Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a mechanical board of a pachinko machine which is rotatably mounted on the back surface of a game board and includes various back parts.

[Conventional technology]

FIG. 3 is a rear view of a pachinko machine equipped with a conventional mechanical plate as described above. The mechanical plate 1 is made of a synthetic resin material such as plastic. More specifically, the mechanism plate 1 has a plate-shaped portion 1a facing the back surface of the game board 2, and the winning ball collecting portion 3 is formed in the lower front portion of the plate-shaped portion 1a. The prize ball tank 4 is fixed to the upper portion of the back surface of the plate-shaped portion 1a. Below the prize ball tank 4, a guide trough 6a for aligning the prize balls and guiding them to the prize ball case 5 is formed. Below the prize ball case 5, a prize ball discharge trough 6b for guiding the prize ball discharged from the prize ball case 5 to a ball tray (not shown) in front of the machine is formed. At the exit of the winning ball collecting section 3, there is formed a winning ball lead-out path 7 for guiding the winning balls in one row,
A ball receiving rack 8 is formed at the lower end of the flow. The right side of the ball receiving rack 8 is opened to form a winning ball discharging section 9, and below the discharging section 9, the winning ball discharging path 10 for discharging the winning ball out of the machine.
Are formed. On the left side of the ball receiving rack 8, a winning ball discharge processing device 11 is provided.

As shown in FIG. 4, the winning ball discharge processing device 11 includes an electric drive source, for example, a motor 12, a cam 14 fixed to an output shaft 13 of the motor 12, and a lower end of which can be rocked by a shaft 15. The ball feeding member 16 supported by the rocking member 17 and a rocking member 17 and a locking member 18 which are located on the side of the discharging portion 9 and are opposed to the ball feeding member 16 are generally configured. The ball feeding member 16 is
It has a horizontal arm 16b integrally provided with a roller 16a for engaging and disengaging the blade 14a of the cam 14 at the upper end, and the tension spring 19 keeps the roller 1b constantly.
6a and cam 14 are kept in contact with each other. Also the swinging member
17 has a shaft 20 that is swingably supported near the upper end.
It has a ball contact part 17a that hangs downward and faces the discharge part 9 and an arm part 17b that projects in the lateral direction. The arm part 17b and the operating lever 21 of the prize ball case 5 are connected by a vertical rod 22. There is. One end of the locking member 18 is pivotally supported by a shaft 33, and the locking member 18 engages with the upper end of the rocking member 17 to restrain the rocking.
It has an upper arm 18b formed with a lower arm 18c and a lower arm 18c which faces the ball receiving rack 8 from the discharging portion 9.

The winning ball discharge processing device 11 is, for example, the actual exploitation Sho 59-87886.
The operation is as follows. The winning balls collected in the winning ball collecting unit 3 flow down the winning ball outflow path 7 and are received on the upper surface of the ball receiving rack 8. At this time, the locking member 18 is swung by the winning ball contacting the lower arm 18c and is swung by the step portion 18a as shown by the solid line in FIG.
Release the restraint of 7. On the other hand, by driving the motor 12, the cam 1
4 rotates in the direction of the arrow, and the blade 14a rotates the roller of the ball feeding member 16.
By engaging with 16a, the ball feeding member 16 swings against the tension spring 19 as shown by the chain line in FIG. By this, the ball feeding member
The horizontal arms 16b of 16 plunge into the winning ball deriving path 7 and push out the winning balls located on the upper surface of the ball receiving rack 8 to the discharging portion 9. The winning ball extruded to the discharging portion 9 contacts the ball contact portion 17a of the rocking member 17 while rocking the locking member 18 as shown by the chain line in FIG. It falls into the discharge path 10 and is discharged to the outside of the machine. Then, the vertical rod 22 is raised by the swing of the swinging member 17, and the operating lever 21 of the prize ball case 5 is pivoted upward as shown by the chain line in FIG. The operation is performed to discharge the gift balls inside the ball to the gift ball discharge gutter 6b.

[Problems to be solved by the device]

By the way, as described above, the mechanism plate 1 is usually formed of a synthetic resin in order to reduce the overall weight of the pachinko machine and enable mass production of the mechanism plate 1. On the other hand, in the mechanism plate 1 provided with the winning ball discharge processing device 11 as shown in FIG. 4, since the ball receiving rack 8 is made of synthetic resin, the friction resistance of the upper surface of the ball receiving rack 8 is large. As a result, the prize-winning ball slips poorly and an extra load is applied to the ball feeding member 16. In addition, thousands of winning balls are received on the upper surface of the ball receiving rack 8 per day, and the winning balls are received by the ball feed member 16.
It has been found that there is a problem in that the upper surface of the ball receiving rack 8 is easily worn and the winning ball cannot be smoothly discharged because the upper surface of the ball receiving rack 8 is forcibly discharged while being in contact with the upper surface.

The present invention was created in view of the above circumstances.

[Means for Solving the Problems]

The present invention comprises a metal piece on the upper surface of the ball receiving rack 8 for receiving the winning balls.
It is the one that wears 23.

[Action]

In the case of such a configuration, the winning ball received on the upper surface of the ball receiving rack 8 slides smoothly, and the ball feeding member 16
The load on the ball is reduced, and the upper surface of the ball receiving rack 8 is prevented from being worn, so that a smooth discharging operation of the winning ball can be expected.

〔Example〕

FIG. 1 is a perspective view of the winning ball discharge processing device 11 portion, in which a metal piece 23 is attached to the upper surface of the ball receiving rack 8. The metal piece 23
As shown in FIG. 2 (a), the attachment piece portions 23a and 23b protruding on the rear side and the right side are bent as shown, and the engaging piece portion 23c protruding on the front side is formed. It is attached by engaging with an engaging portion 24 formed in the plate-shaped portion 1a of the mechanism plate 1. Then, the attaching piece 23a is covered with the cover plate 25 that covers the rear surface of the prize ball discharge processing device 11.
Is pressed to prevent the metal piece 23 from falling off. still,
It is also conceivable to form the whole or a part of the ball receiving rack 8 with the metal piece 23 as shown in FIG. by this,
The ball receiving rack 8 becomes strong, and the ball receiving rack 8 can have strength enough to withstand the load of the winning balls lined up continuously in the winning ball lead-out path 7.

[Effect of device]

As described above, according to the present invention, the metal piece adhered to the upper surface of the ball receiving rack allows the winning ball to slide smoothly, and the load on the ball feeding member is significantly reduced. Further, the upper surface of the ball receiving rack is prevented from being worn, and the winning ball can be smoothly discharged over a long period of time. Further, the strength of the ball receiving shelf portion can be remarkably increased.
