing 94.
The light reaching the other end of the transparent plate 91 is returned to the inside of the transparent plate 91 by the reflection film 95 provided at the end of the transparent plate 91, and the light from the front surface of the transparent plate 91 is reflected and refracted again. It decays while releasing a part to the outside.

As described above, this embodiment is a cold cathode fluorescent lamp.
All the light from 93 is guided from the end of the transparent plate 91 to the inside of the transparent plate 91 by the reflecting tube 96, and this light is radiated from the front surface of the transparent plate 91 by the irregular reflection printing 94, thereby changing the size of the transparent plate 91. Can be a surface light source, the upper panel plate of the upper panel 40
By uniformly illuminating 41 from the inside, it is possible to illuminate a wide area of the upper panel plate 41 without unevenness in illuminance, and it is possible to make the pattern displayed on the upper panel 40 look beautiful.

A light-shielding plate is provided on the inner side of the peripheral portion of the upper panel plate 41 so that the wide area of the central portion of the upper panel 40 has a constant brightness and the peripheral portion of the upper panel 40 is protected from light. The part that emits light when viewed from above may have a constant brightness, and a brightness difference between the central part and the peripheral part may be clearly provided. Further, in the above-described embodiment, the horizontal width of the upper panel 40 is adjusted so that the horizontal width of the transparent plate 91 is adjusted to the length of the cold cathode fluorescent lamp 93 to lighten the main area near the center of the upper panel plate 41. Arranges the cold cathode fluorescent lamp 93 toward one side of the upper panel 40 and arranges it at the upper end, and the transparent plate 91 and the reflecting plate 92 combined with this cold cathode fluorescent lamp 93 have the upper and lower widths as the upper and lower widths of the upper panel plate 41. The upper panel plate 41 should be approximated.
The transparent plate 91 and the reflection plate 92 are provided with another transparent plate and a reflection plate on the inner side in a side portion where the transparent plate 91 and the reflection plate 92 are not arranged inside. In some cases, a cold cathode fluorescent lamp covered with a reflection tube is arranged, and two sets of lamps and a transparent plate illuminate almost the entire surface of the upper panel 40.

Fluorescent lamp 93, transparent plate 91 and reflector
The combination of 92 is a surface light source that illuminates a wide area without causing unevenness of illuminance, so that it can be provided close to the upper panel plate 41, and the door 10 can be made thin so as to enlarge the space inside the door 10. There is also an advantage that can be done. Therefore, in the lighting device 90 of the present embodiment, the flat plate thick transparent plate 91 and the thin reflective plate 92 are arranged inside the upper panel plate 41 so as to be in close contact with the upper panel plate 41. It is also possible, and by disposing the fluorescent lamp 93 in the peripheral portion such as the inner upper edge and the lower edge of the upper panel plate 41, it is possible to uniformly and brightly illuminate almost the entire surface of the upper panel plate 41. As shown in FIG. 3, a laminated plate in which a transparent plate 91 and a reflective plate 92 are combined is arranged inside the lower panel plate 71 of the lower panel 70 so as to be close to the lower panel plate 71. A transparent plate 91 and a reflecting plate are provided between the lower panel plate 71 and the medal return passage 22 so that the cold cathode fluorescent lamp 93 covered with the reflecting tube 96 is arranged.
92 can also be inserted.

That is, even in a narrow space inside the lower panel 70, the transparent plate 91 is provided inside the lower panel plate 71 of the lower panel 70.
The transparent plate 91 is provided with a reflecting plate 92 inside the transparent plate.
A cold cathode fluorescent lamp 93 is provided at the end of 91, and the cold cathode fluorescent lamp 93 is covered with a cylindrical reflecting tube 96 having an inner surface as a mirror surface.
The end of the transparent plate 91 is abutted against the slit provided in the reflection tube 96, and a reflective film 95 is formed at the end of the transparent plate 91 facing the end abutted with the slit of the transparent plate 91. The light of the fluorescent lamp 93 can be reflected from the front surface of the transparent plate 91 as an irregular reflection surface by performing irregular reflection printing 94 on the inner surface of 91.

Therefore, the lower panel 70, which has been difficult to illuminate a wide range with uniform illuminance, can be illuminated uniformly from the inside, and the pattern of the lower panel plate 71 can be made beautiful. In the embodiment shown in the drawings, the illuminating device 90 illuminates the upper panel 40 and the lower panel 70, respectively.
Not limited to this, only one of the upper panel 40 and the lower panel 70 may be illuminated, or only a part of either one may be illuminated, and further, the middle panel 50 and the operation panel 60 may be illuminated. You may illuminate a part.

When illuminating adjacent panels,
By arranging the cold cathode fluorescent lamp 93 of the lighting device 90 between both panels, a common cold cathode fluorescent lamp 93 can be used. For example, if the upper panel 40 and the middle panel 50,
By disposing one cold cathode fluorescent lamp 93 between the upper panel 40 and the middle panel 50, both panels 40, 50 can be illuminated at the same time. Also, the middle panel 50 and the operation panel 60,
Alternatively, if the operation panel 60 and the lower panel 70, the middle panel
One cold cathode fluorescent lamp 93 is provided between the operation panel 60 and the lower panel 70 between the operation panel 60 and the operation panel 60.
By arranging, it is possible to simultaneously illuminate both adjacent panels 50 and 60, 60 and 70.
