Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a pachinko game machine, and particularly to a pachinko game machine with improved drive control of a variable winning ball device.

U. Prior Art] In general, pachinko gaming machines that use pachinko balls to play games have become widespread and are popular among players as a convenient form of leisure. As is well known, a pachinko game machine has multiple safe holes and winning ball devices on its game board.
When a player hits a pachinko ball, a certain number of prizes will be paid out if the player hits a safe hole or a yakumono with a probability of a pachinko ball forming.

By the way, conventional pachinko gaming machines, for the purpose of providing services to players, open a predetermined number of yakumono when a ball hits a specific safe hole or winning area, or open a yakumono for a predetermined period of time. Was. For this reason, conventionally, prizes are awarded depending on the gaming state, but only a predetermined number of prizes are awarded based on the winning balls in a specific winning area, so it is difficult for players to stop playing the pachinko machine. In order to win a large amount of prizes by playing games up to that point, it was necessary to have excellent gaming skills and the patience to play continuously for long periods of time. For this reason, it was often the skilled players known as Bachi-Pros who were able to win a large amount of prizes by controlling one Pachinko game machine to stop.

However, there is a desire for gaming halls to provide many players with the opportunity to win a large amount of prizes. Therefore, in Japanese Patent Application No. 54-145643 and No. 54-145644, the applicant of the present application previously proposed a state in which variable winning balls Iff such as Yakumono are easy to win for a relatively long time based on a specific gaming state. He proposed a pachinko machine that would allow players to win a large amount of prizes at once.

[Problems to be Solved by the Invention] However, the previously proposed system merely puts the variable winning ball device in a state where it is easy to win for a relatively long period of time, so it is difficult to place the variable winning ball device near the variable winning ball device. Depending on the adjustment state of the implanted nails, some machines produce more than 10 winning balls during one opening period of the variable winning ball device, while others rarely produce any winning balls. There were times when the probabilities varied more than expected. Therefore, there is a demand for a pachinko game machine that can limit the number of winning balls that can be won within one opening period of the variable winning ball device, especially the upper limit thereof, to a fixed number.

Further, in the previously proposed pachinko game machine, the variable winning ball device is opened for a certain period of time based on a specific game state, and is once opened and then opened again based on a condition that allows it to be opened repeatedly.

Therefore, the main purpose of the present invention is to make it easier to win with the variable winning ball device for a relatively long time based on a specific gaming state, and to repeatedly bring the variable winning ball device into a state where it is easier to win. In machines where you can win again based on conditions, we have added a limit to the number of steps that can be won during one period to reduce the variation in the number of winning balls for each pachinko machine. To provide a Pachinko game machine which can reduce the variation in the number of prize balls given when a specific game state is reached compared to the conventional machine by limiting the number of prize balls to a certain range.

[Means for solving the problem] This invention puts the variable winning ball device in a state where it is easy to win based on a specific game state, and when the number of winning balls during that period reaches a certain number allowed or A drive control means that changes the variable winning ball device to a state in which it is difficult to win when a certain period of time has elapsed without reaching the number, and drives the variable winning ball device to a state in which it is easy to win again if a repeat condition is detected at that time. It is a pachinko game machine that includes.

[Function] In response to entering the specific game state, the drive control means,
To put a variable prize winning ball device into a first state advantageous to a player for a certain period of time. In this state, if a fixed number (for example, 10) of winning balls occur in the variable winning ball device, a detection output is derived from the output of the predetermined winning ball number detection means, and according to the output, the drive control means This puts the variable winning ball device in a second state that is disadvantageous to the player. At this time, if there is no output from the predetermined number of winning balls detecting means within a certain period (for example, 30 seconds), the drive control means controls the variable winning ball device to a second position that is disadvantageous to the player according to the elapse of the certain period of time. state.

Further, the drive control means drives and controls the variable winning ball device again to the state of box 1 in accordance with the output of the repetition condition detection means.

FIG. 5 is an illustrative diagram showing details of the rotary drum display device 1150A.

Next, the configuration of the variable winning ball/variable display device 30 will be explained in detail with reference to FIGS. 3 to 5.

The variable winning ball/variable display device 30 has a configuration in which the variable winning ball device 40 and the variable display device 50 are integrally attached to a mounting plate 31. Specifically, the mounting plate 31 has an opening 32 formed therein. The opening 32 is a horizontally long rectangular hole so as to become a winning area when the opening/closing plate 41 of the variable winning ball device 40 is opened. The mounting plate 31 has display windows 33a and 33b for displaying identification information drawn on the rotating drum included in the rotating drum display mechanism 50A.
, 33c are formed. Furthermore, a frame member 34 is attached to the top of the mounting plate 31. Frame member 34
A segment display device 50B is attached to the segment display device 50B, and an inverted V-shaped ball receiving plate 341 is attached to the upper part of the segment display device 50B.

The balls received by the ball receiving plate 341 are guided to the back side through a hole that becomes the winning area 3a. Furthermore, passage areas 342 and 343 for allowing balls to pass are formed in the horizontally extending portion of the frame member 34, and in order to change the fall of the balls that have passed through the passage areas 342 and 343, Approximately in the center of the mounting plate 31 and above the opening 32, a suitable number of obstruction nails 35 are arranged horizontally in one row 4a. A guide member 36 is installed between the obstruction nail 35 and the opening 32. The guide member 36 has guide plates extending in the vertical direction at a plurality of locations in the lateral direction, and functions to guide the ball in the vertical direction and cause it to fall.

The variable prize winning ball device 4o is the first one that is advantageous for the player.
In the second state, the opening/closing plate 41 is opened forward and balls can be easily accepted, and in the second state, which is disadvantageous for the player, the opening/closing plate 41 is closed and balls cannot be accepted.

The structure of such a variable winning ball device 40 will be explained in more detail. The variable ball device 40 includes an opening/closing plate 41 rotatably mounted on the nfJ plane of the frame member 42 (that is, the portion related to the opening 32). Triangular side walls 411' and 412 protruding toward the back side are provided on both side edges of the opening/closing plate 41. The side walls 411, 412 are rotatably attached to the side surface of the frame member 42 via a shaft 413. Frame member 42
Paths 421 and 422 are formed below. The back side of the frame member 42 is covered with a cover 423. The opening 32 when the four opening/closing plates are in the open state becomes a winning area 43 where balls can easily be won. The winning area 43 is horizontally divided into a plurality of winning areas 43a to 43c. Prize winning area 4
3a is an area in which conditions are defined such that the variable winning ball device 40 can be placed in a state where it is easy to win by opening the opening/closing plate 41 again with a winning ball while the opening/closing plate 41 is open in a specific game state. A detection switch 44a is provided for that purpose. The detection switch 44a is for detecting a ball that enters the winning area 43a, is guided to the back side, and falls downward. Further, the winning balls in the winning areas 43a to 43c are guided downward via paths 421 and 422, respectively. Below the routes 421 and 422, there is a prize area [4
A detection switch 44b is provided for detecting a ball that has won a prize. This detection switch 44b constitutes a part of the counting means.

An opening/closing drive mechanism 45 is coupled to the opening/closing plate 41 . The opening/closing drive mechanism 45 includes a solenoid 451, a T-shaped lever 453, a rod 455, and a spring 456. The center of the T-shaped lever 453 is rotatably attached to the mounting plate 31 by a pin 454. One end of the short side of the T-shaped lever 453 is engaged with a plunger 452 of a solenoid 451, and a spring 456 is connected to the other end of the short side of the lever 453. Furthermore, the T-shaped lever 4
One end of a rod 455 is engaged with the long side end of 53;
The other end of the rod 455 is connected to the side wall of the opening/closing plate 41 and the bottle 413.
are connected by. When the solenoid 451 is electrically deenergized, the other end of the short side of the 1'-shaped lever 453 is pulled by the spring 456, so that the lever 45
The tip of the long side 3 is in a state of being pulled down, and a downward force is applied to the side wall of the opening/closing plate 41 by the rod 455, so that the opening/closing plate 41 is in a closed state. Conversely, when the solenoid 451 is electrically energized, the T-shaped lever 4
53 is rotated clockwise (clockwise in Fig. 4Δ), and the rod 455 is pulled upward to close the opening/closing plate 41.
is opened forward.

In this embodiment, the variable winning ball device 40 is in an open state in which the opening/closing plate 41 is easy to win a ball in the first state, which is advantageous to the player, and in the second state, which is disadvantageous to the player. The case where the opening/closing board 41 is closed and the balls cannot win a prize has been explained. However, the structure of the variable winning ball device and the state of change between the first state and the second state are not limited to those of the above-mentioned embodiments, and may take on various structures and states. For example, in other examples of variable winning ball devices, such as the so-called tulip, in the first state that is advantageous to the player, a pair of ball receiving pieces open on the left and right, making it easier for balls to win. In the second state, which is disadvantageous to the player, the ball receiving piece is open and it is difficult for the ball to win. Further, the variable display device has a structure including an opening/closing plate provided on the game board 1 so as to be openable/closable, a ball socket provided on the top of the opening/closing plate capable of receiving one ball, and a second In the first state, the opening/closing board is closed and balls can only be won at the ball entrance provided at the top of the opening/closing board, with a low probability of winning a winning ball.In the first state, the opening/closing board is open and there is a high probability of winning a winning ball. It is also possible to configure the system so that winning balls are generated.

Next, details of the variable display device 50 will be explained. Variable display device 50 includes a rotating drum display mechanism 50A and a segment display 50B.

The rotary drum display device 150A has a configuration as shown in FIG. Referring to FIG. 5, the rotating drum group 51 is

is pivotally supported on both sides of the box 54, and a gear 551 included in the rotational force transmission 8m55 is fixed to one end of the drum shaft 53. The gear 551 meshes with a gear change gear 552. A motor 56 for driving the rotating drum is mounted on the side of the box 54. Motor 56 is a geared motor, and its drive gear is engaged with gear 552. Therefore, the rotational force of the motor 56 is transmitted to the drum shaft 53 via the gears 5-52 and 551, and the rotating drum group 51 is rotationally driven.

On the rear back side of the box 54, each row of rotating drums 51a

It is supported on both sides of 4. Locking levers 58a to 58
A claw-like portion 582 is formed at each tip of C. The claw-like portions 58 of each of the locking levers 58a to 58C
2 is adapted to engage with each of the corresponding ratchet gears 528-520 to stop the rotating drums of each row and maintain the locked state.

The specific game state in which the variable winning ball device 40 can be put in the first state is determined by the combination of identification information such as the picture pattern in each row displayed on the rotating drum display mechanism 50Δ and the segment display 50B. The specific game state is determined by the combination with the display state of the numerical information displayed. Note that the specific game state may be determined only by the combination of the identification information displayed on the drums in each row of the rotating drum display mechanism 50A. .

Alternatively, without using the rotary drum display mechanism 50A, a plurality of segment displays capable of electrically displaying numbers O to 9 are arranged, and the decision is made based on the combination of display information of multiple digits displayed by the segment displays. It may be possible to do so.

FIG. 6 is a game control circuit diagram of an embodiment of the present invention. In the configuration, the game control circuit 60 includes a variable display possible condition detection circuit 61, a rotating drum drive control circuit 62, a display drive circuit 63, a specific game state detection circuit 64, a predetermined number of winning balls detection circuit 65, and a predetermined value imparting state detection circuit. 66, includes a numerical information display drive circuit 67 and a drive control circuit 70.

The variable display enable condition detection circuit 61 detects conditions that enable the variable display device 50 to perform variable display. The rotary drum drive control circuit 62 is a circuit for driving the rotary drum display mechanism 50A based on variable display enable conditions. The display drive circuit 63 is a circuit for display-driving the segment display 50B based on variable display enable conditions.

The specific game state detection circuit 64 is connected to the rotating drum display mechanism 50.
This is a circuit for detecting that a predetermined specific gaming state has been entered based on a combination of the display state of A and the display state of the segment display 50B. In addition, in this embodiment, the specific gaming state detection circuit 65 detects not only a specific gaming state but also a gaming state in which a smaller gaming value can be awarded than the specific gaming state, and the variable winning ball device 4o is Contains a function to detect conditions that can result in a state. For this reason,
In this embodiment, the type of gaming state is Φ-wealth, and the Pajinko gaming machine can be made more interesting to the Ministry of Gaming. The predetermined number of winning balls detection circuit 65 is a circuit that counts the number of winning balls in the variable winning ball device 40 in a specific gaming state and derives a detection output when the number of balls reaches a predetermined number allowed in advance. be. The predetermined value awarding state detection circuit 66 is a circuit for detecting a state in which a predetermined value is given in a specific game state (for example, a state in which a large number of prize balls set as the number of prize balls are paid out). The numerical information display drive circuit 67 is a predetermined winning ball number detection circuit 65
This is a circuit for displaying a predetermined numerical value on the numerical information display 6 based on the output.

Figure 7 shows the game shown in Figure 6! It is a circuit diagram showing an example of a detailed configuration of a drive control circuit 70 and a predetermined winning ball number detection circuit 65, which are features of this embodiment, of the II control circuit. Referring to FIG. 7, drive control circuit 70 includes an OR gate 71, timers 72 to 74, a driver 75, and a constant time repetitive opening/closing drive circuit 76. Here, driver 7
5 is for driving the variable winning ball device 40 to the first state by energizing the solenoid 451 during the output period of the OR gate 71. The constant time repeated opening/closing drive circuit 76 basically puts the variable winning ball device 4o into a state where it is easy to win continuously for a certain period of time (for example, tl=30 seconds).

Next, the specific operation of the pachinko game machine 10 of this embodiment will be explained with reference to FIGS. 1 to 7.

The player puts the ball borrowed from the ball lending machine into the ball waiting gutter 13,
After adjusting the strength of the ball by rotating the ball-hitting handle 14, the ball-hitting switch 14s is pressed. In response to pressing the ball hitting switch 14s, power is supplied to the motor 241, and the motor 2
41 is rotationally driven and the ball hitting hammer 243 is intermittently rotated, whereby balls are driven into the game board 1 one by one. When a player is playing a batting game in this way,
When a hit ball lands in any of the safe holes 2a to 2c, 4a or 4b, a prize ball release mechanism is activated to control the release of a predetermined number of prize balls for each winning ball.

Furthermore, when a hit ball lands in any of the winning areas 3a to 3G, the corresponding detection switch 22a or 22b derives a high level signal, this signal is given to the drive circuit 621 via the OR gate 611, and the timer 622
given to. Furthermore, the high level output from the OR gate 611 is applied to a Noritsu flop 631 included in the display drive circuit 63, and the flip flop 631 is connected to the cell 1. The drive circuit 621 energizes the solenoids 57a to 57c based on the signal from the OR gate 611 to release the engagement between the pawls 582 of the locking levers 58a to 58c and the corresponding ratchet gears 52a to 52c. , simultaneously drives the motor 56 to rotate. As a result, the rotating drums 51a to 51c in each row are rotationally driven, and the display state of the rotating drums is varied. Also, flip-flop 6
The set output of 31 is given as one input of AND gate 632. The output clock pulse of the clock oscillator 633 is always applied to the AND gate 632 as the other input. Therefore, the AND gate 632 derives a -C pulse in response to the set output of the flip 70 knob 631, and supplies it to the converter circuit 34. The ring counter 634 responds to the input of the clock pulse by
It cyclically counts the numerical values O to 9 that can be displayed on the segment display 50B, and the counted value is given to the decoder driver 635 and the determination circuit 645 included in the specific game state detection circuit 64. Decoder driver 635
decodes the 81 value of the ring counter 634 and sequentially changes the number displayed on the segment display 50B based on the counted value in synchronization with the cycle of the clock pulse.

In this manner, the rotary drums 51a to 51C are rotationally driven and the display 50B is variably displayed in segment 1, whereby mechanically variable display and electrically variable display are performed simultaneously.

As described above, in a state where the rotating drums 51a to 51c and the segment display 50B are variably displayed, the player can select the rotating drums 51a to 51 in each row.
The player presses the stop command switch 17 at an arbitrary timing, expecting that the combination of display states c will result in a specific gaming state. Note that the timer 62 starts after the variable display starts.
Stop command switch 17 within a certain period of time set in 2.
If is not pressed, the output of the timer 622 issues a stop command. Depending on the output from the press of the stop command switch 17 or the output from the timer 622, the drive circuit 621 deenergizes the solenoids 57a to 57c in a predetermined order (or irregular order), and accordingly deactivates the locking levers 58a to 58c.
The ratchet gears 52a to 52 corresponding to the claw-like portions 582 of
c are respectively engaged, and the rotating drums 51a to 51c are sequentially stopped. In addition, the drive circuit 621, with some finesse, stops the rotation of the motor 56 and derives a high level signal indicating that all rotating drums have stopped. This high level signal is sent to the flip-flop 63
1 is reset, and a determination command IH No. 2-6 is given to the input state determination circuit 643. Resetting flip 70 knob 631 causes -C ant gate 632 to stop deriving clock pulses. Therefore, the ring counter 634 stops incrementing the 81 value, and accordingly, the number corresponding to the t1 value counted by the ring counter 634 is continuously displayed on the segment display 50B.

The display state determination circuit 643 determines the identification f? displayed on the rotating drum of each column based on the outputs given from the sensors 641 and 642 in response to the determination command signal. J information combinations are determined. By the way, in this embodiment, the sensor 64
1 and 642 are photoelectric sensors having a light projecting section and a light receiving section. The light projecting part and the light receiving part of each sensor 641, 642 are provided facing each other on the outer side of the rotating drum in the axial direction. Further, on each side of the rotating drums 51a to 510, although the illustrations are omitted in FIG.
On a first circumference and a second circumference concentrically having different radii, a portion with a through hole and a through hole are formed at positions corresponding to the identification information displayed on the rotating drum, respectively. A portion that is not covered is formed. So-〇, each rotating drum 51a
Depending on the stop state of ~51c, four types of identification information are displayed. For example, the first and second
The parts on the circumference where through holes are drilled are set to logic "1", and the parts where no through holes are drilled are set to logic "0".
How can I create four types of 2-bit codes, roof and rol?
1, riot, and N1J can be defined, and the combination of identification information of the rotating drums in each row can be detected. and,
The display state determination circuit 643 uses the rotating drums 51a-51G.
The score is determined based on the combination of identification information displayed in the drive control circuit 70 and the determination circuit 6.
Give to 45.

If the combination of identification information displayed on the rotating drums 51a to 51C is not a combination of a specific gaming state, that is, a combination determined to give the maximum value (for example, all symbols A), the display state The determination circuit 643 derives one of the determination signals j2 to J4 indicating that a value smaller than the maximum value should be assigned based on the combination at that time. Each determination signal j2-j4 is given to a corresponding timer 72-74. Each timer 72, 73, 74 receives a corresponding judgment signal j2. Depending on the input of j3゜j4, a predetermined fixed time t2, t3.
A high level signal is derived for t4. Here, the fixed time set by the timers 72 to 74 is t
2≧t3≧t4, for example, t=10 seconds,
It is assumed that t3=6 seconds and t4-4 seconds. Note that the determination circuit 645 determines that the determination signal is other than J1 (i.e., j2 to j4
), the display state of the segment display 50b is not determined at all.

Now, for example, the display state determination circuit 643 outputs the determination signal J2.
Assuming that the timer 72 is derived for a certain period of time t
2) A high level signal is derived.

This high level signal is applied to the driver 75 via the OR gate 71. In response, driver 75 continuously turns on solenoid 451 for a predetermined period of time. Therefore, the opening/closing plate 41 of the variable winning ball device 40 is operated for a certain period of time t.
2 [The ball is opened and the ball is allowed to win. At this time, when the hit ball lands in any of the winning areas 43a to 43c, the prize ball discharging mechanism pays out a predetermined number of prize balls according to the winning ball. In this case, even if the ball hits the winning area 43a, the opening/closing operation of the variable winning ball device 40 is not controlled to extend.

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 643 derives a determination signal J1, and this signal j1 is given to the determination circuit 645, and the flip 70 knob 7
61 set input. Accordingly, flip-flop 761 is set. In addition, the determination circuit 645
determines whether or not the durability value of the ring counter 634 is in a display state (for example, a state in which 7 is displayed) in which the maximum value set in the combination setting section 644 should be given according to the judgment signal @J1. do. At this time, the determination circuit 645
The combination of the display states of the rotating drums 518 to 51C is the state that provides the maximum value, and -C is also the segment display 5
If 0B does not display the number 7, the maximum value imparting command signal j○ (high level signal) is not derived. in this case,
Flip-flop 7 set by judgment signal J1
The set output of 61 is sent to timer 7 via OR gate 762.
63. In response, the timer 763 starts a certain period of time t.
1, a high level signal is derived during that period, and the high level signal is applied to the collector of transistor 764. At this time, the mismatch output of the comparison circuit 653 (low level) is inverted to high level by an inverter 655 and is applied to the base of the transistor 764. Therefore, transistor 764 is conductive during the period when comparator circuit 653 is deriving a mismatch output, and the output of timer 763 is passed to driver 75 through OR gate 71.
give to In response, the driver 75 energizes the solenoid 451 to open the opening/closing plate 41. In this case,
Since flip-flop 766 is not set, AND gates 651 and 767 remain disabled. Therefore, the predetermined winning ball number detection circuit 65 does not detect the winning balls that have entered the winning area 438, and the variable winning ball device 40
Do not perform any preparatory actions for repeated opening. Then, when the timer 763 measures a certain period of time t1, its output becomes low level, and the opening/closing plate 41 is closed.

Next, when a specific game state is reached, which is a feature of this embodiment, that is, a combination of the display states of the rotating drums 51a to 51C is in a predetermined state that can provide the maximum value (for example, all A symbols are displayed). The operation when the display state of the segment display 50B becomes 7 will be explained below.

A determination circuit 645 derives a high level signal indicating that a specific gaming state has been established and supplies it to an AND gate 646. At this point, the AND gate 646 is supplied with the low level output of the predetermined value input state detection circuit 66 inverted to a high level, so a high level determination signal jO is derived from the AND gate 646. Judgment signal, jO
sets flip-flop 766. Therefore, when a specific gaming state is entered, only the display state of the small rotating drums 51a to 51c (previously) is operated in accordance with the judgment signal jl, and the operation that would be performed when the maximum value is given is performed. A repeat value imparting operation is performed based on the gaming state. That is, the timer 763 derives a high level for a certain period of time t1 from when the determination signal J1 is applied, and outputs the high level to the driver 7.
5 to open the opening/closing plate 41. At this time, AND gate 651 is activated by the set output of flip-flop 766. When the hit ball hits either the winning area 43a or 43C, it is detected by the detection switch 471b. Detection switch 4
The detection output of 4b is given to a counter 652 via an AND gate 651. The counter 652 counts the number of winning balls in the winning areas 438 to 43C in a specific gaming state, and provides the counted value to the comparison circuit 653 and the numerical information display drive circuit 67. The comparison circuit 653 is a setting section 654
The number of winning balls that can be won into the variable winning ball device 40 (for example, 10) is given as a reference input in the specific game state set in . Comparison circuit 653 derives a low level signal when the count value of counter 6571 is smaller than a set number. This low level signal is inverted to high level by an inverter 655, and
Since the base input of transistor 76
4 supplies the high level signal of the output of the timer 763 to the OR gate 71.

Further, the count value of the counter 652 is displayed on the numerical information display 6 by the numerical information display drive circuit 67. By looking at the display state of the numerical information display 6, the player can know the number of winning balls during the development period of the variable player prize ball device 40 in a specific game state, and also how many winning balls are allowed. You can easily find out if there are any. Therefore, based on this display, the player has the advantage of being able to easily formulate a strategy for the game.

If there is a predetermined number of allowed winning balls before the timer 763 times up, the comparison circuit 653 derives a high level signal. This high level signal is transmitted to inverter 6
55 to a low level signal, and the transistor 764
is turned off, and the high level output of timer 763 is not derived. In this way, when the specific gaming state is entered, when the number of winning balls in the winning area reaches a predetermined number before the one-move time t1 set by the timer 763 has elapsed, the solenoid 451 is forcibly turned off. The opening/closing plate 41 is closed. At this time, the output of the inverter 655 is applied to a falling differentiation circuit 767 via an OR gate 765, and is differentiated into falling.

This differential pulse is then given to the monostable multi 768, and the monostable multi 768 derives a high level signal for a certain period of time. The output is applied to AND gates 769 and 76a, and causes flip-flop 761 to be reset.

By the way, when a ball enters the winning area fi 438 during the period in which the variable winning ball device 10 is driven to open after the specific game state, the detection switch 44 outputs a detection output and sets the flip-flop 76b. For this reason,
AND gate 769 must have a set output from flip 70 knob 766 (that is, be in a specific game state)
, there is a setting force applied to the Noritsubu flop 76b (that is, a condition that can repeatedly open the variable winning ball device 40 is detected), and there is an output of the monostable multi 768 (that is, when the variable winning ball device 40 is opened). Based on this, a high level signal is derived, and the high level signal is applied to a timer 763 via an OR gate 762. In response, the timer 763 again starts counting operation for a certain period of time t1, and derives a high level signal during that period. This high level signal is transmitted to the transistor 764 and the OR gate 71.
The solenoid 451 is energized. Therefore, after entering the specific gaming state, as long as the repeating condition is detected, the variable winning ball device 40 is repeatedly activated.
is opened and driven.

In addition, after a certain time delay from the output of the monostable multi-768,
A delay circuit 76G is configured to reset seven lip-flops 76b. In this case, the reset output of the flip-flop 76b is given to the AND gate 76a, but at this time, the output of the monostable multi 768 is no longer given as the other input of the AND gate 76a, so the AND gate 76a is at a high level. No signal derived.

Thereafter, in the same way, after the specific gaming state, one cycle is defined as a certain period of time [1 (for example, 30 seconds) or until a predetermined number (for example, 10) of winning balls allowed during one opening period are generated. As long as there are winning balls in the winning area 43a,
The cycle repeats. Therefore, in the pachinko game machine 10 where the number of prize balls for deferred payment is limited once it enters a specific gaming state, the number of winning balls during one opening period of the variable winning ball device 40 is limited to a predetermined number. There are advantages such as being able to repeat the winnings many times, allowing the player to maintain an advantageous state for a long time, and enlivening the atmosphere of the game.

In addition, when the variable winning ball device 40 is repeatedly driven to open and open, if no ball enters the winning area 43'a, the flip-flop 76b remains reset. Therefore, in this case, monostable multi 768
The AND gate 76a derives a high level signal according to the output of the flip-flop 7 via the ORGEL door 6d.
66 is reset. As a result, the variable winning ball device 40
The repeated opening drive operation of is completed.

After the specific game state, each time the variable winning ball device 4o is repeatedly driven to open, when a ball enters the member area 43a,
The repeated production of the variable winning ball device 40 continues. However, when the predetermined value (-1) state detection circuit 6G receives a predetermined number of prize balls (for example, 200
If it is detected that a payout (0 pieces) has been paid out, the detection output is given to the Noritsubu flop 766 via the OR gate 76d, and the flip-flop 766 is reset.

This also ends the repeated opening/closing driving operation of the variable winning ball device 40.

Note that in this embodiment, the predetermined value is set to the state detection circuit 66.
The detection output is derived when a fixed number of prize balls are paid out, but the predetermined value imparting state detection circuit 66 counts the number of times the variable winning ball device 40 is repeatedly opened, and determines whether the number of times is a fixed number or not. For example, the configuration may be such that the detection output is derived when the 18th time has been reached.

Furthermore, in the above-mentioned embodiment, as the repetition condition detection means,
Although a case has been described in which there is one or more winning balls in the winning area 43a during the opening period of the variable winning ball device 40 in the specific gaming state, other repeating conditions may be detected. For example, if the number of balls that have won a prize in any of the winning areas 438 to 43C is smaller than the number of balls (for example, 10) detected by the predetermined number of winning balls detection circuit 65, for example, 3
It may be configured such that the repetition condition is detected when there are more than 1). In that case, a comparison circuit is separately provided to detect that the counter 652 has counted the small number of winning balls (3), and the output of the comparison circuit is used to connect the flip-flop 76b.
The configuration may be configured so that .

Furthermore, in the above embodiment, the rotating drum display mechanism 5
Although the specific gaming state is determined based on the combination of the displays of 0A and the segment display 50B, the specific gaming state may be determined based only on the display of the rotating drum display euiis6A. That is, the segment display 50B can also be made not to be used for determining a specific gaming state. In this way, the probability of entering a specific gaming state is increased, making it possible to provide a pachinko gaming machine that can improve the service provided to players.

Further, as another embodiment of the drive circuit 70, an AND gate is provided between the OR gate 71 and the driver 75, and a pulse with a fixed time interval (for example, 2 seconds) is applied to the other input of the AND gate, thereby making it possible to control the variable winning balls. The device 40 may be driven open and closed within a relatively long period of time.

In the embodiments shown in FIGS. 6 and 7 described above, a case was shown in which a hardware circuit was used to explain the present invention in detail, but the technical idea of the present invention is that it is constructed by program processing using a microprocessor. You can also do it. In that case, the program settings can be changed so that the circuits shown in FIGS. Explanation will be omitted.

[Effects of the Invention] As described above, according to the present invention, in a pachinko game machine that can generate a large number of winning balls at a relatively high rate based on a specific game state, the variable winning ball device is fixed at a constant rate. It can be driven to a state where it is easy to win for a certain amount of time or until a certain number of winning balls is generated, and the number of winning balls for each machine or for each player when the variable winning ball device is in a state where it is easy to win. This has the unique effect of being able to limit the variation in values within a certain range. In addition, since it is possible to limit the variation in the number of winning balls when the variable winning ball device is in a state where it is easy to win, it is possible to equalize the winnings to many players without giving a large amount of prize balls only to a specific player. It is also effective - Furthermore, when the variable winning ball device is made to be in a state where it is easy to win after a certain gaming state, if the repeat condition is satisfied for a certain period of time or until a certain number of winning balls occur, the variable winning ball device will be repeatedly won. The ball device can be placed in a state where it is easy to win a prize many times, and the player can play the game in a state where it is easy to win a prize for a relatively long period of time, thereby providing an effect that the player can enjoy a thrilling feeling for a long time.
