Technical Field

The present invention relates to a game machine such as a pachinko machine or a slot machine, and a presentation method performed in the game machine.

Background

A game machine such as a pachinko machine or a slot machine is variously shown in order to enhance entertainment. For example, it is known to provide a liquid crystal display on a game board, in which various video images are displayed. In addition, it is also known to apply various decorations to a game board, mount a light source such as an LED on the decoration, and make the decoration emit light.

In recent years, various kinds of displays have been required for game machines, and it has been studied to use a protective glass unit attached to the front surface of a game board, in addition to the game board. For example, patent document 1 discloses that printing or a concave-convex shape is applied to a main surface of a glass unit facing a game board, light from a light-emitting device provided on one surface of the glass unit is reflected on the main surface, and a pattern corresponding to the printing or the concave-convex shape is displayed.

Patent document 1 also discloses a glass unit including a pair of transparent substrates and an electro-optical functional layer sandwiched between the transparent substrates. The electro-optical functional layer transmits light when a voltage is applied, and can scatter light when no voltage is applied. Therefore, by adjusting whether or not a voltage is applied, characters and a screen can be displayed on the glass unit.

Detailed Description

[ Structure and representation of Game machine ]

Hereinafter, the structure of a game machine and a display on a glass unit according to the present invention will be described in detail with reference to the drawings in embodiments 1 to 4.

(embodiment 1)

Fig. 1 is a perspective view for explaining an example of a game machine.

The game machine 10 includes a housing 11, a game board 12 disposed inside the housing 11, and a front cover 13 attached to the front surface of the game board 12. The front cover 13 is disposed to close the open front surface of the housing 11 and is openably and closably attached to the housing 11.

The front cover 13 includes a frame 14 and a glass unit 15, and the glass unit 15 is disposed so as to be fitted into the frame of the frame 14 and supported by the frame 14. The glass unit 15 is disposed in front of the game board 12 to protect the game board 12. As the game machine 10, an example of a pachinko machine is illustrated in fig. 1, but a slot machine may be used.

The front surface of the game board 12 has a game area 12A for playing a game, and the game area 12A can be seen from the outside through the glass unit 15. In the pachinko machine, a wall surface (outer wall surface) 12B that partitions the outside of the play area 12A is provided in the play area 12A. In the pachinko machine, the play area 12A is an area of a path through which the pachinko thrown in from the guide port 12C falls by gravity until it is discharged from the outlet 12D.

The glass unit 15 contains a light-emitting material that emits visible light having a wavelength of 380 to 780nm by excitation light. Therefore, when excitation light is irradiated from a light source 16 described later to the glass unit 15, visible light is emitted by irradiation of the excitation light.

As shown in fig. 2, in the present embodiment, a light source 16 for emitting excitation light is provided around the glass unit 15 in the front cover 13. The light source 16 is not particularly limited as long as it is a light source medium capable of emitting light of an excitation wavelength capable of exciting the light-emitting material, and a laser light source, an LED light source, a xenon lamp, or the like can be used, and an LED light source or an LD light source (semiconductor laser light source) is preferably used. If an LED light source, an LD light source, or the like is used, the space for disposing the light source 16 is reduced, and the increase in size of the game machine 10 due to the installation of the light source 16 can be prevented. The excitation light emitted from the light source 16 may be any excitation light that can be incident on the glass unit 15 and cause the glass unit 15 to emit visible light.

The maximum wavelength of the light emitted from the light source 16 is not particularly limited, but is preferably 430nm or less, more preferably 420nm or less, and still more preferably 410nm or less. Further, it is preferably 300nm or more, more preferably 350nm or more, and further preferably 365nm or more.

By setting the maximum wavelength of the light emitted from the light source 16 to be equal to or higher than the lower limit value and equal to or lower than the upper limit value, the glass unit 15 can emit visible light more efficiently by the excitation light from the light source 16.

The light-emitting material may emit visible light as described above, and preferably emits visible light having a maximum emission wavelength of 440nm or more, and can display blue, green, and red. Further, for example, if the visible light having a wavelength of 570nm or more is used, the visible light is yellow or red, and is suitable as a color for heightening the player's mood, indicating a hit or a hit.

The light source 16 provided around the glass unit 15 emits excitation light to the glass unit 15 from the outer peripheral surface 15X side of the glass unit 15. Here, a plurality of light sources 16 are provided, and as shown in fig. 2, the light sources are preferably provided so as to surround the glass unit 15.

The light source 16 may be attached to the outer peripheral surface 15X of the glass unit 15 or may be attached to the frame 14.

Fig. 3 is a schematic perspective view showing the glass unit 15 of the present embodiment in more detail. As shown in fig. 3, the glass unit 15 is a laminated glass including, for example, 2 transparent plates 15A and 15B and an interlayer film 15C provided therebetween, and the transparent plates 15A and 15B are bonded to each other through the interlayer film 15C. In the glass unit 15, the intermediate film 15C may be made of a resin film containing a light emitting material (light emitting layer), and 2 or more resin films may be provided, and at least 1 resin film is a resin film containing a light emitting material (light emitting layer). The 2 or more resin films may be laminated in a plurality of layers in the thickness direction.

However, the glass unit 15 is not limited to such a structure, and may have any structure as long as it has at least 1 light-emitting layer that emits light, as described in detail below.

Further, as shown in fig. 3, each light source 16 may be disposed such that its emission end 16A faces the outer peripheral surface 15X of the glass unit 15. In addition, in order to improve the light emission efficiency of the glass unit 15, the emission end 16A of the light source 16 is preferably disposed to face or contact the light emitting layer (the intermediate film 15C in fig. 3) of the glass unit 15.

The optical axis of the light source 16 may be parallel to the surface direction of the glass unit 15, or may be appropriately inclined with respect to the surface direction. Since the excitation light from the light source 16 is less likely to enter the inside by tilting the optical axis, it is easier to cause only the outer peripheral portion of the glass unit 15 to emit light.

In the case where the interlayer film 15C having a light-emitting layer is provided between the 2 transparent plates 15A and 15B, the light source 16 may be formed of, for example, an LED chip, and may be disposed between the transparent plates 15A and 15B in the vicinity of the outer peripheral surface 15X or the outer peripheral surface 15X. In this case, the light source 16 may be attached to the transparent plates 15A and 15B, or may be embedded in the resin film 15C. Further, a diffusion lens or the like may be provided at the emission end 16A of the light source 16, and the excitation light from the light source 16 may be diffused and incident on the glass unit 15.

The excitation light emitted from the light source 16 enters the glass unit 15 from the outer peripheral surface 15X side, and thereby the light quantity is attenuated and the light quantity enters the glass unit 15. Therefore, by adjusting the light amount to such an extent that the light amount does not enter the center of the glass unit 15, the outer periphery of the glass unit 15 can be caused to emit light without causing the center of the glass unit 15 to emit light. In the present embodiment, various representations can be made by causing the outer peripheral portion of the glass unit 15 to emit light.

Note that the term "not to emit light at the center" does not mean that light is not emitted at all strictly, and includes light emission only to the extent that it is not visually detectable.

In the present embodiment, for example, by emitting light from a part of the light source 16, as shown in fig. 4 a and B, a part of the region of the outer periphery of the glass unit 15 (hereinafter also referred to as "light-emitting region 15E") can be emitted. Further, for example, by causing all the light sources 16 to emit light, the outer peripheral portion can be caused to emit light over the entire circumference as shown in fig. 4 (C). The light-emitting region 12E may have various shapes, and may be, for example, a wavy pattern as shown in fig. 4, but the pattern is not particularly limited and may be any pattern.

Here, if the irradiation intensity of the light source 16 is adjusted, the range in which the excitation light from the light source 16 enters changes, and the size of the light emitting region 15E can be appropriately changed as shown in fig. 4(a) and (B). In addition, the appearance of the light-emitting region 12E (pattern) can be adjusted by adjusting the light-emitting time (i.e., the irradiation time of the light source 16). Further, the glass unit 15 emits light of various colors depending on the contained light emitting material.

Therefore, for example, it may be indicated that clouds or aurora exist on the outer periphery of the glass unit 15, or it may be indicated that the light source 16 emits light for a short time to appear as if a flash is generated.

As described above, according to embodiment 1, various representations can be made using the outer peripheral portion of the glass unit 15. In embodiment 1, various representations may be performed by adjusting the excitation light emitted from each light source 16 so as to be irradiated to the central portion of the glass unit 15, and causing the central portion of the glass unit 15 to emit light as well.

In embodiment 1, the light source 16 is disposed so as to surround the entire periphery of the glass unit 15, but is not necessarily disposed so as to surround the entire periphery. For example, as shown in fig. 4(a) and (B), when the glass unit 15 is used to show that only a part of the outer peripheral portion is made to emit light, the glass unit 15 may be provided so as to face only a part of the entire periphery thereof. In addition, in embodiment 1, the number of light sources 16 included in the game machine 10 may be only 1. Furthermore, the light source 16 may be movable, e.g. may be swingable. Specifically, the light source 16 may be oscillated about the optical axis. By swinging the light source 16, various representations can be made.

(embodiment 2)

Next, embodiment 2 of the present invention will be described with respect to the differences from embodiment 1. In the present embodiment, as shown in fig. 5, a light guide 20 is provided around the glass unit 15. The light guide 20 is provided in the front cover 13 (see fig. 1) and is disposed to extend along the outer peripheral surface 15X of the glass unit 15. And a light source 16 having an emission end 16A disposed opposite to the end 20A of the light guide 20, wherein excitation light from the light source 16 is incident on the end 20A, and the excitation light is incident on the glass unit 15 from the outer peripheral surface 15X via the light guide 20.

Here, the light guide 20 may be any light guide 20 as long as excitation light incident from the end portion 20A can be emitted from the side surface 20X of the light guide 20. Specifically, a side-emitting optical fiber may be used. Examples of the side-emitting optical fiber include an optical fiber in which a light scattering body or the like is dispersed in an optical fiber having a core and a cladding. Further, in the side surface 20X of the light guide 20, the portion not facing the glass unit 15 does not need to emit excitation light, and therefore, a film that absorbs or reflects the excitation light can be formed. Specifically, a coating film containing an ultraviolet absorber may be formed.

Light emitted from side surface 20X of light guide 20 enters glass unit 15 from the outer peripheral surface 15X side of glass unit 15. The excitation light incident inside the glass unit 15 is wavelength-converted by the light emitting material contained inside the glass unit 15, and is radiated from the glass unit 15 as visible light.

The light guide 20 is constituted by 1 piece, for example, and may be provided along a part of the outer peripheral surface 15X as shown in fig. 5, or may be provided along the entire periphery of the outer peripheral surface 15X. The number of light guides 20 is not limited, and may be 2 or more arranged along the outer peripheral surface 15X at different positions from each other in the circumferential direction of the glass unit 15, for example. In this case, the excitation light is preferably incident on each light guide from each light source.

According to the technical configuration of embodiment 2 described above, the outer peripheral portion of the glass unit 15 can be caused to emit light, as in embodiment 1.

(embodiment 3)

Next, embodiment 3 of the present invention will be explained. In embodiments 1 and 2, the excitation light from the light source 16 enters the glass unit 15 from the outer peripheral surface side, but in the present embodiment, enters from the game board side. Hereinafter, the present embodiment will be described with respect to the differences from embodiment 1.

In the present embodiment, as shown in fig. 6, the light source 16 is provided on the game board 12, and excitation light is irradiated from the game board 12 side to the glass unit 15. The position where the light source 16 is disposed is not particularly limited, and may be attached to the game board 12. Such as shown in fig. 6, may be provided in the play area 12A. The present invention may be provided on the outer wall surface 12B of the game area 12A of the game board 12. The light source 16 may be attached to various members such as a winning zone, a winning prize slot, a wind wheel, and other decorative members provided on the front surface of the game board 12. Further, the light source 16 may be provided in an area outside the game area 12A, for example, in the front face 12F of a wall portion constituting the outer wall surface 12B.

In the present embodiment, only 1 light source 16 may be provided, but a plurality of light sources are preferably provided. By providing a plurality of light sources 16, various representations can be made.

In addition, in the present embodiment, the light source 16 may be movable. If the light source 16 is movable, more various indications can be displayed by the light emission of the glass unit 15. Specifically, for example, a rail, a guide, or the like may be provided on the game board 12, and the light source 16 may be linearly or curvilinearly moved. In addition, the light source 16 may be configured to be capable of swinging. The light source 16 may swing around the optical axis of the light source 16, for example.

In the present embodiment, as in embodiment 1, various representations can be made by irradiating excitation light from the light source 16 to cause at least a partial region of the glass unit 15 to emit light.

Specifically, as shown in fig. 7(a), light emitting regions 15E having various shapes such as a sphere, a star, and a quadrangle are formed on the glass unit, and starry sky, fluorescent light, and the like can be obtained. At this time, the size of the light emitting region 15E can be changed by adjusting the irradiation intensity of the light source 16. The light emitting region 15E can be formed into a desired shape by, for example, adjusting the shape of the emission end of the light source 16 or providing a mask on the emission end of the light source 16.

In the present embodiment, the central portion of the glass unit may be caused to emit light as shown in fig. 7, or only the outer peripheral portion of the glass unit may be caused to emit light as shown in fig. 4. When the outer peripheral portion of the glass unit is caused to emit light, the light source 16 may be disposed at a position near the outer peripheral surface 15X of the game board 12.

Further, by moving the light source 16 for emitting excitation light, the light emitting region 15E can be moved as shown in fig. 7(B) and (C). If the light emitting region 15E moves, expression such as meteoric motion, flaming motion, and chopping motion (light indicating a trajectory of striking a chop with a knife or a trajectory of striking a fist) can be performed. In addition, by appropriately combining the light sources 16, various representations as shown in fig. 9 to 12 described later can be made.

As described above, in the present embodiment, as in the above embodiments, various representations can be made using a glass unit.

(embodiment 4)

Next, embodiment 4 will be described with respect to the differences from embodiment 3. In embodiment 3 described above, the light source is constituted by an LED light source, an LD light source, or another light source medium alone, but in the present embodiment, a light source unit is constituted by combining with a MEMS mirror or the like and used as a projection system capable of displaying various images. Specifically, for example, as shown in FIG. 8, a light source unit 30 having a MEMS (Micro Electro Mechanical Systems) mirror 31 in addition to the light source 16 for emitting excitation light can be used. The light source unit 30 is not particularly limited as long as it is located at a position where excitation light can be irradiated to the glass unit 15, and may be provided on the game board 12 or various members located on the game board 12 in the same manner as in embodiment 3 described above so that the excitation light irradiated from the light source 16 enters the glass unit 15 from the game board 12 side. The light source unit 30 is usually provided in the game machine 10 only in 1 number, but may be provided in 2 or more.

The MEMS mirror 31 can oscillate around the 2-axis, for example, and irradiates the glass unit 15 with light from the light source 16 while scanning the light. Here, the excitation light from the light source 16 is irradiated to the glass unit 15 via the MEMS mirror 31 which is drive-controlled, thereby being irradiated to the glass unit 15 in the form of scanning light. In the present embodiment, by controlling the driving of the MEMS mirror 31, the glass unit 15 can be caused to emit light so that a desired image is displayed in a desired region. Further, since the light source unit 30 using the MEMS mirror is generally small, the use of the MEMS mirror can prevent the game machine from being large-sized due to the light source unit 30.

As in the present embodiment, if the projection system is used, various representations can be easily performed as shown in fig. 9. Specifically, a reel that can change the pattern is displayed on the glass unit 15 as shown in fig. 9(a), or various characters, signs, icons, characters, and the like can be displayed as shown in fig. 9(B), (C), and (D). In the present embodiment, since the projection system is used, characters, signs, icons, characters, and the like can be freely changed. Therefore, as shown in fig. 9(D), event information and the like performed in the store may be displayed.

Further, as shown in fig. 9(E), a moving image showing a complicated motion of blood splash or bullet marks may be displayed, or as shown in fig. 9(F), various representations may be performed by emitting light in a certain area.

As shown in fig. 10, a screen 17 of a display device, which is usually constituted by a liquid crystal display or the like, is provided on the front surface of the game board 12 of the pachinko machine. The screen 17 displays a scroll, a video for other display, and the like. In the present embodiment, as shown in fig. 10, a rectangular region overlapping with the screen 17 of the display device may be used as the light emitting region 15E when viewed from the front. As shown in fig. 11, for example, a light-emitting region 15E may be provided to overlap a part of the screen 17 of the display device. At this time, for example, bullet marks, blood splashes, meteors, sparks, and light chopping can be expressed by the light-emitting region 15E. According to the representations shown in fig. 10 and 11, the influence displayed on the light-emitting region 15E of the glass unit 15 can be superimposed on the influence displayed on the screen 17 of the display device, thereby producing a three-dimensional effect.

The light emitting region 15E does not necessarily have to overlap the screen 17 of the display device, and may be formed in a frame shape surrounding the screen 17 of the display device as shown in fig. 12, for example.

As described above, in embodiment 4, by using the projection system, various representations can be made.

The light source unit in the present embodiment may be a unit other than the light source unit having the MEMS mirror 31, as long as it constitutes a projection system capable of displaying various images. As such a light source unit, a unit other than the light source unit having the MEMS mirror 31 may be used to irradiate scanning light. Since the light source unit for emitting scanning light is generally small, the glass unit can be made to emit light without increasing the size of the game machine, as in the case of the light source unit having the MEMS mirror.

Further, the light source unit may be a light source unit capable of irradiating the glass unit with the excitation light as a light beam. The light beams irradiate all light emitting portions of the glass unit at the same timing, and scanning deviation or the like does not occur as in the case of using scanning light.

Examples of the unit other than the light source unit having the MEMS mirror include a light source unit using a DMD (Digital micro mirror Device) system using DLP (Digital light Processing), an LCOS (Liquid crystal on silicon) system, and the like.

In the above description, the glass unit is explained on the premise that it emits monochromatic light by irradiation of specific excitation light, but the glass unit may emit light of a plurality of colors. In this case, the glass unit contains a plurality of luminescent materials whose maximum excitation wavelength and maximum luminescence wavelength are different from each other. The light source may be a light source that emits light corresponding to the excitation wavelength of each light-emitting material, and the wavelength of the excitation light to be irradiated may be changed according to the color of the emitted light. For example, a plurality of light sources that emit excitation lights different from each other may be prepared. Alternatively, a light source to which an optical filter capable of changing the transmission wavelength is attached may be used.

[ light emission control of glass Unit ]

Next, a specific example of the light emission control of the glass unit will be described in detail.

The light emission of the glass unit 15 may be controlled by any method, but is preferably controlled in linkage with the game motion of the game machine 10. For example, the light emission state of the glass unit 15 may be changed when any one of game actions selected from winning, hitting, standing, missing, occurrence of a probability fluctuation, a mode change due to a change in the probability fluctuation, an end of the probability fluctuation, and an end of a hit period is performed.

More specifically, when a game action desired by the player occurs, such as a prize winning, a hit, standing, or a probability variation, the glass unit 15 may be caused to emit light as shown in fig. 4,7, 9 to 12, or when light is emitted, the light emission intensity may be increased or the light emission region 15E may be enlarged. In this case, it is preferable that visible light having a maximum emission wavelength of 450nm or more is emitted, and blue, green, and red colors can be expressed. Further, for example, if the visible light having a wavelength of 570nm or more is used, the visible light is yellow or red, and is suitable as a color for heightening the player's emotion, indicating a hit or a near hit, so that the player's emotion when a desired game action is generated is further increased, and the entertainment is improved.

When a game action unintended by the player is ended, such as a miss, a probability variation, or a hit period, the light emitting action may be ended, the light emitting intensity may be reduced, or the light emitting region 15E may be decreased.

For example, when standing upright is detected, the light emitting area or the light emitting intensity may be set to be larger than the light emitting area or the light emitting intensity when winning is detected. Similarly, when a hit is detected, the light emitting area or light emitting intensity may be set to be larger than the light emitting area or light emitting intensity when standing upright or winning a prize is detected.

Since the player's feeling is likely to be heightened by increasing the light emitting area or the light emitting intensity, the player can be given a feeling of expectation with respect to hitting and standing, and the entertainment can be further improved.

As described above, when the glass unit 15 can emit visible light of different colors by emitting excitation light of different wavelengths, the color of light emitted from the glass unit 15 can be changed according to the game action.

For example, in a normal state, the glass unit 15 may emit visible light of green or blue, preferably visible light of blue. More specifically, the emission wavelength of visible light is preferably less than 570nm, more preferably 530nm or less, and still more preferably 450 to 520 nm. The visible light of green or blue calms the player's mood and makes the player enjoy the game comfortably in a normal state. In general, the normal state is a state in which no prize winning, hit, standing, or probability variation occurs.

On the other hand, when a game action desired by the player occurs, such as a prize winning, a hit, standing, or a probability change, the glass unit 15 preferably emits visible light of yellow or red, more preferably red, as described above. Specifically, the emission of visible light having a maximum emission wavelength of 570nm or more, more preferably 580 to 750nm, and still more preferably 590 to 690nm is preferable.

In addition, the winning in the pinball machine means that a pinball enters a winning slot provided in a game surface of a game board, and the pinball falls out or a lottery for a hit is obtained by winning. In this specification, the winning in the slot machine means that coins are inserted and a button or the like is appropriately pressed to start the rotation of the reel.

Hit in a pachinko machine means that various rights are obtained by winning or drawing, for example, by occurrence of a hit, opening of a predetermined winning gate such as a winning zone, etc. In the slot machine, the coin is dropped by matching the pattern of the reels.

The standing position indicates a drawing hit expected to be obtained, and for example, indicates a state in which the pattern of the reel can be hit by matching 1 more.

In addition, the miss indicates, for example, a lottery miss obtained by winning a prize in a pachinko machine. In a slot machine, the reels do not match despite the winning of a prize.

The probability variation indicates a state in which the probability of occurrence of a lottery hit is high, and occurs, for example, when a specific hit (a jackpot) is obtained among hits. On the other hand, the probability variation ends, for example, when a specific hit (a small or medium bet) is obtained among the hits, or when the number of balls to be hit after the occurrence of the probability variation exceeds a specific number. The pattern change is a change in an operation such as presentation performed in the game machine in accordance with a change in the probability fluctuation (for example, a change in the start and end of the probability fluctuation or a change in the hit probability).

The hit period means a period in which a hit occurs in the pachinko machine and a predetermined prize-winning slot such as a winning zone is opened.

Next, an example of a light emission control program of the glass unit of the present invention will be described with reference to fig. 13. Although an example of a control program for the game machine according to embodiment 4 will be described below, the control can be performed similarly in the game machines according to embodiments 1 to 3. In addition, a control unit such as a CPU is generally provided in the game machine, and the following program is executed by controlling the operation of the light source by the control unit.

As shown in fig. 13, the program first determines whether or not the prize slot is awarded a marble prize in S11, and if it is determined that the prize is awarded, the program proceeds to S12, and if the prize is not awarded, the program stands by in S11. At S12, light emission is performed to indicate winning. As light emission, for example, the light-emitting region 15E may be caused to emit light for a short time (for example, 1 second or less), or the light-emitting region 15E may be caused to emit light so as to surround the screen 17 as shown in fig. 12. Note that the light emission performed in this routine may be any light emission, and in the following description of this routine, a case where the light emission shown in fig. 12 is performed will be described.

Next, in S13, the result of the lottery drawing resulting from the winning is read, and whether or not the result of the lottery drawing stands upright is detected. Here, if it is detected that the vehicle is not standing, a miss is indicated in S20. The non-emission state of the glass unit 15 may be maintained for several seconds. When the light emission control corresponding to the failure is ended, the present routine returns to step S11. When a display failure is made in the glass unit 15, the display failure is also made in the screen 17 of the display device, and the glass unit 15 is linked with the display on the screen 17. Note that, as an indication of a miss on the screen 17, for example, a video image in which the reel is stopped in a state where the patterns do not match can be played.

On the other hand, if it is detected in S13 that the lottery result is upright, a lighting operation indicating upright is started in S14. As the operation of emitting light to show standing, any operation may be performed, and here, the operation of emitting light from the light emitting region 15E surrounding the screen 17 of the display device shown in fig. 12 is performed. In this case, either the emission intensity or the emission region may be larger than the emission performed in S12. The light emission in S14 may be longer than the light emission time in S12, for example, 10 seconds or more. The light emission may be performed continuously or intermittently. With such standing representation, the player's emotion is heightened, and the expectation for hits is improved.

In addition, in the case of standing upright, since the display device normally displays the screen 17 in accordance with standing upright, the light emission of the glass unit 15 is performed in conjunction with the display on the screen 17.

Next, in S15, it is detected whether the lottery result hits. If there is a hit, the representation corresponding to the hit is made in S16. The indication may be arbitrary, and for example, as shown in fig. 12, a light-emitting region 15E surrounding a screen 17 of the display device may be caused to emit light during a hit period. In this case, for example, either the light emission intensity or the light emission region may be larger than the light emission intensity or the light emission region of the light emission performed in S14. By such a hit indication, the player can feel the occurrence of the hit reliably, and the entertainment can be further improved. The light emission may be performed continuously or intermittently. When S16 ends, the process returns to S11. Further, if a hit occurs, the display device screen 17 normally displays a display corresponding to the hit, and therefore the light emission of the glass unit 15 is performed in conjunction with the display on the display device screen 17.

On the other hand, in S15, if a miss is detected, the process proceeds to S20, and in S20, the above-described miss may be indicated.

The above light emission control program is only an example, and any other light emission control may be performed. For example, the light emission state may be changed according to the type of hit or stand. More specifically, the light emission state may be changed depending on whether the hit is a medium or medium lottery. In addition, the light emission state may be changed depending on whether the normal standing position or the standing position with a higher occurrence probability of the jackpot than the other standing positions. In addition, the light emission state at the time of occurrence of the standing or hitting can be changed depending on whether or not the probability is changed.

Further, the light emission state of the glass unit may be changed when the probability variation occurs or ends, and the occurrence or end of the probability variation may be indicated by the light emission of the glass unit.

The light-emitting material is a material that radiates visible light by incidence of excitation light, and more specifically, a material that absorbs excitation light emitted from the light source and emits visible light having a longer wavelength than the excitation light.

Examples of the light-emitting material having a terephthalate structure include a compound having a structure represented by the following general formula (9) and a compound having a structure represented by the following general formula (10).

(resin film)

As described above, the glass cell is preferably provided with a resin film serving as a light-emitting layer. The glass unit preferably has a laminated glass structure in which an interlayer film is provided between 2 transparent plates, and the 2 transparent plates are bonded via the interlayer film.

In the laminated glass structure, the interlayer film is preferably formed of 1 resin film, which is a light-emitting layer. In addition, 2 or more resin films may be provided on the intermediate film, and at least 1 resin film among the plurality of resin films may serve as the light-emitting layer.

The resin film to be a light-emitting layer does not necessarily need to constitute an interlayer, and may be provided on the surface of any transparent plate opposite to the surface on the interlayer side, for example, in a laminated glass structure. In the case where the transparent plate provided in the glass unit is 1 sheet, it may be provided on either surface of the single-layer transparent plate.

In the case where a resin film as a light-emitting layer is provided on either one of the surface of the single-layer transparent plate or the surface opposite to the above-mentioned laminated glass structure, a sheet-like member having a light-emitting layer (resin film) may be bonded to the surface of the single-layer glass or the laminated glass structure with an adhesive, a bonding agent, or the like. In this way, the sheet-like member is bonded to the conventional glass unit by so-called post bonding, whereby the light-emitting layer can be provided on the glass unit.

The resin film to be a light-emitting layer contains a resin and a light-emitting material, and is usually a film in which a light-emitting material is dispersed in a resin. The light-emitting material is preferably dispersed throughout the entire light-emitting layer. Therefore, the glass unit emits visible light regardless of the position of the glass unit to which the excitation light is applied.

As the resin used in the resin film, a thermoplastic resin is preferable. By using a thermoplastic resin, the resin film easily functions as an adhesive layer, and when an interlayer film is formed, the resin film is easily adhered to a transparent plate or the like as described above.

When the resin film contains the light-emitting material, the content of the light-emitting material is preferably 0.001 parts by mass, more preferably 0.05 parts by mass or more, and still more preferably 0.1 parts by mass or more, per 100 parts by mass of the resin. By setting the content of the light-emitting material to be equal to or more than these lower limit values, the glass unit can sufficiently emit light. The content of the light-emitting material is preferably 10 parts by mass or less, more preferably 3 parts by mass or less, and still more preferably 1.5 parts by mass or less. By setting these upper limit values or less, the transparency of the glass unit can be easily ensured.

The thickness of the resin film is not particularly limited, and is, for example, 0.1 to 2mm, preferably 0.2 to 1 mm. If the thickness of the resin film is set to this range, sufficient light emission luminance is ensured without impairing the transparency of the glass cell.

The thickness of the interlayer film is not particularly limited, and is, for example, 0.1 to 3mm, preferably 0.2 to 2 mm.

As described above, as the resin used in the resin film, a thermoplastic resin is preferable. The thermoplastic resin used in the resin film is not particularly limited, and examples thereof include polyvinyl acetal resins, ethylene-vinyl acetate copolymer resins, ionomer resins, polyurethane resins, thermoplastic elastomers, and the like. By using these resins, the adhesion of the resin film to the transparent plate can be easily ensured, and the resin film is particularly suitable for the case where the intermediate film is formed of a resin film.

In the resin film, 1 kind of thermoplastic resin may be used alone, or 2 or more kinds may be used in combination. Among these, polyvinyl acetal resins are particularly preferable because they exhibit excellent adhesion to inorganic glass when the resin film contains a plasticizer.

In the case where the resin film contains a thermoplastic resin, the resin film may further contain a plasticizer. When the resin film contains a plasticizer, the resin film becomes soft, and as a result, the glass cell becomes soft. In addition, when the transparent plate, particularly the transparent plate is made of inorganic glass, adhesiveness with the transparent plate can be improved. In the case of using a polyvinyl acetal resin as the thermoplastic resin, it is particularly effective to contain a plasticizer in the layer.

Examples of the plasticizer include organic ester plasticizers such as monobasic organic acid esters and polybasic organic acid esters, and phosphoric acid plasticizers such as organic phosphoric acid plasticizers and organic phosphorous acid plasticizers. Among them, organic ester plasticizers are preferable, and triethylene glycol di-2-ethylhexanoate (3GO) is particularly preferable.

The content of the plasticizer is not particularly limited, and the lower limit is preferably 30 parts by mass and the upper limit is preferably 70 parts by mass with respect to 100 parts by mass of the thermoplastic resin. When the content of the plasticizer is 30 parts by mass or more, the glass unit is appropriately softened, and the workability and the like are improved. Further, if the content of the plasticizer is 70 parts by mass or less, the plasticizer can be prevented from separating from the resin film. A more preferable lower limit of the content of the plasticizer is 35 parts by mass, and a more preferable upper limit is 63 parts by mass.

When the resin film of the present invention contains a thermoplastic resin, the resin film is mainly composed of a thermoplastic resin or a thermoplastic resin and a plasticizer, and the total amount of the thermoplastic resin and the plasticizer is usually 70% by mass or more, preferably 80% by mass or more, and more preferably 90% by mass or more, based on the total amount of the resin film.

The resin film which does not serve as the light-emitting layer is the same as described above except that it does not contain a light-emitting material. The resin film may contain additives such as an antioxidant, an adhesion regulator, an ultraviolet absorber, an infrared absorber, and an antistatic agent, if necessary.

In the case of using a thermoplastic resin, for example, the resin film may be formed by kneading materials constituting the intermediate film, such as a thermoplastic resin, a light-emitting material, and a plasticizer, and then subjecting the obtained composition to extrusion molding, press molding, or the like.

(transparent plate)

The transparent plate is not particularly limited as long as it can be used for a glass unit, and inorganic glass or organic glass can be used. The inorganic glass is not particularly limited, and examples thereof include transparent glass, float glass, polished glass, template glass, mesh glass, wire glass, and green glass.

The organic glass is generally glass called plexiglass, and is not particularly limited, and includes transparent organic glass made of a resin such as polycarbonate, acrylic resin, acrylic copolymer resin, or polyester.

In the case where the glass unit has 2 or more transparent plates, the plurality of transparent plates may be made of the same kind of material as each other or may be made of different materials. For example, in the case of having 2 transparent plates, one may be inorganic glass and the other may be organic glass. In the case of having a plurality of transparent plates, it is preferable that the plurality of transparent plates be all of inorganic glass or all of organic glass.

The thickness of each transparent plate is not particularly limited, but is, for example, about 0.1 to 15mm, preferably 0.5 to 5 mm. In the case where the glass unit has a plurality of transparent plates, the thicknesses of the respective transparent plates may be the same as or different from each other.

As described above, in the glass unit, the transparent plate may become a light emitting layer that emits visible light. In the case where the transparent plate becomes a light emitting layer, the transparent plate itself contains a light emitting material. In this case, the light-emitting material may be dispersed in an inorganic material constituting the inorganic glass or an organic material (resin) constituting the organic glass of the transparent plate. Here, the light emitting material may be dispersed throughout the entire transparent plate. When the transparent plate itself contains a light-emitting material, the content of the light-emitting material is preferably 0.001 parts by mass or more, more preferably 0.05 parts by mass or more, and still more preferably 0.1 parts by mass or more per 100 parts by mass of the inorganic material constituting the inorganic glass or 100 parts by mass of the resin constituting the organic glass. By setting the content of the light-emitting material to be equal to or more than these lower limit values, the glass unit can sufficiently emit light. The content of the light-emitting material is preferably 10 parts by mass or less, more preferably 3 parts by mass or less, and still more preferably 1.5 parts by mass or less. By setting the content of the inorganic material to be equal to or less than these upper limit values, it is possible to prevent the transparency of the glass unit from being impaired by the light-emitting material.

In the case where the transparent plate contains a light-emitting material to serve as a light-emitting layer, the glass unit may have a laminated glass structure as described above, or the transparent plate may be formed of a single layer. In the case of the laminated glass structure, at least 1 transparent plate may be used as the light emitting layer.

The glass unit transmits visible light so that the game board can be visually recognized from the outside. The visible light transmittance of the glass unit is preferably 50% or more, more preferably 70% or more. By increasing the visible light transmittance, the player can easily observe the game board surface. The upper limit of the visible light transmittance is not particularly limited, and the higher the visible light transmittance, the better the visible light transmittance, but practically, the upper limit is preferably 99% or less, and more preferably 95% or less. Further, the visible light transmittance can be measured, for example, based on JISR3106 (1998).

In addition, as described above, the glass unit emits visible light by incidence of excitation light from the light source. The visible light is light with a wavelength of 380-780 nm. The glass unit may emit light of blue, green, red, yellow, or the like, or may emit white light or the like by mixing light of 2 or more colors. In the case of mixing 2 or more colors of light, for example, 2 or more light-emitting layers may be provided, and the colors may be mixed by irradiating different light to each layer, but 2 or more light-emitting materials may be contained in 1 light-emitting layer.

In addition, as described above, the light emitting layer may contain 2 or more light emitting materials whose maximum light emission wavelength and maximum excitation wavelength are different from each other. With this configuration, the glass unit is irradiated with excitation light corresponding to the excitation wavelength of each light-emitting material, whereby light emission of 2 colors or more can be performed. In this case, it is preferable that 2 or more light-emitting layers be provided, and the maximum light-emitting wavelength and the maximum excitation wavelength of the light-emitting material contained in each light-emitting layer are different from those of the light-emitting materials contained in the other light-emitting layers. For the light emission of 2 colors or more, for example, a europium complex and a terbium complex having a ligand containing a halogen atom can be used as the light emitting material.
