Abstract

PROBLEM TO BE SOLVED: To provide a Pachinko machine that improves efficiency in deleting information stored in a storage means such as a RAM.SOLUTION: If the time t when the Pachinko machine 1 is powered on is later than the closing time t1 of a Pachinko hall where the Pachinko machine 1 is set, and is earlier than the open time t2 of the Pachinko hall (S10:Yes), the result of probability-variable jackpot determination stored in a main control RAM 54 is deleted (S11). Accordingly, the result of affirmative determination remaining as a result of probability-variable jackpot determination can be automatically deleted simply by starting the power supply of each Pachinko machine 1, without operating a RAM clear switch in each Pachinko machine necessary for a conventional Pachinko machine.

Description

  The present invention relates to a pachinko machine configured to store and hold a CPU determination result such as whether it is a big hit or lost even when a power failure occurs during a game.

FIG. 25 is a front view of a conventional pachinko machine, and FIG. 26 is a back view of the pachinko machine shown in FIG.
As shown in FIG. 25, the conventional pachinko machine 600 includes a launch handle 601, a game board 602, a start port 603, an effect display 604, an upper plate 605, and a variable prize device 606. As shown in FIG. 26, on the back of the conventional pachinko machine 600, there are a control board 610 for controlling the effect display 604, a control board 611 for controlling the prize ball payout device, etc. A control board 612 that performs detection and the like and a RAM clear switch 613 are provided.

  When a game ball launched by the player operating the launch handle 601 wins the start port 603, a switch for detecting the game ball won in the start port 603 is turned on, and the microcomputer mounted on the control board 612 Judgment of big hit or loss (hereinafter referred to as big hit judgment) is performed. Then, the effect display unit 604 starts a variable display (also referred to as scroll display) of a plurality of symbols. For example, an array of symbols (hereinafter referred to as symbol rows) representing consecutive different numbers (for example, 0 to 9) is moved from the top of the screen to the bottom in the ascending order of the numbers in the three horizontal display areas on the screen. To display. Also, depending on the model, the symbol string is displayed so as to move from the right to the left of the screen.

  Then, when a predetermined time has elapsed after the effect display device 604 has started displaying the variation of the symbol sequence, the variation display of the symbol sequence is stopped in each display region, and the symbol corresponding to the determination result by the microcomputer described above is displayed in each display region. Will be displayed. For example, if the result of the big hit determination is a big hit, a big hit symbol consisting of the same number such as “777” is confirmed and displayed, and if the lottery result is a loss, a lost symbol such as “767” is confirmed and displayed. Is done. The fixed display is a display state in which the symbol indicating the result of the jackpot determination is fixed, and is a display state in which the symbol row does not change again. Hereinafter, the period from the start of the variable display of the symbol sequence to the final display of the jackpot symbol or the lost symbol is counted as one variation display.

  When the effect display 604 confirms and displays the big hit symbol, a big win occurs, and the variable winning device 606 opens the opening / closing member 607 and opens the big winning port 608. The large winning opening 608 has an opening area larger than that of an ordinary winning opening and has a large winning area, so that winning is facilitated. Then, a condition that a specified number (for example, 10) of game balls has won in the big prize opening 608 or a condition that the opening time of the big prize opening 608 has reached a prescribed time (eg, 30 seconds) is satisfied. Then, the opening / closing member 607 is closed and the special winning opening 608 is closed.

  Then, a round from the opening to closing of the special winning opening 608 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 winning 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. In addition, when a big hit occurs in a specific jackpot symbol, the gaming state after the big hit game based on the big hit is changed to a gaming state with a high probability of jackpot occurrence. Such a change in the probability of jackpot occurrence from a low probability to a high probability is called probability change.

  When the above-described microcomputer determines that the jackpot is a jackpot, it determines the type of jackpot symbol by lottery, determines whether the determined jackpot symbol type is a specific symbol, If there is, it is determined to be a promising big hit. In the future, the big hit that will cause a probability change is called the probability change big hit, and the big hit other than the probability change big hit is usually called a big hit. The determination of whether or not the probability variation big hit is called the probability variation big hit determination. Furthermore, a gaming state that has changed to probability change is referred to as a probability variation gaming state, and a gaming state other than the probability variation gaming state is referred to as a normal gaming state. Depending on the model, the probability variation gaming state may continue until the next jackpot occurs, and there may be a variation that continues until the number of times the symbol string is changed.

  By the way, the conventional pachinko machine 600 has been acquired by the player when the power is cut off because there is a possibility that the player suffers a disadvantage when a power failure occurs during the game and the power of the pachinko machine 600 is cut off. The data related to the profit is backed up to a RAM provided in the pachinko machine 600. For example, data indicating a normal jackpot determination result in jackpot determination, data indicating a promising jackpot, data indicating the number of winnings, and the like are backed up in the RAM. For example, even if a power failure occurs in the probability variation gaming state, if the power is restored, the continuation of the probability variation gaming state at the time of the power failure is reproduced.

  However, if the power supply is cut off when the pachinko hall is closed, the data backup function works in the same way as at the time of a power failure, so that the backed up data remains in the RAM and the next day's business is started. For this reason, for example, if a table in which data indicating the probability variation big hit remains in the RAM is selected, the probability variation gaming state is entered from the beginning. Therefore, the player who selects the table in which no advantageous data remains for such a player and Injustice arises between the two.

  Therefore, conventionally, when the pachinko hall is opened, the pachinko machine 600 is rotated around the left end, the RAM clear switch 613 (FIG. 26) disposed on the back of the pachinko machine 600 is operated, and the RAM is backed up. By eliminating the results of certain probable jackpot determinations, unfairness among players is prevented.

JP 2003-265721 A (paragraphs 31 to 32, FIGS. 4, 6, and 8)

  However, in the conventional pachinko machine 600, the pachinko machine has to be rotated one by one to operate the RAM clear switch 613, which requires a lot of trouble and increases the preparation time before opening the store. . That is, the conventional pachinko machine has a problem that the work efficiency for erasing the result of the probable big hit determination backed up in the RAM is poor.

  Therefore, the present invention has been made to solve the above-described problem, and a pachinko machine that can improve the work efficiency for erasing the result of the probable big hit determination stored in the storage means such as the RAM is provided. It aims to be realized.

Is not stored in the main control RAM 54.

[NMI processing]
Next, NMI (Non-Maskable Interrupt) processing of the main control CPU 52 and the payout control CPU 62 will be described with reference to the drawings.
FIG. 9 is a timing chart showing the relationship between the rise and fall of the power supply and the system reset and NMI processing timing of each substrate.

  In the following description, the sub board means each board other than the main control board 50 and the payout control board 60. Also, the voltage detected by the sub-board when the main power supply rises is the sub-board rise detection voltage, the voltage detected by the pay-out control board is the discharge control board rise detection voltage, and the voltage detected by the main control board is the main control board rise This is called the detection voltage. Also, the voltage detected by the main control board when the main power supply falls is the main control board fall detection voltage, the voltage detected by the payout control board is the discharge control board fall detection voltage, and the voltage detected by the sub board is the sub board This is called a fall detection voltage.

(Power up)
When the main power supply 77 (FIG. 6) is started, 5V power is supplied from the DC / DC converter 76c to each board, and a system reset signal (low level) is output and stabilized on all boards. Subsequently, the system reset signal of the sub-substrate is released (low level → high level) after a time Trs after the 5V power source reaches the sub-substrate increase detection voltage Vus, and the control of each sub-substrate is started.

  Then, 12V power is supplied to each board from the DC / DC converter 76b, and the system reset signal of the payout control board 60 is canceled after a time Trh after the 12V power supply reaches the payout control board rise detection voltage Vuh, and is used for payout control. The CPU 62 (FIG. 6) executes a security check. In this security check, it is checked whether there is any abnormality in the computer program stored in the payout control ROM 63. Subsequently, when the security check is completed, the payout control CPU 62 starts operation.

Then, the system reset signal of the main control board 50 is canceled after a time Trm after the 12V power source reaches the main control board rise detection voltage Vum, and the main control CPU 52 of the main control board 50 starts the operation after executing the security check. To do. Further, the main control CPU 52 transmits the result of the probability variation big hit determination stored in the main control RAM 54 to the hall computer 800. At this stage, the pachinko machine 1 is ready to play.
As described above, since control can be started in the order of the sub board, the payout control board 60, and the main control board 50, command reception from the main control board 50 is performed on all boards managed by the main control board 50. There is no risk of leakage.

(Power supply shutdown)
When the main power supply 77 is shut off due to power interruption at the end of pachinko hall operations, power failure, power supply abnormality, etc., and the 12V power supply reaches the main control board lowering detection voltage Vdm (for example, 10.3 V) (FIG. 9), The voltage drop appears at the NMI terminal of the main control MPU 51, an NMI signal is generated in the main control CPU 52, and access to the main control RAM 54 is prohibited. At the same time, power is supplied from the capacitor C2 (FIG. 8) as a backup power supply to the backup power supply terminal VBB of the main control MPU 51, and the stored contents of the main control RAM 54 are held.

In other words, the results of the jackpot determination executed by the main control CPU 52, the results of the jackpot symbol lottery, the results of the probable variation jackpot determination, the lottery symbol lottery result, the winning detection result, the gate passing detection result, and the normal symbol hit determination result For example, when the power is restored, storage of data necessary to resume the game from the state when the power is shut off is held.
When the time Tnmi has elapsed since the NMI signal was generated, a system reset signal is generated on the main control board 50 (high level → low level), and the main control board 50 is reset.

  Subsequently, when the 12V power source reaches the payout control board lowering detection voltage Vdh (FIG. 9), the voltage drop appears at the NMI terminal of the payout control MPU 61, and the payout control CPU 62 generates an NMI signal, thereby giving out the payout control RAM 64. Access to is prohibited. At the same time, power is supplied from the capacitor C1 (FIG. 8) as a backup power supply to the backup power supply terminal VBB of the payout control MPU 61, and the stored contents of the payout control RAM 64 are held. That is, the storage of data indicating the number of unpaid prize balls and the number of rented balls is held.

A system reset signal is generated on the payout control board 60 (high level → low level) when the time Tnmi elapses after the NMI signal is generated, and the payout control board 60 is reset.
Subsequently, when the 12V power supply reaches the sub-substrate down detection voltage Vds (FIG. 9), the sub-substrate is system-reset.

[Various tables]
Next, configurations of various tables stored in the image / audio control ROM 73 will be described with reference to the drawings. FIG. 10 is an explanatory diagram showing main storage contents of the image and sound control ROM 73 shown in FIG. FIG. 11 is an explanatory diagram showing the configuration of the variation pattern table.

  The image / sound control ROM 73 includes an effect symbol table 73a, a variation pattern table 73b, an effect content table 73c, an LED lighting pattern table 73d, a music table 73e, a jackpot effect image table 73f, a customer waiting image table 73g, and a button effect image table 73h. The data necessary for production is stored.

  The effect symbol table 73a is a table that the image / audio control CPU 72 refers to when the effect indicator 30 displays a lost symbol or a jackpot symbol. The variation pattern table 73b is a table that is referred to when the image / sound control CPU 72 determines the variation pattern of the effect symbol that the effect indicator 30 displays in a variable manner by lottery. In this embodiment, as shown in FIG. 11, the variation pattern table 73 b is configured by associating random numbers A to D for determining the variation pattern of the effect symbol by lottery.

  The random numbers A to D are count values counted by the counter, and each random number is equal to the range of count values counted by the counter. That is, the count value acquired from the counter by the image / audio control CPU 72 at a predetermined timing is a random number. The counter is, for example, a ring counter that counts a plurality of consecutive numerical values (for example, 0 to 239). The random numbers A to D are divided into groups 1 to n, respectively.

  A group 1 constituting the random number A is associated with a plurality of groups of random numbers B, and a group n constituting the random number A is associated with a group n of random numbers D. Each group constituting the random number B is associated with a plurality of groups of random numbers C. Each group constituting the random number C is associated with a plurality of groups of random numbers D. In addition, each random number constituting each group of random numbers D is associated with a different variation pattern.

  The CPU for image and sound control 72 acquires a random number (count value) one by one from each counter that generates the random number A to the random number D at the timing of determining the variation pattern of the effect symbol. Then, the group to which the random number acquired from the counter that generates the random number B belongs is selected from the groups to which the random number acquired from the counter that generates the random number A belongs. Subsequently, the group to which the random number acquired from the counter that generates the random number C belongs is selected from the groups associated with the selected random number B group. Subsequently, the group to which the random number acquired from the counter that generates the random number D belongs is selected from the groups associated with the selected random number C group. Subsequently, a variation pattern associated with the selected group of random numbers D is selected.

That is, the random number A, the random number B, the random number C, and the random number D are selected in this order, and the variation pattern finally associated with the random number D is selected. Since the probability that the same type of variation pattern is selected is reduced by configuring the plurality of random numbers and the variation pattern in association with each other as described above, it is devised so that the player does not get bored.
Among the variation patterns, a plurality of types of reach patterns are set as the reach pattern. For example, a normal reach pattern and a super reach pattern are set.

The normal reach pattern is a variation pattern having a high appearance probability among reach patterns that are variation patterns that develop into reach, and the super reach pattern is a variation pattern having a lower appearance probability than the normal reach pattern. The jackpot is generated through a reach pattern. In particular, when the super reach pattern appears, the jackpot occurrence probability is increased.
That is, when viewed from the player, the degree of expectation for occurrence of a big hit when a super reach pattern appears is the highest.

It should be noted that the group n of the random number D is associated with a normal variation pattern that does not develop to reach in the middle of the variation of the production symbol, and when the random number belonging to the group n of the random number A is selected, the normal variation pattern is selected. Is done.
Although not shown, the image / sound control ROM 73 stores a variation pattern table having a different configuration depending on the normal gaming state, the probability variation gaming state, the jackpot determination result, and the number of special symbols held, and varies depending on the gaming state. A variation pattern is selected.

  The effect content table 73c (FIG. 10) is a table that the image / audio control CPU 72 refers to when determining the effect content displayed by the effect display device 30 by lottery. The effect content is an effect that the player can change a part by pressing the effect button 9, for example, when the effect button 9 is pressed in the case where a video having a story is the effect content. It is a production that can change the development of the story.

  In addition, the contents of the effects may be displayed in combination with the variation pattern of the effects symbols or may be displayed alone without being combined. The effect content table 73c is stored in the image / sound control ROM 73 for each display time of the effect content. In addition, since the display time of the effect content is equal to the special symbol variation time, the effect content table 73c is provided at least as many times as the special symbol variation time.

The effect content lottery is performed using an effect content lottery counter that counts a plurality of consecutive different values. The effect content table 73c is configured by associating the count value of the effect content lottery counter with the effect content. Further, each effect content is set for each different display time, and a plurality of types of effect contents are set for one display time.
The image / audio control CPU 72 acquires one count value from the effect content lottery counter, and reads the effect content having the same display time as the change time of the change pattern instructed from the main control CPU 52 from the effect content table.

  The LED lighting pattern table 73d is a table that is referred to when the CPU 72 for image and sound control determines lighting patterns of various LEDs provided in the pachinko machine 1 by lottery. The LED lighting pattern lottery is performed using an LED lighting pattern lottery counter that counts a plurality of consecutive different numerical values.

  The LED lighting pattern table 73d is configured by associating the count value of the LED lighting pattern lottery counter with the LED lighting pattern. The CPU for image and sound control 72 acquires one count value from the LED lighting pattern lottery counter, reads the LED lighting pattern associated with the acquired count value from the LED lighting pattern table 73d, and follows the LED lighting pattern according to the lighting pattern. Is directed to the effect control CPU 402 to turn on.

  The music table 73e is a table that is referred to when the audio / video control CPU 72 determines the music output from the speakers 10 to 12 by lottery. Music lottery is performed using a music lottery counter that counts a plurality of consecutive different values.

  The music table 73e is configured by associating the count value of the music lottery counter with music. The image / audio control CPU 72 acquires one count value from the music lottery counter, reads the music associated with the acquired count value from the music table 73e, and instructs the audio output device 43 to output it. To do.

  The jackpot effect image table 73f is a table that is referred to when the image and sound control CPU 72 determines the effect image by lottery when a big hit occurs. The effect image lottery is performed using a jackpot effect image lottery counter that counts a plurality of consecutive different numerical values. The big hit effect image table 73f is configured by associating the count value of the big hit effect image lottery counter with the type of the big hit effect image. The image / audio control CPU 72 acquires one count value from the jackpot effect image lottery counter, reads the type of the jackpot effect image associated with the acquired count value from the jackpot effect image table 73f, and displays it. The effect display 30 is instructed as follows.

  The customer waiting image table 73g stores data for the image audio control CPU 72 to instruct the effect display 30 to display a customer waiting image when the pachinko machine 1 is not in a so-called customer waiting state. It is a table.

  The button effect image table 73h is referred to when the image / audio control CPU 72 determines the contents of the button effect image (effect image that can be selected by pressing the effect button 9) by lottery when the effect button 9 is turned on. It is a table. The button effect image lottery is performed using a button effect image lottery counter that counts a plurality of consecutive different values. The button effect image table 73h is configured by associating the count value of the button effect image lottery counter with the type of the button effect image. The image / audio control CPU 72 acquires one count value from the button effect image lottery counter when the effect button 9 is turned on, and sets the type of the button effect image associated with the acquired count value to the button effect image table. The effect display 30 is instructed to read from 73h and display it.

[Contents stored when a hold occurs]
Next, the contents stored in the image / sound control RAM 74 when the special symbol is suspended will be described with reference to the drawings.
FIG. 12A is an explanatory diagram showing the stored contents of the special symbol reservation table, and FIG. 12B is an explanatory diagram showing a state in which the storage order of the data stored in the special symbol reservation table is raised.

  In the following description, the confirmed symbol is an effect symbol that is confirmed and displayed by the effect indicator 30 and indicates any one of a normal big hit symbol, a probable big hit symbol, and a lost symbol. In addition, the special symbol reservation table is provided for each of the first start port 21 and the second start port 22. Here, the special symbol reservation table for the first start port 21 will be described as a representative. Further, 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.

  The special symbol holding table 74a stores data generated when the game ball wins the first starting port 21. The “holding order” in the figure indicates the order in which the holding occurred. The special symbol reservation table 74a stores a special symbol reservation number U1. The “determination result” is a result of the big hit determination and the probable change big hit determination performed by the main control CPU 52 when the game ball wins the first starting port 21. The “definite symbol” is a definite symbol determined by the main control CPU 52 when the game ball wins the first start port 21. The “variation pattern” is a variation pattern of the effect design determined by the image / audio control CPU 72.

The determination result and the determined symbol are transmitted from the main control CPU 52 to the image / sound control CPU 72 and stored in the special symbol hold table 74a by the image / sound control CPU 72.
The image / sound control CPU 72 also determines special symbol variation patterns and fixed symbols, music and LED lighting patterns, etc. by lottery and stores them in the special symbol hold table, but the description thereof is omitted here. A description will be given using the variation pattern and the fixed symbol as representatives.

FIG. 12A is an example showing the stored contents of the special symbol holding table 74a in a certain gaming state. In the third holding order (*), “probability variation big hit” is stored as a result of the probability variation big hit determination of the main control CPU 52, and “super reach pattern” is stored as a variation pattern. Further, the special symbol reservation number U1 stored in the special symbol reservation table 74a has reached the upper limit of four.
When the special symbol variation display is completed once, as shown in FIG. 12B, each data stored in the special symbol hold table 74a is moved up by one hold order.

[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 CPU)
First, the flow of main processing executed by the main control CPU 52 will be described with reference to the drawings. FIG. 14 is a main flowchart showing the flow of main processing executed by the main control CPU 52 shown in FIG. In the following description, a process step executed by the CPU is abbreviated as S.

  The main control CPU 52 executes initial settings such as a security check when the pachinko machine 1 is activated (S500). Next, the main control CPU 52 performs a RAM clear process (S501), a winning detection process (S502), a start port process (S503), a gate process (S504), a change start process (S505), and an ordinary electric accessory process (S506). ), Winning prize opening process (S507), game information transmission process (S508), and the like.

  In the winning detection process (S502), changes in output signals from the winning opening switches 17a to 20a, the start opening switches 21a and 27a, and the large winning opening switches 24c and 25c (FIG. 6) are detected to detect that a winning has occurred. To do. In the gate processing (S504), a change in the output signal from the gate switch 23a (FIG. 6) is detected, and it is detected that the game ball has passed through the gate 23, and a normal symbol hit determination is performed. In the ordinary electric accessory processing (S506), when the normal symbol hit determination in the gate processing (S504) is successful, the ordinary electric accessory solenoid 27b (FIG. 6) is operated to open and close the open / close blades of the ordinary electric accessory 27. The piece 27c (FIG. 3) is opened.

  In the big prize opening process (S507), the opening / closing control of the first big prize opening 24a when the normal big hit occurs and the opening / closing control of the second big prize opening 25a when the first or second positive variation big hit occurs. Execute. In the game information transmission process (S508), game information generated during the game, such as the number of occurrences of normal jackpots, the number of occurrences of probable big hits, the number of changes of special symbols, the total number of winning balls (number of balls played), etc. Send.

(RAM clear processing)
The flow of the RAM clear process executed by the main control CPU 52 in S501 (FIG. 14) will be described with reference to the flowchart shown in FIG.

  The main control CPU 52 determines whether or not the time t when the power of the pachinko machine 1 is started is later than the closing time t1 of the pachinko hall where the pachinko machine 1 is installed and earlier than the opening time t2. That is, it is determined whether or not t = t1 to t2 (S10). If the main control CPU 52 makes an affirmative determination, the result of the probability variation jackpot determination stored in the main control RAM 54 is erased (S11).

  Therefore, there is no need to operate the RAM clear switch for each pachinko machine as in the prior art, and by simply turning on the power of each pachinko machine 1, the result of the positive determination remaining as a result of the probable big hit determination is automatically deleted. Therefore, it is possible to improve the work efficiency of erasing the result of the probability variation jackpot determination.

(Start-up processing)
Next, the flow of the start port process (S503 in FIG. 14) executed by the main control CPU 52 will be described with reference to the drawings.
FIG. 16 is a main flowchart showing the flow of the start port process executed by the main control CPU 52 in S503 of FIG. 14, and FIG. 17 is a flowchart showing the continuation of the process shown in FIG. The main control CPU 52 executes the start port process when the first start port switch 21a or the second start port switch 27a is turned on, but here, the start port when the first start port switch 21a is turned on. The process will be described as a representative.

  The main control CPU 52 determines whether or not the first start port switch 21a (FIG. 6) is turned on, that is, whether or not the game ball has won the first start port 21 (FIG. 2) (S20). Here, if an affirmative determination is made (S20: Yes), the special symbol reservation number U1 stored in the main control RAM 54 is referred to (S21), and whether or not the special symbol reservation number U1 is less than the upper limit of four. Determine (S22). Here, if an affirmative determination is made (S22: Yes), one count value counted by the big hit lottery counter at this time is acquired (S23).

  Here, the big hit lottery counter is a counter that counts a plurality of consecutive different numerical values, and in this embodiment, is a ring counter that counts a total of 400 numerical values from 0 to 399. Subsequently, the main control CPU 52 determines whether or not the gaming state is a probability variation gaming state (S24). Here, when an affirmative determination is made (S24: Yes), the probability variation big hit jackpot value table is referred to (S25), and when a negative determination is made (S24: No), the normal big hit jackpot value table is referenced (S26). . The jackpot value table for probability variation jackpot is a table in which the jackpot value referred to in the probability variation gaming state is set, and the normal jackpot value table for normal jackpot is a table in which the jackpot value referenced in the normal gaming state is set. is there.

In the probability variation jackpot value table, more jackpot values are set than in the normal jackpot value table, and the probability that a jackpot will occur in the probability variation gaming state is high.
In this embodiment, a total of 10 jackpot values of 7, 53, 89, 113, 137, 157, 197, 257, 307, and 359 are set in the probability variation jackpot jackpot value table. Only the big hit value 7 is set in the value table.
In other words, the probability that a big hit will occur is 1/400 in normal time, and the probability change time is 10/400 = 1/40, and the probability that a big hit will occur in the probability changed gaming state is that of the normal gaming state. 10 times higher than when.

  Subsequently, the main control CPU 52 determines whether or not it is a big hit (S27). Here, if the big hit value of the same value as the count value acquired from the big hit lottery counter in the previous S23 is set in the probability variation big hit big hit value table or the normal big hit big hit value table, it is determined as big hit (S27: Yes) ) And a lottery drawing of the jackpot symbol is executed (S28). The jackpot symbol lottery is performed using a jackpot symbol lottery counter that counts a plurality of consecutive different values and a jackpot symbol table. The jackpot symbol table is configured by associating the count value of the jackpot symbol lottery counter with the jackpot symbol. The main control CPU 52 acquires one count value from the jackpot symbol lottery counter, and reads the jackpot symbol associated with the acquired count value from the jackpot symbol table.

  For example, the jackpot symbol lottery counter counts 0 to 9, and the jackpot symbol table is configured by associating the count values of 0 to 9 with the jackpot symbols 000 and 111 to 999. Then, when the count value acquired from the jackpot symbol lottery counter is 7, for example, the main control CPU 52 reads the jackpot symbol “777” associated with the count value 7 from the jackpot symbol table.

  If it is determined in S27 that the game is not a big hit, that is, it is lost (S27: No), a lottery of lottery symbols is executed (S29). Lost symbol lottery is performed using a loss symbol lottery counter that counts a plurality of consecutive different values and a loss symbol table. The lost symbol table is configured by associating the count value of the lost symbol lottery counter with the lost symbol. The main control CPU 52 acquires one count value from the lost symbol lottery counter, and reads the lost symbol associated with the acquired count value from the lost symbol table.

  Further, when determining the jackpot symbol by lottery, the main control CPU 52 determines whether or not the jackpot symbol is a normal jackpot according to the determined type of jackpot symbol (S34 in FIG. 17). For example, if the jackpot symbol determined by lottery is a jackpot symbol representing an even number such as 000 or 222, it is determined that the jackpot symbol is a normal jackpot. Here, if it is determined that it is a normal big hit (S34: Yes), a normal big hit flag indicating that it is determined that it is a normal big hit is turned on (S35).

  If it is determined that it is not a normal big hit (S34: No), it is determined whether or not it is a first positive variation big hit (S36). For example, when the jackpot symbol determined by lottery is 777, it is determined that the first probability variation jackpot. Here, if it is determined that it is the first probability variation jackpot (S36: Yes), the first probability variation jackpot flag indicating that it is determined that it is the first probability variation jackpot is turned on (S37).

  Further, when it is determined that it is not the first probability variation big hit (S36: No), it is judged whether or not it is the second probability variation big hit (S38). For example, if the jackpot symbol determined by the lottery is a jackpot symbol other than 777 and a jackpot symbol other than 777, it is determined that the jackpot symbol is the second probability variation jackpot. Here, if it is determined that it is the second probability variation big hit (S38: Yes), the second probability variation big hit flag indicating that it is determined that it is the second probability variation big hit is turned on (S39).

  Here, the normal jackpot is a jackpot for operating the first variable winning device 24, and is a jackpot for executing n3 rounds of opening and closing of the first jackpot 24a. Further, the first probability variation jackpot is a jackpot for operating the second variable winning device 25, and is a jackpot for executing n1 rounds of opening and closing of the second jackpot 25a. In addition, the second probability variation jackpot is a jackpot for operating the second variable winning device 25, and is a jackpot for executing n2 (n2 <n1) rounds in which the second prize winning opening 25a is opened and closed. For example, n1 = 16, n2 = 2, and n3 = 15.

In addition, the average value of the total number of prize balls to be paid out by winning at the first big winning opening 21 or the second big winning opening 22 during the big hit game is p1 for the first probability variable big hit and p3 for the normal big hit. When the second probability variation big hit is p2, p2 <p3 <p1. Further, if p2 / p1 = r, then 0.125 ≦ r <1.
In other words, the total number p2 of the number of prize balls that the player can obtain at the second probability variation jackpot is not less than 0.125 times (1/8) of the total number of prize balls p1 that can be earned at the first probability variation bonus. It is configured.

  Then, the main control CPU 52 adds 1 to the special symbol holding number U1 (S40), and shows data indicating the lottery result such as the special symbol holding number U1, the big hit determination result, the big hit symbol, the lost symbol, and the big hit type. It transmits to CPU72 for image sound control via the production control board 400 (S41).

(Variation start processing)
Next, the flow of the change start process (S505 in FIG. 14) executed by the main control CPU 52 will be described with reference to the flowchart shown in FIG.

  The main control CPU 52 determines whether or not the special symbol variation time is being measured (S50). If it is determined that the special symbol variation time is not being measured (S50: No), it refers to the special symbol hold number U1 (S51). ). Then, it is determined whether or not the special symbol reservation number U1 is 1 or more (S52). If it is determined that the number is 1 or more (S52: Yes), 1 is subtracted from the special symbol reservation number U1 ( S53), a variation start command for instructing the variation start of the special symbol and the effect symbol, and data indicating the current special symbol holding number U1 are transmitted to the image / audio control CPU 72 via the effect control board 400 (S54). Subsequently, measurement of the special symbol variation time (effect symbol variation time) is started (S55).

  Although not shown, the main control CPU 52 transmits the change start command to the image / sound control CPU 72 via the effect control board 400 in the probability variation gaming state, that is, the effect display unit 30 displays the effect symbol in a variable manner. The number of times is counted, and when the count value reaches a predetermined value, the first or second probability variation jackpot flag is turned off. For example, the first or second probability variation jackpot flag is turned off when the number of times of effect design variation display reaches 70. In other words, the period during which the player can enjoy the profit of certainty is the period until the number of times of display of the effect symbols changes reaches 70 times. Also, depending on the model of the pachinko machine, there is a case where there is no limit on the number of changes in the production symbol until the next jackpot occurs.

(Main processing executed by the image / audio control CPU)
Next, the main processing flow executed by the image / audio control CPU 72 (FIG. 7) will be described with reference to the flowchart of FIG.

  The image / audio control CPU 72 executes initial setting when the pachinko machine 1 is activated (S600). In this initial setting, a security check of the computer program is performed. Next, the image and sound control CPU 72 performs data reception processing (S601), variation pattern lottery processing (S602), sound effect pattern lottery processing (S603), LED lighting pattern lottery processing (S604), effect processing (S605), and movable. The accessory processing (S606) is executed.

(Data reception processing)
The flow of the data reception process (S601 in FIG. 19) executed by the image and sound control CPU 72 will be described with reference to the flowchart shown in FIG.

  The image / audio control CPU 72 determines whether or not data has been received from the main control CPU 52 via the effect control board 400 (S200). If it is determined that the data has been received (S200: Yes), the received data is analyzed. (S201). As a result of the analysis, it is determined whether the received data is a change start command or a lottery result such as jackpot determination and probability variation jackpot determination (S202, S203).

  If it is determined that the received data is not a change start command, that is, the received data is a lottery result (S202: No, S203: Yes), the received lottery result is stored in the image / audio control RAM 74 (S204). A variation pattern lottery process is executed (S205). The received lottery result is stored in the image / sound control RAM 74 in correspondence with the order in which the special symbol holding number U1 is generated. If it is determined in S202 that the command is a change start command, an effect process is executed (S220).

(Variation pattern lottery process)
Next, the flow of the variation pattern lottery process (S602 in FIG. 19) executed by the image / audio control CPU 72 will be described with reference to the flowchart shown in FIG.

  The CPU for image and sound control 72 refers to the special symbol reservation table 74a (FIG. 12) (S206), and refers to the variation pattern table 73b (FIG. 11) corresponding to the determination result and the number of special symbol reservations (S207). . Subsequently, as described for the variation pattern table 73b, the image / audio control CPU 72 selects a variation pattern using the random numbers A to D, and stores the selected variation pattern in the image / audio control RAM 74 (S208). ).

(Direction processing)
Next, the flow of the effect process (S605 in FIG. 19) executed by the image / audio control CPU 72 will be described with reference to the flowchart shown in FIG.

  The image / audio control CPU 72 determines whether or not the variation time of the effect symbol is being measured (S221), and if it is determined that the measurement symbol is not being measured (S221: No), the special symbol hold table 74a (FIG. 12). ), The variation pattern stored first in the generation order of the special symbol holding number U1 is read (S222), and the variation display of the representation symbol in accordance with the read variation pattern is started on the rendering display 30. (S223). Subsequently, the effect symbol variation time is set (S224), and the measurement of the effect symbol variation time is started (S225).

  Subsequently, the storage order of each data stored in the special symbol reservation table 74a is incremented by one (S226), and the special symbol reservation number U1 is updated by subtracting 1 from the special symbol reservation number U1 (S227). Then, when this effect process is executed in the next cycle, if it is determined in S221 that the variation time is being measured (S221: Yes), it is determined whether or not the measured time is up. (S228) If it is determined that the time is up (S228: Yes), the effect display 30 is caused to stop changing the effect symbol (S229), and the confirmed symbol associated with the change pattern read out in the previous S222. Is determined and displayed on the effect display 30 (S230).

(NMI interrupt processing)
Next, NMI interrupt processing executed by the main control CPU 52 and the payout control CPU 62 will be described with reference to the flowchart shown in FIG.

  When the power supply voltage supplied from the main power supply 77 (FIG. 6) to the main control board 50 is lowered to the main control board lowering detection voltage Vdm, the main control MPU 51 generates an NMI signal. When the NMI signal is generated, the main control CPU 52 sets access prohibition in the access register for the main control RAM 54 (S300). In other words, by prohibiting access to the main control RAM 54, the game such as the jackpot determination result, the probability variation jackpot determination result, the jackpot type, the number of special symbol fluctuations and the number of winnings stored in the main control RAM 54, etc. It is prevented that various data related to the profits of a person are rewritten.

  Further, when the power supply voltage supplied from the main power supply 77 (FIG. 6) to the payout control board 60 falls to the payout control board lowering detection voltage Vdh, the payout control MPU 61 generates an NMI signal. When the NMI signal is generated, the payout control CPU 62 sets access prohibition in the access register for the payout control RAM 64 (S300). In other words, by prohibiting access to the payout control RAM 64, various data relating to the player's profit such as the number of award balls and unpaid balls stored in the payout control RAM 64 are rewritten. To prevent.

  This NMI interrupt process is executed with the highest priority over other interrupt processes. In addition, when the voltage drop of the main power supply 77 is caused by a power failure, the pachinko machine 1 has a gaming state at the time of the power failure based on data stored in the main control RAM 54 and the payout control RAM 64 when the power is restored. Resume the game from

[Effect of the first embodiment]
(1) As described above, if the pachinko machine 1 according to the first embodiment is used, the result of the probable big hit determination stored in the main control RAM 54 is automatically obtained when the power of the pachinko machine 1 is turned on. Since it can be erased, the work efficiency for erasing the result of the probability variation jackpot determination can be improved.

(2) Only when the time t when the power of the pachinko machine 1 is turned on is later than the closing time t1 of the pachinko hall where the pachinko machine 1 is installed and earlier than the opening time t2. In order to erase the result of the probable change jackpot determination stored in the main control RAM 54, when the power is restored during a business interruption and the power is restored, the result of the probable change jackpot determination stored in the main control RAM 54 is incorrect. There is no risk of erasure.

(3) Further, it is possible to notify the main control RAM 54 that an affirmative determination result is stored as a result of the probable change jackpot determination, and to notify the notification LED 76j that the affirmative determination result has been deleted.
Therefore, it is possible to easily find the pachinko machine 1 in which the result of the positive determination is stored in the main control RAM 54 as the result of the probability variation jackpot determination, and easily recognize whether or not the result of the probability variation jackpot determination has been deleted. You can also.

Second Embodiment
A pachinko machine according to a second embodiment of the present invention will be described with reference to the drawings.
FIG. 24 is a flowchart showing the flow of the RAM clear process 2 executed by the main control CPU 52 of the pachinko machine according to this embodiment.

  When the power of the pachinko machine 1 is turned on, the main control CPU 52 has a current time t that is later than the closing time t1 of the pachinko hall where the pachinko machine 1 is installed and earlier than the opening time t2. Among these, it is determined whether or not a preset time t3 has been reached, that is, whether or not the current time t = t3 (S10). If the main control CPU 52 makes an affirmative determination, the result of the probability variation jackpot determination stored in the main control RAM 54 is erased (S11).

  Therefore, there is no need to operate the RAM clear switch for each pachinko machine as in the prior art, and by simply turning on the power of each pachinko machine 1, the result of the positive determination remaining as a result of the probable big hit determination is automatically deleted. Therefore, it is possible to improve the work efficiency of erasing the result of the probability variation jackpot determination.
