Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a pachinko game machine, and in detail,
This invention relates to a pachinko game machine in which a variable prize winning ball device is disposed on a game board and can be changed freely between a first state that is advantageous to the player and a second state that is disadvantageous to the player.

[Prior Art] In general, pachinko gaming machines that use pachinko balls to play games are widely used and are popular among players as one of the convenient cash registers. As is well known, pachinko machines have multiple safe holes and winning ball devices (Yakumono, commonly known as chulips) on their game boards.
are arranged, and when a player hits a pachinko ball, if the ball hits a safe hole or a yakumono with a certain probability, a certain number of prize balls are released. For the purpose of providing services to players, conventional pachinko machines open a predetermined number of prizes when a ball enters a certain safe hole or winning area.
He was cultivating a certain yakumono business for a short time. 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 short period of time based on winning balls in a specific winning area, so players can If you want to win a large amount of prize balls by playing until the machine stops,
It required excellent gaming skills and the patience to play continuously for long periods of time. For this reason, many experienced pachinko players, known as pachinko players, were able to win a large amount of prize balls from a single pachinko ball game 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.

[Problems to be solved by the invention] Therefore, the applicant of the present application previously filed Japanese Patent Application No. 54-145643.
No. and Japanese Patent Application No. 145644/1987, a variable winning ball device such as a Yakumono is put in a state where it is easy to win for a relatively long time based on a specific gaming state,
We proposed a pachinko machine that allows you to win a large number of prize balls at once. However, the previously proposed system simply makes the variable winning ball device easier to win for a relatively long period of time, so the variable winning ball device can be changed depending on the adjustment state of the nail installed near the variable winning ball device. During one opening period of the winning ball device, there were some machines that produced more than a dozen winning balls, and others that produced almost no winning balls, and the winning probability varied more than expected depending on the machine. 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 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 a large number of winning balls occur at once, the winning balls will be discontinued 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 in which the number of balls is limited to limit the variation between pachinko machines within a certain range, and the variation in the number of prize balls awarded when a specific gaming state is reached is smaller than before. The purpose is to provide a machine.

[Means for Solving the Problems] A pachinko game machine according to the present invention is a pachinko game machine that includes a game board in which a winning area is formed, and that 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 in which the player becomes disadvantageous and a second state that is disadvantageous for the player, and a pachinko game state that allows the variable winning ball device to change to the first state for a certain period of time. a specific gaming state detection means for detecting that a predetermined state has been reached; when the variable winning ball device is in a first state, the number of winning balls entered into the variable winning ball device is within the fixed number allowed within the certain period; a predetermined number of winning balls detecting means for detecting that the number of winning balls has reached a predetermined number, and driving the variable winning ball device to a first state in accordance with the output of the specific game state detecting means to detect the predetermined number of winning balls within the certain period of time. The variable winning ball device is activated by the second variable winning ball device in response to an output from the detection means or when there is no output from the predetermined number of winning balls detecting means and a certain period of time has elapsed.
The present invention is characterized in that it includes a drive control means for driving the vehicle to the state shown in FIG.

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

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 closing portion 32 is selected as 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 the ball receiving plate 341 are guided to the back side through a hole that becomes the winning area 3a. Passage areas 342, 34 for passing balls are provided in a laterally extending portion of the frame member 34.
3 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

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 thereof and detected by a detection switch 44a, which is an example of specific game state detection means provided below. Winning areas 43a to 43c
The winning balls are guided downward through 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.

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, which has a pair of ball receiving pieces opened on the left and right sides to make it easier for the player to win a ball, in a state advantageous to the player. 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. Further, as yet another example of the variable prize winning ball device, an opening/closing plate that can be opened to the front of the game board 1 is provided, and a ball entrance for receiving one ball is formed at the top of the opening/closing plate. The opening/closing plate may be in a closed state, and the opening/closing plate may be opened based on a certain game state.

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. On the outer periphery of each row of rotating drums 51a to 51c, identification information such as a picture pattern, a symbol, or a number (for example, a picture pattern such as a bell, black, or a yacht, or a symbol such as a number or an alphabet) is drawn. 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 lock 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 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 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 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. The specific gaming state detection circuit 65 preferably includes a mechanism that detects not only the specific gaming state but also other gaming states and a condition that allows the variable 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 prize balls are given).

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 includes an OR gate 71 and timers 72 to 7.
4, includes a driver 75 and a fixed time repetitive opening/closing drive circuit 760. Here, the driver 75 activates the solenoid 451 during the output period of the OR gate 71 to move the variable winning ball device 40 to the first position.
This is to drive it to the state of. The constant time repeated opening/closing drive circuit 760 is one example of putting the variable winning ball device 40 in the first state, and makes it easy to win continuously for a relatively long fixed 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. The player puts the ball borrowed from the ball lending machine into the ball waiting gutter 13, adjusts the strength of the ball by rotating the ball hitting handle 14, and then turns the ball hitting switch 14.
Press s. Electric power is supplied to the motor 241 in response to the depression of the ball hitting switch 14s. depending on,
The motor 241 is rotationally driven and the ball hitting hammer 243 is rotated intermittently to sequentially drive balls into the game board 1 one by one. When the player is playing a ball hitting game in this way, if the ball lands in either the safe holes 2a to 2c or the Yakumono 4a, 4b,
The prize ball release mechanism operates to control the release of a predetermined number of prize balls for each winning ball. On the other hand, when the ball hits any of the winning areas 3a to 3c, the corresponding detection switches 22a and 22b output a high level, and the driving rotation 62 is output via the OR gate 611.
1 and also to the timer 622. Further, 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 close the locking levers 58a-5.
Ratchet gear 5 corresponding to claw-like portion 582 of 8c
By releasing the engagement state with 2a to 52c and rotating the motor 56, 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, the set output of flip-flop 631 is provided as one input of AND gate 632. AND gate 632 is always supplied with the output clock pulse of clock oscillator 633 as a local 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 635 decodes the count value of ring counter 634, and based on the count value, sequentially changes the numerical value displayed on segment display 50B in synchronization with the cycle of the clock pulse. In this way, the rotating drums 51a to 5
1c is rotationally driven and the segment display 50B
By variably displaying , mechanically variable display and electrically variable display are performed simultaneously.

In the state where the rotating drums 51a to 51c and the segment display 50B are each displaying a variable display as described above, the player can set the combination of display states of the different rotating drums 51a to 51c to a specific game state. Press the stop command switch 17. Note that after starting the variable display, the timer 62
If the stop command switch 17 is not pressed within the fixed time set in step 2, a stop command is issued by the output of the timer 622. Accordingly, the drive circuit 6
21 deenergizes the solenoids 57a to 57c in a predetermined order (or in an irregular order) to sequentially stop the rotating drums 51a to 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 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.
It is counted as 34. A number corresponding to the count value is displayed on a 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. 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 a 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. ,
With "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 A symbols), the display state determination circuit 643 should give a value smaller than the maximum value based on the combination at that time. One of the determination signals j2 to j4 representing the following is derived. Each determination signal j2-j4 is given to a corresponding timer 72-74. Each timer 72, 7
3 and 74 are the corresponding determination signals j2 and j, respectively.
3, a predetermined period of time t according to the input of j4.
2, t3, and t4 to derive high level signals. 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, t4=
Selected in 4 seconds. Note that the determination circuit 645 determines that if 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.

For example, assuming that the display state determination circuit 643 derives the determination signal j2, the timer 7
2 derives a high level signal for a certain period of time t2. This high level signal is applied to the driver 75 via the OR gate 71. In response, 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. Kotoki, ball winning area 4
When a prize is won in 3b or 43c, the prize ball discharging mechanism releases a predetermined number of prize balls according to the winning ball. However, even if the ball enters the winning area 43a,
The opening operation of the variable winning ball device 40 is not extended and controlled, 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 uses the determination signal j1
is derived and applied to the determination circuit 645 and as a set input to the flip-flop 761. Accordingly, flip-flop 761 is set. 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 64
5 derives the maximum value giving command signal j0 (high level) if the segment display 50B does not display 7 even if the combination of display states of the rotating drums 51a to 51c gives the maximum value. do not. 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, 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 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
53 is conductive during the period when the discrepancy output is being derived,
The output of the timer 763 is given to the driver 75 via the 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 76
Since 6 is not set, AND gate 65
1 and 767 remain disabled. 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 gaming state is reached, which is a feature of the present invention, 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 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, the AND gate 646 detects the predetermined value provision state detection circuit 66
Since the low level of the output of is inverted to the high level, a high level judgment signal j0 is derived. This decision signal j0 causes flip-flop 766 to be set. Therefore, when the specific gaming state is reached, only the display states of the rotating drums 51a to 51c described above are operated in accordance with the determination signal j1 in the case where the maximum value giving state is reached, and then the operation based on the specific gaming state is performed. Repeated value adding operations are performed. That is, the mater 763 derives a high level for a certain period of time t1 from when the determination signal j1 is applied, drives the driver 75, and controls the opening/closing plate 41.
to be established. At this time, AND gate 651 is enabled by the set output of flip-flop 766. For this reason, the ball hit is in the winning area 4.
If you win any one of 3a to 43c, it will be detected by the detection switch 44b. Detection switch 4
The detection output of 4b is given to a counter 652 via an AND gate 651. The counter 652 counts winning areas 43a to 43c after a specific gaming state.
The number of winning balls is counted and the counted value is given to a comparison circuit 653 and a numerical information display drive circuit 67. The comparison circuit 653 receives the number of winning balls (for example, 10) that can be won into the variable winning ball device 40 in the specific game state set by the setting section 654 as a reference input. 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. 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 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. 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 the specific gaming state is entered, the fixed time t set by the timer 763
If the number of winning balls in the winning area reaches a predetermined number before 1 elapses, the solenoid 451 is forcibly 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 a monostable multi-7
68. The monostable multi 768 derives a high level for a certain period of time, provides its output to AND gates 769 and 76a, and resets the flip-flop 761.

By the way, after the specific game state, the variable winning ball device 4
When a ball enters the winning area 43a during the period in which the 0 is being driven open, the detection switch 44a outputs a detection output to set the flip-flop 76b. For this reason, and gate 769
This means that there is a set output from the flip-flop 766 (that is, it is in a specific gaming state), that there is a set output from the flip-flop 76b (that is, that a condition that allows the variable winning ball device 40 to be repeatedly opened is detected), and that the monostable multiplayer 768
(i.e., the variable winning ball device 40
Based on the invention of
Give to 3. In response, timer 763 again starts counting 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 and OR gate 71. As a result, after entering the specific gaming state, the variable winning ball device 40 is repeatedly opened and driven as long as the detection switch 44a detects the repeating condition. Incidentally, after a certain time delay from the output of the monostable multi 768, the delay circuit 76c resets the flip-flop 6b. In this case, flip-flop 76
The reset output of B is applied to the AND gate 76a, but since the output of the monostable multi 768 has not been applied as the other input of the AND gate 76a, the 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. As a result, in the pachinko gaming machine 10 in which the number of prize balls to be paid out after entering a specific gaming state is limited, the variable winning ball device 4
There is an advantage that the number of winning balls during one opening period of 0 can be limited to a predetermined number or less, and the number of repeated openings can be increased. 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, if no ball enters the winning area 43a, the flip-flop 76b
remains reset. In this case, the AND gate 7
6a derives a high level signal, and OR gate 7
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.

In addition, after the specific game state, each time the variable winning ball device is repeatedly driven to open, the ball moves into the winning area 43a.
When the player repeatedly wins, the repeated opening operation of the variable winning ball device 40 continues. However, when the predetermined value award 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 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 repetition condition may also be detected. for example,
If the number of winning balls in any of the winning areas 43a to 43c is greater than or equal to the number of balls (for example, 3 balls) that is smaller than the number of balls (for example, 10 balls) detected by the predetermined winning ball number detection circuit 65, the repeat condition is met. It may be configured to detect. In that case, counter 6
A comparator circuit for detecting that 52 has counted a relatively small number of winning balls (3) may be separately provided, and the flip-flop 76b may be set by the output of the comparator circuit.

Further, in the above-mentioned embodiment, a case has been described in which the repetitive condition detection 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, the time during which the variable winning ball device 40 is opened and driven in a specific gaming state is significantly lengthened, and when a predetermined number of winning balls (for example, 50) is detected within that time, or when a relatively long fixed period of time has elapsed. The variable winning ball device 40 may be closed at any time.

Further, as another embodiment of the drive circuit 70, an AND gate is provided between the OR gate 71 and the driver 75, and the variable The winning ball device 40 may be driven to open and close within a relatively long fixed period.

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 perform program processing using a microprocessor. It can also be done by. 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 gaming machine that can generate many winning balls with a relatively high probability based on a specific gaming state,
The variable winning ball device can be driven to a state where it is easy to win for a certain period of time, or it can be driven to a state where it is easy to win until the number of winning balls reaches a certain number. Also, unique effects such as being able to limit the variation in the number of winning balls for each player within a certain range are produced. 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 winning is easy, it is possible to equalize the service to many players without giving a large amount of prize balls only to a specific player. be.
