Description

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

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

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

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

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

On the other hand, if the number of winning balls during one opening period of the variable winning ball device is limited in order to meet the above request, if a large number of winning balls occur in a short period of time, the variable winning ball device will close in a short time. Therefore, players have a desire to know the number of winning balls during the opening period and plan their gaming strategy based on that information.

Therefore, the main purpose of this invention is to make the variable winning ball device easy to win based on a specific gaming state, and when the number of winning balls during that period reaches a certain allowed number or reaches a certain number. When a certain period of time has elapsed without any winnings, the variable winning ball device changes to a state where it is difficult to win a winning ball, and by displaying the number of winning balls until reaching a certain number allowed, the player is informed of the progress of the game. The purpose is to notify the status.

[Means for Solving the Problems] The present invention provides a pachinko game machine that includes a variable winning ball device and a drive control means for controlling the winning state of the variable winning ball device. This pachinko game machine is provided with a counting means for detecting and counting, and a numerical information display means for displaying the counted value of the counting means.

[Function] In response to entering the specific game state, the drive control means,
To put a variable prize winning ball device into a first state advantageous to a player for a certain period of time. In this state, the number of winning balls in the variable winning ball device is detected and counted by the counting means, and the counted value is displayed on the numerical information display means.

Further, when the count value of the counting means reaches a certain number, for example 10, a detection output is derived from the certain number detection means, and according to the output, the drive control means controls the variable winning ball device to be disadvantageous to the player. Put it in the second state. Furthermore, at this time,
For a certain period of time, for example, 30
When it is detected that the second has elapsed, the drive control means puts the variable winning ball device into the second state accordingly. In this way, the drive control means drives and controls the variable winning ball device according to the output of the fixed number detection means or the detection output of the elapse of a certain period of time, whichever comes first.

FIG. 5 is an illustrative diagram showing details of the rotating drum display mechanism 50A.

Next, the configuration of the variable winning ball/variable display device M30 will be explained in detail with reference to FIGS. 3 to 5.

The variable winning ball/variable display device 30 has a configuration in which the variable winning ball device 40 and the variable display device 50 are integrally attached to a mounting plate 31. Specifically, the mounting plate 31 has an opening 32 formed therein. The opening 32 is a horizontally long rectangular hole so as to become a winning area when the opening/closing plate 41 of the variable winning ball device 40 is opened. The mounting plate 31 has displays *33a, 3 for displaying identification information drawn on the rotating drum included in the rotating drum display mechanism 50A.
3b, 330 are formed. Furthermore, the mounting plate 31
A frame member 34 is attached to the top of the frame member 34 . A segment display 50B is attached to the frame member 34, and an inverted V-shaped ball receiving plate 341 is attached to 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 which becomes the winning area Ii 3a. moreover,
Passage areas 342 and 343 for allowing balls to pass are formed in the laterally extending portion of the frame member 34, and
In order to change the fall of the balls that have passed through the passage areas 342 and 343, an appropriate number of obstacle nails 35 are installed in a horizontal row at approximately the center of the mounting plate 31 and above the opening 32. ing. A guide member 36 is installed between the obstruction nail 35 and the opening 32. The guide member 36 has guide plates extending in the vertical direction at a plurality of locations in the lateral direction, and functions to guide the ball in the vertical direction and cause it to fall.

The variable prize winning ball device 40 has the first advantageous effect for the player.
In the second state, the opening/closing plate 41 is opened forward and balls can be easily accepted, and in the second state, which is disadvantageous for the player, the opening/closing plate 41 is closed and balls cannot be accepted.

The structure of such a variable winning ball device 140 will be explained in more detail. The variable prize winning ball device 40 includes an opening/closing plate 41 rotatably attached to the front surface of the frame member 42 (ie, the portion related to the entrance section 32). On both edges of the opening/closing plate 41, there are triangular sides protruding from the back side! 411.412 are provided. The side walls 411, 412 are connected to the frame member 42 by the shaft 413.
It is rotatably attached to the side of the Paths 421 and 422 are formed below the frame member 42. The back side of the frame member 42 is covered with a cover 423. Opening/closing plate 41
The opening 32 in the open state becomes a winning area 43 where balls can easily be won.

The winning area 43 includes a plurality of winning areas 43a to 43 in the horizontal direction.
It is divided into 0. The winning area 43a is an area in which conditions are set such that the opening/closing plate 41 can be opened again by a winning ball during the opening of the opening/closing plate 41 in a specific game state, and the variable winning ball device 40 can be put into a state where it is easy to win a prize. A detection switch 44a is provided for that purpose. The detection switch 44a is for detecting a ball that enters the winning area 43a, is guided to the back side, and falls downward.

Also, the winning balls in the winning areas 43a to 430 are guided downward via paths 421 and 422, respectively. Route 4
A detection switch 44b for detecting a winning ball in the winning area 43 is provided below 21.422.

This detection switch 44b constitutes a part of the counting means.

An opening/closing drive mechanism 45 is coupled to the opening/closing plate 41 . The opening/closing drive mechanism 45 includes a solenoid 451, a T-shaped lever 453, a rod 455, and a spring 456. The center of the T-shaped lever 453 is rotatably attached to the mounting plate 31 by a pin 454. One end of the short side of the T-shaped lever 453 is engaged with a plunger 452 of a solenoid 451, and a spring 456 is connected to the other end of the short side of the lever 453. In addition, ■-shaped lever 4
One end of a rod 455 is engaged with the long side end of 53;
The other end of the rod 455 is connected to the side wall of the opening/closing plate 41 and the bottle 413.
are connected by. When the solenoid 451 is electrically deenergized, the other end of the short side of the T-shaped lever 453 is pulled by the spring 456, so that the lever 453
The tip of the long side is pulled down, and a downward force is applied to the side wall of the opening/closing plate 41 by the rod 455, so that the opening/closing plate 41 is in a closed state. Conversely, when solenoid 451 is electrically energized, T-shaped lever 45
3 is rotated clockwise (clockwise in FIG. 4A), the rod 455 is pulled upward, and the rRm plate 4 is opened in one direction.

In this embodiment, the variable winning ball device 140 is in the open state in which the opening/closing plate 41 is easy to win a ball in the first state, which is advantageous to the player, and in the second state, which is disadvantageous to the player. The case where the opening/closing board 41 is closed and the balls cannot win a prize has been explained. However, the structure of the variable winning ball device and the state of change between the first state and the second state are not limited to those of the above-mentioned embodiments, and may take on various structures and states. For example, as another example of a variable display device, like a so-called tulip, in a first state that is advantageous to the player, a pair of ball receiving pieces open left and right, making it easy for balls to win. In the second state, which is disadvantageous to the player, the ball receiving piece may be closed, making it difficult for the ball to win. Further, the variable prize winning ball device has a configuration including an opening/closing plate provided on the game board 1 so as to be openable and closable, and a ball socket capable of receiving one ball provided on the top of the opening/closing plate, and a second In the first state, the opening and closing board is closed, and balls can only be won at the ball entrance provided at the top of the opening and closing board, and there is a low probability of winning. It is also possible to configure the system so that winnings occur based on probability.

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

The rotating drum display mechanism 50A has a configuration as shown in FIG. Referring to FIG. 5, the rotating drum group 51 is
It includes multiple rows of rotating drums 51a, 51b, and 51c. Identification information such as pictures, symbols, and numbers (for example, bell, N,
A picture pattern such as a sailboat or symbols such as numbers or the alphabet) are drawn on it. Rotating drum 51a in each row
~ On each side of 51C, there is a ratchet gear 52 having the number of teeth corresponding to the number of identification information drawn on the outer periphery.
a to 520 (only 520 is shown in the figure) are fixed. Each of the rotating drums 51a to 51c in each row is loosely fitted onto a drum shaft 53 and supported so as to be rotatable individually by the frictional force thereof. drum shaft 53
is pivotally supported on both sides by the side surface of the box 54, and a gear 551 included in the rotational force transmission mechanism 55 is fixed to one end of the drum shaft 53. The gear 551 meshes with a gear change gear 552. A motor 56 for driving the rotating drum is mounted on the side of the box 54. Motor 56 is a geared motor, and its drive gear is engaged with gear 552. Therefore, the rotational force of the motor 56 is transmitted to the drum shaft 53 via the gears 552 and 551, and the rotating drum group 51 is rotationally driven.

On the rear back side of the box 54, each row of rotating drums 51a
Solenoids 57a to 57C for individually controlling rotation or stopping of each of 51c to 51c are fixed. Plungers 571 of solenoids 578 to 57C are connected to one ends of locking levers 58a to 58c, respectively, by pins. Approximately central portions of the locking levers 58a to 58c are
It is supported by a shaft 581, and both ends of the shaft 581 are connected to the box 54.
is supported on both sides. Locking levers 58a to 58c
A claw-like portion 582 is formed at each tip. The claw-like portions 582 of each of the locking levers 58a to 58C
engages with each of the corresponding ratchet gears 528-52c to stop the rotating drums in each row and maintain the locked state.

The specific game state in which the variable winning ball device 40 can be put in the first state is a combination state of identification information such as a picture pattern in each row displayed on the rotating drum display mechanism 50A, and a segment display! Note that the specific game state is determined by the combination with the display state of the numerical information displayed in the rotary drum display mechanism 5OA. It's okay.

Alternatively, without using the rotating drum display mechanism 50A, a plurality of segment displays capable of electrically displaying numbers 0 to 9 are arranged, and the decision is made based on the combination of display information of multiple digits displayed by the segment displays. It may be possible to do so.

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

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

The specific game state detection circuit 64 is connected to the rotating drum display mechanism 50.
A display status and segment display! This is a circuit for detecting that a predetermined specific gaming state has been entered based on a combination with the display state of 150B. In addition, in this embodiment, the specific gaming state detection circuit 65 detects not only a specific gaming state but also a gaming state in which a smaller gaming value can be given than the specific gaming state, and the variable winning ball device 40 is set to the first state. Contains a function to detect conditions that can result in a state. Therefore, in this embodiment, there are a wide variety of gaming states, making the pachinko gaming machine more interesting for players. The predetermined number of winning balls detection circuit 65 is a circuit that counts the number of winning balls in the variable winning ball device 40 in a specific gaming state and derives a detection output when the number of balls reaches a predetermined number allowed in advance. be. The predetermined value giving state detection circuit 66 is a circuit for detecting a state in which a predetermined value is given in a specific game state (for example, a state in which a large number of prize balls set as the number of prize balls to be discontinued is paid out).

The numerical information display drive circuit 67 is a predetermined winning ball number detection circuit 6
This is a circuit for driving a numerical information display 6 to display a predetermined numerical value based on the output of the numeral 5.

FIG. 7 is a circuit diagram showing an example of a detailed configuration of the drive control circuit 70 and the predetermined number of winning balls detection circuit 65, which are the features of this embodiment, of the game control circuit shown in FIG. 6.

Referring to FIG. 7, the drive control circuit 70 includes an OR gate 7
1. Timers 72 to 74, driver 75 and constant
(a) includes a repetitive opening/closing drive circuit 76; Here, driver 7
5 is for driving the variable winning ball device 40 to the first state by energizing the solenoid 451 during the output period of the OR gate 71. The driving circuit 76 that repeatedly opens and closes for a certain period of time basically puts the variable prize ball @40 into a state where it is easy to win continuously for a certain period of time (for example, t1-30 seconds).

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

The player puts the ball borrowed from the ball lending machine into the ball waiting gutter 13,
After adjusting the strength of the ball by rotating the ball-hitting handle 14, the ball-hitting switch 14s is pressed. In response to pressing the ball hitting switch 148, power is supplied to the motor 241, and the motor 2
41 is rotationally driven and the ball hitting hammer 243 is intermittently rotated, whereby balls are driven into the game board 1 one by one. In this way, when the player is playing a ball hitting game, the ball is either in one of the safe holes 2a to 2C or in the Yakumono 4.
When winning a or 4b, the prize ball discharging mechanism is activated and a predetermined number of prize balls are controlled to be released for each winning ball.

Further, when a hit ball lands in any of the winning areas 38 to 3C, the corresponding detection switch 22a or 22b derives a high level signal, this signal is given to the drive circuit 621 via the OR gate 611, and the timer 622
given to. Further, the high level output from the OR gate 611 is applied to the flip 70 knob 631 included in the display drive circuit 63, and sets the flip 70 knob 631. Based on the signal from the OR gate 611, the drive circuit 621 energizes the solenoids 578 to 57c to release the engagement between the pawls 582 of the locking levers 58a to 580 and the corresponding ratchet gears 52a to 520. , simultaneously drives the motor 56 to rotate. As a result, the rotating drums 51a to 510 in each row are rotationally driven, and the display state of the rotating drums is varied. Also, flip-flop 63
The set output of 1 is given as one input of AND gate 632. The AND gate 632 has a low output oscillation 1.
The output clock pulse of 633 is always given as the other input. Therefore, the AND gate 632 derives a clock pulse according to the set output of the flip 70 knob 631 and supplies it to the 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 the counted value is sent to the decoder driver 63.
5 and a determination circuit 645 included in the specific game state detection circuit 64. The decoder driver 635 decodes the count value of the ring counter 634, and based on the count value, sequentially changes the number displayed on the segment display 50B in synchronization with the cycle of the clock pulse.

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

As described above, in a state where the rotating drums 51a to 51c and the segment display 50B are variably displayed, the player can select the rotating drums 51a to 51c in each row.
The player presses the stop command switch 17 at an arbitrary timing, expecting that the combination of display states will result in a specific gaming state. Note that the timer 622 starts after the variable display starts.
If the stop command switch 17 is not pressed within a certain period of time set in , a stop command is issued by the output of the timer 622. In response to the output from the press of the stop command switch 17 or the output from the timer 622, the drive circuit 621 deenergizes the solenoids 57a to 57c in a predetermined order (or irregular order), and accordingly deactivates the locking levers 58a to 58c. Ratchet gears 528 to 52G corresponding to the claw-like portions 582 of
are engaged with each other, and the rotating drums 51a to 510 are sequentially stopped. Furthermore, the drive circuit 621 stops the rotation of the motor 56 after a short delay and derives a high level signal indicating that all rotating drums have stopped. This high level signal resets the flip-flop 631 and is given to the display state determination circuit 643 as a determination command signal. Resetting flip-flop 631 causes ant gate 632 to stop deriving clock pulses. For this reason, the count value of the ring counter 634 stops moving, and therefore the count value of the ring counter 634 stops moving.
Numbers corresponding to the count value counted at 4 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. Incidentally, in this embodiment, the sensors 641 and 642 are configured as charging sensors having a light projecting section and a light receiving section. The light emitting part and the light receiving part of each sensor 641 and 642 are provided facing each other on the axially outer side of the rotating drum. Although not shown in FIG. 5, on the side surfaces of each of the rotating drums 51a to 510, there is a rotary ring on a first circumference and a second circumference, which are shells of concentric radii. A portion with a through hole and a portion without a through hole are formed at positions corresponding to the identification information displayed on the drum. And each rotating drum 51a to 51
Four types of identification information are output depending on the stop state of 0. For example, if the portions on the first and second circumferences where holes are drilled are set to logic "1", and the portions where holes are not drilled are set to logic "0", then 4 2-bit code roOJ, ro"IJ,
10J, rlIJ can be defined, and the combination of identification information of the rotating drums in each row can be detected.
A score is determined based on the combination of identification information displayed as 0, and the score is provided to the drive control circuit 70 and the determination circuit 645.

If the combination of identification information displayed on the rotating drums 51a to 51G is not a combination of a specific gaming state, that is, a combination determined to give the maximum value (for example, all symbols A), the display state The determination circuit 643 derives one of the determination signals j2 to j4 indicating that a value smaller than the maximum value should be assigned based on the combination at that time. Each determination signal j2-j4 is given to a corresponding timer 72-74. Each timer 72, 73, 74 outputs a corresponding judgment signal j2. Depending on the input of j3゜j4, a predetermined fixed time t2, t3.
A high level signal is derived for t4. Here, the constant darkness set by the timers 72 to 74 is t
2≧t3≧t4, for example, t-io seconds,
It is said that t is 3-6 seconds and t is 4-4 seconds. Note that the determination circuit 645 determines that the determination signal is other than j1 (that is, j2 to j4
), the display state of the segment display 50b is not determined at all.

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

This high level signal is applied to the driver 75 via the OR gate 71. Accordingly, the driver 75 operates ff at a certain time.
The solenoid 451 is continuously energized by 1t2. Therefore, the opening/closing plate 41 of the variable winning ball device 40 is opened for a certain period of time t2 to allow the hit ball to win. At this time, when the hit ball lands in any of the winning areas 438 to 43c, the prize dispensing mechanism pays out a predetermined number of prizes depending on the winning area. In this case, even if the hit ball enters the winning area 43a, the opening/closing operation of the variable prize ball mounting M40 is not controlled to extend.

Next, a case will be described in which the combination of identification information displayed on the rotating drums 51a to 51c in each row is determined to give the maximum value. In this case, the display state determination circuit 643 derives a determination signal j1, and this signal j1 is given to the determination circuit 645, and the flip 70 knob 7
61 reset input. Accordingly, the flip 70 knob 761 is set. In addition, the determination circuit 645
is the display It (for example, a state in which 7 is displayed) to which the maximum value to which the count value of the ring counter 634 is set in the combination setting section 644 according to the judgment signal j1 is to be given.
Determine whether or not. At this time, the determination circuit 645 determines that even if the combination of display states of the rotating drums 51a to 510 gives the maximum value, the segment display 5
0B displays the number 7. If not, the maximum value imparting command signal jO (high rail signal) will not be derived. In this case, the set output of the flip 70 knob 761 set by the determination signal j is given to the timer 763 via the OR gate 762. In response, the timer 763 starts counting operation for a certain period of time t1, derives a high level signal during that period, and the high level signal is transmitted to the transistor 764.
given to the collector. At this time, the transistor 76
4, the mismatch output (low level) of the comparison circuit 653 is inverted to high level by an inverter 655 and is applied. Therefore, transistor 764 is conductive during the period when comparator circuit 653 derives a mismatch output;
The output of timer 763 is given to driver 75 via OR gate 71. In response, driver 75 operates solenoid 45
1 to open the opening/closing plate 41. In this case, AND gates 651 and 767 remain disabled because flip 70 knob 766 is not set. Therefore, the predetermined winning ball number detection circuit 65 does not detect the winning balls that have entered the winning area 43a, and the variable winning ball KA
Do not repeat @40 to prepare for opening. Then, when the timer 763 measures a fixed time 11t1, its output becomes a low level, so the opening/closing plate 41 is closed.

Next, when a specific game state is reached, which is a feature of this embodiment, that is, a combination of the display states of the rotating drums 51a to 51c is in a predetermined state that can give the maximum value (for example, the display state B with all A symbols ) and the display state of the segment display device 50B is in a state where 7 is displayed, the operation will be explained.

A determination circuit 645 derives a high level signal indicating that a specific gaming state has been established and supplies it to an AND gate 646. At this time, since the low level of the output of the predetermined value provision state detection circuit 66 is inverted to a high level and is applied to the AND gate 646, a high level determination signal jO is derived from the AND gate 646. Decision signal jO sets flip-flop 766. Therefore, when a specific gaming state is entered, the aforementioned rotation i-rams 1a to 51. Only in the display state c, the maximum value is given and the operation in the S state is performed, and the repeat value giving operation based on the specific gaming state is performed. That is, the timer 763 derives a high level by a constant l1111t1 from the time when the determination signal j1 is applied, drives the driver 75, and opens the opening/closing plate 41. At this time, the AND gate 651 is activated by the set output of the flip 7O tube 766. Therefore, when a ball is hit into any of the winning areas 438 and 430, it is detected by the detection switch 44b. Detection switch 44b
The detection output of is sent to the counter 65 via the AND gate 651.
given to 2. The counter 652 counts the number of winning balls in the winning areas 43a to 43C in a specific gaming state,
The counted value is given to comparison circuit 653 and numerical information display drive circuit 67. The comparison circuit 653 receives as a reference input the number of winning balls (for example, 10) that can be won in the variable player prize ball M40 in the specific gaming state set by the setting section 654. The comparison circuit 653 is a counter 654
When the count value of is smaller than the set number, a low level signal is derived. This 0-level signal is inverted to a high level by an inverter 655 and applied as the base input of a transistor 764, so that the transistor 764 applies a high level signal of the output of the timer 763 to the OR gate 71.

Further, the count value of the counter 652 is displayed on the numerical information display 16 by the numerical information display driving 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 gaming state, and how many winning balls are allowed. You can easily find out if there are any. Therefore, there is an advantage that the player can easily formulate a strategy for the game based on this display.

If there is a predetermined number of allowed winning balls before the timer 763 times up, the comparison circuit 653 derives a high level signal. This high level signal is transmitted to inverter 6
55 to a low level signal, and the transistor 764
is turned off, and the high level output of timer 76ζ:1 is not derived. In this way, when the specified gaming state is entered, when the number of winning balls in the winning area reaches a predetermined number before the timer 763 has elapsed, the solenoid 451 is deenergized and the opening/closing plate 4
1 is closed. At this time, the output of the inverter 655 is passed through the OR gate 765 to the differential circuit 767.
is given to , and differentiated in the falling direction.

This differential pulse is then given to the monostable multi 768, and the monostable multi 768 derives a high level signal for a certain period of time. Its output is applied to AND gate 769.76a and causes flip-flop 761 to be reset.

By the way, when a ball enters the winning area 43a during the period when the variable winning ball device 40 is being driven to open after the specific game state, the detection switch 44 outputs a detection output and sets the flip 70 knob 76b. Therefore, the AND gate 769 determines that there is a set output of the flip 70 knob 766 (that is, that it is in a specific gaming state),
There is a set output of the flip-flop 76b (that is, a condition that allows the variable winning ball device 4o to be repeatedly opened is detected) and there is an output of the monostable multi 768 (that is, the variable winning ball device 40 is opened). Based on this, a high level signal is derived, and the high level signal is applied to a timer 763 via an OR gate 762. In response, the timer 763 again starts counting operation for a certain period of time t1, and derives a high level signal during that period. This high level signal is applied to the driver 75 via the transistor 764 and the OR gate 71, and the renoid 451 is activated. Therefore, 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.

In addition, after a certain time delay from the output of the monostable multi-768,
Delay circuit 76c is configured to reset flip-flop 76b. In this case, the reset output of the flip-flop 76b is given to the AND gate 76a, but at this time, the output of the monostable F-768 is no longer given as the other input of the AND gate 76a, so the AND gate 76a is Do not derive high level signals.

Thereafter, in the same way, after a specific gaming state, one cycle is defined as a certain period of time t1 (for example, 30 seconds) or until a predetermined number of winnings (for example, 10) that are allowed during one opening period occur. As long as there is a prize in area 43a,
The cycle repeats. Therefore, 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 number of winning balls during one opening period of the variable winning ball device 40 is limited to a predetermined number or less. At the same time, it has the advantage of being able to repeat the winnings many times, allowing the player to maintain an advantageous state for a long time, and enlivening the atmosphere of the game.

In addition, when the variable winning ball device f40 is repeatedly driven to open, if no ball enters the winning area 43a, the flip-flop 761) remains reset. Therefore, in this case, monostable multi 76
AND gate 76a derives a high level signal in response to the output of 8, and resets flip 70 knob 766 via OR gate 76d. As a result, variable winning ball device 4
The repeated opening drive operation of 0 is terminated.

After the specific game state, each time the variable winning ball device 40 is repeatedly driven to open, if a ball enters the winning area 43a, the repeated opening operation of the variable winning ball device 240 is continued. However, when the predetermined value award state detection circuit 66 detects that a predetermined number (stopped number) of prize balls (for example, 2000 pieces) have been paid out, the detection output is sent to the flip 70 via the OR gate 76d. 766 and flip 70 knob 766 is reset. This also ends the repeated opening/closing driving operation of the variable prize ball mounting @40.

In this embodiment, the predetermined value awarding state detection circuit 66 derives a detection output when a fixed number of prize balls are paid out, but the predetermined value awarding state detection circuit 66 may be used for example with a variable winning ball device! It may be configured such that the number of repeated openings of 40 is counted and the detection output is derived when the number of times reaches a certain number, for example, 18 times.

Furthermore, in the above-mentioned embodiment, as the repetition condition detection means,
Although a case has been described in which there is one or more winnings in the winning area 43a during the opening period of the variable player prize ball M40 in the specific game state, other repeating conditions may be detected. For example, the number of balls won in any of the winning areas 438 to 43c is smaller than the number of balls (for example, 10) detected by the predetermined number of winning balls detection circuit 65 (for example, 3 balls).
It may be configured such that the repetition condition is detected when there are more than 1). In that case, a comparison circuit is separately provided to detect that the counter 652 has counted the small number of winning balls (3), and the output of the comparison circuit is used to connect the flip-flop 76b.
The configuration may be configured so that .

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

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

In the embodiments shown in FIGS. 6 and 7 described above, a case was shown in which a hardware circuit was used to explain the present invention in detail, but the technical idea of the present invention is that it is constructed by program processing using a microprocessor. You can also do it. In that case, the program can be set to perform the circuit operations shown in Figures 6 and 7, but since such program settings can be easily devised by those skilled in the art who are familiar with electronic technology, please refer to the detailed information below. Explanation will be omitted.

[Effects of the Invention] As described above, according to the present invention, the variable winning ball device is set in a state where it is easy to win a prize based on a specific gaming state, and the number of paid balls during that period reaches a certain allowed number. When,
Or, a pachinko game machine that changes the variable winning ball device to a state in which it is difficult to win when a certain amount of time passes without reaching a certain number, and the number of winning balls until the allowed number of winning balls is reached is displayed. Because of this configuration, it is possible to inform the player of the progress of the game, which has the effect of making it easier for the player to plan a game strategy based on the display. Moreover, since the display contents change every moment according to the number of winning balls, the gaming machine can liven up the atmosphere of the game and arouse the interest of the players.
