Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention effectively pools the safe balls collected in the safe ball collection path formed in the winning space of the mechanism board installed on the back of the game board. This invention relates to a pachinko machine that can perform storage and discharge processing.

[Prior Art] Recently, as is well known, in pachinko machines, the winning hole of a winning ball device installed on the surface of the game board is opened wide using a specific safe ball, or is kept open for a relatively long time. However, most of them are of a type that generates many safe balls at once. On the other hand, the behind-the-scenes mechanism for handling safe balls is old-fashioned; for example, a safe ball gathering passageway for storing and discharging safe balls is simply provided in an inclined manner in the lower part of the winning space. There are many things.

[Problem that the invention aims to solve] For this reason, in conventional pachinko machines, if a large number of safe balls are collected in a safe ball collection path on a mechanism board installed on the back of the game board in a short period of time, they cannot be processed. These safe balls waiting to be processed are accumulated one after another inside the passage. As a result, balls may become jammed in the safe ball collection path, making it impossible to release prize balls, or the accumulated safe balls may ride on the operating member of the prize ball receiver that protrudes from the back of the game board, impeding normal operation. There were problems such as:

This invention was created in view of the above points, and even if a large number of safe balls are collected at once in the safe ball collection path formed in the winning space, they can be pooled in an orderly manner and disposed of one by one without fail. The aim is to provide pachinko machines with a high level of quality.

[Means for solving the problem] In order to achieve the above object, in the present invention, a winning space is formed on the front side of the game board, which is attached to the back side of the game board so as to be openable and closable. In a pachinko machine equipped with a mechanical plate, an inclined upper safe ball collecting passage and a lower safe ball collecting passage are provided in a step-like manner in the lower part of the winning space, and the lower part of the winning space is provided with an inclined upper safe ball collecting passageway in a stepped manner. disposing a ball lifting device, communicating a lower inclination end of the lower safe ball collection passage with a lower introduction part of the ball lifting device;
The upper discharge part of the ball raising device is communicated with the upper safe ball collecting passage through the inclined passage, and the safe balls collected in the lower safe ball collecting passage are transported to the upper safe ball collecting passage by driving the ball raising device. Furthermore, the inclined lower end of the upper safe ball collection passage is communicated with the safe ball discharge port of the mechanism plate.

[Operation] The safe balls guided into the winning space of the mechanism board fall into the upper safe ball collecting section and are guided to the safe ball discharge port, after which they are discharged out of the machine while performing a prize ball discharge operation. On the other hand, when safe balls are accumulated in the upper safe ball collecting section, safe balls that fall into the upper safe ball collecting section fall into the lower safe ball collecting section. The balls are then guided to the lower introduction part of the ball lifting device and lifted up one by one, and then guided from the upper discharge part to the upper safe ball collecting part via the inclined passage. This makes it possible to reliably discharge the safe balls one by one.

[Example] An example of the present invention will be described below with reference to the drawings.

In the figure, 1 is the pachinko machine body, 2 is the game board, 3 is the safe hole drilled through the game board 2, and 4
is a mechanism plate that is installed on the back side of the game board 2 with one side pivoted so that it can be opened and closed. Game board 2 of this mechanism board 4
A winning space 5 is formed on the inner surface facing the game board 2 at a constant distance from the back surface of the game board 2, and the surface thereof is equipped with a well-known back mechanism such as a ball tank and a prize ball ejection mechanism.

However, in the present invention, the input prize space 5
An inclined upper safe ball collecting passage 6 and a lower safe ball collecting passage 7 are provided in a step-like manner in the lower part of the inside.
Also, a mechanism plate 4 located at the inclined lower end side of the upper safe ball collecting passage 6 and the lower safe ball collecting passage 7 is provided.
A ball lifting device 11 is disposed on the side of the ball.

As shown in FIG.
An endless belt 15 with magnets 14 attached at regular intervals on the outer peripheral surface is stretched between the two rollers, and one roller 12 is driven by a motor 16 to move the belt 15 from below to above (see Fig. 4). direction). Then, the lower introduction part of the ball raising device 11 is connected to the inclined lower end of the lower safe ball collecting passage 7, and the upper discharge part of the ball raising apparatus 11 is connected to the upper safe ball collecting passage 6 through the obstruction plate 17 and the inclined passage 18. It communicates with the upper part of the lower end of the slope. The obstacle plate 17 is provided in the ball raising device 11 so as to face and approach the magnet 14 rising toward the upper ejection section, and is provided with a slight downward inclination toward the inclined passage 18. . In addition, the inclined passage 18
is for guiding the safe balls carried upward by the ball lifting device 11 to the upper safe ball collecting passage 6.

In addition, the inclined lower end of the upper safe ball gathering passage 6 is
It communicates with a safe bulb discharge port 9 opened in the mechanism plate 4 via a bent passage 8. A side wall plate 10 is provided near the inclined lower end of the upper safe ball collecting passage 6 and at the side end of the bending passage 8 portion, and the safe balls lined up near the inclined lower end of the upper safe ball collecting passage 6 are placed in the lower safe ball collecting passage. The ball is surely guided to the safe ball discharge port 9 without falling into the ball 7.

The safe ball discharge port 9 faces a safe ball organizer 19 that is swingably provided on the surface of the mechanism plate 4. The safe ball organizer 19 has a well-known structure that allows safe balls to flow down one by one intermittently into a safe ball flow down gutter to perform a prize ball release operation. Further, the motor 16 can be driven in various ways, such as when the operating handle on the front of the machine is operated or when a switch detects that safe balls are pooled in the lower safe ball collecting passage 7.

Next, the operation of the present invention constructed as described above will be explained. When the safe balls B flow out from the safe hole 3 of the game board 2 into the prize winning space 5 of the mechanism board 4, these safe balls B mainly fall into the upper safe ball collection passage 6 due to the momentum of the flow out, and the safe balls are ejected. You will be led to Exit 9. Then, as is well known, the balls are received one by one by the safe ball organizer 19 and flow down the safe ball flow down gutter while being oscillated, and along the way, a prize ball discharging operation is performed to discharge them out of the machine. On the other hand, if a large number of safe balls B flow into the winning space 5 in a short period of time, the safe balls B cannot be discharged in time by the safe ball organizer 19, and these safe balls B are accumulated in the upper safe ball collection passage 6. In this state, when the safe balls B flow out into the winning space 5 one after another, these safe balls B move from the upper safe ball collecting passage 6 and fall into the lower safe ball collecting passage 7. and,
The safe balls B that have fallen into the lower safe ball collection passage 7 and are once pooled are attracted one by one to the magnetic material 14 attached to the outer circumferential surface of the belt 15 of the ball lifting device 11 that rotates by the drive of the motor 16. They are held and carried upwards, and are forcibly detached from the magnet body 14 by contacting the obstacle plate 17, and fall from the inclined passage 18 to near the inclined lower end of the upper safe ball collection passage 6, where they are sequentially discharged. be done. It is preferable that the motor 16 be set to rotate slowly and at a constant speed in consideration of the time required for the discharge processing operation.

As explained above, the present invention forms an upper safe ball collecting passage 6 communicating with the safe ball outlet 9 in the lower part of the winning space 5 of the mechanism plate 4, and furthermore, an upper safe ball collecting passage 6 in the lower part thereof. Since the lower safe ball collecting passage 7 that pools the balls falling from the lower part 6 is formed in a step-like manner, the storage capacity of safe balls is greatly increased compared to the safe ball collecting passage formed in the winning space of the conventional mechanism board. Can be increased.

These safe balls are appropriately distributed and pooled in the upper safe ball collecting passage 6 and the lower safe ball collecting passage 7, and the safe balls pooled in the lower safe ball collecting passage 7 are raised by the ball lifting device 11. Since the safe balls are transported one by one to the upper safe ball collecting passage 6 for discharge processing, even if many safe balls flow into the winning space 5 at once, a large amount of safe balls will not be accumulated in the upper safe ball collecting passage 6. As a result, it is possible to reliably eliminate the drawback of the conventional method in which the ball gets stuck at the safe ball outlet 9 due to the ball pressure.

[Effect of the invention] Therefore, according to the pachinko machine of the present invention, the prize ball discharging mechanism of the conventionally used mechanism board can be used as is without any design changes, and the prize ball discharging mechanism of the mechanism board can be ejected into the lower part of the winning space in front of the mechanism board. An upper safe ball collection passageway and a lower safe ball collection passageway that communicate with the safe ball discharge port are provided in a stepped manner, and the pooled safe balls that have fallen into the lower safe ball collection passageway are sequentially transferred to the upper safe ball collection passageway using a ball lifting device. Since the safe balls are transported by air, pooling and discharging of a large number of safe balls can be carried out reliably and orderly. In addition, by extending the lower safe ball gathering passage 7 further downwards than the winning space of the conventional mechanism board, it is possible to install the winning ball device even at a low position on the game board, which was previously considered difficult. This has the effect of making it possible to diversify the gauge configuration on the game board surface.
