Description

  The present invention relates to a gaming machine such as a slot machine or a pachinko gaming machine, and more particularly to a gaming machine using a light emitting panel (EL light emitting panel) as a display device (display).

  In a gaming machine such as a pachinko gaming machine, a game board is decorated (electrical decoration) that defines a game area by light effects. In such a gaming machine, there is one that uses a thin sheet of electroluminescence (EL) to decorate the game board, and the EL sheet can be applied by applying a voltage to the EL element. In addition to being light-emitting, thin, lightweight, easy to install and inexpensive, various lighting displays can be performed by controlling the lighting pattern by a computer or the like.

  In general, an EL sheet is a laminate in which a back protective layer, a back electrode layer, a dielectric layer, a light emitting layer, a transparent electrode layer, and a surface protective layer are sequentially laminated. Each has insulation and water barrier properties, and surrounds the back electrode layer, the dielectric layer, the light emitter layer, and the transparent electrode layer.

Further, a light-emitting panel is known by laminating a light-transmitting decorative sheet (decorative layer) on at least a part of the above-described EL sheet surface protective layer via a transparent adhesive layer (for example, a patent) Reference 1 and 2).
Japanese Patent No. 2723177 Japanese Patent No. 2799966

  By the way, in the light emission panel of patent document 1 and 2, since two layers, a surface protective layer and a transparent adhesive layer, are interposed between the transparent electrode of the EL sheet and the decorative layer, the surface protective layer and Even if the transparent adhesive layer is light transmissive, irregular reflection of light is likely to occur in these two layers, resulting in a decrease in luminance.

  In addition, in the light-emitting panels described in Patent Documents 1 and 2, deformation such as bending is likely to occur due to the material characteristics, and the work is troublesome when attached to a decorative item such as a gaming machine.

  That is, when the light-emitting panels described in Patent Documents 1 and 2 are used for electrical decoration (light-emitting display) of gaming machines, there is a problem that irregular reflection of light easily occurs and it is difficult to perform a good light-emitting display.

  Further, in the pachinko game machine, a large number of nails for guiding the pachinko balls are struck on the game board surface, and these nails inevitably penetrate the light emitting panel and are nailed to the substrate. As a result, the nail contacts the two transparent electrode layers and further contacts the back electrode layer. Although the surface of the nail is generally insulated, there is a problem that when the insulation is deteriorated, the transparent electrode layer comes into contact with the back electrode layer through the nail to cause a short circuit. .

  Accordingly, an object of the present invention is to provide a gaming machine which can be easily attached and can perform a light emitting display.

Therefore, there is an effect that it is easy to form the nail hole.

  Hereinafter, gaming machines according to embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a diagram showing an example of a game board of a pachinko gaming machine. A front panel 12 is fitted on the front surface of the exterior frame 11 of the pachinko gaming machine, and an EL light-emitting panel described later is disposed on the front panel 12. A transparent substrate such as glass or acrylic resin is used for the front panel 12. And in the front panel 12, the translucent part 12a is arrange | positioned in the position which arrange | positions an EL light emission panel. Various decorative items 12b such as a liquid crystal panel are disposed on the front panel 12 other than the light transmitting portion 12a. Therefore, since the front panel 12 is substantially composed of an EL light-emitting panel and a liquid crystal panel, the pachinko gaming machine provided with the front panel 12 can produce a powerful effect that has not existed before. Further, the front panel 12 is provided with a plurality of nails 42 and a windmill described later.

  Here, referring to FIG. 2, FIG. 2A is a perspective view showing an example of the EL light emitting panel 20 in an exploded state, and FIG. 2B is a view showing an example of the EL light emitting panel 20 in a stacked state. It is. The EL light emitting panel 20 has a structure in which an EL light emitting element 21, a binder layer 22, a decorative layer 23 that also functions as a display layer, and a panel base material 24 are sequentially laminated and integrated. The EL light emitting device 21 has a structure in which, for example, a back protective layer 21a, a back electrode 21b, a dielectric layer 21c, a light emitting layer 21d, and a transparent electrode 21e are sequentially stacked by printing.

  The back protective layer 21a is made of, for example, medium, and the back electrode 21b is made of, for example, carbon and resin binder ink. Furthermore, the dielectric layer 21c is made of, for example, barium titanate and a fluororesin binder ink, and the light emitter layer 21d is made of, for example, zinc sulfide, copper, and a fluororesin binder ink. The transparent electrode 21e is made of indium tin oxide (ITO), for example.

  As illustrated, the back protective layer 21a is formed with two through holes 21f and 21g on the outer surface of the back protective layer 21a for opening the back electrode 21b and the transparent electrode 21e. The back electrode 21b, the dielectric layer 21c, and the light emitting layer 21d are formed with through holes 21g for exposing the transparent electrode 21e on the outer surface of the back protective layer 21a.

  On the other hand, the binder layer 22 has adhesiveness that exerts an adhesive force on both the transparent electrode 21e and the decorative layer 23 (ink layer 23c) of the EL light emitting element 21, and the light emitting layer 21d of the EL light emitting element 21. It has light transmissivity to transmit emitted light. This adhesiveness mainly exhibits an adhesive force due to the close contact due to leveling (flatness) on both the transparent electrode 21e and the decorative layer 23.

  In the illustrated example, since the EL light emitting element 21 does not include a surface protective layer, the binder layer 22 desirably has an insulating property and a water barrier property as necessary. The water barrier property is necessary to prevent the deterioration of zinc sulfide in the light emitting layer 21d of the EL light emitting element 21.

  The decorative layer 23 is obtained by laminating ink layers 23b and 23c on both sides of a single layer of metal foil layer 23a such as aluminum by printing or foil pressing using the panel base 24 as a base. The decoration layer 23 is a highly sophisticated decoration by selectively combining light transmission and light blocking (light non-transmission) with the metal foil layer 23a to give the two ink layers 23b and 23c decoration such as multicoloring. It has the property (design property).

  The panel substrate 24 is used to protect the shape and prevent deformation, and is formed from a sheet or plate such as acrylic or polycarbonate. When the EL light emitting panel 20 shown in FIG. 2 is produced, a binder layer 22 is laminated on the decorative layer 23 laminated on the panel base material 24 by printing or the like, and the separately produced EL light emitting element 21 is transparent. The electrode 21e is bonded to the binder layer 22 and laminated.

  In general, when shipping as a product, the adhesive adhesive layer 25 is laminated on the outer surface of the back protective layer 21a of the EL light emitting element 21, and a release sheet (not shown) is further laminated as necessary. Also for the adhesive bonding layer 25, through holes 25a and 25b corresponding to the through holes 21f and 21g of the EL light emitting element 21 are formed.

  As described above, in the EL light-emitting panel 20 shown in FIG. 2, since the single-layer binder layer 22 is interposed between the transparent electrode 21e of the EL light-emitting element 21 and the decorative layer 23, irregular reflection of light. Is prevented and the luminance can be improved.

  Here, referring to FIG. 3, FIG. 3A is a perspective view showing a state before the above-described EL light emitting panel 20 is attached to the article to be decorated 30, and FIG. It is a perspective view which shows the state after attaching the light emission panel 20. FIG. In the illustrated example, the decorative article 30 has an inverter 32 connected to a power source (external power source) 31, and a pair of electrodes 33 connected to the inverter 32 is formed on the mounting surface of the decorative article 30. Yes.

  When the EL light emitting panel 20 is attached to the decorative article 30, the release sheet is peeled off from the EL light emitting panel 20, and the adhesive bonding layer 25 is exposed. And it attaches by sticking EL light emission panel 20 on the attachment surface of to-be-decorated goods 30 with the adhesive bonding layer 25. FIG. At this time, the electrode 33 and the through holes 25a and 25b are connected.

  Since the through-hole structure is used in this way, the EL light emitting element 21 (that is, the back electrode 21b and the transparent electrode 21e) can be connected to the power source 31 very easily.

  As described above, since the EL light-emitting panel 20 has the panel base material 24, the entire shape of the EL light-emitting panel 20 is maintained upon attachment, and the shape of the EL light-emitting panel 20 is bent. There is no, and attachment work can be performed easily. As shown in FIG. 4, the attachment surface of the article to be decorated 30 may be formed into a groove shape, and the attachment surface may be fitted into the EL light emitting panel 20.

  Next, another example of the EL light emitting panel used in the pachinko gaming machine according to the embodiment of the present invention will be described with reference to FIG. In FIG. 5, the same components as those of the EL light emitting panel 20 shown in FIG. In the illustrated example, the EL light emitting element 21 does not include the back surface protection layer 21 a, but has first and second binder layers 22 a and 22 b instead of the binder layer 22.

  The second binder layer 22b is the same layer as the binder layer 22 described in FIG. 2, and is interposed between the transparent electrode 21e and the decorative layer 23 of the EL light emitting element 21, and the transparent electrode 21e and the decorative layer 23 Are joined. However, the decorative layer 23 is not laminated on the panel base material 24, and the outer surface thereof is protected by the overcoat layer 29.

  The first binder layer 22a is interposed between the back electrode 21b of the EL light emitting element 21 and the panel substrate 24, and has an adhesive property that exerts an adhesive force on both the back electrode 21b and the panel substrate 24. ing. The first binder layer 22a does not need to have a light transmitting property for transmitting light emitted from the light emitting layer 21d of the EL light emitting element 21. Note that the first binder layer 22a also has an insulating property and a water barrier property as necessary because the EL light emitting element 21 does not have the back protective layer 21a. Further, a through hole 22c for exposing the back electrode 21b and a through hole 22d for exposing the transparent electrode 21e are formed on the outer surface of the first binder layer 22a.

  Two through holes 24a and 24b for opening the back electrode 21b and the transparent electrode 21e are formed on the outer surface of the panel substrate 24.

  When the EL light emitting panel 20 shown in FIG. 5 is produced, the second binder layer 22b is laminated on the inner surface of the decorative layer 23 in which the overcoat layer 29 is laminated on the outer surface, for example, by printing. The produced EL light emitting element 21 is laminated by bonding the transparent electrode 21e to the second binder layer 22b. Subsequently, the first binder layer 22a is laminated on the panel substrate 24 by printing or the like, and the EL light emitting element 21 is laminated by bonding the back electrode 21b to the first binder layer 22a.

  As a result, the panel base material 24 is disposed in the innermost interior when attached to the surface of the item to be decorated.

  Generally, when shipping as a product, the adhesive adhesive layer 25 is laminated on the outer surface of the panel base material 24, and a release sheet (not shown) is further laminated as necessary. Then, through holes 25 a and 25 b are formed in the adhesive bonding layer 25.

  As shown in FIG. 6, when the EL light emitting panel 20 is attached to the decorative article 30, the release sheet is peeled off from the EL light emitting panel 20 to expose the adhesive layer 25. And the EL light emission panel 20 is affixed on the attachment surface of the to-be-decorated goods 30 with the adhesive bonding layer 25 (attachment). At this time, the electrode 33 and the through holes 25a and 25b are connected.

  In addition, also about the EL light emission panel 20 demonstrated in FIG. 5, the attachment surface of the to-be-decorated goods 30 may be shape | molded in a groove shape, and you may make it fit the attachment surface in the EL light emission panel 20. Further, in both the EL light emitting panels 20 described with reference to FIGS. 2 and 5, the panel base member 24 may be slightly curved or have an uneven structure.

  By the way, when the above-described EL light emitting panel 20 is used for a front panel of a pachinko gaming machine, a nail is inevitably struck into the EL light emitting panel 20 because a nail is attached to the front panel. Become. For example, a nail hole is formed at a predetermined position of the EL light emitting panel 20, and the nail is disposed (struck) in the nail hole.

  However, since the EL light-emitting panel 20 includes the back electrode 21b and the transparent electrode 21e, when the nail is inserted into the nail hole, the back electrode 21b and the transparent electrode 21e may be short-circuited by the nail. . Even if the surface of the nail is insulated, the transparent electrode 21e comes into contact with the back electrode 21b through the nail and the short circuit occurs when the insulation property deteriorates.

  In order to reliably prevent such a short circuit, here, when forming the nail hole, the nail hole is formed using a laser beam. Referring to FIG. 7, FIG. 7 is a view showing a cross section of the EL light emitting panel 20 described with reference to FIG. 2 (the same applies to the EL light emitting panel 20 described with reference to FIG. 5). As shown in the drawing, the EL light emitting panel 20 is irradiated with laser light from the outer surface (surface) thereof. The diameter of the laser beam is approximately equal to the diameter of the nail hole.

  The position where the nail hole 41 is formed on the EL light emitting panel 20 is defined in advance, and the nail hole 41 is formed on the EL light emitting panel 20 by irradiation with laser light. When the nail hole 41 is formed by laser light, holes are opened in the back electrode 21b and the transparent electrode 21e, but holes are also formed in other layers other than the back electrode 21b and the transparent electrode 21e.

  At this time, the substance (material: insulator, etc.) melted by the laser beam adheres to the inner wall surface of the nail hole 41. That is, the inner wall surface of the nail hole 41 is coated with an insulator or the like (the coating layer 43 is formed). In this example, the panel base material 24 becomes the surface, and the nail hole 41 is formed from the panel base material 24 side (On the other hand, when the EL light emitting panel 20 shown in FIG. 5 is used, The nail hole 41 is formed from the overcoat layer 29 side with the overcoat layer 29 as a surface).

  In this way, when the nail hole 41 is formed in the EL light emitting panel 20 by the laser beam, the inner wall surface of the nail hole 41 is coated with an insulating material. As shown in FIG. When the nail 42 is struck, even if the insulation of the nail 42 deteriorates, a short circuit does not occur between the back electrode 21b and the transparent electrode 21e. Furthermore, even if the nail 42 is not insulated, it is possible to reliably prevent a short circuit between the back electrode 21b and the transparent electrode 21e (in FIGS. 7 and 8, the adhesive adhesive layer 25 and the decoration) The product 30 is omitted). The tip of the nail 42 is held by a substrate (not shown).

  In the above example, an example in which a nail hole of a pachinko gaming machine is formed with a laser beam has been described. However, the present invention is not limited to a pachinko gaming machine, and an EL light emitting panel is used as a display panel. The game machine can be applied in the same manner as long as the game machine is provided with a nail for guiding the game.
