  Hereinafter, an embodiment in which the present invention is applied to a slot machine which is a kind of gaming machine will be described in detail with reference to the drawings. FIG. 1 is a front view of the slot machine 10, and FIG. 2 is a perspective view of the slot machine 10 with the front door 12 opened.

  As shown in FIG. 2, the slot machine 10 includes a housing 11 that forms an outer shell thereof. The casing 11 is formed in a box shape with the front surface opened as a whole by fixing a plurality of wooden panels.

  A front door 12 is attached to the front side of the housing 11. The front door 12 is supported by the housing 11 so that the inner space of the housing 11 can be opened and closed with the left side portion as a rotation axis. Note that the front door 12 is locked so as not to be opened by a locking device 13 provided on the rear surface thereof, and this locked state is released by an unlocking operation with a predetermined key on the key cylinder 14.

  As shown in FIG. 1, a game panel 20 for notifying the player of the game state is provided on the upper side of the central portion of the front door 12. The gaming panel 20 is formed with three vertically long display windows 21L, 21M, and 21R arranged side by side. The display window portions 21L, 21M, and 21R are made of a transparent or translucent material, and the inside of the slot machine 10 is visible through the display window portions 21L, 21M, and 21R.

  As shown in FIG. 2, the inside of the housing 11 is divided into upper and lower parts by a partition plate, and a reel unit 31 is attached to the upper part of the partition plate. The reel unit 31 includes a left reel 32L, a middle reel 32M, and a right reel 32R each formed in a cylindrical 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 arranged on the same axis extending in the substantially horizontal direction, and the reels 32L, 32M, and 32R correspond to the display window portions 21L, 21M, and 21R on a one-to-one basis. Yes. Therefore, a part of the surface of each reel 32L, 32M, 32R can be visually recognized through the corresponding display window 21L, 21M, 21R. 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 21L, 21M, and 21R.

  Each of the reels 32L, 32M, and 32R is connected to a stepping motor 33, and each reel 32L, 32M, and 32R can be individually rotated, that is, independently driven by the stepping motor 33. It has become. Since these reels 32L, 32M, and 32R have the same configuration, the left reel 32L will be described as an example here with reference to FIG. FIG. 3 is an assembled perspective view of the left reel 32L.

  The left reel 32L includes a cylindrical skeleton member 41 that forms a cylindrical cage, and a belt-like belt (not shown in FIG. 3) wound endlessly on the outer peripheral surface thereof. And it is affixed on the cylindrical frame | skeleton member 41 through a pair of seal part formed along the long side both sides of the belt so that the wound state may be maintained. A large number of symbols as identification information are printed at equal intervals on the outer peripheral surface of the belt. A boss portion 42 is formed at the center of the cylindrical skeleton member 41, and is attached to the drive shaft of the stepping motor 33 via a disk-like boss reinforcing plate 43. Accordingly, when the drive shaft of the stepping motor 33 is rotated, the cylindrical skeleton member 41 is rotated around the drive shaft, and the left reel 32L is rotated.

  The stepping motor 33 is fixed by screws 45 to the side surface of the motor plate 44 arranged in an upright state in the reel unit 31. The motor plate 44 is provided with a reel index sensor 46 in which a light emitting element 46a and a light receiving element 46b are held at a predetermined interval. On the other hand, a base end portion 47b of a sensor cut bun 47 extending in the radial direction is fixed to the boss reinforcing plate 43 integrated with the left reel 32L with a screw 48. The tip 47a of the sensor cut bun 47 is bent at a substantially right angle and is positioned so that it can pass between the elements 46a and 46b of the reel index sensor 46. Each time the left reel 32L makes one rotation, the reel index sensor 46 detects the passage of the tip 47a of the sensor cut bun 47, and a detection signal is output to the main controller 70 described later each time the detection is made. Therefore, main controller 70 can confirm and correct the angular position of left reel 32L for each rotation based on this detection signal.

  For example, the stepping motor 33 is set to rotate once by applying an excitation signal of 504 pulses, and the rotation position of the stepping motor 33, that is, the rotation position of the left reel 32L is controlled by this excitation signal.

  On each belt of each of the reels 32L, 32M, and 32R, a plurality of, specifically, 21 symbols are drawn in the long side direction (circumferential direction). Therefore, 24 pulses (= 504 pulses / 21 symbols) are required to switch from one symbol to the next symbol at a predetermined position. Based on the number of pulses from when the detection signal of the reel index sensor 46 is output, it is recognized which symbols are visible from the display window portion 21L, or arbitrary symbols are displayed from the display window portion 21L. It is possible to perform control to make the state visible.

When the “replay” symbol on the left reel 32L, the “watermelon” symbol on the middle reel 32M, and the “red 7” symbol on the right reel 32R stop on the active line, one medal will be paid out as the fourth watermelon prize. Done. When the “bell” symbol of each reel 32L, 32M, 32R stops on the active line, eight medals are paid out as a bell winning.

  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 may be stopped on the active line for the middle reel 32M and the right reel 32R. When the “cherry” symbol stops at the position where the plurality of active lines on the left reel 32L overlap (specifically, the upper stage or the lower stage), a cherry win is established on each active line, and the overlapping active lines The medal payout is made by the number multiplied. Specifically, four medals are paid out in this embodiment. On the other hand, when the “cherry” symbol is stopped at a position (specifically, in the middle stage) where only one active line exists in the left reel 32L, medals are paid out for the amount set as the cherry winning. Specifically, in this embodiment, two medals are paid out.

  As state transition winnings in which only the game state transition is performed, there are a first BB winning, a second BB winning, and a third BB winning. When the “red 7” symbol of each reel 32L, 32M, 32R stops on the active line, the first BB wins, and when the “white 7” symbol of each reel 32L, 32M, 32R stops on the active line. Becomes the second BB prize and becomes the third BB prize when the "BAR" symbol of each reel 32L, 32M, 32R stops on the active line. When these BB winnings are established, the gaming state shifts to the BB state.

  There is a re-game winning as a winning that is given a re-playing privilege that allows the player to play the next game without inserting a medal. When the “replay” symbols of the reels 32L, 32M, and 32R are stopped on the active line, a re-game win is awarded. When the re-game winning is established, the medal payout and the state transition are not performed, but the player can play the next game without reducing the medals owned and without inserting medals.

<Processing executed by MPU 72 of main controller 70>
Next, processing executed by the MPU 72 of the main controller 70 will be described. The processing of the MPU 72 is roughly divided into normal processing that is repeatedly executed after execution of the main processing that is started when the power is turned on, and timer interrupt processing that is started by periodically interrupting the normal processing. For convenience of explanation, timer interrupt processing will be described first, followed by normal processing.

<Timer interrupt processing>
FIG. 8 is a flowchart showing timer interrupt processing. The timer interruption process is started every 1.49 msec, for example.

  In the register saving process shown in step S101, the values of all the registers in the MPU 72 used in the normal process described later are saved in the RAM 74. In step S102, it is confirmed whether or not “1” is set in the power failure flag. If “1” is set in the power failure flag, the process proceeds to step S103, and processing at power failure is executed.

  The power failure flag is set when a power failure signal from the power failure monitoring circuit of the power supply device 65 is input to the MPU 72. In power failure processing, it is first determined whether the transmission of commands other than the power failure command has been completed. If transmission has not been completed, this processing is terminated and the processing returns to timer interrupt processing. End transmission of. If transmission of a command other than the power failure command has been completed, transmission of the power failure command is started, and this timer interrupt processing is repeatedly executed until transmission of the power failure command is completed. When transmission of the power failure command is completed, the value of the stack pointer of the MPU 72 is stored in the RAM 74. Thereafter, the output state of the output port of the MPU 72 is cleared, and all actuators (not shown) are turned off. Then, a determination value for determining whether or not the data in the RAM 74 is normal when the power failure is resolved is stored in the RAM 74, thereby prohibiting subsequent RAM access. 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.

  When 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 end-of-interrupt declaration process is performed to enable the next timer interrupt to be set for the MPU 72 itself. In step S106, in order to rotate and stop each reel 32L, 32M, 32R, a stepping motor control process for driving each stepping motor 33 is performed. In step S107, the state of various sensors connected to the input port is read, and sensor monitoring processing for monitoring whether the read result is normal is performed. In step S108, timer calculation processing for subtracting the value of each counter or timer is performed. In step S109, a counter process is performed to output the result of counting the number of medals bet and the number of payouts to the outside.

  In step S110, command output processing for transmitting various commands to the sub-control device 80 is performed. In step S111, port output processing for outputting data corresponding to the I / O device from the input / output port is performed. In step S112, the value of each register saved in the RAM 74 in the previous step S101 is restored to the corresponding register in the MPU 72. Thereafter, in step S113, an interrupt permission process for permitting the next timer interrupt is performed, and this series of timer interrupt processes is terminated.

<Normal processing>
Next, normal processing will be described based on the flowchart of FIG.

  In step S201, an interrupt permission process for permitting the next timer interrupt is performed. In step S202, pre-start processing for enabling a game is performed. In the pre-start process, the process waits until the sub-control device 80 and the like finish initialization. When the initialization of the sub-control device 80 and the like is completed, the game management process shown in steps S203 to S212 is performed.

  As the game management process, in step S203, data such as various game information stored in the RAM 74 is cleared. In this case, a process for initializing each area of the RAM 74 used in one game is executed. Thereafter, in step S204, start waiting processing is performed.

  In the start waiting process, it is determined whether or not a re-game winning is established in the previous game. If a re-game winning is established, an automatic insertion process for automatically inserting the same number of virtual medals as the previous bet is performed, and the start waiting process is terminated. When a re-game winning is established in the previous game, the player can play this game without reducing the number of medals owned and without inserting medals. If no re-game winnings have been established, it is determined whether or not the settlement button 60 has been operated. If the settlement button 60 has been operated, the same number of medals as the credited virtual medals are paid out. Perform the medal return process. After completion of the medal return process or when the settlement button 60 is not operated, whether or not the medal insertion or credit insertion buttons 57 to 59 are operated between the previous start wait process and the current start wait process If either one is performed, a medal insertion process for changing the number of bets or the like is performed, and the start waiting process is terminated. If neither the medal insertion nor the operation of the credit insertion buttons 57 to 59 is performed between the previous start waiting process and the current start waiting process, the start waiting process is ended as it is.

  After the start waiting process is completed, it is determined in step S205 whether or not the bet number of medals has reached a specified number (3 in the present embodiment). If the bet number has not reached the specified number, the process proceeds to step S204. Return to the start wait process. If the bet number has reached the specified number, it is determined in step S206 whether or not the start lever 51 has been operated. When the start lever 51 is not operated, the process returns to the start waiting process in step S204.

  On the other hand, when the start lever 51 is operated, it means that a start command has been generated to start the game. In such a case, an effective line setting process for setting all the combination lines of the first line ML1 to the fifth line ML5 described above in step S207 as effective lines is performed, and the selector 61 is controlled in step S208. Bet reception is prohibited. Thereafter, the lottery process in step S209, the reel control process in step S210, the medal payout process in step S211 and the BB state process in step S212 are executed in order, and the process returns to step S203.

  Of the processes in steps S209 to S212, the medal payout process in step S211 and the BB state process in step S212 will be described first.

  In the medal payout process in step S211, it is determined whether or not the payout number set in the payout information storage area is “0”. When the number of payouts is “0”, it means that it is determined in the previous payout determination process that a small winning combination has not been established. In such a case, based on the winning combination set set in the payout determination process, it is determined whether or not a re-game winning is achieved. If the re-game winning is not established, the medal payout process is terminated as it is, and if the re-game winning is established, the re-game setting process is performed to change the gaming state to the re-gaming state, and the medal payout process is performed. finish. In the start waiting process described above (step S204), the automatic insertion process is performed when it is determined that the current gaming state is the re-gaming state.

  On the other hand, when the number of payouts set in the payout information storage area is not “0”, the same number of medals are paid out, and the medal payout process is ended. Specifically, regarding the payout of medals, when the count value of the credit counter does not reach the upper limit (the number of stored medals is 50), the payout number is added to the count value of the credit counter. When the count value of the credit counter reaches the upper limit, or when the count value reaches the upper limit during the addition of the number of payouts, the medal payout rotating plate is driven and the medal is received from the hopper device 64 by the medal tray. Pay out to 18. When the current gaming state is the BB state, a process of subtracting the payout number from the value of the remaining payout number data described later is performed.

  In the BB state process of step S212, it is determined whether or not a winning corresponding to the winning data is established in a situation where the first BB winning data, the second BB winning data, or the third BB winning data is set. If any BB winning is established, the gaming state is shifted to the BB state by setting a BB setting flag in the RAM 74. At this time, “442” is set in the RAM 74 as remaining payout number data indicating the number of remaining medals that can be paid out during the BB state.

  When the gaming state becomes the BB state, a lottery table for a BB state is selected in a lottery process described later. In the BB state, every time the reels 32L, 32M, and 32R stop rotating and a winning occurs, the number of winnings is subtracted from the remaining payout number data in the RAM 74. When the remaining payout number data becomes “0”, the BB setting flag is cleared, and the BB state ends.

<Lottery processing>
Next, the lottery process of step S209 in the normal process (FIG. 9) will be described with reference to the flowchart of FIG.

  In step S301, a random number used when determining whether or not the combination is correct is acquired. The slot machine 10 is configured such that when the start lever 51 is operated, the hardware circuit latches the value of the free-run counter at that time. The free-run counter generates random numbers from 0 to 65535, and the MPU 72 stores the value latched by the hardware circuit in the RAM 74 after confirming the operation of the start lever 51. With such a configuration, it is possible to quickly acquire a random number at the timing when the start lever 51 is operated, and it is possible to avoid the occurrence of problems such as synchronization. The hardware circuit of the slot machine 10 is configured to latch the value of the free run counter each time the start lever 51 is operated.

  After acquiring the random number, in step S302, a lottery table for determining whether or not the winning combination is selected is selected. The slot machine 10 is roughly divided into two types of game states, a normal game state and a BB state. In step S302, the current gaming state of the slot machine 10 is determined based on the contents of the gaming state flag provided in the RAM 74, and a lottery table corresponding to the gaming state is selected.

  For example, when the current gaming state is the normal gaming state, the normal gaming state lottery table is selected. In this case, the present slot machine 10 is prepared in advance with six stages of winning probabilities from “Setting 1” to “Setting 6”. The setting key is inserted into the setting key insertion hole 68 and turned ON, and a predetermined probability is set. By performing the operation, it is possible to set which winning probability is used to execute the internal processing in the normal gaming state. In step S302, the lottery table with the lowest expected value of medal payout is selected when the setting state is “setting 1”, and the lottery table with the highest expected value of medal payout is selected when it is “setting 6”. On the other hand, in the BB state, the winning probability is common to “setting 1” to “setting 6”.

  Note that the configuration regarding the winning probability is not limited to the above, and at least some of the winning combinations may be common without depending on the set value in the normal gaming state. For example, the winning probability for the special gaming state such as the BB state is different from “setting 1” to “setting 6”, while the winning probability for some or all of the other roles (small role, replaying role) is a set value. It is good also as a structure which is common without depending on. In addition, the winning probabilities of a predetermined small combination or all small combinations in the BB state may be different from “setting 1” to “setting 6”.

  The lottery table will be described with reference to FIG. FIG. 11A is a lottery table for the normal gaming state selected in the normal gaming state of “Setting 3”, and FIG. 11B is a lottery table for the BB state selected in the BB state. . As shown in FIGS. 11A and 11B, an index value IV is set in the lottery table, and each index value IV is uniquely associated with a winning combination. Point value PV is set.

  For details of the lottery table for the normal gaming state, as shown in FIG. 11A, IV = 1 to 3 and 12 to 18, respectively, the first BB role, the second BB role, the third BB role, the cherry role, One lottery role is set among the first watermelon role, the second watermelon role, the third watermelon role, the fourth watermelon role, the bell role, and the replaying role. Is different.

  On the other hand, a plurality of lottery combinations are set for IV = 4 to 11. For example, when IV = 4, three types of lottery roles are set as the second watermelon role, cherry role, and first BB role as the lottery role. Any one of the three winning combinations or a simultaneous winning in a predetermined combination of these three types of combinations occurs. The three types of lottery combinations are set in this way as well when IV = 5 and IV = 6. However, in the case of IV = 4 to 6, the combination of lottery combinations set is different.

  In addition, when IV = 7, two types of lottery roles, a cherry role and a second BB role, are set as a lottery role, and when winning is selected when IV = 7, any one of these two types of roles is set. Only, or simultaneous winning of these two types of roles occurs. The two types of lottery combinations are set as described above even when IV = 8 to 11. However, in IV = 7 to 11, the combination of lottery combinations set is different.

  In the above 10 types of lottery winning combinations, the winning probabilities including both the case of single winning and the case of overlapping winning are bell role> replaying role> cherry role> second watermelon role> first watermelon role = third Watermelon role = fourth watermelon role> first BB role = second BB role = third BB role. That is, the winning probability of each BB combination is set to be the lowest. In this case, there is a case where each BB combination is won by one lottery process and a case where both BB combinations are won simultaneously with other predetermined combinations in one lottery process. Thereby, for example, even when the winning of the predetermined combination is established, the player can be expected to win the BB combination. On the other hand, since the BB combination may be won by itself, it is possible to make the player expect the BB combination to be won even in a situation where no winning is achieved.

  In detail regarding the lottery table for the BB state, as shown in FIG. 11B, IV = 11 to 17 are set as IV = 1 to 7 in the lottery table for the normal gaming state. In each of the index values, only a small combination is set as a lottery combination. That is, in the BB state, the first BB combination to the third BB combination and the replay combination are not set as the lottery combination.

  In the BB state, the winning combination probability of the small role is set higher than that in the normal gaming state. Also, in the case of IV = 2 to 7, one of the lottery roles of the cherry role, the first watermelon role, the second watermelon role, the third watermelon role, the fourth watermelon role, and the bell role is set. On the other hand, at IV = 1, the second watermelon combination and the cherry combination are set as the lottery combination. The winning probability is set so that the bell role is the highest, the simultaneous winning of the second watermelon role and the cherry role is the next highest, and the individual winnings of the cherry role and the first to fourth watermelon roles are the lowest. Yes.

  Returning to the description of the lottery process (FIG. 10), after selecting the lottery table, the index value IV is set to 1 in step S303, and in the subsequent step S304, a determination value DV used for determining whether or not the winning combination is set. 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 acquired in step S301 is set as the current determination value DV, and a new point value PV corresponding to 1 as the current index value IV is added to the random value. The determination value is DV.

  Thereafter, in step S305, 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 S306, and the winning combination data corresponding to the index value IV at that time is set in the RAM 74. For example, when the determination value DV exceeds 65535 when IV = 4, in step S306, data indicating that the second watermelon role, the cherry role, and the first BB role are won is set in the RAM 74, and IV = 12 If the determination value DV exceeds 65535, data indicating that the cherry role has been won is set in the RAM 74 in step S306.

  By the way, winning data indicating that the set winning data has won the first BB (hereinafter referred to as “first BB winning data”), winning data indicating that the second BB has been won (hereinafter referred to as “second BB winning”). If it is not winning data indicating that the third BB has been won (hereinafter referred to as “third BB winning data”), the data indicating that the winning is set in the RAM 74 is the corresponding selection data. Is reset after the game in which is set (see step S203 of the normal process).

  On the other hand, when the winning data is the first BB winning data, the second BB winning data, or the third BB winning data, the winning data is reset as one of the conditions that the corresponding BB winning is established. That is, the first BB winning data, the second BB winning data, and the third BB winning data may be valid over a plurality of games.

  In step S306 when the first BB winning data, the second BB winning data, or the third BB winning data is carried over in the normal gaming state, if the current index value IV is 1 to 3, the corresponding winning data is not set. Yes, if the current index value IV is 4 to 10, the winning data other than the BB winning data is set. If the current index value is other than 1 to 10, the winning data corresponding to the index value IV is set. To do. That is, in a game in which the first BB winning data, the second BB winning data, or the third BB winning data is carried over, the corresponding winning data is set when winning a role other than the first BB role, the second BB role, and the third BB role. On the other hand, if the first BB combination, the second BB combination or the third BB combination is won, the corresponding winning data is not set.

  If the determination value DV does not exceed 65535 in step S305, 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 S307, and in the subsequent step S308, 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 S304 and the determination of whether or not the winning combination is continued. At this time, in step S304, a 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 S305, whether or not a winning combination is made is determined based on the determination value DV.

  After the winning data is set in step S306, or when it is determined in step S308 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 S309. The lottery result command is a command transmitted to the sub-control device 80 in order to grasp the result of the winning / failing determination of the combination, and the lottery result command includes data corresponding to the determination result of the winning / rejecting combination. Thereafter, in step S310, stop information first setting processing for setting stop information for reel stop control is performed, and the lottery processing is terminated.

<Reel control processing>
Next, the reel control process of step S210 in the normal process (FIG. 9) will be described based on the flowchart of FIG.

  In the reel control process, first, in step S401, a rotation start process for starting the rotation of each reel 32L, 32M, 32R is performed. In the rotation start process, it is checked whether or not a predetermined wait time (for example, 4.1 seconds) has elapsed since the reel started to rotate in the previous game. Wait until When the wait time has elapsed, a wait time for the next game is reset, and a motor control initialization process for setting rotation start information in the motor control storage area provided in the RAM 74 is performed. By performing such processing, stepping motor acceleration processing is started in the stepping motor control processing in step S106 in the timer interruption processing (FIG. 8), and the reels 32L, 32M, and 32R start to rotate. Thereafter, the process waits until the reels 32L, 32M, and 32R rotate at a constant rotation speed at a predetermined rotation speed, and the rotation start process ends. In addition, when the rotational speed of each reel 32L, 32M, 32R reaches a constant speed, the MPU 72 can issue a stop command by lighting up a lamp (not shown) of each stop button 52-54. Is notified to a player or the like.

  Following the rotation start process, in step S402, it is determined whether any of the stop buttons 52 to 54 has been operated. When none of the stop buttons 52 to 54 is operated, the process waits until any of the stop buttons 52 to 54 is operated. If it is determined that any of the stop buttons 52 to 54 has been operated, the process proceeds to step S403, whether or not the stop buttons 52 to 54 corresponding to the rotating reels have been operated, that is, whether or not a stop command has been issued. Determine whether. If no stop command has been issued, the process returns to step S402 and waits until any of the stop buttons 52 to 54 is operated. If a stop command is generated, a stop command command is set in step S404.

  The stop command command is a command transmitted to the sub-control device 80 in order to grasp which stop button 52 to 54 is operated to generate a stop command. When the stop command command is set, stop control processing shown in steps S405 to S411 is performed to stop the rotating reel.

  In step S405, the symbol number of the reaching symbol that has reached the base point position (lower in this embodiment) at the timing when the stop buttons 52 to 54 are operated is confirmed. Specifically, the symbol number of the reaching symbol reaching the base point position is confirmed by the number of excitation pulses output from the time when the detection signal of the reel index sensor 46 is input. In subsequent step S406, the number of reels to be stopped this time is calculated based on the stop information stored in the RAM 74.

  In the slot machine 10, as a stop mode for stopping the reels 32L, 32M, 32R, a stop mode for stopping the reaching symbol reaching the base point position when the stop buttons 52 to 54 are operated 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. Therefore, in step S406, based on the stop information stored in the RAM 74, one of 0 to 4 is calculated as the number of slips.

  Thereafter, in step S407, the calculated number of threads is added to the symbol number of the reaching symbol, and the symbol number of the stop symbol that is actually stopped at the base point position is determined. In step S408, a standby process for stopping is executed to wait until the determined stop symbol is stopped at the base position. By executing the process of step S407, in the stepping motor control process of step S106 in the timer interrupt process (FIG. 8), the stop symbol is placed at the base position for the stop command target reel among the reels 32L, 32M, 32R. The stop control is performed so that is stopped. Specific contents of the stop control will be described later.

  When the stop control of the stop command target reel is completed, the process proceeds to step S409. In step S409, it is determined whether or not all reels 32L, 32M, and 32R are stopped. If all the reels 32L, 32M, 32R are not stopped, stop information second setting processing is performed in step S410, and the process returns to step S402.

  Here, the stop information is information for making the stop mode of each reel 32L, 32M, 32R correspond to the result of the lottery process (FIG. 10). By using the stop information, When the stop buttons 52 to 54 are stopped, it is possible to calculate the number of slips (specifically “0” to “4”) for the reaching symbol that has reached the base point position. As the stop information, slip number data indicating the correspondence between each symbol and the number of slips is stored in advance in the ROM 73 in correspondence with the lottery results and the stop order of the reels 32L, 32M, and 32R. However, the present invention is not limited to this, and a configuration may be adopted in which slip number data corresponding to each lottery result and the stopping order of each reel 32L, 32M, 32R is derived during rotation of the reels 32L, 32M, 32R. .

  As the process for setting the stop information, stop information first setting process executed in step S310 of the lottery process (FIG. 11) and stop information executed in step S410 of the reel control process (FIG. 12). The second setting process exists. In the stop information first setting process, stop information is set according to the lottery process result.

  The stop information second setting process is a process of changing the stop information stored in the RAM 74 in the stop information first setting process or the previous stop information second setting process after the reels are stopped. In the stop information second setting process, the stop information is changed based on the set winning data, the stop order of the reels 32L, 32M, and 32R, and the stop output of the stopped reels 32L, 32M, and 32R. To do.

  If it is determined in step S409 that all the reels 32L, 32M, and 32R are stopped, a winning determination process is executed in step S411. The winning 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 winning 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 is established, it is further determined whether or not the winning combination is corresponding to winning data set in the RAM 74. If the winning winning combination corresponds to the winning data, the winning winning combination and the number of payouts corresponding to the winning winning combination are set in the RAM 74. On the other hand, if the winning combination does not correspond to the winning data, 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 button 67 is operated. When the winning determination process is completed, a winning result command is set in step S412 so that the sub-control device 80 can recognize the winning combination in the current game, and the reel control process is ended.

<Operation Principle of Stepping Motor 33>
Next, the stepping motor 33 for rotating the reels 32L, 32M, 32R will be described in more detail.

  FIG. 13A is a connection diagram showing a drive system of the stepping motor 33, and FIG. 13B is a diagram showing drive characteristics of the stepping motor 33. FIG. 14A and FIG. 14B are explanatory diagrams for explaining the contents of phase excitation.

  In the present embodiment, a hybrid (HB) type two-phase stepping motor employing a 1-2 phase excitation method is used as the stepping motor 33. Note that the stepping motor is not limited to a hybrid type or two-phase, and various stepping motors such as a four-phase or five-phase stepping motor can be used.

  As shown in FIG. 13A, the hybrid stepping motor 33 includes a rotor 91 disposed in the center and a stator 90 having first to fourth poles 92 to 95 disposed around the rotor 91. And. The rotor 91 is composed of a front side rotor 91a magnetized to the N pole and a back side rotor 91b magnetized to the S pole, and teeth and teeth provided around the front side rotor 91a. In between, it is attached to a rotating shaft in the state shifted relatively by 1/2 pitch so that the tooth | gear provided around the back side rotor 91b may be located. A cylindrical magnet (not shown) is attached between the front side rotor 91a and the back side rotor 91b.

  As shown in FIG. 13B, the exciting coil L0 and the exciting coil L2 are bifilar wound around the first pole 92 and the third pole 94, and the winding end end of the exciting coil L0 and the winding start end of the exciting coil L2 Are connected, and a predetermined DC power source + B (for example, +24 volts) is applied thereto. Similarly, the excitation coil L1 and the excitation coil L3 are also bifilar wound around the second pole 93 and the fourth pole 95, and the winding end of the excitation coil L1 and the winding start end of the excitation coil L3 are connected. Power supply + B is applied.

  An excitation signal is applied to the excitation coil L0 of the first pole 92, the phase that excites the first pole 92 to the S pole and the third pole 94 to the N pole is the A phase, and conversely, the third pole The phase in which the excitation signal is applied to the excitation coil L2 of 94 to excite the first pole 92 to the N pole and the third pole 94 to the S pole is referred to as a reverse A phase. Similarly, an excitation signal is applied to the excitation coil L1 of the second pole 93 to excite the second pole 93 to the S pole and the phase to excite the fourth pole 95 to the N pole as the B phase. The phase in which the excitation signal is applied to the excitation coil L3 of the fourth pole 95 to excite the second pole 93 to the N pole and the fourth pole 95 to the S pole is referred to as an inverted B phase.

  The excitation signal for the stepping motor 33 is given as excitation data to the motor driver 96 shown in FIG. This excitation data is stored in the RAM 74 of the main controller 70, and appropriate excitation data is output by timer interrupt processing. The excitation phase for the stepping motor 33 is determined by this excitation data, and an excitation signal (current) is applied to the excitation phase.

  When the stepping motor 33 is a one-phase excitation drive system, the rotor 91 is moved clockwise or counterclockwise by sequentially applying excitation signals to the A phase, B phase, reverse A phase, and reverse B phase. It can be rotated. That is, for example, when the A phase is first energized, the protrusion of the first pole 92 that is the S pole and the teeth of the front rotor 91a, the protrusion of the third pole 94 that is the N pole, and the teeth of the back rotor 91b Facing each other by the attractive force, and then energizing the B phase, the projection of the second pole 93 and the teeth of the front rotor 91a that become the S pole, the projection of the fourth pole 95 that becomes the N pole and the rear side rotation When the teeth of the child 91b face each other by suction force and then the reverse A phase is energized, the protrusion of the first pole 92 that becomes the N pole, the tooth of the back rotor 91b, and the third pole 94 that becomes the S pole And the teeth of the front side rotor 91a face each other by suction force, and then when the reverse B phase is energized, the projection of the second pole 93, which is the N pole, the teeth of the back side rotor 91b, and the S pole The protrusion of the fourth pole 95 and the teeth of the front rotor 91a are respectively Face by the suction force. By exciting in this order, the rotor 91 rotates clockwise in FIG.

  In the slot machine 10, the one-phase excitation and the two-phase excitation are alternately performed in the acceleration period from the start of rotation of the reels 32L, 32M, and 32R to the constant speed rotation and the period for maintaining the constant speed rotation. 1-2 phase excitation drive is used. In the 1-2 phase excitation drive, excitation is performed according to the following excitation sequences (excitation order) (1) to (8). That is, only one set of excitation is one-phase excitation, and two-phase excitation is to excite two phases simultaneously. Therefore, as shown in FIG. Energize the phase (1 phase excitation), (2) Energize both the A phase and B phase (2 phase excitation), (3) Energize the B phase, and (4) B phase and reverse A phase (5) Energize reverse A phase, (6) Energize both reverse A phase and reverse B phase, (7) Energize reverse B phase, (8) Reverse B phase and A It is a drive system in which both phases are energized and then return to (1). In the present embodiment, since the reel makes one round by the excitation signal of 504 pulses, the angle change based on the excitation signal of 1 pulse, that is, the angle change per step is about 0.714 °.

  FIG. 15 is an explanatory diagram for explaining an example of an excitation pattern when the rotation of the reels 32L, 32M, and 32R is started.

  In the hybrid (HB) type two-phase stepping motor adopting the 1-2 phase excitation method such as the stepping motor 33, as the initial excitation phase at the time of acceleration, besides the one-phase excitation that drives only a specific excitation phase Two-phase excitation in which two specific excitation phases are driven simultaneously can be considered. Although it differs depending on the size of the reel and inertia, the reel can be accelerated from the initial speed of zero even with one-phase excitation in a normal slot machine. However, since the two-phase excitation has a larger rotational torque than the one-phase excitation, the initial excitation is preferably the two-phase excitation in order to obtain a sufficient initial speed.

  In the excitation pattern shown in FIG. 15, this excitation state is maintained for 130 interrupts (193.7 msec) after the two-phase excitation is set in synchronization with the interrupt timing every 1.49 msec. The two-phase excitation as the initial excitation has an excitation order corresponding to the excitation phase at the previous rotation stop among the excitation order 2, excitation order 4, excitation order 6 and excitation order 8 shown in FIG. Will be selected.

  After the two-phase excitation state is maintained for 130 interrupts, the 1-2 phase excitation is alternately repeated. As shown in FIG. 15, the two-phase excitation holding period and the two-phase excitation holding period are shown in FIG. The excitation holding period of excitation is finely controlled. Specifically, the holding period is set to be gradually shortened, such that 1-phase excitation is performed for 8 interrupts following 2-phase excitation, which is the initial excitation, and the next 2-phase excitation is performed for 7 interrupts. Finally, the normal 1-2 phase excitation is set so that the excitation phases are sequentially switched at the minimum interruption interval. Therefore, when the last excitation phase in FIG. 15 is two-phase excitation and the holding period is one interrupt, the first excitation phase in the constant speed rotation period is one-phase excitation and the holding period is one interrupt. . In this way, by sequentially shortening the holding period in each excitation phase as it approaches constant speed rotation, high-speed acceleration processing can be realized in a short time, and smooth transition to constant speed rotation becomes possible.

  On the other hand, when the stepping motor 33 is stopped, three-phase excitation or four-phase excitation is used. In the three-phase excitation, a total of three phases, ie, one phase corresponding to the target stop angle position and two phases that are different from each other by 90 degrees are excited. Specifically, as shown in FIG. 14B, when the A phase or the reverse A phase is one phase corresponding to the target stop angle position, the B phase is added to the A phase or the reverse A phase. Energize phase and reverse B phase. On the other hand, when the B phase or the reverse B phase is one phase corresponding to the target stop angle position, the A phase and the reverse A phase are excited in addition to the B phase or the reverse B phase.

  By exciting the phase corresponding to the target stop angle position, the stop position of the rotor 91 of the stepping motor 33 can be reliably set to a predetermined position. In addition, when two opposite phases are excited, the magnetic fluxes cancel each other. However, during the rotation of the stepping motor 33, a back electromotive force is generated by the induced voltage. For example, a difference in current flowing between the A phase and the reverse A phase. Torque is generated. For this reason, even if it is a case where two opposite phases are excited, braking force will generate | occur | produce. The braking force in the case of three-phase excitation is larger than that in the case of one-phase excitation and smaller than that in the case of two-phase excitation.

  In the four-phase excitation, all of the A phase, reverse A phase, B phase and reverse B phase are excited. As already described, when two opposite phases are excited, the magnetic fluxes cancel each other. However, during the rotation of the stepping motor 33, a counter electromotive force is generated by the induced voltage and flows, for example, to the A phase and the reverse A phase. A torque with a difference in current is generated. In the case of four-phase excitation, the torque is generated in two opposite phases. Therefore, it is possible to generate a braking force even with four-phase excitation. However, the braking force in the case of 4-phase excitation is smaller than that in the case of 1-phase excitation.

  When stopping the stepping motor 33, four-phase excitation is basically used among three-phase excitation and four-phase excitation. A case where the stepping motor 33 is stopped using the four-phase excitation will be described with reference to the explanatory diagram of FIG. In the following description, the stop mode shown in FIG. 16A is referred to as a normal stop mode.

  When the stepping motor 33 is stopped in the normal stop mode, as shown in FIG. 16A, four-phase excitation is generated by generating a stop command in a situation where one-phase excitation and two-phase excitation are alternately repeated. Is started. In this case, the timing at which the four-phase excitation is started is set to the timing after the two-phase excitation is executed over one interrupt. This four-phase excitation is continued for 67 interruptions (99.8 msec). Then, after performing 4-phase excitation over 67 interrupts, 1-phase excitation is performed over 67 interrupts (99.8 msec), and then the 1-phase excitation is terminated. The phase to be subjected to the one-phase excitation is one phase corresponding to the target stop angle position.

  In the normal stop mode, the rotor 91 of the stepping motor 33 can be smoothly stopped by using the four-phase excitation having the weakest braking force when starting braking as described above. However, when four-phase excitation is performed due to weak braking force, the rotor 91 advances to some extent from the timing at which the four-phase excitation is started due to inertia. The number of steps advanced by this inertia varies depending on the specifications of the reel unit 31, and the number of steps can be grasped to some extent at the design stage by experiments using the reel unit 31, but is not constant. Some variation can occur. On the other hand, after four-phase excitation is performed over a predetermined period, the stop position is determined by performing one-phase excitation for one phase corresponding to the target stop angle position over a predetermined period. The designed position can be obtained.

  Next, a case where the stepping motor 33 is stopped using three-phase excitation among three-phase excitation and four-phase excitation will be described with reference to an explanatory diagram of FIG. In the following description, the stop mode shown in FIG. 16B is referred to as a special stop mode.

  When the stepping motor 33 is stopped in the special stop mode, as shown in FIG. 16B, three-phase excitation is generated by generating a stop command in a situation where one-phase excitation and two-phase excitation are alternately repeated. Is started. Since braking is performed by three-phase excitation, which has a stronger braking force than four-phase excitation, the stepping motor 33 can be stopped more rapidly than in the case of four-phase excitation. As a result, the reels 32L, 32M, and 32R stop while swinging between the rotation direction so far and the opposite direction, and it is possible to give the player the impression of stopping while bouncing. Become.

  However, a phenomenon in which the intended stop position is not obtained may occur if the three-phase excitation is performed after the two-phase excitation because the three-phase excitation has a stronger braking force than the four-phase excitation. Therefore, the timing at which three-phase excitation is started is determined not as the timing after two-phase excitation is executed over one interrupt, but as the timing after one-phase excitation is executed over one interrupt. . The three-phase excitation is continued for 67 interruptions (99.8 msec), and then the excitation to the stepping motor 33 is finished. Incidentally, as described above, in the three-phase excitation, a total of three phases, ie, one phase corresponding to the target position of the stop angle and two phases different from each other by 90 degrees are excited.

  Next, stop control processing executed by the MPU 72 of the main controller 70 will be described with reference to the flowchart of FIG. The stop control process is executed in the stepping motor control process in step S106 in the timer interrupt process (FIG. 8).

  First, in step S501, it is determined whether or not “1” is set in a stop control start flag provided in the RAM 74. The stop control start flag is a flag for specifying in the MPU 72 that the situation is after the stop control is started for any of the reels 32L, 32M, 32R. If "1" is not set in the stop control start flag, a stop command has already been issued for any of the reels 32L, 32M, 32R in step S502, but stop control for that has not started. It is determined whether the situation is present. In step S503, it is determined whether the current excitation is two-phase excitation. In step S504, the base position (lower stage in the present embodiment) has been reached with respect to the reels 32L, 32M, and 32R to be stopped. It is determined whether or not the reaching symbol matches the stop symbol determined in step S407 of the reel control process (FIG. 12).

  If a negative determination is made in any of steps S502 to S504, the stop control process is terminated as it is, and if an affirmative determination is made in all of steps S502 to S504, the process proceeds to step S505. In step S505, “1” is set to the stop control start flag of the RAM 74.

  Thereafter, in step S506, it is determined whether or not “1” is set in a special stop flag provided in the RAM 74. The special stop flag is a flag for specifying in the MPU 72 whether or not the stop mode of the stepping motor 33 is set to the special stop mode. The special stop flag is a predetermined probability (from 0%) in the case of winning at any of IV = 1 to 16 in the lottery process (FIG. 10) executed by the MPU 72 of the main controller 70 in the normal gaming state. “1” is set with a probability of less than 100%. Specifically, in the normal gaming state, if you win at any of IV = 1 to 10, you will win the BB role, but if you win at any of these IV values The first special stop lottery process (winning probability is 20%) is executed, and the special stop flag is set to “1” by winning in the lottery process. In addition, if you win at any of IV = 11-16, you will win a small role that can be won at the same time as the BB role, but if you win at any of these IV values The second special stop lottery process (winning probability is 10%) is executed, and the special stop flag is set to “1” by winning in the lottery process. As described above, the special stop flag is set to “1” when the BB combination is won, and is also set to “1” when the BB combination is not won.

  If “1” is not set in the special stop flag (step S506: NO), the normal stop table stored in the ROM 73 is read into the RAM 74 in step S507. In the normal stop table, four-phase excitation is executed over 67 interrupts, and then one-phase excitation for exciting one phase corresponding to the target stop angle position is executed over 67 interrupts. Data indicating what should be done. One phase corresponding to the target stop angle position is determined according to the type of two-phase excitation that is excited immediately before the start of four-phase excitation. Specifically, there are four types of two-phase excitation: A phase and B phase, B phase and reverse A phase, reverse A phase and reverse B phase, reverse B phase and A phase. The type of one-phase excitation is determined in a one-to-one correspondence with each. Further, four types of normal stop tables are prepared corresponding to the fact that there are four types of combinations of four-phase excitation and one-phase excitation in the normal stop mode.

  The type of one-phase excitation executed at the end of the normal stop mode is uniquely determined according to the type of two-phase excitation executed immediately before the normal stop mode is started. Therefore, in step S507, the normal stop table corresponding to the type of the two-phase excitation executed immediately before is read out. By reading the normal stop table, each reel 32L, 32M, 32R is stopped in a normal stop mode using four-phase excitation.

  If “1” is set in the special stop flag (step S506: YES), the special stop table stored in the ROM 73 is read into the RAM 74 in step S508. The special stop table executes 1-phase excitation for 1 interrupt, and then executes 3-phase excitation for 67 interrupts for exciting 3 phases corresponding to the target stop angle position. Data indicating what should be done.

  The three phases corresponding to the target stop angle position are determined according to the type of one-phase excitation that is excited immediately before the three-phase excitation is started. Specifically, there are four types of 1-phase excitation: A-phase, reverse A-phase, B-phase and reverse B-phase. Types are defined. For example, if the previous one-phase excitation is A phase, the A phase, reverse A phase, and reverse B phase are excited, and if the previous one phase excitation is B phase, the A phase, B phase, and reverse B phase are excited. The Further, four types of special stop tables are prepared corresponding to the fact that there are four types of combinations of one-phase excitation and three-phase excitation in the special stop mode.

  The type of one-phase excitation executed at the start of the special stop mode is uniquely determined according to the type of two-phase excitation executed immediately before the special stop mode is started. Therefore, in step S508, the special stop table corresponding to the type of the two-phase excitation executed immediately before is read out. By reading the special stop table, the reels 32L, 32M, 32R are stopped in a special stop mode using three-phase excitation.

  When the special stop table is read, the configuration is not limited to the configuration in which all the reels 32L, 32M, and 32R are stopped in the special stop mode, and some of the reels 32L, 32M, and 32R are special. It is good also as a structure stopped in the stop mode. Further, some of the reels 32L, 32M, and 32R may be configured to be more easily stopped in a special stop mode when the BB combination is won than the other reels.

  When an affirmative determination is made in step S501, when the process of step S507 is executed, or when the process of step S508 is executed, the stop control process is terminated after the stop process is executed in step S509. .

  FIG. 18 is a flowchart showing the stop process.

  First, in step S601, 1 is subtracted from the value of the switching interval counter provided in the RAM 74. When the value of the switching interval counter is “0”, the state of “0” is maintained. In a succeeding step S602, it is determined whether or not the value of the switching interval counter is “0”. The switching interval counter is a counter for specifying the timing for switching the excitation phase when the stepping motor 33 is stopped. When the stop control of the stepping motor 33 is started, the value of the switching interval counter is decremented by 1 every time the timer interrupt process is started once. Further, since the value of the switching interval counter is “0” immediately after executing the process of step S507 or step S508, an affirmative determination is made in step S602 immediately after executing any of these processes. It becomes.

  If the value of the switching interval counter is not “0”, the process during this stop is terminated as it is. If the value of the switching interval counter is “0”, the stop table currently read to the RAM 74 is referred to in step S603. Specifically, when the normal stop table is read, the normal stop table is referred to, and when the special stop table is read, the special stop table is referred to.

  Thereafter, in step S604, it is determined whether there is excitation data to be set next. If the normal stop table has been read out, immediately after the table is read out, four-phase excitation data exists as the next excitation data, and the four-phase excitation takes 67 interrupts. 1 phase excitation data exists as the next excitation data, and after the 1 phase excitation is executed over 67 interrupts, the next excitation data exists. It will not be. If the special stop table has been read out, immediately after the table is read out, one-phase excitation data exists as the next excitation data, and the one-phase excitation is executed for one interrupt. If the three-phase excitation data has been executed for 67 interrupts, the next excitation data does not exist after the three-phase excitation has been executed for 67 interrupts. It will be.

  If an affirmative determination is made in step S604, the next excitation data reading process is executed in step S605, and then the stop process is terminated. Thereby, the phase corresponding to the next excitation data is excited. In step S605, a value corresponding to the period for which the newly set phase excitation is continued is set in the switching interval counter. For example, when the normal stop table is read, when the four-phase excitation is newly started, “67” is set in the switching interval counter, and when the normal stop table is read, one phase is set. When excitation is newly started, “67” is set in the switching interval counter. In addition, when the one-phase excitation is newly started when the special stop table is read, “1” is set to the switching interval counter, and when the special stop table is read, the three-phase excitation is set. When excitation is newly started, “67” is set in the switching interval counter.

  On the other hand, if a negative determination is made in step S604, the excitation performed so far is terminated in step S606, and the stop control start flag value is cleared to “0” in step S607. Terminates the stopped process.

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

  As stop control modes when stopping the reels 32L, 32M, and 32R, a normal stop mode (corresponding to a predetermined stop mode) in which braking force is applied by four-phase excitation and a special stop mode (specific specification) in which braking force is applied by three-phase excitation Corresponding to the stop mode). As a result, when the reels 32L, 32M, and 32R are stopped, the reels 32L, 32M, and 32R are stopped smoothly and the reels 32L, 32M, and 32R are intentionally shaken and stopped. This makes it possible to diversify the stopping modes of the reels 32L, 32M, and 32R. In this case, the normal stop mode and the special stop mode differ not only in the type of phase excitation for applying the braking force but also in the phase excitation mode. Thereby, compared with the structure which makes a stop mode different only by the kind of phase excitation, the freedom degree of the design of stop control for setting each stop mode is raised, and the setting of a stop mode is facilitated.

  When a braking force is applied by three-phase excitation, one-phase excitation is performed immediately before the three-phase excitation. As a result, in the configuration in which the three-phase excitation has a larger braking force than the four-phase excitation, the one-phase excitation in which the torque is smaller than the three-phase excitation is performed immediately before the three-phase excitation, and the rotor 91 is stopped at a desired position. It becomes easy.

  When a braking force is applied by four-phase excitation, one-phase excitation is performed immediately after the four-phase excitation. Thus, immediately after the four-phase excitation, one-phase excitation having a torque larger than that of the four-phase excitation is performed, and the rotor 91 can be easily stopped at a desired position. In addition, since the phase excitation performed immediately after the four-phase excitation is the one-phase excitation, it is possible to achieve the excellent effects as described above while suppressing the number of phases to be excited.

  In addition, it is not limited to the description content of embodiment mentioned above, A various deformation | transformation improvement is possible within the range which does not deviate from the meaning of this invention. For example, you may change as follows. Incidentally, the following configuration of another embodiment may be applied individually or in combination to the configuration of the above embodiment.

  (1) When performing stop control in the normal stop mode, a configuration in which four-phase excitation is performed after one-phase excitation may be used instead of a configuration in which four-phase excitation is performed after two-phase excitation. Alternatively, a configuration may be employed in which three-phase excitation is performed after one-phase excitation or two-phase excitation performed to rotate the reels 32L, 32M, and 32R at a constant speed, and then four-phase excitation is performed.

  (2) When performing stop control in the normal stop mode, the four-phase excitation is executed for 67 interrupts and then the one-phase excitation is executed for 67 interrupts. However, these four-phase excitation and one-phase excitation are performed. The period to be performed is not limited to 67 interrupts, and may be longer or shorter. Further, the period for performing the four-phase excitation and the period for performing the one-phase excitation are not limited to the same configuration, and the period for performing the four-phase excitation may be longer than the period for performing the one-phase excitation. In other words, the period in which the four-phase excitation is performed may be shorter than the period in which the one-phase excitation is performed.

  (3) When performing stop control in the normal stop mode, the configuration is not limited to the one-phase excitation after performing the four-phase excitation, and the two-phase excitation may be performed after the four-phase excitation. It is good also as a structure which performs 3 phase excitation after performing 4 phase excitation.

  (4) When performing stop control in the special stop mode, the configuration is such that the one-phase excitation performed just before the three-phase excitation is performed only for one interrupt, but the one-phase excitation may be performed for two or more interrupts.

  (5) In each of the above embodiments, an example in which the slot machine 10 is embodied has been shown. However, the present invention may be applied to a pachinko machine, or may be applied to a gaming machine of a type in which a slot machine and a pachinko machine are integrated. Also good.
