Description

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

  An example of a gaming machine that obtains numerical information such as a random number and determines whether or not is correct is a slot machine. In the slot machine, a plurality of symbols are given to the outer peripheral portion of each reel, and a part of the symbols given to each reel is visible through the display window. Then, when the player inserts medals, an effective line is set according to the number of medals inserted, and then each reel starts to rotate when the player operates the start lever. , Each reel stops sequentially, and one game is completed. Inside the slot machine, when the start lever is operated with a medal inserted, numerical information is acquired at the timing when the start lever is operated, and the numerical information is used to play a role such as a bonus combination or a small combination. A hit / no-go decision is made. Then, when all reels stop rotating, a winning combination is made when the combination of the winning combination and the corresponding symbol stops on the active line. For example, when a small combination winning is established, a predetermined number of medals are paid out. Is given to the player, and when the bonus combination winning is established, the player is given a privilege that the gaming state shifts to a special gaming state advantageous to the player such as a big bonus game.

Here, as a configuration for generating numerical information, a configuration for generating numerical information using a numerical information counter and an oscillator is known. The oscillator outputs a clock signal to the numerical information counter at a fixed period, and the numerical information counter generates numerical information based on the input of the clock signal. Then, the numerical information generated at that time is acquired at the timing when the start lever is operated, and whether or not a bonus combination or a small combination is determined is determined using the acquired numerical information (see, for example, Patent Document 1). ).

  A game panel 30 for notifying the player of the game state is provided above the center of the front door 12. In the game panel 30, three vertically long display windows 31L, 31M, 31R are formed side by side. The display windows 31L, 31M, 31R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display windows 31L, 31M, 31R. The display windows 31L, 31M, and 31R may be combined into a single display window.

  As shown in FIG. 3, the inside of the housing 11 is vertically divided into two by a partition plate 40, and a reel unit 41 constituting variable display means is attached to the upper portion of the partition plate 40. The reel unit 41 includes a left reel 42L, a middle reel 42M, and a right reel 42R each formed in a cylindrical shape (annular shape). The reels 42L, 42M, and 42R may be configured as at least an endless belt, and are not limited to a cylindrical shape (annular shape). Each of the reels 42L, 42M, and 42R is rotatably supported so that the central axis thereof is the rotation axis of the reel. The rotation axes of the reels 42L, 42M, and 42R are arranged on the same axis extending in the substantially horizontal direction, and the reels 42L, 42M, and 42R correspond to the display windows 31L, 31M, and 31R on a one-to-one basis. . Accordingly, a part of the surface of each reel 42L, 42M, 42R is visible through the corresponding display windows 31L, 31M, 31R. Further, when the reels 42L, 42M, and 42R are rotated forward, the surfaces of the reels 42L, 42M, and 42R are projected as if moving from top to bottom through the display windows 31L, 31M, and 31R.

  Each of the reels 42L, 42M, and 42R is coupled to the stepping motors 61L, 61M, and 61R, and each of the reels 42L, 42M, and 42R is individually, that is, independently, driven by the stepping motors 61L, 61M, and 61R. Thus, it can be rotationally driven. 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 51 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 disc-shaped 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 motor plate 53 is provided with a reel index sensor (rotational position detection sensor) 55 in which a light emitting element 55a and a light receiving element 55b are held at a predetermined interval. On the other hand, the base end portion 56b of the sensor cut bun 56 extending in the radial direction is fixed to the boss reinforcing plate 52 integrated with the left reel 42L with a screw 57. The front end portion 56a of the sensor cut bun 56 is bent at a substantially right angle and is positioned so as to pass between both elements 55a and 55b of the reel index sensor 55. Each time the left reel 42L makes one rotation, the reel index sensor 55 detects the passage of the front end portion 56a of the sensor cut bun 56, and a detection signal is output to the main controller 131 described later each time the detection is made. Therefore, main controller 131 can confirm and correct the angular position of left reel 42L for each rotation 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), and the rotation position of the stepping motor 61L, that is, left The rotational position of the reel 42L is controlled.

  On each belt of each of the reels 42L, 42M, and 42R, a plurality of, specifically, 21 symbols are drawn 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. Based on the number of pulses from when the detection signal of the reel index sensor 55 is output, it is recognized which symbols are visible from the display windows 31L, 31M, and 31R, and arbitrary symbols are displayed on the display window. Control to make it visible from 31L, 31M, 31R can be performed.

  Of the symbols attached to 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 determined by the vertical lengths of the display windows 31L, 31M, and 31R. Is limited to a predetermined number. 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.

  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. In addition, numbers 0 to 20 are assigned to the reels 42L, 42M, and 42R, and these numbers are used for the main controller 131 to recognize the symbols that are visible from the display window. It is a number and is not actually attached to the reels 42L, 42M, 42R. However, in the following description, the number is used for explanation.

  The symbols include “Replay” symbol (for example, left belt 20th), “Bell” symbol (for example, left belt 19th), “Youth” symbol (for example, left belt 18th), “7” symbol (for example, (Left belt 17th), “Cherry” design (eg, left belt 13th), “Chance” design (eg, left belt 12th), “Watermelon” design (eg, left belt 9th), “Reach” design ( For example, there are nine types: the 6th left belt) and the “Lucky” symbol (for example, 1st left belt). As shown in FIG. 7, the number of symbols and the arrangement order of the various symbols are completely different in the belts wound around the reels 42L, 42M, and 42R.

  Each reel 42L, 42M, 42R of the reel unit 41 is an example of variable display means for variably displaying identification information, and constitutes a main display unit. However, the variable display means may have a configuration other than this as long as the symbol is variably displayed in the circumferential direction. For example, other mechanical reel configurations such as a type in which the belt is rotated instead of rotating may be used. In addition to the mechanical reel configuration, an electric display such as a liquid crystal display or a dot matrix display may be used. A device for variably displaying the identification information may be provided, and in this case, it is possible to give abundant variations in the display form.

  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 (middle 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. And, when the combination line that has been activated, that is, when the symbol is stopped in a predetermined combination on the activated line, a prize is awarded, and a payout process for a predetermined medal number or a bonus game such as a BB game that is in a special gaming state is awarded. Migration processing etc. are executed.

  FIG. 8 shows a combination of symbols for winning and the number of medals to be paid out when winning.

  Small prizes for which medals are paid out include a watermelon prize, a bell prize, and a cherry prize. When stopped alongside the “Watermelon” symbol, “Watermelon” symbol, and “Watermelon” symbol from the left on the active line, 15 medals are paid out as a watermelon prize, “Bell” symbol from the left, “Bell” on the active line In the case of stopping alongside the symbol and the “bell” symbol, eleven medals are paid out as a bell prize. When the “cherry” symbol on the left reel 42L stops on the active line, two medals are paid out as a cherry prize. That is, in the case of a cherry winning, any symbol that stops on the active line of the middle reel 42M and the right reel 42R may be any symbol. Therefore, when the “cherry” symbol stops at the position where the plurality of effective lines of the left reel 42L overlap (specifically, the upper stage or the lower stage), a cherry winning is established on each active line, and the overlapping effective The medal is paid out by multiplying the number of lines. As a result, in this embodiment, four medals are paid out.

  Further, there is a BB winning as a state transition winning in which the gaming state shifts. When the “7” symbol, “7” symbol, and “7” symbol are stopped from the left on the active line, the game state shifts to the BB game where the gaming state is the special gaming state as a BB winning. However, even if the “7” symbol stops along the left, middle and right on the active line, no medal is paid out. That is, when the combination of the “7” symbols is established on the active line, only the BB game is entered. In other words, it can be said that the “7” symbol is a state transition symbol for shifting the gaming state to the BB game.

  Furthermore, when the “replay” symbol, “replay” symbol, and “replay” symbol are stopped from the left on the active line, a re-game win is awarded. When the re-game winning is established, the medal payout and the state transition are not performed, but the player can play the next game without reducing the medals owned and without inserting medals.

  In addition, only when the gaming state is an RB game, which will be described later, when stopped alongside the “Replay” symbol, “Replay” symbol, “Chance” symbol from the left on the active line, and from the left on the active line When the “replay” symbol, “replay” symbol, and “lucky” symbol are stopped alongside, 15 medals are paid out as a JAC prize.

  In other cases, that is, when the “cherry” symbol of the left reel 42L does not stop on the active line and the combination of the symbols described above does not stop on the active line, the medal payout, the transition of the gaming state, etc. Not done at all. That is, the “chance” symbol and “lucky” symbol of the left reel 42L, the “cherry” symbol of the middle reel 42M and the right reel 42R, the “young” symbol and the “reach” symbol of each reel 42L, 42M, 42R Not involved at all. In other words, it can be said that each of the symbols is a no-benefits symbol unrelated to the privilege given to the player. As described above, each of the reels 42L, 42M, and 42R is provided with a bonus symbol related to winning such as a “bell” symbol and a non-privileged symbol irrelevant to winning such as a “young” symbol, for example. In the following, a combination of symbols corresponding to each prize is also referred to as a combination of winning symbols. For example, the BB symbol combination is a symbol BB winning combination, that is, a combination of “7” symbol, “7” symbol, and “7” symbol.

  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 or start operation means operated to start rotation of the reels 42L, 42M, and 42R, that is, to start variable display of symbols. The start lever 71 is a lever that is pushed by the hand when the player starts the game, and automatically returns to the initial position after the hand is released. Incidentally, the start lever 71 in the slot machine 10 is configured to require several tens of milliseconds until it automatically returns to the initial position after the hand is released. When the start lever 71 is operated when a predetermined number of medals are 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. That is, when the left stop switch 72 is operated, the rotation of the left reel 42L is stopped. When the middle stop switch 73 is operated, the rotation of the middle reel 42M is stopped and the right stop switch 74 is operated. In this case, the rotation of the right reel 42R is stopped. The stop switches 72, 73, 74 constitute stop operation means operated to stop the variable display of symbols 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 a medal as an investment value. The medal slot 75 constitutes an input means for inputting the investment value. Further, if attention is paid to the point that the medal insertion slot 75 is accompanied by the operation of directly inserting the medal by the player, it can be said that the medal insertion slot 75 constitutes a direct input means for directly inputting the investment value.

  The medals inserted from the medal insertion slot 75 are guided to either the storage passage 81 or the discharge passage 82 by the selector 84 as passage switching 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 in 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.

  A hopper device 91 as a payout means for giving a medal to a player is composed of a storage tank 92 for storing the medal and a payout device 93 for paying out the medal 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, 31R, there is provided a button-like first credit insertion switch 77 for inserting three virtual medals credited as investment values at a time. Further, on the left side of the first credit insertion switch 77, a second credit insertion switch 78 and a third credit insertion switch 79 are provided as button switches smaller than the switch 77. The second credit insertion switch 78 is for inserting two credited virtual medals at a time, and the third credit insertion switch 79 is for inserting one virtual medal. Each of the credit insertion switches 77 to 79, together with the medal insertion slot 75, constitutes an input means for inputting an investment value. Further, if the medal insertion slot 75 is accompanied by an operation of directly inserting a medal by the player, each credit insertion switch 77 to 79 is only accompanied by an operation of inserting a virtual medal based on the storage memory. It can also be said that it constitutes an indirect input means for indirectly inputting the investment value.

  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 settlement switch 80 is provided on the left side of the start lever 71. That is, the slot machine 10 has a credit function for storing and storing surplus inserted medals up to a predetermined maximum value (for 50 medals) and winning medals as virtual medals. The virtual medal is paid out as an actual medal when the settlement switch 80 is pressed while stored and stored. In this case, if paying attention to the function of paying out the credited virtual medal as an actual medal, it can be said that the checkout switch 80 constitutes a checkout operation means for actually paying out the stored game value.

  It should be noted that the surplus inserted medals up to a predetermined maximum value (for example, 50 medals) and the “credit mode” set to store and memorize the winning medals as virtual medals, the surplus inserted medals, In the case of a slot machine that can be switched to “direct mode” set so that the winning medal at the time of winning is paid out as an actual medal, the settlement switch 80 has a function as a changeover switch for mode switching. May be added. In this case, the settlement switch (changeover switch) 80 is turned on when pressed once, turned off when pressed again, and switched on / off every time a pressing operation is performed. When the settlement switch 80 is on, the credit mode is selected. When the settlement switch 80 is off, the direct mode is selected. If there are virtual medals when the credit mode is switched to the direct mode, the virtual medals corresponding to the virtual medals are paid out as real medals. Thereby, 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 settlement switch 80 constitutes a switching operation means for switching the input value and game value handling formats.

  Below the display windows 31L, 31M, and 31R of the game panel 30, a credit display unit 35 that displays the number of virtual medals stored and stored, and the remaining number of acquired medals that displays the number of remaining medals that can be acquired before the BB game is over. A display unit 36 and an acquired number display unit 37 for displaying the number of medals acquired at the time of winning 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. If a medal is inserted from the medal slot 75 at the start of the game, a bet is placed.

  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 middle 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, surplus medals exceeding three are stored inside the slot machine if the number of virtual medals stored and stored at that time is less than 50. At the same time, the number of virtual medals on the credit display unit 35 is added and displayed. On the other hand, when the number of virtual medals is 50 or reaches 50, the selector 84 switches from the storage passage 81 to the discharge passage 82, and the surplus medals are returned from the medal discharge port 17 to the medal tray 18. Is done.

  Further, when the stored number is displayed on the credit display unit 35, a virtual medal is inserted even when any of the first to third credit insertion switches 77 to 79 is pressed, and a bet is made. .

  When the third credit insertion switch 79 is pressed, the numerical value displayed on the credit display unit 35 is decremented by one as a virtual medal is inserted, and the first effective line display unit 32 is turned on. The middle line becomes the active line. When the second credit insertion switch 78 is pressed, two numerical values displayed on the credit display unit 35 as two virtual medals are inserted are subtracted, and the first valid line display unit 32 and the second The effective line display unit 33 is turned on, and a total of three combination lines become effective lines. When the first credit insertion switch 77 is pressed, three numerical values displayed on the credit display unit 35 are subtracted as three virtual medals are inserted, and all the effective line display units 32 to 34 are displayed. Lights up and a total of five combination lines become effective lines.

  In addition, when the virtual medal to be inserted when any of the first to third credit insertion switches 77 to 79 is pressed is not stored, for example, when the display of the credit display unit 35 is 2, the first credit For example, when the insertion switch 77 is pressed, all the numerical values in the credit display unit 35 are subtracted to 0, and a bet is placed for the virtual medal that can be inserted.

  On the upper part of the front door 12, there are an upper lamp 13 that lights up or flashes as the game progresses, and a pair of left and right sounds that make various sound effects as the game progresses and inform the player of the game state Speaker 14 and an auxiliary display unit 15 for giving various information to the player. In the present embodiment, the auxiliary display unit 15 is configured by a liquid crystal display for the purpose of diversifying display contents and increasing the display effect. However, other displays such as a dot matrix display may be used. Good. The auxiliary display unit 15 is for executing various display effects as the game progresses, and it can be considered that the game by the reels 42L, 42M, and 42R is caused by the main display unit. This is referred to as an auxiliary display unit 15. On the back surface of the auxiliary display unit 15, an upper lamp 13, a speaker 14, and a display control device 111 for driving the auxiliary display unit 15 are provided. The positions and numbers of the upper lamp 13 and the speakers 14 are not limited to those described above.

  A lower plate 16 on which a model name, a character related to a game, and the like are displayed is mounted above the medal tray 18. In addition, an ashtray 19 that can be reversed to the lower side on the front side is provided on the left side of the medal tray 18.

  A power supply box 121 is provided on the left side of the hopper device 91 inside the housing 11. The power supply box 121 includes a power switch 122, a reset switch 123, a setting key insertion hole 124, and the like. The power switch 122 is a start switch for supplying power to each unit including the main controller 131. The reset switch 123 is a switch for resetting an error state of the slot machine 10. Further, the setting key insertion hole 124 is used by a hole manager or the like to adjust the medal appearance. That is, the hall manager or the like can set the winning probability of the slot machine 10 by inserting the setting key into the setting key insertion hole 124 and turning it ON. The reset switch 123 is operated not only to reset the error state but also to change the winning probability of the slot machine 10.

  A main controller 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 provided in the power supply box 121, the CPU 151 includes a first clock circuit 154 that outputs a rectangular wave (first clock signal) having a predetermined frequency of 8.000 MHz, an input / output port 155, a role A random number generator 180 or the like for generating a random number used for determining whether or not is correct is connected via an internal bus. The main control device 131 functions as a main base incorporated in the slot machine 10.

  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. An inserted medal detection sensor 75a for detecting medals inserted from 75, credit insertion detection sensors 77a, 78a, 79a for individually detecting operations of the respective credit insertion switches 77, 78, 79, and an adjustment for detecting an operation of the adjustment switch 80. Detection sensor 80 a, reel index sensor 55 that individually detects the rotational position (origin position) of each reel 42, payout detection sensor 91 a that detects medals paid out from the hopper device 91, and reset detection sensor that detects the operation of the reset switch 123 123a, set to setting key insertion hole 124 Various sensors such as a setting key detection sensor 124a for detecting that a key is inserted and turned on are connected, and signals from these various sensors are output to the CPU 151 via the input / output port 155. ing.

  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 supply device 161 is connected to the input side of the main control device 131 via an input / output port 155. The power supply device 161 includes a power supply unit 161 a that supplies driving power to the electronic devices of the slot machine 10 including the main control device 131, a power failure monitoring circuit 161 b, and the like.

  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. For this reason, the power failure monitoring circuit 161b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 161a, and determines that the power supply is shut off when the drive voltage drops below, for example, 10 volts. Power outage 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. Although details will be described later, the power failure signal is also supplied to the display control device 111.

  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 even when the output voltage is reduced to less than 10 volts. As a time for outputting the stabilization voltage, a time sufficient for executing the power failure process by the main controller 131 is secured.

  On the output side of the main controller 131, each of the effective line display units 32, 33, 34, the credit display unit 35, the remaining acquired number display unit 36, the acquired number display unit 37, and the reels 42L, 42M, 42R is 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, a ROM, a RAM, and the like for driving these are integrated. Then, after receiving various commands to be described later 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-base that executes auxiliary control in relation to the main control device 131 that is a main base that manages and manages games. In other words, the sub-base is provided for voice, lamp, and display related to indirect games, thereby reducing the burden on the main base. 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. In addition to the RAM 153 for securing the area, although not shown, various processing circuits necessary for the slot machine 10 such as an interrupt circuit, a timer circuit, and a data transmission / reception circuit, as well known, and a credit counter for counting the number of credits are known. Various counters such as are built-in. The ROM 152 and the RAM 153 constitute a main memory as a storage unit, and a program for executing various processes shown in the flowcharts of FIG. 12 and subsequent figures is stored in the ROM 152 described above as a part of the control program.

  The RAM 153 is configured to hold (backup) data by being supplied with a backup voltage from the power supply device 161 provided in the power supply box 121 even after the power of the slot machine 10 is cut off. The RAM 153 stores a memory for temporarily storing various data, a setting information storage area 153a used when setting a winning probability, a game state such as a BB game, and various data used during a BB game. In addition to a BB information storage area 153b for playing, a game information storage area 153c for storing various data used in each game, a backup area is provided.

  The backup area is an area for storing the value of the stack pointer when the power is shut down due to the occurrence of a power failure or the like (including power shut down by operating the power switch 122; the same applies hereinafter). Yes, when the power failure is resolved (including power-on by operating the power switch 122; the same applies hereinafter), the state of the slot machine 10 can be restored to the state before power-off based on the backup area information. . Writing to the backup area is executed when the power is shut off by the power failure process (see FIG. 14), and the restoration of each value written in the backup area is executed in the main process (see FIG. 15) 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.

  Here, the connection relationship among the random number generator 180, the start detection sensor 71a, and the CPU 151 will be described in more detail based on the block diagram of FIG.

  On the input side of the random number generator 180, a second clock circuit 181 that outputs a rectangular wave (second clock signal) having a predetermined frequency of 7.915 MHz and a monitoring circuit 182 for monitoring the second clock circuit 181 are provided. It is connected. A CPU 151 is connected to the output side of the random number generator 180.

  The random number generator 180 is hardware having a counter 180a and a latch circuit 180b. The counter 180a is a 16-bit free-run counter that is incremented by 1 within the range of 0 to 65535, and returns to 0 after reaching the maximum value (that is, 65535). A second clock circuit 181 is connected to the counter 180a, and when the second clock signal from the second clock circuit 181 is input, the count value of the counter 180a is updated. The latch circuit 180b is configured by combining a plurality of D flip-flop circuits, and can latch (hold) the count value of the counter 180a. A monitoring circuit 182 is connected to the latch circuit 180b. When a latch signal from the monitoring circuit 182 is input, the count value of the counter 180a at that timing is latched in the latch circuit 180b, and the latched count value is A random number is output to the CPU 151.

  The monitoring circuit 182 is composed of a D flip-flop circuit. That is, the monitoring circuit 182 has a data terminal (D terminal) and a clock terminal (CLK terminal) as input terminals, and a positive logic output terminal (Q terminal) and a negative logic output terminal (Q bar terminal) as output terminals. is doing. A start detection sensor 71 a is connected to the D terminal via a waveform shaping circuit 183 and an input / output port 155, and a second clock circuit 181 is connected to the CLK terminal via an inverter 184. Further, the latch circuit 182 of the random number generator 180 is connected to the Q terminal, and the CPU 151 is connected to the Q bar terminal.

  The start detection sensor 71a outputs an operation signal when the start lever 71 is operated. More specifically, the start detection sensor 71a outputs an operation signal when the start lever 71 moves from the initial position, and stops outputting the operation signal when the start lever 71 returns to the initial position. The waveform shaping circuit 183 is configured by a Schmitt trigger circuit. A threshold is set in the waveform shaping circuit 183, and the waveform shaping circuit 183 sends a detection signal to the monitoring circuit 182 when the operation signal output from the start detection sensor 71a is larger than the voltage increase side threshold. The output of the detection signal is stopped when the operation signal is smaller than the voltage drop side threshold. That is, the waveform shaping circuit 183 is a circuit for shaping the rounds (rise delay and fall delay) of the operation signal output from the start detection sensor 71a. The waveform shaping circuit 183 may be connected between the input / output port 155 and the monitoring circuit 182, and the waveform shaping circuit 183 may be provided on the main controller 131.

  The monitoring circuit 182 operates the operation signal (more specifically, from the waveform shaping circuit 183 at the timing when the inverted second clock signal (inverted clock signal) is input to the CLK terminal (more specifically, the rising timing of the inverted clock signal). When a detection signal) is input, a latch signal is output to the random number generator 180 and a start signal is output to the CPU 151. These latch signal and start signal are continuously output until the operation signal is not input at the timing when the inverted clock signal is input to the CLK terminal. In other words, it can be said that the monitoring circuit 182 holds the input state of the operation signal until the inverted clock signal is input to the CLK terminal.

  The CPU 151 is connected to the latch circuit 180 b of the random number generator 180 and to the Q bar terminal of the monitoring circuit 182. The CPU 151 is connected to a first clock circuit 154 that outputs a first clock signal. The first clock circuit 154 outputs a rectangular wave having a predetermined frequency of 8.000 MHz and is configured not to synchronize with the second clock circuit 181. The CPU 151 performs various operations when the first clock signal is input. For example, it is determined whether or not a start signal is input based on the input of the first clock signal, and when the start signal is input, the count value latched in the latch circuit 180b is acquired as a random number. The determination of whether or not the start signal is input will be described in more detail. Since the CPU 151 is connected to the Q bar terminal of the monitoring circuit 182, the input signal from the Q bar terminal is switched from the H level to the L level. It is determined that a start signal has been input.

  Next, operations of the random number generator 180 and the monitoring circuit 182 will be described based on the timing chart of FIG.

  The signal output from the second clock circuit 181 rises from the L level to the H level at the timing t1, that is, the second clock signal is switched to the output present state (the signal output from the second clock circuit is the H level state). Then, in the random number generator 180, the count value of the counter 180a is updated to n. n is any value from 0 to 65535. In addition, since the second clock circuit 181 is connected to the CLK terminal of the monitoring circuit 182 via the inverter 184, in the monitoring circuit 182, the signal input to the CLK terminal changes from the H level to the L level at timing t1. Falling, inverted clock signal switches to no input state.

  The signal output from the second clock circuit 181 falls from the H level to the L level at the timing t2, that is, the second clock signal is not output (the signal output from the second clock circuit is in the L level). When the switching is performed, the monitoring circuit 182 causes the signal input to the CLK terminal to rise from the L level to the H level, and the inverted clock signal is switched to the input presence state. At this time, in the random number generator 180, the count value of the counter 180a is not updated, and the count value remains n.

  When the inverted clock signal is switched to the input presence state, the monitoring circuit 182 outputs a signal corresponding to the input state of the operation signal input to the D terminal at that time from the Q terminal and the Q bar terminal. Since the operation signal (H level detection signal) is not input at the timing t2, the latch signal and the start signal are not output from the Q terminal and the Q bar terminal. Since the start signal is output from the Q bar terminal (negative logic output terminal), only the start signal is an L level signal instead of the H level.

  After that, when the second clock signal is switched to the output enabled state at the timing of t3, the random number generator 180 updates the count value of the counter 180a to n + 1. As described above, the random number generator 180 sequentially updates the count value at the timing when the second clock signal is switched from the non-output state to the output state.

  When the start lever 71 is operated at the timing t4, the signal input to the D terminal of the monitoring circuit 182 rises from the L level to the H level, and the operation signal is switched to the input presence state. However, since the inverted clock signal is not input at the timing t4, the latch signal and the start signal remain in the no output state.

  When the inverted clock signal is switched from the no-input state to the input-present state at the timing t5, since the operation signal is input to the D terminal in the monitoring circuit 182, the output signal from the Q terminal is changed from the L level to the H level. At the same time, the output signal from the Q bar terminal falls from the H level to the L level. As a result, at the timing t5, the start signal and the latch signal are switched from the no output state to the output present state. The random number generator 180 latches the count value n + 1 of the counter 180a at this time in the latch circuit 180b as the latch signal from the monitoring circuit 182 switches from the no-input state to the input-present state. That is, when the start lever 71 is operated at the timing t4, the count value n + 1 is acquired as a random number not at the timing t4 but at the timing t5.

  At the timing of t6, the inverted clock signal is switched from the input present state to the no input state, but the output state of the latch signal and the start signal is not changed, and the output present state is maintained as it is. In other words, even if the inverted clock signal is switched from the input state to the no input state, both the latch signal and the start signal are held in the output state.

  Thereafter, when the inverted clock signal is switched from the non-input state to the input state at the timing t7, a latch signal and a start signal corresponding to the operation signal input state at the timing are output. Since the operation signal is in the input presence state at the timing t7, the latch signal and the start signal are continuously output in the output presence state.

  Here, in the random number generator 180, the count value of the counter 180a is updated at the timing (t1, t3, t6, etc.) when the second clock signal switches from the no-input state to the input-present state, and the count in the latch circuit 180b. The value is latched at a timing (t5) when the latch signal switches from the non-input state to the input state. The timing at which the latch signal switches from the no input state to the input present state is the timing at which the inverted clock signal switches from the no input state to the input present state, that is, the timing at which the second clock signal switches from the input present state to the no input state. is there. That is, in the random number generator 180, the count value is updated at the timing when the second clock signal switches from the no-input state to the input-present state, and at the timing when the second clock signal switches from the input-present state to the no-input state. The count value is latched. By adopting such a configuration, it is possible to prevent the count value update timing and the count value latch timing from being the same, and the latch timing comes while the count value is being updated, and the count value cannot be normally latched. It is possible to avoid problems.

  When the start lever 71 returns to the initial position at the timing t8, the operation signal input to the monitoring circuit 182 switches from the input present state to the no input state. Since the timing t8 is a timing at which the inverted clock signal switches from the input present state to the no input state, the output state of the latch signal and the start signal does not change at this timing. Then, it is detected that the operation signal is not input at a timing t9 when the inverted clock signal is switched from the no-input state to the input-present state, and both the latch signal and the start signal are switched from the output-present state to the no-output state. It should be noted that when the inverted clock signal is in the input present state (for example, timing t8 <timing t <timing t9), the operation signal is switched from the input present state to the no input state, or the inverted clock signal is in the no input state (for example, timing Even if the operation signal is switched from the input present state to the no input state at t7 <timing t <timing t8), both the latch signal and the start signal are switched from the output present state to the no output state at timing t9.

  By the way, when the configuration is such that the timing at which the operation signal is inputted is not always grasped but at the timing at which the inverted clock signal is inputted, the operation signal is switched to the input present state after the one inverted clock signal is inputted. If the operation signal is switched to the no-input state until the next inverted clock signal is input, there is a possibility that the operation of the start lever 71 cannot be accurately grasped. However, the start lever 71 in the slot machine 10 is configured to have several tens of milliseconds until the hand returns and returns to the initial position. When the start lever 71 is operated, the operation signal is at least several tens of milliseconds. The signal is input to the monitoring circuit 182. The clock frequency of the second clock signal output from the second clock circuit 181 is 7.915 MHz, and the period is about 126 nsec. In other words, the period in which the inverted clock signal is input in the monitoring circuit 182 is sufficiently shorter than the time interval required for the operation signal to switch from the input state to the input state. Therefore, it is possible to avoid a problem that the operation signal is skipped in the monitoring circuit 182 even though the operation signal is output from the start lever detection sensor 71a.

  Next, each control process executed by the CPU 151 in the main controller 131 will be described with reference to the flowcharts of FIGS. The CPU 151 performs various processes based on the input of the first clock signal from the first clock circuit 154. The processing of the CPU 151 is broadly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and an NMI terminal (non-maskable terminal). 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. 12 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. 13 is a flowchart of timer interrupt processing periodically executed by the main control device 131. A timer interrupt is generated by the CPU 151 of the main control device 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 capacity. This also applies to a processing program for power recovery processing described later.

  In step S301, it is determined whether command transmission has been completed. If the transmission has not been completed, this process is terminated and the process returns to the timer interrupt process to terminate the command transmission. In this way, it is determined whether or not the command transmission is completed at the initial stage of the power failure process, the transmission process is prioritized when the transmission is incomplete, and the power failure process is executed after the unit command transmission process is completed. By doing so, it is no longer 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 pointer 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, it means that the power failure state has been recovered. Therefore, 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. Incidentally, although detailed description is omitted, it is confirmed whether or not a power failure signal is output even under an infinite loop, and when the power failure signal is not output, the processing shifts to a main process described later.

  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 clear 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 is performed to enable the next timer interrupt to be set for the CPU 151 itself. In step S206, in order to rotate the reels 42L, 42M, and 42R, a stepping motor control process for driving the stepping motors 61L to 61R, which are the respective rotary drive motors, is performed. In step S207, sensor monitoring processing for reading the states of various sensors (see FIG. 9) such as the inserted medal detection sensor 75a and the payout detection sensor 91a connected to the input / output port 155 and monitoring whether the read result is normal or not. I do. In the sensor monitoring process, it is determined whether or not a start signal from the monitoring circuit 182 is input, that is, whether or not an L level signal from the monitoring circuit 182 is input. When the start signal is input, the start flag is set. When the start signal is not input, the start flag is cleared. In step S208, timer calculation processing for subtracting the value of each counter or timer is performed. In step S209, a counter process for outputting the bet number of medals and the result of counting the number of payouts to the external concentration terminal board 171 is performed.

  In step S210, command output processing for transmitting various commands such as a start command and a status command to be described later to the display control device 111 is performed. In step S211, segment data setting processing for setting segment data to be displayed on the credit display unit 35, the remaining acquired number display unit 36, and the acquired number display unit 37 is performed. In step S212, segment data set processing in the segment data setting processing is supplied to the display units 35 to 37, and segment data display processing for displaying corresponding numbers, symbols, and the like is performed. In step S213, port output processing for outputting data corresponding to the I / O device from the input / output port 155 is performed. In step S214, 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 S215, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

  FIG. 15 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. Etc.

  When these initialization processes are completed, in step S402, whether or not the setting key is inserted into the setting key insertion hole 124 and is turned ON, more specifically, whether or not the ON signal is received from the setting key detection sensor 124a. Determine. If the setting key has been turned ON, the process proceeds to step S403, and all data stored in the RAM 153 is cleared as a forced RAM clear process. In subsequent step S404, a winning probability setting process is performed.

  Here, the winning probability setting process will be described with reference to FIG. The slot machine 10 is prepared in advance with six stages of winning probabilities from “Setting 1” to “Setting 6”, and the winning probability setting process sets which of the winning probabilities is used to execute internal processing. It is a process to do.

  In step S501, the next timer interrupt is permitted. Thereafter, the current set value is read in step S502, and the current set value is displayed on the credit display unit 35 in step S503. However, in the process immediately after the setting key is inserted and turned ON, the data in the RAM 153 is cleared by the previous forced RAM clear process, so the set value displayed on the credit display unit 35 is “1”. is there.

  In step S504, it is determined whether or not the start lever 71 is operated. If the start lever 71 is not operated, setting update processing shown in steps S505 to S506 is performed. In step S505, it is determined whether or not the reset switch 123 has been operated. If the reset switch 123 is not operated, the process directly returns to step S503. If the reset switch 123 is operated, the set value is updated by 1 in step S506, and then the process returns to step S503. That is, in the setting update process, every time the reset switch 123 is operated, the setting value is updated by 1, and the updated setting value is displayed on the credit display unit 35. When the reset switch 123 is operated when the set value is “6”, the set value is updated to “1”.

  If the start lever 71 is operated in step S504, it is determined in step S507 whether or not the setting key is continuously turned on. If the ON operation of the setting key is continued, the process waits as it is, and if the ON operation is ended, the next timer interruption is prohibited in step S508. Thereafter, the set value is stored in step S509, data other than the set value stored in the RAM 153 is cleared in step S510, and this process is terminated.

  Returning to the description of the main process, after performing the winning probability setting process in step S404, a normal process for performing main control relating to the game is executed in step S405.

  On the other hand, when the setting key is not inserted in step S402, power recovery processing shown in step S406 and subsequent steps is performed. The power recovery process is a process for returning the state of the slot machine 10 to the state before the power is shut off. Therefore, in the power recovery process, it is necessary to first check whether the data in the RAM 153 is normal.

  Therefore, in step S406, it is determined whether or not the set value is normal. Specifically, when the set value is any one of 1 to 6, it is determined to be normal, and when it is 0 or 7 or more, it is determined to be abnormal. If the set value is normal, it is confirmed in step S407 whether or not a power failure flag is set. If the power failure flag is set, it is further confirmed in step S408 whether or not the RAM determination value is normal. Specifically, the checksum value of the RAM 153 is checked to check whether the value is normal, that is, whether the checksum value 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 it is determined in step S408 that the RAM determination value is normal, the process proceeds to step S409, where the stack pointer value stored in the backup area is written into the stack pointer of the CPU 151, and the stack state before the power is shut off. Return to the state. Next, in step S <b> 410, a power recovery command that tells execution of power recovery processing is transmitted to the display control device 111. After that, in step S411, the game state is stopped and automatic settlement setting storage processing is performed, and in step S412, 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 S413, 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.

  On the other hand, if any of step S406 to step S408 is NO, that is, the set value is abnormal, the power failure flag that is set when the power is shut off is not set, or the RAM determination value is abnormal, There is a high possibility that the data in the RAM 153 has been destroyed. In such a case, the operation prohibiting process shown in steps S414 to S416 is performed. As the operation prohibition process, first, the next timer interrupt process is prohibited in step S414, and in step S415, all output ports in the input / output port 155 are cleared, so that all actuators connected to the input / output port 155 are removed. Control to off state. Thereafter, in step S416, an error notification process for notifying the occurrence of an error to the hall manager or the like using the upper lamp 13 or the like is performed. This operation prohibition state is maintained until the above-described winning probability setting process is performed.

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

  First, in step S601, an interrupt permission process for permitting the next timer interrupt is performed. In step S602, a pre-start process for enabling a game is performed. In the pre-start process, the setting state of stopping and automatic checkout is stored in the RAM 153 and waits until the display control device 111 and the like finish initialization. When initialization of the display control device 111 and the like is completed, game management processing shown in steps S603 to S612 is performed.

  As the game management process, in step S603, data stored in the game information storage area 153c of the RAM 153 (for example, a random value used in the previous game) is cleared, and in step S604, a start waiting process is performed.

  In the start waiting process, it is determined whether or not a re-game winning is established in the previous game. If a re-game winning is established, an automatic insertion process for automatically inserting the same number of virtual medals as the previous bet number is performed, and an insertion completion command is set to end the start waiting process. Here, the insertion completion command is a command transmitted to the display control device 111 so as to grasp the completion of the automatic insertion. In the automatic insertion process, virtual medals are inserted without reducing the number of virtual medals displayed on the credit display unit 35. That is, when a re-game winning is established in the previous game, the player can play the current game without reducing the number of medals owned and without inserting medals. If the re-game winning is not established, a sensor abnormality confirmation process is performed to check whether an abnormality has occurred in the sensor reading result in the sensor monitoring process step S207 of the timer interruption process. If the error has occurred, the slot machine 10 is put into an error state and an abnormality occurrence process for notifying the occurrence of the error is performed. Although details will be described later, such an error state is maintained until the reset switch 123 is operated. If the sensor reading result is normal, it is determined whether or not the settlement switch 80 has been operated. If the settlement switch 80 has been operated, a medal return process for paying out the same number of medals as the credited virtual medals And set the checkout command. Here, the settlement command is a command transmitted to the display control device 111 so as to grasp that the credited virtual medal is being returned. After completion of the medal return process or when the settlement switch 80 is not operated, it is determined whether or not the medal insertion or the credit insertion switches 77 to 79 are operated. A medal insertion process for setting an effective line is performed, and an insertion command is set to end the start waiting process. Here, the insertion command is a command transmitted to the display control device 111 in order to grasp that a betting operation has been performed.

  After the start waiting process is completed, it is determined in step S605 whether or not the bet number of medals has reached a specified number (3 in the present embodiment). If the specified number has been reached, the start lever is further determined in step S606. It is determined whether 71 is operated and a start command is generated. Whether or not the start command has been generated is determined based on whether or not the start flag is set. When the start flag is set, it is determined that the start command has been generated. If the bet number has not reached the specified number or if no start command has been issued, the process returns to the start wait process in step S604, and the processes after the sensor abnormality confirmation process are performed.

  If a start command is generated, the process proceeds to step S607, where the medal path switching solenoid 83 is switched to a non-excited state to prohibit bet reception, and a start command is set in the subsequent step S608. Here, the start command is a command transmitted to the display control device 111 in order to grasp that a start command has been generated. Thereafter, the lottery process in step S609, the reel control process in step S610, the medal payout process in step S611, and the bonus game process in step S612 are executed in order, and the process returns to step S603.

  In the normal process, various commands such as the input completion command are only set in the ring buffer, and the command is not transmitted to the display control device 111. The command transmission to the display control device 111 is performed in the command output process S210 of the timer interrupt process described above.

  Next, the lottery process in step S609 will be described based on the flowchart of FIG.

  In step S701, a random number used when determining whether or not the winning combination is determined is acquired. More specifically, the random number generator 180 latches the count value at the timing when the latch signal from the monitoring circuit 182 is input, and outputs the latched count value to the CPU 151. The CPU 151 reads the input count value as a random number.

  Here, in the series of processing from step S208 to step S215 in the timer interrupt processing, the time required for performing these series of processing is input to the CPU 151 after the random number generator 180 latches the count value. It is configured so as to be longer than the time required for the operation. With this configuration, the random number acquisition timing (timing for performing the processing of step S701) can be delayed from the timing at which the count value latched in the current game is input to the CPU 151, and is latched in the current game. It is possible to reliably obtain the counted value as a random number.

  In step S702, a lottery table for determination of success / failure is selected based on the current setting state and gaming state of the slot machine 10. Here, the setting state of the slot machine 10 is any one of “setting 1” to “setting 6”. When “setting 1”, the lottery table having the lowest BB winning probability is selected, and when “setting 6” is set. The lottery table having the highest BB winning probability is selected. Here, the lottery table will be briefly described. FIG. 19 is a lottery table selected under the normal state of “Setting 1”. In the lottery table, the same number of index values IV as the number of winning combinations is set. That is, under the normal state, five types of winnings of replay, cherry, bell, watermelon, and BB can occur (see FIG. 8), so five index values IV of 1 to 5 are set. Each index value IV is uniquely associated with a winning combination, and a point value PV is set. In each lottery table in the slot machine 10, the point value PV corresponding to the BB combination is set larger as the lottery table has a higher set value.

  In step S703, the index value IV is set to 1, and in the subsequent step S704, a determination value DV used for determining whether or not the winning combination is determined. In the determination value setting process, a new determination value DV is set by adding a point value PV corresponding to the current index value IV to the current determination value DV. In the first determination value setting process, the random value created in step S701 is set as the current determination value DV, and a point value PV corresponding to 1 that is the current index value IV is added to the random value to obtain a new value. The determination value is DV.

  Thereafter, in step S705, whether or not the combination corresponding to the index value IV is determined. In the determination of whether or not a winning combination is made, it is determined whether or not the determination value DV exceeds 65535. If the determining value DV exceeds 65535, the winning flag corresponding to the index value IV at that time is set in step S706. Incidentally, when the winning flag is a small role winning flag or a re-game winning flag, these winning flags are reset after the game in which the corresponding winning flag is set (see step S603 of the normal process). On the other hand, when the winning flag is the BB winning flag, the BB winning flag is reset as one of the conditions that the combination of the BB symbols is established on the active line. That is, the BB winning flag may be valid for a plurality of games. In addition, in the success / failure determination of the winning combination after the next game carrying over the BB winning flag, the determination of whether or not the small combination or replay is made is performed, but the determination of whether or not the BB is related is not performed.

  If the determination value DV does not exceed 65535 in step S705, it means that the combination corresponding to the index value IV is lost. In such a case, 1 is added to the index value IV in step S707, and in the subsequent step S708, it is determined whether or not there is a role corresponding to the index value IV, that is, whether or not there is a role to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index values IV set in the lottery table. If there is a winning combination to be determined, the process returns to step S704 to continue the determination of winning combination. At this time, in step S704, the point value PV corresponding to the current index value IV is added to the determination value DV (that is, the current determination value DV) used for the determination of whether or not the previous combination is a correct determination value DV, In step S <b> 705, the winning combination determination is performed based on the determination value DV. Incidentally, when the lottery table shown in FIG. 19 is selected, the BB winning probability is about 1/300. On the other hand, the replay and small role winning probabilities are set higher than the BB winning probability, the replay winning probability is about 7.3, the bell winning probability is about 7.0, Cherry and watermelon winning The probability is 1/128.

  After the winning flag is set in step S706, or when it is determined in step S708 that there is no winning combination to be determined, it means that the winning determination of the winning combination is finished. In such a case, a set value command and a lottery result command are set in steps S709 and S710. Here, the set value command is a command transmitted to the display control device 111 in order to grasp the current set value, and the lottery result command is a display control device in order to grasp the result of the combination determination. 111 is a command transmitted to 111.

  Thereafter, in step S711, a slip table setting process for setting a slip table (stop table) for reel stop control is performed, and this process ends. Here, the slip table is a table in which it is determined how much the reel is slid (rotated) and stopped after the stop switches 72 to 74 are pressed. In other words, the slip table is a symbol that reaches the base point position (on the lower line in this embodiment) when the stop switches 72 to 74 are pressed, and a stop symbol that actually stops at the base point position. This is a stop data group with a defined relationship.

  Since this embodiment has a feature in the data structure related to the sliding table, this point will be described.

  In the slot machine 10, when the stop switches 72 to 74 are operated, when the reaching symbol is stopped as it is, when the corresponding reel is stopped after sliding for one symbol, it is stopped after sliding for two symbols. In this case, five patterns are prepared as a reel stop mode, in the case of stopping after sliding for three symbols, and for stopping after sliding for four symbols. This closely matches the timing at which the player operates the stop switches 72 to 74 and the symbol arrangement (hereinafter referred to as “stop appearance”) that stops in a visible range from each display window 32L, 32M, 32R. It is a device for associating. That is, by stopping the reels 42L, 42M, and 42R until the specified time (190 msec) has elapsed from the timing at which the stop switches 72 to 74 are operated, it is as if the stop outcome has been determined by the player's operation. It is possible to make a player have a good impression. In addition, by making it possible to slide up to 4 symbols, it becomes possible to stop combinations of symbols corresponding to the winning combination in the lottery on the active line as much as possible within the specified time. .

  There are five types of stop data relating to such a stop mode (no slip, one frame slip, two frames slip, three frames slip, four frames slip), five types for the middle reel 42M, and five types for the right reel 42R. is necessary. In this case, if the stop data related to each reel 42L, 42M, 42R is allocated in units of bits, 3 bits of stop data are required for each reel 42L, 42M, 42R, and cannot be stored in one byte.

  In this regard, in the present embodiment, since five types of stop data are required, the compressed data is created assuming that the stop data is collectively a hexadecimal number. That is, the stop data is configured as “(data of the left reel 42L) × 36 + (data of the middle reel 42M) × 6 + (data of the right reel 42R)”. In this case, the maximum number of stop data that can be prepared for each reel 42L, 42M, and 42R is six, and there are 6 × 6 × 6 = 216 combination patterns for the stop data as a whole. The maximum value that can be expressed is 256 or less. As a result, stop data for all the reels 42L, 42M, and 42R can be stored in one byte even though there are five types of stop data for each reel 42L, 42M, and 42R. Each reel 42L, 42M, 42R has 21 symbols, so that one slide table can be composed of 21 bytes, and the storage capacity of the main controller 131 can be reduced. It becomes. Incidentally, in this embodiment, about 60 types of 21-byte sliding tables are stored in the ROM 152 in advance.

  Further, in the slot machine 10 that stores each piece of stop data as compressed data, a predetermined decompression process is performed when each piece of stop data is used. Specifically, the compressed data corresponding to the symbol number of the reaching symbol is divided by “36” (= 6 × 6), and the obtained quotient is grasped as stop data of the left reel 42L. Further, the remainder obtained by the division is divided by “6”, and the obtained quotient is grasped as stop data for the middle reel 42M, and the remainder is grasped as stop data for the right reel 42R.

  Through the above-described processing, the CPU 151 can grasp stop data of each reel 42L, 42M, 42R as decompressed data. The stop data for all the reels 42L, 42M, and 42R may be configured so as to be accommodated in one byte. For example, the stop data may be combined into a quintic number to create compressed data. . As a condition for stopping data to fall within 1 byte, a value obtained by multiplying the maximum number that can be prepared as stop data for each reel 42L, 42M, 42R may be 256 or less. Therefore, the maximum number of stop data that can be prepared for each reel 42L, 42M, 42R is not necessarily the same. For example, even when 6 types of stop data can be prepared for the left reel 42L, 8 types for the middle reel 42M, and 4 types of stop data for the right reel 42R, the combination pattern of the entire stop data is 6 × 8 × 4 = 192. Therefore, the maximum value that can be expressed in 1 byte is 256 or less, so that stop data for all reels 42L, 42M, and 42R can be stored in 1 byte. Incidentally, in such a case, the compressed data is “(data of the right reel 42R) × 48 + (data of the middle reel 42M) × 6 + (data of the left reel 42L)”. The quotient obtained by dividing the compressed data to be divided by “48” is used as stop data for the right reel 42R, and the quotient obtained by dividing the remainder obtained by dividing by “6” is the stop for the middle reel 42M. The remaining data is grasped as stop data of the left reel 42L.

  FIG. 20 is an example of the sliding table that is set when the watermelon symbol is stopped on the active line. The symbol having the number of slips of 0 is a symbol that actually stops on the lower line. For example, if the left stop switch 72 is pressed while the “bell” symbol which is the seventh symbol of the left reel 42L has reached the lower line, the left reel 42L stops without slipping and becomes the ninth symbol. The “watermelon” symbol stops on the upper line. In addition, a symbol with a number whose slip number is not 0 means that the reel slides by the number of symbols described. For example, when the left stop switch 72 is pressed while the “replay” symbol which is the eighth symbol of the left reel 42L has reached the lower line, the left reel 42L slides by one symbol and becomes the ninth symbol. The “watermelon” symbol stops on the lower line. That is, if a stop switch is pressed when a symbol with a number of non-slip numbers reaches the lower line, the corresponding reel slides until a symbol with a zero slip number reaches the lower line. Stop. Thus, in the sliding table, the number of slips when the stop switches 72 to 74 are pressed at the timing when the symbols attached to the reels 42L, 42M, and 42R reach the lower line is set for each symbol number. Yes. For example, stop data with a left slip number of 2, a middle slip number of 0, and a right slip number of 3 for symbol number 0 is defined as 1-byte compressed data. The table is configured.

  As shown in FIG. 21, in the slip table setting process, first, in step S801, it is determined whether or not the BB winning flag is set. If the BB winning flag is not set, the process proceeds to step S802, and the first winning number uniquely corresponding to the winning flag is set in the winning number storage area provided in the game information storage area 153c. The winning number is the number used when setting the slip table. When the first winning number is set, the winning flag is not set or only one winning flag is set. Means. In the subsequent step S803, a sliding table uniquely determined from the value of the first winning number is set in the sliding table storage area provided in the game information storage area 153c, and this process ends. At this time, in the slot machine 10, the symbol corresponding to the winning flag of the middle reel 42M and the right reel 42R is medium so that the symbol corresponding to the winning flag of the left reel 42L stops at either the upper line or the lower line. Set the slide table set to stop on the line. If the winning flag is not set, a slip table in which no winning mode is established is set.

  The sliding table shown in FIG. 20 is a sliding table that is set based on the first winning number when the watermelon winning flag is set. In other words, it can be said that this is the sliding table that is set first when the watermelon winning flag is set. In such a sliding table, for example, when the middle stop switch 73 is pressed while the “cherry” symbol, which is the fourth symbol of the middle reel 42M, has reached the lower line, the middle reel 42M stops without slipping, The “Watermelon” symbol which is No. 5 symbol stops on the middle line. When the middle stop switch 73 is pressed while the “watermelon” symbol, which is the fifth symbol of the middle reel 42M, has reached the lower line, the middle reel 42M slides by three symbols and becomes the eighth symbol. The “reach” symbol stops on the lower line, and the “watermelon” symbol, the ninth symbol, stops on the middle line. The same applies to the right reel 42R. For example, when the right stop switch 74 is pressed while the “watermelon” symbol, which is the fourth symbol of the right reel 42R, has reached the lower line, the right reel 42R has three symbols. The “reach” symbol as the 7th symbol stops on the lower line, and the “watermelon” symbol as the 8th symbol stops on the middle line. As described above, the “watermelon” symbol is set to stop on the middle line for the middle reel 42M and the right reel 42R.

  However, the left reel 42L is set so that the “watermelon” symbol stops on either the upper line or the lower line. That is, if the left stop switch 72 is pressed while the 7th “bell” symbol is on the lower line, the 9th “watermelon” symbol stops on the upper line and the 8th “replay” If the left stop switch 72 is pressed while the symbol or the number 9 “watermelon” symbol reaches the lower line, the number 9 “watermelon” symbol stops on the lower line. This is a device for diversifying the stop output in consideration of the fact that the stop switches 72 to 74 are generally operated to stop the rotation in the order of the left reel 42L → the middle reel 42M → the right reel 42R. .

  Even when the sliding table is set for the first time, depending on the timing when the stop switch is pressed, the “watermelon” symbol may not stop on the active line, and so-called missing may occur. This is because the range that can be slid is pre-determined within 190 msec (maximum of 4 symbols) from the timing when the stop switch is pressed, and then reaches the lower line from the “watermelon” symbol that has reached the lower line. This is because the interval to the “watermelon” symbol to be set is set to a distance of 5 symbols or more. For example, in the case of the middle reel 42M, from the “Watermelon” symbol of No. 5 to the “Watermelon” symbol of No. 9 is only 3 symbols separated, from the “Watermelon” symbol of No. 9 to the “Watermelon” symbol of No. 5 Are separated by 16 symbols. For this reason, for example, if the middle stop switch 73 is pressed when the 11th “replay” symbol of the middle reel 42M has reached the lower line, even if the middle reel 42M is slid by four symbols, the “watermelon” "The symbol cannot be stopped on the active line." In the slot machine 10, in addition to the “watermelon” symbol, the “7” symbol and the “cherry” symbol are set at intervals of five symbols or more. That is, in the case of a watermelon prize, a BB prize, or a cherry prize, a failure may occur depending on when the stop switch is pressed.

  Returning to the description of the slip table setting process, if it is determined in step S801 that the BB winning flag is set, it is further determined in step S804 whether another winning flag is set. If no other winning flag is set, it means that only the BB winning flag is set. Therefore, the processing in steps S802 to S803 described above is performed, and this processing is terminated. On the other hand, when another winning flag is set, it means that the player has won a small role or replay with the BB winning flag carried over. In such a case, the process proceeds to step S805, and the second winning number uniquely corresponding to the set winning flag is set in the winning number storage area of the game information storage area 153c. When the second winning number is set, it means that the BB winning flag and the small role winning flag or the replay winning flag are set. In the subsequent step S806, a sliding table uniquely determined from the value of the second winning number is set in the sliding table storage area of the game information storage area 153c, and this process ends. At this time, the slot machine 10 sets a sliding table set so that a symbol corresponding to at least one of the BB winning flag and the other winning flag stops on any one of the active lines. More specifically, when the other winning flag is a re-game winning flag, a sliding table is set so that the “replay” symbol has priority over the “7” symbol and stops on the active line. On the other hand, when the other winning flag is the small role winning flag, the “7” symbol is preferentially stopped on the active line, and the “7” symbol is not stopped on the active line, A sliding table set so that the symbol corresponding to the winning flag stops on the active line is set. Further, when the other winning flag is a bell winning flag which is a small role winning flag, in addition to the above-described setting, both the “7” symbol and the “bell” symbol can be stopped on the active line. If there is, a sliding table set so that both the “7” symbol and the “bell” symbol stop on the active line is set.

  Next, the reel control processing in step S610 will be described based on the flowchart of FIG. In order to facilitate understanding, the description will be made in accordance with the progress of the actual game and will be described with reference to the symbol arrangement of FIG. 7 as appropriate.

  In the reel control process, first, in step S901, a rotation start process for starting rotation of the reels 42L, 42M, and 42R is performed.

  In the rotation start process, as shown in the flowchart of FIG. 23, it is confirmed whether or not a predetermined wait time (eg, 4.1 seconds) has elapsed since the reel started rotating in the previous game in step S1001. To do. If not, in step S1002, a wait wait command is set and waits until the wait time elapses. Here, the wait-wait command is a command transmitted to the display control device 111 so as to grasp that the wait time has not elapsed. If the wait time has elapsed, the wait time for the next game is reset in step S1003. Thereafter, in step S1004, a wait end command is set, and in subsequent step S1005, the bet number of medals to be output to the external concentration terminal board 171 is set in the counter processing S209 of the timer interruption processing. Here, the wait end command is a command transmitted to the display control device 111 in order to grasp that the wait time has elapsed. In step S1006, a motor control initialization process is performed for setting rotation start information in the motor control storage area provided in the game information storage area 153c. By performing this process, the acceleration process of the stepping motors 61L to 61R is started in the stepping motor control process S206 of the timer interrupt process, and the reels 42L, 42M, and 42R start to rotate. For this reason, even if the player bets a specified number of medals and operates the start lever 71, the reels 42L, 42M, and 42R may not immediately start rotating.

  In step S1007, a rotation information command is set. Here, the rotation information command is a command transmitted to cause the display control device 111 to grasp the rotation state of each reel 42L, 42M, 42R. In step S1008, it is determined whether or not each of the reels 42L, 42M, and 42R is rotating at a constant speed at a predetermined rotation speed. If not, the reels 42L, 42M, and 42R rotate at a constant speed. Wait until. Thereafter, when each of the reels 42L, 42M, and 42R is rotated at a constant speed, the process proceeds to step S1009, a constant speed rotation command is set, and this process is terminated. Here, the constant speed rotation command is a command transmitted to cause the display control device 111 to grasp that the rotation speeds of the reels 42L, 42M, and 42R are constant. In addition, when the reels 42L, 42M, and 42R are rotated at a constant speed, the CPU 151 indicates that the stop operation can be performed by lighting the lamps (not shown) of the stop switches 72 to 74. To inform.

  Returning to the description of the reel control process, in step S902, it is determined whether or not a start command is generated, more specifically, whether or not a start flag is set. If the start flag is set, Wait until the start flag is cleared.

  Incidentally, as a situation where it is determined that the start command is generated in step S902, if the start lever 71 remains pressed from the processing timing of step S606 to the processing timing of step S902, the processing of step S606 is performed. When the start lever 71 is operated again after a short time, there may be a case where some abnormality occurs in the monitoring circuit 182 or the like and the start signal remains output.

  If no start command has been generated, the process proceeds to step S903, where one of the stop switches 72 to 74 is operated to generate a reel stop command, more specifically, from the stop detection sensors 72a to 74a. It is determined whether or not an ON signal is received. If no stop command is generated, the system waits until a stop command is generated.

  If any of the stop switches 72 to 74 is operated in step S903 and a stop command is generated, the process proceeds to step S904, and whether or not the current stop command is the third stop command, that is, only one reel rotates. It is determined whether or not the stop switch has been operated during the operation. If any of the stop switches 72 to 74 is operated while all the reels 42L, 42M, and 42R are rotating, it means that the current stop command is the first stop command. In such a case, a negative determination is made in step S904, and a slip table first change process is performed in step S905. The first sliding table changing process is a changing process of the sliding table that is performed before the reels are stopped based on the generation of the stop command.

  In the first change process of the slip table, as shown in the flowchart of FIG. 24, it is determined in step S1101 whether or not the current stop command is the first stop command. Since the current stop command is the first stop command, the first stop change process shown in steps S1102 to S1108 is performed. In the first stop change process, it is confirmed which stop switch is operated in step S1102, and in step S1103, it is determined whether the operated stop switch is the left stop switch 72 or not. If the left stop switch 72 has been operated, the present process is terminated without changing the sliding table. This is because the slip table is set on the assumption that the left stop switch 72 is operated first in the previous slip table setting process (see FIG. 21).

  On the other hand, when a stop switch other than the left stop switch 72 is operated, the stop switches are operated in an order different from the assumed order (that is, the order of the left stop switch 72 → the middle stop switch 73 → the right stop switch 74). Means. In such a case, the process proceeds to step S1104, and the winning number set in the winning number storage area of the game information storage area 153c is confirmed. In a succeeding step S1105, it is determined whether or not a re-game is won from the confirmed winning number. Specifically, it is determined whether or not the confirmed winning number is a first winning number meaning a re-game winning or a second winning number meaning a re-game winning and a BB winning. If replay is won, the process proceeds to step S1106, and the slide table set in the slide table storage area of the game information storage area 153c is changed to a winning confirmation slide table for establishing a replay winning. This process ends. Here, the winning confirmation sliding table is a sliding table for avoiding the occurrence of so-called omission that a winning corresponding to the set winning flag is not established.

  FIG. 25 is a winning confirmation sliding table set when the re-game is won. In such a slip table, the “replay” symbol of the left reel 42L stops on the upper line, the “replay” symbol of the middle reel 42M stops on the middle line, and the “replay” symbol of the right reel 42R on the lower line. It is set to stop. In other words, the winning confirmation sliding table at the time of re-game winning is set so that the re-game winning is established on the lower right line. This is a contrivance for establishing a replay prize while avoiding the occurrence of a combination of combinations. Since the “cherry” symbol on the left reel 42L is a symbol that can be awarded by the symbol alone, if the left stop switch 72 is not operated for the first time, a winning combination may be made according to a combination of symbols such as a replay prize. A combination of winning combinations can occur between what is established and the cherry winning that is achieved by the left reel 42L alone. Specifically, when the “replay” symbol of the left reel 42L is stopped on the lower line in a situation where the “replay” symbols of the middle reel 42M and the right reel 42R are stopped on the lower line. Since the “cherry” symbol, which is the fifth symbol, stops on the upper line, a combination of a combination in which a re-game winning and a cherry winning are simultaneously formed occurs. However, since both the re-game and the cherry are not won in the previous lottery process, it is necessary to avoid a contradiction in which a combination of combinations occurs. Therefore, when a stop switch other than the left stop switch 72 is operated for the first time, by setting a winning confirmation sliding table on which a replay winning is established on the lower right line, Winnings can be established.

  If it is determined in step S1105 that the re-game is not won, it is determined whether or not only the bell win is made in step S1107. Specifically, the winning number confirmed in step S1104 is the first winning number indicating the bell winning. To see if it matches. If only the bell is won, the process proceeds to the above-described step S1106, and the slide table set in the slide table storage area of the game information storage area 153c is changed to a winning determination slide table for establishing a bell winning. Then, this process ends. Although a detailed description is omitted, the winning decision sliding table at the time of winning the bell is set so that the bell winning is established on the middle line. This is a contrivance for establishing a bell prize while avoiding the occurrence of a combination of combinations. For example, when the “bell” symbol of the seventh reel of the left reel 42L is stopped on the upper line in a situation where the “bell” symbols of the middle reel 42M and the right reel 42R are stopped on the upper line, the lower line Since the “cherry” symbol, which is the fifth symbol, is stopped above, a combination of a combination in which a bell winning and a cherry winning are simultaneously formed occurs. However, since both the bell and cherry are not won in the previous lottery process, it is necessary to avoid the contradiction in which the combination of combinations occurs. Therefore, when a stop switch other than the left stop switch 72 is operated for the first time, a bell winning combination is established while avoiding compounding of the combination by setting a winning decision sliding table on the middle line. It becomes possible to make it.

  If a negative determination is made in step S1107, that is, if a re-game such as BB is won and a role other than the bell is won, or if any role is not won, the process proceeds to step S1108, and the game information storage area 153c The slip table set in the slip table storage area is changed to an irregular push slip table that uniquely corresponds to the winning number and the operated stop switch, and the process is terminated. In the slot machine 10, as with the slip table set in the slip table setting process, the slide table in which a plurality of positions where the symbol corresponding to the winning flag can be stopped is set for the middle reel 42M and the right reel 42R, respectively. It is prepared. When a stop switch other than the left stop switch 72 is first operated, the stop switch operated from the slide table in which a plurality of positions where the symbol corresponding to the winning flag can be stopped is set on the left reel 42L. Change to a slide table that has been set multiple times for the corresponding reel. This is a contrivance for reducing the frequency of occurrence of missing items. The slip table shown in FIG. 20 will be described as an example. For example, when the middle stop switch 73 is operated at the timing when the “watermelon” symbol, which is the ninth symbol of the middle reel 42M, reaches the lower line, The 12th “Youth” symbol stops on the lower line and the “Watermelon” symbol does not stop on the active line. That is, when the middle reel 42M is stopped based on the sliding table shown in FIG. 20, although the middle stop switch 73 is operated at a timing at which the “watermelon” symbol can be stopped on the effective line, You will miss the watermelon prize. Therefore, in order to suppress the occurrence of such a problem, when a stop switch other than the left stop switch 72 is operated for the first time, the irregular push sliding table is changed.

  After the first change process of the sliding table is completed, in step S906, the symbol number of the reaching symbol that has reached the lower line at this timing is confirmed. Specifically, the symbol number of the reaching symbol reaching the lower line is confirmed by the number of pulses from the time when the detection signal of the reel index sensor 55 is output. In the subsequent step S907, the slip amount of the reel to be stopped this time is calculated from the compressed data of the symbol number corresponding to the reaching symbol among the slip tables set in the slip table storage area of the game information storage area 153c, and the process proceeds to step S908. Determine the symbol number of the symbol to actually stop on the lower line. In step S909, it is determined whether or not the symbol number of the reaching symbol of the reel to be stopped this time is equal to the symbol number of the stop symbol. If they are equal, a reel stop process for stopping the rotation of the reel is performed in step S910. Do. Thereafter, in step S911, a rotation information command is set so that the display control device 111 can grasp the current rotation state of each reel 42L, 42M, 42R, and in step S912, a stop symbol command is set. Here, the stop symbol command is a command transmitted to the display control device 111 so as to grasp a symbol stopped in a range (upper, middle, lower) visible from the display window. In step S913, it is determined whether all reels have stopped. When the above-described processing of steps S904 to S912 is performed based on the first stop command, the two reels are still rotating. In such a case, a negative determination is made in step S913, and a second smooth table change process is performed in subsequent step S914. The sliding table second changing process is a sliding table changing process performed after the reels are stopped.

  Here, the second change process of the slip table will be described with reference to the flowchart of FIG. In the second change process of the slide table, it is determined in step S1201 whether or not the currently set slide table is a winning decision sliding table. If the winning table is a winning decision sliding table, the process is terminated. If it is not the winning confirmation slide table, the process proceeds to step S1202, and the winning number set in the winning number storage area of the game information storage area 153c is confirmed. In the following step S1203, it is determined whether or not the confirmed winning number is the second winning number. If it is determined that the winning number is not the second winning number, the stopped symbol stopped on the lower line of the reel currently stopped in step S1204. Confirm the symbol number of. In step S1205, it is determined whether or not the symbol number of the stop symbol matches the symbol number of the changed symbol that is uniquely derived from the currently set slip table. This process is terminated without change. If the symbol number of the stop symbol matches the symbol number of the changed symbol, the process proceeds to step S1206, and the slip table set in the slip table storage area of the game information storage area 153c is changed to the slip table for line change. To end this process. In the slot machine 10, as with the slip table set in the slip table setting process, the slide table in which a plurality of positions where the symbol corresponding to the winning flag can be stopped is set for the middle reel 42M and the right reel 42R, respectively. It is prepared. Then, according to the stop symbol of the reel that has been stopped based on the first stop command, the position where the symbol corresponding to the winning flag can be stopped is changed to a slide table in which a plurality of other reels that are rotating are set. This is a contrivance for suppressing monotonization of the symbol arrangement (hereinafter referred to as “stopping appearance”) that stops in a visible range from each display window 32L, 32M, 32R.

  For example, when the left reel 42L and the middle reel 42M are configured to stop based on the sliding table shown in FIG. 20, the “watermelon” symbol of the left reel 42L stops on the upper line or the lower line, while the “ The “watermelon” symbol only stops on the middle line. However, when the “watermelon” symbol of the left reel 42L stops on the upper line, there remains room for a watermelon winning even if the “watermelon” symbol of the middle reel 42M stops on the upper line instead of the middle line. Similarly, when the “watermelon” symbol of the left reel 42L stops on the lower line, there remains room for a watermelon winning even if the “watermelon” symbol of the middle reel 42M stops on the lower line instead of the middle line. That is, when the left reel 42L and the middle reel 42M are stopped based on the sliding table shown in FIG. 20, the stoppage of the middle reel 42M is excessively restricted. Therefore, in the present slot machine 10, the stopped symbol of the stopped reel is confirmed, and the line changing slide table is changed according to the confirmation result. Specifically, if the “bell” symbol on the left reel 42L stops on the lower line and the “watermelon” symbol on the ninth reel stops on the upper line, the center on the upper or middle line The reel 42M is changed to a sliding table set to stop the "watermelon" symbol on the reel 42M. In addition, when the “watermelon” symbol which is the ninth symbol of the left reel 42L stops on the lower line, the slide table is set so that the “watermelon” symbol of the middle reel 42M stops on the middle line or the lower line. .

  Incidentally, in the slot machine 10, when the stop symbol and the changed symbol match, the slot table is changed to the following slip table. When the left reel 42L is stopped, the position where the symbol corresponding to the winning flag can be stopped is changed to a plurality of slide tables set for the middle reel 42M, and when the middle reel 42M is stopped, it corresponds to the winning flag. When the position where the symbol to be stopped can be changed to the slide table set for the right reel 42R and the right reel 42R is stopped, the position where the symbol corresponding to the winning flag can be stopped is set for the left reel 42L. Change to a smooth table.

  On the other hand, if an affirmative determination is made in step S1203, that is, if the confirmed winning number is the second winning number, in step S1207, it is determined whether or not the winning other than BB is a replay, and it is a replay. In this case, the processing from step S1204 to step S1206 described above is performed, and this processing is terminated. On the other hand, if the winning other than BB is the small winning combination, the processing at the second winning number is performed in step S1208, and this processing is terminated.

  In the second winning number process, as shown in the flowchart of FIG. 27, it is determined in step S1301 whether or not the winning other than BB is a bell winning. If it is a bell win, the process proceeds to step S1302, and it is determined whether there is a possibility that both a BB winning and a bell winning are established. Specifically, the symbol number of the stopped symbol on the lower line of the currently stopped reel is confirmed, and it is determined whether both “7” symbol and “Bell” symbol are stopped on the active line. To do. For example, when the “bell” symbol which is the 15th symbol of the left reel 42L is stopped on the lower line based on the first stop command, the “7” symbol which is the 17th symbol is stopped on the upper line. Therefore, at the stage where the left reel 42L stops based on the first stop command, there is a possibility that both the BB winning and the bell winning are established. In such a case, the process proceeds to step S1303, and the slide table set in the slide table storage area of the game information storage area 153c is set so that both the “7” symbol and the “bell” symbol can be stopped on the active line. This processing is terminated after changing to the simultaneous establishment sliding table. Specifically, when the “bell” symbol of the 15th symbol of the left reel 42L stops on the lower line based on the first stop command, the “bell” symbol of the 14th symbol of the middle reel 42M is on the lower line. When the “bell” symbol, which is the 14th symbol of the middle reel 42M, is stopped on the lower line based on the first stop command, the slide table set to stop is changed to the 15th symbol of the left reel 42L. Change to a sliding table set so that the “bell” symbol stops on the bottom line. In addition, when both the “7” symbol and the “bell” symbol cannot be stopped on the active line, these simultaneous establishment smooth tables are further configured so that the “7” symbol is stopped on the active line. If it is impossible to stop the “7” symbol on the active line, the “bell” symbol is set to stop on the active line.

  If a negative determination is made in step S1302, it is determined in subsequent step S1304 whether there is a possibility that a BB winning will be established, that is, whether the “7” symbol is stopped on the active line. If the “7” symbol is stopped on the active line, the process proceeds to step S1305, and the “7” symbol is stopped on the active line for the smooth table set in the smooth table storage area of the game information storage area 153c. The processing is terminated after changing to the BB winning slide table set as described above. If it is determined in step S1304 that there is no possibility that a BB winning will be established, the process proceeds to step S1306, and the slip table set in the slip table storage area of the game information storage area 153c is displayed with a “bell” symbol. The processing is terminated after changing to the bell winning slide table set to stop on the active line.

  If the winning combination other than the BB winning combination is not a bell in step S1301, it means that the winning combination is watermelon or cherry. In such a case, the process proceeds to step S1307, and it is determined whether or not there is a possibility that a BB winning will be established, that is, whether or not the “7” symbol is stopped on the active line. If the “7” symbol is stopped on the active line, the process proceeds to step S1308, and the “7” symbol is stopped on the active line for the smooth table set in the smooth table storage area of the game information storage area 153c. The processing is terminated after changing to the BB winning slide table set as described above. If it is determined in step S1307 that there is no possibility that a BB winning will be established, the process proceeds to step S1309, and the sliding table set in the sliding table storage area of the game information storage area 153c is selected as a winning combination other than BB. The symbol corresponding to (the “watermelon” symbol or the “cherry” symbol) is changed to the small winning prize sliding table set to stop on the active line, and this processing is terminated.

  As described above, when the corresponding reel is stopped based on the first stop command and the sliding table second change process is performed, the process returns to step S902, the start flag is cleared, and the stop corresponding to the rotating reel is returned. Wait until one of the switches is operated and the next stop command is generated.

  If any stop switch corresponding to the rotating reel is operated in step S903 and a stop command is generated, the process proceeds to step S904 to determine whether or not the current stop command is the third stop command. If the stop switch is operated when any one of the reels is stopped, it means that the current stop command is the second stop command. In such a case, a negative determination is made in step S904, and a slip table first change process is performed in step S905.

  In the first change process of the slip table, as shown in the flowchart of FIG. 24, it is determined in step S1101 whether or not the current stop command is the first stop command. Since the current stop command is the second stop command, the second stop change process shown in steps S1109 to S1114 is performed. In the second stop change process, it is determined in step S1109 whether or not the currently set slip table is a winning confirmation sliding table. If the winning table is a winning confirmation sliding table, the present process is terminated. If it is not the winning confirmation slide table, the process proceeds to step S1110 to check in which order the stop switch 72 to 74 are issued with the first stop command and the second stop command. In subsequent step S1111, it is determined whether or not the confirmation result is a forward push operation operated in the order of the left stop switch 72 → the middle stop switch 73. If the confirmation result is the forward push operation, the slide table is not changed. This process ends. This is because in the previous second change process of the slide table, when the left stop switch 72 is operated first, it is changed to a slide table that assumes that the middle stop switch 73 will be operated next. Even if the slide table is not changed in the second slide table change process, the slide table in which the symbol corresponding to the winning flag of the middle reel 42M stops on the middle line in the previous slide table setting process is set. Because it is.

  If it is determined in step S1111 that the operation is not a forward pressing operation, the process proceeds to step S1112 and the symbol number of the stopped symbol stopped on the lower line of the reel stopped based on the first stop command is confirmed. In step S1113, it is determined whether or not the symbol number of the stop symbol matches the symbol number of the changed symbol that is uniquely derived from the currently set slip table. If not, the slip table is changed. The process is terminated without any processing. If the symbol number of the stop symbol matches the symbol number of the changed symbol, the process proceeds to step S1114, and the slip table set in the slip table storage area of the game information storage area 153c is changed to the slip table for line change. The process ends. Specifically, in accordance with the stop symbols of the reels stopped based on the first stop command, a plurality of positions where the symbols corresponding to the winning flags can be stopped are set for the reels to be stopped based on the second stop command. Change to the sliding table. For example, when the right stop switch 74 is operated as the second stop command in a situation where the watermelon winning flag is set and the “watermelon” symbol of the left reel 42L is stopped on the upper line, a watermelon winning is established. The “watermelon” symbol of the right reel 42R may be stopped on the upper line or the lower line. Therefore, when the stop switch is operated in the order of the left stop switch 72 → the right stop switch 74, the “watermelon” symbol of the right reel 42R is changed to a sliding table set to stop on the upper line or the lower line. To do.

  After the first change process of the sliding table is completed, in step S906, the symbol number of the reaching symbol that has reached the lower line at this timing is confirmed. In the subsequent step S907, the slip amount of the reel to be stopped this time is calculated from the compressed data of the symbol number corresponding to the reaching symbol among the slip tables set in the slip table storage area of the game information storage area 153c, and the process proceeds to step S908. Determine the symbol number of the symbol to actually stop on the lower line. In step S909, it is determined whether or not the symbol number of the reaching symbol of the reel to be stopped this time is equal to the symbol number of the stop symbol. If they are equal, a reel stop process for stopping the rotation of the reel is performed in step S910. Do. Thereafter, in step S911, a rotation information command is set so that the display control device 111 can grasp the current rotation state of each reel 42L, 42M, 42R, and in step S912, it can be visually recognized from the display window by this reel stop processing. A stop symbol command is set to grasp the symbols stopped in the range. In step S913, it is determined whether all reels have stopped. When the processes of steps S904 to S912 described above are performed based on the second stop command, one reel is still rotating. In such a case, a negative determination is made in step S913, and a second smooth table change process is performed in subsequent step S914.

  Here, the second change process of the slip table will be described with reference to the flowchart of FIG. In the second change process of the slide table, it is determined in step S1201 whether or not the currently set slide table is a winning decision sliding table. If the winning table is a winning decision sliding table, the process is terminated. If it is not the winning confirmation slide table, the process proceeds to step S1202, and the winning number set in the winning number storage area of the game information storage area 153c is confirmed. In subsequent step S1203, it is determined whether or not the confirmed winning number is the second winning number. If it is determined that the winning number is not the second winning number, it is stopped on the lower line of the two reels currently stopped in step S1204. Check the symbol number of the stop symbol. In step S1205, it is determined whether or not the symbol number of each stopped symbol matches the symbol number of the changed symbol uniquely derived from the currently set slip table, and at least one of them does not match In this case, this process is terminated without changing the sliding table. If the symbol number of each stop symbol and the symbol number of each changed symbol coincide with each other, the process proceeds to step S1206, and the slip table set in the slip table storage area of the game information storage area 153c is changed to the slip table for line change. Then, this process ends. For example, when the watermelon winning flag is set and the “watermelon” symbol of the left reel 42L stops on the upper line and the “watermelon” symbol of the middle reel 42M stops on the middle line, “watermelon” of the right reel 42R. Change to a sliding table where the symbol stops on the lower line.

  On the other hand, if an affirmative determination is made in step S1203, that is, if the confirmed winning number is the second winning number, in step S1207, it is determined whether or not the winning other than BB is a replay, and it is a replay. In this case, the processing from step S1204 to step S1206 described above is performed, and this processing is terminated. On the other hand, if the winning other than BB is the small winning combination, the processing at the second winning number is performed in step S1208, and this processing is terminated.

  In the second winning number process, as shown in the flowchart of FIG. 27, it is determined in step S1301 whether or not the winning other than BB is a bell winning. If it is a bell win, the process proceeds to step S1302, and it is determined whether there is a possibility that both a BB winning and a bell winning are established. Specifically, confirm the symbol number of each stopped symbol on the lower line of the two reels that are currently stopped, and stop the “7” symbol and “Bell” symbol together on the active line. It is determined whether or not. In this embodiment, it is determined whether or not the “bell” symbol as the 15th symbol of the left reel 42L and the “bell” symbol as the 14th symbol of the middle reel 42M are stopped on the lower line. When these symbols are stopped on the lower line, the “bell” symbol is stopped side by side on the lower line, and the “7” symbol is stopped side by side on the upper line. Depending on the stop result, there is a possibility that both BB winning and Bell winning may be established. In such a case, the process proceeds to step S1303, and if the slide table set in the slide table storage area of the game information storage area 153c can be stopped on the upper line, the symbol “7” is displayed. If it is impossible to stop on the upper line, and if it is impossible to stop, the “bell” symbol is changed to a sliding table for simultaneous establishment that is set to stop on the lower line, and this process is terminated. .

  If a negative determination is made in step S1302, in the subsequent step S1304, it is determined whether or not there is a possibility that a BB winning will be established, that is, whether or not “7” symbols are stopped side by side on the active line. If “7” symbols are stopped side by side on the active line, the process advances to step S1305 to change to the BB winning slide table set so that the BB winning is achieved, and the process is terminated. If it is determined in step S1304 that there is no possibility that a BB prize will be established, the process proceeds to step S1306, where the bell winning slide table set so that a bell prize is established is changed and the process is terminated. To do.

  If the winning combination other than the BB winning combination is not a bell in step S1301, it means that the winning combination is watermelon or cherry. In such a case, the process proceeds to step S1307, and it is determined whether or not there is a possibility that a BB winning will be established, that is, whether or not “7” symbols are stopped side by side on the active line. If “7” symbols are stopped side by side on the active line, the process proceeds to step S1308, and the slide table set in the slide table storage area of the game information storage area 153c is set so that a BB winning is established. The process is terminated after changing to the BB winning slide table. If it is determined in step S1307 that there is no possibility that a BB winning will be established, the process proceeds to step S1309, and the sliding table set in the sliding table storage area of the game information storage area 153c is selected as a winning combination other than BB. And change to the small table winning slide table that is set so that the corresponding winning is established, and this processing is terminated.

  As described above, when the corresponding reel is stopped based on the second stop command and the slide table second change process is performed, the process returns to step S902, the start flag is cleared, and the stop corresponding to the rotating reel is returned. Wait until the next stop command is generated after the switch is operated.

  When a stop command corresponding to the rotating reel is operated in step S903 and a stop command is generated, the process proceeds to step S904, and it is determined whether or not the current stop command is a third stop command. If the stop switch is operated when two reels are stopped, it means that the current stop command is the third stop command. In such a case, an affirmative determination is made in step S904, and the flow proceeds to step S906 without performing the first change process of the slip table.

  In step S906, the symbol number of the symbol that has reached the lower line at this timing is confirmed. In the subsequent step S907, the slip amount of the reel to be stopped this time is calculated from the compressed data of the symbol number corresponding to the reaching symbol among the slip tables set in the slip table storage area of the game information storage area 153c, and the process proceeds to step S908. Determine the symbol number of the symbol to actually stop on the lower line. In step S909, it is determined whether or not the symbol number of the reaching symbol of the reel to be stopped this time is equal to the symbol number of the stop symbol. If they are equal, a reel stop process for stopping the rotation of the reel is performed in step S910. Do. In step S913, it is determined whether all reels have stopped. When the processes of steps S904 to S912 described above are performed based on the third stop command, all reels have stopped rotating. In such a case, an affirmative determination is made in step S913, a payout determination process is performed in step S915, and this process ends. The payout determination process is a process of setting a payout number of medals on the condition that a combination of winning symbols is arranged on an active line.

  In the payout determination process, as shown in the flowchart of FIG. 28, the active line is confirmed based on the current gaming state in step S1401. Although details will be described later, this is because the active line is changed from 5 lines to 1 line (medium line) when the game state shifts to the BB game. In step S1402, a combination of symbols on a predetermined effective line is derived from the symbol numbers of the stopped symbols stopped on the lower lines of the reels 42L, 42M, and 42R, and it is determined whether or not a winning is achieved in step S1403. To do. If a winning is established, the process proceeds to step S1404, and it is determined whether or not the winning combination matches the winning flag set in the lottery process. If the winning combination combination does not match the winning flag, the process proceeds to step S1405, and the slot machine 10 is set to an error state and an abnormality occurrence process for notifying the occurrence of an error is performed. Thereafter, in step S1406, it is determined whether or not the reset switch 123 has been operated, and waits until the reset switch 123 is operated. When the reset switch 123 is operated, the process returns from the error state and the subsequent processing is started. In other words, if the reset switch 123 is operated or if the winning combination combination matches the winning flag in step S1404, the winning combination combination is set in step S1407 and the game information storage area in step S1408. The number of payouts corresponding to the winning combination is set in the payout number storage area 153c. Thereafter, in step S1409, it is determined whether or not the payout determination has been completed for all active lines. If not, the process returns to step S1402. That is, in this embodiment, when three medals are bet and five effective lines are set, it is sequentially determined whether or not a winning is achieved for each effective line.

  For example, when the “cherry” symbol of the left reel 42L is stopped on the upper line, 2 is set as the scheduled payout amount in the processing of steps S1402 to S1408 for the upper line, and steps S1402 to S1408 for the lower right line. In the process, 2 is set again as the scheduled number of payouts. As a result, when the “cherry” symbol of the left reel 42L stops on the upper line, 4 is set as the expected payout number, and four medal payouts are performed in the medal payout process described later.

  If the payout determination has been completed for all active lines, a pay command is set in step S1410 and a pay line command is set in step S1411, and this process ends. Here, the winning command is a command transmitted to the display control device 111 so as to grasp which winning has been established, and the winning line command indicates which active line the winning has been established. This is a command transmitted to the display control device 111 for grasping.

  Next, the medal payout process in step S611 will be described based on the flowchart of FIG.

  In the medal payout process, first, in step S1501, it is determined whether or not the planned payout number stored in the payout number storage area is zero. If the planned payout number is 0, it means that it has been determined in the previous payout determination process S915 that a small winning combination has not been established. In such a case, the process proceeds to step S1502, and it is determined whether or not a re-game winning is established based on the winning combination set in the payout determination process. If the re-game winning is not established, the process is terminated as it is. If the re-game winning is established, a re-game setting process for changing the gaming state to the re-gaming state is performed in step S1503. In step S1504, a replay command is set, and this process ends. Here, the replay command is a command transmitted to the display control device 111 so as to grasp that the next game is a replay. In the start waiting process S604 described above, the automatic insertion process is performed when it is determined that the current gaming state is the re-gaming state.

  If the number of payouts is not 0 in step S1501, a payout start command is set in step S1505. Here, the payout start command is a command transmitted to the display control device 111 so as to grasp that the medal payout has started. In step S1506, it is determined whether or not the number of payouts counted by the payout number counter matches the planned payout number stored in the payout number storage area. If the number of payouts does not match the planned payout number, it is determined in step S1507 whether the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit has not been reached, 1 is added to the count value of the credit counter and the number of payouts in steps S1508 and S1510, respectively. After that, in step S1511, display unit change processing is performed in which the credit display unit 35 and the acquired number display unit 37 are each incremented by one.

  On the other hand, when the count value of the credit counter reaches the upper limit in step S1507, the medal payout rotating plate is driven in step S1509 to pay the medal from the hopper device 91 to the medal tray 18 through the medal discharge port 17. put out. In subsequent step S1510, 1 is added to the number of payouts according to the medal detection signal of the payout detection sensor 91a attached to the hopper device 91. Thereafter, in step S1511, a display unit changing process for adding 1 to the number of acquired number display unit 37 is performed.

  After performing a display part change process in step S1511, it returns to step S1506 again. When the number of payouts matches the planned payout number in step S1506, a payout end command is set in step S1512. Here, the payout end command is a command transmitted to the display control device 111 so as to grasp that the medal payout has ended. In step S1513, it is determined whether or not the current gaming state is a bonus game. If the current gaming state is a bonus game, the number of payouts is subtracted from the count value of a remaining acquisition number counter (to be described later) in step S1514, and the number of remaining acquisition number display unit 36 is subtracted. The process ends. Note that the process of subtracting the number of remaining acquisition number display part 36 may be performed in the display part changing process of step S1511.

  Next, the bonus game process of step S612 will be described based on the flowchart of FIG.

  Prior to the description of the bonus game process, the bonus game will be described. The BB game is composed of a plurality of RB games. The RB game is composed of 12 JAC games. A JAC game is a game in which only one bet is allowed, and is a game with a very high probability that a combination of JAC symbols is aligned on an active line, that is, the probability of establishment of a JAC prize. That is, in the JAC game, in step S605 of the normal process described above, if the bet number is 1, an affirmative determination is made that the number is a specified number. When a JAC winning is established in the RB game, the maximum number (15 in this case) of medals is paid out. When the JAC winning is established 8 times, the RB game is ended even before the JAC game is played 12 times. Also, the BB game ends when the number of medals paid out reaches a predetermined number (specifically, 400). When the number of medals paid out reaches a predetermined number during the RB game, not only the BB game but also the RB game is ended. This is a contrivance for suppressing the player's euphoria by giving an upper limit to the number of medals paid out during the BB game and ensuring the soundness of the game. Further, in the present embodiment, a combination of symbols to be transferred to the RB game is not set, and the structure is set to shift to the RB game immediately after the shift to the BB game and immediately after the RB game ends. Therefore, it can be said that the BB game is a game that continuously shifts to the RB game until a predetermined number of medals are paid out.

  In the bonus game process, first, in step S1601, it is determined whether or not the gaming state is a bonus game. When it is not during the bonus game, bonus symbol determination processing shown in steps S1602 to S1606 is performed.

  In this bonus symbol determination process, first, in step S1602, it is determined whether or not the BB winning flag is set. When the BB winning flag is set, the process proceeds to step S1603, and it is determined whether or not the BB winning is established based on the winning combination set in the payout determination processing S915. When a BB winning is established, a BB start process is performed in step S1604. In the BB start process, the BB winning flag is reset and the BB setting flag is set in the BB information storage area 153b to obtain a BB game which is a kind of bonus game. Further, 400 is set in a remaining acquisition number counter for counting the number of remaining medals that can be paid out during the BB game, and a process of displaying 400 on the remaining acquisition number display unit 36 is performed. Incidentally, whether or not the current gaming state is a bonus game is determined based on whether or not the BB setting flag is set. In subsequent step S1605, RB start processing is performed. In the RB start process, 8 is set in the remaining JAC winning counter for counting the number of possible JAC winnings, and 12 is set in the remaining JAC game counter for counting the remaining number of JAC games. Each counter such as a remaining acquisition number counter and a remaining JAC winning counter is provided in the BB information storage area 153b. After performing the RB start process, in step S1606, an RB command transmitted to the display control device 111 is set in order to grasp that the RB game is started.

  In step S1607, a status command is set. Here, the state command is a command transmitted to the display control device 111 in order to grasp the current gaming state. That is, if it is determined in step S1602 that the BB winning flag is not set, a state command indicating a normal game is set, and if it is determined in step S1603 that a BB winning is not established, BB is set. A state command indicating that the game is a carryover game is set. If the RB command is set in step S1606, a state command indicating that the game is a BB game is set. In the subsequent step S1608, a game number display process is performed, and this process is terminated. In the game number display process, when the current game state is not a BB game (RB game), a process of clearing the display of the remaining acquired number display unit 36, the acquired number display unit 37, and the like is performed.

  If the gaming state is a bonus game in step S1601, the process proceeds to step S1609, and it is determined whether or not a JAC winning has been established based on the winning combination set in the payout determination processing S915. If a JAC winning is established, the value of the remaining JAC winning counter is decremented by 1 in step S1610. After that, or when a JAC winning is not established in step S1609, one JAC game has been consumed. In step S1611, the value of the remaining JAC game counter is decremented by one. Subsequently, in step S1612, it is determined whether either the remaining JAC winning counter or the remaining JAC game counter has become zero. If any of them is 0, that is, if the JAC winning is established 8 times or the JAC game is digested 12 times, it means that the RB game end condition is established, so in step S1613 the remaining JAC winning a prize. RB end processing is performed to reset the counter and the remaining JAC game counter values. In a succeeding step S1614, it is confirmed whether or not the count value of the remaining acquisition number counter is zero. If it is not 0, it means that the number of medals paid out during the BB game has not reached the predetermined number and the end condition for the BB game is not satisfied. Therefore, the RB start process described above in step S1615. In step S1616, an RB command is set. Thereafter, a state command indicating that the game is a BB game is set in step S1607, and a game number display process is performed in step S1608, and this process is terminated.

  If neither the remaining JAC winning counter or the remaining JAC game counter is 0 in step S1612, that is, if the JAC winning is not yet established 8 times and the JAC game is not consumed 12 times, step S1612 is executed. Proceeding to S1617, it is confirmed whether or not the count value of the remaining acquisition number counter is zero. If it is not 0, it means that the number of medals paid out during the BB game has not reached the predetermined number and the BB game end condition is not satisfied, so that it is the BB game in step S1607. Is set, a game number display process is performed in step S1608, and the process ends. On the other hand, if the count value of the remaining acquisition number counter is 0, it means that the BB game end condition is satisfied, and therefore, the special game state end process shown in steps S1618 to S1619 is performed. In the special game state end process, first, in step S1618, the above-described RB end process is performed. Thereafter, in step S1619, BB end processing for clearing data in the BB information storage area 153b is performed. In addition, when the count value of the remaining acquisition number counter is 0 in step S1614, it means that the BB game end condition is satisfied, and therefore the BB end process is performed in step S1619. After the BB end process is performed, a state command indicating that the game is a normal game is set in step S1607, and a game number display process is performed in step S1608, and this process ends.

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

  A monitoring circuit 182 composed of a D flip-flop circuit is provided in the main controller 131, and the monitoring circuit 182 has a start detection sensor 71a connected to the D terminal and a second clock circuit 181 connected to the CLK terminal. A random number generator 180 was connected to the Q terminal, and a CPU 151 was connected to the Q bar terminal. In such a configuration, when the second clock signal is not output from the second clock circuit 181 due to a failure or the like, or when the second clock signal remains output, the second monitoring circuit 182 causes the second clock signal to be output. Since the input state of the clock signal (more specifically, the inverted clock signal) does not change, the start signal is not output to the CPU 151. Therefore, even if an operation signal is output from the start detection sensor 71a under these circumstances, the reels 42L, 42M, and 42R do not start rotating, and the game hall in which the player or the slot machine 10 is installed is disadvantageous. It can be avoided. When the second clock signal is not input to the random number generator 180 or remains input, in the configuration in which a game can be played after that, the winning combination determination is always performed using the same random number. This is because no prize is won for each game and the player suffers a disadvantage, or the same prize for each game is established and the game hall suffers a disadvantage.

  Further, in such a configuration, even if the player or a manager of the game hall where the slot machine 10 is installed operates the start lever 71, the reels 42L, 42M, and 42R do not start rotating. It is possible to notify that an abnormality has occurred. Therefore, it is possible to quickly find out that an abnormality has occurred in the second clock circuit 181, and the game hall in which the player or the slot machine 10 is installed suffers disadvantages due to the abnormality in the second clock circuit 181. Can be suitably avoided.

  Certainly, a monitoring means for monitoring whether or not the second clock circuit 181 periodically outputs the second clock signal is provided, and if the second clock signal is not periodically output, the CPU 151 generates an abnormality. Even when an abnormality occurs, such as informing the player, it is possible to notify a player, a game hall manager, or the like that some abnormality has occurred in the second clock circuit 181. However, with such a configuration, it becomes necessary to store a program for performing processing at the time of occurrence of abnormality in the main controller 131 or the CPU 151 itself, and there is a concern about an increase in storage capacity. Also, if any abnormality occurs in the monitoring means instead of the second clock circuit 181, the abnormality cannot be found despite the occurrence of the abnormality in the second clock circuit 181, and the game continues. There is also concern about the possibility of this being done.

  On the other hand, in the case of the above embodiment in which the start detection sensor 71a and the CPU 151 are connected via the monitoring circuit 182, the game is performed through the fact that the reels 42L, 42M, and 42R do not start rotating even though the start lever 71 is operated. It is possible to directly notify the person of the occurrence of the abnormality, and it is not necessary to perform processing at the time of occurrence of the abnormality on the CPU 151 side. In addition, if any abnormality occurs in the monitoring circuit 182 itself, the output state of the start signal and the latch signal will not change. It is possible to notify directly. Therefore, it is possible to reduce the chances that the player or the game arcade where the slot machine 10 is installed suffers disadvantages with a relatively simple configuration, while solving the above-mentioned concerns, when an abnormality occurs in the slot machine 10. .

  In addition to the CPU 151, a random number generator 180 is connected to the output side of the monitoring circuit 182. With this configuration, when the second clock signal is not output from the second clock circuit 181 due to a failure or the like, or when the second clock signal remains output, the monitoring circuit 182 A latch signal is not output to the random number generator 180. Therefore, it is possible to avoid unnecessarily latching the count value of the counter 180a under these circumstances.

  The second clock circuit 181 is connected to the CLK terminal of the monitoring circuit 182 via an inverter 184. With this configuration, the timing at which the second clock signal is input to the random number generator 180 and the timing at which the latch signal from the monitoring circuit 182 is input to the random number generator 180 are set to the cycle of the second clock signal. On the other hand, it can be shifted by a half cycle. As a result, the count value update timing and the count value latch timing can be prevented from being the same timing, and the latch timing has come while the count value is being updated, resulting in a problem that the count value cannot be latched normally. Can be avoided.

  Since the monitoring circuit 182 is provided separately from the CPU 151 in the main control device 131, it is possible to notify the abnormality of the slot machine 10 without the CPU 151 monitoring whether the second clock circuit 181 is normal. Therefore, it is possible to reduce the processing load of the CPU 151 and to eliminate the need for a program related to the monitoring control of the second clock circuit 181 and to suppress an increase in the storage capacity of the CPU 151.

  Furthermore, even when some abnormality occurs in the monitoring circuit 182 itself instead of the second clock circuit 181, the abnormality can be easily found. That is, when any abnormality occurs in the monitoring circuit 182, the output state of the start signal and the latch signal is constant regardless of the input state of the operation signal or the second clock signal. This is because the reels 42L, 42M, and 42R do not start rotating despite the player operating the start lever 71, or the start signal is output even though the player does not operate the start lever 71. It leads to the occurrence of an abnormal event such as being in a state where it has been done. Therefore, it becomes possible for a player, a game hall manager, or the like to easily discover that some abnormality has occurred in the slot machine 10. As a result, when an abnormality occurs in the slot machine 10 while avoiding the occurrence of a problem such as an abnormality of the second clock circuit 181 being not found due to an abnormality occurring in the monitoring circuit 182. Opportunities for the player or the game hall where the slot machine 10 is installed to be disadvantageous can be reduced.

  A first clock circuit 154 that inputs a clock signal to the CPU 151 and a second clock circuit 181 that inputs a clock signal to the random number generator 180 are provided separately, and the clock signals output from these clock circuits 154 and 181 are synchronized. Not configured. With this configuration, the timing at which the latch circuit 180b latches the count value in the random number generator 180 and the acquisition timing at which the CPU 151 acquires the random number from the latch circuit 180 are synchronized, and the CPU 151 cannot acquire the random number normally. It is possible to avoid problems.

  In the reel control process, it is configured to determine whether or not a stop command is generated on condition that the start flag is not set. That is, when the start flag is set while the reel is rotating, the stop command is invalidated. With such a configuration, when an abnormality occurs in the second clock circuit 181 while the second clock signal is still output, the abnormality can be quickly discovered. If the abnormality occurs in the middle of the game, it is impossible to stop the corresponding reel even if the stop switch is operated. This is because it is possible to notify the user of the fact. Further, when the abnormality occurs and the reels 42L, 42M, and 42R start to rotate under the condition that the start lever 71 is not operated, the stop switch 72 is used to end the game while the player feels uncomfortable. The possibility of operating ~ 74 is conceivable. However, even if the stop switch cannot be operated, the corresponding reel cannot be stopped, so that it is possible to notify the player or the game hall manager that some abnormality has occurred in the slot machine 10.

  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, the monitoring circuit 182 configured by the D flip-flop circuit is provided. However, the monitoring circuit configured by sequential circuits such as the RS flip-flop circuit and the JK flip-flop circuit and various logic circuits. May be provided.

  (B) In the above embodiment, the Q bar terminal of the monitoring circuit 182 is connected to the CPU 151, and the L level output signal output from the Q bar terminal is recognized by the CPU 151 as a start signal. Even when the CPU 151 is connected via an inverter, it is obvious that the same effects as those of the above-described embodiment can be obtained. Further, if the CPU 151 recognizes an H level output signal as a start signal, the Q terminal and the CPU 151 may be connected, or the Q bar terminal and the CPU 151 may be connected via an inverter. . The same applies to the connection between the monitoring circuit 182 and the random number generator 180.

  (C) In the above embodiment, the start detection sensor 71 a is connected to the random number generator 180 via the monitoring circuit 182. However, the start detection sensor 71 a is connected to the random number generator 180 via the monitoring circuit 182. It is good also as a structure connected. Even in such a configuration, if any abnormality occurs in the second clock circuit 181, the start signal is not input to the CPU 151 and the game is not started, so that the same effect as the above embodiment can be obtained. Is clear.

  (D) In the above embodiment, one monitoring circuit 182 is used, and a start signal is output to the CPU 151 and a latch signal is output to the random number generator 180 in accordance with a change in the output state of the second clock signal. However, it is not limited to this. A monitoring circuit that outputs a start signal to the CPU 151 according to a change in the output state of the second clock signal, and a monitoring circuit that outputs a latch signal to the random number generator 180 according to a change in the output state of the second clock signal. It may be provided separately. However, in such a configuration, there is a concern that the main control device 131 may become complicated and increase in cost due to an increase in the number of monitoring circuits.

  (E) In the above embodiment, the monitoring circuit 182 is configured to switch the output state of the start signal and the latch signal at the timing when the signal input to the CLK terminal switches from the L level to the H level. The output state of the start signal and the latch signal may be switched at the timing of switching from the H level to the L level. In such a configuration, the update timing of the count value and the latch timing of the count value in the random number generator 180 can be shifted without providing the inverter 184.

  (F) In the above embodiment, the monitoring circuit 182 constituted by the D flip-flop circuit is provided to prevent the player or the game hall from being disadvantaged when any abnormality occurs in the second clock circuit 181. The configuration is changed, but the configuration is changed.

  A watchdog timer that constantly monitors whether the second clock circuit 181 periodically outputs the second clock signal is connected to the second clock circuit. The watchdog timer is provided with a timer counter that is subtracted every predetermined time, and the timer value of the timer counter is set every time the input state of the clock signal changes. The watchdog timer outputs an H level normal signal when the timer counter is non-zero, and outputs an L level abnormality occurrence signal when the timer counter is zero. On the output side of the watchdog timer, an AND circuit that calculates the logical product of the operation signal from the start detection sensor 71a and the input signal from the watchdog timer is provided. Then, an inverted signal obtained by inverting the output signal from the AND circuit by an inverter is input to the CPU 151.

  In this case, if the second clock circuit 181 periodically outputs the second clock signal, the timer value is repeatedly set in the watchdog timer, and the timer counter does not become zero. Therefore, the output signal from the watchdog timer is always at the H level, and the output signal from the AND circuit is the operation signal from the start detection sensor 71a. When an operation signal is output, the output signal is inverted by an inverter and input to the CPU 151 as a start signal.

  On the other hand, when the output state of the second clock signal does not change due to an abnormality in the second clock circuit 181, the timer counter becomes zero in the watchdog timer, and the output signal becomes L level. For this reason, the output signal of the AND circuit is always at the L level regardless of whether the operation signal is input. Therefore, even if the start lever 71 is operated and an operation signal is output, no start signal is output from the AND circuit to the CPU 151. As a result, a situation occurs in which the reels 42L, 42M, and 42R do not start rotating despite the operation of the start lever 71, indicating that some abnormality has occurred in the slot machine 10 and the player or the game hall It is possible to notify those concerned.

  Note that the watchdog timer is used to determine whether the second clock signal is periodically output from the second clock circuit 181. Instead, the duty ratio of the second clock signal is detected. A duty ratio determination circuit that outputs an L level signal when the duty ratio is not within a predetermined normal range (for example, a range of 25 to 75%) may be provided.

  In general, the normal second clock signal is a pulse signal having a duty ratio of 50%. On the other hand, when the output state of the second clock signal does not change due to some abnormality in the second clock circuit 181, the duty ratio is 0% (in the case of constant or high impedance at the L level). ) Or 100% (if it is constant at the H level). Therefore, it is possible to determine whether the second clock signal is periodically output by determining whether the actual duty ratio is within the normal range. In this configuration, when the output state of the second clock signal is not changed, an L level signal is output from the duty ratio determination circuit, and therefore the output signal of the AND circuit depends on whether or not the operation signal is input. Always L level. Therefore, even if the start lever 71 is operated and an operation signal is output, no start signal is output from the AND circuit to the CPU 151.

  Note that the normal range of the duty ratio of the second clock signal is not limited to the above example, and may be 10 to 90%, 40 to 80%, or the like. Further, it is not necessary to set the contrast centering on 50% during normal operation, and it may be 10-60% or 40-90%.

  (G) In the above embodiment, the random number generator 180 updates the count value of the counter 180a based on the input of the second clock signal, and the count value of the counter 180a at the timing when the latch signal is input is latched 180b. However, the following configuration may be used.

  The latch circuit 180b is configured to latch after appropriately replacing the bit arrangement of the count value of the counter 180a.

  As an example of such a configuration, a configuration in which the latch circuit 180b latches the bit arrangement from the lowest order to the highest order of the count value of the counter 180a in the reverse direction can be given. In such a configuration, the value latched by the latch circuit 180b changes irregularly with respect to the input of the second clock signal, and it is possible to avoid a problem that a predetermined random number is intentionally acquired by the player. .

  Alternatively, the bit array of the values latched by the latch circuit 180b may be appropriately replaced and then output to the CPU 151 as a random number. Even in the case of such a configuration, the random number input to the CPU 151 changes irregularly with respect to the second clock signal, and it is avoided that a predetermined random number is intentionally acquired by the player. it can.

  A plurality of clock circuits for outputting clock signals having different frequencies are provided, and the count value of the counter 180a is updated based on these clock signals.

  In this case, a selection circuit that appropriately selects which clock circuit the clock signal output from is used is provided, and the clock signal selected by the selection circuit is input to the CLK terminal of the monitoring circuit 182. In such a configuration, the cycle in which the count value of the counter 180a makes a round changes depending on the selection of the clock signal by the selection circuit, so that it is possible to avoid a problem that a predetermined random number is intentionally acquired by the player.

  Instead of the counter 180a, an arithmetic unit is provided in which the random number changes every time the input state of the second clock signal changes.

  Examples of such an arithmetic unit include those that determine the current random number using random numbers up to the previous time, those that generate random numbers by the average sampling method, and those that generate random numbers by adding prime numbers. . Even in these configurations, the value latched by the latch circuit 180b changes in a complicated manner based on the change in the input state of the second clock signal, so that it is possible to prevent the player from deliberately obtaining a predetermined random number. it can.

  (H) Although the second clock circuit 183 for random numbers is provided as a clock source for the hardware random number generator 180 in addition to the first clock circuit 154 for the CPU 151 in the above embodiment, the first clock circuit 154 It may be used as a clock source. At this time, the clock signal of the first clock circuit 154 obtained by frequency modulation (frequency division, multiplication, etc.) may be used. In this case, if the clock signal input to the hardware random number generator 180 does not fluctuate due to, for example, an abnormality in a circuit unit that performs frequency modulation, there is a problem that the random number is always constant. By obtaining the same effect as the form, the abnormality can be discovered.

  (I) In the above embodiment, the second clock signal is input to the random number generator 180 and the monitoring circuit 182 without modulating the frequency of the second clock signal output from the second clock circuit 181. However, a configuration may be adopted in which frequency-modulated (frequency-divided, multiplied, etc.) signals are input. Specifically, a converter that performs frequency modulation may be connected to the second clock circuit 181, and the converter may be connected to the random number generator 180 and the monitoring circuit 182.

  (J) When the random number generator 180 in the above embodiment receives the latch signal from the monitoring circuit 182, the random number generator 180 latches the count value at that timing and outputs the latched count value to the CPU 151. Such a configuration is changed. That is, when a latch signal from the monitoring circuit 182 is input, the random number generator 180 only latches the count value at that timing, and does not output the count value to the CPU 151. Then, the CPU 151 outputs a request signal to the random number generator 180 when the lottery process is performed (step S701). When the request signal is input, the random number generator 180 latches at that time. The count value is output to the CPU 151.

  (K) In the above embodiment, an example in which the slot machine 10 is embodied has been described. However, the present invention can also be applied to a pachinko machine. In the case of a pachinko machine, the gaming machine main body is mounted on the outer frame, and a door member is provided on the front side of the gaming machine main body. The game machine body is provided with a game board in which a game area as a game ball flight area is formed and an operation port and a liquid crystal display device are installed, and the game area and liquid crystal are provided by a visual window provided on the door member. The display device is visible. Then, along with the winning of the game ball launched by the game ball launching device to the operating port, a random number is acquired and an internal lottery is performed, and the variation of the pattern on the liquid crystal display device based on the lottery result Display is performed.

  In this case, if some abnormality occurs in the clock circuit used to generate the random number and the output state of the clock signal does not change, the picture can be changed on the liquid crystal display device even though the game ball has won the operating opening. There is a situation in which the display of the change of the picture on the liquid crystal display device is started even though the display is not performed or the game ball has not won the operation opening, and the player or the manager of the game hall etc. It is possible to notify that some abnormality has occurred in the pachinko machine.

  In addition, the present invention can be applied to a gaming machine of a type in which a slot machine and a pachinko machine are fused. 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. If such a gaming machine is used in place of a slot machine, only a ball can be handled as a gaming value in a gaming field, so that it is a gaming value found in current gaming fields where both 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.
