Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a ball game machine, and more particularly to countermeasures against static electricity charged on a game ball.
[0002]
[Prior art]
A ball game machine is a gaming machine that fires a game ball on the surface of a game board by a player's operation and pays out a game ball as a prize ball in response to the return of the game ball. Pachinko machines that pay out prize balls when they enter, and arrange ball machines that pay out prize balls according to the combination of entrances into which game balls have entered are widely used. In these pachinko gaming machines and arrange ball machines, so-called pachinko balls made of iron having a diameter of about 11 mm are used as game balls.
[0003]
In addition to a device that controls the processing of game balls that have entered the prize opening, etc. and the execution of prize balls, the ball game machine also displays various effects to make the progress of the game more interesting. And a device that controls sound output. These devices are configured by electronic control devices configured by a microcomputer or the like today. In the ball game amusement hall, a large number of game machine installation islands lined up with a large number of such ball game machines are laid out in a bowl shape, and many players can be accepted.
[0004]
By the way, the above-mentioned game balls used in pachinko machines and arrange ball machines are returned to the game hall side from the player in exchange for prizes after being played, or collected as out balls, and then rented balls and prize balls again. And circulates in the amusement hall. In the middle of this circulation, the game ball is polished by a polishing device installed in common on the game ball installation island behind the game machine before being used in the game machine, so that rust and dirt are removed. In addition, the game progress and the payout of the prize ball are not hindered, and the player can enjoy the game comfortably with the glossy game ball.
[0005]
In the process in which the game balls are supplied to the game machine again, between the game balls and the abrasive of the polishing apparatus, between the game ball passages through which the game balls circulate, and between the game balls Friction occurs, and static electricity is charged on the surface of the game ball. If the static electricity is discharged when the game ball passes through the gaming machine, there is a possibility that the electronic control device malfunctions or breaks down due to noise generated thereby.
[0006]
As a countermeasure against noise due to static electricity, Japanese Patent Publication No. 5-56993 discloses a game ball passage in a gaming machine through which a gaming machine circulates made of a conductive synthetic resin containing a conductive component and grounded. . In this technique, carbon particles are used as the conductive component.
[0007]
[Problems to be solved by the invention]
By the way, in order to obtain a sufficient static elimination effect, it is sufficient to increase the content of the conductive component. However, if the content is increased, the game ball that has been polished and regained its gloss will pass through the game ball passage of the gaming machine. In the middle of flowing down, there is a possibility that the game ball itself will be soiled by the conductive component rubbed by the wear of the passage surface, and eventually the player or the game machine itself may be soiled.
[0008]
A static elimination synthetic resin that contains carbon-based ultrafine fibers as a conductive component in the passage member and dissipates static electricity in the air by generating corona discharge between the tip of the carbon-based ultrafine fibers and the surface of the game ball. The one used is also proposed (Japanese Patent Laid-Open No. 5-305177). According to this technique, there is almost no problem of adhesion of dirt by making carbon into an extremely fine fiber shape, but it is expensive which requires labor for manufacturing. As a result of using ultrafine fibers, the cost is significantly increased as compared with those using conductive fine particles such as carbon particles as the conductive component, which is not always practical.
[0009]
In addition, it is conceivable to use a material having high hardness and good scratch resistance for the passage member, and to suppress the passage surface from being worn by the game ball, but a material having good scratch resistance, such as polycarbonate, is expensive. Eventually, costs will rise.
[0010]
Accordingly, the present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a bullet ball game machine in which a conductive component is hardly attached to a game ball and the like, and a sufficient static electricity removing effect can be obtained. To do.
[0011]
[Means for Solving the Problems]
  In the first aspect of the present invention, an iron game ball is launched on the surface of the game board, and a game ball as a prize ball is caused to flow down a game ball passage provided behind the game board by the return of the fired game ball. At least, pay out from the supply port that opens below the game boardConfiguration,
  As a passage member constituting the game ball passage, a ball tank for storing a game ball, a tank rail for receiving a game ball from the ball tank at one end and flowing the game ball toward the other end, predetermined according to a command command A ball game machine in which a discharge device that allows only a number of game balls to pass is provided with a case rail that guides the game balls from the tank rail, and each of these passage members contains a conductive component at least in the surface layer portion In
  The flow rate of the game ball flowing down the game ball passage is faster than the ball tank and the tank rail as the passage members upstream of the game ball passage, and the load of the game ball on the passage surface is increased. The case rail as the passage member in the downstream part is more conductive component content than the ball tank and the tank rail.Reduce.
[0012]
  The game ball is accelerated while flowing down the tank rail of the game ball passage, and the flow speed is increased when entering the case rail in the downstream portion. Since the flow speed of the game ball is fast on the case rail, the load on the passage surface due to the impact on the passage surface of the game ball passage and the centrifugal force is large. In particular, in the case rail, the game ball is guided to the discharging device, so that the direction of the game ball passage is greatly changed, and at this time, the load on the passage surface of the game ball passage becomes large. The larger these loads, the greater the friction between the path of the game ball passage and the surface of the game ball, and the greater the friction at the case rail downstream of the game ball passage. Case railThen, the friction between the passage surface and the surface of the game ballBig part,The conductive component is particularly easily rubbed from the surface of the game ball passage, but since the content of the conductive component is reduced, the conductive component is actually rubbed off.The conductive component that can be suppressed and is rubbed from the path surface of the game ball path is very small.
[0014]
  Upstream of the game ball passageBall tank and tank railIncreases the content of conductive components and has high static eliminating ability. Therefore, the upstream part of the game ball passageBall tank and tank railEven if a lot of game balls that are ground and charged with static electricity flow in, the static electricity is removed well.
[0015]
  And upstream of the game ball passageBall tank and tank railHowever, since the flow velocity of the game ball is still slow, the load on the passage surface due to the impact on the passage surface of the game ball passage and the centrifugal force is small. The larger these loads, the greater the friction between the surface of the game ball passage and the surface of the game ball.Ball tank and tank railThen the friction is small. Therefore, even if the content of the conductive component is large, the conductive component is rubbed from the passage surface of the game ball passage.
[0016]
  Case rail downstream of the game ball passageThe content of the conductive component is small, but in the upstream part of the game ball passageBall tank and tank railSince the static electricity is well removed, the necessary static electricity removal capability can be ensured.
[0018]
Thereby, a sufficient static electricity removing effect can be achieved while preventing adhesion of the conductive component to the game ball or the like.
[0021]
  Claim 2In the described invention, an iron game ball is launched on the surface of the game board, and by returning the fired game ball, the game ball as a prize ball is caused to flow down the game ball passage provided behind the game board, Payout from the supply port that opens below the game boardConfiguration,
  As a passage member constituting the game ball passage, a ball tank for storing a game ball, a tank rail for receiving a game ball from the ball tank at one end and flowing the game ball toward the other end, predetermined according to a command command In a ball game machine in which a discharge device that allows only a number of game balls to pass is provided with a case rail that guides the game balls from the tank rail, and each of these passage members contains a conductive component.
  The flow rate of the game ball flowing down the game ball passage is faster than the ball tank and the tank rail as the passage members upstream of the game ball passage, and the load of the game ball on the passage surface is increased. The case rail as the passage member in the downstream portion is made of a material that has higher scratch resistance than the ball tank and the tank rail, and has a conductive component present uniformly.Constitute.
[0022]
  In the ball tank and tank rail upstream of the game ball passage, the flow speed of the game ball is still slow, so that the friction between the game ball passage surface and the surface of the game ball is small. Therefore, the ball tank and tank rail upstream of the game ball passageAlthough the scratch resistance is low, the conductive component rubbed from the passage surface of the game ball passage is very small. Accordingly, the content of the conductive component can be increased.
[0023]
  In the case rail in the downstream part of the game ball passage, the flow speed of the game ball is fast, so that the friction between the path surface of the game ball passage and the surface of the game ball is large, but the case rail in the downstream part of the game ball passage is resistant to the case rail. Since the scuffing property is high, the conductive component that is rubbed from the passage surface of the game ball passage is very small. Accordingly, the content of the conductive component can be increased.
[0024]
Thereby, a sufficient static electricity removing effect can be achieved while preventing adhesion of the conductive component to the game ball or the like. In addition, since an expensive material having high scratch resistance is used only for some of the passage members, the cost can be reduced accordingly.
[0025]
  Claim 3In the described invention,An iron game ball is launched on the surface of the game board, and as a result of the returned game ball, the game ball as a prize ball is caused to flow down the game ball passage provided behind the game board and below the game board. It is the composition which pays out from the supply port which opens,
  As a passage member constituting the game ball passage, a ball tank for storing a game ball, a tank rail for receiving a game ball from the ball tank at one end and flowing the game ball toward the other end, predetermined according to a command command In a ball game machine in which a discharge device that allows only a number of game balls to pass is provided with a case rail that guides the game balls from the tank rail, and each of these passage members contains a conductive component.
  The flow rate of the game ball flowing down the game ball passage is faster than the ball tank and the tank rail as the passage members upstream of the game ball passage, and the load of the game ball on the passage surface is increased. The case rail as the passage member in the downstream portion is made of a material having higher scratch resistance than the ball tank and the tank rail and having the conductive component uniformly present, and the content of the conductive component contained Is configured to be smaller than the ball tank and the tank rail.
[0026]
  Upstream of the game ball passageBall tank and tank railThen, the flow speed of game balls is still slow,Friction between the path surface of the game ball passage and the surface of the game ball is small.Therefore, the upstream part of the game ball passageBall tank and tank railEven if the scratch resistance is low, the conductive component that is rubbed from the passage surface of the game ball passage is very small. Accordingly, the content of the conductive component can be increased.
[0027]
  Downstream part of the game ball passageCase railSince the flow speed of the game ball is fast, the friction between the path surface of the game ball path and the surface of the game ball is large, but the game ball pathDownstream case railIs scratch resistantSince it is high and the content of the conductive component is small, the conductive component that is rubbed from the passage surface of the game ball passage can be made smaller.
[0028]
Thereby, a sufficient static electricity removing effect can be achieved while preventing adhesion of the conductive component to the game ball or the like. In addition, since an expensive material having high scratch resistance is used only for some of the passage members, the cost can be reduced accordingly.

The ball tank 4, the tank rail 5 and the case rail 6 are grounded by a ground wire (not shown).
[0066]
A passage end downstream of the S-shaped passages 6a to 6c of the case rail 6 is connected to an inlet 171a of a ball lending device 171 through a connecting passage 191 through one ball lending passage 6a. The two passages 6 b and 6 c communicate with the inlet 172 a of the prize ball payout device 172. The game ball outlet 171 b of the ball lending device 171 and the game ball outlet 172 b of the prize ball payout device 172 communicate with the game ball pool 193 via the discharge passage 192. The game ball pool 193 communicates with the supply port 122 of the upper tray 121.
[0067]
When the command command is output from the prize ball control device 162 in response to the operation of the ball lending button 131 as described above, the ball lending device 171 allows passage of a predetermined number of game balls from the inlet 171a to the outlet 171b, The ball is supplied to the upper tray 121 as a rental ball (the arrow in FIG. 4 indicates the flow path of the rental ball). In addition, the prize ball payout device 172 outputs a command command from the main controller 161 when a game ball enters the above-described winning holes 221 and the like of the game board 211, and a predetermined number of game balls from the entrance 172a to the exit 172b. Is allowed to pass and is paid out to the upper tray 121 as a prize ball.
[0068]
The operation of this pachinko machine will be described. During ball lending, the balls are sequentially discharged from the ball lending device 171 to the upper tray 121 as described above. When the supply of balls is started, the game balls flow down toward the ball lending device 171 through the ball lending cage 5a and the ball lending S-shaped passage 6a. On the other hand, when there is a winning, a predetermined number of game balls are paid out from the winning ball payout device 172 to the upper tray 121 according to the type of winning. When the supply of the prize balls is started, the game balls flow down toward the prize ball payout device 172 through the prize ball cages 5b and 5c and the prize ball S-shaped passages 6b and 6c.
[0069]
Here, in the range from the ball tank 4 to the tank rail 5 in the game ball supply passage 3, the game ball flows down while sliding on a gentle inclined surface with acceleration, and the flow down speed is the fastest before the case rail 6. Become. In this state, it passes through the S-shaped passages 6a to 6c of the case rail 6. Therefore, in the S-shaped passages 6a to 6c, if there is a minute undulation on the passage surface, a large impact corresponding to the momentum of the game ball is applied to the passage surface. Further, in the case rail 6, the passages 6a to 6b are S-shaped, so that a centrifugal force acts on the game ball at the curved portion, and a large load is applied to the passage surface. For this reason, the friction between the surface of the game ball and the passage surface is small in the ball tank 4 and the tank rail 5 and large in the case rail 6.
[0070]
The ball tank 4 and the tank rail 5 that are upstream of the game ball supply passage 3 have a higher carbon content than the case rail 6 and have a high static electricity removal capability. Therefore, even if a lot of game balls which are ground and charged with static electricity flow into the ball tank 4 from the replenishment basket, the static electricity is removed well.
[0071]
As described above, since the friction between the surface of the game ball and the passage surface is small in the ball tank 4 and the tank rail 5, the ball tank 4 and the tank rail 5 have a high carbon content and the base resin has a high resistance. Even with ABS having low scratching properties, the amount of carbon that is rubbed by the game ball from the passage surface of the game ball supply passage 3 is very small.
[0072]
On the other hand, the case rail 6 has a low carbon content, but since the static electricity is satisfactorily removed by the ball tank 4 and the tank rail 5, the necessary static electricity removal capability can be ensured.
[0073]
As described above, the case rail 6 has a large friction between the surface of the game ball and the passage surface, but the case rail 6 is a polycarbonate with a low carbon content and a base resin having good scratch resistance. The carbon that is rubbed by the game balls from the passage surfaces of the S-shaped passages 6a to 6c is very small.
[0074]
Thereby, it is possible to achieve a sufficient static electricity removing effect while preventing carbon from adhering to a game ball or the like. The static electricity charged in the game ball is almost completely removed by the ball tank 4, the tank rail 5, and the case rail 6 before reaching the ball lending device 171 and the prize ball payout device 172, and noise is generated in the control devices 161-166. Can be prevented from entering.
[0075]
It should be noted that a mechanism board 151 that constitutes a ball lending device 171, a prize ball payout device 172, a connection passage 191, a game ball reservoir 193, a game ball return passage 194, and the like, which are downstream of the case rail 6 of the game ball passage 3. The passage member is made of a resin containing an antistatic agent so that the game ball is not charged again.
[0076]
The amount of carbon to be contained is not limited to those described above, and an optimal value should be obtained experimentally as appropriate. According to the experiments by the inventors, good results were obtained when the ball tank 4 and the tank rail 5 were 11 to 15% by weight and the case rail 6 was 7 to 10% by weight.
[0077]
  In addition, carbon is a material stage before the manufacture of the passage member such as the ball tank 4.Base resinIt is preliminarily contained in the passage member and exists homogeneously in the passage member, but may be present only in the surface layer portion of the passage member that comes into contact with the game ball. For example, the passage member is made of a synthetic resin that does not contain a conductive component. After coating with a coating agent containing fine particles of a conductive metal oxide film, which is a conductive component, in a solution such as olefin or polyester, a conductive coating film that is a surface layer portion is applied.It may be formed.
[0078]
Further, the ball tank 4 and the tank rail 5 are made of ABS, and the case rail 6 is made of polycarbonate. However, when the degree of dirt required and the amount of static electricity required to be removed by the case rail 6 are small. The case rail 6 may be ABS.
[0079]
Further, the carbon content may be the same in the ball tank 4, the tank rail 5, and the case rail 6, depending on the required total static electricity removal amount. The case rail 6 is made of polycarbonate, which is more scratch resistant than ABS, which is the material of the ball tank 4 and the tank rail 5, so that even if the load applied to the passage surface by the game ball on the case rail 6 is large, the carbon is rubbed. Can be prevented well.
[0080]
Also, the base resin of the ball tank 4 and the tank rail 5 and the base resin of the case rail 6 can be selected as appropriate according to various conditions such as cost. It is only necessary to use one having higher scratch resistance than the base resin of 4 and the tank rail 5.
[0081]
Also, the ball rail 4 and the tank rail 5 have a faster flow rate of the game ball in the tank rail 5, so that the base of the carbon content is such that the ball tank 4> the tank rail 5> the case rail 6. Regarding the scratch resistance of the resin, the sphere tank 4 <tank rail 5 <case rail 6 may be satisfied. Alternatively, the carbon content and the scratch resistance of the base resin may be changed in the passage member. For example, the downstream side of the tank rail 5 is such that the carbon content is lower and the scratch resistance of the base resin is higher.
[0083]
The present invention can also be applied to a cash machine in which only prize balls flow in the game ball passage, and an arrange ball machine.
