Description

[Detailed description of the invention] [Industrial application field]

The present invention relates to a pachinko gaming machine equipped with a so-called electric accessory, and more specifically, in a pachinko gaming machine in which a player's profits are greatly improved when the electric accessory enters a predetermined gaming state, the frequency at which the electric accessory enters the predetermined gaming state is improved. This invention relates to a pachinko game machine that can be set in advance.

[Conventional technology]

Generally, pachinko gaming machines that use pachinko balls to play games have become popular and are widely popular as one of the convenient cash registers. As is well known, pachinko machines have multiple winning holes on the board, and when a player hits a purchased pachinko ball along the board, there is a certain probability that the pachinko ball will land in the winning hole. The number of prize balls will be refunded. In such pachinko machines, the only operation required by the player is to place the purchased pachinko balls into the supply tray and hit the ball with the ball hitting handle, which tends to make the game more monotonous and makes it difficult to collect a large number of prize balls. A high degree of skill is required to obtain such prize balls, and it is generally extremely rare for a player to obtain a large number of prize balls. Therefore, various electric accessories have been developed in order to change the game content and improve the service. In general, pachinko machines equipped with electric accessories have a relatively low occurrence rate, but they have a common feature of rapidly increasing winning rates in certain gaming conditions, so even less skilled players can They have the opportunity to win prize balls and have gained the support of many players. By the way, as mentioned above, in the case of pachinko gaming machines equipped with electric accessories, the winning rate increases rapidly when a specific gaming state occurs, so how often that specific gaming state occurs depends on the game. It is not hard to imagine that this would be a common concern for both customers and amusement arcades. For example, if the frequency of occurrence is too low, the interest of players will be diminished and the service will deteriorate; if the frequency of occurrence is too high, the management of the game parlor will be unsustainable. Therefore, as an amusement arcade, by adjusting the nails every day,
It is possible to provide services to players, and
The frequency of occurrence of the above-mentioned specific gaming state is set within the range in which a certain level of profit can be obtained.

[Problems to be solved by the invention]

However, factors related to the frequency of occurrence of this specific game state include the characteristics inherent to the electric accessory, the hardness and slope of the game board, the hardness and arrangement form of the obstacle nails, etc.
Due to the wide variety of weather conditions such as humidity and temperature, it must be said that it is impossible to make complete adjustments by adjusting the nails alone.

[Means to solve the problem]

The present invention has been made in view of the current situation, and its purpose is to provide a novel system that can accurately set the frequency with which an electric accessory enters a specific gaming state that is advantageous to the player. Our goal is to provide a pachinko game machine with the highest quality. In summary, the pachinko game machine of the present invention forces the electric accessory to enter a specific gaming state when it does not enter a specific gaming state even after being activated a predetermined number of times, and vice versa. If a specific gaming state occurs a predetermined number of times or more during business hours, the occurrence of the specific gaming state is forcibly avoided from then on.

【Example】

The more specific structure and operation of the present invention described above will become clearer from the Examples of the present invention described below. FIG. 1 is an external view of a pachinko game machine 100 showing an embodiment of the present invention. In the game section 102 surrounded by the guide rail 101 of the pachinko game machine 100 of this embodiment, examples of winning areas include a top winning hole 103, winning jacks 104a, 104b, specific ball winning areas 120a, 120b, 120c, and variable winning areas. A device 130 is provided, as well as an out hole 105 for collecting pachinko balls that have not won in any of the winning areas. Further, below these, there is a supply tray 150 that sequentially guides pachinko balls purchased by the player to the hitting position and refunds prize balls, and a receiver tray 16 that refunds surplus prize balls that cannot be refunded to the supply tray 150.
0, a speaker 171 for generating sound effects, a batting ball 181 for hitting pachinko balls as a ball hitting device 180, and a batting switch 1 for generating a batting command.
82, a ball-hitting handle 183 for adjusting the strength of the ball is provided. Further, a variable display device 110, which is one of the features of the present invention, is provided in the center of the gaming section 102, and the display mode of this variable display device 110 (in this specification, the display mode refers to the display mode provided in the variable display device 110). The opening mode of the variable winning device 130 (in this specification, the opening mode refers to the opening method of the variable winning device, such as the opening time and the number of openings) ) is determined. FIG. 2A shows an example of this variable display device 110, in which a hole formed in a substrate 111 has three-digit 7-segment LED displays 112a, 112b,
112c is provided, and above the board 111 is provided an armor portion 113 that distributes falling pachinko balls. The variable display device 110 shown in FIG. 2A is an application of a so-called slot game to a pachinko game machine, and its display mode is updated at high speed when a ball hits any of the predetermined winning areas 120a, 120b, and 120c. , the player presses the stop switch 14
When you press 1, the update is stopped and the slot game ends. The opening mode of the variable winning device is determined by the display mode of the variable display device at the end of the slot game. For example, in the example shown in FIG. 2A, when the display mode of the variable display device 110 becomes [7.7.7] and the slot game ends, the variable winning device 130 is opened for 30 seconds,
When the slot game ends in any other display mode, the variable winning device 130 is opened for 0.6 seconds. Further, in this embodiment, the variable winning device 130a is defined as a special ball winning area, and the variable winning device 130a is defined as a special ball winning area.
If a prize is won in the variable winning device 130a when 0 is in the opening mode for 30 seconds, after the above 30 seconds opening time has elapsed and the variable winning device 130 is opened, the variable winning device 130 will be opened again for 30 seconds. . Details regarding the variable winning device 130 will be described later, but to summarize, the variable winning device 130 is a winning device configured such that when opened, the internal winning rate increases, and when activated, the internal winning rate decreases. It is a ball device. Therefore, the fact that the display mode of the variable display device 110 becomes [7.7.7] means that the variable winning device 13
30 of the variable winning device 130 due to the fact that 0 is opened for 30 seconds and the winning to the variable winning device 130a.
If you consider that you can repeat the opening of seconds, it will bring about a rapid improvement in the winning rate.
How often is the variable display device 11 displayed during business hours?
Whether the display mode of 0 becomes [7.7.7] is a matter of great concern to both players and gaming parlors. In order to provide a satisfactory service to the players and also increase a certain level of profit for the gaming parlor, the desired frequency is determined by the type of individual pachinko gaming machines, such as the number of prize balls for winning balls and the mode of the variable winning device. Although the specific values differ depending on the characteristics and characteristics, a certain value has been determined from experience, and it is desirable that the specific display mode [7.7.7] occur at a frequency close to that value. Factors related to the frequency with which the variable display device 110 adopts the specific display mode [7.7.7] can be roughly divided into:
It can be divided into the inherent probability of the variable display device 110 itself and the winning rate in the specific ball winning areas 120a, 120b, and 120c. Therefore, first, the inherent probability of the variable display device 110 will be considered. Since the prince mode of the variable display device 110 is determined by the combination of display contents of the three-digit displays 112a, 112b, and 112c, each display 112
If a, 112b, 112c can take on 10 types of numerical values from "0" to "9", the probability that the display mode will be [7.7.7] is 1/1000, and each display 112a, 112b , 112c obtains only odd numbers from 1 to 9, the probability that the display mode becomes [7.7.7] is 1/125. However, this probability of 1/1000 or 1/125 is the probability obtained when the number of trials is repeated infinitely, and it is the probability that is obtained when one player is playing the game or a short period of one day's business hours. If you look at it, this probability will have a considerable deviation. Therefore, in this embodiment, in order to provide uniform service to more players, the variable display device 1
If the specific display mode [7.7.7] does not occur even once during the predetermined number of operations of the variable display device 110, the variable display device 110 is forced to change to the specific display mode [7.7.7]. Next, specific ball winning areas 120a, 120b, 1
Considering the winning rate for 20c, this winning rate depends on fixed factors such as the hardness of the plywood board that makes up the game section 102, the arrangement and hardness of the obstacle nails, the installation slope of the stand, and the adjustment of the nails, and the prize balls in the upper tank. It also changes depending on fluid factors such as the number, temperature, humidity, polishing of the balls, and degree of dryness. Therefore, for example, the plywood may become loose due to an increase in humidity, causing the specific ball winning area 1 to become loose.
When the winning rate for 20a, 120b, and 120c increases, the variable display device 110 within one business hour
The number of times that a specific display mode of [7.7.7] is displayed increases, which hinders the business of the game parlor. Therefore, in this embodiment, if the variable display device 110 has changed to the specific display mode [7.7.7] a predetermined number of times, the variable display device 110 will change to the specific display mode [7.7.7] from then on.
The specific display mode is forcibly avoided. Further, FIG. 2B shows another embodiment of the variable display device 110, in which a peripheral frame 142 is provided with a fastener 115 for screwing the variable display device 110 to the gaming section 102, and A 7-segment LED display 116 is provided in the center,

b, 120c, the display contents of the display 116 are updated, and the inner lamp display section 1
17 and the lamps in the transparent windows of the outer lamp display section 118 are turned on sequentially clockwise or counterclockwise, and when the stop switch is pressed, the display contents of the display 116 as well as the inner lamp display section 117 and the outer lamp display section are turned on. The lighting position of 118 is fixed. At this time, the display on the display 116 and the inner lamp display section 1
17 and the lighting position of the outer peripheral lamp display section 118 becomes a display mode, and the opening mode of the variable winning device is determined in accordance with this display mode. FIG. 3 is a sectional view of a specific ball winning area 120a that is involved in the operation of the variable display device 110, and the specific ball winning area 120a basically pays out a predetermined number of prize balls for winning inside. It is a hole. Therefore, the winning jack 121a attached to the gaming section 102 has a ball outlet 1 that passes through the gaming section 102.
22a communicates with the winning ball collecting gutter 201, and the pachinko balls that have flowed into the winning ball collecting gutter 121a are transferred to the winning ball collecting gutter 201 via the ball outlet 122a.
As a result, a predetermined number of prize balls are paid out. The specific ball winning area 120a is different from a normal winning hole in that the variable display device 110 starts operating when a prize is won in the specific ball winning area 120a. A specific ball detector 123ak is provided to detect winning balls. The specific ball detector 123a may have any structure as long as it can reliably detect winning balls entering the specific ball winning area 120a, but specifically, a micro switch, an optical sensor, etc. may be used. A specific ball detection signal outputted by the specific ball detector 123a when winning the specific ball winning area 120a is applied to the control system described later, and the variable display device 110 starts operating based on this signal. Incidentally, since the basic function of the specific ball winning areas 120b and 120c is the same as that of the specific ball winning area 120a, a duplicate explanation will be avoided. Next, FIG. 4A is a sectional view showing an example of a variable prize winning device 130 whose opening mode is controlled in accordance with the display mode of the variable display device 110. The variable prize winning device 130 shown in FIG. 4A is a so-called tulip, and the petals 131 of the tulip are supported by a support shaft 132 on a board 133a, and the board 133a is fixed to the board of the gaming section 102. Ru. In addition, petals 13 are placed on the board of the gaming section 102.
A ball outlet 134 is formed at a location corresponding to the back side of 1, and pachinko balls that flow into the petal 131 when the petal 131 is opened flow into the winning ball collection gutter 201 via the ball outlet 134, and are collected as prize balls. A refund will be made. Further, a drive mechanism for opening and closing the petals 131 is provided on the back side of the gaming section 102 and inside the ball outlet 134. Specifically, a pin 136 that is integrally molded or fixed to the petal 131 passes through a half-moon-shaped hole 135 formed in the substrate 133a and connects to the ball outlet 134.

Furthermore, a solenoid 304 is provided on the back side of the gaming section 102, and a gripping part 306 for gripping the receiving piece 303 is formed at the tip of an operating rod 305 of the solenoid 304. In the operation of the variable winning device 130, the solenoid 304 is deenergized in the initial state, and the receiving piece 3
03 is pulled up by the operating rod 305, the operating rod 302 pushes down the pin 136, and therefore,
Petals 131 are closed. On the other hand, when the solenoid 304 is energized in accordance with the display mode of the variable display device 110, the receiving piece 303
is pushed down by the operating rod 305, so the operating rod 302 pushes up the pin 136, and as a result, the petal 131 is opened. Therefore, solenoid 30
By controlling the energizing time of No. 4, the opening time of the variable prize winning device 130 can be controlled. In this embodiment, as shown in FIG.
Three variable prize winning devices 130 are arranged within the interior, and each variable winning device 130a, 130b, 130
The basic structure of c is the same, but the only difference is that the variable winning device 130a also serves as a special ball winning area. Therefore, a special ball detector 401 is provided in the variable winning device 130a to detect winning balls entering the inside. The special ball detection signal generated by the special ball detector 401 motivates the variable winning device 130 to repeat the opening for 30 seconds. In addition, the special sphere detector 40
1 is specifically composed of an optical sensor, a micro switch, and the like. FIG. 4B shows another embodiment of the variable winning device 130', and since this variable winning device 130' is relatively large, one piece is provided in the gaming section 102. The variable prize winning device 130' shown in FIG. 4B is constructed as follows and operates as follows. First, a door 138 is rotatably supported on the lower side of a rectangular base frame 137, and the base frame 137 is connected to the gaming section 102.

Further, a receiving piece 139 is fixed or integrally molded at the lower right end of the door 138 at substantially right angles to the door 138, and a long hole is formed in the receiving piece 139 over substantially its entire length. A hook-shaped rod 307 is engaged with the elongated hole of the receiving piece 139, and a solenoid 304 is connected to the other end of the rod 307. It's being stretched. Therefore, when the solenoid 304 is deenergized, the receiving piece 139 is pulled down by the coil spring 308 via the rod 307, and the door 138 is pulled down.
is closed as shown by the solid line in FIG. 4B. Also, when the solenoid 304 is energized, the receiving piece 1
39 is pulled upward by the solenoid 304 via the rod 307, and the door 138 is lifted upward by the solenoid 304 via the rod 307.
It is opened as shown by the two-dot chain line. Therefore, the variable prize winning device 130' of FIG. 4B also
By controlling the energization time of the solenoid 304, its opening time can be controlled. Furthermore, the inside of the variable winning device 130' is divided into three winning areas, with a special ball winning area 402 in the center and a general winning area 104 on both sides.
c, 104d. Therefore, a special ball detector 401 is provided within the special ball winning area 402 to detect winnings inside. The special ball detection signal output by the special ball detector 401 motivates the variable prize winning device 130' to repeat the opening for 30 seconds. Next, FIG. 5 is a mechanical diagram of the prize ball ejection system on the back side of the pachinko game machine 100. Prize ball ejection device 2
A predetermined number (for example,
15) prizes are supplied and held, and each time a pachinko ball wins, the prize balls held in the tamazaya 204 are refunded to the player. That is, on the back side of the pachinko gaming machine 100, there are provided a winning hole 103, winning jacks 104a, 104b, specific ball winning areas 120a, 120b, 120c, and a winning ball collecting gutter 201 that collects winning pachinko balls from the variable winning device 130. Pachinko balls that have won in the various winning areas described above flow into the ball controller 205 via the winning ball collecting gutter 201, and the ball controller 205 is rotated clockwise. the result,
The left end of this ball controller 205 is engaged with a hook-shaped portion 208 of a locking rod 207 to prevent two or more winning balls from flowing into the ball controller 205 in succession. On the other hand, a lead-out path 209 is provided below in the direction of rotation of the ball controller 205, and the pachinko balls that have been rotated by the ball controller 205 flow down the lead-out path 209 and land on the receiving tray 211 of the crank squid 210. get on.
The crank anchor 210 supported by the spindle 212 is used to lock the ball control lever 214 with an engaging pawl 213, but when a pachinko ball is placed on the tray 211, the crank anchor 210 is rotated by its own weight.
rotates clockwise around the support shaft 212 to release the lock of the ball control lever 214 and release the saucer 21.
The pachinko ball above 1 falls naturally. There is a tray 215 provided at one end of the ball control lever 214 below in the direction in which the pachinko balls fall, and the pachinko balls that have fallen from the tray 211 ride on the tray 215. At this time, the ball control lever 214
is unlocked, so the ball control lever 214 rotates clockwise around the spindle 216 due to the weight of the pachinko ball on the tray 215, pushing up the continuous rod 217, and this pachinko ball is lying. It falls into the discoverer 218. Furthermore, a lever rod 21 is attached to the upper end of the connecting rod 217.
9 is connected, and a beaded lever 220 is connected to the other end of the lever lever 219, and when the connecting rod 217 is pushed up, the lever lever 21
9 rotates clockwise around the support shaft 221 and pushes down the left end of the beaded lever 220. the result,
The ball shaft 204 rotates counterclockwise around the spindle 203, and the prize ball held in the ball shaft 204 passes through the prize ball outlet path 222 and reaches the prize ball outlet 1.
51 and is returned to the supply tray 150. Also, if the supply tray 150 is full at this time, the prize ball will be sent to the diversion gutter 2.
23 and is returned to the tray 160 from the tray outlet 161. In addition, a locking rod 207 is provided in the prize ball outlet path 222.
A treadle lever 224 is provided to lift the prize ball, and when the prize ball falls within the prize ball lead-out path 222,
The weight pushes down the treadle lever 224, and the engagement between the locking rod 207 and the ball controller 205 is released. As a result, the ball controller 205 rotates counterclockwise around the support shaft 206 under its own weight and returns to its initial state. On the other hand, as the pachinko ball on the tray 215 falls into the lie detector 218, the ball control lever 214 rotates counterclockwise by its own weight around the support shaft 216, and is locked by the crankshaft 210. Ru. The movement of this ball control lever 214 is transmitted to the ball shear lever 220 via the connecting rod 217 and lever lever 219, and
20 pulls up the ball sheath 204 and returns the ball sheath 204 to its initial state. Incidentally, the lie detector 218 is used to confirm the authenticity of a complaint from a player that the prize balls have not been refunded. That is, the elevating lever 225 that opens and closes the exit of the lie detector 218 is the treadle lever 2.
24, and when the treadle lever 224 is pushed down by the prize ball, the elevating lever 225 rises and opens the exit of the lie detector 218.
Therefore, if a pachinko ball remains in the lie detector 218, it can be known that the prize ball has not been paid out. Further, on the back side of the pachinko gaming machine 100, although not shown in FIG. 5 because the specific positional relationship thereof is not particularly limited, there is electrical control for driving and controlling the variable display device 110 and the variable prize winning device 130.

to fall. In this way, in the process of falling along the gaming section 102, some of the pachinko balls enter a winning hole, and others are collected into the out hole 105 without winning. In addition, since the variable winning device 130 is closed in the initial state, no pachinko balls will be won in these. Pachinko balls that have entered any of the winning holes are sent to the ball controller 205 via the winning ball collection gutter 201 on the back side of the pachinko game machine 100 (see FIG. 5).
The balls flow in one after another and drop into the lie detector 218 via the outlet path 209 while rotating the ball control lever 214 clockwise. This ball control lever 214
The movement is transmitted to the bead 204 via the connecting rod 217, the lever 219, and the bead lever 220, causing the bead 204 to rotate counterclockwise. As a result, the prize balls held in the balls 204 are transferred to the prize ball outlet 1 via the prize ball outlet path 222.
51 to the supply tray 150, and if the supply tray 150 is full at this time, the prize ball is returned to the distribution gutter 223.
It is returned to the tray 160 via the tray outlet 161. Moreover, the pachinko balls collected in the out hole 105 become a profit for the game parlor. In the process of continuing the game in this way, the pachinko balls are placed in specific ball winning areas 120a, 120b, 120.
When a pachinko ball wins in any of the pachinko balls, the specific ball detector in the specific ball winning area 120 in which the pachinko ball has won generates a specific ball detection signal. For example, specific ball winning area 12
If a pachinko ball has won at 0a, the specific ball detector 123a generates a specific ball detection signal, and this specific ball detection signal is added to the AND gate G1. At this time, the overflow output from the up-down counter 501 is applied to the control terminal G1 of the AND gate G1, but this up-down counter 501 is for receiving up to four specific ball detection signals as described later. Therefore, at this point, the level of the control terminal G1 is H, and therefore, the specific ball detection signal is transmitted to the up-down counter 501 via the AND gate G1.
Incidentally, to add an explanation regarding the up-down counter 501, the up-down counter 501 is used to prevent the game from becoming monotonous due to too many consecutive slot games. Therefore, in this embodiment, the up-down counter 501 counts up using the specific ball detection signal as a clock, and at the fourth count, an overflow signal causes the control terminal C1 of the AND gate G1 to go low.
In addition to blocking the specific ball detection signal from then on, a countdown starts when the slot game is completed once. When the up-down counter 501 counts up due to the specific ball detection signal, its Q output becomes H, and the generation of the special ball detection signal is controlled by the AND gate G2.
tell. In addition, in the drawing, up-down counter 5
Although the Q output of 01 is shown as one, since the up-down counter 501 overflows at the fourth count, in reality there are two Q outputs.
The logical sum of the binary outputs of the books will be added to AND gate G2. On the other hand, the output of the flip-flop 502 is applied to the control terminal C2 of the AND gate G2, but the flip-flop 502 is reset in the initial state, so the level of the control terminal C2 is H, and the specific ball detection signal is is and gate G2
is transmitted to the flip-flop 502 via
Flip-flop 502 stores the occurrence of a specific ball detection signal. Also, at this time, the flip-flop 502
At the same time as is set, AND gate G2 closes to prevent the specific ball detection signal from being applied to flip-flop 502 any further. In this way, when the specific ball detection signal is stored in the flip-flop 502, the flip-flop 502
The counter drive circuit 503 is activated at the rising edge of the Q output of 02, and the gate signals g3, g4, g
Raise 5 all at once to H level and gate G
Open 3, G4, and G5 all at once. The other inputs of these AND gates G3, G4, G5 each have an oscillator 5.
The output terminals of the oscillators 504a, 504b, 504c are connected to each other.
4c is constantly oscillating from the time the power is turned on. Therefore, the counter drive circuit 503 receives the gate signals g3,
At the same time as g4 and g5 are started up, the oscillation frequencies of the corresponding oscillators 504a, 504b, and 504c are applied to each of the preset counters 505a, 505b, and 505c.
a, 505b, 505c are the corresponding oscillators 504
It is updated in synchronization with the oscillation frequency of a, 504b, and 504c. These preset counters 505a, 505b,
The calculated value of 505c is sent to the corresponding decoder 506a,
506b, 506c and the corresponding displays 112a, 112 of the variable display device 110
b, 112c. Therefore, the display 11
The display contents of 2a, 112b, and 112c are also changed by the corresponding oscillator 504 at the same time that the counter drive circuit 503 raises the gate signals g3, g4, and g5.
It is updated in synchronization with the oscillation frequencies of a, 504b, and 504c. At this time, each oscillator 5 may be
If the oscillation frequencies of 04a, 504b, and 504c are different, each display 112a, 112b,
The update timing of 112c will be different for each digit, and the slot game will become more varied. Furthermore, since the gate signal g5 output from the counter drive circuit 503 is also applied to the AND gate G28, the display devices 112a, 112b, 112
When the display contents of c are being updated, the AND gate G28 is opened, the sound effect signal generated by the sound effect generating means 172 is amplified by the amplifier 175 via the AND gate G28, and the slot game is started. The sound effect that indicates what happened is on speaker 17.
Generated from 1. In this way, any particular ball winning area 120
When the player presses the stop switch 141 at any timing after the slot game starts due to winnings in slots a, 120b, and 120c, a stop signal is output from the stop switch 141 at that timing, and this stop signal is sent to the counter via the OR gate G3. It is added to the drive circuit 503. When this stop signal is applied, the counter drive circuit 503 lowers the gate signals g3, g4, and g5, and closes the AND gates G4, G5, and G6.
As a result, preset counters 505a, 505
Since the clock is no longer applied to the preset counters 505a, 505b, 505c,
The count value of 05c is the corresponding gate signal g3, g
4, g5 is stopped at the falling edge of , and the display contents of the corresponding displays 112a, 112b, 112c are also stopped at that point. If necessary, if the counter drive circuit 503 lowers the gate signals g3, g4, and g5 at different timings, the result of the slot game will change, making the game more interesting. For example, when the stop signal is generated, the counter drive circuit 503 first lowers the gate signal g3, and then sequentially lowers the gate signals g4 and g5 at a predetermined interval.
The game results will appear in the order of b, 112c. Further, in this embodiment, the stop means 140 includes a timer 142 and a differential circuit 143 for ending the slot game when the player forgets to press the stop switch 141. That is, timer 142
The output of AND gate G2 is added to
When the output of the AND gate G2 falls due to the specific ball detection signal, the timer 142 oscillates using the falling edge as a trigger, and the timer 142 oscillates for a predetermined period of time (for example, 4
sec) Set the output to H level. The output of this timer 142 is applied to a differentiating circuit 143, and the differentiating circuit 143 generates a differential pulse at the falling edge of the output of the timer 142, and this differential pulse is sent to the counter drive circuit via an OR gate G3. 503 as a stop signal. Therefore, according to this embodiment, even if the player forgets to press the stop switch 141, the slot game will automatically end 4 seconds after the start of the slot game. Since the gate signal g5 falls at the same time as the slot game ends, the AND gate G28 also closes, and the sound effect indicating that the slot game is being played also stops. When the slot game ends in this way, the variable winning device drive control means 600 controls the variable winning device 1 according to the display mode of the variable display device 110 at the time of ending.
Controls 30 opening modes. That is, the determination circuit 601 in the variable prize winning device drive control means 600 includes a preset counter 505a,
The coefficient values of 505b and 505c are given,
The determination circuit 601 determines the display mode of the variable display device 110 based on the calculated values of the preset counters 505a, 505b, and 505c at the end of the slot game, and controls the opening mode of the variable winning device 130 based on the determination result. Specifically, the discrimination circuit 601 is configured with AND logic, and includes preset counters 505a and 50.
When the calculated values of 5b and 505c are all "7", the output is set to H level. Therefore, when the display mode of the variable display device 110 becomes [7.7.7] and the slot game ends, the AND gate G9 opens, and when the display mode of the variable display device 110 changes to [7.7.7] and the slot game ends, the AND gate G8 opens. . When the game signal g5 falls simultaneously with the end of the slot game, the differentiating circuit 602 generates a differentiating pulse at the falling edge. Therefore, if the slot game has ended in the display mode [7.7.7], a differential pulse is applied to the timer 604 via the AND gate G9, and the driver 6 is activated for the 30 seconds set by the timer 604.
Since the drive current flows through solenoid 30
4a, 304b, and 304c are energized for 30 seconds, and the variable prize winning device 130 is opened for 30 seconds. If the slot game is finished in a display mode other than the above, a differential pulse is applied to the timer 603 via the AND gate G8, and the driver 605 outputs the 0.6 second period set by the timer 603.
Since a driving current flows through the variable prize winning device 130,
Open for 0.6 seconds. Also, at this time, the outputs of the timers 603 and 604 are applied to the AND gates G26 and G27, respectively, so when the variable winning device 130 is open for 0.6 seconds, the sound effect signal output by the sound effect generating means 173 is Also, when the variable winning device 130 is open for 30 seconds, the sound effect signal outputted by the sound effect generating means 174 is sent to the amplifier 1 via the AND gate G26.
75 and output from the speaker 171. When the variable prize winning device 130 is in the opening mode for 0.6 seconds, the differential pulse generated by the differentiating circuit 606 at the falling edge of the output of the timer 603 is passed through the OR gate G11 to the countdown input terminal of the up/down counter 501. It is applied to the reset input terminal of the flip-flop 502 to count down the up-down counter 501, reset the flip-flop 502, and permit the reception of the specific ball detection signal again. Further, when the variable winning device 130 enters the 30 second opening mode, the variable winning device 130 repeats the 30 second opening mode based on the generation of the special ball detection signal, as described below. That is, in this embodiment, the variable winning device 130a also serves as a special ball winning area, and the variable winning device 130a also serves as a special ball winning area.
When a pachinko ball wins a, the special ball detector 401
generates a special ball detection signal, which is applied to AND gate G12 in continuation control means 700. The outputs of the timer 604 and counter 705 are applied to the control terminals C3 and C4 of the AND gate G12, respectively, but when the variable prize winning device 130 is in the open state for 30 seconds, the output of the timer 604 is of course at H level. Further, the counter 705 is used to restrict the opening mode from continuing for 30 seconds or more a predetermined number of times (10 times in this embodiment), and since the output of the counter 705 is at H level in the initial state, AND gate G12 is open and the special sphere detection signal is applied to the set input terminal of flip-flop 701 via AND gate G12. As a result, flip-flop 701 is set and stores the occurrence of the special ball detection signal. When the generation of the special ball detection signal is stored in this way, the Q output of flip-flop 701 goes to H level and AND gate G13 opens, and the output of flip-flop 701 goes to L level and AND gate G14 closes. . When the variable prize winning device 130 is closed after a period of 30 seconds has elapsed, the output of the timer 604 also falls to the L level, and the differentiating circuit 702 generates a differentiating pulse at the falling edge. This differential pulse is applied to a timer 703, which oscillates for a predetermined period of time (for example, 2 seconds) using this differential pulse as a trigger, and the differential circuit 704 outputs a differential pulse at the falling edge of the output of the timer 703. At this time, flip-flop 701 is set, so this differential pulse is applied to AND gate G1.
3. Added to timer 604 via OR gate G29. Therefore, the timer 604 oscillates again, and the variable prize winning device 130 repeats the opening for 30 seconds again. Thereafter, in the same manner, every time a pachinko ball enters the variable winning device 130a when the variable winning device 130 is in the opening mode for 30 seconds, the variable winning device 130 repeats the opening for 30 seconds. At this time, the counter 705 counts the falling edges of the output of the timer 604, and when the opening of the variable prize winning device 130 for 30 seconds is repeated 10 times, the control terminal C4 of the AND gate G12
Lower the level to L level, and gate G
Close 12. Therefore, from then on, the variable prize winning device 130
Even if a pachinko ball wins in a (that is, in the special ball winning area), the special ball detection signal is sent to the flip-flop 7.
01 is not accepted. Therefore, since the flip-flop 701 is not set, the differential pulse output from the differentiating circuit 704 after the tenth 30-second opening of the variable winning device 130 is completed and the time set by the timer 703 has elapsed will be outputted from the differentiating circuit 704 by the AND gate G14. - It is added to the countdown input terminal of the up-down counter 501 and the reset input terminal of the flip-flop 502 via the OR gate G11, allowing reception of a new specific ball detection signal. Further, at this time, the output of the OR gate G11 is applied to the clear input terminal of the counter 705, and the entire continuation control means 700 is initialized. Also, when the variable winning device 130 is in the opening mode for 30 seconds and no pachinko ball enters the variable winning device 130a, the flip-flop 701 is not set, so the differential pulse generated by the differentiating circuit 704 is generated by the AND gate G14 and the OR gate G11. The counter 705 is initialized via the up/down counter 501, and the flip-flop 502 is reset to allow reception of a new special ball detection signal. Note that even when the variable winning device 130 is in the winning mode for 0.6 seconds, a prize may be won in the variable winning device 130a, but when the variable winning device 130 is in the winning mode for 0.6 seconds, the output of the timer 604 is at L level. Since AND gate G12 is closed, flip-flop 701 is not set and is not opened for 30 seconds. As already mentioned, the variable winning device 130 is a winning area configured to improve the winning rate when opened, so as a result of the slot game, even if it is 0.6 seconds, 30
The opening of the variable prize winning device 130 even in seconds brings benefits to the players, but especially when the variable display device 110 is opened in a specific display mode [7.7.7] as a result of a slot game. This includes the possibility that the variable winning device 130 will be opened for a maximum total of 300 seconds, taking into account the repetition of the opening mode of the variable winning device 130 for 30 seconds due to winning in the special ball winning area. ,
This will bring extremely large profits to the players. Therefore, how often the specific display mode occurs is a matter of great concern to both players and gaming parlors. However, even if the pachinko game machine is adjusted in a well-balanced manner, the variable display device 110
As mentioned above, the frequency with which a particular display mode is displayed depends on weather conditions and other fluid conditions, and it is extremely difficult to provide fair services to all players. Therefore, the pachinko game machine 100 of the present invention is provided with a specific aspect occurrence rate control means 800 so as to be able to provide fair services to many players. This specific aspect occurrence rate control means 800 includes a specific aspect giving means, a specific aspect avoiding means, and a condition setting section 80.
It is equipped with 2. First, the condition setting section 802
This is to set the frequency of displaying in a specific display mode [7.7.7], and this condition is set using AND gates G15, G16, G17, G21, G2.
2, by selecting G23. For example, even if a slot game is played 300 times, variable display device 1
10 does not have a specific display mode [7.7.7], the variable display device 110 is forcibly activated [7.7.7]
If the variable display device 110 changes to the specific display mode [7.7.7] five times during the business hours of the day, then the variable display device 110 changes to the specific display mode [7.7.7]. If the specific display mode is to be forcibly avoided, the condition setting unit 802 selects the AND gate G15 and the AND gate G21. Further, a specific ball detection signal is applied as a count-up clock to the clock input terminal CK of the counter 811, which constitutes the central structure of the specific mode imparting means, and an AND gate G is applied to the reset terminal R.
9 outputs are added. Therefore, the counter 811 indicates that the slot game is 1.
The counter increments each time the operation is performed, and if the condition setting unit 802 selects the AND gate G15, the variable display device 110 never displays [7.7.7]
If the slot game is played 300 times without a specific display mode, at the time the 300th slot game is played, the count-up output is output to AND gate G15, OR gate G18, and AND gate G19 (in the initial state, AND gate G19 is It is opened by the output of the counter 821.The counter 821 will be described later.), OR gate G
Preset counters 505a, 5 via 20
05b, 505c preset enable terminal
Add to PE. Preset counters 505a, 505b, 50
A preset value is applied to the preset input terminal 5c from the preset value setting section 803, and when a signal is applied to the preset enable terminal PE, the preset value setting section The preset value set by 803 is set. Therefore, if the setting value by this preset value setting section 803 is set to [7] in advance, if the specific display mode [7.7.7] does not occur even once during the slot game that is repeated 300 times, the slot game will be played for the 300th time. When the slot game is played, the count values of the preset counters 505a, 505b, and 505c take on a specific display format of [7.7.7], regardless of the operation of the counter drive circuit 503. In this way, when the display mode of the variable display device 110 is forcibly changed to the specific display mode [7.7.7], the discrimination circuit 601 closes the AND gate G8 and opens the AND gate G9. Then, the differential pulse generated by the differential circuit 602 at the timing when the counter drive circuit 503 lowers the gate signal g5 is applied to the timer 604 via the AND gate G9 and the OR gate G29, and the variable winning device 130 is activated for 30 seconds. develop. Then, the output of the AND gate G9 is applied to the reset input terminal R of the counter 811, so the count value of the counter 811 is cleared, and the counter 811 must display 300 consecutive times until the display mode [7.7.7] occurs. , the variable display device 110 is again forced into the display mode [7.7.7]. As described above, according to the present invention, the variable display device 11
Because of the probability deviation of 0, no matter how many times you play the slot game, the specific display mode [7.7.7] does not occur, but if you play the slot game a preset number of times, you will definitely get [7.7.7]. ] Since the specific display mode is generated, the variable prize winning device 130 can continuously win a jackpot for many players, so that it is possible to provide an average service. Furthermore, the specific aspect occurrence rate control means 80 of this embodiment
0 is equipped with a condition setting section 802, so if the condition setting section 802 selects AND gate G16, if the slot game is played 200 times without a specific mode occurring, if AND gate G17 is selected. , when the slot game is played 100 times without the specific mode occurring, the variable display device 110 can be forcibly changed to a specific display mode [7.7.7]. Therefore, by providing the condition setting section 802 in this manner, it is possible to extremely easily set the so-called collection desk and service desk, and adjust opening services on the new opening day. Next, the output of AND gate G9 is applied to the clock input terminal CK of counter 821, which constitutes the central component of the specific mode avoidance means. Therefore, the counter 821 is the variable display device 110
counts up each time it becomes a specific display mode [7.7.7], and if the condition setting unit 802 selects AND gate G21, the variable display device 110 displays 5 times [7.7.7]. When the specific display mode is reached, the count-up output is applied to the AND gate G25 and the AND gate G19 via the AND gate G21 and the OR gate G24, and the AND gate G25 is opened and the AND gate G1 is output.
Close 9. Therefore, even if the variable display device 110 momentarily changes the result of a subsequent slot game to the specific display mode [7.7.7], the variable display device 110 will immediately display [7.7.8] as described below. The variable winning device 130 also remains closed. That is, the slot game result variable display device 11
Even if 0 is displayed as [7.7.7],
The differential pulse generated by the differential circuit 602 at the end of the slot game is applied to the AND gate G25 via the AND gate G9. When the variable display device 110 has already entered the specific display mode of 5 times or more [7.7.7], the counter 821 has already counted 5, so the ad gate G25 is open, and therefore the above The differential pulse is applied to the reset terminal R of timer 604 via AND gate G25, and is also applied to the clock input terminal of preset counter 505c via AND gate G25 and OR gate G7. Therefore, even if the display mode of the variable display device 110 becomes a specific display mode [7.7.7] for a moment, the count value of the preset counter 505c is incremented by one count due to the differential pulse generated by the differentiating circuit 602. Therefore, the display mode of the variable display device 110 becomes [7.7.8]. Moreover, since the timer 604 is also reset at the same time, the variable prize winning device 130 does not open for 30 seconds, and the timer 604 due to the output of the discrimination circuit 601
Open only for 0.6 seconds, which is the set time in step 3. Thereafter, in the same manner, the provisional variable display device 110
Even if the display mode becomes [7.7.7] for a moment, the display mode of the variable display device 110 instantly changes to [7.7.8], and the variable winning device 130 is opened for only 0.6 seconds. Also, at this time, the AND gate G19 is connected to the counter 82.
1, so even if the counter 811 counts the preset number of slot games to 300, the counter up output is blocked by the AND gate G19 and the variable display device 110 It does not affect the display mode. If a reset signal is applied to the reset terminal of the counter 821 by manual operation from the operation panel after the business hours of the day have ended, the specific mode avoidance means will operate in the same manner the next day. In addition, the number of times the variable display device 110 changes to a specific display mode [7.7.7] during the business hours of one day is set to 4.
If it is allowed up to three times, the condition setting unit 802 selects the AND gate G22, and if it is allowed up to three times, the condition setting unit 802 selects the AND gate G23. Therefore, according to the present invention, the specific ball winning areas 120a, 120b,
Even if the winning rate for 120c increases or the frequency at which the variable display device 110 becomes in the specific display mode [7.7.7] increases due to the probability deviation of the variable display device 110 itself, the condition setting unit The variable display device 110 will not be in the specific display mode [7.7.7] more than the number of times set by 802, and the variable winning device 130 will not be in the open mode for 30 seconds. In the above description, the counter 811 was explained as counting the number of slot games, but if a pulse oscillator is connected to the clock terminal CK of the counter 811, and a specific display mode does not occur even once within a predetermined period of time, it is possible to , variable display device 110
may be forced to be displayed in a specific manner. Furthermore, in the above, as an example of an electric accessory, an example is shown in which a slot game or a roulette game is played by winning a prize in a specific winning area, and the opening mode of the variable winning device changes in response to the game result. However, the electric accessory may be of any other form as long as it corresponds to the gaming state and the player's profit changes significantly. Further, in the above, an example has been shown in which the specific aspect occurrence rate control means 800 includes both the specific aspect adding means and the specific aspect avoiding means, but the specific aspect occurrence rate controlling means 800 includes the specific aspect adding means and the specific aspect avoiding means. A certain purpose can be achieved even if each is provided alone. Further, in the above explanation, the counter 821 is reset by manual operation when the game store closes, but in pachinko parlors where game parlors are centrally managed, the central control device automatically resets the counter 821 when the game store closes. You may also do this.

【effect】

As explained above, according to the present invention, it is possible to almost perfectly adjust the frequency with which the electric accessory enters a specific gaming state that is advantageous to players, and therefore it is possible to It becomes possible to provide services fairly. Furthermore, by operating the condition setting section 802, it is possible to freely set the frequency with which the electric accessory enters a specific gaming state, so it is possible to set or change the so-called service table or collection table, or to open a new store. Adjustments essential to the management of a game parlor, such as time release services, can be made extremely easily.
