Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to pinball game machines such as pachinko machines and coin game machines. Specifically, a plurality of obstacle nails are provided on the front surface of the game board, which can change the falling direction of game balls driven into the front surface of the game board, and can be arbitrarily adjusted by the user.
and a variable winning ball device that includes an opening/closing member and can change freely between a first state that is advantageous to the player and a second state that is disadvantageous to the player by opening and closing the opening/closing member. The present invention relates to a pinball game machine that is provided so as to face the surface side of the game board.

[Prior Art] FIG. 2 is a front view of the main part of the game board of a pachinko machine, which is an example of a conventional pinball game machine.

Referring to FIG. 2, a variable winning ball device 12 is arranged in the center of the game board 10, and a starting winning ball receiver 14 is arranged below it. Also, near the left and right sides of the variable winning ball device 12, winning holes 16a and 16b, which are an example of the winning ball device, are provided, and further below, so-called tulips 18a, 1
8b is provided. Further, a large number of obstacle nails 20 are planted on the surface of the game board 10. These obstacle nails 20 are for changing the falling direction of the pachinko balls P falling along the board surface of the game board 10, and from a functional point of view, they are obstacles that prevent the pachinko balls P from entering the winning slot. The role as a thing,
It can be said that it has both the role of a guide member that guides the pachinko balls P to a winning opening, etc.

When a predetermined condition is met, the variable winning ball device 12
The pair of left and right opening/closing members 22a, 22b enters a first state that is advantageous for the player who repeats opening and closing.
It becomes easier for pachinko balls to enter the winning space 24.

In addition, when the variable winning ball device 12 is in the first state, it not only makes it easier for pachinko balls to enter the winning space 24, but also controls the variable winning ball device so that the player can fully enjoy the real thrill of the game. Winning openings 16 provided near both left and right sides of the ball device 12
It is constructed so that pachinko balls can be won relatively easily in a and 16b.

In other words, as shown in FIG. 2, even if the pachinko ball P does not enter the winning space 24, the pachinko ball P that is flipped by the tips of the opening/closing members 22a, 22b, etc.
is designed to make it easier to win into the winning openings 16a and 16b.

Specifically, the array positions and intervals of the obstacle nails 20a and 20b planted in specific areas 26a and 26b on both the left and right sides adjacent to the opening/closing members 22a and 22b are adjusted, and the variable winning ball device 12
is in the first state, the pachinko balls P played by the tips of the opening/closing members 22a, 22, etc. enter the winning opening 16.
This makes it easier to win in a and 16b.

[Problems to be solved by the invention] However, in the conventional pachinko machine, the obstacle nails 20a and 2 planted in the specific areas 26a and 26b are
0b, like the other obstacle nails 20, is a nail that can be freely adjusted by the user, that is, by the pachinko hall, etc., and no special consideration was taken.

For this reason, when designing and manufacturing a pachinko machine, when the variable winning ball device 12 is in the first state, a specific area is set so that pachinko balls can relatively easily enter the winning holes 16a and 16b. 26a, 26
Even if the obstacle nails 20a and 20b of b are adjusted and shipped, there is a possibility that the game content of the pachinko machine could be made to have a completely different feel due to subsequent adjustment of the nails by the user.

To be more specific, since the obstacle nails 20a and 20b in the specific areas 26a and 26b are nails that can be adjusted to any state, by adjusting them, the ball hitting the winning device (winning openings 16a and 16b) can be adjusted. It is possible to make it difficult to win a prize or conversely to make it easier, and when a predetermined condition that allows the variable winning ball device to be in the first state is satisfied once, the number of winning balls generated varies greatly, and The drawback was that the performance of each ball game machine varied greatly.

Therefore, this invention was devised in view of the above-mentioned actual situation, and its purpose is to suppress the variation in the number of winning balls generated when a predetermined condition that allows the variable winning ball device to be in the first state is satisfied. Moreover, the purpose is to prevent the inconvenience that the performance of each pinball game machine differs greatly.

[Means for solving the problem] This invention changes the falling direction of the game balls hit on the front of the game board, and allows the user of the pinball game machine to arbitrarily adjust the falling direction. A book obstacle nail is provided on the front surface of the game board and includes an opening/closing member, and opening and closing of the opening/closing member provides a first state advantageous to the player and a first state disadvantageous to the player. A pinball game machine in which a variable winning ball device that can freely change to a second state is provided facing the surface side of the game board, and when the opening/closing member of the variable winning ball device is opened. A winning ball device that guides the game balls that have collided with the opening/closing member and makes it easier to win a prize, and a winning ball device that is located near the top of the winning ball device and can be arbitrarily adjusted by the user of the pinball game machine, unlike the obstacle nails. It is characterized by the provision of special members that are impossible or difficult to perform.

[Function] According to this invention, when the opening/closing member of the variable winning ball device is opened, the obstacle is placed in the upper vicinity of the winning ball device where the game balls that collide with the opening/closing member are guided and are easier to win. Since the pinball game machine is equipped with a special member other than nails that is impossible or difficult to adjust arbitrarily by the user of the pinball game machine, the user has no control over the winning probability of the winning ball device determined at the time of design and manufacturing. It is possible to prevent arbitrary changes as much as possible.

[Example] Hereinafter, an example of the present invention will be described in detail with reference to the drawings. In the following description of the embodiment, a pachinko machine will be used as an example of a pinball game machine, but it should be noted that this invention can also be applied to pinball game machines such as coin game machines. I would like to point this out for you.

In one embodiment of this invention, in the pachinko machine shown in FIG. 2, the nails provided in the specific areas 26a, 26b are special fixed nails, unlike the normal obstacle nails 20. These fixing nails are directly nailed to the specific areas 26a and 26b of the game board 10, but unlike other obstacle nails, they are made of special material so that they cannot be adjusted or are difficult to adjust after being shipped to the user. Specifically, the nails are made of hard steel that does not bend even when hammered with a nail adjustment hammer, or the nails are thick in diameter and difficult to adjust.

FIG. 1 is a diagram for explaining another embodiment of the fixing nail, and is a cut-away end view of a specific area 26b (see FIG. 2) of the game board 10.

The pachinko machine according to this embodiment has a game board 1 similar to the conventional pachinko machine described with reference to FIG.
0, but only specific areas 26a, 26
The nail planted in b is a special type of nail called a fixed nail.

Referring to FIG. 1, the fixing nail 30 is made of hard plastic such as engineering plastic (for example, DURACON polycarbonate (trade name)).
It is formed of. The fixing nails 30 are not directly driven into the game board 10 like the normal obstacle nails 20, 20a, 20b (see FIG. 2), but are attached to a mounting board 30 that is attached to the surface of the game board 10. The structure has been planted in Fixed nail 3
0 and the mounting board 32 are integrally formed by injection molding or the like.

If the fixing nail 30 is made of such hard plastic, the degree of bending of the nail cannot be adjusted using a so-called nail adjusting hammer, and adjustment in a pachinko hall becomes impossible.

Furthermore, since the fixing nails 30 are embedded in the mounting board 32, the mounting board 32 can be attached to the specific area 26.
A, 26b (see FIG. 2) has the advantage that the fixing nail 30 can be easily and accurately attached to the specific area 26a, 26b.

FIG. 3 is a diagram for explaining still another embodiment of the fixing nail. Fixed nail 34 according to this embodiment
is constructed of steel. The steel material is preferably selected to have a high hardness so that it will not bend even when struck with a nail adjustment hammer or the like.

Fixing nails 34 made of steel are implanted in a mounting board 36 made of hard plastic. That is,
The fixing nails 34 are insert molded when the mounting board 36 is molded from hard plastic.

This configuration has the advantage that, like the embodiment shown in FIG. 1, a plurality of fixing nails 34 can be easily attached by simply attaching the attachment board 36 to a specific area.

Furthermore, when attempting to adjust the fixing nails 34 made of steel, the fixing nails 34 may not deform, or if the fixing nails 34 are hit excessively with a hammer or the like, the hard plastic mounting board 3
6 is cracked, or the fixing nail 34 is damaged by the mounting board 36.
Since the fixing nail 34 may come off, it is almost impossible for the user to adjust the fixing nail 34 by deforming it or the like.

In the embodiment described with reference to FIGS. 1 and 3 above, the mounting board 32 or the mounting board 36 is
The fixed nail 30 or fixed nail 34 is a dedicated one planted in the specific area 26a of the game board 10.
and 26b (see FIG. 2), but the mounting board 32 or 36 on which the fixing nail 30 or 34 is implanted is not a dedicated mounting board,
The mounting board 38 (see FIG. 2) of the variable winning ball device 12 is widely installed on both the left and right sides, and the variable winning ball device 12
A fixing nail 30 or 34 may be planted in the wide part of the mounting board 38. That is, the mounting board 38 of the variable winning ball device 12 and the mounting board 32 or 36 of the fixed nail 30 or 34 may be made into an integrated mounting board.

In this way, there is an advantage that the positional relationship between the variable winning ball device 12 and the fixed nails 30 or 34 located on both sides thereof will not be disturbed.

FIG. 4 is a partial front view of the game board 10 of a pachinko machine according to another embodiment of this invention.

In FIG. 4, 40a and 40b are specific areas, and the nails formed in these areas are the special fixed nails 30 mentioned above.

To explain in more detail, in the embodiment shown in FIG. 4, the variable winning ball device 42 has a horizontally long opening 46 formed in the mounting board 44, and the opening/closing member 4 is inserted into the opening 46.
8 are fitted, and by opening and closing the opening/closing member 48, the variable winning ball device 42 changes to a first state that is advantageous to the player or a second state that is disadvantageous to the player. . Then, the opening/closing member 48 opens forward to receive the pachinko balls P falling from above, and the pachinko balls P enter the opening 4 as a winning area.
6, the pachinko balls _P2 that collide with both ends of the opening/closing member 48 are made to easily enter prize openings 50a and 50b provided diagonally downward on the left and right within a certain probability range. , fixed nail 3
0 has been adjusted. Due to the above-described configuration, the fixing nail 30 is impossible or difficult to adjust by the user after shipping.

In addition, in the explanation of FIG. 4, the fixing nail 30 is
Although the description has been made assuming that the fixing nail 34 is made of resin as explained with reference to the figures, it goes without saying that it can be replaced with the fixing nail 34 of the embodiment explained with reference to FIG. 3 or the fixing nail of other embodiments. .

In each of the above embodiments, the fixed nails are provided close to the left and right sides of the variable winning ball device. Mouth 16a,
Of course, depending on the positional relationship with the fixing nail 16b, the location where the fixing nail should be installed may be moved vertically or horizontally, or its range may be wide or narrow, as necessary. These winning holes 16a and 16b constitute a winning ball device in which game balls that collide with the opening/closing member of the variable winning ball device are guided when the opening/closing member of the variable winning ball device is opened, making it easier to win.

Further, the variable winning ball device is not limited to the two types described above, and may be of other types.

[Effect of the invention] As described above, this invention provides an upper part of the winning ball device in which the game balls that collide with the opening/closing member of the variable winning ball device are guided when the opening/closing member of the variable winning ball device is opened, making it easier to win. Because a special member that is impossible or difficult to arbitrarily adjust by the user of the pinball game machine, unlike the obstacle nail, is installed nearby, the ball cannot be hit when the variable winning ball device is in the first state. It is possible to suppress variations in the probability of winning a prize to the winning ball device, prevent variations in the number of winning balls generated when a predetermined condition for the variable winning ball device to be in the first state is established, and improve gaming performance. It is possible to provide a homogeneous pinball game machine.
