Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a pachinko game machine, and more particularly to an improvement of a pachinko game machine provided with variable display means.

Description of Prior Art In general, pachinko gaming machines (hereinafter referred to as pachinko machines) that use pachinko balls to play games are widely used and are popular among players as one of the convenient cash registers. As is well known, a pachinko machine has multiple safe holes and a winning ball device on its game board.
When a player hits a ball, a certain number of prize balls will be released if the ball hits a safe hole or a prize ball with a certain probability. For this reason, the game tends to be monotonous because the player's operation is simply to hit the ball and compete for the ball to land in the safe hole or the yakumono.

In addition, for the purpose of providing services to players, conventional pachinko machines open a predetermined number of Yakumonos when a ball hits a certain safe hole or winning area, or play a predetermined Yakumono for a predetermined period of time. It was developed. For this reason, conventionally, even if prize balls are awarded depending on the gaming state, a predetermined number of prize balls are only created based on the winning balls, so the player has to play until the player stops the pachinko machine. If you wanted to win a large amount of prize balls, you needed excellent gaming skills and the patience to play continuously for a long time. For this reason, many experienced pachinko players, known as pachinko players, were able to win a large amount of prize balls on a single pachinko machine until it was controlled to stop. However, there is a desire for a gaming hall to provide many players with the opportunity to win a large amount of prize balls.

Therefore, the applicant of the present application first proposed Japanese Patent Application Laid-Open No. 56-80281
In the above publication, a pachinko machine was proposed in which a relatively large value can be given based on the display state of a variable display means. However, the previously proposed method had the problem that the variable display means of a particular pachinko machine would reach the maximum value imparting state many times in one day or over a certain period of time, causing the gaming hall to suffer a large loss. Ta. In addition, if only a specific pachinko machine was given the maximum value, only a specific player who knows the machine number of that pachinko machine would receive a large benefit, and many players would This results in a result that is contrary to the desire of the gaming hall to provide an opportunity to provide maximum value.

Purpose of the Invention Therefore, an object of the present invention is to be able to limit the number of times the variable display means reaches the maximum value imparting state in a pachinko machine provided with a variable display means, so that the gaming parlor suffers a large loss with a particular pachinko machine. To provide a pachinko machine that can give many players an opportunity to obtain maximum value without causing any problems.

Summary In summary, the present invention restricts, in a pachinko machine equipped with a variable display means, the variable display means from entering the maximum value giving state when the number of times the maximum value is given reaches a set limit number of times. It was designed to do so.

Hereinafter, specific embodiments of the present invention will be described with reference to the drawings.

DESCRIPTION OF EMBODIMENTS FIG. 1 is a front view of a pachinko machine according to an embodiment of the present invention. In the configuration, the pachinko machine 10 has the following configurations:
A front frame 11 is attached so as to be openable and closable, and a game board 1 is detachably attached to the front frame 11. The game board 1 includes safe holes 2a to 2c, which are examples of winning areas, winning areas 3a to 3c, which have conditions for variable display of a variable display device 40 (to be described later) depending on winning balls, and a plurality of Yakumono (commonly known as chulips). 4a, 4b, and an out ball inlet 5 are formed.

Further, a variable prize winning ball device (so-called electric ball device) 30 is arranged in the lower part of the game board 1.
The details of this variable winning ball device 30 will be explained with reference to FIG. 3, which will be described later. A variable display device 40, which is an example of variable display means, is disposed approximately in the center of the game board 1. Details of this variable display device 40 can be found in the fourth section.
This will be explained with reference to FIGS. 5C to 5C.

The front frame 11 is provided with a stop switch 12, which is an example of stop signal generating means, and a speaker 13. The stop switch 12 is used to stop the variable display of the variable display device by the player's operation. In addition, in the illustration, the stop switch 12 is set to 1.
However, each rotating drum included in the variable display device 40 (51a to 51a shown in FIG. 5A) is shown in FIG.
51c), a plurality of them may be provided. The speaker 13 is used to notify by voice that the maximum value awarding state has been reached or that the variable winning ball device 30 is in the open state.

FIG. 2 is an illustrative view of the back structure of a pachinko machine. On the back side of the safe holes 2a to 2c formed on the game board 1, there is a path 2 for guiding the winning balls won into the safe holes 2a to 2c to the upper part of the Yakumono 4a, 4b.
11,212 are formed. Winning areas 3a-3c
Detection switches 22a and 22c are provided on the back side of the player to detect the winning balls in the respective winning areas. These detection switches 22a to 22c
is used to detect a predetermined state in which the display state of the variable display device 40 can be changed by detecting winning balls in the winning areas 3a to 3c. Paths 213 and 214 are provided at an angle on the back side of the game board 1 at a position slightly above the out ball entrance 5. route 213,
214 are safe holes 2a to 2c and winning areas 3a to 214;
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 processing device 23 intermittently drops the winning balls guided through the path 213 one by one. A prize ball payout operation is performed using the balls dropped one by one by the winning ball processing device 23.

FIG. 3 is a perspective view of the variable winning ball device 30.
This variable winning ball device 30 has an opening/closing plate 33, which will be described later, as an example of a first state that is advantageous for the player.
The opening/closing plate 33 is opened to the front to receive balls, and as an example of the second state which is disadvantageous to the player, the opening/closing plate 33 is closed to prevent the ball from being received.

Next, the specific configuration of the variable winning ball device 30 will be explained. 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 openable and closable. 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 341 fixed to the tip of the lever 34 is inserted into the through hole. The other end of the lever 34 is supported by a fulcrum 342. An opening/closing mechanism 35 for driving the opening/closing plate 33 to open or close is provided at an upper position of the lever 34 . The opening/closing mechanism 35 includes a solenoid 351, and the solenoid 3
One end of the rod 353 is connected to the plunger 352 of 51, and the other end of the rod 353 is connected to the center of the lever 34.

The winning area 32 is divided into a plurality of winning 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 a specific area defined so that the opening/closing plate 33 of the variable winning ball device 30 can be repeatedly opened and closed in accordance with the passage of balls in the maximum value imparting state. Safe holes 36 are provided in the decorative frame 31 on both sides of the winning area 32.
a, 36b are formed. Safe holes 36a, 36
b is formed to protrude to the front side from the surface of the decorative frame 31 so as to always receive the balls falling along the game board 1, and guides the balls that have fallen to the back surface as winning balls.

Further, if necessary, a light emitting diode 37 is provided in a portion of the decorative frame 31 that is exposed when the opening/closing plate 33 is opened. The light emitting diode 37 closes the opening/closing plate 33 after a certain period of time in response to the occurrence of a winning ball in the winning area 32a while the opening/closing plate 33 is open in the maximum value imparting state. It is used to indicate that the conditions that allow the trade to be opened again have been met.

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, as an example of a variable winning ball device for giving maximum value,
The opening/closing board 33 is continuously opened as a state advantageous to the player, and the opening/closing board 33 is closed as a disadvantageous state for the player. It may be something that changes to a difficult state. For example, a relatively short fixed period of time (2 seconds) is advantageous to the player.
Opening and closing may be alternately repeated a predetermined number of times. In addition, as another example of the variable winning ball device, a so-called chulip may be used and a state in which it is difficult for the ball to enter may be used, which is disadvantageous to the player. As yet another example, a relatively large winning opening for receiving winning balls is formed in the lower part of the game board 1, and an obstacle is provided above the opening to prevent the balls from entering the winning area, thereby creating the maximum value imparting state. Based on this, the obstacle may be retracted to the back side of the game board 1 to make it easier to enter the prize opening.

FIG. 4 is a front view of the variable display device 40. In configuration, the variable display device 40 includes a segment display 41 and a rotating drum display mechanism 50. The segment display 41 electrically variably displays identification information such as numbers.
The rotating drum display mechanism 50 variably displays identification information drawn on its outer periphery by being mechanically driven to rotate.

Both sides of the shaft 561 are fixed to both sides of the box 532. A claw-like portion 562 is formed at the tip of each of the locking levers 56a to 56c. The claw-like portions 562 of each of the locking levers 56a-56c engage with the corresponding ratchet gears 52a-52c, respectively, to stop the rotating drums 51a-51c in each row and maintain the locked state.

The maximum value giving state that allows the variable winning ball device 30 to be in a state advantageous to the player for a relatively long period of time is, for example, the picture pattern of the rotating drums in each row displayed on the rotating drum display mechanism 50. It is determined by the combination of the identification information and the display state of the numerical information displayed on the segment display 41.

Further, in relation to the rotating drums 51a-51c, detection means 58a-58 for detecting identification information displayed by the rotating drums at predetermined positions.

Limit number setter 62, continuation number setter 63, reset switch 6 included in the reset signal generation circuit
4 and a probability adjustment switch 65 are provided.

Here, the limit number setting device 62 is, for example, a dip switch, and is used to set the number of times that the maximum value can be given in a certain period. In other words, the limit number setting unit 62 determines how many times the maximum value can be imparted in a certain period in order to limit the occurrence of a state that is determined to allow the maximum value to be imparted within a certain period. This is to set whether to start the operation of restricting (or prohibiting) the maximum value provision state from then on.

The limit number setting device 63 is used to set the number of times that the variable prize winning ball device 30 can be repeatedly brought into a state advantageous to the player after the maximum value giving state is reached.

The reset switch 64 generates a reset signal when operated. This reset signal is used to reset the number of times the maximum valuation condition has occurred during a period of time. Here, if the reset signal generating means is a manual switch such as the reset switch 64, the term "certain period" refers to the period from when the reset switch 64 is pressed to when it is pressed next time. Note that the reset signal generating means automatically generates the reset signal at certain times or periods (for example, every 24 hours, every 3 days, every week, etc.) using something like a timer means. It may be something that does. Further, as another example, a reset signal may be generated when the power is turned on when the store is opened. In that case, the reset switch 64 may be unnecessary, or a combination of these may be provided and the reset signal may be generated from one of the outputs.

FIG. 7 is a game control circuit diagram of an embodiment of the present invention. In the figure, the game control circuit of this embodiment includes a display start signal generation circuit 71 as an example of game state detection means, a mechanical display drive circuit 72, an electrical display control circuit 73, and a display stop signal as an example of stop signal generation means.

The maximum value imparting state detection circuit 75 includes a drum combination determination circuit 751 and a combination state detection circuit 752. The combination state detection circuit 752 is
This is a circuit for detecting that the combination of the mechanical display state of the rotating drum display mechanism 50 and the electrical display state of the segment display device 41 has become a combination determined to provide maximum value. .
In addition, if the variable display means is only a mechanical display means or only an electric display means,
The circuit is configured to detect whether each display state is a predetermined maximum value imparting state.

The maximum value imparting state limiting circuit 77 includes a counter 771 as an example of a counting means, a comparison circuit 772 as an example of a determining means, and a limit number setting device 62 as an example of a limit number setting means, and as needed, a reset signal generating means. An example of a reset signal generation circuit 773 is included. Here, the counter 771 is used to count the number of times the maximum value imparting state occurs in a certain period. Comparison circuit 772 is used to determine whether the number of occurrences of the maximum value imparting state in a certain period has reached the limit number of times. The reset signal generation circuit 773 is a reset switch as shown in FIG. 6, a timer that automatically generates a signal at fixed intervals, or a circuit that generates a reset signal when the power switch is turned on (for example, Differential circuit) etc. are used.
Alternatively, a combination of these may be used.

In this embodiment, as the value imparting means for imparting the maximum value, one is used that puts the winning ball device 30 in a state advantageous to the player for a relatively long period of time. For that purpose, the winning ball device drive circuit 76
includes an opening time control circuit 761, a driver 762, and a solenoid 351. Opening time control circuit 761 includes a clock signal generation circuit 761a. The clock signal generation circuit 761a generates a minute time (0.1 to 0.3
seconds) interval clock cl1 and 1 second clock cl2
is generated. Note that another example of the maximum value may be one that provides other value, such as one that directly pays out a relatively large number of prize balls.

As an example of the maximum value, when the variable winning ball device 30 is opened for a relatively long period of time, the continuation number limit circuit 78 is configured to repeat the operation again after closing when a condition is reached that allows the variable winning ball device 30 to be opened continuously during the opening period. This limits the number of times a user can open an account. For that purpose, the continuation number limit circuit 78 includes a continuation number setter 63, a repetition condition detection circuit 781, a counter 78

Contains 3.

Next, the specific operation of this embodiment will be explained with reference to FIGS. 1 to 8.

The operations of this embodiment include when the display state does not become the maximum value provision state, when the maximum value provision state occurs but the number of occurrences is less than the limit number of times, and when the maximum value provision state, which is a feature of this invention, occurs. There are three possible cases when the number of times reaches the limit number of times. Therefore, below, the operation will be explained separately for these cases.

(1) Operation when the display state does not reach the maximum value granting state In order to obtain the maximum value in a short time, the player can change the display state of the rotating drum display mechanism 50 and the segment display 41. The player plays the game with the aim of winning a prize in any of the winning areas 3a to 3c. At this time, the ball being driven into the safe holes 2a to 2c or the Yakumono 4a,
4b, a predetermined number of prize balls (prize balls) are released for each winning ball, similarly to conventionally known pachinko machines.

On the other hand, when the hit ball lands in any of the winning areas 3a to 3c, the winning ball is detected by the detection switch 2.
Detected at 2a to 22c. The respective outputs of the detection switches 22a to 22c are given to an addition/subtraction counter 711 as addition pulses.
The addition/subtraction counter 711 increments the count value by 1 each time an addition pulse is input, and provides the count value to the comparison circuit 712 . Comparison circuit 71
2 determines whether the count value of the addition/subtraction counter 711 is greater than or equal to a certain number (for example, 1) required to start variable display on the display device 40, and when it is determined that the count value is greater than or equal to the certain number, the start signal is AND gated. Give to 713. This AND gate 713 is connected to the output (high level) of the flip-flop 731 via a delay circuit 735, which will be described later.
is given. For this reason, and gate 7
13 gives a high level start signal to the motor drive circuit 721 and the solenoid drive circuit 722. Accordingly, the motor drive circuit 721 rotationally drives the motor 541, and the solenoid drive circuit 722 energizes the solenoids 55a to 55c. Therefore, the rotating drums 51a to 51c are rotationally driven to mechanically change the identification information. At the same time, the output of AND gate 713 causes flip-flop 731 to be set. Therefore, the output Q of flip-flop 731 becomes high level, activates AND gate 732, and is applied to display information generation circuit 80. AND gate 732 receives clock cl1 from opening time control circuit 761 while output Q of flip-flop 731 is at high level.
is derived and given to the display information generation circuit 80. This clock cl1 has a period (for example, from 0.1 to
0.3 seconds). In addition,
The operation of display information generation circuit 80 will be described later.

Further, the output of the AND gate 713 is given to the addition/subtraction counter 711 as a subtraction pulse, and is also given to the timer 741 as a signal instructing to start the timer operation. At this time, the output of flip-flop 31 becomes low level. This low level is delayed by a minute amount of time in the delay circuit 735 and provided as a signal for disabling the AND gate 713. For this reason,
Once the display state of the display device 40 begins to change, even if the count value of the addition/subtraction counter 711 exceeds a certain value set by the comparison circuit 712, derivation of the start signal is prohibited.

Next, the operation when changing the display state of the segment display 41, that is, the operation of the display information generation circuit 80 will be explained. Numerical information generation circuit 8
1 includes a decimal counter 81a. This decimal counter 81a increments its count value by 1 each time the clock cl1 is applied, and sequentially counts the numbers from 0 to 9.
Each time it is counted, the counted value is reset.
That is, the decimal counter 81a has numbers 0 to 9.
This is a ring counter that sequentially counts. This decimal counter 81a has count values 0 to 6, 8,
9, and a high level is derived from the output terminal corresponding to the count value.

By the way, in the maximum value imparting state, the combination of identification information displayed on the rotating drums 51a to 51c is a predetermined one (for example, all A), and the identification information displayed on the segment display 41 is a predetermined number (for example, 7). In this case, the output terminals of the count values 0 to 6, 8, and 9 of the decimal counter 81a are connected to the AND gate 81.
It is given as one input of 0 to 816, 818, and 819. AND GATE 810-816,8
18,819, the output of the inverter 81c is applied as the other input via the OR gate 81d. AND GATE 810~816,81
8, 819 is an output terminal for each corresponding count value of the decimal counter 81a when the output of the inverter 81c is high level, that is, when the output of the latch circuit 82e included in the probability adjustment circuit 82 is low level. When a high level is given from
give to The decoder 81b decodes the count value of the decimal counter 81a except for 7, and provides the output to the driver 733. Here, the reason why the count value 7 of the decimal counter 81a is not given to the decoder 81b is that the timing for displaying the number 7 is based on the output from the latch circuit 82e.

Next, details of the probability adjustment circuit 82 will be explained.
The variable pitch oscillator 82a is a variable resistor 82c.
The pulse generation period is changed by adjusting . For example, the variable pitch oscillator 82a
Clock the width of one of the output pulses of cl1
The probability that the number 7 is displayed can be changed by selecting the same period A (constant) and varying the pulse generation period B (where B>A). The output pulse of this variable pitch oscillator 82a is given as one input of an AND gate 82d. When the output Q of the flip-flop 31 becomes low level, the AND gate 82d is activated by the high level that is inverted and given by the inverter 82b, and the variable pitch oscillator 8
2a is derived from the latch circuit 82e.
give to However, until the variable display state is commanded to stop, the output Q of the flip-flop 731 is
is at high level, the variable pitch oscillator 8
The output pulse 2a is not derived, and therefore the latch circuit 82e continues to derive a low level. Therefore, during the period when the display state of the segment display 41 is changing sequentially, the number 7
A signal for displaying is not given to the decoder 81b.

When the stop switch 12 is operated by the player after or within a certain period of time set by the timer 741 after the start signal is derived from the AND gate 713, the OR gate 742 stops the variable display. Solenoid drive circuit 722 derives a stop signal for
give to This solenoid drive circuit 722 is supplied with a one-second clock cl2 from a clock signal generation circuit 761a. After the solenoid drive circuit 722 is given the stop signal, the solenoid drive circuit 722
Every time the second clock cl2 is applied, the solenoids 55a, 55b, and 55c are sequentially deenergized at one second intervals. Accordingly, the locking levers 56a, 56
The pawl-like portions 562 of b and 56c sequentially engage with the corresponding ratchet gears 52a, 52b, and 52c to sequentially stop each rotating drum 51a, 51b, and 51c. In addition, the solenoid drive circuit 72
2 derives a stop signal and supplies it to motor drive circuit 721 and delay circuit 734 in response to application of one-second clock cl2 after deenergizing solenoid 55c. Motor drive circuit 721
motor 54 in response to the input of the stop signal.
Deactivate. In this way, the rotating drums 51a~
The reason why the motor 541 is driven to rotate even after the rotation drum 51c has stopped is that even after each rotating drum has stopped, rotational force is applied to completely lock the ratchet gears 52a to 52c and the claw-like portions 562 of the locking levers 56a to 56c. This is to prevent the identification information displayed on the rotating drum from changing due to the forced state.

The delay circuit 734 resets the flip-flop 731 with a slight delay after the stop signal is applied. Therefore, the output Q of the flip-flop 731 becomes low level, and the output becomes high level. When the output Q goes low, the AND gate 732 is disabled, so that the clock cl1 is no longer applied to the decimal counter 81a. Therefore, the decimal counter 81a
stops incrementing the count value. At the same time, inverter 82b derives a high level to provide a latch command signal to latch circuit 82e, and activates AND gate 82d.
At this time, if the output pulse of the variable pitch oscillator 82a is at a low level, the latch circuit 82e reads and holds the low level, and its output remains at the low level. When the output of latch circuit 82e is at a low level, AND gate 83a remains disabled, so that a signal for displaying the number 7 is not provided to decoder 81b. Therefore, the decoder 81b decodes the count value of the decimal counter 81a and causes the segment display 41 to continuously display the count value.

At this time, the detection means 58a to 58c detect identification information displayed on the display window by each of the rotating drums 51a to 51c, and provide the identification information to the drum combination determination circuit 751. The drum combination determination circuit 751 determines whether the combination of identification information displayed on each of the rotating drums 51a to 51c is a combination determined to give the maximum value, or other combinations that have a relatively small value. Determine whether or not it is specified to be given. The determination result of the drum combination determination circuit 751 is provided to a combination status output circuit 752 and an opening time control circuit 761. The combination state detection circuit 752 determines whether the combination of the rotating drums 51a to 51c is a combination determined to provide the maximum value (for example, all A).
Or, even if the combination is determined to give the maximum value, if the identification information displayed on the segment display 41 is not the number 7, it is detected that the maximum value is not given, and the output is set to a low level. Leave as is. Therefore, the opening time control circuit 761 is controlled by the clock signal generation circuit 76.
The driver 762 is activated until the 1 second clock cl2 of 1a is applied a number of times corresponding to a relatively short period of time (eg, 5 seconds). The driver 762 energizes the solenoid 351 for a relatively short period of time to open the variable winning ball device 30.

(2) Operation when the maximum value provision state is reached and the number of occurrences of the maximum value provision state in a certain period is within the limit number of times Rotating drums 51a to 51c in this case
The driving and electrically variable display operations of the segment display 41 are the same as in the case (1) above. Then, the output Q of flip-flop 731
At the timing when changes to low level,
When the output pulse of the variable pitch oscillator 82a is at a high level, the high level is output to the latch circuit 8.
Latched at 2e. Therefore, the latch circuit 8
The high level output of 2e is given as one input of an AND gate 83a, and is inverted to a low level by an inverter 81c and then output to AND gates 810 to 816 through an OR gate 81d.
818 and 819 are inactivated. At this time,
The output of the comparator circuit 772 is inverted by an inverter 83b and provided as the other input to the AND gate 83a. However, the comparison circuit 772
sets its output to a low level if the number of occurrences of the maximum value imparting state is within the limit number of times. Therefore, this low level is connected to the inverter 8.
3b, it is inverted to high level and is applied to the AND gate 83a. Therefore, in response to the latch circuit 82e latching the high level, the AND gate 83a provides a signal for commanding the display of the number 7 to the decoder 81b. The decoder 81b decodes the number 7,
to the driver 733 to display the segment indicator 4
Display it as 1.

Also, the output of the flip-flop 731 is
It is differentiated by a differentiation circuit 736 and given as a determination command signal to a drum combination determination circuit 751 and a combination state detection circuit 752. The drum combination determination circuit 751 selects the rotating drum 51a.
It is determined that the combination of identification information displayed in ~51c is a combination determined to give maximum value, and the determination result is provided to the combination state detection circuit 752 and the opening time control circuit 761. . Combination state detection circuit 752
detects that the combination of drums is in the maximum value provision state and the display state of the segment display 41 is number 7, and sets the output to a high level. do. This maximum value imparting state detection output is given to the opening time control circuit 761 as a signal for instructing to give the maximum value, and is also given to the counter 771 as an addition pulse, and is further given to the repetition condition detection circuit 781 as an activation signal.
given to.

On the other hand, the counter 771 increments its count value in response to the input of the addition pulse. At this time, the comparator circuit 772 determines whether the count value of the counter 771 has reached the limit number set by the limit number setter 62, and if it determines that the limit number has not been reached, the output is set to a low level. Leave as is.

The opening time control circuit 761 activates the driver 762 for a relatively long period of time (for example, 30 seconds) in response to the maximum value provision state detection output.
Therefore, the driver 762 energizes the solenoid 351 for a relatively long time to open the variable winning ball device 30. At this time, if necessary, the user may be notified by voice that the opening period is in progress.

If even one winning ball enters the winning area 32a during the opening period of the variable winning ball device 30, the repetition condition detection circuit 781 detects it and supplies it to the counter 782 as an addition pulse. The counter 782 cumulatively counts the number of times the repetition condition is detected. And opening time control circuit 761
After closing the variable winning ball device 30, it gives a gate opening signal to the gate circuit 783. Therefore, the count value of the counter 782 is
is given as a comparison input. Comparison circuit 784
compares the number of continuation settings n1 set by the number of continuation setting device 63 with the count value n2 of the counter 782, and when it determines that n1 is larger (that is, n2 is less than or equal to n1 of the continuation setting circuit), it sets the high level. It is derived and given to the differentiation circuit 785. This high level is differentiated by a differentiation circuit 785 and given to the opening time control circuit 761 as a signal for repeatedly issuing an opening command. Accordingly, the opening time control circuit 761 again opens the variable winning ball device 30 for a relatively long fixed period of time (30 seconds).
Then, when the number of times the variable winning ball device 30 is repeatedly opened for a relatively long fixed period of time reaches the set number of continuations n1, the count value n2 of the counter 782 increases.
It will be equal to n1. When the comparison circuit 784 determines this, it thereafter stops deriving the repeated opening command signal and applies a reset signal to the counter 782 to reset the counter 782.

In this way, once the state of maximum value is reached, until a relatively large value is added,
The variable winning ball device 30 will be opened repeatedly.

The operation for maximizing value as described above is
This is performed each time the combination state detection circuit 752 detects the maximum value adding state.

(3) The number of occurrences of the maximum value state is limited to the number of times m1
As described above, the combination state detection circuit 752
Each time the maximum value imparting state is detected, the counter 771 cumulatively counts the number of times this has occurred. Then, the count value m2 of the counter 771 is the limit number of times set by the limit number setter 62.
When m1 is reached, the comparator circuit 772 detects it and sets its output to high level. For this reason,
The high level output of the comparator circuit 772 is inverted to low level by the inverter 83b and applied to the AND gate 83a.
3a is disabled. Therefore, when the number of occurrences of the maximum value state reaches the limit number m1,
After that, even if the latch circuit 82e latches a high level, the high level is not given to the decoder 81b as a signal for commanding the display of the number 7. In other words, if the number of occurrences of the maximum value imparting state reaches the limit number, the segment display 41 is prohibited from displaying the number 7 from now on, so the occurrence of the maximum value imparting state is prohibited. . However, when the latch circuit 82e latches the high level, the inverter 81c
Since the output of the comparator circuit 77 becomes low level, the comparator circuit 77
The high level output of 2 is passed through the OR gate 81d to the AND gates 810 to 816, 818, 81.
It will be given to 9.

In the above-described embodiment, when the number of occurrences of the maximum value provision state reaches the limit number of times, the occurrence of the maximum value provision state is prohibited from occurring thereafter. However, as another example of limiting the occurrence of the maximum value imparting state, the probability of its occurrence may be reduced. In that case, when the comparator circuit 772 outputs, the period B of the variable pitch oscillator 82a may be forced to be the longest regardless of the setting of the variable resistor 82c.

(4) Operation when changing the period during which the number of occurrences of the maximum value state should be limited After the number of occurrences of the maximum value state reaches the limit, the occurrence of the maximum value state is prohibited from occurring as described above. be done. In order to release this prohibited state, the following operation is performed. for example,
When an attendant at a game parlor wants to release a pachinko machine that has reached the limit number of times and wants to release the prohibited state, he or she presses the reset switch 64. In response, the count value of the counter 771 is reset (0), so that the output of the comparison circuit 772 becomes low level. For this reason, and gate 83
a is then activated and the number 7 can be displayed. In this manner, when the number of occurrences of the maximum value state since the reset switch was last pressed reaches the limit number of times, the reset switch 64 is then pressed.
Depending on the period or time until it is pressed,
The period during which the occurrence of the maximum value adding state is prohibited can be freely changed.

On the other hand, if the reset signal generation circuit 773 is constituted by a timer means, by generating a reset signal at a fixed period or time interval, the restriction on the maximum value adding state is automatically lifted at that cycle. That will happen.

The same applies even if the reset signal generating circuit 773 generates the reset signal when the power switch is turned on.

In addition, in the above-mentioned embodiment, the case where a mechanical variable display and an electrical variable display are combined is described as an example of the maximum value imparting state, but the present invention is not limited to this, and the case where only one of them is used is also possible. It's okay. In particular, when only electrically variable display means are used, the segment display is provided with a plurality of digits, and the display of the number 7 is restricted so that one digit can give the maximum value. In addition, in the case of only a mechanical variable display, the stop timing of the rotating drum 51c, which is the last stop after the stop signal is given, is determined by the combination of identification information displayed on each rotating drum in the maximum value adding state. What is necessary is to change the circuit of the solenoid drive circuit 722 so that it can be shifted by a minute amount of time to prevent this from happening.

Furthermore, in the above-described embodiment, the reset signal generation circuit 733 is provided for each pachinko machine, but a management device installed at a location away from the pachinko machine can be used to remotely read the machine number of the pachinko machine. The configuration may be such that the reset signal is specified and given.

Furthermore, in the above-mentioned embodiment, as an example of the game control circuit, a case was explained in which a hardware circuit was used. Needless to say, it is also possible to store the information and perform software processing based on the program.

Effects of the Invention As described above, according to the present invention, it is possible to limit the number of times that the maximum value imparting state occurs in a certain period of time, so it is possible to prevent the gaming hall from suffering a great disadvantage, and it is possible to limit the number of times that the maximum value imparting state occurs in a certain period. Unique effects such as being able to prevent maximum value from being added are produced.

Furthermore, if a reset signal generating means is provided, it is possible to cancel the occurrence restriction state of the maximum value granting state at any timing or periodically, giving many players an opportunity to give the maximum value, and providing uniform service. It has the advantage of being able to improve
