In particular, the panel unit 6 has a characteristic configuration for efficiently irradiating light from the LED 671 to the entire panel with uniform brightness.
Hereinafter, the panel unit 6 will be described.

[Panel section]
FIG. 4 is an exploded perspective view of the panel unit of the present embodiment, and FIG. 5 is a front view and a cross-sectional view of the panel unit. 6 to 9 are a hexahedral view and a perspective view of each component of the panel. Moreover, FIGS. 10-12 is a figure which shows the various aspects of a panel part.
As shown in FIGS. 4 and 5, the panel unit 6 of the present embodiment includes an LED substrate 67 (light source unit) having a plurality of LEDs 671 (point light sources) in a lower panel recess 69 at the lower part of the operation unit 4, and LED An illumination light diffusion cover 66 (diffusion cover) that covers the front side of the substrate 67 and diffuses the irradiation light from the LED 671, a panel 60 including a front panel 62, a pattern sheet 63, a sheet sheet 64, and a rear panel 65; A panel frame 61.

Among these, the illumination light diffusion cover 66 is disposed between the rear panel 65 and the LED substrate 67 and is disposed at a predetermined interval from the rear panel 65 (see FIG. 5B). ). For example, the illumination light diffusion cover 66 of the present embodiment has a surface (convex surface) 662 that is separated from the rear panel surface 658 of the rear panel 65 by about 15 mm.
In this way, the light diffused by the illumination light diffusion cover 66 can be further diffused before reaching the panel 60.
Further, the illumination light diffusion cover 66 has a concave shape (in the present embodiment, a tray shape), and the concave portion is arranged facing the light source side.
For this reason, the light irradiated to the panel 60 side from the illumination light diffusion cover 66 is emitted widely based on the shape.
Hereinafter, each structure of the panel part 6 is demonstrated in detail.

(LED)
The LED 671 is a point light source with high directivity, and is known as a light source with a narrow irradiation area.
In the present embodiment, such an LED 671 is used as a light source for irradiating the panel 60.
Specifically, a plurality of LEDs 671 are arranged in a straight line on a long LED substrate 67 and provided in a plurality of rows.
The LED board 67 can illuminate the panel 60 from the back side by attaching it to the mounting plate 68 (mounting base 681) with the irradiation part facing the front side (FIG. 5B, FIG. 10). Etc.).
In the present embodiment, the two LED boards 67 are attached to the attachment plate 68 in parallel in the vertical direction. However, the number of LED boards 67 is not limited to two, and may be one or three or more.
Moreover, the aspect which attaches along the said arrangement | sequence may be sufficient as the rod-shaped light source manufactured by putting several LED671 into a tube.
Moreover, LED671 simple substance can also be attached individually.

(Lighting diffuser cover)
The illumination light diffusion cover 66 is a diffusion member for diffusing light, and is installed between the LED substrate 67 and the panel 60 so that the panel 60 has a uniform brightness via the illumination light diffusion cover 66. It will be irradiated.
The illumination light diffusing cover 66 is a milky white translucent in which a predetermined inorganic particle or organic fine particle diffusing agent is blended in a resin such as ABS (Acrylonitrile Butadiene Styrene) or polycarbonate, and this is molded to a certain thickness. The resin plate is used.

In particular, the illumination light diffusion cover 66 of the present embodiment has a tray-like shape, and includes a rectangular flat bottom that is smaller than the panel surface, and a peripheral edge 664 whose peripheral edge is round (curved).
As shown in FIGS. 4 and 5, the illumination light diffusion cover 66 has a bottom surface (concave surface) 663 facing the LED 671 side, and upper and lower mounting ears 661 are screwed to mounting holes (not shown) of the mounting plate 68. Attach (see FIGS. 9-11).
Moreover, the illumination light diffusion cover 66 of this embodiment is attached so that the LED 671 is arranged in the vicinity of the opening boundary surface on the back surface (concave surface) 663 side (see FIG. 5B).

In this case, since the LED 671 and the illumination light diffusion cover 66 are arranged at an interval, a low directional component (that is, light emitted in an oblique direction from the LED 671) out of the light emitted from the LED 671 is diffused light. Can be incorporated efficiently.
However, if the distance between the LED 671 and the illumination light diffusion cover 66 is too large, the illuminance is significantly reduced.
For this reason, the illumination light diffusion cover 66 is preferably attached so that the distance from the LED 671 is appropriate (for example, about 12 mm) in consideration of these balances.

In addition, when the illumination light diffusion cover 66 of this embodiment is attached to the attachment plate 68, the upper LED board 67 is arranged in the vicinity of the upper peripheral edge 664 (FIGS. 5B and 11). reference).
For this reason, the incident light from the LED 671 can be diffused to the corners of the upper peripheral edge 664 without attenuation, and the light can be irradiated more widely in the upper direction of the panel 60.
In this way, an illumination light diffusion cover 66 smaller than the panel 60 can be used, and the panel 60 can be efficiently irradiated with a small number of light sources, corresponding to such a compact illumination light diffusion cover 66.
Further, as shown in FIG. 5B, the illumination light diffusion cover 66 can be attached so as to face obliquely upward.
In this way, a space can be created between the lower peripheral edge 664 of the illumination light diffusion cover 66 and the mounting plate 68.
For this reason, the heat | fever emitted from LED671 can be discharge | released outside through this space.

Next, the diffusion of light in the illumination light diffusion cover will be described with reference to FIG.
As shown in FIG. 13, when the irradiation light from each LED 671 installed on the LED substrate 67 is incident from the back surface of the illumination light diffusion cover 66, except for a part, it collides with the diffusing agent scattered inside the cover. This refracts and diffuses in an unspecified direction.

A part of the diffused light is emitted to the outside from a boundary surface between the surface of the illumination light diffusion cover 66 and the external space (hereinafter referred to as a boundary surface), and the other part is reflected from the boundary surface and each diffusing agent. It propagates toward the peripheral portion 664 while repeating the diffusion due to the collision.
The light reaching the peripheral edge 664 is further propagated along the round boundary surface toward the end of the peripheral edge 664 while repeating reflection and the like. Among them, the incident angle is small (nearly perpendicular to the boundary surface). ) Light is emitted in the normal direction of the interface.
As a result, light is emitted radially from the boundary surface of the peripheral edge 664 along the round curved surface.
Therefore, the entire panel 60 can be efficiently and uniformly irradiated.

(panel)
As shown in FIGS. 4 and 5 and the like, the panel 60 has a predetermined character and a picture printed on a transparent sheet between a transparent rear panel 65 and a front panel 62, and a predetermined crease process on a part thereof. It is configured by sandwiching a pattern sheet 63 subjected to. In addition, if necessary, the entire surface of the transparent sheet is subjected to crease processing, and the crease sheet 64 is overlapped with the pattern sheet 63 and used.

  As shown in FIGS. 6 and 7 and the like, the front panel 62 and the rear panel 65 are similar concave shapes, and the front convex portion (rear side) of the rear panel 65 is formed on the rear surface concave portion (front panel surface 627) of the front panel 62. By overlapping the side panel surface 658), the protrusions 652 of the upper side 651 of the rear panel 65 are locked in the locking holes 622 of the upper side 621 of the front panel 62, and the lower side of the front panel 62 The lower side locking claws 656 of the lower side portion 655 of the rear panel 65 are locked in the locking holes 625 provided in the locking pieces 624 of the portion 623, whereby the front panel 62 and the rear panel 65 are connected. Integrated.

The lower panel frame 61 is a frame attached to the periphery of the panel 60 as shown in FIG.
As shown in FIG. 8, fixed bosses 613 corresponding to the notches 626 of the front panel 62 and the screw holes 657 of the rear panel 65 are provided at the four corners of the back surface of the lower panel frame 61.
For this reason, in a state where the front panel 62 and the rear panel 65 are integrated, the lower panel frame 61 is fitted to the peripheral edge of the front panel 62 and is screwed from each screw hole 657 of the rear panel 65. The lower panel frame 61 is integrated.

In this state, each locking projection piece 611 of the lower panel frame 61 is locked to each locking hole 692 (see FIG. 11) provided in the lower part of the lower panel recess 69 of the front door 1a, while the rear side The panel 60 is temporarily fixed to the lower panel recess 69 of the front door 1a by locking the upper edge locking claw 653 of the panel 65 in the locking hole 691 provided in the upper portion of the lower panel recess 69 of the front door 1a. The
And a panel part 6 is fixed to the lower part of the front door 1a by passing a screw from the back side of the front door 1a to a mounting hole (not shown) of the mounting plate 68 and screwing to a fixing boss 654 of the rear panel 65 ( (See FIG. 12).
An avoidance notch 612 for avoiding interference with equipment in the front door 1a is provided on the upper side of the lower panel frame 61.

In this way, the panel 60 is detachably attached to the front door 1a, with the pattern sheet 63 and the transparent front panel 62 and the rear panel 65 sandwiching the pattern sheet 63 from the front and the rear in a separable manner.
For this reason, it is possible to take out only the unitized panel 60 and replace the pattern sheet 63 without replacing the entire panel unit 6, thereby changing the display contents. That is, generalization is achieved so that it can be changed to a different model by exchanging the pattern sheet 63.

By the way, even if the illumination light diffusion cover 66 has a small content of the diffusing agent or when the brightness of the LED 671 is high, display of granular light on the panel 60 may not be avoided.
In such a case, it can be made inconspicuous by increasing the content of the diffusing agent or decreasing the luminance of the LED 671.
However, the content of the diffusing agent cannot be adjusted after the illumination light diffusing cover 66 is manufactured, and the brightness of the panel 60 as a whole may be insufficient due to the adjustment that lowers the luminance of the LED 671.
Therefore, in the present embodiment, by using the pattern sheet 63 and the itch sheet 64 that have been subjected to the squeezing process, by utilizing the irregular reflection of light on the unevenness applied to these surfaces, the granular light can be obtained without performing the above adjustment. This makes it possible to obtain a unique visual effect.
Hereinafter, such a pattern sheet 63 will be described.

  The pattern sheet 63 is printed with a desired color on the surface of a substrate such as a resin-made transparent sheet by a silk printing method or the like in a desired color. It can be generated by carrying out a punching process (printing). Note that “chimi” refers to a hook-like pattern.

In the fringing process, first, a white ink having a high light diffusibility is printed except for an area (a fringing area) that causes a visual effect by the processing.
Next, in the process of printing a transparent (or opaque) special ink for frying printing on the fringing area and then drying it by irradiating with ultraviolet rays, by adjusting the drying time, To form. Note that, as in the present embodiment, special ink may be printed on the entire surface of the sheet including the pinching area (see FIG. 14).
As a result, as shown in FIG. 14A, a base layer 631 corresponding to a resin sheet as a base material, a pattern layer 632 printed with a design such as a pattern, and a white ink layer 633 printed with white ink Then, a pattern sheet 63 having a laminated structure including the uneven layer 634 obtained by the above-described bending process is generated.

When the pattern sheet 63 is irradiated with high-intensity light from the back side, the light irregularly reflected by the uneven layer 634 passes through the base layer 631 in the region (A region) where the white ink layer 633 is not laminated. Appear on the surface of the panel 60.
On the other hand, in the region (B region) where the white ink layer 633 is laminated, the irregularly reflected light does not pass through the white ink layer 633, and the light is diffused throughout the region by the light diffusion function of the white ink.
For this reason, the entire area of the white ink layer 633 is irradiated with uniform brightness, and the squeak area has a visual effect in which high-intensity light is irregularly reflected and glaringly displayed.

Next, the visual effect will be described with reference to FIG.
In addition, as shown in FIG. 14, the area | region where the white ink layer 633 is not given to the back surface among the area | regions where the pattern layer 632 was given is set to A area | region, and the area | region where the white ink layer 633 is given to the back surface Let B area.
In addition, when the panel 60 is attached, the composition of the pattern and the position of the LED substrate 67 are adjusted so that the arrangement of the area A and the LED 671 coincides. That is, it is set so that light with high luminance and high directivity reaches the area A and granular light is easily generated.

In FIG. 14A, first, light emitted from the LED 671 is diffused when entering the illumination light diffusion cover 66, and the diffused light passes through the rear panel 65 and reaches the back surface of the pattern sheet 63. However, high brightness light reaches the back surface of the pattern sheet 63 in a portion corresponding to the position of the LED 671 as in the area A.
The light reaching the back surface of the pattern sheet 63 is irregularly reflected by the uneven layer 634.
Among these, in the area A where the white ink layer 633 is not laminated, the base layer 631 is transmitted and reaches the pattern layer 632.
For this reason, in the A region, a high-luminance light from the LED 671 has a visual effect that glitters due to irregular reflection, and such a visual effect makes granular light inconspicuous.

On the other hand, in the B region where the white ink layer 633 is laminated, light diffuses in the B region by the white ink diffusion function.
For this reason, in the B region, the light diffused by the illumination light diffusion cover 66 is further diffused by the function of the color ink.
As a result, the granular light is not conspicuous even in the B region, and the light is more uniformly irradiated, so that the visual effect in the A region can be enhanced by the contrast between the A region and the B region.

Next, the squeezing sheet 64 that has been subjected to squeezing processing will be described.
The pinching sheet 64 is produced by laminating a base layer 641 corresponding to a resin sheet as a base material and an uneven layer 642 by the pinching process (see FIG. 14B).
For example, in the case where it is not possible to prevent the generation of granular light only by the visual effect due to the bending process of the pattern sheet 63, the sheet sheet 64 can be eliminated by using the sheet 64 together with the pattern sheet 63.
Specifically, the itch sheet 64 and the pattern sheet 63 are sandwiched between the front panel 62 and the rear panel 65 so that the pattern sheet 63 is on the front side (FIGS. 4 and 14 (b)). )reference).

In FIG. 14B, first, light emitted from the LED 671 is diffused when entering the illumination light diffusion cover 66, and the diffused light passes through the rear panel 65 and reaches the back surface of the sheet 64. However, high brightness light reaches the back surface of the sheet 64 in a portion corresponding to the position of the LED 671 as in the area A.
The light that has reached the back surface of the sheet sheet 64 is irregularly reflected by the uneven layer 642, passes through the base layer 641, and reaches the back surface of the pattern sheet 63.
Among these, in the area A where the white ink layer 633 is not laminated, the base layer 631 is transmitted and reaches the pattern layer 632.
For this reason, in the A region, high-brightness irregularly reflected light is further irregularly reflected by the uneven layer 634, and as a result, the glittering light is more precisely shining, and the granular light becomes less noticeable due to such a visual effect.

That is, by using the pattern sheet 63 and the itch sheet 64 together, it is possible to make the area A shine with more precise light than when only the pattern sheet 63 is used. The light can be made less noticeable.
In addition, about B area | region, since there exists an effect substantially the same as the case where the pattern sheet 63 is used independently, it abbreviate | omits about specific description.

As described above, it is possible to obtain a unique visual effect by applying the squeezing process to the pattern sheet 63 and to adjust the visual effect depending on whether or not the squeeze sheet 64 is used together. Yes.
Such adjustment of the visual effect can be performed only by using the pattern sheet 63 by changing the degree of unevenness (such as the density of the unevenness) in the patterning process in the pattern sheet 63 without using the index sheet 64. .
However, the pattern sheet 63 is printed with a pattern by silk printing or the like, and is more expensive than the sheet sheet 64 that is simply subjected to the sheet processing.
For this reason, the desired visual effect can be obtained at low cost by using the massaging sheet 64 in combination.

As described above, according to the gaming machine of the present invention, by attaching the illumination light diffusion cover 66 to a predetermined position on the back side of the panel 60, light from a light source having a narrow irradiation area such as an LED (point light source) can be effectively obtained. Since it can be diffused, the entire panel can be illuminated with uniform brightness.
In addition, by using irregular reflection of irregularities applied to the pattern sheet 63 or the like, a unique visual effect can be achieved so that granular light cannot be visually recognized.
In addition, such visual effects can be adjusted at low cost by using the kneading sheet 64 after the kneading process.

Furthermore, it is possible to easily detect an illegal act performed through the panel unit 6 by uniformly irradiating the entire surface of the panel as in the present embodiment and enabling display with uniform brightness. .
For example, there is an illegal act that makes a game advantageous by opening a through hole reaching an attachment plate 68 in an arbitrary region of the front panel 62 using a tool such as a drill and changing a game signal using a lead wire or the like. In this case, the high-intensity irradiation light from the LED 671 leaks from the hole of the illumination light diffusion cover 66 and is projected onto a part of the pattern sheet 63.
For this reason, the store clerk can easily find fraud based on such an unnatural projection.

The preferred embodiment of the gaming machine of the present invention has been described above, but the gaming machine according to the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the present invention. Needless to say.
For example, the itch sheet 64 may be directly attached to the pattern sheet 63.
Further, in the above embodiment, the pattern sheet 63 and the itch sheet 64 are subjected to the squeezing process, but only the pattern sheet 63 subjected to the squeeze process may be used, or the pattern sheet 63 that is not subjected to the squeeze process. The present invention can also be configured by combining the torch paper sheet 64.
Further, it is also possible to apply a kneading process to either or both of the front panel 62 and the rear panel 65 constituting the panel 60.
Moreover, although the said embodiment demonstrated the example which arranged LED671 (LED board | substrate 67) which is a point light source on the attachment board 68, it is not restricted to a point light source, For example, a short rod-shaped light source is arranged on the attachment board 68 intermittently. It is also possible to use this mode.
Even in this case, the light from the rod-shaped light source is effectively diffused by the illumination light diffusion cover 66, and the entire panel can be irradiated with uniform brightness.

  The present invention can be suitably used for a slot machine (rotating game machine) having a panel portion.
