Description

Technical Field

[0001] The present invention relates to a gaming machine and a method for manufacturing the same.

Background Art

[0002] The decorative properties of gaming machines such as ball shooting gaming machines and slot machine gaming machines have been increasingly required to be sophisticated year by year, and various proposals have been made. For example, Patent Document 1 discloses a protective film for a gaming board, which includes a first adhesive layer made of an adhesive that adheres to the gaming board, a first resin film laminated on the upper surface of the first adhesive layer, a printing layer and a second adhesive layer provided on the upper surface of the first resin film, a second resin film laminated on the upper surface of the printing layer and the second adhesive layer, and a hard coat layer laminated on the upper surface of the second resin film.

[0003] Patent Document 2 discloses a gaming board in which a pattern forming member formed by laminating, on a film member having translucency formed in a sheet shape, at least an offset printing pattern layer in which a predetermined pattern is formed by offset printing and a hard coat layer for protecting the offset printing pattern layer, and a plate-shaped base material are attached via an adhesive having heat resistance.

[0004] In view of the fact that problems in integrating a transparent surface material and a backing material having uneven thickness due to a design pattern such as a printed coating film by heat and pressure are mainly caused by the characteristics of the adhesive member, Patent Document 3 discloses a decorative board for a gaming board in which the adhesive member is a film-shaped adhesive member made of a partial saponified product of ethylene vinyl acetate copolymer, so that an adhesive member having excellent transparency and adhesiveness and an arbitrary and uniform thickness can be formed, and it is possible to fill the uneven thickness of the printed coating film.

[0005] Patent Document 4 discloses a decorative structure of a gaming machine, which includes a colored reflective portion in which a metallic reflective layer such as a metal foil or a hologram and a colored layer made of a colored ink are stacked in the thickness direction, and the thickened portion is disposed at a position including at least a part of the rear surface of the colored reflective portion.

[0006] Furthermore, Patent Document 5 disclosed a gaming machine sheet comprising a decorative resin sheet, the decorative resin sheet comprising a sheet body, a colored layer disposed on its rear side, and a decorative layer disposed on its rear side, the decorative layer comprising a raised portion and a metallic reflective layer disposed on its rear side, the raised portion being positioned to include at least a portion of the rear surface of the colored layer and protruding rearward from the rear side of the colored layer, the metallic reflective layer being disposed on at least a portion of the rear surface of the raised portion and the metallic reflective layer being disposed on the rear surface of the raised portion, the metallic reflective layer constituting a metallic concave curved reflective surface, and a structure in which the reflected light from the metallic concave curved reflective surface can be seen when the player looks at the sheet from the front.

[0007] However, the inventions described in Patent Documents 4 and 5 aimed to improve the decorative aspect by allowing players to see the light from the game room and other areas as reflected light from a metallic concave reflective surface when viewing the seat from the front, as described above. Therefore, no particular disclosure was made regarding the relationship with the light-emitting part on the rear side.

[0008] Furthermore, Patent Document 6 disclosed the use of a curved mirror sheet having a metallic reflective layer such as metal foil or a hologram and a Fresnel lens structure as a decorative structure for amusement equipment. The invention in this document also required a metallic reflective layer and aimed to enhance decorative properties by reflecting light from the front-facing indoor lighting using the curved mirror sheet. For this reason, the irregularities of the Fresnel lens structure were oriented towards the front, and the curved mirror sheet was removed or otherwise eliminated in areas where light from the rear-facing light-emitting part was to be visible from the front.

[0009] On the other hand, amusement machines are devices that undergo frequent model changes and changes to their design to attract the attention and interest of players. In such cases, it is necessary to manufacture molds from scratch or partially modify the molded parts mentioned above. In particular, recently, the various designs applied as decorations to amusement machines are equipped with various shapes of light refractors to bend the light from the light source accordingly. The shape of the molded part is determined including these light refractors, and a mold is created accordingly for molding. Therefore, even if the external shape of the molded part is almost identical, a separate mold is required if the light refractor is different. However, since manufacturing and modifying these molds is very expensive, ideally, one mold would be used for multiple types of gaming machine models, with only the patterns needing to be changed. However, no concrete means to achieve this have been provided. As a result, even though it was common technical knowledge that standardizing molded parts and their molds was desirable for rationalizing manufacturing and reducing costs, the standardization of molded parts and their molds had not progressed at all.

[0011] The present invention aims to provide a decorative structure for amusement machines that can provide new decorative effects to players and other viewers while promoting the standardization of molded components and their molds. Furthermore, the present invention aims to provide a decorative structure for amusement machines that can provide fine irregularities with a light refraction effect to a molded member by printing technology, without the need to create them by mold processing. [Means for solving the problem]

[0012] The present invention provides a decorative structure for a gaming machine comprising a decorative member constituting the gaming machine, a light-emitting unit disposed on the rear side of the decorative member, and a decorative sheet disposed on the front side, rear side, or inside of the decorative member. The decorative member is translucent in at least a portion of it. The decorative sheet comprises a sheet substrate, a colored layer made of translucent colored ink laminated on the sheet substrate, and a translucent light-refracting portion laminated on at least the colored layer by printing, wherein fine irregularities are formed on the sheet substrate by the light-refracting portion. The decorative sheet is attached to the member to be decorated, and is configured such that light from the light-emitting portion is refracted by the fine irregularities caused by the light-refracting portion and is visible from the front side of the member to be decorated.

[0013] The decorative sheet can be implemented by attaching it to the front surface of the decorative member with a translucent adhesive layer, with the irregularities of the light-refracting portion facing the light-emitting portion. Furthermore, the decorative sheet can be implemented in a manner in which it is sandwiched and supported by the two decorative members, front and rear, without the use of adhesives or glues.

[0014] Furthermore, the decorated member is a molded part that is configured separately from the game board of the gaming machine and attached thereto, and the decorative sheet may be arranged on the surface of the molded part that does not have the concavo-convexities.

Advantages of the Invention

[0015] The present invention has been able to provide a decoration structure for a gaming machine that can give a new decorative effect to viewers such as players while promoting the common use of molding members and their molds. Also, the present invention has been able to provide a decoration structure for a gaming machine that can impart fine concavo-convexities having a light refraction effect by means of printing technology without providing them to a molding member by mold processing.

Modes for Carrying Out the Invention

[0017] The embodiments of the present invention will be described below with reference to the drawings. Note that the figures, such as Figure 1, are for illustrative purposes only and do not accurately represent dimensions such as the thickness of each layer. (Overview of Gaming Machine 11)

[0018] As shown in Figure 1, the gaming machine 11 according to this embodiment is implemented as a pachinko machine, and is equipped with a game board 16 having a running surface 17 at the top, and an upper ball receiver 13, a lower ball receiver 14, and a launching lever 15 at the bottom.

[0019] The game board 16 is provided with multiple prize slots 18 into which game balls (not shown) can be entered, and numerous obstacle pins 21 that guide the game balls and change their direction of travel. A window 19 is formed approximately in the center of the game board 16, and a variable display unit (not shown), such as a liquid crystal screen, is positioned in the window 19. This variable display unit changes its display in response to game balls entering the prize slots 18, and may be an optical display such as a liquid crystal display, or it may change its display due to mechanical movement such as the rotation of a rotating drum.

[0020] This game board 16, excluding the window portion 19 and the like, comprises a circuit board 31 as shown in Figure 2 and a front sheet 20 with various patterns as shown in Figure 3, which is placed on its front surface (the side visible to the player in front).

[0021] The substrate 31 provides strength to the game board 16 and may be made of a polyester resin such as polyethylene terephthalate (PET) resin, an acrylic resin such as polymethyl methacrylate, or a resin material such as polycarbonate, or it may be made of wood such as plywood made of lauan wood. These substrates 31 have a thickness of, for example, about 10 to 20 mm, which is sufficient to provide strength for use, and may be processed substrates in which window portions 19 are cut out of a rectangular flat plate, or openings for prize-winning devices called tulips or pockets are formed, or they may be molded substrates in which pilot holes for fixing these openings and fixing holes 32 for fixing obstacle nails 21 are formed in advance. (Regarding the decorative member 12)

[0022] The decorative structure for a gaming machine of the present invention can be implemented in various forms. Various molded parts such as the upper ball holder 13, the lower ball holder 14, and the launch lever 15, as well as a substrate 31 (particularly a molded substrate manufactured using a mold), can be used as the decorative member 12. However, considering the unique characteristics of gaming machines as mechanical devices that undergo frequent model changes, it is advantageous to use various molded products such as molded parts and molded substrates as the decorative member 12, as this promotes the standardization of molding dies.

[0023] The decorative member 12 is designed to be translucent in at least a portion of it. A front sheet 20 is positioned behind the translucent portion so that players in front can see the light from the light-emitting part 10. (Regarding the light-emitting part 10)

[0024] A light-emitting unit 10 is positioned behind the decorative member 12. The type of light-emitting unit 10 is not particularly limited; it can be any light source commonly used in amusement machines, such as LED lamps or fluorescent lamps, which emit point-like or linear light. A surface-emitting element such as an EL light is also acceptable, and in some cases, a light-emitting element other than visible light, such as an ultraviolet lamp or black light, may also be used. (Regarding decorative sheet 50)

[0025] A decorative sheet 50 is fixed to the front side of the decorative member 12 via an adhesive layer 40. The decorative sheet 50 can be modified as appropriate, primarily from the perspective of decorative design, such as having substantially the same shape as the decorative member 12 when viewed from the front.

[0026] In its cross-section, as shown in Figure 4, the decorative sheet 50 is placed in front of the decorative member 12 and bonded by an adhesive layer 40. It comprises a translucent synthetic resin sheet base material 51, a translucent colored layer 52 made of colored ink placed on the rear side of the sheet base material 51, and a light-refracting portion 53 placed on the rear side of the colored layer 52. This light-refracting portion 53 protrudes backward from the rear side of the colored layer 52. Here, in the present invention, "translucent" means having the property of transmitting light, and transparent or translucent materials can be used.

[0027] Hereinafter, "to the rear" is used to mean "further back than," and for example, "placing member Y on the rear side of member X" should be understood to include both the case where member Y is directly placed on the rear surface of member X and the case where a third member Z is interposed between the rear surface of member X and the front surface of member Y. Similarly, "to the front" is used to mean "further forward than." In this embodiment, the front-rear direction is used in the same sense as the thickness direction of the decorative sheet 50. (Regarding decorative sheet 50 and separate sheet)

[0028] Although not shown in the diagram, the decorative sheet 50 is generally transported and stored with the front separator sheet placed on its front side and the rear separator sheet placed on the rear side of the adhesive layer 40. The rear separator sheet is removed when it is bonded to the front surface of the decorative member 12, and the front separator sheet is removed when it is ready for use, but this is not the only option. Alternatively, the rear separator sheet may be placed on the rear side of the decorative sheet 50 where the adhesive layer 40 is not present, and the adhesive layer 40 may be applied at the stage of bonding with the decorative member 12. Depending on the type of adhesive, the adhesive layer 40 may be applied to the rear side of the decorative sheet 50 before placing the separator sheet, and the adhesive layer 40 may be activated and cured at the stage of bonding with the decorative member 12. (Regarding the sheet substrate 51)

[0029] For the translucent synthetic resin sheet substrate 51, films or sheets made of synthetic resins such as cellulose acetate butyrate (CAB) resin, polyethylene terephthalate resin, polycarbonate resin, acrylic resin, olefin resin, ABS resin, and vinyl chloride resin (hereinafter referred to as "resin film") can be used. When the front surface of the sheet substrate 51 becomes the running surface 17 of the game ball, high smoothness, strength, and durability are required, so it is also preferable to use resin films made of cellulose acetate butyrate (CAB) resin or polyethylene terephthalate (PET) resin. It is even more preferable to use a resin film made of cellulose acetate butyrate (CAB) resin because it has thermal expansion and contraction properties, self-healing properties, and is scratch resistant. Its thickness is not particularly limited, but is generally 50 to 400 μm, preferably about 100 to 200 μm. The resin film may be a single layer or a laminate of two or more layers. (Regarding colored layer 52)

[0030] A colored layer 52 made of translucent colored ink is formed on the rear surface of the decorated member 12 by printing. The colored layer 52 is also arranged planarly along the planar sheet substrate 51. The translucent colored ink can be a printing ink that has color and is translucent, and may also contain colorless transparent ink. Offset printing, screen printing, or inkjet printing can be used for this printing, but other printing methods such as gravure printing can also be used.

[0031] The thickness of this colored layer 52 is appropriately about 1 μm for offset printing and about 10 μm for screen printing, with a range of 1 to 20 μm being preferred and a range of 4 to 20 μm being more preferred, but it can be changed as appropriate.

[0032] The colored layer 52 is a layer that gives color to the decorative sheet 50 and also provides visual representations such as letters, figures, and patterns. The monochrome or multicolored colored layer 52 is formed by applying various printing techniques, either once or multiple times.

[0033] The colored layer 52 uses translucent colored ink so that the transmitted light is visible to the player in front of it. However, it is also possible to use opaque ink in some parts. For example, opaque ink can be used in some parts to conceal devices that are not to be seen by the player. Furthermore, instead of or in combination with this colored ink colored layer 52, metallic reflective foil can be used. Foil generally does not possess translucency, but foil with an extremely thin thickness of 120-140 Å or so and a light transmittance of 35% is also available. By using this type of foil, it is possible to create decorations that combine metallic reflectivity and translucency. (Regarding the light refraction section 53)

[0034] The light-refracting portion 53 is implemented as a translucent protrusion formed on the rear side of the colored layer 52. The light-refracting portion 53 is made using a translucent resin such as transparent or translucent so that the transmitted light can be seen by the player in front of it, however, from a decorative design standpoint, a non-translucent resin may be used in some parts.

[0035] The light-refracting portion 53, which is translucent, is positioned to include at least a portion of the rear surface of the translucent colored layer 52 and protrudes rearward from the rear side of the colored layer 52. The light-refracting portion 53 is formed by printing with a thick-layer ink made of synthetic resin such as epoxy resin, acrylic resin, urethane resin, or mixtures or compounds thereof, and may be semi-transparent as long as it is translucent, and may be colored with pigments or the like, similar to the colored ink.

[0036] At least the periphery of the light-refracting portion 53, which protrudes to the rear, has a convex curved surface 54 that curves toward the rear in the cross-section in the thickness direction of the sheet substrate 51 due to the surface tension of the thick ink during printing. The light is refracted at the interface between this convex curved surface 54 and the adhesive layer 40, and as refracted light, it passes through the colored layer 52 and the sheet substrate 51 and reaches the eyes of the player in front. In this way, the refracted light can work in conjunction with the various patterns and characters drawn on the colored layer 52 to give the player a visual effect.

[0037] The surface shape of the light refraction portion 53 can be changed in various ways. For example, it can be implemented as patterns or figures as shown in Figures 5a to 5s, or as a representation of characters or designs.

[0038] The thickness (t) and width (w) of the light-refracting portion 53 are major factors that affect the decorative effect of the decorative sheet 50. Therefore, the thickness (t) is preferably 75 μm or more, and more preferably 80 μm or more. The thickness (t) of the light-refracting portion 53 is the height of the unevenness between the light-refracting portion 53 and its adjacent parts. The larger the thickness (t), the greater the unevenness and the more the three-dimensional decorative effect can be enhanced. On the other hand, as the thickness increases, maintaining accuracy and mass production becomes difficult, and the materials that can be used become limited. Therefore, 150 μm or less is appropriate, and 100 μm or less is more stable, but this does not prevent implementation with a thickness exceeding 150 μm. For the width (w), 0.3 mm to 3 mm is appropriate to enhance a sharp decorative effect. However, this is determined by the figures or characters to be drawn, and is not limited to this when obtaining a decorative effect over a large area. The width of the light-refracting portion 53 refers to the width of the surface in contact with the rear surface of the colored layer 52.

[0039] To obtain this thickness, it is advantageous to perform silkscreen printing with a large layer thickness. In this case, printing may be performed multiple times, from one to about five times. Multiple types of light-refracting sections 53 with different thicknesses may be formed by partially changing the number of printing passes. On the other hand, by making the thickness of the light-refracting sections 53 the same, the printing plates can be used in common when performing printing, thereby increasing production efficiency.

[0040] The decorative sheet 50 is suitable for application to a surface of the molded part 12 that does not have any irregularities for refracting light (for example, a smooth surface). This eliminates the need to form irregularities for refracting light on the molded part 12 by molding. As a result, each time the pattern created by the colored layer 52 changes, it is no longer necessary to create a new mold for the molded part 12 and remolde the molded part 12 to obtain the corresponding decorative effect from refracted light. If a mold for a standard molded part 12 without irregularities for refracting light is manufactured, even if the pattern created by the colored layer 52 changes, it is sufficient to simply form the corresponding irregularities with the light-refracting portion 53 during the printing stage of the colored layer 52.

[0041] Moreover, when forming the uneven surface on the molded part 12 by molding, it is necessary to change the mold each time the shape of the uneven surface is changed, which is time-consuming and costly even for minor changes. In contrast, in this embodiment, only the printing mold for the light-refracting portion 53 needs to be changed, so it can be done quickly. Therefore, for example, at the test printing stage, it is possible to check the optical decorative effect of the light-refracting portion 53 and the overall decorative effect of this and the printed pattern of the colored layer 52, and if necessary, the decorative effect intended by the designer or manufacturer can be reliably and quickly obtained by changing either the light-refracting portion 53 or the colored layer 52. Furthermore, since the colored layer 52 and the light-refracting portion 53 are formed on a common molded part 12, the accuracy of their alignment is improved.

[0042] The decorative sheet 50 according to this embodiment offers a high degree of freedom in material selection, such as having heat resistance that can withstand high temperatures of 135°C. For example, the curved mirror sheet used in the gaming machine described in Patent Document 6 required vacuum forming to create protrusions on the front surface of the sheet, which limited the heat resistance of the sheet in order to improve its moldability. However, the decorative sheet 50 according to this embodiment allows the unevenness of the light-refracting portion 53 to be formed by printing rather than molding, so it is possible to use a general sheet used in gaming machines, and a gaming machine with high quality stability can be provided. In addition, adjustment layers or other layers may be added to obtain thickness or smoothness, etc. (Regarding the adhesive layer 40)

[0043] The adhesive layer 40 is for bonding with the decorative member 12, and while acrylic adhesives or other adhesives can be used, it is not limited to these. Any adhesive that achieves good adhesion in relation to the materials of the decorative member 12 and the decorative sheet 50, as well as the colored layer 52 and the light-refracting portion 53, is acceptable. Depending on the type of adhesive layer 40, its thickness should be greater than the thickness of the light-refracting portion 53(t), and a thickness of about 0.2 to 0.3 mm is appropriate. (Placement of decorative sheet 50)

[0044] As described above, the decorative sheet 50 is placed on the front side of the decorated member 12, and the coloring of the colored layer 52, which passes immediately after the light from the light-emitting part 10 is refracted by the light-refracting part 53, gives a visual effect to the design expressed by the coloring. Furthermore, by allowing only the sheet substrate 51, which is sufficiently thin compared to the decorated member 12 and about 50 to 400 μm thick, to pass through and reach the eyes of the player in front, the visual decorative effect can be expressed and felt to the greatest extent. Note that Figure 4 is for showing the positional relationship of the layer structure, and the distance from the front sheet 20, the ratio of the thickness of the decorated member 12 to 50, and the ratio of the thickness of each layer of the decorative sheet 50 are not shown accurately.

[0045] However, the placement of the decorative sheet 50 may be changed for reasons other than visual effect. For example, Figure 6 shows an example where the decorative sheet 50 is placed on the rear side of the decorated member 12. Figure 7 shows an example where the decorative sheet 50 is placed inside, sandwiched between the front and rear decorated members 12. In this case, the decorative sheet 50 may be attached with an adhesive or glue, but it can be supported by the decorated member 12 without one. If not attached, it is easy to replace the decorative sheet 50 after completion, and it is also possible to change the design. In addition, in embodiments other than those shown in Figure 7, the decorative sheet 50 may be attached to the decorated member 12 using screws or fixing members without using an adhesive or glue. Figure 8 also shows an example in which the light-refracting portion 53 of the decorative sheet 50 is positioned to protrude toward the decorated member 12 and attached via the adhesive layer 40. (Application of decorative sheet 50 to the decorated member 12)

[0046] The decorative sheet 50 is applied to the gaming machine while maintaining a smooth, flat state, but it can also be applied to the gaming machine in a three-dimensionally curved or bent state according to the shape of the decorative member 12. It can also be applied to slot machines other than pinball gaming machines, and can be used, for example, on the rotating reels of a slot machine, the casing of the gaming machine around them, or as an emblem sheet.
