[Detailed description of the invention]

``Industrial Application Field'' The present invention relates to a pachinko game machine, and more particularly to a pachinko game machine that is capable of converting and controlling probability values in random number control of a variable display device. ``Conventional technology'' As is well known, the many pachinko machines installed in game arcades are classified into so-called collection machines, service machines, play machines, etc., depending on the nail adjustment, etc., even if they are of the same type, each with a different ball payout rate. However, the game machines are able to provide a reasonable level of gambling and service to many players through their machine setting techniques, and ensure overall profitability, and the majority of the management of the game centers is based on this adjustment. It depends on the technique of setting the table. By the way, the classic pachinko machine that has been known for a long time is one that pays out a predetermined number of pachinko balls by winning a prize in a predetermined winning area, and with this type of gaming machine, the outcome of the game depends on the skill of the player. However, it is extremely rare for an average player without advanced skills to win a large number of prize balls. Therefore, in order to provide services that are appropriate for the average player, and to increase their gambling spirit, in recent years, the game board has been designed to display conditions that are advantageous to the player, as well as information that is beneficial to the player. A variable winning device that can be converted into an unfavorable state, and a variable display device that converts the variable winning device into an advantageous state for the player in response to a specific display mode that occurs with a certain probability, 2. Description of the Related Art Pachinko gaming machines that allow a large number of prize balls to be won depending on the result of a game played using a variable display device are widely used. In general, in the case of pachinko gaming machines equipped with this type of variable display device, the probability of occurrence is low, and when a predetermined display mode occurs with a certain probability, the variable winning device is opened to a state with a high winning rate, and the prize ball is extremely efficiently played. Since the player can win a large amount of prize balls, even the average player can sometimes have the opportunity to win a large amount of prize balls, and thus has gained the support of many players. To describe the general operation of this type of pachinko game machine, the variable display device is activated due to a winning in a certain winning area, and when a predetermined display mode occurs, although the probability is extremely low, the The winning device is controlled in a manner that is extremely advantageous to the player. For example, specifically, a three-digit variable display device that is activated by winning a prize in a specific winning area is provided on the game board, and when this variable display device enters a specific display state such as [7.7.7], By operating such a variable prize winning device for a long time, the player can efficiently win a large amount of prize balls. "Problems to be Solved by the Invention" By the way, since game parlors also operate as businesses, the higher the profit that can be given to players when the variable display device adopts a specific display mode, the more likely they are to play games. The store has no choice but to keep the occurrence rate of the specific display format low, and as a result, the expectations of the players will be disappointed, and conversely, the profits given to the players when the above specific display format occurs will be reduced. If the price is not so high, the game parlor can increase the incidence of that particular display format, but
If that happens, players' desire to shoot will decline. Therefore, for example, to the extent that a game parlor can earn a certain amount of revenue and provide fair and appropriate services to players, the occurrence rate of a particular display format can be varied, and the specific display format can be obtained. It sets the profit that will be given when However, in the case of conventional pachinko gaming machines of this type, the probability value in the random number control of the variable display device is fixed to a constant value, and the variable display device is activated due to winning in the above-mentioned specific winning area. , or it stops working, so if the winning rate in that specific winning area decreases due to nail adjustment or other factors, the occurrence rate of the specific display mode will decrease significantly, and conversely, the winning rate in that specific winning area will decrease significantly. If the winning rate increases due to some factor, the occurrence rate of the specific display mode mentioned above will increase significantly, so it has traditionally been difficult to make appropriate adjustments to this type of gaming machine, making it difficult to provide appropriate service to players. It was said to be a platform that made it difficult to grasp the profitability of gaming and amusement arcades. The present invention has been made in view of the current situation, and includes a variable prize winning device that can convert between an advantageous state for the player and a disadvantageous state for the player, and a specific winning system that occurs with a certain probability. Controlling the conversion of probability values in random number control of the variable display device, assuming a pachinko game machine equipped with a variable display device that converts the variable prize winning device into a state advantageous to the player in accordance with the display mode. The purpose is to provide a pachinko game machine that can. "Means for Solving the Problems" To summarize, the pachinko game machine of the present invention is provided on the game board surface, and has a first game state that is advantageous to the player and a second game state that is disadvantageous to the player. a variable prize winning device capable of providing a variable prize winning device; a variable display device provided on the game board surface and capable of variably displaying identification information;
Random number generation means for generating random numbers within a set numerical data range; Numerical range storage means for variably storing the range of random numbers generated by the random number generating means; and Numerical range storage corresponding to the profit status of the gaming parlor. a rewriting signal generating means for generating a rewriting signal for rewriting the storage contents of the means; and a numerical data rewriting control means for rewriting the numerical data range stored in the numerical range storage means based on the rewriting signal generated by the rewriting signal generating means. , a start signal generation means for generating a start signal for converting and driving the variable display device, a stop signal generation means for generating a stop signal for stopping the conversion drive of the variable display device, and the start signal generation means converting and driving the variable display device based on the random number generated by the random number generation means in response to the output of the device, and stopping the conversion drive of the variable display device in response to a stop signal generated by the stop signal generation device. a display drive control means for determining whether the display mode of the variable display device has become a specific mode when the conversion drive of the variable display device is stopped; The above object is achieved by providing a variable winning device drive control means for causing the variable winning device to provide the first gaming state. "Function" In a variable display game using a variable display device, when the display determining means determines a specific mode among the display modes of the variable display device, the variable winning device drive control means controls the variable winning device to be advantageous to the player. A first gaming state is provided. In this random number control of the variable display device, the numerical range storage means stores a numerical data range, and the random number generation means generates random numbers within the numerical data range set in the numerical range storage means. During the game, the numerical data range stored in the numerical range storage means is rewritten by the numerical data rewriting control means by the output of, for example, a difference calculation circuit as the rewriting signal generating means. Therefore, since the variable display device is controlled in accordance with the random numbers within this rewritten numerical value range, the probability value of the occurrence of the specific display mode can be controlled. "Embodiments" Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a pachinko game machine 10 to which the present invention is applied.
The pachinko game machine 100 shown in the figure collects various winning ball devices 103 and non-winning pachinko balls in a game section 102 surrounded by a guide rail 101, like a normal game machine. An out hole 104 is provided, and the gaming section 102
Below is a supply tray 105 that guides pachinko balls purchased by players to the ball hitting position and dispenses prize balls.
Furthermore, there are provided a tray 106 for dispensing surplus prize balls that cannot be refunded to the supply tray 105, and a ball hitting device 107 for hitting pachinko balls to individual balls. Furthermore, the pachinko gaming machine 100 has a gaming section 1.
In this preferred embodiment, the game device has a specific ball winning area 201 which also serves as a winning area and is the cause of starting the game, and a front surface of the gaming machine. A stop switch 202 as an example of a stop signal generating means provided in It is constituted by a variable prize winning device 401 etc. which controls the opening mode and pays out a predetermined number of prize balls in response to winnings inside. To explain the configuration and operation of this game device in detail, the variable display device 301, which is basically composed of a two-digit, seven-segment display panel, changes its display mode in response to numerical information added from a control system, which will be described later. The numerical information is updated due to winning in the specific ball winning area 201, and the updating is stopped at the timing when the player presses the stop switch 202. Therefore, the display on the variable display device 301 also shows the specific ball winning area 20.
Updated by winning 1, stop switch 2
By pressing 02, the update is stopped. Then, the opening mode (for example, opening time, number of openings, opening angle, etc.) of the variable winning device 401 is controlled in accordance with the display mode of the variable display device 301 at that time, thereby providing a first state advantageous to the player. Whether or not to do so is controlled. The essential feature of the variable winning device 401 is that it is a winning device that can provide a first gaming state that is advantageous to the player and a second gaming state that is disadvantageous to the player. Various types of prize-winning devices having such characteristics have been known in the past, and in the present invention, there is basically no problem in using these conventionally known prize-winning devices. As an example of controlling the opening mode of the variable winning device 401, for example, if the display mode of the variable display device 201 becomes [7.7] and the game ends, the player opens the variable winning device 401 for 20 seconds. If the game ends with the display mode of the variable display device 201 other than [7.7], the variable prize winning device 401 is set to 20.
For example, in order to clearly notify the end of one game without providing the first state that is advantageous to the player, which is to open the winnings in seconds, the variable prize winning device 401 may be
The second state, which is disadvantageous to the player, is maintained by only opening for 0.6 seconds. According to a conventionally well-known control device, the display mode of this variable display device 301 is determined according to the random numbers generated by the random number generator and the count value of the ring counter, and the so-called jackpot is determined based on the number of games played. Therefore, if the winning probability for the specific ball winning area 201 increases due to some factor, the number of games per unit time will increase, so the probability of jackpot occurrence per unit time will also increase; When the probability of winning a prize in the specific ball winning area 201 decreases, the number of games per unit time decreases, and the probability of a jackpot per unit time also decreases. Therefore, in the embodiment of the present invention, by controlling the probability of the variable display device 301 hitting the jackpot in accordance with the profit status of the gaming parlor, the probability of winning the jackpot in the variable display device 301 can be adjusted even if the number of games per unit time increases or decreases. It is controlled so that the probability of jackpot occurrence is equalized. For example, in a preferred embodiment, assuming a method in which the display mode of the variable display device 301 is controlled in accordance with the random numbers generated by the random number generation section, according to the embodiment of the present invention, the display mode of the variable display device 301 is controlled in accordance with the random numbers generated by the random number generation section. Assuming that the range can be set by the program, if the profit status of the gaming parlor is high (normally, if the profit status of the gaming parlor is high, the probability of winning in the specific ball winning area 201 is low and the probability of a jackpot per unit time is considered to be low) ) narrows the range of random numbers generated by the random number generator to increase the probability of a jackpot, and conversely, if the profitability of the gaming parlor is low, it widens the range of random numbers generated by the random number generator. This is designed to reduce the probability of a jackpot. Next, FIG. 2 is a conceptual diagram of the back mechanism of the embodiment of the present invention. To explain its structure and operation with reference to FIG. 2, first, an upper tank 501 is provided on the back side of the pachinko game machine 100 in which the pachinko balls to be paid out to players are stored. Pachinko balls are supplied from 501 to a prize ball ejecting device 504 via a tank shoot 502 and a prize ball number setting device 503, and this prize ball ejecting device 5
04 holds the number of pachinko balls set by the prize ball number setting device 503. In addition, the prize ball number setting device 503 is equipped with a ball counting means (not shown), and when the pachinko balls held in the prize ball ejecting device 504 are ejected, a preset number (for example, 15) of pachinko balls are ejected. tank shoot 5
02 to the prize ball ejecting device 504. Further, on the back side of the pachinko gaming machine 100, there is provided a winning ball collection gutter 505 for collecting winning pachinko balls from any of the winning areas 103.
The pachinko ball flowing down 05 is the winning ball detector 506
While turning on the ball, the balls are temporarily collected in the ball receiving box 507, and then collected in a collecting device (not shown) located below the pachinko gaming machine 100. Therefore, when a pachinko ball wins in any of the winning areas 103, the pachinko ball is detected by the winning ball detector 5.
06 is turned on, and the winning ball detector 506 generates a winning ball detection signal. When this winning ball detection signal is applied, the prize ball ejecting device 504 discharges the pachinko balls held inside, and these pachinko balls pass through the prize ball ejecting path 508 to the supply tray outlet 1051.
from there to the supply tray 105. Also, if the supply tray 105 is full at this time, the prize ball will flow from the tray outlet 1061 to the tray 10 via the branch channel 509.
It is discharged at 6. In this way, the prize ball ejecting device 5
When 04 pachinko balls are ejected, the prize ball number setting device 503 again supplies a predetermined number of pachinko balls to the prize ball ejecting device 504 in preparation for the next winning ball. Furthermore, the pachinko balls that have flowed into the out hole 104 are once collected in the ball receiving box 507, and then a collection device (not shown) located below the pachinko game machine 100
will be collected. Therefore, the hit ball detector 5 is located at the exit of the ball receiving box 507.
10, it is possible to detect the number of pachinko balls hit by a player regardless of whether they are safe balls or out balls. In the embodiment of the present invention, the winning ball detector 50
Winning ball detection signal and batted ball detector 5 that generates 6
The batted ball detection signal generated by No. 10 is added to the control system 600, and the control system 600 grasps the profit status based on the number of winning balls and the number of batted balls, and controls the game device according to the profit status. It is designed to be controlled. The details of the control operation will be described later, but in addition to the above signals, the control system 600 collects signals from the specific ball winning area 20 to control the game device.
Starting signals A, B, and C generated by the specific ball detector 203 as a starting signal generating means when winning a prize in 1,
There is a stop signal D generated by the stop switch 202 when a player presses the stop switch 202, and the control signals outputted by the control system 600 include a display drive signal E for driving the variable display device 301 and a variable prize winning device 401. There is a variable prize winning device drive signal F etc. for driving. In addition, a winning ball detector 506 that detects a winning ball, a hit ball detector 510 that detects a hit ball, and a specific ball detector 2 that detects a winning ball that enters the specific ball winning area 201.
03 etc. in Fig. 2, only the installation position is shown and its specific structure is not particularly shown, but this type of detector is generally known to those skilled in the art, and is used for pachinko balls. This can be easily obtained by arranging a micro switch whose contacts open and close when the pachinko ball passes through it, a photoelectric sensor whose optical path is interrupted when the pachinko ball passes through the path of the pachinko ball. Next, FIG. 3 is a block diagram showing the principle of the control system of this embodiment. It is composed of Profit calculation means 6 constituting these control systems 600
10・Profit giving means 620・Profit giving control means 6
Although the specific configuration and operation of the game machine 30 will vary depending on the configuration of the pachinko game, the configuration and operation when applied to the preferred embodiment shown in FIG. 1 will be described below. First, to describe its functions: (1) The profit calculation means 610 uses the winning ball detector 506.
The winning ball detection signal that is generated and the batted ball detector 51
(2) The profit giving means 620 controls the display mode of the variable display device 301 to calculate the number of profitable balls of the pachinko gaming machine 100 based on the batted ball detection signal that generates a zero. In addition to making this a so-called jackpot display mode, the variable winning device 4 corresponds to the display mode of the variable display device 301.
(3) The profit granting control means 630 controls the profit calculation means 6.
The operation of the profit giving means 620 is controlled according to the number of profitable balls of the game parlor calculated by 10. Therefore, according to the embodiment of the present invention, when it is determined that the profits of the gaming parlor are high based on the information generated by the profit calculation means 610, the profit giving means 620 is activated so that the profits of the players increase. On the other hand, when it is determined that the profit of the game parlor is low, the profit giving means 620 is operated so that the profits of the players decrease. A feedback loop is essentially formed through the route of granting means 620 → profit calculating means 610, and it becomes possible to freely control the payout rate in accordance with the profit status of the gaming parlor. Next, FIG. 4 shows a specific configuration example of the profit calculation means 610, the profit giving means 620, and the profit giving control means 630 that constitute the control system 600 of this embodiment. First, the profit calculation means 610 includes a multiplication circuit 611.
The winning ball detection signal generated by the winning ball detector 506 is multiplied by a predetermined multiplication factor by the multiplication circuit 612 and then outputted by the difference calculating circuit 613. The hit ball detection signal that is applied to the subtraction terminal and generated by the hit ball detector 510 is directly applied to the addition terminal of the difference calculation circuit 613. Then, the difference calculation circuit 613 subtracts the number of returned balls added to the subtraction terminal from the number of batted balls added to the addition terminal, and outputs the result to the output terminal. Therefore, the number of profitable balls at the gaming parlor is derived from the output terminal of the difference calculation circuit 613 as shown by the following equation. Number of earned balls = Number of batted balls - (Number of winning balls x Prize ball rate) The multiplication rate setting device 612 is for setting the number of prize balls for winning balls, and it is particularly desirable that the multiplication rate setting device 612 If the number of prize balls is set in conjunction with the prize ball number setting device 503 that supplies a predetermined prize ball to the prize ball ejecting device 504, it will be possible to set the number of prize balls with a single operation. Further, the profit giving means 620 displays numerical information on a 7-segment LED which is a component of the variable display device 301.
Decoder drivers 621 and 62 as display drive control means for displaying on the display devices 302 and 303 of
2, a display determining means 624 that determines the display mode of the variable display device 301, and a variable prize winning device drive control means 625 that controls the opening time of the variable winning device 401 in accordance with the determination result of the display determining means 624;
A solenoid 626 is provided to open the variable winning device 401 within the time period in which the variable winning device drive control means 625 outputs a drive signal. In this embodiment, when the player presses the stop switch 202 after the specific ball detection signal is generated, the display determining means 624 determines the display mode of the variable display device 301, and transmits the determination result to the variable prize winning device drive control means 625. In addition, the variable prize winning device drive control means 625 operates the solenoid 6 in response to the determination result.
26 for a predetermined period of time to open the time-varying winning device 401, and after the elapse of that time, the display discriminating means 624 is initialized to prepare for generation of the next specific ball detection signal. In this embodiment, the variable winning device drive control means 625 applies a drive signal to the solenoid 626 for 20 seconds when the variable display device 301 is in the display mode of [7.7] when the player presses the stop switch 202. When the variable display device 301 is in a display mode other than [7.7] when the user presses the stop switch 202, a drive signal is applied to the solenoid 626 for 0.6 seconds. Since this variable winning device 401 is a winning ball device configured to improve the probability of winning inside when opened, when the variable display device 301 changes to the display mode [7.7] as a result of the slot game being played. The profits of the players will be increased, and the frequency with which this [7.7] display format occurs per unit time has a significant relationship with the profits of the players, and at the same time will affect the profits of the gaming parlor. It also has an important relationship. Therefore, in this embodiment, the profit giving control means 63
0 controls the probability that the variable display device 301 will have a display mode of [7.7] based on the number of profit balls of the gaming parlor calculated by the profit calculation means 610. That is, in the embodiment of the present invention, the profit grant control means 630 includes a random number generation section 631 as a random number generation means that generates random numbers (numeric data) within a set range.
, a random number range setting section 632 as a numerical range storage means that variably stores the range of random numbers generated by the random number generation section 631, and a numerical data rewriting control means that rewrites the set value of the random number range setting section 632 and performs various timing controls. The control section 633 is configured to control the set value of the random number range setting section 632 in accordance with, for example, the profit status of the gaming parlor. In the embodiment of the present invention shown in FIG. 1, when a specific ball detection signal is generated, the variable display device 301 continuously changes its display mode, and when the player presses the stop switch 202, the display mode of the variable display device 301 changes. It is designed to be fixed. Therefore, in this embodiment, the control unit 633 needs to know the timing of generation of the specific ball detection signal. Therefore, in this embodiment, the specific ball detection signal is added to the control unit 633 as an interrupt signal, and the control unit 633 uses this interrupt to generate the game parlor's profit that the difference calculation circuit 613 as a rewriting signal generating means derives to its output terminal. The number of balls is read and the set value of the random number range setting section 633 is rewritten in accordance with the number of profitable balls at the gaming parlor at that time. Here, Table 1 shows the correspondence between the number of profitable balls at the gaming parlor, the random number generation range, and the probability that the variable display device 301 will take a specific display mode of [7.7] when the random number generation range is within the random number generation range.

[Table] Next, the operation of this embodiment when a player plays a game using the pachinko game machine of this embodiment will be explained with reference to FIGS. 1 to 4. First, the player places the purchased pachinko balls into the supply tray 105 of any pachinko game machine, and then inserts them into the ball hitting device 1.
Hit one pachinko ball at 07. The pachinko balls hit in this way flow into the gaming section 102 along the guide rail 101,
It falls along the board surface of the gaming section 102. In this way, in the process of falling, some pachinko balls win a prize in some winning ball device, while others are collected into the out hole 104 without winning a prize. First, considering a pachinko ball that has won a prize in any winning ball device, this pachinko ball flows down along the winning ball collecting gutter 505 on the back side of the pachinko game machine 100, and enters the ball receiving box while turning on the winning ball detector 506. 507, and then collected by a collection device (not shown) located below the pachinko game machine 100. When this pachinko ball turns on the winning ball detector 506, the winning ball detection signal generated by the winning ball detector 506 is applied to the control system 600, and is also applied to the winning ball number setting device 503 and the winning ball ejecting device 504. A predetermined number of prize balls are then discharged from the prize ball ejecting device 504 to the supply tray 105 from the ball outlet 1051 via the prize ball ejecting path 508. still,
At this time, if the supply tray 105 is full, the prize balls are discharged into the tray 106 from the tray outlet 1061 via the branch channel 509. When the winning balls are paid back in this manner, the prize ball number setting device 503 supplies a predetermined number of prize balls from the tank chute 502 to the prize ball discharging device 504 again in preparation for the next winning ball detection. On the other hand, the pachinko balls that have flowed into the out hole 104 are once collected in the ball receiving box 507 and then collected in a collecting device (not shown). Therefore, all pachinko balls hit by players are stored in the ball receiving box 507, regardless of whether they are winning balls or out balls, so the hit ball detector 510 installed at the exit of this ball receiving box 507 detects the balls that are hit. The ball detection signal indicates the number of pachinko balls hit by the player. Therefore, the profit calculation means 610 in the control system 600 calculates the number of profit balls of the game parlor based on the winning ball detection signal and the hit ball detection signal, and derives this number of profit balls to the output line. The calculation formula for calculating the number of profit balls has already been shown, so a redundant explanation will be omitted. For example, if 15 prize balls are paid out for each winning ball, the multiplication rate setting device 612 is set to a value of [15], and the multiplication circuit 611 multiplies the number of winning balls by [15] to calculate the number of paid out balls, adds this to the subtraction terminal of the difference calculation circuit 613, and performs the difference calculation. The circuit 613 calculates a value by subtracting the number of returned balls added to the subtraction terminal from the number of batted balls added to the addition terminal, and the result of the subtraction is derived on the output line of the difference calculation circuit 613. Become. In the process of continuing the game in this way, the specific ball winning area 201 provided on the board of the gaming section 102
When a pachinko ball wins a prize, the specific ball detector 203 generates a specific ball detection signal, and this specific ball detection signal is applied to the control unit 633 as an interrupt signal. Then, due to this interrupt, the control unit 632 reads the information indicating the number of profitable balls of the pachinko gaming machine 100 derived from the output line of the difference calculation circuit 613, and sets the random number range setting unit 632 based on the above-mentioned Table 1. At the same time as rewriting the setting value, the random number generation unit 631 is activated. For example, if the number of profitable balls of the gaming machine is +1785, the control unit 6
33 writes [3] as the minimum value of the random number to the random number range setting section 632, and writes [3] as the maximum value of the random number.

[9] is written and the random number generation unit 631 is activated. As a result, the random number generator 631 starts from [3].

Generate random numbers in the range of [9] using software,
This random number is added to decoder drivers 621 and 622. In the illustrated embodiment of the present invention, two series of decoder drivers are prepared, so it goes without saying that the random number generation section 631 also independently generates two series of random numbers. The random numbers generated in this way are decoded by the decoder drivers 621 and 622, and the display mode of the variable display device 301 changes in accordance with the random numbers generated by the random number generator 631. When the player presses the stop switch 202 while the display mode of the variable display device 301 is changing in this way, the stop switch 2
The stop signal generated by 02 is applied to the control unit 633 as an interrupt signal. As a result, the control unit 633 stops the random number generation unit 631, and
The display determining means 624 is activated. First, when the random number generator 631 stops operating, the variable display device 301 fixes its display mode at that point. Further, when the display mode of the variable display device 301 is fixed in this way, the display determining means 624 is activated by the control unit 633 at this point, so it determines the display mode of the variable display device 301 at that point. Then, the opening time of the variable prize winning device 401 is controlled in accordance with the display mode at that time. In this embodiment, the variable display device 30
When the display mode of 1 is [7.7], the variable winning device 401 is opened for 20 seconds, and when the variable display device 301 is in any other display mode, the variable winning device 401 is opened.
Since it is opened for 0.6 seconds, display discrimination means 6
24, it is only necessary to be able to determine whether the display mode of the variable display device 301 is [7.7] or something else. is the set value (in this case, the set value is [7]), and the other input is the output of the random number generator 631.It is easy to use an array of exclusive OR gates or equivalent logic. It will be composed of The determination result by the display determination means 624 is applied to the variable winning device drive control means 625, and the variable winning device drive control means 625 sends a drive current to the solenoid 626 according to the determination result. In this way, the winning probability for the time that the variable winning device 401 is operating is improved, so that the profits of the players are increased. In addition, in the current operation example, the random number generator 631 has a minimum value of [3] and a maximum value of

Since a random number of [9] is generated, the probability that the display mode becomes [7.7] when the variable display device 301 stops is 1/49, as shown in Table 1 above. The probability of a so-called jackpot occurring is relatively high. However, suppose that the profit rate of the gaming parlor has decreased due to some factor, and the number of profitable balls of the gaming parlor is -2751, for example, at the time when the specific ball detection signal is generated. In such a case, the control unit 633
receives the specific ball detection signal as an interrupt signal, and when the number of profit balls is read from the difference calculation circuit 613, the random number range setting unit 6 sets the number of profit balls corresponding to the number of profit balls.
As the lowest random number for 32

[0] is also the maximum value of random numbers

Set [9]. Therefore, the random number generator 631

From [0]

Since a random number [9] is generated and the display mode of the variable display device 301 is determined in accordance with this random number, the probability that the so-called jackpot display mode of [7.7] will occur when the player presses the stop switch 202 is It becomes 1/100,
The probability is lower than in the above case. According to this embodiment, if the profit rate of the gaming parlor is decreasing due to some factor, the probability that a so-called jackpot will occur when a slot game is played due to winning in the specific ball winning area 201 is increased. As the percentage decreases, it becomes easier to ensure the profitability of the gaming parlor, and conversely, if the profitability of the gaming parlor increases due to some factor, the specific ball winning area 20
1 increases the probability that a so-called jackpot will occur when a slot game is played, making it easier to return an appropriate number of prize balls to the player. Therefore, according to this embodiment, even if the nail adjustment is somewhat insufficient, it is possible to set the platform in a well-balanced manner as a whole. In particular, if the table that regulates the correspondence between the number of profit balls and the random number setting range shown in Table 1 above is made variable by program, the so-called collection table, service table,
It will be easier to properly set up play tables and the like without relying on nail adjustments. Next, FIG. 5 is a block diagram showing another embodiment of the control system. In summary, the embodiment of FIG.
As shown in FIG. 1, a pachinko game machine 1 in which a variable display device 301 is activated when a winning ball enters a specific ball winning area, and then the variable display device 301 is stopped when the player presses a stop switch 202.
00 control, but the embodiment shown in FIG. 5 differs from this in that the variable display device 301 is constantly updated from the time the power is turned on, and its display mode is fixed by winning a prize in the specific ball winning area 201. This shows a control system for controlling a pachinko game machine. That is, in the case of the pachinko gaming machine 100 in which the variable display device 301 is activated by winning a prize in the specific ball winning area 201 as described above, and then the variable display device 301 is stopped by the player pressing the stop switch 202. , variable display device 301
Since the display mode is changed after the specific ball detection signal is generated, it was possible to wait for the specific ball detection signal to set the random number generation range or set the preset value, but the variable display device 301 In the case of an embodiment in which the display mode is constantly updated from the time the power is turned on, and the update is stopped upon generation of a specific ball detection signal, it is not possible to wait for the generation of the specific ball detection signal to set the random number generation range, etc. Therefore, in the embodiment shown in FIG.
30 is provided with a timer 639, and this timer 639 periodically generates an interrupt signal to control the control unit 6.
33 reads the number of profit balls of the gaming parlor calculated by the profit calculation means 610, and sets a random number generation range in the random number range setting section 632 according to the number of profit balls according to Table 1 above. Therefore, in the embodiment of FIG.
At the timing of the interrupt that occurs periodically, the set value of the random number range setting section 632 is rewritten in accordance with the number of profitable balls at the gaming parlor. In the embodiment of FIG. 6, the specific ball detection signal generated by the specific ball detector 203 has the same function as the stop signal generated by the stop switch 202 in the embodiment of FIG. The random number generator 631 fixes its output, and
The display determining means 624 determines the display mode of the variable display device 301 at that time. In the above description, in order to facilitate understanding of the present invention, a very simple example of the profit giving means is used, that is, a slot game that is equipped with a variable display device and a variable prize winning device, and in which the result of a slot game that appears on the variable display device is I showed an example where the variable winning device is opened for 20 seconds when there is a jackpot, and the variable winning device is opened for 0.6 seconds when the game result is other than that.
The profit giving means is not limited to this, but includes various similar game devices and others. For example, other game devices include those described above with other components added, for example, a specific winning area within the variable winning device while the variable winning device is open for 20 seconds in the same manner as above. When a pachinko ball wins a prize, the variable prize winning device is activated, for example.
It may be opened for 20 seconds, or the variable display panel may have three or four digits. Note that the configuration and function of the profit giving means 620 are different,
If the profit given to the player differs when a certain gaming state occurs, the contents of the probability control table corresponding to the number of profit balls shown in Tables 1 and 2 above are rewritten accordingly. It goes without saying that it should be done. Furthermore, in the above example, the profit calculation means calculates the profit status of the gaming parlor based on the number of batted balls and the number of winning balls, but the information collected by the profit calculation means is not limited to this, for example, , the profit may be calculated based on the number of balls supplied to the pachinko game machine, etc. Particularly in the current situation where the centralized management of game parlors has progressed in recent years, the information that should be collected will differ depending on the configuration of the central management system. All you need to do is monitor the profit status of the gaming parlor based on such information. Additionally, although the above example shows an example in which the control system is provided for each pachinko game machine, it is not necessary to provide the control system for each pachinko game machine, especially in the case of game parlors etc. that have introduced a centralized management system. Alternatively, various information may be adjusted in a central control room, and the control information may be transmitted to each pachinko game machine in real time to control the payout rate. Although the present invention has been described above with reference to the illustrated embodiments, the present invention is not limited to the above-described embodiments, and can be freely modified and implemented within the scope of the configuration described in the claims. It is something. "Effect" As explained above, according to the present invention, the numerical range of the random number is variably set based on the content of the rewriting signal corresponding to the profit status etc., and the random number of the variable display device provided in each pachinko game machine is Since it is possible to convert and control the probability value in the control, the probability value in the random number control is not fixed to a constant value as in conventional pachinko gaming machines, but can be changed to a rewriting signal that is generated in response to the progress of the game. It becomes possible to control conversion based on the contents of Therefore, it is possible to set the pachinko game machine to an appropriate target profit state for the game parlor without relying on nail adjustments that require a high degree of skill and intuition of the operator. Further, according to the present invention, compared to, for example, a case where the display areas that can be displayed by the variable display device are limited to a few specific items, the player can easily change the display content during conversion drive of the variable display device. As in the case where the variable display device becomes difficult to visually recognize and limits the display areas that can be displayed to a few specific items, there is absolutely no way that a jackpot will occur with the way the variable display device moves. There is no need to give the player a sense of distrust, such as making him or her think that the player is losing his or her feelings. Furthermore, since it is possible to obtain a predetermined probability value by rewriting the numerical data range of random numbers, the probability value conversion mode can be set in a variety of ways and freely, and its application range is wide and practical control can be easily performed. I can do it.
