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, a pachinko game machine has multiple safe holes and winning ball devices on its 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 No. 54-14.5644, the applicant of the present application previously proposed that a variable winning ball device such as a Yakumono be used to win a prize for a relatively long time based on a specific gaming state. We proposed a pachinko game machine that makes it easy to win a large amount of prizes at once.

[Problems to be Solved by the Invention] However, the previously proposed method merely puts the variable winning ball device in a state in which it is difficult to win for a relatively long time, and therefore Depending on the adjustment state of the nails planted in the machine, there are cases where more than 10 winning balls will be produced during one opening period of the variable winning ball device, and others where no winning balls will be produced at all, depending on the platform. There were times when the probability of winning a prize 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.

Further, in the previously proposed pachinko game machine, the variable winning ball device is opened for a certain period of time based on a specific game state, and is once opened and then opened again based on a condition that allows it to be opened repeatedly. However, there is no restriction on the winning balls that can be won during the period when the variable winning ball device is opened once.

Therefore, the main purpose of the present invention is to make it easier to win with the variable winning ball device based on a specific gaming state and to repeatedly put the variable winning ball device into a state where it is easier to win. In order to make it easier to win, we will limit the number of balls that can be won during the period when the variable winning ball device is made easier to win, limit the variation among pachinko machines to within a certain range, and make it easier to win once. To make it easier to win a prize with the 10 variable player prize ball device depending on the game state, the number of repetitions can be increased.

[Means for Solving the Problems] This invention has an upper limit for the number of winning balls that can be won while the variable winning ball device is opened once, and the variable winning ball device can be opened based on repeated conditions. This pachinko game machine is one in which control is performed repeatedly, and a special prize area for generating repeat conditions is provided in a part of the winning area of a variable winning ball device.

[Operation] In response to entering the specific game state, the drive control means puts the variable winning ball device into the first state advantageous for the player for a certain period of time. After this state, the ball hit by the player will win a prize in the variable prize winning ball device with a relatively high probability. The number of all winning pachinko balls is counted, and when the number reaches a certain number allowed within a certain period of time, the variable winning ball device is driven to the second state. In addition, during the period of the first state, if a pachinko ball wins a special prize area formed in a part of the winning area of the variable winning ball device, the output of the repeating condition detection means is derived, and the output is determined based on the output. The drive control means once puts the variable winning ball device in the second state and then returns it to the first state.
The drive is controlled to the following state.

[Embodiments of the Invention] Specific embodiments of the invention will be described below with reference to the drawings.

FIG. 3 is a perspective view of the variable winning ball/variable display device 30. 4A and 4B show the details of the variable winning ball device 40, in particular, FIG. 4A shows the details of the variable winning ball device 40 seen from the back side of the variable winning ball/variable display device 30, and FIG. 4B shows the details of the variable winning ball device 40. FIG. 3 is a vertical cross-sectional view of the winning area portion of the variable winning ball device 40.

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 B position 30 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 display windows 33a and 33b for displaying identification information drawn on the rotating drum included in the rotating drum display mechanism 50A.
, 330 are formed. Furthermore, a frame member 34 is attached to the top of the mounting plate 31. Frame member 34
A segment display 50B is attached to the segment display 50B, and an inverted V-shaped ball receiving plate 341 is attached to the upper part of the segment indicator 50B.The ball received by the ball receiving plate 341 becomes the winning area II!3a. It is designed to be guided to the back side through the hole.Furthermore,
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 the upper part of the opening 32 in the approximate center of the mounting plate 31. It is set up. 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 positions 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 40 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 opening 32). Triangular side walls 411.4-12 protruding toward the back side are provided on both side edges of the opening/closing plate 41. The side walls 411, 412 are rotatably attached to the side surface of the frame member 42 via a shaft 413. Paths 421 and 422 are formed below the frame member 42. Frame member 4
2 is covered with a cover 423. When the opening/closing plate 41 is in the open state, the opening 32 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 C. Among the winning areas divided in this way, the winning area 43a is capable of opening the opening/closing plate 41 again with a winning ball during opening of the opening/closing plate 41 in a specific game state, and putting the variable winning ball device 40 into a state where it is easy to win a prize. This is a so-called special prize area where such conditions are set.

The feature of this embodiment is that the special prize area is formed in a part of the winning area of the variable winning ball device 40 in this way. By forming the special prize area 438 in a part of the winning area in this way, there are the following advantages. That is, while the opening/closing board 41 is open in a specific game state, the player shoots pachinko balls aiming at the winning area 43 that is being opened. At this time, since a part of the area is the special prize area, there is a high probability that a ball fired aiming at the winning area will also win the special prize area at the same time, creating advantageous conditions for the player. The pachinko game machine can be improved and more interesting.

A detection switch 44a is provided in association with a winning area 43a which is a special prize area. The detection switch 44a is for detecting a winning ball in the winning area 43a. The output of this detection switch 44a is given to the drive control means as a repetition condition detection output as will be described later, and the variable winning ball device 40 repeats 1ItlJ 1!11.

Further, the winning balls in the winning areas 438 to 43c are guided downward via paths 421 and 422, respectively. Route 4
21, 422, a detection switch 44b for detecting a winning ball in the winning area 43 is provided.

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. Furthermore, the T-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 in the time B1 direction (clockwise in FIG. 4A), and the rod 455 is pulled upward to close the opening/closing plate 41.
is opened forward.

In this embodiment, the variable prize winning ball device 40 is in the state where the opening/closing plate 41 is opened in which it is easy to win a ball in the first state where it is advantageous for the player, and it is disadvantageous for the player. In the second state, the opening/closing plate 41 is opened and the ball cannot win a prize. 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,
It can take on a variety of structures and states. For example, as another example of a variable winning ball device, in the first state where the player is right-handed, such as a so-called du-rip, a pair of ball receiving pieces open left and right, making it easy for the ball 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. Variable display device 50 includes a rotating drum display mechanism 50A and a segment display 50B.

The rotary drum display m50A 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, bells, stars,
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
A ratchet gear 52a having a number of teeth corresponding to the number of identification information drawn on the outer periphery is provided on each side of ~51c.
~52C (only 52c is shown in the figure) is 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 individually rotatable by the frictional force thereof. The drum shaft 53 is
Both sides of the box 54 are pivotally supported, 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. On the side of the box 54,
A motor 56 is mounted to drive the rotating drum. 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 5 through the gears 552 and 551.
3, 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. The plungers 571 of the solenoids 57a to 57C are
Each is connected to one end of the locking levers 58a to 58c by a pin. Approximately central portions of the locking levers 58a to 58c are supported by a shaft 581, and both ends of the shaft 581 are connected to the box 5.
It is supported on both sides of 4. Locking levers 58a to 58
A claw-like portion 582 is formed at the tip of each of the portions c. The claw-like portions 58 of each of the locking levers 58a to 58C
2 engages with each of the corresponding ratchet gears 52a to 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 determined by the combination of identification information such as the picture pattern in each row displayed on the rotating drum display mechanism 50A and the segment display 50B. The specific game state is determined by the combination with the display state of the numerical information displayed. Note that the specific game state may be determined only by the combination of the identification information displayed on the drums in each row of the rotating drum display mechanism 50A. .

Alternatively, without using the rotary drum display mechanism 50A, a plurality of segment displays capable of electrically displaying numbers O 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 (=I given). The 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 rotating drum drive control circuit 62 is a circuit for driving and controlling the rotating drum display mechanism 50A based on variable display possible conditions.The display drive circuit 63 is a circuit for driving and controlling the rotating drum display mechanism 50A based on variable display possible conditions. This is a circuit for display-driving the device 50B.

The specific game state detection circuit 64 is connected to the rotating drum display mechanism 50.
This is a circuit for detecting that a predetermined specific gaming state has been entered based on a combination of the display state of A and the display state of the segment display 50B. 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 small game value can be given than the specific gaming state, and the variable winning ball device 40 is Contains a function to detect conditions that can lead to the state. For this reason,
In this embodiment, the type of gaming state is Q wealth, 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 65
This is a circuit for displaying a predetermined numerical value on the numerical information display 6 based on the output.

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, drive control circuit 70 includes OR gate 7
1. It includes timers 72 to 74, a driver 75, and a circuit 76 for repeatedly opening and closing for a certain period of time. Here, the driver 75 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 constant time repeated opening/closing drive circuit 76 basically puts the variable winning ball device 40 into a state where it is easy to win a prize continuously for a certain period of time (for example, tl=30 seconds).

Next, the specific operation of the Pachin=I gaming machine 10 of this embodiment will be explained with reference to FIGS. 1 to 7.

The player places the J borrowed from the ball lending machine into the ball 11113 when hitting the ball, turns the ball hitting handle 14 to adjust the strength of the ball, and then
Hitting ball switch 143 is pressed. In response to the depression of the ball hitting switch 143, power is supplied to the motor 241, which rotates and rotates the ball hitting hammer 243 intermittently, thereby driving balls into the game board 1 one by one. When a player is playing a ball hitting game in this way,
When a hit ball enters any of the safe holes 28 to 2C or the Yakumono 4a or 4b, a prize release mechanism is activated to control the release of a predetermined number of prizes for each winning ball.

Further, when a hit ball lands in any of the winning areas 3a 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 a flip-flop 631 included in the display drive circuit 63, and sets the flip-flop 631. Based on the signal from the OR gate 611, the drive circuit 621 energizes the solenoids 578 to 57C to release the claw-like portions 582 of the locking levers 58a to 58c from their engagement with the corresponding radiet gears 528 to 52G. , simultaneously drives the motor 56 to rotate. As a result, the rotating drums 518 to 51C 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 output clock pulse of the clock oscillator 633 is always applied to the AND gate 632 as the other input. Therefore, the AND gate 632 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 510 and the segment display 50B are variably displayed, the player can select the rotating drums 51a to 510 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 578 to 57C in a predetermined order (or irregular order), and accordingly deactivates the locking levers 58a to 58c. Ratchet gears 52a to 52c corresponding to the claw-like portions 582 of
are engaged with each other, and the rotating drums 51a to 51c 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 incrementing, and therefore the count value of the ring counter 634 stops increasing.
Numbers corresponding to the count value increased by 4 to 81 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 composed of photoelectric 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 outer side of the white image in the axial direction of the rotating drum. Although not shown in FIG. 5, on each side surface of the rotating drums 51a to 510, on a first circumference and a second circumference concentrically having different 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 rotating drum. And each rotating drum 51a-5
Four types of identification information are output depending on the 10 stop states. For example, the portions on the first and second circumferences where through holes are drilled are designated as logical “1”.
If the part where the hole is not drilled is logical rOJ, then four types of 2-bit codes [ool, rolj, r
loJ and MIJ can be defined, and the combination of identification information of the rotating drums in each row can be detected. Then, the display state determination circuit 643 determines the score based on the combination of identification information displayed on the rotating drums 518 to 51C, and provides the score to the drive control circuit 70 and the determination circuit 645.

If the combination of identification information displayed on the rotating drums 51a to 51c is not a combination of a specific gaming state, that is, a combination determined to give the maximum value (for example, all symbols A), the display state The judgment circuit 643 derives one of judgment signals j2 to j4 indicating that a value smaller than the maximum value should be given based on the combination of the pieces. 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 fixed time set by the timers 72 to 74 is t
2≧t3≧t4, for example, t=io seconds,
It is assumed that t3=6 seconds and t4=4 seconds. Note that the determination circuit 645 determines that 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.

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

This high level signal is applied to the driver 75 via the OR gate 71. Accordingly, the driver 75 operates for a certain period of time t.
2 continuously energizes the solenoid 451. Therefore, the opening/closing plate 41 of the variable winning ball device 40 is opened for a certain period of time t2 to allow the hit ball to win. At this time, when the hit ball lands in any of the winning areas 43a to 43c, the prize ball discharging mechanism pays out a predetermined number of prize balls according to the winning ball. In addition, in this case, the ball hit is in the winning area 43.
Even if a prize is won in a, the opening/closing operation of the variable winning ball device 40 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 510 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 set inputs. Accordingly, flip-flop 761 is set. In addition, the determination circuit 645
determines whether the count value of the ring counter 634 is in a display state (for example, state R where 7 is displayed) in which the maximum value set in the combination setting section 644 should be given, according to the determination signal j1. do. At this time, the determination circuit 645
Even if the combination of display states of the rotating drums 51a to 51C is the state that provides the maximum value, the segment display device 50
If B does not display the number 7, the maximum value assignment command signal jO (high level signal) is not derived. In this case, the flip 70 knob 76 set by the determination signal J1
The set output of 1 is sent to the timer 76 via the OR gate 762.
given to 3. In response, the timer 763 starts a certain period of time t1.
starts a timekeeping operation, derives a high level signal during that period, and the high level signal is applied to the collector of transistor 764. At this time, the mismatch output (low level) of the comparison circuit 653 is connected to the base of the transistor 764.
is inverted to a high level by an inverter 655 and provided. Therefore, transistor 764
53 is conductive during the period when timer 763 is outputting 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 detection circuit 65 does not detect the winning balls in the winning area 43a, and the variable winning ball game M40
Do not perform any preparatory actions for repeated opening. Then, when the timer 763 measures a certain period of time t1, its output becomes low level, so the opening/closing plate 41 is closed.

Next, when a specific game state, which is a feature of this embodiment, is reached, that is, a predetermined state in which the combination of display states of the rotating drums 51a to 51c can give the maximum value (for example, a display state of all A symbols) The operation when the display state of the segment display 50B becomes 7 will be explained. ``The determination circuit 645 derives a high level signal indicating that a specific gaming state has been established, and applies it to the AND gate 646. At this time, since the low level of the output of the predetermined value provision state detection circuit 66 is inverted to 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, only the above-mentioned display states of the rotating drums 51a to 51c are operated in accordance with the determination signal j1 when the maximum value giving state is reached, and the repetition based on the specific gaming state is performed. A value-adding action is performed. That is, the timer 763 derives a high level for a certain period of time [1 from the time when the determination signal j1 is applied, drives the driver 75, and opens the opening/closing plate 41. At this time, and gate 6
51 is activated by the set output of flip-flop 766. Therefore, the hit ball is in the winning area 43a.
, 43c, the detection switch 44
b. The detection output of the detection switch 44b is applied to a counter 652 via an AND gate 651. The counter 652 adds up the number of man-hours won in the winning areas 43a to 43C in the specific gaming state, and provides the counted value to the comparison circuit 653 and the numerical information display drive circuit 67. The comparison circuit 653 receives as a reference input the number of winning balls (for example, 10) that can be played in the variable winning ball device 40 in the specific gaming state set by the setting section 654. Comparison circuit 653 derives a low level signal when the sub value of counter 654 is smaller than the 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 player prize ball device 40 in a specific gaming state, and how many more balls are allowed to be won. You can also easily find out what is happening. 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 winnings allowed before the timer 763 times up, the comparison circuit 653 derives a high level signal. This high level signal is sent to inverter 6
55 to a low level signal, and the transistor 764
is turned off, and the high level output of timer 763 is not derived. In this way, when the specific gaming state is entered, when the number of winnings in the winning area reaches a predetermined number before the one move time t1 set by the timer 763 has elapsed, the solenoid 451 is forcibly turned off. 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 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 resets flip-flop 761.

By the way, during the period when the variable winning ball device 40 is driven to open after the specific game state, when a ball enters the winning area [43a], the detection switch 44 outputs a detection output and sets the flip-flop 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),
Based on the fact that there is a set output of the flip-flop 76b (that is, that a condition that can repeatedly open the variable winning ball device 40 is detected) and that there is an output of the monostable multi 768 (that is, that the variable winning ball game M40 is opened) 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 driver 75 via transistor 764 and OR gate 71, and solenoid 451 is energized. 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 76G is configured to reset flip-flop 76b. In this case, the reset output of the flip 70 knob 76b is given to the AND gate 76a, but at this time, the output of the monostable multi 768 is no longer given as the other input of the AND gate 76a, so the AND gate 76a goes high. Do not derive level signals.

Thereafter, in the same way, after a specific gaming state, one cycle is defined as a certain period of time tl (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 Bananco 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 game M40 is limited to a predetermined number or less. In addition, 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 enhancing the atmosphere of the game.

Note that when the variable winning ball device 40 is repeatedly driven to open and open, if no ball enters the winning area 43a, the flip-flops 76 and 76b remain reset. Therefore, in this case, monostable multi 768
The AND gate 76a derives a high level signal in response to the output of the flip 70 knob 7 via the OR gate 76d.
66 is reset. As a result, the variable winning ball device 40
The repeated opening drive operation of is completed.

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 40 is continued. However, when the predetermined value imparting state detection circuit 66 detects a predetermined number (stopped number) of prize balls (for example, 2000 pieces)
If it is detected that the payout has been made, the detection knob J is applied to the flip knob 766 via the OR gate 76d, and the flip knob knob 766 is reset. This also ends the repeated opening/closing driving operation of the variable winning ball device 40.

In this embodiment, the predetermined value awarding state detection circuit 66 derives the detection output when a fixed number of prize balls are paid out, but the predetermined value awarding state detection circuit 66 is configured to, for example, It may be configured such that the number of repeated openings is divided by a number 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 winning balls in the winning area 43a during the opening period of the variable winning ball device 40 in a specific gaming state, other repeating conditions may be detected. For example, if the number of man-hours for winning a prize in any of the winning areas 43a to 43C is greater than or equal to the number of balls (for example, 10) that is smaller than the number of balls (for example, 10) detected by the predetermined number of winning balls detection circuit 65, the repeat condition is set. It may be configured to detect. 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 input the 7-lip flop 76.
The configuration may be such that b is set.

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.

Furthermore, as another embodiment of the drive circuit 70, an AND gate is provided between the OR gate 71 and the driver 75, and by applying a pulse at a fixed time interval (for example, 2 seconds) to the other input of the AND gate, the variable The winning ball device 40 may be driven to open and close within a relatively long fixed period.

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, in a pachinko game machine that can generate many winning balls with a relatively high probability based on a specific gaming state, the variable winning ball device is operated for a certain period of time. The variable winning ball device can be driven to a state where it is easy to win a prize, or it can be driven to a state where it is easy to win a prize until a certain number of winning balls is generated. Unique effects such as being able to limit variations within a certain range are achieved. In addition, since it is possible to limit the variation in the number of winning balls when the variable winning ball device is in the winning state, it is possible to equalize the service to many players without giving a large amount of prize balls only to a specific player. There is also.

Furthermore, if the variable winning ball device is made to be in a state where it is easy to win in a specific gaming state, and the condition is repeatedly satisfied for a certain period of time or until a certain number of winning balls occur,
Since the variable winning ball device is repeatedly put in a state where it is easy to win, the variable winning ball device can be made into a state where it is easy to win many times, and the special prize area for satisfying the repeat condition is the variable winning ball device. Since it is formed in a part of the winning area, when the variable winning ball device is in the first state, there is a high possibility that the balls fired aiming at the winning area will simultaneously enter the special prize area. The pachinko game machine can be made easy and advantageous for players to play, and the pachinko game machine can provide services to the players.
