Description

The present invention relates to a game machine such as a rotating cylinder type game machine, other slot machines, and an arcade game machine. In particular, the present invention relates to a gaming machine provided with a reel driven by a stepping motor and capable of using a stepping motor having the same specifications even if the number of symbols on the reel is reduced.

In Patent Document 1, a 21-frame reel with 21 symbols and a 20-frame reel with 20 symbols are described as having a one-step angle of about 1.43 degrees and a total step angle of 252 and one-phase excitation. It has been proposed to drive by the same stepping motor that repeats 2-phase excitation by 1-2-phase excitation, which makes 1/2 step angle per step update and makes one rotation by 504 step update.

That is, in the case of a 21-frame reel, an equal number of steps of 504/21 = 24 steps is assigned to each symbol, and in the case of a 20-frame reel, a pattern in which one is assigned 26 steps and four are assigned 25 steps is repeated four times, and an excitation pulse is applied. The interrupt time for updating one step is 1.49 ms, and in the steady state, both are rotated once at 1.49 ms × 504 ≒ 751 ms and rotated about 79.9 revolutions per minute, and 20 players who are accustomed to 21-frame reels Even if a game is played on a coma reel, the timing of so-called push-pushing can be measured to the same extent by the same reel rotation cycle.

In addition, if the maximum stop time is 4 frames, if it is a 21-frame reel, 1 interrupt required to detect the stop operation by the stop button, and 0 that is one upstream by passing the symbol that has reached the predetermined reference position when the stop operation is detected. A maximum of 24 interrupts required to pull the symbol of the first frame to the reference position, a maximum of 96 interrupts required to pull the symbol of the fourth frame to the reference position, and thus 121 interrupts in total, so 1.49 ms × 121 ≈ 180.29 ms For 20-frame reels, 1 interrupt required to detect the same stop operation, up to 26 interrupts required to pull the symbol of the 0th frame to the reference position, and up to 100 interrupts required to pull the symbol of the same maximum 4th frame to the reference position. Therefore, 127 interrupts in total, therefore 1.49 ms × 127 ≈ 189.23 ms, are set to satisfy the maximum stop time of 190 ms specified in the game machine rules.

In the first place, the 21-frame reel was the model of the so-called No. 0 era before the game machine rules were enacted in 1985, and the display window of the 3-panel 5-line machine. Most models are still present because it is convenient for the symbol arrangement and reel control to be a multiple of 7 frames in total, which is the display symbol of the upper, middle, and lower three stages and the four frames that slide from the upstream. It is adopted in.

On the other hand, with some exceptions, the 20-frame reel has one line such as the middle stage without intentionally specifying the effective line since the era of Unit 5 under the current game machine rules revised in 2004. Models that use only the effective line internally have become the mainstream, and it is not always necessary to stick to multiples of 7, but rather, each symbol becomes easier to see, and all symbols are created on the RAM for reel stop control. It has been gradually attracting attention because it can save the capacity of the stop candidate search data and the stop table resident in the ROM by one symbol and contribute to the reduction of the memory capacity of the main control device. Therefore, at present, a mixed situation of 21-frame reels and 20-frame reels is occurring.

Japanese Unexamined Patent Publication No. 2012-187212

According to Patent Document 1, even for a 20-frame reel, the stop time at the time of sliding a maximum of 4 frames is 189.23 ms, which can be satisfied within the first specified time of 190 ms specified by the game machine rules. However, if there is no margin and there is a delay in software processing such as when the processing of the interrupt prohibited section is inserted, 190 ms may be exceeded.

In addition, even if there is no delay in software processing, the first reel that regulates one or more reels at the time of operation of the second type special accessory, which is the accessory that operates the condition device related to the winning regardless of the result of the internal lottery. It is not possible to clear within the second specified time of 75 ms, which is shorter than the specified time. That is, one interrupt required to detect the stop operation by the stop button, passing the symbol that has reached the predetermined reference position when the stop operation is detected, and pulling the symbol of the 0th frame one upstream to the reference position is a maximum of one frame. The maximum 25 + 26 = 51 interrupts required to pull the eye symbol to the reference position, and thus 52 interrupts in total, thus 1.49 ms × 52 ≈ 77.5 ms, which exceeds 75 ms.

An object of the present invention is to provide a game machine capable of stopping a desired symbol within a predetermined specified time while being able to use a stepping motor having the same specifications used when the number of symbols on the reel is small or large. is there.

In order to solve the above problems, Yu technique machine, a stepping motor for one revolution a reel in which a plurality of symbols is attached to the periphery, the reel, number of steps is not divisible by attached a symbol number to said reel, The internal lottery means for executing the internal lottery for determining the winning or failing of a predetermined combination, and the stop symbol determined based on the internal lottery result and the stop operation by the player are stopped at a predetermined reference position within a predetermined specified time. Each of the reels is provided with 20 symbols to which an even number of steps is assigned, and 2 symbols to which 24 steps are assigned and 26 steps are assigned. A predetermined pattern in which the three symbols are arranged is repeatedly arranged four times, and in the reel, only two symbols to which the 26 steps are assigned are continuous.

When the specified number of medals are reached, the start lamps ELs light up and the start operation by the start lever 5 becomes possible. If more medals are inserted into the medal slot 2 without operating the start lever 5 from the state where the specified number is reached, the counter of the credit display DL1 is advanced and up to 50 medals, which is a predetermined upper limit, can be stored. Up to 50 medals paid out by winning are also added to the credit, and medals paid out in excess of 50 medals are received by the medal tray 8G from the medal payment exit 8M.

As shown in FIG. 2, each reel 1L, 1C, 1R is a 21-frame reel in which the number of equal steps 24 is assigned to each of the 21 symbols as the first symbol number by the reel bands 10L, 10C, 10R corresponding to the same diameter. Or, as the second number of symbols, a 20-frame reel is configured in which the number of uneven steps 26 and 24 is assigned to each of the 20 symbols. On the outer peripheral surface of each reel band 10L, 10C, 10R, all 10 types of patterns of red 7, white 7, bar, cherry, watermelon 1, watermelon 2, bell, replay, blank 1, blank 2 are printed on the 21-frame reel. Corresponding to symbol numbers 0 to 20 (circled numbers), and corresponding to symbol numbers 0 to 19 (circled numbers) on 20-frame reels, each is drawn by printing or the like according to a unique vertical arrangement. One of the 21-frame reel and the 20-frame reel is adopted depending on the model, and the 20-frame reel is used in the model to which the present invention is applied. Needless to say, the symbol number, symbol name, and number of steps are not printed on the actual reel bands 10L, 10C, and 10R.

The number of non-uniform steps in the 20-frame reel is 26 for the one with a large number of steps and 24 for the one with a small number of steps, and the difference is an even number of 2 or more. Specifically, 2 steps is the most preferable example. It is an even number. The smaller number for each symbol corresponding to symbol numbers 1, 3, 6, 8, 11, 13, 16, 18 in which the remainder of the integer solution obtained by dividing symbol numbers 0 to 19 including 0 in a 20-frame reel by 5 is an odd number. 24 steps, which is an even number of steps, is assigned, and the number of even steps, which is the larger number in each of the other symbols 0, 2, 4, 5, 7, 9, 10, 12, 14, 15, 17, and 19, is 26. Allocate steps. In this way, the symbol to which the number of steps 26 is assigned and the symbol to which the number of steps 24 are assigned are arranged by a predetermined repeating pattern (four times repeating pattern of "26, 24, 26, 24, 26"), and the number of uneven steps is set. Even in the 20-frame reels to be assigned, the symbols are arranged substantially evenly on the outer periphery of each reel 1L, 1C, 1R.

As shown in FIG. 3, each reel 1L, 1C, 1R has a hub 13 at the center directly connected to the shaft SH, which is the drive shaft of the stepping motor SM (12L, 12C, 12R), and a plurality of, for example, four reels extending radially. The spokes 14 of the above, the left and right rings 15a and 15b to which the reel bands 10L, 10C and 10 are wound and attached, and the rim 15 having a plurality of connecting pieces 15c are used as components, and each of these components is light-transmitting. Alternatively, the reel drum 16 is made of a material having good light reflectivity, for example, a transparent resin material. The index IDs (1Li, 1Ci, 1Ri) provided on the reels 1L, 1C, 1R are provided via three mounting portions 17 for engaging the bifurcated claws 17b with the claw holes 17a provided on the three spokes 14 of the reel drum 16. A semi-arc-shaped material with a good light-shielding property, such as a black resin material, with an angle of 180 degrees to see the on-edge portion 18a and the off-edge portion 18b during normal rotation, and the on-period and off-period are generated exactly half a turn. It is composed of a band part 18 formed by.

The band component 18 is well held in a bow shape equidistant from the center of the shaft SH by being supported at three points by the three attachment portions 17 so that both ends are stretched and the center is pushed toward the center. The band member 18 passes through the gap GP of each index sensor IDs (11L, 11C, 11R) composed of photosensors supported on the stationary member side. The passage of the on-edge portion 18a through which the band component 18 blocks the light of the gap GP and the passage of the off-edge portion 18b through which the light passes again appear exactly every half turn, and during one rotation, two reel displacement angles, that is, the on-edge correspondence angle and the off-edge The number of steps of the excitation pulse supplied to the stepping motor SM can be corrected by the corresponding angle. In the remarks column, the index sensors IDs are shown by a simplified notation in which the tip of the wedge is directed to the light blocking and passing positions. Each index sensor IDs and each stepping motor SM are supported by a motor plate 19 which is one of the components of the reel box housed in the housing.

In the 20-frame reel, for example, when the symbol No. 0 arrives at the reference position in the middle stage of the display window 80 and starts to pass, the on-edge portion 18a reaches the index sensor IDs and the index sensor IDs When the on-edge that switches from off to on is detected and the symbol with symbol number 10 displaced 180 degrees from symbol number 0 arrives and begins to pass, the off-edge portion 18b is separated from the index sensor IDs and the index sensor IDs An off-edge that switches from on to off is detected.

When on-edge is detected, symbol number 0 is added to the symbol counter FGC for managing the current symbol that reaches and passes the reference position as the 0 correction value of the total number of steps for one rotation, and the symbol that reaches the reference position The initial step number 25 by the descending order management (25 to 0) corresponding to the step number 26 of the symbol number 0 is stored in the step counter SPC for managing the number of update steps by overwriting. When off-edge is detected, the symbol number 10 is set in the symbol counter FGC and the initial step number 25 corresponding to the step number 26 of the symbol number 10 is set in the step counter SPC as a 252 correction value that is half of the total number of steps for one rotation. Each is stored by overwriting. The symbol counter FGC and the step counter SPC are provided on the RAM of the main control device MC for each reel 1L, 1C, 1R.

The reference position does not necessarily have to coincide with the effective line, and may be set in the upper or lower part of the display window 80 or outside the display window 80. If the reference position and the effective line are different, when the symbol to be stopped is stopped at the reference position, the symbol to be stopped is determined so that the symbol corresponding to the winning combination is displayed on the effective line. It will be. The index ID may be a band member having an arbitrary angle such as 120 degrees instead of the band member 18 of 180 degrees. In this case, the correction value at the time of on-edge detection or off-edge detection is set to the respective on-edge corresponding angle or off-edge corresponding angle. Make it a suitable value. Further, instead of the band member, a method of detecting on-edge and off-edge by a disk integrated with the shaft SH may be used. Further, the passage or the like may be detected by two or more index sensors in which one index composed of small protrusions or the like is arranged at a plurality of places, and two or more corrections may be made during one rotation.

As shown in FIG. 4, the control device CN incorporated inside the game machine housing 8B transmits from the main control device MC corresponding to the main board according to the game machine rules and the main control device MC according to the unidirectional communication specification. Includes a peripheral control device SC corresponding to the "peripheral board" in the game machine rules for receiving information. The one-way communication specification refers to a communication specification that satisfies "the signal transmitted by the peripheral board cannot be received" specified in the game machine rules regarding the main board.

The main control device MC includes a main CPU, ROM, and RAM. In the input port I1, each index sensor 11L, 11C, 11R, each stop button 6L, 6C, 6R, bet button 3, settlement button 4, start lever 5, insertion medal sensor 21 provided downstream of the medal insertion slot 2, and a game machine. Each signal of the payout medal sensor 23 provided at the outlet of the medal payout device HP built in the housing 8B is input. From the output port O1, the built-in LEDs 61, 62, 63 of the stop buttons 6L, 6C, 6R are played through the motor driver circuit Dr1, and the stepping motors 12L, 12C, 12R (SM) are played via the LED driver circuit Dr2. The basic lamps 30 are dropped into the medal tray 8G via the solenoid driver circuit Dr3, and the medal blocker 22 is dropped into the medal tray 8G. The medal payout motor 24 of the medal payout device HP is moved through the motor driver circuit Dr4. I'm in control.

On the ROM of the main control device MC, when a specified number of medals are inserted and the start lever 5 is operated, for example, the accessory continuous operation device RBB and the type 2 special related to the type 1 special accessory RB Special role by the character continuous operation device CBB related to the character CB, multiple winning roles (small roles) including a push order small role that can win medals, and multiple replays that can perform the next game without inserting a new medal. An internal lottery means K for executing an internal lottery for determining whether or not a predetermined combination is right or wrong, such as a combination (replay), is constructed. When indicated by the combination of "left symbol"-"middle symbol"-"right symbol" on the effective line (middle), RBB operates with the display of "bar"-"bar"-"bar", and CBB operates with "replay". "-" Bell "-" Bell "is displayed, the replay role is operated by the display of" Replay "-" Replay "-" Replay ", etc., and the small role is" Bell "-" Bell "-" Bell ". ", Etc. will be displayed to win a prize. While the RBB is operating, the RB is always operating, and while the CBB is operating, the CB is always operating. In the internal lottery, when the start lever 5 is operated, the random value extracted from, for example, a 2-byte counter, which is updated at high speed on the RAM of the main controller MC, is classified according to the combination within the range of 0 to 65535 that can be taken. The winning role in the game is determined by which winning area it belongs to.

As for CBB, the so-called symbol attraction rate is 100% and there is no omission, and "replay"-"bell"-"bell" can always be displayed in the winning game. Therefore, there is no gaming state inside the CBB, and the CBB is operating (CB is operating) from the next game. During CBB operation, all winning combinations (small combinations) are placed in the small combination ALL state, and only the right reel 1R is stopped within 75ms, which is the second specified time shorter than the first specified time from the stop operation. It is made to be a specification. The gaming state during CBB operation ends when the predetermined number of acquired medals exceeds, for example, 13, and returns to the original gaming state in which the CBB win is obtained.

Further, on the ROM of the main control device MC, each reel 1L, 1C, 1R is accelerated to the normal rotation side after the operation of the start lever 5 and after the lapse of 4.1 seconds of the minimum game interval from the start of the previous game. The rotating cylinder rotating device control means V1 for controlling the rotating cylinder rotating device referred to in Article 6, Appendix 2 (3) B of the Game Machine Regulations, and the stop button corresponding to each reel 1L, 1C, 1R.

A reel control means V including a rotation stop device control means V2 is constructed.

The rotating cylinder rotating device control means V1 is provided with each reel 1L, 1C, 1R under unsteady rotation including before reaching steady rotation and after power failure due to a power failure or the like under steady rotation. An index flag setting means V10 for turning on the index flag for turning off the set state when the index ID is detected under steady rotation is provided.

Further, when the index ID is first detected in the rotating cylinder rotating device control means V1 after reaching the steady rotation speed from the unsteady rotation speed for each of the reels 1L, 1C, and 1R, the first detection is performed. The first correction means V11 that first corrects the number of steps of the excitation pulse of the stepping motor SM by the correction value corresponding to one reel displacement angle (on-edge correspondence angle or off-edge correspondence angle), and one reel displacement angle related to the first correction, etc. The information for distinguishing from the reel displacement angle of the above is stored by rewriting the correction point flag IPF from the initial value 0 to 1 for on-edge or 2 for off-edge, etc., and the first correction information storage means V12, and after the first correction. , At least until the stop buttons 6L, 6C, 6R are operated, when the index ID at one reel displacement angle related to the initial correction based on the storage of the initial correction information storage means V12 is detected, this one reel displacement angle is set. Indexes at the second and subsequent correction means V13 that correct the number of steps of the excitation pulse by the corresponding correction value, and other reel displacement angles that are not related to the first correction based on the memory of the first correction information storage means V12 after the first correction. A non-correction means V14 is provided for the second and subsequent times in which the number of steps of the excitation pulse is not corrected when the ID is detected.

When the number of steps immediately after the symbol that has reached the reference position at the time of detecting the stop operation by the stop buttons 6L, 6C, 6R is within the predetermined allowable range, the rotation stop device control means V2 has the reference position. The first stop symbol determining means V21 for determining the stop symbol from the predetermined number of frames (5 frames in total or 2 frames in total) following the upstream including the symbol reaching the above, and the reference position when the stop operation is detected. When the number of steps immediately after the arrival of the reached symbol exceeds the predetermined allowable range, the predetermined number of frames (total of 5 frames or total) following the symbol upstream from the symbol without including the symbol reaching the reference position. The condition is that the second stop symbol determining means (V22) for determining the stop symbol from the symbols of 2 frames) and the stop symbol determined by the first or second stop symbol determining means have reached or reached the reference position. Is provided with a stop pulse supply means V23 that supplies a stop pulse to the stepping motor SM.

Further, the rotation stop device control means V2 is subjected to the first correction based on the memory of the first correction information storage means V12 during the slip period until the reel stops based on the stop operation by the stop buttons 6L, 6C, 6R. Even if the index ID is detected at the one reel displacement angle, the exciting pulse step is provided on the condition that the index flag is on in the set state and the stop request flag for which the reel is stopped is on. A non-correction stop processing means V24 that performs stop processing without correcting the number is provided. The non-correction stop processing means V24 is operated not only by turning on the stop request flag but also by turning on the index flag because there is no power recovery in which the index flag once turned on after steady rotation is turned off. This is to ensure that. Therefore, when the index flag is off, the non-correction stop processing means V21 is not operated, and the index flag is turned on and the initial correction is performed again by detecting the index related to the earliest detection after the steady rotation. .. In this case, the stop request flag that was once turned on before the power failure may be invalidated, but if it is enabled, the stop control that is performed after the next interrupt after the index flag is turned on and the initial correction is performed. Will be used for.

Further, on the ROM of the main control device MC, a medal payout means P for paying out a predetermined number of medals if the game result is a prize, and a medal for the next game is automatically inserted in the same specified number if the game result is a re-game operation. Automatic medal insertion means N, promotion from a normal game state in which the winning probability of the re-game combination is 1 / 7.3 to a high-probability re-game state (replay time RT) with a high probability of 1 / 1.52, for example, and vice versa. Game state transition means J that shifts between a plurality of game states including the fall of the game at a predetermined opportunity, freeze lottery to be executed following the internal lottery (freeze here means interrupting the original game progress and performing a predetermined effect. ), The freeze lottery means F that determines the success or failure of the predetermined turning effect that reversely rotates each reel 1L, 1C, 1R at the start of this game or at the start of the next game or later based on the predetermined probability determined for each winning combination. , The rotating cylinder effect executing means G for executing the rotating cylinder effect related to the winning is constructed.

Main control device MC such as stop button 6L, 6C, 6R operation information, game result information, game status information, freeze and rotation effect information, AT operation information, AT instruction information, AT addition information, AT end information, error information, etc. Contains various information to be detected, determined or executed by.

On the ROM of the peripheral control device SC, the navigation according to the AT instruction information output from the AT instruction information output means H4 to the liquid crystal display device 70 or the like based on the received information from the main control device MC, for example, the correct answer pressing order is ". If "left middle right", the stop button to be operated from the speakers 91 to 94 in conjunction with the display of the navigation means X1 and the navigation means X1 that display "123" etc. corresponding to the stop button position is left, middle, or right. Voice navigation means X2 that informs by voice, effect display means Y1 that changes and displays the video development etc. to be displayed on the liquid crystal display device 70 according to the game state, rotation effect, AT period, etc., and the effect from the speakers 91 to 94 in conjunction with this. We are constructing a sound effect output means Y2 that outputs sound and BGM.

As shown in FIG. 5, each stepping motor SM has a rotor Rm with a built-in permanent magnet having a large number of rotor small teeth on the outer periphery of the iron core, and a plurality of sets of magnetic poles having a plurality of stator small teeth on the inner circumference of the magnetic pole. It has a stator Sw in which windings of a phase, a B phase, a C phase (A bar phase (inverted phase of A)), and a D phase (B bar phase (inverted phase of B)) are wound, and one winding. The step of supplying a one-phase excitation pulse to turn on and the step of supplying a two-phase excitation pulse to turn on one winding and the other adjacent windings are alternately repeated. The pulse is displaced by a half step angle (one step angle by updating two steps) by updating one step. Further, by changing the step update direction of the excitation pulse, forward rotation and reverse rotation are possible.

Each stepping motor SM has a one-step angle of about 1.43 degrees, an interrupt time t for updating the excitation pulse by one step, 1.49 ms, and one rotation in 504 steps. Therefore, in the steady state, the 20-frame reel also makes one rotation of each reel 1L, 1C, 1R at 1.49 ms × 504 ≈ 751 ms to rotate about 79.9 rotations per minute, similarly to the 21-frame reel. The stepping motor SM rotates exactly once by step updating 504 times during steady rotation unless so-called step-out, which is out of synchronization, occurs. The average time required for a symbol to move one frame is about 37.6 ms for a 20-frame reel (about 35.8 ms for a 21-frame reel), and the specified time from reel stop operation to stop during normal operation is "190 ms" in the game machine rules. "Within" means that the integer solution of ((190/37.6) -1) = 4 frames is the maximum number of slip frames allowed.

As shown in the stop sequence of [b], the stop pulse for stopping each stepping motor SM wraps each winding of the A phase, the B phase, the C phase, and the D phase for a predetermined time (for example, 201.15 ms corresponding to 135 interrupts). ) Is used for all-phase excitation pulses that turn on all. Since the excitation pulse at the time of initial correction based on the earliest index ID detection is 1-phase excitation and the number of steps for each symbol is an even number, the step update for each symbol starts with 1-phase excitation and ends with 2-phase excitation. In principle, the excitation pulse immediately before supplying the all-phase excitation pulse is two-phase excitation. When a full-phase excitation pulse is supplied next to the two-phase excitation, the rotor Rm of the stepping motor SM is displaced by another 1/2 angle or more, and the physical relationship with the stator Sm is more stable than the two-phase excitation position. It is stopped at the position corresponding to the phase excitation position. Due to inertia, it may slip and stop by a maximum of 8 steps of renewal, but even in this case, it stops at a position corresponding to the one-phase excitation position. Therefore, if an all-phase excitation pulse is supplied next to the two-phase excitation, a smooth and beautiful stop can be performed as a whole. After the stop pulse is supplied by all-phase excitation for a predetermined time, excitation release is performed to turn off all the windings of the A phase, the B phase, the C phase, and the D phase. The stop pulse itself may be 3-phase excitation or 2-phase excitation for a predetermined time instead of full-phase excitation.

As shown in the acceleration sequence of [c], the acceleration process starts excitation from the two-phase excitation pulse pattern immediately before the previous application of the full-phase excitation pulse, and initially has a long 35 interrupt time (35t = 52.15ms). 2-phase excitation of on-time, 1-phase excitation of 5 interrupt time in the next step update when 1 subtraction result (subtraction result for each interrupt) of the sequence counter that manages this on time becomes 0, and then 8 The on-time is gradually shortened to 2-phase excitation during the interrupt time, 1-phase excitation during the interrupt time, 2-phase excitation during the interrupt time, etc., and the steady rotation speed is reached after about 134 ms has elapsed. For all reels 1L, 1C, 1R, after reaching steady rotation, after making the first correction based on the earliest index ID detection, the built-in LEDs 61, 62, 63 of each stop button 6L, 6C, 6R are turned on to stop. The stop operation by the buttons 6L, 6C, 6R can be accepted. The determination that the steady rotation has been reached may be made after a predetermined stop prohibition period of 0 to several tens of ms, for example, 50 ms has been secured after the lapse of about 134 ms of the time required for the acceleration process.

FIG. 6 shows the control flow of each stepping motor SM of each reel 1L, 1C, 1R for each interrupt time of 1.49 ms. First, a motor state flag provided on the RAM that manages whether the motor state of the stepping motor SM is in a stopped state, an accelerated state, a steady rotation state, or a stopped state (transitional state until the stopped state) is set. Confirm (step s1, hereinafter referred to as s + step number). If it is stopped, it will end immediately without doing anything (YES in s2). The acceleration state of YES in s3 is set after the operation of the start lever 5 and after 4.1 seconds of the minimum game interval from the start of the previous game. In the acceleration process, every time the 1 subtraction result of the sequence counter becomes 0 (YES in s4), the excitation pulse patterns of the acceleration sequence shown in FIG. 5 [c] are set in order (s5), and until the acceleration sequence is completed (s5). NO in s6), the number of interruptions corresponding to the on-time of the set excitation pulse pattern is set in the sequence counter (s7). When the acceleration sequence is completed (YES in s6), the initial value 0 is set in the correction point flag IPF (s8), and the motor state is set in the steady rotation state (s9).

In the steady rotation state (YES in s10), the 1-phase excitation pattern or the 2-phase excitation pattern is alternately set for each interruption (s11), and this time when the 2-phase excitation (next 1-phase excitation) is performed (s12). YES), or when there is no change in the detection result of the index sensor IDs and the edge detection of the index ID has not yet been performed (NO in s13), the edge of the index ID is not detected for a long period of time exceeding the predetermined upper limit. The presence or absence is determined (s14). When there is no rotation error due to deviation from the upper limit (NO in s14) and the step counter SPC that manages the number of steps of one symbol has already reached 0 (YES in s15), the current symbol number of the symbol counter FGC is updated. (S16), the initial value of the number of steps corresponding to the updated symbol number is set in the step counter SPC (s17). If the step counter SPC has not reached 0 (NO in s15), the step counter SPC is subtracted by 1 and updated (s18).

In the steady rotation process, even if the detection result of the index sensor IDs changes and the edge of the index ID is detected (YES in s13), the index sensor IDs are turned off even when the index flag is not turned on (NO in s19). When the detection of the on-edge changing from to on (YES in s20), when the correction point flag IPF is still the initial value 0 (YES in s21), after reconfirming whether it is in the steady rotation state (in S22). YES), set the correction point flag IPF to "1" to perform the initial correction at the on-edge corresponding angle (S23), turn the index flag from off to on (S24), and perform the initial correction by on-edge correction (S25). .. After this initial correction, based on the correction point flag IPF = 1 (YES in S26), the second and subsequent corrections are performed by the on-edge correction (S25). If the initial correction is off-edge correction instead of on-edge correction, even if on-edge is detected, on-edge correction is not performed based on the fact that the IPF is not 1 (NO in S26).

As shown in FIG. 7, in the on-edge correction, as the 0 correction value of the total number of steps for one rotation, the symbol counter FGC has the symbol number 0, and the step counter SPC has the initial symbol number 0 corresponding to the number of steps 26. Each of the 25 steps is stored by overwriting. In this way, the initial correction by the on-edge detection related to the earliest detection at the on-edge corresponding angle is performed. The on period is 254 steps, which is longer than the original 252 steps, and the actual off-edge portion 18b is longer than ideal, and even if the off-edge is detected at the 254th step, the correction is not performed here. From the second time onward, the on-edge correction is performed once per rotation only by detecting the same on-edge as the first correction.

On the other hand, in the steady rotation process of FIG. 6, even if the detection result of the index sensor IDs changes and the edge of the index ID is detected (YES in s13), when the index flag is not yet turned on (NO in s19), If the index sensor IDs are off-edge detection that changes from on to off (NO at s20), and if the correction point flag IPF is still the initial value 0 (YES at s27), reconfirm whether it is in a steady rotation state. After that (YES in s28), set the correction point flag IPF to "2" to perform the initial correction at the off-edge corresponding angle (s29), turn the index flag from off to on (s30), and make the initial correction by off-edge correction. (S31). After this initial correction, based on the correction point flag IPF = 2 (YES in s32), the second and subsequent corrections are performed by the off-edge correction (s31). If the initial correction is on-edge correction instead of off-edge correction, even if off-edge is detected, off-edge correction is not performed based on the fact that the IPF is not 2 (NO in s32).

As shown in FIG. 8, in the off-edge correction, the symbol counter FGC corresponds to the symbol number 10 and the step counter SPC corresponds to the number of steps 26 of the symbol number 10 as a 252 correction value which is half of the total number of steps for one rotation. The initial number of steps of 25 is stored by overwriting. In this way, the initial correction by the off-edge detection related to the earliest detection at the off-edge corresponding angle is performed. The off period is 250 steps, which is shorter than the original 252 steps, the actual on-edge portion 18a is longer than ideal, and even if the on-edge is detected at the 502nd step, the correction is not performed here. From the second time onward, the off-edge correction is performed once per rotation only by detecting the same off-edge as the first correction.

In the steady rotation process of FIG. 6, when the edge of the index ID is detected and the index flag is on (YES in s19), it is due to the deviation from the lower limit where the edge of the index ID is detected within a short period of time exceeding the predetermined lower limit. The presence or absence of a rotation error was determined (s33), and if there was no rotation error (NO in s33), it was reconfirmed that the index flag was on (s34), and immediately after that, the stop request flag was confirmed to be on (s35). When the index flag is on and the stop request flag is on (YES in s34 and YES in s35), the step counter SPC is updated (s15 to s18) without correction by detecting the edge of the index ID. , Stop processing based on turning on the stop request flag will be performed (s36). When the stop request flag is on (YES in s36) and the current symbol of the symbol counter FGC is updated to the symbol determined as the stop symbol and the current symbol = stop symbol (YES in s37), the index flag is turned on again. After confirmation (YES in s38), the stop request flag is reset (s39), the all-phase excitation pulse is set (s40), the all-phase excitation time is set (s41), and the motor state is set to the stopped state. (S42).

In the stopped processing in which the motor state is stopped, the all-phase excitation time is subtracted (s43), the result becomes 0 and the time is up (YES in s44), the excitation is released (s45), and the motor is stopped. The state is set to the stopped state (s46). In this way, the rotation and stop of each reel 1L, 1C, 1R are controlled. When a rotation error due to deviation from the upper limit or deviation from the lower limit is detected, the motor state is set to the acceleration state (s47), and the process is repeated from the acceleration process. The detection of rotation error due to deviation from the upper limit (s14) is performed during 2-phase excitation, and the detection of rotation error due to deviation from the lower limit (s33) is performed during 1-phase excitation, and the number of counter bits for determining the error. Is saving.

FIG. 9 shows a reel stop control process called from the game main flow performed by the main control device MC, and a search target constituting the first stop symbol determination means V11 and the second stop symbol determination means V12 to be called by a subroutine in the reel stop control process. The flow of frame determination processing is shown. The reel control process constitutes the reel control means V together with the motor control process of FIG. 6 which is executed for each interrupt. Depending on the winning combination (or winning area) in the internal lottery triggered by the operation of the start lever 5, the winning combination determined by the internal lottery for all the symbols of all reels 1L, 1C, 1R during the acceleration process. Depending on the role, prioritization by role according to the order of replaying role> winning role (small role)> special role, and if the winning role is a winning role (small role), a high payout small role with a large number of payouts The stop candidate search data is initially created on the RAM with priority on the number of coins to be pulled in and priority on the number of small wins with many types of symbol combinations to correspond to the priority on the number of coins to be drawn in (s50).

Acceleration processing of all reels 1L, 1C, 1R is completed and steady rotation is reached, all index flags are turned on, and operations of stop buttons 6L, 6C, 6R can be accepted (s51), and any stop operation is performed. If there is (s52), the search target frame determination process is executed (s53).

First, the number of the current symbol that has reached the reference position and is passing through from the symbol counter FGC is acquired (s54), whether or not the CBB is operating (CB is operating) (s55), and if the CBB is operating, one or more reels. It is determined whether or not the reel should be stopped within the required short second specified time of 75 ms, for example, the right reel 1R (s56). If the CBB is not operating, or if the reel (in this case, the left reel 1L or the middle reel 1C) that can be stopped within the first specified time 190ms even while the CBB is operating is stopped, set 5 (5 frames) to the number of search frames. (S57), set 26-1 = 25 if the current symbol is a 26-step symbol (s58), and set 24-1-1 = 23 if the current symbol is a non-26-step symbol (s59) in the number of comparison steps used for the later determination. Set (s60). When the reel (in this case, the right reel 1R) that should be stopped within the second specified time 75ms during CBB operation is stopped, 2 (2 frames) is set in the number of search frames (s61), and the current symbol is set in the number of comparison steps. For a 26-step symbol, set 26-4 = 22 (s62), and for a non-26-step symbol, set 24-2 = 22 (s64).

Subsequently, the value of the step counter SPC is compared with the number of comparison steps (s65), and when the value of the step counter SPC is not equal to or greater than the number of comparison steps (s66), the symbol currently located one upstream of the symbol number is selected. The pressed position symbol of the stop button, that is, the symbol of the 0th frame is used (s67), and when the value of the step counter SPC is equal to or greater than the number of comparison steps, the symbol of the current symbol number is used as the pressed position symbol, that is, the symbol of the 0th frame (s68). ).

From the above, when the unit is stopped within the first specified time of 190 ms, the number of update steps within the permissible number of times when the value of the step counter SPC reaches the initial number of steps is counted for the first time, that is, 25 or 24 steps in the 26-step symbol. When the number of symbols is 23, the first stop symbol determination means V21 for determining the stop symbol is operated in the range of 5 frames with the current symbol as the 0th frame, and the value of the step counter SPC is updated beyond the permissible number of times. When the number of advanced update steps, that is, 24 to 0 for the 26-step symbol and 22 to 0 for the 24-step symbol, the stop symbol is stopped in the range of 5 frames with the symbol one upstream as the 0th frame without including the current symbol. The second stop symbol determining means V22 for determining is activated.

In addition, when stopped within the second specified time of 75 ms, the number of update steps before the number of step updates required for the value of the step counter SPC to update the reached symbol becomes 22 or less, which is the unacceptable number, that is, the 26-step symbol In the 25th to 22nd and 24th step symbols, when the number is 23 and 22, the first stop symbol determining means V21 for determining the stop symbol is operated in the range of 2 frames with the current symbol as the 0th frame, and the value of the step counter SPC is reached. When the number of update steps after the number of step updates required to update the symbol is 22 or less, which is the unacceptable number, that is, when both the 26-step symbol and the 24-step symbol are 21 to 0, the current symbol is not included. The second stop symbol determination means V22 for determining the stop symbol in the range of two frames with the upstream symbol as the 0th frame is operated.

After the subroutine returns from the search target frame determination process, a logic operation is performed to compare and judge the data recorded on the stop candidate search data for the search target frame of 5 frames or 2 frames (s69), and the search target frame is in 5 frames or 2 frames. When the maximum value of is one (s70), the symbol of the maximum value is determined as the stop symbol (s71). When there are a plurality of maximum values, the only maximum value symbol is determined as the stop symbol by referring to the stop table resident in the ROM in advance (s72).

When the stop of one reel is completed, until all reels 1L, 1C, 1R are stopped (s73), and during the stop operation interval period until the operation of the next stop button can be accepted (for example, for about 200 ms). In addition, the stop candidate search data of the unstopped reel is displayed for the symbols that are not displayed and / or the symbols that are kicked to prevent the completion of the winning combination according to the stopped result. Rewrite and prepare for the next stop operation (s74). When all reels 1L, 1C, 1R are stopped, the game result is determined (s75), and for example, in the case of winning, a medal with a predetermined payout is paid out.

As shown in FIG. 10, in the small winning combination ALL state during CBB operation, all winning winning combination (small winning combination) NML1 to 13 are specified to be duplicated, the middle reel 1C is stopped first, and the second. In the case of the push order "middle left and right", which stops the left reel and the right reel 1R at the third (last), the 13-card winning combination NML11, which is a kind of small winning combination, is won, and the other pushing order. In the case of, a 14-card NML 12 or 13 is won, and by the push order navigation under the assist time AT operation, the 13-card NML 11 is won in the first game by the time the number of acquired cards exceeds 13 when the CBB operation is completed. In the second game, the 14-card combination NML 12 or 13 is won, and the number of medals that can be obtained in total of 27 medals can be adjusted. During the acceleration process before the first stop operation can be accepted, stop candidate search data corresponding to the number of sheets priority is created, and the second stop operation is performed after the first middle reel 1C is stopped. The stop candidate search data will be revised by creating stop candidate search data corresponding to the number priority for unstopped reels by the time it becomes possible to accept.

In the stop candidate search data that corresponds to the number of sheets priority created during acceleration processing under the small winning combination ALL state during CBB operation, 4EH (lower E (10)) corresponds to the "replay" and "bar" symbols for the left reel 1L. 14) in decimal notation corresponds to the number of dividends of NML12 or 13) corresponding to the "watermelon 1", "watermelon 2" and "blank 2" symbols, and 4DH (lower D (13 in decimal notation) is the number of dividends of NML11). 49H (lower 9 is the number of dividends of NML6) corresponding to the "bell" symbol, 42H (lower 2 is the number of dividends of NML8 or 9) corresponding to the "cherry" symbol, "blank 1" 41H (lower 1 is the number of payouts of NML5) is recorded corresponding to the symbol, and 10H is recorded corresponding to the "red 7" and "white 7" symbols. 10H indicates the lowest priority that passively allows the display.

For the middle reel 1L, 4EH corresponds to the "bell" and "replay" symbols, 43H corresponds to the "watermelon 1" and "watermelon 2" symbols (the lower 3 is the number of dividends of NML10), and "white 7". 42H (the lower 2 is the number of payouts of NML7 or 8) is recorded corresponding to the "cherry" symbol, and 10H is recorded corresponding to the "red 7", "bar", "blank 1", and "blank 2" symbols.

For the right reel 1R, 4EH is recorded corresponding to the "white 7", "bar", "bell", "replay", "cherry", and "blank 2" symbols, and 10H is recorded corresponding to the "red 7" and "watermelon 1" symbols. To do. As for the stop candidate search data for small wins other than the push order small win, the value (49H, etc.) in which the number of payouts is set in the lower 4 bits is recorded instead of 40H, following the stop candidate search data corresponding to the number priority. It is preferable to do so. This is because the frequency of referring to the stop table is reduced, and the symbols related to the small winning combination with a higher payout can be drawn from the small winning combination that is duplicated by only the logic operation.

Under the small role ALL state during CBB operation, the second stop operation can be accepted after the first middle reel 1C is stopped (in this case, the middle stop of the "bell" symbol is confirmed). In the stop candidate search data that corresponds to the number priority created by the time, the left reel 1L corresponds to the "watermelon 1", "watermelon 2", "blank 2", "replay", and "bar" symbols and is 45H (lower 5). Is the product of 1 type of each left symbol of NML11 or 12 or 13 and 5 types of right symbol) and 41H corresponding to the "bell" symbol (the lower 1 is 1 type of left symbol and 1 type of right symbol of NML6). (Product), 10H is recorded corresponding to the "cherry", "blank 1", "red 7", and "white 7" symbols, including those that are not eligible for winning due to the first stop.

For the right reel 1L, 43H corresponding to the "white 7", "bar", "replay", "cherry", and "blank 2" symbols (the lower 3 is the product of each 1 type of NML11 right symbol and 3 types of left symbol). 41H (the lower 1 is the product of 1 type of right symbol and 1 type of left symbol of NML6 or 13) corresponding to the "bell" symbol, and "red 7" including those that are not eligible for winning due to the first stop. Record 10H corresponding to the "Watermelon 1" symbol. In addition, when the first stop operation of the middle reel 1C is performed (after the middle stop of the "bell" symbol is confirmed) and the second stop operation of the right reel 1L is performed, the number priority is maintained. However, in this case, based on the confirmation of the middle stop of the "bell" symbol for the middle reel 1C, the number-priority stop candidate search data corresponding to the right reel 1R in the lower left column of FIG. 5 is the "bell" symbol. The stop symbol of the right reel 1R will be determined based on the data in which the initial value of 4EH is rewritten to 49H (corresponding to 9-card combination NML6).

As shown in FIG. 11, when the small winning combination ALL (NML1 to 13) during CBB operation, the middle stop button 6C is pressed first according to the push order navigation displayed on the liquid crystal display device 70 or the like by AT operation. To do. The timing of pressing the stop button does not matter, and the illustrated example is just an example. The same applies hereinafter. When the bell symbol (24-step symbol) of symbol number 11 has reached the middle stage, which is the reference position, and the middle stop button 6C is pressed when the step counter SPC = 23 at the time of arrival, the bell symbol of symbol number 11 is included. The stop symbol will be decided from the following 5 frames. From the stop candidate search data corresponding to the number priority applied at the time of the first stop, the highest number 4EH corresponding to the bell symbol of symbol number 11 and the replay symbol of symbol number 10 is recorded, so that the stop table The bell symbol of symbol number 11 in the 0th frame is determined as the stop symbol (the stop table stores information on the number of sliding frames and priority bit information in which the bell symbol of symbol number 11 should be the stop symbol. ), A stop pulse is supplied by the next interrupt to immediately stop the bell symbol of symbol number 11.

When the first middle stop button 6C is pressed, the bell symbol (24-step symbol) of symbol number 11 has reached the middle stage, which is the reference position, and when the step counter SPC = 22 to 0, the symbol number 11 The stop symbol will be decided from the following 5 frames that do not include the bell symbol. From the stop candidate search data corresponding to the number priority applied at the time of the first stop, the highest number 4EH corresponding to the replay symbol of symbol number 10 and the bell symbol of symbol number 6 is recorded, so that the stop table The bell symbol of symbol number 6 in the fourth frame is determined as the stop symbol (the stop table stores information on the number of sliding frames and priority bit information in which the bell symbol of symbol number 6 should be the stop symbol. ), The bell symbol of symbol number 6 is slid four frames and pulled into the middle stage, and when the symbol number of the symbol counter FGC becomes 6 and the step counter SPC reaches the initial value 23 of the number of steps 24 of symbol number 6, a stop pulse is generated. The bell symbol of symbol number 6 is stopped in the middle stage of the middle reel 1C.

In this case, the maximum stop time is when four frames are slipped when the symbol counter = 11 and the step counter SPC = 22. 1 interrupt required to detect the stop operation by the stop button, 23 interrupts required to pass the bell symbol of symbol number 11 and pull the replay symbol of symbol number 10 in the 0th frame one upstream to the reference position, 4th frame 26 + 26 + 24 + 26 = 102 interrupts required to pull the bell symbol of symbol number 6 to the reference position, thus 126 interrupts in total, therefore, the maximum stop time = 1.49 ms × 126 = 187.74 ms, which is the normal stop specified by the game machine rules. There is a margin of 10 interrupt time or more for the maximum time value of 190 ms.

Secondly, it is assumed that the left stop button 6L is pressed according to the push order navigation displayed on the liquid crystal display device 70 or the like by the AT operation. At the time of the second stop of the left reel 1L after the first stop of the middle reel 1C, the stop candidate search data corresponding to the number priority is applied. When the watermelon 1 symbol (26-step symbol) with symbol number 19 has reached the middle stage, which is the reference position, and the left stop button 6L is pressed when the step counter SPC = 25 at the time of arrival, the watermelon 1 symbol with symbol number 19 has arrived. The stop symbol will be decided from the following 5 frames including. From the stop candidate search data corresponding to the number priority applied at the time of the second stop, the highest number 45H corresponding to the watermelon 1 symbol of symbol number 19 and the replay symbol of symbol number 16 is recorded, so that the stop is performed. With reference to the table, the watermelon 1 symbol of symbol number 19 in the 0th frame is determined as the stop symbol (the stop table contains information on the number of sliding frames and priority bit information in which the watermelon 1 symbol of symbol number 19 should be the stop symbol. (Remembered), a stop pulse is supplied by the next interrupt to immediately stop the watermelon 1 symbol of symbol number 19.

When the second left stop button 6L is pressed, the watermelon 1 symbol (26-step symbol) of symbol number 19 has reached the middle stage, which is the reference position, and when the step counter SPC = 24 to 0, the symbol number 19 The stop symbol will be determined from the following 5 frames that do not include the watermelon 1 symbol. From the stop candidate search data corresponding to the number priority applied at the time of the second stop, the highest highest number 45H is recorded corresponding to the replay symbol of symbol number 16 and the blank 2 symbol of symbol number 14, so that the stop is stopped. With reference to the table, the blank 2 symbol of symbol number 14 in the 4th frame is determined as the stop symbol (the stop table contains information on the number of sliding frames and priority bit information in which the blank 2 symbol of symbol number 14 should be the stop symbol. (Remembered), when the blank 2 symbol of symbol number 14 is slid four frames and pulled into the middle stage, the symbol number of the symbol counter FGC becomes 14, and the step counter SPC becomes the initial value 25 of the number of steps 26 of symbol number 14. A stop pulse is supplied to, and the blank 2 symbol of symbol number 14 is stopped in the middle stage of the left reel 1L.

In this case, the maximum stop time is when four frames are slipped when the symbol counter = 19 and the step counter SPC = 24. 1 interrupt required to detect the stop operation by the stop button, 25 interrupts required to pass the watermelon 1 symbol of symbol number 19 and pull the white 7 symbol of symbol number 18 of the 0th frame one upstream to the reference position, 4 frames 24 + 26 + 24 + 26 = 100 interrupts required to pull the blank 2 symbol of the eye symbol number 14 to the reference position, and thus 126 interrupts in total, therefore, the maximum stop time = 1.49 ms × 126 = 187.74 ms, which is defined by the game machine rules. There is a margin of 10 interrupt time or more for the maximum value of 190 ms of normal stop time.

It is assumed that the right stop button 6R is pressed in the third (last) manner. When the bar symbol (24-step symbol) of symbol number 3 has reached the middle row, which is the reference position, and the right stop button 6R is pressed when the step counter SPC = 24 or 23, the bar symbol of symbol number 3 is included. The stop symbol will be determined from the following two frames. After the second stop, the stop candidate search data corresponding to the number priority for the right reel has been rewritten from the initial value 43H corresponding to the bar of symbol number 3 to 41H. This is because the stoppage of the two reels has already been confirmed, and only one type of own bar symbol is available. In addition, the initial value 41H corresponding to the bell of symbol number 2 has been rewritten to 00H, which prohibits stopping by kicking and not stopping. When the bell symbol stops in the middle stage, "Watermelon 1 or Watermelon 2 or Blank 2"-"Bell"-"Red 7 or Bell", which is separately defined as one of the replay roles other than the small role ALL, is displayed. Because it is done. Since the only maximum value 41H is recorded corresponding to the bar symbol of symbol number 3, the bar symbol of symbol number 3 in the 0th frame is determined as the stop symbol, and the stop pulse is supplied by the next interrupt to provide the symbol number. Immediately stop the bar symbol of 3.

When the third right stop button 6R is pressed, the bar symbol (24-step symbol) of symbol number 3 has reached the middle row, which is the reference position, and when the step counter SPC = 21-0, the symbol number 3 The stop symbol will be determined from the following two frames that do not include the bar symbol. After the second stop, the stop candidate search data corresponding to the number priority for the right reel has been rewritten from the initial value 41H corresponding to the bell of symbol number 4 to 00H, which is prohibited from stopping by kicking. When the bell symbol stops in the middle stage, "Watermelon 1 or Watermelon 2 or Blank 2"-"Bell"-"Red 7 or Bell", which is separately defined as one of the replay roles other than the small role ALL, is displayed. Because it is done. The initial value 43H for replay of symbol number 1 has been rewritten to 41H. This is because the stoppage of the two reels has already been confirmed, and there is only one type of self-replay symbol. Since the only maximum value of 41H is recorded corresponding to the replay symbol of symbol number 1, the replay symbol of symbol number 1 in the first frame is determined as the stop symbol, and the replay symbol of symbol number 1 is slid by one frame. When the symbol number of the symbol counter FGC is 1 and the step counter SPC reaches the initial value 23 of the number of steps 24 of the symbol number 1, a stop pulse is supplied, and the replay of the symbol number 1 is performed in the middle of the right reel 1R. The symbol is stopped.

In this case, the maximum stop time is when one frame slips when the symbol counter = 3 and the step counter SPC = 21. 1 interrupt required to detect the stop operation by the stop button, 22 interrupts required to pass the bar symbol of symbol number 3 and pull the bell symbol of symbol number 2 in the 0th frame one upstream to the reference position, 1st frame 26 interrupts required to pull the replay symbol of symbol number 1 to the reference position, therefore 49 interrupts in total, therefore, the maximum stop time = 1.49 ms × 49 = 73.01 ms, which is 1 or more in the CB specified by the game machine rules. There is a margin of 10 interrupt time or more for the maximum value of 75 ms of the reel stop time. In addition, when the right stop button 6R is pressed, even if the 26-step symbol arrives instead of the 24-step symbol, when the step counter SPC = 21 to 0, the arrival symbol is not included and the drawing is performed from the upstream. The maximum stop time is 1.49 ms × 49 = 73.01 ms, which is the same.

As shown in FIG. 12, the display appearance differs depending on whether the reference position arrival symbol shown in FIG. 11 is stopped immediately or a symbol other than the reference position arrival symbol shown in FIG. 2 is stopped. Can also display the 13-card role NML11, and 13 medals are paid out. In the case of the immediate stop shown in Part 1, since the step counter SPC supplies the stop pulse when the number of steps has been updated from the initial value, the stop pulse is supplied when the step counter SPC has the initial value. Compared to the case of 2, it will be stopped at a position where the update is advanced by several steps from the original ideal stop position, but 1 in the number of step updates is 1 / in the step angle. It is only two corners, and even when a stop pulse is supplied when the step counter SPC = initial value 23 or 25 as ideal, the player may actually have a deviation of several steps due to reel inertia and other factors. In addition, there is almost no difference in appearance.

In the case of the present embodiment, since the right symbols of the 13-card combination NML11 and the 14-sheet combination NML12 are the same 5 types of "white 7", "bar", "replay", "cherry", and "blank 2", the middle reel 1C The number-priority stop candidate search data is created only for the left reel 1L after the first stop, and the right reel 1R is created after the first stop of the middle reel 1C without creating the number-priority stop candidate search data for the right reel 1R. It is also possible to use the stop candidate search data in which the initial value 4EH of the “bell” symbol is rewritten to 49H, and the same result is obtained in this case as well.

In the above embodiment, the reel to be stopped within 75 ms of the second specified time is the right reel 1R regardless of the pushing order, but the left reel 1L or the middle reel 1C may be used, and all or any two reels may be used. Depending on the push order, for example, only the first reel to stop, only the second reel to stop, only the third reel to stop, only the first and second reels to stop, the first Only the reels that are stopped second and third, only the reels that are stopped first and third, and the like may be used. Further, the invention according to claim 1 may be applied to a model that is not equipped with CBB and / or CB and that stops the reels within the first specified time of 190 ms, and the number of symbols on one reel is all. In 16 frames, the smaller even number of steps 30 is assigned to each symbol corresponding to symbol numbers 0, 4, 8 and 12, which are multiples of 4 including 0, and other symbol numbers 1, 2, 3, 5, 6 , 7, 9, 10, 11, 13, 14, 15 can be applied to a 16-frame reel in which the larger even number of steps 32 is assigned and the maximum number of sliding frames is 3.

Further, in the above embodiment, the index can be corrected with a plurality of reel displacement angles, but the index may be corrected with only one fixed reel displacement angle. Further, in the above embodiment, the operation of the assist time AT and the like are determined by the main control device MC, but may be determined by the peripheral control device SC.
