Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pachinko game machine, and particularly to a pachinko game machine having, for example, a variable winning ball device.

Description of the Prior Art In general, pachinko gaming machines that use pachinko balls to play games are widely used and are popular among players as one of the convenient cash registers. As is well known, a pachinko game machine has a plurality of safe holes and a winning ball device (Yakumono; commonly known as a tulip) that are determined so that a predetermined game value such as the payout of a prize ball is given when a ball hits a prize. is arranged on the game board, and is configured so that when a player hits a pachinko ball, there is a probability that the pachinko ball will land in the safe hole or the Yakumono. Conventional pachinko machines, for the purpose of providing services to players,
When the ball entered a certain winning area, a predetermined number of yakumono were opened, or a certain yakumono was opened for a predetermined time. In this way, conventionally,
Since a predetermined number of Yakumonos are only created based on the winning balls in a specific winning area, if a player wants to play the Pachinko machine until it stops and acquire a large amount of gaming value, it is a great game. It required skill and patience to play continuously for long periods of time. For this reason, in order to obtain a large amount of gaming value from a single pachinko game machine until it is controlled to stop, it took many skilled players known as pachinko players. Therefore, there is a desire for gaming parlors to provide opportunities for many players to acquire a large amount of gaming value.

Therefore, the applicant of this application first filed the patent application No. 54-145643.
No. and Japanese Patent Application No. 145644/1984, a variable winning ball device such as a Yakumono is set in a state in which it is easy to win for a relatively long period of time based on a specific gaming state, and this is repeated several times to obtain a large amount of gaming value at once. We proposed a pachinko machine that would allow players to win. However, in the previously proposed pachinko game machine, if the variable winning ball device is set in a state where it is easy to win for a relatively long period of time, a large amount of winning balls will be generated at once, and the game will be played according to the amount of winning balls. Winning balls are generated at a speed exceeding the processing speed of a winning ball processing device that counts and processes the winning balls in order to give value, resulting in the inconvenience that the processing of winning balls cannot follow the generation of winning balls. As a result, there were drawbacks such as ball clogging.

Problems to be Solved by the Invention In order to solve the above-mentioned problems, the following pachinko gaming machine can be considered. In other words, when the variable winning ball device is set to be in a state where it is easy to win a prize based on a specific gaming state, if winning balls occur to the extent that the processing speed of the winning ball processing device is exceeded, hitting of pachinko balls is immediately prohibited. It is a pachinko game machine that changes the variable winning ball device to a state where it is difficult to win. In other words, when the variable winning ball device is in a state where it is easy to win a prize, if a predetermined condition to be interrupted is met, such as when more winning balls are generated than can be processed, hitting the ball is prohibited or the variable winning ball device is in a state where it is easy to win a prize. This is a pachinko game machine that immediately disables a certain type of pachinko game machine operation, such as changing the device to a state in which it is difficult to win a prize. However, in such pachinko machines, when the variable winning ball device is in a state where it is easy to win and the game is at its peak, the game may suddenly be interrupted, or the variable winning ball device may win. This creates a disadvantageous situation for the player, such as extremely lowering the probability of winning a prize, which creates a new technical problem of making the player nervous and spoiling the fun of the game.

Therefore, when a predetermined condition to be interrupted, such as the generation of winning balls to the extent that the processing of winning balls cannot follow, is established, the present invention provides a method for performing certain types of pachinko gaming operations without irritating the player. To provide a pachinko game machine capable of interrupting a game by disabling the operation of the pachinko game machine.

Means for Solving the Problems The present invention provides a pachinko game machine including a game board forming a winning area and a ball hitting mechanism, which comprises a first pachinko game machine that is arranged on the game board and is advantageous to the player. a variable winning ball device that can freely change its state and a second state that is disadvantageous to the player;
a specific gaming state detecting means for detecting a specific gaming state that is determined to be able to alternately and repeatedly change between the above state and the second state; when the ball device is alternately and repeatedly changed into the first state and the second state,
Interruption condition detection means for detecting that the state of the pachinko game machine has reached a predetermined condition for interruption, second state detection means for detecting that the variable winning ball device is in the second state, and the interruption. The present invention is characterized by comprising a game disabling means for disabling a certain type of pachinko game operation when there is an output from the condition detecting means and when the second state detecting means outputs.

Effects According to this invention, based on the occurrence of a specific gaming state, the variable winning ball device alternates between the first state, which is advantageous to the player who is likely to win, and the second state, which is disadvantageous to the player. changes repeatedly. Then, when the variable winning ball device is repeatedly changing between the first state and the second state based on the occurrence of the specific gaming state, the state of the pachinko gaming machine should be interrupted at a predetermined time. Based on the condition being met, a certain type of pachinko game operation is disabled, and the game is interrupted.

In other words, when interrupting the game due to the occurrence of a predetermined state that should be interrupted, the system waits until the variable winning ball device enters the second state and then disables it, which is unique to the variable winning ball device. It doesn't spoil the fun of the game.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a front view of a pachinko game machine according to an embodiment of the present invention. In the configuration, the pachinko game machine 10 has a front frame 11 mounted so as to be freely openable and closable, and a game board 1 mounted on the front frame 11 so as to be freely attachable and detachable. The game board 1 has safe holes 2a to 2, which are examples of winning areas.
c, winning areas 3a to 3c with defined conditions for changing the variable display device 20 (described later) depending on the winning balls;
Multiple Yakumono (commonly known as Chulip) 4a, 4
b, and an out ball inlet 5 are formed.

Further, in the lower part of the game board 1, a variable prize winning ball device (so-called electric Yakumono) 30, which will be explained in detail with reference to FIG. 3 described later, is arranged. Game board 1
A variable display device 20 is disposed approximately at the center of the screen.

Furthermore, a display 8 for displaying messages is provided at the upper right corner of the game board 1. This display 8 displays that when a large amount of winning balls are generated, the opening of the variable winning ball device 30 is temporarily stopped.

Further, a speaker 13 and a stop command switch 12 are provided on the front frame 11 as necessary. The speaker 13 is used to notify the player of a specific game state by voice. The stop command switch 12 is used to command the variable display of the variable display device 20 to stop by operation by the player. Although one stop command switch 12 is shown in the figure, a plurality of stop command switches 12 may be provided corresponding to each of the rotating drums included in the variable display device 20.

2A and 2B are illustrative views of the back structure of the pachinko game machine, and in particular, FIG. 2A shows the game board 1.
2B shows a mechanism plate attached to the back side of the front frame 11 so as to be openable and closable. Next, the back structure of the pachinko gaming machine 10 will be specifically explained.

Game board 1 formed in the safe holes 2a to 2c
Paths 211 and 212 for guiding the winning balls to the Yakumono 4a and 4b are formed on the back side of the ball. Detection switches 22a to 22c are provided on the back surfaces of the winning areas 3a to 3c, respectively. These detection switches 22a to 22c are located in the winning area 3a.
By detecting the winning balls in ~3c, it is used to detect the conditions under which the variable display device 20 can be variably displayed. At a position slightly above the out ball entrance 5 on the back side of the game board 1, there is a path 213,
214 is provided. This route 213, 214
are safe holes 2a to 2c, winning areas 3a to 3c,
The winning balls that have been won into either the Yakumono 4a, 4b or the variable winning ball device 30 are guided to the winning ball detection switch 23. Winning ball detection switch 23
detects the winning balls guided through the path 213 one by one. Then, the winning ball payout mechanism 26 is electrically driven by the output of the winning ball detection switch 23 to pay out a predetermined number of prize balls.

A prize ball tank 27 is fixed to the upper part of the mechanism plate 25. Prize balls are supplied to the prize ball tank 27 from a supply gutter 31. The prize balls supplied to the prize ball tank 27 are arranged in one line by the alignment path 271 and then guided to the prize ball payout mechanism 26. A release path 28 is formed below the prize ball payout mechanism 26. The release path 28 is a path that guides the prize balls paid out from the prize ball payout path 26 to the prize ball payout port 14.

The prize ball payout mechanism 26 includes a cylindrical storage case 261 that stores a predetermined number of prize balls. This cylindrical storage case 261 is attached to the mechanism plate 2 by a holding member 262.
It is held rotatably in the direction along 5. Further, a solenoid 263 is connected to the cylindrical storage case 261. This solenoid 263 is for rotating the cylindrical storage case 261. 2nd B
In the figure, the cylindrical storage case 261 is the solenoid 263.
The prize balls stored in the cylindrical storage case 261 are rotated clockwise by the attraction of the
The figure shows a state in which the prize balls are being released through the prize ball payout port 14 (see FIG. 1). Note that the prize balls stored in the alignment path 271 at this time are blocked by the blocking piece 26 formed at the upper end of the cylindrical storage case 261.
4 prevents it from falling. When the above-described prize ball payout operation is completed, the cylindrical storage case 261 is rotated counterclockwise by the solenoid 263 and stopped in a substantially vertical state. Therefore, the prize ball, which had been prevented from falling by the blocking piece 264, falls into the cylindrical storage case 261. At this time, the lower end of the cylindrical storage case 261 is connected to the blocking piece 281 formed at the upper end of the discharge path 28.
to face. Therefore, the prize balls supplied to the cylindrical storage case 261 are prevented from falling by the blocking piece 281. Therefore, the cylindrical storage case 2
61 stores a predetermined number of prize balls.

Further, a light shielding plate 265 is formed on a side piece of the cylindrical storage case 261. Further, a photoelectric sensor 266 consisting of a light projecting section and a light receiving section is disposed in a part of the movement path of the light shielding plate 265. When the cylindrical storage case 261 is rotated clockwise for the prize ball payout operation, as shown in FIG. 2B, the light shielding plate 2
65 blocks light between the light emitting part and the light receiving part of the photoelectric sensor 266. Thereby, the photoelectric sensor 266 detects that the prize ball has been paid out by the prize ball payout mechanism 26.

Furthermore, a predetermined prize number detection switch 29 is provided in the upstream direction of the path 271 (on the left side in FIG. 2B). This predetermined prize ball number detection switch 29 is
When more than a predetermined number of prize balls are stored on the path 271, the operating lever 291 is pressed by the winning balls exceeding the predetermined number.

FIG. 3 is a perspective view of the variable winning ball device 30.
This variable prize winning ball device 30 opens the opening/closing plate to the front to receive balls, which will be described later, as an example of a first state that is advantageous to the player, and an example of a second state that is disadvantageous to the player. This closes the opening/closing plate to prevent the ball from being received.

Next, a more specific configuration of the variable winning ball device 30 will be explained with reference to FIG. A through hole is formed in the center of the decorative frame 31, which becomes a winning area 32 in which a ball can be won. An opening/closing plate 33 is provided on the front side of the through hole so as to be freely openable on the front side. The opening/closing plate 33 is
Its lower side is supported by a shaft 331, and a U-shaped protrusion 332 is formed on the back surface of one side (the right side in the figure). A pin 341 is implanted in the protrusion 332, and the pin 34 is inserted into a through hole bored at the tip of the lever 34.
1 is inserted. The other end of the lever 34 is a fulcrum 34
2 is supported. An opening/closing mechanism 35 for driving the opening/closing plate 33 to open or close is provided at an upper position of the lever 34 . The opening/closing mechanism 35 includes a solenoid 351 , one end of a rod 353 is connected to a plunger 352 of the solenoid 351 , and the other end of the rod 353 is connected to a central portion of the lever 34 .

The entry prize area 32 is divided into a plurality of areas 32a, 32b, and 32c as necessary. The winning balls in the winning areas 32b and 32c are directly guided to the back side of the game board 1 and reach the winning ball detection switch 23 via a path 213. The winning area 32a is an area defined so that the opening/closing plate 33 of the variable winning ball device 30 can be repeatedly driven to open and close in accordance with the passage of balls. Decorative frames 3 on both sides sandwiching this winning area 32
1, safe holes 36a and 36b are formed.
The safe holes 36a, 36b are formed to protrude to the front side from the surface of the decorative frame 31 so that they can always receive balls falling along the game board 1.
The falling ball is guided to the back side as a winning ball. and,
Light emitting diodes 6a and 6b are provided in the decorative frame 31 portion exposed when the opening/closing plate 33 is opened. The light emitting diodes 6a and 6b close the opening/closing plate 33 after a certain period of time based on the occurrence of a winning ball in the winning area 32a while the opening/closing plate 33 is open in a specific game state. Displays that the conditions for repeated opening have been met.

In operation, the opening/closing plate 33 is connected to the solenoid 35
When the plunger 1 is energized and the plunger 352 is pulled up, it is opened to the front side as shown in the figure, which is advantageous to the player. On the other hand, when the solenoid 351 is deenergized, the plunger 352 is pushed downward, and the lever 34 is rotated downward. Therefore, the opening/closing plate 33 is opened, resulting in a disadvantageous situation for the player.

FIG. 4 is a game control circuit diagram of an embodiment of the present invention. In the configuration, the winning ball detection switch 23
The detection signal is waveform-shaped into a pulse signal by the waveform shaping circuit 40 and then applied to the plus side terminal of the addition/subtraction counter 41 . Addition/subtraction counter 41
Then, the count value is added one by one in accordance with the pulse signal from the waveform shaping circuit 40. On the other hand, the output of the photoelectric sensor 266 that detects each payout of a prize ball is waveform-shaped into a pulse signal by the waveform shaping circuit 48 and then applied to the negative side terminal of the addition/subtraction counter 41. The addition/subtraction counter 41 subtracts the counted value by 1 in response to the pulse signal from the waveform shaping circuit 48. Therefore, the addition/subtraction counter 41 counts the number of winning balls that have not yet been paid out by the prize ball payout mechanism 26.

The count output n of the addition/subtraction counter 41 is given to a comparison circuit 42. This comparison circuit 42 compares the count output n with a preset value 1. and,
If the counting output n is 1 or more, that is, if there is even one winning ball that has not been paid out, the solenoid drive circuit 43 is activated and the solenoid 2 is activated.
63 is energized. With this, the cylindrical case 2
61 is rotated, and prize balls are paid out.

Further, the count output n of the addition/subtraction counter 41 is given to a comparison circuit 44, which is an example of interruption condition detection means. The comparison circuit 44 compares the counting output n with a preset value m, and if n<m, its output becomes a low level, and if n≧m, its output becomes a high level.

The output of the comparison circuit 44 is given to the determination circuit 45. Further, the determination circuit 45 is supplied with the output of the specific game state detection circuit 46. The specific gaming state detection circuit 46 detects that a specific gaming state has been entered, that is, that the variable display device 20 has entered a predetermined display state. In addition, in this embodiment, when a specific game state is entered, the variable winning ball device 30
is opened for a relatively long time, for example 30 seconds, and then closed for 10 seconds. Then, such opening and closing are repeated alternately up to 10 times. This provides maximum value to the player. Furthermore, the determination circuit 45 is given a signal from the winning ball device drive circuit 47 indicating that the variable winning ball device 30 has been closed. The output of the determination circuit 45 is given to a winning ball device drive circuit 47. The determination circuit 45 detects a winning state when the comparison circuit 44 detects n≧m, the specific gaming state detection circuit 46 detects a specific gaming state, and the variable winning ball device 30 is changed from the open state to the closed state. The ball device drive circuit 47 is disabled. In addition, the winning ball device drive circuit 47 includes the above-mentioned specific game state detection circuit 46.
The output of is given. When a specific game state is detected, the winning ball device drive circuit 47 repeatedly deenergizes and energizes the solenoid 351, thereby repeatedly opening and closing the variable winning ball device 30. Furthermore, the output of the determination circuit 45 is given to the display 8. The display 8 performs a predetermined display in response to the output of the determination circuit 45.

FIG. 5 is a circuit diagram showing details of the determination circuit 45 and winning ball device drive circuit 47 shown in FIG. 4.
In this configuration, the output of the specific gaming state detection circuit 46 is applied to the set input of a flip-flop 48. This flip-flop 48 memorizes the fact that a specific gaming state has been entered, and its Q output is given to the first input of the AND gate 451 of the determination circuit 45, as well as to the differentiating circuit 456 and
Flip-flop 45 via OR gate 454
3 reset input. AND gate 4
The second input of 51 receives the output from the comparator circuit 44,
That is, a signal that becomes high level when n≧m is detected is provided. 3rd of AND gate 451
The output of a timer 471, which will be described later, is applied to the input via an inverter 452. Further, the output of the comparison circuit 44 is applied to a reset input of a flip-flop 453 via an inverter 455 and an OR gate 454.

The output of the flip-flop 453 is given to one input of the AND gate 472 of the winning ball device drive circuit 47. The output of the timer 471 is applied to the other input of the AND gate 472. This timer 471 starts timing or outputting when the Q output of flip-flop 48 rises, and stops timing or outputting when the output of flip-flop 48 rises. The output is, for example, a pulse signal having one cycle of a high level period of 30 seconds and a low level period of 10 seconds, as shown in FIG. The output of AND gate 472 is
The signal is applied to the solenoid 351 via a driver 473 including an amplifier or the like. Also, AND gate 4
The output of 72 is given to a counter 475 via a differentiating circuit 474. This counter 475 counts the rising pulses of the differentiating circuit 474 and supplies them to the comparing circuit 476. The comparison circuit 476 compares the count value of the counter 475 with a preset value "10", and outputs a high level signal when the count value of the counter 475 reaches 10. The output of comparator circuit 476 is provided to the reset input of flip-flop 48. The output of flip-flop 48 is provided as a reset input to counter 475.

FIGS. 6 and 7 are time charts for explaining the operation of the circuits shown in FIGS. 4 and 5. FIG. Note that FIG. 6 shows the operation when the comparison circuit 44 detects n<m, and FIG. 7 shows the operation when the comparison circuit 44 detects n≧m.

The operation of the above-described embodiment will be described below with reference to FIGS. 1 to 7.

First, the operation when a specific gaming state is not detected will be explained. In this case, flip-flop 48 has been reset and therefore the output of timer 471 has been stopped. Therefore,
The output of AND gate 472 is at a low level, and solenoid 351 is deenergized. Therefore, the variable winning ball device 30 is closed.
On the other hand, when a winning ball is generated, it is detected by the winning ball detection switch 23, and the addition/subtraction counter 41
is added. Therefore, the comparator circuit 42
is detected, and the solenoid drive circuit 43 is activated. In response, the solenoid 263 is energized, the cylindrical storage case 261 is rotated, and prize balls are paid out. The payout operation of this prize ball is controlled by the photoelectric sensor 2.
66, and the addition/subtraction counter 41 is decremented. When the prize ball payout operation for the number of winning balls is completed, the count output n of the addition/subtraction counter 41 becomes 0, so the output of the comparison circuit 42 becomes low level,
Solenoid drive circuit 43 is disabled. In response, the prize ball payout operation by the solenoid 263 is stopped.

Next, the operation when a specific gaming state is detected in response to the variable display device 20 entering a specific display state will be described. The operation in this case will be explained separately in two cases: operation when the comparison circuit 44 detects n<m, and operation when the comparison circuit 44 detects n≧m. .

First, the operation when the comparison circuit 44 detects n<m will be explained. In this case, the flip-flop 48 is set by the detection output of the specific game state detection circuit 46 as shown in FIG.
Output becomes high level. Therefore, the differentiator circuit 4
56 differential pulses cause flip-flop 45
3 is reset and its output becomes high level. In response, AND gate 472 is opened.
Furthermore, a timer 471 is started by the Q output of the flip-flop 48. This timer 471
The output is a pulse signal in which a high level period of 30 seconds and a low level period of 10 seconds are alternately repeated, as shown in FIG. As mentioned above, since the AND gate 472 is open, the timer 471
The output of driver 4 is passed through AND gate 472.
73. Accordingly, the solenoid 351 is driven, and the variable winning ball device 30 is opened and closed according to the output of the timer 471. That is,
The variable winning ball device 30 is repeatedly opened for 30 seconds and closed for 10 seconds. On the other hand, counter 47
5 counts the differential pulses of the differential circuit 474 to count how many times the variable winning ball device 30 is opened. When the counting result reaches 10, that is, when the variable winning ball device 30 is opened 10 times, the output of the comparison circuit 476 becomes high level and the flip-flop 48 is reset. Therefore, the output of flip-flop 48 becomes high level, and the output of timer 471 is stopped. Therefore, the output of AND gate 472 is continuously at a low level. Accordingly, the variable winning ball device 30 also remains closed. Furthermore, the counter 475 is reset by the output of the flip-flop 48, and its count value becomes zero.

Next, regarding the operation when the comparison circuit 44 detects n≧m (when the number of winning balls for which the prize balls have not been paid out reaches m or more) after the specific gaming state is detected. explain. In this case, the same operation as described above is performed from when the specific gaming state is detected until the comparator circuit 44 detects n≧m (see the first half of FIG. 7). Comparison circuit 44 indicates n≧
When m is detected, the output becomes high level, as shown in FIG. Therefore, AND gate 4
The second input of 51 becomes high level. At this time,
The first input of AND gate 451, ie, the Q output of flip-flop 48, is at a high level. Further, the third input of the AND gate 451 is at a low level when the output of the timer 471 is at a high level, and conversely, when the output of the timer 471 is at a low level, it is at a high level. . Now, as shown in FIG. 7, consider the case where the output of the timer 471 is at a high level at the time the output of the comparison circuit 44 rises. in this case,
The third input of AND gate 451 is at low level. Therefore, the output of AND gate 451 remains at a low level. When the 30 second high level period of timer 471 ends and the output of timer 471 is inverted to low level, AND gate 451
The third input of is inverted to high level, and the output of AND gate 451 is inverted to high level. Therefore, flip-flop 453 is set and its Q output becomes low level. Therefore, AND
Gate 472 is closed, preventing the output of timer 471 from passing through. As shown in Figure 7, AND
Since the output of the gate 472 maintains a low level state, the variable winning ball device 30 will not be opened even if the output of the timer 471 becomes a high level period for the next 30 seconds. It should be noted that if the output of the comparison circuit 44 rises during the low level period of the timer 471, the flip-flop 453 is immediately set and the AND gate 472 is closed.

As described above, even when the timing to open the variable winning ball device 30 comes, the opening of the variable winning ball device 30 is prohibited, so the winning probability becomes extremely low. Therefore, during this period, the number of times prize balls are paid out is greater than the number of times winning balls are generated, and the number of winning balls for which prize balls are unpaid can be reduced. In addition,
While the winning ball device drive circuit 47 is disabled by the determination circuit 45, the display 8 is enabled and displays one of the following messages, for example.

``Prize balls are being paid out, so please wait.'' ``Prize balls are being processed, so please wait.'' ``Prize balls are being replenished, so please wait.'' As mentioned above, when the winning probability decreases, the count output n of the addition/subtraction counter 41 increases. Since n becomes smaller, eventually n<m, and the output of the comparator circuit 44 falls again. Therefore, the output of AND gate 451 becomes low level, and the output of OR gate 454 becomes high level. Accordingly, flip-flop 4
53 is reset and its output becomes high level. Therefore, the AND gate 472 is opened again, and the output signal of the timer 471 is output to the driver 47.
given to 3. As a result, the opening/closing operation of the variable winning ball device 30 is restarted.

In the above-described embodiment, an electric type is used as the prize ball payout mechanism 26, but a mechanically driven prize ball payout mechanism may be used instead.
In this case, a winning ball processing mechanism for driving the prize ball payout mechanism is provided in place of the winning ball detection switch 23. This winning ball processing mechanism uses the weight of the winning balls falling from the path 213 or 214 to drive the winning ball processing mechanism. When such a winning ball processing mechanism is provided, the variable winning ball device 3
When 0 is opened and a large amount of prize balls are generated in a short period of time, the winning balls overflow from the path 213. Therefore,
A detection switch may be provided to detect that a predetermined number or more of winning balls have accumulated in the path 213, and the output of this detection switch may be provided to the determination circuit 45 (instead of the output of the comparison circuit 44). In addition, with such a configuration, although it is possible to prevent balls from overflowing and balls from clogging, it is not possible to detect a shortage of prize balls. Therefore, the predetermined number of prize balls detection switch 29 as described above may be provided and its output may also be provided to the determination circuit 45.

Further, in the above embodiment, the winning ball device drive circuit 47 is disabled by the output of the determination circuit 45, but instead of this, the ball hitting mechanism 24 may be disabled. In this case, for example, the power supplied to the motor 241 may be cut off. Further, the shot balls may be collected without disabling the ball hitting mechanism 24, and furthermore, the supply of balls to the ball firing section may be prohibited. Incidentally, when a conventionally known manual ball hitting mechanism is used instead of the electric ball hitting mechanism 24, the ball hitting hammer may be locked.

Furthermore, in the above-described embodiment, the determination circuit 45
Although the winning ball device drive circuit 47 is disabled only during the period in which the output of the comparison circuit 44 is at a high level (that is, n≧m), once the output of the comparison circuit 44 rises, the output of the comparison circuit 44 rises. The winning ball device drive circuit 47 may be disabled until the number of balls decreases (until n=0 is detected). In this case, for example, a flip-flop is provided which is set by the rise of the output of the comparison circuit 44 and reset by the rise of the output of the comparison circuit 42, and the Q output of this flip-flop is determined by the determination circuit 4.
All you have to do is give it to 5.

FIG. 8 is a perspective view showing another example of the variable winning ball device. In this variable winning ball device 80, opening/closing wings 81a and 81b are opened and closed in the left-right direction along the game board by a solenoid 82. In Figure 8,
The state in which the solenoid 82 is energized and the opening/closing blades 81a and 81b are opened is shown. In this state, the pachinko balls received by the opening/closing wings 81a and 81b are guided into the variable winning ball device 80 and become winning balls. On the other hand, solenoid 82
When is deenergized, the opening/closing wings 81a and 81b are closed by the tensile force of the spring 83, thereby preventing the winning ball from entering the variable winning ball device 80.

Effects of the Invention As described above, according to the present invention, when the game is interrupted based on the state of the pachinko game machine reaching a predetermined condition for interruption, the variable winning ball device enters the second state.
