Description

  The present invention provides a liquid crystal display device that displays a moving image when a game ball is received in a specific game ball receiving port, and a prize winning port when the image when the moving image is stopped is a specific image. The present invention relates to a pachinko machine provided with a winning device for opening and closing the door.

A conventional pachinko machine will be described with reference to the drawings.
40 is a front view showing a state in which a plurality of conventional pachinko machines are arranged, and FIG. 41 is a plan view of the pachinko machine shown in FIG. 40 and the player. FIG. 42 is a front view of the pachinko machine shown in FIG.

  In the pachinko hall, a plurality of pachinko machines 700 are arranged across the passage. As shown in FIG. 41, each pachinko machine 700 is arranged so that the front faces the passage side, and the players Y1 to Y3 are each sitting on a chair placed in front of the pachinko machine 700 and playing I do.

  As shown in FIG. 42, 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 launch device that launches the game ball to the flow area, and a game A starting port 703, a liquid crystal display device 704, and a variable winning device 706 arranged on the board 702, and an upper tray 705 for storing a winning ball and a rental ball 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. The liquid crystal display device 704 starts displaying a moving image when the game ball wins the start opening 703, 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 liquid crystal display device 704 includes a symbol moving image that displays the symbols in a variable manner and a background moving image that is displayed in 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. There is also a display mode that displays as above. A display mode in which each symbol constituting the symbol row changes in the display area as described above is called symbol variation. In addition, while the liquid crystal display device 704 displays a moving image, a speaker (not shown) provided in the pachinko machine 700 outputs music and sound effects.

  When a predetermined time elapses after the liquid crystal 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 liquid crystal display device 704 starts displaying a moving image until the big hit symbol or the lost symbol is displayed is counted as one variation of the symbol.

  When the liquid crystal display device 704 confirms and displays the big hit symbol, a big hit occurs, and the variable winning device 706 opens the opening / closing member 707 and opens the big winning opening 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 plurality of rounds (for example, a maximum of 14 rounds) are executed from the opening of the special winning opening 708 to the closing thereof, and the player can acquire a large number of winning balls during that period. Hereinafter, the game from the start of the first round to the end of the final round is referred to as a jackpot game.

  In addition, the variation patterns from when the liquid crystal display device 704 starts the variation of the symbol until the big hit symbol or the lost symbol is fixedly displayed include a variation pattern called a normal variation and a reach variation. 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 where the symbol is fluctuating. 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 addition, the reach variation pattern includes a low probability and a high probability of appearing. The reach fluctuation pattern with the lower probability of appearing has higher expectation for the occurrence of jackpot. Here, the degree of expectation for the occurrence of a big hit is the appearance of the reach fluctuation pattern that leads to the big hit with respect to the total appearance rate that is the sum of the appearance rate of the reach fluctuation pattern that leads to the big hit and the appearance rate of the reach fluctuation pattern that leads to the loss. It shows the rate ratio.

  By the way, since the liquid crystal display device 704 provided in the conventional pachinko machine 700 has a wide screen viewing angle, the display content of the screen can be understood even from a position shifted laterally from the front of the liquid crystal display device 704. Moreover, as shown in FIG. 41, the arrangement interval of the pachinko machine 700 is narrow. Therefore, there is a possibility that an adjacent player looks into the screen of the liquid crystal display device 704. For example, the liquid crystal display device 704 provided in the central pachinko machine 700 in which the player Y2 is playing may be looked into by the adjacent players Y1 and Y2. The arrows indicated by reference signs F1 to F3 in the figure are the line of sight of each player.

  In addition, since the interval between the pachinko machines 700 is narrow, the sound generated from the adjacent pachinko machine can be heard. In particular, when the liquid crystal display device 704 displays a reach fluctuation pattern with a high expectation for occurrence of a big hit, characteristic music that does not occur in other fluctuation patterns flows. When heard from a pachinko machine, the adjacent player can also see that the pachinko machine displays a reach variation pattern with high expectations for the occurrence of a big hit. For this reason, there is a risk that the next player who is interested in the possibility of a big hit in the next pachinko machine will look into the screen.

However, the act of looking into the screen by the next player is not very pleasant, and it is annoying for a player who enjoys concentrating on the game.
In addition, it is possible to arrange things such as peep prevention plates on both sides of the screen so that they are not always visible from the next, but the design of the pachinko machine will be damaged.

  Therefore, the present invention has been made to solve the above-described problem, and when there is a possibility that the liquid crystal display device displays a specific image, it is difficult for the next player to see the display content. Therefore, it is an object of the present invention to realize a pachinko machine that can eliminate an act of looking into the screen by an adjacent player.

In order to achieve the above object, in the invention according to claim 1 of this application, a game board (5) in which a falling area of the game ball (P) is formed, and a launching device ( 4f), a plurality of game ball receiving openings (17 to 23) provided in the game area, random number generating means for generating a random number (R3), and a game ball fired by the launching device is a specific game ball Random number acquisition means (S204) for acquiring the random number generated by the random number generation means when received in the receiving ports (21, 22), and determining whether the hit or loss is based on the random number acquired by the random number acquisition means Big hit determination means (S211) and display of a moving image is started when a game ball fired by the launching device is received in the specific game ball receiving port, and after a predetermined time has elapsed from the start, the jackpot determination Means A liquid crystal display device (30) for displaying an image showing a fixed result, a sound reproduction device (10-12) for reproducing sound when the liquid crystal display device is displaying the moving image, and the liquid crystal display device A winning device (24, 25) that opens and closes a big winning opening when an image showing a result of the determination that the big hit determining means has determined to be a big win, and a winning ball when a game ball wins the big winning opening In a pachinko machine (1) provided with a prize ball payout device (38) for taking out,
The liquid crystal display device
The viewing angle of the screen is electrically changed to a wide viewing angle that is easy to see from other players who play with other pachinko machines arranged next to the pachinko machine, and a narrow viewing angle that is difficult to see from the other players. It is configured to be switchable (30b, 30c),
A viewing angle switching device (79) for switching the viewing angle between the wide viewing angle and the narrow viewing angle;
The technical means includes an operation member (9) that operates the viewing angle switching device by a player's operation and switches the viewing angle from the wide viewing angle to the narrow viewing angle.

  In addition, the code | symbol in each said parenthesis shows the correspondence with the specific means as described in embodiment mentioned later.

When the invention according to claim 1 is carried out, the player operates the operation member so that the viewing angle of the screen of the liquid crystal display device is played by another pachinko machine arranged next to the pachinko machine. It is possible to switch to a narrow viewing angle so that it is difficult for the player to see.
Therefore, when there is a possibility that the liquid crystal display device displays a specific image, it is possible to realize a pachinko machine that can eliminate the act of looking into the screen by an adjacent player.

  Moreover, since it is possible to prevent peeping without arranging objects such as peeping prevention plates on both sides of the screen of the liquid crystal display device, the design of the pachinko machine is not impaired.

  One or both of the first variable winning device 24 and the second variable winning device 25 operate depending on the type of jackpot that has occurred. The opening times of the first big prize opening 24a and the second big prize opening 25a differ depending on the type of the big hit that has occurred. In this embodiment, the first grand prize opening 24a is closed when 29.5 seconds have elapsed from the opening or when nine game balls have won the first big prize opening 24a. The second grand prize opening 25a is closed when 0.2 seconds elapses from the opening or when nine game balls enter the second big prize opening 25a. That is, since the opening time of the second big prize opening 25a is extremely short as 0.2 seconds, it is difficult to win the second big prize opening 25a with a big hit when the second big prize opening 25a opens and closes. Can hardly be expected.

As shown in FIG. 9B, on the left side of the left sleeve decoration winning opening 17 of the left side decoration 36 in FIG. 6 (the area surrounded by the broken line indicated by the symbol A in the figure), the special symbol display device 31 and A normal symbol display device 33, a special symbol hold number display device 32, and a normal symbol hold number display device 34 are provided.
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. 9B), and these LEDs are connected to the first start port 21 or the second start port 22. 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 type of jackpot is configured by combining two or more of the maximum number of rounds that can be executed in the jackpot game, the number of rounds without a ball, the normal jackpot, the probability variable jackpot, the probability variable jackpot without a ball 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 (for example, two as shown in FIG. 9B) LEDs, and the emitted color when each LED is lit 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 variation display ends, the combination of the LEDs that are turned on and off turns on the normal symbol. Alternatively, the loss is notified. When the winning normal symbol is confirmed and displayed, the opening / closing wing piece 27c of the ordinary electric accessory 27 is opened, and the winning to the second big winning opening 22 becomes easy.

  When the game ball passes through the gate 23, the normal symbol display device 33 starts to display the fluctuation of the normal symbol. 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.

(Display contents of the production indicator 30)
Here, the display content of the effect display device 30 will be described with reference to the drawings.
FIG. 10A is an explanatory diagram showing a state in which the effect symbol is variably displayed on the effect indicator 30, FIG. 10B is an explanatory diagram showing a state in which 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 that the special symbol display device 31 starts 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, the number of rounds in the big hit game, an image for waiting for a customer to be displayed when no game is played, and the like are displayed.

  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. The variation / direction pattern, jackpot symbol, and lose symbol are determined by lottery using random numbers.

As shown in FIG. 10, 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. Further, depending on the model, there is a combination of a display area in which a plurality of effect symbols are variably displayed in ascending order of numbers and a display area that is variably displayed in descending order of numbers.
The example shown in FIG. 10 (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. 10B, 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, the 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. 10B, 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.
Furthermore, when the display area D2 is about to stop, the display areas D1 to D3 are reduced, the story of the background moving image is expanded, and the big hit symbol or the lost symbol is displayed depending on the result of the story. .

  In this embodiment, a plurality of types of normal variation patterns and a plurality of types of reach variation patterns are set to be selectable. The reach variation pattern includes the normal reach variation pattern, the super reach variation pattern, and the premium reach variation pattern. The super reach variation pattern has a lower appearance rate than the normal reach variation pattern. Appearance rate is lower than the pattern. The reach variation pattern with a lower appearance rate has a higher expectation for jackpot occurrence, and the production in the reach state is elaborate.

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. 10 (c), the effect symbols 7 are fixedly displayed in the display areas D1 to D3, respectively, and “777” as an example of the jackpot symbol is arranged.

  Further, the story and length of the background moving image differ depending on the type of variation / direction pattern. The normal variation pattern is associated with the background moving image of the story corresponding to the variation time of the normal variation pattern, and the reach variation pattern is associated with the background moving image of the story according to the variation time of the reach variation pattern. It has been. In particular, the reach variation pattern having a low appearance rate is associated with a background image of a sophisticated effect for exciting a reach-specific effect. For example, 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 manufacturer.

  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. In addition, among the variation patterns that make up the variation / production pattern, the production design 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 production design is displayed at the center of the screen. 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

  Further, depending on the type of variation / effect pattern, the time required from the start of the display of the variation / effect pattern until the big hit symbol or the lost symbol is determined and displayed, that is, the 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 with lower appearance probability has a longer variation time. For example, the fluctuation time is about 10 seconds for the normal fluctuation pattern, 20 to 30 seconds for the normal reach fluctuation pattern, 60 to 90 seconds for the super reach fluctuation pattern, and 120 to 180 seconds for the premium reach fluctuation pattern.

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.

[Features of pachinko machine 1]
Here, the features of the pachinko machine 1 will be described with reference to the drawings.
FIG. 11 is a timing chart showing the relationship between the start and stop timing of the game, the timing when the effect button is pressed and held, and the viewing angle switching timing.

  The effect display unit 30 is configured so that the viewing angle of the screen can be switched between a wide viewing angle and a narrow viewing angle. In other words, when other players playing a game on other pachinko machines arranged on both sides of the pachinko machine 1 are easy to see when the display content of the effect display 30 is a wide viewing angle, but when the viewing angle is a narrow viewing angle Is configured to be difficult to see. When the player presses the effect button 9 for a long time, the screen of the effect indicator 30 is switched from the wide viewing angle to the narrow viewing angle.

  The effect button 9 is used both as a button for executing the button effect and a button for switching the viewing angle of the screen of the effect display 30 to a narrow viewing angle. When switching, the effect button 9 is long pressed, and when the button effect is executed, the effect button 9 is operated in a short time. For example, the long press is an operation method of continuing the state where the effect button 9 is pressed for 2 seconds or more.

  In the example shown in FIG. 11, when the game is started, the viewing angle of the screen of the effect indicator 30 is a wide viewing angle (t1). When the effect button 9 is pressed for a long time, the viewing angle of the screen of the effect indicator 30 is switched to a narrow viewing angle (t2). And when time Td1 (t3-t4) passes after stopping a game, the viewing angle of the screen of the production | presentation display 30 has returned to the wide viewing angle.

In this way, when the player does not want the next player to look into the content displayed on the effect display 30, the player can press and hold the effect button 9 to widen the viewing angle of the screen of the effect display 30. Since the viewing angle can be switched to the narrow viewing angle, it is possible to make it difficult for an adjacent player to see the content displayed on the effect display 30.
Moreover, since it is possible to prevent peeping without arranging objects such as peeping prevention plates on both sides of the screen of the effect display device 30, there is no possibility that the design of the pachinko machine 1 is impaired.
Furthermore, when the time Td1 elapses after the game is stopped, the viewing angle of the screen of the effect display 30 automatically returns to the wide viewing angle, so that a player who is looking for the desired pachinko machine while walking along the aisle Even if it does not move to the front of the pachinko machine 1, the display content of the effect display device 30 can be viewed from the lateral direction.

  The time when the game ball is not fired or the time when the game ball is not won can be measured as the time Td1 when the game is stopped. In this embodiment, the effect display 30 displays any variation / effect. The time when no pattern is displayed is measured as time Td1. For example, normally, when a game ball is continuously being fired, it is unlikely that the start opening will be won even for 1 minute. Therefore, the time Td1 is set to 1 minute, and the variation of the variation / direction pattern stops. If one minute has elapsed since then, it is considered that the game has been cancelled.

In addition, the effect indicator 30 may suggest that a big hit may occur in the near future by causing a specific image to appear in the background moving image. In the following, suggesting the possibility of a jackpot is called a jackpot notice. The jackpot notice includes a jackpot notice with a low expectation level and a high expectation notice with a high degree of expectation that the jackpot symbol is fixedly displayed.
The expectation here refers to the ratio of the appearance rate of the jackpot notice that leads to the jackpot to the total appearance rate that combines the appearance rate of the jackpot notice that leads to the jackpot and the appearance rate of the jackpot notice that leads to the loss. Is.

  The hold table and the random number storage table are provided for the first start port 21 and the second start port 22, respectively, but here, the hold table and the random number store table for the first start port 21 are representative. explain. 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 jackpot determination random number R3, the jackpot symbol random number R5 obtained from each random number counter, the probability state determination result and the hold number determination result are obtained. Stored in the corresponding storage order of the hold table 53a. 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 U1 is 1, each random number and each storage area of the storage order No. 2 in the holding table 53a are stored. The determination result is stored. That is, each random number and the determination result are stored in the storage order 1 to 4 in the winning order of the first start port 21. In the illustrated example, each random number and determination result stored in the storage order No. 1 is the oldest in terms of time, and each random number and determination result stored in the storage order No. 4 is the latest.

When the special symbol comes to the start of variation display, 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 / effects obtained by the MPU 71 for image and sound control from each random number counter. The pattern selection random number R10 is stored in the first storage area of the random number storage table 73a provided in the image / audio control RAM 73.
Note that the jackpot determination random number R3 and the jackpot symbol random number R5 are acquired when the game ball wins the first starting port 21, and are stored in No. 1 in the storage order of the holding table 53a. If the result of the jackpot determination performed at the start of display is a loss, the jackpot symbol random number R5 is not used to determine the variation / effect pattern.

In the example shown in FIG. 20A, the big hit determination random number 50 and the big hit symbol random number 85 are stored in the first storage order of the hold table 53a, and the reach selection random number 41, the second random number 85 are stored in the random number storage table 73a. A first variation group selection random number 162, a second variation group selection random number 91, and a variation / effect pattern selection random number 108 are stored. Further, the variation / effect pattern is determined to be the loss variation / effect pattern 1.
Therefore, the effect display device 30 displays the loss variation / effect pattern 1 in the next variation display.

  At this stage, since the variation display of the special symbol corresponding to the storage order No. 1 has not ended, the reach selection numbers 2 to 4 in the random number storage table 73a include the reach selection random number, the first variation group selection random number, The second variation group random number and the variation / effect pattern selection random number are not stored. When the display of the variation / effect pattern corresponding to the storage order No. 1 is completed, as shown in FIG. 23B, the storage order of each data stored in the hold table 53a is incremented by one, and random number storage is performed. In the storage order No. 1 in the table 73a, the newly acquired reach selection random number 109, first variation group selection random number 201, second variation group random number 65, and variation / effect pattern selection random number 103 are stored. The variation / effect pattern corresponding to the variation / effect pattern selection random number 103 is the jackpot variation / effect pattern 244.

  As shown in FIG. 22, the image data ROM 75 stores jackpot effect data 75a, jackpot game effect data 75b, customer waiting image data 75c, error notification data 75d, and the like. The big hit effect data 75a is image data for displaying on the effect display 30 an image for notifying the occurrence of a big hit when a big hit occurs. The jackpot game effect data 75b is image data for displaying on the effect display 30 an image for allowing the player to enjoy the jackpot game during the jackpot game period.

  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 special symbols are not variably displayed and game balls are 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. 23 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. 24 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. 23). When the main control MPU 51 determines that the power is turned on (S1: Yes), it executes a security check (S2) and stacks. 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. 24), 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. 24 will be described with reference to the drawings.
FIG. 25 is a flowchart showing the flow of the game start process executed by the main control MPU 51, and FIG. 26 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 image / audio control board 70, the effect control board 400, and the payout control board 60 (S101 in FIG. 25). 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 (S115 in FIG. 26). 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 (S115: Yes), the door / frame open state command is stored in the command transmission buffer (S116), and it is determined that the frame or door is not open. In this case (S115: No), the door / frame closed state command is stored in the command transmission buffer (S117).

  Subsequently, it is determined whether or not the 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 the prize ball cannot be paid out due to clogged balls (S118). 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 (S118: Yes), the prize ball abnormality command is stored in the command transmission buffer (S119), and if it is determined that the prize ball is not abnormal (S118: No). ), The winning ball normal command is stored (S120). 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. 24 will be described with reference to the drawings.
FIG. 27 is a flowchart showing the flow of the special symbol game process executed by the main control MPU 51, and FIGS. 28 and 29 are flowcharts 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 starting port 21 (S201 in FIG. 27). If it is determined that the game has won (S201: Yes), the special symbol hold number U1 is 4. It is determined whether it is less than the number (S202). Here, when it is determined that the special symbol hold number U1 is less than 4 (S202: Yes), 1 is added to the special symbol hold number U1 (S203), and the big hit determination random number R3 and the big hit symbol random number R5 Are stored in the hold table 53a of the main control work RAM 53 (S204).

  Subsequently, it is determined whether or not the first variable winning device 24 or the second variable winning device 25 (FIG. 9A) is in operation, that is, whether or not a 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. 9B) 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 S204 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 S204 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, when the big hit determination random number that is determined to be a big hit in S211 is a specific big hit determination random number, it is determined as a probable 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 the type of the big hit is determined (S214). This determination is performed using the jackpot type determination counter that generates the jackpot type determination random number R11 (FIG. 15) described above. The jackpot type determination counter generates a jackpot type determination random number R11 from 0 to 99. The same numerical value as the jackpot type determination random number in the predetermined range selected from the jackpot type determination random number R11 is associated with the jackpot type indicated by numbers 1 to 14 in FIG. 17, and the jackpot type determination random number obtained from the jackpot type determination counter Select the type of jackpot associated with the same number.

  For example, when the jackpot type determination random numbers 5 and 6 are associated with the 16R probability variable big hit indicated by number 1 in FIG. 17 and the jackpot type determination random number acquired from the jackpot type determination counter is 5, A 16R probability variable big hit (indicated by number 1 in FIG. 17) associated with the big hit type determining random number 5 is selected. Further, when the big hit type determination random numbers 78 and 79 are associated with the 15R probability variable big hit indicated by the number 14 in FIG. 17 and the big hit type determination random number acquired from the big hit type determination counter is 78, The 15R probability variation big hit (indicated by reference numeral 14 in FIG. 17) associated with the big hit type determining random number 78 is selected.

  If it is determined in S212 that it is not a probable big hit (S212: No), the normal big hit flag indicating that it is not a probable big hit, that is, a normal big hit is turned on (S215), and the type of big hit is determined. (S216). This determination is performed using the jackpot type determination counter that generates the jackpot type determination random number R11 (FIG. 15) described above. The jackpot type determination counter generates a jackpot type determination random number R11 from 0 to 99. The same numerical value as the jackpot type determination random number in a predetermined range selected from the jackpot type determination random number R11 is associated with the jackpot type indicated by numbers 15 and 16 in FIG. 17, and the jackpot type determination random number obtained from the jackpot type determination counter Select the type of jackpot associated with the same number.

  For example, the jackpot type determination random numbers 0 to 59 are associated with the 5R normal jackpot indicated by the number 15 in FIG. 17, and the jackpot type determination random numbers 60 to 99 and the 15R normal jackpot indicated by the number 16 in FIG. Assume that they are associated. When the big hit type determination random number acquired from the big hit type determination counter is 38, the 5R normal big hit (indicated by reference numeral 15 in FIG. 17) associated with the big hit type determination random number 38 is selected. If the jackpot type determination random number acquired from the jackpot type determination counter is 91, the 15R normal jackpot (indicated by reference numeral 16 in FIG. 17) associated with the jackpot type determination random number 91 is selected.

  Subsequently, the variation pattern of the special symbol is determined by lottery (S217 in FIG. 28), and the variation time set in the determined variation pattern of the special symbol is set (S218). Subsequently, each random number acquired in the previous S204, each determination result such as jackpot determination and probability variation jackpot determination, the data indicating the special symbol holding number U1 added in S203, and the effect instruction command are displayed in the MPU 71 for image and sound control. (S219). 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 (S220).

  Subsequently, measurement of the variation time set in S218 is started (S221). 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 (S222). Subsequently, it is determined whether or not a short-time game is in progress (S223), and if it is determined that a short-time game is in progress (S223: Yes), the number of changes in the special symbol when the short-time function is working (hereinafter, 1 is subtracted from C (referred to as the number of time reductions) (S224). Subsequently, it is determined whether or not the time reduction count C has become 0 (S225). If it is determined that the time reduction count C has become 0 (S225: Yes), the time reduction function is stopped (S226).

  If it is determined in S223 that the game is not a time-saving game (S223: No), it is determined whether or not the game is in the probability-changed game state (S227). It is determined whether or not there is a setting for a short time with respect to the probability variation jackpot whose state has changed to the probability variation gaming state (S228). If it is determined that there is a time reduction setting (S228: Yes), the time reduction number C1 corresponding to the set time reduction is set to the time reduction number C (S229). For example, if the type of jackpot is a probable big hit, and the jackpot game based on the probable big jackpot ends, the period until the number of changes in the special symbol reaches 70 times will change to a short-time game, The number of time reductions set to 70 for the probability variation big hit is set as the time reduction number C.

  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. 27 (S206: Yes), the variation time at which the measurement was started in S221 has elapsed. (S230 of FIG. 29), and when it is determined that it has elapsed (S230: Yes), the variation of the special symbol and the effect symbol is stopped (S231). Subsequently, it is determined whether or not the jackpot symbol has been confirmed and displayed (S232). If it is determined that the jackpot symbol has been displayed (S232: Yes), the jackpot game, that is, the special electric accessory game process is started (S233). . Subsequently, the probability changing function during the big hit game is stopped (S234), and the time reduction function is stopped (S235).

[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. 24 will be described with reference to the flowcharts of FIG. 30 and FIG.

  In this embodiment, the maximum number of winnings that can be won in the first big winning opening 24a per round is nine. The main control MPU 51 determines whether or not a big hit game is being played (S301), and if it is determined that the big hit game is not being set (S301: No), it determines the type of the big hit (S302). By this determination, the maximum number of rounds that can be executed in the big hit game, the variable winning device to be operated, the opening time of the big winning opening in each round, the presence / absence of a round without any play, and the like are analyzed. Subsequently, the round number Ra that can be executed set to the determined type of jackpot is set, and the current round number Rb is reset to 0 (S303). Subsequently, it is determined whether or not the round executed at this timing is a round with a game (S304).

  For example, when the type of jackpot determined in S302 is the 16R probability variable jackpot indicated by number 1 in FIG. 17, since all 16 rounds are rounds with a ball, it is determined that there are rounds with a ball. (S304: Yes). Also, if the type of jackpot determined in S302 is the 15R probability variation jackpot indicated by the number 12 in FIG. 17, the first round is very short and the opening time of the second big prize opening 25a is extremely short, and there is no winning. Therefore, it is determined that the round is not present (S304: No).

  Subsequently, if it is determined in S304 that there is a round with a payout (S304: Yes), the winning number Pa to the big winning opening is reset to 0, and the opening time Ta of the big winning opening is set (S305). . Subsequently, of the first variable winning device 24 and the second variable winning device, the variable winning device corresponding to the analysis result in S302 is operated to open the big winning opening (S306). Subsequently, measurement of the opening time Ta of the special winning opening set in S305 is started (S307), and 1 is added to the current round number Rb (S308). Subsequently, the current round number Rb is transmitted to the effect control MPU 71 (S313), and the round number Rb is displayed on the effect display 30.

  In S304, if it is determined that the round is not a game with a payout, that is, it is a round without a game (S304: No), the winning number Pa to the big prize opening is reset to 0, An opening time Tb is set (S309). Subsequently, of the first variable winning device 24 and the second variable winning device, the variable winning device corresponding to the analysis result in S302 is operated to open the large winning opening (S310). Subsequently, measurement of the opening time Tb of the special winning opening set in S309 is started (S311), and 1 is added to the current round number Rb (S312).

  Subsequently, in the next cycle, the special electric accessory game process is executed, and if it is determined that the big hit game is being played (S301: Yes), it is determined whether or not the game ball has won the big winning opening (FIG. 31). S314) When it is determined that a prize has been won (S314: Yes), 1 is added to the number Pa awarded to the big prize opening (S315). Subsequently, it is determined whether or not the number of winnings Pa to the big winning opening is 9 or more (S316), and when it is determined that the winning number Pa is not 9 or more (S316: No), It is determined whether or not the current round is a round with balls (S317). In other words, since the opening time of the big winning opening is different between the round with a ball and the round without a ball, it is determined whether or not the current round is a round with a ball.

  Here, when it is determined that the current round is a round with a play (S317: Yes). In S307, it is determined whether or not the opening time Ta of the big prize opening that has started the measurement has become 0 (S318). If it is determined that the opening time Ta of the big prize opening has become 0 (S318: Yes), it is large. The winning opening is closed (S320). In S317, when it is determined that the current round is not a round with a ball, that is, a round without a ball (S317: No), the opening time Tb of the big prize opening that started the measurement in S312 is It is determined whether it has become 0 (S319), and when it is determined that the opening time Tb of the big prize opening has become 0 (S319: Yes), the big prize opening is closed (S320).

  If it is determined in S316 that the number of winnings Pa to the big prize opening is 9 or more (S316: Yes), the big prize opening is closed (S320). Subsequently, it is determined whether or not the current round number Rb added in S308 has reached the maximum round number Ra set in S303 (S321), and it is determined that the current round number Rb has reached the maximum round number Ra. If it is (S321: Yes), the operation of the variable winning device is stopped and the big hit game is ended (S322). Subsequently, it is determined whether or not the probability variation jackpot flag is on (S323). If it is determined that the probability variation jackpot flag is on (S323: Yes), the gaming state is changed to the probability variation gaming state (S324). ). Subsequently, it is determined whether or not there is a time reduction setting (S325). If it is determined that there is a time reduction setting (S325: Yes), the time reduction function is started (S326). Subsequently, the big hit flag is turned off (S327). If it is determined in S321 that the current round number Rb has not reached the maximum round number Ra (S321: No), the process skips to S304 and executes the next round.

[Normal design game processing]
Next, the flow of the normal symbol game process executed by the main control MPU 51 in S400 of FIG. 24 will be described with reference to the drawings.
32 is a flowchart showing the flow of the normal symbol game process executed by the main control MPU 51, and FIG. 33 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. 32). 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 ordinary electric accessory 27 (FIG. 7) is in operation (S405). If it is determined that the ordinary electric accessory 27 (FIG. 7) is not in operation (S405: No), the normal symbol display device 33 (FIG. 9). 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 MPU 71 for image and sound control (S413 in FIG. 33). 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 the normal symbol game process is executed in the next cycle, if it is determined in S406 in FIG. 32 that the normal symbol is changing (S406: Yes), it is determined whether or not the change time has passed (FIG. 32). 33 (S417), if it is determined that the time has elapsed (S417: Yes), the fluctuation of the normal symbol is stopped (S418).

(S501: No), it is determined whether or not the winning flag is on by executing S410 (FIG. 32) 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).

  Then, when it is determined that the time Tc 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 Tc has become 0 (S505). Here, when it is determined that the time Tc has become 0 (S505: Yes), the operation of the ordinary electric accessory solenoid 27b is stopped and the open / close blade piece 27c is closed (S506). Subsequently, the hit flag is turned off (S507).

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

Next, the flow of the game stop time measurement process executed by the image / audio control MPU 71 in S700 of FIG. 35 will be described with reference to the flowchart of FIG.

  The image / audio control MPU 71 determines whether or not the game stop time indicating the time that the player has stopped the game is being measured (S701), and if it is determined that the player is not measuring (S701: No), It is determined whether or not the variation by the effect indicator 30 and the variation of the effect pattern are stopped (S702). Here, when it is determined that the variation / effect pattern variation is stopped (S702: Yes), measurement of the game stop time Td is started (S703).

  Subsequently, when the game stop time measurement process is executed in the next cycle, if it is determined that the game stop time is being measured (S701: Yes), the game stop time Td being measured is greater than or equal to a preset time Td1. It is determined whether or not (S704). If it is determined that the game stop time Td is equal to or greater than the time Td1 (S704: Yes), a game stop flag indicating that the game is stopped is turned on (S705). For example, as described above, when the time Td1 is set to 1 minute, the game stop flag is turned on when the game stop time Td becomes 1 minute or longer.

  In S704, when it is determined that the game stop time Td is not equal to or longer than the time Td1 (S704: No), it is determined whether or not the effect display 30 has started any change / change in the effect pattern ( S706). If it is determined that the variation / effect pattern variation has started (S706: Yes), the game suspension time Td being measured is reset to 0 (S707), and the game suspension flag is turned off (S708). That is, when the change / change of the effect pattern is started before the game stop time Td becomes equal to or longer than the time Td1, it is determined that the game is not stopped.

If it is determined that the variation display is not in progress (S801: No), the command reception processing is performed. In step S604, the analysis result stored in the image / audio control work RAM 73 is referred to, and it is determined whether or not the command received from the main control MPU 51 is an effect instruction command (S802).

  If it is determined that the command is an effect instruction command (S802: Yes), a reach selection random number, a first variation group selection random number, and a second variation group random number are acquired from each counter, and based on the acquired random numbers. A variation / effect pattern is determined (S803). Subsequently, the variation time of the variation / effect pattern determined in S803 is set (S804), the image processing LSI 76 is controlled, and the variation display of the variation / effect pattern is started on the effect display 30 (S805). Subsequently, measurement of the variation time set in S804 is started (S806).

  Then, when executing the image processing in the next cycle, it is determined whether or not the variation / effect pattern is in the variable display (S801). If it is determined that the variable display is in the display (S801: Yes), the measurement starts in S806. It is determined whether the changed time has elapsed (S807). If it is determined that the variation time has not elapsed (S807: No), it is determined whether it is time to perform the button effect (S808), and if it is determined that it is time to perform the button effect. (S808: Yes), button effect processing is executed (S809).

If it is determined in S808 that it is not the timing for performing the button effect (S808: No), it is determined whether it is the timing for performing the reach (S810), and if it is determined that it is the timing for performing the reach (S810). (S810: Yes), a reach effect is performed (S811).
