Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention belongs to the technical field of a ball game machine represented by a pachinko machine, and more particularly to a cosmetic material attached to a game board of the ball game machine.

[0002]

2. Description of the Related Art In a ball game machine typified by a pachinko machine, a prize winning device, obstacle nails, windmills, etc. are installed on a game board, and the game ball contacts the prize winning device etc. to change its course and win the prize. A game is played depending on whether or not to play, or which winning device to win the prize.

Usually, a game board is made of plywood, and a decorative material having various designs and the like is attached to the surface thereof. The cosmetic material is not easily scratched even when it comes into contact with the game balls, and is hard to be damaged when hitting obstacle nails or cutouts corresponding to winning holes. Since it is required to have easy printability, a celluloid sheet or a sheet obtained by impregnating paper with a melamine resin has been used.

In printing a design or the like, the base is white or white to increase the contrast between the design and the base (for easy visual recognition). However, although the white (white-based) base has a higher reflectance than the colored portion, it does not totally reflect light, so that the contrast may be insufficient depending on the color and form of the printed portion.

As a technique for solving such a problem, as described in Japanese Patent No. 26603939, a transparent material and a metal plate are laminated without forming a base, and a pattern is formed on either of them. There is a decorative material that has been printed. According to the decorative material described in Japanese Patent No. 26605539, the contrast can be increased by the high reflectance of the metal plate, and the design or the like can be displayed clearly.

[0006]

However, the patent No. 26
The decorative material described in Japanese Patent No. 60539 has room for improvement. Firstly, since a structure in which a metal plate (metal foil) is laminated with a transparent material is required, the work of adhering the two is necessary, and the work process is complicated.

Since the metal foil has a small tensile strength,
The bonding work was difficult. On the other hand, if a metal plate thicker than the foil is used, even if it has tensile strength, it will be difficult to flatten it if it is used in a roll. To increase.

Next, in order to eliminate the directivity of the reflected light by the metal plate, the surface of the metal plate is made matte, but in terms of irregular reflection, it is the same as the conventional white base, and the contrast is improved. There was no decorative effect. The present invention is
In the decorative material of the game board, the printed part and its surroundings (base)
It is intended to secure a sufficient contrast with, to further simplify the manufacturing process, reduce cost, and improve decorativeness.

A decorative material for a game board according to claim 7 is the decorative material for a game board according to any one of claims 1 to 6,
The printing layer is provided by ultraviolet printing in which an ultraviolet curable ink is applied and is irradiated with ultraviolet rays to be solidified.

[0015]

BEST MODE FOR CARRYING OUT THE INVENTION The decorative material according to any one of claims 1 to 7 is a light-transmitting resin film as a surface layer film, a printing layer provided on the back side of the surface layer film, and a printing layer provided on the back side of the printing layer. It is provided with a reflective layer and a mount placed on the back side of the reflective layer and attached to the game board.

The printing layer provided between the surface layer film and the reflective layer is printed on one of the film or paper holding the surface layer film or the reflective layer. The printing method is not limited, and known printing methods such as silk printing and offset printing can be adopted. However, if it takes time to solidify the ink (so-called dry), the time efficiency of the printing process is not good.

Therefore, in the decorative material for the game board according to the seventh aspect, the ultraviolet curable ink (UV ink) is used as the ink. With UV ink, it can be said that there is almost no waiting time for drying because it solidifies only by irradiating it with ultraviolet rays for a very short time (for example, several seconds) after application. This can prevent the time efficiency of the printing process from being deteriorated.

The reflection layer is formed by vapor-depositing a metal on the reflection pattern surface, which is composed of a large number of small sections, as a base. What is characteristic of the inventions of the claims of the present application is that the directions of reflected light from the small sections are not uniform. Further, the reflective layer is divided into a plurality of regions, and the point that the reflection pattern in units of regions is common to some or all of the plurality of regions is also characteristic of the invention of each claim of the present application. .

First, the small section will be described. Subdivision
Means that the area is not large, for example
If 0.5mm ² ~ 10 mm² Dimension is illustrated
However, it may be slightly smaller or slightly larger than this.
Yes. In addition, about 0.8 mm is preferable.² (Diameter 1 mm
Equivalent to a circle) ~ 6 mm² It is a degree. Shape of each subdivision
Can be circular, rectangular, irregular, etc.
I don't know.

The metal vapor-deposited on the reflection pattern surface composed of a large number of small sections functions as a reflection layer, but the directions of reflected light from the respective small sections are not uniform. When the directions of the reflected light are not uniform, it means that the directions of the reflected light from each small section are not uniform when the parallel light is irradiated, and the angles of the reflected light from all the small sections are the same. , The angle of reflected light of a small section in a certain area is the same, or the angle of reflected light of a series of small sections along a certain straight line is not the same. For example, if the angles of the reflected lights of the adjacent small sections are different from each other, and two certain small sections are located at distant places, the angles of the reflected lights may be the same. In short, the direction of reflected light is random as a whole.

Since a lot of lights are arranged in the game store where the ball game machine is installed, and the ball game machine itself is also provided with an electric decoration, incident light from random directions is incident on the cosmetic material. is there. Since the directions of the reflected light from the large number of small sections are random as a whole, small sections that are brightly reflected and dark small sections can be formed depending on the viewing direction. The reflection by such small sections is different from the case where the metal surface is matte (diffuse reflection), and it shines like the reflection of fish scales or the reflection of sunlight on the water surface with waves. It becomes reflection, and the reflection pattern changes depending on the viewing direction.

There is no limitation on the method of making the directions of the reflected light from each small section uneven, but as described in claim 4, a method of providing a diffraction grating in each small section and making the directions of the grating lines uneven There is. In addition, making the direction of the grid lines uneven is
It means that the subdivisions are not aligned, and does not mean that the subdivisions are not aligned.

The angle (i) of the incident light by the diffraction grating (more precisely, a reflection type diffraction grating) and the angle (θ) of the reflected light (more precisely, the diffracted light), the incident light and the reflected light are normal to the diffractive surface. When the opposite side across the

[0024]

## EQU00001 ## d (sini-sin .theta.) = N.lamda. D: spacing of lattice lines, n: integer, .lamda .: wavelength of incident light (monochromatic light).

In the above equation, n is the order of diffraction, and the energy decreases (darkens) as the order increases. Also, when the spectrum is divided into many orders, the energy of each becomes small and it becomes dark.
It can be concentrated in the second or second order spectrum (blaze grating, echelette grating).

Since the spectral action due to the diffraction grating becomes remarkable in the direction along the plane perpendicular to the grating line, if the directions of the grating line are made uneven among the small sections, the incident light from a certain direction is not obtained. , Only certain parcels appear to be reflecting. And, since a lot of lights are arranged in the game store where the ball game machine is installed and the ball game machine itself is also provided with the electric decoration, the decorative material has incident light from random directions. If the direction in which the player sees the cosmetic material changes, the small section that emits the reflected light in the direction toward the player also changes. Therefore, there are small blocks that are brightly reflected and dark blocks depending on the viewing direction, and like the reflection on the water surface with fish scales and waves as described above, it will be a glittering reflection, and the pattern of reflection will depend on the viewing direction. Changes.

As a method of making the directions of the reflected light from the respective small sections uneven, the structure described in claim 5 may be adopted.
The angle of inclination of the small plane (small section) corresponds to the angle between the small plane and the surface of the surface layer film. Not matching the tilt angles means that all facets have the same tilt angle, facets in a certain area have the same tilt angle, and a series of facet tilts along a straight line. The angles do not become the same, for example, the state where the inclination angles of adjacent small planes are different from each other. Thus, if two facets are in separate locations, their tilt angles may be the same. In short, it means that the tilt angle is random as a whole.

Also in this case, the direction of the reflected light of the light incident on the reflecting layer from the surface of the decorative material (surface layer film side) becomes random for each small plane. Then, as described above, the reflection becomes shining like the reflection on the water surface with fish scales and waves, and the reflection pattern changes depending on the viewing direction.

Next, the second characteristic point, that is, the reflection layer is divided into a plurality of areas, and the reflection pattern in units of the areas is a part of the plurality of areas (that is, the area of the reflection layer). Explain the points that are common in some or all areas. The reflection pattern in units of regions is a reflection pattern composed of many small sections included in the region.

Since the external dimensions of the reflective layer are almost the same as those of the decorative material, the number of small sections contained therein is extremely large. The approximate size of the game board is 450 mm x 450 m
Assuming that the size of one small section is 1 mm × 1 mm, the number of small sections is 202,500. Even if the area of one small section is doubled, it will be about 100,000.

In order to form such a reflection pattern surface composed of a large number of small sections at once, a large stamp or die having such a fine structure is required. The production of such a large and precise stamp is not easy, the so-called die cost becomes high, and the production cost of the decorative material also becomes high.

In order to avoid such a problem, the inventions of the respective claims of the present application make a reflection pattern in units of regions common to some or all of the plurality of regions.
By adopting this configuration, it is possible to reduce the size of a mold or the like (for example, a stamp) for forming the reflection pattern surface. As a result, the unit price of the stamp or the like can be reduced.

If the area-based reflection pattern is common to all the areas, for example, only one stamp will be required. Therefore, the so-called mold cost does not increase, and the manufacturing cost of the decorative material does not increase. Also,
Even if there are several kinds of stamps (for example, about 2 kinds to about 10 kinds), the cost can be suppressed similarly.

For example, the smaller the stamp, the lower the cost of the stamp, but there is a limit to that. Also,
If the area size (size of stamp or the like) is too small, the processing for forming the reflection pattern surface becomes difficult. Therefore, the size of the area, that is, the number of divisions of the reflecting surface is naturally limited, and is at least about 10 mm × 10 mm, preferably 20 mm × 20 mm or more.

On the other hand, if the size is too large, it becomes difficult to reduce the die cost, as in the case where the region is not divided. Therefore, the size of the area is 20 mm x 20 mm to 60 mm x 6
About 0 mm is preferable. However, it is not necessary to stick to this dimensional value. If the pattern of reflection in units of areas is common to some or all of the areas, it becomes a repeating pattern in units of one or more areas, but the reflection by the subdivisions contained in each area as a whole. Since it becomes random, the effect of making the directions of the reflected light from each small section uneven is not impaired.

To provide the reflection pattern surface of the reflection layer, a metal stamp or a metal roller provided with irregularities corresponding to the reflection pattern in units of areas may be used. As described above, the cost of the decorative material can be suppressed by downsizing the metal stamp and the metal roller.

When the reflection pattern surface is provided on the reflection film according to claim 2, the reflection film surface may be directly provided on the reflection film, or a pattern formation layer may be provided on the surface of the reflection film. May be processed into a reflection pattern surface. On the other hand, when the reflective layer is formed on the surface of the reflective paper as described in claim 3, a resin layer (for example, a lacquer layer) is provided on the surface of the reflective paper, and a reflective pattern surface is provided on the resin layer. .

The metal may be deposited on the reflection pattern surface of the reflection film or the reflection paper by a known method.
The metal to be vapor-deposited is not limited, and aluminum, copper, silver and the like can be exemplified, but aluminum is superior in view of cost. Since the printing layer is provided between the reflecting layer and the surface layer film, a part of the light incident from the surface of the decorative material is reflected or absorbed by the printing layer and the rest is reflected by the small section. Since the reflection in the small section is the reflection due to the metal vapor deposition layer, the reflectance is sufficiently high. And, as mentioned above, the reflection is rich in variation.

Therefore, sufficient contrast between the printed layer and the underlying layer is secured, and the decorative property is also improved. Since the reflection pattern surface can be provided by using a metal stamp or a metal roller having a size corresponding to the divided area of the reflection layer, its formation is easy. Further, the formation of the reflection layer (vapor deposition of metal) is easy. Therefore, the manufacturing process can be simplified and the cost can be reduced. In addition, since it is not necessary to bond the metal foil or the like to be the reflective layer, there is no problem in the structure for bonding the metal foil or the like.

When the surface layer film and the reflection film are copolymerized polyester resin films as described in claim 6, when an acrylic emulsion adhesive is used for adhesion of both films, the adhesive is excellent and uniform over the entire surface. It is dispersed and does not impair the aesthetics of the cosmetic material, and also has sufficient adhesive strength.

Since the surface film is required to have resistance to nailing and punching, it is preferable to use an unstretched film of a copolyester resin. A typical example of the unstretched film of the copolyester resin is Spectar (trade name) copolyester sheet 14471 manufactured by Eastman Chemical Company. In addition, Spectar
(Product name) Copolyester sheet 14471 (hereinafter P
It is called ETG. The physical properties of () are as shown in Table 1 below.

[0042]

[Table 1]

As is clear from Table 1,
This PETG is excellent in mechanical strength, and also excellent in elasticity and flexibility. In addition, since it is a non-stretched sheet, there is no orientation or stress remaining due to stretching, and when a hole is created in a prize winning device or an obstacle nail is hammered in, mechanical breaks or scratches develop from those mechanical scratches. There is no such thing.
Moreover, it is sufficiently flexible, is well compatible with the plywood game board, and there is no fear that the rebound of the game ball will become too strong.

For this PETG, for example, offset printing, gravure printing, silk screen printing,
Various known printings such as UV printing can be performed. Moreover, any ink suitable for acrylic or polycarbonate can be used without problems, and it is not necessary to use a special ink.

In order to bond the polyester resin film, which serves as the reflection film, and the backing sheet together, as described in claim 6,
A modified polyester adhesive may be used. Generally, when the resin film and the paper are adhered, the application (dispersion) of the adhesive may be non-uniform. If the application (dispersion) of the adhesive becomes non-uniform, the aesthetic appearance will be impaired, so it was fatal as a decorative material for game boards.

Further, when a paper having a small surface roughness such as glossy paper is used in order to make the dispersion of the adhesive on the adhesive surface with the paper uniform, there is a problem that the adhesion between the paper and the plywood of the game board is not successful. there were. However, when the reflective film (polyester resin film) and the backing paper are adhered with a modified polyester adhesive, the dispersion of the adhesive between the layers is well and even, and the adhesive strength is sufficient, so that the aesthetic appearance is not impaired and practical With sufficient adhesive strength to withstand. Further, since it is not necessary to use a paper having a small surface roughness and a mount having a large surface roughness can be used, the problem that the bonding between the mount and the game board (plywood) does not work is solved.

When the reflective layer is provided on the surface of the reflective paper as claimed in claim 3, the reflective paper may also serve as the mount, but the paper quality suitable for the reflective paper and the paper quality suitable for the mount are not the same. Since it does not exist, it is preferable to have a structure in which the backing paper is attached to the backing paper.

[0048]

Embodiments of the present invention will now be described more concretely by describing embodiments of the present invention with reference to the drawings. As shown in FIG. 1, the decorative material 1 of this example has a surface layer film 10 of PETG, a reflection film 12 of a polyester resin film, a reflection pattern 12a provided on the back surface of the reflection film 12, and a reflection pattern 12a on the back surface. Reflective layer 12 obtained by vapor deposition of metal (aluminum in this example)
The surface layer film 10 is provided with a printing layer 10a on the back surface thereof. Then, the back side of the mount 14 is attached to the surface of the game board 16 made of plywood.

The decorative material 1 is made into a laminated material by adhering the roll-shaped mount 14 and the reflective film 12 in a roll-like shape on which the reflective layer 12b is already vapor-deposited with a modified polyester adhesive to form a laminated material. The printing layer 10a is already printed on the material
It is manufactured by adhering the surface layer film 10 on which is provided with an acrylic emulsion adhesive.

In this example, LX-75A [Elastomer (trade name EPS75A) and curing agent (trade name KW4) manufactured by Dainippon Ink and Chemicals, Inc. was used as the modified polyester adhesive.
0) and a two-component adhesive that is mixed at a ratio of about 5: 1]
Was used. Acrylic emulsion adhesive is trade name S
A-T630W (Tokyo Ink Co., Ltd.) was used. The acrylic emulsion adhesive is a product name SA-T
610W (Tokyo Ink Co., Ltd.) can also be used.

The printing layer 10a is formed by applying an ultraviolet curable ink (UV ink) to the back surface of the surface layer film 10 by silk screen printing and irradiating it with ultraviolet rays to solidify it. As shown in FIG. 2, the decorative material 1 of this example is divided into a grid pattern, and each square portion is divided into divided areas 5 respectively.
It is said that. In the case of this example, the divided region 5 is a square, and its size is approximately 20 mm × 20 mm.

As shown in FIG. 3, the reflection pattern 12a provided on the reflection film 12 of the present example has a circular (diameter of about 1 mm) small section 20a and a random polygon (triangle to hexagon). It is a combination with the section 20b. The reflection pattern composed of such a combination of the small sections 20a and 20b uses the divided area 5 as a unit, and is common to all the divided areas 5 in this example. That is, the entire surface of the decorative material 1 is formed by repeating the reflection pattern 12a in units of the divided areas 5.

As shown in FIG. 4, each small section 20a, 20
A diffraction grating is provided at b, and the directions of the diffraction lines 21 are not uniform. Therefore, which small section 20a, 20b is brightly reflected and which small section 20a, 20b is dark differs depending on which direction the player sees. Then, if the viewpoint changes, the light-dark pattern of the small sections 20a, 20b changes. Moreover, this change in the reflection direction does not occur pointwise (not diffuse reflection like a matte surface), and the small sections 20a and 20b are used as a unit. In other words, the reflection by the small sections 20a, 20b becomes a glittering reflection, as when sunlight is reflected on the water surface with fish scales and ripples, and the reflection form changes depending on the viewing direction.

Furthermore, since the reflection is due to the diffraction grating,
Light such as illumination in a game store (which can be regarded as white light) is dispersed (rainbow-like color change occurs), so that various color shades are obtained depending on the viewing angle and position, which also enhances the decorative effect. Since the reflectance of the light reflected by the small sections 20a and 20b is sufficiently high, a sufficient contrast with the printing layer 10a is secured and the decorativeness is also improved.

In the case of this example, the reflection pattern 12a is formed of a metal stamp having a size corresponding to the divided area 5. Since the reflection pattern 12a of the decorative material 1 can be formed by repeating stamping with one metal stamp, the die cost does not increase. Of course, it is also possible to improve the manufacturing efficiency by stamping by using a plurality of metal stamps of the same shape at the same time. Further, vapor deposition of metal for forming the reflective layer 12b is also easy. Therefore, the manufacturing process can be simplified and the cost can be reduced. In addition, since it is not necessary to bond the metal foil or the like to be the reflective layer, there is no problem in the structure for bonding the metal foil or the like.

Note that FIG. 3 does not show the reflection pattern accurately, but is simplified for convenience of explanation. Further, FIG. 4 shows only the direction of the diffraction lines 21, and the actual density of the diffraction lines 21 is about 600 to 1200 per 1 mm. Further, instead of the reflective film 12, FIG.
The reflection paper 32 having a schematic structure may be used. A resin layer 32a made of a metal lacquer is formed on the surface (the surface film 10 side) of the reflection paper 32, and the same reflection pattern surface as described above (a reflection pattern in which the directions of the lattice lines of a large number of small sections are not uniform is formed on the surface thereof. ) Is provided and aluminum is vapor-deposited on the reflection pattern surface to form the reflection layer 32b. Even with this configuration, the same effect as that of the embodiment can be obtained.

[0057]

[Modification] Instead of providing diffraction gratings in each of the small sections 20a and 20b to make the directions of the grid lines uneven, each of the small sections 2
0a and 20b may be small planes, and the inclination angles of the small sections 20a and 20b may be uneven as shown in FIG.
Note that FIG. 5 does not accurately show the dimensions and the like of the small sections 20a and 20b, and is simplified for convenience of explanation.

In the example shown in FIG. 5, the reflection direction differs depending on which small section 20a, 20b the incident light is reflected on. Even parallel rays are reflected in various directions. Then, this change in the reflection direction does not occur pointwise (not diffuse reflection such as a matte surface), and the small sections 20a and 20b are used as a unit.

That is, the reflection by the small sections 20a, 20b becomes a glittering reflection, as when sunlight is reflected on the water surface with fish scales and ripples, and the reflection pattern changes depending on the viewing direction. Since the reflectance of the light reflected by the small sections 20a and 20b is sufficiently high, the printing layer 10a
And a sufficient contrast is secured, and decorativeness is also improved.

The reflection pattern 12a can be easily formed by, for example, a stamp, and vapor deposition of a metal for forming the reflection layer 12b is also easy. Therefore, the manufacturing process can be simplified and the cost can be reduced. In addition, since it is not necessary to bond the metal foil or the like to be the reflective layer, there is no problem in the structure for bonding the metal foil or the like.

The embodiments of the present invention have been described above according to the embodiments, but the present invention is not limited to such embodiments, and various modifications can be made without departing from the gist of the present invention. Needless to say.

[0062]

As described above, in the decorative material for the game board according to the first aspect of the present invention, the reflective layer formed by vapor-depositing metal on the reflective pattern surface composed of a large number of small sections is used as the base of the printing layer. A sufficient contrast between the layer and the underlying layer can be secured, and the reflection by the reflection pattern surface is rich in variation, so that the decorative property is also improved.

Further, since the reflection layer is divided into a plurality of regions and the reflection pattern in units of the regions is made common to some or all of the plurality of regions, the reflection pattern surface is formed. A mold or the like (for example, a stamp) can be downsized. As a result, the unit price of the stamp or the like can be reduced.

The reflection pattern surface can be easily formed by, for example, a metal stamp, and metal vapor deposition is also easy, so that the manufacturing process can be simplified and the cost can be reduced. Moreover, since it is not necessary to bond the metal foil or the like as the reflective layer, there is no problem in the structure for bonding the metal foil or the like.

In the decorative material for the game board according to the second aspect, since the reflective layer is provided on the translucent resin film, a resin film of the same type as or similar to the surface layer film can be used as the reflective film. It is possible to avoid problems such as wrinkles when there is a difference in the degree of expansion and contraction between the surface layer film and the reflection film due to changes in humidity and humidity.

In the decorative material for the game board according to the third aspect, since the reflective layer is provided on the reflective paper, this can also be used as the mount.
If the backing paper and the reflection paper are separately provided, it is possible to use paper having a suitable paper quality. Since the decorative material for the game board according to claim 4 is provided with the diffraction grating in each small section and the directions of the grating lines are uneven, the effect according to claim 1 can be exerted.
You can also enjoy the color change due to the spectral effect.

In the decorative material for the game board according to the fifth aspect, since the inclination angles of the respective small sections are uneven, the effect according to the first aspect can be exhibited, and the microscopic structure of the reflection pattern can be simplified. In the decorative material for the game board according to claim 6, the reflective film and the surface layer film are both made of a copolyester resin film, and the acrylic emulsion adhesive is used for bonding the reflective film and the surface layer film.
The adhesive is well and uniformly dispersed over the entire surface without impairing the aesthetic appearance as a cosmetic material, and the adhesive strength between both films is sufficient.

Further, since the reflective film and the mount are adhered with the modified polyester adhesive, the dispersion of the adhesive between the reflective film and the mount is well uniformed and the adhesive strength is sufficient. It is not damaged and has sufficient adhesive strength for practical use. Further, since it is not necessary to use a mount having a small surface roughness and a mount having a large surface roughness can be used, the problem that the mount and the game board (plywood) are not bonded well is solved.

In particular, if an unstretched film of a copolyester resin is used, no cracks or the like will occur even if the nails are driven in or cut out for attaching a prize winning device or the like. Therefore, nailing or punching can be performed after the decorative material is attached to the game board.

Since the cosmetic material for the game board according to claim 7 uses the ultraviolet curable ink as the ink, the ink solidifies only by irradiating the ultraviolet light for a very short time (for example, several seconds). Since there is almost no time, it is possible to prevent deterioration of time efficiency in the printing process.
