Description

[Detailed Description of the Invention] (Industrial Field of Application) The present invention relates to a collection gutter that is placed on the back side of a game board of a pachinko machine to collect winning balls that have flowed out onto the back side of the game board.

(Prior art and its problems) The collection gutter is arranged to cover the back side of the game board, and collects winnings that flow out from various winning devices attached to the surface of the game board or winning openings to the back side of the game board. It has a rectifying shelf at the bottom that collects the balls, rectifies them one row at a time, and allows them to flow down to the ball controller of the winning ball processing device. In particular, the ball controller that is closely related to the rectifying shelf repeats the operation of tilting due to the weight of the ball each time a winning ball enters, and returning after releasing the ball. The balls ejected by this tilting action actuate the prize ball ejection mechanism to eject the prize balls corresponding to one winning ball. Such a ball controller requires about 1.3 seconds to process one winning ball as one action of ejecting a winning ball. Therefore, when a large number of winning balls are generated in a short period of time, such as with recent digital pachinko machines, it takes a long time to process the winning balls.
A large number of winning balls remain on the rectifying shelf of the collection gutter, and the tilting movement of the ball controller becomes unstable due to the ball pressure, making it impossible to eject the winning balls, or winning balls concentrate toward the ball controller. There were some inconveniences such as the accumulation of stones in the form of a stone wall, causing balls to become clogged.

In addition, on the back side of the game board covered by the collecting gutter, various winning devices and related equipment arranged on the surface of the game board, such as the back box of the ticket and the detector of the winning chuck, protrude. If a large winning device that generates a large amount of winning balls in a short period of time is installed together with these devices, the large rear mechanism of the device will occupy a large amount of the back surface of the game board, which will obstruct the winning balls flowing out from other winning devices. Cause a blockage or
Alternatively, in order to avoid this winning device, there were other inconveniences such as having to take an unreasonable detour or setting a flow path in a narrow area.

On the other hand, in an attempt to solve the above-mentioned inconvenience, if a dedicated channel for guiding a large number of winning balls is formed in the collection gutter, the installation position of the large winning device will be affected by the dedicated channel. Because of this, the problem arises that the use of the collecting gutter is limited to only a specific model, resulting in a loss of versatility of the component. Recent pachinko machines have a so-called separate structure in which the game board is integrated into a unit, and when replacing a new model with a new one, the mainstream method is to simply replace the game board while leaving the main body unchanged. Therefore, a collection gutter without versatility that requires replacement not only for the game board but also for the model is not practical.

(Purpose of the invention) In view of the above, an object of the present invention is to provide a collection gutter that is versatile and can smoothly guide a large number of winning balls.

(Structure of the invention) The present invention has an opening behind a specific winning device attached to the gaming board in the back plate of a collecting gutter that is placed on the back side of the game board and collects the winning balls that have flowed out onto the back side of the gaming board. An inlet for receiving winning balls from a winning device and an outlet opening on the upstream side of a rectifying shelf that is located at the bottom of the collection gutter and allows the collected winning balls to flow down to the ball controller while rectifying them in a single line. A guiding gutter with a bent part in the middle to reduce the downward force of the winning balls flowing down is superimposed on the back of the collection gutter between the inlet and the outlet, and the winning balls flow out from the specific winning device. The system is configured so that the winning balls that have been won are gently flowed down to a rectifying shelf by a guide gutter.

(Function of the invention) The winning balls that flowed out from the general winning device to the back of the game board are collected by the back plate of the collection gutter that covers the back of the game board.
While the winning balls are collected and flowed down on the rectifying shelf in the same way as in the conventional collecting gutter, the winning balls that flow out from a specific winning device that generates a large amount of winning balls in a short period of time are collected by the guide gutter on the back of the collecting gutter. It is guided to the upstream side of the rectifying shelf.
By passing through the bent part of the guide gutter, the downward force of the winning ball is reduced and the flow is rectified.
You will be gently guided to the rectifying shelf.

(Example) The present invention will be described below based on an example shown in the drawings.

First, the processing mechanism for winning balls will be explained with reference to FIGS. 1 and 2. The batted balls flowing out onto the back side of the game board 3 are collected by a collection gutter 4 arranged to cover the back side of the game board 3, and flow down as winning balls onto a rectifying shelf 5 formed at the bottom of the collection gutter 4. To go. The rectifying shelf 5 is located at the inner lower part of the collecting gutter 4, extends in the horizontal direction of the collecting gutter 4 so as to cross the winning ball flow path, and in FIG. The winning balls flowing down are rectified in a line and guided to a ball controller 6 disposed at the downstream end thereof.

The winning balls flow down guided by the rectifying shelf 5, and flow into the receiving portion 7 opened in the ball controller 6 facing the downstream end of the rectifying shelf 5 (see FIG. 7). When the ball controller 6 receives a winning ball, it tilts due to the weight of the winning ball and discharges the winning ball in the receiving section 7 to a winning ball collection gutter 8 located further downstream. While falling through the winning ball collecting gutter 8, the winning balls land on the swinging rod 9 protruding into the gutter and are pushed down, after which they are discharged to the outside of the machine.

On the other hand, the prize balls stored in the tank 11 located at the upper part of the back mechanism panel 10 are placed in the prize ball deriving chute 12 which derives the prize balls in the tank 11 into two strips, and on the downstream end side of the prize ball deriving chute 12. The ball flows down to the ball case 13 which accepts a predetermined number of prize balls and fills them. When the swinging rod 9 is pushed down, the ball sheath case 13 simultaneously tilts via the interlocking rod 14 and releases a predetermined number of prize balls into the prize ball discharge gutter 15. The released prize balls fall onto the damper 16 in the prize ball gutter, collide with the prize ball discharge bell 17 and ring the bell, and then pass through the prize ball discharge port 18 drilled in the game board 3 to the pachinko machine. It is discharged into a ball tray (not shown) on the front side. Note that the ball controller 6 returns in conjunction with the operation of the damper 16. and,
Furthermore, if there is a winning ball on the rectifying shelf 5, it is accepted and the winning ball processing operation is started again.

In FIGS. 2 and 3, 4 is a collection gutter.
The collection gutter 4 is located on the back side of the game board 3 and is arranged to collectively cover the rear mechanisms of the various winning devices 1 and 2 attached to the surface of the game board 3 that are exposed on the back side of the game board. , to collect the winning balls flowing out from the rear mechanism to the back surface of the game board 3.

The collecting gutter 4 shown in the figure is formed separately above and below an upper collecting gutter 4A and a lower collecting gutter 4B. Then, the back mechanism board 10 is the game board 3.
When brought into contact with the back side, the upper part 4A and the lower part 4B match to form a collection gutter 4.
The back mechanism panel 10 has a ball controller 6 that allows the winning balls to flow down one by one.
It is located in B. In the embodiment, the collecting gutter 4 is configured separately into an upper collecting gutter 4A and a lower collecting gutter 4B, but they may be formed integrally with the back mechanism panel 10.

22 is an induction gutter. The guiding gutter 22 guides winning balls from a specific winning device that generates a large amount of winning balls in a short period of time to the upstream part of the rectifying shelf 5 when the guiding gutter 22 is opened. In order to reduce the ball pressure and slow down the flow rate, the flow path has a bent part 23A bent in the middle.

The guide gutter 22 of the embodiment is installed for the purpose of flowing down the winning balls of the large winning device 1 attached to the upper center of the game board 3. This induction gutter 22
is formed by overlapping the back plate 19 constituting the collecting gutter 4 (the upper part 4A of the collecting gutter) so that the collecting gutter 4 and the back plate 19 are shared. Induction gutter 2
An inlet 20 for receiving two winning balls is provided in the back plate 19 behind the large winning device 1, and an outlet 21 is provided in the back plate 19 on the upstream side of the rectifying shelf 5.

The introduction port 20 is simply an opening in the back plate 19 of the collection gutter 4 as shown in FIGS. 5 and 6, and the winning balls from the large winning device 1 are introduced through the introduction gutter 26. ing. The introduction gutter 26 of the embodiment is formed separately from the collection gutter 4, and the upstream end of the introduction gutter 26 is provided and fixed integrally with the large winning device 1 on the front side of the game board 3, and the downstream end is formed separately from the collection gutter 4. It is extended so as to face the inlet 26 of the. In addition, the introduction gutter 20 is the collection gutter 4.
It may be formed integrally with the collecting gutter 4 so as to extend from the inlet 20 to the large prize winning device 1 side. Note that 27 in the figure is a downstream space formed when the collecting gutter 4 covers the back surface of the game board 3, and is a space into which general winning balls flow down.

The discharge port 21 is opened in the back plate 19 of the collecting gutter 4 so as to face the upstream end of the rectifying shelf 5. This outlet 2
1 is preferably provided on the upstream side of the straightening shelf 5, relatively far away from the ball controller 6 at the downstream end of the straightening shelf 5. This is because if it is provided far away, there will be room for the winning balls that are guided down the guide gutter 22 to be rectified step by step on the rectifying shelf 5.

The illustrated discharge port 21 has a diversion gutter 24 that protrudes into the collection gutter 4 and regulates the flow direction of the winning balls in the flow direction of the rectifying shelf 5. The outlet of the diverting gutter 24 has a diameter that allows about one to two winning balls to be discharged. In the embodiment, the diverting gutter 24 is formed integrally with the discharge port 22, but it may be formed separately.

The guide gutter 22 is arranged on the outside of the back plate 19 so as to communicate the inlet 20 and the outlet 21. In this case, instead of connecting the inlet 20 and the outlet 21 by the shortest distance, a bent portion 23A is formed in at least one location along the way to detour the flow path. By forming the bent portion 23A, the speed of the winning balls flowing down is relaxed, and the ball pressure between the winning balls flowing down is reduced. Therefore, the larger the degree of curvature, the more effective it is, and the longer the guide gutter 22 is, the more effectively it is possible to rectify the winning balls flowing down.

In the embodiment, the central part of the guide gutter 22 is bent into a substantially dogleg shape to form a bent part 23A, and the flow direction of the downstream part of the guide gutter 22 on the downstream side of the bent part 23A is aligned with the rectifying shelf 5. The direction of flow is opposite to the direction of flow. The bent portion 23A may be configured by adding a step to the flow path.

Further, in the embodiment, as described above, the outlet 21 is provided with the diverting gutter 24 for directing the winning balls flowing down the guiding gutter 22 in the downstream direction of the rectifying shelf 5. As described above, in the embodiment, in addition to the bent portion 23A, a second
Since the diverting gutter 24, which can also be called a bent part, is provided, the downward pressure and velocity of the winning balls are delicately adjusted, and the winning balls are guided onto the rectifying shelf 5 more gently.

A ball leveling member 28 is suspended from above the rectifying shelf 5 in order to perform the rectifying action even more effectively. In the embodiment, a spherical leveling member 28 is constructed by pivoting a spherical leveling weight that swings in the downstream direction of the rectifying shelf 5 to a shaft extending from the inner surface of the back plate 19 of the collecting gutter 4 onto the rectifying shelf 5. Three of them are arranged from the upstream to the downstream of the guide shelf 5. With this, the induction gutter 2
The winning balls that have flowed in in large quantities from No. 2 are reliably leveled in a row.

Although the above embodiment is an example applied to a model equipped with a large winning device 1, the collecting gutter 4 of the present invention can also be used in a model not equipped with a large winning device. This is because even if winning balls flow into the introduction port 20, they will eventually be guided to the rectifying shelf 5. Therefore, the use of the collecting gutter 4 of the present invention is not limited to a specific model, but can be used as a general-purpose component.

(Effect of the invention) The present invention has an opening behind a specific winning device attached to the gaming board in the back plate of the collecting gutter which is placed on the back side of the game board and collects the winning balls that have flowed out onto the back side of the gaming board. An inlet for receiving winning balls from a winning device and an outlet opening on the upstream side of a rectifying shelf that is located at the bottom of the collection gutter and allows the collected winning balls to flow down to the ball controller while rectifying them in a single line. A guiding gutter with a bent part in the middle to reduce the downward force of the winning balls flowing down is superimposed on the back of the collection gutter between the inlet and the outlet, and the winning balls flow out from the specific winning device. Since the winning balls are configured so that they flow gently down to the rectifying shelf through the guide gutter, it is possible to guide a large number of winning balls to the rectifying shelf through a flow path different from that of normal winning balls. It is possible to eliminate clogging of balls on the rectifying shelf.

Furthermore, even if a recent digital pachinko machine is equipped with a large winning device that generates a large amount of winning balls in a short period of time, those winning balls will flow into the guide gutter in a state where the downward force is reduced. As a result, a large amount of winning balls accumulates in the collecting gutter, especially on the rectifying shelf, and the ball pressure causes the operation of the ball controller to become unstable, making it impossible to eject winning balls, or causing damage to the ball controller. It is possible to eliminate inconveniences such as the winning balls concentrated in the direction of each other and stacking up like a stone wall, causing ball jams.

Furthermore, the use of the collection gutter is not limited to a specific model, but can be used as a general-purpose component.
