Description

  The present invention relates to a gaming machine such as a slot machine.

  As a kind of gaming machine, there is a rotating type gaming machine, for example, a slot machine. The slot machine is equipped with a plurality of reels with a plurality of symbols, and each player starts rotating by inserting a medal and operating the start lever. After each reel starts rotating, the slot machine stops. Each reel is sequentially stopped by operating the switch or elapse of a predetermined time. In addition, in the slot machine, a winning lottery is performed on the condition that the medal is inserted and the start lever is operated, and the predetermined number of sheets is obtained on the condition that the lottery result is a winning and the winning symbol is stopped on a preset active line. Or a special gaming state (bonus game or the like) advantageous to the player occurs (see, for example, Patent Document 1).

By the way, winning lottery means that, for example, the value of a random number counter updated at a predetermined cycle is acquired at the timing when the start lever is operated, and it is determined whether or not the value corresponds to the winning. Is done by.
JP 2003-126337 A

  However, after identifying the timing corresponding to the winning value in the update cycle of the random number counter, unauthorized actions such as synchronizing the start lever operation timing using a solenoid, low frequency treatment device, etc. The current situation is rampant. When such a fraudulent act is performed, medals are drawn unilaterally, and there is a risk that a hole or a bona fide player will suffer a great deal of damage.

  On the other hand, it is also conceivable that the hall side performs a malicious act of replacing the ROM of the main board with an illegal ROM that reduces the winning probability in the winning lottery. In this case, the number of medals paid out is greatly reduced, and the player may suffer a great deal of damage.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine capable of effectively suppressing fraudulent acts related to the provision of gaming media such as paying out medals.

  In the following, each means suitable for solving the above-mentioned purpose will be described in terms of items. In addition, the effect etc. peculiar to the means to respond | correspond as needed are added.

Means 1. A variable display device for variably displaying the identification information;
An input means for inputting game media at the start of the game;
Starting operation means;
A stop operation means for stopping the variation display of the identification information;
Lottery means for performing the winning lottery of the winning combination triggered by the operation of the start operation means in a state where the game medium is inserted;
The variation display of the identification information is started based on the operation of the start operation unit in a state where the game medium is inserted, and the variation display of the identification information is stopped based on the operation of the stop operation unit and the result of the winning lottery. Identification information control means to be displayed;
A game machine comprising game medium providing means for giving a predetermined game medium when the identification information stopped and displayed by the identification information control means is a combination corresponding to the winning combination,
After the game medium is inserted and the start operation means is operated, the identification information variation display is started. Then, the identification information is stopped and displayed when the stop operation means is operated or a predetermined time elapses. Until one game medium is given according to the combination of identification information
Game number measuring means capable of measuring the number of played games;
An input number recognition means capable of recognizing the number of input game media;
Insertion number storage means for accumulating and storing the number of game media recognized by the input number recognition means;
A given number recognizing means capable of recognizing the number of game media given by the game medium giving means;
Grant number storage means for accumulating and storing the number of game media recognized by the grant number recognition means;
When the number of games measured by the game number measuring means reaches a predetermined number, or when the number of game media accumulated and stored in the input number storage means reaches a predetermined number In addition, based on calculating a ratio of the number of game media accumulated in the given number storage means to the number of game media accumulated in the input number storage means, a game per predetermined target number of games is calculated. A grant rate calculating means for calculating a media grant rate;
It is determined whether at least one of the game medium grant rate calculated by the grant rate calculating means exceeds a preset upper limit threshold and whether the game media grant rate falls below a preset lower limit threshold. A gaming machine comprising a grant rate judging means.

  According to the means 1, the ratio of the total number of granted game media (the number of game media accumulated in the given number storage means) to the total number of entered game media (number of game media accumulated in the entered number storage means) is By calculating, a game medium grant rate (total number of granted game media / total number of input game media) per target number of games is obtained. Then, the calculated game media grant rate is compared with the reference game media grant rate (threshold), and whether the calculated game media grant rate exceeds the upper limit threshold and the lower limit threshold. At least one of the determinations is made as to whether the value is less than. The result of the determination can be used as an index as to whether or not fraud related to the grant of the game medium has been performed. Further, based on the determination result, for example, when the upper limit threshold is exceeded, or the lower limit threshold If it falls below, the fact can be notified or the game can be interrupted. As a result, fraudulent acts relating to the granting of game media can be suppressed.

  In particular, when the game medium grant rate calculated by the grant rate calculation means exceeds the upper limit threshold value, for example, when adopting a configuration in which notification or the like is performed, the act of illegally acquiring the game media by the player Can be suppressed. As a result, it is possible to deter disadvantages that extend to the hall side due to cheating. In addition, if the hall side tries to obtain a certain profit as a whole hall, the loss of illegally drawn game media may be collected from those who play games on other gaming machines (bona fide players) Though conceivable, the above-described configuration can suppress the unexpected disadvantage of a bona fide player.

  On the other hand, when the game medium grant rate calculated by the grant rate calculation means falls below the lower limit threshold value, for example, when adopting a configuration in which notification or the like is performed, it is difficult to acquire game media due to fraudulent acts on the hall side. The situation of doing can be suppressed. In other words, it is possible to suppress an illegal act in which the hall side replaces the regular lottery means with an illegal lottery means in which the winning probability is unreasonably low during the winning lottery.

  In the case where an illegal determination is made on the hall side, there is a concern that concealment may be performed freely on the hall side. In this respect, since this means is configured to determine whether or not the “gaming machine” is cheating, it may be configured so that notification or the like can be executed directly on the gaming machine without going through the hall side. it can. Therefore, the above concerns can be eliminated.

  The “specified number of times” may be changed as appropriate according to the number of game media inserted for each game. For example, the measured value varies depending on the number of game media inserted at the start of the game (for example, when a configuration in which a maximum of three game media can be input per game is adopted, the game media is 3 When one game is inserted, it is counted as one game time, and when one game medium is inserted, it is counted as 1/3 game time).

  In addition, when adopting the case where “the number of games has reached the specified number” as an opportunity to calculate the game medium grant rate, “whether or not the number of games measured by the game number measuring means has reached the specified number of times” The number-of-times determining means for determining On the other hand, when adopting the case where “the number of game media accumulated and stored in the input number storage means reaches a prescribed number” as an opportunity to calculate the game medium grant rate, “the cumulative number is stored in the input number storage means. The game medium number determination means for determining whether or not the number of game media that have reached the specified number may be provided. Further, when the latter configuration is adopted, the game frequency measuring means can be omitted.

  Further, as a setting method of the “threshold value”, a distribution range of game medium grant rates that can be taken when the target number of games is played is calculated in advance, and an upper limit of the game media grant rate is calculated based on the distribution range. It is desirable to set at least one of the value and the lower limit value as a threshold value in advance. Further, in this case, a threshold storage unit that stores the preset threshold may be provided.

  In addition, the “throwing-in means” refers to a slot for inserting a game medium from the outside, and in the case where the game medium is configured to be stored and stored as a virtual game medium, The meaning of a loading operation means for loading a medium is included. In this case, the number-of-insertions storage means cumulatively stores the number of game media inserted from the insertion slot and the number of game media input by operating the input operation means. Further, the number-of-grant storage means stores and stores the number of game media actually given (paid out) based on the fact that the identification information is stopped and displayed in a combination corresponding to the winning combination. Both the numbers of game media are accumulated and stored (hereinafter the same for each means).

In other words, if the number of game media accumulated in the normal game state and the number of game media accumulated in the special game state are collectively collected without distinguishing, the threshold value serving as a reference is set. There is concern that it must be set roughly.

  In this regard, in the present means 2, the number of input game media and the number of game media to be awarded in the normal game state are individually accumulated and stored, and the game media grant rate only in the normal game state is calculated. For this reason, it is not necessary to consider the increase / decrease of game media in the special game state, and a more accurate threshold value corresponding to the normal game state can be set.

  Each of the reels 42L, 42M, and 42R is connected to stepping motors 61L, 61M, and 61R as driving means, and each of the reels 42L, 42M, and 42R is individually driven by the driving of the stepping motors 61L, 61M, and 61R. In other words, each of them can be independently driven to rotate. Since these reels 42L, 42M, and 42R have the same configuration, here, the left reel 42L will be described as an example with reference to FIG. FIG. 6 is an assembled perspective view of the left reel 42L.

  The left reel 42L includes a cylindrical skeleton member 50 that forms a cylindrical cage, and a belt-like belt wound endlessly on the outer peripheral surface thereof. And it is affixed on the cylindrical skeleton member 50 through a pair of seal parts formed along the both sides of the long side of the belt so as to maintain the wound state. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt. A boss portion 51 constituting a support shaft portion is formed at the center of the cylindrical skeleton member 50, and is attached to the drive shaft of the left reel stepping motor 61L via a disk-like boss reinforcing plate 52. Accordingly, when the drive shaft of the left reel stepping motor 61L is rotated, the cylindrical skeleton member 50 is rotated around the drive shaft so that the left reel 42L circulates along the annular reel surface. It has become.

  The left reel stepping motor 61L is fixed to the side surface of the motor plate 53 arranged in an upright state in the reel unit 41 (FIG. 3) with screws 54. The motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 as detection means at a predetermined detection position. In the present embodiment, as the reel index sensor 55, a transmissive photosensor in which a light emitting element 55a as a light emitting unit and a light receiving element 55b as a light receiving unit are held at a predetermined interval is employed.

  On the other hand, a sensor cut bun 56 extending in the radial direction is attached to the boss reinforcing plate 52 integrated with the left reel 42L. The sensor cut bun 56 has a base end portion 56 b fixed by a screw 58. The front end portion of the sensor cut bun 56 is bent at a substantially right angle, and the front end portion is formed with a protrusion 56a as a first detected portion that protrudes along the rotation axis direction of the left reel 42L. The sensor cut bun 56 is aligned so that the protrusion 56a can pass between both elements 55a and 55b of the reel index sensor 55. The reel index sensor 55 detects the passage of the protrusion 56a every time the left reel 42L makes one round, and a detection signal is output to the main controller 131 described later each time the detection is made. The reel index sensor 55 is configured to perform the detection periodically (for example, at a cycle of 1.49 msec). Therefore, the main controller 131 can check and correct the rotation position (rotation angle position) of the left reel 42L almost every round based on this detection signal.

  The stepping motor 61L is set to rotate once by giving, for example, a drive signal of 504 pulses (also referred to as an excitation signal or an excitation pulse; the same applies hereinafter). That is, the left reel 42L is rotated by a rotation amount corresponding to the number of drive signals, such that the left reel 42L changes by an angle of 5 ° with a 7-pulse drive signal. Further, the rotational position of the stepping motor 61L, that is, the rotational position of the left reel 42L is controlled by this drive signal.

  As will be described in detail later, in the present embodiment, 21 symbols are drawn on the belts of the reels 42L, 42M, and 42R in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses ÷ 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Then, depending on the number of pulses from the time when the rotational position of the left reel 42L is detected (for example, when the start end 56s of the sensor cut bun 56 (projecting portion 56a) is detected), which symbol is visible from the display window 31L. It can be controlled to recognize whether it is in a state or to make an arbitrary symbol visible from the display window 31L.

  Here, the symbols attached to the reels 42L, 42M, and 42R will be described. FIG. 7 shows a symbol arrangement drawn on the belt wound around each of the left reel 42L, the middle reel 42M, and the right reel 42R. As shown in the figure, each of the reels 42L, 42M, and 42R is provided with 21 symbols in a row. Although numbers 1 to 21 are assigned to the respective reels 42L, 42M, and 42R, these are given for convenience of explanation, and are not actually attached to the reels 42L, 42M, and 42R. . However, in the following description, the number is used for explanation. Of the symbols attached to each of the reels 42L, 42M, and 42R, the number of symbols that can be visually recognized through the display windows 31L, 31M, and 31R is mainly the vertical length of the display windows 31L, 31M, and 31R. Is limited to a predetermined number determined by In this embodiment, three reels are provided. For this reason, when all the reels 42L, 42M, and 42R are stopped, 3 × 3 = 9 symbols are visible to the player.

  As a symbol, there are a “red 7” symbol (for example, the 14th left belt) and a “blue 7” symbol (for example, the 20th left belt) as the first special symbol for shifting to the big bonus game. . Further, there is a “BAR” symbol (for example, the 18th left belt) as the second special symbol for shifting to the regular bonus game. In addition, there is a “replay” symbol (for example, the 21st left belt) as a third special symbol for shifting to the replay game. Also, the “watermelon” symbol (for example, the left belt 17th), the “bell” symbol (for example, the left belt 16th), the “cherry” symbol (for example, the left), Belt 19th). As shown in FIG. 7, the number of various symbols and the arrangement order are completely different in the belt wound around each reel 42L, 42M, 42R.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of a variable display device that variably displays identification information, and constitutes a main display unit.

  A total of five combination lines are attached to the game panel 30 such that three display windows 31L, 31M, and 31R are connected to each other and three in parallel in the horizontal direction and two in diagonal directions. Of course, the maximum number of combined lines may be 6 or more, or less than 5, and the maximum number of combined lines may be changed according to a predetermined condition. Corresponding to these combination lines, effective line display sections 32, 33, and 34 are provided on the left side when viewed from the front of the display windows 31L, 31M, and 31R. The first effective line display unit 32 is notified by lighting or the like when the central horizontal line (center line) of the combination lines is activated. When the upper and lower horizontal lines (upper line and lower line) of the combination lines are activated, the second effective line display unit 33 is displayed and notified by lighting or the like. The third effective line display unit 34 is notified by lighting or the like when a pair of diagonal lines (downward right line and upward right line) of the combination lines is activated. A winning is awarded when the symbols are stopped in a predetermined combination on the activated combination line, that is, on the activated line, and a predetermined medal payout process, a transition process to a specific game, and the like are executed.

  Here, the payout number regarding each symbol when winning is explained. Regarding the small role design, when the “Watermelon” design is aligned with the left, middle and right on the active line, 15 medals are paid out. When the “Bell” design is aligned with the left, middle and right on the effective line Pays out 10 medals, and when the “cherry” symbol on the left reel 42L stops on the active line, 2 medals are paid out. That is, the “cherry” symbols of the middle reel 42M and the right reel 42R are irrelevant to the medal payout. In addition, for the “cherry” symbol, medals are paid out regardless of the combination with other symbols, and therefore, a plurality of effective lines of the left reel 42L overlap (specifically, the upper or lower row) with “ When the “cherry” symbol is stopped, medals are paid out by multiplying the number of overlapping active lines. As a result, in this embodiment, four medals are paid out. In the present embodiment, medals correspond to game media.

  For other symbols, the combination of the first special symbol (Big Bonus symbol) “Red 7” symbol or “Blue 7” symbol is aligned with the left, middle and right on the active line in the same symbol In the case of “BAR” symbol which is a combination of 15 medal payouts and the second special symbol (regular bonus symbol), 15 medal payouts are also made when left, middle and right are aligned on the active line. In the present embodiment, for example, a case where the “red 7” symbol and the “cherry” symbol are simultaneously established (internal winning) may occur, but in this case, 15 medals are paid out. This is because the upper limit number for one medal payout is set to 15.

  Further, when the “replay” symbol, which is the combination of the third special symbol, is aligned with the left, middle, and right on the active line, the medal payout is not performed. Instead, when starting the next game, the next game can be played free of charge under the same conditions as the current game. In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the same symbols as the left, middle, and right are not aligned on the active line, no medal payout is performed.

  On the lower left side of the game panel 30, a start lever 71 is provided that is operated to start rotation of the reels 42L, 42M, and 42R all at once (not necessarily simultaneously). The start lever 71 constitutes start operation means operated to start rotation of the reels 42L, 42M, and 42R, that is, to start variable display. The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the original position after the hand is released. When the start lever 71 is operated while a medal is inserted, the reels 42L, 42M, and 42R start to rotate all at once.

  On the right side of the start lever 71, button-like stop switches 72, 73, 74 that are operated to individually stop the rotating reels 42L, 42M, 42R are provided. Each of the stop switches 72, 73, 74 is arranged directly below the display windows 31L, 31M, 31R corresponding to the reels 42L, 42M, 42R to be stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop variable display based on the rotation of the reels 42L, 42M, 42R. Each of the stop switches 72, 73, 74 can be stopped when a predetermined time elapses after the left reel 42L starts rotating, and is stopped by lighting a lamp (not shown) during such a state. It is notified that the operation is possible, and is turned off when the rotation stops.

  On the lower right side of the display windows 31L, 31M, 31R, there is provided a medal slot 75 for inserting medals as game media.

  The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by a selector 84 as a variable means provided on the back surface of the front door 12. That is, the selector 84 is provided with a medal path switching solenoid 83, which is set to the discharge path 82 side when the medal path switching solenoid 83 is not excited, and switched to the storage path 81 side when excited. The medal guided to the storage passage 81 is guided to the hopper device 91 housed inside the housing 11. On the other hand, the medal guided to the discharge passage 82 is guided to the medal tray 18 from the medal discharge port 17 provided in the lower front portion of the front door 12 and returned to the player.

  The hopper device 91 that grants medals to a player includes a storage tank 92 that stores medals and a payout device 93 that pays out medals to the player. The payout device 93 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 94 provided in the central right part of the discharge passage 82 and to the medal tray 18 through the discharge passage 82. To come out. Further, a reserve tank 95 is provided on the right side of the hopper device 91 in order to avoid storing a predetermined amount or more of medals in the storage tank 92. A guide plate 96 for discharging medals from the storage tank 92 to the reserve tank 95 is provided inside the storage tank 92 of the hopper device 91. Therefore, when medals are stored more than the height at which the guide plate 96 is provided, the medals are stored in the reserve tank 95.

  A button-like return switch 76 is provided below the medal slot 75. The return switch 76 is a switch that is pressed when a medal inserted into the medal slot 75 is jammed in the selector 84. When this switch is pressed, the selector 84 is mechanically operated to operate the selector 84. The medals packed in 84 are returned from the medal discharge port 17.

  On the lower left side of the display windows 31L, 31M, and 31R, a button shape for inserting (maximum bed) the maximum number (three) of medals that can be inserted per game among the virtual medals that are credited (stored and stored) at a time. The first credit input switch 77 is provided. Further, on the left side of the first credit insertion switch 77, a button-like credit insertion switch 78 is provided which is smaller than the switch 77 for inserting the credited virtual medals one by one.

  The first credit insertion switch 77 has a built-in lamp as a light emitting member (not shown) to urge that the maximum number of medals that can be inserted per game (three) has not been reached. The lamp is turned on when the switch operation of the first credit insertion switch 77 is valid and prompts the operation of the switch 77. However, when there is no credited virtual medal or three medals have already been inserted. It is turned off under the circumstances. Here, instead of the above-described lighting, the player may make it easier to understand the prompt for medal insertion by blinking.

  A button-like changeover switch 80 is provided on the left side of the start lever 71. The changeover switch 80 is configured to be turned on when pressed once, turned off when pressed again, and switched on and off every time a pressing operation is performed thereafter. The changeover switch 80 is operated to change the handling format of inserted medals inserted into the medal slot 75 more than necessary, or acquired medals returned to the player as a result of a predetermined game.

  When the change-over switch 80 is in the ON state, the “credit mode” is set so that surplus inserted medals up to a predetermined maximum value (for example, 50 medals) and winning medals are stored and stored as credit medals. " When the changeover switch 80 is in the OFF state, the “direct mode” is set so that surplus inserted medals and winning medals are paid out as actual medals. If there is a credit medal when the credit mode is switched to the direct mode, the corresponding credit medal is paid out as an actual medal. Thus, the player can execute the game in a format according to his / her preference by switching between the credit mode and the direct mode. The changeover switch 80 constitutes a changeover operation means for changing the input value and the handling format of the game media. Further, if attention is paid to the function of paying out a credited virtual medal as an actual medal, it can be said that the changeover switch 80 constitutes a settlement operation means for actually paying out the stored and stored game media. In addition to being configured to switch between the “credit mode” and the “direct mode” by operating the changeover switch 80, the virtual medal stored and stored is paid out when the changeover switch 80 is operated by always setting the “credit mode”. It may be made to function as only a settlement switch.

  Below the display windows 31L, 31M, 31R of the gaming panel 30, there are a remaining number display section 35 for displaying the number of medals activated and stored in the credit mode, and in a special gaming state such as a big bonus or a regular bonus. For example, a game number display unit 36 for displaying the number of remaining games and an acquired number display unit 37 for displaying the number of acquired medals are provided. Although these display parts 35-37 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, a procedure for betting medals will be described. In both the direct mode and the credit mode, a bet is placed when a medal is inserted from the medal slot 75 at the start of the game.

  That is, when the first medal is inserted into the medal insertion slot 75, the first effective line display section 32 is turned on, and the corresponding center line becomes the effective line, and the second medal is the medal insertion slot. When the number 75 is inserted, the second effective line display section 33 is turned on, and a total of three combination lines including the upper line and the lower line corresponding to the second effective line display section 33 become effective lines, respectively, and the third medal is a medal. When it is inserted into the insertion port 75, the third effective line display unit 34 is further turned on, and a total of five combination lines including a pair of diagonal lines corresponding thereto become effective lines.

  When four or more medals are inserted into the medal slot 75, the surplus medals exceeding three are switched to the discharge passage 82 by the selector 84 if the current mode is the direct mode. It is returned from the outlet 17 to the medal tray 18. On the other hand, in the credit mode, it is stored inside the slot machine, and the number of stored sheets is displayed on the remaining number display unit 35. An upper limit number is determined for the number of stored sheets (for example, 50), and when more medals are inserted, they are returned to the medal tray 18 from the medal outlet 17.

  In addition, when a game is played in the credit mode and the remaining number display unit 35 displays the stored number, the virtual medal is inserted when either of the credit insertion switches 77 and 78 is pressed. It becomes a bet.

  When the second credit insertion switch 78 is pressed, the numerical value displayed on the remaining number display section 35 is decremented by one as a virtual medal is inserted, and the first effective line display section 32 is displayed. Illuminates and the center line becomes the active line. Further, when the second credit insertion switch 78 is pressed in a state where the central line is an active line, the numerical value displayed on the remaining number display unit 35 is that one more virtual medal has been inserted. One is decremented, the second effective line display section 33 is lit, and a total of three combination lines become effective lines. Further, when the second credit insertion switch 78 is pressed with the first and second effective lines 32 and 33 lit, or when the first credit insertion switch 77 is pressed, three virtual medals are obtained. The number displayed on the remaining number display part 35 is decremented by three as having been inserted, all the effective line display parts 32 to 34 are lit, and a total of five combination lines become effective lines. The slot machine 10 according to the present embodiment is a so-called three-seat dedicated machine that allows the start of a game when three medals are bet (max bet), and usually five combination lines are effective lines. The game is played in the state. In the case of a JAC game described later, one medal is bet.

  Further, when the virtual medal to be inserted is not stored when the first credit insertion switch 77 is pressed, for example, the first credit insertion switch 77 is pressed when the display of the remaining number display unit 35 is 2. In some cases, all the numerical values in the remaining number display section 35 are decremented to 0, and a bet is placed for the amount of virtual medals that can be inserted.

  The reset switch 123 is a switch for resetting various states of the slot machine 10. This slot machine 10 has a backup function for various data. Even if a power failure occurs, the slot machine 10 maintains the state at the time of the power failure, and returns to the state at the time of the power failure at the time of recovery from the power failure (power recovery). It can be done. Therefore, for example, when the power supply is shut down by a normal procedure, such as when the game hall is closed, the state before the power shut-off is stored, but if the power switch 122 is turned on while pressing the reset switch 123, the backup data is reset. It has become so. If the reset switch 123 is pressed while the power switch 122 is on, the error state is reset.

  The setting key insertion hole 124 is used by a hole manager or the like to adjust the appearance of medals. That is, the setting state (winning probability setting process) of the slot machine 10 can be changed from “setting 1” to “setting 6” by operating the hole manager or the like by inserting the setting key into the setting key insertion hole 124. It has become.

  A main control device 131 is attached to the back plate 11 c of the housing 11 above the reel unit 41. The main control device 131 includes a CPU that controls the main control, a ROM that stores a game program, a RAM that temporarily stores necessary data according to the progress of the game, a port that communicates with various devices, time counting and synchronization. A main board including a clock circuit and the like used in the case of planning is provided, and the main board is accommodated in a board box as an encapsulating means made of a transparent resin material or the like. The board box includes a substantially rectangular parallelepiped box base and a box cover that covers an opening of the box base. The box base and the box cover are connected to each other so as not to be opened by a sealing unit as a sealing means, whereby the substrate box is sealed. In addition, it is good also as a structure which connects a box base and a box cover so that opening is impossible using a key member.

  Next, the electrical configuration of the slot machine 10 will be described based on the block diagram of FIG.

  The main control device 131 is equipped with a microcomputer centering on a CPU 151 as arithmetic processing means. In addition to the power supply device 161 as a power supply means provided in the power supply box 121, the CPU 151 is connected to a clock circuit 154 that outputs a rectangular wave with a predetermined frequency, an input / output port 155, and the like via an internal bus. ing. The main control device 131 functions as a main board built in the slot machine 10. In the present embodiment, the main control device 131 constitutes main control means, lottery means, identification information control means, game medium giving means, special game state giving means, throwing number recognition means, given number recognition means, and game state determination means. .

  On the input side of the main controller 131, there are a start detection sensor 71a for detecting the operation of the start lever 71, stop detection sensors 72a, 73a, 74a for individually detecting the operations of the stop switches 72, 73, 74, and a medal slot. Inserted medal detection sensor 75a for detecting a medal inserted from 75, credit insertion detection sensors 77a and 78a for individually detecting the operations of the respective credit insertion switches 77 and 78, a switching detection sensor 80a for detecting the operation of the changeover switch 80, A reel index sensor 55 that individually detects the rotational position of each reel 42, a payout detection sensor 91 a that detects medals paid out from the hopper device 91, a reset detection sensor 123 a that detects the operation of the reset switch 123, and a setting key insertion hole 124. Detects that a setting key has been inserted That setting key detection sensor 124a sensors are connected, such as, signals from these various sensors are outputted to the CPU151 through the input-output port 155.

  The inserted medal detection sensor 75a is actually composed of a plurality of sensors. That is, the storage passage 81 extending from the medal insertion slot 75 to the hopper device 91 is configured such that medals can pass in one row. The storage passage 81 is provided with a first sensor, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal. The inserted medal detection sensor 75a is constituted by each of the first to third sensors. The main control device 131 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, the main control device 131 considers that there has been a medal clogging or fraud and makes an error. If an error occurs, an error notification is performed and an operation by the player until the error is canceled is invalidated. The main controller 131 also monitors the order in which the second sensor and the third sensor are turned on and off, both the second and third sensors are off, only the second sensor is on, and both the second and third sensors are on. Only when the third sensor is turned on, both the second and third sensors are turned off, and when the time for switching to each on / off switching is within a predetermined time, it is determined that the medal has been normally taken in. Otherwise, an error is assumed. The reason for this is to prevent injustice that the medal is reciprocated in the vicinity of the inserted medal detection sensor 75a and misidentified as the medal inserted in addition to the clogging of the medal in the storage passage 81.

  Further, a power failure monitoring circuit 161 b provided in the power supply device 161 is connected to the input side of the main control device 131 via the input / output port 155. Furthermore, in this embodiment, the power failure monitoring circuit 161b and the display control device 111 are connected.

  The power failure monitoring circuit 161b is for monitoring the power-off state and generating a power failure signal not only at the time of power failure but also at the time of power-off by the power switch 122. Therefore, the power failure monitoring circuit 161b is output from the power supply unit 161a. In this example, a stabilized driving voltage of DC 12 volts is monitored, and when this driving voltage drops below, for example, 10 volts, it is determined that the voltage has been cut off and a power failure signal is output. The power failure signal is supplied to each of the CPU 151 and the input / output port 155, and the CPU 151 recognizes this power failure signal and executes a power failure process described later. In the present embodiment, a power failure signal is also supplied to the display control device 111, and the display control device 111 (CPU 181) recognizes this power failure signal to perform a display power failure processing described later. Executed.

  The power supply unit 161a is configured to output a stabilized voltage of 5 volts used as a drive voltage in a control system such as the main control device 131 and the display control device 111 even when the output voltage is reduced to less than 10 volts. As the time during which the stabilized voltage is output, sufficient time is secured to execute the power failure process by the main controller 131 and the display power failure process by the display controller 111.

  On the output side of the main control device 131, each active line display section 32, 33, 34, remaining number display section 35, game number display section 36, acquired number display section 37, and each reel 42L, 42M, 42R are rotated. Stepping motors 61 (61L, 61M, 61R), a medal path switching solenoid 83 provided in the selector 84, a hopper device 91, a display control device 111, an external concentration terminal plate 171 capable of transmitting information to a hall management device (not shown), etc. Are connected via the input / output port 155.

  The display control device 111 is a control device for driving the upper lamp 13, the speaker 14, and the auxiliary display unit 15, and includes a substrate in which a CPU 181, a ROM 182, a RAM 183, and the like for driving these are integrated. Then, after receiving a signal from the main control device 131, the display control device 111 independently drives and controls the upper lamp 13, the speaker 14, and the auxiliary display unit 15. Therefore, the display control device 111 is a sub-board that performs auxiliary control in relation to the main control device 131 that is a main board that manages and manages games. In other words, a sub-board is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main board. The display control device 111 is also housed in a sealed state in a substrate box having a box base and a box cover, as with the main control device 131. In addition, it is good also as a structure which the display control apparatus 111 controls the various display parts 32-37.

  The CPU 151 described above stores various control programs executed by the CPU 151 and a ROM 152 storing fixed value data, and temporarily stores various data when the control program stored in the ROM 152 is executed. A RAM 153 for securing an area is incorporated. In addition, although not shown, as is well known, various processing circuits required in the slot machine 10 such as an interrupt circuit, a timer circuit, a data transmission / reception circuit, a credit counter for counting the number of credits, and the number of detections by the inserted medal detection sensor 75a Various counters such as an insertion number counter for counting the number of times and a payout number counter for counting the number of times of detection by the payout detection sensor 91a are incorporated. A main memory is configured by the ROM 152 and the RAM 153, and a program for executing the processing shown in various flowcharts shown in FIG. 9 and subsequent figures is stored in the ROM 152 described above as a part of the control program.

  The RAM 153 has a configuration in which a backup voltage is supplied from the power supply device 161 provided in the power supply box 121 and data can be held (backed up) even after the power of the slot machine 10 is cut off. In addition to a memory and an area for temporarily storing various data and the like, a backup area is provided. In the present embodiment, the backup voltage is also supplied from the power supply device 161 to the RAM 183 of the display control device 111, so that data can be retained even after the power to the slot machine 10 is shut off.

  In the backup area, when the power is shut down due to the occurrence of a power failure or the like, the values of the stack pointer, each register, I / O, etc. when the power is shut down (including power shut down by operating the power switch 122; the same applies hereinafter) When the power failure is resolved (including power-on by operating the power switch 122. The same applies hereinafter), the slot machine 10 is in the state before power-off based on the backup area information. It is possible to return to the state. Writing to the backup area is executed when the power is shut off by the power failure process (see FIG. 11), and the restoration of each value written in the backup area is executed in the main process (see FIG. 13) when the power is turned on. Note that a power failure signal from the power failure monitoring circuit 161b is input to the NMI terminal (non-maskable interrupt terminal) of the CPU 151 when the power is interrupted due to the occurrence of a power failure or the like. NMI interrupt processing as flag generation processing is immediately executed. Further, in the present embodiment, also in the display control device 111, when a power failure signal is input, a display NMI interrupt process as a power failure flag generation process associated with the occurrence of a power failure or the like is immediately executed.

  Subsequently, each control process executed by the CPU 151 in the main controller 131 will be described with reference to the flowcharts of FIGS. The processing of the CPU 151 is roughly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in this embodiment, at a cycle of 1.49 msec), and an NMI terminal (non-maskable terminal). There is an NMI interrupt process activated by the input of a power failure signal. For convenience of explanation, the NMI interrupt process and the timer interrupt process will be described first, and then the main process will be described.

  FIG. 9 is a flowchart showing an example of the NMI interrupt process. When the power is shut off due to the occurrence of a power failure or the like, the power failure monitoring circuit 161b of the power supply device 161 generates a power failure signal and outputs it to the main controller 131. In the main controller 131 that has received the power failure signal via the NMI terminal, NMI interrupt processing is executed.

  In the NMI interrupt processing, first, in step S 101, the data of the used register provided in the CPU 151 is saved in the backup area provided in the RAM 153. Subsequently, in step S102, the power failure flag is set in a power failure flag storage area provided in the RAM 153. Thereafter, the data saved in the backup area of the RAM 153 in step S103 is restored to the use register of the CPU 151 again. With this return processing, the NMI interrupt processing ends. If the power failure flag can be set without destroying the data in the register used by the CPU 151, the saving and restoring processing to the backup area can be omitted.

  FIG. 10 is a flowchart of a timer interrupt process periodically executed by the main controller 131. A timer interrupt is generated by the CPU 151 of the main controller 131 every 1.49 msec, for example.

  First, in the register saving process shown in step S201, the values of all the registers in the CPU 151 used in the normal process described later are saved in the backup area of the RAM 153. In step S202, it is confirmed whether or not a power failure flag is set. If the power failure flag is set, the process proceeds to step S203, and a power failure process is executed.

  Here, the power failure process will be described with reference to FIG. Since the power failure process is performed immediately after the register saving process in the timer interrupt process, other interrupt processes can be executed without interruption. Therefore, for example, during the process of transmitting various commands, during the process of reading the switch state (on / off), the process at the time of power failure is not executed by interrupting each process. It is no longer necessary to create a power failure processing program that also takes into account This simplifies the processing program for power failure processing and reduces the program procedure. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether or not transmission of a command and medal information described later has been completed. If the transmission has not been completed, the present process is terminated and the process returns to the timer interrupt process, and the transmission of the command and medal information is terminated. In this way, it is determined whether or not the transmission of the command and medal information is completed at the initial stage of the power failure process. When the transmission is not completed, the transmission process is given priority. By adopting the configuration to execute, it is not necessary to construct a power failure processing program that takes into account that power failure processing is executed during command transmission. As a result, the power failure processing program can be simplified and the ROM 152 can be reduced in capacity.

  If step S301 is YES, that is, if the command transmission is completed, the process proceeds to step S302, and the value of the stack point of the CPU 151 is stored in the backup area in the RAM 153. Thereafter, in step S303, a RAM determination value, which will be described later, is cleared as a stop process and the output state of the output port in the input / output port 155 is cleared, and all actuators (not shown) are turned off. In step S304, a RAM determination value is calculated and stored in the backup area. The RAM determination value is specifically a 2's complement of the checksum at the work area address of the RAM 153. By storing the RAM determination value in the backup area, the checksum of the RAM 153 becomes zero. By setting the checksum of the RAM 153 to 0, subsequent RAM access is prohibited in step S305. After that, an infinite loop is entered in preparation for the case where the power supply is completely shut down and processing cannot be executed. In consideration of, for example, a case where the power failure flag is erroneously set due to noise or the like, it is confirmed whether or not a power failure signal is output until the infinite loop is entered. If the power failure signal is not output, the power failure state is restored, so that writing to the RAM 153 is permitted, the power failure flag is reset, and the process returns to the timer interrupt process. If the power outage signal is continuously output, the infinite loop is entered.

  The power supply unit 161a of the power supply device 161 holds the output of the stabilization voltage (5 volts) used as the drive voltage for the control system for a time sufficient to execute the above-described NMI interrupt processing and power failure processing. It is comprised so that. In the present embodiment, the drive voltage is continuously output for 30 msec.

  Returning to the description of the timer interrupt process, if the power failure flag is not set in step S202, various processes after step S204 are performed.

  That is, in step S204, a watchdog timer clearing process for initializing the value of the watchdog timer for monitoring the occurrence of malfunction is performed. In step S205, an interrupt end declaration process for giving an interrupt permission to the CPU 151 itself is performed. In step S206, in order to rotate the reels 42L, 42M, and 42R, stepping motor control processing for driving the stepping motors 61L to 61R that are the respective rotation driving motors is performed.

  In step S207, sensor monitoring processing is performed to monitor the state of various sensors (see FIG. 8) connected to the input / output port 155.

  In step S208, arithmetic processing for subtracting the value of the counter (random number counter) or timer is performed.

  In step S209, counter processing is performed to output the result of counting the number of inserted medals and the number of paid out medals to the external concentrated terminal board 171.

  In step S210, command output processing for transmitting a command to the display control device 111 is performed. In addition, the display control apparatus 45 which input the command transmitted from the main control apparatus 131 determines the production | presentation aspect of the upper lamp 13, the speaker 14, and the auxiliary | assistant display part 15 based on the command, and this production | generation aspect is used as an upper lamp. 13, the speaker 14, and the auxiliary display unit 15.

  In step S <b> 211, medal information output processing is performed for transmitting information (medal information) on medal betting and medal payout to the display control device 111. As will be described in detail later, the medal information transmitted to the display control device 111 in the medal information output process is stored in the display control device 111.

  Here, the medal information output processing will be described with reference to FIG. Details of the big bonus game and JAC game described in the medal information output process will be described later.

  First, in step S1101, it is determined whether or not a big bonus (BB) game is in progress. If it is determined that the BB game is being played, it is determined in step S1102 whether or not the JAC game is being played. If it is determined that the JAC game is in progress, this process is terminated. On the other hand, if it is determined that the JAC game is not being played (if it is a small role game in the BB game), the process advances to step S1103 to perform a BB game bet information output process.

  In the BB game bet information output process in step S1103, if there is information on the number of medals bet, the information is transmitted to the display control device 111 as medal information in the BB game (BB game bet medal information). . More specifically, the number of medals betted when a medal is inserted into the medal insertion slot 75 or the credit insertion switches 77 and 78 are operated, that is, the number of medals bet when starting a game is displayed on the display control device 111. Sent. In the present embodiment, information on the number of medals that are automatically inserted upon establishment of a replay combination is transmitted to the display control device 111 as being bet.

  Next, in step S1104, BB game payout information output processing is performed. Here, if there is information on the number of medals that have been paid out, the information is transmitted to the display control device 111 as medal information in the BB game (BB game payout medal information). More specifically, the number of medals to be paid out based on the fact that the winning combination is established on the active line, that is, the number of medals acquired by the player is transmitted to the display control device 111. In the present embodiment, even when a replay combination is established, it is assumed that the number of medals equal to the number of medals bet on the current game (three in this example) has been paid out, and the number information is sent to the display control device 111. It is supposed to be sent. Then, after the payout information in the BB game is transmitted, this process is terminated.

  On the other hand, if it is determined in step S1101 that the BB game is not being played, the process proceeds to step S1105, where it is determined whether or not a regular bonus (RB) game is being played. If it is neither the BB game nor the RB game, that is, the normal game, the process proceeds to step S1106, and the normal game bet information output process is performed. On the other hand, if it is determined that the RB game is being played, this processing is terminated as it is.

  In the normal game bet information output process in step S1106, if there is information on the number of medals bet, the information is transmitted to the display control device 111 as medal information in the normal game (normal game bet medal information). . Next, in step S1107, after performing the payout information output process during the normal game, this process ends. In the normal game bet information output process, when there is information on the number of medals paid out, the information is transmitted to the display control device 111 as medal information in the normal game (ordinary payout medal information).

  Returning to the description of the timer interrupt process, in step S212, a segment data setting process for setting the segment data displayed on the remaining number display unit 35, the game number display unit 36, and the acquired number display unit 37 is performed. In step S213, the segment data set processing in the segment data setting processing is supplied to the display units 35 to 37, and the segment data display processing for displaying the corresponding numbers, symbols, etc. is performed. In step S214, port output processing for outputting data corresponding to the I / O device from the input / output port 155 is performed. In step S215, the value of each register saved in the backup area in the previous step S201 is restored to the corresponding register in the CPU 151. Thereafter, in step S216, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  FIG. 13 is a flowchart showing a main process in the main controller 131 that is executed after the power is turned on. The main process is executed when the power is turned on by recovery from a power failure or by turning on the power switch 122.

  First, in step S401, as initialization processing, the value of the stack pointer is set in the CPU 151, and an interrupt mode that permits interrupt processing is set. Thereafter, various settings for the register group in the CPU 151, the I / O device, and the like are set. And so on.

  When these initialization processes are completed, it is next determined in step S402 whether or not the reset switch 123 has been turned on. If the reset switch 123 has been turned on, the process proceeds to step S403, and all data stored in the RAM 153 is cleared as a RAM clear process.

  After confirming that the reset switch has not been operated in step S402 or performing a RAM clear process in step S403, it is determined in step S404 whether or not a setting key has been inserted into the setting key insertion hole 124. To do. If the setting key has been inserted, the process proceeds to step S405 to perform setting change processing. As the setting change process, first, all data stored in the RAM 153 is cleared. Then, after determining which setting state is selected from the six preset setting states (“Setting 1” to “Setting 6”), internal processing corresponding to the selected setting state is executed. .

  In step S406, it is confirmed whether or not a power failure flag is set. If the power failure flag is not set, that is, if the data in the RAM 153 has been cleared in step S403 or step S405, the process proceeds to a normal process in step S407, which will be described later, and this process is terminated.

  When the power failure flag is set in step S406, the process proceeds to the recovery process shown in and after step S408. The fact that the power failure flag is set means that subroutine processing such as RAM clear processing in step S403 and setting change processing in step S405 is not executed at all. Therefore, the data in the RAM 153 is not rewritten at all, and the power recovery process requires confirmation processing such as whether or not the data in the RAM 153 is normal.

  For this purpose, first, in step S408, it is confirmed whether or not the RAM determination value is normal. Specifically, the value of the checksum in the RAM 153 is checked to check whether the value is normal, that is, whether the value of the checksum including the RAM determination value is 0. If the checksum value including the RAM determination value is 0, it is determined that the data in the RAM 153 is normal.

  If the RAM determination value is abnormal in step S408, that is, if the checksum value is not 0, there is a high possibility that the data in the RAM 153 has been destroyed. Therefore, in such a case, an error display process is performed in step S409. As error display processing, interrupt processing is first prohibited and all output ports in the input / output port 155 are cleared to control all actuators connected to the input / output port 155 to an off state. Thereafter, an error display for notifying the occurrence of an error to the hall manager or the like is performed, and this state is maintained until the reset switch 123 is turned on.

  If it is determined in step S408 that the RAM determination value is normal, the process proceeds to step S410, the stack pointer value stored in the backup area is written to the stack pointer of the CPU 151, and the stack state before the power is shut off is written. Return to the state. Next, in step S411, a power recovery command that tells execution of power recovery processing is transmitted to the display control device 111. Thereafter, in step S412, the game state is stopped and automatic settlement setting storage processing is performed. In step S413, various sensors such as the start detection sensor 71a are initialized. After the above processing is completed, the power failure flag is reset in step S414, and the processing returns to the address before the power is shut off. Specifically, the process returns to the timer interrupt process described above, and the watchdog timer clear process (step S204) is executed.

  Next, normal processing for performing main control related to the game will be described based on the flowchart of FIG.

  First, in step S501, it is determined whether or not a medal is max bet. If the medal is bet max, it is determined in step S502 whether the start lever 71 has been operated. If both step S501 and step S502 are YES, the lottery process in step S503, the reel control process in step S504, the medal payout process in step S505, and the special game state process in step S506 are executed in order, and the process returns to step S501. On the other hand, if the medal is not bet at step S501 or the start lever 71 is not operated at step S502, the process returns to step S501.

  Next, the lottery process in step S503 will be described based on the flowchart of FIG.

  In step S601, a random number table for determining success / failure is selected based on the current setting state of the slot machine 10 and the like. Here, the setting state of the slot machine 10 is any one of “setting 1” to “setting 6” set using a setting key (not shown), and the random number having the lowest winning probability of the combination when “setting 1” is set. A table is selected, and when “setting 6” is selected, the random number table having the highest winning probability of the combination is selected.

  In step S602, the lottery of the winning combination (winning lottery) is performed in light of the random number latched by the random number counter when the start lever 71 is operated on the random number table selected in this way. The random number counter generates random numbers in a predetermined area (for example, 0 to 65535 in decimal notation). When the medal is bet, the start lever 71 is latched at the timing when it is operated. For example, when the setting state of the slot machine 10 is “setting 3”, it corresponds to the big bonus (“red 7”, “blue 7”) when the random number value is “10 to 198”. 199-283 "corresponds to regular bonus (" BAR ")," 284-667 "corresponds to" watermelon ", and" 668-6364 "corresponds to" bell " , “6365 to 6876” corresponds to “cherry” with two payouts, “6877 to 7823” corresponds to “cherry” with four payouts, and “7824 to 16803” It corresponds to “Replay”.

  In step S603, it is determined whether or not any of the winning combinations (internal winning) is determined. If no winning combination is determined, the process is terminated. If any combination is won, the process proceeds to step S604, and a winning flag corresponding to the combination is set. In step S605, a reel table for reel stop control is determined and stored in the slip table storage area of the RAM 153, and then the present process is terminated. Here, when the symbols on the predetermined effective line at the timing when the stop switches 72 to 74 are pressed are different from the symbols to be stopped on the effective line, the slip table is a predetermined symbol to be stopped. It is a table that defines how much the reel slides so as to stop on the active line. For example, when the “replay” combination is won in which “replay” symbols are arranged on the active line, the replay sliding table is selected. For example, when the stop switch 72 is operated at the timing when the 18th “BAR” symbol of the left reel 42L (left belt) is positioned on the first effective line (center line), the 21st left belt It is determined that the “replay” symbol is stopped on the center line. Therefore, it is determined to perform the slip control of sliding the left reel 42L by 3 symbols.

  Next, the reel control processing in step S504 will be described based on the flowchart of FIG.

  In the reel control process, first, a wait process is performed in step S701. This wait process determines whether or not a predetermined time (for example, 4.1 seconds) has elapsed since the start of reel rotation in the previous game by checking an inter-game measurement timer. If it is, the reel rotation in the current game is permitted, and if it is denied, the reel is not allowed to rotate until a predetermined time has elapsed. Therefore, even if the player bets medals and operates the start lever 71, the reels 42L, 42M, and 42R may not immediately rotate.

  Following the wait process, the reel rotation process in step S702 is performed to rotate the reels 42L, 42M, and 42R. Note that the reel rotation process is executed such that rotation is started based on the timer interrupt process by allowing the timer interrupt. When the reel rotation process is executed, it is determined whether or not each of the reels 42L, 42M, and 42R is in a constant speed rotation state, and when the reels 42L, 42M, and 42R are in a constant speed rotation state, The rotational position of 42R is detected. At the same time as the reel rotation process is performed, an inter-game measurement timer and a forced stop timer are set.

  Thereafter, the process proceeds to step S703, and it is determined whether or not the rotational position (rotational angle position) of each reel 42L, 42M, 42R has been detected. If the rotational position is detected, the process proceeds to step S704, where one of the stop switches 72 to 74 is pressed to generate a reel stop command, more specifically from the stop detection sensors 72a to 74a. It is determined whether an ON signal is received. That is, in this embodiment, the period from when the reels 42L, 42M, 42R start to rotate until the rotation position of each reel 42L, 42M, 42R is detected is set as an invalid period. Even if the stop switches 72 to 74 are depressed, the ON signals from the stop detection sensors 72a to 74a are invalidated. If no stop command has been issued, the process proceeds to step S705, where a forced stop timer is checked to determine whether a predetermined maximum rotation time (for example, 40 seconds) of each reel 42L, 42M, 42R has elapsed. Determine. If the maximum rotation time has not elapsed, the process returns to step S704, and if the maximum rotation time has elapsed, the process proceeds to step S706 to perform a forced stop process for forcibly stopping the reels in a rotating manner.

  On the other hand, if any of the stop switches 72 to 74 is pressed in step S704 and a stop command is generated, the process proceeds to step S707 to perform reel stop processing. In this reel stop process, the reels corresponding to the pressed stop switches 72 to 74 are stopped. If a winning combination is won in the winning lottery and the winning flag is set, the reel table storage area of the RAM 153 is set. With reference to the stored slip table, control is performed so that the winning combinations are arranged on a predetermined effective line as much as possible. For example, when the “watermelon” role that “watermelon” symbols are arranged on the active line is won, and the left belt (left reel 42L) the tenth “watermelon” symbol stops on the center line, Middle reel 42M) When the stop switch 73 is pressed at the timing when the 9th “Blue 7” symbol is located on the center line, the middle reel 42M is checked for three symbols by checking against the slip table. It is decided to slide, and the 12th “watermelon” symbol of the middle belt stops on the center line. However, since the range that can be slid is determined in advance (for example, up to four symbols), the “watermelon” symbol may not stop on the active line depending on the timing of pressing the stop switch (for example, (When the stop switch 73 is pressed at the timing when the 14th “BAR” symbol of the middle belt is located on the center line). Even in the forced stop process in step S706, if the winning flag is set, the same process is performed.

  Subsequently, in step S708, it is determined whether or not the current stop command is the first stop command, that is, whether or not the stop switch has been pressed when all three reels are rotating. In the case of the first stop command, the process proceeds to step S709, and the slip table changing process is performed. In this slide table change process, for example, it is determined whether or not a combination of combinations occurs when trying to align a combination on the selected active line, and when a combination of combinations does not occur, the process proceeds to the next step as it is. When a combination of combinations occurs, the effective line having the same pattern is changed to another effective line, and at the same time, changed to a sliding table corresponding to the changed effective line. Here, “combination of a combination” means that, for example, when a “watermelon” symbol is arranged on the upper line, a “cherry” symbol appears on the lower line when the “cherry” symbol appears on the lower line. Refers to cases. The slip table changing process may be performed other than when avoiding the combination of the combinations.

  On the other hand, when the current stop command is not the first stop command in step S708, the process proceeds to step S710, and whether or not it is the second stop command, that is, one of the three reels is stopped and the two reels are rotating. It is determined whether or not the stop switch has been pressed. If it is the second stop command, the process proceeds to step S711 to perform stop eye determination processing. In this stop eye determination process, when two reels are stopped, it is determined whether or not the two symbols are aligned with a bonus symbol such as “Red 7” symbol. If the command is set to generate a sound effect or the like from the speaker 14, the process proceeds to the next step. In the stop eye determination process, it may be determined whether another condition other than two bonus symbols is satisfied, or a command for performing an effect using the auxiliary display unit 15 in addition to the sound effect. It may be set.

  Then, after the forced stop process in step S706, after the slip table change process in step S709, when the current stop command is not the second stop command in step S710, or the stop eye determination process in step S711 is performed. Thereafter, in step S712, it is determined whether or not all rotations of the left, middle, and right reels 42L, 42M, and 42R have stopped. If step S712 is NO, the process returns to step S704. If YES, the payout determination process is performed in the subsequent step S713, and then the process ends. In the payout determination process, it is determined whether or not the winning combination is lined up on the active line (whether or not a prize is won). When the winning combination is not aligned on the effective line, 0 is set in the payout planned number storage area of the RAM 153, When the combination is on the active line, it is determined whether or not the combination (winning combination) matches the internal winning combination. If the combination does not match, an error is displayed by the upper lamp 13 and the number of payouts Set 0 in the storage area. If they match, the number of payouts corresponding to the combinations arranged in the payout amount storage area is set.

  Next, the medal payout process in step S505 will be described based on the flowchart of FIG.

  In the medal payout process, first, it is determined whether or not the payout number counted by the payout number counter in step S801 matches the planned payout number stored in the payout planned number storage area. If the number of payouts does not match the planned payout number, it is determined in step S802 whether or not the game is being performed in the credit mode. If it is in the credit mode, it is determined in step S803 whether or not the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit is not reached, the count value of the credit counter and the number of payouts are each incremented by 1 in step S804. Accordingly, the remaining number display unit 35 and the acquired number display unit 37 are each incremented by one.

  On the other hand, when the game is performed in the direct mode, or when the count value of the credit counter reaches the upper limit, the medal payout rotary plate is driven in step S805 and the medal is discharged from the hopper device 91 to the medal discharge port. 17 through the medal tray 18. At this time, in step S806, the number of payouts is incremented by 1 according to the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. As a result, the number of acquired number display section 37 is incremented by one. Then, after the payout number is incremented by 1 in step S804 or step S806, the process returns to step S801 again. When the number of payouts and the planned number of payouts match in step S801, the medal payout rotating plate of the hopper device 91 is stopped in step S807, and this process is terminated. The payout number / acquired number display section 37 is reset when the start lever 71 is operated next time.

  Next, the special game state process of step S506 will be described based on the flowchart of FIG.

  Prior to the description of the special game state process, the bonus game will be described. The regular bonus (hereinafter referred to as “RB”) game is composed of 12 JAC games. The JAC game is a game in which only one bet is allowed, and the JAC symbol (in this embodiment, the replay-replay-replay or blue 7-replay-replay sequence corresponds to the JAC symbol) stops on the active line. It is a game with a very high probability, that is, establishment of establishment of a JAC symbol. When a JAC symbol is established in a JAC game, the maximum number (15 in this case) of medals is paid out. When the JAC symbol is established 8 times, the RB game is ended even before the JAC game reaches 12 times. On the other hand, the big bonus (hereinafter referred to as “BB”) game is composed of 30 small role games and 3 JAC ins. A small role game is a game in which a small role is won with a high probability (“Bell” symbols etc. are on the active line), and JAC in means entering the JAC game 12 times. When JAC in symbols (replay symbols in this case substitute) are aligned on the active line, JAC in is established. The JAC game is the same as that of the RB game. Also, when the JAC game by the third JAC in is finished, the BB game is finished even before the small role game reaches 30 times, and before the JAC in reaches 3 times after the 30 small role games are finished. Even if there is, the BB game ends.

In the special game state process, first, in step S901, it is determined whether or not the game state is a bonus game. If it is not during the bonus game, the process proceeds to step S902, and bonus symbol determination processing is performed.

  In this bonus symbol determination process, as shown in FIG. 19, it is first determined in step S1001 whether or not the RB winning flag is set. If it is set, the process proceeds to step S1002, and the RB symbol is placed on the current effective line. It is determined whether or not (for example, “BAR” symbols) are aligned, and if the RB symbols are not aligned, this processing is terminated. On the other hand, when the RB symbols are aligned on the active line this time, in step S1003, the RB winning flag is reset and the RB setting flag is set to make an RB game which is one type of bonus game, and the RB game initial setting process shown in FIG. To finish this processing.

  If the RB winning flag is not set in step S1001, it is determined whether or not the BB winning flag is set in step S1004. If it is not set, the process is terminated. When the BB winning flag is set, the process proceeds to step S1005, where it is determined whether or not the BB symbol (for example, the symbol “red 7”) is aligned on the current effective line, and when the BB symbol is not aligned, the process is terminated. To do. On the other hand, when the BB symbols are aligned on the active line this time, in step S1006, the BB winning flag is reset and the BB setting flag is set to set the BB game as one type of bonus game, and the BB game initial setting process shown in FIG. To finish this processing.

  20 and 21, the remaining small role game counter represents the remaining number of small role games (also referred to as the remaining small role game number), and the remaining JAC in counter is the remaining number of remaining JAC in (remaining JAC in number). The remaining JAC establishment counter represents the remaining number of times that the JAC symbol can be established (also referred to as the number of remaining JAC formations), and the remaining JAC game counter represents the number of remaining JAC games (also referred to as the number of remaining JAC games). To express. The number of remaining small role games, the number of remaining JAC ins, the number of remaining JACs established, and the number of remaining JAC games are displayed on the game number display unit 36 as appropriate. By the way, when the small role winning flag is set by winning a small role in the role lottery, if the small role symbol is not aligned on the active line in the game, these winning flags will be reset, When RB or BB is won and the RB winning flag or the BB winning flag is set, even if the RB symbol or BB symbol is not aligned on the active line in the game, these winning flags are carried over next time. In the lottery process in the next game that carries the BB or RB winning flag, a lottery regarding whether or not a small role is won is performed, but a lottery regarding BB or RB is not performed. In addition, when a small combination is won in a state where the BB or RB winning flag is carried over, a sliding table is stored so that the small combination is preferentially aligned.

  Now, referring back to FIG. 18, when the gaming state is a bonus game in step S901, it is determined in step S903 whether the bonus game is a JAC game. If it is not a JAC game, it means that the BB game is in the small role game, so the process proceeds to step S904, and it is determined whether or not the JAC in symbols are aligned on the active line. When the JAC in symbols are aligned on the active line, the JAC game is started in step S905 and the JAC game initial setting process during the BB game shown in FIG. 21B is performed, and this process ends. On the other hand, if the JAC in symbols are not aligned on the active line in step S904, the small role game has been consumed, so in step S906, the number of remaining small role games is decremented by 1, and the process proceeds to step S907. It is then determined whether or not the number of remaining small role games has become zero. When the remaining small role game number is not 0, the present process is terminated. When the remaining small role game number is 0, the process proceeds to step S908, and a special game state end process for appropriately resetting various setting flags, BB setting flags, various counters, etc. To end this process.

  When the gaming state is a JAC game in step S903, the process proceeds to step S909 to determine whether or not the JAC symbols are aligned on the active line. When the JAC symbols are aligned on the active line, the number of remaining JACs established is determined in step S910. Decrement by one. After that, or when the JAC symbols are not aligned on the active line in step S909, one JAC game has been consumed, so the number of remaining JAC games is decremented by 1 in step S911. Subsequently, in step S912, it is determined whether or not any of the remaining number of JACs or the number of remaining JAC games has become 0. If neither is 0, that is, the JAC symbol has not yet been established 8 times. If the JAC game has not been digested 12 times, the process is terminated as it is. On the other hand, if any of them is 0, that is, if the JAC symbol is established 8 times or the JAC game is digested 12 times, the JAC in is digested once, so in step S913 the remaining JAC in The number of times is decremented by 1, and in the subsequent step S914, it is determined whether or not the number of remaining JAC in is zero. When it is 0, the special gaming state termination process of step S908 described above is performed, and this process is terminated. Incidentally, if the bonus game is an RB bonus, the initial remaining JAC in number is 1 (see FIG. 20), so it becomes 0 in step S913, and a positive determination is always made in step S914, and the special game in step S908. The RB setting flag is reset in the state end process.

  On the other hand, when the number of remaining JAC ins is not zero in step S914, that is, when the JAC in has not been digested three times in the BB game, after performing the JAC game end processing for resetting the JAC game setting flag in step S915, When the player enters the game, one of the small role games is digested, so the number of remaining small role games is decremented by 1 in step S906, and then whether or not the remaining small role game number has become 0 in step S907. If it is determined that the number of remaining small role games is 0, the special game state ending process in step S908 described above is performed, and this process is ended. On the other hand, when the remaining small-combination game number is not 0, the small-combination game in the BB bonus has not reached 30 times and the JAC in has not reached 3 times.

  Now, in the present embodiment, the medal information storage area 191 as the insertion number storage means and the given number storage means provided in the RAM 183 of the display control device 111 is configured to store information relating to increase / decrease of medals ( (See FIG. 8). The medal information storage area 191 includes first and second bet storage areas (first and second normal time insertion number storage means), and first and second payout storage areas (first and second normal time grant number storage means). The BB game bet storage area (special time insertion number storage means) and the BB game payout storage area (special time grant number storage means) are configured to individually store corresponding medal information.

  In addition, the display control device 111 includes first and second game number counters (first and second normal game number measuring means) so that the number of games is counted. In addition, as described above, in the present embodiment, the backup power is supplied from the power supply device 161 to the display control device 111. Therefore, even when the power is turned off, the stored contents of the medal information storage area 191 are stored. Retained.

  Hereafter, the process (medal information storage process) which medal information is memorize | stored in the display control apparatus 111 is demonstrated, referring FIG. The medal information storage process is executed in a normal process that is periodically performed in the display control device 111. Normal processing performed in the display control device 111 is synchronized with timer interrupt processing periodically executed in the main control device 131, and in this example, has a cycle of 1.49 msec. Further, the display control device 111 temporarily stores the medal information transmitted from the main control device 131 in a register provided in the CPU 181.

  First, in step S2001, a BB game bet storage process is performed. Here, it is confirmed whether or not information related to medals bet during the BB game as medal information (BB game bet medal information) is transmitted from the main control device 131. When the bet medal information during the BB game is confirmed, the number of medals newly added this time is added to the cumulative medal number already stored in the bet storage area during the BB game, and the number of medals after the addition is added to the BB game. Overwrite the medium bet storage area. Here, the number of medals stored in the bet storage area during the BB game is targeted for medals betted to start a game, and medals credited by excessively inserting medals into the medal insertion slot 75 are included. I can't. Even when the bet medal information during the BB game is not confirmed, the process proceeds to the next step S2002. Similarly, in the following steps, even if the corresponding medal information is not confirmed, the process proceeds to the next step.

  In step S2002, a BB game payout storage process is performed. Here, it is confirmed whether or not information related to medals paid out during the BB game as medal information (payout medal information during BB game) is transmitted from the main control device 131. When the payout medal information during the BB game is confirmed, the medal number newly added this time is added to the accumulated medal number already stored in the payout storage area during the BB game, and the added medal number is added to the BB game. Overwrite the medium payout storage area. Here, the number of medals stored in the payout storage area during the BB game is for medals paid out based on the fact that the winning combination is established on the active line, and includes medals that are credited.

  In step S2003, a base game bet storage process is performed. Here, it is confirmed whether or not information related to medals bet during the normal game (ordinary game bet medal information) is transmitted from the main control device 131 as medal information. When the normal game bet medal information is confirmed, the number of medals newly added this time is added to the cumulative number of medals already stored in the first and second bet storage areas, and the number of medals after the addition Are overwritten in the first and second bet storage areas, respectively. Here, the number of medals stored in the first and second bet storage areas is for medals betted to start a game, and medals that are credited when excessive medals are inserted into the medal insertion slot 75. Is not included.

  In step S2004, a payout storage process during a normal game is performed. Here, it is confirmed whether or not information related to medals paid out during the normal game (medical game payout medal information) is transmitted from the main control device 131 as medal information. When the payout medal information during the normal game is confirmed, the number of medals newly added this time is added to the cumulative number of medals already stored in the first and second payout storage areas, and the number of medals after the addition Are overwritten in the first and second payout storage areas, respectively. Here, the number of medals stored in the first and second payout storage areas is for medals paid out based on the fact that a winning combination is established on the active line, and includes medals to be credited.

  In step S2004, the first and second game number counters are incremented by 1 based on the fact that one normal game is played. After performing the above series of processes, the present process is terminated.

  The display control device 111 is also configured to receive a power failure signal from the power failure monitoring circuit 161b when the power is shut down due to the occurrence of a power failure or the like, and is displayed as a power failure flag generation process associated with the occurrence of a power failure or the like. The display power failure flag is set in the NMI interrupt processing. Then, when it is determined whether or not the display power failure flag is set in the normal processing of the display control device 111, if the display power failure flag is set, the power failure processing (display power failure processing) is performed. . In the display power failure process, it is determined whether or not the medal information is stored in the medal information storage area 191 by checking whether or not there is medal information in the register of the display control device 111. If the medal information has not been stored in the medal information storage area 191, the process is terminated and the process returns to the normal process (medal information storage process), and the medal information is stored in the medal information storage area 191. Complete. In this way, it is determined whether or not the medal information has been stored in the medal information storage area 191 at the initial stage of the display power failure process. If the medal information is not yet completed, the medal information storage process is given priority. There is no need to construct a display power failure processing program that also takes into account that the display power failure processing is executed during the information storage process. As a result, the display power failure processing program can be simplified and the ROM 182 can be reduced in capacity.

  On the other hand, when the medal information is stored in the medal information storage area 191, the infinite loop is entered in preparation for the case where the power supply is completely shut down and the processing cannot be executed. If a power recovery command is transmitted, the display power failure flag processing is terminated, the display power failure flag is reset, and then the processing normally performed by the display control device 111 is restored. By adopting the above configuration, medal information can be reliably stored in the medal information storage area 191. The power supply unit 161a of the power supply device 161 holds the output of the stabilization voltage used as the drive voltage for the control system for a sufficient time to execute the above-described medal information storage process and display power failure process. It is configured.

  In the present embodiment, the display control device 111 is configured to perform a process (base monitoring process) for monitoring the increase / decrease of medals between a predetermined number of games. As the base monitoring process, every time a predetermined number of games are played, the “total number of medals paid during that time” is calculated with respect to the “total number of medals betted during that time”. The number of medals (hereinafter referred to as “medal grant rate”) is calculated. Further, it is determined whether or not the medal grant rate is within a specified range. In addition, the display control device 111 is connected to an external concentration terminal board 171 that can transmit information to the hall management device (hall computer) (see FIG. 8), and it is determined that the medal grant rate is not within the specified range. A notification process for notifying that effect is executed.

  In the calculation of the specified range, for example, a large number of sample data of medal grant rates when a specified number of games have been played are obtained by experiment, and the distribution of the experimental data of the medal grant rate is obtained and then statistical I do. Then, after calculating the average value X of the medal grant rate, a distribution curve Y as shown in FIG. 25 is obtained from the statistical data. The distribution of the medal grant rate (medal grant rate distribution curve Y) may be calculated by calculation based on each small role winning probability or the like. In the present embodiment, the standard deviation (SD) is obtained based on the distribution curve Y, and the value obtained by multiplying the average value X by the standard deviation SD is added or subtracted, and the numerical values (X + 3SD, X-3SD) are respectively obtained. The specified range is set as the upper and lower threshold values d1 and d2. That is, the notification process is executed when the medal grant rate distributed over approximately 99.73% falls outside the range. In this case, the probability of exceeding the upper limit (upper limit threshold d1) of the specified range and the probability of falling below the lower limit (lower limit threshold d2) of the specified range are about 0.135%, respectively. Of course, the value is not limited to the above numerical value. For example, different setting methods may be used for the upper limit threshold d1 and the lower limit threshold d2.

  In the present embodiment, a short-term (for example, between 100 games) medal increase / decrease and a long-term (for example, 1000 games) medal increase / decrease are monitored. Hereinafter, monitoring of increase / decrease in medals between a small number of games is also referred to as “first monitoring”, and monitoring of increase / decrease in medals between large numbers of games is also referred to as “second monitoring”.

  The display control device 111 includes a specified range storage area (threshold storage means) in which a specified range is stored, and is referred to when determining whether or not the medal grant rate is within the specified range. Yes. In this specified range storage area, there are a first monitoring (first specified range storage area) and a second monitoring (second specified range storage area). In addition, if the setting state of the slot machine 10 changes, the variation of the medal grant rate naturally also changes. Therefore, the first and second prescribed range storage areas store prescribed ranges corresponding to the respective setting states of the slot machine 10. Yes. That is, the specified range to be applied is selected based on the setting state of the slot machine 10 and whether or not it is the first monitoring. Since the medal grant rate variation increases as the number of games decreases, the specified range (first specified range) applied during the first monitoring is the specified range (second specified range) applied during the second monitoring. ) Is wider (the upper threshold is set higher and the lower threshold is set lower).

  In addition, when the display control device 111 determines that the medal grant rate is within the specified range and determines that the medal grant rate is not within the specified range (out of the specified range), the display control device 111 is out of the range to store that fact. An out-of-range storage area is provided as storage means. Regarding this out-of-range storage area, there are a first monitoring (first out-of-range storage area) and a second monitoring (second out-of-range storage area). The contents stored in the out-of-range storage area are cleared when it is determined in the next base monitoring process that the medal grant rate is within the specified range.

  The base monitoring process will now be described with reference to the drawings. The base monitoring process is also executed in a normal process that is periodically performed in the display control device 111. This base monitoring process includes a process for monitoring increase / decrease in medals during a normal game and a process for monitoring increase / decrease in medals during a BB game. First, a process for monitoring increase / decrease in medals during a normal game (normal base monitoring) Processing) will be described with reference to FIG. It should be noted that the RB game and the JAC game are considered to be less likely to be fraudulent with respect to the granting of medals based on the contents of the game. Therefore, in this embodiment, the increase / decrease of medals is performed for the RB bonus and the JAC game. Do not monitor.

  First, in step S2101, the first game number counter is checked to determine whether the number of games has reached 100 games. If it is determined that the number of games has reached 100, the first calculation process is performed in step S2102.

  In the first calculation process of step S2102, the first bet storage area and the first payout storage area are confirmed, and “the total payout medal number stored in the first payout storage area / stored in the first bet storage area”. “Total bet medals” is calculated to calculate the first medal grant rate.

  Thereafter, in step S2103, the first specified range stored in the first specified range storage area is confirmed, and whether or not the calculated value (first medal grant rate) by the first calculation process is within the first specified range. Determine (first monitoring). If the determination is affirmative, a first out-of-range information clear process is performed in step S2104. Here, the first out-of-range storage area is confirmed, and when information indicating that the first medal grant rate is out of the first specified range is stored in the first out-of-range storage area, the information is cleared. . On the other hand, if negative in step S2103, the first and second out-of-range storage areas are confirmed in step S2105, and information indicating that the medal grant rate is out of the specified range is stored in at least one out-of-range storage area. It is determined whether or not. If the result is negative, information indicating that the first medal grant rate is outside the first specified range is stored in the first out-of-range storage area in step S2106.

  On the other hand, if the result in step S2105 is affirmative, after setting the out-of-range flag in step S2107, the present process is terminated.

  In addition, when it is confirmed that the out-of-range flag is set in a normal process periodically performed in the display control device 111, a notification process is performed. In this notification process, a display mode different from the normal time is derived on the upper lamp 13, the auxiliary display unit 15, etc., or an unusual situation regarding the increase or decrease of medals has occurred to the hole management device (hole computer). Or send a signal. The display mode for notification is continuously derived for a predetermined time, and after the predetermined time has elapsed, the out-of-range flag is reset and normal effect display is performed again. This notification display is given priority over other effect displays. For example, even when the change of the reel 45 is started, the notification display is being performed. The effect display associated with the start of fluctuation of the reel 45 is not performed. Note that as the notification process, an error sound may be derived in the speaker 14. Also, a notification reset button for resetting the out-of-range flag may be provided so that notification by the notification process is continuously performed until the notification reset button is operated (until the out-of-range flag is reset). Good.

  When the first out-of-range information clear process is performed in step S2104, or when information indicating that the first medal grant rate is out of the first specified range is stored in the first out-of-range storage area in step S2106, After the first information clear process is performed in step S2108, this process ends. In the first information clear process, the storage contents of the first bet storage area and the first payout storage area are cleared and the first game number counter is reset. In this way, by performing the first information clearing process, every time 100 games are played, the total number of medals bet and the total number of medals paid out during the 100 games are surely grasped, and the total number of bet medals concerned. And the medal grant rate (first medal grant rate) based on the cumulative number of payout medals can be reliably calculated.

  If NO in step S2101, the second game number counter is checked in step S2109 to determine whether the number of games has reached 1000 games. If it is determined that the number of games has reached 1000 games, the process proceeds to step S2110 and the second calculation process is performed. If it is determined that the number of games has not reached 1000 games, the process is terminated. To do.

  In the second calculation process in step S2110, the second bet storage area and the second payout storage area are confirmed, and “the total payout medal number stored in the second payout storage area / stored in the second bet storage area”. The “total bet medals” is calculated to calculate the second medal grant rate.

  Thereafter, in step S2111, the second specified range storage area is confirmed, and it is determined whether or not the calculated value (second medal grant rate) by the second calculation process is within the second specified range (second monitoring). ). If the determination is affirmative, a second out-of-range information clear process is performed in step S2112. Here, the second out-of-range storage area is confirmed, and when information indicating that the second medal grant rate is out of the second specified range is stored in the second out-of-range storage area, the information is cleared. To do.

  On the other hand, if the result in Step S2111 is negative, the first and second out-of-range storage areas are confirmed in Step S2113, and information indicating that the medal grant rate is out of the specified range is stored in at least one out-of-range storage area. It is determined whether or not. If the result is negative, information indicating that the second medal grant rate is outside the second specified range is stored in the second out-of-range storage area in step S2114. On the other hand, if the determination in step S2113 is affirmative, the out-of-range flag is set in step S2115, and then this process ends.

  When the second out-of-range information clear process is performed in step S2112 or when information indicating that the second medal grant rate is out of the second specified range is stored in the second out-of-range storage area in step S2114, step After the second information clear process is performed in S2116, this process ends. In the second information clear process, the stored contents of the second bet storage area and the second payout storage area are cleared and the second game number counter is reset. In this way, by performing the second information clear process, every time 1000 games are played, the total number of medals bet and the total number of medals paid out during the 1000 games are surely grasped, and the total number of bets medals And the medal grant rate (second medal grant rate) based on the cumulative payout medal number can be reliably calculated.

  Next, a process for monitoring the medal increase / decrease during the BB game (BB base monitoring process) will be described with reference to FIG. As this BB base monitoring process, by calculating the “total medals paid out during the small role game in the BB game” with respect to the “number of medals bet during the small role game in the BB game”, per game The number of acquired medals (hereinafter referred to as BB medal grant rate) is calculated. Further, it is determined whether or not the BB medal grant rate is within the BB prescribed range. This BB specified range may be individually set according to the number of target small role games, and a corresponding specified range may be selected according to the number of small role games played during the BB game. . When the BB medal grant rate is not within the BB prescribed range (when it is outside the prescribed range), the notification process is executed. The BB specified range is stored in a BB specified range storage area (special time threshold storage means) provided in the display control device 111. If it is determined that the BB medal grant rate is outside the BB prescribed range, that fact is stored in the BB out-of-range storage area as the out-of-range storage means provided in the display control device 111. It has become.

  First, in step S2201, it is determined whether or not the BB game has ended. If it is determined that the BB game has ended, the BB in-process operation is performed in step S2202, and if it is determined that the BB game has not ended, the present process ends.

  In the calculation process during BB in step S2202, the bet storage area during BB game and the payout storage area during BB game are confirmed, and “the total number of payout medals stored in the payout storage area during BB game / the bet storage area during BB game”. The “total bet medals stored” is calculated to calculate the BB medal grant rate.

  Thereafter, in step S2203, the BB prescribed range storage area is confirmed, and it is determined whether or not the calculated value (BB medal grant rate) obtained during the BB calculation processing is within the BB prescribed range. If the determination is affirmative, in step S2204, BB out-of-range information clear processing is performed. Here, the storage area outside the BB range is confirmed, and when information indicating that the BB medal grant rate is outside the BB specified range is stored in the storage area outside the BB range, the information is cleared.

  On the other hand, if the result in Step S2203 is negative, the storage area outside the BB range is confirmed in Step S2205, and whether or not information indicating that the BB medal grant rate is outside the BB specified range is stored in the storage area outside the BB range. Is determined. If the result is NO, in step S2206, information indicating that the BB medal grant rate is outside the BB specified range is stored in the BB out-of-range storage area in the BB out-of-range storage area. On the other hand, if the result in step S2205 is affirmative, after setting the out-of-range flag in step S2207, the present process is terminated. That is, when information indicating that the BB medal grant rate is outside the BB prescribed range is stored in the storage area outside the BB range, when it is further determined that the BB medal grant rate is outside the BB prescribed range (BB medal) The notification process is executed when the grant rate is determined to be out of the BB specified range twice consecutively.

  When the BB out-of-range information clear process is performed in step S2204, or when information indicating that the BB medal grant rate is out of the BB prescribed range is stored in the BB out-of-range storage area in the BB out-of-range storage area in step S2206. After performing the BB information clear process in step S2208, the present process is terminated. In the BB information clear process, the stored contents of the bet storage area during the BB game and the payout storage area during the BB game are cleared. In this way, by performing the B information clear process, each time a BB game is played, the total number of medals bet and the total number of medals paid out during the one BB game are surely grasped. The medal grant rate (BB medal grant rate) based on the cumulative bet medal count and the cumulative payout medal count can be reliably calculated.

  As described above in detail, in this embodiment, the ratio of the cumulative medal number stored in the grant storage area to the cumulative medal number stored in the bet storage area is calculated, whereby the medal grant per game is calculated. Rate is obtained. Then, the comparison result between the calculated medal grant rate and the standard prescribed range is used as an index as to whether or not the medal grant has been fraudulent, and the medal grant rate is not within the prescribed range, that is, the prescribed range. If it deviates from the above, it can be notified to that effect, and as a result, fraudulent acts related to the granting of medals can be suppressed.

  In particular, when the medal grant rate exceeds the upper limit of the specified range, the notification process is performed, so that an act of illegally acquiring the game medium by the player can be suppressed. As a result, it is possible to deter disadvantages that extend to the hall side due to cheating. In addition, if the hall side tries to obtain a certain profit as a whole hall, it may be possible to collect the loss of the medals that were illegally drawn from those who play games on other gaming machines (bona fide players) It is done. Then, for those who are playing games with the other gaming machines, there is a risk of incurring an unexpected loss. In this regard, in the present embodiment, since it is possible to suppress an illegal act such as illegally pulling out a medal, it is possible to effectively suppress the above-described problem.

  Further, even when the medal grant rate falls below the lower limit value of the specified range, it is possible to suppress a situation in which it is difficult to acquire game media due to cheating on the hall side by performing the notification process. That is, it is possible to suppress an illegal act in which the hall side replaces the regular main control device 131 (ROM 152) with an unauthorized main control device 131 in which the winning probability of the winning combination is unreasonably low in the winning lottery.

  Further, if the configuration is such that the determination as to whether or not an illegal act has been performed on the hall side, there is a concern that the concealment may be performed freely on the hall side. In this regard, in the present embodiment, since it is configured to determine whether or not an illegal act is performed in the slot machine 10, it is possible to directly notify the slot machine 10 without going through the hall side. Therefore, the above concerns can be eliminated.

  In addition, in the bonus game (BB game, RB game), a large number of medals are awarded in a short period of time, so the medal grant rate during the bonus game is larger than the medal grant rate during the normal game without the bonus game. It has come to exceed. In other words, if the medal grant rate is obtained by collectively collecting the medal number accumulated in the normal game and the medal number accumulated in the bonus game, the standard range (upper and lower thresholds) as a reference There is a concern that this must be roughly set.

  In this regard, in this embodiment, the number of game media betted and awarded in the base game and the number of game media betted and awarded in the BB game are individually accumulated and stored, and the medal grant rate in the base game and the number of game media in the BB game are individually stored. The medal grant rate is calculated individually. For this reason, the threshold value can be set to a more precise specified range that individually corresponds to the base game and the BB game. As a result, it is possible to more accurately determine whether or not the medal grant rate is within the specified range in each gaming state, and it is possible to more reliably prevent fraud related to the medal granting in each gaming state. In addition, the risk of erroneous detection can be reduced.

  In the present embodiment, the medal grant rates between different numbers of games (100 games and 1000 games) are calculated and compared with the corresponding specified ranges in the normal game. For this reason, the medal grant rate can be monitored in a double manner, and the above-described effect is more reliably achieved. Further, by performing short-term (100 games) monitoring and long-term (1000 games) monitoring, for example, it is possible to detect fraud such as concentrating medals illegally in the short term. At the same time, it is possible to detect fraud such as gradually acquiring medals over the long term, and the above-described effects are further achieved.

  In addition, in the present embodiment, notification is not performed when the medal grant rate deviates once from the specified range, but during the normal game, at least one of the first and second out-of-range storage areas has a medal grant rate. The notification process is executed when it is determined that the medal grant rate is outside the specified range in a state where information indicating that the value is outside the specified range is stored. Further, even during the BB game, it is determined that the BB medal grant rate is further out of the BB specified range in a state where information indicating that the BB medal grant rate is out of the BB specified range is stored in the storage area outside the BB range. The notification process is executed in the case of a failure. Therefore, the reliability and accuracy of notification can be improved. For example, there may be a case where the medal grant rate accidentally deviates from the specified range by chance even though no illegal act has been performed. In such a case, the notification process is executed and the game Such as giving an unpleasant impression to a person.

  In the present embodiment, since the display control device 111 detects fraud, the burden on the main control device 131 can be reduced. Therefore, the processing content in the main control device 131 can be simplified, whether the main control device 131 is genuine (whether the main control device 131 has been replaced with an illegal main control device), the main control Inspections such as whether the processing of the device 131 is normally performed can be performed relatively easily. In recent display control devices 111, programs for controlling the auxiliary display device 15 and the like are complicated. In this embodiment, the display control device 111 performs a series of processes such as cumulative medal storage, medal grant rate calculation, and determination as to whether the medal grant rate is within a specified range. For this reason, it becomes difficult to perform the above-described series of processing by analyzing or altering the program or the like of the display control device 111. Therefore, by not performing the above-described series of processing, it is illegal to determine whether or not the medal grant rate is within a specified range, or to notify that effect. Can be suppressed.

  The medal grant rate calculated during the normal game is based on the cumulative number of medals betted during that time and the cumulative number of medals awarded during that time every 100 games in the first monitoring and every 1000 games in the second monitoring. Is calculated. Therefore, since the number of games to be determined is unified for each of the first monitoring and the second monitoring, the same specified range can be adopted for each of the first monitoring and the second monitoring. Can be simplified.

  When the medal grant rate is calculated, the stored contents of the corresponding bet storage area and grant storage area are erased, so that it is possible to prevent excess data from being accumulated, and the medal information storage area 191 is small. Capacity can be increased.

  In addition, it is not limited to the description content of embodiment mentioned above, For example, you may implement as follows.

  (A) In the above embodiment, as history storage means for individually storing the number of medals bet and the number of medals awarded in each game between a predetermined number of games (for example, the last 100 games). A history storage area may be provided. In that case, by reading the stored contents of the history storage area, the bet and grant history of medals between a predetermined number of games can be grasped, and the reason why the notification process is executed can be clarified. Therefore, by reading the stored contents of the history storage area at the time of notification, it is possible to explain the situation in more detail to the fraudulent person or to confirm that it is a false notification.

  A history display device that displays the stored contents of the history storage area may be provided. In that case, the stored contents of the history storage area can be quickly grasped. In that case, the storage contents of the history storage area can be quickly grasped at the time of notification, or the storage contents of the history storage area can be always grasped. Furthermore, when the predetermined number of games increases, a history of betting numbers and the number of game media to be awarded and a medal grant rate between the predetermined number of games may be displayed in a graph. Further, the contents stored in the history storage area may be configured to be displayed on the auxiliary display unit 15.

  (B) In the above-described embodiment, the process of transmitting the number information of bet medals as the medal information of the main control device 131 and the process of accumulating the bet number of bets of the display control device 111 may be omitted. In the above embodiment, since three medals are required to start the game (except during the RB game and the JAC game), the cumulative bet medals bet between predetermined games can be calculated from the number of games. it can. As an example of this case, when the number of games reaches a predetermined number of times (for example, 100 times for the first monitoring, 1000 times for the second monitoring), a predetermined number of games are played from the number of games. There is a configuration in which the number of medals bet in between is calculated (the number of game media betted per game × predetermined number of times). In this case, the display control device 111 corresponds to the input number calculating means. In addition, since the number of medals bet during a predetermined number of games can be calculated in advance, the bet storage area stores in advance the number of medals bet during a predetermined number of games. Is mentioned. In this case, the bet storage area corresponds to the prescribed insertion number storage means. When such a configuration is adopted, it is possible to simplify the control content and configuration.

  Furthermore, since the medal grant rate is calculated every time a predetermined number of games are played, the number of medals bet between the predetermined games is constant, so that the control content or configuration can be further simplified. it can.

  Further, the number of medals bet during a predetermined number of games that are calculated in advance or calculated from the number of games as in the above example, and the predetermined number of games are performed as in the above embodiment. It is determined whether or not a medal bet has been made normally by determining whether or not the accumulated value of the medal number information transmitted from the main control device 131 matches. Can do.

  (C) In the said embodiment, you may comprise so that the alerting | reporting content by alerting | reporting process may differ between the case where a medal grant rate exceeds the upper limit of a regulation range, and the case where it falls below a minimum. In this case, it is possible to grasp whether the notification has been performed because the medal grant rate is too high, or whether the notification has been performed because the medal grant rate is too low. The player can take appropriate countermeasures. For example, when the medal grant rate exceeds the upper limit of the prescribed range, only notification to the hall side is performed, and when the medal grant rate falls below the lower limit of the prescribed range, only notification at the slot machine 10 or its peripheral part is performed. It may be configured. In particular, if the medal grant rate falls below the lower limit of the prescribed range so that even a player who is playing for the first time can be notified, the hole side that has performed the fraudulent act is less likely to escape, so the above effect is achieved. Played one more time.

  (D) Also, in the out-of-range storage area, information that the medal grant rate is outside the specified range is not stored, but the medal grant rate exceeds the upper limit of the specified range or falls below the lower limit. You may comprise so that it may be memorize | stored. In this case, for example, in a state where information indicating that the medal grant rate exceeds the upper limit of the prescribed range is stored in the out-of-range storage area, the notification process is executed when the medal grant rate falls below the lower limit of the prescribed range. Therefore, the risk of false notification (false detection) can be further reduced.

  (E) In the above embodiment, during the normal game, in a state where information indicating that the medal grant rate is outside the specified range is stored in at least one of the first and second out-of-range storage areas, the medal grant rate Is determined to be outside the specified range, the notification control is executed. However, the present invention is not particularly limited to such a configuration. Notification control can be executed when it is determined a predetermined number of times that the medal grant rate set appropriately for each model is out of the specified range during a predetermined period set appropriately for each model (even during the BB game) The same). For example, the notification control may be executed when it is determined once that the medal grant rate is out of the specified range. Here, examples of the predetermined period include a period until a predetermined number of games are played, a period until a predetermined time elapses, a period until a medal grant rate is calculated a predetermined number of times, and the like.

  (F) In the above embodiment, as a stage before notification is made at the gaming machine or in the vicinity thereof (for example, in a state where information indicating that the medal grant rate is out of the specified range is not stored in the out-of-range storage area) When it is determined that the grant rate is out of the specified range), the hall computer may be notified first that the medal grant rate is out of the specified range. In that case, before being informed in the slot machine 10, that is, before the fraudster is aware that the fraudster has been detected, the hall personnel can monitor the behavior of the fraudster. When notified, the reason / foundation can be explained more clearly to the fraudster. However, if the medal grant rate falls below the lower limit of the prescribed range, such a previous notification is not necessary.

  (G) In the above embodiment, the upper and lower threshold values are obtained by adding or subtracting the triple value of the standard deviation to the average value of the medal grant rate calculated from the small role establishment probability or the like in the specified range. Can be set appropriately for each model. Further, in the above embodiment, the width from the average value to the upper limit of the specified range and the width from the average value to the lower limit are set to be the same. The width on the lower limit side may be shorter than the width of.

  (H) In the above embodiment, the medal grant rate calculated during the normal game is calculated for every 100 games in the first monitoring and for every 1000 games in the second monitoring. It can be set appropriately. For example, the medal grant rate is calculated for each game based on the number of bets and the number of awarded medals in the most recent predetermined game (for example, the most recent 100 games in the first monitoring and the most recent 1000 games in the second monitoring). It may be configured.

  (I) In the above embodiment, the medal grant rate is calculated every predetermined number of times. However, the medal grant rate may be irregular (non-regular). For example, in the above embodiment, each time the medal grant rate is calculated, the corresponding bet storage area and the storage contents of the grant storage area are erased. The number of medals bet and the number of medals awarded may be accumulated and stored in the bet storage area and the grant storage area to calculate the total medal grant rate so far. In that case, it is possible to calculate the medal grant rate in accordance with the progress of the game, and to detect illegal or illegal changes that can be detected by observing the increase or decrease in medals over a very long period of time (an act of gradually pulling out medals) Can also be detected. Further, the total medal grant rate of each slot machine can be sampled as data, which can be used as data for determining the setting state of each slot machine and for product development.

  However, in the case of adopting the above configuration, the threshold value corresponding to the target game number varies depending on the number of games to be processed. Therefore, it is desirable to set a prescribed range according to the number of games. When such a configuration is adopted, an erasing unit for erasing the stored contents of the bet storage area and the grant storage area may be provided. The erasing means may be configured to serve as the reset switch 123, the setting key insertion hole 124, and the power switch 122.

  (J) In the above embodiment, every time the specified number of games (100 games or 1000 games) is played, the number of medals and the number of payouts bet between the specified number of games (between 100 games and 1000 games). Although the medal grant rate is calculated, it is not particularly limited to such a configuration. For example, every time 50 games are played, the medal grant rate may be calculated based on the total number of medals and the total number of payouts bet for the last 100 games.

  (K) In the above embodiment, the medal grant rate is calculated when the number of games reaches a predetermined number. For example, when the number of medals bet reaches a predetermined number, the medal grant rate is changed. You may comprise so that it may calculate.

  (L) In the above-described embodiment, the display control device 111 is configured to be supplied with backup power from the power supply device 161. However, the display control device 111 is provided with a display power supply device corresponding to the display control device 111, and display control is performed. The device 111 may be configured to be supplied with backup power from the display power supply device. In that case, when the power is cut off, the voltage required for each control device (main control device 131, display control device 131) can be supplied more accurately.

  (M) In the above embodiment, a backup area may also be provided in the RAM 183 of the display control device 111. For example, a predetermined number of medals can be awarded when the pressing order of the stop switches 72 to 74 determined by the main control device 131 matches the pressing order of the stop switches 72 to 74 of the player. Even if a configuration is adopted in which the display control device 111 determines whether or not the navigation order is to be navigated by the auxiliary display unit 15 or the like, even if the power is shut off during the navigation, the display control device By saving the determined contents of 111 in the backup area, it is possible to return to the state before the power is shut off.

  (N) In the above embodiment, when the main controller 131 outputs medal information, the current gaming state (BB game, RB game, normal game) is determined, and how many medals are bet in which gaming state. For example, when the main control device 131 simply bets or pays out medals, the medal information is output to the display control device 111 or the like. In addition, the display control device 111 may determine the current gaming state and store medal information in a corresponding storage area in the medal information storage area 191. In this case, the main control device 131 only needs to execute processing generally performed conventionally, and an increase in the burden on the main control device 131 can be prevented.

  (O) In the above embodiment, a three-dedicated machine (usually a slot machine that requires three medals to execute one game) has been described. However, a star and a lever can be used with one or two medals bet. The above configuration may be adopted in a slot machine in which the reel rotates by operating the. In that case, a credit insertion switch for inserting two credited virtual medals at a time may be provided. Alternatively, a random number table may be selected such that the greater the number of bets, the higher the winning probability of winning combination. For example, the winning probability of a winning combination when three bets may be set to be higher than three times the winning probability of winning a winning combination when one bet is placed. Further, when such a configuration is adopted, for example, the measured value varies depending on the number of medals bet for each number of games (for example, a configuration in which a maximum of three medals can be bet per game is adopted). In addition, when three medals are bet, it is counted as one game, and when one medal is bet, it is counted as one third game).

  (P) The symbols of the reels 42L, 42M, and 42R are not limited to pictures, numbers, characters, and the like, but may be geometric lines or figures. In addition, the design can be configured by light, color, or the like, the design can be configured by a three-dimensional shape or the like, and the design can be configured by combining these. That is, it is sufficient that the symbol has a function as identification information (identification information).

  (Q) In the above-described embodiment, an example in which the slot machine 10 is embodied has been described. However, the present invention may be applied to a gaming machine in which a slot machine and a pachinko machine are combined. That is, in the slot machine, instead of the medal insertion and medal payout functions, a gaming machine having a ball insertion and ball payout function such as a pachinko machine may be used. For example, a ball receiving tray (an upper plate or the like) is provided, and a charging device that performs a loading process for taking in a game ball from the ball tray and a paying device that pays out a game ball to the ball receiving plate are provided. It is also possible to adopt a configuration in which the operation of the starting operation means is made effective when is inserted. If such a gaming machine is used in place of a slot machine, only a ball can be handled as a gaming medium in the gaming hall, so that it is a gaming medium that can be seen in current gaming halls where pachinko machines and slot machines are mixed. Problems such as the burden on equipment due to the separate handling of medals and balls and restrictions on the location of the gaming machine can be solved.

  (R) In the above embodiment, each of the reels 42L, 42M, and 42R of the reel unit 41 constitutes a rotating body, but the rotating body may have a configuration other than this. For example, you may comprise with a belt, a drum, etc. Further, for example, another mechanical reel configuration such as a type in which the belt rotates instead of rotating may be employed.
