Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pachinko game machine, and specifically includes a game board in which a winning area is formed and a ball firing mechanism that fires pachinko balls onto the game board. Regarding pachinko gaming machines.

[Prior Art] This type of pachinko gaming machine has been generally known in the past, including, for example, a first state that is advantageous to the player and a second state that is disadvantageous to the player. There was one in which a variable winning ball device that could change its state was placed on the game board. and,
When the pachinko game state becomes a specific game state, the variable winning ball device is changed to the first state for a certain period of time. Further, in conventional pachinko gaming machines, an interruption condition detection means is provided, and the game is interrupted by stopping the ball firing mechanism from ejecting pachinko balls based on the detection output from the interruption condition detection means. . This interruption condition detection means is used to detect urgent matters of the player such as making a phone call or moving a car, etc.
It is possible to temporarily suspend the game in the event of an emergency such as the occurrence of a ball jam, the transfer of prize balls from a full prize ball tray to another container, or the need to purchase and replenish more balls. It was set up for.

[Problems to be Solved by the Invention] However, in this type of conventional pachinko gaming machine, if the game is interrupted by the interruption condition detection means during the period in which the variable winning ball device is changing to the first state, In this case, the variable winning ball device was not interrupted until the period of the first state had elapsed, so the period of the first state elapsed while the game was interrupted, and when the game was restarted, the variable winning ball device In some cases, the first state of the winning ball device has mostly ended or it has already changed to the second state, causing the player to suffer an unexpected disadvantage. Therefore, even if an emergency situation occurs during which the game should be interrupted during the first state of the variable prize winning ball device, the player does not try to stop firing pachinko balls to avoid disadvantage,
There was also a risk that the progress of the game would be hindered, such as the prize balls overflowing or the balls becoming jammed further.

In view of the above circumstances, the present invention aims to provide a pachinko game machine that does not cause any disadvantage to the player even if the game is interrupted during the first state of the variable winning ball device. .

[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 that can freely change its state; and a pachinko game state in which the variable winning ball device is
a specific gaming state detection means for detecting that a specific gaming state has been reached, which is determined to be able to change to a state in which the pachinko ball can be changed, and an interruption condition that causes the ball firing mechanism to stop firing pachinko balls and interrupt the game. an interruption condition detection means for detecting that the variable winning ball device has changed to the first state, and during the measurement, the interruption condition detection means detects that the interruption condition is met; a period measuring means that stops measuring the period in response to a change in the period; and a period measuring means that puts the variable winning ball device into a first state in response to a detection output from the specific gaming state detecting means, and the period measuring means stops measuring the period in advance. The first variable winning ball device
and a drive control means for controlling the drive to end the state and enter the second state.

[Operation] When the pachinko game state becomes a specific game state, the variable winning ball device is driven and controlled to the first state, and the period of change of the first state of the variable winning ball device is measured by the function of the period measuring means. Ru. During measurement by the period measuring means, if the interruption condition detecting means detects that the interruption condition is met, the period measuring means stops measuring the period. Then, if this period measuring means measures a predetermined period, the variable winning ball device
The drive is controlled to the following state.

In other words, if the game is interrupted during the period in which the variable winning ball device is in the first state, the measurement of the period in which the variable winning ball device is in the first state during the interruption is also stopped. There is no inconvenience that the first state of the variable winning ball device cannot be fully utilized.

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

FIG. 1 is a front view of a pachinko game machine according to an embodiment of the present invention. In the configuration, the pachinko game machine 10 has a front frame 11 mounted so as to be freely openable and closable, and a game board 1 mounted on the front frame 11 so as to be freely attachable and detachable. The game board 1 has safe holes 2a to 2, which are examples of winning areas.
c. winning areas 3a to 3c with defined conditions for changing the variable display device 40 (described later) depending on the prize balls;
Multiple Yakumono (commonly known as Chulip) 4a, 4
b, and an out ball inlet 5 are formed.

Further, in the lower part of the game board 1, a variable prize winning ball device (so-called electric type Yakumono) 30, which will be explained in detail with reference to FIG. 3 described later, is arranged. This variable winning ball device 30 includes light emitting diodes 6a,
6b is associated. light emitting diode 6
a and 6b, when the variable winning ball device 30 is in a first state advantageous to the player in a specific game state, the player receives a reward after a certain period of time based on the number of balls passing into a predetermined winning area or passing area. This is used to indicate that a predetermined condition has been met so that the second state, which is disadvantageous, can be returned to the first state again.

A variable display device 40, which will be described in detail with reference to FIGS. 4 and 5, is provided approximately in the center of the game board 1. This variable display device 40 includes:
A plurality of light emitting diodes 7a-7d are provided in association. The light emitting diodes 7a to 7d are used to display the number of times the variable display device 40 can perform variable display depending on the number of light emitting displays. As a means for displaying the number of times the variable display device 40 can be variably displayed, a segment display capable of displaying numbers may be used instead of the light emitting diodes 7a to 7d. In this case, the segment display may also be used as the segment display 41, which will be described later, or may be provided separately.

Further, at the upper corner of the game board 1, a segment display 8 is provided for displaying a numerical value membrane. This segment display 8 is used to display the elapsed time in the first state or the remaining time that can be in the first state when the variable winning ball device 30 enters the first state. Here, the reason why the variable winning ball device 30 displays the elapsed time in the first state or the remaining time that can maintain the first state is that when the player interrupts the game, it stops counting the time. This is to let players know that they are doing everything they can to avoid putting them at a disadvantage, and to make it easier for them to plan their gaming strategies. Specific means in this case will be explained in detail later.

Below the front frame 11 is a prize ball payout opening 1.

Further, a speaker 17a and a stop command switch 18 are provided on the front frame 11 as necessary. The speaker 17a is used to notify the player of a specific game state by voice. Note that the speaker arrangement position is not limited to the front frame 11, but also a part of the curtain plate (1
7b) may be selected. The stop command switch 18 is used to command the variable display of the variable display device 40 to stop by operation by the player. Note that the stop command switch 18 is 1 in the illustration.
Although a case in which one is provided is shown, a plurality of such devices may be provided corresponding to each of the rotating drums included in the variable display device 40.

2A and 2B are illustrative views of the back structure of the pachinko game machine, and in particular, FIG. 2A shows the game board 1.
2B shows a mechanism plate attached to the back side of the front frame 11 so as to be openable and closable. Next, the back structure of the pachinko gaming machine 10 will be specifically explained.

Game board 1 in which the safe holes 2a to 2c are formed
Paths 211 and 212 for guiding the prize balls to the Yakumono 4a and 4b are formed on the back side. Detection switches 22a to 22c are provided on the back surfaces of the winning areas 3a to 3c, respectively. These detection switches 22a to 22c are located in the winning area 3a.
By detecting the prize balls to 3c, it is used to detect the conditions under which the variable display device 40 can be variably displayed. At a position slightly above the out ball entrance 5 on the back side of the game board 1, there is a path 213,
214 is provided. This route 213, 214
are safe holes 2a to 2c, winning areas 3a to 3c,
The winning balls that have been won into either the Yakumono 4a, 4b or the variable winning ball device 30 are guided to the winning ball processing device 23. The winning ball processor 23 is connected to the path 21
Prize balls guided through 3 are intermittently dropped one by one. When the winning balls dropped by the winning ball processing device 23 pass through the meandering path 215, the weight of the balls actuates the operating lever 261 connected to the prize ball payout mechanism 26, and one winning ball is released. The ball is used to perform one prize ball payout operation. In addition, when an electric type is used as the prize ball payout mechanism, a winning ball detection switch (not shown) that is closed in conjunction with the rotation of the winning ball processing device 23 is provided. and,
The prize ball payout mechanism is electrically driven by the output of the winning ball detection switch to pay out a predetermined number of prize balls.

Front frame 11 corresponding to the location of the ball-hitting handle
An electric ball hitting mechanism 24, which is an example of a ball firing mechanism, is provided on the back side of the ball. This electric ball hitting mechanism 24 is
As is well known in the art, a ball hitting cam 242 is rotated by the rotational force of a motor 241, and a ball hitting hammer 243 is intermittently rotated by the rotation of the ball hitting cam 242 to hit a ball. In this manner, when the ball firing mechanism is an electric ball hitting mechanism, the ball hitting command switch 14s is used as means for detecting the ball firing operating state (that is, the ball hitting operating state). In this embodiment, if the batted ball command switch is not pressed or closed during the period when the variable winning ball device 30 is opened in the specific game state,
The timing operation for a predetermined period of time is stopped so that the variable winning ball device 30 can be opened.

In addition, as another example of the ball firing mechanism, a conventionally well-known manual ball hitting mechanism may be used, in which the ball hitting handle is manually rotated intermittently to hit the ball. In this case, the ball firing operation state detection means may be one that detects that the ball-striking handle has been rotated at least once in a short period of time (for example, one minute), or one that detects that the ball-striking handle has been rotated at least once in a short period of time (for example, one minute), or one that detects that the ball-striking handle is rotated at least once in a short period of time (for example, one minute), or one that detects that the ball-striking handle is rotated at least once in a short period of time (for example, one minute), or one that detects that the ball-striking handle is rotated at least once in a short period of time (for example, one minute). A device that is connected to a touch switch connected to the ball and detects that the touch switch has been operated for a short period of time, or a device that is provided near the ball-striking handle and that is used to secure the hand when flicking the ball-striking handle with the thumb. A touch switch or the like is used that detects when a finger touches a protruding member (so-called proboscis).

Another ball firing mechanism is a ball firing mechanism that is equipped with a lift that lifts the pachinko balls from the end of the prize ball tray to the top of the game board, and that allows the direction in which the pachinko balls are fired from the top of the game board to be freely selectable. mechanism, for example, the Japanese Patent Application Laid-Open No. 1983-1987, which the present applicant proposed earlier.
-36984 may be used.

A prize ball tank 27 is fixed to the upper part of the mechanism plate 25. Replenishment balls are supplied to the prize ball tank 27 from a supply gutter (not shown). Prize ball tank 2
A prize ball payout mechanism 26 is formed below 7. Between the prize ball payout mechanism 26 and the prize ball tank 27, an alignment path 271 is provided at an angle.
The alignment path 271 aligns the balls stored in the prize ball tank 27 into multiple rows and passes them to the prize ball payout mechanism 26.
It is intended to be supplied to A merging gutter 28 is formed below the prize ball payout mechanism 26. Merging gutter 28
integrates a gutter 281 that guides prize balls paid out from the prize ball payout mechanism 26 to the prize ball payout port 12, a gutter 282 that guides surplus prize balls to the surplus prize ball payout port 15, and a gutter 283 that guides out balls downward. It is constructed by molding.

FIG. 3 is a perspective view of the variable winning ball device 30.
This variable prize winning ball device 30 opens the opening/closing plate to the front to receive balls, which will be described later, as an example of a first state that is advantageous to the player, and an example of a second state that is disadvantageous to the player. This closes the opening/closing plate to prevent the ball from being received.

Next, a more specific configuration of the variable winning ball device 30 will be explained with reference to FIG. A through hole is formed in the center of the decorative frame 31, which becomes a winning area 32 in which a ball can be won. An opening/closing plate 33 is provided on the front side of the through hole so as to be freely openable on the front side. The lower side of the opening/closing plate 33 is supported by a shaft 331, and a U-shaped protrusion 332 is formed on the back surface of one side (the right side in the figure). A through hole is bored in the protrusion 332 .
A pin 3 fixed to the tip of the lever 34 is inserted into the through hole.
41 is inserted. The other end of the lever 34 is the fulcrum 3
42 is supported. At the upper position of the lever 34,
An opening/closing mechanism 35 for driving the opening/closing plate 33 to open or close is provided. The opening/closing mechanism 35 is a solenoid 351
One end of a rod 353 is connected to the plunger 352 of the solenoid 351, and the other end of the rod 353 is connected to the center of the lever 34.

The entry prize area 32 is divided into a plurality of areas 32a, 32b, and 32c as necessary. The winning balls in the winning areas 32b and 32c are directly guided to the back side of the game board 1 and reach the winning ball processing device 23 via a path 213. The winning area 32a is an area defined so that the opening/closing plate 30 of the variable winning ball device 30 can be repeatedly opened and closed in response to the passage of balls. Safe holes 36a and 36b are formed in the decorative frame 31 on both sides sandwiching the winning area 32. The safe holes 36a and 36b are arranged in the decorative frame 3 so that balls falling along the game board 1 can be received at all times.
It is formed to protrude to the front side from the first side, and guides fallen balls to the back side as winning balls. In the decorative frame 31 portion exposed when the opening/closing plate 33 is opened,
Light emitting diodes 6a and 6b are provided. In a specific game state, the light emitting diodes 6a and 6b
When the opening/closing plate 33 is opened, the winning area 32
Based on the occurrence of a winning ball in a, the opening/closing plate 33 is closed after a certain period of time and then repeated again to display that the conditions for opening the opening are satisfied.

In operation, the opening/closing plate 33 is connected to the solenoid 35
When the plunger 1 is energized and the plunger 352 is pulled up, it is opened to the front side as shown in the figure, which is advantageous to the player. On the other hand, when the solenoid 351 is deenergized, the plunger 352 is pushed downward, and the lever 34 is rotated downward. Therefore, the opening/closing plate 33 is closed, resulting in a disadvantageous situation for the player.

By the way, in the embodiment shown in FIG. 3, the opening/closing plate 33 is continuously opened as the first state, and the opening/closing plate 33 is closed as the second state, but various other states are possible in which it is easy to win a prize. It is also possible to make it difficult to win a prize. For example, in the first state, opening and closing may be alternately repeated a predetermined number of times at relatively short fixed time intervals (2 seconds).
In addition, as another example of the variable winning ball device, a device such as a so-called chulip may be used, and the second state may be a state in which it is difficult for balls to enter.

FIG. 4 is a front view of the variable display device 40. In construction, the variable display device 40 includes a segment display 41 that electrically displays a variable display, and a rotating drum display mechanism 50 that displays a variable display by mechanically rotating. Specifically, the variable display device 40 includes a segment display 41 provided on the upper part of the decorative frame 42, and a plurality of windows (three in the illustration) formed in the horizontal direction of the decorative frame 42 to display the rotating drums 51a, 51b. , 51c is housed in a rotating drum display mechanism 50 so that a portion of the drum display mechanism 51c can be visually observed. The segment display 41 displays numbers 0 to 9, and variably displays the numbers during a period that is approximately the same as the variable display period of the rotating drum display mechanism 50. The decorative frame 42 is provided with a plurality of light emitting diodes 7a to 7d in order to display the number of times the variable display device 40 can be variably displayed. Note that a segment display may be used instead of the light emitting diodes 7a to 7d as means for displaying the number of times the variable display device 40 can be variably displayed. In that case, the segment display 41 is used both to display the electrically variable display and to display the number of variable display possible, or another segment display is used. Note that details of the rotating drum display mechanism 50 will be explained with reference to FIG. 5.

FIG. 5 is a detailed perspective view of the rotating drum display mechanism 50. In the figure, a rotating drum display mechanism 50
The rotary drum group 51 included in the rotary drum group 51 includes multiple rows of rotary drums 51a, 51b, and 51c. Identification information such as a picture pattern, a symbol, or a number (for example, a picture pattern such as a bell, a star, a sailboat, or a number or a symbol such as an alpha alphabet) is drawn on the outer periphery of the rotating drums 51a to 51c in each row. On each side of the rotating drums 51a to 51c in each row, ratchet gears 52a to 52c (52c in the illustration) each have a number of teeth corresponding to the number of identification information drawn on the outer periphery.
(only shown) is fixed. Each of the rotating drums 51a to 51c in each row is loosely fitted onto the drum shaft 53 and supported so as to be individually rotatable by the frictional force thereof. The drum shaft 53 is pivotally supported on both sides of the box 54. A gear 551 included in the rotational force transmission mechanism 55 is fixed to one end of the drum shaft 53. The gear 551 is the gear change gear 5
52 and is meshed and coupled. A motor 56 for driving the rotating drum is attached to the side surface of the box 54. A geared motor is used as the motor 56, and its driving gear is coupled to the gear 552. The rotational force of the motor 56 is generated by the gears 522 and 551.
is transmitted to the drum shaft 53 via the rotary drum group 51 to rotate. Furthermore, solenoids 57a to 57c are fixed to the rear rear surface of the box 54 for individually controlling rotation or stopping of the rotating drums 51a to 51c in each row.
Plungers 571 of these solenoids 57a to 57c are connected to one ends of locking levers 58a to 58c, respectively, by pins. These locking levers 5
Approximately central portions of 8a to 58c are supported by a shaft 581. Both sides of the shaft 581 are fixed to both sides of the box 54. A claw-like portion 582 is formed at the tip of each of the locking levers 58a to 58c. The claw-like portions 582 of each of the locking levers 58a-58c engage with the corresponding ratchet gears 52a-52c, respectively, to stop the rotating drums in each row and maintain the locked state.

The specific game state that allows the variable winning ball device 30 to be in the first state for a relatively long time is a combination of identification information such as a picture pattern in each row displayed on the rotary drum display mechanism 50. The alignment condition and
It is determined in combination with the display state of numerical information displayed on the segment display 41.

Other examples of the specific game state include only the display state of the rotating drum display mechanism 50, only the display state of the segment display 41 when a plurality of digits are provided, or a specific winning state provided on the game board 1. The case may be based on any case where there is a ball passing through the area.

FIG. 6 is a game control circuit diagram of an embodiment of the present invention. In the configuration, the game control circuit 60 includes a variable display possible condition detection circuit 61, a decoder driver 62, a rotating drum drive control circuit 63, a display drive circuit 64, a specific game state detection means 65, a batting motor drive circuit 66, and a predetermined value imparting circuit. State detection circuit 6
7, and drive control means 70. Here, the variable display possible condition detection circuit 61 detects the variable display device 4.
A condition under which 0 can be displayed variably is detected and the number of times it is detected is counted. The decoder driver 62 drives the light emitting diodes 7a to 7d to display a display based on the number of times that the variable display device 40 can perform variable display. The rotating drum drive control circuit 63 drives and controls the rotating drum display mechanism 50 based on variable display enable conditions. The display drive circuit 64 drives the segment display 41 to display based on variable display enable conditions. The specific game state detection means 65 detects that a predetermined specific game state has been entered based on the combination of the display state of the segment display 41 and the display state of the rotary drum display mechanism 50. Note that the specific gaming state detection means 65 preferably includes a function of detecting a condition that allows the variable prize winning ball device to be in the first state not only in the specific gaming state but also in other gaming states. The predetermined value provision state detection circuit 67 detects a state in which a predetermined value is provided in a specific game state (for example, a state in which a relatively large number of prize balls set as the number of prize balls are provided). The drive control means 70 drives and controls the variable winning ball device 30, and its detailed circuit configuration is shown in FIG.

FIG. 7 is a detailed circuit diagram of the drive control means 70. This drive control means 70 includes a decoder driver 71, an OR gate 72, a driver 73, and a timer 7.

Contains 00. Here, the decoder driver 71 is
Based on the count value of a counter 706 included in the repeating opening/closing drive circuit 700 for a certain period of time, the segment display 8 displays the elapsed time during which the variable winning ball device 30 is in the first state.
The driver 73 drives the variable winning ball device 30 to the first state by energizing the solenoid 351 during the output period of the OR gate 72. As an example of setting the variable winning ball device 30 to the first state, the repeating opening/closing drive circuit 700 for a certain period of time makes it easy to continuously win the variable winning ball device 30 for a relatively long certain period of time (for example, t1 = 30 seconds). It is used as a period measuring means for measuring the period in the state.

Next, with reference to FIGS. 1 to 7, specific operations when playing a game with the pachinko game machine 10 of this embodiment will be explained. The player puts the ball borrowed from the ball rental machine into the ball waiting gutter 13, adjusts the strength of the ball by rotating the ball hitting handle 14, and then rotates the ball hitting handle 14.
Press a. A press signal (high level) from the ball-hitting handle 14a makes the transistor 661 conductive and supplies power to the motor 241. In response, the motor 241 rotates and the ball hitting hammer 24
By intermittently rotating the ball 3, balls are driven into the game board 1 one by one. In this way, when a player is playing a ball hitting game, the ball is hit into the safe hole 2a.
When a prize is won in either of ~2c or Yakumono 4a, 4b, the prize ball payout mechanism 26 is activated to control the payout of a predetermined number of prize balls for each winning ball. On the other hand, when the ball hits any of the winning areas 3a to 3c, the corresponding detection switch 22a to 22c is activated.
One of them derives a high level and OR gate 6
11 as an addition input to an addition/subtraction counter 612. The addition/subtraction counter 612 performs an addition operation each time there is an output from the OR gate 611 and performs a subtraction operation each time there is an output from the comparison circuit 613, and provides the counted value to the comparison circuit 613 and the decoder driver 62. The decoder driver 62 drives a number of light emitting diodes 7a to 7d corresponding to the count value of the addition/subtraction counter 612 for display. Comparison circuit 6
13, the output of the delay circuit 646 included in the display drive circuit 64 is given as a comparison command signal.
The comparison circuit 613 determines that when a high-level comparison command signal is input, the count value (n) of the addition/subtraction counter 612 is a value (for example, 1 or more; that is, n Based on the fact that ≧1), a high-level variable display command signal is derived. This variable display command signal is applied to the drive circuit 631 and as a set input to the flip-flop 641. Further, the output of the comparison circuit 613 is given as a subtraction command signal to the addition/subtraction counter 612, and the number of variable display possible times counted by the addition/subtraction counter 612 is subtracted by 1. The drive circuit 631 energizes the solenoids 57a to 57c to close the locking lever 58.
By disengaging the claw-like portions 582 of a to 58c from the corresponding ratchet gears 52a to 52c and driving the motor 56 to rotate, the rotating drums 51a to 51c in each row are driven to rotate. Change the display state of the drum. At the same time, the set output of flip-flop 641 is provided as one input of AND gate 642. This AND gate 642 has a clock oscillator 64
The clock pulse of output No. 3 is always given as the other input. For this reason, the AND gate 642
derives the clock pulse according to the set output of the flip-flop 641, and outputs the clock pulse from the ring counter 644.
give to The ring counter 644 cyclically counts the numerical values 0 to 9 that can be displayed on the segment display 41 according to the input of the clock pulse, and sends the counted value to the decoder driver 645 and the specific game state detection means 65. It is applied to the included determination circuit 655. The decoder driver 645 decodes the count value of the ring counter 644, and based on the count value, sequentially changes the number displayed on the segment display 41 at the cycle of the clock pulse. In this way, the rotating drums 51a to 5
By rotationally driving 1c and variably displaying the segment display 41, mechanically variable display and electrically variable display are performed simultaneously.

As described above, the rotating drums 51a to 51c
In a state where the segment display 41 is variably displayed, the player presses the stop command switch 18 so that the combination of display states of the rotating drums 51a to 51c in each row becomes a specific game state. In response to this, the drive circuit 631 deenergizes the solenoids 57a to 57c in a predetermined order (or an irregular order is also possible) to operate the rotating drum 51a.
~ 51c are sequentially stopped. And the drive circuit 6
31 stops the rotation of the motor 56 after a short delay, and also derives a high level signal indicating that all rotating drums have stopped. This high level signal resets the flip-flop 641 and is applied to the display state determination circuit 653 as a determination command signal. In response, AND gate 642 stops deriving clock pulses. Therefore, the count value of the ring counter 644 is not incremented, and therefore, the number corresponding to the count value counted by the ring counter 644 is continuously displayed on the segment display 41.

The display state determination circuit 653 determines the combination of identification information displayed on the rotating drums in each row based on the outputs provided from the sensors 651 and 652 in response to the determination command signal. Here, the sensors 651 and 652 are, for example, photoelectric sensors having a light projecting part and a light receiving part, and the light projecting part and the light receiving part are provided facing each other on both axially outer sides of the rotating drum in each row. And the rotating drums 51a to 51c
Although not shown in FIG. 5, on each side of the drum, there is a mark at a position corresponding to the identification information displayed on each rotating drum on the first circumference and the second circumference having different radii. , a portion with a through hole and a portion without a through hole are provided, and four types of identification are possible by the combination of the portion with a through hole and the portion without a through hole. 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", there are four types. 2-bit code “00”, “01”, “10”, “11”
Accordingly, the combination of identification information of the rotating drums in each row displayed in the window of the decorative frame 42 can be detected.
Then, the display state determination circuit 653 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 means 70 and the determination circuit 655. If the combination of identification information displayed on the rotating drums 51a to 51c is not a combination of a specific game state, that is, a combination determined to give the maximum value (for example, all sailboat shapes), the display state The determination circuit 653 derives one of the determination signals (or score signals) j2 to j4 indicating that a value smaller than the maximum value should be given based on the combination at that time. Each determination signal j2-j4 is given to a corresponding timer 74-76. Each timer 7
4, 75, and 76 are the corresponding determination signals j
2, j3, and j4, high-level signals are derived for predetermined fixed times t2, t3, and t4. Here, the fixed time set by the timers 74 to 76 is selected according to the relationship t2>t3>t4, for example, t2=10 seconds, t3=6 seconds,
t4=4 seconds is selected. Note that the determination circuit 655
If the determination signal is other than the signal j1 representing the specific game state (ie, j2 to j4), the display state of the segment display 41 is not determined at all.

For example, assuming that the display state determination circuit 653 derives the determination signal j2, the timer 7
4 derives a high level signal for a certain period of time t2. This high level signal is applied to the driver 73 via the OR gate 72. In response, the driver 73 continuously energizes the solenoid 351 for a certain period of time t2. Therefore, the variable winning ball device 30
The opening/closing plate 33 is opened for a predetermined period of time t2 to allow the hit ball to win. At this time, when the hit ball lands in the winning area 32b or 32c, the prize ball payout mechanism 26 pays out a predetermined number of prize balls in accordance with the winning ball. However, even if the hit ball enters the winning area 32a, the opening operation of the variable winning ball device 30 is not extended and only a predetermined number of prize balls are paid out for each winning ball. .

Next, a case will be described in which the combination of identification information displayed on the rotating drums 51a to 51c in each row is determined to give the maximum value. In this case, the display state determination circuit 653 derives the determination signal j1 and supplies it to the determination circuit 655 and also as a set input to the flip-flop 701. Accordingly, flip-flop 701 is set.
Further, the determination circuit 655 determines whether the count value of the ring counter 644 is in a display state (for example, a state in which 7 is displayed) giving the maximum value set in the combination setting section 654, in accordance with the determination signal j1. Determine whether or not. At this time, the determination circuit 655
Even if the combination of display states of the rotating drums 51a to 51c gives the maximum value, if the segment display 41 does not display the number 7, the maximum value provision command signal (high level) is derived. do not. That is, the determination circuit 655 continues to apply the low level signal to the AND gate 656.
In this case, the set output of flip-flop 701 set by determination signal j1 is passed through OR gate 702 to AND gates 703 and 70.
given to 4. At this time, the AND gate 704
, a low level signal representing that the predetermined time t1 has not elapsed is inverted to a high level signal and inputted from the comparison circuit 707. For this reason,
The AND gate 704 continuously derives a high level signal until the comparator circuit 707 detects a predetermined time t1, and supplies it to the driver 73 via the OR gate 72. Accordingly, the driver 73 activates the solenoid 351
is energized to open the opening/closing plate 33 of the variable winning ball device 30. At this time, the AND gate 703 has
A high level signal is given based on the depression of the batting command switch 14s. Therefore, AND gate 703 derives the pulse given from pulse generation circuit 705 and supplies it to counter 706 . Counter 706 increments its count value every time a pulse is input, and provides it to comparator circuit 707 and decoder driver 71 . Here, the pulse generation circuit 705
The pulse generation period is, for example, 1/10 seconds (or 1/10 seconds).
100 seconds). In this case, the decoder driver 71 selects the top two of the counted values of the counter 706.
The number of digits (that is, the number after the decimal point is rounded down) is displayed on the segment display 8 as opening duration data of the variable winning ball device 30. Comparison circuit 707
compares whether or not the count value of the counter 706 corresponds to the constant time t1 (that is, the value obtained by dividing the count value of the counter 706 by the period of the output pulse of the pulse generation circuit 705) reaches the constant time t1. , derives a high level signal when it is determined that the predetermined time t1 has been reached. This high level signal resets flip-flop 701 and counter 706, is applied to delay circuit 708, and disables AND gate 704. As a result, the variable winning ball device 30 is opened for a certain period of time t1, which is longer than when the determination signals j2 to j4 are derived, but it is not repeatedly driven to open.

On the other hand, the combination of the display devices of the rotating drums 51a to 51c is in a predetermined state (all figures of yachts) that can give the maximum value, and the segment display 4
When the display state of 1 changes to a state where the number 7 that can be assigned the maximum value is displayed, the determination circuit 655
derives a high level signal representing a specific gaming state, that is, the fulfillment of the maximum value granting condition. This high level signal sets the flip-flop 713 and is applied to the predetermined value provision state detection circuit 67. Therefore, when the specific game state is entered, the opening operation of the variable winning ball device 30 is repeatedly performed after the operation when the above-mentioned determination signal j1 is derived is completed. That is, in this case, when the variable winning ball device 30 is opened for a certain period of time t1 and then closed, the delay circuit 708 derives a high level signal after a certain period of time and supplies it to the AND gate 709.

By the way, the conditions under which the opening drive of the variable winning ball device 30 can be repeatedly performed in a specific gaming state are as follows.
This is a case where a winning ball hits the winning area 32a during the period when the variable winning ball device 30 is open. Therefore, if there is a winning ball in the winning area 32a,
A special prize ball detection switch 711 provided in connection with the winning area 32a detects a winning ball and sets a flip-flop 710. Therefore, the AND gate 709 detects that there is a set output of the flip-flop 713, that is, a specific gaming state, that there is a set output of the flip-flop 710, that is, that there is a winning ball in the winning area, and that there is an output of the delay circuit 708. That is, based on the three conditions that the variable winning ball device 30 is opened for a certain period of time t1 and then closed,
A high level signal representing a repeated opening command is derived and passed through the OR gate 702 to the AND gate 70.
3 and 704. As a result, the variable winning ball device 30 is opened again for a certain period of time t1 in the same manner as when the determination signal j1 is derived. At this time, AND gate 716 turns on transistor 717 in response to both set outputs of flip-flops 710 and 713, causing light emitting diodes 6a and 6b to emit light. By looking at the display states of the light emitting diodes 6a and 6b, the player can easily know that the variable prize winning ball device 30 will be opened again after being closed. In addition, the delay circuit 7
The output of 08 is given to a delay circuit 712. The delay circuit 712 derives a high level signal after a minute delay required to open and drive the variable winning ball device 30, and resets the flip-flop 710.
As described above, when the specific game state is entered, the variable winning ball device 30 is repeatedly opened and driven as long as there are winning balls in the winning area 32a during the period when the variable winning ball device 30 is opened. be able to. This provides the player with an opportunity to win a large amount of prize balls in an extremely efficient manner.

When the variable winning ball device 30 is repeatedly driven to open, if no winning ball enters the winning area 32a during that period, the flip-flop 710 continues to be in the reset state. Therefore, when the comparison circuit 707 detects that a predetermined time t1 has elapsed since the opening of the variable winning ball device 30, the AND gate 714 derives a high level signal and resets the flip-flop 713 via the OR gate 715. As a result, the repeated opening operation of the variable winning ball device 30 is thereafter completed. In addition, if winning balls are generated in the winning area 32a every time the variable winning ball device 30 is opened, the player can win a large amount of prize balls corresponding to the number of winning balls at an early opportunity. In this case, the predetermined value award state detection circuit 67 detects that a predetermined number of prize balls have been paid out, derives a high level signal to disable the AND gate 656, and also outputs a high level signal via the OR gate 715. Flip-flop 713 is reset. Therefore, the repeated opening operation of the variable winning ball device 30 for a certain period of time t1 is repeated for a certain period of time t.
It will be stopped if there are no winning balls in the winning area within 1 or if a predetermined value is given to the extent that it will be stopped.

By the way, as mentioned above, the variable winning ball device 30
When the ball is repeatedly opened and driven, a large amount of prize balls will be generated in a short period of time, so a large amount of prize balls will be paid out. Therefore, the player needs to transfer the prize balls stored in the prize ball tray 16 to another container. In this case, the player interrupts the ball hitting operation, prepares another container, and transfers the prize balls stored in the prize ball tray 16 to the other container. At this time,
Since the pressure on the batting command switch 14s is released, the AND gate 703 is disabled. Therefore, even if the batting game is stopped while the variable winning ball device 30 is being opened, the counter 706 stops counting the fixed time t1 during which the variable winning ball device 30 should be opened. In this way, when the variable winning ball device 30 is opened in a specific gaming state,
When the ball hitting operation is stopped, the timing operation of the fixed time t1 for opening the variable winning ball device 30 is stopped, and the state is displayed on the segment display 8. That is, when the player stops hitting the ball, the display of the opening time that has elapsed up to that point continues. in this case,
Since the ball hitting command switch 14s is not operated, the motor 241 is not supplied with electric power and therefore stops the ball hitting operation. In other words, the ball hitting command switch 14s constitutes an interruption condition detecting means for detecting that an interruption condition for stopping the pachinko ball firing by the ball firing mechanism and interrupting the game is satisfied. Note that the interruption condition may also be established by detecting the opening of a glass door or front frame, or the occurrence of an emergency situation such as a shortage of balls to be hit, or the establishment of the interruption condition by detecting the operation of an interruption button, etc. by the player. You may let them. Further, during the interruption of the game, the variable winning ball device may be placed in the second state as necessary. Furthermore, the first state of the variable winning ball device is changed to the predetermined time t1 when the number of winning balls reaches a predetermined number.
The process may be terminated without waiting for the elapsed time.

As a result, if the ball firing operation or ball hitting operation is interrupted during the opening of the variable winning ball device 30 in a specific game state, the interrupted time will not be counted as the time when the variable winning ball device 30 can be opened.
This has the advantage that the player can transfer the prize balls to another container with peace of mind. In addition, if the number of times that the variable winning ball device 30 can be repeatedly opened and closed in a specific gaming state is limited, or if there is one or a certain number of winning balls during one opening of the variable winning ball device 30, Even in the case where the conditions are set so that the player can repeatedly open the game, there is an advantage that the player will not be disadvantaged by interrupting the game while the variable winning ball device 30 is being opened.

In addition, in the above-mentioned embodiment, the segment display 8
Although the case has been described in which the time information displayed is the opening duration time of the variable winning ball device 30 in the specific game state, it may be the time t2 to t4 when the determination signals j2 to j4 are derived. In this case, the time information measured by the timers 74 to 76 is converted into a digital signal, and the gates are appropriately switched depending on the type of the determination signals j2 to j4 and then provided to the decoder 71. good. Further, instead of the opening duration time of the variable winning ball device 30, the remaining time that can be opened may be displayed. In this case, a subtraction circuit is used in place of the counter 706, and the circuit is configured such that at the timing when a high level is derived from the OR gate 702, a count value corresponding to a certain time t1 is preset in the subtraction circuit. The subtraction circuit performs a subtraction operation every time a pulse is input, and the subtracted value is provided to the comparison circuit 707 and the decoder driver 71. In this case, the comparison circuit 707
Instead, a device that detects when the count value of the subtraction circuit becomes zero is used.

Further, in the above-described embodiment, as an example of the first state, the opening/closing plate 33 of the variable winning ball device 30 is
Although the case of opening and closing has been described, it may be driven to open and close periodically (for example, at intervals of 2 seconds). In that case,
A pulse generation circuit that generates pulses at regular intervals is provided, and the output of the pulse generation circuit and the OR gate 72
The circuit is configured so that the output of the AND gate is given to the AND gate, and the output of the AND gate is given to the driver 73,
The opening/closing plate 33 may be opened only when the output of the AND gate is at a high level. In this case, the fixed time t1 is selected to be twice that of the case where the opening is continuous. Further, the numerical information displayed on the segment display 8 may display the number of openings instead of the fixed time. in this case,
It is sufficient to provide a counter that performs an adding operation every time the opening/closing operation is performed, and display the counted value of the counter on the segment display 8. In this case, the measurement period is a period that correlates to the product of the time corresponding to the period of the opening/closing operation and a certain number of opening/closing operations.

In addition, in the above-described embodiment, the case of replayable balls was described as an example of prizes paid out according to winning balls, but instead of this, valuable objects corresponding to a relatively large number of balls (for example, game A prize payout means that pays out a ball (or a metal ball larger than the ball) may also be used.

By the way, although the above-mentioned FIGS. 6 and 7 show a case in which a hardware circuit is used to achieve the operation of the present invention, the technical idea of the present invention is that it is constructed by program processing using a microprocessor. You can also do it with As for the operation in this case, a detailed explanation thereof will be omitted since those skilled in the art can easily imagine setting a program to perform the operation of the hardware circuit shown in FIGS. 6 and 7.

[Effects of the Invention] As described above, according to the present invention, even if the game is interrupted during the period in which the variable prize winning ball device is in the first state, the player can fully maintain the first state of the variable winning ball device. Therefore, it is possible to provide a pachinko game machine that does not cause any disadvantage to players, and to eliminate the dissatisfaction of players due to interruptions in play.
