It is difficult.

[0004]

SUMMARY OF THE INVENTION In view of the above problems, it is an object of the present invention to provide an illumination device for a gaming machine, which can emit light of a single color or mixed colors in a beautiful manner.

[0005]

According to a first aspect of the present invention for solving the above-mentioned problems, a first light-emitting body is arranged on at least one end surface of a light guide rod, and light transmitted through the light guide rod. A first light-emitting device that refracts and emits light on its peripheral surface, and a second light-emitting device that is disposed on the back side of the light guide rod and is separated from the second light-emitting body that emits light toward the light guide rod. It is characterized by consisting of.

In the case of the first aspect of the invention, the peripheral surface of the light guide rod is refracted and emitted by the first light emitter disposed on at least one end surface. In addition, the light guide rod is also emitted by the second light emitter disposed on the back side thereof at a distance.
In this way, the light guide rod can be caused to emit light by the first and second light emitters, and the electric decoration effect of the gaming machine can be enhanced.

The invention according to claim 2 is based on the invention according to claim 1, and is characterized in that the first light emitter and the second light emitter can emit light in different emission colors. There is. That is, the peripheral surface of the light guide rod emits a single color by the light from any one of the light emitters. In addition, the light guide rod emits light in a mixed color by causing the first and second light emitters to emit light at the same time. As a result, the light guide rod can emit light of a single color or a mixed color. Moreover,
By switching the first and second light emitters, it is possible to make the player feel a light emitting state with a sense of depth, and it is possible to remarkably enhance the lighting effect of the gaming machine.

The invention described in claim 3 is the invention according to claim 1 or 2.
On the premise of the invention described in (1) above, a large number of recesses are provided on the outer peripheral surface of the light guide rod. Light is emitted from the first light emitter disposed on one end surface of the light guide rod,
The light incident on the one end surface of the light guide rod goes straight toward the other end surface. When this light reaches each of the concave portions provided on the outer peripheral surface of the light guide rod, the light is refracted at the corresponding portion. Therefore, the player recognizes that only each recess is emitting light. Further, the light guide rod is caused to emit light by the light emitted toward the light guide rod from the second light emitter of the second light emitting device which is arranged on the back side of the light guide rod at a large distance. In each recess of the light guide rod, the light from the first light emitter and the two types of light from the second light emitter are mixed and emitted. For this reason, for example, in the case of mixed color light emission with different emission colors, compared to mixed color light emission of two kinds of light emitted in the same plane portion or in a state close to the same plane portion, mixed color light emission is performed in the three-dimensional space portion. The existence of the two types of emission colors becomes clear, and the effect of mixed color emission is enhanced.

The invention according to claim 4 is based on the invention according to claim 3, wherein the recesses are cut grooves provided at predetermined intervals in the longitudinal direction, and the depth of the cut grooves is large. Is characterized in that the depth gradually increases as the distance from the first light-emitting body arranged on one end surface of the light guide rod increases. Therefore, the light incident from the one end surface of the light guide rod is emitted only at the groove bottom portion of each cut groove of the light guide rod. As a result, the mixed-color light emitting state of the light guide rods can be scattered in the longitudinal direction, and the light emitting state becomes clearer.

The invention according to claim 5 is based on the invention according to any one of claims 1 to 4, wherein the first light emitting device includes a plurality of light guide rods arranged in parallel with each other. The light guide rods are characterized in that they sequentially emit light along their arrangement direction. Therefore, it is possible to change the light emission state of each light guide rod by sequentially and continuously emitting light of a single color or a mixed color or differentiating the light emission color of each light guide rod.

The invention according to claim 6 is based on the invention according to any one of claims 1 to 5, and emits light from the second light emitter between the light guide rod and the second light emitter. It is characterized in that a diffusion lens for diffusing the reflected light is arranged. Therefore, the light emitted from the second light emitter is diffused by the diffusion lens and reaches the entire area of the light guide rod. As a result, even if the number of the second light emitters is small, it is possible to cause the entire light guide rod to emit light substantially uniformly, and the mixed color emission state does not become uneven.

As shown in FIGS. 2 to 4, the illumination device A ₁ mainly includes a front side light emitting device B arranged in a front portion (front side) of the housing 1.
₁ , a rear side light emitting device B ₂ which is also arranged at the rear part (back side), and a diffusion lens 3 which is arranged between the two.

First, the front side light emitting device B ₁ will be described. As shown in FIGS. 3 to 5, the front side light emitting device B ₁ includes a plurality of (five in the present embodiment) light guide rods 2.
And upper and lower light emitter units Ca and Cb arranged above and below them. Each light guide rod 2 of this embodiment
Are arranged in an arc shape in a plan view, and are attached with their axes along the vertical direction. Since the configuration of each light guide bar 2 is the same, only one of them will be described. As shown in FIG. 6, the light guide bar 2 is made of an acrylic resin having excellent light transmittance, has a constant thickness over the entire length, and has a large number of cut grooves on its outer peripheral surface (side surface). Four
Are provided at a constant pitch. The cross section of each of these cut grooves 4 is V-shaped, and the depth thereof gradually increases from the upper and lower end surfaces 2a, 2b of the light guide rod 2 toward the center thereof. . In other words, the cross-sections of the large number of cut grooves 4 are similar to each other, and gradually become similar in size from both end faces 2a, 2b of the light guide bar 2 toward the center thereof. The light guide bar 2 is arranged so that the cut groove 4 faces the front surface (the player's side). The angle θ formed by the groove surfaces 5 of the cut groove 4 is such that the light transmitted through the light guide rod 2 is not totally reflected at the cut groove 4 and a part thereof is air. It is set to the angle that is refracted inside.

As shown in FIGS. 3 to 5, an upper support plate 6a and an upper light emitter unit Ca are arranged above each light guide bar 2, and similarly, a lower support is provided below. The plate 6b and the lower light emitter unit Cb are arranged.
Here, the members arranged on the upper side of the light guide rod 2 are described by adding the suffix “a” to the reference numerals, and the members arranged on the lower side are described by adding the suffix “b” to the same reference numerals. . Each light guide rod 2 arranged in an arc shape in a plan view is supported by upper and lower support plates 6a and 6b each having a semicircular front portion. That is, five insertion holes 7a and 7b are provided in the front portion of each of the support plates 6a and 6b along the circumferential direction. Each insertion hole 7a, 7b
The inner diameter of is slightly larger than the outer diameter of the light guide rod 2. Then, the upper and lower end portions of each light guide bar 2 have corresponding insertion holes 7a, 7
It is inserted into b. By doing this, each light guide rod 2
Is held by the upper and lower support plates 6a, 6b in the circumferentially arranged state.

Next, the upper and lower light emitter units Ca and Cb will be described. The upper and lower light emitter units Ca and Cb are
Only the upper and lower light emitting units Ca have the same configuration except that they are arranged in opposite directions. The upper substrate 8a forming the upper light emitter unit Ca is attached to the upper surface of the upper support plate 6a described above, and has a substantially similar shape that is slightly smaller than the upper support plate 6a. Then, five LEDs constituting the first light emitting body 10 are attached to portions of the upper support plate 6a corresponding to the respective insertion holes 7a. In the upper light emitter unit Ca of the present embodiment, the red LED (Dred) is attached downward at the front end portion (center portion) thereof. Then, on both sides of the red LED (Dred), the yellow LEDs (Dye) are equally spaced in the circumferential direction on the same circumference.
llow) and each blue LED (Dblue) are mounted downward. That is, right above and below the light guide rod 2 in the center, the red LE is opposed to the upper and lower end faces 2a and 2b.
D (Dred) is arranged, yellow LEDs (Dyellow) are arranged in the same manner on the two light guide rods 2 on both sides thereof, and two light guide rods 2 on both ends are arranged. Similarly, a blue LED (Dblue) is arranged. Each LED (D
When blue, Dred, and Dyellow) are emitted toward the light guide rods 2, the cut grooves 4 of the light guide rods 2 emit light in respective colors.

Next, referring to FIG. 7, the light guide rod 2 is described.
The principle of light emission will be described. A light ray L that is vertically incident on the upper end surface 2a of the light guide rod 2 goes straight through the inside of the light guide rod 2 and goes out into the air from the lower end surface 2b. Here, of the incident light rays L, the light rays L passing through the portion of the cut groove 4 are refracted by the groove surface 5 and go out into the air. That is, it is refracted at one of the groove surfaces 5 constituting the cut groove 4 and is refracted in the air (cut groove 4
The light ray L that has emerged on the other groove surface 5 is reflected by the other groove surface 5,
Proceed in a direction recognizable by the player.

Here, since the large number of cut grooves 4 are formed so that the depth thereof gradually increases from the end portion of the light guide rod 2 toward the central portion thereof, the adjacent cut grooves 4 are formed. Between them, a predetermined difference e is generated with respect to the depth. Therefore, the light ray L that is vertically incident on the upper end surface 2a of the light guide rod 2 and enters the inside thereof reaches all the cut grooves 4, and the light refraction phenomenon occurs on the groove surface 5. That is, with respect to the cut groove 4 closest to the upper end surface 2a of the light guide rod 2, the above-described light refraction phenomenon occurs on the entire surface of the groove surface 5, and at the other cut grooves 4, the groove surface 5 is formed. The above-mentioned light refraction phenomenon occurs only in the portion (groove bottom portion) corresponding to the depth difference e between the adjacent cut grooves 4. As a result, in all the cut groove portions 4,
A light refraction phenomenon occurs due to the light ray L passing through the light guide rod 2, the illuminance of all the cut grooves 4 becomes higher than that of other portions, and light is scattered in a substantially uniform state. The light refraction phenomenon is also caused by the light ray L incident from the lower end surface 2b of the light guide rod 2. In the case of the illumination device A ₁ of the present embodiment, the synergistic action of the two light rays L incident from the upper and lower end surfaces 2a and 2b causes the cut groove 4 to emit light more clearly. In addition, in FIG. 7, L'is each cut groove 4
A ray of light that is not refracted at the groove surface 5 but is reflected in the light guide rod 2 and is then refracted to go outside (in the air) from a portion other than the cut groove 4 is shown.

As shown in FIG. 6, the front shape of each cut groove 4 provided in the light guide bar 2 is an elliptical shape, and the size thereof gradually increases from both end faces toward the central portion. It is getting bigger. Therefore, of the many cut grooves 4, the two cut grooves 4 provided at both ends in the longitudinal direction of the light guide rod 2 emit light in an elliptical shape close to the front shape thereof, and the remaining cut grooves 4 have the same shape. Only the part of the bottom of the groove emits light. Therefore, the light emission width of the remaining cut grooves 4 is substantially constant, but the length thereof is a horizontally long rectangular shape gradually increasing from both ends toward the center.
Therefore, when observing the entire light emitting state of the light guide rods 2 from the front surface (the player's side), a large number of light emitting portions are scattered in a vertically aligned state.

Next, the rear light emitting device B ₂ will be described. As shown in FIGS. 3 to 5, the front side light emitting device B
The rear light-emitting device B ₂ is arranged on the back side of each light guide rod 2 constituting ₁ with a predetermined distance. The rear substrate 9 that constitutes the rear light emitting device B ₂ is large enough to cover almost all of the light guide rods 2, and is provided on the front surface (side facing each light guide rod 2). , A large number (10 in the present embodiment) of red LEDs constituting the second light emitter 20
(Dred) over the entire area and adjacent red LE
The distance from D (Dred) is almost the same. Then, the light emitted from each red LED (Dred) is incident substantially at right angles to the longitudinal direction of each light guide rod 2.

A diffusing lens 3 is attached between each light guide rod 2 and the rear light emitting device B ₂ . The diffusion lens 3 is almost the same size as the rear substrate 9 of the rear light emitting device B _2, from the red LED is the second light emitter 20 composing the rear light emitting device B ₂ (Dred) It has a function of diffusing the emitted light and causing the whole of each light guide bar 2 to emit light. Therefore, the light emitted from each red LED (Dred) of the rear light-emitting device B ₂ reaches the entire light guide bar 2, and the entire light guide bar 2 has substantially the same illuminance and is evenly distributed. The light is emitted. A front lens 11 is provided on the front surface of each light guide bar 2 to more clearly reflect the light emitting state of each light guide bar 2 and to protect each light guide bar 2. In addition, in FIG. 3, 12a and 12b are
These are caps for holding the front lens 11.

The operation of the illumination device A _{1 according} to the present invention will be described with reference to FIGS. 8 to 10. At first,
The case where the blue LED (Dblue) among the LEDs (Dblue, Dred, Dyellow) that are the first light emitters 10 constituting the upper and lower light emitter units Ca and Cb is independently emitted, and the rear light emitting device B _{The case} where each red LED (Dred) which is the second light emitting body 20 constituting ₂ is independently caused to emit light will be described, and then the case where these are simultaneously emitted will be explained. As described above, the upper and lower light emitter units Ca, C
The blue LED (Dblu) which is the first light-emitting body 10 that constitutes b
From e), the blue light Lblue emitted toward the upper and lower end surfaces 2a, 2b of the light guide rod 2 goes straight inside the light guide rod 2 as it is. Then, after being refracted at the groove surface 5 on one side of each of the cut grooves 4 and being exposed to the air (the portion of the cut groove 4),
It is reflected by the groove surface 5 on the other side.

Here, the depth of each of the cut grooves 4 is provided so as to gradually increase from the end portion of the light guide rod 2 toward the central portion in the longitudinal direction. Therefore, the actual light-emitting source is the first light-emitting body (LE) that constitutes each light-emitting body unit Ca, Cb provided on the upper and lower end surfaces 2a, 2b of the light guide rod 2.
D) Even though only 10 is present, the player feels that all the cut groove portions 4 are emitting blue light. In addition, a large number of cut grooves 4 provided in each light guide rod 2
Is gradually increased in depth from both ends thereof toward the central portion, and two blue L's arranged opposite to both end faces 2a, 2b thereof are provided.
Since each blue light Lblue from the ED (Dblue) is incident, attenuation of each blue light Lblue reduces the illuminance at the portion of the cut groove 4 which is greatly separated from the upper and lower light emitter units Ca and Cb. This can be prevented, and the difference in the illuminance of a large number of light emitting units that emit light in a straight line can be reduced. Further, since the thickness of each light guide rod 2 is uniform over the entire length thereof, the shape of each cut groove 4 becomes similar, and the shape of the light emitting portion also changes with a certain regularity corresponding thereto. The shape (the emission width is constant as described above, but the length thereof is a horizontally long rectangular shape gradually increasing from both ends toward the central portion), and light is emitted neatly.

When only the rear light-emitting device B ₂ is caused to emit light independently, each red LED (D
The red light Lred emitted from red) is diffused when passing through the diffusion lens 3. Since each light guide bar 2 is excellent in light transmittance, the diffused red light L'red is generated by each light guide bar 2.
Spans the entire area. As a result, the entire light guide rods 2 emit red light in a uniform and uniform state. Even if each red LED (Dred) is attached to the rear substrate 9 of the rear light emitting device B _{2 in} a scattered state, each light guide bar 2 and the rear light emitting device B 2
_{Since a} predetermined distance is provided between the light guide rods 2 and 2, the respective light guide rods 2 can be made to emit light in a beautiful red color. This means that the number of red LEDs (Dred) forming the rear light emitting device B ₂ can be reduced without impairing the advantage that the entire area of each light guide bar 2 emits light neatly.

Next, the upper and lower blue LEDs (Dblue) in the front side light emitting device B ₁ and the respective red color L in the rear side light emitting device B _2.
A case where ED (Dred) is simultaneously emitted will be described. As described above, by making the upper and lower blue LEDs (Dblue) emit light, the cut groove 4 of the corresponding light guide bar 2 is formed.
The portion (groove bottom) emits blue light. Further, by causing each red LED (Dred) of the rear light emitting device B ₂ to emit light, the entire area of each light guide rod 2 is emitted in red. As a result, in the portion of each cut groove 4 in the light guide rod 2, the blue light Lblue and the red light Lred interfere with each other to emit a mixed color of the two, that is, purple.

Here, the upper and lower light emitter units Ca, Cb
Are arranged on the front side (the side close to the player) of the illumination device A ₁ , and the rear light emitting device B ₂ is also arranged on the back side at a large distance. And the front and rear light emitting devices B
_The two types of light emitted from ₁ and B ₂ are mixed in the plurality of cut grooves 4 in each light guide bar 2 and emitted. Here, in the conventional illumination device, light is emitted in the same plane portion or in a state close to the same plane portion. In comparison with this, in the lighting device A _{1 according} to the present invention, mixed color light emission is performed at each light guide bar 2.
In other words, since the mixed color light is emitted in the three-dimensional space portion in the lighting device A ₁ , the existence of the two colors becomes clear, and the player is
A "three-dimensional light emitting state with a sense of depth", which is different from the two-dimensional light emitting state in the conventional illumination device, is felt. Moreover,
The irradiation direction of the light from the first light emitting device B ₁ and the irradiation direction of the light from the second light emitting device B ₂ are orthogonal to each other, and the light on one side does not cause a shadow of the device on the other side. Therefore, each light guide rod 2 emits light in a uniform and clean state. In this way, the electric decoration effect in the pachinko machine P is significantly enhanced.

The above-described lighting device A ₁ of the first embodiment is
This is a case where five light guide rods 2 are arranged in parallel to each other along the circumferential direction. By doing so, it is possible to sequentially and continuously emit light from the light guide rods 2 or to make the light emission colors of the light guide rods 2 different. That is, various changes can be given to the light emitting state of each light guide rod 2. However, the light guide rod 2 may be one. Next, the illumination device A ₂ of the second embodiment will be described. The difference between this illumination device A _{2 and} the illumination device A ₁ of the first embodiment is that there is one light guide rod 2 and that one light-emitting body constitutes the rear light-emitting device B _2. It means that it is a blue LED (Dblue). As shown in FIGS. 11 and 12, guide grooves 14a and 14b facing each other are provided in a circular arc shape at the front portions of the upper and lower support plates 13a and 13b. The groove width of each guide groove 14a, 14b is slightly larger than the outer diameter of the light guide bar 2. Then, the upper and lower guide grooves 14a,
The light guide rod 2 fitted in 14b has upper and lower support plates 13
It is attached so as to be sandwiched between a and 13b. The guide grooves 14a, 14b are provided with light projecting holes 15a, 15b at equal intervals in the circumferential direction on the same circumference. In the portions of these light projecting holes 15a and 15b, red LEDs are respectively provided as in the case of the illumination device A ₁ of the first embodiment.
(Dred), yellow LED (Dyellow), and blue LED
(Dblue) is attached.

An arm 16 is provided at the upper end of the light guide rod 2 so as to extend toward the back side. The arm 16
A first gear 17 is fixedly attached to the rear end portion. The support shaft 18 of the first gear 17 is rotatably supported by a bearing 19. A drive motor 21 is disposed beside the first gear 17, and the first gear 17 meshes with a second gear 22 mounted on a motor shaft 21a of the drive motor 21. There is. Therefore, when the drive motor 21 is operated, the light guide bar 2 is guided by the upper and lower guide grooves 14a and 14b and moved in the circumferential direction. Then, by controlling the drive motor 21, the light guide bar 2 is moved to the guide grooves 14a, 14b.
It is also possible to reciprocate within the area of.

A guide rail 23 is erected on the back side of the light guide rod 2, and a screw shaft 24 is erected on the side of the guide rail 23. The upper end of the screw shaft 24 is connected to a drive motor 26 via a coupling 25. The guide body 2 is attached to the screw shaft 24.
7 is screwed, and the guide body 27 is guided by the guide rail 23. Therefore, when the motor shaft 26a of the drive motor 26 is reciprocally rotated by a certain amount,
The guide body 27 is vertically reciprocated. The guide body 2
On the front end face of 7, a blue LED (Dblue) is attached so that it can emit blue light toward the front. When the moving light guide bar 2 is positioned immediately before the blue LED (Dblue), the blue light emitted from the blue LED (Dblue) is perpendicular to the longitudinal direction of the light guide bar 2. Is incident on.

The operation of the illumination device A ₂ of the second embodiment will be described. The light guide rod 2 is activated by operating the drive motor 21.
Is moved back and forth in an arc shape. Further, the drive motor 26 is operated to reciprocate the blue LED (Dblue) up and down. In this state, the upper and lower LEDs (Dblue, Dred, D
yellow) and the blue LED (Dblue) on the rear side are caused to emit light. The light guide rod 2 is each LED (Dblue, Dred, Dyellow)
When positioned at the portions of the light projecting holes 15a, 15b corresponding to, light is incident on the light guide rod 2 from the upper and lower end surfaces 2a, 2b, and the portions of the cut grooves 4 are emitted. When the light guide bar 2 is moved to a position immediately before the rear blue LED (Dblue) (at this time, the light guide bar 2 emits red light Lred from above and below). Blue LED (Dbl
ue) and the red light Lred from the blue light interfere with each other, and the cut grooves 4 emit light in a mixed color state (purple). Further, by vertically moving the rear guide body 27, the light guide rod 2 can be made to emit light over the entire length. In this way, even if there is only one light guide rod 2,
Almost the same effects as the illumination device A _{1 of the} embodiment are exhibited.

The light guide rod 2 in each of the above-mentioned embodiments is
It is made of transparent acrylic resin and has a large number of cut grooves 4 provided in its longitudinal direction. However, it may be something other than this. For example, it may be a simple rod body that is not provided with the cut groove 4 and that emits linear light. In this case, the rod body emits light in a band shape.

As for the material of the light guide rod 2, any material may be used as long as it has a light-transmitting property. In addition to the above acrylic resin, polycarbonate resin, glass, etc. may be used. Regarding the method of forming a large number of cut grooves 4 in 2, there are a method by cutting, a method of simultaneously forming the cut grooves 4 at the time of molding the light guide rod, and the like.
It can be easily molded.

Further, regarding the shapes of the large number of cut grooves 4 provided in the light guide rod 2, as in the above-described embodiments,
The cross section is not limited to the V-shaped cross section, and the cross section in which the width gradually increases toward the opening may be the irregular U shape.
Further, the depth of the large number of cut grooves 4 formed in each light guide bar 2 may be gradually deepened from one end surface to the other end surface.

The light emitting source in each of the above embodiments is an LED. Therefore, there is an advantage that the brightness can be easily adjusted and the life thereof is long. However, bean balls may be used. In this case, there is an advantage that it is inexpensive. Further, other than that, for example, a cold cathode tube (fluorescent tube) may be used. In this case, there is an advantage that the entire light guide bar 2 can be made to emit light without using the diffusion lens 3.

As described above, the illumination device A according to the present invention
₁ and A ₂ are superior in illumination effect compared to the conventional illumination device, and in addition to being used as a normal illumination device (for example, an illumination device for island equipment), a big hit notice or It can also be used to produce a big hit state. For this reason, it is desirable that the installation place be installed at a position where it can be most effectively shown to the player, that is, on both sides of the symbol display device 56 (see FIG. 1). However, it may be in a position other than this, for example, in the upper part of the center accessory, or another game area.

Further, in each of the above-mentioned embodiments, the electric decoration devices A ₁ and A ₂ are vertically arranged and used, but the electric decoration devices A ₁ and A ₂ may be arranged horizontally or obliquely depending on the device part of the gaming machine. It is also possible to use. Further, the practicable game machine is not limited to the pachinko machine P, but can be practiced for other game machines such as slot machines.
