2. Description of the Related Art Conventionally, in a ball game machine such as a pachinko machine, a game board is provided with a symbol starting means, a symbol displaying means, a variable winning means (opening / closing type winning means) called an attacker, etc., and the symbol starting means is a game. When a plurality of special game symbols of the symbol display means fluctuate for a predetermined variation time on condition that the sphere is detected, the stopped symbol after the variation displays a specific symbol aspect (so-called, jackpot symbol aspect), The variable winning means repeats the opening / closing operation up to the set number of times based on the predetermined condition,
A special game state that is advantageous to the player occurs.

By the way, in this type of ball game machine, the symbol display means is provided in the substantially central portion of the game area, and the symbol starting means is provided immediately below the symbol display means. Therefore, in the game area. The game balls that have been launched will fall around by detouring to the left and right, avoiding the symbol display means, and it is difficult to win the symbol starting means, so for the game balls that enter the ball entrance, the outer circumference of the symbol display means Guide to the rolling stage (so-called stage portion) from the exit through one of a pair of left and right warp passages provided along the section, and by the rolling stage, guide to a position near the upper side of the symbol starting means. A center case is provided.

Here, the rolling stage generally has a gentle curved shape in which the center portion in the left-right direction is made lower than the left and right end portions corresponding to the exit port, and further, is inclined so that it becomes lower toward the front side. Therefore, the game ball guided from the ball exit to the rolling stage reciprocally rolls on the rolling stage a plurality of times in the left-right direction and then falls downward. Then, when the game ball falls in this way, there is a possibility of winning the symbol starting means immediately below. Therefore, when a game ball enters the entrance, the player rolls back and forth several times after being guided by the rolling stage through the warp passage, and the rolling in the left-right direction becomes slower. You can enjoy the game with excitement while expecting that you will win the symbol starting means until you fall from.

[0005]

As described above, in the ball game machine provided with the center case having the rolling stage, the rolling stage is formed in a curved shape which becomes lower toward the center portion in the left-right direction. Therefore, most of the game balls guided to the rolling stage from the exit of the warp passage,
After rolling back and forth to the left and right several times, it surely falls from the vicinity of the central part of the rolling stage, so the fall mode of any game ball is almost the same, and the game ball is guided from the rolling stage to the symbol starting means. There is a problem that the guidance status does not change.

The object of the present invention is to change the behavior of the game ball rolling on the rolling stage so as to improve the playability and interest of the ball game, and to design the game ball from the rolling stage. For example, the guide state for guiding to the starting means is changed to improve the playability by the rolling stage.

Passing guide means for guiding the game ball to the symbol starting means,
The passing guide means is provided with a passing state switching means for switching between a first state in which the game ball does not easily pass and a second state in which the game ball easily passes.

While the game ball is rolling back and forth in the left-right direction on the rolling stage, the game ball entering the entrance of the passage guide means is guided by the passage guide means, and then the symbol is started from the exit portion. Guided by means. By the way, when the passage guide means is switched to the first state by the passage state switching means, it becomes difficult for the game balls to pass through the passage guide means, but when the passage guide means is switched to the second state, the game is played. The sphere can easily pass through the passage guide means.

Here, when the switching from the first state to the second state by the passing state switching means is related to the number of game balls passing through the passage guiding means, the occurrence of a big hit, etc., many players are involved. As the game ball passes through the passage guide means or a big hit is generated, the game ball becomes enthusiastic and the playability is improved.

Here, the rolling stage has a valley portion and a mountain portion which are gently formed so that the game ball can roll, and a part of the mountain portion of the rolling stage is constituted by a part of the passage guide means. You may do it. Further, the passage state switching means may be configured to alternately switch the ball passage guiding means between the first state and the second state each time a predetermined number of game balls pass through the passage guiding means. Further, the passage state switching means may be configured to switch the passage guide means from the first state to the second state on the condition that the game symbol is in a predetermined stop symbol mode. Further, the passage guide means is in the first state or the second state.
You may comprise so that the player may be informed of the state.

A small iron rod 98 is embedded in the upper end of the lock lever 95, and a magnet 100 is embedded in the upper plate 99 of the rear frame 66 to limit the movement of the lock lever 95. Next, the operation of the passage guide mechanism 60 and the passage state switching mechanism 75 thus configured will be described. In a normal state, the control member 78 attracts the magnet 88 and the first iron piece 89a, and the upper ball receiving plate 85 approaches the upper surface of the swinging member 77, as shown in FIGS. 8 to 10. .

The rocking member 77 is in a locked state in which it is engaged with the engaging groove 97 of the lock lever 95 into which the lock pin 94 is fitted, and the rocking member 77 is rotated by rocking to move the movable member 68. , 69 do not open in the open state.
In such a locked state, the movable member 6 in the closed state
When the game ball 25 enters the entrance portion 60a between 8 and 69, the entered game ball 25 rolls on the upper passage 72 and rolls on the upper surface of the upper ball receiving plate 85 of the swing member 77. At this time, the control member 78 and the swinging member 77 rotate downward by the weight of the game ball 25, respectively, and through the outlet portion 60b and the outlet passage member 71, fall to the upper side of the symbol starting means 17.

As a result, the locking oblique side 43 of the cutout portion 83 of the control member 78 rotates the lock lever 95 while pushing up the locking end 44 of the lock lever 95, so that the lock pin 94 comes out of the engaging groove 97. The rocking member 77 is unlocked. Therefore, as shown in FIGS. 11 to 13, the swinging member 77 rotates in an inclined shape with the rear end portion 18 lowered, and at this time, the abutting portion 77a of the swinging member 77 moves the movable member 68, By retracting from between 69, the movable members 68, 6
9 is in the open state, the abutting portion 77a of the swinging member 77 is locked to the locking portions 68b, 69b of the movable members 68, 69 from above, and the movable members 68, 69 are maintained in the open state. It

The movable members 68, 69 in this open state
The open angle B is markedly larger than the distance A in the closed state, so that the game ball 25 can easily enter. On the other hand, the control member 78 approaches the upper ball receiving plate 85 to the upper surface of the swinging member 77, and the magnet 88 attracts the second iron piece 89b and stops.
At this time, the lower sphere receiving plate 86 faces the opening 61a. By the way, when the game ball 25 enters the entrance portion 60a again when the movable members 68 and 69 are in the open state, the entered game ball 25 is in the open state of the movable member 6
It passes through between 8 and 69, moves to the outlet part 60b, and falls to the upper side of the symbol starting means 17 through the outlet passage member 71.

At this time, since the swinging member 77 is restrained from swinging by the upper ball receiving plate 85 of the control member 78 whose rotation is blocked by the positioning locking means 87, it cannot rotate upward. Therefore, the contact portion 77a of the swinging member 77
Even if the locking between the locking portions 68b and 69b of the movable members 68 and 69 is released for a moment, the movable members 68 and 69 do not close. Then, this game ball 25 passes through the outlet portion 60b to the back side of the mounting substrate 61, and when passing through the outlet portion 60b, it collides with the lower ball receiving plate 86 and rotates the control member 78 upward, The upper ball receiving plate 85 is separated from the swing member 77 to release the restraint of the swing member 77, and the magnet 88 attracts the first iron piece 89a to stop.

By the way, the movable member 68 in the open state,

When the game ball 25 falling along the game board 5 wins the symbol starting means 17, the normal winning means 19, etc., the payout means 35 operates and the number of game balls 25 according to the prize type is paid out to the ball receiving tray 8. To be done.

By the way, the game ball 2 shot on the game board 5
When 5 rolls on the ball guide surface 53c and enters the left warp entrance 53e, it is guided to the left valley 55b of the rolling stage 55 through the left warp passage 51a and the warp exit 51c. It In this case, since the game ball 25 is guided to the valley 55b with a falling speed, the game ball 25 rolls over the mountain 55a to the opposite valley 55c, or as a reaction to the original valley over the mountain 55a. Rolling stage 5 by rolling to the portion 55b
Roll 5 back and forth several times. In this way, when the game ball 25 passes through the mountain portion 55a, it may enter the inlet portion 60a of the pair of movable members 68 and 69 in the closed state.

As described above, by the game ball 25 entering the entrance portion 60a, the control member 78 and the swinging member 77 are respectively rotated downward, and at the same time, the movable members 68 and 69 are opened to enter the ball. The game ball 25 is moved to the outlet portion 60b, and falls to the upper side of the symbol starting means 17 through the outlet passage member 71 and the outlet hole 52a. At this time, the open state detection sensor 116 detects the open state of the movable members 68 and 69, and the notification lamp 132a is turned on by a lighting signal from the notification control means 131a to notify the player of the open state.

In this way, when the game ball 25 enters the ball entrance 53e, the player is guided to the rolling stage 55 through the warp passages 51a and 51b, and then the troughs 55b and 5b.
It is possible to expect that the ball may enter the entrance portion 60a when it rolls back and forth several times while passing through 5c and the mountain portion 55a and approaches the mountain portion 55a. Moreover,
When the game ball 25 enters the entrance portion 60a, the game can be enjoyed with excitement, with the expectation that the symbol starting means 17 will be won next time.

Further, when the movable members 68 and 69 are in the open state, the notification lamp 132a is turned on, and the open state which is advantageous to the player is generated. Therefore, the player quickly starts the game ball 25. Since the player tries to enter the ball into the opened entrance portion 60a, the game property is improved. By the way, when the movable members 68, 69 are in the open state, which is in an advantageous state, but the game ball 25 for launching is lost in the ball tray 8, the player uses the card-type ball lending machine 1 to play the game ball 25. Even if the player lends the ball to the player, the player can be motivated to continue playing the game, which contributes to an increase in the profit of the hall.

Modifications of the above embodiment will be described. 1] As shown in FIG. 15, the passage guide mechanism 60A and the passage state switching mechanism 75A may be provided in the latter half of the rolling stage 55A. 2] The passing state switching mechanisms 75 and 75A are omitted, and switching of the passing guide mechanisms 60 and 60A is switched and driven by an electric actuator such as a solenoid. For example, a stop symbol after a change of the special symbol display means 22 is a big hit. The passage guide mechanism 60,
60A may be switched to the open state, and the notification lamp 132a may be turned on in this open state.

In this way, when the passage guide mechanisms 60 and 60A are switched by the electric actuator, the open state detection sensor 116 can be eliminated. 3] As shown in FIG. 16, a passage guide mechanism 60B having a similar configuration is provided on each of the left and right ends of the rolling stage 55B.
Also, a passing state switching mechanism (not shown) may be additionally provided. However, these three passage guide mechanisms 60
The game ball 25 entering the ball B falls from the exit hole 52a through a guide passage (not shown).

Further, in place of such a mechanical passage state switching mechanism, an electric passage state switching mechanism such as a solenoid drive is adopted, and when the reach occurs after the change of the special symbol display means 22, Central passage guide mechanism 6
Only 0B is switched to the open state, but if a big hit occurs, all passage guide mechanisms 60B may be switched to the open state. As described above, when the passage guide mechanism (not shown) is switched by the electric passage state switching mechanism, the open state detection sensor 116 can be omitted.

In this case, the plurality of passage guide mechanisms 60
As the passage state switching mechanism for switching B, any one of a mechanical passage state switching mechanism and an electric passage state switching mechanism may be combined. 4] When the passage guide mechanisms 60, 60A, 60B are switched to the open state, a lamp provided on the center case 50 may be turned on instead of the notification lamp 132a, and character information (for example, on the liquid crystal display 16). , "Opened state", etc.). 5] The rolling stages 55, 55A, 55B may have a plurality of ridges 55a.

6] In the above-described embodiment and modification,
When one game ball 25 has passed in the closed state, the movable members 68, 69 are switched to the open state, and when two game balls 25 have passed in this open state, the movable members 68, 69. The passing state switching mechanism 75, 75A that is switched to the closed state is adopted, but the passing state switching mechanism in which the movable members 68 and 69 are alternately switched between the open state and the closed state each time one gaming ball 25 passes. May be Also, after switching the movable members 68, 69 to the open state, the movable members 68, 69 until three or more game balls pass.
69 may be held in the open state.

7] Only one of the pair of movable members 68, 69 can be opened and closed, and only one of the movable members can be opened. 8] The exit hole 52a at the tip of the exit passage member 71 has, for example, a groove portion that can guide the game ball 25 to the symbol starting means 17 immediately below, such that the game ball falling from the exit hole 52a is below. It is desirable to have a structure in which the symbol starting means 17 is almost won. 9] The present invention is not limited to the embodiments described above, and various modifications are added without departing from the spirit of the present invention. Furthermore, the present invention is not limited to pachinko machines, and various types of game balls 25, coins, and the like. The present invention can be applied to various ball game machines such as an arrange ball machine and a sparrow ball game machine using the prize medium of.
