Description

  The present invention relates to a gaming machine, and more particularly, to a tank for temporarily storing game balls, a payout device for paying out game balls from the tank as prize balls, and guiding the game balls from the tank to the payout device. The present invention relates to a gaming machine having a rail.

  In recent years, various techniques have been proposed for preventing the influence of static electricity charged on the game ball from affecting the control board on the back of the game board. For example, a tank for storing game balls supplied from islands of a game arcade is formed of conductive plastic, or a conductive metal plate is attached to the bottom of a rail, which is a passage of game balls from the tank, to play a game. There is a method of discharging static electricity charged on a sphere from a tank or a metal plate to the ground (for example, see Patent Document 1).

JP-A-6-39118

  However, since the supply of game balls from the island to the tank and the flow of the game balls on the rail frequently occur each time a ball is lent or won, a large amount of static electricity is generated due to collision or friction between the game balls, and the tank or rail is There is a limit to removal simply by making them individually conductive. If the removal is insufficient, static electricity will act on the tank, rails, and control board around the dispensing device, and the game balls charged with static electricity will enter the dispensing device and become control components in the dispensing device. There is a possibility that static electricity may cause a problem that noise is affected.

  In addition, the manner in which the game balls flow at the time of ball lending or winning is slightly different in each part of the distribution route from the tank to the upper plate. A method of effectively removing static electricity by paying attention to such a difference in the flow state of the game ball in each place has not been proposed in the past.

  Therefore, the present invention has been made to solve the above-described problems, to reliably remove static electricity on the upstream side to the control board, and to reliably protect various control boards and control components in the dispensing apparatus from static electricity. Was adopted.

The gaming machine of the present invention,
A tank for temporarily storing game balls, a payout device for paying out game balls from the tank as prize balls when predetermined conditions are satisfied, and a rail for guiding the game balls from the tank to the payout device. A gaming machine having
The gist is that at least one of the tank and the rail and the dispensing device are formed using resin conductive materials having different resistivity.

  Here, the resistivity refers to an electric resistance value per unit volume of a certain material. The resistivity can be expressed as the reciprocal of the specific conductivity.

  According to the gaming machine of the present invention, the static electricity generated by the flow of the game ball at the time of ball lending or winning is reliably removed before the game ball reaches the payout device. As a result, malfunctions of control components and various control boards provided near the payout device can be reliably prevented.

  It is also preferable to use, for the tank or the rail, a conductive material having a lower resistivity than the conductive material used for the dispensing device. This makes it possible to remove the static electricity generated on the game ball due to the supply from the island at a position close to the supply source of the game ball, and to erroneously control components and various control boards provided near the payout device. The certainty of preventing the operation can be further increased. As a result, even when the control components and various control boards are provided below the tanks and rails, it is possible to prevent the malfunction of the control components and the control boards, and the degree of freedom in the arrangement of the control components and the control boards is improved. Can be increased.

  Both the tank and the rail may be formed using a conductive material made of resin, and a conductive material having a lower resistivity than the conductive material used for the rail may be used for the tank. In this way, the static electricity generated by the game balls supplied from the island colliding with the game balls stored in the tank can be quickly removed in the tank after the occurrence, and at a point where a large amount of static electricity is generated Static electricity can be efficiently removed.

  The rail may be configured by connecting a plurality of rail components, and the plurality of rail components may be formed using resin conductive materials having different resistivities. In this case, the static electricity on the rail can be more positively removed on the rail component side using a conductive material having a low resistivity. For example, if a rail component located near the tank is formed using a conductive material having a small resistivity, static electricity is positively removed at a position away from the dispensing device, so that the dispensing device for a game ball charged with static electricity can be used. Can be reliably prevented from entering.

  The resistivity of the conductive material used for each part of the tank, the rail, the rail parts, and the dispensing device is determined by the magnitude of the contact area between each part and the game ball, and the frequency of collision between the game balls in each part. It is also desirable to set the value according to at least one of the presence or absence of the control component in each part. In this case, the resistivity of the conductive material used for each part is determined by the magnitude of friction between each part and the game ball at the time of ball lending or winning, the frequency of collision between the game balls in each part, the control component The value depends on the degree of influence on the image. Therefore, the static electricity can be effectively removed according to the amount of static electricity generated in each part and the necessity of removing the static electricity. For example, if a conductive material with low resistivity is used for a part used in a place where a large amount of static electricity is generated due to friction or collision, a large amount of static electricity generated in the part can be reliably removed from the part, and charging can be performed. It is possible to effectively prevent the game balls in the state from flowing to parts on the downstream side.

  It is also possible to provide a connecting portion for connecting the tank, the rail and the dispensing device, and a hinge portion for pivotally supporting a part of the gaming machine so as to be openable and closable, wherein the connecting portion and the hinge portion are electrically connected. This is preferable in that static electricity generated by the flow of the game ball at the time of lending or winning can be reliably removed from the game machine through the communication member from the tank, the rail, and the payout device.

  Further, an upper plate for storing game balls paid out by the payout device, and a lower plate for storing game balls paid out exceeding the capacity of the upper plate, wherein the upper plate and the lower plate are made of resin. It may be formed using a conductive material.

  In order to further clarify the configuration and operation of the present invention described above, embodiments of the present invention will be described below based on examples. FIG. 1 is an explanatory diagram showing the features of the present invention using a pachinko gaming machine 10 according to an embodiment of the present invention.

FIG. 5 shows the molding material of each component constituting the payout path of the prize ball and the lending ball and the characteristics thereof. As shown in FIG. 5, in this embodiment, the ball tank 72, the tank rail 73, the case rail 74, the prize ball / ball rental unit 75 and the bell base 77 are made of ABS (acrylonitrile butadiene styrene) or PC The protective covers 76a and 76b are made of an ABS insulating material, and the bell tub cover 78 is made of an ABS antistatic material. In this embodiment, those having an electric resistance per unit volume (hereinafter, referred to as surface resistance) of 10 ⁶ Ω or less are classified as conductive materials, and those having a surface resistance exceeding 10 ⁶ Ω are classified as antistatic materials. I have.

Spherical tank 72, the surface resistivity is molded using 10 ⁰ Omega ABS made of the conductive material A of. In the ball tank 72, when replenishing the game balls B from the ball supply device SE in accordance with the payout of the prize balls or the lending balls, the replenished game balls B are transferred to the game balls B stored in the ball tank 72. Since the collision frequency is high and the contact area between the inside of the tank and the game ball B is large, it is considered that the amount of generated static electricity is particularly large. In addition, since the ball tank 72 is installed on the upstream side of the prize ball / ball rental payout unit 75 including the prize ball / ball rental sensor, if the game ball B flows down while being charged, the prize will be awarded. The operation of the ball / ball rental sensor may be adversely affected. For this reason, in this embodiment, the conductive material A having a small surface resistance value is used for the ball tank 72.

  The tank rail 73 is formed using the same conductive material A as the ball tank 72. In the tank rail 73, in addition to a large contact area between the inside of the rail and the game ball B, the ball supply device SE transfers the game ball B to the ball tank 72 in a state where the game ball B is not stored in the ball tank 72. Since replenishment is performed and the replenished game balls B may collide with the game balls B stored in the tank rail 73, it is considered that a large amount of static electricity is generated. In addition, similarly to the ball tank 72, the tank rail 73 is installed on the upstream side of the prize ball / ball rental payout unit 75 including the prize ball / ball rental sensor. For this reason, in this embodiment, the conductive material A having a small surface resistance value is also used for the tank rail 73.

The case rail 74 is formed using an ABS conductive material C having a relatively large surface resistance value ( ^103.8 Ω) in consideration of the fact that the contact area with the game ball B inside is smaller than the tank rail 73. . Also, the reason why the conductive material C is used instead of the antistatic material and the insulating material is that if the charged game ball B flows down from the tank rail 73, the game ball B is used as it is as a prize ball / lending ball. This is to prevent entry into the payout unit 75 and to prevent static electricity from acting on the prize ball / ball loan sensor.

The prize ball / ball rental payout unit 75 includes a PC-made conductive material having an intermediate surface resistance (10 ² Ω) between the conductive material A and the conductive material C, including the portion where the prize ball / ball rental sensor is embedded. It is formed using the material B. The frequency of collision between the game balls B in the prize ball / ball rental unit 75 and the contact area with the game ball B are almost equal to those of the case rail 74, and the amount of static electricity generated in the prize ball / ball rental unit 75 is It is considered that the inside of the case rail 74 is almost the same. On the other hand, in the prize ball / ball lending unit 75, there is a prize ball / ball lending sensor, which is a component for controlling the number of prize balls and the number of balls to be paid out. It is necessary to surely prevent the static electricity of the game balls B from acting on the prize ball / ball rental sensor when the player enters the ball rental unit 75. Therefore, in the present embodiment, the conductive material B having a smaller surface resistance value than the case rail 74 is used for the prize ball / ball rental payout unit 75.

  The suzuki base 77 is installed on the downstream side of the prize ball / ball rental payout unit 75 including the prize ball / ball rental sensor, and has a small influence on the malfunction of the prize ball / ball rental sensor. It is formed using a conductive material C having an extremely large surface resistance value. The reason why the conductive material C was used instead of the antistatic material or the insulating material was to remove the static electricity in the suzuki base 77 from the game ball B as a prize ball or a lending ball, and to pay it out to the upper plate 24. is there.

On the other hand, the protective covers 76a and 76b attached to the prize ball / ball rental unit 75 and the bell cover 78 attached to the bell base 77 are made of an ABS insulating material A (10 ¹⁶ Ω) having a large surface resistance. ) And molded using antistatic material A (10 ¹¹ Ω). The protective covers 76a and 76b and the bell cover 78 are made of an insulating material or an antistatic material, which has more kinds of material colors than the conductive material, in consideration of the portions that can be seen from the back side of the mechanism plate 70. . Further, the stub base 77 and the stub cover 78 that are combined with each other are formed of materials having different surface resistance values (conductive material C and antistatic material A), so that the stub base 77 and the stub cover 78 flow down. The static electricity charged on the game ball B is positively attracted to the bell base 77 having a small surface resistance.

  As shown in FIG. 5, the upper plate 24 is formed by using an antistatic material A having a large surface resistance value so that the overhanging portion protruding from the front of the pachinko gaming machine 10 is used. Is formed using a conductive material A having a small surface resistance value. Further, the lower plate 25 is formed by using an antistatic material A having a large surface resistance so that the overhanging portion protruding from the front of the pachinko gaming machine 10 is provided, and the game ball B paid out beyond the capacity of the upper plate 24. Is formed using a conductive material A having a small surface resistance value.

  The manner in which the static electricity charged on the gaming ball B is removed in the payout path of the prize ball or the lending ball constituted by using the above-described materials will be described with reference to FIGS. FIG. 6 is an explanatory diagram schematically showing the rear side front of the mechanism plate 70. FIG. 7 is a graph showing the amount of static electricity removed from the start of ball lending to the end of ball lending for each region of the mechanism plate 70. FIG. 6 shows the mechanism plate 70 with the power supply / external terminal unit 80, power supply unit 81, firing control unit 82, main control unit 84, payout control unit 86, and bell tub cover 78 removed.

As shown in FIG. 6, the payout passages for the prize balls and the rental balls on the mechanism plate 70 are classified as follows from the passage upstream side according to the magnitude of the surface resistance value of the passages. Region surface resistance value is a conductive material A of 10 ⁰ Ω P (region from the sphere tank 72 to the tank rail 73), the area surface resistance value is a conductive material C of 10 ^3.8 Ω Q (case rails 74 regions), A region R made of a conductive material B having a surface resistance value of 10 ² Ω (a prize ball / ball rental unit 75 region) and a region S made of a conductive material C having a surface resistance value of 10 ^3.8 Ω (a Suzuki base 77 region) It is.

  In the pachinko gaming machine 10 before winning or lending a ball, gaming balls B are stored in the areas P, Q and R. When the game balls B stored in the respective regions P to R are charged with static electricity, the static electricity is removed to the outside as follows. First, in the area P, the static electricity of the game ball B in the ball tank 72 flows out of the ball tank 72 to the metal plate 90 via the convex portion 72a and the tank rail 73, and the static electricity of the game ball B in the tank rail 73 is discharged to the tank. It flows out from the rail 73 to the metal plate 90. The static electricity that has flowed out to the metal plate 90 in this way flows out to the mechanism plate hinges 71 and 79 through the bent portions 90a and 90b, and is removed outside the machine.

  Similarly, the static electricity of the game ball B in the case rail 74 in the region Q flows out of the case rail 74 to the metal plate 90, and flows out to the mechanism plate hinges 71, 79 through the bent portions 90a, 90b. It is removed outside. In addition, the static electricity of the game ball B in the prize ball / ball rental unit 75 in the region R flows out from the prize ball / ball rental unit 75 through the bell base 77 to the metal plate 90, and is bent. It is removed out of the machine by flowing out to the hinges 71, 79 for the mechanism plate through 90b.

  On the other hand, when a prize or ball lending occurs, the game balls B flow down in each of the regions P to S due to the start of the payout of the prize balls and the ball lending, and the ball supply device SE sends the ball B into the ball tank 72 or the tank rail 73. The game ball B falls inside. When a predetermined number of game balls B have been paid out, the payout of the prize balls and the rental balls ends, and the storage state of the game balls B in each of the regions P to R returns to a state substantially similar to that before winning or renting the balls. The static electricity generated in the areas P to R during the period from the start to the end of the payout of the prize ball or the lending ball flows out of the metal plate 90 to the hinges 71, 79 for the mechanism plate through the same route as described above, and the outside of the machine. Removed. In addition, the static electricity of the game balls B in the tub base 77 generated in the area S flows out of the tub base 77 to the metal plate 90, and flows out to the mechanism plate hinges 71, 79 through the bent portions 90a, 90b. Is removed outside the machine.

FIG. 7 shows the amount of static electricity removed in each of the areas P to S from the start to the end of the payout of the prize ball or the loaned ball, in the case of the loaned ball payout. As shown in FIG. 7, in the region P, the surface resistance value is small (10 ⁰ Ω) increases static electricity removal amount per unit time since. Therefore, in the area P, static electricity for the value e3 is removed from the start of ball lending to the end of ball lending.

On the other hand, in the regions Q and S, the surface resistance value is large ( ^103.8 Ω), and a large amount of static electricity is removed per unit time in the more upstream region P. Less. For this reason, in the area Q, static electricity for a value e1 smaller than the value e3 is removed from the start of ball lending to the end of ball lending.

Further, in the region R, as in the regions Q and S, a large amount of static electricity is removed per unit time in the region P on the more upstream side, so that the amount of static electricity removed per unit time is smaller than that in the region P. On the other hand, since the surface resistance value in the region R is smaller than the regions Q and S (10 ² Ω), the amount of static electricity removed per unit time is larger than that in the regions Q and S. Therefore, in the region R, static electricity corresponding to a value e2 smaller than the value e3 and larger than the value e1 is removed from the start of ball lending to the end of ball lending.

  As described above, by using the conductive materials A to C having different surface resistance values for the components constituting the payout path of the prize ball or the lending ball, the static electricity generated in the pachinko gaming machine 10 is quickly removed outside the machine. Is done. As a result, the static electricity charged in the pachinko gaming machine 10 at the time of paying out a prize ball or a lending ball is greatly reduced as compared with the related art. In the pachinko gaming machine 10 described above, in addition to the material change of each component constituting the payout path of the prize ball and the ball rental, the power supply / launch control board plate 83 on which various control boards are laid, A structure in which the plate 85, the dispensing control plate 87, and the lamp / sound plate 59 are connected to each other, and static electricity charged on the firing rail 30, the inner rail 49, the outer rail 51, and the like is discharged outside the machine. Adopt a configuration to remove. FIG. 8B shows the result of measuring the charging state during the game in such a pachinko gaming machine 10.

  FIG. 8 is a graph showing a potential difference generated in a pachinko gaming machine before and after paying out award balls and lending balls. In this graph, a change in the potential difference in the power supply line is sampled as data. The vertical axis indicates the potential difference, and the horizontal axis indicates the elapsed time. FIG. 8A shows a measurement result of the conventional pachinko gaming machine, and FIG. 8B shows a measurement result of the pachinko gaming machine 10 of the present embodiment. As shown in FIG. 8, before a prize ball or a lending ball is paid out, the potential difference in the power supply line is stable at around 5 volts.

  As can be seen by comparing FIG. 8 (A) and FIG. 8 (B), in the conventional pachinko gaming machine, when paying out award balls or lending balls, the maximum is 11 volts and the minimum is -2. A potential difference of volts is generated, and the width W2 at which the potential difference changes is 13 volts. On the other hand, in the pachinko gaming machine 10 of the present embodiment, when a prize ball or a rental ball is paid out, a potential difference of 6 volts at the maximum and 4 volts at the minimum occurs, and the width W1 at which the potential difference changes is 2 volts. It becomes. As described above, in the pachinko gaming machine 10 of the present embodiment, the width of the change in the potential difference of the power supply line at the time of paying out a prize ball or a lending ball is limited to about ± 1 volt, and is about 1/6 of the conventional pachinko gaming machine. Is reduced to From the above, it can be seen that in the pachinko gaming machine 10 of the present embodiment, static electricity is less likely to be charged in the pachinko gaming machine 10 when paying out prize balls or lending balls than in the conventional product.

  As shown in FIGS. 8A and 8B, in the pachinko gaming machine 10 of the present embodiment, after the payout is completed, the potential difference returns to the state before the payout earlier than in the conventional pachinko gaming machine. (In the case of the pachinko gaming machine 10 of this embodiment, the time t1 has elapsed since the end of payout, and in the case of the conventional pachinko gaming machine, the time t2 has elapsed since the end of payout). From the above, it can be seen that in the pachinko gaming machine 10 of the present embodiment, the static electricity generated with the start of the payout of the prize ball or the lending ball is quickly removed to the outside of the machine as compared with the conventional product.

  In the pachinko gaming machine 10 of the present embodiment described above, the ball tank 72, the tank rail 73, the case rail 74 and the prize ball / ball rental payout unit 75 are formed by using resin conductive materials having different surface resistance values. Then, the static electricity charged on the game ball B is removed from the ball tank 72, the tank rail 73, the case rail 74, the winning ball / ball rental payout unit 75 via the metal plate 90 to the outside of the machine. Accordingly, static electricity generated in the flow path of the game ball B reaching the prize ball / ball rental payout unit 75 can be effectively removed according to the difference in the surface resistance value. As a result, various controls such as the prize ball / ball rental sensors 75e and 75f provided in the prize ball / ball rental unit 75 and the payout control board and the main board provided near the prize ball / ball rental payout unit 75 are provided. Malfunction of the substrate can be reliably prevented.

  In the pachinko gaming machine 10 according to the present embodiment, the conductive material A having a smaller surface resistance value than the prize ball / ball rental payout unit 75 is used for the ball tank 72 and the tank rail 73. For this reason, static electricity generated by the flow of the game ball B at the time of ball lending or winning is positively removed in the ball tank 72 or the tank rail 73 upstream of the prize ball / ball lending payout unit 75. Therefore, the static electricity charged on the game ball B can be reliably removed before the game ball B reaches the prize ball / ball rental payout unit 75.

  In particular, when paying out a prize ball or a lending ball, the ball tank 72 and the ball rail 72 may collide due to the collision of the game balls B in the ball tank 72 or the friction between the flowing game ball B and the ball tank 72 and the tank rail 73. A large amount of static electricity is generated in the tank rail 73. According to the pachinko gaming machine 10 of the present embodiment, it is possible to immediately remove a large amount of static electricity generated in this way from the generation location to the outside of the machine, and to use the prize ball / ball-lending sensors 75e and 75f and various control boards. It is possible to further increase the certainty of preventing malfunction.

  Further, in the pachinko gaming machine 10 of the present embodiment, a rail connecting the ball tank 72 and the winning ball / ball rental payout unit 75 is configured by connecting a plurality of parts such as a tank rail 73 and a case rail 74 to each other. The rail 73 and the case rail 74 are formed using resin conductive materials having different surface resistance values. Therefore, static electricity on the rail can be more positively removed on the component side using the conductive material having a smaller surface resistance value. In this embodiment, since a conductive material having a smaller surface resistance value than the case rail 74 is used for the tank rail 73 disposed on the more upstream side, the static electricity charged on the game ball B is awarded to the prize ball / ball rental payout. It is positively removed at the tank rail 73 located on the more upstream side of the unit 75. Therefore, it is possible to reliably prevent the game balls B charged with static electricity from entering the prize ball / ball rental unit 75.

  In the present embodiment, the surface resistance of the conductive material used for each part of the ball tank 72, the tank rail 73, the case rail 74, and the prize ball / ball rental unit 75 is determined by the contact area between each part and the game ball. And a value corresponding to at least one of the presence or absence of the control component (prize ball / ball-lending sensor) in each part, and the magnitude of the collision frequency between the game balls in each part. In this way, the surface resistance value of the conductive material used for each part, the magnitude of friction between each part and the game ball at the time of ball lending and winning, the frequency of collision between game balls in each part, control The value depends on the degree of influence on the component. Therefore, the static electricity can be effectively removed according to the amount of static electricity generated in each part and the necessity of removing the static electricity. For example, since the conductive material A having a small surface resistance is used for the ball tank 72 and the tank rail 73 used at a point where a large amount of static electricity is generated due to friction and collision, a large amount of the material generated in the ball tank 72 and the tank rail 73 is used. The static electricity can be reliably removed from the ball tank 72 and the tank rail 73, and the charged game ball B flows to the downstream case rail 74 and the prize ball / ball rental unit 75. Can be suppressed.

  Further, in this embodiment, a metal plate 90 is provided as a connecting portion for electrically connecting the ball tank 72, the tank rail 73, the case rail 74, and the prize ball / ball rental unit 75, and the bent portion of the metal plate 90 is provided. 90a and 90b are electrically connected to hinges 71 and 79 for the mechanism plate. Accordingly, static electricity generated by the flow of the game ball B at the time of lending a ball or winning a prize is transferred from the ball tank 72, the tank rail 73, the case rail 74, the prize ball / ball rental unit 75 and the bell base 77 to the metal plate 90. It can be reliably removed outside the machine.

  In the present embodiment, the ball tank 72, the tank rail 73, the case rail 74, the prize ball / ball rental unit 75 and the suzuki base 77 are made of a conductive material. The upper plate 24 and the lower plate 25 to which the lending ball is supplied are formed using a conductive material A made of resin. Therefore, even after the prize ball or the lending ball is supplied to the upper plate 24 or the lower plate 25, the static electricity charged to the game ball B in the upper plate 24 or the lower plate 25 can be removed.

  Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and can be implemented in various modes without departing from the gist of the invention.

For example, in the above-described embodiment, the conductive material A having the same surface resistance value is used for the ball tank 72 and the tank rail 73, but the ball tank 72 and the tank rail 73 may be configured to use conductive materials having different surface resistance values. . For example, the spherical tank 72, using a conductive material smaller surface resistance than the conductive material used for the tank rails 73, the conductive material of the surface resistance of 10 ⁰ Omega a sphere tank 72, a surface resistance of 10 ¹ to the tank rail 73 A configuration in which a conductive material having a surface resistance of 10 ² Ω is used for the conductive material of Ω and the prize ball / ball rental unit 75 can be considered. Also in this configuration, the surface resistance of the ball tank 72 and the tank rail 73 is smaller than that of the ball lending unit 75, so that the static electricity charged on the game ball B is reliably removed upstream of the ball lending unit 75. It is possible to do. Further, the static electricity generated by the collision between the game balls B in the ball tank 72 can be quickly removed from the ball tank 72 through the metal plate 90 after the occurrence, and the static electricity can be efficiently removed from a point where the amount of generated static electricity is particularly large. Can be removed well.

  In the above embodiment, the tank rail 73, the case rail 74, and the bell base 77 are installed on the metal plate 90. However, the area of the metal plate 90 is expanded to the range where the ball tank 72 is mounted, A configuration in which the ball tank 72 is installed on the top 90 may be used. Further, it is also possible to adopt a configuration in which the prize ball / ball rental payout unit 75 is installed on the metal plate 90 without being installed in the bell basket base 77.

  Further, in the above-described embodiment, the conductive material is used for both the ball tank 72 and the tank rail 73. However, the conductive material may be used for only one of the ball tank 72 and the tank rail 73. For example, when a conductive material is used for the tank rail 73, static electricity generated in the ball tank 72 is drawn to the conductive tank rail 73 side and is removed outside the machine through the metal plate 90. Therefore, the static electricity charged on the game ball B can be positively removed on the upstream side of the prize ball / ball rental unit 75.
