Description

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

[Prior Art] For this type of pachinko game machine, some of the commonly known ones include, for example,
- There is a device described in Publication No. 78975, in which when a pachinko ball enters a special winning hole and the gaming state becomes a predetermined specific gaming state, the first state and the second state of the variable winning ball device The variable winning ball is continuously driven back and forth repeatedly, and then when either a certain period of time passes or a certain number of pachinko balls enter the variable winning ball device, whichever comes first, the variable winning ball device wins the variable winning ball. It was configured to stop the repetitive reciprocating drive of the ball device. In this conventional pachinko game machine, the repetitive reciprocating drive of the variable winning ball device is controlled to stop after at least a certain period of time has elapsed, so the player can make the most effective use of the allowed certain period of time. It is necessary to cause as many balls as possible to enter the variable winning ball device within a certain number of balls that are allowed to win. Therefore, the player can quickly notice that the specific game state has been established and the change of the variable winning ball device has started, and the player can operate the ball to hit the ball aiming at the variable winning ball device from the beginning of the change. In order to achieve this, in this conventional pachinko game machine, the variable winning ball device is repeatedly driven back and forth between the first state and the second state, and the reciprocating movement of the variable winning ball device allows the player to quickly identify the ball. It was configured to notify that a gaming state has occurred.

[Problems to be Solved by the Invention] On the other hand, from the player's perspective, during the period of repeated reciprocating movement between the first state and the second state of the variable winning ball device, the player can play as many pachinko balls as possible within the allowable range. Since the player has a desire to win a pachinko ball, he attempts to estimate when the repeated reciprocating movement of the variable winning ball device will end, and counts the current number of winning pachinko balls to determine if the winning ball is still acceptable. An attempt is made to calculate the number of winning pachinko balls.
However, in this type of conventional pinball game machine, two conditions are involved in the stopping conditions for the repetitive reciprocating drive of the variable winning ball device: the elapse of a predetermined period of time and the winning of a certain number of pachinko balls. It is extremely difficult for the player to predict whether the above-mentioned stopping conditions will be met, and furthermore, the calculation of the number of winning pachinko balls is complicated and prone to errors, resulting in players making incorrect gaming strategies. This will cause inconvenience. In addition, the calculation of the winning number of pachinko balls is as follows:
It is necessary to calculate the number of pachinko balls that have won into a variable winning ball device that repeatedly moves back and forth between the first state and the second state, and the variable winning ball device repeatedly moves back and forth between the first state and the second state. Because of this, it is often difficult to judge whether or not a hit ball has won a prize, which makes it even more difficult to visually estimate whether the conditions for stopping the repetitive reciprocating drive are met. Moreover, stopping the repetitive reciprocating drive of the variable winning ball device is a disadvantageous situation for the player, and due to a misunderstanding of the stopping conditions, the variable winning ball device repeatedly reciprocates against the player's will. If the drive is stopped, the player will feel psychologically very dissatisfied, and there is a risk of frequent troubles with employees over the number of prizes won. especially,
The number of winning pachinko balls in the variable winning ball device is
1 of the conditions for stopping the repetitive reciprocating drive of the variable winning ball device
However, if the variable winning ball device switches to a disadvantageous state against the player's will due to a miscalculation of the conditions, the player will be particularly dissatisfied, and this will cause great dissatisfaction. There was also a risk that the original function of the pachinko game machine, which aims to provide players with entertainment, would be completely impaired.

In view of the above-mentioned circumstances, the present invention makes it easy to estimate whether the conditions for stopping the repeated reciprocating drive of the variable winning ball device are satisfied, makes it easier for players to formulate the correct game strategy, and avoids troubles related to the number of winning balls. To provide a pachinko game machine that does not impair the interest of the game.

[Means for Solving the Problems] A pachinko game machine according to the present invention is arranged on a game board, and has two states: a first state that is advantageous to the player, and a second state that is disadvantageous to the player. A variable winning ball device whose state can be freely changed, and a specific gaming state detection means for detecting that the pachinko gaming state has become a predetermined state such that the variable winning ball device can be changed within a predetermined period of time. , Winning ball detection means for detecting a winning ball that has entered the variable winning ball device when the variable winning ball device is in the first state; Winning possible to the variable winning ball device when the variable winning ball device is in the first state. a number of winning balls setting means for setting the number of winning balls; a number of winning balls set by the entered prize ball detection means; The number of winning balls reaches the set number;
or determining means for determining that the certain period of time has elapsed without the number of winning balls reaching the set number; The reciprocating motion with the state No. 2 is continuously repeated a plurality of times, the repeated reciprocating motion is maintained until the output of the determining means is derived, and the variable winning ball device is driven in response to the output of the determining means. The present invention is characterized in that it includes a drive control means for stopping the repetitive reciprocating drive, and further includes a numerical information display means for displaying the number of winning balls in response to the output of the winning ball detecting means.

[Function] According to the present invention, when the gaming state becomes a predetermined specific gaming state, the variable winning ball device is continuously and repeatedly driven to reciprocate between the first state and the second state. The number of winning balls that can be won in the variable winning ball device is set in advance by the number of winning balls setting means, and if the number of winning balls reaches the number set by the number of winning balls setting means within a certain period, or When the certain period of time passes without the number of balls reaching the set number, the repetitive reciprocating drive of the variable winning ball device is stopped. Furthermore, in order to display the number of winning balls that have won in the variable winning ball device in the first state and notify the player by displaying the numerical information display means, the timing for stopping the repetitive reciprocating drive of the variable winning ball device is determined. This makes it easier to estimate the number of winnings, and also avoids troubles regarding the number of prizes won.

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

The player takes the ball borrowed from the ball rental machine to 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 the press of the ball hitting switch 14s, the motor 241
Electric power is supplied to the motor 241, which rotates the motor 241.
By intermittently rotating the ball hitting hammer 243, balls are driven into the game board 1 one by one. When the player is playing the ball hitting game in this way, if the ball hits one of the safe holes 2a to 2c or the Yakumono 4a or 4b, the prize ball release mechanism is activated and one winning ball is released. The release of a predetermined number of prize balls is controlled.

Furthermore, when the ball hits one of the winning areas 3a to 3c, the corresponding detection switch 22a or 22b derives a high level signal, and the signal is given to the drive circuit 621 via the OR gate 611. , is applied to timer 622. Further, the high level signal from the OR gate 611 is applied to a flip-flop 63 included in the display drive circuit 63.
1 to set the flip-flop 631. The drive circuit 621 operates the solenoids 57a to 57c based on the signal from the OR gate 611.
The claw-like portions 5 of the locking levers 58a to 58c
82 and the corresponding ratchet gears 52a to 52c are released from engagement, and at the same time, the motor 56 is driven to rotate. As a result, the rotating drums 51 of each row
a to 51c are driven to rotate, and the display state of the rotating drum is varied. Also, flip-flop 631
The set output of 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, 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 63
4 cyclically counts 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 determined by the decoder driver 635 and an example of the specific game state detection means. It is applied to a determination circuit 645 included in the game state detection circuit 64. Decoder driver 635
decodes the count value of the ring counter 634 and displays the segment display 50 based on the count value.
The numbers displayed at B are sequentially changed in synchronization with the period 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 is
The flip-flop 631 is reset and the display state determination circuit 643 is output as a determination command signal.
given to. Resetting flip-flop 631 causes AND gate 632 to stop deriving clock pulses. For this reason, the ring counter 6
The count value of 34 stops incrementing, and therefore, 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 51d is a combination of a specific gaming 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 determination signal j2-j4 is given to a corresponding timer 72-74. Each timer 72, 73,
74 are the corresponding judgment signals j2, j3, j
4, a predetermined period of time t2,
High level signals are derived only at t3 and t4. Here, the fixed times set by the timers 72 to 74 are selected so that t2≧t3≧t4, and for example, t=10 seconds, t3=6 seconds, and t4=4 seconds.
Note that the determination circuit 645 does not determine the display state of the segment display 50B if the determination signal is other than j1 (ie, j2 to j4).

For example, assuming that the display state determination circuit 643 derives the determination signal j2, the timer 7
2 derives a high level signal for a certain period of time t2.
This high level signal is applied to AND gate 799 via OR gate 71, and a pulse signal is applied to driver 75. In response, the driver 75 intermittently 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 and closed for a certain period of time t2 to facilitate the winning of balls. At this time, the ball hit is in the winning area 43
When a prize is won in any one of a to 43c, a 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 uses the determination signal j1
The signal j1 is applied to the determination circuit 645 and as a set input to the flip-flop 761. In this way, flip-flop 761 is set. In addition, the determination circuit 64
5 is a ring counter 63 according to the determination signal j1.
The count value of 4 is the display state where the maximum value set in the combination setting section 644 should be given (for example, 7
is displayed). At this time, the determination circuit 645 determines whether the rotating drums 51a~
Even if the combination of display states 51c gives the maximum value, unless the segment display 50B displays the number 7, the maximum value giving command signal j0 (high level signal) is not derived. In this case, the set output of flip-flop 761 set by determination signal j1 is output to OR gate 762.
is given to timer 763 via. In response, 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 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
is conductive during the period when the comparison circuit 653 is deriving the mismatch output, and the output of the timer 763 is connected to the OR gate 7.
1 to the AND gate 799 and a pulse signal to the driver 75. In response, the driver 75 intermittently energizes the solenoid 451 to open and close 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,
Preparatory operations for repeatedly and continuously opening and closing the variable winning ball device 40 are not performed. And timer 763
When the constant time t1 is counted, the 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, 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 64
6 is given by inverting the low level of the output of the predetermined value provision state detection circuit 66 to a high level, so that 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 response to the determination signal j1, and the operation is performed when the display state of the rotating drums 51a to 51c becomes the maximum value giving state, and the repetition based on the specific gaming state is A value adding operation is performed. That is, the timer 63 derives a high level for a certain period of time t1 from when the determination signal j1 is applied, drives the driver 75, and opens the opening/closing plate 41. At this time, and gate 65
1 is enabled by the set output of flip-flop 766. Therefore, when the ball hits either of the winning areas 43a, 43c, it is detected by the detection switch 44b. The detection output of the detection switch 44b is applied to a counter 652 via an AND gate 651. counter 65
2 is the winning area 43a to 4 in a specific gaming state.
The number of winning balls in 3c is counted, and the counted value is given to a comparison circuit 653 and a numerical information display drive circuit 67. The comparison circuit 653 is given as a reference input the number of winning balls (for example, 10) that can be won into the variable winning ball device 40 in a specific gaming state, which is set in a setting section 654 of an example of the winning ball number setting means. . Comparison circuit 653 derives a low level signal when the count value of counter 652 is smaller than a set number. This low level signal is applied to the inverter 655
Since the signal is inverted to a high level and provided as the base input of the transistor 764, the transistor 764 provides the 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 by the numerical information display drive circuit 67 on the digital numerical information display 6 shown in FIG. This numerical information display device 6 is constituted by a number of light emitting diodes corresponding to the number of winnings that can be set by the setting section 654, and uses a well-known light emitting diode type display means that lights up one by one for each winning ball hit. may be configured. By looking at the display state of the numerical information display 6, the player can know the number of winning balls during the opening/closing period of the variable winning ball device 40 in a specific gaming state, and how many winning balls are allowed. You can also easily tell if there are any. Therefore, there is an advantage that the player can accurately and 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 signal 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 of the opening/closing plate 41 is stopped. Then, by the predetermined number of winning balls detection circuit 65 and opening/closing drive circuit 76,
A determining means is configured to determine that the number of winning balls has reached the set number within a certain period of time, or that the certain period of time has elapsed without the number of winning balls reaching the set number. The judgment output of this judgment means is given to the drive control circuit 70. Further, when the opening/closing plate 41 is closed, the inverter 655
The output is given 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. This output is applied to AND gates 769 and 76a and causes flip-flop 761 to be reset.

By the way, after the specific game state, the variable winning ball device 4
When a ball enters the winning area 43a while the 0 is being driven open, the detection switch 44 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), and 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 opened and closed repeatedly and continuously is detected). ) and the existence of the output of the monostable multi 768 (that is, the opening of the variable winning ball device 40), a high level signal is derived and the high level signal is given to the timer 763 via the 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 given to the driver 75 via the transistor 764 and the OR gate 71.
Solenoid 451 is energized. Therefore, after entering the specific gaming state, the variable winning ball device 40 is repeatedly driven to open and close as long as the repeating condition is detected.

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/closing period, and as long as there are winning balls in the winning area 43a, that cycle continues. repeated.

In addition, when the variable winning ball device 40 is repeatedly and continuously driven to open and close, the balls are not in the winning area 43.
If there is no prize in a, flip-flop 7
6b remains reset. Therefore, in this case, the AND gate 76a derives a high level signal according to the output of the monostable multi 768, and the high level signal is output from the flip-flop 766 via the OR gate 76d.
to reset. 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 40 is continued. However, if the predetermined value awarding state detection circuit 66 detects that a predetermined number (stopped number) of prize balls (for example, 2000) has been paid out, the detection output is
6d to flip-flop 766, and flip-flop 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, The configuration may be such that the number of times the opening/closing drive is repeated is counted, and the detection output is derived when the number of times reaches a certain number, for example, 10 times.

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/closing 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 repeat continuation condition is detected when the number of times (number) or more occurs. 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.

[Effects of the Invention] As described above, according to the present invention, changes in the variable winning ball device based on the establishment of a specific gaming state can be realized by reciprocating the variable winning ball device between the first state and the second state. In the pachinko game machine, the variable winning ball device is repeatedly driven back and forth in the pachinko game machine, which allows the player to quickly notice the change in the variable winning ball device and perform ball hitting operations that effectively utilize the establishment of the specific game state from the beginning of the change in the variable winning ball device. In order for the player to know by displaying the number of winning pachinko balls in the slot, the conditions for stopping the repeated reciprocating drive of the variable winning ball device are based on two factors: the elapse of a certain period of time and the predetermined number of winning balls. Despite this structure, it is easy to estimate when the stopping condition will be met, allowing the player to correctly and easily formulate a gaming strategy, and also avoiding troubles regarding the number of prizes won. Overall, we have been able to provide a pinball game machine that can improve the enjoyment of the game.
