Description

  The present invention relates to a pachinko machine.

  FIG. 38 is an explanatory front view of a conventional pachinko machine. A conventional pachinko machine 700 includes a game board 702 in which a game ball flow area is formed, a launch handle 701 that adjusts the launch intensity of a launcher that launches the game ball to the flow area, and a starter disposed on the game board 702. A mouth 703, an image display device 704, a special electric accessory 706, an upper tray 705 for storing a prize ball and a rental ball, and a speaker 709 are provided.

  When a game ball launched by the player turning the launch handle 701 wins the start opening 703, the MPU built in the pachinko machine 700 obtains a random number from the random number generation means, and stores the obtained random number in a predetermined memory. Store. Also, when the game ball wins the start opening 703, the image display device 704 starts displaying a moving image, and the MPU determines that the game is a big hit if the random number stored in the memory matches a predetermined big hit value. If they do not match, it is determined to be lost. Hereinafter, the determination of the big hit or the loss is referred to as a big hit determination.

  The moving image displayed by the image display device 704 includes a symbol moving image that displays the symbols in a variable manner and a background moving image that is displayed on the background. As the background moving image, a moving image based on a known animation, a TV drama, a movie, or the like is used in addition to a moving image original by a pachinko machine maker. The symbol moving image is a symbol array (hereinafter referred to as symbol sequence) representing a plurality of types of identification information (for example, numbers 0 to 9) in three horizontal display areas on the screen from the top to the bottom. It is a display mode to be moved to. In addition, depending on the model, the symbol moving image is displayed such that the symbol sequence is moved from the right to the left of the screen at three positions in the vertical direction on the screen, or the symbols constituting the symbol sequence are displayed in the same display area. It is a display mode that displays. A display mode in which each symbol constituting the symbol row changes in the display area as described above is called symbol variation. The speaker 709 reproduces music corresponding to the moving image while the image display device 704 displays the moving image.

  When a predetermined time elapses after the image display device 704 starts displaying a moving image, the variation of the symbol stops in each display region, and the symbol corresponding to the result of the big hit determination by the MPU described above is fixedly displayed in each display region. The Here, the fixed display means a display state in which the symbol does not change again after the change stops. For example, if the result of the big hit determination is a big hit, a symbol having the same number such as “777” is confirmed and displayed. If the result of the big hit determination is lost, the same value such as “767” is displayed. The symbols that do not have the numbers are fixed and displayed.

  Hereinafter, a combination of symbols indicating that the result of the big hit determination is a big hit is referred to as a big hit symbol, and a combination of symbols indicating that the result of the big hit determination is a loss is referred to as a lost symbol. In addition, the period from when the image display device 704 starts displaying a moving image to when the big hit symbol or the lost symbol is fixedly displayed is counted as one variation of the symbol.

  When the image display device 704 confirms and displays the big win symbol, a big win occurs, and the variable winning device 706 opens the opening / closing member 707 and opens the big winning port 708. Since the big winning opening 708 has a larger winning area than the normal winning opening, winning becomes easy. Then, there is a condition that a specified number (for example, about 9) of game balls have won a prize winning opening 708 or a condition that the opening time of the prize winning opening 708 has reached a specified time (for example, about 30 seconds). When satisfied, the opening / closing member 707 is closed and the special winning opening 708 is closed.

  A round from the opening of the special winning opening 708 to the closing is defined as one round, and a plurality of rounds (for example, a maximum of 14 rounds) are executed, during which the player can acquire a large amount of prize balls. Hereinafter, the game from the start of the first round to the end of the final round is referred to as a jackpot game. During the jackpot game, the image display device 704 displays a moving image unique to the jackpot game, and the speaker 709 reproduces music corresponding to the moving image.

In this embodiment, the special symbol display device 31, the normal symbol display device 33, the special symbol hold number display device 32, and the normal symbol hold number display device 34 are each constituted by an LED, but are constituted by a liquid crystal display device or the like. You can also.

  The special symbol display device 31 is composed of a plurality of LEDs (for example, seven as shown in FIG. 10B), and the game balls are connected to the first start port 21 or the second start port 22, respectively. When winning, it blinks in a predetermined blink pattern. The light emission color when these LEDs are turned on and the background color of the LEDs when they are turned off constitute a special symbol, and the state where the LEDs are blinking is a state where the special symbol is variably displayed.

  The special symbol display device 31 causes each LED to blink at random, and a big hit occurs when the combination of the LED that is turned on and the LED that is turned off when the blinking stops is a specific combination. Depending on the type, the type of jackpot will vary. The jackpot type is configured by combining two or more of the maximum number of rounds that can be executed in the jackpot game, the normal jackpot, the probability variation jackpot, and the number of balls. Further, depending on the type of jackpot, either the first variable winning device 24 or the second variable winning device 25 is operated to perform a big win game.

  When the special symbol display device 31 variably displays the special symbol, if the game ball wins the first start port 21 or the second start port 22, the special symbol variation display based on the winning is not immediately executed. , Once suspended. The special symbol hold number is displayed by the special symbol hold number display device 32. In this embodiment, the special symbol reservation number display device 32 is constituted by four LEDs, and displays the special symbol reservation number by the number of lighting of the LEDs. That is, in this embodiment, the maximum number of special symbol reservations is four.

  The normal symbol display device 33 is composed of a plurality of LEDs (for example, two as shown in FIG. 10B), and the emission color when each LED is turned on and the background color of the LED when the LED is turned off. Constitutes a normal symbol. In addition, the state in which the normal symbol display device 33 blinks the LED is a state in which the normal symbol is variably displayed.

When the normal symbol display device 33 variably displays the normal symbol, when the game ball passes through the gate 23, the normal symbol variation display due to the passage is suspended, and the number of normal symbol reserves is the normal symbol reserve. It is displayed by the number display device 34. In this embodiment, the normal symbol hold number display device 34 is constituted by four LEDs, and displays the normal symbol hold number by the number of lighting of the LEDs. That is, in this embodiment, the number of normal symbol reservations is a maximum of four.

(Hidden probability change)
In addition, the pachinko machine 1 is configured to perform a so-called latent probability change that does not indicate to the player that the game state has changed to the probability change game state when the game state has changed to the probability change game state. .
Therefore, even when the game state changes to the probability change game state, the effect display 30 does not display an image specific to the probability change and does not change in time. Here, “short time” means that the time required from the timing when the special symbol and the production symbol are started to be changed to the timing when the variable display is ended is shortened, and the normal symbol is started after the variable display is started. This is a gaming state in which the time required to complete the operation is shortened and the opening time of the opening / closing wing piece 27c of the ordinary electric accessory 27 is extended.
Further, since the pachinko machine 1 does not have a function of increasing the probability of determining a hit in the normal symbol hit determination in order to perform the latent probability change, even when the gaming state is changed to the probability changing gaming state, The time during which the ordinary electric accessory 27 opens the opening / closing blade piece 27c is not extended. In other words, support using ordinary electric accessories, so-called electric support, is not performed.

(Direction display 30)
Here, the effect indicator 30 will be described with reference to the drawings.
FIG. 11A is an explanatory diagram showing a state in which the effect symbol is variably displayed on the effect indicator 30, FIG. 11B is an explanatory diagram showing a state where the effect symbol is reached, and FIG. It is explanatory drawing which shows the state by which the big hit symbol was fixedly displayed.

  The effect display 30 is provided for the purpose of enhancing the effect of the special symbol display device 31. That is, as described above, the special symbol display device 31 is composed of a plurality of LEDs, and the effect of the effect is not sufficient only by the blinking of the LEDs. Is increasing.

  The effect symbol is a symbol expressing a plurality of pieces of identification information, for example, a symbol expressing numbers such as 0 to 9 (such as arithmetic numbers or Chinese numerals). The effect indicator 30 starts the change display of the effect symbol at the same time as the special symbol display device 31 starts the change display of the special symbol, and the effect symbol display device 31 displays the change display of the effect symbol at the same time as the special symbol display device 31 ends the change display of the special symbol. Exit. In addition, the effect indicator 30 confirms and displays the effect symbol corresponding to the big hit symbol or the lost symbol that the special symbol display device 31 has determined and displayed.

  Further, the effect display unit 30 displays when the effect design moving image representing the state where the effect design is variably displayed, the background moving image to be displayed on the background of the effect design moving image, and the effect design moving image are not displayed. A moving image, a moving image to be displayed when a big hit occurs, a moving image to be displayed during a big hit game, a customer waiting image to be displayed when no player is attached, and the like are displayed.

  In this embodiment, the variation pattern of the effect symbol moving image displayed by the effect indicator 30 and the background moving image displayed by the effect indicator 30 on the background of the effect symbol moving image are each determined by lottery using random numbers. . Hereinafter, the variation pattern of the effect design moving image displayed by the effect display 30 and the background moving image are collectively referred to as a variation / effect pattern. In addition, a combination of effect symbols that will generate a big hit when the effect indicator 30 stops displaying variation of the effect symbols is called a big hit symbol, and a combination of effect symbols other than the big hit symbol is called a lost symbol.

As shown in FIG. 11, the effect display device 30 has three display areas D1, D2, and D3 arranged in the horizontal direction. Each display area D1-D3 displays the effect design in a variable manner. In this embodiment, the effect display device 30 variably displays a plurality of effect symbols representing numbers 0 to 9 so as to move from the top to the bottom of the screen in ascending order of the numbers. In other words, the effect display device 30 scrolls and displays a plurality of effect symbols representing numbers 0 to 9 in the ascending order of numbers.
The example shown in FIG. 11 (a) represents a certain moment of the effect symbol that is variably displayed in each of the display areas D1 to D3, and the effect symbol “7” is confirmed and displayed in the left display area D1. In the center and right display areas D2 and D3, the effect symbols are variably displayed.

The change pattern of the effect symbol in the period from when the effect indicator 30 starts the change display of the effect symbol to the time when the change display is stopped and until the big hit symbol or the losing symbol is confirmed and displayed in each display area is roughly divided into normal variations. And there is a variation pattern called reach variation. The reach is a display state in which symbols constituting the jackpot symbol are each confirmed and displayed in each display region other than one display region in which the effect symbols are variably displayed. In other words, it is a display state in which one effect symbol is unconfirmed before the big hit symbol is aligned. The reach variation pattern is a variation pattern with reach, and the normal variation pattern is a variation pattern without reach.
In the example shown in FIG. 11B, the effect symbol “7” is confirmed and displayed in the left and right display areas D1 and D3, and the effect symbol is variably displayed only in the center display area D2, ie, a so-called reach state. Show.

  When reaching reach, the effect display 30 performs an effect that makes the player throbbing whether or not the jackpot symbols are aligned. For example, in the example shown in FIG. 11 (b), the fluctuation speed in the central display area D2 is slowed down, and when the effect design 7 appears from the upper end of the screen, the fluctuation speed is further slowed down. Also, once it appears to stop at the effect symbol 7, when the effect symbol 7 passes and the effect symbol 8 tries to stop, the direction of change is reversed, and the effect symbol 7 appears to stop again. Or it makes it seem to stop with the production design 7, and only the display area D2 or the display areas D1-D3 starts a variable display again.

  Further, depending on the type of variation / effect pattern, the time required to display the big hit symbol or the lost symbol after the display of the variation / effect pattern is started (hereinafter referred to as variation time) differs. In particular, since the variation / production pattern including the reach variation pattern spends a long time in the reach portion, the variation time is set longer than the variation / production pattern including the normal variation pattern.

  The reach variation pattern includes a reach variation pattern (hereinafter referred to as a specific reach variation pattern) called a super reach or a special reach with a high probability of definite display of a big hit symbol. This specific reach variation pattern has a particularly stunning structure among reach variation patterns, and the frequency of appearance is low. In addition, when a specific reach variation pattern appears, the probability of a big hit symbol being confirmed and displayed is high, so that the player's expectation for occurrence of a big hit is increased when the specific reach variation pattern appears.

  In this embodiment, as the normal variation pattern, a plurality of types of normal variation patterns of a normal variation A, a normal variation B,..., And as a reach variation pattern, a plurality of types of normal reach variation patterns of normal reach A, normal reach B,. A plurality of types of super reach variation patterns of super reach A and super reach B are set to be selectable. Super reach has the lowest appearance rate among reach variation patterns, but is the reach variation pattern with the highest expectation for jackpot occurrence, and the production in the reach state is elaborate. Yes.

The degree of expectation for the occurrence of jackpot here refers to the reach rate of the reach fluctuation pattern that leads to the jackpot to the total appearance rate that is the sum of the appearance rate of the reach fluctuation pattern that leads to the jackpot and the appearance rate of the reach fluctuation pattern that leads to the loss. It shows the rate of appearance rate.
In the example shown in FIG. 11 (c), the effect symbols 7 are fixedly displayed in the display areas D1 to D3, respectively, and “777”, which is an example of the jackpot symbol, is arranged.

  In addition, as the background moving image displayed by the effect display device 30, different background moving images are set according to the variation pattern and variation time of the effect design moving image. A background moving image according to the variation time of the normal variation pattern is associated with the normal variation pattern, and a background moving image according to the variation time of the reach variation pattern is associated with the reach variation pattern. In particular, the super-reach fluctuation pattern is associated with a background moving image having a sophisticated effect for exciting the reach-specific effect.

  Further, the background moving image is displayed on the background of the effect symbol moving image or is displayed when the effect symbol moving image is not displayed depending on the type. In addition, when a background moving image is displayed on the background of the effect design moving image, the background moving image in an area overlapping the effect design moving image may be displayed so as to show through. Also, among the variation patterns that make up the variation / direction pattern, the direction symbol is displayed in a variable manner at one corner of the screen so that it does not interfere with the background video, and when the reach is reached, the direction symbol is displayed Some are enlarged and displayed in a variable manner. In addition, the display timing of the background moving image differs depending on the variation / effect pattern determined by the lottery, and is the timing and reach to be displayed when the game ball wins the first starting port 21 or the second starting port 22. There is a timing to display when the

In addition to pachinko machine manufacturer original moving images, moving images based on known animations, TV dramas, movies, and the like are used as background moving images. In addition, sounds such as music or sound effects corresponding to the content of the background moving image are reproduced by the speakers 10 to 12.
The music when the super reach is displayed is set so that the acoustic effect of the music is larger than when the normal fluctuation and the normal reach are displayed. For example, in the case of super reach, the surround effect is increased and the low sound level is increased.
That is, when the degree of expectation for the occurrence of the big hit is large, the sound effect is set to be large and the production is excited.

Further, the effect display device 30 displays a specific background moving image, causes a specific character image to appear in the background moving image, or develops a story of the background moving image into a specific story. May foresee that a reach may appear in the near future. Hereinafter, it is called reach notice that suggests the possibility of reach. In this reach notice, there are a reach notice with a low expectation and a reach notice with a high expectation that the jackpot symbol will be confirmed and displayed after the reach.
The expectation here refers to the ratio of the appearance rate of reach notifications that lead to jackpots to the overall appearance rate that is the sum of the appearance rate of reach notifications that lead to jackpots and the appearance rate of reach notifications that lead to losers. Is.

  Further, the effect display device 30 displays a specific background moving image, causes a specific character image to appear in the background moving image, or develops a story of the background moving image into a specific story. May foresee that a big hit may occur in the near future. In the following, suggesting the possibility of a jackpot is called a jackpot notice. In the big hit announcement, there is a continuous announcement that is continuously performed over a plurality of fluctuations of the production symbol in addition to a single announcement that is performed once in a single fluctuation of the production symbol.

As a type of continuous notice, there is a so-called step-up notice or the like in which the degree of expectation for occurrence of a big hit increases gradually every time the big hit notice continues. For example, in the case where the upper limit of the number of special symbol reservations is 4, and when the number of special symbol reservations has reached four, if it is determined that the big hit announcement will be made four times in succession, the background moving image will be set to four times. The background moving image having the highest expectation is displayed in the last fourth time.
The expectation for jackpot occurrence here refers to the appearance rate of the jackpot notice that leads to the jackpot relative to the total appearance rate that combines the appearance rate of the jackpot notice that leads to the jackpot and the appearance ratio of the jackpot notice that leads to the loss. It shows the ratio.

[Main random numbers used in games]
Next, main random numbers used in the game will be described with reference to the drawings. FIG. 15 is an explanatory diagram of random numbers used in the game.

  The hit determination random number R1 is a random number used when the main control MPU 51 performs a hit determination of a normal symbol. In this embodiment, there are 197 values of 0 to 196. The hit determination initial value random number R2 is a random number for randomly determining the initial value of the hit determination random number R1. In this embodiment, there are 197 values of 0 to 196 which are the same as the hit determination random number R1. When the hit determination random number R1 makes one round, the value of the hit determination initial value random number R2 counted at that time is determined as the initial value of the hit determination random number R1. In other words, the initial value of the hit determination random number R1 is randomly determined and the periodicity of the initial value of the hit determination random number R1 is eliminated. It is configured so that symbol hits do not occur.

  The big hit determination random number R3 is a random number used when the main control MPU 51 makes a big hit determination of a special symbol, and in this embodiment, there are 1597 types of 0 to 1596. The big hit determination initial value random number R4 is a random number for randomly determining the initial value of the big hit determination random number R3, and in this embodiment, there are 1597 kinds of 0 to 1596 which are the same as the big hit determination random number R3. When the big hit determination random number R3 makes one round, the value of the big hit determination initial value random number R4 counted at that time is determined as the initial value of the big hit determination random number R3. That is, the initial value of the big hit determination random number R3 is randomly determined to eliminate the periodicity of the initial value of the big hit determination random number R3. It is configured not to generate a jackpot of symbols.

  The jackpot symbol random number R5 is a random number used when the video / audio control MPU 71 determines a jackpot symbol. In this embodiment, there are 100 random numbers from 0 to 99. The jackpot symbol initial value random number R6 is a random number for randomly determining the initial value of the jackpot symbol random number R5, and in this embodiment, there are 100 patterns of 0 to 99 which are the same as the jackpot symbol random number R5. When the jackpot symbol random number R5 makes one round, the value of the jackpot symbol initial value random number R6 counted at that time is determined as the initial value of the jackpot symbol random number R5. In other words, the initial value of the jackpot symbol random number R5 is randomly determined to eliminate the periodicity of the initial value of the jackpot symbol random number R5, thereby specifying by the fraud using the periodicity of the initial value of the jackpot symbol random number R5. The jackpot symbol is not selected.

The reach selection random number R7 is a random number used by the image / audio control MPU 71 to determine whether or not to select a variation / effect pattern including reach variation when the result of the big hit determination is a loss. In this embodiment, the reach selection random number R7 is 239 from 0 to 238.
The first variation group selection random number R8 and the second variation group selection random number R9 are random numbers used by the image / audio control MPU 71 to narrow down variation / effect patterns. In this embodiment, the first variation group selection random number R8 is 241 from 0 to 240, and the second variation group selection random number R9 is 199 from 0 to 198. The variation / effect pattern selection random number R10 is a random number used for determining the final variation / effect pattern from the variations / effect patterns narrowed down by the second variation group selection random number R9. In this embodiment, the variation / effect pattern selection random number R10 is 251 from 0 to 250.

Each of the random numbers described above is realized by a random number counter that counts one from the minimum value 0 to a predetermined maximum value, and the count value of the random number counter is treated as a random number. The random number counter increments by 1 every cycle (for example, 2 ms) in which the main control MPU 51 executes the main program, and returns to 0 when the maximum value is exceeded. The random number generated from the big hit determination random number counter when the game ball wins the first start port 21 or the second start port 22 is stored in the main control work RAM 53.
In addition to the above-described soft random number method using a random number counter, each random number can also be generated using a hard random number method using a random number generation circuit such as a random number generation IC.

[Big hit value table]
Next, the configuration of the jackpot value table stored in the main control ROM 52 will be described with reference to FIG.

  The jackpot value table 52a is a table that stores jackpot values that are referred to when the main control MPU 51 makes a jackpot determination. The jackpot value table 52a is set separately for the case where the gaming state is the normal gaming state and the case where the probability changing gaming state is set, and the jackpot value table is set with more jackpot values than the normal gaming state. The jackpot value is selected from 0 to 1596 random numbers for the jackpot determination random number R1.

  The main control MPU 51 obtains the jackpot determination random number R1 stored in the main control work RAM 53 and the jackpot value set in the jackpot value table 52a when it is time to display the variation of the special symbol. In comparison, if there is a matching jackpot value, it is determined to be a jackpot, and if it does not exist, it is determined to be lost.

  In this embodiment, a total of four jackpot values are set in the normal gaming state, and a total of 35 jackpot values are set in the probability variation gaming state. In other words, the probability of being determined to be a big hit in the big hit determination is set to be 8.75 times higher in the probability variation gaming state than in the normal gaming state.

[Variation / Direction Pattern Table]
Next, the configuration of the variation / effect pattern table stored in the image / audio control ROM 72 will be described with reference to FIG. FIG. 17B is an explanatory diagram showing types of variation / effect patterns.

  The fluctuation / effect pattern table 72a stores a plurality of change / effect patterns selected by the image / audio control MPU 71 so as to be readable. In the fluctuation / effect pattern table 72a, the big hit fluctuation / effect patterns 1 to 311 that can be selected when the result of the big hit determination by the main control MPU 51 is the big hit, and the result of the big hit determination by the main control MPU 51 are displayed. Loss variation / effect patterns 1 to 109 that can be selected in the case of a loss are stored.

  When receiving the effect instruction command from the main control MPU 51, the image and sound control MPU 71 is based on the jackpot determination result, the special symbol hold number and each random number transmitted from the main control MPU 51, and each random number selected by itself. The variation / effect pattern is determined, and the determined variation / effect pattern is read from the variation / effect pattern table 72a.

Variations and production patterns, Button production A, Button production B, ..., Reach notice A, Reach notice B, ... Jackpot notice A, Jackpot notice B, ... ·It is included.

[Variation / Direction Pattern Drawing Method]
Next, a variation / effect pattern lottery method will be described with reference to the drawings.
FIG. 18 is an explanatory view showing a lottery method for variation / effect pattern.

  The jackpot determining random number R3 and the jackpot symbol random number R5 are acquired from the random control counters by the main control MPU 51 when the game ball wins the first starting port 21 or the second starting port 22. The reach selection random number R7, the first variation group selection random number R8, the second variation group selection random number R9, and the variation / effect pattern selection random number R10 are displayed when the image / audio control MPU 71 starts the variation display of the special symbol. Get from each random number counter. The jackpot symbol random number R5 is used when the jackpot determination result is a jackpot.

  Big hit symbol random number R5 0-99, reach selection random number R7 0-238, first variation group selection random number R8 0-240, second variation group selection random number R9 0-198 and variation / effect pattern selection random number R10 0 to 250 are divided into a plurality of groups each having a predetermined number of random numbers as a group. In addition, one variation / effect pattern is associated with each group of the variation / effect pattern selection random number R10.

  If each group of the jackpot symbol random number R5 is the highest group and each group of the variation / direction pattern selection random number R10 is the lowest group, the following is determined depending on which group the random numbers acquired in the higher group belong to: The range of groups that can be selected at the lower level is narrowed down. Further, the lower the group, the more the group is subdivided. In other words, it is devised to prevent the player from getting bored by selecting different variation / effect patterns as much as possible according to the small differences in the game state. In this embodiment, 420 types of variation / effect patterns are prepared to be selectable.

  The main control MPU 51 makes a big hit determination when starting the special symbol variation display (A). Here, if it is determined that the jackpot, the jackpot symbol random number R5 is acquired (A). Here, the jackpot symbol is determined based on the acquired jackpot symbol random number, and the group to which the acquired jackpot symbol random number belongs is determined (a). Subsequently, a time determination is made as to whether or not the gaming state has changed in a short time (c). Further, when it is determined that the previous big hit determination is a loss, the skipping is performed by skipping.

Subsequently, a probability state determination is made as to whether or not the gaming state has changed to a probabilistic gaming state (D). Subsequently, the number of holds of the special symbol is determined from 0 to 4 (e). The main control MPU 51 transmits the jackpot determination result, the jackpot symbol random number, the time reduction determination result, the probability state determination result, and the hold number determination result to the image / audio control MPU 71.
The image / audio control MPU 71 obtains the reach selection random number R7 when the special symbol variation display is started (f). The number of groups of the reach selection random number R7 and the number of random values constituting each group are determined as a result of the jackpot determination (a), the group to which the jackpot design random number (a) belongs, the result of the time reduction determination (c), the probability state determination It depends on the combination of the result of (d) and the result of holding number judgment (e).

  For this reason, the image / audio control MPU 71 determines the result of the jackpot determination (A) transmitted from the main control MPU 51, the group to which the jackpot symbol random number (A) belongs, the result of the time reduction determination (C), the result of the probability state determination. The group to which the acquired reach selection random number R7 belongs is determined based on (d) and the result (e) of the pending number determination. Subsequently, the first variation group selection random number R8 is acquired (G), and the group to which the acquired first variation group selection random number R8 belongs is determined. Subsequently, the second variable group selection random number R9 is acquired (K), and the group to which the acquired second variable group selection random number R9 belongs is determined. Subsequently, the variation / effect pattern selection random number R10 is acquired (K), and the group to which the acquired variation / effect pattern selection random number belongs is determined. Then, the variation / effect pattern associated with the determined group is determined (e).

[Contents stored when special symbol hold occurs]
Next, the contents stored in the hold table of the image / sound control work RAM 73 when the special symbol hold occurs will be described with reference to the drawings.
FIG. 19A is an explanatory view showing the stored contents of the hold table 73a, and FIG. 19B is an explanatory view showing a state in which the storage order of the data stored in the hold table 73a has been raised.

  Note that the hold table is provided for each of the first start port 21 and the second start port 22, but here, the hold table for the first start port 21 will be described as a representative. In this embodiment, it is assumed that the upper limit of the number of special symbol reservations for the first start port 21 and the second start port 22 is four.

  If the game ball wins the first starting port 21 while the special symbol is variably displayed, the big hit determination random number R3, the big hit symbol random number R5 obtained from each random number counter, the short time determination result, the probability state determination result, the hold The number determination result, the reach selection random number R7 and the first variation group selection random number R8 are stored in the corresponding holding order in the holding table 73a. For example, when the special symbol is displayed in a variable manner and the game ball wins the first starting port 21 when the special symbol holding number U is 1, each random number and the storage area of the holding rank second in the holding table 73a The determination result is stored. That is, each random number is stored in the holding ranks 1 to 4 in the winning order of the first start port 21. In the illustrated example, each random number stored in the holding order No. 1 is the oldest in terms of time, and each random number stored in the holding order No. 4 is the latest.

Then, at the timing when the special symbol starts to display the variation display, the second variation group selection random number R9 and the variation / effect pattern selection random number R10 obtained from each random number counter are stored in the storage area of the retention order No. 1 in the retention table 73a. The
Since the big hit determination is performed based on the big hit determination random number R5 stored in No. 1 of the holding order at the start of the variable symbol display of the special symbol, it is acquired when the game ball wins the first start port 21. The jackpot symbol random number R5 and the reach selection random number R7 are stored in the holding table 73a. However, when the result of the jackpot determination performed later is a loss, these random numbers are used for determining the variation / effect pattern. I can't.

  In the example shown in FIG. 19A, the big hit determination random number 7, the big hit symbol random number 23, the reach selection random number 109, and the first variation group selection random number 201 are stored in the second holding order in the holding table 73a. At this stage, since the variation display of the special symbol corresponding to the first holding order is not completed, the second changing group selection random number and the variation / effect pattern selecting random number are not stored in the second holding order. When the special symbol variation display corresponding to the first hold order is completed, the hold order of each stored data is incremented by one as shown in FIG. 19B. Then, the second variation group selection random number 65 and the variation / effect pattern selection random number 103 are stored in the first holding order. The variation / effect pattern corresponding to the variation / effect pattern selection random number 103 is the jackpot variation / effect pattern 244.

The big hit effect data 75a is image data for displaying on the effect display 30 an image indicating that a big hit has occurred when the special symbol variation display is stopped and the big hit symbol is confirmed and displayed. The big hit game data 75b is image data for displaying an effect image during the big hit game on the effect display 30. The customer waiting image data 75c is image data for displaying a predetermined effect image on the effect display device 30 in a so-called customer waiting state in which the special symbol is not variably displayed and the game ball is not being fired. . The error notification data 75d is image data for displaying on the effect display 30 an image indicating the occurrence of a ball breakage, ball clogging, prize ball payout abnormality, or the like, or the occurrence of an illegal act using magnetism. .

[Main game flow]
Next, the main flow of the game in the pachinko machine 1 will be described with reference to the drawings.
(Main processing executed by main control MPU)
First, the flow of main processes executed by the main control MPU 51 will be described with reference to the drawings. FIG. 21 is a flowchart showing a flow of main processing executed by the main control MPU 51 when the power of the pachinko machine 1 is turned on. FIG. 22 is a flowchart showing main processing executed by the main control MPU 51 during the game. In the following description, a process step executed by each MPU is abbreviated as S.

  The main control MPU 51 determines whether or not the power of the pachinko machine 1 is turned on (S1 in FIG. 21). If it is determined that the power is turned on (S1: Yes), a security check is executed (S2), and the stack The pointer is initialized (S3). Subsequently, an interrupt mode is set (S4), and access to the main control work RAM 53 is permitted (S5). Subsequently, peripheral devices of the main control MPU 51 are initialized (S6), and it is determined whether or not the RAM deletion switch 94a (FIG. 12) for deleting the backup data of the main control work RAM 53 is turned on (S7). .

  If it is determined that the data is on (S7: Yes), the data stored in all storage areas of the main control work RAM 53 is erased (S8). Whether or not the RAM erase switch 94a is turned on is determined only once after the power is turned on and not thereafter. Subsequently, the main control work RAM 53 is initialized (S9), and a command for setting the effect control board 400 to the power-on state is transmitted to the effect control board 400 (S10).

  If it is determined in S7 that the RAM erase switch 94a is not turned on (S7: No), it is determined whether or not power-off occurrence information indicating that the power has been cut off due to a power failure is stored (S11). ), If it is determined that it is stored (S11: Yes), a checksum is calculated (S12). Subsequently, it is determined whether or not the checksum stored when the power is turned off matches the checksum calculated in S7, that is, whether or not the checksum is normal (S13). If this is the case (S13: Yes), the initial value upon power restoration is set in the main control work RAM 53 (S14).

  Subsequently, a command for returning the effect control board 400 to the gaming state at the time of power restoration is transmitted to the effect control board 400 (S15), and a payout control start command is transmitted to the payout control board 60 (S16). Thereby, the game at the time of power-off is restarted, and when an unpaid prize ball remains, the unpaid prize ball is paid out. Subsequently, an interrupt is set and the interrupt is permitted (S17), and the process proceeds to game control.

  When the main control MPU 51 shifts to game control, the game start process (S100 in FIG. 22), the special symbol game process (S200), the special electric accessory game process (S300), the normal symbol game process (S400), and the normal electric motor An accessory game process (S500) is executed.

[Game start processing]
Next, the flow of the game start process executed by the main control MPU 51 in S100 of FIG. 22 will be described with reference to the drawings.
FIG. 23 is a flowchart showing the flow of the game start process executed by the main control MPU 51, and FIG. 24 is a flowchart showing the continuation of the game start process shown in FIG.

  The main control MPU 51 transmits the command stored in the command transmission buffer to the video / audio control board 70, the effect control board 400, and the payout control board 60 (S101 in FIG. 23). Subsequently, information of each switch such as the first start port switch 21a and the second start port switch 27a electrically connected to the main control board 50 other than the RAM erase switch 94a is read (S102).

  Subsequently, the state of each read switch is determined, and the determination result is stored in the main control work RAM 53 as switch detection information (S103). For example, when using a switch whose output voltage changes from high level to low level when a game ball is detected (for example, a through-type proximity switch), it is determined that the output voltage has changed from high level to low level. The determination result is stored in the main control work RAM 53 as switch detection information (for example, binary data 1).

  Subsequently, among the random numbers shown in FIG. 15, 1 is added to each of the random numbers used by the main control MPU 51 to update (S104). Subsequently, the switch detection information stored in the main control work RAM 53 in the previous S103 is referred to and it is determined whether or not a winning is detected (S105). If it is determined that a winning is detected (S105: Yes), the switch detection information is stored in the main control work RAM 53 as winning detection information (S106). Subsequently, it is determined whether or not the winning detection information stored in S106 is 0 (S107). If it is determined that it is not 0 (S107: No), a command for storing a command to be transmitted to the payout control board 60 A prize ball number command for paying out the number of prize balls corresponding to the winning detection information is stored in the transmission buffer (S108). For example, if it is determined that one piece of winning detection information for paying out five prize balls is stored (S107: No), a command transmission buffer is used for commanding the number of prize balls for instructing five prize balls to be paid out. (S108).

  Subsequently, it is determined whether or not there is a game ball to be paid out, that is, whether or not the ball is out of play (S109). This determination is made based on whether or not a ball-out condition command is received from the payout control board 60. Here, when it is determined that the ball is out of state (S109: Yes), the ball transmission abnormality command is stored in the command transmission buffer for storing the command to be transmitted to the effect control board 400 (S110), When it is determined that the ball is not in a cut state (S109: No), a normal ball cut command is stored in the command transmission buffer (S111).

  Subsequently, it is determined whether or not the lower tray 7 is full of prize balls (S112). This determination is made based on whether or not a lower tray full signal is received from the lower tray full switch 7b (FIG. 12) via the dispensing control board 60. If it is determined that the base plate 7 is full (S112: Yes), the base plate full error command is stored in the command transmission buffer for storing a command to be transmitted to the image / audio control MPU 71 (S113). . If it is determined in S112 that the lower tray 7 is not full (S112: No), the lower base full command is stored in the command transmission buffer (S114).

  The lower tray full command, the lower full tray command, and the full winning prize command are transmitted to the image / audio control MPU 71 via the effect control board 400 in S101 and further to the payout control MPU 61. Subsequently, it is determined whether or not the door (glass frame set 3) or the frame (front frame set 2) is in an open state (S117 in FIG. 24). This determination is made based on whether a door / frame opening command is received from the payout control board 60. If it is determined that the door or frame is open (S117: Yes), the door / frame open command is stored in the command transmission buffer (S118), and it is determined that the frame or door is not open. In this case (S117: No), the door / frame closed state command is stored in the command transmission buffer (S119).

  Subsequently, it is determined whether or not a prize ball is in an abnormal state, such as a state where there is no prize ball to be paid out, or a situation where a prize ball cannot be paid out due to a ball jam (S120). This determination is made based on whether or not a ball-out command is received from the payout control board 60. If it is determined that the prize ball is abnormal (S120: Yes), the prize ball abnormality command is stored in the command transmission buffer (S121), and if it is determined that the prize ball is not abnormal (S120: No). ), The winning ball normal command is stored (S122). Subsequently, the process proceeds to special symbol game processing.

[Special design game processing]
Next, the flow of the special symbol game process executed by the main control MPU 51 in S200 of FIG. 22 will be described with reference to the drawings.
FIG. 25 is a flowchart showing the flow of the special symbol game process executed by the main control MPU 51, and FIG. 26 is a flowchart showing the continuation of the special symbol game process shown in FIG. Here, a special symbol game process when a game ball wins the first start port 21 will be described.

  The main control MPU 51 determines whether or not the game ball has won the first start port 21 (S201 in FIG. 25). If it is determined that the game ball has been won (S201: Yes), the special symbol holding number U1 is 4. It is determined whether it is less than the number (S202). If it is determined that the number is less than four (S202: Yes), the jackpot determination random number R3 and the jackpot symbol random number R5 are acquired from each random number counter and stored in the main control work RAM 53 (S203). ). Subsequently, 1 is added to the special symbol holding number U (S204).

  Subsequently, it is determined whether or not the first variable winning device 24 or the second variable winning device 25 (FIG. 10 (a)) is in operation, that is, whether or not the big hit game is in operation (S205). If it is determined that it is not (S205: No), it is determined whether or not the special symbol display device 31 (FIG. 10B) is changing the special symbol (S206). If it is determined that the special symbol is not changing (S206: No), it is determined whether or not the special symbol holding number U1 is 0 (S207).

  Here, when it is determined that the special symbol holding number U1 is not 0 (S207: No), it is determined whether or not the gaming state is a probability variation gaming state (S208), and it is determined that the probability variation gaming state is present. (S208: Yes), the jackpot determination of the probability variation gaming state is performed (S209). That is, the jackpot determination random number acquired in the previous S203 is compared with the jackpot value set in the probability variation gaming state of the jackpot value table 52a (FIG. 16), and there is a jackpot value that matches the jackpot determination random number. If it is determined to be a big hit, if it does not exist, it is determined to be lost. For example, if the big hit determination random number is 7, there is a big hit value 7 corresponding to the big hit determination random number, so it is determined that it is a big hit, and if the big hit determination random number is 8, there is no big hit value matching it. Judge as lost.

  If it is determined in S208 that the game state is not the probability change game state (S208: No), a big hit determination in the normal game state is performed (S210). That is, the jackpot determination random number acquired in the previous S203 is compared with the jackpot value set in the normal gaming state of the jackpot value table 52a (FIG. 16), and there is a jackpot value that matches the jackpot determination random number. If it is determined to be a big hit, if it does not exist, it is determined to be lost. For example, if the big hit determination random number is 71, it is determined that there is a big hit value 71 that matches it, so that it is determined as a big hit. If the big hit determination random number is 72, there is no big hit value that matches it. Judge as lost.

  Subsequently, it is determined whether or not the result of the big hit determination in S209 or S210 is a big hit (S211). If it is determined that the big hit is made (S211: Yes), it is determined whether or not it is a probable big hit (S212). For example, if the big hit random number that has been determined to be a big hit in S211 is a specific big hit random number, it is determined to be a promiscuous big hit (S212: Yes). The probability of determining the probability variation big hit can be arbitrarily set, such as 80% or 100%.

  Here, when it is determined that the probability variation big hit (S212: Yes), the probability variation big hit flag indicating that the probability variation big hit is determined is turned on (S213), and when it is determined that the probability variation big hit is not (S212: No), the probability variation is determined. A normal big hit flag indicating that it is not a big hit, that is, a normal big hit is turned on (S214). Subsequently, the probability variation gaming state is terminated and returned to the normal gaming state (S215). Subsequently, the variation pattern of the special symbol is determined by lottery (S216 in FIG. 26), and the variation time set in the determined variation pattern of the special symbol is set (S217).

  Subsequently, each random number acquired in the previous S203, each determination result such as jackpot determination and probability variation jackpot determination, and an effect instruction command are transmitted to the image / audio control MPU 71 (S218). The effect instruction command is a command for causing an effect to be generated by the LED and the speakers 10 to 12 arranged on the effect display 30 and the game board 5. Subsequently, the variation of the special symbol is started (S219).

  Subsequently, measurement of the variation time set in S217 is started (S220). This variation time is the time required from when the special symbol starts to change until it stops, and at the same time, the time required for the effect indicator 30 to start after the change / effect pattern is displayed. Subsequently, 1 is subtracted from the special symbol holding number U1 (S221).

  Subsequently, it is determined whether or not the gaming state is a probability variation gaming state (S222). If it is determined that the gaming state is a probability variation gaming state (S222: Yes), the number of rotations (number of variations) C of the special symbol is set to 1. Addition is performed (S223). This rotational speed C is equal to the rotational speed (number of fluctuations) of the effect symbol. Subsequently, it is determined whether or not the rotation speed C has reached 70 times, which is the end of the period during which the probability variation gaming state continues (S224). If it is determined that the rotation speed C has reached 70 times (S224: Yes), The probability variation gaming state is terminated, and the normal gaming state is restored (S225).

  Then, when executing the special symbol game process in the next cycle, if it is determined that the special symbol is changing in S206 of FIG. 25 (S206: Yes), it is determined whether or not the variation time has elapsed (FIG. 25). 26 (S226), if it is determined that the time has elapsed (S226: Yes), the variation of the special symbol and the effect symbol is stopped (S227). Subsequently, it is determined whether or not the big hit symbol is confirmed and displayed (S228). If it is determined that the big hit symbol is confirmed and displayed (S228: Yes), the big hit game, that is, the special electric accessory game process is started (S229). .

[Special electric equipment game processing]
Next, the flow of the special electric accessory game process executed by the main control MPU 51 in S300 of FIG. 22 will be described with reference to the drawings.
FIG. 27 is a flowchart showing the flow of the special electric accessory game process executed by the main control MPU 51.

  Here, the case where the first big winning opening 24a is opened and closed will be described. Also, a round from the opening of the first grand prize winning opening 24a to the closing is defined as one round, and a game from the start of the first round to the end of the final round is referred to as a big hit game. The maximum number of winnings that can be won in the first big winning opening 24a per round is nine, and the maximum opening time that can be opened in the first big winning opening 24a per round is 30 seconds. Furthermore, the maximum number of rounds that can be executed is 16 rounds.

  The main control MPU 51 determines whether or not the probability variation big hit flag or the normal big hit flag indicating the result of the probability variation big hit determination is on (S301), and if it is determined to be on (S301: Yes), the probability variation big hit flag is determined. The big hit flag or the normal big hit flag is turned off (S302). Subsequently, the executable round number R is set to 16 (S303), and 1 is subtracted from the round number R (S304). The round number R is transmitted to the image / audio control MPU 71.

  Subsequently, the winning number n to the first big winning opening 24a per round is reset to 0, and the opening time t of the first big winning opening 24a per round is set (S305). Subsequently, the first big prize opening solenoid 24b (FIG. 12) is driven to open the first big prize opening 24a (S306), and the measurement of the opening time t is started (S307). Subsequently, based on the change in the signal output from the first grand prize opening switch 24c (FIG. 12), it is determined whether or not the game ball has won the first big prize opening 24a (S308).

  Here, if it is determined that the game ball has won the first grand prize opening 24a (S308: Yes), 1 is added to the winning number n (S309). Subsequently, it is determined whether or not the winning number n is 9 or more (S310). When it is determined that the winning number n is not 9 or more (S310: No), the opening time t is 30 seconds. Is determined (S311). Here, when it is determined that the opening time t has not reached 30 seconds (S311: No), the process proceeds to the next process.

  When the special electric accessory processing is executed in the next cycle, since the probability variation big hit flag or the normal big hit flag is turned off in the previous S302, in S301, the probability variation big hit flag or the normal big hit flag is not turned on. Determine (S301: No). Subsequently, it is determined whether or not a round end flag indicating that the round has ended is turned on (S312). At this stage, since the round has not ended yet, the round end flag is not turned on. Determine (S312: No).

  Subsequently, S308 to S311, S301, and S312 are repeatedly executed. When it is determined in S310 that the winning number n is 9 or more (S310: Yes), the round end flag is turned on (S314). If it is determined in S311 that the opening time t has reached 30 seconds (S311: Yes), the round end flag is turned on (S314). In other words, the round ends when either the condition that the winning number n is 9 or more or the condition that the opening time t reaches 30 seconds is satisfied.

  Subsequently, it is determined whether or not the number of rounds R has become 0 (S315). If it is determined that the number of rounds R has not become 0 (S315: No), the round end flag is set in S312 in the next cycle. It is determined that the jackpot game is ended (S312: Yes), and it is determined whether or not the jackpot game end flag indicating that the jackpot game has ended (S313). If it is determined in S315 that the number of rounds R has become 0 (S315: Yes), the big hit game end flag is turned on (S316), and it is determined whether or not the probability variable big hit flag is turned on (S317). If it is determined that the probability variation jackpot flag is on (S317: Yes), the gaming state is changed to the probability variation gaming state (S318), and the probability variation jackpot flag is turned off (S319). If it is determined in S317 that the probability variation big hit flag is not turned on (S317: No), the normal big hit flag is turned off (S319).

[Normal design game processing]
Next, the flow of the normal symbol game process executed by the main control MPU 51 in S400 of FIG. 22 will be described with reference to the drawings.
FIG. 28 is a flowchart showing the flow of the normal symbol game process executed by the main control MPU 51, and FIG. 29 is a flowchart showing the continuation of the normal symbol game process shown in FIG.

  The main control MPU 51 determines whether or not the game ball has passed through the gate 23 (S401 in FIG. 28). If it is determined that the game ball has passed (S401: Yes), the normal symbol holding number Q1 is less than four. It is determined whether or not there is (S402). If it is determined that the number is less than four (S402: Yes), the hit determination random number is acquired from the hit determination random number counter and stored in the main control work RAM 53 (S403). Subsequently, 1 is added to the normal symbol holding number Q1 (S404).

  Subsequently, it is determined whether or not the normal electric accessory 27 (FIG. 8) is in operation (S405). If it is determined that the normal electric accessory 27 (FIG. 8) is not in operation (S405: No), the normal symbol display device 33 (FIG. It is determined whether (b)) is changing the normal symbol (S406). If it is determined that the normal symbol is not fluctuating (S406: No), it is determined whether or not the normal symbol hold count Q1 is 0 (S407).

  Here, when it is determined that the normal symbol holding number Q1 is not 0 (S407: No), a hit determination is performed (S408). That is, the hit determination random number obtained in the previous S403 is compared with the hit value set in the hit value table (not shown), and if there is a hit value that matches the hit determination random number, If it does not exist, it is determined to be lost. Subsequently, it is determined whether or not the result of the hit determination is a win (S409). If it is determined that the hit is made (S409: Yes), a hit flag indicating that the hit is determined is turned on (S410). Subsequently, the variation pattern of the normal symbol is determined by lottery (S411).

  Subsequently, the variation time set in the variation pattern of the normal symbol determined in S411 is set (S412). Subsequently, each random number acquired in the previous S403, the result of the hit determination, and the effect instruction command are transmitted to the image / audio control MPU 71 (S413 in FIG. 29). The effect instruction command is a command for causing the normal symbol display device 33 to change the normal symbol. Subsequently, the variation of the normal symbol is started (S414), and the measurement of the variation time set in S412 is started (S415). Subsequently, 1 is subtracted from the normal symbol holding number Q1 (S416).

  Then, when executing the normal symbol game process in the next cycle, if it is determined in S406 in FIG. 28 that the normal symbol is changing (S406: Yes), it is determined whether or not the change time has elapsed (FIG. 28). 29 (S417), if it is determined that the time has passed (S417: Yes), the fluctuation of the normal symbol is stopped (S418).

[Normal electric game game processing]
Next, the flow of the ordinary electric accessory game process executed by the main control MPU 51 in S500 of FIG. 22 will be described with reference to the flowchart of FIG.

  The main control MPU 51 determines whether or not the time t2 during which the normal electric accessory 27 opens the opening / closing blade piece 27c (FIG. 8) is being measured (S501), and when it is determined that the measurement is not being performed. (S501: No), it is determined whether or not the winning flag is on by executing S410 (FIG. 28) of the normal symbol game process (S502). Here, when it is determined that the hit flag is on (S502: Yes), the normal electric accessory solenoid 27b (FIG. 12) is operated to open the opening / closing blade piece 27c (S503). Subsequently, measurement of the time t2 during which the opening / closing blade piece 27c is opened is started (S504).

  When it is determined that the time t2 is being measured when executing the ordinary electric accessory game process in the next cycle (S501: Yes), it is determined whether or not the time t2 has reached 1 second (S505). ). Here, when it is determined that the time t2 has reached 1 second (S505: Yes), the operation of the ordinary electric accessory solenoid 27b is stopped to close the opening / closing blade piece 27c (S506). Subsequently, the hit flag is turned off (S507).

[Production control]
Next, main processing (effect control) executed by the video / audio control MPU 71 during the game will be described with reference to the flowchart shown in FIG.

  The image / audio control MPU 71 receives a command received by the main control MPU 51 (S600), image processing for displaying various images on the effect display 30 (S700), and various sounds from the speakers 10-12. Audio processing (S800), LED processing (S900) for controlling the turning on and off of various LEDs arranged in the front frame set 2 and the game board 5, etc., the volume of the bass is automatically based on the ambient noise level Volume automatic adjustment processing (S1000) etc. to adjust automatically is performed.

[Command reception processing]
Next, the flow of command reception processing executed by the image / audio control MPU 71 will be described with reference to the flowchart shown in FIG.

  The image / audio control MPU 71 determines whether or not the command transmitted by the main control MPU 51 has been received (S601). If it is determined that the command has been received (S601: Yes), the received command is used for image / audio control. The data is stored in the work RAM 73 (S602). Subsequently, the type and contents of the command stored in the image / sound control work RAM 73 are analyzed (S603), and the analysis result is stored in the image / sound control work RAM 73 (S604).

[Image processing]
Next, the flow of image processing executed by the image / audio control MPU 71 will be described with reference to the flowchart shown in FIG.

  The MPU 71 for image and sound control determines whether or not the effect display 30 is variably displaying the effect symbol (S701), and when it is determined that the effect indicator 30 is not variably displaying the effect symbol (S701: No). ) Based on the analysis result stored in the audio / video control work RAM 73 in S604 of the previous command processing, it is determined whether or not the command transmitted by the main control MPU 51 is an effect instruction command (S702). Here, when it is determined that the command transmitted by the main control MPU 51 is an effect instruction command (S702: Yes), the reach selection random number R7 and the first variation group selection random number R8 are obtained from the random number counter, respectively. Is stored in the image / audio control work RAM 73 (S703).

  Subsequently, as a result of each determination such as the jackpot determination transmitted from the main control MPU 51, the variation time and each random number, the reach selection random number R7 and the first variation group selection random number R8 stored in the image sound control work RAM 73 in S703. Based on the above, a variation / effect pattern is determined (S704). Subsequently, the variation time of the effect symbol in the determined variation / effect pattern is set (S705), the image processing LSI 76 is controlled, and the variation / effect pattern determined in S704 is displayed on the effect display 30 (S706). Subsequently, measurement of the variation time set in S705 is started (S707).

  Then, when the image processing is executed in the next cycle, it is determined whether or not the effect symbol is being displayed in a variable manner (S701). If it is determined that the effect symbol is being displayed (S701: Yes), the measurement is started in the previous S707. It is determined whether the changed time has elapsed (S708). Here, when it is determined that the variation time has not elapsed (S708: No), it is determined whether it is the timing for performing the button effect (S709). If it is determined that it is time to perform the button effect (S709: Yes), the button effect process is executed (S710).

  If it is determined in S709 that it is not time to perform a button effect (S709: No), it is determined whether it is time to reach (S711), and if it is determined that it is time to reach ( (S711: Yes), a reach effect is performed (S712). If it is determined in S708 that the fluctuation time has elapsed (S708: Yes), a big hit symbol or a lost symbol is fixedly displayed as a stop effect symbol (S713). If the variation / effect pattern determined in S704 does not include a button effect, a negative determination is made in S709. If the change / effect pattern determined in S704 does not include a reach, the determination is negative in S711. Judge and move to next process.

[Sound effect automatic adjustment processing]
Next, acoustic effect automatic adjustment processing executed by the image / audio control MPU 71 will be described with reference to FIGS. 34 and 35. FIG.
FIG. 34 is a flowchart showing the flow of the acoustic effect automatic adjustment process executed by the image / audio control MPU 71. FIG. 35 is an explanatory diagram of the sound effect adjustment table 72c.

  The image / audio control MPU 71 adjusts the volume Vb of the low sound reproduced by the lower speaker 12 using the acoustic effect adjustment table 72c shown in FIG. The sound effect adjustment table 72c is configured by associating the noise level Va with the adjustment value of the bass sound volume Vb. Vs shown in the adjustment value of the bass sound volume Vb indicates a standard bass sound volume. For example, if the noise level Va measured based on the output signal of the microphone 300 is less than 75 dB, the image / audio control MPU 71 selects the adjustment value (Vs−2) of the low sound volume Vb from the volume adjustment table 72c. . When the noise level Va is 80 dB or more and less than 85 dB, the adjustment value Vs of the bass sound volume Vb is selected from the sound volume adjustment table 72c. Further, when the noise level Va is 90 dB or more, the adjustment value (Vs + 2) of the low sound volume Vb is selected from the sound volume adjustment table 72c. The range of 80 dB or more and less than 85 dB is the threshold value, and the low sound volume Vb is adjusted so as to decrease as the ambient noise level Va becomes smaller than the threshold value, and the low sound volume Vb becomes smaller as the ambient noise level Va becomes larger than the threshold value. Adjust to be larger.

  The image / audio control MPU 71 measures the noise level Va based on the output signal of the microphone 300 (S1001). Subsequently, it is determined whether or not the noise level Va measured in S1001 is less than 75 dB (S1002). If it is determined that it is less than 75 dB (S1002: Yes), the bass corresponding to the noise level Va less than 75 dB is determined. The adjustment value (Vs-2) of the volume Vb is selected from the sound effect adjustment table 72c, and the bass volume Vb of the speaker 12 of the pachinko machine 1 is adjusted to (Vs-2) (S1003). That is, since the noise level Va around the pachinko machine C is less than 75 dB and the lowest level, the bass volume Vb is adjusted to the lowest volume (Vs-2). Thereby, there is no possibility that the music reproduced by the speakers 10 to 12 may be heard in a mess.

  If it is determined in S1002 that the noise level Va is not less than 75 dB (S1002: No), it is determined whether the noise level Va is 75 dB or more and less than 80 dB (S1004). Here, when it is determined that the noise level Va is 75 dB or more and less than 80 dB (S1004: Yes), the adjustment value (Vs-1) of the bass sound volume Vb corresponding to the noise level Va of 75 dB or more and less than 80 dB is adjusted to the acoustic effect. The selection is made from the table 72c, and the bass volume Vb of the speaker 12 of the pachinko machine 1 is adjusted to (Vs-1) (S1005). That is, since the noise level Va around the pachinko machine C is not less than 75 dB and less than 80 dB and is the second lowest level from the lowest, the bass volume Vb is adjusted to the second lowest bass volume (Vs-2). . Thereby, it is possible to prevent the music reproduced by the speakers 10 to 12 from being confused.

  In S1004, when it is determined that the noise level Va is not 75 dB or more and less than 80 dB (S1004: No), it is determined whether the noise level Va is 80 dB or more and less than 85 dB (S1006). Here, when it is determined that the noise level Va is 80 dB or more and less than 85 dB (S1006: Yes), the adjustment value Vs of the bass sound volume Vb corresponding to the noise level Va of 80 dB or more and less than 85 dB is selected from the sound effect adjustment table 72c. Then, the bass volume Vb of the speaker 12 of the pachinko machine 1 is adjusted to Vs (S1007). That is, since the noise level Va around the pachinko machine C is 80 dB or more and less than 85 dB and is a standard level, the bass volume Vb is adjusted to the standard volume Vs. Thereby, the music reproduced by the speakers 10 to 12 can be prevented from being scrambled or hard to hear by the music from the surrounding pachinko machine.

  In S1006, when it is determined that the noise level Va is not 80 dB or more and less than 85 dB (S1006: No), it is determined whether the noise level Va is 85 dB or more and less than 90 dB (S1008). Here, when it is determined that the noise level Va is 85 dB or more and less than 90 dB (S1008: Yes), the adjustment value (Vs + 1) of the bass sound volume Vb corresponding to the noise level Va of 85 dB or more and less than 90 dB is used as the sound effect adjustment table 72c. And the bass volume Vb of the speaker 12 of the pachinko machine 1 is adjusted to (Vs + 1) (S1009). That is, since the noise level Va around the pachinko machine C is 85 dB or more and less than 90 dB and is one level higher than the standard, the bass volume Vb is adjusted to a volume (Vs + 1) that is one level higher than the standard volume Vs. Thereby, it is possible to prevent the music reproduced by the speakers 10 to 12 from being difficult to hear due to the music that comes from the surrounding pachinko machine.

  In S1008, when it is determined that the noise level Va is not 85 dB or more and less than 90 dB (S1008: No), it is determined whether the noise level Va is 90 dB or more (S1010). Here, when it is determined that the noise level Va is 90 dB or more (S1010: Yes), the adjustment value (Vs + 2) of the bass sound volume Vb corresponding to the noise level Va of 90 dB or more is selected from the sound effect adjustment table 72c, The bass volume Vb of the speaker 12 of the pachinko machine 1 is adjusted to (Vs + 2) (S1011). That is, since the noise level Va around the pachinko machine C is 90 dB or higher and the highest level, the bass volume Vb is adjusted to the highest volume (Vs + 2). Thereby, it is possible to prevent the music reproduced by the speakers 10 to 12 from being difficult to hear due to the music that comes from the surrounding pachinko machine.

[Effect of the first embodiment]
If the pachinko machine 1 according to the first embodiment described above is implemented, the loudspeaker volume Vb of the loudspeaker 12 that reproduces bass can be adjusted to a larger volume as the ambient noise level Va becomes larger than the threshold. It makes it easy to listen to music to be reproduced. In addition, as the ambient noise level Va becomes smaller than the threshold value 0, the low sound volume Vb of the speaker 12 that reproduces the low sound can be adjusted to a low sound volume, so that the music reproduced by the speakers 10 to 12 does not feel crowded. .
That is, it is possible to realize a pachinko machine in which music reproduced by the speakers 10 to 12 does not feel confused or difficult to hear depending on the ambient noise level.

Second Embodiment
Next explained is the second embodiment of the invention.
In the pachinko machine of this embodiment, by changing the content of the surround effect corresponding to the ambient noise level, the music played by the speakers 10 to 12 may feel confused or difficult to hear depending on the ambient noise level. It is characterized by not having.
FIG. 36 is an explanatory diagram of the sound effect adjustment table 72d provided in the pachinko machine according to this embodiment, and FIG. 37 illustrates the automatic sound effect executed by the image / audio control MPU 71 provided in the pachinko machine according to this embodiment. It is a flowchart which shows the flow of the adjustment process 2. FIG. The pachinko machine of this embodiment has the same configuration and the same structure as the pachinko machine 1 of the first embodiment except for the configuration of the acoustic effect adjustment table 72d and the flow of the acoustic effect automatic adjustment process 2 executed by the image / audio control MPU 71. Since it is a function, the same code | symbol is used about the same structure and description is abbreviate | omitted.

  The right speaker 10 and the left speaker 11 provided in the pachinko machine 1 of this embodiment function as a 2ch (channel) speaker, and the lower speaker 12 functions as a woofer. That is, the speakers 10 to 12 constitute a 2.1ch (channel) virtual (pseudo) surround speaker.

  As shown in FIG. 36, the acoustic effect adjustment table 72d is configured by associating the ambient noise level Va with the adjustment value of the surround phase difference Ph. When the audio / video control MPU 71 selects the phase difference Ph corresponding to the measured ambient noise level Va from the acoustic effect adjustment table 72d and outputs the selected phase difference Ph to the surround IC 82 (FIG. 14), the surround IC 82 Then, the phase difference of the digital signal output to the volume setting circuit 83 is adjusted to the phase difference Ph instructed from the image / audio control MPU 71. Thereby, the phase difference of the signal output from the volume setting circuit 83 to the digital amplifier 84 is adjusted to Ph, and the phase difference of the sound reproduced by the right speaker 10 and the left speaker 11 is adjusted to Ph. In other words, the spread of the sound reproduced by the right speaker 10 and the left speaker 11 changes according to the surrounding noise level Va.

  The image / audio control MPU 71 measures the noise level Va based on the output signal of the microphone 300 (S1001). Subsequently, it is determined whether or not the noise level Va measured in S1001 is less than 75 dB (S1002). If it is determined that it is less than 75 dB (S1002: Yes), the surround corresponding to the noise level Va less than 75 dB is determined. The adjustment value Ps of the phase difference Ph is selected from the acoustic effect adjustment table 72d, and the phase difference Ph set by the surround IC 82 is adjusted to Ps (S1003). That is, since the noise level Va around the pachinko machine C is less than 75 dB and the lowest level, the phase difference Ph is adjusted to the minimum phase difference Ps. Thereby, there is no possibility that the sound reproduced by the speakers 10 to 12 may be heard in a mess.

  If it is determined in S1002 that the noise level Va is not less than 75 dB (S1002: No), it is determined whether the noise level Va is 75 dB or more and less than 80 dB (S1004). Here, when it is determined that the noise level Va is 75 dB or more and less than 80 dB (S1004: Yes), an adjustment value (Ps + 1) corresponding to the noise level Va of 75 dB or more and less than 80 dB is selected from the sound effect adjustment table 72d, The phase difference Ph set by the surround IC 82 is adjusted to (Ps + 1) (S1005). That is, since the noise level Va around the pachinko machine C is 75 dB or more and less than 80 dB and is the second lowest level from the lowest, the phase difference Ph is larger by one step than the minimum phase difference Ps (Ps + 1)) Adjust to. Thereby, it is possible to prevent the sound reproduced by the speakers 10 to 12 from being confused.

  In S1004, when it is determined that the noise level Va is not 75 dB or more and less than 80 dB (S1004: No), it is determined whether the noise level Va is 80 dB or more and less than 85 dB (S1006). Here, when it is determined that the noise level Va is 80 dB or more and less than 85 dB (S1006: Yes), an adjustment value (Ps + 2) corresponding to the noise level Va of 80 dB or more and less than 85 dB is selected from the sound effect adjustment table 72d, The phase difference Ph set by the surround IC 82 is adjusted to (Ps + 2) (S1007). That is, since the noise level Va around the pachinko machine C is 80 dB or more and less than 85 dB and is a standard level, the phase difference Ph is adjusted to a phase difference (Ps + 2) that is two steps larger than the minimum phase difference Ps. Thereby, the sound reproduced by the speakers 10 to 12 can be prevented from being confused or difficult to hear by the sound emitted from the surrounding pachinko machine.

  In S1006, when it is determined that the noise level Va is not 80 dB or more and less than 85 dB (S1006: No), it is determined whether the noise level Va is 85 dB or more and less than 90 dB (S1008). Here, when it is determined that the noise level Va is 85 dB or more and less than 90 dB (S1008: Yes), an adjustment value (Ps + 3) corresponding to the noise level Va of 85 dB or more and less than 90 dB is selected from the sound effect adjustment table 72d, The phase difference Ph set by the surround IC 82 is adjusted to (Ps + 3) (S1009). That is, since the noise level Va around the pachinko machine C is 85 dB or more and less than 90 dB and is one level higher than the standard, the phase difference Ph is adjusted to a volume (Ps + 3) that is three steps larger than the minimum phase difference Ps. . Thereby, the sound reproduced by the speakers 10 to 12 can be prevented from becoming difficult to hear due to the sound emitted from the surrounding pachinko machine.

  In S1008, when it is determined that the noise level Va is not 85 dB or more and less than 90 dB (S1008: No), it is determined whether the noise level Va is 90 dB or more (S1010). If it is determined that the noise level Va is 90 dB or more (S1010: Yes), an adjustment value (Ps + 4) corresponding to the noise level Va of 90 dB or more is selected from the acoustic effect adjustment table 72d, and the surround IC 82 is set. The phase difference Ph to be adjusted is adjusted to (Ps + 4) (S1011). That is, since the noise level Va around the pachinko machine C is 90 dB or higher and the highest level, the phase difference Ph is adjusted to the largest phase difference (Ps + 4). Thereby, the sound reproduced by the speakers 10 to 12 can be prevented from becoming difficult to hear due to the sound emitted from the surrounding pachinko machine.

[Effects of Second Embodiment]
If the pachinko machine 1 of the second embodiment described above is implemented, the surround produced by the speakers 10 and 11 by adjusting the phase difference Ph of the speakers 10 and 11 to a larger phase difference as the ambient noise level Va becomes larger than the threshold value. Since an effect can be enlarged, it becomes easy to hear the sound reproduced by the speakers 10 to 12. Moreover, the surround effect produced by the speakers 10 and 11 can be reduced by adjusting the phase difference Ph of the speakers 10 and 11 to a smaller phase difference as the ambient noise level Va becomes smaller than the threshold value 0. Twelve music to play does not feel crazy.
That is, it is possible to realize a pachinko machine in which music reproduced by the speakers 10 to 12 does not feel confused or difficult to hear depending on the ambient noise level.
