DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a pachinko machine having an improved ball tray for receiving pachinko balls.

[0002]

2. Description of the Related Art In recent years, pachinko machines tend to increase the number of pitches at the time of a big hit. However, simply increasing the capacity of the ball dish increases the amount of stored pachinko balls, which increases the back pressure (load from the subsequent pachinko balls) applied to the pachinko balls downstream of the ball dish, and However, there is a possibility that the ball flow may be deteriorated by forming a bridge.

Therefore, as disclosed in Japanese Patent Application Laid-Open No. 9-24134, it has been proposed to increase the capacity of a ball dish by elastically supporting a bottom plate of the ball dish so as to be tiltable. As this ball dish increases the amount of stored pachinko balls, the bottom plate of the ball dish tilts due to the load of the pachinko balls to reduce the downward slope, and the back pressure applied to the pachinko balls on the downstream side is suppressed to an appropriate level, This prevents the pachinko balls from forming a bridge and causing the ball flow to deteriorate.

[0004]

However, the ball tray disclosed in the above-mentioned publication has a limit in capacity expansion. In other words, up to a certain amount of storage, the bottom plate of the ball dish tilts and the gradient can be reduced to suppress the increase in back pressure, and the ball flow does not deteriorate, but the tilt range of the ball dish bottom plate is also limited. When the storage amount is increased beyond that, the increase in back pressure cannot be sufficiently suppressed, and the ball flow becomes worse. Therefore, the storage amount can be increased only within a range in which the bottom plate of the ball dish can tilt, and the capacity of the ball dish has not been effectively increased.

[0005] The present invention has been made in view of such circumstances, and accordingly, an object of the present invention is to provide a pachinko machine that can realize a larger capacity of a ball dish without deteriorating the ball flow. To provide.

[0006]

According to a first aspect of the present invention, there is provided a pachinko machine according to the present invention, comprising a ball plate for receiving pachinko balls, wherein the ball plate is provided at a lower portion of the pachinko machine main body. And a rear plate portion which protrudes forward from the position of the front panel and a rear plate portion which enlarges a storage space for pachinko balls rearward from the position of the front panel.

In this configuration, by adding a rear plate portion at the front of the front panel to the front plate at the front of the front panel, the storage space for the pachinko balls can be expanded rearward, and more pachinko balls are stored. be able to. Moreover, instead of stacking pachinko balls high in the bowl, pachinko balls can be stored relatively shallowly in the wide storage space that expands backwards. The effect on the sphere is small, and the back pressure is not so high. Further, since the ball plate is enlarged backward, the amount of protrusion of the ball plate to the front can be made equal to that of the conventional ball plate, and the ball plate does not become an obstacle.

In this case, the front plate portion and the rear plate portion are separated back and forth by a partition wall, and the bottom surface of the front plate portion is inclined downward toward the ball launching device. The pachinko ball in the front plate portion is caused to flow down to the ball launching device side, a prize ball is received in the rear plate portion, and the bottom surface of the rear plate portion is inclined downward in a direction opposite to the front plate portion, and A communication port for communicating the downstream side of the plate portion with the upstream side of the front plate portion may be formed in the partition wall.

With this configuration, the pachinko ball received as a prize ball in the rear plate portion flows down the upstream of the front plate portion along the inclination of the bottom surface of the rear plate portion, and passes through the communication port. After moving into the front plate portion, the pachinko balls in the rear plate portion flow down toward the ball launching device, which is the direction opposite to the flow down direction of the pachinko balls. This effectively prevents the flow pressure of the pachinko spheres in the rear plate from being applied in the downward direction of the pachinko spheres in the front plate, and increases the amount of stored pachinko balls in the rear plate.
Back pressure applied to the pachinko ball downstream of the front plate does not increase so much.

On the other hand, if the front plate portion and the rear plate portion are separated back and forth by the partition wall, the state of storage of the pachinko balls in the rear plate portion may not be easily understood from the player side. Preferably, at least a part of the partition wall is formed of a transparent member. With this configuration, the player can check the presence or absence of the pachinko balls, the amount of stored pachinko balls, the flow of the balls, and the like in the rear plate portion by looking into the rear plate portion through the transparent member.

Furthermore, an illumination lamp may be provided to illuminate the rear plate portion. This makes it easier to confirm the situation inside the rear plate portion.

In the pachinko machine configured as described above,
When the pachinko balls hit into the gaming board 12 win, for example, one of the starting winning opening 14, the variable winning device 15, the winning opening 16, and the winning device 17, a number of pachinko balls according to the winning value are awarded. The ball is discharged from the prize ball discharging device and flows into the left end of the rear plate 24 from the prize ball port 29. These pachinko balls flow down to the right along the slope of the bottom surface 24a of the rear plate portion 24, and then flow down to the front plate portion 23 side forward due to the inclination of the guide bottom surface portion 24b. And flows into the upstream portion of the front plate portion 23. And
In the front plate portion 23, the pachinko balls flow down to the left along the slope of the bottom surface 23a (in a direction opposite to the flow-down direction of the pachinko balls in the rear plate portion 24). Flow down toward the ball launcher side while aligning in a row.

When there are more pachinko balls discharged as prize balls than pachinko balls fired from the ball firing device, the amount of stored pachinko balls in the front plate portion 23 increases toward the upstream side. Go. Then, when the front plate portion 23 is full, the pachinko balls are sequentially stored in the rear plate portion 24 from the downstream side, and the pachinko balls are stored in a wide storage space expanded behind the pachinko machine. The stored pachinko balls are placed in the front plate 2
3, the pachinko balls on the upstream side flow down to the downstream side in the order according to the above-described route.

In the embodiment described above, the bowl 21 is
It is composed of a front plate portion 23 protruding forward from the front panel 20 and a rear plate portion 24 extending rearward from the front panel 20, and a storage space for pachinko balls is expanded behind the front panel 20, so that more pachinko balls are stored than before. Pachinko balls in one ball dish 2
1 can be stored. In addition, since the pachinko balls can be stored relatively shallowly in the wide storage space expanded backward instead of stacking the pachinko balls high in the ball tray 21, the weight of the pachinko balls is determined by dividing the amount of storage by the downstream side. The back pressure exerted on the pachinko balls can be reduced.

Further, the front plate portion 23 and the rear plate portion 24 are partitioned back and forth by a partition wall 25, and the flow direction of the pachinko balls in the rear plate portion 24 and the flow direction of the pachinko balls in the front plate portion 23 are reversed. As a result, the flow pressure of the pachinko balls in the rear plate portion 24 is effectively prevented from being applied in the downward direction of the pachinko balls in the front plate portion 23, and the amount of stored pachinko balls in the rear plate portion 24 increases. Also, the back pressure applied to the pachinko ball on the downstream side of the front plate portion 23 does not become so large.

Therefore, even if the capacity of the ball tray 21 is increased to increase the amount of stored pachinko balls, the back pressure applied to the pachinko balls on the downstream side is not increased, and the pachinko balls are prevented from forming a bridge. The capacity of the ball dish 21 can be increased without deteriorating the ball flow of the pachinko balls in the ball dish 21, and a large amount of pachinko balls discharged at the time of a big hit can be stored in one ball dish 21. be able to. Further, it is possible to make the conventional two bowls, the upper plate and the lower plate, into one plate, so that the player does not need to transfer the upper plate pachinko balls from the lower plate, and the game board surface can be lowered. This makes it possible to increase the degree of freedom in designing the board surface configuration, and can cope with diversification of the board surface configuration.

If the front plate 23 is made to protrude farther forward than before in order to increase the storage space for pachinko balls, the front plate 23 will protrude toward the player. The player may feel uncomfortable, hit the player's body and disturb the game, and also have a large protruding front plate 2 when the pachinko machine is transported.
3 becomes a hindrance, the packing volume per pachinko machine increases, and the transportation efficiency deteriorates.

In this regard, in this embodiment, the front panel 20
The rear plate 24 is provided at the rear of the front panel 20, and the storage space for the pachinko balls is expanded to the rear of the front panel 20. Therefore, the amount of protrusion of the front plate 23 to the front can be made substantially equal to that of the conventional plate.
The player does not feel uncomfortable, the player's body does not hit the ball tray 21, and there is no adverse effect on the transportation of the pachinko machine.

Further, if the front plate portion 23 and the rear plate portion 24 are partitioned back and forth by the partition wall 25, the state of storage of the pachinko balls in the rear plate portion 24 may be difficult to understand from the player side.
However, in the present embodiment, the viewing window 3 provided on the partition wall 25 is provided.
In addition to mounting the transparent cover 31 on the rear panel 0 and the illuminating light 32 illuminating the rear plate 24, the player can view the window 3
By seeing the inside of the rear plate 24 through the transparent cover 31 of No. 0, it is possible to easily confirm the state in the rear plate 24, such as the presence or absence of the pachinko balls in the rear plate 24, the amount of storage, or the flow of the balls. it can. In this case, the illumination lamp 32 may be turned on only when the amount of stored pachinko balls in the rear plate portion 24 exceeds a predetermined amount.

In this embodiment, the ball dish 21 is made into one dish.
Although the present invention is applied to the above, the present invention may be applied to the upper plate or the lower plate of a pachinko machine having the same two-plate configuration as in the past, so that the capacity of the upper plate or the lower plate may be expanded.

Further, in this embodiment, the ball launching device is provided at the lower left side of the pachinko machine, and the launching ball is launched almost vertically upward from the lower left portion of the pachinko machine. The device may be provided on the lower right side of the pachinko machine, and the shooting ball may be launched almost vertically upward from the lower right side of the pachinko machine.

Further, in the present embodiment, the partition wall 25 for partitioning the front plate portion 23 and the rear plate portion 24 is formed integrally with the front panel 20, but a partition wall formed separately from the front panel is formed on the front panel. The whole partition wall may be formed of a transparent member so that the entire partition wall can be used as a viewing window. Alternatively, the partition wall may be eliminated and the front plate portion and the rear plate portion may be continuous.

In addition, the present invention provides the front plate 23 and the rear plate 2
It goes without saying that various changes can be made without departing from the gist, such as by appropriately changing the shape, board configuration, and the like of No. 4.

[0032]

As is apparent from the above description, according to the pachinko machine of the first aspect of the present invention, the ball plate is provided with a front plate portion protruding forward from the front panel and a rear plate portion protruding rearward. Since the pachinko balls can be stored relatively shallowly in the wide storage space expanded backward, the back pressure that the weight of the pachinko balls exerts on the pachinko balls on the downstream side is reduced, and It is possible to increase the capacity of the ball dish without deteriorating the flow.

In addition, in claim 2, the bottom surface of the front plate portion is inclined downward toward the ball launching device, and the bottom surface of the rear plate portion for receiving the prize ball is inclined downward in the opposite direction to the front plate portion. Then, the pachinko balls in the rear plate portion are caused to flow in the direction opposite to the flow direction of the pachinko balls in the front plate portion, so that the flow pressure of the pachinko balls in the rear plate portion is in the flowing direction of the pachinko balls in the front plate portion. Can be effectively prevented, and even if the amount of stored pachinko balls in the rear plate portion is increased, the amount of back pressure applied to the pachinko balls on the downstream side of the front plate portion can be reduced, and the ball The capacity of the dish can be further increased.
