Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine typified by a pachinko game machine and the like, and more specifically, it is provided in a game area where a ball is hit and is advantageous to a player.
The present invention relates to a ball game machine having a variable winning ball device that can be changed to a second state that is disadvantageous to the player.

[0002]

2. Description of the Related Art In this type of ball game machine, a variable winning ball device is advantageous to a player, which is generally known in the art, for example, based on a predetermined game state. There is a game machine which is configured so that a relatively large number of hit balls can win the prize and provide a great game value to the player.

[0003]

However, in the conventional variable winning ball device of this kind, if a hit ball is won in the variable winning ball device in the first state, it will be the one winning ball. On the other hand, since the game value of a predetermined size can be uniformly given, the player's concern is that the variable winning ball device is once switched to the first state. There is a drawback that the variable winning ball device only makes a hit or not, resulting in a less interesting game with little change.

Therefore, in the variable winning ball device, a relatively small value can be imparted by passing through a specific area defined so that a relatively large value can be imparted by passing an impact ball. Even if the hit ball has entered the variable winning ball device, the value of the value that can be given differs depending on whether the ball passes through the specific area or the normal area. It is conceivable that, even after the hitting ball enters the variable winning ball device, the value is varied depending on the area where the hitting ball passes to improve the variability of the game. However, even in the case of such a configuration, for example, when the specific area is biased to one corner in the variable winning ball device and a plurality of normal areas are arranged only on the opposite side of the specific area, the variable winning ball is arranged. If the batting ball that has entered the device is flowing down the side where the specific area is provided, it is highly likely that it will pass through the specific area, but the batting ball will flow down the opposite side where the specific area is not provided. If it is, the probability that the batting ball will pass to the specific area will be low, and it will be possible to judge whether to pass the specific area early depending on the position where the batting ball has flown before passing the specific area. Therefore, there is a drawback in that it is difficult to leave the expectation that a hit ball that has entered the variable winning ball device may pass through a specific area to the player as long as possible.

The present invention has been conceived in view of the above circumstances, and its purpose is to determine which area the hitting ball passes even after entering the hitting ball or the variable winning ball apparatus. The value that can be granted is changed to make the game variable, and the player expects the ball hitting into the variable winning ball device to pass through a specific area for as long as possible. It is to provide a variable winning ball device that can do.

[0006]

The present invention is provided in a game area where a ball is hit, and can be changed into a first state which is advantageous to the player and a second state which is disadvantageous to the player. A ball game machine having a variable winning ball device,
A specific area that is formed in the variable winning ball device and is determined so that a relatively large predetermined value can be imparted by passing a ball that has entered the variable winning ball device, It is provided on both sides of the area, and includes a normal area defined so that a relatively small predetermined value can be given by passing a ball hitting the inside of the variable winning ball device. And

[0007]

According to the present invention, if a ball hitting the inside of the variable winning ball device passes through a specific area, a relatively large predetermined value can be given, and a ball hitting the inside of the variable winning ball device can be provided. A relatively small value can be added when passing through the normal area, and the value that can be added differs depending on which area the pachinko ball that has entered the variable winning ball device passes. Moreover, since the normal areas are provided on both sides of the specific area, it is difficult to predict whether the hit ball entering the variable winning ball device will pass through the specific area or the normal area.

[0008]

Embodiments of the present invention will now be described in detail with reference to the drawings.

FIG. 1 and FIG. 2 are schematic views of a variable winning ball device 30 provided in a game area of a ball game machine of the present invention. In particular, FIG. 1 is a perspective view thereof, and FIG. 2 is an example of a specific winning area 3 that is an example of a specific area defined so that the variable winning ball device 30 can be repeatedly opened and closed by passing a ball.
It is a longitudinal cross-sectional view of 2a.

Next, referring to FIG. 1, a variable winning ball device 3
A specific configuration of 0 will be described. Decorative frame 3 as an example of a mounting plate
In the central portion of 1, there is formed a through hole serving as a winning area 32 in which a hit ball can be won. An opening / closing plate 33 is provided on the front surface of the through hole so as to be openable on the front surface side. A lower side of the opening / closing plate 33 is pivotally supported by a shaft 332, and a U-shaped protrusion 331 is formed on the back surface of one side (right side in the drawing) of the opening / closing plate 33. A through hole is formed in the protrusion 331. The pin 341 fixed to the tip of the lever 34 is inserted through the through hole. The other end of the lever 34 is supported by a fulcrum 342. At an upper position of the lever 34, an opening / closing mechanism 35 as an example of a driving unit for driving the opening / closing plate 33 to open / close is provided. The opening / closing mechanism 35 includes a solenoid 351, and one end of a rod 353 is connected to a plunger or 352 of the solenoid 351.
The other end of 3 is connected to the central portion of the lever 34.

The winning area 32 is composed of a plurality of areas 32a, 32a.
It is divided into b and 32c. Of these, the balls that have won the winning areas 32b and 32c, which are an example of the normal area, are guided to the back surface as they are (without driving any member of the variable winning ball device 30). Then, the variable winning ball device 30 flows out to a predetermined path of the pachinko gaming machine to which the variable winning ball device 30 is attached.

On the other hand, in the winning area 32a formed in the center of the winning area 30, a specific winning area is defined so that the opening / closing plate 33 of the variable winning ball device 30 can be repeatedly opened and closed according to the passage of a ball. Area. That is, the specific winning area 32a is an area that can be given a relatively large value that the opening / closing plate 33 of the variable winning ball device 30 can be repeatedly opened and closed. The configuration and operation therefor will be described in detail later.

Safe holes 36a and 36b are formed in the decorative frames 31 on both sides of the winning area 32. These safe holes 36a, 36b are formed so as to project to the front side with respect to the surface with the decorative frame 31 so that the pachinko balls falling along the game board from above can always be received.

Next, the operation of the variable winning ball device 30 of this embodiment will be briefly described. The opening / closing plate 33 is a solenoid 35.
When 1 is urged and the plunger 352 is pulled up, it is opened as shown in FIG. 1, and the winning area 32 is opened. On the contrary, when the solenoid 351 is deenergized, the plunger 352 is pushed downward by the force of the return spring, so that the lever 34 is rotated downward and the opening / closing plate 33 is closed, so that the winning area 32 is formed. To be closed.

Next, referring to FIG. 2, the specific winning area 32
The details of a will be described. As described above, the specific winning area 32a receives balls when the opening / closing plate 33 is opened to the front side, and opens the opening / closing plate 33 again when a hit ball wins while the opening / closing plate 33 is opened. This is a defined winning area. Therefore, it is necessary to detect a ball that has won the specific winning area 32a by some detecting means. As a generally known means for detecting a pachinko ball, there is a micro switch, a detector for detecting a magnetic flux density or an electrostatic capacity which changes with the passage of a ball, or a photoelectric sensor.

On the other hand, there is a demand to use the game area of the game board as effectively as possible, and in order to meet the request, the variable winning ball device 30 is located at the lower position of the game board (as a matter of course, the out ball entrance). It is desirable to have a configuration that can be disposed above (albeit above). However, when the variable winning ball device 30 is provided below the game board, the known ball detecting means as described above has a too large mounting place and cannot be spatially mounted in relation to the out ball entrance. There was a drawback that it became.

Therefore, in this embodiment, the specific winning area 3
The balls that have won the prize 2a will be detected by the detecting means configured as follows.

That is, referring to FIG. 2, below the back surface of the specific winning area 32a, there is a path 37 which is inclined obliquely downward.
Are formed. In the notched part of this path 37,
The ball detection member 38 is rotatably mounted. The ball detection member 38 has a shape in which two V-shaped pieces 381 and 382 are combined, and a joint portion thereof is pivotally supported by a shaft 383. Further, in the ball detection member 38, one side of the V-shaped member 381 is normally inserted in the path 37 as shown by the solid line in the figure. In this state, when the pachinko ball wins the specific winning area 32a and passes through the path 37, the V-shaped member 381 is pressed counterclockwise. The pressed state is
It is indicated by a dashed line.

A photo coupler 39 is provided at an upper position of the V-shaped piece 382 when the ball detection member 38 is most pushed out by the passage of the pachinko ball. The photocoupler 39 includes a light emitting unit and a light receiving unit, and the light receiving amount of the light receiving unit differs depending on whether the V-shaped pieces 382 are closest to each other or not, and a passing ball is detected by a change in the light receiving amount. To do.

The ball detection member 38 is made of a resin material, and the V-shaped piece 382 facing the photocoupler 39 has:
In order to improve the reflection of the light of the light emitting portion, a reflection plate 384 having a glossy surface plated with aluminum plate, aluminum paper, stainless thin plate or thin iron plate is attached.

As another member for detecting passing balls,
A so-called magnet sensor using a reed switch in place of the photocoupler 39 and a permanent magnet in place of the reflection plate 384 can also be used.

3 to 5 are schematic views showing another example of the variable winning ball device. In particular, FIG. 3 is a perspective view of another example of the variable winning ball device as viewed from the front, FIG. 4 is a view of the device as viewed from the back, and FIG. 5 is a vertical cross-sectional view showing an opened state of the opening / closing plate. It is a figure.

Referring to FIGS. 3 to 5, the variable winning ball device 40 of this embodiment has three rectangular through holes formed in the vertical direction of the decorative frame 41 and separated by a certain distance. ing. Each through hole is a winning area 42a, 42b, 42c. Opening / closing plates 43a, 43b, 43c are mounted on the front surfaces of the winning areas 42a, 42b, 42c so as to be openable / closable. The winning area 42a is a specific area conditioned in the same manner as the specific winning area 32a of the first embodiment described above. More specifically, a frame member 44 is formed on the back side of the decorative frame 41. The frame member 44 has a U-shape when viewed from above and is formed to be long in the vertical direction (vertical direction).
The partition plate 441 is formed only on the back surface portion of 2a, and the back surface portions of the normal winning regions 42b and 42c are formed in communication with each other, and the lower portion thereof is an opening. And the specific winning area 4
The frame member 44 on the back side of 2a is provided with a through hole 442 for guiding the balls that have passed through the specific winning area 42a to the back side. Below the through hole 442, a detection switch 46 for detecting a pachinko ball winning in the specific winning area 42a is provided.

Triangular protrusions 431 and 432 are formed on both sides of the respective back surfaces of the opening / closing plates 43a, 43b and 43c. A shaft is formed on each of the protruding pieces 431 and 432 on both sides of each of the opening / closing plates 43a to 43c, and is pivotally supported by the side wall of the frame member 44. Further, a rod 434 is fixed to the tip of the shaft of the projection piece 431 on one side of each opening / closing plate. In association with each rod 434,
An opening / closing mechanism 4 for opening / closing driving the opening / closing plates 43a to 43c.
5 are provided. The opening / closing mechanism 45 includes each opening / closing plate 43a.
To 43c, a slide plate 454 that is slidable on the side wall of the frame member 44 and is linked to the rod 434, and the pin formed on the slide plate 454 is connected to the plunger 452 of the solenoid 451.
It is configured to be linked to the rod 453 connected to the.

Then, by electrically energizing the solenoid 451, the sliding plate 454 is pulled upward, and thereby the rod 4 linked to the sliding plate 454 is pulled up.
34 is rotated and the opening / closing plates 43a to 43c are opened to the front side. On the other hand, when the solenoid 451 is deenergized, the plunger 452 is pushed out and the sliding plate 454 is pushed down, whereby the opening / closing plates 43a to 43c are closed.

In the two variable winning ball devices 30 and 40 described above, the relatively large value given when the pachinko balls are won in the specific winning regions 32a and 42a is the opening / closing plate 33 or 43a, 43b, 43c. Has been described as being opened again. However, the relatively large value is not limited to the above-mentioned value, and may be, for example, to give again a start condition for controlling the opening / closing of the opening / closing plate of the variable winning ball device 30 or 40. Specifically, when the variable winning ball device 30 or 40 is opened in a specific display state of a variable display device such as a rotating drum display mechanism, the gaming value of rotating the rotating drum display mechanism or the like again is given. It may be one.

Alternatively, the relatively large value may be a game value of opening another winning ball device, for example, a yakmono called a tulip.

Further, in each of the above-mentioned embodiments, the variable winning ball device has the opening / closing plate as the opening / closing member.
It should be added that the opening / closing member may be, for example, a variable winning ball device that is an opening / closing member that opens and closes a pair of blades (movable pieces) of a so-called airplane type.

[0029]

According to the present invention, since the amount of value that can be given is different depending on whether the ball hitting the inside of the variable winning ball device passes through the specific area or the normal area,
It is possible to provide the player with a variety of games even after the hit ball has entered the variable winning ball device. Moreover,
Since normal areas are provided on both sides of the specific area, it is difficult to predict which area the ball hitting the variable winning ball device will pass, and the ball hitting the variable winning ball device is difficult to predict. It is possible to make the player feel the expectation that the character may pass through a specific area for as long as possible.
