In the following, for the sake of easy understanding, the corresponding configurations in the embodiments of the invention are appropriately shown in parentheses or the like, but the present invention is not limited to the specific configurations shown in the parentheses or the like.

Means 1. A variable display means (reel unit 31) that variably displays a pattern (design),
A start condition detecting means (function S620 for determining that a start command of the CPU 102 has been generated) for detecting the establishment of a start condition for starting the variable display of the pattern, and
A lottery means (lottery processing function S505 of the CPU 102) for performing a lottery based on the establishment of the start condition, and
A display control means (reel control of the CPU 102) that starts the variable display of the pattern based on the satisfaction of the start condition and controls the display of the variable display means so as to obtain a stop result based on the lottery result of the lottery means. Processing function) and
If the lottery result of the lottery means is a winning result and a specific stop result (a stop result in which the combination of winning symbols stops on the valid line), a privilege (medal payout, transition to the BB state, etc.) is given to the player. In a gaming machine provided with a privilege granting means (CPU 102 medal payout processing function S507, BB state processing function S508, etc.).
A first process executing means (CPU102) that periodically performs a first process (timer interrupt process) including a first update process (delay counter process in timer interrupt process) that updates a predetermined value (value of the delay counter 111d).
A second process execution means (CPU102) that irregularly performs a second process (pre-start preparatory process) including a second update process (S609 in the pre-start preparatory process) for updating the predetermined value (value of the delay counter 111d). When,
A determination means (S620 in the pre-start preparation process) for determining whether or not a specific condition (generation of a start command) based on an operation by the player is satisfied, and
Acquisition process (basic random number acquisition process S801) for acquiring numerical information (count value of basic random number generator 150) as a random number used for the lottery or a basic random number that is the source of the random number based on the establishment of the start condition. ), And the acquisition process execution means (CPU102)
When the start condition is satisfied, the delay process (delay process S622 and delay counter process S117) delays the acquisition timing at which the acquisition process execution means acquires the numerical information from the timing at which the start condition is satisfied based on the predetermined value. ) Is provided with a delay processing execution means (CPU102).
The second processing execution means is configured to repeat the second processing from at least the second specific condition (performing S602 or S603 in the start waiting processing) to the satisfaction of the specific condition. A game machine characterized by that.

According to this means, as the process of updating the predetermined value, there are a first update process in the first process performed periodically and a second update process performed in the second process. Then, the random number used for the lottery or the numerical information as the basic random number that is the source of the random number is acquired based on the establishment of the start condition, and the start condition is satisfied based on the predetermined value updated in each update process. It is acquired at a timing delayed from the timing. With such a configuration, even if the numerical information as a random number or a basic random number becomes a value that wins the lottery at a fixed cycle and the start condition is satisfied at that timing, the random number or the basic is performed. By delaying the acquisition timing of the numerical information as a random number, it is possible to prevent the value that wins the lottery from being acquired.

Further, since the second process is repeated at least from the time when the second specific condition is satisfied to the time when the specific condition is satisfied, the second update process is also repeated during the period. Here, by making the establishment of the specific condition based on the operation by the player, the time during which the second process can be repeated can be made random, and it is performed until the specific condition is satisfied. The number of processing times of the second update processing can be random.

Furthermore, when the establishment of the specific condition is based on the operation by the player, the operation is illegally performed so that the time from the establishment of the second specific condition to the establishment of the specific condition is constant. There is a possibility. However, in this configuration, since the second processing is performed irregularly, even if the time from the establishment of the second specific condition to the establishment of the specific condition is fixed, the second processing is performed during such a period. 2 It is difficult to keep the number of times of processing constant. Further, the predetermined value is updated by the second update process performed in the second process and the first update process in the first process performed periodically. Therefore, it is difficult to set a predetermined value to a constant value in each game.

Means 2. The means 1 includes a start operation means (start lever 41) operated to start the variable display of the pattern, the determination means operates the start operation means, and the start condition detecting means operates the start condition.

In such a configuration, the time from the start to the end of the specific process changes depending on the start timing of the specific process. Therefore, the time from the start to the end of the second process can be made indefinite. Further, if the time from the start to the end of the specific process changes, the number of updates of the predetermined value in the specific process also changes, so that the number of updates of the predetermined value in the second process can be made random. Further, the end trigger of the specific process depends on the number of processes of the third process, and the fourth process is performed when the specific process is completed. Therefore, the fourth process is performed after the third process is completed. It is possible to shorten the interval until it is performed. As a result, it becomes possible to perform the fourth process using the process result of the third process according to the game situation and the like.

In any of the means 1 to 10, the delay processing executing means updates the predetermined value as the delay processing until it becomes a specific value (0) irrelevant to the predetermined value when the start condition is satisfied. A game machine characterized by performing processing.

According to this means, when the start condition is satisfied, the predetermined value is updated until it becomes a specific value irrelevant to the predetermined value at that time. With such a configuration, the period from the establishment of the start condition to the acquisition of numerical information as a random number or a basic random number corresponds to a value obtained by subtracting a predetermined value when the start condition is satisfied from a specific value. The period from the establishment of the start condition to the acquisition of numerical information as a random number or a basic random number can be made random.

Hereinafter, an embodiment when applied to a rotating cylinder type gaming machine, which is a kind of gaming machine, specifically, a slot machine, will be described in detail with reference to the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10 with the front door 12 closed, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 open, and FIG. 4 is a front view. A rear view of the door 12 and FIG. 5 are front views of the housing 11.

As shown in FIGS. 1 to 5, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The housing 11 is formed in a box shape with an open front surface as a whole, and is attached by hitting a nail against so-called island equipment at the time of installation in the game hall.

A front door 12 is attached to the front side of the housing 11 so as to be openable and closable. That is, the housing 11 is provided with a pair of upper and lower support shafts 13a and 13b on the left side when viewed from the front thereof, and the front door 12 is provided with bearing portions 14a at positions corresponding to the respective support shafts 13a and 13b. , 14b are provided. When the support shafts 13a and 13b are inserted into the bearing portions 14a and 14b, the front door 12 rotates around the opening / closing axis extending in the vertical direction connecting the support shafts 13a and 13b to the housing 11. It is movably supported, and the front opening side of the housing 11 can be opened or closed by rotating the front door 12. Further, the front door 12 is locked so as not to be opened by the locking device 20 provided on the back surface thereof. A key cylinder 21 integrated with the locking device 20 is provided on the upper right end side of the front door 12, and is configured so that the locked state is released by a predetermined key operation on the key cylinder 21.

A game panel 25 for notifying the player of the game state is provided near the center of the front door 12. Three vertically long display windows 26L, 26M, 26R are formed side by side on the game panel 25, and the inside of the slot machine 10 can be visually recognized through the respective display windows 26L, 26M, 26R. The display windows 26L, 26M, and 26R may be combined into one to form a common display window.

As shown in FIG. 3, the inside of the housing 11 is divided into upper and lower parts by a partition plate 30, and a reel unit 31 constituting a variable display means is attached to the upper part of the partition plate 30. The reel unit 31 includes a left reel 32L, a middle reel 32M, and a right reel 32R, which are formed in a cylindrical shape (annular shape), respectively. Each reel 32L, 32M, 32R is rotatably supported so that its central axis is the rotation axis of the reel. The rotation axes of the reels 32L, 32M, 32R are arranged on the same axis extending in the substantially horizontal direction, and the reels 32L, 32M, 32R correspond one-to-one with the display windows 26L, 26M, 26R. .. Therefore, a part of the surface of each reel 32L, 32M, 32R is visible through the corresponding display windows 26L, 26M, 26R, respectively. Further, when the reels 32L, 32M, 32R rotate in the forward direction, the surfaces of the reels 32L, 32M, 32R are projected as if they are moving from top to bottom through the display windows 26L, 26M, 26R.

Here, the configuration of the reel unit 31 will be briefly described.

Each reel 32L, 32M, 32R is connected to a stepping motor, and each reel 32L, 32M, 32R can be rotationally driven individually, that is, independently by driving each stepping motor. .. The stepping motor is set to rotate once by giving, for example, a drive signal of 504 pulses (hereinafter, also referred to as an excitation pulse), and the rotation position of the stepping motor, that is, the rotation position of the reel is set by this excitation pulse. Be controlled. Further, in the reel unit 31, reel index sensors for detecting that the reel has rotated once are installed in each reel 32L, 32M, 32R. Then, when the reel index sensor detects that the reel has rotated once, a detection signal is output to the main control device 101, which will be described later, each time the detection is performed. Therefore, the main control device 101 shifts the angular positions of the reels 32L, 32M, and 32R for each rotation based on the detection signal of the reel index sensor and the number of excitation pulses output until the detection signal is input. It can be confirmed and corrected.

On the outer peripheral surface of each reel 32L, 32M, 32R, a plurality of symbols as identification information are drawn in the long side direction (circumferential direction) thereof. More specifically, 21 symbols are drawn at equal intervals. Therefore, in order to switch a symbol at a predetermined position to the next symbol, it is necessary to output 24 pulses (= 504 pulses ÷ 21 symbols) of excitation pulses. Further, the main control device 101 grasps a symbol that is visible from the display windows 26L, 26M, and 26R by the number of excitation pulses output after the detection signal of the reel index sensor is input, and the display window. It is possible to perform control such as stopping a predetermined symbol at a position visible from 26L, 26M, 26R.

Next, the symbols drawn on the reels 32L, 32M, and 32R will be described.

FIG. 6 shows a symbol arrangement of the left reel 32L, the middle reel 32M, and the right reel 32R. As shown in the figure, 21 symbols are arranged in a row on each of the reels 32L, 32M, and 32R. In addition, numbers 0 to 20 are assigned to each reel 32L, 32M, 32R, and these numbers are symbols that can be visually recognized by the main control device 101 from the display windows 26L, 26M, 26R. It is a number for recognizing, and is not actually attached to the reels 32L, 32M, 32R. However, in the following description, the number will be used for explanation.

The symbols include a "star" symbol (for example, the 20th on the left reel 32L), a "cherry" symbol (for example, the 19th on the left reel 32L), a "young man" symbol (for example, the 18th on the left reel 32L), and " "Bell" symbol (eg, 17th on the left reel 32L), "Replay" symbol (eg, 16th on the left reel 32L), "White 7" symbol (eg, 15th on the left reel 32L), "Watermelon" symbol (eg, 15th on the left reel 32L) For example, there are eight types: the 14th on the left reel 32L) and the "red 7" symbol (for example, the 3rd on the left reel 32L). Then, as shown in FIG. 6, the number and arrangement order of various symbols are completely different in each reel 32L, 32M, 32R.

Each display window 26L, 26M, 26R is formed so that three of the 21 symbols attached to the corresponding reels can be visually recognized as the entire symbol. Therefore, when all the reels 32L, 32M, and 32R are stopped, 3 × 3 = 9 symbols can be visually recognized through the display windows 26L, 26M, and 26R.

In this slot machine 10, a total of five combination lines are set, three in parallel in the horizontal direction and two in the diagonal direction so as to connect the positions where these nine symbols can be visually recognized. ing. More specifically, as shown in FIG. 7, as a combination line in the horizontal direction, the upper line L1 connecting the upper symbols of each reel 32L, 32M, 32R and the middle symbol of each reel 32L, 32M, 32R are connected. A line L2 and a lower line L3 connecting the lower symbols of the reels 32L, 32M, and 32R are set. Further, as a combination line in the diagonal direction, a right-down line L4 connecting the upper design of the left reel 32L, the middle design of the middle reel 32M, and the lower design of the right reel 32R, and the lower design of the left reel 32L, the middle stage of the middle reel 32M. A design and a right-up line L5 connecting the upper design of the right reel 32R are set. Then, when the symbols are stopped in a predetermined combination on the activated combination line, that is, the valid line, a privilege of paying out a predetermined number of medals as a game medium is given as a winning result, or the game state is changed. Benefits are given.

FIG. 8 shows a combination of symbols to be won and a privilege to be given when the prize is won.

Small role prizes for which medals are paid out include bell prizes, watermelon prizes, single role prizes, and cherry prizes. If the "bell" symbols of each reel 32L, 32M, 32R stop side by side on the effective line, eight medals will be paid out as a bell prize, and the "watermelon" symbol of each reel 32L, 32M, 32R will be the effective line. If you stop side by side, 6 medals will be paid out as a watermelon prize, and if you stop side by side with the "Red 7" symbol, "Youth" symbol, and "White 7" symbol in order from the left on the valid line, One medal is paid out as one winning prize. In addition, when the "cherry" symbol on the left reel 32L stops on the effective line, two medals are paid out as a cherry prize. That is, in the case of cherry winning, any symbol may be used to stop on the effective line for the middle reel 32M and the right reel 32R. In other words, when the combination of the "cherry" symbol on the left reel 32L and any symbol on the middle reel 32M and the right reel 32R stops on the effective line, it can be said that the cherry winning is established. Therefore, if the "cherry" symbol stops at a position where a plurality of effective lines of the left reel 32L overlap (specifically, the upper and lower rows), a cherry prize will be established on each effective line, and as a result, a cherry prize will be established. 4 (= 2 × 2) medals are paid out. In the present embodiment, since the "cherry" symbol on the left reel 32L stops at the upper or lower stage and the cherry winning is established, four medals are paid out when the cherry winning is established. ..

There is a BB prize as a state transition prize in which only the transition of the game state is performed. When the "Red 7" symbols of the reels 32L, 32M, and 32R stop side by side on the effective line, the game state shifts to the big bonus state (hereinafter referred to as "BB state") as a BB prize.

There is a re-game prize as a prize to which benefits other than medal payout and transition of the game state are given. If the "replay" symbols of each reel 42L, 42M, 42R stop side by side on the effective line, as a re-game prize, medals will not be paid out or the game state will not be changed, but the next game will be played without inserting medals. The privilege of re-game that can play the game is given.

In the following, the combination of each winning symbol and the corresponding symbol will also be referred to as a combination of winning symbols. For example, the combination of replay symbols is a combination of symbols that wins a replay, that is, a combination of "replay" symbols, "replay" symbols, and "replay" symbols. Further, the symbols of the reels 32L, 32M, 32R corresponding to each winning symbol are also referred to as winning symbols. For example, the one-card combination symbol is a "red 7" symbol on the left reel 32L, a "youth" symbol on the middle reel 32M, and a "white 7" symbol on the right reel 32R.

On the lower left side of the game panel 25, a start lever 41 operated to start the rotation of each reel 32L, 32M, 32R is provided. The start lever 41 constitutes a start operation means or a start operation means that is operated to start rotating the reels 32L, 32M, 32R, that is, to start the variable display of the symbol. The start lever 41 is a lever that the player pushes and operates by hand when starting the game, and automatically returns to the initial position after the hand is released. Incidentally, the start lever 41 in the slot machine 10 is configured to take several tens of msec to automatically return to the initial position after the hand is released. When the start lever 41 is operated with a predetermined number of medals inserted, the reels 32L, 32M, and 32R start to rotate.

On the right side of the start lever 41, button-shaped stop switches 42 to 44 that are operated to individually stop the rotating reels 32L, 32M, and 32R are provided. The stop switches 42 to 44 are arranged directly below the display windows 26L, 26M, 26R corresponding to the reels 32L, 32M, 32R to be stopped. That is, when the left stop switch 42 is operated, the rotation of the left reel 32L is stopped, and when the middle stop switch 43 is operated, the rotation of the middle reel 32M is stopped and the right stop switch 44 is operated. In that case, the rotation of the right reel 32R is stopped. The stop switches 42 to 44 constitute a stop operation means operated to stop the variable display of the symbol based on the rotation of the reels 32L, 32M, 32R. The stop switches 42 to 44 are in a state in which the stop operation can be performed when a predetermined time has elapsed from the start of rotation of the left reel 32L. A lamp (not shown) is provided inside the stop switches 42 to 44, and the lamp is lit and displayed when the stop operation is possible, and the lamp is turned off when the stop operation is not possible such as when the reel is stopped. It has become so.

A medal insertion slot 45 for inserting medals is provided on the lower right side of the display windows 26L, 26M, and 26R. The medal slot 45 constitutes an input means for inputting a game medium. Further, paying attention to the fact that the medal insertion slot 45 is accompanied by an operation of directly inserting medals by the player, it can be said that it constitutes a direct input means for directly inputting the game medium.

The medals inserted from the medal insertion slot 45 are guided to either the storage passage 47 or the discharge passage 48 by the selector 46 as a passage switching means provided on the back surface of the front door 12. More specifically, the selector 46 is provided with a medal passage switching solenoid 46a, and the medal is guided to the discharge passage 48 side when the medal passage switching solenoid 46a is not excited, and the medal is guided to the discharge passage 48 side when the medal passage switching solenoid 46a is excited. Is guided to the storage passage 47 side. The medal guided to the storage passage 47 is guided to the hopper device 51 housed inside the housing 11. On the other hand, the medal guided to the discharge passage 48 is guided to the medal tray 50 from the medal discharge port 49 provided in the lower front portion of the front door 12, and is returned to the player.

The hopper device 51 includes a storage tank 52 for storing medals and a payout device 53 for paying out medals to the player. The payout device 53 discharges medals to the opening 48a provided in the discharge passage 48 by rotating a rotating plate for medal payout (not shown), and pays out medals to the medal tray 50 through the discharge passage 48. It has become. Further, on the right side of the hopper device 51, a spare tank 54 is provided to prevent medals exceeding a predetermined amount from being stored in the storage tank 52. Inside the storage tank 52 of the hopper device 51, a guide plate 52a for discharging medals from the storage tank 52 to the spare tank 54 is provided. Therefore, when medals are stored above the height at which the guide plate 52a is provided, the medals are stored in the spare tank 54.

A button-shaped return switch 55 is provided below the medal slot 45. When the return switch 55 is operated in a situation where the medals inserted into the medal insertion slot 45 are jammed in the selector 46, the selector 46 is mechanically interlocked and the medals packed in the selector 46 are medals. It is designed to be returned from the discharge port 49.

On the lower left side of the display windows 26L, 26M, 26R, a first credit insertion switch 56 for inserting three credited virtual medals as a game medium at a time is provided. Further, a second credit insertion switch 57 and a third credit insertion switch 58 are provided on the left side of the first credit insertion switch 56. The second credit insertion switch 57 is for inserting two virtual medals at a time, and the third credit insertion switch 58 is for inserting one virtual medal. Each of the credit insertion switches 56 to 58 constitutes an input means for inputting a game medium together with the medal insertion slot 45. Also, note that while the medal insertion slot 45 involves the operation of directly inserting medals by the player, each credit insertion switch 56 to 58 only involves the operation of inserting a virtual medal based on the stored memory. For example, it can be said that it constitutes an indirect input means for indirectly inputting a game medium. A lamp (not shown) is provided inside each of the credit insertion switches 56 to 58, and the lamp is lit and displayed when the insertion operation is possible, and the lamp is turned off when the insertion operation is not possible. ..

A checkout switch 59 is provided on the left side of the start lever 41. That is, the slot machine 10 has a credit function of storing and storing surplus inserted medals and payout medals at the time of winning as virtual medals until the predetermined maximum value (50 medals) is reached. When the settlement switch 59 is operated in the stored and stored state, the virtual medal is paid out from the medal outlet 49 as a real medal. In this case, paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the settlement switch 59 constitutes a settlement operation means for actually paying out the stored and stored game medium.

Below the display windows 26L, 26M, 26R of the game panel 25, there is a credit display unit 60 that displays the number of virtual medals that are credited, and the number of remaining medals that display the number of medals remaining to be paid out by the end of the BB state. A display unit 61 and a payout number display unit 62 for displaying the number of medals paid out at the time of winning are provided, respectively. These display units 60 to 62 are composed of a 7-segment display, but it is naturally possible to replace them with a liquid crystal display or the like.

Here, the relationship between the number of bets on medals and the combination line to be activated will be described with reference to FIG. 7. When a medal is inserted from the medal slot 45 at the start of the game, a bet is placed.

When the first medal is inserted into the medal slot 45, the number of bets becomes 1, and the middle line L2 is activated. When the second medal is inserted into the medal slot 45, the number of bets is 2, and a total of 3 combination lines including the upper line L1 and the lower line L3 in addition to the middle line L2 are activated. When the third medal is inserted into the medal insertion slot 45, the number of bets is 3, and all of the combination lines L1 to L5 are activated.

When four or more medals are inserted into the medal slot 45, if the number of virtual medals stored and stored at that time is less than 50, the surplus medals exceeding three are stored inside the slot machine 10. , The number of virtual medals of the credit display unit 60 is additionally displayed. On the other hand, when the number of virtual medals is 50 or reaches 50, the selector 46 switches from the storage passage 47 to the discharge passage 48, and the surplus medals are returned from the medal discharge port 49 to the medal tray 50. Will be done.

Further, the virtual medals are stored and stored, and even when any of the first to third credit insertion switches 56 to 58 is operated at the start of the game, the virtual medals are inserted and a bet is made. When any of the first to third credit insertion switches 56 to 58 is operated, the number of virtual medals displayed on the credit display unit 60 is subtracted by the number of inserted virtual medals. Except for the above, since it is the same as the case where the medal is inserted from the medal insertion slot 45, the description thereof will be omitted.

By the way, when the virtual medal to be inserted when any of the first to third credit insertion switches 56 to 58 is operated is not stored and stored, for example, when the display of the credit display unit 60 is 2, the first When the credit insertion switch 56 is operated or the like, all the numerical values of the credit display unit 60 are subtracted to 0, and only the virtual medals that can be inserted are bet.

On the upper part of the front door 12, there is an upper lamp 63 that lights up or blinks as the game progresses, and a pair of left and right lamps that sound various sound effects as the game progresses and notify the player of the game state. The speaker 64 and an auxiliary display unit 65 for giving various information to the player are provided. The auxiliary display unit 65 is for executing various display effects as the game progresses, and the game by each reel 32L, 32M, 32R can be considered to be due to the main display unit. Therefore, in the present embodiment, the auxiliary display unit 65 is used. It is called an auxiliary display unit 65. On the back surface of the auxiliary display unit 65, an upper lamp 63, a speaker 64, and a display control device 81 for driving the auxiliary display unit 65 are provided.

A power supply box 70 is provided on the left side of the hopper device 51 inside the housing 11. The power supply box 70 houses the power supply device 91 inside, and also includes a power supply switch 71, a reset switch 72, a setting key insertion hole 73, and the like. The power switch 71 is a start switch for supplying power to each part including the main control device 101. The reset switch 72 is a switch for resetting the error state of the slot machine 10. Further, the setting key insertion hole 73 is for a hole manager or the like to adjust the output of medals. That is, the winning probability of the slot machine 10 can be set by the hall manager or the like inserting the setting key into the setting key insertion hole 73 and operating the ON operation. The reset switch 72 is operated not only when resetting the error state but also when changing the winning probability of the slot machine 10.

Above the reel unit 31, a main control device 101 that controls and manages the game is attached to the housing 11.

Next, the electrical configuration of the slot machine 10 will be described with reference to the block diagram of FIG.

The main control device 101 is equipped with a microcomputer centered on the CPU 102, which is an arithmetic processing means. In addition to the power supply device 91, the CPU 102 includes a first clock circuit 103 that outputs a rectangular wave (first clock signal) having a predetermined frequency of 8,000 MHz, and an input / output port 104 (specifically, a connector and a driver IC). , An input / output port composed of a chip select IC, etc.), a basic random number generator 150 for generating a basic random number, and the like are connected via an internal bus. The main control device 101 functions as a main board built in the slot machine 10.

On the input side of the main controller 101, there is a reel unit 31 (more specifically, a reel index sensor that individually detects that each reel 32L, 32M, 32R has made one rotation), and a start detection sensor that detects the operation of the start lever 41. 41a, stop detection sensors 42a to 44a for individually detecting the operation of each stop switch 42 to 44, insertion medal detection sensor 45a for detecting medals inserted from the medal insertion port 45, and medals to be paid out from the hopper device 51. Payout detection sensor 51a, credit insertion detection sensor 56a to 58a that individually detects the operation of each credit insertion switch 56 to 58, settlement detection sensor 59a that detects the operation of the settlement switch 59, and reset detection that detects the operation of the reset switch 72. Various sensors such as the sensor 72a and the setting key detection sensor 73a that detects that the setting key is inserted into the setting key insertion hole 73 and the ON operation is performed are connected, and the signals from these various sensors pass through the input / output port 104. It is designed to be output to the CPU 102 via.

The inserted medal detection sensor 45a is actually composed of a plurality of sensors. That is, the storage passage 47 from the medal insertion slot 45 to the hopper device 51 is formed so that medals can pass in one row. Then, the storage passage 47 is provided with the first sensor, and the second sensor and the third sensor are close to each other on the downstream side separated by the width of the medal or more (at least for a certain period of time, the same medal is detected at the same time). It is provided in close proximity to each other. The inserted medal detection sensor 45a is composed of these first to third sensors. The main control device 101 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, it considers that the medal is jammed or fraudulent, and sets an error state. When an error state occurs, the error state is notified and the operation by the player is invalidated until the error state is cleared. The main control device 101 also monitors the order in which the second sensor and the third sensor are turned on and off. Specifically, the second and third sensors are both off, only the second sensor is on, the second and third sensors are both on, the third sensor is on, and the second and third sensors are both off. It is determined that the medals have been normally captured only when the medals have become, and the time for shifting to each on / off switching is within the predetermined time, and in other cases, an error state is set. This is done in order to prevent medals from being clogged in the storage passage 47 and to prevent fraud in which medals are reciprocated in the vicinity of the inserted medal detection sensor 45a to be mistaken for inserted medals.

Further, a power supply device 91 is connected to the input side of the main control device 101 via an input / output port 104. The power supply device 91 is equipped with a power supply unit 91a that supplies drive power to each electronic device of the slot machine 10 including the main control device 101, a power failure monitoring circuit 91b, and the like.

The power failure monitoring circuit 91b monitors the power cutoff state and generates a power failure signal not only when the power is cut off but also when the power supply is cut off by the power switch 71. Therefore, the power failure monitoring circuit 91b monitors the stabilized drive voltage of DC 12 volt in this example output from the power supply unit 91a, and determines that the power supply is cut off when this drive voltage drops to less than 10 volt, for example. It is configured to output a power failure signal. The power failure signal is supplied to each of the CPU 102 and the input / output port 104, and the CPU 102 recognizes the power failure signal to execute the power failure processing described later. Further, the power failure signal is also configured to be supplied to the display control device 81.

The power supply unit 91a is configured to output a regulated voltage of 5 volts, which is used as a drive voltage in a control system such as the main control device 101, even when the output voltage drops to less than 10 volts. As the time for outputting this regulated voltage, a sufficient time is secured for executing the power failure processing by the main control device 101.

There is. Although not shown, lamps provided inside the stop switches 42 to 44, lamps provided inside the credit input switches 56 to 58, and the like are also input and output on the output side of the main control device 101. It is connected via port 104.

The display control device 81 is a control device for driving the upper lamp 63, the speaker 64, and the auxiliary display unit 65, and includes a substrate in which a CPU, ROM, RAM, and the like for driving these are integrated. Then, after receiving the signal from the main control device 101, the display control device 81 independently drives and controls the upper lamp 63, the speaker 64, and the auxiliary display unit 65. Therefore, the display control device 81 is a sub-base that executes auxiliary control in relation to the main control device 101, which is the main base that controls and manages the game. The various display units 60 to 62 may also be configured to be driven and controlled by the display control device 81.

The CPU 102 described above is a one-chip CPU, and a ROM 105 that stores various control programs and fixed value data executed by the CPU 102 and various data that are temporarily executed when executing the control program stored in the ROM 105 are temporarily stored. In addition to the RAM 106 for securing a work area for storing data, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit are built-in as is well known, although not shown. There is. A main memory as a storage means is configured by the ROM 105 and the RAM 106, and a program for executing various processes shown in the flowcharts shown in FIGS. 12 and 12 is stored in the ROM 105 described above as a part of the control program.

As shown in FIG. 10, the RAM 106 includes a winning flag storage area 106a for storing the lottery result of the winning combination, and a sliding table for storing a sliding table used when stopping control of each reel 32L, 32M, 32R. In addition to the storage area 106b and the state information storage area 106c for storing the game state such as the BB state, the random number storage area 110 for storing the random numbers used when drawing the winning combination has a function as various counters. Various areas such as a counter area 111 and a sensor information storage area 112 for storing the signal input status from the various sensors described above are secured. The counter area 111 includes a first counter 111a and a second counter 111b used when creating a random number, an update counter 111c used in interrupt waiting processing described later, a delay counter 111d for determining an acquisition timing of a basic random number, and the number of credits. It is composed of a credit counter (not shown) or the like for storing. The sensor information storage area 112 includes a reel index detection area, a start detection area, a left stop detection area, a middle stop detection area, a right stop detection area, a inserted medal detection area, a payout detection area, and a first credit. It is composed of an input detection area, a second credit input detection area, a third credit input detection area, a settlement detection area, a reset detection area, a setting key detection area, and the like. Each of these detection areas can store the history of the presence / absence of signal input from the corresponding detection sensor, and has three storage areas: a first area 112a, a second area 112b, and a third area 112c. It is composed of. Each detection area has a 1-byte structure, and the lower 3 bits are associated with each of the above storage areas. More specifically, it is associated with the first area 112a, the second area 112b, and the third area 112c in order from the lower bits.

Further, the RAM 106 has a configuration in which a backup voltage is supplied from the power supply device 91 to hold (back up) data even after the power supply of the slot machine 10 is cut off, and the RAM 106 holds the data. Backup area is provided. The backup area is an area for storing the value of the stack pointer when the power is cut off due to a power failure or the like (including power cutoff by operating the power switch 71. The same applies hereinafter). Yes, when the power failure is resolved (including turning on the power by operating the power switch 71, the same applies hereinafter), the state of the slot machine 10 can be restored to the state before the power was cut off based on the information in the backup area. .. Writing to the backup area is executed when the power is cut off by a power failure process (see FIG. 12), and restoration of each value written in the backup area is executed in the main process (see FIG. 14) when the power is turned on.

Returning to the description of FIG. 9, the NMI terminal (non-maskable interrupt terminal) of the CPU 102 is configured to input a power failure signal from the power failure monitoring circuit 91b when the power is cut off due to the occurrence of a power failure or the like. Then, when the power is cut off, the NMI interrupt process as the power failure flag generation process is immediately executed.

Here, the connection relationship between the basic random number generator 150, the start detection sensor 41a, and the CPU 102 will be described in more detail based on the block diagram of FIG.

A second clock circuit 151 that outputs a rectangular wave (second clock signal) having a predetermined frequency of 7.915 MHz and a CPU 102 are connected to the input side of the basic random number generator 150. The CPU 102 is connected to the output side of the basic random number generator 150.

The basic random number generator 150 is hardware having a counter 150a and a latch circuit 150b. The counter 150a is a 16-bit free-run counter, and is configured to be incremented by 1 in order within the range of 0 to 65535 and to return to 0 after reaching the maximum value (that is, 65535). A second clock circuit 151 is connected to the counter 150a, and when the second clock signal from the second clock circuit 151 is input, the count value of the counter 150a is updated. The latch circuit 150b is configured by combining a plurality of D flip-flop circuits so that the count value of the counter 150a can be latched (held). A CPU 102 is connected to the latch circuit 150b, and when a latch signal from the CPU 102 is input, the count value of the counter 150a at that timing is latched by the latch circuit 150b. Then, the latched count value is output as a basic random number to the input port built in the CPU 102.

A monitoring circuit 152 for monitoring the second clock circuit 151 is connected to the CPU 102. The monitoring circuit 152 is composed of a D flip-flop circuit. That is, the monitoring circuit 152 has a data terminal (D terminal) and a clock terminal (CLK terminal) as input terminals, and has a positive logic output terminal (Q terminal) and a negative logic output terminal (Q bar terminal) as output terminals. doing. The start detection sensor 41a is connected to the D terminal via the waveform shaping circuit 153 and the input / output port 104, and the second clock circuit 151 is connected to the CLK terminal via the reversing device 154. Further, the Q terminal is not connected, and the Q bar terminal is connected to the input port built in the CPU 102.

The start detection sensor 41a outputs an operation signal when the start lever 41 is operated. More specifically, the start detection sensor 41a outputs an operation signal when the start lever 41 moves from the initial position, and stops outputting the operation signal when the start lever 41 returns to the initial position. The waveform shaping circuit 153 is composed of a Schmitt trigger circuit. A threshold value is set in the waveform shaping circuit 153, and the waveform shaping circuit 153 sends a detection signal to the monitoring circuit 152 when the operation signal output from the start detection sensor 41a becomes larger than the voltage rise side threshold value. It outputs and stops the output of the detection signal when the operation signal becomes smaller than the voltage drop side threshold. That is, the waveform shaping circuit 153 is a circuit for shaping the bluntness (rising delay and falling delay) of the operation signal output from the start detection sensor 41a. The waveform shaping circuit 153 may be connected between the input / output port 104 and the monitoring circuit 152, and the waveform shaping circuit 153 can be provided on the main control device 101.

The monitoring circuit 152 receives an operation signal (more specifically, from the waveform shaping circuit 153) at the timing when the inverted second clock signal (inverted clock signal) is input to the CLK terminal (more specifically, the timing at which the inverted clock signal rises). When the detection signal) is input, the start signal is output to the CPU 102. The start signal is continuously output until the operation signal is not input at the timing when the inverted clock signal is input to the CLK terminal. In other words, it can be said that the monitoring circuit 152 holds the input state of the operation signal until the inverting clock signal is input to the CLK terminal.

In addition to the Q-bar terminal of the monitoring circuit 152, the latch circuit 150b of the basic random number generator 150 and the first clock circuit 103 that outputs the first clock signal are connected to the input side of the CPU 102. Further, a latch circuit 150b of the basic random number generator 150 is connected to the output side of the CPU 102. The first clock circuit 103 outputs a rectangular wave having a predetermined frequency of 8,000 MHz, and is configured so as not to be synchronized with the second clock circuit 151. The CPU 102 is designed to perform various operations when the first clock signal is input. For example, it is determined whether or not the start signal is input based on the input of the first clock signal, and the latch signal is output to the basic random number generator 150 based on the input of the start signal. Then, the count value output from the basic random number generator 150 is acquired as the basic random number. Explaining in more detail whether or not the start signal is input, the CPU 102 is connected to the Q bar terminal of the monitoring circuit 152, so that the input signal from the Q bar terminal is switched from the H level to the L level. It is determined that the start signal has been input to.

Subsequently, each control process executed by the CPU 102 of the main control device 101 will be described. The CPU 102 performs various processes based on the input of the first clock signal from the first clock circuit 103. The processing of the CPU 102 is roughly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (at a cycle of 1.49 msec in this embodiment), and a power failure signal to the NMI terminal. There is an NMI interrupt process that is activated in response to the input of. In the following, for convenience of explanation, the timer interrupt processing will be described first, and then the main processing will be described.

FIG. 12 is a flowchart of timer interrupt processing that is periodically executed by the main control device 101, and a timer interrupt is generated by the CPU 102 of the main control device 101, for example, every 1.49 msec.

First, in the register save process shown in step S101, the values of all the registers in the CPU 102 used in the normal process described later are saved in the backup area of the RAM 106. In step S102, it is confirmed whether or not the power failure flag is set, and if the power failure flag is set, the process proceeds to step S103 to execute the power failure processing.

Here, the outline of the power failure processing will be described.

When the power supply is cut off due to the occurrence of a power failure or the like, a power failure signal is output from the power failure monitoring circuit 91b of the power supply device 91, and the power failure signal is input to the main control device 101 via the NMI terminal. When a power failure signal is input, the main control device 101 immediately executes NMI interrupt processing and sets the power failure flag in the power failure flag storage area provided in the RAM 106.

In the power failure processing, it is first determined whether or not the command transmission is completed, and if the transmission is not completed, this processing is terminated and the timer interrupt processing is restored to end the command transmission. When the command transmission is completed, the value of the stack pointer of the CPU 102 is saved in the backup area of the RAM 106. After that, the output state of the output port in the input / output port 104 is cleared, and all actuators (not shown) are turned off. Then, when the power failure is resolved, the RAM determination value for determining whether the data in the RAM 106 is normal is calculated and stored in the backup area. The RAM determination value is specifically the two's complement of the checksum at the work area address of the RAM 106. By saving the RAM determination value in the backup area, the checksum of the RAM 106 becomes 0. By setting the checksum of the RAM 106 to 0, subsequent RAM access is prohibited. After performing the above processing, an infinite loop is entered in case the power supply is completely cut off and the processing cannot be executed. In consideration of the case where the power failure flag is erroneously set due to noise or the like, it is confirmed whether or not the power failure signal is output until the infinite loop is entered. If the power failure signal is not output, the power failure state has been restored. Therefore, writing to the RAM 106 is permitted, the power failure flag is reset, and the timer interrupt processing is restored. If the power failure signal is continuously output, it goes into an infinite loop as it is. By the way, it is confirmed whether or not the power failure signal is output even under the infinite loop, and if the power failure signal is no longer output, the process shifts to the main process.

Returning to the description of the timer interrupt process, if the power failure flag is not set in step S102, various processes after step S104 are performed.

That is, in step S104, the watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S105, an interrupt end declaration process is performed so that the next timer interrupt can be set for the CPU 102 itself. In step S106, in order to rotate each reel 32L, 32M, 32R, a stepping motor control process for driving a stepping motor, which is a rotating cylinder drive motor, is performed. In step S107, a sensor monitoring process is performed to read the states of various sensors (see FIG. 9) such as the stop detection sensors 42a to 44a, the insertion medal detection sensor 45a, and the payout detection sensor 51a connected to the input / output port 104.

Here, the sensor monitoring process will be described with reference to the flowchart of FIG. First, in step S151, the sensor information transfer process is performed. In the sensor information transfer process, the data stored in the first to third areas 112a to 112c of the detection area to be confirmed this time are sequentially shifted to the upper area side. For example, when reading the state of the reset detection sensor 72a, in the reset detection area, the data in the third area 112c is first cleared, and then the second area → the third area, the first area → the second area, and so on. Shift the data in each area to. In the following step S152, the signal input state is read by referring to the connected port of the sensor to be confirmed this time. In step S153, it is determined whether or not an ON signal is input. When the ON signal is input, "1" is set in the first area 112a of the corresponding detection area in step S154, and when the ON signal is not input, the corresponding detection area is set in step S155. “0” is set in the first area 112a of the detection area. After that, in step S156, it is determined whether or not the states of all the sensors have been confirmed. When the status of all the sensors is confirmed, the present process is terminated as it is, and when the status is not confirmed, the process returns to step S151 to confirm the status of the unconfirmed sensor. As described above, in the sensor monitoring process, for various sensors connected to the input / output port 104, a process of storing "0" or "1" in the first area 112a of the corresponding detection area is executed. When reading the state of the start detection sensor 41a, in step S153, it is determined that the ON signal is input when the L level signal is input, and ON when the H level signal is input. It is determined that no signal has been input.

Returning to the description of the timer interrupt process, in step S108, a timer calculation process for subtracting the values of each counter and the timer is performed. In step S109, the value of the update counter 111c is updated by 1. In step S110, a process is performed in which the number of bets on medals and the result of counting the number of payouts are output to the external centralized terminal board 121. In step S111, a command output process for transmitting various commands such as a lottery result command, which will be described later, to the display control device 81 is performed. In step S112, a segment data setting process for setting segment data to be displayed on the credit display unit 60, the remaining payout number display unit 61, and the payout number display unit 62 is performed. In step S113, the segment data display process of supplying the segment data set in the segment data setting process to the display units 60 to 62 and displaying the corresponding numbers, symbols, and the like is performed. In step S114, a port output process for outputting data corresponding to the I / O device from the input / output port 104 is performed. In step S115, the values of the registers saved in the backup area in the previous step S101 are returned to the corresponding registers in the CPU 102. In step S116, the value of the first counter 111a for generating the basic random number is updated by 1. The first counter 111a is a 16-bit storage area formed in the RAM 106, and can generate a basic random number of 0 to 65535. In step S117, a delay counter process is performed in which the value of the delay counter 111d is added or subtracted. After that, in step S118, the next timer interrupt is permitted, and this series of timer interrupt processing is terminated.

FIG. 14 is a flowchart showing a main process in the main control device 101 executed after the power is turned on. The main process is executed when the power is turned on by recovering from a power failure or turning on the power switch 71.

First, in step S201, as the initialization process, the value of the stack pointer is set in the CPU 101, the interrupt mode for enabling the interrupt process is set, and then various settings for the register group in the CPU 101, the I / O device, and the like are set. And so on. When these initialization processes are completed, in step S202, it is determined whether or not the setting key is inserted into the setting key insertion hole 73 and the ON operation is performed. Specifically, the operation determination process shown in FIG. 15 is performed.

In the operation determination process, first, in step S251, it is determined whether or not the determination target of this time is the reset switch 72, and in step S252, the determination target of this time is any of the first to third credit insertion switches 56 to 58. Determine if it exists. When the determination target this time is any of the reset switch 72 and the first to third credit insertion switches 56 to 58, the all area reference processing shown in steps S253 to S256 is performed. On the other hand, when the determination target this time is other than the above switches, specifically, when any of the start lever 41, the stop switches 42 to 44, the clearing switch 59, and the setting key, steps S257 to S260 Performs the 1-area reference process shown in.

In the all area reference process, in step S253, the first to third areas 112a to 112c of the sensor information storage area 112 corresponding to the determination target this time are referred to. In step S254, it is determined whether or not the reference result is "011", that is, whether or not "1" is stored in the first area, "1" is stored in the second area, and "0" is stored in the third area. To do. If the reference result is "011", it is determined in step S255 that the current determination target has been operated, and this process ends. On the other hand, if the reference result is not "011", it is determined in step S256 that the current determination target has not been operated, and this process ends. That is, in the all area reference processing, it is determined whether or not the determination target has been operated based on the history of the presence / absence of signal input from the corresponding detection sensor.

In the one-area reference process, in step S257, only the first area 112a of the sensor information storage area 112 corresponding to the determination target this time is referred to. In step S258, it is determined whether or not the reference result is "1", that is, whether or not "1" is stored in the first area. If the reference result is "1", it is determined in step S259 that the current determination target has been operated, and this process ends. On the other hand, when the reference result is "0", it is determined in step S260 that the current determination target has not been operated, and this process ends. That is, in the one-area reference process, it is determined whether or not the determination target has been operated based on the latest information on the presence or absence of signal input from the corresponding detection sensor.

Returning to the description of the main process, in step S202, since the determination target is the setting key, one area reference process is performed. That is, referring to the first area 112a of the setting key detection area, when "1" is stored, it is determined that the setting key is ON, and when "0" is stored, it is determined that the setting key is ON. Determines that the setting key has not been turned on. If the setting key is turned on, the process proceeds to step S203 to perform a forced RAM clear process. In the forced RAM clear process, all the data other than the data (count value) stored in the first counter 111a, the second counter 111b, and the delay counter 111d among the data stored in the RAM 106 is cleared. That is, the values of the first counter 111a, the second counter 111b, and the delay counter 111d are not cleared (initialized) even when the RAM is cleared. The values of the first counter 111a, the second counter 111b, and the delay counter 111d are not cleared (initialized) even when the reset switch 72 is operated to recover from the error state.

In step S204, the winning probability setting process is performed. Here, the winning probability setting process will be described with reference to FIG. The slot machine 10 is prepared in advance with six stages of winning probabilities from "setting 1" to "setting 6", and the winning probability setting process sets which winning probability the internal process is to be executed based on. It is a process to do.

In step S301, the next timer interrupt is permitted. After that, the current set value is read in step S302, and the current set value is displayed on the credit display unit 60 in step S303. However, in the process immediately after the setting key is inserted and the ON operation is performed, the data of the RAM 106 is cleared by the previous forced RAM clear process, so the set value displayed on the credit display unit 60 is "1". is there.

In step S304, interrupt wait processing is performed.

In the interrupt waiting process, as shown in the flowchart of FIG. 17, register save processing is performed in step S401. In step S402, the next timer interrupt is permitted and the current value of the update counter 111c is acquired. In steps S403 to S407, the counter update process is performed. In the counter update process, first, the next timer interrupt is prohibited in step S403, then the value of the delay counter 111d is updated by 1 in step S404, and the value of the second counter 111b is updated by 1 in step S405. The delay counter 111d is a 4-bit storage area formed in the RAM 106, and can generate a count value of 0 to 16. Like the first counter 111a, the second counter 111b is a 16-bit storage area formed in the RAM 106, and can generate basic random numbers of 0 to 65535. After updating the delay counter 111d and the second counter 111b, in step S406, the next timer interrupt is permitted, and in step S407, it is determined whether or not the value of the update counter 111c has changed. Specifically, it is determined whether or not the value acquired in step S402 and the value of the update counter 111c match. As described above, the value of the update counter 111c is updated in step S109 of the timer interrupt process. Therefore, when the value of the update counter 111c has not changed, it means that the timer interrupt processing has not been performed since the processing of step S402 was performed. In such a case, the process returns to step S403 and the counter update process is performed. On the other hand, when the value of the update counter 111c changes, it means that the timer interrupt process has been performed. Therefore, the register return process is performed in step S408 to end this process.

When the interrupt waiting process is completed, it is determined in step S305 whether or not the start lever 41 has been operated. Specifically, as such a determination process, one area reference process of the above-mentioned operation determination process is performed. That is, with reference to the first area 112a of the start detection area, it is determined that the start lever 41 has been operated when "1" is stored, and when "0" is stored, the start lever 41 is stored. Is not operated. When the start lever 41 is not operated, the setting update process shown in steps S306 to S308 is performed. In step S306, the interrupt waiting process described above is performed, and in step S307, it is determined whether or not the reset switch 72 has been operated. More specifically, all area reference processing of the operation determination processing is performed. That is, all areas 112a to 112c of the reset detection area are referred to, and if "011" is stored, it is determined that the reset switch 72 has been operated, and if "011" is not stored, the reset switch is switched. It is determined that 72 is not operated. If the reset switch 72 is not operated, the process returns to step S303 as it is, and if the reset switch 72 is operated, the set value is updated by 1 in step S308 and then returned to step S303. That is, in the setting update process, the set value is updated by 1 each time it is determined that the reset switch 72 has been operated, and the updated set value is displayed on the credit display unit 60. If the reset switch 72 is operated when the set value is "6", the set value is updated to "1".

When the start lever 41 is operated in step S305, after performing interrupt waiting processing in step S309, it is determined in step S310 whether or not the ON operation of the setting key is continuously performed. If the ON operation of the setting key is continuously performed, the process returns to step S309, and if the ON operation is completed, the next timer interrupt is prohibited in step S311. After that, in step S312, the set value is saved, and in step S313, among the data stored in the RAM 106, the data other than the set value, the value of the first counter 111a, the second counter 111b, and the value of the delay counter 111d are cleared. This process ends.

Returning to the description of the main process, after the winning probability setting process is performed in step S204, the normal process for performing the main control related to the game is executed in step S205.

On the other hand, if the setting key is not turned on in step S202, the power recovery process shown in step S206 and subsequent steps is performed. The power recovery process is a process of returning the state of the slot machine 10 to the state before the power is cut off. Therefore, in the power recovery process, it is first necessary to confirm whether the data in the RAM 106 is normal.

Therefore, in step S206, it is determined whether or not the set value is normal. Specifically, when the set value is any of 1 to 6, it is determined to be normal, and when it is 0 or 7 or more, it is determined to be abnormal. If the set value is normal, it is confirmed in step S207 whether or not the power failure flag is set. If the power failure flag is set, it is further confirmed in step S208 whether or not the RAM determination value is normal. Specifically, the checksum value of the RAM 106 is checked, and it is confirmed whether or not the value is normal, that is, whether or not the checksum value including the RAM determination value is 0. When the checksum value including the RAM determination value is 0, it is determined that the data in the RAM 106 is normal.

If it is determined in step S208 that the RAM determination value is normal, the process proceeds to step S209, the value of the stack pointer saved in the backup area is written to the stack pointer of the CPU 102, and the stack state is before the power is cut off. Return to the state. Next, in step S210, a power recovery command for notifying the execution of the power recovery process is transmitted to the display control device 81. After that, in step S211, the game is stopped and the automatic settlement setting is saved, and in step S212, various sensors such as the start detection sensor 41a are initialized. After the above processing is completed, the power failure flag is reset in step S213, and the address returns to the address before the power was cut off. Specifically, the timer interrupt processing described above is restored, and the watchdog timer clear processing (step S104) is executed.

On the other hand, if any of steps S206 to S208 is NO, that is, the set value is abnormal, the power failure flag that should be set when the power is cut off is not set, or the RAM determination value is abnormal. There is a high possibility that the data in RAM 106 has been destroyed. In such a case, the operation prohibition process shown in steps S214 to S216 is performed. As the operation prohibition process, first, the next timer interrupt process is prohibited in step S214, and in step S215, all the output ports in the input / output port 104 are cleared, so that all the actuators connected to the input / output port 104 are removed. Control to off state. After that, in step S216, an error notification process for notifying the hall manager or the like of the occurrence of an error is performed using the upper lamp 63 or the like. Such an operation prohibited state is maintained until the above-mentioned winning probability setting process is performed.

Next, a normal process for performing main control related to the game will be described with reference to the flowchart of FIG.

First, in step S501, the next timer interrupt is permitted. In step S502, pre-start processing is performed to enable the game. In the pre-start process, the display control device 81 or the like waits until the initialization is completed. When the initialization of the display control device 81 or the like is completed, the game management process shown in steps S503 to S508 is performed.

As a game management process, in step S503, data such as various game information stored in the RAM 106 (for example, a random number value used in the previous game) is cleared. After that, in step S504, the start waiting process is performed.

Here, the start waiting process will be described with reference to the flowchart of FIG.

In step S601, it is determined whether or not the re-game winning is established in the previous game. If the re-game winning is established, the automatic input process is performed in step S602. The automatic insertion process is a process for automatically inserting the same number of virtual medals as the previous number of bets. In the automatic insertion process, virtual medals are inserted without reducing the number of virtual medals displayed on the credit display unit 60. That is, if the re-game prize is established in the previous game, the player can play the current game without reducing the number of medals owned and without inserting medals. If the re-game winning is established in the previous game, the same number as the number of bets is first added and displayed on the credit display unit 60, and the virtual medal is inserted after the number of added displays is reduced in the automatic insertion process. It may be configured to perform. If it is determined in step S601 that the re-game winning has not been established, the medal acceptance permission process for permitting the bet of the medal is performed in step S603. In the medal acceptance permission process, the medal passage switching solenoid 46a is switched to the excited state so that the medal can be inserted. After that, the pre-start preparatory processing shown in steps S604 to S620 is repeated until a start command for starting the game is generated.

As a pre-start preparatory process, first, in step S604, an abnormality confirmation process is performed to confirm whether or not an abnormality has occurred in the sensor reading result performed in the sensor monitoring process step S107 of the timer interrupt process. In the abnormality confirmation process, when it is determined that an error has occurred, the slot machine 10 is put into an error state and an error occurrence process for notifying the occurrence of the error is performed. Such an error state is maintained until the reset switch 72 is operated. If the reading result of the sensor is normal, the process proceeds to step S605 to perform interrupt waiting processing. In step S606, it is determined whether or not any of the clearing switch 59 and the credit insertion switches 56 to 58 has been operated.

Specifically, the clearing switch 59 is subjected to one area reference processing of the operation determination processing, and the credit insertion switches 56 to 58 are subjected to the entire area reference processing of the operation determination processing. That is, with reference to the first area 112a of the clearing detection area, it is determined that the clearing switch 59 has been operated when "1" is stored, and when "0" is stored, the clearing switch 59 is stored. Is not operated. When the clearing switch 59 is not operated, all areas 112a to 112c of the first credit insertion detection area are referred to, and when "011" is stored, the first credit insertion switch 56 is operated. If "011" is not stored, it is determined that the first credit insertion switch 56 is not operated. When the first credit insertion switch 56 is not operated, all areas 112a to 112c of the second credit insertion detection area are referred to, and when "011" is stored, the second credit insertion switch 57 is set. It is determined that the operation has been performed, and if "011" is not stored, it is determined that the second credit insertion switch 57 has not been operated. When the second credit insertion switch 57 is not operated, all areas 112a to 112c of the third credit insertion detection area are referred to, and when "011" is stored, the third credit insertion switch 58 is set. It is determined that the operation has been performed, and if "011" is not stored, it is determined that the third credit insertion switch 58 has not been operated.

When any of the switches 56 to 59 is operated, or when the automatic insertion process is performed in step S602, the process proceeds to step S607 and the number of medals to be paid out displayed on the payout number display unit 62 is cleared. .. After that, or when neither the clearing switch 59 nor the credit insertion switches 56 to 58 is operated, the value of the second counter 111b is updated by 1 in step S608, and the delay counter 111d is updated in step S609. Update the value by 1. In the following step S610, the medal return process is performed. In the medal return process, when it is determined in step S606 that the clearing switch 59 has been operated, the same number of medals as the credited virtual medals are paid out.

In step S611, whether or not the medal can be bet is determined based on the state of the medal passage switching solenoid 46a, that is, the excited state or the non-excited state. Then, when the bet is possible, the process proceeds to step S613 after performing the credit insertion process in step S612. In the credit insertion process, when it is determined in step S606 that any of the credit insertion switches 56 to 58 has been operated, the number of virtual medals displayed on the credit display unit 60 is subtracted and displayed, or an effective line is set. Performs processing related to the insertion of virtual medals such as subtraction. If the bet is not possible, the process proceeds to step S613 as it is without performing the credit insertion process. Incidentally, as a typical example of a state in which betting is not possible, a case where a re-game winning is established in the previous game and the automatic insertion process is performed in step S602 can be mentioned. In step S613, the input determination process is performed. In the insertion determination process, it is determined whether or not a medal has been inserted based on the detection signal from the insertion medal detection sensor 45a, and if a medal has been inserted, processing such as setting an effective line is performed.

In step S614, it is determined whether or not the bet has been made, and if not bet, the setting display process is performed in step S615. In the setting display process, it is determined whether or not the setting key is inserted into the setting key insertion hole 73 and the ON operation is performed. If the setting key is ON, the current set value is set to the credit display unit 60. Perform the process to be displayed in. In step S616, it is determined whether or not the demonstration effect has been started. The slot machine 10 is configured to perform a demonstration effect on the auxiliary display unit 65 or the like when a predetermined time (for example, 1 minute) has elapsed after clearing the game information of the RAM 106 in step S503. Therefore, in step S616, it is determined whether or not the predetermined time has elapsed, and if the predetermined time has elapsed, a demo start command for further starting the demo effect has been transmitted to the display control device 81. Determine if it exists. If the predetermined time has not elapsed, or if the demo start command has not been transmitted, the process returns to step S604 after performing the effect waiting process in step S617. In the effect waiting process, the counter for measuring the elapsed time after clearing the game information of the RAM 106 is updated, and when the predetermined time has elapsed, the demo start command is set. However, in the effect waiting process, the demo start command is only set in the ring buffer, and the command is not transmitted to the display control device 81. The command is transmitted to the display control device 81 by the command output process S111 of the timer interrupt process described above. If it is determined in step S616 that the demo start command has been transmitted, the process returns to step S604 as it is without performing the effect waiting process.

When it is determined in step S614 that the bet has been made, it is determined in step S618 whether or not the number of bets has reached the specified number (3 in the present embodiment), and the number of bets has reached the specified number. If not, the process returns to step S604. When the number of bets has reached the specified number, interrupt waiting processing is performed in step S619, and whether or not the start lever 41 is operated in step S620, that is, "1" is set in the first area 112a of the start detection area. Is set or not. If the start lever 41 is not operated, the process returns to step S604.

On the other hand, when the start lever 41 is operated, the game can be started when the start lever 41 is operated in a situation where a specified number of medals are bet, so the game is started in order to start the game. It means that a command has occurred. In such a case, the medal acceptance prohibition process is performed in step S621. In the medal acceptance prohibition process, the medal passage switching solenoid 46a is switched to the non-excited state, so that the medal cannot be inserted (bet). After that, a delay process is performed in step S622 to end this process.

In the delay processing, as shown in the flowchart of FIG. 20, the delay flag is set in step S631. Here, the delay flag is a flag for changing the update process of the delay counter 111d. Specifically, in the delay counter process S117 of the timer interrupt process, as shown in the flowchart of FIG. 21, it is determined in step S651 whether or not the delay flag is set. If the delay flag is not set, the value of the delay counter 111d is added by 1 in step S652, and this process ends. On the other hand, when the delay flag is set, the value of the delay counter 111d is subtracted by 1 in step S653, and this process ends. As described above, in the timer interrupt processing, when the delay flag is not set, the value of the delay counter 111d is periodically added by 1, and when the delay flag is set, the value of the delay counter 111d is periodically incremented by 1. Performs subtraction processing. Therefore, when the delay flag is set in step S631, the value of the delay counter 111d is periodically decremented by 1 in the subsequent timer interrupt processing. Therefore, in step S632, it is determined whether or not the value of the delay counter 111d has become 0, and if it is not 0, the process waits as it is. When the value of the delay counter 111d becomes 0, the process proceeds to step S633, and a latch signal is output to the basic random number generator 150. More specifically, in step S633, only the flag for outputting the latch signal is set, and the actual output of the latch signal is performed in the timer interrupt process. The latch signal is continuously output for one interrupt of the timer interrupt process (that is, 1.49 msec). After that, the delay flag is cleared in step S634, and this process ends.

As described above, when the latch signal from the CPU 102 is input, the basic random number generator 150 latches the count value of the counter 150a at that timing to the latch circuit 150b. Therefore, the operations of the CPU 102, the basic random number generator 150, and the monitoring circuit 152 when the start command is generated will be described with reference to the timing chart of FIG.

At the timing of t1, the signal output from the second clock circuit 151 rises from the L level to the H level, that is, the second clock signal is switched to the output state (the signal output from the second clock circuit is the H level state). Then, in the basic random number generator 150, the count value of the counter 150a is updated to n. n is any value between 0 and 65535. Further, since the second clock circuit 151 is connected to the CLK terminal of the monitoring circuit 152 via the reversing device 154, in the monitoring circuit 152, the signal input to the CLK terminal changes from the H level to the L level at the timing t1. It falls and the inverted clock signal switches to the no input state.

At the timing of t2, the signal output from the second clock circuit 151 drops from the H level to the L level, that is, the second clock signal is in the no output state (the signal output from the second clock circuit is in the L level state). When switched, in the monitoring circuit 152, the signal input to the CLK terminal rises from the L level to the H level, and the inverted clock signal switches to the state with input. At this time, in the basic random number generator 150, the count value of the counter 150a is not updated, and the count value remains n.

When the inverting clock signal is switched to the input state, the monitoring circuit 152 outputs a signal corresponding to the input state of the operation signal input to the D terminal at that time from the Q bar terminal. Since the operation signal (H level detection signal) is not input at the timing t2, the start signal is not output from the Q bar terminal. Since the start signal is output from the Q bar terminal (negative logic output terminal), the start signal is not the H level but the L level signal only for the start signal.

After that, when the second clock signal is switched to the output state at the timing of t3, the count value of the counter 150a is updated to n + 1 in the basic random number generator 150. As described above, in the basic random number generator 150, the count value is sequentially updated at the timing when the second clock signal is switched from the state without output to the state with output.

When the start lever 41 is operated at the timing of t4, the signal input to the D terminal of the monitoring circuit 152 rises from the L level to the H level, and the operation signal switches to the input state. However, at such timing t4, since the inverted clock signal is in the state of no input, the start signal remains in the state of no output.

When the inverted clock signal is switched from the state without input to the state with input at the timing of t5, since the operation signal is input to the D terminal in the monitoring circuit 152, the output signal from the Q bar terminal is changed from H level to L. Down to the level. As a result, at such timing t5, the start signal switches from the state without output to the state with output. At this time, the latch signal output from the CPU 102 remains in the no output state. That is, the latch signal is not output at the timing t5 when the start signal is output.

At the timing of t6, the inverted clock signal is switched from the state with input to the state without input, but the output state of the start signal is not changed and the state with output is maintained as it is. That is, even if the inverting clock signal is switched from the state with input to the state without input, the start signal is maintained in the state with output.

After that, when the inverted clock signal is switched from the state without input to the state with input at the timing of t7, a start signal corresponding to the input state of the operation signal at such timing is output. Since the operation signal is in the input state at the timing of t7, the start signal is continuously output in the output state.

When the start signal is switched to the output state at the timing t5, the CPU 102 detects the input of the start signal in the sensor monitoring process S107 of the timer interrupt process, and sets "1" in the first area 112a of the start detection area. To do. Then, in step S620 of the start waiting process, it is determined that the start command has been generated, and the delay process is performed. In the delay processing, the latch signal is output at the timing td when the value of the delay counter 111d becomes 0. That is, the CPU 102 latches at the timing td after the delay time (specifically, the time obtained by multiplying the value of the delay counter 111d by the timer interrupt cycle 1.49 msec) elapses after determining that the start command has occurred. The signal is switched from the state without input to the state with input. As a result, the operation timing of the start lever 41 and the timing at which the latch signal is output are deviated by the delay time.

At the timing t8 when the second clock signal is switched to the output state, the basic random number generator 150 updates the count value of the counter 150a to m + 1. m is any value between 0 and 65535. At this time, the latch signal is input to the basic random number generator 150, but the count value is not latched by the latch circuit 150b at this timing. Then, the basic random number generator 150 latches the count value m + 1 of the counter 150a to the latch circuit 150b at the timing t9 when the second clock signal switches to the no output state. That is, when the start lever 41 is operated at the timing of t4, the count value m + 1 is acquired as the basic random number at the timing t9 instead of the timing t4.

Here, in the basic random number generator 150, the count value of the counter 150a is updated at the timing (t1, t3, t6, etc.) when the second clock signal switches from the state without input to the state with input, and in the latch circuit 150b. The latch of the count value is performed at the timing (t9) when the second clock signal switches from the state with input to the state without input. With such a configuration, it is possible to prevent the count value update timing and the count value latch timing from being the same timing, and the latch timing comes while the count value is being updated, and the count value cannot be latched normally. It is possible to avoid problems.

When the start lever 41 returns to the initial position at the timing t10, the operation signal input to the monitoring circuit 152 is switched from the state with input to the state without input. Since the timing t10 is the timing at which the inverted clock signal is switched from the state with input to the state without input, the output state of the start signal does not change at such a timing. Then, it is detected that no operation signal is input at the timing t11 when the inverted clock signal is switched from the state without input to the state with input, and the start signal is switched from the state with output to the state without output. It should be noted that when the inverting clock signal is in a state without input (for example, timing t10 <timing t <timing t11), the operation signal is switched from the state with input to the state without input, or the inverting clock signal is in a state with input (for example, timing). Even when the operation signal is switched from the state with input to the state without input at t9 <timing t <timing t10), the start signal is switched from the state with output to the state without output at timing t11.

By the way, in the case of a configuration in which the timing at which the operation signal is input is not always grasped but the timing at which the inverting clock signal is input is grasped, the operation signal is switched to the state with input after the inverting clock signal of 1 is input. If the operation signal is switched to the no input state before the next inversion clock signal is input, it is possible that the operation of the start lever 41 cannot be accurately grasped. However, the start lever 41 in the slot machine 10 is configured to have several tens of msec before returning to the initial position after the hand is released, and when the start lever 41 is operated, an operation signal is transmitted for at least several tens of msec. It is designed to be input to the monitoring circuit 152. The clock frequency of the second clock signal output from the second clock circuit 151 is 7.915 MHz, and the period thereof is about 126 nsec. That is, the cycle in which the inverting clock signal is input in the monitoring circuit 152 is sufficiently shorter than the time interval required from when the operation signal is switched to the input state to when it is switched to the input-less state. Therefore, it is possible to avoid a problem that the operation signal is skipped in the monitoring circuit 152 even though the operation signal is output from the start lever detection sensor 41a.

Further, when the latch signal is output from the CPU 102 instead of the monitoring circuit 152, the CPU 102 and the basic random number generator 150 operate based on different clock signals, so that the latch signal is output from the CPU 102. It is also conceivable that the latch signal may be skipped in the basic random number generator 150. However, the latch signal is configured to be output for one interrupt of the timer interrupt process, that is, 1.49 msec, and the period of the second clock signal is about 126 nsec as described above. Therefore, it is possible to avoid a problem that the latch signal is skipped by the basic random number generator 150 even though the latch signal is output from the CPU 102.

Returning to the explanation of the normal processing, when it is determined that the start command has been generated in the start waiting processing, the lottery processing in step S505, the reel control processing in step S506, the medal payout processing in step S507, and the BB state processing in step S508. Are executed in order, and the process returns to step S503.

Next, the lottery process in step S505 will be described with reference to the flowchart of FIG.

In step S701, a random number creation process for creating a random number to be used when determining whether or not the winning combination is performed is performed. As shown in the flowchart of FIG. 24, in step S801 of the random number creation process, the basic random number generated by the basic random number generator 150 is stored in the random number storage area 110 composed of 16 bits. More specifically, the basic random number generator 150 latches the count value at the timing when the latch signal from the CPU 102 is input, and outputs the latched count value to the CPU 102. The CPU 102 stores the count value input to the input port built in the CPU 102 as a basic random number in the random number storage area 110. After that, in step S802, the value of the first counter 111a is added to the random number storage area 110, and in step S803, the value of the second counter 111b is added to the random number storage area 110 to end the random number creation process. That is, in the slot machine 10, a random number is created by adding the latched count value of the basic random number generator 150, the count value of the first counter 111a, and the count value of the second counter 111b.

Here, in the series of processes of steps S108 to S118 in the timer interrupt process, the time required to perform these series of processes is the time required for the basic random number generator 150 to latch the count value, and then the latch result is sent to the CPU 102. It is configured to be longer than the time it takes to be entered. With such a configuration, the acquisition timing of the basic random number (timing at which the process of step S801 is performed) can be delayed from the timing at which the count value latched in this game is input to the CPU 102, and in this game, The latched count value can be reliably stored in the random number storage area 110 as a basic random number.

After creating the random numbers, in step S702, a lottery table for determining the winning or failing of the winning combination is selected. Specifically, the current gaming state of the slot machine 10 is determined, and a lottery table corresponding to the gaming state is selected. The slot machine 10 has two types of gaming states, a normal state and a BB state, and a lottery table corresponding to each gaming state is selected. Further, when the setting state is "setting 1", the lottery table having the lowest expected medal payout value is selected, and when the setting state is "setting 6", the lottery table having the highest expected medal payout value is selected.

The lottery table will be briefly described. FIG. 25 is a lottery table for a normal state selected in the normal state of “setting 3”. In the lottery table, an index value IV equal to the number of winning combinations is set, and each index value IV is uniquely associated with a winning combination and a point value PV is set. ing. That is, in the normal state of the slot machine 10, determination is performed for six types of combinations: replay, bell, watermelon, cherry, one-card combination, and BB.

After selecting the lottery table, the index value IV is set to 1 in step S703, and the determination value DV used when determining the winning or failing of the winning combination is set in the following step S704. In this determination value setting process, a new determination value DV is set by adding the current index value IV and the corresponding point value PV to the current determination value DV. In the initial judgment value setting process, the random value created in step S701 is set as the current judgment value DV, and the current index value IV, 1 and the corresponding point value PV are added to the new judgment value. The judgment value is DV.

After that, in step S705, it is determined whether or not the winning combination corresponds to the index value IV. In the winning / failing determination of the winning combination, it is determined whether or not the determination value DV exceeds 65535. If it exceeds 65535, the process proceeds to step S706, and the winning flag of the winning combination corresponding to the index value IV at that time is set in the winning flag storage area 106a of the RAM 106. For example, when the determination value DV exceeds 65535 when IV = 3, the watermelon winning flag is set in the winning flag storage area 106a in step S706.

By the way, if the set winning flag is any of the re-game winning flag, the bell winning flag, the watermelon winning flag, the cherry winning flag, and the one-card winning combination flag, this winning flag is the game in which the corresponding winning flag is set. It is reset after the end (see S503 of normal processing). On the other hand, when the winning flag is the BB winning flag, the BB winning flag is reset on condition that the BB winning is established. That is, the BB winning flag may be valid over a plurality of games. In step S706 in the state where the BB winning flag is carried over, if the current index value IV is 1 to 5, the winning flag corresponding to the index value IV is set, and if the current index value IV is 6, the BB winning flag is won. Do not set the flag. In other words, in a game in which the BB winning flag is carried over, if one of the replay, bell, watermelon, cherry, and one-card combination is won, the corresponding winning flag is set, while if the BB is won, the corresponding winning flag is set. Do not set the BB winning flag.

If the determination value DV does not exceed 65535 in step S705, it means that the combination corresponding to the index value IV is lost. In such a case, the index value IV is added by 1 in step S707, and in the subsequent step S708, it is determined whether or not there is a role corresponding to the index value IV, that is, whether or not there is a determination target to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index value IV set in the lottery table. If there is a determination target to be determined as to whether or not it is correct, the process returns to step S704 and the determination of whether or not the combination is correct is continued. At this time, in step S704, the current index value IV and the corresponding point value PV are added to the determination value DV (that is, the current determination value DV) used for the determination of whether or not the previous combination is successful to obtain a new determination value DV. In step S705, the winning / failing determination of the winning combination is performed based on the determination value DV. By the way, when the winning / failing judgment of the winning combination is performed using the lottery table shown in FIG. 25, the winning probability of BB is about 1/200, the winning probability of the re-game is about 1.30 /, and the winning probability of the bell is. The winning probability of watermelon is about 1 / 10.9, the winning probability of cherry is about 1 / 73.0, and the winning probability of one piece is 1/128. In addition, the probability of losing any of the roles is about 1 / 1.36.

After setting the winning flag in step S706, or when it is determined in step S708 that there is no determination target to be determined, it means that the winning / failing determination of the winning combination is completed. In such a case, the lottery result command is set in step S709. Here, the lottery result command is a command transmitted to the display control device 81 in order to grasp the result of the winning / failing determination of the winning combination. By receiving the lottery result command, the display control device 81 executes drive control of the upper lamp 63 and the auxiliary display unit 65, for example, to suggest a winning combination. However, in the normal processing, various commands such as the lottery result command are only set in the ring buffer, and the command is not transmitted to the display control device 81. The command transmission to the display control device 81 is performed by the command output process S111 of the timer interrupt process described above.

Then, in step S710, a slide table setting process for setting a slide table (stop table) for reel stop control is performed, and the lottery process is completed. Here, the sliding table is a table in which how much the reels 32L, 32M, and 32R are slid (rotated) and then stopped from the timing when the stop switches 42 to 44 are operated. That is, the sliding table is a arrival symbol (arrival symbol number) that has reached the base point position (lower stage in the present embodiment) when the stop switches 42 to 44 are pressed, and actually stops at the base point position. It is a stop data group from which the relationship with the stop symbol (stop symbol number) can be derived.

In this slot machine 10, as a stop mode for stopping each reel 32L, 32M, 32R, a stop mode for stopping the arrival symbol reaching the base point position as it is when the stop switches 42 to 44 are operated corresponds to the stop mode. A stop mode in which the reel to be stopped is stopped after sliding one symbol, a stop mode in which the reel is stopped after sliding two symbols, a stop mode in which the reel is stopped after sliding three symbols, and a stop mode in which the reel is stopped after sliding four symbols. Five patterns of stopping modes are prepared, as well as stopping modes. Then, a plurality of sliding tables in which any of the above five patterns of stopping modes is set for each symbol number of each reel 32L, 32M, 32R are prepared for each combination.

In this way, by setting the sliding table so that each reel 32L, 32M, 32R stops between the timing when the stop switches 42 to 44 are operated and the time when the specified time (190 msec) elapses, the display window 26L, It is possible to give the player the impression that the symbol arrangement (hereinafter referred to as a stop roll) that stops within a visible range from the 26M and 26R is determined by the operation of the player. In addition, by making it possible to slide up to 4 symbols, it is possible to stop the combination of the winning combination of the lottery and the corresponding symbol on the effective line as much as possible within the specified time. At the same time, it is possible to prevent the combination of the winning combination of the winning combination and the corresponding symbol from stopping on the effective line.

FIG. 26 is an example of a sliding table set when the “replay” symbol of the left reel 32L is stopped on the effective line. The symbol with the number of slips of 0 is the symbol that actually stops in the lower row. For example, if the left stop switch 42 is operated while the 14th "watermelon" symbol of the left reel 32L has reached the lower stage, the left reel 32L stops as it is without slipping, and the 16th "replay" symbol Stops at the top. Further, a symbol having a number in which the number of slips is not 0 means that the reel slides by the number of the described symbols. For example, if the left stop switch 42 is operated while the 8th "bell" symbol of the left reel 32L has reached the lower stage, the left reel 32L slides by 4 symbols and the 12th "replay" symbol is displayed. Stop at the bottom. As described above, in the sliding table, the number of slips when the stop switches 42 to 44 are operated at the timing when the symbols attached to the reels 32L, 32M, 32R reach the lower stage is set for each symbol number.

By the way, in the slide table setting process, the winning flag set in the winning flag storage area 106a of the RAM 106 is confirmed, and the sliding table uniquely corresponding to the set winning flag is set in the sliding table storage area 106b of the RAM 106. set. At this time, in the slot machine 10, the middle reel 32M and the right reel 32R are stopped so that the symbol corresponding to the winning combination of the left reel 32L (hereinafter, referred to as “winning symbol”) stops at either the upper or lower stage. Set the sliding table set so that the winning symbol of is stopped in the middle row. Here, the sliding table in which the winning symbol of the left reel 32L is set to stop at either the upper stage or the lower stage is generally set in the order of left reel 32L → middle reel 32M → right reel 32R. This is to diversify the stop rolls in consideration of the fact that the stop switches 42 to 44 are operated to stop the reels.

Here, the symbol arrangement of each reel 32L, 32M, 32R will be briefly described.

The "replay" symbols are arranged on the reels 32L, 32M, 32R so that the distance between the symbol that reaches the lower row first and the symbol that arrives next is 4 or less. For example, the 4th "replay" symbol and the 7th "replay" symbol of the left reel 32L are arranged so that the interval is 2 symbols, and the 1st "replay" symbol and 6 of the middle reel 32M. The number "replay" symbols are arranged so that the intervals are 4 symbols. As described above, the "replay" symbols are arranged on the reels 32L, 32M, 32R so that the distance between the symbols of the same type is 4 or less. As described above, the reels 32L, 32M, and 32R can be stopped after sliding the reels 32L, 32M, and 32R by a maximum of four symbols from the operated timing of the stop switches 42 to 44. Therefore, by adopting such a symbol arrangement, the "replay" symbol can be stopped at an arbitrary position when the replay winning is established, regardless of the timing when the stop switches 42 to 44 are operated. .. For example, if the middle stop switch 43 is operated when the first "replay" symbol of the middle reel 32M reaches the lower stage, if the middle reel 32M is stopped as it is, this "replay" symbol can be stopped in the lower stage. Yes, if you slide the middle reel 32M by 3 symbols and then stop it, you can stop the 6th "replay" symbol in the upper row, and if you slide the middle reel 32M by 4 symbols and then stop it, you can stop it. "Replay" symbol can be stopped in the middle.

In the slot machine 10, in addition to the "replay" symbol, the "bell" symbol is also arranged on each reel 32L, 32M, 32R so that the distance between the symbols of the same type is 4 or less. Therefore, regardless of the timing at which the stop switches 42 to 44 are operated, the "bell" symbol can be stopped at an arbitrary position when the bell winning is established.

On the other hand, the "watermelon" symbols are not arranged on the reels 32L, 32M, 32R so that the distance between the symbols of the same type is 4 or less. Therefore, for example, if the left stop switch 42 is operated while the 3rd "red 7" symbol of the left reel 32L has reached the lower stage, even if the left reel 32L is slid by 4 symbols, the "watermelon" The symbol cannot be stopped on the effective line. Therefore, even if the watermelon is won and the sliding table set so that the "watermelon" symbol stops on the effective line is set, the "watermelon" depends on the operation timing of the stop switches 42 to 44. In some cases, the symbol does not stop on the effective line and the watermelon prize is not established, so-called omission. In the slot machine 10, in addition to the "watermelon" symbol, the "red 7" symbol is also arranged on each reel 32L, 32M, 32R so as to form a section separated by 5 symbols or more. Further, in the left reel 32L, the "cherry" symbols are arranged so as to form a section separated by 5 symbols or more, and in the middle reel 32M, the "youth" symbol forms a section separated by 5 symbols or more. In the right reel 32R, the "white 7" symbols are arranged so as to form a section separated by 5 symbols or more. Therefore, when one of the BB, watermelon, cherry, and one-card combination is won, it is necessary to operate the stop switches 42 to 44 aiming at stopping the winning symbol on the effective line.

Returning to the explanation of the sliding table setting process, when the BB winning flag and another winning flag are set, the sliding table shown below is set.

When the BB winning flag and the re-game winning flag are set, a slide table for re-game winning is set to give priority to the re-game winning. In the replay winning slide table, the "replay" symbol of the left reel 32L is stopped with priority over the upper or lower row, and the "replay" symbol of the middle reel 32M and the right reel 32R is stopped with priority over the middle row. Is set to.

When the BB winning flag and the small winning combination flag (that is, one of the bell winning flag, the watermelon winning flag, the cherry winning flag, and the one-card winning combination flag) are set, the BB for prioritizing the BB winning is established. Set the sliding table for priority winning. However, since the BB symbol "Red 7" symbol is arranged on each reel 32L, 32M, 32R so as to form a section separated by 5 symbols or more as described above, it depends on the operation timing of the stop switches 42 to 44. May not be able to stop the "Red 7" symbol on the effective line. Therefore, in the BB priority winning sliding table, the reels 32L, 32M, and 32R are set as follows. Regarding the left reel 32L, if it is possible to stop both the "Red 7" symbol and the winning small winning combination symbol on the effective line, "Red 7" will be given priority to stop both symbols on the effective line. Just as if it is possible to stop the symbol in either the upper or lower row, it is impossible to stop the "Red 7" symbol in the upper or lower row, and the winning small winning symbol is described above. If it is possible to stop at each position, the winning small winning combination symbol is set to stop at each of the above positions. The middle reel 32M and the right reel 32R are set to be stopped preferentially if the "red 7" symbol can be stopped in the middle stage, and the "red 7" symbol is placed at each of the above positions. If it is impossible to stop and the winning small winning combination symbol can be stopped at each of the above positions, the winning small winning combination symbol is set to be stopped at each of the above positions.

Next, the reel control process in step S506 will be described with reference to the flowchart of FIG. 27.

In the reel control process, first, in step S901, a rotation start process for starting the rotation of each reel 32L, 32M, 32R is performed.

In the rotation start process, it is confirmed whether or not a predetermined weight time (for example, 4.1 seconds) has elapsed from the time when the reel started rotating in the previous game, and if not, the weight time has elapsed. Wait until you do. When the weight time has elapsed, the weight time for the next game is reset, and the motor control initialization process for setting the rotation start information in the motor control storage area provided in the RAM 106 is performed. By performing this process, the stepping motor control process S106 of the timer interrupt process starts the stepping motor acceleration process, and the reels 32L, 32M, and 32R start rotating. Therefore, even if the player bets a specified number of medals and operates the start lever 41, the reels 32L, 32M, and 32R may not start rotating immediately. After that, it waits until each reel 32L, 32M, 32R rotates at a constant speed at a predetermined rotation speed, and ends the rotation start process. Further, when the rotation speed of each reel 32L, 32M, 32R becomes a constant speed, the CPU 102 can generate a stop command by lighting and displaying a lamp (not shown) of each of the stop switches 42 to 44. Is notified to the players and the like.

Following the rotation start process, in step S902, a pre-stop process is performed.

In the pre-stop processing, as shown in the flowchart of FIG. 28, interrupt waiting processing is first performed in step S1001. In the following step S1002, it is determined whether or not the start command has been generated, and more specifically, whether or not "1" is set in the first area 112a of the start detection area. Then, when "1" is set in the first area 112a of the start detection area, the process returns to the interrupt waiting process in step S1001. That is, when "1" is set in the first area 112a of the start detection area, the process after step S1003 does not proceed until the first area 112a of the start detection area is changed to "0".

Incidentally, as a situation in which it is determined that the start command has been generated in step S1002, when the start lever 41 is still pushed and operated from the processing timing of step S620 to the processing timing of step S1002, the processing of step S620 is performed. If the start lever 41 is operated again after that, it is conceivable that some abnormality has occurred in the monitoring circuit 152 or the like and the start signal is still output.

If the start command has not been generated, the process proceeds to step S1003, and it is determined whether or not any of the stop switches 42 to 44 has been operated. More specifically, the one-area reference process of the operation determination process described above is performed for each of the stop switches 42 to 44. For example, regarding whether or not the left stop switch 42 is operated, the first area 112a of the left stop detection area is referred to, and if "1" is stored, it is determined that the left stop switch 42 has been operated, and "0". Is stored, it is determined that the left stop switch 42 is not operated. If none of the stop switches 42 to 44 is operated, the process returns to the interrupt waiting process in step S1001. If it is determined that any of the stop switches 42 to 44 has been operated, the process proceeds to step S1004, and it is determined whether or not the stop switch corresponding to the rotating reel has been operated, that is, whether or not a stop command has been generated. To do. If the stop command has not been generated, the process returns to the interrupt waiting process in step S1001. When the stop command is generated, the process proceeds to step S1005, and it is determined whether or not the stop command this time is the third stop command, that is, whether or not the stop switch is operated when only one reel is rotating. .. When the stop command this time is the third stop command, an affirmative determination is made in step S1005, and the pre-stop process is terminated as it is. On the other hand, in the case of the first stop command generated when all the reels 32L, 32M, 32R are rotating, or the second stop command generated when the two reels are rotating, the case is denied in step S1005. Along with the determination, the first change processing of the slide table is performed in step S1006, and the pre-stop processing is completed.

Here, the slide table first change process is a process of changing the slide table stored in the slide table storage area 106b of the RAM 106 before stopping the reel corresponding to the stop command. In the sliding table first change processing, it is assumed when the sliding table is set in the sliding table storage area 106b, for example, when the stop switches 43 and 44 other than the left stop switch 42 are operated and the first stop command is generated. When the stop switches 42 to 44 are operated in an operation order different from the operation order of the stop switches 42 to 44, the sliding table is changed. By performing such processing, it is possible to diversify the stop rolls and reduce the frequency of so-called omissions in which the winning flag is invalidated without establishing the winning flag corresponding to the set winning flag. Can be done.

Returning to the description of the reel control process, when the pre-stop process is completed in step S902, it means that the stop switch corresponding to the rotating reel is operated to advance the game, and the stop command is generated. In such a case, the stop control process shown in steps S903 to S909 is performed in order to stop the rotating reel.

That is, in step S903, the symbol number of the arrival symbol that has reached the lower stage at the timing when the stop switch is operated is confirmed. Specifically, the symbol number of the arrival symbol reaching the lower stage is confirmed by the number of excitation pulses output from the time when the detection signal of the reel index sensor is input. In the following step S904, the number of reels to be stopped this time is calculated from the data of the symbol number corresponding to the reached symbol in the slide table set in the slide table storage area 106b. After that, in step S905, the calculated number of slips is added to the symbol number of the reached symbol, and the symbol number of the stop symbol to be actually stopped is determined in the lower row. In step S906, it is determined whether or not the symbol number of the reel arrival symbol to be stopped this time and the symbol number of the stop symbol are equal, and if they are equal, the reel stop process for stopping the rotation of the reel is performed in step S907. Do. After that, in step S908, it is determined whether or not all the reels 32L, 32M, 32R have stopped. If all reels 32L, 32M, 32R are not stopped, the slide table second change process is performed in step S909, and the process returns to the pre-stop process in step S902.

Here, the slide table second change process is a process of changing the slide table stored in the slide table storage area 106b of the RAM 106 after the reels are stopped. In the second slide table change process, the slide table is changed based on the set winning flag and the stop result of the stopped reel. For example, when the bell winning flag is set and the "bell" symbol on the left reel 32L stops in the upper row, the sliding table is changed so that the "bell" symbol on the middle reel 32M stops in the upper or middle row. By performing such processing, it is possible to diversify the stop rolls of the reels to be stopped after that according to the stop result of the reels, and it is possible to reduce the frequency of omissions.

On the other hand, when it is determined in step S908 that all reels 32L, 32M, 32R are stopped, the payout determination process is performed in step S910, and this process is terminated. The payout determination process is a process of setting the number of medals to be paid out on the condition that the combination of winning symbols is lined up on the valid line.

In the payout determination process, a combination of symbols formed on each effective line is derived from the symbol number of the stopped symbol stopped at the lower stage of each reel 32L, 32M, 32R, and whether or not a prize is established on the effective line. To judge. If the winning is established, it is further determined whether or not the winning winning combination matches the winning flag set in the winning flag storage area 106a. When the winning winning combination and the winning flag match, the winning winning combination and the number of payouts corresponding to the winning winning combination are set in the payout information storage area provided in the RAM 106. On the other hand, if the winning combination and the winning flag do not match, the slot machine 10 is put into an error state and an abnormality occurrence process for notifying the occurrence of an error is performed. Such an error state is maintained until the reset switch 72 is operated. When the payout determination is completed for all valid lines, the payout determination process is terminated.

Next, the outline of the medal payout process in step S507 will be described.

In the medal payout process, it is determined whether or not the number of payouts set in the payout information storage area is 0. When the number of payouts is 0, it means that it is determined in the previous payout determination process that the winning prize to be paid out of the medal has not been established. In such a case, it is determined whether or not the re-game winning combination has been established based on the winning combination set in the payout determination process. If the re-game prize is not established, the medal payout process is terminated as it is, and if the re-game prize is established, the re-game setting process for changing the game state to the re-game state is performed, and the medal payout process is performed. finish. In the start waiting process S504 described above, when it is determined that the current game state is the re-game state, the automatic input process is performed.

On the other hand, if the number of payouts set in the payout information storage area is not 0, the same number of medals as the number of payouts is paid out, and the medal payout process is completed. Regarding the payout of medals Specifically, if the count value of the credit counter has not reached the upper limit (the number of stored medals is 50), the number of payouts is added to the count value of the credit counter and the value after addition is added. It is displayed on the credit display unit 60. If the count value of the credit counter has reached the upper limit, or if the count value reaches the upper limit during the addition of the number of payouts, the rotating plate for medal payout is driven to eject medals from the hopper device 51. Pay out to the medal tray 50 via the exit 49. In the medal payout process, the number of payouts displayed on the payout number display unit 62 is also changed according to the payout of medals. When the current gaming state is the BB state, the number of payouts is subtracted from the value of the remaining payout number counter, which will be described later, and the number of remaining payouts displayed on the remaining payout number display unit 61 is subtracted. ..

Next, the BB state processing in step S508 will be described with reference to the flowchart of FIG. 29.

Prior to the explanation of the BB state processing, the BB state will be described. The BB state is composed of a plurality of RB states. The RB state consists of 12 JAC games. The JAC game is a game in which the probability of winning a prize (for example, a bell prize) to which a medal payout privilege is given is extremely high as compared with the normal state. Then, if the winning is established 8 times during the JAC game, the RB state ends even before the JAC game is played 12 times. Further, the BB state ends when the number of medals paid out reaches a predetermined number (specifically, 400 medals). In addition, when the number of medals paid out reaches a predetermined number in the middle of the RB state, not only the BB state but also the RB state ends. This is a device for suppressing the player's gambling spirit and ensuring the soundness of the game by setting an upper limit on the number of medals to be paid out in the BB state. Further, in the present embodiment, the combination of the symbols that shift to the RB state is not set, and the configuration shifts to the RB state immediately after the transition to the BB state and immediately after the end of the RB state. Therefore, it can be said that the BB state is a game in which the game continuously shifts to the RB state until a predetermined number of medals are paid out.

By the way, in the BB state processing, first, in step S1101, it is determined whether or not the current gaming state is the BB state. If it is not in the BB state, the BB determination process shown in steps S1102 to S1105 is performed.

In the BB determination process, it is determined in step S1102 whether or not the BB winning flag is set. If the BB winning flag is set, the process proceeds to step S1103, and it is determined whether or not the BB winning has been established based on the winning winning combination set in the previous payout determination process. Then, when the BB prize is established, the BB start process is executed in step S1104 in order to shift the gaming state to the BB state. Specifically, the BB winning flag is cleared, the BB setting flag is set in the state information storage area 106c of the RAM 106, and the game state is set to the BB state. Further, a process of setting 400 in the remaining payout number counter for counting the number of remaining medals that can be paid out during the BB state provided in the state information storage area 106c and displaying 400 on the remaining payout number display unit 61. I do. After that, the RB start process is performed in step S1105 to end the BB state process. In the RB start process, the RB setting flag is set in the state information storage area 106c of the RAM 106, and the game state is set to the RB state. Further, 8 is set in the remaining payout winning counter for counting the number of winnings established under the RB state, and 12 is set in the remaining JAC game counter for counting the number of remaining games of the JAC game. The remaining payout winning counter and the remaining JAC winning counter are provided in the state information storage area 106c. Further, the determination of the current gaming state in step S1101 or the like is executed based on whether or not the setting flag corresponding to the state information storage area 106c is set, and when none of the setting flags is set. Determines that the current gaming state is the normal state.

On the other hand, when the BB winning flag is not set (when step S1102 is NO) or when the BB winning is not established (when step S1103 is NO), the book is performed without executing the BB start process or the like. End the process.

If it is determined in step S1101 that the current gaming state is the BB state, the process proceeds to step S1106, and it is determined whether or not the winning is established based on the winning winning combination set in the previous payout determination process. .. If a prize is established, the value of the remaining payout prize counter is subtracted by 1 in step S1107. After that, or when it is determined in step S1106 that the winning is not established, one JAC game has been exhausted, so the value of the remaining JAC game counter is subtracted by 1 in step S1108. Subsequently, in step S1109, it is determined whether or not either the remaining payout winning counter or the remaining JAC game counter becomes 0. When any of them is 0, that is, when the prize is established 8 times or the JAC game is digested 12 times, it means that the end condition of the RB state is satisfied. And RB end processing for clearing the value of the remaining JAC game counter is performed. In the following step S1111, it is confirmed whether or not the count value of the remaining payout counter is 0. If it is not 0, it means that the number of medals paid out during the BB state has not reached the predetermined number and the end condition of the BB state is not satisfied. Therefore, the process proceeds to step S1112 and the RB start described above is started. After performing the process, this process ends.

Further, when neither the value of the remaining payout winning counter and the remaining JAC game counter is 0 in step S1109, that is, when the winning has not been established 8 times and the JAC game has not been digested 12 times, step S1113 Proceed to, and confirm whether or not the count value of the remaining payout counter is 0. If it is not 0, it means that the number of medals paid out during the BB state has not reached the predetermined number and the end condition of the BB state is not satisfied, so this process is terminated as it is. On the other hand, when the count value of the remaining payout counter is 0, it means that the end condition of the BB state is satisfied, so that the special game state end processing shown in steps S1114 to S1115 is performed. In the special game state end process, first, in step S1114, the RB end process described above is performed. After that, in step S1115, the BB end process of appropriately clearing the BB setting flag, various counters, and the like and performing the ending process is performed. Further, even when the count value of the remaining payout counter is 0 in step S1111, it means that the end condition of the BB state is satisfied, so that the BB end process is performed in step S1115. After performing the BB end process, the state transition process is executed in step S1116 to end the BB state process. Here, the state transition process is a process for returning the game state to the normal state, for example, setting an end command to be transmitted so that the display control device 81 knows that the BB state has ended, or a predetermined state. A process of waiting until the time (for example, the time until the ending display ends) elapses is performed.

According to the present embodiment described in detail above, the following excellent effects are obtained.

In slot machines, there is still room for ingenuity in the relationship between the process of confirming the signal input status from the sensor and other processes.
It should be noted that the above problem is not limited to the slot machine as illustrated above, but also applies to other gaming machines that advance the game based on the detection of predetermined conditions.
The present invention has been made in view of the above-exemplified circumstances and the like, and an object of the present invention is to provide a gaming machine capable of suitably using detection of predetermined conditions for gaming.
When the start lever 41 is operated and a start command is generated, the count value of the basic random number generator 150 is latched not at the operation timing of the start lever 41 but at the timing after the delay time has elapsed from the operation timing. It was configured to be. Since the delay time changes depending on the value of the delay counter 111d, this configuration allows the latch timing of the count value of the basic random number generator 150 even if the start lever 41 is operated at a fixed cycle. Can be changed. As a result, when a winning random number is created using a sensor or the like, the start lever 41 is operated illegally aiming at the count value of the basic random number generator 150, or the main control is performed at the timing when the count value is generated. It is possible to make it difficult to attach a fraudulent board capable of outputting a fraudulent signal that causes the device 101 to erroneously recognize that a start command has been generated, and to make it difficult to illegally acquire a winning random number. It becomes possible.

The interrupt wait processing is performed by the normal processing that is started and repeated when the power is turned on, and the interrupt wait processing is terminated when the value of the update counter 111c changes, that is, when the timer interrupt processing is performed. It was configured. Then, in the interrupt waiting process, the value of the delay counter 111d is repeatedly updated until the value of the update counter 111c changes. With such a configuration, the time from the start to the end of the interrupt waiting process can be made random. While the timer interrupt processing is periodically performed every 1.49 msec, the timing for starting the interrupt waiting processing, more specifically, the timing for acquiring the value of the update counter 111c in step S402 is from the power-on to the interrupt waiting processing. It changes depending on other processing performed up to. Therefore, if the interrupt wait processing is started immediately after the timer interrupt processing is completed, the delay counter 111d can be updated with a time obtained by subtracting the time required for the timer interrupt processing from 1.49 msec. On the other hand, if the timer interrupt process is performed immediately after step S402, only the time for updating the delay counter 111d once can be secured. As a result, the number of updates of the delay counter 111d performed in the interrupt waiting process can be made random, and the delay time from the occurrence of the start command to the output of the latch signal by the CPU 102 can be made random. be able to.

Certainly, for example, in normal processing, the start timing and end timing of timer interrupt processing are monitored, and the delay counter 111d is updated from the end timing of timer interrupt processing to the start timing of the next timer interrupt processing, that is, interrupt waiting processing. It is also possible to make the start timing of the timer interrupt process dependent on the end timing of the timer interrupt process. Even in such a configuration, the time from the start to the end of the interrupt waiting process can be random as in the above embodiment. However, in such a configuration, since the timer interrupt processing is started every 1.49 msec, there is a time constraint that the start timing of the interrupt wait processing is within 1.49 msec from the start timing of the timer interrupt processing. It becomes. In addition, there is a restriction that the interval between the start timing of the first interrupt wait processing and the start timing of the next interrupt wait processing, that is, the start interval of the interrupt wait processing is less than two cycles of timer interrupt processing, that is, less than 2.98 msec. It will be. Therefore, based on these restrictions, there is a possibility that the count value of the delay counter 111d is illegally targeted so that the delay time after the start command is generated becomes constant for each game. On the other hand, in the above embodiment, since the start timing of the interrupt wait processing does not depend on the start timing and the end timing of the timer interrupt processing, the above-mentioned restrictions do not occur and the value of the delay counter 111d is illegally targeted. It is possible to reduce the possibility.

In the normal process, when the interrupt wait process is completed, a process of determining whether or not the start lever 41 (for example, step S620) has been operated is performed using the result of the sensor monitoring process of the timer interrupt process. By configuring the determination process to be performed after the interrupt wait process is completed, it is possible to shorten the interval from the end of the timer interrupt process to the execution of the determination process. In the configuration without interrupt wait processing, the interval is the maximum time obtained by subtracting the time required for timer interrupt processing from 1.49 msec, while in the configuration with interrupt wait processing, the maximum is 1.49 msec. The time required for timer interrupt processing is reduced, and the time required for performing the processing of steps S403 to S406 once and the time required for performing the processing of step S408 after making a negative determination in step S407 are reduced. Because it becomes. As a result, it is possible to make a determination related to the progress of the game, the game situation, etc., such as whether or not the start lever 41 has been operated, using the result of the sensor monitoring process performed at a closer timing. Therefore, it is possible to reduce the time lag that occurs between the operation of the start lever 41 or the like performed by the player or the like and the progress of the game or the like accompanying the operation. As a result, even if the count value of the basic random number generator 150 is latched after the delay time elapses after the start command is generated, the player is prevented from feeling uncomfortable with the time lag. It becomes possible to do.

In addition to performing the interrupt waiting process before the operation determination process for determining whether or not the start lever 41 (for example, step S620) has been operated, steps S303 to S308 of the winning probability setting process and the start of the start wait process are started. The configuration is such that it is performed in a looping process such as a preparatory process (steps S604 to S620). With such a configuration, it is possible to prevent the slot machine 10 from malfunctioning.

Here, consider a configuration in which interrupt wait processing is not performed in the loop processing.

For example, in the loop processing of steps S303 to S308 of the winning probability setting processing, it is determined in step S307 whether or not the reset switch 72 has been operated, and if it is determined that the reset switch 72 has been operated, the set value is updated. Since the CPU 102 operates when the first clock signal is input, the operating cycle of the CPU 102 is equal to the cycle of the first clock signal and is about 125 nsec. Further, since the timer interrupt processing is performed every 1.49 msec, the CPU 102 can perform an operation (processing operation) 1000 times or more between the timer interrupt processing and the next timer interrupt processing. .. Therefore, in a configuration in which interrupt wait processing is not performed in the loop processing of winning probability setting processing, for example, if timer interrupt processing is performed immediately before processing in step S303, steps S303 to the next timer interrupt processing are performed. The loop processing of S308 can be repeated a plurality of times.

In the process of determining whether or not the reset switch 72 of step S307 has been operated, the entire area reference process is performed. That is, all areas 112a to 112c of the reset detection area are referred to, and if "011" is stored, it is determined that the reset switch 72 has been operated, and if "011" is not stored, the reset switch is switched. It is determined that 72 is not operated. In such a case, in a configuration in which interrupt waiting processing is not performed, there is a possibility that the determination processing in step S307 is performed a plurality of times under the condition that "011" is stored, and the reset switch 72 is operated only once. This will lead to a malfunction in which the set value is updated multiple times even though it has not been set.

On the other hand, in the configuration in which interrupt waiting processing is performed before determining whether or not the reset switch 72 has been operated, when the processing in step S307 is performed in a situation where "011" is stored in the reset detection area. When the process of the next step S307 is performed, "110" or "111" is stored in the reset detection area, and it is avoided to repeatedly determine affirmatively that the reset switch 72 has been operated in step S307. be able to. As a result, it is possible to avoid a malfunction in which the set value is updated a plurality of times for one operation of the reset switch 72, and it is possible to have the manager or the like of the game hall set the set value desired by himself / herself.

Similarly, in the loop processing of the pre-start preparation processes S604 to S620, it is determined in step S606 whether or not the credit insertion switches 56 to 58 have been operated, and if it is determined that the credit insertion switches 56 to 58 have been operated, the credit insertion processing is performed in step S612. .. Even in such a loop process, in a configuration in which the interrupt wait process is not performed, for example, if the timer interrupt process is performed immediately before the process of step S604 is performed, the loop process of steps S604 to S620 is performed before the next timer interrupt process is performed. It can be repeated multiple times.

In the process of determining whether or not the credit insertion switches 56 to 58 of step S606 have been operated, the entire area reference process is performed. That is, referring to all areas 112a to 112c of each credit insertion detection area, if "011" is stored, it is determined that the corresponding credit insertion switch has been operated, and if "011" is not stored. Judges that the corresponding credit insertion switch is not operated. In such a case, in a configuration in which interrupt waiting processing is not performed, there is a possibility that the determination processing in step S606 may be performed a plurality of times in a situation where "011" is stored, and the credit insertion switches 56 to 58 are operated only once. There is a possibility that it is determined that the operation has been performed multiple times even though the operation has not been performed. This leads to a malfunction in which a plurality of virtual medals are inserted even though the third credit insertion switch 58 is operated to insert only one virtual medal, for example.

On the other hand, in the configuration in which interrupt waiting processing is performed before determining whether or not the credit insertion switches 56 to 58 have been operated, the processing in step S606 is performed under the condition that "011" is stored in the credit insertion detection area. When the next step S606 is performed, "110" or "111" is stored in the credit insertion detection area, and the credit insertion switches 56 to 58 are operated in step S606. It is possible to avoid repeated affirmative judgments. As a result, it is possible to avoid a malfunction in which the corresponding virtual medals are inserted a plurality of times for one operation of the credit insertion switches 56 to 58, and the player can insert the virtual medals intended by the player. It will be possible.

The sensor information storage area 112 of the RAM 106 is composed of three storage areas of the first to third areas 112a to 112c. With such a configuration, the history of the presence / absence of signal input from each detection sensor can be stored, and it is possible to determine whether or not the operation has been performed using the history of presence / absence of signal input. Further, by configuring the reset switch 72 and the credit input switches 56 to 58 to perform all area reference processing, it is possible to preferably avoid malfunction of the slot machine 10. If one area reference process is performed for the switches 56 to 58 and 72, the steps S307 in the loop process of the winning probability setting process S303 to S308 and the step in the loop process of the pre-start preparation process S604 to S620 In S606, only the first area 112a of the corresponding detection area will be referred to. As described above, the operation cycle of the CPU 102 is sufficiently faster than the time required from the start to the end of the operations of the switches 56 to 58, 72. Therefore, when one area reference processing is performed on the switches 56 to 58, 72, "1" is repeatedly stored in the first area 112a for a certain period of time even if interrupt waiting processing is performed. This is because there is a possibility that it is determined that the operation has been performed a plurality of times for one operation.

The interrupt wait processing is configured to be performed in the pre-start preparatory processing of normal processing. The pre-start preparatory process is a process that is repeated until a start command is generated, and the time from the end of the previous game to the generation of the start command changes depending on the timing at which the player operates the start lever 41. .. Therefore, the number of pre-start preparatory processes performed before the start command is generated is random, and the number of interrupt wait processes performed accordingly is also random. As a result, the number of updates of the delay counter 111d performed until the start command is generated can be made random.

The delay counter 111d is updated in step S609 of the pre-start preparation process. The pre-start preparatory process is a process that is repeated until a start command is generated, and the time from the end of the previous game to the generation of the start command changes depending on the timing at which the player operates the start lever 41. .. Therefore, the number of pre-start preparatory processes performed before the start command is generated is random, and the number of updates of the delay counter 111d performed before the start command is generated can be random.

Here, since the generation timing of the start command depends on the operation of the start lever 41 by the player, the start lever 41 is illegally set so that the time from the end of the previous game to the generation of the start command is constant. It may be manipulated. However, the time required to perform the pre-start preparatory process once varies depending on the game situation and the like. For example, even when only the processing time required for betting a medal is considered, the time required for the credit insertion processing and the insertion determination are determined depending on whether the credit insertion switch 56 to 58 is operated or the medal is actually inserted. This is because the time required for processing changes. Therefore, it is difficult to fix the number of pre-start preparatory processes to a constant level. Furthermore, by operating the first credit insertion switch 56 for each game, the processing time required for betting medals is fixed, and the time from the end of the previous game to the occurrence of the start command is fixed. At the same time, it is possible that the number of pre-start preparatory processes performed within the time period is also fixed. However, in the pre-start preparatory processing, the interrupt waiting processing is performed in steps S605 and S619, and as described above, the time from the start to the end of the interrupt waiting processing is random. Therefore, even if the start lever 41 is illegally operated so that the time from the end of the previous game to the occurrence of the start command is constant, the number of pre-start preparation processes performed within that time is required. Cannot be fixed. As a result, the number of updates of the delay counter 111d in the pre-start preparation process cannot be fixed to be constant, and the count value of the delay counter 111d is aimed at so that the delay time after the start command is generated becomes constant for each game. The fraudulent operation of the start lever 41 can be made difficult.

The interrupt waiting process is performed in steps S1001 to S1004 in the pre-stop process of the normal process, that is, between the time when the rotating reel can be stopped and the time when the stop command is issued. The processes of steps S1001 to S1004 are processes that are repeated until a stop command is issued, and the player stops the time from when the rotating reel can be stopped until the stop command is generated. It changes depending on the timing of operating the switches 42 to 44. Therefore, the number of times of processing in steps S1001 to S1004 performed before the stop command is generated becomes random, and the number of times interrupt waiting processing is performed accordingly also becomes random. As a result, the number of updates of the delay counter 111d performed until the stop command is generated can be made random.

A delay counter 111d is provided in the RAM 106 of the CPU 102, and the CPU 102 updates the delay counter 111d. That is, the delay period is determined based on the value of the soft-free counter. With such a configuration, it becomes possible to make it difficult for the winning random numbers to be illegally acquired. Certainly, it is also possible to determine the delay period using the count value generated by the hardware counter separate from the CPU 102. However, in such a configuration, there is a concern that the hardware counter may be changed to an invalid hardware counter that outputs only a value of 1, for example, and if such a change is made, the delay period will be the value of 1 for each game. It will be a certain period based on. Then, after setting the delay period to a certain period, the start lever 41 is operated aiming at the count value of the basic random number generator 150 when a winning random number is created using a sensor or the like, or the above-mentioned count. There is a concern that a fraudulent board capable of outputting a fraudulent signal that causes the main controller 101 to erroneously recognize that a start command has been generated may be mounted at the timing when the value is generated. On the other hand, in the configuration in which the delay counter 111d is provided in the RAM 106 of the CPU 102 and the CPU 102 updates the delay counter 111d, the above fraud can be made difficult unless the CPU 102 itself is changed to an illegal CPU. ..

The value of the delay counter 111d is not cleared even when the RAM is cleared. With such a configuration, an invalid signal indicating RAM clear is input to the CPU 102, the value of the delay counter 111d is changed to the initial value, and then the basic random number generator 150, No. 1 when a winning random number is created. It is possible to prevent fraudulent operation of the start lever 41 by aiming at the values of the 1st counter 111a and the 2nd counter 111b.

The first counter 111a and the second counter 111b are provided in the RAM 106 of the CPU 102, and in the random number creation process, the count values of these counters 111a and 111b are added to the basic random numbers generated by the basic random number generator 150. With such a configuration, the cycle in which the random numbers to be created and the random numbers to be won are created can be made more random than the configuration in which the random numbers are created using the count value of the counter of 1, and the winning is achieved. It becomes possible to make it difficult to illegally obtain the random number.

A first counter 111a and a second counter 111b are provided in the RAM 106 of the CPU 102, and the CPU 102 updates the counters 111a and 111b. That is, a random number is created by adding the value of the soft-free counter to the value of the basic random number generator 150, which is a hardware counter. With such a configuration, it becomes possible to make it difficult for the winning random numbers to be illegally acquired. Certainly, it is also possible to use the count value latched by the hardware random number generator such as the basic random number generator 150 as it is as a random number. However, in the case of such a configuration, there is a concern that the hardware random number generator may be changed to, for example, an invalid hardware random number generator that always outputs a count value that is BB winning, and if such a change is made. , The amusement park where the slot machine 10 is installed will be seriously damaged. On the other hand, in the configuration in which the first counter 111a and the second counter 111b are provided in the RAM 106 of the CPU 102 and the CPU 102 updates these counters 111a and 111b, even if the hardware random number generator is changed to the above-mentioned invalid hardware random number generator, the first counter 111a and the second counter 111b are updated. By adding the count values of the 1st counter 111a and the 2nd counter 111b, it is possible to change to a random number that does not win the BB.

The values of the first counter 111a and the second counter 111b are configured not to be cleared even when the RAM is cleared. With such a configuration, an invalid signal indicating RAM clear is input to the CPU 102, the values of the first counter 111a and the second counter 111b are changed to the initial values, and then the winning random numbers are created. It is possible to prevent fraudulent operation of the start lever 41 by aiming at the values of the random number generator 150, the first counter 111a, and the second counter 111b.

In addition, if the count value latched by the hardware random number generator is used as it is as a random number, in addition to the possibility of being changed to the above-mentioned invalid hardware random number generator, the following problems are also a concern. Will be done. That is, in the hardware random number generator, the oscillator outputs a clock signal to the counter at a constant cycle, and the counter is updated based on the input of the clock signal. Therefore, for example, if the transmitter stops outputting the clock signal due to a failure or the like, the counter will not be updated. Therefore, in the game after the clock signal is no longer output, the winning / failing judgment of the winning combination is always performed using the same counter value, and there is a concern that the player or the game field where the slot machine is installed may suffer a disadvantage. To.

Therefore, a monitoring circuit 152 composed of a D flip-flop circuit is provided in the main control device 101, and the start detection sensor 41a is connected to the D terminal of the monitoring circuit 152 and the second clock circuit 151 is connected to the CLK terminal. Then, the CPU 102 was connected to the Q bar terminal. In such a configuration, when the second clock signal is no longer output from the second clock circuit 151 due to a failure or the like, or when the second clock signal remains output, the monitoring circuit 152 is second. Since the input state of the clock signal (more specifically, the inverted clock signal) does not change, the start signal is not output to the CPU 102. Therefore, even if the operation signal is output from the start detection sensor 41a under these circumstances, the reels 32L, 32M, and 32R do not start rotating, and the player or the game hall where the slot machine 10 is installed is disadvantageous. You can avoid suffering. When the second clock signal is not input to the basic random number generator 150 or remains input, a random number is always created using the same basic random number in a configuration in which the game can be played thereafter. This is because it will be different.

Further, in such a configuration, the slot machine 10 is provided with the reels 32L, 32M, 32R not starting to rotate even if the start lever 41 is operated by the player or the manager of the game hall where the slot machine 10 is installed. It is possible to notify that an abnormality has occurred. Therefore, it is possible to promptly discover that an abnormality has occurred in the second clock circuit 151, and the player or the amusement place where the slot machine 10 is installed suffers a disadvantage due to the abnormality in the second clock circuit 151. Can be suitably avoided.

Certainly, a monitoring means for monitoring whether or not the second clock circuit 151 periodically outputs the second clock signal is provided, and if the second clock signal is not periodically output, the CPU 102 causes an abnormality. It is possible to notify the player, the manager of the game hall, or the like that some abnormality has occurred in the second clock circuit 151, even if the configuration is such that the processing is performed when an abnormality occurs, such as notifying. However, in such a configuration, it becomes necessary to store the program for performing the processing when an abnormality occurs in the main control device 101 or the CPU 102 itself, and there is a concern that the storage capacity may be increased. Further, when some abnormality occurs in the monitoring means instead of the second clock circuit 151, the game continues without being able to find the abnormality even though the abnormality has occurred in the second clock circuit 151. There is also concern that it may be done.

On the other hand, in the case of the above embodiment in which the start detection sensor 41a and the CPU 102 are connected via the monitoring circuit 152, the game is played through the fact that the reels 32L, 32M, and 32R do not start rotating even though the start lever 41 is operated. It is possible to directly notify the person of the occurrence of an abnormality, and it is not necessary for the CPU 102 to perform processing when an abnormality occurs. Further, if any abnormality occurs in the monitoring circuit 152 itself, the output states of the start signal and the latch signal do not change. Therefore, even in such a case, the player cannot play the subsequent game, so that the player is informed of the abnormality. It is possible to notify directly. Therefore, while resolving each of the above concerns, it is possible to reduce the chance that the player or the game hall where the slot machine 10 is installed suffers a disadvantage when an abnormality occurs inside the slot machine 10 with a relatively simple configuration. ..

In the basic random number generator 150, the count value of the counter 150a is updated at the timing when the second clock signal is switched from the state without input to the state with input, and the latch of the count value in the latch circuit 150b is input by the second clock signal. The configuration is such that it is performed at the timing of switching from the presence state to the no input state. With such a configuration, it is possible to prevent the count value update timing and the count value latch timing from being the same timing, and the latch timing comes while the count value is being updated, and the count value cannot be latched normally. It is possible to avoid problems.

Since the monitoring circuit 152 is provided separately from the CPU 102 in the main control device 101, it is possible to notify the abnormality of the slot machine 10 without the CPU 102 monitoring whether or not the second clock circuit 151 is normal. Therefore, it is possible to reduce the processing load of the CPU 102, and it is also possible to suppress the increase in the storage capacity of the CPU 102 by eliminating the need for a program related to the monitoring control of the second clock circuit 151.

Further, even if some abnormality occurs in the monitoring circuit 152 itself instead of the second clock circuit 151, the abnormality can be easily detected. That is, when some abnormality occurs in the monitoring circuit 152, the output state of the start signal becomes constant regardless of the input state of the operation signal or the second clock signal. This is because the reels 32L, 32M, 32R do not start rotating even though the player operates the start lever 41, or the start signal is output even though the player does not operate the start lever 41. It leads to the occurrence of an abnormal event such as the state of being left as it is. Therefore, it becomes possible for the player, the manager of the game hall, or the like to easily discover that some abnormality has occurred in the slot machine 10. As a result, when an abnormality occurs inside the slot machine 10 while avoiding a problem such as being unable to find an abnormality in the second clock circuit 151 due to an abnormality occurring in the monitoring circuit 152. It is possible to reduce the chance that the player or the playground where the slot machine 10 is installed suffers a disadvantage.

A first clock circuit 103 for inputting a clock signal to the CPU 102 and a second clock circuit 151 for inputting a clock signal to the basic random number generator 150 are separately provided, and the clock signals output from these clock circuits 103 and 151 are generated. The configuration is not synchronized. With such a configuration, the timing at which the latch circuit 150b latches the count value in the basic random number generator 150 and the acquisition timing at which the CPU 102 acquires a random number from the latch circuit 150b are synchronized, and the CPU 102 normally acquires the basic random number. It is possible to avoid the problem of not being able to occur.

In the reel control process, the presence or absence of the stop command is determined on the condition that the start command has not been generated. That is, if the start command is generated while the reel is rotating, the stop command is invalidated. With such a configuration, when an abnormality occurs in the second clock circuit 151 while the second clock signal is being output, the abnormality can be quickly detected. If the above abnormality occurs in the middle of the game, some abnormality occurs in the slot machine 10 for the player or the manager of the game hall because the corresponding reel cannot be stopped even if the stop switch is operated. This is because it is possible to notify what has been done. Further, when the abnormality occurs and the reels 32L, 32M, 32R start rotating in a situation where the start lever 41 is not operated, the player feels uncomfortable, but the stop switch 42 is used to end the game. It is possible to operate ~ 44. However, since the corresponding reel cannot be stopped even if the stop switch is operated, it is possible to notify the player, the manager of the game hall, or the like that some abnormality has occurred in the slot machine 10.

The content is not limited to the description of the above-described embodiment, and may be implemented as follows, for example.

(1) In the above embodiment, the value of the delay counter 111d is added by 1 in the interrupt waiting process and the timer interrupt process, but the process of adding the value of the delay counter 111d may not be performed. That is, the value of the delay counter 111d is incremented by 1 only in step S609 of the start waiting process. Even with such a configuration, the number of updates of the delay counter 111d in the pre-start preparation process is random, so it is possible to make it difficult to obtain a random number that is illegally won. Become.

Further, the value of the delay counter 111d may be added by 1 in the interrupt waiting process performed in the pre-start preparation process, and the value of the delay counter 111d may not be added by 1 in the other interrupt waiting process.

However, in the case where the value of the delay counter 111d is updated in the interrupt wait processing as in the above embodiment, the number of updates or the update value of the delay counter 111d for each pre-start preparation process is indefinite. It becomes possible to make it more difficult to obtain a random number that is illegally won.

(2) If the interrupt waiting process performed in the pre-start preparatory process updates the value of the second counter and the other interrupt wait process does not update the value of the second counter, all reels 32L, 32M, The value of the second counter may be updated between the time when the 32R is stopped and the time when the start command is issued. For example, instead of or in addition to the pre-start preparation process, the value of the second counter is updated in the medal payout process. In the medal payout process, the time from the start to the end changes depending on the number of medals paid out. Therefore, even when the value of the second counter is updated in such processing, it can be expected to have the same effect as that of the above-described embodiment.

(3) In the above embodiment, the basic random number generator 150, the first counter 111a, and the second counter 111b are provided, and the latched count value of the basic random number generator 150, the count value of the first counter 111a, and the first The random number is created by adding the count value of the two counters 111b, but the present invention is not limited to this configuration, and the count value of the basic random number generator 150 may be used as it is as a random number. With such a configuration, since the winning count value is generated in a fixed cycle in the basic random number generator 150, there is a possibility that a fraudulent act of generating a start command aiming at the count value may occur. However, in the configuration in which the count value of the basic random number generator 150 is latched after the delay time has elapsed from the generation of the start command, even if the start command is generated in a cycle that is several times the natural number of the cycle, the basic random number is generated. The timing of latching the count value of the generator 150 can be shifted from the cycle. Therefore, it is possible to make it difficult for the winning random numbers to be illegally acquired.

Further, a random number may be created by adding the count value of the first counter 111a and the count value of the second counter 111b without providing the basic random number generator 150, or the count value of the first counter 111a may be used. Needless to say, the configuration may be used as a random number as it is, or the count value of the second counter 111b may be used as a random number as it is.

(4) In the above embodiment, when a start command is generated, the process of subtracting until the value of the delay counter 111d becomes 0 is performed, but the process of adding until the value of the delay counter 111d becomes 0 is performed. It may be configured to be performed. Even in the case of such a configuration, it is clear that the same action and effect as those of the above-described embodiment are obtained. Further, in such a configuration, it is possible to simplify the program configuration of the delay counter processing.

(5) In the above embodiment, the process of subtracting the value of the delay counter 111d until it becomes 0 is performed by the timer interrupt process, but it may be performed by the normal process. Specifically, in the delay processing of the normal processing, a process of subtracting 1 from the value of the delay counter 111d after setting the delay flag is performed, and then it is determined whether or not the value of the delay counter 111d is 0. .. If the value of the delay counter 111d is not 0, the subtraction process is repeated until the value of the delay counter 111d becomes 0. With such a configuration, it is possible to shorten the delay time. When the delay counter 111d is subtracted by the timer interrupt process, the subtraction process can be performed only every 1.49 msec, but when the delay counter 111d is subtracted by the normal process, the subtraction process can be performed only every 1.49 msec. This is because the subtraction process can be performed about every 125 nsec.

(6) In the above embodiment, when a start command is generated, the latch signal is output after the value of the delay counter 111d becomes 0, but the configuration is not limited to this, and the delay counter 111d is not limited to this. The latch signal may be output after the value of 1 becomes 1, or the latch signal may be output after the value of the delay counter 111d becomes 10. That is, the latch signal may be output after reaching a specific value irrelevant to the value of the delay counter 111d at that time.

(7) In the above embodiment, one delay counter 111d is provided in the RAM 106 of the CPU 102, and the value of the delay counter 111d is updated in the normal processing and the timer interrupt processing. However, the delay counter is updated in the normal processing. And the delay counter updated in the timer interrupt processing may be provided separately.

(8) In the above embodiment, the basic random number generator 150 is provided, and the latched count value of the basic random number generator 150, the count value of the first counter 111a, and the count value of the second counter 111b are added. By doing so, a random number is created, but it goes without saying that a random number may be created by subtracting these count values.

(9) The position where the interrupt wait processing is provided in the normal processing is arbitrary as long as it is before the processing for making a judgment using the processing result of the timer interrupt processing. Therefore, for example, an interrupt waiting process may be provided between steps S1002 and S1003 in the pre-stop processing, or an interrupt waiting process may be provided in the middle of the input determination process. This is because in the insertion determination process, it is determined whether or not a medal has been inserted based on the detection signal from the insertion medal detection sensor 45a.

Further, it may be before the process of making a judgment using the processing result of the timer subtraction process, not before the process of making a judgment using the processing result of the sensor monitoring process as described above. For example, in the rotation start process, it is confirmed whether or not a predetermined weight time (for example, 4.1 seconds) has elapsed from the time when the reel started rotating in the previous game. Therefore, if the timer subtraction process is used to subtract the timer that measures the wait time, the interrupt wait process is performed before confirming whether or not the wait time has elapsed. Alternatively, in a configuration in which a process of determining whether or not the output of a predetermined command is completed and waiting as it is if it is not completed, an interrupt wait process may be performed before the determination process is performed. .. With these configurations, the standby time can be effectively used as the update time of the delay counter 111d.

(10) In the above embodiment, the interrupt waiting process is terminated when the value of the update counter 111c changes, but the amount of change in the value of the update counter 111c is arbitrary. That is, in step S407, a negative determination may be made when the value of the update counter 111c changes by 3 from the value acquired in step S402, or a negative determination may be made when the value of the update counter 111c changes by 1. That is, in the above embodiment, when the value of the update counter 111c changes, a negative determination is made regardless of the amount of change and the interrupt waiting process is terminated. However, the amount of change is set in advance and the update counter 111c is terminated. When the value of is changed by the amount of change, that is, when the timer interrupt processing is performed a predetermined number of times, a negative determination may be made and the interrupt waiting processing may be terminated.

(11) In the above embodiment, as the counter used for creating the random number, the first counter 111a updated in the timer interrupt process and the second counter 111b updated in the normal process are separately provided. The value of the counter of 1 may be updated by the normal processing and the timer interrupt processing.

Further, when the above configuration is applied to a game machine that does not have a basic random number generator, the value of the counter may be used as it is as a random number, or a predetermined arithmetic process such as inverting the value of the counter may be performed. The value obtained by performing the above may be used as a random number.

(12) In the above embodiment, when the number of updates of the delay counter 111d in the interrupt waiting process is excluded, the value of the delay counter 111d is updated by 1 every time the pre-start preparation process is performed. 2 may be updated, or 3 or more may be updated. That is, the number of updates or the update value of the delay counter 111d for each pre-start preparation process is arbitrary.

(13) In the above embodiment, in the start waiting process, the processes of steps S604 to S620 are looped, but the processes of steps S601 to S620 may be looped. However, when the pre-start preparation process includes the processes of steps S601 to S603, it is determined whether or not the medal acceptance processing and the automatic insertion processing are the first processing, and this is the first processing. In that case, it is necessary to perform the corresponding processing, and if it is not the first time, it is necessary to have a configuration in which the processing proceeds to the subsequent processing (step S604, step S607) without performing the corresponding processing. With such a configuration, the time from the start to the end of the pre-start preparatory process can be made more indefinite, and the number of updates of the delay counter 111d performed until the start command is generated is more random. Can be.

As described above, the pre-start preparatory process is a process that starts when the reel is not rotating and ends when a start command is generated, and may be a process that is repeated until the start command is generated. ..

(14) In the above embodiment, the update process of adding or subtracting the value of the delay counter 111d is performed, but it goes without saying that the update process of adding or subtracting two or more values may be performed. No. The same applies to the first counter 111a, the second counter 111b, and the counter 150a of the basic random number generator 150.

(15) The position where the delay counter 111d is updated in the pre-start preparation process is arbitrary. That is, the delay counter 111d may be updated immediately after the abnormality confirmation process, or the delay counter 111d may be updated immediately after the closing determination process. Even with these configurations, it is clear that the same effects as those of the above-described embodiment are obtained.

(16) The latch circuit 150b of the basic random number generator 150 and the CPU 102 may be connected in reverse by 16 bits.

(17) In the above embodiment, the counter 150a of the basic random number generator 150, the first counter 111a, and the second counter 111b are each composed of 16 bits, but may be composed of 8 bits. It may be composed of 4 bits. Further, the number of bits of each counter may be different. The same applies to the delay counter 111d, which is not limited to the 4-bit configuration, and may be an 8-bit configuration or a 16-bit configuration. However, when the number of bits of the delay counter 111d is increased, the delay time becomes longer by that amount. Therefore, in such a case, it is desirable to take measures such as increasing the number of places where the delay counter 111d is subtracted in the timer interrupt process.

(18) In the above embodiment, the values of the first counter 111a, the second counter 111b, and the delay counter 111d are not cleared (initialized) even when the RAM is cleared. Is also good.

(19) In the above embodiment, the basic random number generator 150 is provided outside the CPU 102, but the CPU 102 may be built in.

(20) The basic random number generator 150 in the above embodiment latches the count value at the timing when the latch signal from the CPU 102 is input, and outputs the latched count value to the CPU 102. However, such a configuration is changed. To do. For example, the basic random number generator 150 is configured to constantly output the count value of the counter 150a via the latch circuit 150b. That is, the CPU 102 is configured to constantly input the count value of the counter 150a. Then, when the delay time elapses, the CPU 102 latches the count value of the counter 150a input to the CPU 102 at that time and acquires it as a basic random number. Even in the case of such a configuration, it is clear that the same action and effect as those of the above-described embodiment are obtained.

(21) In the above embodiment, the monitoring circuit 152 composed of the D flip-flop circuit is provided, but the monitoring circuit composed of the sequential circuit such as the RS flip-flop circuit and the JK flip-flop circuit and various logic circuits. May be provided.

(22) In the above embodiment, the Q bar terminal of the monitoring circuit 152 is connected to the CPU 102, and the CPU 102 recognizes the L level output signal output from the Q bar terminal as a start signal. It is clear that even if the CPU 102 is connected via the reversing device, the same operation and effect as those of the above-described embodiment can be obtained. Further, if the CPU 102 recognizes the H level output signal as a start signal, the Q terminal and the CPU 102 may be connected, or the Q bar terminal and the CPU 102 may be connected via an inversion device. ..

(23) In the above embodiment, the waveform shaping circuit 153 and the monitoring circuit 152 are connected via the input / output port 104 of the main control device 102, but these are directly connected and the Q of the monitoring circuit 152 is connected. The bar terminal and the CPU 102 may be connected via an input / output port.

(24) In the above embodiment, a monitoring circuit 152 composed of a D flip-flop circuit is provided to prevent the player or the amusement park from suffering a disadvantage when some abnormality occurs in the second clock circuit 151. Although it was set as a configuration, such a configuration will be changed.

A watchdog timer that constantly monitors whether or not the second clock circuit 151 periodically outputs a second clock signal is connected to the second clock circuit. The watchdog timer is provided with a timer counter that is decremented at predetermined time intervals, and the timer value of the timer counter is set every time the input state of the clock signal changes. The watchdog timer outputs an H-level normal signal when the timer counter is non-zero, and outputs an L-level abnormality occurrence signal when the timer counter is zero. On the output side of the watchdog timer, a logical product circuit for calculating the logical product of the operation signal from the start detection sensor 41a and the input signal from the watchdog timer is provided. Then, the inverting signal obtained by inverting the output signal from the AND circuit by the inverting device is input to the CPU 102.

In this case, if the second clock circuit 151 periodically outputs the second clock signal, the timer value is repeatedly set in the watchdog timer, and the timer counter does not become zero. Therefore, the output signal from the watchdog timer is always at the H level, and the output signal from the AND circuit becomes the operation signal itself from the start detection sensor 41a. Then, when the operation signal is output, the output signal is inverted by the inversion device and input to the CPU 102 as a start signal.

On the other hand, when the output state of the second clock signal has not changed due to an abnormality in the second clock circuit 151, the timer counter becomes zero in the watchdog timer and the output signal becomes the L level. Therefore, the output signal of the AND circuit is always at the L level regardless of whether or not the operation signal is input. Therefore, even if the start lever 41 is operated and the operation signal is output, the start signal is not output from the AND circuit to the CPU 102. As a result, a situation occurs in which the reels 32L, 32M, and 32R do not start rotating even though the start lever 41 is operated, and the player or the game hall indicates that some abnormality has occurred inside the slot machine 10. It is possible to notify the persons concerned of.

A watchdog timer was used to determine whether or not the second clock signal was periodically output from the second clock circuit 151, but instead, the duty ratio of the second clock signal was detected. A duty ratio determination circuit that outputs an L level signal when the duty ratio is not within a predetermined normal range (for example, in the range of 25 to 75%) may be provided.

Generally, the normal second clock signal is a pulse signal having a duty ratio of 50%. On the other hand, when the output state of the second clock signal does not change due to some abnormality occurring in the second clock circuit 151, the duty ratio is 0% (in the case of constant or high impedance at the L level). ) Or 100% (when the H level is constant). Therefore, it is possible to determine whether or not the second clock signal is periodically output by determining whether or not the actual duty ratio is within the normal range. In this configuration, when the output state of the second clock signal has not changed, the duty ratio determination circuit outputs the L level signal, so that the output signal of the AND circuit is irrespective of whether or not the operation signal is input. It is always L level. Therefore, even if the start lever 41 is operated and the operation signal is output, the start signal is not output from the AND circuit to the CPU 102.

The normal range of the duty ratio of the second clock signal is not limited to the above example, and may be 10 to 90%, 40 to 80%, or the like, and in short, it may be a range allowed during normal operation. Further, it is not necessary to set the ratio around 50% in the normal operation in contrast, and it may be 10 to 60% or 40 to 90%.

(25) In the above embodiment, the basic random number generator 150 updates the count value of the counter 150a based on the input of the second clock signal, and latches the count value of the counter 150a at the timing when the latch signal is input. Although the configuration is such that the latch is made to 150b, the following configuration may be used.

The latch circuit 150b is configured to be latched after appropriately exchanging the bit array of the count value of the counter 150a.

As an example of such a configuration, a configuration in which the bit array from the lowest to the highest count value of the counter 150a is reversed and latched by the latch circuit 150b can be mentioned as a typical example. In such a configuration, the value latched by the latch circuit 150b changes irregularly with respect to the input of the second clock signal, and it is possible to avoid a problem that the player intentionally acquires a predetermined basic random number. it can.

Further, the bit array of the latched values of the latch circuit 150b may be appropriately exchanged and then output to the CPU 102. Even with such a configuration, it is possible to avoid a problem that the random number input to the CPU 102 changes irregularly with respect to the second clock signal, causing a problem that the player intentionally acquires a predetermined random number. it can.

A plurality of clock circuits that output clock signals of different frequencies are provided, and the count value of the counter 150a is updated based on these clock signals.

In this case, a selection circuit for appropriately selecting which clock circuit to use the clock signal output from is provided, and the clock signal selected by the selection circuit is input to the CLK terminal of the monitoring circuit 152. In such a configuration, since the cycle in which the count value of the counter 150a goes around changes depending on the selection of the clock signal by the selection circuit, it is possible to avoid a problem that the player intentionally acquires a predetermined basic random number.

Instead of the counter 150a, an arithmetic unit whose random number changes each time the input state of the second clock signal changes is provided.

Typical examples of such arithmetic units include those that determine the basic random numbers this time using the basic random numbers up to the previous time, those that generate the basic random numbers by the average picking method, and those that generate the basic random numbers by adding prime numbers. Take as an example. Even in these configurations, since the value latched by the latch circuit 150b changes in a complicated manner based on the change in the input state of the second clock signal, there may be a problem that the player intentionally acquires a predetermined basic random number. It can be avoided.

(26) In the above embodiment, as the clock source of the hardware basic random number generator 150, a second clock circuit 151 for random numbers is provided separately from the first clock circuit 103 for the CPU 102, but the first clock circuit 103 May be used as a clock source. At this time, the clock signal of the first clock circuit 103 may be frequency-modulated (divided, multiplied, etc.). In this case, if the clock signal input to the hardware basic random number generator 150 does not fluctuate due to an abnormality in the circuit unit that performs frequency modulation, the problem that the basic random number is always constant occurs. The abnormality can be found by obtaining the same effect as that of the embodiment.

(27) In the above embodiment, the second clock signal is input to the basic random number generator 150 and the monitoring circuit 152 without modulating the frequency of the second clock signal output from the second clock circuit 151. However, a configuration in which frequency-modulated (divided, multiplied, etc.) is input may be used. Specifically, a converter that performs frequency modulation may be connected to the second clock circuit 151, and the converter may be connected to the basic random number generator 150 and the monitoring circuit 152.

(28) In the above embodiment, it is determined whether or not the start command is generated after three medals have been bet, but the start command is issued even after one bet or two bets. Needless to say, it may be configured to determine whether or not it has occurred. In such a configuration, the slot machine is performed by performing the interrupt waiting process immediately before the process of determining whether or not the credit insertion switch has been operated as in the above embodiment (step S606, see FIG. 19). Can be more preferably avoided from malfunctioning. This is because there may be an opportunity that the game cannot be started with the number of bets desired by the player.

(29) In the above-described embodiment, as the privilege to be granted, in addition to the privilege of shifting the game state and the privilege of re-gaming, the privilege of paying out medals is provided, but the configuration is limited to such a configuration. Rather, the configuration may be such that some privilege is given to the player. For example, a prize other than the medal may be paid out instead of the privilege of paying out the medal. Further, in a slot machine that does not have an actual medal insertion or medal payout function and manages medals owned by a player by credit, an increase in credited medals corresponds to granting a privilege.

(30) In the above embodiment, a slot machine in which three reels are provided in parallel and five lines are provided as effective lines has been described, but the present invention is not limited to this configuration, and for example, five reels are arranged in parallel. It may be a slot machine provided or a slot machine having 7 effective lines.

(31) In the above embodiment, the so-called A type slot machine has been described, but it includes a B type, a C type, an A type and a C type composite type, a B type and a C type composite type, and a CT game. It is clear that the present invention may be applied to any slot machine such as the above-mentioned type, and in any case, the same action and effect as those of the above-described embodiment can be obtained. Examples of the bonus winning in each of these types include BB winning, RB winning, SB winning, and CT winning.

(32) In the above embodiment, a specific example of the slot machine 10 is shown, but it may be applied to a pachinko machine. Further, it may be applied to a gaming machine in which a slot machine and a pachinko machine are fused. That is, among the slot machines, instead of the medal insertion and medal payout functions, a gaming machine having ball throwing and ball payout functions such as a pachinko machine may be used.
