Description

[Detailed description of the invention] [Technical field to which the invention pertains] The present invention relates to an antistatic mechanism for pachinko balls, and in particular, to discharge static electricity charged on pachinko balls during the process of passing through the award ball ejection mechanism board of a pachinko game machine. The present invention relates to an antistatic mechanism for pachinko balls that enables the use of pachinko balls.

[Technical background of the invention]

Generally, the prize balls that are paid out to players in pachinko gaming machines are replenished into the upper tank of each pachinko gaming machine after the balls shot by the players are collected for each island and polished by a polishing device. In addition, in recent polishing devices, inclusions such as foamed resin are mixed into pachinko balls for polishing, and the polishing speed is high, so pachinko balls are often charged with static electricity during this polishing.

Also, in each pachinko machine, each time a winning ball is generated, the prize balls stored in the upper tank are returned to the player from the prize ball outlet via the tank chute, lead-out chute, prize ball discharge device, etc. However, since the prize ball ejection path is usually made of synthetic resin, charge is often accumulated on the pachinko ball even during the process of passing through each of the above-mentioned prize ball delivery paths.

Although the amount of charge that is charged to each individual pachinko ball is extremely small, if a large number of pachinko balls charged in this way are paid out as prize balls, players may receive an electric shock when they touch the prize balls. , you may feel extremely uncomfortable.

[Purpose of invention]

The present invention has been made in view of the current situation, and aims to provide an anti-static mechanism for pachinko balls that can eliminate the discomfort of players by discharging charges on prize balls.

[Summary of the idea]

In summary, the antistatic mechanism for pachinko balls of the present invention pivots a prize ball ejecting mechanism board having at least an upper tank for storing prize balls in the upper part to a conductive frame attached to the back of the front frame, The present invention is based on a pachinko game machine in which the ball ejection port of the prize ball ejection mechanism board is connected to a tray provided on the front surface of the front frame: the prize ball ejection mechanism board is pivotally supported on the conductive frame. A frame side piece and a prize ball ejection mechanism side piece constituting a hinge are each made of a conductive material: a conductive part is placed midway inside the falling path of pachinko balls from the upper tank to the ball ejection port. laying a conductive plate-like member, and making the conductive plate-like member electrically conductive with the prize ball ejection mechanism side piece of the hinge: the prize ball ejection mechanism side piece of the hinge and the frame side piece; The frame side piece of the hinge and the conductive frame are electrically connected.

That is, in the present invention, the electrical charge on the pachinko balls is transmitted to the conductive plate member in the process of flowing down from the upper tank to the ball ejection port, and the ball ejection mechanism side part and the frame side part that make up the hinge are Since the ball is discharged into the conductive frame via the conductive frame, even if the player touches the ejected prize ball, he or she will not feel discomfort due to electric shock.

[Example of idea]

An embodiment of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a diagram showing the back mechanism of a prize ball ejection system of a pachinko game machine according to an embodiment of the present invention, and the flow of pachinko balls will be explained with reference to FIG.

First, an upper tank 2 is placed at the top of each pachinko game machine 1, and the prize balls stored in this upper tank 2 are sent to a tank chute 3a and a corner joint 60.
and the prize ball ejecting device 4 via the deriving chute 3b.
A predetermined number of balls (the number of balls paid out for each winning ball) is supplied to the ball sheath 4a in the prize ball ejecting device 4,
For example, 15 items) are retained.

On the other hand, the pachinko balls that have entered any of the winning areas flow through the winning ball collecting gutter A1 into the single player chain 6, and are released while rotating the series player 6 clockwise by the weight of the pachinko ball. It flows into the chute 7, naturally falls into the lie detector 8, and is collected outside the aircraft. Also, in the process of falling into the lie detector 8, this pachinko ball causes the crank anchor 9 to rotate clockwise, and as the crank anchor 9 rotates, the claw portion 9a of the crank anchor 9 and the lever 10 are engaged. When the engagement of the dowel pin 10a is released, the lever 10 is moved to the shaft 11.
The other end of the lever 10 pushes up the connecting rod 12 by rotating clockwise around the center by the weight of the pachinko ball.

The upper end of this connecting rod 12 is connected to a rotatable first operating rod 13, the other end of the first operating rod 13 is connected to a second operating rod 14, and the other end of the second operating rod 14 is connected to the ball sheath 4a. is connected to the left end of Therefore, by pushing up the connecting rod 12, the first
The operating punch 13 rotates clockwise, and the second operating punch 1
4, the left end of the ball sheath 4a is pushed down, so the ball sheath 4a rotates counterclockwise, and a predetermined number of pachinko balls stored in the ball sheath 4a are sent to the upper tray outlet via the lead-out path 15. 16 into the upper tray, and the pachinko balls discharged into the upper tray are again supplied to the ball hitting device.

If the upper tray is full at this time, the pachinko balls overflowing to the upper tray are discharged from the tray outlet 70 to the lower tray through the diversion gutter 18.

In addition, the pachinko balls that did not win in any of the winning areas are collected together with the pachinko balls collected from the lie detector 8 as described above, polished by the polishing device, and then replenished into the upper tank 2 as appropriate. .

And as mentioned immediately, tank shoot 3a
The lead-out chute 3b and the lead-out path 15 are made of synthetic resin, and the pachinko balls are polished together with foamed resin in the polishing device, so the process of passing through the pachinko game machine or the in-store replenishment device as described above can be avoided. In the process of passing, the pachinko balls accumulate electric charge, and when a player touches a pachinko ball in the lower tray, the player receives an electric shock due to the static electricity, making him feel extremely uncomfortable.

Therefore, in the present invention, a conductive member is exposed and placed in the flow path of the pachinko ball at any point in the flow path, and this conductive member is connected to a point with a large charging capacity to connect the pachinko ball to the flow path. This makes it possible to release electrical charges.

Therefore, the conductive member can be placed anywhere along the flow path of the pachinko ball described above, but in this example, the existing equipment of the pachinko game machine is effectively used, and a sufficient amount of discharge is required. To obtain the effect, tank chute 3a and lead-out chute 3

The discharge plate 2
Conducts with 0.

Furthermore, a tank chute 3a and a lead-out chute 3
When bending the foot portions 21 of the discharge plates 20 installed in the tank chute 3a and the outlet chute 3b inward, the four connection plates 30 are inserted into the slits formed at the bottoms of the tank chute 3a and the lead-out chute 3b for inserting the foot portions 21. It is applied so that the H-shaped depression is located. Therefore, by bending the foot portion 21 inward,
The connecting plate 30 is held in the foot portion 21 and is in close contact with the outer bottom surfaces of the tank chute 3a and the outlet chute 3b, respectively. As a result, the four discharge plates 20 laid inside the bottom surfaces of the tank chute 3a and the outlet chute 3b are electrically connected to each other via the connection plate 30 and the mesh copper wire 31, and are also connected to the ground plate 40. electrically connected.

By fitting the left ends of the tank chute 3a and the outlet chute 3b, whose bottom surfaces are electrically connected to each other, into the corner joint 60, a flow path from the tank chute 3a to the outlet chute 3 is formed.

Next, FIG. 8 is an exploded perspective view showing the connection state of the ground plate 40, the hinge ground plate 50, and the frame B1 (see FIG. 2). The drop hinge is composed of a prize ball ejection mechanism board side piece 90 and a frame side piece 91.

Next, FIG. 9 is a perspective view showing the configuration of the saucer outlet 70 and the discharge plate 80 laid in the saucer outlet 70. The discharge plate 80 is laid along the inner wall of the saucer outlet 70, and is indicated by diagonal lines in the figure. It shows.

The saucer outlet 70 is made of synthetic resin and is fixed to the lower part of the front frame B (see FIG. 2). To explain its components, the saucer outlet 70
A front flange 71 serves as an attachment member to the front frame B and also fixes the lower tray B4 (see Fig. 2), a ball receiving tube 72 for receiving pachinko balls discharged from the diverter gutter 18, and a ball receiving tube. 72
and a connecting gutter 73 for connecting the front flange 71 and the front flange 71.
and has.

To explain each component in more detail, first, the front flange 71 is attached to the front frame B around the front flange 71, and a screw hole 74 for attaching a saucer B4, for example, is bored therein, and at the approximate center of the upper side. A ball outlet 75 for discharging the prize ball to the lower tray B4 is formed in the part. Further, the ball receiving cylinder 72 has an open top and front surface, and a bottom surface that is inclined toward the front. The connecting gutter 73 is for connecting the front opening of the ball receiving tube 72 and the ball outlet of the front flange 71, and the bottom surface of the connecting gutter 73 is integrated with the bottom surface of the ball receiving tube 72 and extends forward. tilt.

Further, 76 indicates a ball ejecting tube formed integrally with the ball receiving tube 72, and the ball ejecting tube 76 is used to discharge pachinko balls hit by players and pachinko balls remaining in the upper tank 2 at the time of closing to the outside of the machine. belongs to. The front surface of the ball removing tube 76 is in the same plane as the front opening of the ball receiving tube 72.
A rear flange 77 having screw holes for attachment to the frame B1 is integrally formed at the front end of the side wall of the frame B1.

When fixing this saucer outlet 70 to the front frame B (see Fig. 2), first insert the ball into the through hole (not shown) in the lower part of the front frame B (corresponding to the back side of the front decorative plate B5) from behind. Receiving tube 72 and connecting gutter 7

After that, a prize ball ejection mechanism board side piece 90 and a frame side piece 91 forming a drop hinge shown in FIG.
If the front frame B and prize ball ejection mechanism panel C are connected, the upper opening of the ball receiving tube 72 will be located directly below the lower opening of the diversion gutter 18, and the ball can be disposed downward from the diversion gutter 18. The ejected prize ball is placed in the ball receiving tube 72.
The balls fall, pass through the connecting gutter 73 and the ball outlet 75, and are discharged into the lower tray B4.

In this embodiment, the discharge plate 80 installed at the saucer outlet 70 is a bent stainless steel plate, and as shown by diagonal lines in FIG.
The long contacting piece 81, which is formed integrally with the discharge plate 80, is placed along the inner upper part of the side wall of the ball receiving cylinder 72 and the front upper part of the ball receiving cylinder 76, and its tip is attached to the rear flange 77. is coming.

Therefore, when fixing the saucer outlet 70 to the front frame B, the discharge plate 80 is laid on the inner wall of the saucer outlet 70, and the tip of the long contact piece 81 is attached to the rear flange 77.
If the discharge plate 80 is also screwed to the frame B1, the discharge plate 80 will be electrically connected to the frame B1.

Therefore, in the process of flowing down the tank chute 3a and the lead-out chute 3b, the electric charge charged on the pachinko ball is not only discharged to the frame B1 through the above-mentioned path, but also discharged to the frame B1 at the saucer outlet 70 via the discharge plate 80. Therefore, even if the player touches the prize ball, he or she will not feel discomfort due to electric shock.

In addition, in the above, a discharge plate is laid in the tank chute 3a, the lead-out chute 3b, and the saucer outlet 70, and this discharge plate is connected to the frame B1, so that the electric charge charged on the pachinko ball is discharged to the frame B1. Although an example has been shown, the place where the discharge plate is laid is not limited to the above as long as it is on the inner wall of the passage path of the prize ball, and even if it is outside an individual pachinko game machine, for example, it can be used to polish pachinko balls. The charge may be discharged within a chute extending from the polishing machine to the upper tank 2. Further, the discharge destination is not limited to the above as long as it has a sufficiently large charging capacity, and may be connected to the ground, for example. Furthermore, it goes without saying that if the installation location of the discharge plate or the discharge destination changes, the method of connecting the discharge plate and the discharge destination changes.

[Effects of the invention] As explained above, according to the invention, the electric charge on the pachinko ball is discharged to a place with a sufficiently large charging capacity, such as the frame, through the discharge plate installed in the passage path of the pachinko ball. Therefore, even if the player touches the pachinko ball on the tray, there is no risk of electric shock, and the player will not feel uncomfortable due to electric shock.

In addition, as mentioned above, a discharge plate is installed in the tank chute and the lead-out chute, and the charge is discharged to the frame via the hinge for pivotally supporting the prize ball ejection mechanism panel to the frame, so that the discharge plate is not used for discharge. The number of cords is kept to a minimum, and the discharge cords do not obstruct the pivoting of the prize ball ejection mechanism panel relative to the frame.

Furthermore, the present invention makes it possible to reliably secure a charge release path without making any changes to existing pachinko gaming machines, and only by adding a few metal parts.
