Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a pachinko game machine including a game board forming a winning area. This invention relates to a pachinko game machine in which a variable winning ball device that can freely change to a second state that is disadvantageous to the player is arranged on a game board.

[Prior Art] In this type of pachinko game machine, in a conventionally known one, for example, when a predetermined specific game state is entered, the variable winning ball device is set to the first state. The variable winning ball device is controlled to be in the second state based on the elapse of a certain period of time. Further, the first state of the variable winning ball device did not change at all during the period of the first state.

[Problems to be Solved by the Invention] However, in this type of conventional pachinko gaming machine, the first state of the variable winning ball device did not change at all, so the variable winning ball device
There may be cases in which the player does not notice that the state has changed. In other words, the player is absorbed in air-hitting operations during the game, and for this reason, even though the variable winning ball device is urgently switched to the first state that is advantageous to the player. In some cases, the player did not notice this, and by the time he noticed it, the first state of the variable prize winning ball device had ended or was about to end. In such a case, the player would be very dissatisfied, and the original purpose of the pachinko game machine, which is to increase the player's interest, could not be achieved.

Furthermore, in the conventional pachinko game machine, during the period when the variable winning ball device is switched to the first state, the first state does not change, so that the ball is not allowed to enter the variable winning ball device. The probability of winning a prize remains constant and does not change, making the game monotonous and lacking in fun, which also has the drawback of not being able to fully achieve the original purpose of pachinko machines, which is to increase player interest. .

In addition, the first state of the variable prize winning ball device ends after one round, and there is no sustainability, so there is also a drawback that the game lacks interest. Therefore, in order to maintain continuity, repeat continuation control is performed in which the variable winning ball device is driven to the first state again based on the establishment of a predetermined repeating continuation condition during the period in which the variable winning ball device is in the first state. It is also conceivable to configure the system to perform the following. It is also conceivable that a specific area is provided on the game board as the repeat condition, and the repeat condition is satisfied when a ball hits the particular area.

However, if a specific area is provided on the game board other than the winning area of the variable winning ball device, the player can perform a ball hitting operation that causes a ball to enter the variable winning ball device and a ball hitting operation that causes a ball to enter the specific area. There was a problem in that players had to perform two ball-hitting operations, making it difficult to concentrate on the game.

In addition, the variable winning ball device is the first to carry out repeated and continuous control based on the winning of balls in this specific area.
If the condition is limited to only when the repeat continuation condition is satisfied in the state of Therefore, there is a risk that troubles will occur frequently between the gaming hall and the players over what happens after the repeated continuation condition is satisfied after the time when the variable winning ball device changes to the second state. Thus, even if repeated and continuous control is adopted for the purpose of providing players with sufficient satisfaction, a new technical problem arises in that the above-mentioned troubles end up causing dissatisfaction to the players.

In view of the above-mentioned circumstances, the present invention enables the player to fully utilize the advantageous state of the variable prize winning ball device without overlooking it, and eliminates the monotony of the game during the period when the advantageous state is switched. In addition, by adopting repeated continuation control, it gives the player a sufficient sense of satisfaction, allows the player to concentrate on the game, and prevents troubles that occur after the repeated continuation condition is satisfied. An object of the present invention is to provide a pachinko game machine that can prevent such problems.

[Means for Solving the Problems] The present invention provides a game machine which is arranged on a game board and can freely change between a first state that is advantageous to the player and a second state that is disadvantageous to the player. and a variable winning ball device in which the winning area in the first state is divided into a plurality of areas, the plurality of areas are divided into a normal area and a specific area, and at least one of the plurality of areas is the specific area. , a specific gaming state detection means for detecting that the gaming state has become a predetermined specific gaming state; and based on the output of the specific gaming state detection means, the movable member of the variable winning ball device is set to a first state. and second
drive control means for continuously driving and controlling a reciprocating motion that alternately changes the state of the variable winning ball device a plurality of times over a certain period of time; A repeating condition detection means detecting a repeating condition determined to be repeated again; and the drive control means causes the movable member of the variable winning ball device to alternately change between a first state and a second state. a predetermined number of winning balls determining means for determining that the number of winning balls entered into the variable winning ball device has reached a predetermined number when the number of winning balls entered into the variable winning ball device reaches a predetermined number; The reciprocating operation of the variable winning ball device is terminated in response to the presence of an output from the determining means or the absence of an output from the predetermined number of winning balls determining means and a certain period has elapsed, and the variable winning ball device is terminated in response to the output from the repetition condition detecting means. The apparatus is configured to repeat the reciprocating motion of the ball device again, and further includes detectable state maintaining means for maintaining the detectable state by the repetition condition detecting means even after the reciprocating motion of the variable winning ball device ends. It is characterized by

[Operation] The winning area in the variable winning ball device that can freely change between the first state and the second state is divided into a plurality of areas including at least one specific area and at least one normal area. By the function of the specific game state detection means, it is detected that the game state has become a predetermined specific game state, and based on the detection output, the movable member of the variable winning ball device is activated by the function of the drive control means. The drive is controlled so that the reciprocating operation of alternating between the first state and the second state is performed continuously a plurality of times over a certain period of time. Further, when the movable member of the variable winning ball device is alternately changing between the first state and the second state, it is determined that the number of winning balls entered into the variable winning ball device has reached a predetermined number. It is determined by the winning ball number determining means. If a pachinko ball that has entered the variable winning ball device in the first state wins a prize in a specific area, the repeating condition detection means is activated to repeat the reciprocating motion of the variable winning ball device again. A defined repetition condition is detected. Furthermore, if the number of winning balls that have entered the variable winning ball device within the certain period reaches a predetermined number, or if the certain period of time has elapsed without the number of winning balls reaching the predetermined number, the reciprocation of the variable winning ball device The operation ends.
Further, the reciprocating motion of the variable winning ball device is repeated again based on the output of the repetition condition detecting means, and further, the reciprocating motion of the variable winning ball device is completed by the function of the detectable state maintaining means. Even after this, the state in which the repeating condition detecting means can detect the condition is maintained.

In other words, the advantageous state for the player of the variable winning ball device is easy to notice because it consists of a reciprocating motion that alternately changes between the first state and the second state, and the variable winning ball device To prevent a player from overlooking an advantageous condition for a player, and to make full use of the advantageous condition from the beginning. Further, during the period of switching to the advantageous state, the winning probability of the variable winning ball device changes continuously several times, so that the monotony of the game can be prevented and the interest of the game can be improved. Moreover, although it is possible to give players a sufficient sense of satisfaction by adopting repetitive continuation control, the continuation conditions for repeating continuation control are limited to hitting pachinko balls into the variable winning ball device. Therefore, in order to satisfy the repeat continuation condition, there is no need to perform any special ball-hitting operation other than the ball-hitting operation aimed at the variable winning ball device, and the player can easily concentrate on the game. . Moreover, even after the reciprocating operation of the variable winning ball device ends, the repeating condition detecting means maintains the detectable state, so that the repeating condition is immediately set after the variable winning ball device ends in a state advantageous to the player. Even when the condition is satisfied, the repeat continuation control is performed, and it is possible to prevent troubles occurring after the repeat continuation condition is satisfied, which is the end of the advantageous state of the variable winning ball device.

The balls received by the ball receiving plate 341 are guided to the back side through a hole that becomes the winning area 3a. Furthermore, passage areas 342 and 343 for allowing balls to pass are formed in the horizontally 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. A suitable number of obstruction nails 35 are installed in a horizontal row at approximately the center of the mounting plate 31 and above the opening 32. A guide member 36 is provided between the obstacle nail 35 and the opening 32.
is installed. The guide member 36 has guide plates extending in the vertical direction at multiple locations in the lateral direction,
It works by guiding the ball vertically and causing it to fall.

The variable prize winning ball device 40 opens the opening/closing plate 41 forward in a first state that is advantageous to the player to easily receive balls, and in a second state that is disadvantageous to the player, the opening/closing plate 41 opens and closes. The plate 41 is closed and balls cannot be received. 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). On both side edges of the opening/closing plate 41, there are triangular side walls 411, 41 protruding toward the back side.

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 is horizontally divided into a plurality of winning areas 43a to 43c. Among the winning areas divided in this way, winning area 43a
is a so-called specific area in which conditions are set such that the variable winning ball device 40 can be placed in a state where it is easy to win by opening the opening/closing plate 41 again with a winning ball while the opening/closing plate 41 is open in a specific gaming state. ing. The winning areas 43b and 43c other than the specific area 43a become normal areas. in this way,
A feature of this embodiment is that at least one of the plurality of winning areas of the variable winning ball device 40 is formed in a specific area. By forming the specific area 43a 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, even after the hit ball enters the variable winning device 40, depending on the flowing state of the winning ball, it may fall into the specific area 43a or fall into the normal areas 43b, 43c. Sometimes,
Depending on the area in which the ball falls, the variable winning ball device is repeatedly controlled to the first state again, and the player loses interest even after the ball hits the variable winning ball device. This will further enhance the interest of the game.

A detection switch 44a is provided in relation to a winning area 43a which is a specific area. The detection switch 44a is for detecting a winning ball in the winning area 43a. The output of this detection switch 44a is applied to the drive control means as a repetitive condition detection output as described later, and the variable winning ball device 40
is repeatedly controlled. In other words, this detection switch 44a is a repetition condition detection means for detecting a repetition continuation condition determined so that the variable winning ball device can be repeatedly changed to the first state based on the winning balls that have entered the specific area. is configured. Further, the winning balls in the winning areas 43a to 43c are guided downward via paths 421 and 422, respectively. Below the paths 421 and 422,
A detection switch 44b for detecting a winning ball in the winning area 43 is provided. 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
The structure includes a T-shaped lever 453, a rod 455, and a spring 456. T-shaped lever 453
is rotatably attached to the mounting plate 31 by a pin 454 at its center. T-shaped lever 453
One end of the short side is the plunger 4 of the solenoid 451.
52, and a spring 456 is connected to the lever 453 and the other end of the short side. Further, one end of a rod 455 is engaged with the long side end of the T-shaped lever 453, and the other end of the rod 455 is connected to the opening/closing plate 4.
1 by a pin 413.
When the solenoid 451 is electrically deenergized, the other short end of the T-shaped lever 453 is connected to the spring 45.
6, the tip of the long side of the lever 453 is pulled down, and the rod 453 is pulled down.
55 applies a downward force to the side wall of the opening/closing plate 41, and the opening/closing plate 41 is brought into a closed state. Conversely, when solenoid 451 is electrically energized,
The T-shaped lever 453 is rotated clockwise (clockwise in FIG. 4A), the rod 455 is pulled upward, and the opening/closing plate 41 is opened forward.

In addition, in this embodiment, the variable winning ball device 40
In the first state, which is advantageous for the player, the opening/closing board 41 is in an open state where it is easy for balls to win, and in the second state, which is disadvantageous for the player, the opening/closing board 41 is in a closed state. explained what was in a condition that made it impossible to win. 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-described embodiments, and can take various structures and states. For example, as another example of a variable winning ball device, like a so-called chulip, in the first state that is advantageous for the player, a pair of ball receiving pieces are opened on the left and right, and the ball is easy to win. However, 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/closable, and a ball socket capable of receiving one ball provided on the top of the opening/closing plate, and a second In the state, the opening/closing plate is closed,
This is a state in which balls can only be won through the ball entrance provided at the top of the opening/closing board, and winning balls occur with a low probability.In the first state, the opening/closing board is open and a winning ball is created with a high probability. You can also do that.

Therefore, AND gate 632 derives a clock pulse according to the set output of flip-flop 631 and supplies it to ring counter 634. ring counter 634
, which 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 counting location is determined by the determination included in the decoder driver 635 and the specific game state detection circuit 64. is applied to 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 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, the rotating drums 51a to 51c
In the state in which the segment displays 50B and 50B are variably displayed, the player stops at an arbitrary timing in the hope that the combination of display states of the rotating drums 51a to 51c in each row will result in a specific gaming state. Press the command switch 17. Note that the stop command switch 17 is activated within a certain period of time set by the timer 622 after the variable display starts.
If is not pressed, the output of the timer 622 issues a stop command. 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),
Accordingly, the claw-like portions 582 of the locking levers 58a to 58c
The corresponding ratchet gears 52a to 52c are respectively engaged, and the rotating drums 51a to 51c are sequentially stopped. Further, 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
It is given to the display state determination circuit 643 as a determination command signal. Resetting flip-flop 631 causes AND gate 632 to stop deriving clock pulses. Therefore, the ring counter 63
The count value of 4 stops incrementing, and accordingly, the number corresponding to the count value counted by the ring counter 634 is 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, 642 are provided facing each other on both axially outer sides of the rotating drum. Although not shown in FIG. 5, on each side surface of the rotating drums 51a to 51c, a rotating drum is provided concentrically on a first circumference and a second circumference 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 in . Four types of identification information are output depending on the stopped state of each of the rotating drums 51a to 51c. For example, if the part on the first and second circumferences where a through hole is drilled is set to logic "1", and the part where no through hole is drilled is set to logic "0", then there are four types. 2-bit codes "00", "01", "10", and "11" 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 a score based on the combination of identification information displayed on the rotating drums 51a 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 a combination of a specific game state,
In other words, unless the combination is determined to give the maximum value (for example, all A symbols),
The display state 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 judgment signal j2 to j4 corresponds to a corresponding timer 72.
~74 is given. Each timer 72, 73, 74
These derive high-level signals for predetermined fixed times t2, t3, and t4 in response to input of corresponding determination signals j2, j3, and j4, respectively. Here, the fixed time set by the timers 72 to 74 is selected such that t2≧t3≧4t, for example, t2=10
seconds, t3 = 6 seconds, t4 = 4 seconds. Note that the determination circuit 645 determines that the determination signal is other than j1 (that is, j2
~ j4), no determination of the display state of the segment display 50b is made.

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 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, the ball hit into the winning areas 43a to 43
When a prize is won in any one of c, the prize ball discharging mechanism pays out a predetermined number of prize balls according to the winning ball. In this case, even if the ball hits the winning area 43a, 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 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, which is applied to the determination circuit 645 and as a set input to the flip-flop 761. Accordingly, flip-flop 7
61 is set. Further, the determination circuit 645
In response to the determination signal j1, it is determined 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 by the combination setting section 644 should be given. At this time,
Even if the combination of display states of the rotary drums 51a to 51c gives the maximum value, if the segment display 50B does not display the number 7, the determination circuit 645 outputs the maximum value provision command signal j0 (high level). signals). In this case, the flip-flop 76 set by the judgment signal j1
A set output of 1 is provided to timer 763 via OR gate 762. In response, timer 763 starts counting a certain period of time t1, derives a high level signal during that period, and the high level signal is applied to the connector of transistor 764. At this time, the mismatch output (low level) of the comparator circuit 653 is inverted to high level by an inverter 655 and is applied to the base of the transistor 764. Therefore, transistor 764 is connected to comparator circuit 65.
3 is conductive during the period when timer 763 is outputting a non-coincidence 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, flip-flop 766
is not set, and gate 651
and 767 remain disabled. Therefore, the predetermined number of winning balls detection circuit 65 detects the number of winning balls in the winning area 43a.
A winning ball is not detected and a preparation operation for repeatedly opening the variable winning ball device 40 is not performed.
Then, when the timer 763 measures a certain period of time t1, its output becomes low level, so the opening/closing plate 4
1 is closed.

Next, when a specific game state, which is a feature of this embodiment, occurs, that is, the rotating drums 51a to 51c
A predetermined state in which a combination of display states 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 described.

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, the AND gate 646
Since the low level of the output of the predetermined value imparting state detection circuit 66 is inverted to the high level, a high level determination signal j0 is derived from the AND gate 646. Decision signal j0 sets flip-flop 766. Therefore, when a specific gaming state is entered, only the display state of the rotating drums 51a to 51c described above is performed in accordance with the predetermined signal j1, and the operation is performed when the maximum value giving state is reached, and the repetition based on the specific gaming state is performed. A value adding operation is performed. That is, the timer 763 derives a high level for a predetermined time t1 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 651 is enabled by the set output of flip-flop 766. Therefore, the hit ball falls into the winning areas 43a to 4.
If you win in any of 3c, the detection switch 44
b. The detection output of the detection switch 44b is sent to the counter 6 via an AND gate 651.
52. The counter 652 calculates the number of winning balls in the winning areas 43a to 43c in a specific gaming state, and provides the calculated 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 won into the variable winning ball device 40 in the specific gaming state set by the setting section 654. The comparison circuit 653 is a counter 654
When the calculated value of is smaller than the set number, a low level signal is derived. 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 calculated value of the counter 652 is displayed on the numerical information display 6 by the numerical information display drive circuit 67. The player looks at the display state of the numerical information display 6 and selects the variable winning ball device 4 in a specific game state.
It is possible to know the number of winning balls during the opening period of 0, and also easily know how many winning balls are allowed. Therefore, there is an advantage that the player can easily formulate a strategy for the game based on this display.

If a predetermined number of winning balls are received before the timer 763 times up, the comparison circuit 6
53 derives a high level signal. This high level signal is inverted to a low level signal by inverter 655, 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 winning balls in the winning area reaches a predetermined number before the fixed time t1 set by the timer 763 has elapsed,
The solenoid 451 is forcibly deenergized and the opening/closing plate 41 is closed. At this time, inverter 6
The output of 55 is applied to a falling differentiation circuit 767 via an OR gate 765, and is differentiated into falling. And this differential pulse is a monostable multi-76
8, and the monostable multi 768 outputs a high level signal for a certain period of time. The output is applied to AND gates 769 and 76a, and causes flip-flop 761 to be set.

By the way, after the specific game state, the variable winning ball device 4
When a ball enters the winning area 43a during the period in which the 0 is being driven open, the detection switch 44a outputs a detection output to set the flip-flop 76b. For this reason, and gate 769
This means that there is a set output from the flip-flop 766 (that is, it is in a specific gaming state), that there is a set output from the flip-flop 76b (that is, that a condition that allows the variable winning ball device 40 to be repeatedly opened is detected), and that the monostable multiplayer 768
(i.e., the variable winning ball device 40
A high-level signal is derived based on the above-mentioned results (developed by the above), and the high-level signal is applied to the timer 63 via an OR gate 762. Timer 76
3 starts counting operation for a certain period of time t1 again and derives a high level signal during that period. This high level signal is transmitted to the transistor 764 and the OR gate 71.
is applied to the driver 75 via the solenoid 4.
51 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. and,
The detection switch 44a constitutes a repetition condition detection means that detects a repetition continuation condition determined so that the variable winning ball device can be repeatedly changed to the first state based on the winning balls that have entered the specific area. has been done. It should be noted that this repetition condition detection means and the specific gaming state detection means may be used in combination.

Note that after a certain period of time delay from the output of the monostable multi 768, the delay circuit 76c outputs the flip-flop 76.
b. 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 multi 768 is no longer given as the other input of the AND gate 76a, so the AND gate 76a receives a high level signal. do not derive.

After that, in the same way, after a specific gaming state, for a certain period of time
One cycle is defined as t1 (for example, 30 seconds) or until a predetermined number (for example, 10) of winning balls are generated during one opening period, and as long as there are winning balls in the winning area 43a, that cycle continues. repeated. Therefore, the pachinko gaming machine 1 is limited in the number of prize balls to be paid out once it enters a specific gaming state.
0, the number of winning balls during one opening period of the variable winning ball device 40 is limited to a predetermined number or less, and the number of repeated openings can be increased,
This has advantages such as being able to maintain an advantageous state for a long time for the player and enlivening the atmosphere of the game. Note that the above-mentioned repetitive control may be performed immediately upon receiving the detection output of the detection switch 44a, without waiting for the end of the opening control currently being performed. Alternatively, the repetitive control may be started only when there is a detection output from the detection switch 44a and the display mode of the variable display device at the time of the output is a predetermined one.

Note that when the variable winning ball device 40 is repeatedly driven to open, if no ball enters the winning area 43a, the flip-flop 76b
remains reset. Therefore, in this case, the AND gate 76a derives a high level signal in response to the output of the monostable multiplier 768, and resets the flip-flop 766 via the OR gate 76d. As a result, the repeated opening and driving operation of the variable winning ball device 40 is ended.

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 award state detection circuit 66 detects that a predetermined number of prize balls (for example, 2000 pieces) have been paid out, the detection output is given to the flip-flop 766 via the OR gate 76d. will be 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 certain number of prize balls are paid out, but the variable winning ball device 40
The system is configured to detect the number of repeated openings, and when the number reaches a certain number (for example, 10 times), to derive a detection output from the predetermined value pairing state detection circuit 66, thereby making the service uniform. Good too.

Further, in the above-described embodiment, the variable winning ball device 4 is used as a repeating condition detecting means in a specific game state.
During the opening period of 0, the number of winning balls in the winning area 43a is 1.
Although the case where there are more than 10 repetition conditions has been described, other repetition conditions may be detected. For example, the number of balls won 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 such that the repetition condition is detected when the number of times the number of times is greater than or equal to 1). In that case, counter 65
It is sufficient to separately provide a comparison circuit for detecting that 2 has counted the small number of winning balls (3), and to set the flip-flop 76b with the output of the comparison circuit.

Furthermore, in the above embodiment, the specific gaming state is determined based on the combination of the displays on the rotating drum display mechanism 50A and the segment display 50B. A specific gaming state may be determined. 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, and the pachinko gaming machine can improve the service provided to the 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 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 above, a case was shown in which a hardware circuit was used to explain the operation of the present invention, but the technical idea of the present invention is to perform program processing using a microprocessor. It can also be done by. In this case, the program can be set to perform the circuit operations shown in Figures 6 and 7, but such program settings can be easily devised by a person skilled in the art who is familiar with electronic technology. Explanation will be omitted.

[Effects of the Invention] The present invention having the above configuration allows the player to fully utilize the advantageous state of the variable prize winning ball device without overlooking it, and also allows the player to fully utilize the advantageous state during the period when the variable winning ball device is switched to the advantageous state. It is possible to prevent the monotony of the game, and to give the player a sufficient sense of satisfaction by adopting repeated continuation control, while also allowing the player to concentrate on the game, and to prevent the game from becoming repetitive after the continuation condition is satisfied. To provide a pachinko game machine which can prevent troubles related to this, give a great sense of satisfaction to the player during the game as a whole, and eliminate the dissatisfaction of the player during the game as much as possible.
