2. Description of the Related Art As a ball-and-ball game machine represented by a pachinko machine, a game board and a launching device are configured to be held in an upright state by a front frame having a ball plate at a lower portion, and a back surface of the front frame. On the side, there is provided a back mechanism that stores a large number of prize balls and performs a process of paying out a predetermined number of prize balls to a ball plate when a game ball fired from the launch device wins a prize device. Things are generally known. In the past, such components of pachinko machines have often been made from wood, metal materials, etc., but recently, they are easy to manufacture and process, can cope with complex shapes, reduce weight and reduce noise. Resin-made components that can be used are increasingly used.

In a more recent pachinko machine, a control device for detecting a prize of a game ball and paying out a prize ball corresponding thereto is digitized to electrically detect the presence or absence of a prize and to detect the detection signal. On the basis of the above, control of blinking of a lamp in the game area, various symbol display controls on the liquid crystal display device, control of a prize ball payout process, and the like are performed. Therefore, the back mechanism is provided with a control board on which a number of electronic components such as a CPU, a RAM, and a ROM are mounted in order to perform such various controls.

[0004]

In a pachinko machine (ball game machine) having such a configuration, as described above, the components of the back mechanism (particularly, the components that directly contact the prize ball) are made of a resin material. In such a case, since the metal prize ball is moved in the back mechanism while being in contact with the resin component and is paid out to the ball tray, static electricity is easily generated by the contact with the metal prize ball. When the static electricity accumulates in the resin component and discharges, the electronic component on the substrate provided on the back mechanism is adversely affected, and the lamp blinking control, the symbol display control, and the prize ball payout process described above. There is a problem that control may be inaccurate or malfunction may occur.

[0005] In order to avoid such a problem, it is conceivable that a component part in contact with the metal prize ball in the back mechanism is made of metal. However, when a metal material is used, there is a problem in that it is difficult to process and manufacture a complicated part, there is a high possibility that the weight will increase, and there is a problem that noise when contacting a prize ball increases. For this reason, it is required that the pachinko machine be configured using resin components as much as possible.

The present invention has been made in view of such circumstances.
In a ball-and-ball game machine, it is an object to constitute a back mechanism and make a member that directly contacts a prize ball from a resin material, and to prevent generation of static electricity due to contact with the prize ball.

Further, since the metal layer is formed on the surface of the ball contact member made of the resin material, it is possible to suppress the generation of static electricity when the ball contacts the metal prize ball. For this reason, it is possible to prevent an adverse effect of static electricity on the electronic components on the substrate provided in the back mechanism, and to control the lamp blinking, the symbol display control, and the prize ball payout processing control by the electronic components accurately and without malfunction. be able to.

Preferably, the metal layer formed on the surface of the resin material is formed of the same material as the surface metal layer of the prize ball. Generally, prize balls (game balls) used in pachinko machines are made by applying chrome plating to the surface of a steel ball. In this case, the ball contact member is provided with chrome plating on the surface of a resin molded product. It is made by being applied. As a result, it is possible to further prevent static electricity from being generated due to contact between the prize ball and the metal layer.

I have.

On the other hand, as shown in FIG. 4, the ball dispensing / discharging mechanism 40 has a single opening / closing base frame 41 (a ball storage / supply mechanism) which forms a left / right side-opening board body. 20), a collective discharge path 42 of the played balls (safe ball and out-ball), a prize ball discharge path 43 of the discharged prize balls to the ball plate side, and a transmission from the ball storage and supply mechanism 20. The ball storage and supply mechanism 20 is equipped with a prize ball passage route 44 and a ball payout unit 45, related mechanisms and members, respectively.
Is configured as a unitized set member. The whole set member can be opened left and right by the hinge 46 and is supported on the back side of the front frame 2, and is locked and held on the front frame 2 by the closing lever 47 in a closed state covering the back surface of the front frame 2. It has become.

The collective discharge path 42 communicates with a ball receiving chamber 48a defined in the upper part and a ball passage 48b opened at the lower part of the ball receiving chamber 48a. The out ball transferred from the out port 16 and the safe ball transferred from each winning tool are received in the ball receiving chamber 48a, and can be finally discharged from the lower end exit of the collecting path 42 to the back of the machine. ing.

On the other hand, the prize ball discharge path 43 is a prize ball path 43a partitioned from the upper portion on the outside (rear side) to the lower portion.
And the upper ball exit 4 which is opened and communicated above the prize ball path 43a.
3b and a lower ball exit 43 opened at the lower end of the prize ball path 43a.
c. In the prize ball discharge path 43, the prize balls paid out from the ball payout section 45 are discharged from above the prize ball path 43a to the upper ball plate 7a via the upper ball exit 43b. Further, surplus prize balls overflowing from the vicinity of the upper ball exit 43b are discharged to the lower ball outlet 43c of the prize ball path 43a via the bypass, and are discharged to the lower ball plate 7b side. The prize ball discharge path 43 includes a ball detection lever 49a attached near the lower ball exit 43c and a switch 49b pushed by the lever 49a. The state of charge can be detected.

In the ball dispensing mechanism 40 of the back mechanism BM having the above-described structure, the ball dispensing mechanism 40 is operated on the open / close base frame 41 by receiving the power supply from the terminal control unit 23 and disposed on the front surface of the game board 10. Control boards for controlling the lighting of the lamps, controlling the display of the liquid crystal symbol display device, controlling the payout of prize balls, and the like are attached. For ease of explanation, these control boards are attached in FIG. This shows the previous state. In addition, these control boards have a CP on the board.
Various electronic components such as U, RAM, ROM and the like are mounted.

In the pachinko machine PM configured as described above, most of the components or members constituting the back mechanism BM are made of a molded product of a resin material such as plastic. In particular, a prize ball B (also called a game ball or a pachinko ball)
, A member that constitutes a path for guiding the prize ball B, for example, an alignment gutter member 22, a collective discharge path 4
2. Parts or members that come into contact with the prize ball B, such as a prize ball discharge path 43, a prize ball entrance path 44, a ball receiving chamber 48a, a ball port 48b, a foul ball discharge path (not shown), etc. Contact member) is made of a resin molded product.

By forming a resin molded product in this way,
Compared to the case where it is made by processing a metal plate material, it is possible to reduce the weight, to easily form into a complicated shape, and to reduce the noise when the prize ball abuts and contacts and moves. I have. By the way, the prize ball B is made by applying chrome plating to the surface of a steel ball. When such a metal prize ball B moves while contacting a ball contact member made of resin, static electricity is generated. In addition, static electricity easily accumulates in the resin ball contact member. If the potential is increased due to accumulation of static electricity as described above, this may be discharged and adversely affect the electronic components on the control board constituting the back mechanism BM.

From the above, the resin members (in particular, the alignment gutter member 22, the collective discharge path 42, the prize ball discharge path 43, the prize ball passage path 44, the ball receiving chamber 48a, and the ball port 4)
8b, a ball contact member such as a not-shown ball discharge path) is formed by applying chrome plating to the surface of a resin molded product. The chrome plating is referred to as decorative chrome plating and the like, and is a plating provided on the surface of a metal material or a plastic material, and is generally well known. Is omitted.

As described above, even if the prize ball B comes into contact with and moves on the resin member (ball contact member) whose surface is chrome-plated, the surface of the prize ball B is also chrome-plated. Therefore, the generation of static electricity is prevented, and the accumulation of static electricity in the resin member can be prevented. For this reason, the electronic components on the control board are not adversely affected by the discharge of the static electricity.

As can be seen from the above, it is preferable to apply chrome plating to at least the portion of the resin member (ball contact member) that contacts the winning ball B. The plating applied to the surface of the resin member is most preferably the same as the plating material on the surface of the prize ball B, but may be a different metal plating.

If the surface of the resin member is plated with metal as described above, the generation of static electricity due to the contact with the prize ball B can be suppressed. However, there is still a possibility that static electricity may be slightly generated. It is more preferable that the metal plating portion on the surface of the resin member is connected to, for example, the ground terminal of the terminal control unit 23 so as to be grounded.
By doing so, it is possible not only to reliably prevent static electricity from being generated on the ball contacting member, but also when the game ball comes into contact with the ball contacting member when the game ball is charged with static electricity outside the gaming machine. The static electricity of the game ball can be removed.

[0028]

As described above, according to the present invention,
Since the sphere contact member that contacts the prize ball during the processing of storing and dispensing the prize ball is made of a resin material, the material constituting the back mechanism is easy to work, the weight can be reduced, and the contact with the prize ball can be achieved. Noise can be reduced. Furthermore, since the metal layer is formed on the surface of the ball contact member made of a resin material, it is possible to suppress the generation of static electricity when contacting the metal prize ball, and to prevent the occurrence of static electricity on the substrate provided on the back mechanism. The electronic components can be prevented from being adversely affected by the discharge of static electricity, and the lamp blinking control, the symbol display control, and the prize ball payout process control by the electronic components can be performed accurately and without malfunction.

The metal layer formed on the surface of the resin material is preferably formed of the same material as the surface metal layer of the prize ball. Generally, prize balls (game balls) used in pachinko machines are made by applying chrome plating to the surface of a steel ball. In this case, the ball contact member is provided with chrome plating on the surface of a resin molded product. It is made by being applied. This can reliably prevent static electricity from being generated by contact between the prize ball and the metal layer.

A ball storage and supply mechanism for storing and holding a prize ball and aligning and supplying the stored prize balls, and a prize ball for a game ball for aligning and supplying the prize balls supplied from the ball storage and supply mechanism. Is often configured to have a ball payout mechanism for paying out to a ball plate in accordance with a prize. In this case, a member for storing and holding a prize ball and a supply path for supplying a prize ball in the ball storage and supply mechanism A member constituting
The member forming the passage for paying out the prize ball in the ball payout mechanism corresponds to the ball contact member, and is made of a resin having a metal layer formed on the surface. Further, the ball dish may be made of a resin having a metal layer formed on the surface.

In any case, it is preferable to connect the metal layer formed on the surface of the resin constituting the ball contact member to ground. This can reliably prevent static electricity from being generated on the ball contact member, and when the game ball contacts the ball contact member when the game ball is charged with static electricity outside the gaming machine, It can also remove static electricity.
