Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a game machine such as a pachinko machine, and more particularly, to a part of an overflowing ball guide path for guiding an overflowing game ball to a lower receiving tray by a ball flow path forming member. The present invention relates to a gaming machine in which a conductive plate is laid in a path forming member to prevent a game ball from being charged.

[0002]

2. Description of the Related Art When a launched game ball flows down a game area and wins a prize tool such as an attacker, a ball discharge unit operates to discharge a predetermined number of game balls as a prize ball to an upper tray in front of a pachinko machine. Gaming balls that have won the prize-winning equipment are processed as safe balls and then ejected to the outside of the pachinko machine.Gaming balls that do not win any of the prize-winning equipment enter the out mouth and become out-balls and become pachinko balls. Is discharged outside the machine. Then, the game balls discharged from the pachinko machine are collected by a ball collection gutter provided in the lower part of the island, collected in a ball lifting device, polished while being lifted by the ball lifting device, and polished at the upper part of the island. It is stored in a ball storage tank, is replenished from the ball storage tank to the upper tank of each pachinko machine through a ball supply gutter, and the game balls in the upper tank are discharged to the upper tray as the prize balls described above, or When the ball is discharged to the upper tray as a lending ball and the upper tray becomes full and the game balls falling from the next one cannot fit, it is discharged to the lower tray through the overflow channel branched from the middle of the ball discharge path. Is done.

In many cases, the game balls in the upper tray are fired again as they are, and when the game is finished or when moving to another pachinko machine, the ball is once dropped into the lower tray and then stored in the ball box. . For this reason, the player rarely contacts the game ball in the upper saucer. However, the game balls discharged to the lower saucer are transferred by hand from the lower saucer to the upper saucer when the game balls in the upper saucer are insufficient. At this time, if the game ball is charged, it is shocked by the static electricity at the moment of touch, and therefore, there is discomfort.

For this reason, as described in Japanese Patent Application Laid-Open No. 2000-51488, for example, an antistatic mechanism in a conventional pachinko game machine has a charge removing chamber formed at an outlet side of a lower tray and a metal removing chamber is provided in the charge removing chamber. A conductive plate made of a plate is laid, the conductive fixing material connected to the conductive plate is projected outside the charge removing chamber, one end of a ground wire is connected to the conductive fixing material, and the game board is stored. The other end of the ground wire is connected to a metal game board storage frame, and the static electricity from the conductive plate in the charge removal chamber is guided to the game board storage frame to discharge in the air.

[0005]

However, in the conventional structure in which the static electricity of the conductive plate is guided to the game board storage frame via the ground wire and the game board storage frame discharges in the air,
Since only the air discharges from the game board storage frame, most of the static electricity guided from the conductive plate in the charge removing chamber is charged to the game board storage frame. Since the game board storage frame is a large part, the effect of static electricity on the game board stored in the frame is small, but since the game board has a large number of electronic components, the game board storage frame has a large amount of static electricity. Is not preferable.

Further, since recent pachinko machines take measures against static electricity by themselves, malfunctions caused by static electricity generated by the pachinko machine itself hardly cause a problem. In the connected electronic device, for example, there is a possibility that a malfunction due to static electricity may occur in a measuring device for testing the performance of the prototype.

[0007] Therefore, an object of the present invention is to suppress the charge of the static electricity that escapes to the conductive frame, and the static electricity is caused not only by the gaming machine itself but also by the electronic equipment connected later to the gaming machine. It is an object of the present invention to provide a gaming machine capable of suppressing occurrence of trouble.

Then, when the player operates the ball lending operation unit 31, the ball discharging unit 22 operates to discharge a predetermined number of game balls to the upper receiving tray 6.

The ball guide path 33 overflows from a lower portion of the ball discharge path 23, specifically, a little upstream of the outlet 24 of the ball discharge path 23.
The entrance of the overflow ball guide path 33 is provided with a high step at the branch portion, and when the downstream side of the branch portion (upper saucer 6 side) is free, the game ball from the ball discharge unit 22 discharges the ball. When the game balls from the ball discharge unit 22 are dropped to the branch portion because the upper saucer 6 is filled and the like and the game balls are accumulated in the branch portion, the game balls from the ball discharge unit 22 are branched. , And overflows toward the ball guide path 33. The configuration in which the overflowing game balls flow down to the overflow ball guide path 33 is not limited to the above configuration.

The overflow ball guide path 33 has an outlet at the lower end communicating with the lower tray 7, and overflows the overflow ball into the lower tray 7.
In the present embodiment, the upper flow path 33a formed in the rear mechanism panel 15 and the spherical flow path forming member 34 attached to the lower rear surface of the front frame 2 located below the frame board 12. And an overflow detector (not shown) is provided in the middle of the upper flow path 33a.

The spherical flow path forming member 34 is a box-shaped member formed of a conductive material such as carbon-containing PP (polypropylene), and has a flange attached to the back surface of the front frame 2 as shown in FIGS. Behind the part 40, the ball entrance 41 is opened on the upper surface, and the floor part 42 is inclined downward in one of the left and right directions so that game balls from the ball discharge path 23 side are dropped on the floor part 42 from the ball entrance 41.

The other end of the first ground wire 36 is connected to one lower side (the left side in FIG. 3) of the game board storage frame 10 to connect the ball flow path forming member 34 and the game board storage frame 10 to each other.
And are conducted.

The spherical flow path forming member 34 is formed of a conductive material as described above, and has a large surface area. Therefore, when static electricity is charged, the inner and outer surfaces contacting the static electricity are exposed to the atmosphere. From the atmosphere. That is, the spherical flow path forming member 34 made of conductive polypropylene has a function of discharging static electricity itself. Therefore, the ball discharge path 23 and the safe ball discharge path 47,
Alternatively, when the game balls flowing down from the upper receiving tray 6 into the inside of the ball flow path forming member 34 are charged, the static electricity can be released to the ball flow path forming member 34. When the ball flow path forming member 34 is charged by the static electricity from the game balls, the charge can be reduced by discharging the air from the ball flow path forming member 34 itself to the atmosphere. Through the game board storage frame 10. Therefore, when a charged game ball flows into the ball flow path forming member 34, the static electricity is weakened and then released to the game board storage frame 10, and the charge of the game board storage frame 10 is compared with the conventional case. Can be suppressed.

The flange 40 has a positioning hole 49 and a fastening hole 50. Therefore, when the positioning projections protruding from the flange portion of the frame board 12 are fitted into the positioning holes 49, the positions of the frame board 12 and the spherical flow path forming member 34 can be easily and reliably adjusted to the predetermined positions. . And
In this state, if a screw is inserted into the fixing hole 50 or a staple is driven into the fixing hole 50, it can be easily fixed to a predetermined position on the back surface of the front frame 2.

Further, in this embodiment, as shown in FIG. 5, a spherical flow path auxiliary rib 51 is provided at the opening edge of the spherical flow path forming member 34 at the opening edge serving as the inlet of the ball flow path 41 and the safe ball discharge flow path 47.

The structure is such that game balls (safe balls) from the safe ball flow path can be smoothly introduced into the safe ball discharge flow path 47. As shown on the right side in FIG. 5, a hook-shaped (hook-shaped) wire locking portion 52 is formed on the outer side surface of the spherical flow path forming member 34 by projecting integrally with the spherical flow path forming member 34. It is configured to be able to lock the ground wire, the wiring related to the hit ball launching device, and the like.

The ball falling chamber 43 has a ball inlet 4 opened on the upper surface.
Reference numeral 1 denotes a chamber that communicates with the upper flow path 33a of the back mechanism panel 15, and a surface of the floor portion 42 located at the lower end of the slope is open, and this open portion communicates with the charge removal chamber 46. Therefore, the overflowing sphere that has flowed down in the upper flow path 33a is:
The ball flows into the ball falling chamber 43 from the ball inlet 41 and falls on the floor 42 to convert the flowing direction toward the lower end of the inclined surface.
Due to the downward inclination of 2, it flows down toward the charge removal chamber 46. Then, the overflowing ball that has flowed down vigorously from the upper flow path 33a is weakened when the flowing down direction is changed in the ball falling chamber 43. Further, if the overflowing sphere that has fallen on the floor portion 42 of the sphere falling chamber 43 is charged, as described above, the static electricity is discharged from the inner and outer surfaces of the sphere flow path forming member 34 and weakened, and then the first sphere is discharged. The game board storage frame 10 escapes through the ground wire 36.

In the charge removing chamber 46, the floor portion 44 is inclined downward toward the front and communicates with the lower receiving tray 7 at the ball outlet 53 at the lower end of the inclination. In the present embodiment, the lower end of the rear end standing wall which is the upper end of the inclination is provided. A horizontal storage groove 54 is formed in the portion, a step portion 55 is formed in the middle of the inclination of the floor portion 44, and a floor projection 60 projecting from the flange portion 40 is formed at the lower end of the inclination of the floor portion 44.
Is formed, and a conductive plate 45 having a shape corresponding to the upper surface shape of the floor portion 44 is laid on the floor portion 44. Note that the storage groove 54 is set to be larger than the thickness of the conductive plate 45 but smaller in vertical dimension than the diameter of the game ball so that the game ball does not enter the inside. On the ceiling surface located above the floor portion 44 on the downstream side of the step portion 55, a communication port 62 is formed to communicate with the outlet of the ball removal channel 61 formed in the frame board 12. Therefore, when the ball removing operation section 63 of the upper receiving tray 6 is operated, the game balls in the upper receiving tray 6 flow down the ball removing flow channel 61 of the frame board 12 and flow down from the communication port 62 into the charge removing chamber 46. Specifically, it is discharged into the lower receiving tray 7.

The conductive plate 45 is a plate material such as a stainless steel plate having conductivity. In this embodiment, as shown in FIG.
In addition to forming the step bent portion 64 in accordance with the step of the floor portion 44, the conductive upright portion 65 having a height at which the inclined upper end enters the storage groove 54 is bent into a substantially inverted L-shape.
A fastening hole 66 is opened substantially at the center of the conductive standing portion 65,
A part of the side edge of the step bent portion 64 is cut and bent to form a locking claw 70 protruding rearward. At the lower end of the inclined surface of the conductive plate 45, a tip hooking portion 71 hooked to the floor protrusion 60 is formed downward. It is bent so as to be folded.

In order to attach the conductive plate 45 having such a structure to the floor portion 44 of the charge removing chamber 46, the conductive plate 45 is inserted from the ball outlet 53 side, and the conductive standing portion 65 is stored in the storage groove 54. The hook 71 is hooked on the floor protrusion 60, and the locking claw 70 is locked in the locking hole of the step portion 55. In this state, the conductive fastening member is inserted into the fastening hole 66 of the conductive standing portion 65. When the nut is screwed into the metal screw 72 protruding to the outside through the rear end erecting wall and tightened by tightening the nut, the front end of the conductive plate 45 is hooked on the floor protrusion 60, Can be fixed. In addition, when the conductive plate 45 is inserted from the ball outlet 53 side, the locking claw 70 is locked in the locking hole of the step portion 55 of the floor portion 44, so that the slope does not rise midway. When the conductive plate 45 is mounted, one end of the second ground wire 74 is connected when the nut is screwed into the metal screw 72 projecting to the outside, and the other end of the second ground wire 74 is connected to the game board storage frame. 10
The conductive plate 45 and the game board storage frame 10 are electrically connected to each other by connecting the lower part of the game board to the other side.

When the overflowing ball flows down in the charge removing chamber 46 having such a structure, the overflowing ball flowing down from the ball falling chamber 43 rolls down on the floor 44 toward the ball outlet 53 by inclining. At this time, the static electricity charged on the sphere is released from the conductive plate 45 to the other side of the lower portion of the game board storage frame 10 through the second ground wire 74, and from the conductive plate to the ball flow path forming member 34. The transmitted static electricity is weakened by the ball flow path forming member 34, then escapes to one lower side of the game board storage frame 10 through the first ground wire 36, and is discharged in the air by the game board storage frame 10.

Therefore, the conductive plate 45 of the charge removing chamber 46
The overflowing sphere that flows down and is discharged to the lower receiving tray 7 is weakened in electric charge, thereby preventing electric shock of the player. Further, when the ball flows down on the conductive plate 45, if the flowing force is strong, the ball may be charged again by friction between the balls, friction with the floor portion, or friction with the side wall surface. Since the floor 42 itself of the ball falling chamber 43 is formed of a conductive material, when the ball falls on the floor 42, static electricity is discharged to the floor 42 and the electric charge is weakened. The electrification of the ball discharged to the tray 7 can be reliably removed.

The spherical flow path forming member 34 having conductivity
Before being transmitted to the game board storage frame 10, the static electricity is weakened by the atmospheric discharge of the ball flow path forming member 34, and the static electricity passing through the first ground wire 36 is further reduced to the game board storage frame 1.
Since the static electricity that has passed through the second ground wire on one side of the lower part of 0 is transmitted to the other lower part of the game board storage frame 10, the static electricity does not flow back, and the atmospheric discharge can be efficiently performed in the game board storage frame 10. As a result, the electric charge of the game board storage frame 10 can be suppressed more than before. In short, the other end of the ground wire 36 connected to the flow path forming member 34 is connected to another member in the game board storage frame 10 which is a conductive frame, for example, a ground connection portion for connecting a ground wire from a metal plate or a circuit board. The above-described effect can be expected by connecting to a ground connection portion provided at a site isolated from the ground. Therefore, the effect on the electronic components and the like of the game board stored in the game board storage frame 10 can be suppressed as compared with the related art.

Also, a metal plate is laid on the bottom of the lower receiving tray 7 or the lower receiving tray 7 itself is made of a conductive plastic, so that at least the bottom has conductivity. The conductive plate 45 of the charge removing chamber 46
Of the game balls in the lower tray 7 can be released from the conductive plate 45 to the game board storage frame 10 via the second ground wire 74, so that the player's Electric shock can be prevented.

The embodiments disclosed this time are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

For example, in the above-described embodiment, the spherical flow path forming member 34 is integrally formed of conductive polypropylene, but may be formed of another conductive material. Good. Further, the spherical channel forming member 34
Is fixed to the back surface of the front frame 2 in the above embodiment, but may be fixed to a conductive frame such as a lower portion of the game board storage frame 10. Further, a metal screw is used as a conductive fixing material for fixing the ground wire, but the present invention is not limited to this. The connection of the ground wire may be any connection configuration as long as it can conduct with the connection partner.

The present invention is not limited to a pachinko game machine, but may be an arrangement ball game machine or a sparrow ball game machine.

A static elimination chamber formed of a material and having a conductive plate laid on a floor inclined downward to the lower tray side was formed, and one end of a ground wire was connected to the spherical flow path forming member, and the other end was connected to the conductive frame. Therefore, it is possible to remove the charge of the overflowing ball and to avoid giving the player an uncomfortable feeling due to the electric shock. Since the configuration for removing the charge is simple, the manufacturing process is not unnecessarily complicated. Also, since the ball channel forming member is made of a conductive material, the static electricity from the game ball is discharged into the atmosphere from the inner and outer surfaces of the ball channel forming member to the atmosphere, weakened, and then connected to the conductive frame via the ground wire. Can be missed. Therefore, it is possible to suppress a large amount of static electricity from being charged on the conductive frame.
