The number is supplied to the upper plate 3A of the pachinko gaming table 3 provided with the ball rental machine 2, and the pachinko gaming on the pachinko gaming table 3 becomes possible.

As a result of the pachinko game at the pachinko gaming table 3, when a prize is won, a predetermined number of pachinko balls 9 flow down from the upper tank 1 and are paid back to the upper plate 3A of the pachinko gaming table 3. Pachinko balls hit are 3
And flows down through the lower hole 3B and is collected in the lower tank 5.

Further, the pachinko balls 9 overflowing from the upper plate 3A of the pachinko gaming table 3 are received by the lower plate 3C. The lower plate 3C is provided with a bottom lid that can be opened and closed by a lever 3D, and communicates with the ball box 4 immediately below.

When the bottom of the carton box 4 is opened, the pachinko balls 9 accumulated in the carton box 4 are counted by a counting device (not shown), and thereafter flow down to the lower tank 5 to be collected. The counting result is recorded on a card (not shown) or the like,
Issued to the person who played the game.

The pachinko balls collected in the lower tank 5 are:
The liquid is lifted in the lifting pipe 6 by the lifting device 7, its surface is polished by the polishing device 8, and then transferred to the upper tank 1.

The lower tank 5 is a box-shaped lower tank body 1
An inclined cover 13 made of a transparent material such as, for example, polycarbonate is provided so as to cover the entire upper surface of 1. The slant of the slant cover 13 is for the pachinko balls to flow down along the slant. The cross-sectional shape of the inclined cover 13 perpendicular to the flowing direction is a waveform 15. This waveform is supported at two points between adjacent tops so that the pachinko balls 9 do not touch the bottom. Further, both ends of the cross section of the inclined cover 13 form a rising 17.

At the lower end of the inclined cover 13 in the downward direction,
A plate 21 having a round drop port 19 having a diameter to which the pachinko ball 9 can drop is connected. A slit 23 is formed between the inclined cover 13 and the plate 21. The slit 23 traverses the flowing direction of the pachinko ball 9 and has a dimension 2 of approximately half (30% to 70%) the diameter of the pachinko ball 9.
5 A dust container 27 for receiving dust and foreign matters is provided on the lower surface of the slit 23. Dust container 2
Reference numeral 7 is long along the slit 23 and has a U-shaped cross section perpendicular to the longitudinal direction, and flanges 29 are formed at both ends of the U-shape. Both flanges are supported by a supporting tongue 31 provided on the inclined cover 13 side, and thus the dust container 2
7 is detachable by its movement in the longitudinal direction.

Below the plate 21 having the round drop port 19, a receiving ramp 33 for receiving the falling pachinko balls 9 is provided.
The plate 35 is provided at an angle. The inclination of the receiving inclined table 33 and the sloped plate 35 is opposite to the inclination of the inclined cover 13. A substantially funnel-shaped receiving portion 37 is provided at the end of the scalloped plate 35. The receiving portion 37 is inclined toward the center hole 39, and a gutter 41 is provided below the hole 39, and is connected to the lifting device 7.

(Operation of the Embodiment) The pachinko balls 9 flowing down from the ball box 4 are received on the inclined cover 13 and flow down along the inclination of the inclined cover 13. At this time, the pachinko balls 9 are supported at two points between the adjacent tops of the inclined cover 13. On the other hand, fine foreign matters and dust that have fallen onto the inclined cover 13 from above accumulate at the bottom of the waveform. Therefore, the pachinko balls 9 hardly touch the accumulated dust and foreign matter.

Further, as the pachinko ball 9 flows down, the inclined cover 13 and the like vibrate, and due to such vibrations, foreign matter and dust flow down the bottom of the waveform. Eventually, foreign matter and dust
It falls from the slit 23 formed between the inclined cover 13 and the plate 21 and is collected by the dust container 27. The pachinko ball 9 passes over the slit 23.

Then, the pachinko balls 9 fall downward from the drop openings 19 of the plate 21. And the receiving ramp 3
3, passes over the saw-shaped plate 35, is received by the substantially funnel-shaped receiving portion 37, falls into the central hole 39, passes through the gutter 41, and is sent to the lifting device 7.

(Effects of the Embodiment) According to the above-described embodiment, by providing the inclined cover 13 on the entire upper surface as compared with the case where the upper surface of the lower tank 5 is opened, foreign matter falling from above can be prevented. It can be prevented from getting inside. Furthermore, by forming the cross-sectional shape of the inclined cover 13 into a waveform, and further forming this waveform so that the pachinko balls 9 are supported at two points on the adjacent top side so that the pachinko balls 9 do not touch the bottom of the waveform, finer shapes are obtained. Foreign matter and dust can accumulate at the bottom of the waveform and hardly accumulate at the top. Therefore, it is possible to make the pachinko balls less likely to be stained.

In addition, foreign substances and dust that similarly flow down the bottom of the waveform due to vibrations caused by the flow of the pachinko balls 9 are reduced by the slits 2 formed between the inclined cover 13 and the plate 21.
3 and is received by the dust container 27. Therefore,
Dust and foreign matter are prevented from falling into the lower tank 5, and the pachinko balls 9 inside are less likely to become dirty.
