BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a ball game machine,
In particular, it has a winning opening provided in the game area and a warp mechanism adapted to guide the gaming ball to the winning opening after taking in the game ball launched into the playing area. It relates to a ball game machine.

[0002]

2. Description of the Related Art Conventionally, as a ball game machine, for example, a pachinko game machine, a game ball shot into a game area is temporarily taken in, and then the game ball is placed in a winning opening provided in the game area. There is known a mechanism including a so-called warp mechanism that is guided upward and flows down toward the winning opening.

This warp mechanism is opened in the middle of the dropping path of the game ball in the game area, and guides the game ball taken in and the game ball taken in the guide port above the winning opening. And a taxiway. Then, in this warp mechanism, the game balls shot in the game area randomly jump into the guide port to take in the game balls, whereby the game balls are once hidden from the game surface. After that, the game ball is guided by the guide path to a visible position above the winning opening, and then dropped from the guide path toward the winning opening.

In a ball-and-ball game machine provided with such a warp mechanism, the game ball once disappears and then reappears, and the flow of the game ball is such that a mountain nail or a nail standing upright on the game surface. The flow will be different from the normal flow due to valley nails, loose nails, or side nails, the diverging route will be diversified, and the expectation of winning will be increased by guiding the game ball above the winning opening. By doing so, it is possible to bring out games with a lot of interest.

[0005]

By the way, it has become possible to bring out an interesting game by using the above-mentioned conventional ball game machine equipped with the warp mechanism. There are still problems to be improved.

That is, the above-mentioned conventional warp mechanism is
Guidance from the game ball up to above the winning opening,
Since the route to the prize hole is fixed, depending on the type of warp mechanism, the model with a high probability of winning the game ball guided by this warp mechanism and the model with a low probability of winning. There is a problem that it tends to be divided into and, and that the adjustment of the winning probability is difficult except for the nail adjustment.

[0007] If the model is easy to win, the number of prize balls discharged against the prize balls becomes too large, and the profit balance between the player and the game store cannot be balanced. If you make nail adjustments that are difficult to win, and if the model is difficult to win, despite the existence of the warp mechanism, that function is not fully utilized, so the interest of the game is halved. Resulting in.

[0008] In particular, if the winning port is a specific winning port for generating a right to shift to a specific game mode, the probability of the above-mentioned right is lowered, and the interest of the game is further impaired. I will end up.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a ball-playing machine having a warp mechanism capable of easily changing the winning probability to a winning opening. And

It is characterized in that it is provided with a distribution tray which can be rotated between two positions, that is, a position where it is sent to one of the guideways and a position where the game ball is passed and dropped to another guideway.

According to a third aspect of the present invention, in the ball game machine according to the second aspect, the flow path changing means in the ball game machine is provided with a drive mechanism for reciprocally rotating the distribution tray within a predetermined angle range. It is characterized by being

In the ball-ball game machine according to claim 4, each discharge path in the ball-ball game machine according to claim 1 is formed to have a different width, and the flow-down area width of the game ball with respect to the winning opening is made different. Thereby, the winning probability of the game ball to the winning opening is changed by each discharge path.

Further, in the ball-playing machine according to claim 5, the winning opening in the ball-playing machine according to claim 1 causes the right to shift to a specific game form different from the normal game form. It is characterized by being a winning opening.

[0015]

In the bullet-ball game machine according to the first aspect, when a game ball is launched into the game area, the game ball is randomly taken into the guide port of the warp mechanism and is taken into the warp mechanism. The game ball taken into the warp mechanism is first sent to one guide path selected by the flow path changing means, and is guided to above the winning opening along the selected guide path, The discharge passage formed in the guide passage causes the discharge passage to flow down toward the winning opening.

The probability of winning a game ball flowing down to the winning opening through the discharge path is determined by the discharging path, and the discharging path is provided in each of the plurality of guide paths. In addition, since the winning probability is different for each discharge path of each guide path, the guide path into which the game ball is sent can be arbitrarily switched by the flow path changing means, so that the winning probability to the winning opening can be easily made. Be changed.

In the ball-and-ball game machine according to the second aspect, the guide path into which the game ball is fed is selected depending on the rotating position of the distribution plate.

In the ball-and-ball game machine according to the third aspect of the present invention, the guide path can be changed by an external operation by rotating the sorting plate by the drive mechanism.
For example, during the game, it is possible to adjust the winning probability according to the game state.

Further, in the ball game machine according to claim 4, since the discharge paths of the respective guide paths are formed to have different widths, the game balls guided to the narrow discharge path are in the downward direction. It is made to flow down toward the winning opening in a narrow range in the width direction, and the winning probability is increased. Further, the game ball guided to the wide discharge path has its flow-down direction varied by the width of the discharge path, and as a result, the winning probability to the winning opening is lowered.

Further, in the ball-ball game machine according to the fifth aspect, when the game ball wins the specific winning opening, the right to shift to the specific game form is generated. Therefore, the warp mechanism easily changes the winning probability to the specific winning opening, so that the right to shift to the specific game mode described above is appropriately generated.

As shown in FIG. 2, the motor 23 and the photo sensor 26 of the position detecting mechanism 24 are provided with a base plate 28 on a plurality of supporting legs 27 projecting from the rear surface of the frame 9. Is attached through.

Further, in the present embodiment, the maximum number of times the variable display game that can be started by the game ball B that has won the specific winning opening 5 can be started on the upper front surface of the frame 9 is four times. A storage means 29 for storing and displaying the limit is provided, and the guide port 11 is provided above the storage means 29.
An auxiliary variable display device 30 is provided which starts a variable display game on condition that the passage of the game ball B in the guide port 11 is detected by the game ball detection sensor 12 provided corresponding to. In the auxiliary variable display device 30, when the display form at the time of stop is a specific display form, for example, "1", "3", "5", "7", etc., the specific winning opening 5 is The open state is maintained for a set time, for example, 5 seconds.

Further, in the present embodiment, a display unit 31 for displaying the number of operations of the special variable winning device 6, that is, the number of times the special game mode is continued is provided below the special variable winning device 6.

Then, the special variable display device 3, the specific winning opening 5, the special variation winning device 6, the game ball detection sensor 1
2, the flow path changing unit 18, the storage unit 29, the auxiliary variable display device 30, the display unit 31 and the like are controlled by a control unit (not shown) provided at the rear of the game board 1. There is.

Next, the operation of this embodiment thus constructed will be described. When the game ball B is shot above the game area G by the launch device operated by the player, the game ball B falls downward in the game area G while following a random flow-down path.

Then, some of these game balls B directly enter the specific winning opening 5 from around the warp mechanism 4,
Also, some game balls B are the guide ports 1 of the warp mechanism 4.
It is taken into the inside from 1.

When the game ball B is thus taken into the warp mechanism 4, the game ball detection sensor 12 detects the passage of the game ball and the auxiliary variable display device 30 starts the auxiliary variable game based on the detection result. When the display form in the game result becomes the above-mentioned specific display form, the specific winning opening 5 is opened for a predetermined time,
The winning probability to the specific winning opening 5 is increased. In addition, in the case of a display form other than the specific display form, the specific winning opening 5 is kept closed and the normal winning probability is held.

When a prize is paid to the specific winning opening 5, the right to shift to a special game form is generated, and the variable display game on the special variable display device 3 is started.
When a prize is further awarded to the specific winning opening 5 during the variable display game, the aforesaid right is generated by this award, but this right is a predetermined upper limit (4 in this embodiment). The number of times is stored within a range not exceeding the number of times, and the number of times is displayed in the storage means 29.

Then, when the variable display game on the special variable display device 3 is started and the stop display form as a result of the game becomes a specific display form, the special variable winning device 6 is operated, so that the player The game is shifted to an advantageous specific game mode in which the game ball B is easy to win. This game mode ends when the number of winning balls to the special variation winning device 6 reaches a predetermined number (for example, 10), but this is defined as one cycle and is provided in the special variation winning device 6. The game is finished after a predetermined cycle (for example, 15 cycles) is continued on condition that the winning of the continuous winning opening is continued.

On the other hand, in the game ball B taken into the warp mechanism 4, the distribution plate 21 of the flow path changing means 18 is the first.
When it is held at the position (hereinafter, this state is referred to as the first state), as shown in FIG. 4, it is dropped from the guide port 11 directly to the upstream end of the first guide path 13, As shown by the arrow in the figure, while rolling on the first guide path 13,
It is guided to a wide discharge passage 15 formed in the central portion of the first guide passage 13, and is made to flow down from the discharge passage 15 toward a specific winning opening 5 provided below the discharge passage 15.

Here, the discharge passage 15 formed in the first guide passage 13 is formed wide as described above, and the game ball B taken into the warp mechanism 4 is
Due to the difference in the momentum and rotation when entering the guide port 11, the momentum of the game ball B rolling in the first guide path 13 is different, so that this game ball B is in the discharge path 15 and is indicated by an arrow in FIG. As shown by, the flow path will vary in the width direction. Then, the momentum of the game ball B is appropriate, and when the game ball B enters the guide groove 17 formed in the discharge path 15, the game ball B is directly above the special winning opening 5 by the guide groove 17. However, the game balls B other than this are flown down to the side of the special winning opening 5, and the winning is not made. Therefore, the winning probability of the game ball B dropped into the first guide path 13 to the specific winning opening 5 is low.

Further, the distribution plate 21 of the flow path changing means 18
When is located at the second position (hereinafter, this state is referred to as the second state), the game ball B passed through the game ball detection sensor 12 is, as shown in FIGS. 3 and 4, After being captured by the ball receiving portion 21a of the sorting plate 21, it is sent to the guide portion 21c through the through hole 21d, and is dropped to the upstream end of the second guide path 14 by this guide portion 21c. In the present embodiment, the turning of the sorting tray 21 to the second position is performed by the drive mechanism 22 which is operated by a signal from the control means, and the motor 23 is driven by this signal to drive the sorting tray. The rotation of the motor 21 is started, and the driving of the motor 23 is stopped when the detection piece 25 attached to the rotation shaft 20 is detected by the photo sensor 26.

The game ball B guided to the second guide path 14 in this way is rolled on the second guide path 14 toward the central portion, and is formed on the second guide path 14. This discharge path 1 is dropped into the narrow discharge path 16 and
By means of 6, it is made to flow down to the guide groove 17 of the first guide path 13. Since the discharge path 16 is formed to have a width substantially equal to the diameter of the game ball B, the flow-down path of the game ball B guided and flowed down by the discharge path 16 is shown by an arrow in FIG. So, it becomes almost one system,
It is surely guided to the guide groove 17 and the guide path 1
As described above, the game ball B guided to 7 has its lateral vibration suppressed, and is almost certainly won into the specific winning opening 5. Therefore, most of the game balls B guided to the second guide path 14 are made to win the specific winning opening 5, and the winning probability thereof is greatly increased.

As described above, in this embodiment, the winning probability of the specific winning opening 5 can be easily changed and can be changed without adjusting the nails. In addition, the drive mechanism 2
By 2, it is possible to change the winning probability even during the game, and it is possible to easily diversify the game conditions.

On the other hand, in the present embodiment, the change of the winning probability by the drive mechanism 22 is performed under the following program, for example.

(1) In the state where the variable display game result on the special variable display device 3 becomes a specific display form and the game form is shifted to the specific game form, the flow path changing means 18 is set to the second state, The second state is maintained until the display form of the variable display game becomes the specific display form again. As a result, it is possible to increase the winning probability of the specific winning opening 5 after the special game form is finished, and increase the occurrence probability of the next special game form.

(2) It is operated in association with the auxiliary variable display device 30. That is, when the result of the variable display game of the auxiliary variable display device 30 has a specific display form, the specific winning opening 5 is opened to increase the winning probability in the above description. Furthermore, the auxiliary variable display device 30 sets the flow path changing means 18 to the second state for a predetermined time with respect to some display forms of this particular display form, for example, "3" and "7". is there. This not only aims to diversify the game form, but also when the specific winning opening 5 is opened, the game ball B in the game area G
There is a case where the player does not win due to the downflow route of the game or the timing of reaching the special winning opening 5, but the game ball B guided to the special winning opening 5 via the warp mechanism 4 in the second state is almost certainly won. Therefore, it is a procedure for increasing the winning probability. In this case, the specific winning opening 5 is open,
Alternatively, it can be set to either closed state.

(3) When the number of times the variable display game that can be started by the game ball B that has won the specific winning opening 5 can be started is zero, that is, when there is no storage in the storage means 29, the flow path changing means. 18 is in the second state. As a result, the winning probability for the specific winning opening 5 is increased,
The number of starts of the variable display game is set as the appropriate value.

(4) The flow path changing means 18 is periodically set to the first
The state is switched to the second state. Thereby, the winning probability to the specific winning opening 5 is adjusted to an appropriate value.

As described above, according to the bullet-ball game machine according to this embodiment, the game ball B taken into the warp mechanism 4 is guided by the flow path changing means 18 to the first guide path 13 and the second guide path 1.
These taxiways 13.1 after being assigned to
It is made to flow down toward the specific winning opening 5 by the discharge passages 15 and 16 formed in 4, and these discharge passages 15 and 16 are formed.
When the water is made to flow down, the flow-down path is
・ By making different downflow routes in 16,
The winning probability to the specific winning opening 5 by the warp mechanism 4 is changed.

Therefore, since the winning probability to the specific winning port 5 is changed only by operating the flow path changing means 18 in the warp mechanism 4, the operation is easy.

Moreover, in the present embodiment, since the operation of the flow path changing means 18 is performed by the drive mechanism 22, for example, the winning probability to the specific winning opening 5 is adjusted according to the situation of the game. As a result, it is possible to adjust the profit balance between the player and the game store without impairing the interest of the game.

Since the mechanism for adjusting the winning probability has a structure in which the widths of the discharge paths 15 and 16 are made different, the structure is simple, reliable operation can be obtained, and the production is easy. is there.

Furthermore, in the present embodiment, the winning opening whose winning probability is adjusted by the warp mechanism 4 is the specific winning opening 5 as the starting opening for starting the variable display game on the special variable display device 3. Therefore, the start probability of the variable display game is adjusted to an appropriate value, and a game with rich interest is realized.

It should be noted that the shapes and sizes of the respective constituent members shown in the above embodiment are merely examples, and can be variously changed based on the type of ball game machine to be applied, design requirements and the like. For example, in the above-mentioned embodiment, an example in which two taxiways are provided has been shown, but the invention is not limited to this, and three or more taxiways may be provided. Also, the flow path changing means 18 has been shown as an example of the distribution plate 21 that can be moved forward and backward below the guide port 11, but instead of this, the game is always positioned below the guide port 11 and is taken in. It is also possible to use a flow path changing means configured to constantly capture the sphere B and distribute it to a plurality of guide paths. Further, although the specific winning port is exemplified as the winning port, it is of course possible to apply to the general winning port.

[0062]

As described above, according to the first aspect of the present invention.
According to the ball game machine described, the game balls taken into the warp mechanism through the guide port are distributed to the plurality of guide paths by the flow path changing means, and formed in each of these guide paths. Since it is made to flow down toward the winning opening by the discharge path forming the flow-down path, the winning probability can be changed only by selecting the guide path into which the game ball is fed by the flow path changing means. , As a result, you can change the winning probability without adjusting the nails,
The operation can be simplified.

According to the ball-ball game machine of the second aspect, the flow path changing means is arranged below the guide port, and the game ball taken from the guide port is captured and sent to one of the guide paths. By configuring the position and the rotatable distribution plate that allows the game ball to pass and fall to another guide path, the flow path changing means can be made a simple structure and its operation can be ensured. , Can make production easier.

According to the ball game machine of the third aspect, the distribution probability constituting the flow path changing means is rotationally driven by using the drive mechanism so that the winning probability is changed. It is possible to change the winning probability by a manual operation, and thus, for example, by changing the winning probability in accordance with the game situation during the game, the profit of the player and the gaming shop is balanced. However, the game can be made more interesting.

According to the ball game machine of claim 4, the discharge path formed in each guide path is changed to the flow path of the game ball by changing the width of the flow-down area with respect to the winning port of the game ball. As a result, the winning probability of the game ball to the winning opening is changed, so that not only the function of changing the winning probability can be realized with a simple configuration but also the production can be facilitated.

Further, according to the ball-playing machine according to the fifth aspect, the winning opening whose winning probability is adjusted by the warp mechanism is a specific winning opening for generating the right to shift to a specific game form. It is possible to increase the interest of the game by making the probability of the right occurrence appropriate.
