Abstract

PROBLEM TO BE SOLVED: To solve problems caused by putting on a LED when the optical axis of the LED is vertical against the lens face in the illumination part of a game machine. SOLUTION: The depth of an illumination part is made smaller because the optical axis C of LED 65 is almost parallel with a lens 6. Because a flat plane 69 in parallel with the optical axis C and a inclined plane 70 in an angle of 30 deg. against the optical axis C are equipped on the game machine, light L1 outgoing from the LED 65 is scattered and reflected by the flat plane 69 and directed toward the lens 66. Light L2 and light L3 are scattered and reflected by the inclined plane 70 and directed toward the lens 66. Light L4 intercepted by an inner wall 67 is also scattered and reflected and directed toward the lens 66. There is also light L5 directly directed toward the lens 66. Because light irradiated by the LED 65 is extremely efficiently directed toward and passed through the lens 66, the lens 66 can be made extremely brightly irradiate light by a small number of LEDs 65. Because light outgoing from the LED 65 reaches the lens in a mixed condition in random directions, the lens 66 can be made in almost uniform brightness.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention belongs to the technical field of gaming machines.

[0002]

2. Description of the Related Art Illuminations are frequently used in gaming machines such as pachinko machines and slot machines. An ordinary illuminator includes a light-transmitting plastic member (commonly called a lens) provided with knurls, embosses, and the like, and a light source such as a light emitting diode (LED) or a light bulb disposed behind the member. Thus, the illumination effect was obtained by light emitted from the light source, transmitted through the lens, and emitted to the surface side.

[0003]

In the conventional illuminations, the light source is arranged in such a manner that the central axis (optical axis) of the light emitted from the light source is at an angle perpendicular to or nearly perpendicular to the lens surface. There were the following problems.

[0004] First, the length of the LED or the bulb affects the depth dimension of the illuminated part, and this depth dimension is large. Also,
The installation place of the illuminated part may be limited in that relation,
The degree of freedom in design was small. Next, since the light emitted from the light source spreads in a conical shape centered on the optical axis (especially remarkable for LEDs), the range in which one light source illuminates the lens is narrow (spots), and it illuminates a large area. Required a large number of light sources. In addition, if the number of light sources is smaller than the area of the lens, there is a problem that a difference in brightness occurs between the lens surfaces, making it difficult to see. Alternatively, in order to illuminate a larger area with one light source, the distance between the lens and the light source must be increased, which has been a factor of increasing the depth dimension.

[0005] An LED, particularly a white LED, is a remarkable problem, but has a problem of color unevenness. A white LED is a blue LED to which a fluorescent agent that emits yellow light is added, and an element serving as a light source (more precisely, a light emitting diode)
Is blue. The blue light is used to excite the fluorescent agent to emit yellow light, and white light is obtained by the synthesis. Therefore, uneven color (for example, blue or pink) is generated in each LED due to manufacturing variations. However, at present, it is extremely difficult to eliminate the color unevenness. For this reason, if the light of the white LED is directly applied to the lens, the emission color of each LED is directly reflected on the lens, and the color does not become uniform. Even with LEDs of other colors, color unevenness cannot be prevented at all, and sometimes the same problem as with white LEDs may occur.

[0006]

Means for Solving the Problems and Effects of the Invention
The gaming machine described in the gaming machine equipped with a light source that is a light emitting diode or a light bulb, and an illuminated part including a radiating member that transmits light originating from the light source incident from the back side and radiates to the front side, The light source is arranged in such a position that its optical axis does not face the radiating member, and an optical path changing means for changing a path of light emitted from the light source in a direction toward the radiating member is provided.

A light emitting diode or a light bulb serving as a light source is
The optical axis is not oriented toward the radiation member, for example, the optical axis is perpendicular to the axial direction of the radiation member, and the optical axis is arranged so as to be separated from the radiation member at the distal end side. Since the light emitted from the light source spreads conically around the optical axis, most of the light, particularly the portion where the light intensity is high near the optical axis, does not face the radiation member.

[0008] However, the light emitted from the light source is changed its path toward the radiation member by the optical path changing means, enters from the back side of the radiation member, passes through the radiation member, and is emitted from the front side. At this time, if the radiating member is colored, radiated light therefrom becomes colored light.

A light emitting diode or a light bulb serving as a light source is
The optical axis is not parallel to the axial direction of the radiating member (an angle perpendicular or nearly perpendicular to the surface of the radiating member), but is arranged, for example, along the surface of the radiating member. Does not affect the depth dimension of the illuminated part,
The depth dimension can be reduced. In addition, it is avoided that the installation location of the illuminated part is limited due to the depth dimension, and the degree of freedom in design is increased.

The light emitted from the light source spreads in a conical shape centered on the optical axis. The light is not directly incident on the radiation member but is incident on the radiation member by changing its course by the optical path changing means. Therefore, spots are unlikely to occur. In addition, since light emitted from one light source can be diffused over a wide range, a wide range can be irradiated with a small number of light sources.

With respect to the problem of spots and the problem of color unevenness, the structure of claim 2 is effective. The optical path changing means may be configured to change the path of light by reflection or scattering, for example, a reflecting surface (Claim 3), a reflecting surface having a part or all as a scattering reflecting surface (Claim 5), or a light-transmitting synthetic resin. A scattering member in which a reflecting material (for example, a white pigment) is dispersed (Claim 6)
Etc. can be adopted. Further, a material such as a light guide plate of a liquid crystal backlight can also be used.

According to a second aspect of the present invention, in the gaming machine according to the first aspect, the direction of change of the course by the light path changing means is non-uniform depending on an incident position or an incident direction on the light path changing means. It is characterized by the following. By making the direction of change of the path of the light from the light source non-uniform (random) depending on the incident position or incident direction on the optical path changing means, 1
The light emitted from the light sources can be diffused over a wide range, and the light amount is averaged as a whole, so that no spot is generated.

Thus, even if the number of light sources is smaller than the area of the radiating member, there is no difference in brightness between the radiating member and it is not unsightly. Further, since a wide range can be irradiated with a small number of light sources, the number of light sources can be reduced.
Further, by making the course change at random, a plurality of L
Since the light derived from the ED can be made to enter the radiation member in a mixed state, the color of each LED is not reflected on the radiation member as it is, and the color can be made uniform.

According to a third aspect of the present invention, in the gaming machine according to the first or second aspect, the light path changing means is provided with a reflection surface for reflecting light emitted from the light source toward the radiation member. It is characterized by the following. Providing the reflecting surface does not complicate the structure. In addition, for example, by using the inner surface of a casing or the like that houses the LED or the bulb behind the radiating member as a reflecting surface, the structure can be prevented from becoming complicated.

The reflecting surface is not preferable to be a mirror surface in order to diffuse the light from the light source widely and to improve the measures against spots.
For example, a surface state obtained by injection-molding a synthetic resin containing a pigment (the pigment functions as a diffuse reflection material) is sufficient. Of course, the surface may be roughened, or fine powder such as a pigment may be attached to the reflection surface. Further, light-colored paper such as white can be attached to the inner surface of a casing or the like to be used as a reflection surface.

The reflecting surface may be, for example, a plane arranged in a direction parallel to the optical axis. However, as described in claim 4, in the gaming machine according to claim 3, a part or all of the reflecting surface is
It is more effective if the angle between the light source and the optical axis is an acute angle.

When a part is formed as an inclined surface, a portion substantially parallel to the optical axis (hereinafter, referred to as a “flat surface”) is provided on the side closer to the light source, and the side farther from the light source is formed as an inclined surface.
A part of the light emitted from D or the bulb in a conical shape (the part directed toward the flat surface side from the optical axis) is reflected by the flat surface toward the radiation member, and the light near the optical axis is reflected by the inclined surface. Then, the light from the light source can be efficiently directed to the radiation member.

Further, it is also possible to make the entire surface be an inclined surface. In this case, too, the light from the light source can be reflected by the inclined surface and directed to the radiation member. A plurality of inclined surfaces may be provided, for example, in a saw-tooth shape, or only one surface may be provided.

In order to efficiently direct the light from the light source to the radiating member, the top of the inclined surface may be set to be at the same level as the optical axis or closer to the radiating member than the optical axis. In addition, if it is not necessary to supply light or it may be dark on the back side of the inclined surface, the inclined surface may be provided up to a position in contact with the radiation member.

According to a sixth aspect of the present invention, a scattering member in which a reflecting material is dispersed in a light-transmitting synthetic resin can be used as the optical path changing means. 8. The powder according to claim 7, as a reflector, for example, a white pigment (for example, fine powder of titanium oxide).
Is preferred, but not limited thereto. The synthetic resin can be used without any particular limitation as long as it is translucent (preferably transparent or almost transparent), and examples include acrylic resin and polycarbonate. The reflecting material may be dispersed in such a resin by so-called kneading. Note that, since a plate material in which titanium oxide powder is dispersed in acrylic is commercially available, for example, under the name of “white diffusion acrylic”, such a material may be used.

In the case of the scattering member according to the sixth or seventh aspect, most of the light from the light source is reflected on the surface or inside the portion not deep from the surface, depending on the density of the reflecting material. Since the reflecting material such as powder is dispersed, the path of the reflected light is very randomly diffused depending on the incident direction and the incident position on the reflecting material. However, since it is radiated from the surface as a whole,
The light from the light source can be efficiently directed to the radiation member.

According to an eighth aspect of the present invention, in the gaming machine according to any one of the first to seventh aspects, a wall surface along an axial direction of the radiating member is provided on a back side of the radiating member, and the light source is provided. The optical axis is arranged so as to be perpendicular to the wall surface.

By providing such a wall surface on the back side of the radiation member, light from the light source can be reflected on the wall surface and directed to the radiation member, so that light can be used efficiently. In this case, if the wall surface is made of, for example, the same material as the scattering member according to claim 6 or 7 (or a material having the same scattering reflection), the effect of reflection by the wall surface is improved.

Since the radiated light from the LED or the light bulb spreads conically around the optical axis, if the light source is arranged in such a position that the optical axis is perpendicular to the wall surface, a part of the light in the spread part is Many parts are directed to the radiating member by the optical path changing means (such as a reflection surface) as described above, and the light incident on the wall faces to the radiating member as described above. It can be directed to the radiation member very efficiently. Therefore, the number of light sources can be further reduced. The wall surface can also be used to hold a light source.

Next, an embodiment of the present invention will be described with reference to an embodiment of the present invention.

An out hole 48 is provided at the bottom. Although not shown, well-known obstacle nails, windmills, and the like are attached to the game area 21.

The pachinko machine 1 has a horizontally long lamp 12a,
12b, large lamps 13a, 13b and side decorations 46a,
There is a characteristic in the mounting posture of the LED built in 46b, and the like will be described. As shown in FIG. 1, in the horizontally long lamps 12a and 12b, the LED 61 is installed horizontally with the axis substantially horizontal and the rear end at the center lamp 11 side, and the LED 65 of the large lamps 13a and 13b is oriented vertically with the axis almost vertical. It is installed in. In addition, as shown in FIG. 2, in the side decorations 46a and 46b, the LEDs 51 arranged vertically are installed so as to face each other (the light emitted from one goes toward the other). In each case,
The optical axes of the LEDs 61, 65, and 69 are parallel to the surface of the game board 5. In FIG. 1, the lens 66 of the horizontally long lamp 12a and the large lamp 13a is shown, and in FIG.
The lens 54 of 6a is shown in a detached state.

The sectional structure of the large lamps 13a and 13b along the axis of the LED 65 is as shown in FIG. The cross-sectional structure of the horizontally long lamps 12a and 12b along the axis of the LED 61 is substantially the same as FIG. 3 except for the dimensional relationship. Thus, the structure of the large lamps 13a and 13b will be described with reference to FIG. 3, and the description of the horizontally long lamps 12a and 12b will also be given.

As shown in FIG. 3, the large lamps 13a, 13a
b (horizontally elongated lamps 12a and 12b), a concave portion 60 is provided in the glass holding frame 6a.
(61) is accommodated. The glass holding frame 6a is a plastic (for example, polycarbonate) colored with a light-colored pigment (for example, white pigment), and the recess 60 is also made of the same material. The recess 60 corresponds to a scattering member.

The concave portion 60 is not visible to a player in a state where the concave portion 60 is covered with a lens 66 corresponding to a radiation member. The lens 66 is made of colored translucent plastic, and has irregularities (not shown) such as knurls, for example, and has a function of scattering light transmitted therethrough.

The concave portion 60 has an inner wall 67 to which the edge portion of the lens 66 is fitted and adhered and a bottom portion 68 facing the lens 66.
It consists of The terminal pins of the LEDs 65 (61) are soldered to a printed board 64 disposed behind the inner wall 67, and the LEDs 65 (61) are connected by wiring (not shown).
Can be supplied with power.

The bottom 68 is composed of a flat surface 69 near the LED 65 (61) and an inclined surface 70 farther from the LED 65 (61). In design, the flat surface 69 is parallel to the optical axis C of the LED 65 (61), and the angle between the inclined surface 70 and the optical axis C is 30 degrees.

When the LED 65 (61) is turned on, LE
The light from D65 (61) spreads conically around the optical axis C. However, the amount of light increases near the optical axis C and decreases as the distance from the vicinity increases. Assuming such a light cone, the light L1 near the side surface enters the flat surface 69. Since the flat surface 69 is made of a plastic containing a light-colored pigment, incident light is scattered and reflected by the action of the fine powder of the pigment, and is generally directed to the lens 66, and a part of the light is directed to the inclined surface 70. is there.

The optical axis C is higher than the light L1 incident on the flat surface 69.
The approaching light L2 and the light L3 near the optical axis C strike the inclined surface 70. Also, the inclined surface 7 after being reflected by the flat surface 69.
Some light hits zero. In any case, the light that hits the inclined surface 70 is also scattered and reflected here and goes to the lens 66.

Further, the light L4 that hits the inner wall 67 on the opposite side of the LED 65 (61) without hitting the flat surface 69 or the inclined surface 70 is also scattered and reflected toward the lens 66 or the inner wall on the LED 65 (61) side. There are things going to 67 and so on. In FIG. 3, the light L1, L2, L
3, L4 is shown to be scattered in multiple directions at one point, but this is for the sake of simplicity of explanation, and in fact, the reflection direction is variously varied depending on a slight difference in the incident position and the incident angle. The result is scattered reflection.

Alternatively, there is light L5 that directly goes to the lens 66 without going to the inner wall 67, the flat surface 69, and the inclined surface 70. As described above, the light emitted from the LED 65 (61) is scattered and reflected by the inner wall 67, the flat surface 69, and the inclined surface 70 or directly goes to the lens 66. Also, there is light that is scattered and reflected on the inner wall 67, the flat surface 69, and the inclined surface 70, and then reflected on the inner wall 67 and the like again without going to the lens 66.
Those will eventually go to the lens 66. That is,
Most of the light emitted from the LED 65 (61) goes to the lens 66.

The light incident on the lens 66 passes therethrough, but is scattered and emitted in random directions by, for example, knurls and the like, and reaches the eyes of the player. Thus, LED
65 (61) is very efficiently directed to and transmitted through the lens 66 so that a small number of LEDs
65 (61) very good (bright) lens 66
Can shine.

Further, most of the light emitted from the LED 65 (61) does not directly go to the lens 66 (61),
Then, the light reaches the lens 66 after being scattered and reflected inside 0. That is, the light emitted from the LED 65 (61) reaches the lens 66 from random directions and in a mixed state. Therefore, unlike the case where the optical axis C of the LED 65 (61) is arranged in a matrix or a row with the optical axis C perpendicular to the lens 66, no light intensity (spot) is generated on the light emitting surface of the lens 66. The brightness of the lens 66 can be made substantially uniform.

Further, since the light emitted from the plurality of LEDs 65 reaches the lens 66 in a state of being mixed, the color unevenness and the brightness unevenness of each LED 65 are not reflected on the lens 66, and are extremely uniform on the lens 66. Luminescent color is obtained, and there is no uneven brightness. This effect is particularly advantageous when using an LED having remarkable color unevenness and luminance unevenness such as a white LED.

Next, the LEDs 5 of the side decorations 46a and 46b
The side decorations 46a and 46b will be described with reference to FIG. 4 showing a cross-sectional structure along one axis. Side decoration 46a,
The surface 46b (the surface visible to the player) is the lens 54 corresponding to the radiation member. Transparent and colored lens 5
The surface 4 is provided with irregularities such as knurls (not shown), and has a function of scattering light transmitted therethrough. The lens 54 is integrated with the substrate 56 via the peripheral wall 55, and is attached to the game board 5 at the substrate 56.

A housing 53 made of white polycarbonate is accommodated inside a box-shaped portion formed by the lens 54 and the peripheral wall 55. The housing 53 corresponds to a scattering member. The housing 53 includes an inner wall 57 having a shape along the peripheral wall portion 55, a flat surface 58 facing the lens 54, and an inclined surface 59.

A printed board 77 is mounted behind the inner wall 57, and the LED 51 is mounted by soldering terminal pins to the board 77, and power can be supplied to the LED 51 by wiring (not shown). The LED 51 on the opposite side is attached in the same manner, but as described above, both LEDs 51 are in a posture facing each other.

The ridge 73 formed by the inclined surface 59
Is substantially at the middle of the two LEDs 51 and is orthogonal to their optical axis C, and the structure of the housing 53 is substantially symmetric about the ridge 73. The optical axis C of the LED 51 is a flat surface 5.
8 and an angle between the inclined surface 59 and the inclined surface 59 is set to an acute angle (about 30 degrees in this example).

When the LED 51 is turned on, the light from the LED 51 spreads conically around the optical axis C. However,
The amount of light increases near the optical axis C and decreases with increasing distance therefrom. Assuming such a light cone, the light L1 near the side surface enters the flat surface 58. Its flat surface 58
Is white polycarbonate, the incident light is scattered and reflected by the action of the fine powder of the white pigment contained therein, and generally the light goes to the lens 54 and some light goes to the inclined surface 59.

The optical axis C is higher than the light L1 incident on the flat surface 58.
The approaching light L2 and the light L3 in the optical axis C portion impinge on the inclined surface 59. In addition, after being reflected by the flat surface 58, the inclined surface 5
Some light hits 9. In any case, the light that hits the inclined surface 59 is also scattered and reflected here and goes to the lens 54.

In FIG. 4, the light L1, L2, L3
Is shown to be scattered in multiple directions at one point, but this is for the sake of simplicity of explanation, and in fact, the reflection direction is variously varied depending on slight incident positions and incident angles, and as a result, It becomes scattered reflection.

Further, there is also light L4 which goes directly to the lens 54 without going to the flat surface 58 or the inclined surface 59. In addition, some light is reflected by the inner wall 57 and the like, and such light is directed toward the lens 54 directly or after being reflected by the flat surface 58 or the inclined surface 59. That is, most of the light emitted from the LED 51 goes to the lens 54.

The light incident on the lens 54 passes therethrough, but is scattered and emitted in random directions by, for example, knurls, and reaches the eyes of the player. Thus, LED
Since the light radiated from the light 51 is directed to the lens 54 very efficiently and transmitted therethrough, even a small number of LEDs 51 can make the lens 54 shine very well (brightly).

Further, most of the light emitted from the LED 51 does not directly go to the lens 54 but is scattered and reflected inside the housing 53 before reaching the lens 54. That is,
The light emitted from the LEDs 51 reaches the lens 54 from random directions and in a mixed state. For this reason,
Unlike the case where the optical axis C of the LED 51 is arranged in a matrix or a row with the optical axis C perpendicular to the lens 54, the intensity of light (spot) does not occur on the light emitting surface of the lens 54, and the lens 54 is substantially even. Brightness can be made.

Further, since the lights emitted from the plurality of LEDs 51 reach the lens 54 in a mixed state, the color unevenness and the brightness unevenness of the individual LEDs 51 are not reflected on the lens 54, and are extremely uniform on the lens 54. Luminescent color is obtained, and there is no uneven brightness. This effect is particularly advantageous when using an LED having remarkable color unevenness and luminance unevenness such as a white LED.

As described above, the pachinko machine 1 of this embodiment
Are horizontal lamps 12a and 12b, large lamps 13a and 13
b and LEDs incorporated in the side decorations 46a and 46b
By making the optical axis C of 61, 65, 51 parallel to the game board 5, the optical axis C does not face the lenses 66, 54, which are radiating members, and the light emitted from the LEDs 61, 65, 51 The concave portion 60 and the housing 53 are provided as optical path changing means for changing the course in the direction toward the lenses 66 and 54.

The light emitted from the LEDs 61, 65, 51 spreads conically around the optical axis C, but does not directly enter the lenses 66, 54. Surfaces 70 and 59 and flat surfaces 69 and 5
Since the path is changed by 8) and the light is incident on the lenses 66 and 54, spots hardly occur. Also one LED6
Light emitted from 1, 65, and 51 can be diffused over a wide range, so that a wide range can be irradiated with a small number of LEDs.

In particular, since a portion near the optical axis C where the light intensity is high does not go to the lenses 66 and 54, spots can be prevented very well. LEDs 61, 65, 51
Since the optical axis C is arranged parallel to the game board 5 (in the direction along the surfaces of the lenses 66 and 54), the LEDs 61, 65,
The horizontally long lamps 12a, 12b, each of which has a length of 51 as an illumination part,
The depth dimension of the large lamps 13a, 13b and the side decorations 46a, 46b is not affected, and the depth dimension can be reduced. In addition, it is avoided that the installation location of the illuminated part is limited due to the depth dimension, and the degree of freedom in design is increased.

The reflection by the concave portion 60 and the housing 53 (particularly, the inclined surfaces 70 and 59 and the flat surfaces 69 and 58) serving as the optical path changing means is extremely non-uniform (random) depending on the incident position or the incident direction. LED61, 6
Light emitted from 5, 51 can be diffused over a wide range, and the amount of light is averaged as a whole, so that no spot is generated.

Thus, even if the number of the LEDs 61, 65, 51 is smaller than the area of the lenses 66, 54, there is no difference in brightness between the lenses 66, 54, so that it is not unsightly. Further, since a wide range can be irradiated with a small number of LEDs 61, 65, and 51, the number of LEDs can be reduced.

Further, by making the course change at random by scattering reflection, light originating from the plurality of LEDs 65 and 51 can be made to enter the lenses 66 and 54 in a mixed state. Are not reflected on the lenses 66 and 54 as they are, and a uniform color can be obtained.

Since the recess 60 and the inner surface of the housing 53 are reflection surfaces, the structure is not complicated. In addition, the concave portion 60 serving as a reflection surface and the inner surface of the housing 53 are provided with an LED 6
The inclined surfaces 70 and 59 at which the angles between the optical axes C of 1, 65 and 51 are acute are provided, and the flat surfaces 69 and 58 are provided more than the LEDs 61, 65 and 51.
A part of the light emitted in a conical shape from the light-emitting elements 5 and 51 (portion toward the flat surfaces 69 and 58 with respect to the optical axis C) is flat surfaces 69 and 5.
8 is directed toward the lenses 66 and 54, and the light near the optical axis C is reflected by the inclined surfaces 70 and 59 and travels toward the lenses 66 and 54, so that the light from the LEDs 61, 65 and 51 can be efficiently reflected by the lenses. 66, 54.

The recess 60 is made of plastic containing a light-colored pigment, and the housing 53 is made of white polycarbonate. Therefore, the path of reflected light is diffused very randomly depending on the direction of incidence and the position of incidence on these. Moreover, light from the LEDs 61, 65, 51 can be efficiently directed to the lenses 66, 54 as a whole.

Further, the inner walls 67 and 57 along the axial direction of the lenses 66 and 54 are provided on the back surface side of the lenses 66 and 54, and the LEDs 61, 65 and 51 are arranged so that the optical axis C is
Since it was arranged in a posture almost perpendicular to 7 and 57, LED6
Light from 1, 65, 51 can also be reflected by inner walls 67, 57 and directed to lenses 66, 54. In this way, the light of the LEDs 61, 65, 51 can be used efficiently, and the number of the LEDs 61, 65, 51 can be further reduced. The inner walls 67 and 57 can also be used to hold the LEDs 61, 65 and 51.

Although the embodiments of the present invention have been described with reference to the examples, the present invention is not limited to these examples. For example, in the embodiment, the inclined surfaces 59 and 70 are provided. However, the inclined surfaces 59 and 70 may not be provided and only the flat surface may be provided, or almost the inclined surface may not be provided (or reduced). Further, the optical axis of the LED may not be parallel to the flat surface but may be a direction toward the flat surface.
