Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pachinko game machine, and more specifically, the present invention relates to a pachinko game machine that can freely change into a first state that is advantageous to the player and a second state that is disadvantageous to the player. This invention relates to a pachinko game machine in which a variable prize winning ball device is arranged on a game board.

[Prior Art] In general, pachinko gaming machines that use pachinko balls to play games are widely used and are popular among players as a convenient form of leisure. As is well known, pachinko machines have multiple safe holes and winning ball devices (Yakumono, Yakumono, etc.) on their game boards.
When a player hits a pachinko ball with a pachinko ball (commonly known as tulip), if the ball lands in a safe hole or a yakumono with a probability of forming a ball, a certain number of prizes will be released. Conventional pachinko machines, for the purpose of providing services to players, would open a predetermined number of Yakumonos or open Yakumonos for a short period of time when a ball landed in a specific safe hole or winning area. . For this reason, conventionally, even if prizes are awarded depending on the gaming state, a predetermined number of Yakumono are only created for a short period of time based on winnings in a specific winning area, so players do not use pachinko machines. If you want to win a large amount of prizes by playing the game until you stop playing, you need excellent gaming skills and the endurance to play continuously for a long time. For this reason, many of the players who won a large amount of prizes on a single pachinko game machine before being controlled to stop were skilled players known as "bachi players." However, there is a desire for gaming halls to provide many players with the opportunity to win a large amount of prizes.

[Problems to be solved by the invention] Therefore, the applicant of the present application previously filed Japanese Patent Application No. 54-145643.
No. 54-145644 discloses a pachinko machine in which a variable winning ball device such as a Yakumono is made easy to win for a relatively long period of time based on a specific gaming state, and a large amount of prizes can be won at once. I proposed a gaming machine. However, in the previously proposed system, the variable winning ball device is simply set in a state where it is easy to win for a relatively long time, so the variable winning ball device is controlled by the adjustment state of the nail installed near the variable winning ball device. During one opening period of the device, there were cases where more than a dozen winnings occurred, and there were cases where there were almost no winnings, and the winning probability varied more than expected depending on the machine. Therefore, there is a demand for a pachinko gaming machine that can limit the number of winning balls that can be won within one opening period of the variable winning ball device to a relatively large fixed number.

Furthermore, the previously proposed pachinko game machine opens the variable winning ball device for a certain period of time based on a specific game state, closes it once, and then opens it again based on conditions that allow it to be opened repeatedly. However, since there is no restriction on the number of winning balls that can be won during the period when the variable winning ball device is opened once, if many winnings occur at once, the winnings will be stopped relatively quickly, and the player will not be able to win. In some cases, it was not possible to satisfy the desire to play the game for as long as possible with good probability.

In view of the above circumstances, the present invention makes it easier to win with a variable winning ball device for a relatively long time based on a specific gaming state, and in which it is possible to win a prize during the period when the variable winning ball device is made easier to win. A pachinko game machine that limits the number of balls to limit the variation between pachinko machines to within a certain range, making it possible to reduce the variation in the number of prize balls awarded when a specific gaming state is reached compared to conventional pachinko machines. The purpose is to provide

[Means for Solving the Problems] A pachinko game machine according to the present invention is a pachinko game machine that includes a game board on which a winning area is formed, which is arranged on the game board and is advantageous for the player. A variable winning ball device that can freely change between a first state and a second state that is disadvantageous to the player, and a pachinko gaming state determined such that the variable winning ball device can change to the first state for a certain period of time. specific game state detection means for detecting that the variable winning ball device is in the first state, the number of winning balls entered into the variable winning ball device reaches a certain number allowed within the certain period; a predetermined number of winning balls detecting means for detecting this, and driving the variable winning ball device to the first state according to the output of the specific game state detecting means, and controlling the output of the predetermined number of winning balls detecting means within the certain period of time. The present invention is characterized in that it includes a drive control means for driving the variable winning ball device to the second state in response to the occurrence of a certain number of winning balls or when there is no output from the predetermined number of winning balls detecting means and a certain period of time has elapsed.

[Operation] The variable winning ball device is set to a first state advantageous to the player based on a specific game state, and when the number of winning balls during the period of the first state reaches a certain number allowed or a certain number. When a certain period of time has elapsed without reaching the player, the variable winning ball device changes to a second state that is disadvantageous to the player.

The mounting plate 31 is provided with display windows 33a, 33b, and 33c for displaying identification information drawn on the rotating drum included in the rotating drum display mechanism 50A.

Further, a frame member 34 is attached to an upper position of the mounting plate 31. The frame member 34 is equipped with a segment display 50B,
An inverted V-shaped ball receiving plate 341 is formed on its upper part.

The balls received by the ball receiving plate 341 are guided to the back side through a hole that becomes the winning area 3a. A passage area 342 for passing the ball is provided in a laterally extending portion of the frame member 34.
343 is formed. Furthermore, a plurality of obstruction nails 35 are installed in the mounting plate 31 at the upper position of the opening 32.

A guide member 36 is installed between the obstruction nail 35 and the opening 32. The guide member 36 is provided at multiple locations in the lateral direction.
A guide plate is formed along the vertical direction, and works to guide the ball vertically and allow it to fall.

The variable prize winning ball device 40 opens the opening/closing plate 41 to the front to accept balls as a first state that is advantageous to the player, and closes the opening/closing plate 41 as an example of a second state that is disadvantageous to the player. This makes it impossible to accept balls. More specifically, a variable winning ball device 40 is provided in relation to the opening 32. The variable winning ball device 40 is located on the front surface of the frame member 42 (i.e., the portion related to the opening 32).
An opening/closing plate 41 is rotatably attached to the opening/closing plate 41. That is, triangular side walls 411 and 412 are formed on both sides of the opening/closing plate 41. The side walls 411, 412 are rotatably supported on the side portions of the frame member 42 by shafts 414. Paths 421 and 422 are formed below the frame member 42. The back side of the frame member 42 is covered with a cover 423. When the opening/closing plate 41 is opened, the opening 32 becomes a winning area 43 where balls can be won. The winning area 43 includes a plurality of winning areas 43a in the horizontal direction.
~43c. In the winning area 43a, conditions are determined such that the opening/closing plate 41 can be opened again by a winning ball during the opening of the opening/closing plate 41 in a specific game state, and the variable winning ball device 40 can be brought into a state where it is easy to win a prize. For that purpose,
The winning ball in the winning area 43a is guided to the back side and detected by a detection switch 44a, which is an example of specific game state detection means provided below. The winning balls in the winning areas 43a to 43c are guided downward via paths 421 and 422, respectively. A detection switch 44b is provided below the paths 421, 422 for detecting a winning ball in any winning area.

An opening/closing drive mechanism 45 is provided in relation to the opening/closing plate 41. The opening/closing drive mechanism 45 is constructed by connecting a part of a T-shaped lever 453 to a plunger 452 of a solenoid 451. The lever 453 is rotatably supported at its center by a pin 454 fixed to the mounting plate 31. lever 453
One end of the rod 455 is engaged with one end of the rod 455 . The other end of the rod 455 is connected to a pin 4 formed on the side wall of the opening/closing plate 41.
Connected with 13. The other end of the short side of the lever 453 is the spring 4
It is tension-biased at 56. This allows solenoid 4
When the lever 51 is electrically deenergized, the lower end of the lever 453 is pulled by the spring 456, and the tip of the long side is pulled down, thereby closing the opening/closing plate 1. This means that when the solenoid 451 is energized, the lever 4
53 rotates clockwise and pulls up the rod 455 to open the opening/closing plate 41 to the front.

In addition, in the illustration, as an example of a variable winning ball device, a variable winning ball device is shown that can be changed into a state in which it is easy to win a ball as a state that is advantageous to the player, and a state in which it is not possible to win a ball as a state that is disadvantageous to the player. It goes without saying that various other variable winning ball devices may also be used. For example, as another example of a variable winning ball device, like the so-called tulip, a pair of ball receiving pieces are opened on the left and right to make it easier for the player to win the ball, which is advantageous to the player. As a disadvantageous state, the ball receiving piece may be closed to make it difficult to win a ball, and as another example of the variable winning ball device, it can be opened to the front of the game board 1. A ball entrance for receiving one ball is formed at the top of the opening/closing plate, and the opening/closing plate is closed during normal gaming conditions, and the opening/closing plate is opened based on the gaming status. It may be configured as follows.

Next, details of the variable display device 50 will be described. Variable display device 50 includes a rotating drum display mechanism 50A and a segment display 50B. The rotating drum display mechanism 50A is constructed as shown in FIG.

That is, the rotating drum group 51 includes a plurality of rows of rotating drums 5.

Ratchet gears 52a to 52C (only 52c is shown in the figure) having the number of teeth corresponding to the number of identification information drawn on the outer periphery are fixed. Rotating drums 51a to 51c in each row
Each of the drum shafts 53 is loosely fitted onto the drum shaft 53 and is supported so as to be individually rotatable by its frictional force. drum shaft 53
is pivoted on both sides of the box 54. A gear 551 included in the rotational force transmission mechanism 55 is fixed to one end of the drum shaft 53. The gear 551 is a gear change gear 55
2 and are interlocked and connected. A motor 56 for driving the rotating drum is mounted on the side of the box 54.

A geared motor is used as the motor 56, and its driving gear is coupled to the gear 552. The rotational force of the motor 56 is transmitted to the drum shaft 53 via gears 552 and 551, and drives the rotating drum group 51 to rotate. Further, on the rear back surface of the box 54, each row of rotating drums 51a to 51
Solenoids 57a to 57c are fixedly attached thereto to individually control rotation or stop of each of c. Plungers 571 of these solenoids 57a to 57c are connected to one ends of locking levers 58a to 58c, respectively, by pins. Approximately central portions of these locking levers 58a to 58c are supported by a shaft 581. Both sides of the axis 581 are box 5
It is fixed on both sides of 4.

A claw-like portion 582 is formed at the tip of each of the locking levers 58a to 58c. The claw-like portions 582 of each of the locking levers 58a-58c are attached to the corresponding ratchet gears 52a-52.
c to lock each row of rotating drums;
Keep locked.

The specific game state that allows the variable winning ball device 40 to be in the first state for a relatively long time is a combination of identification information such as a picture pattern in each row displayed on the rotary drum display mechanism 50A. It is determined by the combination of the alignment state and the display state of numerical information displayed on the segment display 50B.

In addition, as other examples of the specific game state, only the display state of the rotating drum display mechanism 50A or the display state of the segment display 5
This may be based only on the display state when a plurality of 0B digits are provided, or based on the case where there are balls that have passed through a specific winning area provided on the game board 1.

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 rotary drum drive control circuit 62, a display drive circuit 63, a specific game state detection circuit 64, and a predetermined number of winning balls which is an example of a predetermined number of winning balls detection means. It includes a detection circuit 65, a predetermined value provision state detection circuit 66, a numerical information display drive circuit 67, and a drive control circuit 70.

Here, the variable display enable condition detection circuit 61 detects a condition that allows the variable display device 50 to display a variable display.

The rotating drum drive control circuit 62 drives and controls the rotating drum display mechanism 50A based on variable display enable conditions. The display drive circuit 63 drives the segment display 50B to display based on variable display enable conditions.

The specific game state detection circuit 64 is the rotating drum display mechanism 50A.
Based on the combination of the display state of , and the display state of the segment display 50B, it is detected that a predetermined specific gaming state has been entered. In addition, the specific gaming state detection circuit 65 preferably includes a function of detecting not only the specific gaming state but also other gaming states and a condition that allows the variable prize winning ball device 40 to be in the first state. The predetermined number of winning balls detection circuit 65 detects that there is a predetermined number of balls that can be won in the variable winning ball device 40 in a specific game state. The predetermined value provision state detection circuit 66 detects a state in which a predetermined value is provided in a specific gaming state (for example, a state in which a relatively large number of electric balls set as the number of terminations is provided).

FIG. 7 is a detailed circuit diagram of the drive control circuit 70 and the predetermined winning ball number detection circuit 65. This drive control circuit 70 is
It includes an OR gate 71, timers 72 to 74, a driver 75, and a repetitive opening/closing drive circuit 760 for a certain period of time. here,
The driver 75 activates the variable winning ball device 40 by energizing the solenoid 451 during the output period of the OR gate 71.
is driven to the first state. The driving circuit 760 repeatedly opens and closes for a relatively long period of time (for example, t) as an example of bringing the variable winning ball device 40 into the first state.
1-30 seconds) to make it easier to win continuously.

Next, with reference to FIGS. 1 to 7, specific operations when playing a game with the pachinko game machine 10 of this embodiment will be described. The player puts the balls borrowed from the ball rental machine into the ball waiting gutter 13, rotates the ball hitting handle 14 to adjust the strength of the ball, and then presses the ball hitting switch 14S. Batting switch 14s
Electric power is supplied to the motor 241 in response to the press. In response, the motor 241 is rotated and the ball hitting hammer 243 is rotated intermittently, thereby hitting the balls into the game board 1 one by one. In this way, when the player is playing a ball hitting game, the ball is placed in the safe holes 2a to 2C or in the yakumono 4a, 4.
When one of the winning balls is won, the prize ball discharging mechanism is activated to control the release of a predetermined number of prize balls for each winning ball. On the other hand, when a hit ball enters any of the winning areas 3a to 3C, the corresponding detection switches 22a and 22b derive a high level and provide it to the drive circuit 621 via the OR gate 611 and also to the timer 622. Furthermore, the output of the OR gate 611 causes a flip-flop 631 included in the display drive circuit 63 to be set. In response, the drive circuit 621 energizes the solenoids 57a-57c to disengage the claw-like portions 582 of the locking levers 58a-58C from the corresponding ratchet gears 52a-52c, and rotationally drives the motor 56. By doing so, the rotating drums 51a to 51c in each row are rotationally driven and the display state of the rotating drums is varied. At the same time, flip-flop 6
31 set output 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
A clock pulse is derived in response to the set output of 1 and is applied to the ring counter 634. The ring counter 634 is
In response to the input of the clock pulse, the segment indicator 50
It cyclically counts the numerical values O to 9 that can be displayed in B, and provides the counted value to the decoder driver 635 and the determination circuit 645 included in the specific game state detection circuit 64.

The decoder driver 635 decodes the count value of the ring counter 634, and based on the count value, sequentially changes the numerical value displayed on the segment display 50B in synchronization with the cycle of the clock pulse.

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

In the state where the rotating drums 5ia to 51c and the segment display device 50B are displaying variables as described above, the player can set the combination of display states of the rotating drums 51a to 51c in each row to a specific game state. Press the stop command switch 17. Note that if the stop command switch 17 is not pressed within a certain period of time set by the timer 622 after starting variable display, a stop command is issued by the output of the timer 622. In response, the drive circuit 621 deenergizes the solenoids 57a-57c in a predetermined order (or in an irregular order) to sequentially stop the rotating drums 51a-51c. The drive circuit 621 then stops the rotation of the motor 56 after a short delay, and also derives a high-level signal indicating that all rotating drums have stopped. This high level signal is applied to the flip-flop 631
is reset, and is also given to the display state determination circuit 643 as a determination command signal. In response, AND gate 632 stops deriving clock pulses. For this reason,
The count value of ring counter 634 is not incremented, and therefore a number corresponding to the count value being counted by ring counter 634 is displayed on continuous segment display 50B.

The display state determination circuit 643 determines the combination of identification information displayed on the rotating drums in each row based on the outputs provided from the sensors 641 and 642 in response to the determination command signal. By the way, as the sensors 641 and 642, for example, a photoelectric sensor having a light projecting section and a light receiving section is used. The light emitting part and the light receiving part of each sensor 641 and 642 are provided facing each other on both axial sides of the rotating drums of all rows. Although not shown in FIG. 5, on each side surface of the rotating drums 51a to 51c, first circles with different radii and angles corresponding to the identification information displayed on each rotating drum are formed. At the position on the circumference and the second circumference,
A portion with a through hole and a portion without a through hole are provided. As a result, four types of identification information can be identified by combining portions with and without holes.

For example, if the part with a hole is set to logic "1" and the part without a hole is set to logic "0", then 4
2-bit code of type roof.

rolJ, rlOJ, and rlN, it is possible to detect the combination of identification information of the rotating drums in each row. Then, the display state determination circuit 643
A score is determined based on the combination of identification information displayed in 1a to 51c, and the score is provided to the drive control circuit 70 and the determination circuit 645.

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 The state 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
are the corresponding judgment signals j2. Depending on the inputs of j3, j4, a predetermined period of time t2, t3. A high level signal is derived for only t4. Here, timer 7
The fixed time set in 2 to 74 is t2≧t3≧t
For example, t2-10 seconds, t3-6 seconds, and t4-4 seconds are selected. Note that if the determination signal is other than j1 (that is, j2 to j4), the determination circuit 645 does not determine the display state of the segment display 50B at all.

Now, for example, the display state determination circuit 643 receives the determination signal j2.
Assuming that the timer 72 is derived for a certain period of time t
A high level signal of 2 is derived.

This high level signal is applied to the driver 75 via the OR gate 71. Accordingly, the driver 75 operates for a certain period of time t.
2 continuously energizes the solenoid 451. Therefore, the opening/closing plate 41 of the variable winning ball device 40 is opened for a certain period of time t2, allowing the ball to win. When a ball enters the winning area 43b or 43c, the prize ball releasing mechanism releases a predetermined number of prize balls depending on the winning ball. However, even if a ball enters the winning area 43a, the opening operation of the variable winning ball device 40 is not extended and only a predetermined number of prize balls are released 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 643 derives the determination signal j1 and provides it to the determination circuit 645, and also provides it as a set input to the flip-flop 761.

Accordingly, flip-flop 761 is set.

Further, the determination circuit 645 determines, in accordance with the determination signal j1, that the count value of the ring counter 634 is in a display state (for example, 7
is displayed). At this time, the determination circuit 645 determines that even if the combination of display states of the rotating drums 51a to 51c gives the maximum value,
Unless the segment display 50B is displaying 7, the maximum value imparting command signal jO (high level!/) is not derived.

In this case, the set output of flip-flop 761 set by determination signal j1 is given to timer 763 via OR gate 762. In response, timer 763 starts operating for a certain period of time t1, and during that period a high level signal is derived and applied to the collector of transistor 764. At this time, the mismatch output (low level) of the comparator circuit 653 is connected to the base of the transistor 764 by the inverter 6.
55, it is inverted to high level and given. For this reason,
Transistor 764 is conductive while comparator circuit 653 is outputting a non-coincidence output, and provides the output of timer 763 to driver 75 via OR gate 71 . In response, the driver 75 energizes the solenoid 451 to open the opening/closing plate 41. In this case as well, the flip-flop 766
is not set, AND gates 651 and 767 remain disabled. Therefore, the predetermined winning ball number detection circuit 65 does not count the balls that have won into the winning areas 43a to 43C, and therefore does not perform a preparation operation for repeatedly opening the variable winning ball device 40.

Then, when the timer 763 measures a certain period of time t1, its output is set to a low level, so that the opening/closing plate 41 is closed.

Next, when a specific gaming state is reached, which is a feature of this invention, that is, the combination of display states of the rotating drums 51a to 51c becomes a predetermined state that can give the maximum value (all display states with the symbol A), and When the display state of the segment display 50B reaches a state where 7 is displayed, the following operation is performed. That is, the determination circuit 645 derives a high level signal indicating that a specific gaming state has been established and supplies it to the AND gate 646. At this time, since the low level of the output of the predetermined value provision state detection circuit 66 is inverted to the high level and is applied to the AND gate 646,
A high level judgment signal jO is derived. This judgment signal j
O causes flip-flop 766 to be set. Therefore, when a specific gaming state is entered, only the display state of the rotating drums 51a to 51c described above is operated in accordance with the determination signal j1, and then the operation is repeated based on the specific gaming state. A value adding operation is performed. That is, the timer 763 derives the noise level for a certain period of time t1 from the time when the judgment signal j1 is applied, and outputs the noise level to the driver 75.
is driven to open the opening/closing plate 41. At this time, AND gate 651 is activated by the set output of flip-flop 766. Therefore, when a ball is hit into any of the winning areas 438 to 43c, it is detected by the detection switch 44b. The detection output of the detection switch 44b is sent to a counter 652 via an AND gate 651.
given to. The counter 652 counts the number of winning balls in the winning areas 438 to 43c after a specific gaming state,
The counted value is given to the comparison circuit 653 and the numerical information display drive concave path 67.

The comparison circuit 653 is given as a reference input the number of winning man-hours (for example, 10) that can be won to the variable winning ball device 40 in the specific gaming state set by the setting section 654. Comparison circuit 653 derives a low level signal when the count value of counter 654 is smaller than a set number. This low level signal is inverted to high level by inverter 655 and applied as the base input of transistor 764, so transistor 764 provides the high level signal of the output of timer 763 to OR gate 71. Also, counter 6
The count value of 52 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 opening period of the variable winning ball device 40 in a specific game state, and how many winning balls are allowed. You can also easily find out what is happening.

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. Since this high level signal is inverted to a low level signal by the inverter 655, the transistor 764 is turned off and the high level signal of the timer 763 is not derived. In this way, when a specific gaming state is entered, the fixed time t1 set by the timer 763
If the number of winning balls in the winning area reaches a predetermined number before the time elapses, the solenoid 451 is forcibly deenergized and the opening/closing plate 41 is closed. At this time, the output of the inverter 655 passes through the OR gate 765 to the differential circuit 767.
is given to , and differentiated in the falling direction. This differential pulse is applied to a monostable multi 768. The monostable multi 768 derives a high level for a certain period of time, provides its output to the AND gate 769.76a, and resets the flip-flop 761.

By the way, when a ball enters the winning area 43a during the period when the variable winning ball device 40 is being driven to open after the specific game state, the detection switch 44a outputs a detection output to set the flip-flop 76b. For this reason,
AND gate 769 indicates that there is a set output of flip-flop 766 (that is, a specific gaming state)
, there is a set output of the flip-prop 76b (that is, a condition that can repeatedly open the variable winning ball device 40 has been detected), and there is an output of the monostable multi 76g (that is, the variable winning ball device 40 has been opened). Based on this, a high level signal is derived and the OR gate 76
2 to the timer 763. Timer 76
3 starts counting operation for a certain period of time t1 again, and during that period a high level signal is derived and applied to the driver 75 via the transistor 764 and the OR gate 71. As a result, after entering the specific gaming state, the detection switch 44a
As long as the repeating condition is detected, the variable winning ball device 40 is repeatedly driven to open. In addition, monostable multi 768
The delay circuit 76c resets the flip-flop 76b after a certain period of time delay from the output of the flip-flop 76b. In this case, the reset output of the flip-flop 76b is given to the AND gate 76a, but since the output of the monostable multi 768 is not already given as the other input of the AND gate 76a,
AND gate 76a does not derive a high level signal.

Thereafter, in the same way, after the specific game state, as long as there are winning balls in the winning area 43a, the variable winning ball device is repeatedly operated for a certain period of time t1 or until a predetermined number of winning balls allowed during one opening period are generated. 40 can be driven open. by this,
In a pachinko gaming machine 10 in which the number of prize balls to be paid out after entering a specific gaming state is limited, the number of winning balls during one opening period of the variable winning ball device 40 is limited to a predetermined number or less, One advantage is that it can be repeated a large number of times. Further, the predetermined number of winning balls detecting circuit 65 and the drive control circuit 770 drive the variable winning ball device to the first state according to the output of the specific gaming state detecting means, and the predetermined winning balls are set within the certain period of time. A drive control means is configured to drive the variable winning ball device to a second state in response to the presence of an output from the number detecting means or the fact that there is no output from the predetermined number of winning balls detecting means and a certain period of time has elapsed.

Note that when the variable winning ball device 40 is repeatedly driven to open and open, if no ball enters the winning area 43a, the flip-flop 76b remains reset. In this case, the AND gate 76a derives a high level signal according to the output of the monostable multi 768,
Flip-flop 766 is reset via OR gate 76d. As a result, the repeated opening and driving operation of the variable winning ball device 40 is thereafter terminated.

Furthermore, after the specific game state, each time the variable winning ball device is repeatedly driven to open and a ball repeatedly enters the winning area 43a, the repeated opening operation of the variable winning ball device 40 is continued. However, when the predetermined value provision state detection circuit 66 detects that a relatively large fixed number of prize balls have been paid out, the detection output resets the flip-flop 766 via the OR gate 67d. This also ends the repeated opening/closing driving operation of the variable winning ball device 40.

In addition, 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 after the specific game state, other repeating conditions may be detected. For example, if the number of winning balls in any of the winning areas 43a to 43c is smaller (for example, 3 balls) than the number of balls (for example, 10 balls) detected by the predetermined winning ball number detection circuit 65, It may be configured to detect repetition conditions. In that case, a comparison circuit may be separately provided to detect that the counter 652 has counted a relatively small number of winning balls (3 pieces), and the flip-flop 76b may be set by the output of the comparison circuit.

Furthermore, in the above-mentioned embodiment, a case has been described in which the repetitive condition detecting means is provided and the drive control means repeatedly drives the variable winning ball device 40 to open in response to the detected repetitive condition. It's okay. In that case,
Either when the time during which the variable winning ball device 40 is opened and driven in a specific gaming state is significantly lengthened, and a predetermined number of winning balls (for example, 50 balls) is detected within that time, or when a relatively long fixed period of time has elapsed. Variable winning ball device 4
0 may be closed.

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.

By the way, although the embodiments shown in FIGS. 6 and 7 described above show a case in which a hardware circuit is used to achieve the operation of the present invention, the technical idea of the present invention is to implement program processing using a microprocessor. You can also do it. In that case, a person skilled in the art would easily be able to set a program to perform the operations of the circuits shown in FIGS. 6 and 7, so a detailed explanation thereof 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 with a relatively high probability based on a specific gaming state, the variable winning ball device is fixed at a constant rate. It can be driven to a state in which it is easy to win for a certain amount of time, or it can be driven in a state in which it is easy to win until the number of winning balls reaches a certain number. Unique effects such as being able to limit the variation in the number of balls within a certain range are produced.Also, 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 limit the variation in the number of winning balls to a specific player. This also has the effect of uniformizing the services provided to many players without awarding prize balls.
