[Prior Art] In general, pachinko gaming machines (hereinafter abbreviated as "pachinko machines") that play games using pachinko balls have become widespread and are popular among players as one of the convenient cash registers. As is well known, a pachinko machine has a plurality of safe holes and a winning ball device (yakumono, commonly known as ``tulip'') on its game board, and when a player drives a pachinko ball along the board,
When a pachinko ball lands in a safe hole or a yakumono with a certain probability, a certain number of prize balls are paid out. In conventional pachinko machines, for the purpose of providing services to players, when a ball is hit into a certain safe hole or winning area, a predetermined number of Yakumonos are opened, or a certain Yakumono is opened for a predetermined period of time. Was. For this reason, in the past, even if prize balls were awarded depending on the pachinko playing state, a predetermined number of prize balls were only opened based on winnings in a specific winning area, so players could If you want to win a large amount of prize balls by playing the game until it stops, you need excellent gaming skills and the patience to play continuously for a long time. For this reason, many experienced pachinko players, known as pachinko players, were able to win a large amount of prize balls on a single pachinko machine until it was controlled to stop.

[Problems to be Solved by the Invention] However, in order to improve services for general players, gaming halls have to provide services not only to specific players but also to many players, although the probability of appearance is relatively low. There is also a desire to provide an opportunity to win a large amount of prize balls. If such a specific gaming state is reached, if a display is provided that allows the player to know the progress of the specific gaming state, it would be possible to make the pachinko gaming machine better for players. .

[Summary of the Invention] The present invention is a pachinko game machine equipped with a variable winning ball device, in which, when a predetermined special game state is entered, the variable winning ball device is repeatedly opened and closed until a predetermined value has been imparted. To provide a player with information regarding the number of times a variable winning ball device can be opened and closed when the variable winning ball device can be repeatedly controlled to open and close, and the number of times the variable winning ball device can be repeatedly opened and closed is limited. This is a pachinko machine that allows you to play.

[Means for Solving the Problems] The present invention is characterized by a pachinko game machine in which the variable winning ball device is repeatedly opened and closed when a specific gaming state is entered, and in which the variable winning ball device is repeatedly opened and closed. It includes a counting means for counting the number of times of control and a numerical information display means for displaying the counted value of the counting means.

[Operation] In a specific game state, the variable winning ball device can change to a first state that is advantageous to the player. When the variable winning ball device changes to the first state in the specific gaming state, a number related to the number of changes is counted by the counting means, and the counted value is made recognizable to the player by the numerical information display means. will be displayed.

3A and 3B show the variable winning ball device 3
In particular, FIG. 3A shows a perspective view thereof, and FIG. 3B shows a vertical cross section of a specific area 32a that is defined so that the variable winning ball device 30 can be repeatedly opened and closed by the passage of pachinko balls. Show the front view.

The variable winning ball device 30 has a first state that is advantageous for the player (in this embodiment, a state where the opening/closing plate described later is opened forward and pachinko balls can be received very easily) and a state that is advantageous for the player. (In this embodiment, the opening/closing plate is closed and pachinko balls cannot be received). In addition,
The first state and the second state are not limited to those of this embodiment. for example,
The second state may be a state in which it is difficult to win a pachinko ball, rather than a state in which it is impossible to win a pachinko ball, such as in a game like a so-called chulip.

Next, with reference to FIG. 3A, variable winning ball device 3
A more specific configuration of 0 will be explained. In the center of the decorative frame 31, there is a winning area 32 where a ball can be won.
A through hole is formed. An opening/closing plate 33 is provided on the front side of the through hole so as to be openable to the front side. The lower side of the opening/closing plate 33 is supported by a shaft 332, and a U is provided on the back surface of one side (the right side in the figure).
A letter-shaped protrusion 331 is formed. A through hole is bored in the protrusion 331, and a pin 341 fixed to the tip of the lever 34 is inserted into the through hole. The other end of the lever 34 is a fulcrum 342
An opening/closing mechanism 35 for driving the opening/closing plate 33 to open and 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 35.

The winning area 32 may include multiple areas 32 as necessary.
It is divided into a, 32b, and 32c. Of the winning areas 32 divided into multiple areas, area 32
The pachinko balls that have won in the balls b and 32c are guided directly to the back side and guided to the winning ball processing device 23 via a path 213. On the other hand, when a pachinko ball wins in the central area 32a among the plurality of winning areas, 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 the ball. That is, this winning area 32a is determined as a specific area.

Safe holes 36a and 36b are formed in the decorative frame 31 on both sides of the winning area 32. The safe holes 36a and 36b are formed so as to protrude forward from the surface of the decorative frame 31 so that they can always receive pachinko balls that fall along the game board 1, and the safe holes 36a and 36b are formed so as to protrude forward from the surface of the decorative frame 31, so that the pachinko balls that have fallen can be received as winning balls. It is designed to lead to the back side.

A light emitting diode 6 is arranged in the center of the decorative frame 31 to notify that the opening/closing plate 33 is in an open state.

Next, the operation of the variable winning ball device 30 will be briefly explained. The opening/closing plate 33 is opened as shown in FIG. 3A when the solenoid 51 is energized and the plunger 352 is pulled up. And solenoid 35
1 is deenergized, the plunger 352 is pushed downward, so the lever 34 rotates downward and the opening/closing plate 33 is closed.

Next, details of the specific area 32a will be explained with reference to FIG. 3B. As described above, the specific area 33a accepts pachinko balls when the opening/closing plate 33 is opened to the front side, and opens the opening/closing plate 33 again if a ball wins while the opening/closing plate 33 is open. This is the prize winning area defined by. Therefore,
It is necessary to detect the pachinko balls that have entered this specific area 32a by some kind of detection means. Generally known means for detecting pachinko balls include a micro switch, a capacitive detector that detects the capacitance that changes as the ball passes, and an inductive detector that detects the inductance that changes as the ball passes. A detector, a photoelectric sensor, etc. can be used.

In this embodiment, in order to satisfy the desire to use the game board 1 as effectively as possible, the variable winning ball device 30 is arranged as far below the game board 1 as possible. For this reason, if each detection switch as described above is normally installed in relation to the path through which pachinko balls pass, the installation space becomes large, and it is difficult to install the variable winning ball device 30 in the lower position as described above. Therefore, a detection switch with a specially devised structure is used.

That is, a path 37 that is inclined diagonally downward is formed below the back surface of the specific region 32a.
A portion on the back side (right side in the figure) of this path 37 is formed with a cutout. A ball detection member 38 is rotatably mounted in the notched portion of this path 37. The ball detection member 38 has a shape that is a combination of two "F" shaped pieces 381 and 382, and the joined portion is supported by a shaft 383.
In the ball detection member 38, one side of the F-shaped member 381 is inserted into the path 37, as shown by the solid line in the drawing. In this state, when the ball hits the specific area 32a and passes through the path 37,
During the passage, the F-shaped member 381 is pressed counterclockwise. This state is shown by a dashed line. A photocoupler 39 is provided at an upper position of the F-shaped piece 382 when the ball detection member 38 is pushed the most by the passage of the ball. The photo coupler 39 includes a light emitting part and a light receiving part, and the amount of light received by the light receiving part differs depending on whether the F-shaped piece 382 is closest or not, and detects a passing ball based on the change in the amount of received light. It is.

The ball detection member 38 is made of resin, and the F-shaped piece 382 facing the photocoupler 39 is plated with a glossy aluminum plate, stainless steel plate, or iron plate to improve the reflection of light from the light emitting part. A reflective plate 384 such as a treated plate is attached. Another method for detecting a passing ball is to use a reed switch instead of the photo coupler 39.
In addition, a permanent magnet may be used instead of the reflecting plate 384.

The rotating drum drive circuit 611 includes solenoids 57a~
Stop levers 59a to 59c by controlling biasing of 57c.
The corresponding ratchet gears 52a to 52c are disengaged from each other, and the motor 56 is rotated. Therefore, the drums 51a to 51c in each row are rotated and their display is variably displayed.

At the same time, the set output (high level signal) of the flip-flop 621 is output to the AND gate 622.
is given as one input. and gate 62
A clock pulse from a clock oscillator 623 is constantly applied to the other input of the clock oscillator 623. Therefore, AND gate 622 provides a clock pulse to ring counter 624 in response to the set output of flip-flop 621. The ring counter 624 is a numerical value from 0 to 1 that can be displayed on the one-digit segment display 502.
9 is counted cyclically, and the counted value is provided to the decoder 625 and also to the determination circuit 635. Decoder 625 performs decoding based on the count value of ring counter 624, and sequentially changes the number displayed on segment display 502 based on the count value at a period corresponding to the frequency of the clock pulse.

In this way, in a state where the rotating drums 51a to 51c are rotationally driven and the segment display 502 is variably displayed, the player can determine which combination of display states of the rotating drums 51a to 51c in each row gives the maximum value. The stop command switches 18a to 18c are appropriately pressed in the hope that the display state will be displayed. For example, when the stop command switch 18a is pressed, the rotating drum drive circuit 611 deenergizes the solenoid 57a to control the rotating drum 51a corresponding to the stop command switch 18a to stop. Similarly, the stop command switch 18b (or 18c)
When is pressed, the rotating drum drive circuit 611 deenergizes the solenoid 57b (or 57c) and controls the corresponding rotating drum 51b (or 51c) to stop. Then, all stop command switches 1
The rotating drum 51a responds to the pressure of 8a to 18c.
After instructing the drums 51c to stop, the rotary drum drive circuit 611 stops the rotation of the motor 56 and derives a high level signal indicating that all drums have stopped. This high level signal is given to the display state determining circuit 633 as a determination command signal for determining the combination state of the identification information displayed on each row of drums, and also resets the flip-flop 621. Accordingly, AND gate 622 stops deriving clock pulses from now on, so that the count value of ring counter 624 is not incremented;
A numerical value corresponding to the counted value of 4 is continuously displayed on the segment display 502.

The display state determination circuit 633 determines the combination of identification information displayed on the drums in each row based on the outputs provided from the sensors 631 and 632 in response to the determination command signal. That is, the sensors 631 and 632 are, for example, photoelectric sensors having a light emitting part and a light receiving part, and each row of the drums 51a
~51c are provided facing each other on both axially outer sides. A concentric first circumference and a second circumference are defined on each side surface of the drums 51a to 51c in each row, and on the first circumference and the second circumference, , through holes are selectively drilled at positions corresponding to the identification information displayed on each drum. Therefore, four types of identification are possible depending on the combination of whether or not a through hole is formed. For example, if the display part with holes drilled on the first and second circumferences is set to logic "1", and the part without the holes drilled is set to logic "0", then four types of 2-bit code “00”, “01”,
With "10" and "11", the combination of drum identification information displayed in the window of the decorative frame 501 can be detected. This display state determination circuit 633 is connected to the sensor 63
Based on the output of 1,632 drums 51a to 5
A score is determined based on the combination of identification information displayed in 1c, and the score value is given to the opening drive circuit 70 and the determination circuit 635 for a certain period of time. If the combination of identification information displayed on the rotating drums 51a to 51c in each row is not a combination determined to give the maximum value (for example, an all-yacht figure), then the display state determination circuit 633 Based on the combination of , one of the determination signals j2 to j4 indicating that a value smaller than the maximum value should be assigned is derived. Each determination circuit j2-j4 is applied to a corresponding timer 71-73. Each timer 7
1, 72, and 73 are the corresponding determination signals j
High level signals are derived for predetermined fixed times t2, t3, and t4 according to the inputs of signals 2, j3, and j4. The fixed times set by each of the timers 71 to 73 are selected such that t2 < t3 < t4, and for example, t2 = 10 seconds, t3 = 6 seconds, and t4 = 4 seconds.

Now, for example, if the display state determination circuit 633 derives the determination signal j2, the timer 71 derives a high level signal for a certain period of time (t2), and this signal is given to the driver 75 via the OR gate 74. In response, driver 75 continuously energizes solenoid 351 (or 451) for a fixed period of time. As a result, the opening/closing plate 33 (or 43a to 43c) of the variable winning ball device 30 (or 40) is opened for a certain period of time (t2), allowing the ball to win. At this time, when the hit balls land in the winning areas 32b and 32c, a predetermined number of prize balls are paid out according to the winning balls. However, even if the hit ball lands in the specific area 32a at this time, the extension control of the repeated opening/closing drive is not performed, and a predetermined number of prize balls are simply paid out for each winning ball.

Next, a case will be described in which the combination of identification information displayed on the rotating drums 51a to 51c in each row is determined to give the maximum value. In this case, the display state determination circuit 633 uses the determination signal j1
is derived and the OR gate 702 and determination circuit 63
Give to 5. The determination circuit 635 determines the display state of the rotary drums based on the determination signal j1 and information representing the combination of the rotary drums in each column, which is the condition for giving the maximum value preset in the combination setting section 634. Determine whether the state provides the maximum value. Subsequently, the determination circuit 635 determines whether the count value of the ring counter 624 is in a display state (for example, a state in which the number 7 is displayed) that gives the maximum value set in the combination setting section 634. , even if the combination of display states of each of the rotating drums 51a to 51c is the state that provides the maximum value,
If the display state of the segment display 502 is not displaying "7", the maximum value imparting command signal (ie, high level signal) is not derived. In this case, the determination signal j1 is applied to the timer 701 via the OR gate 702. The fixed time (t1) set by this timer 701 is a much larger value (for example, 30 seconds) than the fixed times t2, t3, and t4 based on the judgment signals j2 to j4 of the combination status of the other rotating drums. selected. Therefore,
When only the combination of display states of the rotating drums 51a to 51c reaches a predetermined state that can give the maximum value, the timer 701 drives the driver 75 for a relatively long fixed time (t1) to energize the solenoid 351. . For this reason, the variable winning ball device 30 is opened for a certain period of time (t1), and during that period, the probability of occurrence of winning balls is increased. However, in this case, since the determination circuit 635 does not derive a high level signal and therefore the AND gate 636 does not derive a high level signal, the flip-flop 703 remains reset, and the variable winning ball device 30 is repeatedly operated. No opening drive is performed.

However, the combination of the display states of the rotating drums 51a to 51c becomes a predetermined state in which the maximum value can be given, and the display state of the segment display 502 is in a state where the numerical value "7" is displayed, which allows the maximum value to be given. Then, the determination circuit 635 derives a high level signal indicating that the maximum value awarding condition has been met, that is, a specific gaming state. This high level signal is given as one input of the AND gate 636, and the flip-flop 65
Set to 1. The mismatch output (low level signal) of the comparator circuit 642 is inverted to a high level signal and provided to the AND gate 636 . Therefore, AND gate 636 derives a high level signal to set flip-flop 703. The set output of flip-flop 703 is provided to AND gate 704 as the maximum value enable signal. In this case, while the variable winning ball device 30 is being opened, it is repeatedly opened and closed for a certain period of time (t1) every time a ball hits the specific area 32a.
That is, the timer 701 inverts its output to a low level signal when a certain period of time (t1=30 seconds) has elapsed since the determination signal j1 was applied. In response, the driver 75 deenergizes the solenoid 351 to close the variable winning ball device 30. This low level signal of timer 701 is inverted by inverter 705 and applied to delay circuits 706 and 707. The delay circuit 706 is set to a delay time corresponding to the opening time when the variable winning ball device 30 is driven to open and close in the state where the maximum value can be given. Delay circuit 7
07 is set to a delay time slightly longer than the delay time of the delay circuit 706. A high level signal delayed by a certain period of time from the delay circuit 706 is sent to the AND gate 70.
It is given as one input of 4.

In addition, in this embodiment, the fixed period when the variable winning ball device 30 is opened once is a fixed time (t1), but the fixed period is, for example, when a fixed number of balls (for example, 10) win in the winning area 32. It is also possible to set the period until Alternatively, the fixed period may be a period until a fixed time elapses or until a fixed number of balls are won, whichever comes first. In this case, a ball counter that derives an output when a certain number is detected in relation to the winning area 32 is provided, and its output is replaced with the output of the timer 701, or the timer 701
The output of the ball counter and the output of the ball counter may be derived through an OR gate.

By the way, during the operation of the variable winning ball device 30, when a ball is hit into the special prize area 32a, the photocoupler 39 outputs an output to set the flip-flop 708. Therefore, AND gate 704 derives a high level signal and provides a differential command signal to timer 701 via OR gate 702. In response, the timer 701 again derives a high level signal for a certain period of time (t1). In this way, the state where maximum value can be added (specific gaming state)
In this case, when a hit ball enters the special prize area 32a of the variable winning ball device 30, once the ball hits the special prize area 32a of the variable winning ball device 3
0 is closed, the variable winning ball device 30 is opened again for a certain period of time (t1), and the special prize area 3
The operation is repeated every time a winning ball lands on 2a. Therefore, the player can advantageously win a large amount of prize balls.

Next, the operation of the notification circuit 65, which is a feature of this embodiment, will be explained. The maximum value addition detection output from the determination circuit 635 is differentiated by a differentiation circuit 651 and provided as a set input to a flip-flop 652. By setting the flip-flop 652, the high level signal is maintained, the jackpot indicator 19 is lit, and the sound effect generating circuit 6 is turned on.
53 is driven, and a sound effect representing a specific gaming state is output from the speaker 17. That is, by lighting the jackpot display 19 and sound effects output from the speaker 17, it is announced that the gaming state has become a specific gaming state in which the maximum value can be given. This notification excites the player and increases his/her interest in the game.

The notification circuit 65 stops the notification based on the output of the predetermined value provision state detection means 64.
That is, when the predetermined value has been awarded after entering the specific gaming state, it is detected by the predetermined value award state detection means 64, and its output is given as a reset input to the flip-flop 652. In response, the flip-flop 652 is reset, the jackpot indicator 19 is turned off, the drive of the sound effect generation circuit 653 is stopped, and the output of the sound effect from the speaker 17 is also stopped.

Furthermore, in this embodiment, the variable winning ball device 30
When the game is opened and the game becomes easy to win, the light emitting diode 6 is turned on to notify the player of the game. This operation will be explained mainly with reference to FIG. AND gate 761 causes transistor 762 to conduct during the set output of flip-flop 703 and the output of timer 701. In response, the light emitting diode 6 emits light to inform the player that the player is in a specific game state and is in a state where it is easy to win a prize in the variable winning ball device 30. Therefore, the player sees the display and selects the special prize area 32a of the variable winning ball device 30.
It is possible to concentrate on playing the ball hitting game so that the ball hit into the hole wins the prize.

By the way, when the ball hits the special prize area 32a, the photocoupler 39 detects this and sets the flip-flop 708. The set output of flip-flop 708 is differentiated by differentiation circuit 709 and applied to counter 641. The counter 641 is variable winning ball device 3 in a specific game state.
Count the number of openings and closings of 0. The count value of the counter 641 is given to the decoder driver 644 and displayed on the segment display 7.

Further, the count value of the counter 641 is
given to 2. The comparison circuit 642 includes a setting device 6.
43 preset limit number of times (for example, 15
times) are entered. Therefore, comparison circuit 6
42 compares the counted value of the counter 641 with the limit number of times during the period when the set output of the flip-flop 703 is given as a comparison command signal. When the comparison circuit 642 detects that the count value has reached the limit number of times, it derives a coincidence output and resets the flip-flop 703 and the counter 641. Therefore, even if a hit ball enters the special prize area 32a from now on, since the AND gate 704 is disabled in response to the reset of the flip-flop 703, it is prohibited to repeatedly open the variable winning ball device 30. be done.
That is, the variable winning ball device 30 is repeatedly opened a limited number of times as long as there are winning balls in the special prize area after entering the specific game state. Note that the output of the comparison circuit 642 may be used to issue a stop command.

As described above, according to this embodiment, the player can win a large amount of prize balls without much effort in the specific gaming state, so that the player can work hard to play the game in order to reach the specific gaming state, which increases the interest of the game. It has the advantage of increasing the

In addition, in a specific game state, the player is visually and audibly notified of the state by the notification circuit 65, so the player can quickly learn about the state and use it to plan the game. It has advantages that help you to stand up.

Furthermore, in a specific gaming state, when the variable winning ball device is in a state where it is easy to win, that is, when the variable winning ball device is in the open state, this is displayed on the light emitting diode 6, so that the player can play the game. It also has the advantage of being even more useful in formulating the above strategies.

In addition, in one specific game state, the number of repetitions of the opening/closing control of the variable winning ball device is limited, but the number of repetitions is clearly displayed on the segment display 7, so that It is possible to provide a device that makes it easy to grasp the progress of the game. In addition, by displaying the number of times the variable winning ball device has been opened and closed or the remaining number of times that can be repeated, the pachinko game machine can effectively provide players with powerful game information.

In the above embodiment, the rotating drums 51a to 51c
Although the specific gaming state is determined by the display combination of the segment display 502 and the segment display 502, the specific gaming state is determined by the display combination of only the rotating drums 51a to 51c. Good too. In this case, the determination circuit 635 may output a determination output only based on the display states of the rotating drums 51a to 51c, and the display drive control circuit 62 may be omitted.

In addition, the display means for determining the specific game state may not be of a mechanical construction like the rotating drums 51a to 51c, but may be constructed of display segments or the like whose display can be changed electrically. .

FIG. 8 is a circuit diagram showing another example of the drive control means. The difference between the embodiment shown in FIG. 8 and that shown in FIG. 7 is as follows.
After entering one specific game state, the number of opening and closing of the variable winning ball device 30 is changed according to the number of winning balls in the special prize area 32a, and when the number of opening and closing exceeds the limit number of times, opening and closing more than the limit number of times is prohibited. This is the point that is being made.

Specifically, the predetermined value provision state detection means 64'
A driving circuit 700' that repeatedly opens and closes for a certain period of time is constructed and operates as described below. That is, when AND gate 636 derives a high level signal, the maximum value enable signal, flip-flop 703 is set;
Gate circuit 645 is opened. Accordingly, setter 6
The limit number of times set in 43 is the gate circuit 64.
5 to the subtraction circuit 646. Therefore, the subtraction circuit 646 sets a limit number of times, and the counted value (initially, the limit number of times) is given to the decoder 646 and the zero detection circuit 647. At this time, the decoder 644 displays the limited number of times on the segment display 7 as the remaining number of times. Further, the determination signal j1 is derived at the time of generation of the maximum value activation signal. In response to this judgment signal j1, the timer 70
1 is activated to open the variable winning ball device 30.
In this state, when a hit ball lands in the special prize area 32a, the photo coupler 39 detects the winning ball. At this time, the zero detection circuit 647
It is detected that the count value of 6 is not zero and its output is set as a low level signal. This low level signal is inverted by an inverter 648 and an AND gate 711
is given as one input. Therefore, the AND gate 711 derives a high level signal every time there is an output from the photocoupler 39, sets the flip-flop 708, and also sets the flip-flop 708.
A subtraction command is given to the circuit 649, and an addition command is given to the addition/subtraction circuit 649. The subtraction circuit 646 counts the calculated remaining number of times each time there is an output from the AND gate 711. The addition/subtraction circuit 649 counts the number of times that the switch can actually be opened and closed.

Then, when the first opening is completed, the delay circuit 706 derives a high level signal. In response, AND gate 704 derives a high level signal and provides an operating command to timer 701 via OR gate 702 . Therefore, the timer 701 operates to open the variable winning ball device 30 again for a certain period of time (t1). At this time, the output of the AND gate 704 is given to the addition/subtraction circuit 649 as a subtraction command input. In this way, the subtraction circuit 646 and the addition/subtraction circuit 6
49 is provided, even if a large number of balls hit into the special prize area 32a during one opening period, the subtraction circuit 646 counts the remaining number of calculations, and the addition/subtraction circuit 646 This is to count the number of times the variable winning ball device can actually be opened.

The above operation is repeated until the count value of subtraction circuit 646 becomes zero. When the count value of the subtraction circuit 646 becomes zero, the zero detection circuit 647 detects this and makes its output a high level signal. Therefore, AND gate 711 is disabled and does not give a high level signal to addition/subtraction circuit 649 and subtraction circuit 646 even if there is an output from photocoupler 39. However, since the flip-flop maintains the set state, the opening and closing operations of the variable winning ball device 30 are repeated until the count value of the addition/subtraction circuit 649 becomes zero.

When the variable winning ball device 30 is opened and closed a limited number of times, the count value of the addition/subtraction circuit 649 becomes zero. Accordingly, the zero detection circuit 64a detects it, derives a high level signal, and supplies it to the monostable multi-channel circuit 64b.
In response, the monostable multi 64b derives a high level signal for a certain period of time and supplies it to the AND gate 64c. The AND gate 64c first detects the zero detection circuit 64.
Since a high level signal is given from 7, the output of the monostable multi 64b is derived and the flip-flop 703 is reset. As a result, the AND gate 704 is subsequently disabled and the variable winning ball device 30 is prohibited from being opened repeatedly.

In this way, if a relatively large number of balls enter the special prize area when the variable winning ball device 30 starts to be opened, even if no winning balls appear in the special prize area during opening and closing of a certain round, the limit number of times can be increased. It is ensured that only the variable prize winning ball device is opened.

As another example of displaying information related to the number of openings, instead of displaying the remaining number of openings counted by the subtraction circuit 646 of this embodiment, the number of openings may be displayed as shown in FIG. good. Furthermore, the remaining number of times may be displayed in the embodiment shown in FIG. 7 as well.

In addition, as another modification, the AND gate 63
6 and for a relatively long time (e.g. t
1 and the delay time of the delay circuit 706 multiplied by the limit number of times).
An OR gate 64e may be provided to derive either the output of the timer 64d or the output of the AND gate 64c, and the flip-flop 703 may be reset by the output of the OR gate 64e.

In addition, the special prize area 32 is a part of the winning area of the variable winning ball device 30 of this embodiment, but the game board 1
It can be placed anywhere on the top.

[Effects of the Invention] As described above, according to the present invention, when a predetermined special gaming state is reached, the variable winning ball device can be repeatedly controlled to open and close until a predetermined value has been awarded, and the player It is possible to provide a pachinko game machine that can improve the service provided to players. Further, it is possible to provide a pachinko game machine that can notify a player of information regarding the number of times the variable winning ball device is opened and closed when the number of times the variable winning ball device can be repeatedly controlled to open and close is limited. can.
