Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine, and more particularly, at least a part of the ball entering device is constructed by using a cushioning member, so that the ball entering device is damaged or played by the impact of the game ball. The present invention relates to a ball-and-ball game machine capable of preventing chattering due to rebound of a ball.

2. Description of the Related Art In some ball game machines, for example, a special random number on the screen is changed by the value of a random number for determining whether or not a game ball has won or passed through a special symbol operation opening. By displaying the symbols in a certain pattern in a confirmed manner, the game content is in a state that is advantageous to the player, the so-called "big hit" is called, and the special winning opening is opened for a predetermined time. There is a model called "Fever machine" that pays out a large number of prize balls to the player corresponding to the number.
In addition, by the value of the winning / disapproval determination random number that is selected due to the timing at which the game ball wins or passes through the symbol working opening, the symbols that are changing on the screen are confirmed and displayed in line with the specific symbols. When the right acquisition winning opening is opened and the game ball wins a specific area in the right acquisition winning opening, it becomes a right acquisition state, and by hitting the right and putting the game ball into the rotating body, it becomes a so-called "big hit" state, There is also a model called a "proprietary property" in which the prize holes are opened for a predetermined time and the prize balls are obtained in accordance with the number of game balls that have won the big prize hole. Usually, these ball game machines, special symbol working port,
Provide a game ball that has entered or passed through a ball entry device (including a prize winning device or passing device) such as a symbol working opening, a rights acquisition winning opening, a big winning opening or a rotating body, etc. A big hit is generated or a prize ball is paid out by detecting with a detection device such as a switch or a sensor.

[0003]

However, since the game balls frequently collide with the ball-entering device, the damage due to the impact due to the collision of the game balls may occur. Also, when a detection device is provided in the ball passage such as in the ball entrance device, the game ball that entered the ball entrance device is detected by this detection device, but the game ball bounces in the ball entrance device etc. As a result, chattering may occur in which the game ball once detected is detected again by the detection device. Conventionally,
To prevent this chattering, as part of measures against noise, it is considered that the detection switch has certainly turned on when the detection switch on state continues for a predetermined time, and conversely, if it does not continue for the predetermined time, it is determined that it is accidentally turned on due to noise. Patent applications have been filed and those that use a waveform shaping circuit to remove distortion. However, these methods only deal with noise, and there is a problem that chattering due to rebound of the game ball cannot be dealt with. Also,
In Japanese Patent Laid-Open No. 8-155080, a pressure sensor, which is a detection device for detecting a game ball by using the momentum flowing down a ball passage, is installed in the ball-entering device, and in order to prevent the pressure sensor from being damaged, a game is played. An invention is disclosed in which a cushioning member is provided at a location where a ball directly collides. However, this is only that the cushioning member is provided in the ball entrance device for protecting the pressure sensor, and there is no relation between the cushioning member and the prevention of the chattering described above.
Therefore, in order to preferably solve the above two problems, damage to the ball-entering device due to the impact caused by the collision of the game balls is prevented, and a detecting device is provided in the ball passage such as in the ball-entering device. Provide a ball-and-ball game machine that can be expected to prevent chattering.

[0004]

In order to solve the above-mentioned problems, the invention according to claim 1 is to enter a ball-entering device into which a game ball shot on a game board surface can enter, and to enter the ball-entering device. In a ball game machine equipped with a ball passage through which the game ball passes and a detecting device for detecting the game ball entering the ball entering device in the middle of the ball passage, the ball hitting the downstream side of the detecting device. A ball-and-ball game machine characterized in that at least a part of the ball passage is formed of a cushioning member. Thereby, in the ball passage, since the impact due to the collision of the game ball is cushioned by the cushioning member, the member forming the ball passage is preferably prevented from being damaged, and the bounce of the game ball in the ball passage is preferably suppressed.
It is possible to smoothly flow down the game ball. Furthermore, in addition to the above-mentioned effects that are normally expected by using a cushioning member for preventing damage, when the game ball collides with the ball passage downstream of the detection device, the game ball that has passed through the detection device has already been detected. In order to prevent rebound to the area that has passed (direction of the detection device) and prevent it from approaching the detection device again,
It is possible to prevent chattering in which the game ball once detected is detected again, and improve the reliability of the gaming machine. Also, from the viewpoint of manufacturing, compared to the case where the rebound of the game ball is suppressed due to the structure inside the ball entrance device, it is better to use a cushioning member for the design inside the ball entrance device (for example, the angle of inclination or bend of the ball passage). Design etc.) is easy.

"Entering a ball" means entering a game ball into a ball entering device, and broadly including winning or passing. Therefore, the "ball-entering device" may be any device that can enter the game ball regardless of the presence or absence of a prize ball and the status of the game ball after entering the ball. For example, a prize winning device such as an ordinary electric accessory or a special winning opening,
Alternatively, a passage device such as a symbol working port is also included here. The "ball passage" is the area where the game balls pass in the ball-entering device, the area where the game balls pass when guiding the entered game balls to the back of the game board, and the number of prize balls is the same. In order to detect the game balls from a plurality of winning holes with the same detection device, the game balls are also included in a region where the game balls pass when the game balls are collected and guided on the back surface of the game board. As one mode of this ball passage, there is a structure that changes the course of the game ball on the way. For example, when the game ball flowing down is changed to the horizontal direction. The "detection device" is a device for detecting a game ball that has entered the ball entering device, a ball passage in the ball entering device, a ball passage through which the game ball passes when being guided to the back of the game board. Alternatively, it is preferably installed in a ball passageway or the like on the back surface of the game board. Therefore, the ball entrance device includes both the device with and without the detection device. In a ball-entry device that does not have a detection device, the entered game ball is detected by the detection device installed in the ball passage when it is guided to the back of the game board or when it passes through the back of the game board. Will be configured. For example, the detection device is preferably a switch or a sensor, and the detection method may be any of an optical type and a contact type. “At least a part” specifically means that any part of the ball passage, a plurality of locations, or the entire ball passage is formed of a cushioning member. Here, it is particularly preferable that at least a part of the region where the game balls on the downstream side of the detection device collide with each other is configured with a cushioning member. As the "cushioning member", an elastic body or a shock absorbing material having a small rebound is used. Specifically, a low resilience thermoplastic elastomer or viscoelastic rubber is preferred. The "configuration" may be any shape as long as a cushioning member is provided in the ball passage, or a cushioning member may be simply attached to a part of the ball passage, or a part of the ball passage may be formed by the cushioning member. It can be one.

The invention according to claim 2 is characterized in that a deceleration portion for decelerating the speed of the game ball entering the ball entering device is provided, and at least a part of the deceleration portion is constituted by a cushioning member. It is the ball game machine according to item 1. As a result, the impact applied from the outside to the ball entrance device can be softened, and in particular, the momentum of the game ball can be softened before entering the ball entrance device, resulting in a game in the ball entrance device. The impact caused by a ball collision can be mitigated. Therefore, it is possible to preferably prevent damage to the ball entrance device, and it is possible to preferably prevent bouncing of the game ball in the ball entrance device. For this reason, it is possible to eliminate the need for a game nail conventionally provided directly above the ball entrance device to prevent damage to the ball entrance device from the impact of a game ball collision.

The "deceleration portion" may have any shape, and may be a gate shape, a pin shape, a plate shape or the like as long as it slows down the speed of the game ball falling on the game board surface. It is preferably provided just above the entrance of the device. For example, the gate shape is preferably a ring or the like through which a game ball can pass. Further, the pin shape is preferably constituted by a plurality of rod-shaped members (pins) extending vertically or at a predetermined angle on the game board. In addition, when the variable wing capable of enlarging or reducing the entrance of the ball entrance device is provided, the decelerating portion can be formed by forming a portion of the variable wing with which the game ball collides with a buffer member. Specifically, the speed of the game ball can be decelerated from the side when expanding (opening) and from the top when contracting (closing). When both the gate-shaped speed reducer and the variable blade are provided, the gate-shaped speed reducer is preferably provided at a position higher than the upper limit of the variable blade. Further, the portion constituted by the buffer member may be a part of the speed reducing portion or the entire speed reducing portion. Here, it is preferable to configure at least a part of the region where the game balls of the deceleration portion frequently collide with a buffer member.

The invention according to claim 3 is the ball-and-ball game machine according to claim 1 or 2, characterized in that a low-repulsion thermoplastic elastomer or viscoelastic rubber is used as the buffer member. "Low resilience" means that there is little or little repulsion even when a game ball collides. "Thermoplastic elastomer" is an abbreviation TP
E (Thermo Plastics Elastom
er), which is a thermoplastic having rubber elasticity and plays an intermediate role between plastic and rubber. Generally, an elastomer is a polymer substance that exhibits rubber elasticity at room temperature, and has a structure in which molecular motion is suppressed and rubber elasticity is lost at low temperatures. In a narrow sense, the elastomer is often referred to as the thermoplastic elastomer, but in a broad sense, it includes vulcanized rubber, thermoplastic elastomer, elastic fiber, elastic foam and the like. The base of the thermoplastic elastomer is a plastic type, and there are six types such as styrene type, vinyl chloride type, olefin type, polyester type, polyamide type and urethane type. The rubber component to be mixed is up to about 30%, and is mainly a copolymer of styrene and butadiene (SBR), a copolymer of acrylonitrile-butadiene (NBR), a copolymer of ethylene, propylene and diene (EPDM). Etc. are used. Unlike vulcanized rubber and the like, the thermoplastic elastomer can reuse the runner and the like after molding, and has high recyclability. Further, since it is thermoplastic, it softens at high temperatures and can be molded in the same manner as ordinary thermoplastic resins. The molding method is a plastic method, and injection molding is the mainstream, but extrusion molding and blow molding are also possible. The "viscoelastic rubber" is preferably a low-repulsion rubber (buffer rubber) capable of absorbing energy with almost no repulsion even when subjected to an external force. Here, most of the shock and vibration can be converted into heat and eliminated. As described above, both the thermoplastic elastomer and the viscoelastic rubber have excellent shock absorbing properties and have a small rebound, and thus are suitable as a cushioning member. Further, since injection molding or the like is possible, the component itself forming the ball entrance device can also be molded from a thermoplastic elastomer or viscoelastic rubber. In addition, used thermoplastic elastomers or viscoelastic rubbers contained in discarded game machines and other various wastes can be collected and remolded, making it easy to recycle as many times as possible. Therefore, it is possible to reduce costs and contribute to global environmental protection.

Here, the ordinary electric accessory 40 will be described with reference to FIGS. FIG. 4 is a perspective view of the ordinary electric accessory 40, and FIG. 5 is an exploded perspective view showing the internal structure of the ordinary electric accessory 40. The ordinary electric accessory 40 includes a main body 41, a front cover 43 attached to the front surface of the main body 41 via blades 42a and 42b, reinforcing members 44a and 44b attached to the side surfaces of the main body 41 by connecting rods 44, inside the main body.

As shown in the sectional view of FIG. 7A or FIG. 7B, the front cover 43 and the main body 41 form a spherical passage 40a.
The inside of the ball passage 40a is provided with an inclined surface by the back surface of the front cover 43, and changes the movement direction of the game ball that has dropped and entered the ball from the vertical direction to the horizontal direction. A detection device 45 is installed in the ball passage 40a, and the detection device 45 is
It is provided with a ring-shaped detection sensor 45a through which a falling game ball can pass. It is preferable that the game ball that has entered the ordinary electric accessory 40 always passes through the detection sensor 45a.

In the present embodiment, the cushioning member 49 is formed at a portion of the ordinary electric accessory 40 at which the game balls particularly frequently collide. As a result, the normal electric accessory 40 is extremely unlikely to be damaged by a collision or an impact of a game ball entering the ball. Specifically, the inclined surface on the back surface of the front cover 43 is formed by the cushioning member 49 (FIG. 7A).
reference). The buffer member 49 is appropriately formed into a shape that matches the shape of the inclined surface. Here, the cushioning member 49 is configured to be attached to the front cover 43, and it is preferable that the cushioning member 49 has a size that does not hinder the smooth flow down of the game ball in the ball passage 40a. As another specific example, the front cover 143 itself may be formed by the cushioning member 149 (FIG. 7).
(See (b)). At this time, the entire front cover 143 may be molded by the cushioning member 149 or a part thereof. The exterior of the front cover 143 may be configured by the cushioning member 149. Since the other components are almost the same as those of the above-described specific example, the description will be cited as each in the 100s. In any case, the place where the cushioning member 49 is provided may be at least a part of the ordinary electric accessory 40, or the ordinary electric accessory 40 may be entirely configured by the cushioning member 49. Further, for example, the cushioning member 4 is provided at a portion where the game balls of the blades 42a and 42b frequently collide or the entire blades 42a and 42b.
9 may be used (not shown). In this case, it is possible to reduce the speed of the game ball from the side when opening (enlarging) and from the top when closing (reducing).

The cushioning member 49 used here is preferably made of a material having excellent shock absorption and small rebound. For example, a low resilience thermoplastic elastomer or viscoelastic rubber (hereinafter referred to as a buffer rubber) is preferable.

The thermoplastic elastomer is a thermoplastic having rubber elasticity and plays an intermediate role between plastic and rubber. The base of the thermoplastic elastomer is a plastic type, and the rubber component mixed is preferably up to about 30%. The buffer member 49 used here is a polymer alloy type material composed of a plurality of polymers including an ester-based polymer and a halogen-based polymer, and has a property extremely close to rubber and is excellent in energy absorption. Is preferred. The impact resilience is preferably less than 10%, particularly preferably less than 3%. Further, a low hardness material (for example, durometer A hardness 13 to 70, particularly preferably durometer A hardness 40)
It is preferably about 60 to about 60), and the one having low environmental dependence such as humidity and the like, and particularly excellent in impact absorption is preferable. Furthermore, it is more preferable if it is excellent in vibration absorption, flexibility, recovery characteristics, low migration, abrasion resistance, oil resistance, weather resistance, ozone resistance and the like.

The thermoplastic elastomer used in this embodiment is molded by extrusion molding or injection molding. Therefore, it is possible to form the front cover 43 into an appropriate shape such as the shape of the front cover 43 or the shape of various parts. At the time of molding, pre-drying can prevent bubbles and the like, and the molding surface can be finished cleanly. In the case of extrusion molding, it is preferable to use a general soft vinyl chloride type screw having an L / D of 22 or more and a compression ratio of 2 to 4 as a molding machine. In addition, the die needs to be designed so that the resin does not stay. In the case of injection molding, it is preferable to use a molding machine that has a proven record with soft PVC resins. It should be noted that the thermoplastic elastomer may be thermally decomposed if left at a high temperature for a long time, so that care must be taken during molding. In addition, it is necessary to pay close attention to the residence time in the cylinder.

The shock-absorbing rubber is a unique rubber that can absorb energy with almost no repulsion even when subjected to an external force, and has the same physical properties and durability as ordinary rubber. In particular, in the normal temperature range (5 ° C to 35 ° C), the loss coefficient is larger than that of general rubber (for example, the maximum value is 1.3 tan δ or more, preferably 2.
1 tan δ or more), and has excellent shock absorption. The impact resilience is preferably less than 10% (particularly preferably less than 3%). The hardness is preferably about Durometer A hardness 32 to 57. Also, like thermoplastic elastomers, it can be extruded or injection molded, so it has excellent processability.
Can be molded into a wide range of shapes. The sponge shape can also reduce the weight. Strong adhesion to metal is also possible. It is also easy to recycle.

At least a part of the cushioning member 4 as described above.
An ordinary electric accessory 40 composed of 9 is usually a blade 4
2a, 42b is in a closed state (see FIG. 6 (a)), and when the normal symbol display device 37 displays a predetermined ordinary symbol (for example, "7"), the blades 42a, 42b have a prescribed time or a prescribed number of times. It is opened, and the probability of entering a game ball is improved (see FIG. 6B). In this embodiment, the normal symbol displayed on the normal symbol display device 37 (for example, "0" to "9") is caused by the game ball entering either of the normal symbol operation gates 38 and 39. However, other conditions may be set. Further, the ordinary electric accessory 40 may be opened / closed according to the display form displayed by the ordinary symbol display device 37, or may be opened / closed periodically depending on the number of jackpots or the elapsed time. In addition, it is preferable that the ordinary electric accessory 40 can enter the game ball even in the closed state.

When a game ball enters the ordinary electric accessory 40,
The game ball is detected when passing through the detection sensor 45a of the detection device 45, and the random number is extracted according to the timing,
The win / fail is determined by whether or not the win / fail random number matches a predetermined win / fail judgment value. According to the result of the hit / miss judgment, the special symbol starts changing on the LCD 32a. If it is a big hit, the complete confirmation display is performed with a predetermined special symbol (for example, the same three-digit symbol such as "555" and "777"), and the special winning opening 50 is opened for a predetermined time or a predetermined number of times. If it is not a big hit, it will be confirmed and displayed with a deviating pattern. At this time, if there is a hold in the LED 32b for special symbol hold storage, the process moves to the next change, and LE for special symbol hold storage
If there is no hold in D32b, it returns to the normal game state. In addition, the pachinko machine 10 of the present embodiment is configured as a probability varying machine, and when it is confirmed and displayed with a specific special symbol,
This is a structure that improves the jackpot probability. For example, the number of hit / miss judgment values, which is one at the time of normal probability, becomes 5 at the time of high probability, and the jackpot occurrence probability, which is 1/250 at the time of normal probability, becomes 1/50 (= 5/250) at the time of high probability. Details are omitted.

In this way, since the detection sensor 45a detects the game ball that has entered the ordinary electric accessory 40 to execute the hit determination, the game ball bounced in the ball passage 40a again detects the detection sensor 45a. When passing, one game ball may be detected a plurality of times (for example, twice), which may cause an inconvenience of preventing a fair game. in this case,
In particular, by configuring the ball passage 40a on the downstream side of the detection sensor 45a with the cushioning member 49, it is possible to suitably prevent rebound of the game ball that has entered the ball passage 40a and prevent damage to the ordinary electric accessory 40. Not only that, but also chattering can be suitably prevented.

As another example, an ordinary electric accessory 240 of another embodiment will be described with reference to FIGS.
FIG. 8 is a perspective view of the ordinary electric accessory 240, and FIG. 9 is an exploded perspective view showing the internal structure of the ordinary electric accessory 240. Here, a gate 241 a including a cushioning member 249 and the like is installed in the main body 241 just above the entrance of the ordinary electric accessory 240. All the gates 241a are buffer members 249.
May be configured, or a part thereof may be configured by the cushioning member 249. By the gate 241a,
Since the impact due to the collision of the game balls is softened, it is possible to preferably prevent the damage of each component forming the ordinary electric accessory 240. In addition, since the game ball collides with or comes into contact with the gate 241a, the momentum is relieved before entering the ball passage 240a in the electric powered accessory 240, so that rebound in the ball passage 240a is also preferably prevented. As a result, chattering can be appropriately prevented. As described above, the cushioning member 24 is provided in the vicinity of the ordinary electric accessory 240 in addition to the configuration of the ordinary electric accessory 240 itself.
It is also preferable to provide another component (for example, the gate 241a) configured by 9 or the like. Also here, similarly, the blade 2
The portions of the game balls 42a and 242b that frequently collide with each other or the entire blades 242a and 242b may be configured by the cushioning member 249 (not shown). As in this embodiment, the gate 2
When both 41a and blades 242a and 242b are provided, the gate 241a is preferably provided at a position higher than the upper limit (for example, when closed) of the blades 242a and 242b. Since the other configurations are substantially the same as those of the above-described embodiment, the description will be referred to as the 200s.

Next, the special winning opening 50 will be described with reference to FIGS. FIG. 10 is a perspective view of the special winning opening 50, and FIG. 11 is an exploded perspective view showing the internal structure of the special winning opening 50. The special winning opening 50 includes a front cover 53 having an opening door 52, a guide plate 51, an internal distribution member 54, and a back plate 5.

The detection device 58 provided with 8a, the detection device 59 provided with a ring-shaped detection sensor 59a through which the game ball can pass is installed in the specific area 54b. It is preferable that the game ball that has won the special winning opening 50 always passes through the detection sensor 58a or the detection sensor 59a.

The motor 56 opens and closes the opening door 52 by moving the actuator 56a as shown by the arrow in the figure. The motor 57 moves the guide plate 51 by moving the actuator 57a as shown by an arrow in the figure. It is preferable that the movable mode of the guide plate 51 be configured to tilt left and right by changing the angle about the central axis 51a. It is preferable that the guide plate 51 be periodically moved with a constant rhythm, but it is preferable that the guide plate 51 be moved under a predetermined condition (for example, the LCD 32a).
It may be moved according to the type of special symbol fixedly displayed in ().

The special winning opening 50 has a structure in which the opening door 52 is used as a receiving opening when it is opened, and the back surface 52a of the opening door 52 is a portion where the game ball hits most frequently when opening. In the present embodiment, the back surface 52a of the opening door 52 is configured by the cushioning member 60 such as the above-mentioned thermoplastic elastomer or cushioning rubber. The location formed by the cushioning member 60 is not limited to the back surface 52a of the opening door 52 illustrated in the drawing, but may be at least some part of the special winning opening 50. For example, the big prize hole 5
It is also preferable to configure the ball passage 50a inside 0 where the game balls collide with each other with a high frequency by the cushioning member 60.
Further, at least a part of the guide plate 51 may be configured by the cushioning member 60. As a result, the possibility that the special winning opening 50 will be damaged due to a collision or an impact of the game ball entering the ball is extremely low.

As described above, the special winning opening 50 is the LCD.
It is a configuration in which the symbols that are changing in 32a are aligned and confirmed and displayed in a predetermined special symbol, and the jackpot state is released. When the game ball wins the big winning opening 50 by bouncing to the open door 52, the guide plate 51 causes the count area 54a.
Alternatively, it is distributed to the specific area 54b. Counting area 54
The game ball that has entered a is a detection sensor 58a of the detection device 58.
Is detected at the time of passing, and a predetermined number of game balls corresponding to the number of game balls detected by the detection sensor 58a are paid out as prize balls (for example, 15 prize balls per game ball).
Further, the game ball that has entered the specific area 54b is a detection device 59.
The game ball is detected when passing through the detection sensor 59a, and the memory of the game ball causes the special winning opening 50 to be continuously opened.

Generally, the jackpot state is continued for a predetermined time or a predetermined number of times, but in the pachinko machine 10 of the present embodiment, it is 1
When 0 game balls enter the count area 54a and are detected by the detection sensor 58a, or when the opening time of the special winning opening 50 has passed 30 seconds, one round ends. During that time, the game ball enters the specific area 54b and is detected by the detection sensor 59a.
0 is released again and moves to the next round. Since this is continued up to 16 rounds, a maximum of 2400 prize balls can be paid out per jackpot. The round end condition and the number of rounds are not limited to these.

In the special winning opening 50, the guide plate 51 is tilted so that the count area 54a or the specific area 54b is formed.
It is a configuration that changes the winning rate to. As shown in the front view of FIG. 12A, when the guide plate 51 is not operated, it is sorted into the count area 54a or the specific area 54b depending on the momentum of the game ball or the winning angle into the special winning opening 50. The game ball that has entered the count area 54a is detected by the detection sensor 58a as shown in the cross-sectional view of FIG. The game ball that has entered the specific area 54b is detected by the detection sensor 59a as shown in the sectional view of FIG. Further, as shown in the front view of FIG. 12B, when the guide plate 51 is in operation, in addition to the momentum of the game ball or the winning angle into the special winning opening 50, the tilting of the guide plate 51 causes the count region 54a or It is distributed to the specific area 54b. The game ball that has entered the count area 54a is detected by the detection sensor 58a as shown in the sectional view of FIG.
The game ball that has entered the specific area 54b is detected by the detection sensor 59a as shown in the sectional view of FIG.
Here, in order to make the guide plate 51 inside the special winning opening 50 visible, the opening door 52 is not shown in FIGS. 12A and 12B for convenience.

In this way, the game balls that have won the special winning opening 50 are detected by the detection sensors 58a and 59a, and the prize balls are paid out, and the control related thereto is executed. Therefore, when the game ball bounced in the ball passage 50a passes through the detection sensors 58a and 59a again, there may occur inconveniences such as paying out more prize balls than necessary, and chattering may occur here as well. is there. However,
In the pachinko machine 10 according to the present embodiment, since the back surface 52a of the opening door 52 is composed of the cushioning member 60, the momentum of the game ball winning the big winning opening 50 can be weakened in advance, and the inside of the big winning opening 50 can be achieved. It is possible to preferably prevent the bouncing of the game ball in the game. Furthermore, the ball passage 50a inside the special winning opening 50
It is even more effective if a part of the above is constituted by the cushioning member 60. Thereby, not only the big winning opening 50 can be prevented from being damaged, but also chattering can be suitably prevented.

Further, the constitution using the above-mentioned thermoplastic elastomer or cushioning rubber can be applied to other ball-entering devices. For example, the winning holes 34, 35 and the normal symbol actuating gates 38, 39 are also a kind of the same ball-entering device as the normal electric auditors 40 and the special winning hole 50, and it is preferable to use a cushioning member 49. It does not matter even if the winning holes 34 and 35 are not provided with a sensor. Further, even if the cushioning member 49 is used for the ball entrance device such as the outlet 36, it is possible to prevent damage and the like, which is effective.

The present invention is not limited to the above-described embodiments, and modifications and the like can be added without departing from the technical idea of the present invention. Items and the like are also included in the technical scope of the present invention. For example, in the present embodiment, the special winning opening 50 has a configuration in which the opening door 52 is used as a receiving opening when it is opened, but the present invention is not limited to this. Further, the material of the cushioning member 49 used in the above embodiment is not limited to the thermoplastic elastomer, the cushioning rubber or the like, and if a more preferable material is developed, it can be used.

Further, for example, in addition to the model generally called "fever machine" described in the present embodiment, depending on the value of the random number for determining whether or not the game ball is won or passed through the symbol working opening, the random number is selected. , By changing the symbols on the screen to be confirmed and displayed in a specific pattern, the right acquisition winning opening is opened, and when the game ball wins the specific area within the right acquisition winning opening, it becomes the right acquisition state and right-handed By entering the game ball into the rotating body, it becomes a so-called "big hit" state, and the special prize hole may be opened for a predetermined time and the prize ball may be paid out to the player. . In this case, it is preferable to provide a buffer member on the symbol operation opening, the right acquisition winning opening, the rotating body or the special winning opening.
In addition, because the game ball enters the specific operation port, the electric accessory equipped with the blade member opens the blade portion to make the game state advantageous to the player, and the ball is provided inside the electric accessory. It may be a model called "Hikoki", which is commonly called "big hit" when it passes through the area. In this case, it is preferable to provide a cushioning member inside or outside the electric accessory, in a specific region, or in a wing member. Further, a model in which the above models are appropriately combined may be used.

According to the invention described in claims 1 to 3, at least a part of the ball entrance device is constructed by using a buffer member such as a low resilience thermoplastic elastomer or viscoelastic rubber. The impact due to the collision can be softened, and damage to the ball entrance device can be suitably prevented. Further, since the bouncing of the game ball is appropriately suppressed, it is possible to smoothly flow down the game ball in the ball entrance device. Furthermore, when the detection device is installed inside the winning device, the bouncing of the game ball is appropriately suppressed, so that a synergistic effect that even chattering can be prevented can be expected.
