Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine in which a ball removing passage for discharging pachinko balls stored in a pachinko machine out of the machine is joined to a prize ball collecting gutter for collecting prize balls. It is.

[0002]

2. Description of the Related Art In a conventional general pachinko machine, a prize ball which has won a prize port of a game board or a prize device is collected by a prize ball collecting trough on the back side of the game board, and the prize ball collecting trough is formed. The prize-ball detecting device provided at the downstream side of the prize detects the prize-balls one by one and discharges them one by one out of the machine. However, in recent pachinko machines, a winning ball sensor provided for each winning opening / winning device is used to detect a winning ball, so that it is necessary to provide a winning ball detecting device downstream of the winning ball collecting gutter. Has disappeared, and the winning balls collected by the winning ball collecting gutter have been discharged to the outside as it is.

[0003] Focusing on this point, a ball removal passage for discharging the pachinko balls stored in the machine to the outside of the machine is merged with the winning ball collecting gutter, and the ball is removed using the discharging passage of the winning ball. By performing the above, it is considered that the flow path configuration on the back side of the pachinko machine is simplified.

[0004]

Generally, a variable winning device is provided on the lower side of the game board, and the rear of the variable winning device protrudes to the back side of the game board, so that the rear portion of the variable winning device wins. It is in a state of protruding to a relatively close position above the ball collecting gutter. At the time of ball removal, a large amount of pachinko balls stored in ball tanks and tank rails are pushed out by the subsequent ball pressure and fall vigorously in the ball removal passage toward the bottom of the winning ball collecting gutter, Pachinko balls falling from the passage violently collide with the bottom of the winning ball collecting gutter and bounce high, and the bouncing balls collide with the rear of the variable winning device protruding behind the game board, and the sensors and connectors of the variable winning device Parts may be damaged.

[0005] The present invention has been made in view of such circumstances, and its object is to provide a back surface of a game board by jumping up of a pachinko ball that falls from a ball-pulling passage to a winning ball collecting trough when a ball is pulled out. It is an object of the present invention to provide a pachinko machine that can prevent the side components from being damaged.

[0006]

In order to achieve the above object, a pachinko machine according to the first aspect of the present invention is characterized in that a ball removing passage is joined to a winning ball collecting gutter and a ball is discharged through a common discharging passage with the winning ball. In the punching device, the ball-passing passage is provided with a speed-reducing means for reducing the flow speed of the pachinko balls flowing down the ball-passing passage. With this configuration, when the ball is removed, the falling speed of the pachinko ball flowing down the ball removal passage can be reduced by the deceleration means, so that the pachinko ball falling from the ball removal passage gently collides with the bottom surface of the winning ball collecting gutter. As a result, the bouncing of the pachinko ball on the bottom surface of the winning ball collecting gutter can be suppressed to a low level. As a result, it is possible to avoid as much as possible that the pachinko balls that have fallen from the ball-pulling passage to the winning ball collecting gutter and bounce up hit the parts on the back side of the game board (for example, the rear part of the variable winning device). First, even if the jumping ball collides with a component on the back side of the game board, the collision is very weak), and damage to the component on the back side of the game board can be prevented. In addition, by suppressing the bouncing of the pachinko balls in the winning ball collecting gutter, the pachinko balls that have fallen into the winning ball collecting gutter from the ball extraction passage can smoothly flow down the downstream side of the winning ball collecting gutter.

In this case, for example, by providing a bent passage portion as a deceleration means in the ball emptying passage, the falling speed of the pachinko ball flowing down the ball emptying passage may be reduced, but in order to obtain a sufficient deceleration effect. It is necessary to make the bent passage part undulate to some extent in the horizontal direction with respect to the falling direction of the pachinko ball, so the arrangement space for the ball extraction passage becomes large in the lateral direction, and the arrangement space for other parts It becomes narrow.

[0008] In view of the above, according to a second aspect of the present invention, the deceleration means includes:
You may make it comprise the protrusion part provided in the inner wall of the ball | bulb passage. With this configuration, even if the ball-passing path is formed linearly in the falling direction, the pachinko ball flowing through the ball-pulling path collides with the projection, thereby reliably reducing the flow-down speed of the pachinko ball. Therefore, the space for arranging the ball empty passage in the lateral direction can be reduced, and the space for arranging other parts can be widened.

Further, it is preferable that the projections are formed at alternate positions between the inner walls facing each other in the ball-drawing passage. With this configuration, the pachinko balls can be caused to flow down in a zigzag manner while alternately colliding with the projections of the opposing inner walls in the ball emptying passage, and the flow-down speed of the pachinko balls can be effectively reduced. .

[0010] According to a fourth aspect of the present invention, a bounce ball protection means is provided in the vicinity of the confluence of the ball extraction passage and the winning ball collecting gutter to repel a pachinko ball that has jumped up on the bottom surface of the confluence. You may do it. In this way, even if the pachinko ball jumps vigorously at the bottom of the converging portion of the winning ball collecting gutter, the ball can be bounced downward by the ball protection means, The components on the back side of the game board can be protected from climbing balls, and the components on the back side of the game board can be prevented from being damaged.

[0011]

A ball tank 13 for storing pachinko balls is provided on the upper rear surface of the mechanism plate 12, and a tank rail 14 for flowing down the pachinko balls flowing out of the ball tank 13 in an aligned state is connected to the ball tank 13. A ball supply path 15 is provided at the lower end of the tank rail 14,
A ball payout device 16 is connected to the lower end of the ball supply path 15. Further, on the side of the ball supply path 15, there is provided a ball removing passage 17 for discharging pachinko balls stored in the pachinko machine out of the machine, and a ball removing device 18 is provided near the outlet of the tank rail 14. Is provided. The ball removing device 18 normally locks the switching valve 19 to the normal position and holds the downward flow of the pachinko ball in the ball supply path 15, and removes the switching valve 19 by operating the lever member 20 when removing the ball. By switching to the position, the downstream of the pachinko ball is switched from the ball supply path 15 to the ball removal path 17.

Next, the structure of the front side of the mechanism plate 12 will be described. As shown in FIG. 2, a winning ball collecting gutter portion 22 is provided at a lower portion of the front surface of the mechanism plate 12, that is, at a position corresponding to a lower portion of the lower surface of the game board 21 (see FIG. 4). The bottom surface 22a of the winning ball collecting gutter portion 22 is formed so as to incline downward from both sides of the mechanism plate 12 toward the center. The winning ball collecting gutter portion 22 allows the winning opening of the game board 21 and the winning device (both). (Not shown) and the variable prize winning device 23 (see FIG. 4). A discharge passage 24 communicating with the outside of the machine is connected to the most downstream portion of the winning ball collecting gutter portion 22.

A ball-passing passage 25 is provided on the front side of the mechanism plate 12, and the lower end of the ball-passing passage 17 on the back side of the mechanism plate 12 is connected to the mechanism plate 12 through a communication passage 26. It is connected to the upper end of the ball-passing passage 25 on the front side. This ball emptying passage 25 is formed so as to extend linearly downward, and has an oblique passage portion 2 formed at a lower end portion.
7 is connected to the winning ball collecting gutter 22.

As shown in FIG. 1, a plurality of projections 28 (deceleration means) for reducing the flow speed of the pachinko ball are formed at alternate positions on the left and right inner walls in the middle of the ball emptying passage 25. ing. The upper surface 28a of each projection 28 is formed so as to be inclined downward toward the center of the ball-passing passage 25, so that the pachinko ball colliding with the upper surface 28a of the projection 28 rebounds to the inner wall side facing the pachinko ball. I have. This allows the pachinko balls in the ball-pulling passage 25 to flow down in a zigzag manner while alternately colliding with the left and right protrusions 28.

In the present embodiment, in order to achieve both deceleration of the pachinko ball and good ball flow, for example, the height of each projection 28 (the horizontal dimension in FIG. 1) is one of the diameter of the pachinko ball.
/ 2, and the width of the ball-passing passage 25 is set such that the effective passage width at the position where each projection 28 is formed is slightly larger than twice the diameter of the pachinko ball. ing. It goes without saying that the dimensions of each part may be changed as appropriate according to the model of the pachinko machine.

A ball protection wall 29 (bounce ball protection means) is provided at the outlet of the ball passage 25 (the outlet of the oblique passage 27) so as to face the bottom surface 22a of the winning ball collecting gutter 22. And the bottom surface 2 below the outlet portion of the ball emptying passage 25
The pachinko ball that jumped up in 2a is rebounded downward by the ball protection wall 29.

A plurality of steps are provided on the bottom surface 22a of the winning ball collecting gutter 22, as shown in FIGS.
By decelerating the momentum of the pachinko ball that has flowed down due to this step, it rebounds and the bottom surface 22a is formed by the pachinko ball.
To prevent damage.

As shown in FIG. 4, a variable winning device 23 is provided below the game board 21. Since the rear portion 23a of the variable winning device 23 projects behind the gaming board 21, the rear portion 23a of the variable winning device 23 projects to a relatively close position above the winning ball collecting gutter portion 22. . The rear portion 23a of the variable winning device 23 is provided with a sensor 30 for detecting a winning ball, a connector (not shown) for electrically connecting the variable winning device 23 to a control circuit and the like.

In the pachinko machine 11 configured as described above, during the game, the winning balls that have won the winning opening, the winning device, and the variable winning device 23 of the game board 21 are changed to the winning ball collecting gutter 22.
And discharged from the discharge passage 24 to the outside of the machine.

On the other hand, when the ball is to be removed from the pachinko machine, the downfall of the pachinko ball stored in the ball tank 13 or the tank rail 14 is transferred from the ball supply path 15 to the ball removal passage 17 by the ball removal device 18. Switch. As a result, the pachinko balls stored in the ball tank 13 and the tank rail 14 pass through the ball removing passage 17 on the rear side of the mechanical plate 12 through the ball removing passage 25 on the front side of the mechanical plate 12 to enter the winning ball collecting gutter 22. And is drawn out of the machine from the common discharge passage 24 with the winning ball.

During the ball removal, a large amount of pachinko balls stored in the ball tank 13 and the tank rail 14 are pushed out by the subsequent ball pressure, and the ball removal passage 17 on the rear side of the mechanism plate 12 is pressed.
Flows into the ball-passing passage 25 on the front side of the mechanism plate 12, but in the present embodiment, the left and right inner walls of the ball-passing passage 25
Since the projecting portions 28 are provided alternately, the ball removing passage 2
The pachinko ball can be caused to flow down in a zigzag manner while alternately colliding with the protrusions 28 on the left and right inner walls in the inside 5, and the flow speed of the pachinko ball can be sufficiently reduced.
For this reason, the pachinko balls falling from the ball-pulling passage 25 come into gentle collision with the bottom surface 22a of the winning ball collecting gutter portion 22, and the bouncing of the pachinko balls on the bottom surface 22a of the winning ball collecting gutter portion 22 is suppressed low. Can be.

Further, since the ball-deflecting ball protection wall 29 is provided at the exit of the ball-pulling passage 25, the pachinko ball wins without being able to sufficiently reduce the falling speed of the pachinko ball in the ball-pulling passage 25. Even if the ball jumps up vigorously on the bottom surface 22a of the ball collecting gutter portion 22, the ball can be bounced downward by the ball protection wall 29.

Therefore, in this embodiment, the pachinko ball that has fallen from the ball empty passage 25 to the winning ball collecting gutter 22 by both the projection 28 and the ball protection wall 29 is used to remove the pachinko ball from the rear portion 23 a of the variable winning device 23. The collision with the components on the back side of the game board 21 can be reliably avoided, and the components on the back side of the game board 21 can be prevented from being damaged. Moreover,
By suppressing the bouncing of the pachinko balls on the bottom surface 22a of the winning ball collecting gutter portion 22, the pachinko balls that have fallen into the winning ball collecting gutter portion 22 from the ball removal passage 25 flow smoothly to the discharge flow passage 24, Can be discharged outside.

By the way, for example, the downflow speed of the pachinko balls in the ball-passing passage 25 may be reduced by providing a bent passage portion as a speed reduction means in the ball-passing passage 25, but it is necessary to obtain a sufficient deceleration effect. Since it is necessary to make the bent passage part undulate to some extent in the horizontal direction with respect to the falling direction of the pachinko ball, the space for arranging the ball emptying passage 25 becomes large in the horizontal direction, and the space for arranging other parts is correspondingly increased. Becomes narrower.

In this regard, in this embodiment, since the projection 28 is provided on the inner wall of the ball-passing passage 25 as the speed-reducing means, the ball-passing passage 25 can be formed linearly in the falling direction. When the pachinko balls flowing through the ball removing passage 25 collide with the projections 28, the falling speed of the pachinko balls can be reliably reduced. Therefore, the space for arranging the ball-passing passage 25 in the lateral direction can be reduced, and the space for arranging other parts can be widened. It is possible to cope with an increase in size.

In the above-described embodiment, both the speed reduction means (projection 28) and the ball protection means (bounce ball protection wall 29) are provided. However, only one of the speed reduction means and the ball protection means is provided. May be provided, and even in this case, the intended object of the present invention can be achieved.

In addition, according to the present invention, a protrusion may be formed on the inner wall before and after the ball passage 25, or a protrusion may be formed on the inner wall of the ball passage 17 on the back side of the mechanism plate 12. ,
The present invention can be implemented by appropriately changing the positions and shapes of the projections and the ball protection wall.

[0028]

As is apparent from the above description, according to the pachinko machine of the first aspect of the present invention, since the ball-passing passage is provided with the speed-reducing means for reducing the falling speed of the pachinko balls, the ball-passing passage is provided. The pachinko balls that fall into the winning ball collecting gutter can be prevented from jumping up, and the parts on the back side of the game board can be prevented from being damaged by the bouncing balls, and the pachinko balls that have fallen into the winning ball collecting gutter. The ball can smoothly flow down the downstream side of the winning ball collecting gutter.

According to the second aspect of the present invention, since the speed reduction means is constituted by a projection provided on the inner wall of the ball-drawing passage, even if the ball-drawing passage is formed linearly in the falling direction, the pachinko ball falling speed is reduced. Can be surely decelerated, and the requirement for space saving of the ball empty passage can be satisfied while having a deceleration function.

Furthermore, in the third aspect, since the projections are formed at alternate positions of the opposing inner walls of the ball removing passage, the pachinko balls alternately strike the opposing projections of the opposing inner walls in a zigzag shape. The speed of the pachinko ball can be further reduced.

According to the fourth and fifth aspects of the present invention, there is provided a bounce ball protection means in the vicinity of the confluence of the ball extraction passage and the winning ball collecting gutter to repel the pachinko ball which has jumped up on the bottom surface of the confluence. Even if the pachinko ball jumps vigorously at the bottom of the junction, the jumping ball can be bounced downward by the ball protection means, and the same effect as in claim 1 can be obtained.
