Description

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

  For example, in a 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 a display window. Then, when the player inserts a medal, an effective line is set, and then the player operates the start lever to play a big bonus (hereinafter referred to as “BB”) role or small role in the slot machine. In addition, a lottery such as a re-game is performed and each reel starts to rotate. After each reel starts to rotate, each reel is sequentially stopped to finish one game. When all reels stop rotating, the winning combination will be awarded if the combination of the winning combination on the active line is stopped, and the player will receive a medal reward or a game state transition privilege. Is done. Here, in a slot machine, it is common to acquire a random number by operating a start lever, and to perform a lottery drawing using the random number (see, for example, Patent Document 1).

  Hereinafter, an embodiment in the case of application to a spinning cylinder type gaming machine, which is a kind of gaming machine, specifically, a slot machine will be described in detail with reference to the drawings. 1 is a front view of the slot machine 10, FIG. 2 is a perspective view of the slot machine 10 with the front door 12 closed, FIG. 3 is a perspective view of the slot machine 10 with the front door 12 opened, and FIG. 5 is a rear view of the door 12, and FIG.

  As shown in FIGS. 1 to 5, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The casing 11 as a whole is formed in a box shape with the front face open, and is attached by, for example, driving nails against a so-called island facility when installed in the game hall.

  A front door 12 is attached to the front side of the housing 11 so as to be openable and closable. That is, the housing 11 is provided with a pair of upper and lower support shafts 13a and 13b on the left side when viewed from the front, and the front door 12 has a bearing portion 14a at a position corresponding to each support shaft 13a and 13b. , 14b are provided. When the support shafts 13a and 13b are inserted into the bearing portions 14a and 14b, the front door 12 rotates about an opening / closing axis extending in the vertical direction connecting the support shafts 13a and 13b to the housing 11. The front door 12 can be opened and closed by rotating the front door 12 so as to be movable. Further, the front door 12 is brought into a locked state that cannot be opened by a locking device 20 provided on the back surface thereof. A key cylinder 21 that is integrated with the locking device 20 is provided on the upper right side of the front door 12, and is configured such that the locked state is released by a predetermined key operation on the key cylinder 21.

  A game panel 25 for notifying the player of the game state is provided above the center of the front door 12. The game panel 25 is formed with three vertically long display windows 26L, 26M, and 26R, and the inside of the slot machine 10 is visible through the display windows 26L, 26M, and 26R. The display windows 26L, 26M, and 26R may be combined into a single display window.

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

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

  Each of the reels 32L, 32M, and 32R is connected to a stepping motor of 1-2 phase excitation, and each of the reels 32L, 32M, and 32R is individually rotated, that is, independently driven by the driving of each stepping motor. It is the structure to obtain. The stepping motor is set to rotate once by giving a drive signal (hereinafter also referred to as excitation pulse or excitation data) of 504 pulses, for example, and the rotation position of the stepping motor, that is, the reel The rotational position is controlled. In addition, the reel unit 31 is provided with a reel index sensor for detecting that the reel has made one rotation in association with each of the reels 32L, 32M, and 32R. The reels 32L, 32M, and 32R each include a reel. A sensor cut van capable of passing through the element portion of the index sensor is attached. Each time the reel makes one revolution, the reel index sensor detects the passage of the sensor cut bang, and a detection signal is output to the main controller 101 described later each time the reel is detected. Therefore, main controller 101 determines the angular position of each reel 32L, 32M, 32R for each rotation based on the detection signal of the reel index sensor and the number of excitation pulses output until the detection signal is input. It can be confirmed and corrected.

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

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

  FIG. 6 shows a symbol arrangement of the left reel 32L, the middle reel 32M, and the right reel 32R. As shown in the figure, 21 symbols are arranged in a line on each of the reels 32L, 32M, and 32R. Further, numbers from 0 to 20 are assigned to the reels 32L, 32M, and 32R. These numbers are symbols that are visible to the main controller 101 from the display windows 26L, 26M, and 26R. Is a number for recognizing and not actually attached to the reels 32L, 32M, 32R. However, in the following description, the number is used for explanation.

  As symbols, “star” symbol (for example, 20th of left reel 32L), “cherry” symbol (for example, 19th of left reel 32L), “youth” symbol (for example, 18th of left reel 32L), “ “Bell” symbol (for example, 17th of left reel 32L), “Replay” symbol (for example, 16th of left reel 32L), “White 7” symbol (for example, 15th of left reel 32L), “Watermelon” symbol ( For example, there are eight types of 14th of the left reel 32L) and “red 7” symbol (for example, the third of the left reel 32L). As shown in FIG. 6, the number and arrangement order of various symbols on the reels 32L, 32M, and 32R are completely different.

  Each of the display windows 26L, 26M, and 26R is formed so that there are three symbols from which the entire symbol can be visually recognized out of the twenty-one symbols attached to the corresponding reel. Therefore, when all the reels 32L, 32M, and 32R are stopped, 3 × 3 = 9 symbols are visible through the display windows 26L, 26M, and 26R.

  In this slot machine 10, a total of five combination lines are set, connecting three positions where these nine symbols become visible, three in parallel in the horizontal direction and two in the diagonal direction. ing. More specifically, as shown in FIG. 7, as a combination line in the horizontal direction, the upper line L1 connecting the upper symbols of each reel 32L, 32M, 32R and the middle symbol of each reel 32L, 32M, 32R are connected. A line L2 and a lower line L3 connecting the lower symbols of the reels 32L, 32M, 32R are set. Further, as a combination line in the oblique direction, a lower right line L4 connecting the upper symbol of the left reel 32L, the middle symbol of the middle reel 32M, the lower symbol of the right reel 32R, the lower symbol of the left reel 32L, and the middle symbol of the middle reel 32M. A right rising line L5 connecting the upper symbol of the symbol and the right reel 32R is set. And, when the combination line is activated, that is, when the symbols are stopped in a predetermined combination on the effective line, a privilege that a predetermined number of medals as game media are paid out is given or the gaming state is shifted as winning establishment. Benefits are granted.

  FIG. 8 shows a combination of symbols for winning and a privilege to be given when winning.

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

  As a state transition prize in which only the game state transition is performed, there is a BB prize. When the “red 7” symbols of the reels 32L, 32M, and 32R stop alongside the active line, the gaming state shifts to a big bonus state (hereinafter referred to as “BB state”) as a BB winning.

  As a prize to which a privilege other than medal payout or game state transition is given, there is a re-game prize. When the “replay” symbols of the reels 42L, 42M, and 42R stop side by side on the active line, the medals are not paid out or the game state is not transferred as a re-game winning, but the next game is not inserted without inserting medals. A re-game privilege that allows a game to be played is given.

  Hereinafter, a combination of symbols corresponding to each prize is also referred to as a combination of winning symbols. For example, the combination of replay symbols is a combination of symbols for a replay prize, that is, a combination of “replay” symbol, “replay” symbol, and “replay” symbol. The symbols of the reels 32L, 32M, and 32R corresponding to the winnings are also referred to as winning symbols. For example, the single-seat symbol is a “red 7” symbol on the left reel 32L, a “youth” symbol on the middle reel 32M, and a “white 7” symbol on the right reel 32R.

  On the lower left side of the game panel 25, a start lever 41 that is operated to start rotation of the reels 32L, 32M, and 32R is provided. The start lever 41 constitutes start operation means or start operation means operated to start rotation of the reels 32L, 32M, and 32R, that is, to start variable display of symbols. The start lever 41 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 41 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 41 is operated while a predetermined number of medals are inserted, the reels 32L, 32M, and 32R start to rotate.

  On the right side of the start lever 41, button-like stop switches 42 to 44 that are operated to individually stop the rotating reels 32L, 32M, and 32R are provided. Each of the stop switches 42 to 44 is disposed immediately below the display windows 26L, 26M, and 26R corresponding to the reels 32L, 32M, and 32R to be stopped. That is, when the left stop switch 42 is operated, the rotation of the left reel 32L is stopped. When the middle stop switch 43 is operated, the rotation of the middle reel 32M is stopped and the right stop switch 44 is operated. In this case, the rotation of the right reel 32R is stopped. The stop switches 42 to 44 constitute stop operation means operated to stop the variable display of symbols based on the rotation of the reels 32L, 32M, 32R. The stop switches 42 to 44 are configured to be in a stopable state when a predetermined time has elapsed after the left reel 32L starts to rotate. A lamp (not shown) is provided inside the stop switches 42 to 44. The lamp is turned on when the stop operation is possible, and the lamp is turned off when the stop operation is impossible such as when the reel is stopped. It has become so.

  On the lower right side of the display windows 26L, 26M, 26R, a medal insertion slot 45 for inserting medals is provided. The medal slot 45 constitutes an input means for inputting game media. If attention is paid to the point that the medal insertion slot 45 is directly inserted by the player, it can be said that it constitutes a direct input means for directly inputting the game medium.

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

  The hopper device 51 includes a storage tank 52 that stores medals and a payout device 53 that pays out medals to a player. The payout device 53 rotates a medal payout rotating plate (not shown) to discharge the medal to the opening 48 a provided in the discharge passage 48 and to pay out the medal to the medal tray 50 through the discharge passage 48. It has become. In addition, a reserve tank 54 is provided on the right side of the hopper device 51 to avoid storing a predetermined amount or more of medals in the storage tank 52. Inside the storage tank 52 of the hopper device 51, a guide plate 52a for discharging medals from the storage tank 52 to the reserve tank 54 is provided. Therefore, when medals are stored more than the height at which the guide plate 52 a is provided, the medals are stored in the reserve tank 54.

  A button-like return switch 55 is provided below the medal slot 45. When the return switch 55 is operated in a situation where a medal inserted into the medal insertion slot 45 is jammed in the selector 46, the selector 46 is mechanically operated so that the medal jammed in the selector 46 becomes a medal. It is returned from the discharge port 49.

  On the lower left side of the display windows 26L, 26M, 26R, there is provided a first credit insertion switch 56 for inserting three credited virtual medals as game media at a time. Further, a second credit insertion switch 57 and a third credit insertion switch 58 are provided on the left side of the first credit insertion switch 56. The second credit insertion switch 57 is for inserting two virtual medals at a time, and the third credit insertion switch 58 is for inserting one virtual medal. Each of the credit insertion switches 56 to 58 constitutes input means for inputting a game medium together with the medal insertion slot 45. It should be noted that the medal insertion slot 45 is accompanied by an operation of directly inserting a medal by the player, whereas each of the credit insertion switches 56 to 58 is only accompanied by an operation of inserting a virtual medal based on the storage memory. In other words, it can be said to constitute indirect input means for indirectly inputting game media. A lamp (not shown) is provided inside each of the credit insertion switches 56 to 58, and the lamp is turned on when the insertion operation is possible, and the lamp is turned off when the insertion operation is impossible. .

  A settlement switch 59 is provided on the left side of the start lever 41. In other words, 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 payout medals at the time of winning as virtual medals. When the settlement switch 59 is operated under the stored and stored condition, the virtual medal is paid out from the medal discharge port 49 as an actual medal. 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 59 constitutes a checkout operation means for actually paying out the stored game media.

  Below the display windows 26L, 26M, and 26R of the game panel 25, a credit display unit 60 that displays the number of credited virtual medals, and a remaining payout number that displays the number of remaining medals to be paid out before the BB state ends. A display unit 61 and a payout number display unit 62 for displaying the number of medals paid out at the time of winning are provided. Although these display parts 60-62 are comprised by the 7 segment display, it is naturally possible to substitute by a liquid crystal display etc. FIG.

  Here, the relationship between the number of medals bet and the activated combination line will be described with reference to FIG. A bet is made when a medal is inserted from the medal slot 45 at the start of the game.

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

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

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

  Incidentally, when any one of the first to third credit insertion switches 56 to 58 is operated and the virtual medal to be inserted is not stored and stored, for example, the first display when the display of the credit display unit 60 is “2”. For example, when the credit insertion switch 56 is operated, all the numerical values in the credit display unit 60 are subtracted to 0, and a bet is made for the amount of virtual medals that can be inserted.

  The upper part of the front door 12 has an upper lamp 63 that lights up or flashes as the game progresses, and a pair of left and right sounds that produce various sound effects as the game progresses and inform the player of the gaming state. Speaker 64 and an auxiliary display unit 65 for giving various information to the player. The auxiliary display unit 65 is for executing various display effects as the game progresses, and it can be considered that the game by each reel 32L, 32M, 32R is caused by the main display unit. This is referred to as an auxiliary display unit 65. A display control device 81 for driving the upper lamp 63, the speaker 64, and the auxiliary display unit 65 is provided on the back surface of the auxiliary display unit 65.

  A power supply box 70 is provided on the left side of the hopper device 51 inside the housing 11. The power supply box 70 accommodates a power supply device 91 therein, and includes a power switch 71, a reset switch 72, a setting key insertion hole 73, and the like. The power switch 71 is a start switch for supplying power to each unit including the main controller 101. The reset switch 72 is a switch for resetting an error state of the slot machine 10. Further, the setting key insertion hole 73 is used by a hole manager or the like to adjust the appearance of medals. 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 73 and turning it ON. The reset switch 72 is operated not only when the error state is reset but also when the winning probability of the slot machine 10 is changed.

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

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

  The main control device 101 is equipped with a microcomputer centering on a CPU 102 which is arithmetic processing means. In addition to the power supply device 91, the CPU 102 includes a first clock circuit 103 that outputs a rectangular wave (first clock signal) having a predetermined frequency of 8.000 MHz, and an input / output port 104 (specifically, a connector and a driver IC). , An input / output port constituted by a chip select IC or the like), a random number generator 150 for generating random numbers, and the like are connected via an internal bus. The main control device 101 functions as a main board built in the slot machine 10.

  On the input side of the main controller 101, a reel unit 31 (more specifically, a reel index sensor that individually detects that each of the reels 32L, 32M, and 32R has made one rotation) and a start detection sensor that detects an operation of the start lever 41 are provided. 41a, stop detection sensors 42a to 44a that individually detect the operation of each of the stop switches 42 to 44, a inserted medal detection sensor 45a that detects a medal inserted from the medal slot 45, and a medal paid out from the hopper device 51. Payment detection sensor 51a, credit insertion detection sensors 56a-58a that individually detect the operation of each credit insertion switch 56-58, settlement detection sensor 59a that detects the operation of the settlement switch 59, and reset detection that detects the operation of the reset switch 72 Sensor 72a, setting key insertion hole 7 Various sensors such as a setting key detection sensor 73 a for detecting that the setting key is inserted and turned ON are connected, and signals from these various sensors are output to the CPU 102 via the input / output port 104. It has become.

  The inserted medal detection sensor 45a is actually composed of a plurality of sensors. That is, the storage passage 47 from the medal slot 45 to the hopper device 51 is formed so that medals can pass in one row. The storage passage 47 is provided with the first sensor, and the second sensor and the third sensor are close to each other on the downstream side more than the width of the medal (a state where the same medal is detected at least at the same time occurs). In close proximity). The inserted medal detection sensor 45a includes these first to third sensors. The main control device 101 monitors the time from the first sensor to the second sensor, and if the elapsed time exceeds a predetermined time, the main control device 101 regards that there is a medal clogging or fraud and sets an error state. When an error state occurs, an error state notification is performed and the operation by the player is invalidated until the error state is canceled. The main controller 101 also monitors the order in which the second sensor and the third sensor are turned on and off. Specifically, both the second and third sensors are off, only the second sensor is on, both the second and third sensors are on, only the third sensor is on, and both the second and third sensors are off. It is determined that the medal has been normally taken in only when the time for shifting to each on / off switching is within a predetermined time. Otherwise, an error state is set. The reason for this is to prevent injustice that the medal is reciprocated in the vicinity of the inserted medal detection sensor 45a and misidentified as a medal inserted in addition to the clogging of the medal in the storage passage 47.

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

  The power failure monitoring circuit 91b monitors the power-off state and generates a power failure signal not only at the time of power failure but also when the power switch 71 powers off. For this reason, the power failure monitoring circuit 91b monitors the stabilized drive voltage of 12 VDC in this example output from the power supply unit 91a, and determines that the power supply has been shut off when this drive voltage drops below, for example, 10 volts. Power outage signal is output. The power failure signal is supplied to each of the CPU 102 and the input / output port 104. The CPU 102 recognizes this power failure signal and executes a power failure process described later. The power failure signal is also supplied to the display control device 81.

  The power supply unit 91a is configured to output a stabilized voltage of 5 volts that is used as a drive voltage in a control system such as the main controller 101 even when the output voltage drops below 10 volts. As a time for outputting the stabilization voltage, a time sufficient for executing the power failure process by the main controller 101 is secured.

  On the output side of the main controller 101, a reel unit 31 (more specifically, a stepping motor for rotating the reels 32L, 32M, and 32R), a medal path switching solenoid 46a provided in the selector 46, a hopper device 51, a credit A display unit 60, a remaining payout number display unit 61, a payout number display unit 62, a display control device 81, an external concentration terminal board 121 that can transmit information to a hall management device (not shown), and the like are connected via an input / output port 104. Yes. Although not shown, a lamp provided in the stop switches 42 to 44 and a lamp provided in the credit insertion switches 56 to 58 are also input / output on the output side of the main controller 101. It is connected via the port 104.

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

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

  As shown in FIG. 10, in the RAM 106, a winning flag storage area 106a for storing the lottery result of the winning combination, and a sliding table for storing a sliding table used when stop control of each of the reels 32L, 32M, 32R is performed. In addition to the storage area 106b, the state information storage area 106c for storing the gaming state such as the BB state, the random number storage area 110 for storing the random number generated by the random number generator 150, the counter having a function as various counters Various areas such as area 111 and sensor information storage area 112 for storing the signal input status from the various sensors described above are secured. The counter area 111 includes a first counter 111a for determining the acquisition timing of a random number, an update counter 111c used in interrupt waiting processing described later, a credit counter (not shown) for storing the number of credits, and the like. Yes. The sensor information storage area 112 includes a reel index detection area, a start detection area, a left stop detection area, a middle stop detection area, a right stop detection area, an inserted medal detection area, a payout detection area, and a first credit. An insertion detection area, a second credit insertion detection area, a third credit insertion detection area, a settlement detection area, a reset detection area, a setting key detection area, and the like. Each of these detection areas can store a history of presence / absence of signal input from a corresponding detection sensor, and includes three storage areas of a first area 112a, a second area 112b, and a third area 112c. It is composed of Each detection area has a 1-byte configuration, and the lower 3 bits are associated with each storage area. More specifically, they are associated with the first area 112a, the second area 112b, and the third area 112c in order from the lower bit.

  The RAM 106 is configured to hold (backup) data by being supplied with a backup voltage from the power supply device 91 even after the power to the slot machine 10 is cut off. The RAM 106 holds data in the RAM 106. 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 shutdown by operating the power switch 71; the same applies hereinafter). Yes, when the power failure is resolved (including power-on by operating the power switch 71; 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. 12), and restoration of each value written to the backup area is executed in the main process (see FIG. 14) when the power is turned on.

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

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

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

  The random number generator 150 is hardware having a counter 150a and a latch circuit 150b. The counter 150a is a 16-bit free-run counter 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 151 is connected to the counter 150a, and when the second clock signal from the second clock circuit 151 is input, the count value of the counter 150a is updated. The latch circuit 150b is configured by combining a plurality of D flip-flop circuits, and can latch (hold) the count value of the counter 150a. The CPU 102 is connected to the latch circuit 150b. When a latch signal is input from the CPU 102, the count value of the counter 150a at that timing is latched in the latch circuit 150b. The latched count value is output as a random number to an input port built in the CPU 102.

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

  The start detection sensor 41a outputs an operation signal when the start lever 41 is operated. More specifically, the start detection sensor 41a outputs an operation signal when the start lever 41 moves from the initial position, and stops outputting the operation signal when the start lever 41 returns to the initial position. The waveform shaping circuit 153 is configured by a Schmitt trigger circuit. A threshold is set in the waveform shaping circuit 153, and the waveform shaping circuit 153 sends a detection signal to the monitoring circuit 152 when the operation signal output from the start detection sensor 41a 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. In other words, the waveform shaping circuit 153 is a circuit for shaping a round (rise delay and fall delay) of the operation signal output from the start detection sensor 41a. The waveform shaping circuit 153 may be connected between the input / output port 104 and the monitoring circuit 152, and the waveform shaping circuit 153 may be provided on the main controller 101.

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

  In addition to the Q bar terminal of the monitoring circuit 152, the latch circuit 150 b of the random number generator 150 and the first clock circuit 103 that outputs the first clock signal are connected to the input side of the CPU 102. Further, a latch circuit 150 b of the random number generator 150 is connected to the output side of the CPU 102. The first clock circuit 103 outputs a rectangular wave having a predetermined frequency of 8.000 MHz and is configured not to be synchronized with the second clock circuit 151. The CPU 102 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 a latch signal is output to the random number generator 150 based on the input of the start signal. The count value output from the random number generator 150 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 102 is connected to the Q bar terminal of the monitoring circuit 152, 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, each control process executed by the CPU 102 of the main control apparatus 101 will be described. The CPU 102 performs various processes based on the input of the first clock signal from the first clock circuit 103. The processing of the CPU 102 is roughly divided into a main processing that is started when the power is turned on, a timer interrupt processing that is started periodically (in a cycle of 1.49 msec in the present embodiment), and a power failure signal to the NMI terminal. NMI interrupt processing that is activated in response to the input of. In the following, for convenience of explanation, timer interrupt processing will be described first, and then main processing will be described.

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

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

  Here, an outline of the power failure process will be described.

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

  In the power failure process, it is first determined whether or not the 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. If the command transmission has been completed, the value of the stack pointer of the CPU 102 is stored in the backup area of the RAM 106. Thereafter, the output state of the output port in the input / output port 104 is cleared, and all actuators (not shown) are turned off. Then, a RAM determination value for determining whether or not the data in the RAM 106 is normal when the power failure is eliminated is stored in the backup area. The RAM determination value is specifically a two's complement of the checksum at the work area address of the RAM 106. By storing the RAM determination value in the backup area, the checksum of the RAM 106 becomes zero. By setting the checksum of the RAM 106 to 0, subsequent RAM access is prohibited. After performing the above processing, an infinite loop is entered in preparation for the case where the power supply is completely shut down and the processing cannot be executed. In consideration of, for example, the case where the power failure flag is set erroneously due to noise or the like, it is confirmed whether or not a power failure signal is output until the infinite loop is entered. If the power failure signal is not output, the power failure state is recovered, so that writing to the RAM 106 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, 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 main processing is performed.

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

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

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

  Returning to the description of the timer interrupt process, in step S108, a timer calculation process for subtracting the value of each counter or timer is performed. In step S109, the value of the update counter 111c is updated by one. In step S110, a process of outputting the bet number of medals and the result of counting the number of payouts to the external concentration terminal board 121 is performed. In step S111, command output processing for transmitting various commands such as a lottery result command to be described later to the display control device 81 is performed. In step S112, a segment data setting process for setting segment data displayed on the credit display unit 60, the remaining payout number display unit 61, and the payout number display unit 62 is performed. In step S113, segment data set processing in the segment data setting processing is supplied to the display units 60 to 62, and segment data display processing for displaying corresponding numbers, symbols, and the like is performed. In step S114, port output processing for outputting data corresponding to the I / O device from the input / output port 104 is performed. In step S115, the value of each register saved in the backup area in the previous step S101 is returned to the corresponding register in the CPU 102, respectively. In step S116, a counter update process is performed. Although details will be described later, in the counter update process, a process of adding 1 to the value of the first counter 111a is performed based on the progress of the game. In step S117, a delay counter process for subtracting the value of the first counter 111a is performed. Thereafter, in step S118, the next timer interrupt is permitted, and this series of timer interrupt processing ends.

  FIG. 14 is a flowchart showing a main process in the main controller 101 that is executed after the power is turned on. The main processing is executed when power is turned on by recovery from a power failure or by turning on the power switch 71.

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

  In the operation determination process, first, in step S251, it is determined whether or not the current determination target is the reset switch 72. In step S252, the current determination target is one of the first to third credit insertion switches 56 to 58. It is determined whether or not there is. When the current determination target is any one of the reset switch 72 and the first to third credit insertion switches 56 to 58, the entire area reference process shown in steps S253 to S256 is performed. On the other hand, if the current determination target is other than the above switches, specifically, if it is any of the start lever 41, the stop switches 42 to 44, the checkout switch 59, and the setting key, steps S257 to S260 are performed. 1 area reference process shown in FIG.

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

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

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

  In step S204, 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 winning probability is used to execute the internal processing. It is a process to do.

  In step S301, the next timer interrupt is permitted. Thereafter, the current set value is read in step S302, and the current set value is displayed on the credit display unit 60 in step S303. However, in the process immediately after the setting key is inserted and turned on, the data in the RAM 106 is cleared by the previous forced RAM clearing process, so the setting value displayed on the credit display unit 60 is “1”. is there.

  In step S304, an interrupt waiting process is performed.

  In the interrupt waiting process, as shown in the flowchart of FIG. 17, a register saving process is performed in step S351. In step S352, the next timer interrupt is permitted and the current value of the update counter 111c is acquired. In step S353 to step S357, counter update processing is performed. In the counter update process, first, the next timer interruption is prohibited in step S353, and then it is determined in step S354 whether or not a game flag described later is set. If the game flag is set, the value of the first counter 111a is updated by 1 in step S355. Here, the first counter 111a is a 4-bit storage area formed in the RAM 106, and can generate a count value of 0 to 16. After updating the value of the first counter 111a or when it is determined in step S354 that the game flag is not set, the process proceeds to step S356, and the next timer interruption is permitted. In step S357, it is determined whether or not the value of the update counter 111c has changed. Specifically, it is determined whether or not the value acquired in step S352 matches the value of the update counter 111c. As described above, the value of the update counter 111c is updated in step S109 of the timer interrupt process. For this reason, when the value of the update counter 111c has not changed, it means that the timer interrupt process has not been performed after the process of step S352. In such a case, the process returns to step S353 to perform counter update processing. On the other hand, if the value of the update counter 111c has changed, it means that timer interrupt processing has been performed, so that register return processing is performed in step S358, and this processing ends.

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

  If the start lever 41 is operated in step S305, an interrupt waiting process is performed in step S309, and then it is determined in step S310 whether the setting key is continuously turned on. If the ON operation of the setting key is continued, the process returns to step S309, and if the ON operation is ended, the next timer interruption is prohibited in step S311. Thereafter, in step S312, the set value is saved, and in step S313, data other than the set value and the value of the first counter 111a is cleared from the data stored in the RAM 106, and this process is terminated.

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

  On the other hand, if the setting key is not turned on in step S202, power recovery processing shown in step S206 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 106 is normal.

  Therefore, in step S206, it is determined whether or not the set value is normal. Specifically, when the set value is any 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 S207 whether or not a power failure flag is set. If the power failure flag is set, it is further confirmed in step S208 whether or not the RAM determination value is normal. Specifically, the checksum value of the RAM 106 is checked to check whether the value is normal, that is, whether the checksum value including the RAM determination value is 0 or not. If the checksum value including the RAM determination value is 0, it is determined that the data in the RAM 106 is normal.

  If it is determined in step S208 that the RAM determination value is normal, the process proceeds to step S209, where the stack pointer value stored in the backup area is written to the stack pointer of the CPU 102, and the stack state before the power is shut off. Return to the state. Next, in step S <b> 210, a power recovery command that tells execution of power recovery processing is transmitted to the display control device 81. Thereafter, in step S211, the game state is stopped and automatic settlement setting storage processing is performed. In step S212, various sensors such as the start detection sensor 41a are initialized. After the above processing is completed, the power failure flag is reset in step S213, and the processing returns to the address before turning off the power. Specifically, the process returns to the timer interrupt process described above, and the watchdog timer clear process (step S104) is executed.

  On the other hand, if any of step S206 to step S208 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 106 has been destroyed. In such a case, the operation prohibiting process shown in steps S214 to S216 is performed. As the operation prohibition process, first, the next timer interrupt process is prohibited in step S214, and in step S215, all output ports in the input / output port 104 are cleared, so that all actuators connected to the input / output port 104 are removed. Control to off state. Thereafter, in step S216, an error notification process for notifying the occurrence of an error to the hall manager or the like using the upper lamp 63 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 S401, the next timer interrupt is permitted. In step S402, a pre-start process for enabling a game is performed. In the pre-start process, the process waits until the display control device 81 and the like finish initialization. When the initialization of the display control device 81 and the like is completed, the game management process shown in steps S403 to S408 is performed.

  As the game management process, in step S403, data such as various game information stored in the RAM 106 (for example, a random value used in the previous game) is cleared. Thereafter, in step S404, start waiting processing is performed.

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

  In step S501, 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 is performed in step S502. The automatic insertion process is a process for automatically inserting the same number of virtual medals as the previous bet number. In the automatic insertion process, a virtual medal is inserted without reducing the number of virtual medals displayed on the credit display unit 60. 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. When a re-game winning is established in the previous game, first, the same value as the number of bets is added and displayed on the credit display unit 60, and the virtual medal is inserted after reducing the added display number in the automatic insertion process. It is good also as a structure which performs. If it is determined in step S501 that a re-game winning is not established, a medal acceptance permission process for permitting betting of medals is performed in step S503. In the medal acceptance permission process, the medal passage switching solenoid 46a is switched to the excited state, so that a medal can be inserted. Thereafter, the pre-start preparation process shown in steps S504 to S518 is repeated until a start command for starting the game is generated.

  As a pre-start preparation process, first, in step S504, an abnormality confirmation process is performed to confirm whether an abnormality has occurred in the sensor reading result in the sensor monitoring process step S107 of the timer interruption process. In the abnormality confirmation process, when it is determined that an abnormality has occurred, an abnormality occurrence process is performed to place the slot machine 10 in an error state and notify the occurrence of the error. Such an error state is maintained until the reset switch 72 is operated. If the reading result of the sensor is normal, the process proceeds to step S505, and interrupt waiting processing is performed. In step S506, it is determined whether or not any of the clearing switch 59 and each of the credit insertion switches 56 to 58 has been operated.

  Specifically, with respect to the clearing switch 59, one area reference processing for operation determination processing is performed, and for each credit insertion switch 56 to 58, all area reference processing for operation determination processing is performed. That is, referring to the first area 112a of the settlement detection area, when “1” is stored, it is determined that the settlement switch 59 has been operated, and when “0” is stored, the settlement switch 59 is determined. Is determined not to be operated. When the clearing switch 59 is not operated, all areas 112a to 112c of the first credit insertion detection area are referred to. When “011” is stored, the first credit insertion switch 56 is operated. If “011” is not stored, it is determined that the first credit insertion switch 56 is not operated. When the first credit insertion switch 56 is not operated, all areas 112a to 112c of the second credit insertion detection area are referred to. When “011” is stored, the second credit insertion switch 57 is If it is determined that the second credit insertion switch 57 has not been operated, it is determined that the second credit insertion switch 57 has not been operated. When the second credit insertion switch 57 is not operated, all areas 112a to 112c of the third credit insertion detection area are referred to. When “011” is stored, the third credit insertion switch 58 is When it is determined that the third credit insertion switch 58 has not been operated, it is determined that the third credit insertion switch 58 has not been operated.

  If any of the switches 56 to 59 is operated, or if automatic insertion processing is performed in step S502, the process proceeds to step S507, and the medal payout number displayed on the payout number display unit 62 is cleared. . After that, or when neither the clearing switch 59 nor the credit insertion switches 56 to 58 are operated, a medal return process is performed in step S508. In the medal return process, if it is determined in step S506 that the settlement switch 59 has been operated, a process of paying out the same number of medals as the credited virtual medal is performed.

  In step S509, whether or not a medal can be bet is determined based on the state of the medal path switching solenoid 46a, that is, whether it is in an excited state or a non-excited state. If the bet is possible, the process proceeds to step S511 after the credit insertion process is performed in step S510. In the credit insertion process, when it is determined in step S506 that any one of the credit insertion switches 56 to 58 is operated, the virtual medal number displayed on the credit display unit 60 is displayed by subtraction or an effective line is set. Process related to the insertion of virtual medals such as If the bet is not possible, the process proceeds to step S511 without performing the credit insertion process. By the way, as a state where betting is impossible, a representative example is a case where a re-game winning is established in the previous game and an automatic insertion process is performed in step S502. In step S511, an input determination process is performed. In the insertion determination process, it is determined whether or not a medal has been inserted based on a detection signal from the inserted medal detection sensor 45a. If a medal has been inserted, processing such as setting an effective line is performed.

  In step S512, it is determined whether or not a bet is made. If the bet is not made, a setting display process is performed in step S513. In the setting display process, it is determined whether or not the setting key is inserted into the setting key insertion hole 73 and is turned on. If the setting key is turned on, the current setting value is displayed in the credit display unit 60. Process to be displayed. In step S514, it is determined whether the demonstration effect has been started. The slot machine 10 is configured to perform a demonstration effect on the auxiliary display unit 65 or the like when a predetermined time (for example, 1 minute) has elapsed since the game information in the RAM 106 was cleared in step S403. Therefore, in step S514, it is determined whether or not the predetermined time has elapsed. If the predetermined time has elapsed, a demonstration start command for starting a demonstration effect has already been transmitted to the display control device 81. It is determined whether or not there is. If the predetermined time has not elapsed, or if the demonstration start command has not been transmitted, after performing the effect waiting process in step S515, the process returns to step S504. In the effect waiting process, a counter for measuring an elapsed time after the game information in the RAM 106 is cleared is updated, and if a predetermined time has elapsed, a process of setting a demonstration start command is performed. However, in the effect waiting process, only the demonstration start command is set in the ring buffer, and the command is not transmitted to the display control device 81. The command transmission to the display control device 81 is performed in the command output process S111 of the timer interrupt process described above. If it is determined in step S514 that the demonstration start command has been transmitted, the process directly returns to step S504 without performing the effect waiting process.

  If it is determined in step S512 that the bet has been placed, it is determined in step S516 whether or not the bet number has reached the specified number (3 in the present embodiment), and the bet number has reached the specified number. If not, the process returns to step S504. If the bet number has reached the specified number, an interrupt waiting process is performed in step S517, and whether or not the start lever 41 has been operated in step S518, that is, “1” is set in the first area 112a of the start detection area. ”Is set. If the start lever 41 is not operated, the process returns to step S504.

  On the other hand, when the start lever 41 is operated, the game can be started when the start lever 41 is operated in a situation where a prescribed number of medals are betted. Means that a command has occurred. In such a case, a game flag indicating that the game has been started is set in step S519, and a command flag is set in step S520. Here, the command flag is a flag that is set when a start command or a stop command to be described later is generated, and is a flag that is cleared in the sensor monitoring process S107 of the timer interrupt process described above. More specifically, in the sensor monitoring process, when a command flag is set in a situation where a start signal is input, a command release waiting flag is set. Then, when the input of the start signal is completed, it is determined whether or not a command release waiting flag is set. If the command release wait flag is not set, the command flag is based on the generation of a stop command, which will be described later. Therefore, if the command release wait flag is set without clearing the command flag, Clear flags and command flags. If the command flag is set in step S520, a medal acceptance prohibition process is performed in step S521. In the medal acceptance prohibition process, the medal passage switching solenoid 46a is switched to a non-excited state to make it impossible to place a medal (bet). Thereafter, delay processing is performed in step S522, and this processing is terminated.

  In the delay process, as shown in the flowchart of FIG. 20, a delay flag is set in step S531. Here, the delay flag is a flag for subtracting the value of the first counter 111a. More specifically, in the delay counter process S117 of the timer interrupt process, as shown in the flowchart of FIG. 21, it is determined whether or not the delay flag is set in step S551. If the delay flag is not set, the process is terminated. If the delay flag is set, the value of the first counter 111a is decremented by 1 in step S552, and the process is terminated. To do. As described above, in the interrupt waiting process of the normal process, an update process for adding 1 to the value of the first counter 111a is performed. In addition, in a counter update process of a timer interrupt process to be described later, an update process for adding 1 to the value of the first counter 111a is performed based on the progress of the game. Therefore, it can be said that the delay flag is a flag for changing the update mode of the first counter 111a.

  Returning to the explanation of the delay process, after setting the delay flag, in step S532, it is determined whether or not the value of the first counter 111a has become zero. Here, since the value of the first counter 111a is decremented by 1 in the timer interrupt process, and the timer interrupt process is performed every 1.49 msec, step S532 is a time corresponding to the value of the first counter 111a (that is, the first counter). It can be said that this is a process of waiting until a value obtained by multiplying the value of 111a by 1.49 msec). When the value of the first counter 111a becomes 0, the process proceeds to step S533, and a latch signal is output to the random number generator 150. More specifically, in step S533, only the flag for outputting the latch signal is set, and the actual output of the latch signal is performed in the timer interrupt process. The latch signal is continuously output for one interrupt (that is, 1.49 msec) of the timer interrupt process. Thereafter, in step S534, the delay flag is cleared, and this process ends.

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

  The signal output from the second clock circuit 151 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 150, the count value of the counter 150a is updated to n. n is any value from 0 to 65535. Further, since the second clock circuit 151 is connected to the CLK terminal of the monitoring circuit 152 via the inverter 154, in the monitoring circuit 152, 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 151 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 152 switches the signal input to the CLK terminal from the L level to the H level, and switches the inverted clock signal to the input present state. At this time, in the random number generator 150, the count value of the counter 150a is not updated, and the count value remains n.

  When the inverted clock signal is switched to the input presence state, the monitoring circuit 152 outputs a signal corresponding to the input state of the operation signal input to the D terminal at that time from the Q bar terminal. Since the operation signal (H level detection signal) is not input at timing t2, the start signal is not output from the Q bar terminal. Since the start signal is output from the Q bar terminal (negative logic output terminal), 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 present state at the timing t3, the random number generator 150 updates the count value of the counter 150a to n + 1. As described above, the random number generator 150 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 41 is operated at the timing t4, the signal input to the D terminal of the monitoring circuit 152 rises from the L level to the H level, and the operation signal is switched to the input presence state. However, since the inverted clock signal is not input at the timing t4, the start signal remains 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 152, the output signal from the Q bar terminal is changed from the H level to the L level. Fall to the level. As a result, at the timing t5, the start signal is switched from the no output state to the output present state. At this time, the latch signal output from the CPU 102 remains in the no-output state. That is, no latch signal is output at timing t5 when the start signal is output.

  At the timing t6, the inverted clock signal switches from the input present state to the no input state, but the output state of the start signal is not changed and the output present state is maintained as it is. That is, even if the inverted clock signal is switched from the input present state to the no input state, the start signal is held in the output present state.

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

  When the start signal is switched to the output enabled state at timing t5, the CPU 102 detects the input of the start signal in the sensor monitoring process S107 of the timer interrupt process, and sets “1” in the first area 112a of the start detection area. To do. In step S518 of the start waiting process, it is determined that a start command has been generated, and a delay process is performed. In the delay process, a latch signal is output at timing td when the value of the first counter 111a becomes zero. That is, at the timing td after the delay time (specifically, the time obtained by multiplying the value of the first counter 111a by the timer interrupt period 1.49 msec) has elapsed since the CPU 102 determined that the start command was generated. The latch signal is switched from the no input state to the input present state. As a result, the operation timing of the start lever 41 and the timing at which the latch signal is output are shifted by the delay time.

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

  Here, in the random number generator 150, the count value of the counter 150a is updated at the timing (t1, t3, t6, etc.) when the second clock signal switches from the no-input state to the input-present state, and the count in the latch circuit 150b. The value latching is performed at a timing (t9) when the second clock signal switches from the input present state to the no input state. 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 41 returns to the initial position at the timing t10, the operation signal input to the monitoring circuit 152 switches from the input present state to the no input state. Since the timing t10 is a timing at which the inverted clock signal is switched from the input present state to the no input state, the output state of the start signal does not change at this timing. Then, at timing t11 when the inverted clock signal switches from the no-input state to the input-present state, it is detected that no operation signal is input, and the start signal switches from the output-present state to the no-output state. Note that when the inverted clock signal is not input (for example, timing t10 <timing t <timing t11), the operation signal is switched from the input input state to the no input state, or the inverted clock signal is input (eg timing Even when the operation signal is switched from the input present state to the no input state at t9 <timing t <timing t10), the start signal is switched from the output present state to the no output state at timing t11.

  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 41 cannot be accurately grasped. However, the start lever 41 in the slot machine 10 is configured to have several tens of milliseconds until the hand is released and returns to the initial position. When the start lever 41 is operated, an operation signal is at least several tens of milliseconds. The signal is input to the monitoring circuit 152. The clock frequency of the second clock signal output from the second clock circuit 151 is 7.915 MHz, and the period is about 126 nsec. In other words, the cycle in which the inverted clock signal is input in the monitoring circuit 152 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 152 even though the operation signal is output from the start lever detection sensor 41a.

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

  Returning to the description of the normal process, if it is determined that the start command is generated in the start wait process, the lottery process in step S405, the reel control process in step S406, the medal payout process in step S407, and the BB state process in step S408. Are executed in order, and the process returns to step S403.

  Next, the lottery process of step S405 will be described based on the flowchart of FIG.

  In step S601, a random number used for determining whether or not the winning combination is determined is acquired. That is, the random number generated by the random number generator 150 is stored in the random number storage area 110 composed of 2 bytes (16 bits). More specifically, the random number generator 150 latches the count value at the timing when the latch signal from the monitoring circuit 152 is input, and outputs the latched count value to the CPU 102. The CPU 102 stores the input count value as a random number in the random number storage area 110.

  Here, in the series of processing from step S108 to step S118 in the timer interrupt processing, the time required for performing the series of processing is input to the CPU 102 after the random number generator 150 latches the count value. It is configured so as to be longer than the time required for the operation. With this configuration, the acquisition timing of the random number generated by the random number generator 150 (the timing for performing the process of step S601) can be made later than the timing at which the count value latched in the current game is input to the CPU 102. In addition, the count value latched in the current game can be reliably stored in the random number storage area 110 as a random number.

  After acquiring the random number, in step S602, a lottery table for determining whether or not the winning combination is selected. Specifically, the current gaming state of the slot machine 10 is determined, and a lottery table corresponding to the gaming state is selected. The slot machine 10 is roughly divided into two game states, a normal state and a BB state, and a lottery table corresponding to each game state is selected. Further, when the setting state is “setting 1”, the lottery table with the lowest expected value of medal payout is selected, and when it is “setting 6”, the lottery table with the highest expected value of medal payout is selected.

  The lottery table will be briefly described. FIG. 24 is a normal state lottery table selected in the normal state of “setting 3”. In the lottery table, the same number of index values IV as the number of combinations to be determined are set. Each index value IV is uniquely associated with each winning combination, and a point value PV is set. ing. That is, in the normal state of the slot machine 10, the determination is made for six types of re-game, bell, watermelon, cherry, one-piece combination, and BB.

  After selecting the lottery table, the index value IV is set to 1 in step S603, and in the subsequent step S604, 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 initial determination value setting process, the random value created in step S601 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 S605, it is determined whether or not the combination corresponding to the index value IV is correct. In the combination determination, it is determined whether or not the determination value DV exceeds 65535. If 65535 is exceeded, the process proceeds to step S606, and the winning flag of the combination corresponding to the index value IV at that time is set in the winning flag storage area 106a of the RAM 106. For example, if the determination value DV exceeds 65535 when IV = 3, in step S606, the watermelon winning flag is set in the winning flag storage area 106a.

  By the way, if the winning flag that is set is one of the re-game winning flag, the bell winning flag, the watermelon winning flag, the cherry winning flag, or the one-piece winning flag, this winning flag is the game with the corresponding winning flag set. It is reset after completion (see S403 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 BB winning is established. That is, the BB winning flag may be valid for a plurality of games. In step S606 in the state where the BB winning flag is carried over, if the current index value IV is 1 to 5, the winning flag corresponding to the index value IV is set. If the current index value IV is 6, the BB winning flag is set. Do not set the flag. In other words, in a game in which the BB winning flag is carried over, when winning one of replay, bell, watermelon, cherry, or one-player combination, the corresponding winning flag is set, while when winning a BB The BB winning flag is not set.

  If the determination value DV does not exceed 65535 in step S605, 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 S607, and in the subsequent step S608, it is determined whether or not there is a combination corresponding to the index value IV, that is, whether or not there is a determination target to be determined. Specifically, it is determined whether or not the index value IV added by 1 exceeds the maximum value of the index values IV set in the lottery table. If there is a determination target to be determined whether or not, the process returns to step S604, and the determination of whether or not the winning combination is continued. At this time, in step S604, 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 determining whether or not the previous winning combination is a new determination value DV. In step S605, the winning combination determination is performed based on the determination value DV. By the way, in the case of performing the winning / failing determination using the lottery table shown in FIG. 24, the winning probability of BB is about 1/200, the winning probability of replay is about 7.30, and the winning probability of Bell is The winning probability for watermelon is about 1/18, the winning probability for watermelon is 1/128, the winning probability for cherry is about 73.0, and the winning probability for single-player is 1/128. In addition, the probability of losing no winning combination is about 1.36.

  After the winning flag is set in step S606, or when it is determined in step S608 that there is no determination target to be determined, it means that the determination of whether or not the winning combination has been completed. In such a case, a lottery result command is set in step S609. Here, the lottery result command is a command that is transmitted to the display control device 81 in order to grasp the result of the combination determination. By receiving the lottery result command, the display control device 81 executes drive control of the upper lamp 63 and the auxiliary display unit 65 to suggest a winning combination, for example. However, in the normal process, various commands such as the lottery result command are only set in the ring buffer, and the command is not transmitted to the display control device 81. The command transmission to the display control device 81 is performed in the command output process S110 of the timer interrupt process described above.

  In step S610, a slip table setting process for setting a reel table (stop table) for reel stop control is performed, and the lottery process is terminated. Here, the slip table is a table in which it is determined how much the reels 32L, 32M, and 32R are slid (rotated) and stopped from the timing when the stop switches 42 to 44 are operated. In other words, the slip table is a symbol that has reached the base point position (lower stage in the present embodiment) when the stop switches 42 to 44 are pressed, and actually stops at the base point position. This is a stop data group from which a relationship with a stop symbol (stop symbol number) can be derived.

  In the slot machine 10, as a stop mode for stopping the reels 32L, 32M, and 32R, when the stop switches 42 to 44 are operated, a stop mode for stopping the reaching symbol reaching the base position as it is is supported. Stop mode for stopping the reel to be slid after one symbol, Stop mode for stopping after sliding for two symbols, Stop mode for stopping after sliding for three symbols, Stop after sliding for four symbols There are prepared five patterns of stop modes. Then, a plurality of sliding tables each having one of the five patterns of stop modes set for each symbol number of each reel 32L, 32M, 32R are prepared for each combination.

  Thus, by setting the sliding table so that each reel 32L, 32M, 32R stops from when the stop switches 42 to 44 are operated until the specified time (190 msec) elapses, the display window 26L, It is possible to give the player an impression as if the symbol arrangement (hereinafter referred to as stop appearance) that stops within the range that can be visually recognized from 26M and 26R is determined by the player's operation. 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. At the same time, it is possible to prevent the combination of symbols corresponding to the combination not won in the lottery from stopping on the active line.

  FIG. 25 is an example of a sliding table that is set when the “replay” symbol of the left reel 32L is stopped on the active line. The symbol having the number of slips of 0 is a symbol that actually stops in the lower stage. For example, if the left stop switch 42 is operated while the 14th “watermelon” symbol of the left reel 32L reaches the lower stage, the left reel 32L stops without slipping and the 16th “replay” symbol. Stops at the top. In addition, a symbol whose number is not zero means that the reel slides by the number of symbols described. For example, if the left stop switch 42 is operated while the 8th “bell” symbol of the left reel 32L has reached the lower stage, the left reel 32L slides by 4 symbols and the 12th “replay” symbol is displayed. Stop at the bottom. As described above, in the slip table, the number of slips when the stop switches 42 to 44 are operated at the timing when the symbols attached to the reels 32L, 32M, and 32R reach the lower stage is set for each symbol number.

  In the smooth table setting process, the winning flag set in the winning flag storage area 106a of the RAM 106 is confirmed, and the smooth table uniquely corresponding to the set winning flag is stored in the smooth table storing area 106b of the RAM 106. set. At this time, in the slot machine 10, the middle reel 32 </ b> M and the right reel 32 </ b> R so that the symbol corresponding to the winning combination of the left reel 32 </ b> L (hereinafter referred to as “winning symbol”) stops at either the upper stage or the lower stage. Set the sliding table set so that the winning symbol of stops at the middle. Here, setting the sliding table set so that the winning symbol of the left reel 32L stops at either the upper stage or the lower stage generally rotates in the order of the left reel 32L → the middle reel 32M → the right reel 32R. This is to diversify the stop output in consideration that the stop switches 42 to 44 are operated to stop the operation.

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

  The “replay” symbol is arranged on each of the reels 32L, 32M, and 32R so that the interval between the symbol that reaches the lower stage first and the symbol that reaches the next is 4 symbols or less. For example, the 4th “replay” symbol and the 7th “replay” symbol of the left reel 32L are arranged so that the interval is 2 symbols, and the 1st “replay” symbol of the middle reel 32M and 6 The “replay” symbols of the numbers are arranged so that the interval is 4 symbols. As described above, the “replay” symbols are arranged on the reels 32L, 32M, and 32R so that the interval between the symbols of the same type is 4 symbols or less. As described above, the reels 32L, 32M, and 32R can be stopped after sliding up to four symbols at the timing when the stop switches 42 to 44 are operated. Therefore, by adopting such a symbol arrangement, the “replay” symbol can be stopped at an arbitrary position when the replay winning is established, regardless of the timing at which the stop switches 42 to 44 are operated. . For example, when the middle stop switch 43 is operated when the first “replay” symbol of the middle reel 32M reaches the lower level, the “replay” symbol can be stopped at the lower level if the middle reel 32M is stopped as it is. If the middle reel 32M is slid after 3 symbols and then stopped, No. 6 "Replay" symbol can be stopped at the upper stage, and if the middle reel 32M is slid after 4 symbols and then stopped, No. 6 The “replay” symbol can be stopped in the middle.

  In the slot machine 10, in addition to the “replay” symbols, the “bell” symbols are also arranged on the reels 32 </ b> L, 32 </ b> M, and 32 </ b> R so that the intervals between the same symbols are 4 symbols or less. For this reason, even if the stop switches 42 to 44 are operated at any timing, the “bell” symbol can be stopped at an arbitrary position when the bell winning is established.

  On the other hand, the “watermelon” symbols are not arranged on the reels 32L, 32M, and 32R so that the interval between the symbols of the same type is 4 symbols or less. For this reason, for example, when the left stop switch 42 is operated when the third “red 7” symbol of the left reel 32L has reached the lower stage, even if the left reel 32L is slid by four symbols, the “watermelon” The symbol cannot be stopped on the active line. Therefore, even if the watermelon is won and the slide table set so that the “watermelon” symbol stops on the active line is set, depending on the timing of operation of the stop switches 42 to 44, “watermelon” There is a case where a symbol does not stop on the active line and a so-called spillover occurs in which a watermelon winning is not established. In the slot machine 10, in addition to the “watermelon” symbol, the “red 7” symbol is also arranged on each reel 32 </ b> L, 32 </ b> M, 32 </ b> R so that a section separated by 5 symbols or more is formed. Further, in the left reel 32L, the “cherry” symbols are arranged so as to form a section separated by 5 symbols or more, and in the middle reel 32M, the “youth” symbols form a section separated by 5 symbols or more. In the right reel 32R, the “white 7” symbols are arranged so as to form a section separated by 5 symbols or more. For this reason, when any one of BB, watermelon, cherry, and one winning combination is won, it is necessary to operate the stop switches 42 to 44 so as to stop the winning symbol on the active line.

  Returning to the description of the smooth table setting process, when the BB winning flag and other winning flags are set, the following smooth table is set.

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

  When the BB winning flag and the small role winning flag (that is, any one of the bell winning flag, the watermelon winning flag, the cherry winning flag, and the one-sheet winning flag) are set, the BB for preferentially establishing the BB winning. Set the priority winning slide table. However, since the “Red 7” symbol, which is the BB symbol, is arranged on each of the reels 32L, 32M, and 32R so as to form a section separated by five symbols or more as described above, it depends on the operation timing of the stop switches 42 to 44. May not be able to stop the “Red 7” symbol on the active line. Therefore, in the BB priority winning slide table, the reels 32L, 32M, and 32R are set as follows. For the left reel 32L, if it is possible to stop both the “red 7” symbol and the winning small role symbol on the active line, “red 7” so that both symbols are preferentially stopped on the active line. It is impossible to stop the “Red 7” symbol at the upper or lower level, so that if the symbol can be stopped at either the upper level or the lower level, it will be impossible to stop the symbol. If it is possible to stop at each position, the winning small role symbol is set to stop at each position. The middle reel 32M and the right reel 32R are set so that the “red 7” symbol is stopped preferentially if possible, and the “red 7” symbol is placed at each position. If it is impossible to stop and the winning small symbol can be stopped at each position, the winning small symbol is set to stop at each position.

  Next, the reel control processing in step S406 will be described based on the flowchart of FIG.

  In the reel control process, first, in step S801, a rotation start process for starting the rotation of each reel 32L, 32M, 32R is performed. Here, the rotation start process will be described with reference to the flowchart of FIG.

  In the rotation start process, in step S901, it is confirmed whether or not a wait time (for example, 4.1 seconds) determined when starting the previous game has elapsed. If not, the wait time elapses. Wait until. If the wait time has elapsed, the process proceeds to step S902 to reset the wait time for the next game. Thereafter, in step S903, 25 is set in the acceleration counter provided in the RAM 106. Although details will be described later, by performing such processing, the acceleration processing of the stepping motor is started in the stepping motor control processing S106 of the timer interruption processing, and the reels 32L, 32M, and 32R start to rotate. For this reason, even if the player bets a specified number of medals and operates the start lever 41, the reels 32L, 32M, and 32R may not immediately start rotating. Thereafter, in step S904, it is determined whether or not each of the reels 32L, 32M, and 32R has started rotating, and waits until the rotation starts. That is, in step S904, after the acceleration counter is set to 25, the process waits until timer interrupt processing is performed. When the reels 32L, 32M, and 32R start to rotate, a start flag is set in step S905, and the process waits until the reels 32L, 32M, and 32R rotate at a predetermined rotation speed at step S906. . Then, when the reels 32L, 32M, and 32R are rotated at a constant speed, the rotation start process is terminated. In addition, when the rotation speed of each of the reels 32L, 32M, and 32R reaches a constant speed, the CPU 102 can generate a stop command by lighting up a lamp (not shown) of each stop switch 42 to 44. Is notified to a player or the like.

  Following the rotation start process, a stop pre-process is performed in step S802.

  In the pre-stop process, as shown in the flowchart of FIG. 28, first, an interrupt wait process is performed in step S1001. In the subsequent step S1002, it is determined whether or not a start command is generated, more specifically, whether or not “1” is set in the first area 112a of the start detection area. If “1” is set in the first area 112a of the start detection area, the process returns to the interrupt waiting process in step S1001. That is, when “1” is set in the first area 112a of the start detection area, the process does not proceed to step S1003 and subsequent steps until the first area 112a of the start detection area is changed to “0”.

  Incidentally, as a situation where it is determined that the start command is generated in step S1002, the process of step S518 is performed when the start lever 41 remains pressed from the processing timing of step S518 to the processing timing of step S1002. When the start lever 41 is operated again after a short time, there may be a case where some abnormality occurs in the monitoring circuit 152 or the like and the start signal remains output.

  If no start command has been generated, the process proceeds to step S1003 to determine whether any of the stop switches 42 to 44 has been operated. More specifically, the one-area reference process of the operation determination process described above is performed for each of the stop switches 42 to 44. For example, as to whether or not the left stop switch 42 is operated, the first area 112a of the left stop detection area is referred to. If “1” is stored, it is determined that the left stop switch 42 has been operated, and “0 "Is stored, it is determined that the left stop switch 42 has not been operated. If none of the stop switches 42 to 44 is operated, the process returns to the interrupt waiting process in step S1001. If it is determined that any of the stop switches 42 to 44 has been operated, the process proceeds to step S1004 to determine whether or not the stop switch corresponding to the rotating reel has been operated, that is, whether or not a stop command has been issued. To do. If no stop command has been generated, the process returns to the interrupt waiting process in step S1001, and if a stop command has been generated, a command flag is set in step S1005. The command flag is cleared in the sensor monitoring process S107 of the timer interrupt process described above. More specifically, in the sensor monitoring process, when a command flag is set, a detection flag corresponding to the stop detection sensor to which the ON signal is input at that time is set. When the input of the ON signal from the stop detection sensor corresponding to the detection flag is completed, the detection flag and the command flag are cleared. If the command flag is set, the process proceeds to step S1006 to determine whether or not the current stop command is the third stop command, that is, whether or not the stop switch has been operated when only one reel is rotating. . If the current stop command is the third stop command, an affirmative determination is made in step S1006, and the pre-stop processing is terminated as it is. On the other hand, in the case of the first stop command that is generated when all the reels 32L, 32M, and 32R are rotating or the second stop command that is generated when two reels are rotating, the result is negative in step S1006. In addition to making the determination, the first change process of the slip table is performed in step S1007, and the pre-stop process is terminated.

  Here, the first change process of the slide table is a process of changing the slide table stored in the slide table storage area 106b of the RAM 106 before stopping the reel corresponding to the stop command. In the first change process of the slide table, it is assumed that the slide table is set in the slide table storage area 106b, for example, when the first stop command is generated by operating the stop switches 43 and 44 other than the left stop switch 42. When the stop switches 42 to 44 are operated in an operation order different from the operation order of the stop switches 42 to 44, the sliding table is changed. By performing such processing, diversification of stoppages can be achieved, or the frequency of occurrence of so-called spillovers in which the winning flag is invalidated without establishing a winning corresponding to the set winning flag can be reduced. Can do.

  Returning to the description of the reel control process, when the pre-stop process is completed in step S802, it means that the stop switch corresponding to the rotating reel is operated to advance the game, and a stop command is generated. In such a case, stop control processing shown in steps S803 to S809 is performed to stop the rotating reel.

  That is, in step S803, the symbol number of the symbol that has reached the lower stage at the timing when the stop switch is operated is confirmed. Specifically, the symbol number of the reaching symbol reaching the lower stage is confirmed by the number of excitation pulses output from the time when the detection signal of the reel index sensor is input. In subsequent step S804, the number of slips of the reel to be stopped this time is calculated from the data of the symbol number corresponding to the reaching symbol among the slip tables set in the slip table storage area 106b. After that, in step S805, the calculated number of slips is added to the symbol number of the reaching symbol, and the symbol number of the stop symbol that is actually stopped at the lower stage is determined. In step S806, 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 S807. Do. Note that the process of actually stopping the rotation of the reel is performed in the stepping motor control process S106 of the timer interrupt process. In the reel stop process in the normal process, a process of waiting until the reel to be stopped this time is stopped is performed. Yes. Thereafter, in step S808, it is determined whether or not all the reels 32L, 32M, and 32R are stopped. If all the reels 32L, 32M, 32R are not stopped, the slide table second change process is performed in step S809, and the process returns to the pre-stop process in step S802.

  Here, the second change process of the slide table is a process of changing the slide table stored in the slide table storage area 106b of the RAM 106 after the reels are stopped. In the second change process of the slide table, the slide table is changed based on the set winning flag and the stoppage of the stopped reel. For example, when the bell winning flag is set and the “bell” symbol of the left reel 32L stops at the upper stage, the “bell” symbol of the middle reel 32M is changed to a sliding table set to stop at the upper or middle stage. By performing such a process, it is possible to diversify the reel stop appearances to be stopped later according to the result of the reel stop, and to reduce the frequency of occurrence of missing.

  On the other hand, if it is determined in step S808 that all the reels 32L, 32M, and 32R are stopped, a payout determination process is performed in step S810, and this process is terminated. The payout determination process is a process of setting the number of medals to be paid out as one of the conditions that a combination of winning symbols is arranged on an active line.

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

  Here, a specific process for actually rotating and stopping each of the reels 32L, 32M, and 32R, that is, a stepping motor control process performed in a timer interrupt process will be described.

  In the stepping motor control process, a motor control process for generating a drive signal for rotation control for the stepping motor (specifically, excitation data to be described later, hereinafter referred to as excitation data) is performed, and the generated excitation data is temporarily stored. The data is stored in the RAM 106. Such motor control processing is executed for each of the reels 32L, 32M, and 32R in the order of the left reel 32L, the middle reel 32M, and the right reel 32R. When the generation of excitation data for all the reels 32L, 32M, and 32R is completed, the excitation data stored in the RAM 106 is output to the input / output port 104. Since the output to the input / output port 104 is a data writing process to the corresponding output port of the input / output port 104, the excitation data was supplied to the stepping motor simultaneously with the writing of the excitation data to the input / output port 104. It will be. As a result, the stepping motor immediately energizes the excitation phase specified by the excitation data, and the reel rotates or stops.

  FIG. 29 is a specific processing example of the motor control processing described above. In this motor control process, at least a wait timer, an acceleration counter, and an excitation order pointer (all of which are software processes using the RAM 106) are used.

  The wait timer is a timer for measuring a holding time (more specifically, the number of timer interruptions) for holding the stepping motor in the same excitation mode. The acceleration counter is a counter for designating the holding time, and the relationship between the value of the acceleration counter and the holding time is stored in advance in the ROM 105 as an acceleration counter table. The stepping motor in the present embodiment has a configuration that requires an excitation pattern of 25 steps from the stop state to the constant speed state, and the acceleration counter table includes values of acceleration counters “0” to “24”. And the number of timer interrupts set in the wait timer are defined. The excitation order pointer is a pointer used when determining the excitation phase for the stepping motor. When the 1-2 phase excitation stepping motor is used, the 1 phase excitation and the 2 phase excitation are alternately performed, and the phase excitation pattern at that time is 8 patterns. The ROM 105 stores in advance an excitation data table that defines the correspondence between excitation order pointers “0” to “7” and excitation data to be output. Then, according to the value of the excitation order pointer, which excitation data is to be acquired as output excitation data at which phase excitation is to be acquired and stored in the RAM 106 is designated.

  The motor control process of FIG. 29 will be described in relation to the progress of the game. The following description is only an example of processing for a stepping motor for controlling one reel.

  First, processing in a state where no start command is generated, that is, a state where the game is not started will be described.

  The value of the wait timer before the start lever 41 is operated is 0, and the value of the acceleration counter is also 0. For this reason, an affirmative determination is made in the determination process of whether or not the wait timer is 0 in step S1101, and the process proceeds to step S1103. In step S1103, it is determined whether or not the value of the acceleration counter is not 0, but this determination is negative, and the process proceeds to step S1104. In step S1104, the output excitation data is set to “0”, and this process ends. As a result, until the start command is generated, the stepping motor maintains the stopped state, and the reels 32L, 32M, and 32R remain stopped.

  Next, a process when a start command is generated, more specifically, a process until the reel is shifted from the stopped state to the constant speed state will be described.

  When it is determined that a start command is generated in the normal process start wait process (when an affirmative determination is made in step S518), "25" is set in the acceleration counter in the rotation start process. Since the value of the wait timer remains 0 at such time, an affirmative determination is made in step S1101, and the process proceeds to step S1103. In step S1103, the value of the acceleration counter is determined. Since “25” is set in the acceleration counter, an affirmative determination is made in step S1103, and 1 is subtracted from the value of the acceleration counter in step S1105. In step S1106, it is determined again whether the value of the acceleration counter is not zero. Since the value of the acceleration counter at this time is “24”, an affirmative determination is made and processing proceeds to step S1108. In step S1108, the excitation time at the acceleration counter value “24” is referred to from the acceleration counter table, and this excitation time (“130” in the present embodiment) is set in the wait timer. When the setting of the wait timer is completed, an update process for adding 1 to the excitation order pointer is executed in step S1109. In step S1110, excitation data corresponding to the updated excitation order pointer value is acquired from the excitation data table, and the excitation data is stored in the RAM 106 as output excitation data. The stored excitation data is simultaneously output to the input / output port 104 after the excitation data for the stepping motors of all reels is acquired. Thereafter, the symbol offset value is updated in step S1111 and a reel rotation detection process by the reel index sensor shown in step S1112 and subsequent steps is performed. Of these steps, steps S1118 and S1119 are reel abnormality processing, and processing is performed in a case where the reel does not rotate normally despite the excitation data being applied. Steps S1120 to S1123 are steps for stopping rotation of the stepping motor. Processing (brake processing). These processes will be described later. If the motor acceleration process is normal, steps S1118 to S1123 are skipped, and the process returns to the timer interrupt process shown in FIG.

  As described above, when the start command is generated, the counter value “25” is set in the acceleration counter, and excitation data for starting the motor is supplied to the stepping motors corresponding to the three reels 32L, 32M, and 32R. Is supplied, rotation of the reel is started. In the next timer interrupt process, the motor control process is called again. The processing at this time will be described next.

  In the next motor control process, since the value of the wait timer is “130”, an affirmative determination is made in step S1101 and the process proceeds to step S1102, where the value of the wait timer is decremented by 1, and the process returns to the timer interrupt process. As a result, the values of the acceleration counter and the excitation order pointer are kept the same as those at the previous timer interruption, and the stepping motor remains excited with the same excitation phase (the reel does not rotate). This process using the same excitation phase is continuously performed for a total of 130 interrupts, and the value of the wait timer becomes zero when 130 interrupts are performed.

  On the other hand, the value of the acceleration counter does not change during the period. When the 130 interrupt ends and the value of the wait timer becomes 0, the process proceeds to step S1105 via step S1103, and the acceleration counter is subtracted. Thereafter, in step S1106 and step S1108, the excitation time (“8” in the present embodiment) corresponding to the acceleration counter value “23” subtracted by 1 is acquired from the acceleration counter table, and the acquired excitation time value ( = 8) is set in the wait timer. In steps S1109 to S1112, the value of the excitation order pointer is updated by 1, and the excitation data corresponding to this excitation order pointer value is stored in the RAM 106 as output excitation data. The stored excitation data is simultaneously output to the input / output port 104 after the excitation data for the stepping motors of all reels is acquired. By updating the excitation order pointer, the output excitation data, that is, the excitation phase is changed, and the reel rotates by one step angle. In the motor control process after the next time, the wait timer is subtracted in step S1102 until the wait timer becomes 0 again, and when it becomes 0, the acceleration counter subtraction process, the excitation order pointer update process, etc. are performed. Do.

  Thus, when the reel is rotated from the stop state, the same excitation phase is maintained until the excitation time corresponding to the value of the acceleration counter elapses, and the excitation order pointer is changed when the excitation time elapses. Change the excitation phase with. This is a device for eliminating step-out and rotation instability.

  When the value of the acceleration counter is sequentially subtracted, the value of the acceleration counter eventually becomes “0”. If the value of the acceleration counter becomes “0” as a result of the subtraction process in step S1105, a negative determination is made in step S1106, and the process proceeds to step S1107. In step S1107, “1” is set in the acceleration counter. Thereafter, the process proceeds to step S1108, and a value (“1” in the present embodiment) corresponding to the excitation time corresponding to the acceleration counter value “0” subtracted in step S1105 is set in the wait timer. Thereafter, in steps S1109 and S1110, the excitation order pointer is updated and the corresponding excitation data is read out and set as output excitation data.

  If the value of the acceleration counter becomes “0” in step S1105, the value of the acceleration counter is changed to “1” in step S1107. Therefore, in the subsequent motor control processing, when the value of the wait timer becomes 0, the process proceeds to step S1105 via step S1103, and 1 is subtracted from the value of the acceleration counter. As a result, the value of the acceleration counter becomes “0” again, and in step S1108, the value corresponding to the excitation time corresponding to the acceleration counter value “0” (“1” in this embodiment) is set again in the wait timer. Is done. Moreover, since the excitation order pointer is updated in step S1109, the excitation phase is switched.

  As described above, when the value of the acceleration counter is sequentially subtracted from “25” to become “0”, in the subsequent motor control processing, the acceleration counter values “0” and “1” are set in steps S1105 and S1107. While the addition / subtraction processing is alternately repeated, the excitation time of the acceleration counter “0” is always set in the wait timer in step S1108. In addition, since the excitation data is updated every time in steps S1109 and S1110, the stepping motor is in a rotation mode in which one-phase excitation and two-phase excitation are periodically and alternately repeated. This is nothing but the constant speed process. In other words, when the motor control process is performed until the value of the acceleration counter becomes “0”, each reel 32L, 32M, 32R shifts to the constant speed state thereafter. Will do.

  Next, processing when a stop command is generated will be described.

  When the player operates a stop switch corresponding to the rotating reel and a stop command is generated while the reel is rotating at a constant speed, the rotation of the corresponding reel is rotated by the rotation stop process shown in steps S1120 to S1123. Stop.

  Prior to the description of the rotation stop process, the symbol offset and symbol number will be described. When excitation data is acquired in step S1110, the symbol offset value is updated in step S1111 and reel rotation detection processing by the reel index sensor is performed in step S1112. That is, in step S1112, it is confirmed whether or not the reel index sensor has detected the passage of the sensor cut van, and specifically, whether or not a detection signal indicating that the passage has been detected is input. When the detection signal is input, it means that the reel has made one rotation. In such a case, the start flag is cleared in step S1113, and the values of the symbol offset counter and symbol number counter are reset to 0 in step S1114.

  The symbol number indicates a symbol number by a serial number, and takes a value of “0” to “20” in the slot machine 10 with 21 symbols. The number given for convenience of explanation in FIG. 6 is the symbol number. The symbol offset is a value obtained by dividing one symbol into 24 equal parts in the rotation direction of the reel, and takes a value of “0” to “23”. If the symbol offset value is “24”, a negative determination is made in step S1115, the symbol number is updated in step S1116, and the symbol offset value is reset to zero.

  Now, even if the brake is applied to stop the rotation of the reel, the stepping motor slips for 3 to 4 steps because it slips on the rotor of the stepping motor. Therefore, when the symbol number update or symbol offset is reset in step S1116, it is determined in step S1120 whether it is time to stop the reel. Specifically, it is determined whether the excitation phase currently being output is two-phase excitation and whether the symbol offset value is within a predetermined offset value. Whether or not the current excitation phase is two-phase excitation is determined by referring to the value of the excitation order pointer, and whether or not the predetermined offset value is exceeded is determined by referring to the symbol offset value. The symbol offset value is taken into account because the larger the symbol offset value, the greater the relative deviation of the symbol position from the adjacent reel at the time of stoppage. When the human discriminating power exceeds 4 offsets, it becomes possible to clearly recognize the shift of the symbols. Therefore, when the symbol offset value is 4 or less, the rotation stop process is executed.

  If the above conditions are not satisfied, it is determined that it is not a time when the reel can be stopped, and this process is terminated and the process returns to the timer interrupt process. If the above conditions are satisfied, the process proceeds to step S1121. As described above, when a stop command is generated, a stop symbol number is determined in the reel control process of the normal process. In step S1121, the current symbol number is compared with the determined stop symbol number. If both symbol numbers do not match, this process is terminated and the process returns to the timer interrupt process. If both symbol numbers match, a brake setting process is performed in step S1122. In the brake setting process, brake excitation data is set. Also, the brake time is set in the wait timer. In this embodiment, 159 interrupt (= 236.91 msec) is set as the brake time, and “159” is set in the wait timer. In addition, the acceleration counter is reset (= 0). When the wait timer is set to the above-described value (= 159), the processes of steps S1101 and S1102 are performed for 159 interrupts. During this period, the brake excitation data is continuously output, whereby the rotor of the stepping motor is completely stopped and the reel is stopped.

  When the brake setting process is completed, the excitation order pointer adjustment process is performed in step S1123, and the process returns to the timer interrupt process. The excitation order pointer adjustment process is a process for setting an excitation order pointer to be referred to when the next rotation starts. As described above, the rotor of the stepping motor slides for about 3 to 4 steps and then stops when the brake is applied. For this reason, in the excitation order pointer adjustment process, a process of adding 4 to the current excitation order pointer is performed.

  At the end of the motor control process, a process when an abnormality occurs in the rotation of the reel will be described.

  As already explained, during the acceleration period before the reel rotates at a constant speed, the symbol offset value is updated according to the addition / subtraction of the acceleration counter, and after the constant speed rotation, the timer interrupt (motor control processing) The symbol offset value is updated each time. When the symbol offset value becomes “24”, the symbol number is updated and the symbol offset value is reset. When it is detected that the reel has made one revolution, the symbol number and the symbol offset value are reset. By performing these processes, it is possible to determine which symbol is visible through the display window based on the symbol number value, and which range of the symbol is visible from the display window according to the symbol offset value. I know if it is. For example, in the case of the symbol number “0” and the symbol offset “0”, symbols of symbol numbers “0” to “2” are visible from the display window.

  In the case of normal rotation in which the stepping motor is normally accelerated by the generation of the start command and reaches constant speed rotation, the situation as described above is reproduced. However, when the acceleration is not normally performed or when the reel is intentionally pressed and the rotation is stopped, the following abnormal rotation processing is performed.

  First, as described above, the reel rotates once by the excitation signal of 504 pulses. Therefore, when normal rotation is performed, the detection signal is input again when the excitation signal of 504 pulses is output after the detection signal from the reel index sensor is input. However, when the acceleration is not normally performed and the reel does not start rotating, or when the reel is intentionally pressed to stop the rotation, the detection signal is output even if a 504 pulse excitation signal is output. Not entered. As a result, since the symbol number reset process in step S1114 is not performed, the symbol number exceeds the maximum value “20” and is updated to “21” in step S1116. Even if the value of the symbol number becomes “21”, the counter addition / subtraction processing is performed in the next processing, so that the symbol offset value is updated as before.

  In such a case, after step S1115, the value of the symbol number is determined in step S1117. Since the symbol numbers are from “0” to “20”, when the symbol number is “21”, it can be regarded as an abnormal rotation state. However, since the cause of the abnormal rotation state may be due to variations in the operation of the stepping motor, it is further determined in step S1118 whether or not the value of the symbol offset has been updated by 4 offsets or more. It is determined that the rotation state is abnormal, and the abnormality process in step S1119 is performed. In the abnormal process, the initial value “25” is set in the acceleration counter, and the acceleration process is performed again from the next timer interruption period. Incidentally, there are variations in the operation of stepping motors, and ideally one rotation = 504 pulses, but in some cases, one rotation with 503 pulses or 505 pulses may be considered. Therefore, in step S1117, four offsets are set as abnormality detection values with a margin.

  Next, the medal payout process in step S407 will be described with reference to the flowchart of FIG.

  In step S1201, it is determined whether the planned number of payouts set in the payout information storage area matches the actual number of payouts. If they do not match, it means that a winning for paying out medals has been established, and the corresponding number of medals has not been paid out. In such a case, the process proceeds to step S1202, and a payout start flag is set. In subsequent step S1203, it is determined whether or not the count value of the credit counter has reached the upper limit (the number of stored medals is 50). If the upper limit has not been reached, 1 is added to the count value of the credit counter in step S1204, and 1 is added to the count value of the payout number counter for counting the number of payouts in step S1206. Return. By performing such processing, 1 is added to each value of the credit display unit 60 and the payout number display unit 62. On the other hand, if the count value of the credit counter has reached the upper limit, or if the count value of the credit counter has reached the upper limit during the addition of the number of payouts, the process proceeds to step S1205 to drive the medal payout rotary plate, The medal is paid out from the hopper device 51 to the medal tray 50 through the medal discharge port 49. Thereafter, in step S1206, the count value of the payout number counter is incremented by 1, and the process returns to step S1201. By performing such processing, one actual medal is paid out and the value of the payout number display section 62 is incremented by one. When the hopper device 51 is driven to actually pay out medals, the payout number is incremented by 1 according to the medal detection signal of the payout detection sensor 51a attached to the hopper device 51. If the current gaming state is the BB state, in the medal payout process, the payout number is subtracted from the value of the remaining payout number counter, which will be described later, and the remaining payout number displayed on the remaining payout number display unit 61 is calculated. A subtraction process is also performed.

  If the number of payouts coincides with the planned payout number in step S1201, it means that the game has been completed by paying out the number of medals corresponding to the established winning, or the game has been finished without paying out medals. Therefore, the payout start flag is cleared in step S1207, the game flag is cleared in step S1208, and this process ends.

  Next, the BB state process of step S408 will be described based on the flowchart of FIG.

  Prior to the description of the BB state process, the BB state will be described. The BB state is composed of a plurality of RB states. The RB state consists of 12 JAC games. A JAC game is a game in which the probability that a prize (for example, a bell prize or the like) to which a medal payout privilege is granted is established is higher than that in a normal state. If the winning is established 8 times during the JAC game, the RB state is ended even before the JAC game is played 12 times. Further, the BB state ends when the number of medals paid out reaches a predetermined number (specifically, 400). In addition, when the number of medals paid out reaches a predetermined number in the middle of the RB state, not only the BB state but also the RB state ends. This is a contrivance for suppressing the player's euphoria by giving an upper limit to the number of medals paid out during the BB state, and ensuring the soundness of the game. Further, in the present embodiment, the combination of symbols that shift to the RB state is not set, and the configuration shifts to the RB state immediately after the transition to the BB state and immediately after the RB state ends. Therefore, it can be said that the BB state is a game that continuously shifts to the RB state until a predetermined number of medals are paid out.

  In the BB state process, first, in step S1301, it is determined whether or not the current gaming state is the BB state. If not in the BB state, BB determination processing shown in steps S1302 to S1305 is performed.

  In the BB determination process, it is determined in step S1302 whether or not the BB winning flag is set. If the BB winning flag is set, the process proceeds to step S1303, and it is determined whether or not a BB winning has been established based on the winning combination set in the previous payout determination process. If a BB winning is established, a BB start process is executed to shift the gaming state to the BB state in step S1304. Specifically, the BB winning flag is cleared and the BB setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the BB state. Further, a process of setting 400 in the remaining payout counter for counting the remaining number of medals that can be paid out during the BB state provided in the state information storage area 106c and displaying 400 on the remaining payout number display unit 61. I do. Thereafter, an RB start process is performed in step S1305, and the BB state process is terminated. In the RB start process, the RB setting flag is set in the state information storage area 106c of the RAM 106, and the gaming state is set to the RB state. In addition, 8 is set in the remaining payout payout counter for counting the number of winnings established in the RB state, and 12 is set in the remaining JAC game counter for counting the number of remaining JAC games. The remaining payout / winning counter and the remaining JAC winning counter are provided in the state information storage area 106c. In addition, the determination of the current gaming state in step S1301 or the like is executed based on whether or not the setting flag corresponding to the state information storage area 106c is set, and when any setting flag is not set. Determines that the current gaming state is the normal state.

  On the other hand, when the BB winning flag is not set (when step S1302 is NO) or when the BB winning is not established (when step S1303 is NO), the BB start process or the like is not executed. The process ends.

  If it is determined in step S1301 that the current gaming state is the BB state, the process proceeds to step S1306, where it is determined whether or not a winning has been established based on the winning winning combination set in the previous payout determining process. . If a winning is achieved, 1 is subtracted from the value of the remaining payout winning counter in step S1307. After that, or when it is determined in step S1306 that no winning has been established, one JAC game has been consumed. In step S1308, the value of the remaining JAC game counter is decremented by one. In step S1309, it is determined whether either the remaining payout / winning counter or the remaining JAC game counter has become zero. If any of them is 0, that is, if the winning is achieved 8 times or the JAC game is digested 12 times, it means that the RB state end condition is satisfied, so in step S1310, the remaining payout winning / counting counter Then, an RB end process for clearing the value of the remaining JAC game counter is performed. In subsequent step S1311, it is confirmed whether or not the count value of the remaining payout counter is zero. If it is not 0, it means that the number of medals paid out during the BB state has not reached the predetermined number and the end condition for the BB state is not satisfied. After performing the processing, the present processing is terminated.

  In step S1309, when both the remaining payout / winning counter and the remaining JAC game counter are not 0, that is, when the winning has not been established 8 times and the JAC game has not been digested 12 times, step S1313 is executed. Then, it is confirmed whether or not the count value of the remaining payout counter is 0. If it is not 0, it means that the number of medals paid out during the BB state has not reached the predetermined number and the end condition for the BB state is not satisfied. On the other hand, when the count value of the remaining payout counter is 0, it means that the BB state end condition is satisfied, and therefore, the special game state end process shown in steps S1314 to S1315 is performed. In the special game state end process, first, in step S1314, the above-described RB end process is performed. Thereafter, in step S1315, a BB end process is performed for appropriately clearing the BB setting flag, various counters, etc. or performing an ending process. Also, when the count value of the remaining payout number counter is 0 in step S1311, it means that the BB state end condition is satisfied, and therefore the BB end process is performed in step S1315. After performing the BB termination process, the state transition process is executed in step S1316, and the BB state process is terminated. Here, the state transition process is a process for returning the gaming state to the normal state. For example, an end command transmitted to make the display control device 81 know that the BB state has ended, A process of waiting until a time (for example, a time until the ending display ends) elapses is performed.

  Finally, the counter update process performed in step S116 of the timer interrupt process will be described based on the flowchart of FIG.

  In step S1401, it is determined whether a delay flag is set. When the delay flag is set, in order to perform the process of subtracting the value of the first counter 111a in the delay counter process S117 of the timer interrupt process, the process of adding 1 to the value of the first counter 111a is performed. This process is finished as it is. If the delay flag has not been set, it is further determined in step S1402 whether or not the game flag has been set. If the game flag has not been set, the process is terminated. On the other hand, when the game flag is set, addition processing shown in steps S1403 to S1409 is performed. As described above, the game flag is a flag that is set when a start command is generated, that is, when the game is started, and is cleared when the medal payout is completed, that is, when the game is ended. is there. That is, in the counter update process, the addition process is performed when the game is being played, while the addition process is not performed when the game is not being played.

  If the game flag is set, the process proceeds to step S1403, and 1 is added to the value of the first counter 111a. In step S1404, it is determined whether a command flag is set. When the command flag is set, the start lever 41 is continuously operated after the start command is generated, or the stop switch that generates the stop command is continuously operated after the stop command is generated. That means. In such a case, the process proceeds to step S1405, and 1 is added to the value of the first counter 111a. After updating the first counter 111a or when the command flag is not set, the process proceeds to step S1406, and it is determined whether or not the start flag is set. When the start flag is set, it means that the detection signal from the reel index sensor is not input after the rotation of each of the reels 32L, 32M, 32R is started. In such a case, the process proceeds to step S1407, and 1 is added to the value of the first counter 111a. After updating the first counter 111a or when the start flag is not set, the process proceeds to step S1408, and it is determined whether or not the payout start flag is set. If the payout start flag is set, this means that the medal payout has not been completed. In such a case, the process ends after adding 1 to the value of the first counter 111a in step S1409. If the payout start flag is not set, the process ends.

  Thus, in the counter update process in the timer interrupt process, the first counter 111a is updated based on the progress of the game. More specifically, the first counter 111a is not updated when the game is not being played, and the first counter 111a is updated when the game is being played and the delay process is not being performed. . Further, since the counter update process is a process included in the timer interrupt process periodically performed every 1.49 msec, the first counter 111a is periodically set to 1 in step S1403 in a situation where a game is being performed. Updated. In addition, a corresponding switch (start lever 41) from when the reel 32L, 32M, 32R starts to rotate until a detection signal is input from the reel index sensor and after a start command or stop command is generated. In addition, the period until the operation of the stop switches 42 to 44) is completed and the period from when the medal payout is started until it is ended, in addition to the periodic update of the first counter 111a in step S1403 described above. In addition, the first counter 111a is further updated. That is, in the counter update process of the timer interrupt process, there are a case where the first counter 111a is updated by 1 and a case where two or more are updated depending on the progress of the game.

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

  When the start lever 41 is operated and a start command is generated, the count value of the random number generator 150 is latched not at the operation timing of the start lever 41 but at the timing after the delay time has elapsed from the operation timing. The configuration. Since the delay time varies depending on the value of the first counter 111a, such a configuration makes it possible to latch the count value of the random number generator 150 even if the start lever 41 is operated at a constant period. Can be changed. As a result, when the random number to be won is generated by using a sensory device or the like, the main control device is operated at the timing when the start lever 41 is manipulated or when the count value is generated. It is possible to make it difficult to attach an unauthorized board capable of outputting an unauthorized signal that misrecognizes that a start command has occurred in 101, and to make it difficult to obtain a random number to win Is possible.

  The value of the first counter 111a is updated between the start of the game and the end, and when the next game is started, the random number acquisition timing is set using the updated value of the first counter 111a. The configuration is delayed. In such a configuration, the game start timing is random because it depends on the operation timing at which the player operates the start lever 41 to generate a start command. The game end timing is random because it depends on the end timing of the medal payout and the stop timing of all the reels 32L, 32M, 32R when no medal is paid out. As a result, the period during which the value of the first counter 111a is updated can be made random, and the number of updates of the first counter 111a updated during the period can be made random.

  Certainly, the first counter 111a may be constantly updated in the timer interrupt process, that is, the first counter 111a may be regularly updated. However, in such a configuration, for example, a bodily sensation device that transmits a signal with a period that is a natural number multiple of the period from when the value of the first counter 111a becomes a specific value to the specific value next is illegal. There is a concern that it may be used or an illegal board capable of outputting an illegal signal that causes the main controller 101 to erroneously recognize that a start command has been generated in a cycle that is a natural number multiple of the cycle may be attached. When these frauds are made, the delay time becomes constant for each game, and there is a concern that a winning random number may be obtained illegally.

  On the other hand, in a configuration in which the period during which the first counter 111a is updated is limited from the start to the end of the game, it is difficult to illegally obtain the winning random number. Is possible. The first counter 111a is updated based on the period from when the value of the first counter 111a reaches the predetermined value to the period when the first counter 111a reaches the predetermined value, and the period when the signal is output from the sensory device or the illegal board. This is because it can be shifted by an indefinite period.

  Furthermore, when the period during which the update of the first counter 111a is limited as described above, the period is fixed so that the number of updates of the first counter 111a performed during the period is a natural number multiple of 16 times. There is a possibility that fraud is assumed. However, since the period from the start to the end of the game varies depending on various factors, it is difficult to make it constant. Specifically, it changes depending on whether or not the result of the lottery process is winning. If it is off, the game ends without any medal payout, and if it is a win, the game ends after the medal payout, so the end timing of the game changes depending on whether or not the medal is paid out. is there.

  On the other hand, in the case of a slot machine, since the game progresses by operating the stop switch, there is a possibility that each stop switch may be operated at the same timing for each game so that the period is constant. However, it is difficult to make the period constant by operating the stop switches 42 to 44 at the same timing for each game. This is because the time until the reels stop changes depending on whether or not there is a win. As an example, if the left stop switch 42 is operated at the timing when the “replay” symbol of No. 7 on the left reel 32L reaches the lower stage, the left reel 32L will slide if the replay is won. If the cherries are won, the left reel 32L stops after sliding for one symbol. For this reason, it is impossible to specify the time required for all the reels 32L, 32M, 32R to stop unless the presence / absence of the winning combination and the type of winning combination can be grasped at least before the reels 32L, 32M, 32R are stopped. It is.

  Furthermore, even if it is possible to grasp the type of winning combination etc. at a stage before stopping each reel 32L, 32M, 32R, it is difficult to make the period constant. As described above, one symbol is composed of 24 offsets, and the rotation stop process is performed when the symbol offset value is 4 or less. For this reason, even when considering the phenomenon that the reel stops after sliding for one symbol, there may be a case where the reel actually stops after 20 offsets and a case where the reel stops after 24 offsets. Since it is difficult for human discrimination to recognize a difference of less than 4 offsets, it is possible to operate the stop switch every game at the timing when the symbol with the same symbol number has reached the predetermined position. This is because it is very difficult to operate the stop switch every game with the same symbol number and the same symbol offset timing.

  As a result, the randomness of the value of the first counter 111a can be ensured, and it becomes difficult to illegally acquire a random number that is won in the lottery.

  The period during which the value of the first counter 111a can be updated is from the start to the end of the game. With this configuration, the value of the first counter 111a used in the next game (that is, information that is the source of the delay time) can be prepared while the game is being played. It is possible to smoothly progress from one game to the next game while making it difficult to illegally acquire. Certainly, the period during which the value of the first counter 111a can be updated can be, for example, from the end of the game to the start of the next game. However, in such a configuration, there is a possibility that the time for making a round of the value of the first counter 111a cannot be secured, and it is necessary to take measures such as delaying the timing at which the next game can be started in order to secure the time. This is because it can occur.

  In the counter update process performed in the timer interrupt process, a period from when the reels 32L, 32M, and 32R start to rotate until a detection signal is input from the reel index sensor and after a start command or a stop command is generated. The periodical first counter in step S1403 includes the period until the operation of the corresponding switch (the start lever 41 or the stop switches 42 to 44) ends and the period after the medal payout starts to the end. In addition to updating 111a, the first counter 111a is further updated. In other words, the counter update process of the timer interrupt process has a configuration in which the first counter 111a is updated by 1 and there are cases in which two or more are updated depending on the progress of the game. With this configuration, the number of times the first counter 111a is updated in one counter update process can be made random. As a result, the number of times the first counter 111a is updated from the start to the end of the game can be made more random.

  The counter update process is performed in the timer interrupt process. With this configuration, it is possible to periodically start the counter update process while simplifying the program configuration.

  The system is configured to perform an interrupt wait process in a normal process that is started and repeated when the power is turned on, and the interrupt wait process ends when the value of the update counter 111c changes, that is, when a timer interrupt process is performed. The configuration. In the interrupt waiting process, when the game flag is set, the value of the first counter 111a is repeatedly updated until the value of the update counter 111c changes. With this configuration, the time from the start to the end of the interrupt wait process can be made random. While the timer interrupt process is periodically performed every 1.49 msec, the timing for starting the interrupt wait process, more specifically, the timing for acquiring the value of the update counter 111c in step S352 is from the power-on to the interrupt wait process. Varies depending on other processes performed up to. For this reason, if the interrupt wait process is started immediately after the end of the timer interrupt process, the update time of the first counter 111a can be secured by subtracting the time required for the timer interrupt process from 1.49 msec. While the counter 111a can be updated a plurality of times, if the timer interrupt process is performed immediately after step S352, only a time for updating the first counter 111a once can be secured. As a result, the number of updates of the first counter 111a performed in the interrupt waiting process can be made random, and the delay time from when the start command is generated until the CPU 102 outputs the latch signal can be made random. can do.

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

  In the normal process, when the interrupt waiting process is completed, a process for determining whether or not the start lever 41 (for example, step S518) or the like has been operated using the result of the sensor monitoring process of the timer interrupt process is performed. By adopting a configuration in which the determination process is performed after the end of the interrupt waiting process, it is possible to shorten the interval from the end of the timer interrupt process until the determination process is performed. In the configuration in which interrupt waiting processing is not performed, the interval is a time obtained by subtracting the time required for timer interrupt processing from 1.49 msec at the maximum, while in the configuration in which interrupt waiting processing is performed, the interval is from 1.49 msec at the maximum. The time required for the timer interrupt process is reduced, and the time required for performing the processes in steps S353 to S356 once and the time required for performing the negative determination in step S357 and performing the process in step S358 are reduced. Because it becomes. As a result, it is possible to make a determination related to the progress of the game, such as whether or not the start lever 41 has been operated, the game situation, and the like using the results of the sensor monitoring process made at a closer timing. Therefore, it is possible to reduce a time lag generated between the operation of the start lever 41 and the like performed by the player and the progress of the game and the like accompanying the operation. As a result, even when the count value of the random number generator 150 is latched after the delay time has elapsed since the start command is generated, the player is prevented from feeling uncomfortable with the time lag. It becomes possible.

  In addition to performing the interrupt waiting process before the operation determination process for determining whether or not the start lever 41 (for example, step S518) has been operated, the winning probability setting process steps S303 to S308 and the start waiting process start The configuration is such that it is performed in a looping process such as a preparatory process (steps S504 to S518). With this configuration, the slot machine 10 can be prevented from malfunctioning.

  Here, consider a configuration in which no interrupt wait processing is performed in the loop processing.

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

  In the process of determining whether or not the reset switch 72 has been operated in step S307, an all area reference process is performed. That is, referring to all the areas 112a to 112c of the reset detection area, it is determined that the reset switch 72 has been operated when “011” is stored, and the reset switch when “011” is not stored. 72 is determined not to be operated. In such a case, in the configuration in which the interrupt waiting process is not performed, there is a possibility that the determination process in step S307 is performed a plurality of times under the situation where “011” is stored. This is because the reset switch 72 is operated only once. In spite of this, the setting value is updated a plurality of times, leading to a malfunction.

  On the other hand, in the configuration in which the interrupt waiting process is performed before determining whether or not the reset switch 72 has been operated, the process of step S307 is performed in a situation where “011” is stored in the reset detection area. When the next processing of step S307 is performed, “110” or “111” is stored in the reset detection area, and it is avoided that affirmative determination is made that the reset switch 72 is operated in step S307. be able to. As a result, it is possible to avoid a malfunction in which the set value is updated a plurality of times in response to one operation of the reset switch 72, and it is possible to cause the game hall manager or the like to set the desired set value.

  Similarly, in the loop process of the pre-start preparation processes S504 to S518, it is determined in step S506 whether or not the credit insertion switches 56 to 58 have been operated. If it is determined that the credit insertion switches 56 to 58 have been operated, the credit insertion process is performed in step S510. . Even in such a loop process, in a configuration that does not perform the interrupt wait process, for example, when the timer interrupt process is performed immediately before the process of step S504, the loop process of steps S504 to S518 is performed until the next timer interrupt process is performed. It can be repeated several times.

  In the process of determining whether or not the credit insertion switches 56 to 58 in step S506 are operated, an all area reference process is performed. That is, referring to all areas 112a to 112c of each credit insertion detection area, if “011” is stored, it is determined that the corresponding credit insertion switch has been operated, and “011” is not stored. Is determined that the corresponding credit insertion switch has not been operated. In such a case, in the configuration in which the interrupt waiting process is not performed, there is a possibility that the determination process in step S506 is performed a plurality of times under the situation where “011” is stored, and the credit insertion switches 56 to 58 are operated only once. There is a possibility that it is determined that the operation has been performed a plurality of times even though the operation has not been performed. For example, this leads to a malfunction in which a plurality of virtual medals are inserted even though the third credit insertion switch 58 is operated to insert only one virtual medal.

  On the other hand, in the configuration in which the interrupt waiting process is performed at the stage before determining whether or not the credit insertion switches 56 to 58 are operated, the process of step S506 is performed in a situation where “011” is stored in the credit insertion detection area. When the next step S506 is performed, “110” or “111” is stored in the credit insertion detection area, and the credit insertion switches 56 to 58 are operated in step S506. It is possible to avoid making a positive determination repeatedly. As a result, it is possible to avoid a malfunction in which a virtual medal corresponding to a single operation of the credit insertion switches 56 to 58 is inserted a plurality of times, and to insert a virtual medal intended by the player. It becomes possible.

  The sensor information storage area 112 of the RAM 106 is composed of three storage areas, the first to third areas 112a to 112c. With such a configuration, it is possible to store a history of presence / absence of signal input from each detection sensor, and it is possible to determine whether an operation has been performed using the history of presence / absence of signal input. Further, the reset switch 72 and the credit insertion switches 56 to 58 are configured to perform all area reference processing, so that it is possible to preferably avoid malfunction of the slot machine 10. If the switches 56 to 58 and 72 are configured to perform one-area reference processing, step S307 in the loop processing of steps S303 to S308 of the winning probability setting processing and the steps in the loop processing of pre-start preparation processing S504 to S518. In S506, only the first area 112a of the corresponding detection area is referred to. As described above, the operation cycle of the CPU 102 is sufficiently faster than the time required from the start of the operation of the switches 56 to 58, 72 to the end thereof. Therefore, when one area reference processing is performed for the switches 56 to 58, 72, “1” is repeatedly stored in the first area 112a for a certain period even if interrupt waiting processing is performed. This is because there is a possibility that it is determined that the operation is performed a plurality of times for one operation.

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

  The value of the first counter 111a is not cleared even when the RAM is cleared. With this configuration, the random number generator 150 counts when a winning random number is generated after an illegal signal indicating RAM clear is input to the CPU 102 and the value of the first counter 111a is changed to an initial value. It is possible to prevent an illegal operation of the start lever 41 aiming at the value.

  The first counter 111a is provided in the RAM 106 built in the CPU 102, and the CPU 102 updates the first counter 111a. That is, the delay period is determined using the value of the soft free counter. With such a configuration, it is possible to make it difficult to fix the delay period to be constant. For example, the delay period can be determined using a count value generated by a hardware counter separate from the CPU 102. However, in such a configuration, there is a concern that the hardware counter may be changed to, for example, an illegal hardware counter that always outputs the same count value. If such a change is made, a winning random number is generated. This is because there is a possibility that the target period is targeted.

  When the count value latched by the hardware random number generator is used as it is as a random number as in the above embodiment, the following problems are concerned. That is, in the hardware random number generator, the oscillator outputs a clock signal to the counter at a fixed period, and the counter is updated based on the input of the clock signal. For this reason, for example, when the transmitter stops outputting a clock signal due to a failure or the like, the counter is not updated. Therefore, in the game after the clock signal is no longer output, the winning / failing determination is always performed using the same counter value, and there is a concern that the game place where the player or the slot machine is installed may suffer disadvantages. The

  Therefore, a monitoring circuit 152 composed of a D flip-flop circuit is provided in the main controller 101, and the start detection sensor 41a is connected to the D terminal of the monitoring circuit 152 and the second clock circuit 151 is connected to the CLK terminal. The CPU 102 was connected to the Q bar terminal. In such a configuration, when the second clock signal is not output from the second clock circuit 151 due to a failure or the like, or when the second clock signal remains output, the second monitoring circuit 152 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 102. Therefore, even if an operation signal is output from the start detection sensor 41a under these circumstances, the reels 32L, 32M, and 32R do not start rotating, and the game hall where the player or the slot machine 10 is installed is disadvantageous. It can be avoided. This is because if the second clock signal is not input to the random number generator 150 or remains input, the same random number is always used in a configuration in which a game can be performed thereafter.

  In this configuration, the reel 32L, 32M, 32R does not start rotating even if the start lever 41 is operated by the player or the manager of the game hall where the slot machine 10 is installed. It is possible to notify that an abnormality has occurred. Therefore, it becomes possible to quickly find out that an abnormality has occurred in the second clock circuit 151, and the game hall in which the player or the slot machine 10 is installed suffers disadvantages due to the abnormality of the second clock circuit 151. Can be suitably avoided.

  Certainly, a monitoring means for monitoring whether the second clock circuit 151 periodically outputs the second clock signal is provided, and if the second clock signal is not periodically output, the CPU 102 is abnormal. Even when the abnormality is processed such as notifying the player, it is possible to notify the player or the manager of the game hall that a certain abnormality has occurred in the second clock circuit 151. However, with such a configuration, it is necessary to store a program for performing processing at the time of occurrence of abnormality in the main control device 101 or the CPU 102 itself, and there is a concern about an increase in storage capacity. In addition, if any abnormality occurs in the monitoring means instead of the second clock circuit 151, the abnormality cannot be found despite the occurrence of the abnormality in the second clock circuit 151, 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 41a and the CPU 102 are connected via the monitoring circuit 152, each reel 32L, 32M, 32R does not start rotating despite the start lever 41 being 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 102 side. In addition, if any abnormality occurs in the monitoring circuit 152 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 the random number generator 150, the count value of the counter 150a is updated at a timing when the second clock signal switches from the no-input state to the input-present state, and the latch of the count value in the latch circuit 150b has the second clock signal input. The configuration is performed at the timing of switching from the state to the no-input state. 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.

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

  Furthermore, even if some abnormality occurs in the monitoring circuit 152 itself instead of the second clock circuit 151, the abnormality can be easily found. That is, when any abnormality occurs in the monitoring circuit 152, the output state of the start signal is constant regardless of the input state of the operation signal or the second clock signal. This is because the reels 32L, 32M, and 32R do not start rotating even though the player operates the start lever 41, or the start signal is output even though the player does not operate the start lever 41. It leads to the occurrence of an abnormal event such as 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 the failure of the second clock circuit 151 being unable to be detected due to an abnormality occurring in the monitoring circuit 152. It is possible to reduce the chance that the player or the game hall in which the slot machine 10 is installed suffers disadvantages.

  A first clock circuit 103 that inputs a clock signal to the CPU 102 and a second clock circuit 151 that inputs a clock signal to the random number generator 150 are provided separately, and the clock signals output from these clock circuits 103 and 151 are synchronized. Not configured. With this configuration, the timing at which the latch circuit 150b latches the count value in the random number generator 150 and the acquisition timing at which the CPU 102 acquires the random number from the latch circuit 150b are synchronized, and the CPU 102 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 command is not generated. That is, when the start command is generated while the reel is rotating, the stop command is invalidated. With such a configuration, when an abnormality occurs in the second clock circuit 151 while the second clock signal is still output, the abnormality can be quickly found. 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. In addition, when the abnormality occurs and the reels 32L, 32M, and 32R start to rotate under the condition where the start lever 41 is not operated, the stop switch 42 is used to end the game while feeling uncomfortable. The possibility of operating ~ 44 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.

  (1) In the above embodiment, the game flag is set when a start command is generated, and the update of the first counter 111a is permitted in the counter update process. However, this configuration is changed. For example, the game flag is set when the reels 32L, 32M, and 32R start to rotate. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said embodiment. Alternatively, the game flag is set when a predetermined number of medals are inserted (including insertion of virtual medals), such as when one medal is bet or when three medals are bet. To do. The bet on the medal means that the player has started preparations for starting the game, so even if such a configuration is adopted, it is expected to have the same effect as the above embodiment. it can.

  (2) In the above embodiment, the game flag is cleared when the medal payout is completed, and the update of the first counter 111a is prohibited in the counter update process. However, this configuration is changed. For example, the game flag is cleared when all the reels 32L, 32M, and 32R are stopped. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said embodiment.

  (3) In the counter update process of the timer interrupt process in the above embodiment, the value of the first counter 111a is updated between the start and end of the game. However, the present invention is limited to this configuration. Instead, the configuration may include a period in which the update process of the first counter 111a is permitted and a period in which the update process is prohibited.

  Here, it is desirable that the timing for permitting the update process is dependent on the player's operation. This is because the starting time can be made random. As the permission timing depending on the player's operation, in addition to the start command generation timing in the above embodiment, that is, the operation timing of the start lever 41 in a situation where the start command can be generated, for example, a medal is bet The operation timing of the stop switches 42 to 44 in a situation where a stop command can be generated, or the timing at which the stop command can be generated, can be considered.

  On the other hand, the timing for prohibiting the update process is desirably set to a timing at which the prohibition timing cannot be detected at least at the permission timing. Therefore, it is desirable that the timing for prohibiting the update process is a timing that does not depend on the player's operation, or a timing that is based on the player's operation but cannot be defined by the player. For example, in the case where the update process is permitted when the operation of the start lever 41 is started and the update process is prohibited when the operation is finished, the period of time during which the update process is performed by the player's intention is set. It can be set freely. For this reason, the value of the first counter 111a may be fixed. As a timing that does not depend on the player's operation, a timing for setting the slip table in the slip table setting process can be considered. Since such timing changes depending on the number of times that the winning combination is determined in step S605, the player cannot know the timing in advance, and the prohibition timing cannot be made constant. Further, as a timing based on the player's operation but not specified by the player, a stop timing of a predetermined reel such as the left reel 32L can be considered. Although such timing is based on the operation timing of the corresponding stop switch, since the number of slips is determined based on the sliding table, unless the player can grasp the winning combination in advance, the player will not know the timing in advance. It is not possible to make the prohibition timing constant.

  Therefore, a period during which the update process of the first counter 111a is permitted and a period during which the update process is prohibited may be set by appropriately combining the above-described permission timing and prohibition timing. For example, the timing at which the start command is generated is set as the permission timing, and the timing at which the slip table is set in the slip table setting process is set as the prohibit timing. Alternatively, the timing when the medals are bet is set as the permission timing, and the timing when the middle reel is stopped is set as the prohibition timing. Alternatively, the timing at which the stop command for the right reel is generated is set as the permission timing, and the timing at which all the reels are stopped is set as the prohibition timing.

  Needless to say, the permission timing and the prohibition timing are not limited to the establishment timing at which the above-described various conditions are satisfied, and may be timings based on the establishment of the above-described various conditions. For example, the permission timing may be a timing when a predetermined time has elapsed after the start command is generated, or the prohibition timing is a timing when the predetermined time has elapsed since the slip table was set in the slip table setting process. Also good.

  (4) In the counter update process of the timer interrupt process in the above embodiment, a period between the start of rotation of each reel 32L, 32M and 32R and the input of a detection signal from the reel index sensor, Step S1402 includes the period from when the stop command is generated until the operation of the corresponding switch (start lever 41 or stop switches 42 to 44) is completed, and the period from when the medal payout starts to the end. In addition to the periodic update of the first counter 111a, the first counter 111a is further updated. However, these configurations may not be provided. In such a configuration, the first counter is periodically updated in step S1402.

  Further, instead of or in addition to these configurations, the first counter 111a may be further updated when a specific condition is satisfied. For example, the first counter 111a is further updated while waiting until the wait time elapses, or the first counter 111a is further updated while waiting until a stop command is generated. You may do it.

  (5) In the counter update process of the timer interrupt process in the above embodiment, the first counter 111a is always allowed to be updated from the start to the end of the game, but the game starts. It is also possible to adopt a configuration in which permission and prohibition are repeatedly performed during the period from the start to the end. For example, the first counter 111a is allowed to be updated until one reel stops after the game is started, and the first counter 111a is stopped until one reel stops two reels. The updating of the first counter 111a is permitted until the two reels stop and all the reels stop.

  (6) In the above embodiment, the value of the first counter 111a is updated in the interrupt wait process of the normal process in addition to the counter update process of the timer interrupt process. It is good also as a structure which does not update the value of 111a. Further, the value of the first counter 111a may be updated in the interrupt waiting process only when the game flag is set. In such a configuration, in the normal process, the value of the first counter 111a is updated only in the interrupt wait process in the pre-stop process.

  (7) In the above embodiment, the first counter 111a is always prohibited from being updated until the next game is started after the game is finished. Also good. For example, after the power is turned on and the initialization process of the main process (step S201, see FIG. 13) is performed, the value of the first counter 111a is updated by 1 in the normal process, and the subsequent processes are performed. Alternatively, the value of the first counter 111a is updated by 1 in the loop processing of steps S303 to S308 of the winning probability setting processing. Alternatively, after the game information in the RAM is cleared (step S403, see FIG. 18), the value of the first counter 111a is updated by 1 in the normal processing, and the subsequent processing is performed.

  (8) In the above embodiment, when the start command is generated, the subtraction process is performed until the value of the first counter 111a becomes zero. However, the addition is performed until the value of the first counter 111a becomes zero. It is good also as a structure which performs a process. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said embodiment.

  (9) In the above embodiment, the process of subtracting until the value of the first counter 111a becomes 0 is performed by the timer interrupt process. However, the process may be performed by the normal process. Specifically, in the delay process of the normal process, a process of subtracting 1 from the value of the first counter 111a after setting the delay flag and then determining whether the value of the first counter 111a is 0 or not is performed. And When the value of the first counter 111a is not 0, the subtraction process is repeatedly performed until the value of the first counter 111a becomes 0. In such a configuration, the delay time can be shortened. When the subtraction process of the first counter 111a is performed in the timer interrupt process, the subtraction process can be performed only every 1.49 msec. However, the subtraction process of the first counter 111a is performed in the normal process. This is because the subtraction process can be performed about every 125 nsec.

  (10) In the above embodiment, when a start command is generated, the latch signal is output after the value of the first counter 111a becomes 0. However, the present invention is not limited to this configuration. The latch signal may be output after the value of the counter 111a becomes 1, or the latch signal may be output after the value of the first counter 111a becomes 10. That is, the latch signal may be output after the specific value unrelated to the value of the first counter 111a at that time is reached.

  (11) In the above embodiment, the first counter 111a is provided in the RAM 106 of the CPU 102 and the value of the first counter 111a is updated in the normal process and the timer interrupt process. The counter updated in the timer interrupt process may be provided separately.

  (12) In the counter update process of the timer interrupt process in the above embodiment, when the delay flag is set, the value of the first counter 111a is not updated. However, the value may be updated. In such a configuration, it is desirable that the value of the first counter 111a is subtracted by 2 or more in the delay counter process.

  (13) In the above embodiment, the configuration having only the random number generator 150, which is a hardware counter, as a counter for generating a random number has been described. However, the present invention is not limited to this configuration.

  For example, in addition to the random number generator 150, a soft free counter is provided in the RAM 106 of the CPU 102. Then, a random number is created by performing a predetermined calculation (for example, addition) using the count value of the soft free counter and the count value of the random number generator 150. In other words, the random number is generated using the basic random number generated by the software free counter and the basic random number generated by the hardware counter. In such a configuration, even if the random number generator 150 is changed to, for example, an illegal hardware random number generator that outputs a count value for BB winning, the count value of the hardware random number generator and the soft free counter It is possible to change to a random number that does not win BB by creating a random number using the count value of BB. Therefore, it is possible to make it difficult for the winning random numbers to be obtained illegally.

  Alternatively, the hardware counter is not provided, and the count value of the soft free counter provided in the RAM 106 of the CPU 102 is used as a random number. At this time, one soft free counter may be provided and the count value of the soft free counter may be used as a random number, or a plurality of soft free counters may be provided and a random number may be generated using the basic random numbers generated by these soft free counters. It is good also as composition to do.

  (14) The counter update process of the timer interrupt process in the above embodiment may be configured as a normal process.

  (15) In the above-described embodiment, the value of the first counter 111a is not cleared (initialized) even when the RAM is cleared, but may be cleared.

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

  (17) In the above embodiment, an update process for adding or subtracting 1 from the value of the first counter 111a is performed. However, an update process for adding or subtracting two or more values may be performed. Needless to say.

  (18) The latch circuit 150b of the random number generator 150 and the CPU 102 may be 16-bit inverted connection.

  (19) In the above embodiment, the counter 150a of the random number generator 150 is configured with 16 bits and the first counter 111a is configured with 4 bits. However, the number of bits to be configured is arbitrary. However, when the number of bits of the first counter 111a is increased, the delay time is increased accordingly. Therefore, in such a case, it is desirable to devise such as increasing the number of places where the first counter 111a is subtracted in the timer interrupt process.

  (20) The random number generator 150 in the above embodiment latches the count value at the timing when the latch signal from the CPU 102 is input, and outputs the latched count value to the CPU 102, but this configuration is changed. . For example, the random number generator 150 is configured to always output the count value of the counter 150a via the latch circuit 150b. That is, the CPU 102 is configured to always receive the count value of the counter 150a. When the delay time elapses, the CPU 102 latches the count value of the counter 150a input to the CPU 102 at that time, and acquires it as a random number. Even if it is a case where it is set as this structure, it is clear that there exists an effect similar to the said embodiment.

  (21) In the above embodiment, the monitoring circuit 152 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.

  (22) In the above embodiment, the Q bar terminal of the monitoring circuit 152 is connected to the CPU 102, and the L level output signal output from the Q bar terminal is recognized as the start signal by the CPU 102. Even when the CPU 102 is connected via an inverter, it is apparent that the same effects as those of the above-described embodiment can be obtained. Further, if the CPU 102 recognizes an H level output signal as a start signal, the Q terminal and the CPU 102 may be connected, or the Q bar terminal and the CPU 102 may be connected via an inverter. .

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

  (24) In the above embodiment, the monitoring circuit 152 constituted by the D flip-flop circuit is provided to prevent the player or the playground from being disadvantaged when any abnormality occurs in the second clock circuit 151. The configuration is changed, but the configuration is changed.

  A watchdog timer that constantly monitors whether the second clock circuit 151 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 41a and the input signal from the watchdog timer is provided. Then, an inverted signal obtained by inverting an output signal from the AND circuit by an inverter is input to the CPU 102.

  In this case, if the second clock circuit 151 periodically outputs the second clock signal, the timer value is set repeatedly 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 41a. When an operation signal is output, the output signal is inverted by an inverter and input to the CPU 102 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 151, 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 or not the operation signal is input. Therefore, even if the start lever 41 is operated and an operation signal is output, no start signal is output from the AND circuit to the CPU 102. As a result, a situation occurs in which the reels 32L, 32M, and 32R do not start rotating even though the start lever 41 is operated, and it is confirmed that some abnormality has occurred inside the slot machine 10 or 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 151. 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 151, the duty ratio is 0% (in the case of constant or high impedance at 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 41 is operated and an operation signal is output, no start signal is output from the AND circuit to the CPU 102.

  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%.

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

  The latch circuit 150b is configured to latch after appropriately replacing the bit arrangement of the count value of the counter 150a.

  As an example of such a configuration, a configuration in which the latch circuit 150b latches a bit arrangement from the lowest order to the highest order of the count value of the counter 150a in the reverse direction can be given. In such a configuration, the value latched by the latch circuit 150b changes irregularly with respect to the input of the second clock signal, and it is possible to avoid a problem that a predetermined random number is intentionally acquired by the player. .

  In addition, the bit arrangement of the values latched by the latch circuit 150b may be changed as appropriate and output to the CPU 102. Even in such a configuration, the random number input to the CPU 102 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 of different frequencies are provided, and the count value of the counter 150a is updated based on these clock signals.

  In this case, a selection circuit 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 152. In such a configuration, the cycle in which the count value of the counter 150a 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 in which a predetermined random number is intentionally acquired by the player.

  Instead of the counter 150a, 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 150b changes in a complicated manner based on the change in the input state of the second clock signal, so that it is possible to avoid the problem that a predetermined random number is intentionally acquired by the player. it can.

  (26) In the above embodiment, the second clock circuit 151 for random numbers is provided as a clock source for the hardware random number generator 150 in addition to the first clock circuit 103 for the CPU 102. It may be used as a clock source. At this time, the clock signal of the first clock circuit 103 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 150 does not fluctuate due to an abnormality in a circuit unit that performs frequency modulation, a problem arises that the random number is always constant. By obtaining the same effect as the form, the abnormality can be discovered.

  (27) In the above embodiment, the second clock signal is input to the random number generator 150 and the monitoring circuit 152 without modulating the frequency of the second clock signal output from the second clock circuit 151. However, a configuration 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 151, and the converter may be connected to the random number generator 150 and the monitoring circuit 152.

  (28) In the above embodiment, the inserted medal detection sensor 45a is configured by the three sensors, the first to third sensors, but is not limited to such a configuration, and may be configured by only one sensor. And you may comprise by two sensors or four or more sensors. In the above embodiment, the time from the first sensor to the second sensor and the order in which the second sensor and the third sensor are turned on / off are monitored. good. That is, the inserted medal detection sensor may be configured by two sensors, the first sensor and the second sensor, and only the time from the first sensor to the second sensor may be monitored. The first sensor and the second sensor are turned on / off. It is good also as a structure which monitors only the order performed.

  (29) In the above embodiment, it is determined whether or not a start command is issued after three medals are bet. However, the start command is also issued after one bet or two bets. It goes without saying that it may be configured to determine whether or not it has occurred. In such a configuration, the slot waiting process is performed immediately before the process of determining whether or not the credit insertion switch has been operated as in the above-described embodiment (step S506, see FIG. 19). It is possible to more suitably avoid the malfunction of. This is because there is a chance that the game cannot be started with the number of bets desired by the player.

  (30) In the above embodiment, as a privilege to be granted, a bonus is provided in which a medal is paid out in addition to a bonus that a game state shifts and a bonus of replaying, but the bonus is limited to this configuration. Instead, any configuration may be used as long as the player is given some kind of privilege. For example, a configuration in which a prize other than a medal is paid out instead of a medal to pay out a medal may be used. Further, in a slot machine that does not have an actual medal insertion or medal payout function and manages credits owned by a player, an increase in credited medals corresponds to provision of a privilege.

  (31) In the above embodiment, a slot machine having three reels arranged in parallel and having five lines as effective lines has been described. However, the present invention is not limited to this configuration. For example, five reels arranged in parallel It may be a slot machine provided or a slot machine having seven effective lines.

  (32) In the above embodiment, the so-called A type slot machine has been described. However, a B type, a C type, a combined type of A type and C type, a combined type of B type and C type, and further a CT game are provided. The present invention may be applied to any slot machine, such as the above-mentioned type, and it is obvious that the same effects as those of the above-described embodiment can be obtained in any case. In addition, examples of bonus winning in each type include BB winning, RB winning, SB winning, CT winning and the like.

  (33) In the above-described embodiment, an example in which the slot machine 10 is embodied has been shown, but the present invention may be applied to a pachinko machine. Further, the present invention may 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.

  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 gaming machine main body is provided with a gaming board in which a gaming area as a gaming ball flying area is formed and an operating port and a liquid crystal display device are installed, and the gaming area and liquid crystal are provided by a visual window provided on the door member. The display device is visible. Then, as the game ball launched by the game ball launching device wins the operating opening, 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.

  Also in the pachinko machine, the time from the start of the change display of the pattern to the end changes depending on the result of the internal lottery. This is because it changes depending on the presence or absence of reach variation, the combination of the patterns to be displayed in the final stop, and the like. For this reason, even in the pachinko machine, for example, when the game ball wins the operation opening, the update process of the first counter 111a is permitted, and the value of the first counter 111a is prohibited when the variation display of the pattern is finished. If it does so, it can be anticipated that there exists an effect similar to the said embodiment.
