Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko ball passage disposed at a predetermined position of a pachinko game machine, wherein the pachinko ball allows a small amount of dust to be stored in the pachinko ball passage so that the pachinko ball flows smoothly. The present invention relates to a pachinko gaming machine that is secured.

[0002]

2. Description of the Related Art A conventional pachinko game machine is provided with a tank rail, a curve rail, a supply passage in a ball payout device, and a game rail mounted on the back of a game board for supplying pachinko balls in a ball tank to a ball payout device. A prize ball collecting gutter disposed below the prize ball collecting cover that covers the back surface of the game board and receiving a prize ball led out to the back side of the game board, a prize ball connected to the prize ball collecting gutter and forming a prize ball into a prize ball processing device or a pachinko game machine. A number of pachinko ball passages, such as a winning ball discharge passage for discharging to the outside, are provided at each predetermined position. By the way, it is better that dust does not enter these pachinko ball passages in order to ensure a smooth flow of the pachinko ball, but the dust easily adheres to the surface of the pachinko ball due to static electricity. The upper surface is open, and it is relatively easy for dust to enter. Therefore, for example, in the case of the tank rail, as shown in FIG.
A discharge groove 103 for removing dust is formed along one side edge R of the bottom wall 102 of each of the ball passages 101. Also,
Japanese Patent No. 2698876 discloses a curve rail.
That is, as shown in FIG. 20, a step portion 108 having a low downstream side is provided on a bottom wall 107 which is located on the downstream side of the curve rail 104, is slightly upstream from the ball entrance 106 to the ball payout device 105, and is inclined downward. The bottom wall 107a of the step 108,
A vertical discharge groove 109 for removing dust is formed between 107b.

[0003]

However, in the former tank rail 100, since the discharge groove 103 is provided only on one side edge R of the bottom wall 102 of the ball passage 101, the bottom wall 102 is not provided. The dust is almost left as it is and accumulates on the other side edge L of the upper surface. Further, in the latter curve rail 104, the bottom wall 107b on the downstream side of the step portion 108 is also inclined downward toward the downstream similarly to the bottom wall 107a on the upstream side, and the discharge groove 109 is opened vertically. Therefore, if the upper surface of the upstream bottom wall 107a is temporarily
The dust falling below is received on the upper surface of the bottom wall 107b on the downstream side as it is, and is hardly discharged to the outside from the discharge groove 109. As described above, the dust-removing effect has not been sufficiently exerted in spite of the adoption of the dust-removing structure. Therefore, when the dust accumulates in this way, the dust spreads not only in the tank rail 100 and the curve rail 104 but also in the other pachinko ball passages, not only preventing the smooth flow of the pachinko ball but also causing one of the ball jams. Had become. Furthermore, since dirt adheres to the surface of the pachinko ball and moves widely, it also adheres to other devices such as a ball dispensing device, and these devices may malfunction and cause a malfunction. Also occurs.

Accordingly, the present invention has been made in view of the above-mentioned problems, and an object of the present invention is to secure a smooth flow of pachinko balls by hardly collecting dust in a ball passage of a pachinko ball passage portion. And a pachinko game machine.

[0005]

In order to achieve the above object, the present invention provides a pachinko ball passage disposed at a predetermined position of a pachinko game machine, wherein the pachinko ball passage is provided at a bottom wall thereof. A configuration is made in which discharge grooves for removing dust are alternately provided on one side and the other side along the side edges. The pachinko ball passage includes a tank rail, a winning ball collecting gutter, and the like.In this manner, the discharge grooves are alternately formed on one side and the other side on both side edges of the bottom wall of the ball passage in the pachinko ball passage. By opening the doors at different positions, the dust hardly accumulates on both side edges, which are corners where dust easily accumulates, thereby ensuring a smooth flow of pachinko balls.

As another solution, there is provided a pachinko ball passage disposed at a predetermined position of a pachinko game machine, and a dust removing device along a longitudinal direction of a bottom wall of the ball passage of the pachinko ball passage. And the bottom wall may have an upper surface inclined downward toward the discharge groove. In this case, it is not necessary to provide the discharge groove on both side edges of the ball passage. By inclining the bottom wall in this way, dust on the upper surface moves downward and easily falls from the discharge groove.

As another solution, there is provided a pachinko ball passage provided at a predetermined position of the pachinko game machine, wherein the ball passage of the pachinko ball passage has a step recessed on the downstream side. It is also possible to adopt a configuration in which a discharge groove for removing dust is opened at an appropriate position in the ball passage in association with the above. In this case, a drop is generated on the bottom wall by the step, so that the impact of the pachinko ball when the step falls is propagated as vibration to the pachinko ball and other pachinko spheres, thereby adhering to the pachinko ball. The garbage that has fallen is dropped, and the garbage is discharged from a discharge groove formed at an appropriate position in the ball passage in association with the step portion.

[0008] For example, as a means for solving the problem, a pachinko ball passage disposed at a predetermined position of a pachinko gaming machine,
The pachinko ball passage portion has a configuration in which a stepped portion on the downstream side is formed in the bottom wall of the ball passage in a transverse shape and a discharge groove for removing dust along the stepped portion is formed on the bottom wall directly below the stepped portion. preferable. By providing a step in this way, impacts are given and dust attached to the pachinko balls fall off well, and the impact is also propagated to the pachinko balls on the upstream side, causing ball breaking and preventing ball clogging As a result, a smooth flow of the pachinko balls is ensured.

Similarly, in a pachinko ball passage disposed at a predetermined position of the pachinko gaming machine, a discharge groove for dust removal is opened in a side wall of the ball passage of the pachinko ball passage, and the side wall is located upstream. A configuration may be employed in which the ball passage is inclined so that the lateral width of the ball passage gradually increases toward the discharge groove on the side. In this way, even if the discharge groove is opened on the side wall, the dust removal effect is exhibited,
In addition, the inclination of the side wall as described above causes the ball to be broken, which also ensures the smooth flow of the ball.

Further, as another solution, there is provided a pachinko ball passage portion which is disposed at a predetermined position of the pachinko game machine and has a stepped portion which is recessed on the bottom wall of the ball passage at a connection portion thereof. It is also possible to adopt a configuration in which it is formed in a transverse shape, and a discharge groove for removing dust is opened along the step on the bottom wall just below the step. This case is applied to, for example, a connection portion between a tank rail and a curve rail.

As another solution, there is provided a pachinko ball passage portion which is disposed at a predetermined position of the pachinko gaming machine and has a gap at a connection portion thereof and has a lower end edge of the upstream ball passage and a downstream end thereof. A configuration may be adopted in which a discharge groove for removing dust is opened between the upper end of the ball passage on the side.

For example, as a solution to this problem, two continuous pachinko ball passages are provided at predetermined positions of a pachinko game machine, and a gap is provided at a connection portion between the pachinko ball passages and a lower end edge of the upstream ball passage and a downstream side. A discharge groove for dust removal is opened between the upper end of the ball path and the lower end of the bottom wall of the ball path on the upstream side. Preferably, the side wall of the passage portion is inclined so that the lateral width of the spherical passage gradually increases toward the upstream discharge groove.

Further, a pachinko ball passage disposed at a predetermined position of the pachinko gaming machine and bent substantially horizontally from a downstream end, wherein a discharge groove for removing dust is formed in the ball passage at the bent portion, for example, a bottom wall. It is good also as composition. This case is applied to, for example, a supply passage of a ball payout device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a pachinko game machine according to the present invention will be described below with reference to the drawings. FIG. 1 is a rear view of the pachinko gaming machine according to the present invention. In the figure,
1 is a machine frame of a pachinko game machine, 2 is a front frame which is openably and closably mounted on a front surface thereof, 3 is a game board which is detachably mounted on the back surface of the front frame 2, and 4 is a game board which can be opened and closed on the back surface of the game board 3. This is a mechanism plate made of a synthetic resin mounted. An opening window 5 is formed in the mechanism plate 4 so as to correspond to the back surface of the game board 3. Further, the game board 3 is positioned between the game board 3 and the mechanism board 4 so as to match the opening window 5. 3 is provided with a winning ball set cover 6 covering the back surface. Further, below the prize ball collecting cover 6, there is provided a prize ball collecting gutter 7 as a pachinko ball passage portion for collecting prize balls guided to the back side of the game board 3, and further, a prize ball connected to the prize ball collecting gutter 7 is provided. A discharge passage 8 is provided, and a winning ball processing device 9 is mounted at the end thereof. The pachinko balls guided to the back side of the gaming board 3 are gathered in a winning ball collecting gutter 7 and guided to a winning ball processing device 9 via a winning ball discharging passage 8 for processing. It is discharged outside. In the case of a pachinko gaming machine without the winning ball processing device 9, the game is directly discharged to the outside.

A ball tank 10 is provided on the upper rear surface of the mechanism plate 4.
Is provided. Below the ball tank 10, a tank rail 11 is provided as a pachinko ball passage for guiding the pachinko balls of the ball tank 10 in a line, and a downstream side of the tank rail 11 is provided as a pachinko ball passage. Is connected to a ball payout device 13 through a curved rail 12.
The pachinko balls stored in the ball tank 10 flow down the ball passages of the tank rail 11 and the curve rail 12 and are continuously supplied to the ball payout device 13 while being aligned. The pachinko balls dispensed from the ball dispensing device 13 are guided to the front side of the pachinko game machine through a ball discharge passage 14 therebelow.

Therefore, for example, the tank rail 11
As shown in FIG. 2 to FIG. 4, the rear wall 15 which is in contact with the mechanism plate 4 with the synthetic resin, the bottom wall 16 which is inclined downward to the curve rail 12 side, and the front wall 17 are formed in a gutter shape having an open upper surface. In addition, the bottom wall 16 is provided with two partition walls 18 in the longitudinal direction to form three ball passages 19. On the upstream side of the front wall 17, the upper half bulges forward in an arc shape, and an auxiliary sphere passage 20 connected to the sphere passage 19 is formed substantially parallel to the sphere passage 19 inside the upper half. By providing the auxiliary ball passage 20 in this manner, the ball tank 1
Pachinko balls discharged from 0 to the tank rail 11 are prevented from spilling. The downstream edges of the front and rear side walls 15, 17 and the partition wall 18 are inclined toward the upstream side, and the height h of the downstream end portion of the front side wall 17 is selected to be at least twice the diameter of the pachinko ball. . Further, the partition wall 18 is formed so as to gradually increase from the upstream side to the downstream side, and the height h1 of the downstream end portion is selected to be substantially the same as or slightly lower than the diameter of the pachinko ball.

The bottom wall 16 of each of the ball passages 19 has, at both side edges thereof, discharge grooves 21 for removing dust along its longitudinal direction so that the positions thereof are alternately changed between one side and the other side. Has been established. More specifically, each of the discharge grooves 21 is formed in a vertically long shape having an appropriate length, and the front end in the longitudinal direction is located at the same position as the rear end of the discharge groove 21 on the other side. The width of each discharge groove 21 is set to be slightly shorter than half the width of the bottom wall 16 of each ball passage 19. As a result, the pachinko balls smoothly flow down the respective ball passages 19 so as to be in contact with the substantially center line of the bottom wall 16 thereof. In addition, each discharge groove 21 on the downstream side is replaced with another discharge groove 21.
It is formed longer. Reinforcing ribs 22 are provided on the back surface of the bottom wall 16 at substantially regular intervals, except for the portion of the discharge groove 21, in a transverse and integral manner.

The curve rail 12 has three ball passages 23 like the tank rail 11, and each of the ball passages 23 has a peripheral side wall surrounded by a wall. The upstream side is formed as a straight introduction ball passage portion 121 communicating with each ball passage 19 of the tank rail 11, and the downstream side is formed as a meandering bent ball passage portion 122. The upstream side of the introduction ball passage portion 121 is provided so that the upper wall 24 gradually widens toward the upstream side, so that ball clogging does not occur in the vicinity thereof.

In the pachinko gaming machine according to the present invention, a discharge groove 21 for removing dust is formed on the bottom wall 16 of the ball passage 19 of the tank rail 11, which is the pachinko ball passage, along both side edges thereof. Since the positions are alternately provided on the side and the other side, dust can be dropped through the discharge groove 21 and discharged to the outside from any side edge portion where dust is relatively easily accumulated. In addition, since the bottom wall 16 upper surface is inclined in the side edge portion of the portion on the other side of the discharge groove 21 where the discharge groove 21 is not provided, the pachinko ball flows down.
The garbage moves to the downstream side, and the discharge channel 2 on the downstream side of that side
1 will fall downward. This almost eliminates the accumulation of dust in the ball passage 19,
A smooth flow of pachinko balls is ensured. In addition, since the dirt on the pachinko balls is reduced, malfunction of other devices such as a ball dispensing device caused by the movement of dust is also prevented.

The auxiliary sphere passage 20 has a discharge groove 21 for removing dust along the front edge of the bottom wall 16 as shown in FIGS.
The upper surface thereof is inclined downward toward the discharge groove 21 so that dust can easily fall. Further, since the pachinko ball in the auxiliary ball passage 20 is subjected to the ball pressure on the outside and the ball pressure is not much applied to the pachinko ball in the ball passage 19, the auxiliary ball passage 20 and the ball passage 1
The spheres do not concentrate even at the junction with the sphere 9, and the spheres are hardly clogged. In addition,
Although not shown, the discharge groove 21 may not be formed in the bottom wall 16 and the upper surface of the bottom wall 16 may be inclined downward toward the spherical passage 19.

FIG. 5A is a side sectional view of a tank rail according to another embodiment.
a, a discharge groove 21a is formed in the center of the bottom wall 16a of each ball passage 19a along the longitudinal direction thereof, and the upper surface of both bottom walls 16a sandwiching the discharge groove 21a is the discharge groove 21a.
It is inclined downward toward a. By doing so, the dust on the upper surfaces of both bottom walls 16a can easily move toward the discharge groove 21a, and the dust removing effect is sufficiently exhibited.

FIG. 5B is a side sectional view of a tank rail according to another embodiment.
b, a discharge groove 21b is formed in one side edge of the bottom wall 16b of each ball passage 19b along the longitudinal direction thereof. Even in this case, the dust removing effect is sufficiently exerted as described above. In addition, since the upper surface of the bottom wall 16b is inclined as described above, the pressure of the pachinko balls is dispersed and the balls are broken, thereby ensuring a smooth flow of the pachinko balls. In particular, it is more effective in a wide ball passage in which pachinko balls flow simultaneously in two or three rows.

FIGS. 6 to 8 also relate to another embodiment. In this tank rail 11c, a stepped portion 25 whose downstream side is recessed in the bottom wall 16c over the three ball passages 19c.
Are formed transversely, and the bottom wall 16 directly below each step 25 is formed.
c, a discharge groove 21c for removing dust along each step 25.
Has been established. Each of the discharge grooves 21c has a width approximately equal to the radius of the pachinko ball, but may be any size as long as the pachinko ball does not fall therefrom and can flow down. Even in this case, the dust removing effect is sufficiently exerted as described above.
As shown in FIG. 7, the wall of each step 25 is slightly inclined at an upstream side with respect to the bottom wall 19c from below vertically. By doing so, there is an effect that dust easily falls. In addition, since the bottom wall 16c has a drop due to the provision of the step portion 25, an impact is given to the pachinko ball when the step portion 25 is dropped, and the dust attached to the pachinko ball drops well, and the impact Is transmitted as vibrations on the wall of the upstream pachinko ball or the ball passage 19c and propagates to the pachinko ball on the upstream side, causing ball crushing and preventing the ball pressure from being balanced on the downstream side, thereby preventing the ball from being clogged. A smooth flow of pachinko balls is ensured.

FIGS. 9 and 10 also relate to another embodiment, in which the bottom wall 16 of each of the three ball passages 19 is provided with a discharge groove 21 for removing dust along one side edge and the other side. And the tank rail 11 opened at different positions alternately with
Two vertical discharge grooves 26 are formed in the front wall 17 which is a side wall. Each of the discharge grooves 26 has a width approximately equal to the radius of the pachinko ball, but may have any size as long as the pachinko ball does not fall therefrom and can flow down. Even in this case, the dust removing effect is sufficiently exerted as described above. Further, as shown in FIG. 10, the front side wall 17a on the downstream side is inclined forward so that the lateral width of the ball passage 19 gradually increases toward the discharge groove 26 on the upstream side. By inclining in this manner, a step can be formed in the width direction of the ball passage 19, and the pachinko balls deviating from the step cause the ball passage 1 to move.
The ball of the pachinko ball in 9 is broken, the balance of the ball pressure to the downstream side is lost, and the vibration due to the impact is also generated, whereby the clogging of the ball is eliminated and the smooth flow of the pachinko ball is secured. become. Since other parts are the same as those of the present embodiment, detailed description is omitted by attaching the same reference numerals. Further, the discharge groove 26 may be applied to the front side wall of the auxiliary ball passage 20. The above configuration is more effective especially when the ball passages 19, 19a to 19c are wide such that the pachinko balls flow down in two or three rows simultaneously. Also, the discharge grooves 21c, 2
If the 6 is provided and they are related to each other, the dust removing effect is more effective.

FIGS. 11 and 12 show another embodiment applied to a connection portion between a tank rail 11d and a curve rail 12a. In this embodiment, a triple ball of a tank rail 11d is used. The bottom wall 1 over the passage 19d
At the downstream end of 6d, a stepped portion 25 whose downstream side is depressed is formed in a transverse shape. The stepped portion 25 is formed directly below the stepped portion 25, over the three ball passages 23a of the curve rail 12a, and on the bottom wall 27 thereof along the stepped portion 25. An exhaust groove 21d for removing dust is provided. Even in this case, the dust removing effect and the ball squeezing effect can be sufficiently exerted in the same manner as described above. Also in this case, similarly to the above, the wall of each step portion 25 is inclined slightly at an acute angle on the upstream side with respect to the bottom wall 16d from below vertically so that dust easily falls.

FIGS. 13 and 14 show another embodiment in which the same connection portion between the tank rail 11d and the curve rail 12a as described above is applied. In this embodiment, the downstream end of the tank rail 11d is used. A gap having a width slightly shorter than the radius of the pachinko ball is formed between the edge and the upstream end edge of the curve rail 12a. That is, the tank rail 1
A step 25 having a recessed downstream side is formed in the downstream edge of the bottom wall 16d of the three ball path 23a of the curve rail 12a just below the step 25 over the three ball paths 19d of 1d. A discharge groove 21d for dust removal is formed along the step 25 at the upstream end edge of the bottom wall 27. A discharge groove 26 is formed between the downstream edge of the front and rear side walls 15 and 17 of the tank rail 11d and the upstream end of the front and rear side walls 28 and 29 of the curve rail 12a. Even in this case, the dust-removing effect and the ball-compressing effect can be sufficiently exhibited in the same manner as described above. Further, the upstream side 28 of the front and rear side walls 28 and 29 of the curve rail 12a.
a, 29a are the upstream discharge grooves 2 as shown in FIG.
6 is inclined outward so that the lateral width of the ball passage 23a gradually increases. By inclining in this manner, a step is created in the width direction of the ball passage 19d and the ball passage 23a connected to the ball passage 19d. This also causes the pachinko balls in the ball passages 19d and 23a to be broken down and the ball to flow downstream. The pressure balance is lost, and furthermore, vibrations due to impact are generated, whereby the clogging of the balls is eliminated and a smooth flow of the pachinko balls is ensured. Since other parts are the same as those of the other embodiments, detailed description is omitted by attaching the same reference numerals.

As described above, the tank rail 11d and the curve rail 12a are arranged with a gap therebetween because, when they are arranged with their end faces joined as in the prior art, the joined end faces become front and rear. May be slightly off.
When such deviation occurs, the joint end face between the ball passage 19d of the tank rail 11d and the ball passage 23a of the curve rail 12a is displaced. As a result, not only the step formed by the side wall end face is formed in the ball passage, but the ball passage narrows. This is because dust easily accumulates on the step, which causes ball jamming. If a gap is opened, the distance between the side wall end faces at diagonal positions becomes longer, for example, the tank rail 11d and the curve rail 12a.
Even if they are slightly shifted back and forth, the ball passage will not be narrowed and no garbage will collect. Therefore, both rails 1
It is not necessary to pay much attention to the mounting of 1d and 12a, and the mounting is simplified.

As shown in FIG. 15, the ball rail 30 serving as the pachinko ball passage portion is generally provided with a ball leveling member 30 for aligning the pachinko balls so that they can flow smoothly and smoothly. A support 31 is provided so as to freely swing. Therefore, this ball 30
And the upstream side surface 32 against which the falling pachinko ball hits
A plurality of cross-shaped step portions 33 whose lower side is depressed may be provided on a. It is desirable that the space between the steps 33 is about the radius of a pachinko ball.
By providing the step portion 33 in this manner, the vibration caused by the impact is given to the pachinko ball, the ball breaking effect is exerted similarly to the above, the dust attached to the pachinko ball is well dropped and discharged from the discharge groove 21. Become. Also, the seed ball leveling 30 has conventionally been constituted by a plurality of members having two degrees of freedom in order to enhance the ball leveling effect. The ball 30 which can improve the effect can be provided at a low cost.

FIG. 16 shows a bent ball passage portion 122 of the curve rail 12, and the discharge groove 2 is formed in the bottom wall 27 over each ball passage 23.
In this case, the bottom wall 27 is provided with an opening 34 extending to each of the ball passages 23, and a ball which is freely rotated by a support shaft 35 near the lower side of the opening 34. An extraction member 36 is provided. A ball receiving piece 36 a extending from the support shaft 35 to one side and always closing the opening 34 is disposed on the ball removing member 36, but between the support shaft 35 and one inner peripheral edge of the opening 34. A discharge groove 21e for removing dust is formed on the substrate. The discharge groove 21e also has a width approximately equal to the radius of the pachinko ball, but may have any size as long as the pachinko ball does not fall therefrom and can flow down. A gap is also provided between the lower end edge of the ball receiving piece 36a and the inner peripheral edge of the opening 34. Further, a plurality of stepped portions 37 whose downstream side is depressed are formed on the upper surface of the ball receiving piece 36a. The interval between these steps 37 is preferably about the diameter of a pachinko ball. Even in this case, the dust removing effect and the ball squeezing effect can be sufficiently exerted in the same manner as described above. In addition, a detecting member (not shown) for detecting clogging of the ball in the ball tank 10 or the tank rail 11 may be rotatably provided near the opening 34 in addition to the ball removing member 36. However, also in this case, the discharge groove 21e can be formed similarly.

A step 38 is provided on the bottom wall 27 which is located on the downstream side of the curve rail 12 and is slightly upstream from the ball dispensing device 13 and which is inclined downward.
8 is formed and the bottom wall 27a on the upstream side and the bottom wall 27 on the downstream side are formed.
b, a vertical discharge groove 39 for removing dust is formed. The downstream bottom wall 27b is connected to the upstream bottom wall 27b.
a downwardly inclined toward the discharge groove 39,
The refuse that has fallen from the discharge groove 39 is easily discharged from the discharge groove 39. Also in this case, similarly to the above, the dust-removing effect and the ball-shrinking effect due to the vibration caused by the impact of the pachinko ball are sufficiently exhibited. In particular, in the ball breaking effect, in this case, since the speed of the pachinko ball flowing down is relatively high, the vibration of the impact due to the fall of the pachinko ball at the step portion 38 is reduced by the curve rail 12 and the tank rail 11. Propagation, and the pachinko spheres contained therein are broken down. The discharge groove 39 may be formed on the side wall instead of the bottom wall 27. In this case, the bottom wall 27b is inclined downward toward the discharge groove 39 side.

The lower end of the curve rail 12 is formed vertically, and the lower end of each ball passage 23 is supplied as a three-row vertical pachinko ball passage of a ball dispensing device 13 disposed below. Although connected to the passage 40, a projection 41 is provided on one side surface inside the flow lower end of each of the ball passages 23, and a step 42 is formed in which the downstream side is depressed. A discharge groove 43 for removing dust is provided below the step portion 42. In this case as well, the discharge groove 43 has a gap about the radius of the pachinko ball, but it is sufficient if the pachinko ball does not fall out of the gap and fall. Even in this case, the dust removing effect is sufficiently exerted as described above. Further, the pachinko ball flowing down to the projection 41 hits and the vibration caused by the impact propagates to the curve rail 12 and the tank rail 11 to break the ball of the pachinko ball therein. When the steps 37, 38, and 42 are provided in the curve rail 12, the curve rail 12 is where the pachinko balls flow relatively quickly due to the payout of the balls, and is compared with other pachinko ball passages. The impact of the pachinko ball is large, and the vibration is also widely propagated, which is extremely effective in preventing the pachinko ball in the tank rail 11 from being clogged. In addition, the direction of falling of the ball in the impacted pachinko ball is disturbed, whereby the ball pressure in the entire downflow direction of the pachinko ball is reduced, and the load due to the ball pressure applied to the ball dispensing device 13 can be reduced.

FIG. 17 shows a ball dispensing device 13a having a vertical portion and a pachinko ball passage whose lower end is bent substantially horizontally, in which a discharge groove 44 is opened in the supply passage 40. In this case, the vertical supply passage 40
A horizontal supply passage 40b is connected to the lower end of the flow path a, and communicates with the discharge chamber 45. In the discharge chamber 45, a lead screw 47 that horizontally rotates the pachinko ball that flows in by the drive motor 46 and pays out the pachinko ball is disposed. The lower end of the supply passage 40a is formed in an arc shape at the bent portion of the supply passage 40 at the center of the supply passage 40 and has a vertical upper surface along the longitudinal direction thereof. A ball receiving shelf 48 that tilts downward is provided,
Pachinko balls that flow down are flowing smoothly. Therefore, a discharge groove 44 for dust removal is formed in the bottom wall 49 of the horizontal supply passage 40b at the bent portion so as to face the vertical supply passage 40a and leave the ball receiving shelf 48. Even in this case, the dust removing effect is sufficiently exhibited.

In the ball dispensing device 13a, when the ball receiving shelf 48 is not provided as shown in FIG. 18, the ball dispensing device 13a is located on the corner portion on the bottom wall 49 of the horizontal supply passage 40b at the bent portion and A discharge groove 50 for removing dust is formed in contact with the side wall of the vertical supply passage 40a. The discharge groove 50 has a width approximately equal to the radius of the pachinko ball, but may be any size as long as the pachinko ball spills out of the pachinko ball and does not fall and can flow down. Even in this case, the dust removing effect is sufficiently exhibited.

In the present invention, the tank rail, the curve rail, and the supply passage of the ball payout device have been described as the pachinko ball passage portion. However, the pachinko ball passage portion is provided below the winning ball collecting cover that covers the back surface of the game board. A prize ball collecting trough for receiving a prize ball led out on the back of the game board, and a prize ball discharge passage for discharging the prize ball to the prize ball processing device or directly out of the pachinko game machine in connection with the prize ball collect gutter.
