Further, the effect control board 200 is electrically connected to a lamp connection board 91 on which a plurality of LED drivers are mounted, and a lamp control signal (lamp data) for controlling the lamp connection board 91 is transmitted via a serial communication circuit. Send. In this example, the effect control board 200 and the lamp connection board 91 adopt clock-synchronized serial communication, and are transmitted by a signal line (clock line) different from the data line for lamp data transmission. The lamp control signal is transmitted bit by bit via the data line in synchronization with the clock signal. The lamp connection board 91 has a built-in LED driver that functions by receiving a lamp control signal for driving an LED transmitted from the effect control board 200, and switches on / off the switch in the circuit based on the lamp control signal. Therefore, the drive current is supplied or cut off to the effect lamp LP to control the effect lamp LP to be turned on or off.

Send. The motor driver 92 supplies a drive current to the stepping motor of each movable accessory 24 by switching the switch in the circuit on / off based on the drive control signal for driving the accessory transmitted from the effect control board 200. Alternatively, it is shut off to control the operation of each movable accessory 24. A parallel communication method is adopted for data transmission to the motor driver 92.

The image control board 300 includes a sub-sub CPU 301 that performs various arithmetic processes related to image production based on an image control command from the effect control board 200, a ROM 302 that stores an image control program, various data, and the like, and a work area that serves as a temporary storage area. It is equipped with an image control microcomputer (one-chip microcomputer) 310 configured to include a RAM 303 that functions as a buffer memory and an I / O port circuit 304 that inputs and outputs signals to and from peripheral boards and devices. , The sub-sub CPU 301 is configured to execute the main control related to the image production according to the control program stored in the ROM 302.

It is equipped with a sound source IC that generates acoustic data. The VDP is a so-called image processor, which reads image data stored in an image ROM in response to an instruction from a sub-sub CPU 301, processes the image data, and transmits a video signal (image data) generated by image processing to an effect display device. A high-speed VRAM used for developing and processing image data read from the image ROM is connected to this VDP. The sound source IC reads the acoustic data stored in the voice ROM in response to an instruction from the sub-sub CPU 301, and outputs the acoustic data generated by synthesizing the acoustic data to the speaker 11 via an amplifier (digital amplifier).

The payout control board 400 is mainly composed of a payout CPU 401, a ROM 402, and a RAM 403. The payout control board 400 is connected to the main control board 100 so as to be capable of bidirectional communication, and controls for driving the prize ball payout unit 34 to pay out the prize balls based on the payout control command from the main control board 100. Is executed, and the ball feeding mechanism 13 and the launching mechanism 14 are synchronously driven based on the amount of operation of the launching handle 12 to control the launching of the game ball.

Although not shown in detail, the power supply board 500 includes a normal power supply circuit for generating a normal power supply used in each control board based on the primary power supply supplied from the power supply equipment of the game island of the game facility. , A backup power supply circuit for generating a backup power supply and a power supply disconnection monitoring circuit for monitoring a power supply disconnection due to a voltage drop are provided for each electronic / electrical component such as a control board or a game device. Supply the required power. A power switch for activating the power circuit is connected to the power supply board 500, and assuming that the primary power is supplied from the power supply device of the game island, when the power supply switch is turned on, the power supply board A predetermined power supply is supplied to each control board or the like from the normal power supply circuit of 500. The power supply board 500 is configured to be able to detect that the power supply from the power supply device of the game island is cut off, and when the power supply disconnection is detected, the power supply disconnection signal (NMI signal) for notifying the fact is sent to the main control board 100. , Transmission to the effect control board 200 and the payout control board 400. The backup power supply circuit is charged when power is supplied from the power supply device of the game island to the pachinko game machine PM. Further, a RAM clear switch (not shown) for temporarily erasing the temporary storage contents of the RAM 103 of the main control board 100 and setting an initial value is connected to the power supply board 500 when the power of the pachinko gaming machine PM is turned on. ing. The RAM clear switch may be connected to, for example, the main control board 100 instead of the power supply board 500.

The external information terminal board 600 outputs an external information signal (outer end signal) to the outside of the game machine PM based on the game information signal from the main control board 100. The external information signals that the external information terminal plate 600 outputs as external information to an external device outside the machine include, for example, a jackpot signal, a continuous villa signal, a symbol confirmation signal, a prize ball signal (also referred to as a prize ball information signal), and a door. It includes a frame opening signal, a security signal (also referred to as a security information signal), a magnetic sensor abnormality signal, a disconnection short circuit power supply abnormality signal, an abnormality sensor detection (ball entry passage time abnormality, etc.) signal and the like. Further, the external device installed outside the game machine PM includes a data display, a hall computer, and the like. The data display is a device installed above the gaming machine PM and displaying data (game information) related to the operating state of the gaming machine PM based on an external information signal output from the gaming machine PM. The game information displayed on the data display is useful for the player to select a game machine. The hall computer aggregates the operating states of each game machine (this game machine PM is one of them) based on the external information signal output from each game machine installed in the hall in the game store, and each game. It is a device that manages the operating status of the machine. The hall computer may be electrically connected to the game machine PM via a data display, or may be electrically connected to the game machine PM without going through a data display.

Here, in the pachinko gaming machine PM of the present embodiment, as described above, the first special symbol lottery is performed when the gaming ball enters the first starting port 51. In addition, a normal symbol lottery is performed to determine whether or not to open the second starting port 52 when the game ball passes through the operating gate 53, and the game ball enters the second starting port 52. The second special symbol lottery will be held with the ball as an opportunity. When the opportunity for the lottery arrives, a random number value is acquired each time, and the success or failure of the lottery is determined based on the acquired random number value. Therefore, the generation and acquisition of the random number value used for the lottery will be described in detail below with reference to FIGS. 4 to 10.

FIG. 4 conceptually shows the components related to the acquisition of random numbers among the elements constituting the main control board 100 and their operations. As described above, the main control microcomputer 110 mounted on the main control board 100 is composed of a main CPU 101, a ROM 102, a RAM 103 (not shown), and an I / O port 104 (not shown). In the present embodiment, the first noise removing means F1 is further mounted on the main control board 100. Here, it is assumed that a Schmitt trigger inverter circuit is adopted as the first noise removing means F1. For example, Texas Instruments' 6-circuit Schmitt trigger inverter SN74HC14N has a short propagation delay time of about 11 ns and operates in a low active manner, which is less susceptible to noise, and is therefore suitable for use as the first noise removing means F1. A general-purpose input buffer (not shown) is provided on the input side of the Schmitt trigger inverter circuit. When the general-purpose input buffer is selected by the chip select signal, the detection signal from the start port switch or the like is input to the Schmitt trigger inverter circuit. To. When the first noise removing means F1 is a Schmitt trigger inverter circuit, the processing time for each lottery of the first noise removing means F1 is the propagation delay time (11ns) of the Schmitt trigger inverter circuit.

A random number generation circuit G, a latch register R, a second noise removing means F2, and a third noise removing means F3 are mounted on the main CPU 101. In the present embodiment, the second noise removing means F2 is implemented as a hardware circuit, and the third noise removing means F3 is implemented as software. However, both the second noise removing means F2 and the third noise removing means F3 may be implemented as a hardware circuit. Further, each noise removing means is not limited to the hardware circuit, and may be implemented as software. The ROM 102 has areas PCA1 and PCA2 for storing program codes that define the operation of the game machine, and the random number value acquisition program is stored in the first program code area PCA1. The random number value acquisition program stored in the ROM 102 is read by the main CPU 101, and the random number value acquisition process L is executed when the opportunity for lottery arrives. Each storage area of the ROM 102 will be described later.

Subsequently, the configuration and operation of the second noise removing means F2 and the latch register R will be described with reference to FIGS. 5 to 7. As described above, the main control board 100 communicates with other control boards by a parallel transmission method, and includes eight input terminals PI0 to PI7 as input ports. Although a plurality of input ports are provided in the main control microcomputer 110, in the present embodiment, an input port related to a lottery using a random number value will be described in particular. As shown in FIG. 5, in the present embodiment, the detection signal of the start port switch 511 output from the first noise removing means F1 (Schmitt trigger inverter circuit) is input to the input terminal PI0. Each input terminal (PI0 to PI7) is connected to the noise filter circuit F21, and the operation of the noise filter circuit F21 is set by the value of the filter control register F22. As shown in FIG. 6, the filter control register F22 can hold 8-bit data. The 3 bits from the 0th to 2nd bits are the setting values of the sampling width of the noise filter, the 3rd bit is the setting value of the active direction of the input terminal, and the 3 bits from the 4th to 6th bits are divided. It is a clock setting, and the 7th bit is used for setting (selecting) a sample reference clock. Since the sample reference clock changes depending on the set value of the 7th bit, the sampling width set in the 0th to 2nd bits is set by specifying a multiple of the sample reference clock. The value "00000001" of the filter control register illustrated in the figure means that the internal system clock is used as the sample reference clock, there is no frequency division, the input signal is low active, and the sampling width is set to four times the sample reference clock. ing.

FIG. 7 shows the operation of the noise filter circuit F21 when the value of the filter control register F22 is set to the value illustrated in FIG. The noise filter circuit F21 outputs a latch signal when an active signal is input for a time longer than the sampling width set by the filter control register F22. Here, the sampling width is set to four times the sample reference clock, so when the time for four reference clocks elapses after the input signal is switched from OFF (High) to ON (Low), the output signal is turned from OFF to ON. Switch to. For example, assuming that the internal system clock SCLK is 15.939 MHz, the sampling width is about 0.063 μs × 4 times = 0.252 μs. This sampling width corresponds to the noise removal processing time of the noise filter circuit F21. In the noise filter circuit F21, the noise-removed input signal is input to the parallel input port 104 and the selection register.

As shown in FIG. 8, the selection register can hold 8-bit data, and one selection register can set two random value registers. In the example of the figure, the 0th to 3rd bits are assigned to the setting of the random number register RL0_HV0 (see FIG. 5), and the 4th to 7th bits are assigned to the setting of the random number register RL0_HV1 (see FIG. 5). .. The 0th to 2nd bits and the 4th to 6th bits are bits for setting which input terminal signal is regarded as a latch signal and a random value is taken in. For example, in the example of the figure, since the 0th to 2nd bits are set to "000", the random number value register RL0_HV0 is an input signal from the PI0 terminal (starting port switch 511) (a signal that has passed through the noise filter circuit F21). Is regarded as a latch signal, and the output from the random number generation circuit G is taken in and held at the timing when the corresponding latch signal is input. Further, since the third bit is set to "0", a new value is not fetched from the random number generation circuit even if the next latch signal is input unless the latched value is read. That is, when a plurality of latch signals are continuously input, only the first latch signal is regarded as a valid signal, and the subsequent latch signals are invalidated. As a result, it is possible to prevent malfunction when chattering occurs.

Subsequently, the configuration and operation of the third noise removing means F3 will be described with reference to FIGS. 5, 9 and 10. The third noise removing means F3 inputs an input signal (for example, a detection signal of the start port switch 511) on the software by performing noise determination on the signal input to the I / O port (parallel input port) 104. This is a process for determining that the content has changed. As will be described later, when the timer interrupt process is activated, the value of the signal input to the parallel input port 104 is referred to by the operation control program at 4 ms intervals (S53 in FIG. 16). The referenced signal is selected by setting the input port register 105. As illustrated in FIG. 9, when the value of the bit (second bit) corresponding to the start port 1 of the input port register is set to "1", the value input from the PI2 terminal is the start port 1 switch. It is read as a detection signal (the detection signal of the start port switch of this embodiment is highly active). As shown in FIG. 10, the reading of the signal from the input port is performed five times for each interrupt process. In the present embodiment, since reading is performed at intervals of 5 μs, the processing time of the third noise removing means is approximately 25 μs.

If the values obtained in the five readings are all the same, the third noise removing means outputs the signal as a valid winning signal. If any of the values obtained in the five readings is different from the others, the signal is removed as noise (invalid signal). Specifically, if the five read values match, the matched value (1 or 0) is stored in the RAM as the level data of the current interrupt processing, and if they do not match, the level data of the previous interrupt processing is stored this time. It is retained as it is as the level data of interrupt processing of. Furthermore, by taking the exclusive OR of the current level data and the previous level data and taking the logical product of the result of the exclusive OR and the current level data, the entry of the game ball is detected at the starting port 1. Create rising data (winning signal) that means that.

Here, it will be described again with reference to FIG. As described above, the detection signals from the various switches are input to the main CPU 101, but in the present embodiment, the detection signals of the start port switch and the like are divided into two systems and input to the main CPU 101. One of the branched signals passes through the first noise removing means F1 and the second noise removing means F2, and if it is not determined to be noise there, it is supplied to the latch register as a valid latch signal. The latch register R latches the random number value output from the random number generation circuit G at the timing when the latch signal is supplied. The other of the branched signals passes through the third noise removing means F3, and if it is not determined to be noise there, it is supplied to the random number value acquisition program L as a valid winning signal. The random number value acquisition program L takes in the random number values held by the latch register at the timing when the winning signal is input, and performs various lottery using the random number values.

In the pachinko gaming machine PM of the present embodiment, as described above, the processing time of the first noise removing means is 11 ns, the processing time of the second noise removing means is 0.252 μs, and the processing time of the third noise removing means is 25 μs. As such, the components are selected or set. That is, the processing time of the third noise removing means is configured to be sufficiently longer than the total processing time of the first noise removing means and the second noise removing means. In such a configuration, the random number generated by the random number generation circuit is latched in the register at a timing sufficiently earlier than the timing at which the operation control program acquires the random number value used for the lottery, so that the used old random number value is used for the lottery process. It is possible to surely avoid the situation where it is used. Further, by providing the noise removing means (first noise removing means) independent of the main CPU 101, the number of noise removing means for the latch signal becomes a plurality of, and the accuracy of the noise removing process is improved. Further, both the second noise removing means and the third noise removing means carefully determine the noise by performing sampling a plurality of times. The number of samplings of the second noise removing means and the third noise removing means may be the same or different, but in either case, erroneous judgment is less likely to occur compared to noise judgment by one sampling, and the noise is disturbed at the wrong timing. It is possible to prevent the numerical value from being acquired.

The configurations of the first, second, and third noise removing means are not limited to the configuration of the present embodiment, and noise removing means having a configuration different from that of the present embodiment can be applied. The number of noise removing means is not limited to three, and other noise removing means may be added as long as the above conditions regarding the processing time can be satisfied. Further, in the present embodiment, the detection signal of the start port switch is directly input to the third noise removing means F3, but the signal output from the first noise removing means F1 or the output from the second noise removing means F2. The signal may be supplied to the third noise removing means F3.

<Basic operation of pachinko game machines>
In the pachinko gaming machine PM configured as described above, the outer frame 1 is fixedly installed on the game island of the game facility, and the front frame 2, the glass frame 5, etc. are closed and locked before being used for the game. The game is started by storing the game ball in the plate 8 and rotating the firing handle 12. When the launch handle 12 is rotated, the game balls stored in the upper ball plate 8 are sent out to the launch mechanism 14 one by one by the ball feed mechanism 13 arranged on the back side of the glass frame 5. It is launched into the game area PA by the launch mechanism 14. At this time, when the firing handle 12 is operated with less than a predetermined amount, the game ball does not reach the right side region PA2 and flows down the left side region PA1. In this left side region PA1, a left side flow path for allowing the game ball to flow down toward the first starting port 51 and the general winning openings 61 to 63 is formed. On the other hand, when the firing handle 12 is operated by a predetermined amount or more, the game ball reaches the right side region PA2 and flows down the right side region PA2. In the right side region PA2, a right side flow path for allowing the game ball to flow down toward the operating gate 53, the general winning opening 64, the second starting opening 52, and the large winning opening 54 is formed. The game balls flowing down the left side region PA1 or the right side region PA2 in this way have the first starting port 51, the second starting port 52, and the operating gate 53 according to the paths distributed in the left side region PA1 or the right side region PA1. , The ball can be entered in any of the large winning openings 54 and the general winning openings 61 to 64, but if the ball is not entered in any of the winning openings, the ball is flowed down to the out opening 29.

When a game ball flowing down the game area PA enters any of the first starting port 51, the second starting port 52, the large winning opening 54, and the general winning opening 61-63, a prize is given according to the type of the winning opening. The ball is paid out to the upper ball plate 8 or the lower ball plate 9 by the prize ball payout unit 34. The number of prize balls (referred to as "unit number of prize balls") to be paid out when one game ball enters each winning opening is "4" for the first starting port 51 and "4" for the second starting opening 52. "1 piece", "3 pieces" are set for the general winning openings 61 to 64, and "15 pieces" are set for the large winning opening 54. The number of unit prize balls in each winning opening is not limited to the example, and other unit prize balls may be applied. For example, as the number of unit prize balls, the first starting port 51 may be "1" instead of "4". Further, the second starting port 52 may be "3" instead of "1". Further, the general winning openings 61 to 64 may be "5" instead of "3". Further, the large winning opening may be "10" instead of "15".

When the game ball enters the first starting port 51 or the second starting port 52, a lottery random number value of the special symbol is acquired, and the random number value is temporarily stored as an operation holding ball of the special symbol up to a predetermined upper limit number. Then, when a predetermined start condition is satisfied, the winning / failing judgment, the symbol judgment, and the fluctuation pattern judgment of the special symbol are performed on the lottery random number value related to the earliest operation holding ball, and the mode according to the judgment result is performed. The special symbol is variably displayed on the first special symbol display device 71 or the second special symbol display device 72, and the decorative symbol is variably displayed on the effect display device 70. The variable display of the special symbol and the decorative symbol is synchronously stopped and displayed after the lapse of the variable time according to the selected variable pattern.

When the first special symbol or the second special symbol is confirmed and displayed in a stop mode indicating a big hit, the game shifts to a special game (big hit game) that is more advantageous to the player than the normal game. In each round game (unit game) of this big hit game, an opening / closing operation is performed in which the big winning opening 54 is changed to the open state only once or a plurality of times. When a predetermined number of game balls enter the large winning opening 54, or when the opening time of the large winning opening 54 reaches the opening time limit, the round game being executed ends. Here, the stop mode of the decorative symbol indicating the big hit is, for example, an embodiment in which three types of symbols match. When the special symbol and the decorative symbol are confirmed and displayed in the stop mode indicating the jackpot, a plurality of round games (unit games) are executed as the jackpot game.

If a predetermined jackpot is won, the probability variation function of the special symbol may be activated from the end of the jackpot game until the number of fluctuations of the special symbol reaches the predetermined final number of times. When the probability fluctuation function of the special symbol is activated, the jackpot probability of the special symbol lottery shifts from the normal low probability state to the high probability state, so that a new jackpot (big hit game) will occur relatively early. Become. The probability fluctuation function of the special symbol may be continued until the next big hit occurs. Further, as the predetermined final number of times, "10000 times" may be set, which substantially corresponds to the number of variable display times until the next big hit occurs.

In addition, after the jackpot game is completed, it may be attached to or independently of the probability fluctuation function of the special symbol.
The variable time reduction function for special symbols may be activated. When the special symbol variation time shortening function is activated, the average variation time of the special symbol and the decorative symbol tends to be shorter than usual, and the number of special symbol lottery per unit time is improved (big hit per unit time). Ease of acquisition can be increased).

Further, after the jackpot game is completed, the electric chew support function (also simply referred to as "electric support") may be activated in association with or independently of the function of shortening the fluctuation time of the special symbol. The electric chew support function enhances the ease of entering the second starting port 52 by operating the probability fluctuation function of the normal symbol, the fluctuation time shortening function of the normal symbol, and the opening extension function of the normal electric accessory 522. It is a state (also referred to as "electric support state" or "easy ball entry state"). When the probability fluctuation function of the normal symbol is activated, the winning probability of the normal symbol becomes higher than that in the normal state. When the function for shortening the fluctuation time of the normal symbol is activated, the fluctuation time of the normal symbol is shortened. When the opening extension function of the ordinary electric accessory 522 is activated, the opening time of the ordinary electric accessory 522 is extended from the normal state. In this easy-to-enter state, the number of fluctuations of the normal symbol per fixed time is more likely to increase than usual, and the ease of entering the second starting port 52 is also increased, so that the second starting port 52 is reached. It also increases the possibility that the number of balls entered will increase. Therefore, by operating the electric chew support function, the chances of obtaining a prize ball by entering the second starting port 52 during that period increase, and as a result, it is possible to continue the game with almost no reduction in the number of balls held. Become. That is, the "base", which is the ratio of the number of prize balls to the number of launched balls of the game ball, becomes high. Hereinafter, the state in which the electric chew support function is operating is also referred to as a “high base state”, and the state in which the electric chew support function is not operating is also referred to as a “low base state”.

<Main functional configurations of pachinko machines>
Next, various functions of the pachinko gaming machine PM (mainly the main control board 100) will be described with reference to FIG. 11. Note that FIG. 11 is a functional block diagram of the game machine PM (mainly the main control board 100).

As shown in FIG. 11, the main control board 100 includes a ball entry determination means 111, a game lottery random number generation means 120, a hold control means 130, a preliminary determination means 135, a special symbol lottery processing means 140, and a normal symbol lottery processing means 145. Includes special game control means 150, symbol display control means 155, electric accessory control means 160, game state control means 165, error monitoring control means 170, main information storage means 180, and command transmission / reception means 190. Each of the above-mentioned means on the main control board 100 is composed of hardware such as a main CPU 101, ROM 102, RAM 103, and electronic circuits provided on the main control board 100, and software such as a control program stored in the ROM 102 and the like. It is a functional representation of something.

The ball entry determination means 111 is based on detection signals from the first start port switch 511, the second start port switch 521, the operation gate switch 531 and the large winning opening switch 541, the general winning opening switch 611, 641, and the like, and each winning opening. Judge the entry of the game ball into. When the ball entry determination means 111 detects the entry of a game ball by the first start port switch 511, the ball entry determination means 111 generates an effect control command (referred to as “first start port winning command”) to that effect, and the first 2 When the entry of the game ball is detected by the start port switch 521, an effect control command (referred to as "the second start port winning command") indicating that fact is generated, and the operation gate switch 531 of the game ball When the passage is detected, an effect control command (referred to as "operation gate winning command") indicating that fact is generated, and when the large winning opening switch 541 detects the entry of the game ball, it indicates that fact. When a production control command (referred to as a "large winning opening winning command") is generated and a game ball entry is detected by the left general winning opening switch 611, a directing control command indicating that fact ("left general winning opening") (Referred to as "winning command") is generated, and when the right general winning opening switch 611 detects the entry of a game ball, an effect control command (referred to as "right general winning opening winning command") is generated to that effect. Then, this is temporarily stored in the command storage area of the main information storage means 180.

The game lottery random number generating means 120 is used for a winning / losing lottery of a special symbol by taking in a built-in random number generated by the random number generation circuit of the main control microcomputer 110 by software and adding a soft random number per special symbol described later to the built-in random number. Generate a random number per special symbol. Further, the game lottery random number generation means 120 includes a random number counter for generating various software random numbers by the program processing of the main CPU 101. These random number counters play a role as random number generation means for generating random numbers by software. As this software random number, the initial value for a new update after one cycle of the special symbol soft random number added to the above-mentioned built-in random number for the hit random number generation and the special symbol soft random number update is completed. Soft initial value random number per special symbol for determining, special symbol stop symbol random number used to determine the hit symbol (combination of symbols that activates the condition device) as the stop symbol of the special symbol, special symbol stop symbol random number Special symbol stop symbol initial value random number for determining the initial value for new update after one cycle of update is completed, special symbol variation pattern random number for use in selecting the variation pattern of the special symbol, Random numbers per ordinary symbol to be used for winning / failing lottery of ordinary symbols, initial value random numbers per ordinary symbol to determine the initial value for new updates after one cycle of random numbers per ordinary symbol is completed, Ordinary symbol variation pattern Random numbers for use in selecting the variation pattern of the ordinary symbol are included. These software random numbers are updated once each time timer interrupt processing occurs (increment, decrement, addition of prime numbers, etc.), and the initial value random numbers are not executed while timer interrupt processing is being executed (increment, decrement, addition of prime numbers, etc.). (During loop processing) is also updated using the remaining time of the interrupt cycle.

The hold control means 130 includes a special symbol hold control means 131 and a normal symbol hold control means 132.

The special symbol holding control means 131 is a lottery random number value related to the special symbol game, which is a random number value per special symbol, per special symbol, triggered by the entry of the game ball into the first starting port 51 or the second starting port 52. The symbol random value and the special symbol fluctuation pattern random value are acquired, and the random value is managed as the operation pending ball information of the first special symbol or the second special symbol. The special symbol holding control means 131 is a main information storage means in which the operation holding ball information of the first special symbol or the second special symbol is combined with the entry order of the holding balls up to a predetermined upper limit number (4 pieces). Temporarily stored in the first special symbol holding storage area or the second special symbol holding storage area of 180.

In the first special symbol hold storage area and the second special symbol hold storage area, the hold 1 storage area (first hold storage area) and the hold 2 storage area (2) are in the order of entry into the starting ports 51 and 52. A third reserved storage area), a reserved 3 storage area (third reserved storage area), and a reserved 4 storage area (fourth reserved storage area) are provided. Each hold storage area can store a random number per special symbol, a random number per special symbol, and a random number of special symbol variation patterns as a set of operation hold ball information. The operation hold ball information is stored in the order of hold 1 storage area, hold 2 storage area, hold 3 storage area, hold 4 storage area, while hold 1 storage area, hold 2 storage area, hold 3 storage area, hold 4 storage. It is digested in the order of areas (first-in, first-out principle). When the reserved ball information in the reserved 1 storage area is digested, the reserved ball information stored in the reserved 2 storage area, the reserved 3 storage area, and the reserved 4 storage area is shifted to the lower numbered storage area, respectively. Hold 4 Clear the contents of the storage area to zero.

Further, the special symbol holding control means 131 has a first special symbol holding ball number counter for counting the number of operating holding balls of the first special symbol, and a second special symbol holding ball number counter for counting the number of operating holding balls of the second special symbol. It has a special symbol hold ball number counter. The special symbol holding control means 131 adds 1 to the corresponding counter every time one of the special symbol's operation-holding balls is acquired as an update process of the number of operation-holding balls of the special symbol, and one operation-holding ball is digested. The corresponding counter is subtracted by 1 for each.

Further, when the special symbol hold control means 131 updates (adds or subtracts) the number of operation hold balls of the first special symbol or the second special symbol, the effect control command (“symbol memory”) including the update information of the hold ball number A number command) is generated and temporarily stored in the command storage area of the main information storage means 180. This one command includes information on both the number of balls on hold for operation of the first special symbol and the number of balls on hold for operation of the second special symbol. As a general rule, the operation-holding balls of each special symbol are digested in the order in which they are entered, but the so-called priority digestion is performed in which the variation display of the second special symbol is preferentially executed over the first special symbol. It may be adopted. That is, while the operation-holding ball related to the second special symbol game exists, the operation-holding ball related to the second special symbol game is preferentially digested regardless of the existence of the operation-holding ball related to the first special symbol game. It may be configured as follows. Under priority digestion, if the operation-holding ball of the second special symbol is present, the digestion of the operation-holding ball of the first special symbol is suspended even if the operation-holding ball of the first special symbol is present. It will be.

The normal symbol holding control means 132 is a lottery random number value related to the normal symbol game, triggered by the entry of the game ball into the operating gate 53, which is a random value per normal symbol, a symbol random value per normal symbol, and a normal symbol variation pattern. A random number value is acquired, and the random number value is managed as operation holding ball information of a normal symbol. The normal symbol hold control means 132 stores the normal symbol operation hold ball information up to a predetermined upper limit number (4 pieces) in the normal symbol hold storage area of the main information storage means 180 in the form of being combined with the ball entry order of the hold balls. Temporarily memorize. Further, the normal symbol holding control means 132 has a normal symbol holding ball number counter for counting the number of operating holding balls of the normal symbol. The normal symbol hold control means 132 adds 1 to the corresponding counter every time one of the normal symbol hold balls is acquired as the process of updating the number of hold balls of the normal symbol, and one action hold ball is consumed. The corresponding counter is subtracted by 1 for each.

When the pre-determination means 135 acquires an operation-holding ball with a special symbol at a predetermined pre-determination timing, the pre-determination means 135 executes a pre-determination for pre-reading notice for the operation-holding ball. As an example of the above-mentioned pre-judgment timing, when (1) waiting for a hit and when the operation holding ball of the first special symbol is acquired while the electric chew support function is not operating, (2) waiting for a hit and When the operation holding ball of the second special symbol is acquired while the electric chew support function is operating, or (3) when the operation holding ball of the second special symbol is acquired during the big hit, one of the conditions is satisfied. It's time. The above-mentioned pre-judgment timing is an example, and the pre-judgment timing is changed according to the specifications of the game machine (for example, it has a start port related to the second special symbol that does not have an ordinary electric accessory, and eight pieces are normally reserved. For models that can store, the above (1) can be applied not only to the first special symbol but also to the second special symbol, etc.), or even if a specification that makes a preliminary judgment at any time without setting a pre-judgment timing is adopted. Good. Further, in each game state, only the operation-holding ball of the special symbol that is the main player of the game may be the target of the preliminary determination. For example, in the normal game state, only the operation-holding ball of the first special symbol is the target of the preliminary determination. Therefore, in the time-saving game state, the latent probability change game state, and the probability change game state, it is preferable that only the operation holding ball of the second special symbol is the target of the preliminary determination. Specifically, the pre-determination means 135 reads the random number value corresponding to the operation hold ball acquired this time from the first special symbol hold storage area or the second special symbol hold storage area of the main information storage means 180, and determines whether or not the result is correct. Pre-judgment (pre-judgment of hit / fail), pre-judgment of symbol (pre-decision of symbol), and pre-judgment of fluctuation pattern (pre-judgment of fluctuation pattern) are sequentially executed. Although the pre-judgment table used in each pre-judgment is not shown, the area corresponding to the total number of random numbers in each of the hit / fail pre-judgment table, the symbol pre-judgment table, and the variation pattern pre-judgment table is divided into a plurality of areas. A lottery ID (a number indicating the result of the pre-judgment (also referred to as a "pre-judgment number")) is assigned to each of these areas (determination number). Therefore, the result of this preliminary determination is based on the result of the main lottery by the special symbol lottery processing means 140 described later (result of winning / failing determination, result of symbol determination, result of variation pattern determination). The winning / failing pre-determination table, the symbol pre-determining table, and the like may be the same as the winning / failing lottery table and the symbol lottery table used for the lottery when the fluctuation is actually started. Here, the fluctuation pattern pre-determination table may change the game status at the start of fluctuation (whether or not there is a probability change, whether or not there is a time reduction, whether or not it is during a limited frequency period that refers to a special table, the number of reserved balls, etc.). Therefore, as described above, it is desirable to determine which of the plurality of regions is included. Further, as a modification, it is configured to predetermine a random value such as a register on the main CPU 101 that is temporarily stored before being stored in the first special symbol hold storage area or the second special symbol hold storage area. You may. Then, the pre-determination means 135 sequentially generates an effect control command (referred to as a "pre-determination command") including information on the result of the pre-determination (pre-determination number), and stores this in the command storage area of the main information storage means 180. Store in.

The special symbol lottery processing means 140 includes a special symbol winning / failing determination means 141, a special symbol stop symbol determining means 412, and a special symbol variation pattern determining means 143. When the change start condition of the first special symbol or the second special symbol is satisfied, the special symbol lottery processing means 140 is set in the earliest storage area (hold 1 storage area) of the special symbol hold storage area in the main information storage means 180. The stored random value per special symbol, random value per special symbol, and special symbol variation pattern random value are read out and used as the special symbol hit / fail determination area, special symbol symbol determination area, and special symbol variation pattern of the main information storage means 180. Store each in the judgment area. Here, "the condition for starting the fluctuation of the first special symbol is satisfied" means that (A1) the jackpot is not in progress, (A2) the first special symbol and the second special symbol are waiting for fluctuation, and (A3). ) When all the conditions that the operation holding ball of the first special symbol exists is satisfied. In addition, "the condition for starting the fluctuation of the second special symbol is satisfied" means that (B1) the jackpot is not in progress, (B2) the first special symbol and the second special symbol are waiting for fluctuation, and (B3). It is when all the conditions that the operation holding ball of the second special symbol exists is satisfied. When the fluctuation start condition of the first special symbol and the fluctuation start condition of the second special symbol are satisfied at the same time, the fluctuation start condition of the second special symbol is preferentially processed under the above-mentioned priority digestion. To do.

The special symbol winning / failing determination means 141 reads a random number value per special symbol from the special symbol winning / failing determination area of the main information storage means 180, executes a winning / failing determination, and determines whether the determination result corresponds to a big hit or a miss. decide. The result of this pass / fail determination is temporarily stored in the special symbol determination flag of the main information storage means 180 (for example, jackpot data "55H", missed data "00H"), and after being used in the subsequent processing, the special symbol changes. Cleared when stopped. The special symbol winning / failing determination means 141 holds a special symbol winning / failing lottery table that is referred to at the time of this winning / failing determination.

Here, FIG. 12 is a diagram schematically showing a special symbol winning / failing lottery table. FIG. 12A is referred to in a gaming state (low probability state) in which the probability variation function of the special symbol is not activated, and FIG. 12B is a gaming state (high probability) in which the probability variation function of the special symbol is activated. State). In the special symbol winning / failing lottery table, the random number range of the random number value per special symbol and the result of the winning / failing determination of the special symbol (big hit, miss) are associated with each other. As shown in FIG. 12, in the winning / failing determination of the special symbol, the random value per special symbol corresponds to the range of "0 to 204" in the gaming state (low probability state) in which the probability fluctuation function of the special symbol is not activated. In the game state (high probability state) in which the probability fluctuation function of the special symbol is activated, a big hit is obtained when the random number value per special symbol falls in the range of "0 to 1506". That is, when the probability fluctuation function of the special symbol is activated, the winning probability of the big hit changes from the low probability "1 / 319.69" to the high probability "1 / 43.49". In this way, the jackpot winning probability changes according to the game state, but the jackpot winning probability is set equally between the winning / failing determination of the first special symbol and the winning / failing determination of the second special symbol. In the present embodiment, "small hit" is not set as the result of the hit / fail judgment of the special symbol, but "small hit" may be set as the result of the hit / miss judgment of the special symbol. The winning probability of a small hit is set to the same winning probability regardless of the gaming state (low probability state, high probability state).

The special symbol stop symbol determination means 142 determines the stop symbol of the first special symbol or the second special symbol based on the result of the winning / failing lottery of the first special symbol or the second special symbol. As shown in FIG. 13, the special symbol stop symbol determining means 142 uses the first special symbol jackpot symbol table and the second special symbol jack symbol table and the second, which are referred to when determining the jackpot symbol (big hit type) of the first special symbol and the second special symbol. It has a special symbol jackpot symbol table. Here, "specific jackpot" means a jackpot (probability variable jackpot) that triggers the activation of the probability fluctuation function of the special symbol after the jackpot game ends, and "normal jackpot" means the probability of the special symbol after the jackpot game ends. It means a big hit (non-probable variable big hit) that does not trigger the activation of the variable function.

The special symbol variation pattern determining means 143 determines the variation pattern of the special symbol based on the special symbol variation pattern random value. Here, the special symbol variation pattern determining means 143 holds a plurality of types of variation pattern tables that are referred to when selecting a variation pattern of the special symbol. The special symbol variation pattern determining means 143 selects any variation pattern table from a plurality of types of variation pattern tables based on the current variation pattern selection state. The relationship between the fluctuation pattern selection state and the fluctuation pattern table will be described later. A plurality of types of fluctuation patterns are defined in each fluctuation pattern table. In each figure, "selectivity" is shown for convenience of explanation, but in reality, a judgment value (range of random values) for determining the fluctuation pattern is set according to the special symbol fluctuation pattern random value. The fluctuation pattern is determined based on which determination value the fluctuation pattern random value belongs to. It is premised that the various fluctuation patterns are associated with the fluctuation time for each fluctuation pattern as the end condition of the fluctuation display of the special symbol, and that the fluctuation display of the decorative symbol is also executed at the fluctuation time.

The normal symbol lottery processing means 145 includes a normal symbol winning / failing determination means 146, a normal symbol stop symbol determination means 147, and a normal symbol variation pattern determination means 148. When the normal symbol fluctuation start condition is satisfied, the normal symbol lottery processing means 145 reads out the normal symbol per normal symbol value and the normal symbol fluctuation pattern random value stored in the earliest storage area in the normal symbol hold storage area. It is stored in the normal symbol hit / miss determination area and the normal symbol variation pattern determination area of the main information storage means 180, respectively. Here, the "conditions for starting the fluctuation of the normal symbol" are (1) waiting for the fluctuation of the normal symbol, and (2) the existence of the operation holding ball of the normal symbol. When all of these conditions are satisfied, it is determined that the normal symbol is in a state in which the fluctuation can be started (a state in which the fluctuation start condition is satisfied).

The normal symbol hit / fail determination means 146 reads a random value per normal symbol from the normal symbol hit / fail determination area of the main information storage means 180, executes a hit / fail judgment of the normal symbol, and the determination result is either "hit" or "miss". Determine if this is the case. The result of the hit / fail determination of the normal symbol is temporarily stored in the normal symbol determination flag of the main information storage means 180, used in the subsequent processing, and then cleared when the fluctuation of the normal symbol is stopped. The ordinary symbol winning / failing determination means 146 holds a non-illustrated ordinary symbol winning / failing lottery table that is referred to when determining whether or not the ordinary symbol is correct. The hit probability of the normal symbol is set to "1/3001" when the electric chew support function (probability fluctuation function of the normal symbol) is not activated, and the electric chew support function (probability fluctuation function of the normal symbol) is activated. If it is, it is set to "2999/3001".

The normal symbol stop symbol determination means 147 refers to a normal symbol stop symbol table (not shown), and if the result of the hit / fail determination of the normal symbol is a hit, the predetermined hit symbol (the trigger for the normal electric accessory 522 to operate). On the other hand, if the result of the hit / fail judgment of the normal symbol is incorrect, a predetermined missing symbol (a stop symbol that does not trigger the operation of the ordinary electric accessory 522) is selected.

The ordinary symbol variation pattern determining means 148 reads the ordinary symbol variation pattern random value from the ordinary symbol variation pattern determination area of the main information storage means 180, and also refers to the ordinary symbol variation pattern table (not shown) to refer to the ordinary symbol variation pattern table. Determine (variation time). The fluctuation time of the normal symbol is set to "0.6 seconds" when the electric chew support function (function to shorten the fluctuation time of the normal symbol) is not activated, and the electric chew support function (function to shorten the fluctuation time of the normal symbol). Is set to "0.2 seconds" when is operating. Regardless of which normal symbol variation pattern is selected, the fixed stop time (fixed display time) of the normal symbol is set to "0.1 seconds". The fixed stop time (fixed display time) of the normal symbol is the time when the normal symbol is definitively stopped and displayed (the time when the completely stopped state is maintained). In the control of the normal symbol, in order to reduce the processing load of the main control board 100, when the electric chew support function is not operating, the hit probability of the hit / fail judgment of the normal symbol is set to "0", and the normal symbol is controlled. It is also conceivable to adopt a specification in which the fluctuation time is a single one.

Further, the ordinary symbol lottery processing means 145 determines the opening pattern (opening time) of the ordinary electric accessory 522 according to the result of the hit / fail determination of the ordinary symbol. The ordinary symbol lottery processing means 145 holds an ordinary electric accessory opening pattern table that is referred to when determining an opening pattern (opening time) of the ordinary electric accessory 522. The opening pattern (opening time) of the ordinary electric accessory 522 is set to "0.2 seconds" when the electric chew support function (opening extension function) is not operating, and the electric chew support function (opening extension function) is set. If it is operating, "5.8 seconds" is set. The opening pattern of the ordinary electric accessory 522 may be different depending on the type of the hit symbol of the ordinary symbol. For example, when the electric chew support function (opening extension function) is operating as the opening pattern of the ordinary electric accessory 522, if the hit symbol of the ordinary symbol is symbol A, "3 seconds open x 1 time → 2. 8 seconds open x 1 time (total open time 5.8 seconds) ", and if the hit symbol of the normal symbol is symbol B," 2.8 seconds open x 1 time → 3 seconds open x 1 time (total open time 5) .8 seconds) ".

When the result of the hit / fail determination of the special symbol is a jackpot, the special game control means 150 determines the execution time (demo time) of the jackpot start demo and the jackpot end demo according to the determined jackpot type (symbol group). Determine the execution time (round time) of the round game. Then, the special game control means 150 instructs the effect control board 200 side to execute the effect control command (referred to as "big hit start demo command") and the jackpot end demo effect. An effect control command (referred to as a “big hit end demo command”) is generated and stored in the command storage area of the main information storage means 180. The jackpot start demo command is also an opportunity for the effect control board 200 side to determine the content of a series of jackpot start demo effects (big hit start demo effect, round effect, jackpot end demo effect) developed during the jackpot game. Become. Further, the special game control means 150 generates an effect control command (referred to as a “round effect designation command”) for instructing the start of the round effect corresponding to each round game in each round game during the big hit game. , This is stored in the command storage area of the main information storage means 180. This round effect designation command includes information on the current number of rounds and information on opening and closing of the grand prize opening 54.

The symbol display control means 155 includes a special symbol display control means 156 and a normal symbol display control means 157. The special symbol display control means 156 causes the first special symbol display device 71 to variably display the first special symbol according to the fluctuation pattern (variation time) of the first special symbol, and confirms and displays the first special symbol after the fluctuation display. Let me. Further, the special symbol display control means 156 causes the second special symbol display device 72 to variably display the second special symbol according to the fluctuation pattern (variation time) of the second special symbol, and displays the second special symbol after the fluctuation display. Confirm display. The special symbol display control means 156 has a special symbol game timer for managing the time (variable time, fixed display time) related to the display of the first special symbol and the second special symbol. The operating states of the first special symbol display device 71 and the second special symbol display device 72 are monitored based on the special symbol game status of the main information storage means 180. The special symbol display control means 156 requests the effect control board 200 to confirm the decorative symbol when the fluctuation of the special symbol is stopped (that is, at the timing when the value of the special symbol game timer becomes “0”). Generates an effect control command (referred to as "fluctuation stop command"). The normal symbol display control means 157 causes the normal symbol display device 75 to variably display the normal symbol according to the fluctuation pattern (variation time) of the normal symbol, and confirms and displays the normal symbol after the fluctuation display. The normal symbol display control means 157 has a normal symbol game timer for managing the time (variable time, fixed display time) related to the display of the normal symbol. The operating state of the normal symbol display device 75 is monitored based on the normal symbol game status of the main information storage means 180.

Further, the special symbol display control means 156 issues an effect control command (referred to as "standby demo command") that triggers the execution of the standby demo effect (customer waiting demo effect) when the game is interrupted for a predetermined time or longer. It is generated and stored in the command storage area of the main information storage means 180. "The interrupted state of the game continues for a predetermined time or longer" means that the period during which the operation holding ball of the special symbol does not exist and the variation display of the special symbol is not performed continues for a predetermined time or longer. If the period in which the game ball is not launched continues for a predetermined time or longer, or if the period in which the game ball is not entered in all the winning openings continues for a predetermined time or longer, the game is interrupted for a predetermined time or longer. It may be a continuous specification.

When the result of the hit / fail determination of the special symbol is a big hit, the electric accessory control means 160 outputs a control signal to the special electric accessory solenoid 543 as a big hit game process after confirming the special symbol, and outputs a control signal to the special electric accessory solenoid 543. The object 542 is controlled to open and close according to a predetermined operation pattern. In the jackpot game, one opening / closing operation of the special electric accessory 542 is set as one round game (unit game), and the round game is continuously executed for a predetermined number of rounds. The electric accessory control means 160 holds a large winning opening opening counter for storing the number of operations of the special electric accessory 542 (that is, the number of running rounds). Here, the operation end condition (end condition of the unit game) of the special electric accessory 542 in the big hit game is that a specified count number (“10” in the present embodiment) of game balls enters the big winning opening 54. That is, or the opening time of the large winning opening 54 has reached the maximum opening time (“29 seconds” in this embodiment).

Further, the electric accessory control means 160 outputs a control signal to the ordinary electric accessory solenoid 523 when the result of the hit / fail determination of the ordinary symbol corresponds to a hit, and the ordinary electric accessory 522 (No. 1) for a predetermined opening time. 2 Opening and closing control of the starting port 52) is performed. Here, as described above, the electric accessory control means 160 opens the normal electric accessory 522 for 0.2 seconds in the low base state in which the electric chew support function (opening extension function) is not operating. Then, in the high base state in which the electric chew support function (opening extension function) is operating, the normal electric accessory 522 is opened for 5.8 seconds. Here, the operation termination condition of the ordinary electric accessory 522 is that a predetermined number (“10” in this embodiment) of game balls have entered the second starting port 52, or that the second starting port 52 has. The opening time has reached the maximum opening time (“0.2 seconds” or “5.8 seconds” in this embodiment).

When the result of the winning / failing determination of the first special symbol or the second special symbol is a big hit, the game state control means 165 is based on the big hit type (type of symbol group) and the game state at the time of winning the big hit. The game state after the end of the jackpot game is determined, and the game state after the end of the jackpot game is switched.

Further, the game state control means 165 determines the variation pattern selection state after the end of the jackpot game based on the jackpot type (type of symbol group) when the jackpot game is executed, and after the end of the jackpot game. Switch the variable pattern selection state of.

Further, the game state control means 165 generates an effect control command (referred to as a “game state designation command”) including the current game state information and the variation pattern selection state information, and stores the command of the main information storage means 180. Store in the area.

The error monitoring control means 170 monitors the input information of the I / O port circuit 104, and inspects the magnetic detection signal by the magnetic sensor, the disconnection short circuit power supply abnormality signal, the radio wave detection signal by the radio wave sensor, the door / frame opening signal, and the like. , Determine whether the gaming machine is in an error state. In the case of an error state, an effect control command (“error effect designation command”) including the error information is requested to the effect control board 200 in order to indicate the error state effect. Although the description is omitted in FIG. 11 and the like, the door opening switch is a means for detecting whether or not the glass frame 5 is open, and the frame opening switch is for detecting whether or not the front frame 2 is open. The back set release switch is a means for detecting whether or not the back set board 30 is open. Further, the magnetic sensor and the radio wave sensor are detection means for detecting so-called fraudulent gaming activities.

The main information storage means 180 includes random number value information acquired in the special symbol game and the normal symbol game, operation holding ball information of the special symbol and the normal symbol, and a game state (probability fluctuation function, fluctuation time) related to the special symbol game and the normal symbol game. Information on shortening function, electric chew support function), information on variable pattern selection status, result information of hit / fail judgment of special symbols and ordinary symbols (big hit, miss), stop symbols related to special symbols and ordinary symbols (including symbol group) Information, information on variation patterns (including variation addition patterns) of special symbols and ordinary symbols, information on jackpot games (number of rounds, opening time, opening mode (number of openings per round game), etc.), special symbol display device 71, It is configured to temporarily store status information indicating the operating state of 72, status information indicating the operating state of the special electric accessory 542, information of effect control command data, and the like, and a predetermined storage for storing each information. It has an area.

The command transmission / reception means 190 is configured to transmit various effect control command data stored in the command storage area of the main information storage means 180 to the effect control board 200 by a parallel transmission method when a command transmission request is made. Has been done. Each effect control command has a 2-byte configuration including 1-byte MODE data and 1-byte EVENT data. In order to distinguish MODE and EVENT, Bit7 of MODE data is "1". Bit7 of EVENT data is set to "0". When this information is transmitted as valid, a strobe signal is output at each transmission timing of MODE and EVENT. As a general rule, the effect control command generated in each process is transmitted as one command for each interrupt cycle according to the order set in the command storage area of the main information storage means 180.

<Processing on the main control board side>
Next, the procedure of the operation processing on the main control board 100 will be described with reference to the flowcharts of FIGS. 14 to 27. The processing on the main control board 100 side includes a main control side main processing and a main control side timer interrupt processing.

<< Main processing on the main control side >>
14 to 15 are flowcharts showing main processing on the main control side of the main control board 100. In this main control side main process, after the security check of the main CPU 101 is performed by resetting when the power is turned on, the program is started and the processes after S1 are started.

First, as an initial setting required when the power is turned on, the start address is set as the initial value of the stack area in the stack pointer (S1), and the access permission of the RAM 103 is granted (S2). Subsequently, a vector table in which the start address of the program to be processed when a timer interrupt occurs is set (S3), and an initial value is set in the internal register of the main CPU 101 (S4).

Subsequently, it is determined whether or not the RAM clear switch is turned on (S5). When the RAM clear switch is turned on (S5: YES), the entire area of the RAM 103 is zero-cleared in S9 described later. On the other hand, when the RAM clear switch is not turned on (S5: NO), the value of the power off information flag is read to determine whether or not the power off normal information is stored (S6).

Here, when the information on the normal power off is stored (S6: YES), the checksum is calculated for the predetermined area of the RAM 103 (S7). Then, it is determined whether or not this checksum is 0, that is, whether or not the checksum is normal (S8). Note that the checksum at power-on calculated here includes the complement of the checksum calculated in the power-off process described later, so if it is backed up normally, the checksum at power-on will be checked. Sam becomes "0". In this way, it is determined at the time of turning on the power whether or not the information stored in the RAM 103 before the power is turned off is correctly backed up. At this time, if the checksum is normal (S8: YES), the process proceeds to S12, which will be described later, in order to return to the state before the power was turned off. On the other hand, when the checksum is abnormal (S8: NO), the entire area of the RAM 103 is cleared to zero (S9). Next, the initialization data at the time of turning on the power is set in the RAM 103 (S10). Subsequently, in order to initialize the effect display device 70, initialize the effect lamp LP, and the like, an effect control command (“effect initial command”) to the effect control board 200 is requested (S11).

Next, in the power-off / recovery setting process, the power-on normal information is set, various errors are initially set, and communication with the payout control board 400 is initially set in the RAM 103 (S12). Here, as the setting of the power-on normal information, in order to save that the power-on was performed correctly, the power-on normal data is stored in the power-off information flag, and the information of the power-off occurrence is initialized. Turn off the power off confirmation flag. Next, the data transfer source address, the data transfer destination address, and the number of transfer bytes are set, and the data corresponding to the number of transfer bytes is transferred (S13). Then, the value of the special symbol game status at the time of power off is read, and the power off / return process related to the special symbol game is performed (S14).

Subsequently, a transmission request for an effect control command (“power off / return command”) at the time of power failure / recovery between the main control board 100 and the effect control board 200 is performed (S15). This power-off / recovery command includes information on the communication line inspection, the operating state of the special symbol, the number of probability fluctuations, the number of time reductions, the number of easy ball entry states, the fluctuation pattern selection state, and the error state. The untransmitted command request before the power is turned off is cleared. Next, in the symbol storage number command request processing, the information on the number of operation-holding balls of the first special symbol and the second special symbol when the power is turned off is read, and an effect control command including the information on the number of operation-holding balls is requested ( S16).

Subsequently, a return setting is made to return the normal electric accessory 522 to the state before the power is turned off (for example, the second start port 52 is in the open state) (S17). Further, a return setting is made to return the special electric accessory 542 to the state before the power is turned off (for example, the large winning opening 54 is opened) (S18). Subsequently, the value of the probability change flag is read, and the operating state of the probability fluctuation function of the special symbol when the power is turned off is set (S19). The probability variation flag is a flag for setting the operation probability (high probability or low probability) of the special symbol game (a flag indicating that the probability fluctuation function of the special symbol is operating). Next, in order to activate the timer interrupt, a predetermined count value is set as the initial setting of the CTC circuit of the main control microcomputer 110, and the timer interrupt is generated every 4 ms (S20). Subsequently, interrupt prohibition is set to prohibit the occurrence of timer interrupt processing (S21). Then, in preparation for restarting the watchdog timer, Clear Word 1 (
“55H”) is set (S22).

Next, in order to determine the occurrence of the power outage, the value of the power outage confirmation flag is read, and it is determined whether or not the power outage has occurred (S23). If the power is not cut off, the initial value random number update process is executed (S24).

(Starting port monitoring control process)
First, the start port monitoring control process (S64) will be described. FIG. 18 is a flowchart showing details of the start port monitoring control process (S64).

First, it is determined whether or not the winning of the game to the first starting port 51 is detected (S201). When the winning of the first starting port 51 is detected (S201: YES), it is determined whether or not the number of balls on hold for operation of the first special symbol is less than the upper limit of 4 (S202).

When the number of balls on hold for operation of the first special symbol is less than 4 (S202: YES), the lottery random number values related to the first special symbol game include a random value per special symbol, a random value per symbol, and a special symbol. The fluctuation pattern random value is acquired, and each random value is stored in the first special symbol hold storage area (hold n storage area) of the main information storage means 180 according to the ball entry order (S203). Then, as an update of the number of balls on hold for operation of the first special symbol, the value of the number of balls on hold for the first special symbol is added by 1 (S204), and the winning check of the first starting port 51 is completed.

Subsequently, it is determined whether or not the winning of the game to the second starting port 52 is detected (S205). When the winning of the second starting port 52 is detected (S205: YES), it is determined whether or not the number of balls on hold for operation of the second special symbol is less than the upper limit of 4 (S206). When the number of balls on hold for operation of the second special symbol is less than 4 (S206: YES), the lottery random value related to the second special symbol game is a random value per special symbol, a random value per symbol, or a special symbol. The fluctuation pattern random value is acquired, and each random value is stored in the second special symbol hold storage area (hold n storage area) of the main information storage means 180 according to the ball entry order (S207). Then, as an update of the number of balls on hold for operation of the second special symbol, the value of the number of balls on hold for the second special symbol is added by 1 (S208), and the winning check of the second starting port 52 is completed.

Subsequently, whether or not the number of reserved balls for the first special symbol or the second special symbol has been updated, that is, whether or not the number of reserved balls for the first special symbol or the second special symbol has been added in S204 or S208. (S209). When the number of operation-holding balls is updated (S209: YES), a symbol storage number command including information on the number of operation-holding balls of the first special symbol and the second special symbol is generated, and this is used as the main information storage means. It is stored in the command storage area of 180 (S210).

Next, the state of the game machine is confirmed, and it is determined whether or not it is the pre-determination timing (S211). In the case of the pre-judgment timing (S211: YES), in order to generate pre-reading judgment information based on various random numbers acquired at the time of winning the start opening, a special symbol hit disorder is generated from the hit random number buffer (hold n storage area or register, etc.) A numerical value is read out and a pre-judgment is made (S212). Then, a pass / fail pre-determination command including the information of the pre-determination result (pre-determination number) is generated, and this is stored in the command storage area of the main information storage means 180 (S213).

In addition, the symbol random number value per special symbol is read from the hit symbol random number buffer, and the symbol pre-determination is performed (S214).

(Special symbol change start monitoring control processing)
Next, the special symbol change start monitoring control process (S68) will be described. FIG. 19 is a flowchart showing details of the special symbol change start monitoring control process (S68).

In this special symbol change start monitoring control process (S68), the special symbol change start monitoring process described later is performed on the special symbol side of the first special symbol and the second special symbol that satisfies the fluctuation start condition. (S310) is executed. When both the first special symbol and the second special symbol satisfy the fluctuation start condition, the processing on the second special symbol side is preferentially executed as described above.

First, it is determined whether or not the jackpot is being hit (S301). Subsequently, whether both the first special symbol and the second special symbol are waiting for fluctuation, that is, whether the first special symbol game status and the second special symbol game status are both "00H (waiting for fluctuation)". It is determined whether or not (S302).

Subsequently, it is determined whether or not the number of reserved balls for operation of the second special symbol is "0" (S303), and if the number of reserved balls is not "0" (S303: NO), the second special It is considered that the symbol variation start condition is satisfied, and the address of the second special symbol variation start monitoring table (addresses of various tables used in the subsequent processing and addresses of the RAM storage area) is set (S304). , The process shifts to the special symbol change start monitoring process (S310) on the second special symbol side. That is, in the present embodiment, when the operation holding ball of the second special symbol exists, the operation holding ball of the second special symbol has priority regardless of the presence or absence of the operation holding ball of the first special symbol. It is supposed to be digested. The details of this special symbol change start monitoring process (S310) will be described later with reference to FIG. 68.

On the other hand, when the number of balls on hold for operation of the second special symbol is "0" (S303: YES), it is determined whether or not the number of balls on hold for operation of the first special symbol is "0" (S305). .. Here, when the number of reserved balls is not "0" (S305: NO), it is considered that the change start condition of the first special symbol is satisfied, and the address of the first special symbol change start monitoring table (hereinafter). After setting (addresses of various tables and addresses of RAM storage areas) used in the processing (S306), the process proceeds to the special symbol fluctuation start monitoring processing (S310) on the first special symbol side.

If the fluctuation start conditions of the first special symbol and the second special symbol are not satisfied (S301: YES, S302: NO, S305: YES), the special symbol fluctuation start monitoring process (S310) is skipped. ..

(Special symbol change start monitoring process)
Next, the special symbol change start monitoring process (S305, S309) will be described. FIG. 20 is a flowchart showing the details of the special symbol change start monitoring process (S305, S309).

In this special symbol change start monitoring process (S305, S309), the change start of this time is started by referring to the first special symbol change start monitoring table or the second special symbol change start monitoring table set in S304 or S308 described above. The processing on the target special symbol side will be executed, but since the processing method is the same for the first special symbol side and the second special symbol side, except for special cases, the processing method on the first special symbol side It will be described collectively without distinguishing whether it is a process or a process on the second special symbol side.

First, the number of pending balls on the special symbol side, which is the target of the start of this fluctuation, is subtracted by 1 (S311). Then, a symbol storage number command including information on the number of operation-holding balls of the first special symbol and the second special symbol after subtraction is generated, and this is stored in the command storage area of the main information storage means 180 (S312). Subsequently, the special symbol hold storage area on the special symbol side that is the target of this fluctuation start is accessed, and the random value per special symbol and the special symbol per special symbol stored in the earliest reserved storage area (hold 1 storage area). Since the symbol random value and the special symbol variation pattern random value are read out in order and these random values are used for the special symbol hit / fail determination process (S320), the symbol determination process (S330), and the variation pattern selection process (S423) described later. It is transferred to the special symbol hit / miss determination area, the special symbol determination area, the special symbol variation pattern determination area, and the special symbol variation addition pattern determination area of the main information storage means 180 (S313). Further, as the update of the hold storage area, the hold ball information stored in the hold 2 storage area to the hold 4 storage area is shifted to the lower hold storage area, and the hold 4 storage area is cleared to zero (S314).

Subsequently, the special symbol hit / miss determination process is executed (S320). In the special symbol winning / failing determination process (S320), first, the special symbol winning / failing lottery table is acquired. At this time, if the game state is the special symbol probability change state, the high-probability winning / losing lottery table is acquired, and if the gaming state is the normal state, the low-probability winning / losing lottery table is acquired. Next, the random value per special symbol is read from the special symbol hit / miss determination area of the main information storage means 180. Then, with reference to the special symbol winning / failing lottery table, the winning / failing determination of the special symbol is executed based on the random number value per special symbol. Further, the values corresponding to the hit / fail determination result (big hit data “55H”, loss data “00H”) are stored in the special symbol determination flag of the main information storage means 180.

Subsequently, the symbol determination process is executed (S330). In the symbol determination process (S330), the stop symbol and the character effect number (variable additional symbol information) of the special symbol are determined according to the result of the hit / fail determination. Then, the stop symbol (symbol group) and the character effect number of the special symbol determined this time are stored in the symbol storage area of the main information storage means 180. The character effect number is the type of the determined stop symbol (symbol group) and the operating state of the probability fluctuation function of the special symbol and the normal symbol (probability change on of the special symbol / probability change off of the special symbol / probability change on of the normal symbol). / Determined based on the combination with (4 patterns of probability variation off of normal symbols). If the result of the hit / fail judgment is incorrect, the character effect number "0" is determined.

Subsequently, it is determined whether or not the result of the hit / fail determination of the special symbol corresponds to a big hit (S342). If the result of the hit / fail determination of the special symbol is incorrect (S342: NO), the process proceeds to S351.

If the result of the hit / fail judgment of the special symbol is a big hit (S342: YES), after the big hit game is completed, based on the type of the symbol group (big hit type) determined in S330 above and the game state at the time of winning the big hit. The number of probability fluctuations is determined as the number of times the probability variation function of the special symbol is activated (S345). Further, based on the type of symbol group (big hit type) determined in S330 and the game state at the time of winning the big hit, the number of times the fluctuation time shortening function of the special symbol is activated after the end of the big hit game is the number of times the fluctuation time is shortened. Is determined (S346). Further, based on the type of the symbol group (big hit type) determined in S330 and the game state at the time of winning the big hit, the number of electric support is determined as the number of times the electric chew support function is activated after the big hit game is completed ( S347). The determination result (number of probability fluctuations, number of times of shortening of fluctuation time, number of times of electric support) is stored in the time reduction number storage area and the electric support number storage area of the main information storage means 180. Subsequently, based on the type of symbol group (big hit type) determined in S330, the operation pattern of the special electric accessory 542 during the big hit game (round game) is set (S348). Specifically, as the operation pattern of the special electric accessory 542, the specified number of rounds of the big hit game, the opening pattern (maximum opening time) of the big winning opening 54 in each round, and the like are set.

Next, the variation pattern selection state after the end of the big hit game is set based on the type of the symbol group determined in S330 and the current game state (S349). Subsequently, the demo production time (hit start demo time and hit end demo time) of the special game (big hit game) is set based on the type of the symbol group determined in S330 (S350). Next, the special symbol hit / miss determination area and the special symbol symbol determination area of the main information storage means 180 used in the above-mentioned special symbol hit / miss determination process (S320) and symbol determination process (S330) are cleared (S351). Then, the special symbol game status on the special symbol side to be changed this time is changed from "00H (standby)" to "01H (start of fluctuation)" (S352).

(Special symbol control processing)
Next, the special symbol control process (S65) will be described. FIG. 21 is a flowchart showing the details of the special symbol control process (S65).

First, it is determined whether or not the special electric accessory 542 is not operating, that is, whether or not the special electric accessory game status is "00H (waiting for hit)" (S401). Subsequently, when the special electric accessory 542 is not operating (S401: YES), it is determined whether or not the second special symbol game status is "00H (standby)" (S402).

When the second special symbol game status is not "00H (waiting)" (S402: YES), the second special symbol control table (used in the subsequent processing) is used to execute the process related to the second special symbol. The address of various tables and the address of the RAM storage area) are set (S403), and the process proceeds to the special symbol control general-purpose processing (S410). On the other hand, when the second special symbol game status is "00H (waiting)" (S402: NO), the first special symbol control table (in the subsequent processing) is executed in order to execute the process related to the first special symbol. The addresses of the various tables used and the addresses of the RAM storage areas) are set (S404), and the process proceeds to the special symbol control general-purpose processing (S410).

In the special symbol control general-purpose processing (S410) described below, the first special symbol control table or the second special symbol control table set in S403 or S404 described above is used, and the special that is the target of this change is used. The processing on the symbol side will be executed, but since the processing method is the same for the first special symbol side and the second special symbol side, is it the processing on the first special symbol side except in special cases? , The second special symbol side processing will be described collectively without distinguishing whether it is the processing. The details of this special symbol control general-purpose processing (S410) will be described later with reference to FIG.

(Special symbol control general-purpose processing)
Subsequently, the special symbol control general-purpose processing is executed (S404, S407). Here, FIG. 22 is a flowchart showing the details of the special symbol control general-purpose processing (S404, S407).

In this special symbol control general-purpose processing (S404, S407), branch processing (S411 to S414) for shifting to processing according to the value of the special symbol game status ("01H", "02H", "03H") is executed. To do. First, it is determined whether or not the special symbol game status on the special symbol side that is the target of this change is not 0 (S411). When the special symbol game status is not "00H" (S411: YES), it is determined whether or not the special symbol game status is "01H (start of fluctuation)" (S412). When the special symbol game status is "01H" (S412: YES), the process proceeds to the special symbol variation start process (S420). The details of this special symbol change start processing (S420) will be described later with reference to FIG. On the other hand, if NO in S412, it is determined whether or not the special symbol game status is "02H (changing)" (S413). When the special symbol game status is "02H" (S413: YES), the process proceeds to the special symbol changing process (S430). The details of this special symbol change processing (S430) will be described later with reference to FIG. 24. If NO in S413, it is determined whether or not the special symbol game status is "03H (stop symbol is being displayed)" (S414). When the special symbol game status is "03H" (S414: YES), the process proceeds to the process of displaying the special symbol stop symbol (S440). The details of this special symbol stop symbol display processing (S440) will be described later with reference to FIG. 25.

(Special symbol change start processing)
Next, the special symbol variation start processing (S420) will be described. FIG. 23 is a flowchart showing the details of the special symbol variation start processing (S420).

First, a special symbol variation pattern table is acquired based on the result of the winning / failing lottery, the variation pattern selection state, and the like (S421). Subsequently, the special symbol variation pattern random value is read out from the special symbol variation pattern determination area of the main information storage means 180 (S422). Then, with reference to the special symbol variation pattern table, one of a plurality of types of variation patterns is selected based on the special symbol variation pattern random value (S423).

Next, the fluctuation time corresponding to the fluctuation pattern selected this time is set (S424). Then, as a setting for starting the variation of the special symbol, the variation time is stored in the special symbol game timer of the symbol display control means 165 (S425), and the variation start command to the effect control board 200 is generated (S426). As the variation start command, in order to start the symbol variation effect on the effect display device 70, a communication inspection command, a variation addition symbol information designation command, a variation pattern designation command, and a symbol designation command are generated in order, and these are used as the main information storage means. It is stored in the command storage area of 180.

Subsequently, the content of the special symbol variation pattern determination area of the main information storage means 180 used for determining the variation pattern is cleared (S427). Then, the special symbol game status is changed from "01H (start of fluctuation)" to "02H (during fluctuation)" (S428).

(Processing during special symbol change)
Next, the processing during special symbol change (S430) will be described. FIG. 24 is a flowchart showing the details of the special symbol changing process (S430).

First, in order to display the variation of the special symbol, the display pattern number switching process of the special symbol is executed (S431). In this display pattern number switching process (S431), display pattern number data of a special symbol is generated at each predetermined switching time. This display pattern number data is output to the first special symbol display device 71 or the second special symbol display device 72 in the LED output process (S73) in order to display the special symbol in a variable display or a definite display.

Next, it is determined whether or not the special symbol game timer has reached "0 (timeout)", that is, whether or not the fluctuation time of the special symbol has expired (S432). When the fluctuation time of the special symbol ends (S432: YES), the stop symbol of the special symbol to be confirmed and displayed on the first special symbol display device 71 or the second special symbol display device 72 is set (S433). Subsequently, a fluctuation stop command for instructing the effect control board 200 to confirm and display the decorative symbol is generated, and this is stored in the command storage area of the main information storage means 180 (S434).

Next, "500 (ms)" is stored as the fixed display time in the special symbol game timer (S435). The "fixed display time" is a time for definitively stopping and displaying the stopped symbol when the special symbol is stopped fluctuating. Then, the special symbol game status is changed from "02H (during change)" to "03H (during stop symbol display)" (S436).

(Processing during special symbol stop symbol display)
Next, the special symbol stop symbol display processing (S440) will be described. FIG. 25 is a flowchart showing the details of the special symbol stop symbol display processing (S440).

First, it is determined whether or not the special symbol game timer has reached "0 (timeout)", that is, whether or not the final display time of the special symbol (stop symbol) has expired (S441). Here, when the final display time of the special symbol ends (S441: YES), the special symbol game status is changed from "03H (stop symbol display)" to "00H (standby)" (S442).

Subsequently, it is determined whether or not the hit / fail determination data stored in the special symbol determination flag of the main information storage means 180 is the jackpot data “55H” (S443). When the hit / fail judgment data is jackpot data (S443: YES), the operation of the probability fluctuation function of the special symbol is stopped (S444), the operation of the function for shortening the fluctuation time of the special symbol is stopped (S445), and the electric chew support function is activated. Stop (S446) is performed in order. Specifically, "00H (off)" is set in the probability change flag, and "00H" is set in the probability fluctuation count counter, the fluctuation time shortening count counter, and the ball entry easy state count counter to clear zero.

Next, as the start demo setting process of the special game, the start demo display time is set and an effect control command (big hit start demo command) for instructing the start of the start demo effect is generated (S447). Subsequently, the number of executions of the fluctuation pattern selection state (variation pattern selection state count counter) is cleared to zero (S448). In addition, the special electric accessory game status is changed from "00H (waiting for hit)" to "01H (special game)" (S449). Then, "00H" is set in order to clear the contents of the pass / fail determination flag (S450).

On the other hand, when the hit / fail determination data is not the jackpot data (S443: NO), it is determined whether or not the probability variation function of the special symbol is operating (S451). When the probability fluctuation function of the special symbol is operating (S451: YES), the probability fluctuation counter of the main information storage means 180 is decremented by 1 as the digestion of the number of fluctuations of the special symbol this time (step S452). .. Subsequently, it is determined whether or not the probability fluctuation number counter is zero (step S453). When the probability fluctuation number counter is zero (S453: YES), the operation of the probability fluctuation function of the special symbol is stopped (S454). If the probability fluctuation counter after subtraction is not zero (S453: NO), S454 is skipped and the process proceeds to S455.

Next, it is determined whether or not the fluctuation time shortening function of the special symbol is operating (S455). When the function for shortening the fluctuation time of the special symbol is operating (S455: YES), the time reduction counter of the main information storage means 180 is decremented by 1 as the digestion of the number of fluctuations of the special symbol this time (step S456). .. Subsequently, it is determined whether or not the fluctuation time reduction count counter is zero (step S457). When the fluctuation time reduction counter is zero (S457: YES), it is considered that the number of terminations of the special symbol time reduction state has been reached, and the operation of the fluctuation time reduction function of the special symbol is stopped (S458). If the fluctuation time reduction number counter after subtraction is not zero (S457: NO), S458 is skipped and the process proceeds to S459.

Next, it is determined whether or not the electric chew support function is operating (S459). When the electric chew support function is operating (S459: YES), the electric support number counter of the main information storage means 180 is decremented by 1 as the digestion of the number of fluctuations of the special symbol this time (step S460). Subsequently, it is determined whether or not the electric support count counter is zero (step S461). When the electric support count counter is zero (S461: YES), the operation of the electric chew support function is stopped (S462), assuming that the end number of the easy ball entry state has been reached. If the number of times of electric support after subtraction is not zero (S461: NO), S462 is skipped and the process proceeds to S463.

Next, the fluctuation pattern selection state count counter of the main information storage means 180 is subtracted by 1 (S463). Then, the fluctuation pattern selection state is updated (S464). Specifically, the number of times of the variation pattern selection state of the main information storage means 180 is referred to, and it is determined whether or not the number of executions of the current variation pattern selection state has reached the preset number of ends, and the number of ends is determined. If it has been reached, the state is switched to the fluctuation pattern selection state specified next. On the other hand, if the number of ends has not been reached, the current fluctuation pattern selection state is maintained.

Next, an effect control command (game state designation command) including the current game state information and fluctuation pattern selection state information updated in S451 to S464 described above is generated, and this is stored in the command storage area of the main information storage means 180. Store in (S465). On the effect control board 200 side, the effect mode is set and updated based on the information of the game state designation command.

(Special electric accessory control process)
Next, the special electric accessory control process (S66) will be described. 26 to 27 are flowcharts showing the details of the electric accessory control process (S66).

First, it is determined whether or not the special electric accessory game status is "01H (special game)" (S501). When the special electric accessory game status is "01H" (S501: YES), the special game process is executed in the subsequent processes. In this special game process, first, it is determined whether or not the special electric accessory 542 is in operation (S502). When the special electric accessory 542 is not operating (S502: NO), it is determined whether or not it is the operation start time of the special electric accessory 542 (S503). The operation start time of the special electric accessory 542 is a timing at which the operation of the special electric accessory 542 is started in each round game.

When it is the operation start time of the special electric accessory 542 (S503: YES), an effect control command (round effect designation command) is generated to start the round effect, and this is stored as a command of the main information storage means 180. Store in the area (S504). The effect control board 200 side executes a round effect corresponding to each round game during the special game based on the information of the round effect designation command (information such as the current number of rounds). Then, the operation of the special electric accessory 542 is started (S505), and the processes S506 to S510 are executed as the processing during the operation of the special electric accessory 542.

As a process during operation of the special electric accessory 542, it is determined whether or not the game ball has won the specified count number (maximum number of winnings) in the large winning opening 54 (S506), and the operating time of the special electric accessory 542 is also determined. It is determined whether or not (opening time) has elapsed (S507). At this time, if the game ball wins only the specified count number (maximum number of winnings) in the large winning opening 54 (S506: YES) or the operating time of the special electric accessory 542 has elapsed (S507: YES), it is special. The operation of the electric accessory 542 is stopped (S508). Then, it is determined whether or not the number of continuous operations of the special electric accessory 542 has reached a predetermined number of predetermined rounds (S509). When the number of continuous operations has not reached the specified number of rounds (S509: NO), the number of continuous operations of the special electric accessory 542 is incremented by 1 (S510).

On the other hand, when the number of continuous operations of the special electric accessory 542 has reached the specified number of rounds (S509: YES), the process proceeds to S511 and the end demo display time is set as the hit end demo setting process for the special game. At the same time, an effect control command (big hit end demo command) for instructing the start of the end demo effect is generated (S511).

Subsequently, the fluctuation time reduction count information set in S346 is stored in the fluctuation time reduction counter (S512). Further, the electric support count information set in S347 is stored in the electric support counter (S513).

Subsequently, with reference to the content of the probability fluctuation determination flag set in S343, it is determined whether or not the operation of the condition device is an operation by a specific symbol (so-called probability variation symbol) (S514). When the condition device is operated by the specific symbol (S514: YES), the probability fluctuation number counter (operating data) set in S345 is stored in the probability fluctuation number counter of the main information storage means 180, and the special symbol is stored. The operation of the probability fluctuation function of (S515) is started. On the other hand, when the condition device is not operated by the specific symbol (S514: NO), the non-operating data “00H” is stored in the probability fluctuation number counter and S515 is skipped.

Subsequently, it is determined whether or not the fluctuation time reduction count information stored in the time reduction counter is the fluctuation time reduction function operation data (data other than "00H") (S516). In the case of the fluctuation time shortening function operation data (S516: YES), the operation of the fluctuation time shortening function of the special symbol is started (S517). On the other hand, if it is not the fluctuation time shortening function operation data (S516: NO), S517 is skipped.

Subsequently, it is determined whether or not the electric support number information stored in the electric support number counter is the electric chew support function operation data (data other than "00H") (S518). When it is the electric chew support function operation data (S518: YES), the operation of the electric chew support function is started (S519 to S521). That is, the operation start of the probability fluctuation function of the normal symbol (S519), the operation start of the fluctuation time shortening function of the normal symbol (S520), and the operation start of the opening extension function of the normal electric accessory 522 (S521) are executed in order. On the other hand, if it is not the electric chew support function operation data, S519 to S521 are skipped.

Then, it switches to the fluctuation pattern selection state determined in S347 (S522). Subsequently, an effect control command (game state designation command) including the game state information after the special game and the variation pattern selection state information set in S512 to S522 described above is generated, and this is used by the main information storage means 180. Store in the command storage area (S523). The effect control board 200 side sets the effect mode after the special game based on the information of the game state designation command. Then, the special electric accessory game status is changed from "01H (special game)" to "00H (waiting state)" (S524).

<Recording the program code in ROM>
The program that defines each of the above processes is stored in the ROM 102 mounted on the main control microcomputer 110. Hereinafter, the storage area of the ROM 102 will be described with reference to FIG. 28. As shown in FIG. 28, the storage areas of the ROM 102 include the first program code area PCA1, the first program data area PDA1, the second program code area PCA2, the second program data area PDA2, the comment area CA, and the program management area PMA. , It is divided into 7 types of unused areas (shaded areas) between those areas. The program code that defines the operation related to the progress of the game is recorded in the first program code area PCA1, and the program data referred to by the program code stored in the program code area PCA1 is recorded in the first program data area PDA1. Is recorded. Further, a program code that defines an operation irrelevant to the progress of the game, for example, a test program for performing an operation test of the game machine, is recorded in the second program code area PCA2, and is recorded in the second program data area PDA2. Is recorded with program data referenced by the program code stored in the program code area PCA2. The program code recorded in each program code area is modularized for each function. Further, in the comment area CA, the manufacturer name of the manufacturer of the game machine PA, the model name (model name) of the game machine, and the creation date of the program code are recorded as character string data.

The program management area PMA is a 64-byte area located at the end of the ROM. In the program management area PMA, in addition to the header information in a predetermined format, the manufacturer code of the manufacturer, and the character string representing the product code of the game machine, the terminal address (end address) of the first program code area PCA1 and the second program code. The start address (start address) and end address of the area PCA2 are recorded. In addition, necessary setting data is recorded for the functions provided by the main control microcomputer 110, such as reset processing, interrupt initial setting, built-in register mapping method, and other various functions. The recording of data in the program management area PMA is usually performed by the creator of the program (game machine maker) writing and executing an assembly program for recording information.

Here, the ROM mounted on the main control board of the gaming machine must comply with a predetermined standard defined in order to prevent unauthorized modification. For the pachinko gaming machine, the program code area PCA1 and the program data area There is a restriction that the capacity of each PDA1 must not exceed 3KB. If you try to enhance the interest of pachinko gaming machines by elaborate production, the size of the program code related to the progress of the game will increase accordingly, so in general, the placement of program code and program data has as few blank areas as possible. It is considered that the arrangement is preferable. On the other hand, in the gaming machine of the present embodiment, the program code or the like is arranged by giving priority to the legibility of the list when the contents of the ROM are output as a dump list, rather than arranging the program code or the like without gaps. doing. The dump list is an output of all the data stored in the ROM as a list, and is a list in which the data expressed as a hexadecimal number and the characters represented by the data are written side by side. The dump list is output by the manufacturer of the ROM, an inspection agency, or the like when, for example, an illegal modification of the ROM is suspected, and its contents are scrutinized or collated with other information.

29 and 30, show (A) a first program code area, (B) an unused area, (C) a first program data area, (D) a second program code area, and (E) a second. For each of the program data area, (F) comment area, and program management area, a start address (start address) and a dump list of that area are illustrated. In the example dump list, the leftmost digit represents the upper three digits of the hexadecimal address indicating the data storage position, and the uppermost digit represents the lower one digit of the hexadecimal address (16 because of byte data representation). (Displayed in 2 decimal digits), <Sum> represents a checksum for error detection (the last 2 digits of the hexadecimal digit as a result of adding the same line). Further, the two-digit hexadecimal data displayed as the data existing at each address is a code of the program and data information stored in the address by using an assembly program.

As shown in these figures, in each area, data is written in each area with the position where the lower one digit of the address is "0" as the starting position. Further, as shown in FIG. 29B, the value of the unused area is set to "0" at all the addresses. Similarly, as shown in FIG. 30 (F), all the values of the prohibited area of the program management area are also set to "0". The use-prohibited area restricts the writing of setting values so that when the gaming machine equipped with the ROM has a function that cannot be used, the setting related to the function is not performed. Since the unused area can be easily recognized in this type of dump list, the boundary of each program code area or program data area can be easily recognized. In addition, it is possible to easily grasp that there is a function that cannot be used from the setting status of the zero value in the program management area.

Further, as shown in FIG. 30F, in the comment area and the program management area, the manufacturer name, product name, header information, manufacturer code and product code are indicated by addresses in which the upper digits are common and the lower digits are different from each other. It is placed in position. As a result, the manufacturer name, product name, header information, manufacturer code, and product code displayed as character strings at the right end of the dump list are all displayed in a vertically aligned state as character strings starting from the beginning of the line. Become. Such a display is convenient when extracting a manufacturer name or the like from a dump list.

The following is an example of an assembly code written for the purpose of recording data at a predetermined position in the ROM. The code shown below defines the writing of the ROM 102 shown in FIG. 28 to the comment area CA and the writing to the program management area PMA. In the assembly code below, the leftmost number is the line number of the assembly code, the second number from the left is the hexadecimal address indicating the data writing position, and the third number from the left is the hexadecimal code for the data to be written. It is expressed as. In the assembly code, for example, the pseudo instruction "ORG 2F00H" means to start recording data from the position specified by the hexadecimal address 2F00. Further, the pseudo command "DB'XXX'" means that the character string sandwiched between the apostrophes ('), which is the character recognition symbol, is written as the character code of the character string from which the recognition symbol is removed. The code from the 10637th line to the 10656th line defines the writing process to the comment area CA, and the code from the 10657th line to the 10683th line defines the writing process from the "header" to the "reset setting" of the program management area PMA. There is. Although the examples from the 10648th line onward are omitted, the setting value and the like can be written by repeating the same pseudo instruction even after the "interrupt initial setting". When the ROM in which the data is written by repeating such a pseudo instruction outputs the contents as a dump list, the dump list in the format illustrated in FIG. 30 (F) is output.

If an illegal modification of the ROM is suspected after the game machine is distributed, the ROM will be collected and inspected by the ROM manufacturer. In the inspection process, all the contents recorded in the ROM are output as a dump list and visually inspected. According to the recording method described above, when confirming the content output as a dump list, it is easy to confirm the presence or absence of modification, and illegal modification can be quickly detected.

In the present embodiment, an unused area is provided between the first program code area PCA1 and the first program data area PDA1, and the second program code area PCA2 and the second program data area PDA2, but the program It is not necessary to provide an unused area between the code area and the program data area. On the other hand, the first program code area PCA1 and the first program data area PDA1 in which the program code and the program data highly related to the progress of the game are stored, and the program having a low relevance to the progress of the game are stored. 2 A predetermined size (for example, 1) is provided between the program code area PCA2 and the second program data area PDA2 to facilitate distinction.
It is preferable to provide an unused area of 6 bytes or more, that is, one line or more of the dump list).

In addition, the model name (product name) stored in the comment area of the ROM is the same as the model name printed on the identification sticker attached to the main board case, ensuring the sameness as the information outside the program. By doing so, security is improved.

The present invention is not limited to the above-described embodiments and modifications, and can be appropriately improved as long as it does not deviate from the gist of the present invention. In addition, each component described in the above-described embodiment and modified example is appropriately combined, or a part of each component described in the above-described embodiment and modified example is deleted or converted by a well-known / conventional technique or the like. It is also included in the scope of the present invention.
