In addition, a middle symbol starting port 14c is configured. In addition, each symbol start
A pair of nails are provided directly above the mouths 14. In addition, even if a hit ball flows into each of these symbol starting ports 14, if the symbols are changing or the variable winning device 15 is open, the changing of the symbols cannot be started, so the starting port switch 68 is turned on. Then, it is set so that a maximum of four such balls can be stored, and the storage indicator 31 is turned on. Then, after the symbol change is stopped or after the opening operation of the variable winning device 15 is completed, the symbol change is started again, and at the same time, the number of lighting of the storage indicator 31 is reduced by one.

The variable prize winning device 15 that forms a large winning opening that can be converted into a first state that is disadvantageous to the player and a second state that is advantageous to the player may have any configuration, but in the embodiment shown in the drawings, The so-called attacker is configured to open and close a gate plate 70 having a lower edge side pivotally supported by a horizontally long winning opening 69 using a solenoid or the like as a drive source. The variable winning device 15 has a specific area 71, a continuation switch 72 for detecting a ball passing through the specific area 71, and a 10-count switch 73 for detecting all the balls winning the special winning opening. Is provided.

Next, the game of the pachinko machine 1 having the above configuration will be described. In the pachinko machine 1, the drive motor 46 of the ball guiding means 24 rotates when the power is turned on, and the open / close arm 47 makes one reciprocation. It opens and closes in 8 seconds, and the special symbol display device 12 scrolls the model name. Further, in this pachinko machine 1, when a hit ball hit by a player wins a variable winning device 15 which is a large winning opening, 15 hits per winning ball.
When a prize ball is paid out and another prize-winning tool 17 or a symbol starting port 14 is won, seven prize balls are paid out per one prize ball.

The hit ball hit by the player is the center role 13
When the ball flows into the prize winning opening 36 which is the ball entrance 23a of the ball , through the ball guiding gutter 41, the opening / closing arm 4 which is the ball guiding means 24
Fall between seven. Then, depending on the state of the opening / closing arm 47, it flows down on the bottom plate 43 of the center item 13 as it is, is temporarily suspended, or the course is changed. Then, after being temporarily held, the ball released from the opening / closing arm 47 flows down the center of the bottom plate 43, and
The probability of flowing into the middle symbol starting port 14c disposed immediately below the third symbol is increased. The functions of the right symbol starting port 14r and the left symbol starting port 14l are the same as those of the middle symbol starting port 14c, and the symbol starting ports 14 may be aimed at depending on the preference of the player.

When a ball flows into the symbol starting port 14 and the starting port switch 68 is operated, the symbol display section 25 of the special symbol display device 12 starts to display the variation of the symbol. It is to be noted that, for example, 15 types of symbols can be displayed on each symbol display section 25. And the special symbol display device 12
When the set time has elapsed since the start of the variable display of symbols, the variable display stops in the order of the left symbol display section 25l, the right symbol display section 25r, and the middle symbol display section 25c. At this time,
The fluctuation speed of each symbol display section 25 is set to a different speed, and is set so that the fluctuation speed changes immediately after the start of the fluctuation, before the stop, and between them.

When the symbols stopped and displayed on the symbol display sections 25 are in a predetermined combination mode, a "big hit" is established, and the large winning opening of the variable winning device 15 is opened for about 30 seconds. When ten hit balls flow into the winning opening 69 of the variable winning device 15, the gate plate 70 returns and turns to close the winning opening 69 even before 30 seconds have elapsed.

When the hit ball passes through the specific area 71 and the continuation switch 72 is turned on while the variable prize winning device 15 is being opened, the opening operation is terminated and a new opening operation is started. The number of times the winning opening 69 is continuously opened is set to 16 times including the first opening. In addition, the number of times of continuation opening is displayed on the right symbol display section 25r during opening of the special winning opening.

In the pachinko machine 1, in response to the operation during the game, the status at that time is visually displayed by each of the indicator lamps 18... And the player is notified by sound effects.

According to the pachinko machine 1 having the above-described configuration, the player only has to aim and shoot the vicinity of the winning hole 36 of the center role 13, and the aim is easily narrowed. Then, when the ball enters the world winning hole 36, the ball falls through the ball guiding gutter 41 onto the bottom plate 43 of the center role 13, where the ball guiding means 2
4 That is, if the opening / closing arm 47 is open, it flows down while maintaining the same flow path, and if the opening / closing arm 47 is closed, it temporarily stops at the center of the bottom plate 43 and the opening / closing arm 47 is opened. In addition, since the ball flows down the center of the bottom plate 43, the probability of entering the middle symbol starting port 14c located immediately below is increased. Therefore, even if the nail adjustment near the world winning opening 36 is performed, the winning rate of the middle symbol starting opening 14c does not directly change, so that the nail adjustment becomes easy. Moreover,
The winning rate of the world winning port 36 can be increased to improve the player's sense of expectation.

FIG. 7 shows another embodiment of the ball guiding means 24. In this embodiment, a guide rib 74 is provided on the bottom plate 43 of the center part 13 where the exit of the ball guiding gutter 41 faces. A rotating member 75 that is rotated by a motor (not shown) is provided while preventing a ball falling from the air from diffusing. The rotating member 75 has, for example, a cylindrical shape,
A flow path changing portion 76 for changing the flow path is formed on the peripheral surface. According to the illustrated embodiment, the flow path changing portion 76 includes two first off-distribution ports 77a and second off-distribution ports 77b formed in a substantially semicircular shape capable of receiving a ball, and a rotating member 75. A third outgoing distribution port 77c formed in a groove shape crossing the
A hit distribution port 78 having a ball holding portion 78a that opens toward the peripheral surface and is bent inside to hold a ball during rotation is formed. Although the center role 13 is not shown, the ball guide gutter 41 may have the same configuration as that of the above-described embodiment in which the ball guide gutter 41 communicates with the world winning opening 36.

The ball that has fallen on the ball guiding gutter 41 is guided by the guide rib 74 and is disengaged from one of the distributing ports 77.
Alternatively, the ball that enters the hit distribution port 78, but enters the first off-distribution port 77a or the second off-distribution port 77b, loses the off-distribution port 77a when the rotating member 75 rotates by about 1/4 or more. , B
And rolls on the bottom plate 43 and further flows out to the surface of the game board 9. Since this ball does not roll in the center of the bottom plate 43, the ball has a low probability of winning in the middle symbol starting port 14c located immediately below the center, and eventually becomes a missed ball. Further, the ball that has flowed into the third off-distribution port 77c crosses the rotating member 75 and flows out onto the bottom plate 43, so that this ball cannot roll on the center of the bottom plate 43, so that the ball enters the middle symbol starting port 14c. The probability of doing so is low and the ball is out.

On the other hand, the ball that has flowed into the hit distribution port 78 remains held by the ball holding portion 78a until the opening end 78b faces directly below even when the rotating member 75 rotates. Then, when the opening end 78b faces directly below, there is a high probability that the ball will flow out of the ball holding portion 78a and enter the middle symbol starting port 14c located immediately below.

Therefore, according to the center role 13 having the ball guiding means 24 as described above, even if a hit ball enters the world winning opening 36, it does not necessarily enter the symbol starting opening 14. The profit balance between the player and the game store can be achieved while giving the player a sense of expectation and maintaining the game characteristics. In addition, the rotation speed of the rotating member 75 and the
By setting the shape and the number, it is possible to adjust the winning rate of the middle symbol starting port 14c disposed immediately below, and it becomes easy to adjust the nail in the middle symbol starting port 14c.

FIG. 8 shows another embodiment of the ball guiding means 24 provided on the center part 13. In this embodiment, a loose V-shaped movable member 79 is vertically protruded from the bottom plate 43 of the center part 13. The ball falling from the ball guiding gutter 41 can be guided to the middle symbol starting port 14c located immediately below. That is, when the movable member 79 descends and there is no obstacle on the bottom plate 43, the ball falling from the ball guiding gutter 41 flows out onto the game board 9 while maintaining the flow path at that time.

On the other hand, the sphere flowing down from the ball guiding gutter 41 when the movable member 79 is rising is temporarily stopped by the movable member 79, and when the movable member 79 descends, V
It is released from the top of the character. Therefore, the probability of flowing down the center of the bottom plate 43 and flowing into the middle symbol starting port 14c located immediately below is extremely high, and the winning rate of the middle symbol starting port 14c is improved.

Therefore, according to this embodiment, the natural prize entrance 3
Even if a ball hits the 5 or world winning opening 36, it does not necessarily mean that it hits the middle symbol starting opening 14c, so that the player and the game store are balanced in profit while giving the player a sense of expectation and maintaining game characteristics. Can be achieved. Further, by changing the movable timing and the shape of the movable member 79, it is possible to adjust the winning rate of the middle symbol starting port 14c disposed immediately below, and it becomes easy to adjust the nail in the middle symbol starting port 14c.

Reference numerals that are not described in the above embodiments have the same configurations as the same reference numerals in the above-described embodiments, and a description thereof will be omitted. Further, the present invention can be applied to the center role 13 having any configuration.

The prize winning device 80 is provided with a mounting opening 88 opened in the game board 9.
Then, it is fastened with a nail or the like passed through a mounting hole 81a provided in the base plate 81.

In the above-described winning device 80, the plunger 90 is normally retracted by the urging of the return spring 89, so that the slide plate 85 also retracts and the ball inflow portion 8
The upper part of 3 is open. Therefore, a hit ball flowing down the game section 11 can win the prize device 80. On the other hand, when the solenoid 84 is excited, the plunger 90 is pulled, the slide plate 85 projects forward, and the ball inflow portion 83 is closed. Therefore, a hit ball flowing down the game section 11 is obstructed by the slide plate 85 and cannot win the winning device 80. That is, the winning rate of the winning device 80 can be reduced by driving the solenoid 84. Conversely, based on the state in which the ball inflow portion 83 is closed, the winning device 8 can be reduced.
The winning rate of 0 can be increased.

According to such a prize winning device 80, when the number of payouts increases, the solenoid 84 is driven to lower the winning rate, or the drive is normally repeated at regular intervals, and when a specific condition is satisfied, The winning rate can be varied by adjusting the drive time so as to increase the winning rate. Incidentally, a latching solenoid capable of self-holding the position of the plunger 90 can be applied to such a winning device.

In such a winning device 80, the ball guiding path 23 can be formed by the arrangement of the obstacle nails to be implanted on the game board 9. In FIG. 2, if the nails H and H 'are arranged at a pitch at which the ball does not fall, the ball hit in a predetermined range can be guided to the world winning opening 36 which is the ball entrance . In this way, the hit ball firing speed is 1
Since the number of shots per minute is 100, the winning of the symbol starting port 14c can be controlled by controlling the number of operations per minute of the ball guiding means 24 (operations that are advantageous to the player).
The operation control of the ball guiding means 24 may be variably controlled when the number of payouts reaches a predetermined number or when a specific condition is satisfied in a game.

Although the present invention has been described with reference to the embodiment shown in the drawings, the present invention is not limited to the above-described embodiment, and can be appropriately implemented unless the structure described in the claims is changed. For example, spheres taxiway or provided within the character object, to Ru can be formed on the game surface plate, sphere guidance means ball storage member may be a ball stop member or the like.
