Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pachinko gaming machine, and more specifically, 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 winning ball device that can be changed freely is arranged on a game board.

[Prior Art] For this type of pachinko game machine, some of the commonly known ones include, for example,
- There is a method described in Publication No. 78975, in which when a predetermined specific game state is entered, the variable winning ball device is set to the first state, and a predetermined number of balls hit within a predetermined time win or a predetermined number of balls. The variable winning ball device was driven and controlled to the second state based on the predetermined time elapsed without winning a prize.

However, in this type of conventional pachinko gaming machine, the first state of the variable winning ball device that occurs based on the specific gaming state becomes 1 when the termination condition determined by the above-mentioned predetermined time and the predetermined number of winning balls is met. Since the game ends after just one turn, it has the disadvantage that it is not sustainable and cannot provide a sufficient sense of satisfaction to the player.

[Problems to be Solved by the Invention] Therefore, the variable winning ball device is driven to the first state again based on the establishment of a predetermined repetition continuation condition while the variable winning ball device is in the first state. It is also conceivable to configure the system to perform repeated and continuous control.

However, since this repeat continuation control only requires that the repeat continuation condition is satisfied when the variable winning ball device is in the first state, the repeating control is performed after the variable winning ball device switches to the second state. If the continuation condition is satisfied, the repeat continuation control is not performed, and the second continuation control of the variable winning ball device
There is a risk that troubles between the gaming hall and the players will occur frequently after the continuation conditions are met after the period of change to the state of Even if control is adopted, a new technical problem arises in that the above-mentioned troubles end up causing dissatisfaction to the players.

In view of the above circumstances, the present invention provides a pachinko game that provides a sufficient sense of satisfaction to the player through repeated continuation control, while also preventing player dissatisfaction due to troubles that occur after the repeated continuation condition is satisfied. The purpose is to provide a machine.

[Means for Solving the Problems] The pachinko game machine according to the present invention is characterized in that the pachinko game machine detects when the variable winning ball device is in a predetermined state such that it can change the variable winning ball device to the first state for a certain period of time. A specific game state detecting means for detecting, when the variable winning ball device is in the first state, a predetermined device for determining that the number of winning balls in the variable winning ball device has reached a certain number allowed within the certain period of time; winning ball number determining means; repeating condition detecting means for detecting a predetermined condition such that the variable winning ball device can be repeatedly brought into the first state after output from the specific gaming state detecting means; and detecting the specific gaming state. The variable winning ball device is driven to a first state in accordance with the output of the means, and there is an output of the predetermined number of winning balls determining means within the certain period of time, or there is no output of the predetermined number of winning balls determining means and a certain period of time has elapsed. Depending on the situation, the variable winning ball device can be set to a second
drive control means for driving the variable winning ball device to the first state again according to the output of the repetition condition detection means, and driving the variable winning ball device to the first state even after the variable winning ball device is in the first state. The present invention is characterized in that it includes a detectable state maintaining means for maintaining a detectable state by the repetition condition detecting means.

[Operation] If the repeat continuation condition is satisfied when the variable winning ball device is in the first state, the variable winning ball device in the first state is once brought to the second state and then driven to the first state again. This repeated and continuous control is performed.
In addition, due to the function of the detectable state maintaining means, even after the variable winning ball device switches to the second state, the output of the repeating continuation condition detecting means is effectively used for the repeating continuation control for a predetermined period, so The repeat continuation condition established after the ball device is switched to the second state is also effectively used for repeat continuation control and controlled to be advantageous 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 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
2 (i.e. the part 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, 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 that purpose, the winning ball in the winning area 43a is guided to the back side of the winning ball, and a detection switch 4, which is an example of repeat condition detection means provided below,
Detected at 4a. 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.

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. 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. 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 rotating 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.

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, includes 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. Note that 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 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).

FIG. 7 is a detailed circuit diagram of the drive control circuit 70 and the predetermined winning ball detection circuit 65 which is an example of the predetermined winning ball number determining means. This drive control circuit 70 is
OR gate 71, timers 72 to 74, driver 7
5 and a repetitive opening/closing drive circuit 760 for a certain period of time. Here, the driver 75 is the or gate 71
By energizing the solenoid 451 during the output period, the variable winning ball device 40 is driven to the first state. The opening/closing drive circuit 76 repeatedly opens and closes for a certain period of time as an example of putting the variable winning ball device 40 into the first state for a relatively long period of time (for example, t1).
= 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 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 signal to the drive circuit 62 via the OR gate 611.
1 and also to the timer 622. Furthermore, the output of the OR gate 611 is
The flip-flop 631 included in 3 is set. Accordingly, the drive circuit 621 drives the solenoid 5
7a to 57c are biased to lock the locking levers 58a to 58.
The latch gear 5 corresponding to the claw-like portion 582 of c.
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. 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 635 decodes the count value of ring counter 634, and based on the count value, sequentially changes the number 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.

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 the variable display is disclosed.
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. ,
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 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 times set by the timers 72 to 74 are selected so that t2≧t3≧t4, for example, t2=10 seconds, t3=6 seconds, and t4=4 seconds. 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 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. At this time, when a ball enters the winning area 43b or 43c, the prize ball release mechanism releases a predetermined number of prize balls according to 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 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, the timer 763 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 comparator circuit 653, which is an example of a constant number determining means, is inverted to high level by an inverter 655 and applied to the base of the transistor 764. Therefore, transistor 764 is rendered conductive during the period in which comparator circuit 653 derives a mismatch 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, AND gates 651 and 767 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, 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, 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 a specific gaming state is entered, 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, based on the specific gaming state, Repeated value adding operations are performed. That is, the timer 763 outputs the determination signal j1
A high level is derived for a certain period of time t1 from the given time, and the driver 75 is driven to open the opening/closing plate 41. At this time, and gate 65
1 is enabled by the set output of flip-flop 766. 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. counter 652
is the winning area 43a to 4 after the specific gaming state.
The number of winning balls in 3c 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 compares the variable winning ball device 40 in the specific gaming state set by the setting section 654.
The number of winning balls (for example, 10) that can be won is given as a standard 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 output 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
When 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, where it is differentiated into falling. 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 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 for 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 76
8 output (i.e. variable winning ball device 4
0), a high level signal is derived and sent to the timer 76 via the OR gate 762.
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. That is, the detection switch 44a constitutes a repeating condition detecting means for detecting a predetermined condition so that the variable winning ball device can be brought into the first state repeatedly. It should be noted that after a certain time delay from the output of the monostable multiplier 768, the delay circuit 76c resets the flip-flop 76b. Thereby, even after the variable winning ball device enters the second state, the detectable state by the repeating condition detecting means is maintained for the certain period of time, and the detectable state maintaining means is constituted by the delay circuit 76c. There is. The fixed delay time by the delay circuit 76c is, for example, a switching period from when the variable winning ball device switches to the second state until it returns to the first state, or a half period of the switching period. In short, any period may be sufficient as long as the winning ball can reach the detection switch 44a just before the variable winning ball device enters the second state. When said flip-flop is reset, flip-flop 7
The reset output of 6b is applied to AND gate 76a, but since the output of monostable multi 768 has not been applied as the other input of AND gate 76a, 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 where 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 set to a predetermined number. There is an advantage that you can increase the number of times you can repeat the opening by limiting it to the following.

The predetermined number of winning balls detecting circuit 65 and the drive control circuit 70 drive the variable winning ball device to the first state according to the output of the specific gaming state detection means, and detecting the predetermined number of winning balls within the certain period of time. The variable winning ball device is driven to the second state in response to an output from the determining means or when there is no output from the predetermined number of winning balls determining means and a certain period of time has elapsed, and the variable winning ball device is driven in response to the output from the repeating condition detecting means. A drive control means is configured to drive the motor to the first state again.

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.

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 fixed number of prize balls have been paid out, 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 comparator circuit for detecting that the counter 652 has counted a relatively small number of winning balls (3) may be provided separately, and the flip-flop 76b may be set by the output of the comparator circuit.

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.

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 to program a program 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, if a predetermined repetition condition is satisfied during the period of the first state of the variable winning ball device, the first state of the variable winning ball device is repeatedly continued. , the player can enjoy a thrilling sensation for a long time, and can give the player a sufficient sense of satisfaction.

Moreover, due to the function of the detectable state maintaining means,
Even if the repeat continuation condition is satisfied the moment the variable winning ball device enters the second state, the repeat continuation control is performed to give the player an advantage, so the repeat continuation condition is satisfied. It has now become possible to provide a pachinko game machine in which troubles related to the timing can be avoided and players will not feel dissatisfied.
