Description

The present invention relates to a variable display device capable of variably displaying a plurality of pieces of identification information, and causing the variable display device to perform a variable display operation based on establishment of a start condition. And a game control circuit for generating a special game on condition that the stop result mode at the time of terminating the variable display operation based on the satisfaction of the stop condition forms a predetermined special mode. .

(Related Art) A representative game machine that performs a variable display operation of identification information on a variable display device and generates a special game on the condition that a stop result mode when the variable display operation is completed forms a predetermined mode. In a typical first-type pachinko machine, when a special game is generated, a large amount of prize balls are generated in a short time, and the prize balls are ejected from the prize balls. Players are very popular because they can get a lot of gaming profits.

In such a gaming machine, if the occurrence rate of the special game is not set properly, the profit balance between the player and the game point is lost, so that the specific winning opening as a starting condition for performing the variable display operation is performed. The winning rate of a specific game was adjusted by adjusting the winning of the game with a game nail implanted in the game board.

However, the adjustment of the game nail requires a highly skilled technique, and the fact that the number of times the variable display is performed by the variable display device can be relatively easily recognized by the player, and the variable display can be performed by the player. There are times when it is not possible to select a pachinko machine that is performed less frequently, and since a number of pachinko machines are installed in the game store, it takes a long time to adjust all the pachinko machines, Therefore, in recent years, gaming machines capable of variably setting the occurrence rate of special games have been developed.

(Problem to be Solved by the Invention) When the occurrence rate of a special game is variably settable, the setting change operation is performed after the game store is closed.
If the setting of the rate of occurrence of a special game is changed during the operation of a game store and the rate of occurrence of the special game is changed during the course of business, the player will be distrusted.

On the other hand, if it is easy to change the setting of the rate of occurrence of special games, illegal acts such as raising the rate of occurrence only for specific players by collaborating with the clerk of the player and the amusement store are performed. During a work for solving a trouble that occurs during a game or the like, the setting may be changed by touching the setting change operation unit by mistake.

For this reason, it is desirable that the setting change cannot be easily performed during the game, but conversely, if the setting change of the occurrence rate of the special game requires complicated work, the inspection of the gaming machine or the like is required. When changing the settings of a large number of gaming machines after business hours of the gaming shop, the operation for a long time is required.

An object of the present invention is to solve such a problem by enabling a setting change operation of the occurrence rate of a special game in association with a power supply operation of a gaming machine.

(Means for Solving the Problems) The present invention has been proposed in view of the above, and includes a variable display device (4) capable of variably displaying a plurality of pieces of identification information and a variable display device based on establishment of a start condition.

On the other hand, the control device 70 is provided with a probability setting device 80 for setting the probability of occurrence of a special game.

The probability setter 80 is a case of the control device 70 as shown in FIG.
It is arranged on the back of 81, and the pin from the small hole 82 provided in the case 81
A setting switch 85 (setting SW6), which is turned on when the 83 is inserted and the setting button 84 is pressed, and a 7-segment LED, which is disposed on the surface of the case 81 and whose display is controlled based on the ON signal of the setting switch 85 And a setting display section 86.

When the power of the control device 70 is turned on while pressing the setting button 84, the setting display section 86 flashes, and when the setting button 84 is pressed as it is, the setting display section 86 carries up the numerical value one by one, and then turns off the power. Then, when the power is turned on again, data corresponding to the numerical value (set value) displayed on the setting display unit 86 is stored as a random number value in the RAM 75 of the control device 70. After this storage, the setting display section 86 is turned off.

This winning random number value corresponds to the value of the jackpot in the random number generated by the control device 70. In this case, for example, when the numerical value displayed on the setting display unit 86 is 1, the probability of occurrence of the special game of the jackpot is 1 /
240, 1/2 for 1/2, and 1/22 for 3
5, also 4 is 1/215, 5 is 1/210,
Similarly, when it is 6, it is determined to be 1/200.

Also, when the setting button 84 is pressed in a normal state (the power is on), the set numerical value is displayed on the setting display unit 86, and when the setting button 84 is pressed again, the setting display unit 86 is turned off.

The setting button 84, setting switch 85,
The setting display unit 86 and the like may not be provided in the control device 70, but may be provided in another position of the back mechanism using a dedicated case, or may be attached to another device.

A backup battery 87 is provided so that the stored value of the RAM 75 does not disappear due to power interruption or the like. When the power supply voltage falls below a predetermined value, the backup battery 87 is switched to the power supply backup battery 87 of the RAM 75. ing. 88 covers the backup battery 87 during manufacturing
The insulating sheet sandwiched between the pins 89 prevents the battery 87 from being consumed by being pulled out when installed in a pachinko parlor. However, RAM with capacitor and battery with RAM75
Alternatively, an EEPROM may be provided.

Further, in addition to the above-described jackpot random value, the control device 70 stores in advance random hit value data, random hit value data, and random hit value data. Medium hit random value data has a normal probability (for example, 1 /
420), a random value that generates a medium hit with a high probability (for example, 1/64), and a random number value that generates a hit with a normal probability (for example, 1/7). And a high probability (for example, 1 /
In 1), the random number value that generates a hit and the random number value data of the concentrated hit are set to a random number value that generates a concentrated hit described later with a predetermined probability (for example, 1/200), and these are selected by the control device 70. You.

Next, the contents of control will be described based on the flowcharts of FIGS.

FIG. 11 shows a main routine, and FIGS. 12 to 14 show an interrupt routine. When the power of the control device 70 is turned on, the main routine and the interrupt routine start, and the I / O
The port and RAM are initialized (0.01,0.
In this case, when the power is turned on while pressing the setting button 84 of the probability setting device 80 and the setting SW6 is turned on, the setting switch flag and the setting flag are turned on, the setting display section 86 flashes, and the special jackpot game is performed. Can be set and changed. Then, when the setting button 84 is pressed in this state, the numerical value displayed on the setting display unit 86 is incremented by one. After a predetermined numerical value is selected, the power is turned off and the power is turned on. The jackpot random numbers (1 to 6) corresponding to the numerical values are stored in the RAM, and the setting display unit 86 is turned off (0.02 to 0.09 in FIG. 11 and 2.07 to 2.13 in FIG. 13).

Thus, by operating the setting button 84 of the probability setting device 80 and operating the power supply of the control device 70, the jackpot random number value, that is, the probability of occurrence of the special jackpot game can be freely and easily set while looking at the display of the setting display section 86. Yes, you can change it. The probability of occurrence of this special jackpot special game is, for example, 1/240 when the numerical value (set value) displayed on the setting display unit 86 is 1, 1/230 when it is 2, and 1/230.
When it is $ 6, it is 1/200.

Then, when the game is started, the hit ball is a specific winning opening 6a, 6
b, 6c, the start SW1,2,3
Is turned on, and when it is turned on, the number of times these are turned on is stored up to four times, and the game process is started. At this time, the stored number display LE of the variable display device 4 corresponds to the number of stored ON (unprocessed numbers) of the start SWs 1, 2, and 3.
D22 is lit (0.14-0.15 in FIG. 11, 2.03 in FIG. 13).
~ 2.05).

In the interrupt processing, when the start SWs 1, 2, and 3 are turned on, the values of the generated random numbers are read, and the display symbols when the LEDs A, B, and C of the variable display device 4 are stopped are selected. In addition, timer updating and output processing in the main routine are also performed (2.06, 2.18, 2.14 to 2.17).

When the game process is started, the number of stored ONs of the start switches 1, 2, and 3 is decremented by one as shown in FIGS. 15A and 15B, and the rotation of the LEDs A, B, and C of the variable display device 4 (conversion display). ) Is started, the character "Rotating" is displayed on the operation state display LED 52, the game lamps 13a and 13b are turned on, and a sound indicating that the disk is rotating is output (4.01 to 4.05).

Then, based on the value of the random number read in the interrupt processing, it is first determined whether or not a big hit has occurred. At this time, if the value of the read random number matches the jackpot random number value in the set RAM, it becomes a jackpot and the special jackpot game (jackpot game) is entered (4.06 to 4.18).

The jackpot is relatively unlikely to occur when the setting value is small, and relatively easily occurs when the setting value is large.

In this case, if there is no jackpot, the value of the read random number is compared with another random value. Then, if the value of the random number is not equal to the random number value of the hit concentration, a medium hit random value 1 and a hit random value 1 that generate a hit and a hit with a normal probability are selected. On the other hand, when the value of the random number coincides with the random number value of the hit concentration, a hit concentration flag is set, and a random number value 2 and a random value 2 per hit which generate a medium hit and a hit with a high probability are selected. (4.19 to 4.21).

That is, when there is no hit concentration, the probability of occurrence per hit and hit is normal probability (for example, 1/420, 1/7), and when hit concentration occurs, the probability of occurrence per hit and hit is large. (For example, 1/64, 1/1).

In the case of non-concentration, if the value of the read random number matches the medium random number value 1, the medium random number 1
If it matches, it will be a hit and a special game (medium hit game) and a special game (hit game) will be entered respectively (4.22, 4.23, 4.28, 4.29).

When the hit concentration occurs, the hit concentration lamp 54 flashes, a sound of the hit concentration is output, and if the value of the read random number matches the random number value 2 of the middle hit, the random number value 2 of the middle hit and the out come match. If it does, it will be a hit, a middle hit game and a hit game (4.
24-4.29).

Here, when there is neither a big hit nor a middle hit or an outright hit, a lost symbol is selected as a stop symbol of the LEDA, B, C of the variable display device 4, and after the elapse of the automatic stop time, the LEDA, B, C is stopped with a losing symbol, a message or the like is normally displayed on the operation state display LED 52, the game lamps 13a and 13b are turned off, and a losing sound is output (4.30 to 4.36).

On the other hand, if you enter a jackpot game due to the occurrence of a jackpot,
As shown in FIGS. 16 (A) and (B), LEDA,
A jackpot symbol (for example, 7, 7, 7) is selected as a stop symbol for B and C, and after the elapse of the automatic stop time, a jackpot symbol is displayed on the LEDs A, B, and C, and a "big jackpot" is displayed on the operation state display LED 52.
Is displayed, the game lamps 13a and 13b are turned off,
The hit display lamps 44 and 53 are flickered, and a big hit fanfare sound or the like is output. At this time, a continuation number counter for counting the number of continuations of the jackpot game,
A winning ball counter for counting the number of winning balls of the variable winning device 5, an opening timer (for example, 20 seconds) for determining the opening time of the variable winning device 5 and the like are set (5.01 to 5.10).

When the wait time for outputting the fanfare sound or the like has elapsed, the solenoid 37 of the variable winning device 5 is turned on (5.11, 5.12).

As a result, the movable members 30a and 30b of the variable winning device 5 are changed from the closed state to the open state in which it is easy to receive a hit ball.
A large number of moving balls 30a and 30b are received by the movable members 30a and 30b, and the variable winning device 5 wins.

When the hit ball that has won the variable winning device 5 passes through the count SW5, the number of winning balls is counted, the number of winning balls is displayed on the count display unit 77, and when the number of winning balls reaches 10, or the open timer is activated. When the time is up, the solenoid 37 of the variable winning device 5 is turned off, the movable members 30a and 30b are returned to the closed state, and one cycle is completed (5.13 to 5.15,
5.19,5.20).

At this time, when the hit ball wins the special winning opening 27 and the cycle SW4 is turned on, the continuation flag is raised and the continuation lamp 42 is blinked, and the continuation number counter is incremented by 1 at the end of the cycle, and thereafter, a new cycle is started. The continuation count is displayed on the continuation count display section 76 (5.16 to 5.18, 5.21 to 5.25).

When a new cycle starts, the solenoid 37 of the variable prize apparatus 5 is turned on again after the elapse of the wait time, and the movable members 30a and 30b of the variable prize apparatus 5 are changed to an open state in which a hit ball can be easily received.

As a result, as in the previous cycle, a large number of hit balls wins in the variable winning device 5, and when the number of winning balls reaches 10, or when the open timer times out, the solenoid 37 of the variable winning device 5 is turned off, The movable members 30a and 30b are returned to the closed state, and the cycle ends. At this time, if the hit ball wins the special winning opening 27, the continuation number counter is incremented by 1 and the next cycle is started.

These cycles are repeated up to ten times, and the big hit game ends when the tenth cycle ends. If the hit ball does not win the special winning opening 27 during the cycle, the jackpot game ends at the end of the cycle at that time.

When the jackpot game is over, the operating status display LE
Normal display is performed on the D52, the hit indicator lamps 44 and 53 are turned off, the big hit sound is stopped, and if the hit hit condition is at this time, the hit hit flag is cleared and the hit hit lamp 54 is turned off. The concentrated sound is stopped (5.26 to 5.31).

That is, the hit concentration at which the occurrence probability of the middle hit and the miss hit increases becomes independent during the game, but this hit concentration disappears with the big hit game. The jackpot sound has priority over the hit concentrated sound.

Also, if you enter the middle hit game due to the occurrence of the middle hit,
As shown in FIG. 17, a middle hit symbol (for example, 3,3, X) is selected as a stop symbol of the LEDs A, B, and C of the variable display device 4, and after the elapse of the automatic stop time, the middle hit symbol is applied to the LEDs A, B, and C. A symbol is displayed, the character "Middle hit" is displayed on the operation state display LED 52, the game lamps 13a and 13b are turned off, the hit display lamps 44 and 53 blink, and a middle hit sound is output (6.01).
~ 6.07).

Then, an opening timer (for example, 5.9 seconds) for setting the opening time of the variable winning device 5 is set, and after the wait time elapses, the solenoid 37 of the variable winning device 5 is turned on, and the movable members 30a and 30b are in an open state in which it is easy to receive a hit ball. Is converted to (6.08 to 6.10).

As a result, the hit ball that has flowed down wins the variable winning device 5, and when the open timer expires thereafter, the solenoid 37 of the variable winning device 5 is turned off, and the movable members 30a and 30b are returned to the closed state. , The hit display lamps 44 and 53 are turned off, the normal display is performed on the operation status display LED 52, the middle hit sound is stopped, and the middle hit game is ended (6.11).
~ 6.15).

Also, if you enter a game due to the occurrence of a hit,
As shown in FIG. 18, a symbol (for example, 7, X, X) is selected as a stop symbol of the LEDs A, B, and C of the variable display device 4, and after the elapse of the automatic stop time, a symbol is detected for the LEDs A, B, and C. Is displayed, the character "out of contact" is displayed on the operation state display LED 52, the game lamps 13a and 13b are turned off, and the out of contact sound and the like are output (7.01 to 7.06).

And the opening timer of the variable winning device 5 (for example, 0.5 seconds)
Is set and the solenoid of the variable winning device 5 is operated until the open timer times out after the lapse of the wait time.
37 is turned on (7.07 to 7.11).

As a result, when the movable members 30a and 30b of the variable winning device 5 are instantaneously opened and closed in the out-of-game, the operation state display L
The normal display is displayed on the ED52, the hitting sound is stopped, and the hitting game ends (7.12, 7.13).

FIG. 19 shows each control in function-specific blocks.The probability of occurrence of a jackpot game is determined by operating the setting SW and the power supply.
The set value setting unit displays the set value on the setting display unit, and the jackpot random value selection unit selects and sets the jackpot random number values (1 to 6) corresponding to the set value.

When the game starts and the start SW is turned on, the prize storage control means displays the stored value on the stored number display LED, and the operation timing control means displays each of the LEDs A, The display of B and C is converted, and at the same time, the random number generated by the random number generation means is written to the random number storage means, and the written random number is determined by the random number judgment means to the big hit random number value, the hit concentrated random number value, and the middle hit selected by each selection means. The random number value 1 or 2 is compared with the random number value 1 or 2 per miss.

When there is no hit concentration, each selecting means selects a random value 1 having a normal occurrence probability of a medium hit and a hit, and selects a random value 2 having a high occurrence probability of a middle hit and a hit when there is a hit concentration. . Then, the big hit symbol selected by the symbol generating means at the time of the big hit, the middle hit symbol at the time of the middle hit, the same hitting pattern at the time of the hitting, and the loss pattern at the time of the loss. And the operation timing control means stops the LEDs A, B, and C of the variable display device at the corresponding symbols.
If there is hit concentration, the hit control means drives the hit lamp.

Then, in the case of a big hit, the big hit control means, according to the judgment of the hit judging means, the big win port control means, the hit display means, the solenoid of the variable winning device according to the detection of the continuous SW, the count SW, etc., the hit display lamp And drive the continuation display lamp, continuation count display section, count display section,
Perform a jackpot game.

At the time of the middle win, the middle hit control means drives the solenoid of the variable winning device and the hit display lamp via the big winning opening control means and the hit display means according to the judgment of the hit judgment means, and executes the middle hit game.

In the event of a hit, the hit control means drives the solenoid of the variable winning device and the hit display lamp via the special winning opening control means and the hit display means in accordance with the judgment of the hit judging means, and executes the hit hit game.

Here, if the hit determination means is in the hit concentration, the hit concentration disappears with the end of the big hit. Due to the disappearance of the hit concentration, the selection means selects the random value 1 of the normal occurrence probability of the medium hit and the miss, and the hit control means stops the hit display lamp.

The operation state display means is an operation timing control means,
The game lamp is driven based on the signal from the hit determination means, and a predetermined display is provided on the operation state display LED.

The jackpot random number value is held by the backup battery via the backup control means when the power is turned off.

As described above, the present pachinko machine can freely and easily set the probability of occurrence of the jackpot game while watching the display of the setting display unit 86 by operating the setting button 84 of the probability setting device 80 and the power supply of the control device 70. Can be changed.

For this reason, when adjusting the payout rate of the pachinko machine, the nail around the specific winning opening 6a, 6b, 6c is adjusted to adjust the specific winning opening 6a, 6b,
There is no need to change the winning rate of 6c, and the payout rate can be easily adjusted by changing the probability of occurrence of the jackpot game.

Therefore, it is not necessary to perform a nail adjustment which requires skill and a great deal of labor and time for the work, and it is possible for the game shop to easily perform the ball adjustment, and the inspection and handling properties are greatly improved, which is preferable. Pachinko machines can be secured.

In addition, since the probability of occurrence of the jackpot game can be changed, if it is easy to win a hit ball in the specific winning opening 6a, 6b, 6c, the variable display device 4 becomes easier to start without increasing the payout rate so much. Interest in games can be sufficiently enhanced. In addition, by periodically changing the probability of occurrence of the jackpot game, it is possible to prevent the table selected by the player from being biased.

By the way, the nails on the entrance side and the upper part of the special winning openings 6a, 6b, 6c are formed by the pins 46 and the fence members 47 made of resin integrated with the substrate 23, so that the special winning openings 6a, 6b, 6c are won. The road is constant and cannot be widened or narrowed.

As a result, it is possible to reliably prevent an illegal act such as bending a life nail or the like of the specific winning opening 6a, 6b, 6c and unjustly changing the winning rate of the specific winning opening 6a, 6b, 6c. On the other hand, for the game store,
By adding unfair tampering to the nails, fueling euphoria,
It is possible to prevent the pachinko machine from spoiling its original game and interest.

Alternatively, a nail may be driven from the front wall 45 of the specific winning opening 6a, 6b, 6c, or a pin 50 with a base may be fitted to the nail (see FIGS. 20 and 21). Can be prevented, and fraudulent acts can be prevented. In addition, a nail made of a shape memory alloy may be used to prevent bending.

In addition, when resin is used for the nail, rebound of the hit ball which has not been obtained in the past can be obtained, and when used in combination with the nail, the movement of the hit ball can be further varied by combining these.

On the other hand, if a big hit occurs during the game, the variable winning device 5 is opened until 10 hit balls are won per cycle or a predetermined time (20 seconds) elapses, and this is repeated up to 10 times as the cycle continues. Therefore, when a big hit occurs, sufficient prize balls can be obtained.

In addition, when the middle hit occurs, the variable prize winning device 5 once,
When a miss occurs for a predetermined time (5.9 seconds), the variable winning device 5 is opened once (0.5 seconds). Then, the hitting ball comes to win with this opening, and the occurrence probability changes depending on whether or not the hit state and the hit state are hit and concentrated. In other words, it occurs independently with a predetermined probability during the hit-intensive game, and when the hit-free state is not established, the medium hit and out-of-hit have the normal probability (1/420, 1/7), and the hit-intensive state is established. In some cases, the medium and outliers have a high probability (1/6
4,1 / 1).

In the middle hit, several hits will win, and in the hit, if you are lucky, one or two hits will win, but if the hit concentration occurs, the hit rate is low, but the middle hit and the hit often occur As a result, not only the big hit but also the expectation of the hit concentration can be increased, and if the hit concentration occurs, the number of acquired balls can be gradually increased.

For this reason, it is possible to play a variety of games in conjunction with the jackpot, and when a jackpot occurs, a large jackpot game in which a large number of acquired balls are obtained in a short time, and when a hit concentration occurs, although gradually, The same pachinko machine can be used to win prize balls by increasing the frequency of hits, and a pachinko machine full of interest can be secured.

In addition, since the jackpot concentration disappears when a jackpot occurs, if the jackpot occurrence probability is reduced, the jackpot is less likely to occur, but if a jackpot occurs, the period of the minute jackpot continues for a long time, whereas the jackpot If you increase the probability of occurrence, the jackpot is likely to occur,
When a hit concentration occurs, the period of the hit concentration becomes short. Therefore, even if the probability of occurrence of the jackpot is increased or decreased to some extent, the payout rate does not change so much, so that the setting of the jackpot probability and the payout rate is easy, and Setting according to the business policy becomes possible without difficulty. This also makes it possible to widen the setting range of the jackpot probability.

As a jackpot probability setting device 80, a password input key 90 for inputting a predetermined password as shown in FIG.
And a key switch 92 operable by a setting key 91 also serving as the front frame 14 of the pachinko machine, a setting display unit 93 for displaying a set numerical value, and a setting button 94 for instructing completion of setting.
When the password is input by the password input key 90, the probability can be set. Then, when the setting key 91 is inserted and the key switch 92 is operated, the setting display unit 93 displays the numerical value one by one. When the setting button 94 is pressed after selecting a predetermined numerical value, the hit random number value corresponding to the numerical value may be stored in the RAM of the control device 70. In this case, there is no need to operate the power supply.

(Effect of the Invention) As described above, according to the present invention, the game control by the game control means is started at the time of normal power supply by the control switching means for switching the control content executed by the game control circuit, and the special game generation When the power is turned on in a state where the predetermined operation is performed by the change operation means for performing the change operation of the rate, the special game occurrence rate change control means changes the occurrence rate of the special game to a plurality of stages. Control can be started.

Therefore, during the game, unless the power of the gaming machine is operated, the change control by the special game occurrence rate change control means is not performed, so that the occurrence rate of the special game is variably set due to an illegal operation or an erroneous operation. Disappears.

In addition, when the special game occurrence rate is variably set, the change control by the special game occurrence rate change control means is started using the change operation means used for performing the change operation of the special game occurrence rate. It is possible to use one unit without using a new unit to start the change control, and the operation can be simplified.
It becomes easy to variably set the rate of occurrence of special games of a large number of gaming machines after the business operation of the gaming store.
