Description

[Detailed Description of the Invention] This invention relates to a pachinko game machine, and in particular, a pachinko game machine that releases winning balls corresponding to the number of winning balls in response to winning balls exceeding a certain number entering a variable winning ball device. Regarding.

In general, pachinko gaming machines that use pachinko balls to play games are widely used and are popular among players as one of the convenient cash registers. As is well known, a pachinko game machine has multiple safe holes and a winning ball device (Yakumono, commonly known as chulip) on its game board.
is set up, and when a player hits a pachinko ball,
If a ball lands in the safe hole or the Yakumono with a certain probability, a certain number of prize balls will be released. Conventional pachinko machines, for the purpose of providing services to players, open a predetermined number of yakumonos when a ball lands in a specific safe hole or winning area, or open a certain yakumono for a short period of time. Ta.
For this reason, conventionally, even if prize balls are awarded depending on the gaming state, a predetermined number of Yakumono are only created for a rectangular period of time based on the winning balls in a specific winning area, so the player cannot play Pachinko. If you want to win a large amount of prize balls by playing until the machine stops, you need excellent gaming skills and the patience to play continuously for a long time. For this reason, many players known as pachinko players were able to win a large number of prize balls on a single pachinko machine until the game was stopped. However, there is a desire for a gaming hall to provide many players with the opportunity to win a large amount of prize balls.

Therefore, the applicant of this application first filed the patent application No. 54-145643.
No. 54-145644, a variable winning ball device such as a Yakumono is set in a state where it is easy to win for a relatively long time based on a specific gaming state, and 1.
We proposed a pachinko game machine that allows you to win a large number of prize balls each time. However, with the previously proposed variable winning ball device, there are some that produce more than a dozen winning balls during one opening period, and others that have almost no winning balls, and the winning probability may be higher than expected depending on the machine. This caused variations in the amount of data. For this reason, 1 of the variable winning ball device
There is a demand for a pachinko game machine that can limit the number of winning balls that can be won within a game opening period to a relatively large fixed number.

Therefore, as a further improvement, the applicant of the present application has developed a variable winning ball device based on specified conditions to make it easier to win a prize based on a specific gaming state and to repeatedly bring the variable winning ball device into a state where it is easier to win a prize. In a pachinko machine that makes it easier to win a prize again, it is possible to increase the number of times a variable winning ball device can be used to make it easier to win a prize depending on a specific gaming state, and allows a player to play for as long as possible with a good winning probability. I proposed a gaming machine. Such pachinko gaming machines are approved as meeting the manufacturing permit standards for gaming machines and the like.

However, in the pachinko game machine as described above, when the variable winning ball device is set in an advantageous state for the player, the number of winning balls in the variable winning ball device sometimes exceeds a certain number. In this case as well, the pachinko game machine not only releases prize balls corresponding to a certain number of winning balls, but also releases prize balls corresponding to winning balls exceeding a certain number. For this reason, the pachinko game machine violates the permission standards, so it is desirable to prevent the pachinko game machine from discharging prize balls in response to the number of winning balls exceeding a certain number. In view of the above circumstances, the present invention provides a pachinko game machine equipped with a variable winning ball device that can generate many winning balls with a relatively high probability based on a specific gaming state, which is advantageous for players. To provide a pachinko game machine that can prevent the release of prize balls corresponding to the number of winning balls exceeding a certain number even if balls exceeding a certain number enter a variable winning ball device in a state where the number of winning balls exceeds a certain number. .

To summarize this invention, when a variable winning ball device is in a state where it is easy to win based on a specific game state, and when winning balls exceeding a certain number occur, the excess winning balls are invalidated. It is.

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

It is used to open the ball receiving pieces a and 4b. The outputs of the winning ball detectors 22a and 22b are used as detection outputs for the state in which the rotating drum display mechanism 50A and the segment display device 50B can be driven for display. A winning ball collection path 213 is provided on the back surface of the game board 1 at a position slightly above the out ball entrance 5. The path 213 has safe holes 2a, 2b,
Balls that have won in any of the winning areas 3a to 3c, the Yakumono 4a, 4b, or the variable winning ball device 40 are guided to the winning ball processing device 23.

The winning ball processing device 23 drops the winning balls guided from the path 213 into the meandering path 214 one by one. That is, the winning ball processing device 23 is a cylinder member 231
including. A ball receiving portion 232 is provided at one end of the cylindrical member 231.
is formed. The ball receiving portion 232 is connected to the meandering path 21
4 and receives winning balls passing through the meandering path 214. A protruding piece 233 is formed at the other end of the cylindrical member 231 . The cylindrical member 231 is swingably supported by a support member 234. In addition, the lever 2 has a hook 235 formed on the cylindrical member 231.

The winning ball processor 23 passes the winning balls through a meandering path 214 one by one.
The balls dropped are either driven by the prize ball release mechanism 24 or processed by the flow path switching mechanism 25. That is, the variable winning ball device 4 is released during one opening.
If the number of balls that have won 0 is less than a certain number, the dropped balls drive the prize ball release mechanism 24 to release the prize balls. The prize ball release mechanism 24 includes a lever 241. One end of the lever 241 is inserted into the downstream vertical portion of the meandering path 214 in order to place the balls dropped from the winning ball processor 23.
When a winning ball is placed on one end of the lever 241, the lever 241 rotates downward about the fulcrum 242 and acts to push up the vertical lever 243. A ball storage section 244 for storing a predetermined number of prize balls is provided above the vertical lever 243. A path 245 that guides prize balls to the prize ball discharge port 12 is formed below the ball storage section 244, and a path 245 that guides balls overflowing in the batted ball waiting gutter 13 to the surplus prize ball discharge port 15.

On the other hand, when the number of winning balls in the variable winning ball device 40 exceeds a certain number, the dropped balls are transferred to the flow path switching mechanism 2.
Processed in 5. The flow path switching mechanism 25 includes a flow path switching plate 251. The flow path switching plate 251 is formed on the bottom surface at a position in front of the lever 241 inserted into the downstream vertical part of the meandering path 214,
It is rotatably supported by a pin 252. A solenoid 253 is fixed to the upper part of the flow path switching plate 251. The solenoid 253 is energized when a detection switch 44b shown in FIG. 4A, which will be described later, detects winning balls exceeding a certain number. Flow path switching plate 2 on the side to which the solenoid 253 is fixed
A spring 254 is fixed to one end of 51. This is because when the solenoid 253 is energized to rotate the flow path switching plate 251 and then deenergized, the elastic force causes the solenoid 253 to return to its original state, in other words, to become a part of the meandering path 214. It's for a reason. The plunger 255 of the solenoid 253 is connected to the flow path switching plate 25

Next, with reference to Figures 3 to 5, the variable winning balls and
The configuration of the variable display device 30 will be explained. The variable winning ball/variable display device 30 is constructed by integrally mounting the variable winning ball device 40 and the variable display device 50 on a mounting plate 31. More specifically, the mounting plate 31 has an opening 32 formed therein. The opening 32 is selected to be a rectangular hole so that it becomes a winning area when the opening/closing plate 41 of the variable winning ball device 40 is opened. Also,
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. Additionally, a frame member 3 is provided at the upper position of the mounting plate 31.
4 is installed. A segment display 50B is attached to the frame member 34, and an inverted V-shaped ball receiving plate 341 is formed on the upper part of the segment display 50B. The balls received by this ball receiving plate 341 are guided to the back side through a hole that becomes the winning area 3a. The frame member 34 has passage areas 342, 3 in the horizontally extending portion for allowing the balls to pass through.
43 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 forms guide plates along the vertical direction at a plurality of locations in the lateral direction, and functions to allow the balls to fall while being guided in the vertical direction.

The variable winning ball device 40 opens the opening/closing plate 41 to the front to receive balls in a first state that is advantageous to the player, and in a second state that is disadvantageous to the player.
As an example of this state, the opening/closing plate 41 is closed to make it impossible to receive balls. To explain more specifically, the variable winning ball device 4 is connected to the opening 32.
0 is set. The variable winning ball device 40 is a frame member 4

An opening/closing plate 41 is rotatably attached to the opening/closing plate 41. That is,
Triangular side walls 411, 4 are provided on both sides of the opening/closing plate 41.
12 is formed. The side walls 411 and 412 are the shaft 41
3, it is rotatably supported on the side surface portion of the frame member 42. Paths 421 and 422 are provided below the frame member 42.
is formed. The back of the frame member 42 is a cover 423
covered with 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 4 in the horizontal direction.
It is divided into 3a to 43c. The winning area 43a is
Conditions are determined such that in a specific game state, the opening/closing plate 41 can be opened again by a winning ball while the opening/closing plate 41 is open, and the variable winning ball device 40 can be brought into a state where it is easy to win a prize. For this purpose, the winning ball in the winning area 43a is guided to the back side and detected by a detection switch 44a provided below. Winning area 43

In connection with the opening/closing plate 41, an opening/closing drive mechanism 45 is provided.
is provided. The opening/closing drive mechanism 45 includes a T-shaped lever 453 on a plunger 452 of a solenoid 451.
It is constructed by connecting parts of. The lever 453 is rotatably supported at its center by a pin 454 fixed to the mounting plate 31. At one end of the lever 453,
One end of rod 455 is engaged. Rod 455
The other end is 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 tension-biased by a spring 456. By this,
When the solenoid 451 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. Conversely, when the solenoid 451 is energized, the lever 453 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, there is a state in which balls are easily won as a state that is advantageous to the player, and a state that does not allow balls to win as a state that is disadvantageous to the player. However, it goes without saying that various other variable winning ball devices may be used. For example, as another example of a variable winning ball device, there is a so-called chulip, in which a pair of ball receiving pieces are opened on the left and right sides to make it easier for the player to win the ball, and the player can easily win the ball. As a disadvantageous condition for the player, the ball receiving piece may be closed to make it difficult for the player to win a prize.

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 multiple rows of rotating drums 51a, 51b, and 51c. Identification information such as a picture pattern, a symbol, or a number (for example, a picture pattern such as a bell, a star, a yacht, or a number or a symbol such as an alpha alphabet) is drawn on the outer periphery of the rotating drums 51a to 51c in each row. 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 to the respective side surfaces of the rotating drums 51a to 51c in each row. Rotating drum 51 in each row
Each of a to 51c is loosely fitted onto the drum shaft 53 and supported so as to be individually rotatable by its frictional force. The drum shaft 53 is pivotally supported on both sides of the box 54. A gear 551 included in the rotational force transmission mechanism 55 is provided at one end of the drum shaft 53.
is fixed. The gear 551 is meshed with a transmission gear 552. A motor 56 for driving the rotating drum is attached to the side surface of the box 54. The motor 56 is a geared motor,
The drive gear is coupled to 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. Furthermore, solenoids 57a to 57c are fixed to the rear rear surface of the box 54 for individually controlling rotation or stopping of the rotating drums 51a to 51c in each row. Plungers 571 of these solenoids 57a to 57c
are connected to one end of each of the locking levers 58a to 58c by a pin. These locking levers 58a~
A substantially central portion of 58c is supported by a shaft 581.
Both sides of the shaft 581 are fixed to both sides of the box 54. 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 engage with the corresponding ratchet gears 52a-52c, respectively, to stop the rotating drums in each row and maintain the locked state.

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 a combination of the alignment state and the display state of numerical information displayed on the segment display 50B.

Other examples of the specific gaming state include only the display state of the rotary drum display mechanism 50A, only the display state of the segment display 50B when a plurality of digits are provided, or a specific winning state provided on the game board 1. The case may be based on any case where there is a ball passing through the area.

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, numerical information display drive circuit 67, ball release drive circuit 68 and drive control circuit 7
Contains 0.

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 detects the display state of the rotating drum display mechanism 50A and the segment display 50B.
Based on the combination with the display state of , it is detected that a predetermined specific gaming state has been entered. In addition, the specific gaming state detection circuit 64 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 winning ball number detection circuit 65 is
It is detected 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 given in a specific game state (for example, a state in which a relatively large number of prize balls set as the number of stoppages is given).
The ball ejection drive circuit 68 includes an addition/subtraction counter that counts the number of winning balls that exceeds a certain number and is won by the variable winning ball device 40 in a specific game state, and sends a number of balls corresponding to the counted value of the addition/subtraction counter to the prize ball ejection port. 12
It is something that is released into the world.

FIG. 7 is a detailed circuit diagram of the predetermined number of winning balls detection circuit 65, the ball discharge drive circuit 68, and the drive control circuit 70. The drive control circuit 70 includes an OR gate 71, timers 72 to 74, a driver 75, and a repeating opening/closing drive circuit 76 for a certain period of time. Here, the driver 75 drives 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 repetitive opening/closing drive circuit 76 for a certain period of time is
An example of putting the variable winning ball device 40 into the first state is to put it into a state where it is easy to win continuously for a relatively long fixed period of time (for example, t1 = 30 seconds).

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. When the player is playing a ball hitting game, the ball falls into the safe holes 2a to 2c or the Yakumono 4.
When a prize is won in either a or 4b, the prize ball release mechanism 24 is activated to control the release of a predetermined number of prize balls for each winning ball. That is, the meandering path 21
When the winning balls that are guided by the ball 4 and fall are placed on the ball receiver 232, the cylindrical member 231 rotates. At this time, the hook 235 formed on the lever 236 connected to the cylindrical member 231 is disengaged, the prize balls are prepared to be released, and the flow path switching plate 251 is closed. There is. The winning balls dropped by the winning ball processing device 23 pass through the flow path switching plate 251 and are placed on the tip of the lever 241, and the lever 241 is rotated downward about the fulcrum 242 by its own weight. The rotation of the lever 241 pushes up the vertical lever 243 and releases a predetermined prize ball from the ball storage section 244. At this time, the released prize balls are placed on the ball mounting board 247, and the ball's own weight pushes down and rotates the ball mounting board 247, thereby guiding it to the prize ball discharging port 12. At this time, the lever 237 is pulled up by the rotation of the bearing plate 247, and the cylindrical member 231 is accordingly returned. In this way, a predetermined number of prize balls are mechanically released each time the prize ball processing device 23 sequentially drops one prize ball.

On the other hand, when the ball hits any of the winning areas 3a to 3c, the corresponding detection switch 22a, 2
2b is derived at a high level and is applied to the drive circuit 621 via the OR gate 611 and also to the timer 622. Furthermore, the output of OR gate 611 causes flip-flop 631 included in display drive circuit 63 to be set. Accordingly, the drive circuit 6
21 is activated by energizing the solenoids 57a to 57c to disengage the claw-like portions 582 of the locking levers 58a to 58c from the corresponding latch gears 52a to 52c, and rotationally driving the motor 56. Then, the rotating drums 51a to 51c in each row are rotationally driven to vary the display state of the rotating drums. At the same time, the set output of flip-flop 631 is provided 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, AND gate 632 derives a clock pulse according to the set output of flip-flop 631 and supplies it to ring counter 634. The ring counter 634 cyclically counts the numerical values 0 to 9 that can be displayed on the segment display 50B according to the input of the clock pulse, and sends the counted value to the decoder driver 635 and the specific game state detection circuit 64. It is applied to the included determination circuit 645. Decoder driver 6
35 decodes the count value of the ring counter 634 and displays the segment display 5 based on the count value.
The numbers displayed at 0B are sequentially changed in synchronization with the period of the clock pulse. In this way,
By rotationally driving the rotating drums 51a to 51c and variably displaying the segment display 50B, mechanically variable display and electrically variable display are performed simultaneously.

As described above, the rotating drums 51a to 51c
In a state where the segment display 50B is variably displayed, the player presses the stop command switch 17 so that the combination of display states of the rotating drums 51a to 51c in each row becomes a specific game state. Note that timer 6 starts after variable display starts.
If the stop command switch 17 is not pressed within a certain period of time set by the timer 622, 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. and,
The drive circuit 621 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 resets the flip-flop 631 and is applied to the display state determination circuit 643 as a determination command signal. In response, AND gate 632 stops deriving clock pulses. Therefore, the count value of the ring counter 634 is not incremented, and therefore the count value of the ring counter 634 is not incremented.
Numbers corresponding to the count value counted at 34 are continuously displayed on the 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. Each sensor 6
The light projecting portions and light receiving portions 41 and 642 are provided facing each other on both axially outer sides of all the rows of rotating drums. 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. A portion with a through hole and a portion without a through hole are provided at positions on the circumference and the second circumference. This makes it possible to identify four types of identification information based on the combination of 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'', four types of 2-bit codes ``00'' and ``01'' are generated. ，
By "10" and "11", it is possible to detect the combination of identification information of the rotating drums in each row. The display state determination circuit 643 then determines whether the rotating drum 51
A score is determined based on the combination of identification information displayed in a to 51c, and the score is sent to the drive control circuit 7.
0 and is applied to the determination circuit 645.

If the combination of identification information displayed on the rotating drums 51a to 51c is a combination of a specific game state,
That is, unless the combination is determined to give the maximum value (for example, all symbols are A), the display state determination circuit 643 determines that a value smaller than the maximum value should be given based on the combination at that time. One of the representing determination signals j2 to j4 is derived. Each judgment signal j2 to j4 corresponds to the corresponding timer 7.
2 to 74. Each timer 72, 73, 7
4 are the corresponding judgment signals j2, j3, j
4, a predetermined period of time t2, t
3, a high level signal is derived for only t4. Here, the fixed time set by the timers 72 to 74 is selected such that t2≧t3≧t4,
For example, t2=10 seconds, t3=6 seconds, and t4=4 seconds are selected. Note that the determination circuit 645 does not determine the display state of the segment display 50B if the determination signal is other than j1 (ie, j2 to j4).

For example, assuming that the display state determination circuit 643 derives the determination signal j2, the timer 72 derives a high level signal for a certain period of time t2. This high level signal is applied to one input terminal of AND gate 681 via OR gate 71. A high level signal is applied to the other input terminal of the AND gate 681. This is because the OR gate 682 derives a low level signal since the predetermined number of winning balls detection circuit 65 is not operating. In response, AND gate 681 provides a high level signal to driver 75. That is, the AND gate 681 receives the output signal of the OR gate 71 (that is, there is a high level output of the timer 763).
And based on the output signal of the OR gate 682 (that is, the number of winning balls does not exceed a certain number),
The driver 75 is driven. Therefore, the driver 75 continuously energizes the solenoid 451 for a certain period of time t2. Therefore, the variable winning ball device 40
The opening/closing plate 41 is opened for a predetermined period of time t2 to allow the hit ball to win. At this time, when a ball enters the winning area 43b or 43c, the prize ball releasing mechanism 24 operates in the same manner as described above to release a predetermined number of prize balls depending on the winning ball. However, even if the ball enters the winning area 43a, the variable winning ball device 40
1 without extended control of the opening operation of the
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 uses the determination signal j1
is derived and applied to the determination circuit 645 and as a set input to the flip-flop 761. Flip-flop 761 is set accordingly. Further, the determination circuit 645 determines whether the count 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 determination signal j1. Determine whether or not. At this time, the determination circuit 645
Even if the combination of display states of the rotating drums 51a to 51c is the state that gives the maximum value, the maximum value giving command signal j0 (high level) is not derived unless the segment display 50B is displaying 7. . In this case, the set output of flip-flop 761 set by determination signal j1 is applied to timer 763 via OR gate 762. In response, the timer 63 starts counting a certain period of time t1, and during that period a high level signal is derived and applied to the collector of the transistor 764. At this time, the mismatch output (low level) of the comparison circuit 653 is inverted to high level by an inverter 655 and applied to the base of the transistor 764.
Therefore, the transistor 764 is connected to the comparator circuit 653.
is conductive during the period in which the output of the timer 763 is deriving a non-coincidence output, and the output of the timer 763 is applied to one input terminal of the AND gate 681 via the OR gate 71. At this time,
A high level signal is applied to the other input terminal of the AND gate 681. Therefore, AND gate 681 provides a high level signal to driver 75. In response, the driver 75 energizes the solenoid 451 to open the opening/closing plate 41. In this case, AND gates 651 and 769 remain disabled since flip-flop 766 is not set. Therefore, the predetermined number of winning balls detecting circuit 65 does not count the winning balls in 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 game state is reached, that is, the combination of the display states of the rotating drums 51a to 51c becomes a predetermined state that can give the maximum value (all display states of symbols A), and the segment display 50B
When the display state 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 645. At this time, the AND gate 646 derives a high level determination signal j0 because the low level of the output of the predetermined value provision state detection circuit 66 is inverted to a high level. This decision signal j0 causes flip-flop 766 to be set.
Therefore, when a specific game state is entered, the aforementioned rotating drums 51a to 51c are activated according to the determination signal j1.
After performing the operation when only the display state becomes the maximum value giving state, a repeated value giving action based on the specific gaming state is performed. 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, the AND gate 651 is connected to the flip-flop 7.
66 set output. Therefore, when a ball is hit into any of the winning areas 43a to 43c, it is detected by the detection switch 44b. The detection output of the detection switch 44b is applied to a counter 652 via an AND gate 651. The counter 652 counts the number of winning balls in the winning areas 43a to 43c after the 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 given the number of winning balls (for example, 10) that can be won into the variable winning ball device 40 in the specific gaming state set by the setting section 654 as a reference input. Comparison circuit 653 derives a low level signal from terminal A when the count value of counter 652 is smaller than the reference input. This low level signal is inverted to high level by the inverter 655 and given as the base input of the transistor 764, so that
Transistor 764 provides a high level signal of the output of timer 763 to OR gate 71 . Further, the count value of the counter 652 is
7 is displayed on the numerical information display 6. 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 a predetermined number of winning balls are received before the timer 763 times up,
Comparison circuit 653 derives a high level signal from terminal B. This high level signal is the OR gate 682
given to. The output of OR gate 682 is inverted to a low level signal disabling AND gate 681. In response, driver 75 deenergizes solenoid 451. In this way, when the specific gaming state is entered, if the number of winning balls in the winning area 43 reaches a predetermined number before the fixed time t1 set by the timer 763 has elapsed, the solenoid 451 is forcibly activated. is deenergized, and 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 applied to a monostable multi 768. Monostable multi 768 derives a high level for a certain period of time,
The output is applied to AND gates 769 and 76a, and flip-flop 761 is reset.

Next, in a specific game state that is a feature of this invention, when more than a certain number of balls enter the variable winning ball device 40, that is, when the count value of the counter 652 suddenly exceeds a certain number (for example, 10) Or, if winning balls exceeding a certain number occur during closing of the opening/closing plate 41 after the count value of the counter 652 reaches a certain number, the following operation is performed. Comparison circuit 653 derives a high level signal from terminal C and applies it to one input terminal of OR gate 682 and AND gate 683. The output of OR gate 682 is applied to one input terminal of AND gate 684.
On the other hand, the AND gate 683 activates the addition/subtraction counter 69 because the high level signal that detects the winning ball is given from the AND gate 651 to the other input terminal. That is, the addition/subtraction counter 69 adds the number of winning balls exceeding a certain number based on the high level signal of the AND gate 683. At this time, the zero detection circuit 685 derives a low level signal indicating that the count value of the addition/subtraction counter 69 is not zero. This low level signal is inverted by an inverter 686 and output to an AND gate 684.
given to. For this reason, AND gate 684
is based on the fact that there are more than a certain number of winning balls and the count value of the addition/subtraction counter 69 is not zero.
The driver 687 is driven. Driver 687 energizes solenoid 253. In response, the solenoid 253 rotates the flow path switching plate 251 toward the released ball detection switch 26 side. For this reason, the ball receiving part 2
Winning balls exceeding a certain number listed on 32 will be placed in the second prize.
As shown in FIG. D, the cylindrical member 231 is rotated, passes through the meandering path 214, falls into the release path 27, and is returned to the prize ball release port 12 through the release path 28. At this time, when the winning ball falls into the release path 27, the released ball detection switch 26 detects the winning ball, gives a subtraction command signal to the addition/subtraction counter 69, and energizes the solenoid 257. Accordingly, the addition/subtraction counter 69 subtracts the number of winning balls returned based on the output signal of the released ball detection switch 26. Further, the solenoid 257 presses the protruding piece 233 and rotates the cylindrical member 231 so that the winning ball is placed on the ball receiving portion 232.

Then, when the count value of the addition/subtraction counter 69 becomes zero, the zero detection circuit 685 derives a high level signal. This high level signal is sent to the inverter 6
is inverted at 86, disabling AND gate 684. In response, driver 687
Deactivate 53. As a result, the flow path switching plate 25
1 returns to its original state by the elastic force of the spring 254, in other words, to become a part of the meandering path 214.

In addition, if there are a plurality of winning balls exceeding a certain number, the following operation will be performed. That is, the released ball detection switch 26 energizes the solenoid 257 and rotates the cylindrical member 231 every time a winning ball is detected.
Then, in response to the released ball detection switch 26 detecting a plurality of winning balls exceeding a certain number, the count value of the addition/subtraction counter 69 becomes zero. At the same time, zero detection circuit 685 drives driver 687 to deenergize solenoid 253. As a result, the flow path switching plate 251 returns to its original position. Also,
The cylinder member 231 rotates. In this way, in a specific game state, if more than a certain number of winning balls enter the variable winning ball device 40, more than the certain number of winning balls are released from the prize ball discharging port 12. The predetermined number of winning balls detection circuit 65 and ball release drive circuit 68
In addition, the driver 75 constitutes invalidation processing means for invalidating the exceeded number of winning balls when the number of winning balls won in the first state of the variable winning ball device exceeds the certain number. By the function of this invalidation processing means, the excess balls awarded in excess of the predetermined number (10) are invalidated and the release of prize balls based on the excess balls is prevented. The feature of the present invention is to prevent the payout of prize balls due to excess balls exceeding the predetermined number (10 balls), thereby avoiding losses to the gaming hall. Therefore, the types of pachinko gaming machines are not limited to those equipped with the variable display device 50 described in this embodiment. If a pachinko ball that has won in the variable winning ball device enters a specific winning area during the opening and closing operation a number of times (for example, once or twice), the variable winning ball device is opened and closed a relatively large number of times in succession. 1
It may be a type of pachinko game machine that is controlled to the state of.

In addition, in the above-mentioned embodiment, the prize ball release mechanism 24
Although a case has been described in which the prize balls are mechanically released, the present invention is not limited to this, and the prize ball release mechanism 24 may be configured to electrically release the prize balls. In this case, a detection switch that detects the rotational state of the cylindrical member 231 and an output of the AND gate 683 are used.
A ball discharging mechanism that releases balls to the prize ball discharging port 12, the number of times prize balls corresponding to a certain number of winning balls are released from the prize ball discharging mechanism 24 to the prize ball discharging port 12, and the number of times the ball discharging mechanism releases the balls. It is sufficient to provide a counter that subtracts and adds each output signal of the detection switch.

Next, a case where the variable winning ball device 40 is repeatedly driven to open will be described. When a ball enters the winning area 43a during the period in which the variable winning ball device 40 is being driven to open after the specific game state, the detection switch 44a outputs an output to set the flip-flop 6b. Therefore, the AND gate 769 determines that there is a set output of the flip-flop 66 (that is, that the game is in a specific gaming state),
Based on the presence of the set output of the flip-flop 76b (that is, the detection of a condition that allows the variable winning ball device 40 to be repeatedly opened) and the presence of the output of the monostable multi 68 (that is, the opening of the variable winning ball device 40). Then, a high level signal is derived and sent to the timer 7 via the OR gate 762.
Give to 63. In response, timer 763 again starts counting operation for a certain period of time t1, and during that period derives a high level signal and provides it to driver 75 via transistor 764, OR gate 71 and AND gate 681. As a result, after entering the specific gaming state, the variable winning ball device 40 is repeatedly driven to open as long as the repeating condition is detected.
It should be noted that after a certain period of time has elapsed from the output of the monostable multi-channel 768, the delay circuit 76c outputs the flip-flop 76b.
to reset. In this case, the reset output of flip-flop 76b is applied to AND gate 76a, but since the output of monostable multi 768 is no longer applied, AND gate 76a does not derive a high level signal.

After that, in the same way, after the specific game state, the winning area 4
As long as there are winning balls in 3a, the variable winning ball device 40 can be repeatedly opened and driven until a predetermined number of winning balls allowed during a certain time t1 or one opening period are generated.

In addition, when the variable winning ball device 40 is repeatedly driven to open, the ball is in the winning area 43a.
If you don't win any prizes, flip-flop 76
b remains reset. In this case, the AND gate 76a derives a high level signal according to the output of the monostable multi 768, and the OR gate 76a derives a high level signal.
6d to reset flip-flop 766. As a result, the repeated opening and driving operation of the variable winning ball device 40 is thereafter terminated. Even in this case, when more than a certain number of winning balls enter the variable winning ball device 40, the winning balls are released into the prize ball discharge port 12 in the same manner as described above.

In addition, after the specific game state, each time the variable winning ball device is repeatedly driven to open, the ball moves to the winning area 43.
If you repeatedly win a, the variable winning ball device 40
The repeated opening operation continues. However, when the predetermined value award state detection circuit 66 detects that a relatively large number of prize balls have been released, the detection output resets the flip-flop 766 via the OR gate 76d. This also ends the repeated opening/closing driving operation of the variable winning ball device 40.

In addition, in the above-mentioned embodiment, as a repeat condition detection means, the case where one or more winning balls entered the winning area 43a during the opening period of the variable winning ball device 40 after a specific gaming state was explained, but other A repeating condition may be detected. For example, when 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 balls), and the flip-flop 76b may be set by the output of the comparison circuit.

Incidentally, 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, but the technical idea of the present invention is that a program is implemented using a microprocessor. This can also be done by treatment. In that case,
Those skilled in the art will 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.

As described above, according to the present invention, in a pachinko gaming machine that can generate many winning balls with a relatively high probability based on a specific gaming state,
If more than a certain number of winning balls enter the variable winning ball device when the player is in an advantageous situation, it is possible to prevent the release of prize balls corresponding to the winning balls that exceed a certain number and reduce losses to the gaming hall. It has the unique effect of being able to reduce the number of players and meeting the permission standards for gaming machines.
