Abstract

PROBLEM TO BE SOLVED: To prevent game balls from rubbing electroconductive components off eventually staining the game balls, and the like, without reducing antistatic functions when the game balls pass through a game ball path in a Pachinko game machine in which path members of the game ball path are impregnated with electroconductive components for removing static electricity of the game balls to be supplied as at least prize balls after polished outside. SOLUTION: The electroconductive components are less in the content thereof for a path member 6 on the downstream side and with a higher resistance to scratching than those of path members 4 and 5 on the upstream side of the game ball path 3. On the upstream side, the downflow speed of the game balls is less, and so, the friction is smaller, the electroconductive components are inhibited from being rubbed off even when sufficient amounts of the electroconductive component are arranged to develop sufficient antistatic functions. On the downstream side where the downflow speed is higher, the less amounts of the electroconductive components and the higher resistance to scratching combinedly inhibit the electroconductive components from being rubbed off.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine,
In particular, the present invention relates to a countermeasure against static electricity charged on a game ball.

[0002]

2. Description of the Related Art A ball-and-ball game machine is a game machine that fires a game ball on the board of a game board by a player's operation and pays out a game ball as a prize ball according to the return of the game ball. Pachinko gaming machines that pay out prize balls when they enter a predetermined winning opening, and arrangement ball machines that pay out prize balls according to combinations of entrances into which game balls enter, are widely used. These pachinko and arranging ball machines have a diameter of about 1 as a game ball.
A so-called pachinko ball made of 1 mm iron is used.

[0003] In addition to a device for processing a game ball entered into a winning opening or the like and executing a payout of a prize ball, a variety of effects are provided to make the progress of the game more interesting. It is equipped with a device that controls the display and sound output. Today, these devices are constituted by an electronic control unit constituted by a microcomputer or the like. In a ball game arcade, a number of game machine installation islands in which a number of such ball game machines are arranged side by side are laid out in a ridge shape, so that a large number of gamers can be accepted.

[0004] By the way, the above-mentioned gaming balls used in pachinko gaming machines and arranged ball machines are returned from the players to the playground side in exchange for prizes after the game, or collected as out-balls, and then lent balls again. It is used as a prize ball and circulates in the game hall. In the middle of this circulation, the game ball is polished by a polishing device commonly installed on the game ball installation island behind the game machine before being provided to the game machine,
Rust and dirt are removed so that the progress of the game and the payout of prize balls are not hindered, and the shiny game balls allow the player to enjoy the game comfortably.

In the process of supplying the game balls to the game machine again, between the game balls and the abrasive of the polishing device, between the game balls and the passage surface of the game ball passage through which the game balls flow, Friction occurs between the comrades, and the surface of the game ball is charged with static electricity. If the static electricity is discharged when the game ball passes through the inside of the gaming machine, there is a possibility that a malfunction or a failure of the electronic control device may be caused by noise generated thereby.

As a countermeasure against noise due to static electricity, Japanese Patent Publication No. 5-56993 discloses that a game ball passage in a game machine through which the game machine is distributed is made of a conductive synthetic resin containing a conductive component and grounded. There is something. In this technique, carbon particles are used as a conductive component.

[0007]

By the way, in order to obtain a sufficient effect of removing static electricity, the content of the conductive component may be increased, but when the content is increased, the game ball which has been polished and has regained its luster is required. However, in the course of flowing down the gaming ball passage of the gaming machine, the passage surface is worn by the gaming ball itself, eventually being stained by the rubbed conductive component, which may eventually stain the player or the gaming machine itself. was there.

The passage member contains carbon-based ultrafine fibers as a conductive component, and discharges static electricity into the air by generating corona discharge between the tip of the carbon-based ultrafine fibers and the surface of the game ball. According to this technique, there is almost no problem of adhesion of dirt by forming carbon into an ultrafine fibrous form. However, the use of expensive ultrafine fibers requires a significant increase in cost as compared with the case where conductive fine particles such as carbon particles are used as a conductive component, which is not always practical.

It is also conceivable to use a material having high hardness and good scratch resistance for the passage member to suppress the abrasion of the passage surface by the game ball, but a material having good scratch resistance, such as polycarbonate, is expensive. In the end, the cost rises.

The present invention has been made in view of the above circumstances, and provides a ball-and-ball game machine in which a conductive component is little attached to a game ball or the like and which can obtain a sufficient static electricity removing effect. With the goal.

[0011]

According to the first aspect of the present invention, an iron game ball is fired on a game board surface, and a game ball as a prize ball is placed behind the game board according to the result of the fired game ball. In a ball game machine that allows a game ball passage provided in a game ball passage to flow down and pays out from a payout opening that opens below a game board, at least a surface layer portion of a passage member constituting the game ball passage contains a conductive component. At the same time, the content of the conductive component is reduced as the load of the game ball on the passage surface of the game ball passage increases.

At a portion where the load of the game ball on the passage surface of the game ball passage is large, the friction between the passage surface and the surface of the game ball is large, and accordingly, the conductive component is particularly rubbed from the passage surface of the game ball passage. Although it is easy to take, the content of the conductive component is reduced, so that the conductive component can be prevented from actually being rubbed. On the other hand, since the content of the conductive component is increased in the portion where the conductive ball is hard to be rubbed and the load of the game ball on the passage surface is small, the high static electricity removing ability is exhibited in such portion, so that the static electricity can be satisfactorily discharged. Remove. As a result, a sufficient static electricity removing effect can be achieved while preventing the conductive component from adhering to a game ball or the like.

[0013] According to the second aspect of the present invention, in the configuration of the first aspect, the content of the conductive component is reduced toward the downstream of the game ball passage.

The upstream portion of the game ball passage has a high content of conductive components and has a high static electricity removing ability. Therefore,
Even if a large amount of statically charged game balls are polished into the upstream portion of the game ball passage, static electricity can be satisfactorily removed.

Since the flow speed of the game ball is still low upstream of the game ball passage, the load due to impact on the passage surface of the game ball passage and the load on the passage surface due to centrifugal force are small. The greater the load, the greater the friction between the passage surface of the game ball passage and the surface of the game ball, and therefore the smaller the friction in the upstream portion of the game ball passage. Therefore, even if the content of the conductive component is large, the conductive component scraped from the passage surface of the game ball passage is small.

On the other hand, the content of the conductive component is small in the downstream portion of the game ball passage, but the static electricity is well removed in the upstream portion of the game ball passage, so that the necessary static electricity removing ability can be secured. .

In the downstream portion of the game ball passage, the flow speed of the game ball is high, so that the friction between the passage surface of the game ball passage and the surface of the game ball is large, but the content of the conductive component is small.
A small amount of the conductive component is removed from the passage surface of the game ball passage.

As a result, a sufficient static electricity removing effect can be achieved while preventing the conductive component from adhering to a game ball or the like.

According to a third aspect of the present invention, in the configuration of the second aspect of the present invention, as the passage member, a ball tank for storing game balls, and one end receiving game balls from the ball tank toward the other end. A tank rail for flowing game balls, and a discharge device for passing only a predetermined number of game balls in response to a command command, a case rail for guiding game balls from the tank rails are provided, and a conductive component of the case rail is provided. The content is lower than that of ball tanks and tank rails.

The game ball is accelerated while flowing down the tank rail, and when flowing into the case rail, the flowing speed is high. In the case rail, the game ball path changes greatly in order to guide the game ball to the discharge device. At this time, the load on the passage surface of the game ball passage also becomes large. Therefore, the case rail is desirable as a portion for reducing the content of the conductive component, and exhibits a great effect of preventing the game balls from being stained.

According to the fourth aspect of the present invention, an iron game ball is fired on the game board surface, and a game ball as a prize ball is provided behind the game board according to the return of the fired game ball. In a ball game machine that allows a passage to flow down and pays out from a payout opening that opens below a game board, at least a surface layer portion of a passage member that constitutes the game ball passage contains a conductive component, and the passage member includes the passage member. The game ball passage is constituted by a plurality of passage members which divide the game ball passage into a plurality of passage members. Of the passage members, the passage member having a larger load on the passage surface is made of a material having higher scratch resistance.

The smaller the load on the passage surface of the game ball passage, the smaller the friction between the passage surface of the game ball passage and the surface of the game ball. Therefore, even though the passage member having a small load on the passage surface of the game ball passage has low scratch resistance, the conductive component scraped from the passage surface of the game ball passage is small.
Accordingly, the content of the conductive component can be increased.

In a passage member having a large load on the passage surface of the game ball passage, the friction between the passage surface of the game ball passage and the surface of the game ball is large, and the conductive component scraped off from the passage surface of the game ball passage is Insignificant.

As a result, a sufficient static electricity removing effect can be achieved while preventing the conductive component from adhering to the game ball or the like. In addition, since an expensive material having high scratch resistance is not used for only some of the passage members, the cost can be reduced accordingly.

According to a fifth aspect of the present invention, in the configuration of the fourth aspect, the plurality of passage members are constituted by a plurality of passage members that divide the game ball passage into a plurality in the downflow direction of the game ball, Among the plurality of passage members, a member located downstream of the game ball passage is made of a material having higher scratch resistance.

Since the flowing speed of the game ball is still low upstream of the game ball passage, the load due to impact on the passage surface of the game ball passage and the load on the passage surface due to centrifugal force are small.
The greater the load, the greater the friction between the passage surface of the game ball passage and the surface of the game ball, and therefore the smaller the friction in the upstream portion of the game ball passage. Therefore, even though the passage member forming the upstream portion of the game ball passage has low scratch resistance, the conductive component scraped from the passage surface of the game ball passage is small. Accordingly, the content of the conductive component can be increased.

In the downstream portion of the game ball passage, the flow speed of the game ball is high, so that the friction between the passage surface of the game ball passage and the surface of the game ball is large, but the passage member forming the downstream portion of the game ball passage is Since the abrasion resistance is high, the conductive component scraped from the passage surface of the game ball passage is small. Accordingly, the content of the conductive component can be increased.

As a result, a sufficient static electricity removing effect can be achieved while preventing the conductive component from adhering to a game ball or the like. In addition, since an expensive material having high scratch resistance is not used for only some of the passage members, the cost can be reduced accordingly.

According to a sixth aspect of the present invention, in the configuration of the fifth aspect of the present invention, as the passage member, a ball tank for storing game balls, and one end receiving game balls from the ball tank toward the other end. A tank rail for flowing game balls, and a discharge device for passing only a predetermined number of game balls in response to a command command, a case rail for guiding the game balls from the tank rails are provided. It is made of a material having higher scratch resistance than the tank rail.

The game ball is accelerated while flowing down the tank rail, and the flowing speed is high when entering the case rail. In the case rail, the game ball path changes greatly in order to guide the game ball to the discharge device. At this time, the load on the passage surface of the game ball passage also becomes large. The case rail is desirable as a passage member made of a material having high abrasion resistance, and has a great effect of preventing a game ball from being stained.

A passage end downstream of the S-shaped passages 6 a to 6 c of the case rail 6 is connected to one connection passage 19
1 and communicates with the entrance 171a of the ball lending device 171 through which two passages 6b and 6c for prize balls are provided.
It is in communication with 72 inlets 172a. Ball rental device 171
Exit 171b of the game ball of the prize ball payout device 172
The exit 172b of the game ball communicates 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.

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 enters the entrance 1 for a predetermined number of game balls.
The passage from 71a to the exit 171b is permitted, and 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). The prize ball payout device 172 outputs a command command from the main control device 161 when a game ball enters the above-mentioned winning port 221 or the like of the game board 211, and from the entrance 172a to the exit 172b for a predetermined number of game balls. Is allowed, and the ball is paid out to the upper tray 121 as a prize ball.

The operation of the pachinko gaming machine will be described. At the time of 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 the ball rental starts, the game ball flows down the ball rental gutter 5a and the ball rental S-shaped passage 6a toward the ball rental device 171. on the other hand,
When there is a prize, a predetermined number of game balls are paid out from the prize ball payout device 172 to the upper tray 121 according to the type of the prize. When the supply of the prize ball is started, the troughs for the prize ball 5b, 5c,
Game balls flow down the prize ball S-shaped passages 6b and 6c toward the prize ball payout device 172.

Here, in the range from the ball tank 4 to the tank rail 5 in the game ball supply passage 3, the game ball slides down along a gentle slope with acceleration, and flows down before the case rail 6. Is the fastest. 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 slight undulation on the passage surface, a large impact according to the momentum of the game ball is applied to the passage surface. In case rail 6, passage 6
Since a to 6b are S-shaped, a centrifugal force acts on the game ball in the curved portion, and a large load is applied to the passage surface. Therefore, the friction between the surface of the game ball and the passage surface,
It is small in the ball tank 4 and the tank rail 5 and large in the case rail 6.

The ball tank 4 and the tank rail 5, which are the upstream part of the game ball supply passage 3, have a higher carbon content than the case rail 6 and have a high static electricity removing ability.
Therefore, even if a large amount of polished game balls are polished and flow into the ball tank 4 from the supply gutter, the static electricity is satisfactorily removed.

Since the friction between the surface of the game ball and the passage is small in the ball tank 4 or the tank rail 5 as described above, the ball tank 4 or the tank rail 5 has a large carbon content, Even if the resin is ABS with low scratch resistance, a small amount of carbon is rubbed by the game balls from the passage surface of the game ball supply passage 3.

On the other hand, the case rail 6 has a low carbon content, but the static electricity is removed well by the ball tank 4 and the tank rail 5, so that the necessary static electricity removing ability can be secured.

As described above, in the case rail 6, the friction between the surface of the game ball and the passage surface is large, but the case rail 6 has a low carbon content and the base resin has good scratch resistance. Therefore, the amount of carbon scraped by the game balls from the passage surfaces of the S-shaped passages 6a to 6c is very small.

As a result, a sufficient static electricity removing effect can be achieved while preventing carbon from adhering to a game ball or the like. The static electricity charged on the game ball is transferred to the ball rental device 17.
Before reaching the prize ball payout device 172 or the prize ball payout device 172, the ball is almost completely removed by the ball tank 4, the tank rail 5, and the case rail 6, so that noise can be prevented from entering the control devices 161 to 166.

It should be noted that the ball lending device 171 and the prize ball payout device 17 are located downstream of the case rail 6 in the game ball passage 3.
2. Passage members such as the mechanism board 151 constituting the connection passage 191, the game ball pool 193, the game ball return passage 194, and the like are made of a resin containing an antistatic agent so that the game balls are not charged again. I have.

The amount of carbon contained is not limited to those described above, but it is better to experimentally find the optimum value. According to 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.

Although carbon is contained in the base resin beforehand and homogeneously present inside the passage member at the stage of the material before the production of the passage member such as the ball tank 4, the passage member which comes into contact with the game ball is formed. May be present only in the surface layer portion of, for example, after the passage member is manufactured from a synthetic resin containing no conductive component, fine particles of a conductive metal oxide film that is a conductive component in a solution of olefin, polyester, or the like. May be applied to form a conductive coating film which is a surface layer portion. In this case, in the same passage member, the content of the conductive component may be increased continuously or stepwise toward the downstream side.

The ball tank 4 and the tank rail 5 are made of ABS, and the case rail 6 is made of polycarbonate.
When the amount of static electricity required to be removed by the above is small, the case rail 6 may be made of ABS.

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 having higher scratch resistance than ABS, which is a 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, carbon is rubbed. Can be satisfactorily prevented.

The base resin of the ball tank 4 and the tank rail 5 and the base resin of the case rail 6 are also
It can be appropriately selected according to various conditions such as cost. If the base resin of the case rail 6 is more scratch-resistant than the base resin of the ball tank 4 and the tank rail 5, Good.

Further, between the ball tank 4 and the tank rail 5, the flow rate of the game ball is higher in the tank rail 5 so that the ball tank 4> tank rail 5> case rail 6 in terms of carbon content. Furthermore, the scratch resistance of the base resin may be set so that ball tank 4 <tank rail 5 <case rail 6. Alternatively, the content of carbon and the abrasion resistance of the base resin may be changed in the passage member. For example, the lower the downstream side of the tank rail 5, the lower the carbon content, and the higher the abrasion resistance of the base resin.

Further, depending on the way of setting the path of the game ball supply passage, if there is a portion where the load of the game ball is large even on the upstream side, the content of the conductive component there is reduced, and the load of the game ball is small even on the downstream side. If there is a portion, the content of the conductive component therein may be increased.

The present invention can also be applied to a cash machine in which only a prize ball flows in a game ball passage or an arranged ball machine.
