Description

  The present invention relates to a spinning machine, other slot machines, arcade game machines, and other gaming machines. In particular, the present invention relates to a gaming machine that includes a reel that is driven by a stepping motor and that can correct the number of steps of an excitation pulse of the stepping motor by detecting an index at a predetermined reel displacement angle.

  In Patent Document 1, an index for detecting an ON period and an OFF period by half a half by a stationary index sensor is integrally provided on a reel drum that winds a reel band having a plurality of symbols, and the index is detected by the index sensor. At two locations, the reel displacement angle corresponding to the detected on-edge and the reel displacement angle corresponding to the off-edge where the index is not detected by the index sensor, the number of steps of the excitation pulse supplied to the stepping motor is set to each reel displacement angle. Compensates with the corresponding correction value, corrects the correspondence between the number of steps managed by the control device and the design every half circle, and accepts the operation of the stop button than when correcting with one reel displacement angle An invention is described in which the waiting time until the operation can be shortened.

JP-A-7-284553

  According to the technique disclosed in Patent Document 1, the waiting time until the stop operation can be performed can be shortened as compared with the case where the number of steps is corrected only once during one rotation. In a transitional situation from rotation to stop, that is, during slipping, individual differences due to index processing and assembly errors, internal disturbances due to software processing time delays on the control device, external vibration, etc. If the actual index is detected when the number of steps advanced from the original design due to the influence of disturbance, the number of steps will be partially updated, and the design will pass this duplicate update part. The time for moving one frame becomes longer. That is, for example, using a stepping motor that rotates once in 504 steps from 0 to 503 by 1-2 phase excitation, after detecting the on-edge of the index with 0 steps, the off-edge of the index when the number of steps is 252 However, if an off-edge is finally detected at 254, which is two steps ahead, the number of steps is 252, 253, 254 instead of 252, 253, 254, etc. It has been changed redundantly, and one frame movement is originally planned in 26 steps from 252 to 277, but there is an overlap of 2 steps in the middle, so that one frame movement was actually performed in 28 steps. It will be the same. Therefore, if the number of steps is partially changed during a slip, the time to stop takes longer than the original design value, and there is a possibility that the specified stop time limit may be exceeded. This fear similarly occurs when the number of steps is corrected only once during one rotation.

  The specified time limit for stoppage is defined as “190 ms” under the current rules for the time limit from the reel stop operation specified in Article 5 Attached Table 5 (1) A (G) of the gaming machine rule. Exceptional restrictions on the operation of one or more reels from the stop operation to the stop at the time of the operation of the second special agent specified in Article 6 Attached Table 5 (1) F (e) The time is defined as “75 ms” in the current rules.

  An object of the present invention is to provide a gaming machine that can prevent the time from the reel stop operation to the stop from becoming longer than the design value regardless of individual differences, internal disturbances, disturbances, etc., and can perform appropriate reel stop control. There is in point to do.

The reference numerals of the drawings are illustrated in parentheses for illustration.
A reel (1L, 1C, 1R) that has a plurality of symbols and is rotated by step update of the excitation pulse supplied to the stepping motor (SM),
When detecting an index (ID) at a predetermined reel displacement angle detected during one rotation of this reel, it is possible to correct the number of steps of the excitation pulse and accept the stop operation of the reel after the correction of the first number of steps. It is premised on a gaming machine that enables it.

In the above gaming machines,
When the index is detected first after the reel reaches the steady rotational speed from the unsteady rotational speed, the initial correction of the number of steps of the excitation pulse with the correction value corresponding to the reel displacement angle according to the first detection is performed for the first time. Correction means (V11);
After the initial correction, until the reel is stopped, when the index is detected at the reel displacement angle after the initial correction, the number of steps of the excitation pulse is corrected by the correction value corresponding to the reel displacement angle. Correction means (V13) after the first time,
After the stop operation of the reel, during the slip period until the reel is stopped based on the stop operation, the stop process is performed without correcting the step number of the excitation pulse by detecting the index. Stop processing means (V21) is included.

  As a result, during the slip period leading to the stoppage, there was a deviation in which the actual index was detected when the number of steps advanced from the original design due to individual differences, internal disturbances or disturbances. In some cases, no correction is made. For this reason, it is possible to prevent a change in the number of steps from being partially overlapped, to prevent the time until stopping from becoming longer than the original design value, and to perform appropriate reel stop control.

  In the above, further includes an index flag setting means (V10) for setting an index flag to be in an unset state under unsteady rotation of the reel when an index is detected under steady rotation of the reel. The non-correction stop processing means (V21) is operated on condition that the index flag is set and the reel is stopped.

  In this way, since the operation of the non-correction stop processing means was made not only on the reel stop operation but also on the condition that the index flag was in the set state, it was temporarily set in the steady state during the slip period. In the event of a return after power interruption that causes the index flag to be in a non-set state (re-initialization by re-energization after power interruption), the non-correction stop processing means does not operate, and the excitation pulse is detected by detecting the index. It is possible to avoid stopping processing without correcting the number of steps. For this reason, it is possible to prevent inadequate processing leading to a stop while the correspondence between the number of steps managed by the control device and the design is shifted.

The three-lamp lamp EL3 is lit and reaches the specified number. When the specified number of multiplied medals is reached, the start lamp ELs is turned on, and the start operation by the start lever 5 becomes possible. When a medal is further inserted into the medal insertion slot 2 without operating the start lever 5 from the state where the prescribed number has been reached, the counter of the credit indicator DL1 is advanced and can be stored up to a predetermined upper limit of 50 sheets. Up to 50 medals paid out by winning are added to the credit, and medals paid out exceeding 50 are received by the medal tray 8G from the medal payout exit 8M.

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

  The number of unequal steps in a 20-frame reel is 26 for the larger number of steps and 24 for the smaller number of steps, and the difference is an even number of 2 or more, specifically, 2 steps as the most preferable example. Even number. The lesser of the symbols corresponding to symbol numbers 1, 3, 6, 8, 11, 13, 16, and 18 in which the remainder of the integer solution obtained by dividing symbol numbers 0 to 19 including 0 in the 20-frame reel by 5 is odd. 24 steps, which are the even number of steps, are assigned, and the other even number 26 is the number of even steps which is larger in each of the symbols 0, 2, 4, 5, 7, 9, 10, 12, 14, 15, 17, 19 Steps are assigned. In this way, the symbols to which the number of steps 26 is assigned and the symbols to which the number of steps 24 are assigned are arranged in a predetermined repeating pattern (four repetition patterns of “26, 24, 26, 24, 26”), and the number of uneven steps is set. Also in the 20-frame reel to be allocated, the symbols are arranged almost uniformly on the outer periphery of each reel 1L, 1C, 1R.

  As shown in FIG. 3, each of the reels 1L, 1C, and 1R has a hub 13 at the central portion that is directly connected to a shaft SH that is a drive shaft of the stepping motor SM (12L, 12C, and 12R), and a plurality of, for example, four radially extending hubs. The spokes 14, the left and right rings 15a, 15b to which the reel bands 10L, 10C, 10 are wound and pasted, and the rim 15 having a plurality of connecting pieces 15c are used as constituent elements. Alternatively, the reel drum 16 is formed of a material having good light reflectivity, such as a transparent resin material. The index IDs (1Li, 1Ci, 1Ri) provided on the reels 1L, 1C, 1R are provided via three attachment portions 17 for engaging the bifurcated claws 17b with the claw holes 17a provided on the three spokes 14 of the reel drum 16. The angle at which the on-edge portion 18a and the off-edge portion 18b at the time of normal rotation are viewed is 180 degrees, a semicircular arc shape in which an on-period and an off-period occur exactly half a turn, and a light-shielding material such as a black resin material It consists of the band component 18 formed by the following.

  With the three-point support by the three attachment portions 17, the belt component 18 is well held in an arcuate shape equidistant from the center of the shaft SH, with both ends protruding and the center being pushed toward the center. The band member 18 passes through the gap GP of each index sensor IDs (11L, 11C, 11R) composed of a photosensor supported on the stationary member side. The band component 18 passes through the on-edge portion 18a that blocks the light of the gap GP and the passage of the off-edge portion 18b that allows the light to pass through again, appearing every half circle, and during one rotation, two reel displacement angles, that is, an on-edge corresponding angle and an off-edge The corresponding angle makes it possible to correct the number of excitation pulses supplied to the stepping motor SM. In the remarks column, the index sensor IDs are indicated by a simplified notation with the tip of the wedge facing the light blocking and passing position. Each index sensor IDs and each stepping motor SM is supported by a motor plate 19 that is one of the components of a reel box that is housed in the housing.

  With a 20-frame reel, for example, when the symbol number 0 starts to pass with respect to a reference position determined in the middle of the display window 80, the on-edge portion 18a reaches the index sensor IDs and the index sensor IDs are turned on from off. When the on-edge to be switched to is detected and the symbol of symbol number 10 shifted 180 degrees from symbol number 0 begins to pass, the off-edge portion 18b is separated from the index sensor IDs, and the index sensor IDs is switched from on to off. An off edge is detected. When an on-edge is detected, as a zero correction value for the total number of steps for one rotation, the symbol number 0 is stored in the symbol counter FGC of the current symbol passing through the reference position, and the symbol number is stored in the step counter SPC that manages the number of steps per frame. The initial step number 25 by descending order management (25-0) corresponding to the step number 26 of the 0th is stored by overwriting. When detecting the off-edge, as a 252 correction value that is half of the total number of steps for one rotation, the symbol number FGC is assigned the symbol number 10 and the step counter SPC is the initial step number 25 corresponding to the symbol number 10 step number 26. Store each by overwriting. The symbol counter FGC and the step counter SPC are provided on the RAM of the main controller MC for each reel 1L, 1C, 1R.

  Similarly, in the 21-frame reel, an on-edge is detected when the symbol number 0 starts to pass with respect to a reference position defined in the middle of the display window 80, and the symbol number 11 is displaced 180 degrees from the symbol number 0. The off-edge is detected when the middle of the symbol starts to pass. When detecting an on-edge, as a zero correction value for the number of steps for one rotation, symbol number 0 is assigned to symbol counter FGC, and initial step number 23 by descending order management corresponding to step number 24 of symbol number 0 is assigned to step counter SPC. Store each by overwriting. When off-edge is detected, the symbol counter FGC is overwritten with symbol number 11 and the step counter SPC is overwritten with the central step number 12 corresponding to the step number 24 of symbol number 11 as the 252 correction value which is half the number of steps for one rotation. To store each.

  Note that the reference position does not necessarily need to coincide with the effective line, and may be determined at the upper or lower stage in the display window 80 or may be determined outside the display window 80. If the reference position and the active line are different, stop the design to be stopped so that the symbol corresponding to the winning combination is displayed on the active line when the symbol to be stopped is stopped at the reference position. It will be. The index ID may be a band member of 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. Set to a suitable value. Moreover, it may replace with a strip | belt member and the system which detects an on-edge and an off-edge with the disk integrated with shaft SH may be used. Furthermore, two or more index sensors that arrange one index composed of small protrusions or the like at a plurality of locations may detect passage of the index sensor, thereby enabling two or more corrections during one rotation.

  As shown in FIG. 4, the control device CN incorporated in the gaming machine housing 8B transmits the main control device MC corresponding to the main board in the gaming machine rule and the main control device MC according to the unidirectional communication specification. Peripheral control device SC corresponding to the “peripheral board” referred to in the gaming machine rules for receiving information to be received. The one-way communication specification refers to a communication specification that satisfies “not capable of receiving a signal transmitted by a peripheral board” defined in the gaming machine rules for the main board.

  The main control device MC includes a main CPU, a ROM, and a RAM. In the input port I1, each index sensor 11L, 11C, 11R, each stop button 6L, 6C, 6R, the bet button 3, the settlement button 4, the start lever 5, the insertion medal sensor 21 provided downstream of the medal slot 2, game machine Each signal of the payout medal sensor 23 provided at the exit 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, the stepping motors 12L, 12C, 12R (SM) via the motor driver circuit Dr1, and the game via the LED driver circuit Dr2 The basic lamps 30, the medal blocker 22 for dropping medals inserted after the reel start via the solenoid driver circuit Dr3 to the medal tray 8G, the medal paying motor 24 of the medal paying device HP via the motor driver circuit Dr4, respectively. I have control.

  On the ROM of the main control device MC, for example, when the start lever 5 is operated while a predetermined number of multiplying medals are inserted, for example, the continuous action device RBB and the second type special combination for the first type special combination Special winning combination with the consecutive accessory actuating device CBB related to things, multiple winning roles (small roles) including push order small roles that can win medals, and multiple replaying roles that allow the next game to be performed without inserting new medals ( An internal lottery means K for executing an internal lottery for determining whether or not a predetermined combination is won is established. When indicated by the combination of “left symbol”-“middle symbol”-“right symbol” on the active line (middle stage), the RBB operates as “bar”-“bar”-“bar”, and the CBB is “replay”. ”-“ Bell ”-“ Bell ”is displayed, the re-playing role is operated by“ Replay ”-“ Replay ”-“ Replay ”, etc., and the small role is“ Bell ”-“ Bell ”-“ Bell ” ”Etc. to win a prize. In the internal lottery, when the start lever 5 is operated, a random number value extracted from, for example, a 2-byte counter that is updated at high speed on the RAM of the main controller MC is classified in association with a role within a range of 0 to 65535 that can be taken. The winning combination in the game is determined depending on which winning area it belongs to.

  Further, on the ROM of the main controller MC, the reels 1L, 1C, and 1R are accelerated to the forward rotation side after the start lever 5 is operated and after the minimum game interval of 4.1 seconds has elapsed since the start of the previous game. The rotating device control means V1 for controlling the rotating device referred to in the second part (3) b of the game machine rule Article 6 of the gaming machine rule to reach the steady rotational speed, and the corresponding stop button for each reel 1L, 1C, 1R Controls the rotation stop device referred to in Table 2 (3) C. Allowing the display of the combination of symbols corresponding to the winning combination determined by the internal drawing on the active line by individually stopping by the operation of 6L, 6C, 6R The reel control means V including the rotation stop device control means V2 is constructed.

  The reel rotation device control means V1 has a non-stationary rotation for each reel 1L, 1C, 1R under unsteady rotation, including when power is restored due to a power failure or the like before reaching steady rotation and under steady rotation. There is provided an index flag setting means V10 for turning on the set state when the index flag for turning off the set state is detected under steady rotation.

  Further, when the index ID is detected first after reaching the steady rotational speed from the unsteady rotational speed for each of the reels 1L, 1C, and 1R, the rotation rotating device control means V1 relates to the earliest detection. First correction means V11 that first corrects the number of steps of the excitation pulse of the stepping motor SM with a 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 First correction information storage means V12 for storing information for distinguishing the reel displacement angle from the initial value 0 by rewriting the correction point flag IPF from an initial value 0 to 1 corresponding to on-edge or 2 corresponding to off-edge, and after the initial correction Until the operation of at least the stop buttons 6L, 6C, 6R, the first time based on the storage of the initial correction information storage means V12 Second and subsequent correction means V13 for correcting the number of steps of the excitation pulse with a correction value corresponding to the one reel displacement angle when detecting the index ID at one reel displacement angle for correction, and after the initial correction, There are provided second and subsequent non-correction means V14 that do not correct the step number of the excitation pulse when detecting the index ID at another reel displacement angle not related to the initial correction based on the storage of the initial correction information storage means V12.

  Note that during the acceleration process by the rotating device control means V1, all the symbols on all reels 1L, 1C, 1R are replayed> winning (small) according to the winning combination determined by the internal drawing> Prioritization by role according to the order of special roles, and when the winning role is a winning role (small role), there are many types of combinations of number priority and symbols that preferentially draw high paying small roles with a large number of payouts. Stop candidate search data with priorities assigned in the role corresponding to the number priority that preferentially pulls the winning combination is initially created on the RAM, and prepared for stop control by the rotation stopping device control means V2.

  In the first stop by the rotation stop device control means V2, when the stop operation by the stop button is detected and the stop request flag is turned on, it is upstream of the current symbol of the symbol counter FGC that has already reached the reference position. 0th frame (immediate stop), 1st frame, 2nd frame, 3rd frame, 4th frame, in principle, the following 5 frames (for stopping one or more specific reels in the CBB such as the right reel 1R) Is the highest priority based on the stop candidate search data created during the acceleration process for the 0th frame (immediate stop) upstream of the current symbol of the symbol counter FGC and the 2nd frame of the first frame in principle) In addition to performing a logic operation to search for the highest symbol with the highest level, and if there are multiple top symbols, refer to the stop table defined in advance in the ROM so that To determine the only stop symbols high. Then, the timing when the determined stop symbol reaches the reference position, that is, the symbol number of the stop symbol determined by the symbol counter FGC is updated, and the value of the step counter SPC is updated to the initial number of steps by descending order management corresponding to the stop symbol. At this time, a stop pulse by all-phase excitation or the like is supplied to the reel stepping motor SM related to the first stop.

  When the first stop is completed, during the stop operation interval period until the next stop button operation can be accepted (for example, for about 200 ms), the display is not subject to display according to the display result of the first stop. For the symbol and / or the number of symbol combination types to be changed, the stop candidate search data of the unstopped reel is rewritten to prepare for the second and subsequent stops. In the second stop, a stop candidate that has been rewritten after the first stop for the following symbols such as 5 frames that continue in the upstream of the symbol that has reached the reference position when the stop request flag is turned on. Based on the search data, the same stop operation with the highest pull-in priority is determined by referring to the same logic operation or logic operation and stop table as described above, and the stop pulse is similarly applied when the determined stop symbol reaches the reference position. Supply.

  When the second stop is completed, during the stop operation interval period until the last stop button operation can be accepted (for example, for about 200 ms), the display of the first stop and the second stop is displayed. In order to prepare for the third stop, the stop candidate search data of the unstopped reel is rewritten with respect to the symbols that are not the target and / or the symbols that are not kicked to prevent the completion of the winning combination and cannot be stopped. In the third stop, the stop candidate rewritten after the second stop for the following symbols, such as the same five frames in principle, that continue upstream of the symbol that has reached the reference position when the stop request flag is turned on. Based on the search data, the same logic operation as described above or logic operation and reference to the stop table are used to determine and determine the only stop symbol that has the highest drawing priority and that does not complete the winning combination. Similarly, a stop pulse is supplied at the timing when the stop symbol reaches the reference position.

  Thus, the stop of all reels 1L, 1C, 1R is completed, and the result of one game is derived. After the first stop operation, the second stop operation, and the third stop operation, the first time based on the storage of the initial correction information storage means V12 during the slip period until the reel is stopped based on each stop operation. Even if the index ID is detected at one reel displacement angle related to the correction, the excitation pulse is provided on condition that the index flag is in the set state and the stop request flag for the reel stop operation is on. The stop process is performed without correcting the number of steps. This non-correction stop processing means V21 is provided in the rotation stop device control means V2.

  The operation of the non-correction stop processing means V21 is based not only on the stop request flag being turned on but also on the index flag being turned on, because the index flag that was once turned on after steady rotation was not turned off. This is to secure 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 initial correction is performed again by detecting the index related to the earliest detection after steady rotation. . In this case, the stop request flag that was once turned on before power interruption may be invalidated. However, if valid, stop control that is performed after the next interrupt after the index flag is turned on and the initial correction is made. It will be used for.

  On the ROM of the main controller MC, the medal payout means P for paying out a medal with a predetermined payout number if the game result is a win, and automatically inserting the medal for the next game in the same prescribed number if the game result is a re-game operation.

  As shown in FIG. 5, each stepping motor SM has a permanent magnet built-in rotor Rm 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 periphery of the magnetic pole. And a stator Sw wound with windings of phase, B phase, C phase (A bar phase (inverted phase of A)), D phase (B bar phase (inverted phase of B)), and one winding Excitation by 1-2 phase excitation in which a step of supplying a one-phase excitation pulse for turning on and a step of supplying a two-phase excitation pulse for turning on one winding and another adjacent winding are alternately repeated. A half step angle (one step angle by two-step update) is displaced by one step update of the pulse. Further, forward rotation and reverse rotation are made possible by changing the step update direction of the excitation pulse.

  Each stepping motor SM has a specification in which one step angle is about 1.43 degrees, an interruption time t for updating the excitation pulse by one step is 1.49 ms, and one rotation is made in 504 steps. Therefore, at the normal time, the reels 1L, 1C, and 1R are rotated once for 1.49 ms × 504≈751 ms for about 79.9 rotations per minute for both the 20-frame reel and the 21-frame reel. The stepping motor SM rotates exactly once by 504 step updates at the time of steady rotation unless a so-called step 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, and about 35.8 ms for a 21-frame reel. “((190 ÷ 37.6) −1) integer solution = 4 frames, ((190 ÷ 35.8) −1) integer solution = 4 frames is the maximum number of sliding frames allowed. .

  As shown in the stop sequence of [b], the stop pulse for stopping each stepping motor SM is applied to the A phase, B phase, C phase, and D phase windings for a predetermined time (for example, 201.15 ms corresponding to 135 interrupts). ) All-phase excitation pulses that are turned on are used. Since the excitation pulse at the time of the first correction based on the detection of the first index ID is one-phase excitation and the number of steps of one symbol is an even number, the step update for each symbol starts with one-phase excitation and ends with two-phase excitation. In principle, the excitation pulse immediately before supplying the all-phase excitation pulse is two-phase excitation. When an all-phase excitation pulse is supplied next to the two-phase excitation, the rotor Rm of the stepping motor SM is displaced by more than 1/2 angle, and the physical relationship with the stator Sm is more stable than the two-phase excitation position. Stops at the position corresponding to the phase excitation position. Depending on the inertia, there may be a case where the robot slides and stops for a maximum of 8 steps, but also 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 clean stop as a whole can be performed. After supplying a stop pulse by all-phase excitation for a predetermined time, excitation release is performed to turn off all of the A-phase, B-phase, C-phase, and D-phase windings. The stop pulse itself may be three-phase excitation or two-phase excitation for a predetermined time instead of all-phase excitation.

  In the acceleration process, as shown in the acceleration sequence [c], excitation is started from the two-phase excitation pulse pattern immediately before the application of the previous all-phase excitation pulse, and the first 35 interruption time (35 t = 52.15 ms) is long. On-phase two-phase excitation, 1-subtraction result of the sequence counter that manages this on-time (subtraction result for each interrupt) becomes 0, and one-phase excitation for five interrupt times at the next step update. The on-time is gradually shortened, such as two-phase excitation with interruption time, two-phase excitation with interruption time, two-phase excitation with interruption time, etc., and a steady rotational speed is reached after about 134 ms. For all reels 1L, 1C, 1R, after reaching steady rotation, the first correction is made based on the detection of the earliest index ID, and then the built-in LEDs 61, 62, 63 of each stop button 6L, 6C, 6R are turned on to stop. A stop operation by the buttons 6L, 6C, 6R can be accepted. The determination that the steady rotation has been reached may be made after securing a predetermined stop prohibition period of 0 to several tens of ms, for example, 50 ms after the elapse of about 134 ms required for the acceleration process.

  FIG. 6 shows a 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 for managing 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 (transient state until reaching the stopped state). Confirm (step s1, hereinafter referred to as s + step number). If it is in a stopped state, nothing is done and the process ends immediately (YES in s2). The acceleration state that becomes YES in s3 is set after the start lever 5 is operated and after 4.1 seconds of the minimum game interval has elapsed since the start of the previous game. In the acceleration process, every time the result of subtraction of 1 in the sequence counter becomes 0 (YES in s4), the excitation pulse pattern of the acceleration sequence in FIG. 5 [c] is set in order (s5). NO in s6), the number of interrupts corresponding to the ON time of the set excitation pulse pattern is set in the sequence counter (s7). When the acceleration sequence ends (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).

  When a steady rotation state is reached (YES in s10), one-phase excitation pattern or two-phase excitation pattern is alternately set for each interrupt (s11), and this time two-phase excitation (next one-phase excitation) is performed (in 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 been detected yet (NO in s13), the rotation error due to the deviation from the upper limit in which the edge of the index ID is not detected for a long 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), if the step counter SPC for managing 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 decremented 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 is turned off when the index flag is not yet turned on (NO in s19). In the case of detection of an on-edge that changes from ON to ON (YES in s20), when the correction point flag IPF is still the initial value 0 (YES in s21), after reconfirming whether or not it is in the steady rotation state (in S22) (YES), “1” is set in the correction point flag IPF to make the initial correction at the on-edge corresponding angle (S23), the index flag is turned from OFF to ON (S24), and the initial correction is performed by the on-edge correction (S25). . After the initial correction, based on the correction point flag IPF = 1 (YES in S26), the second and subsequent corrections are performed by on-edge correction (S25). When the initial correction is not the on-edge correction but the off-edge correction, even if the on-edge is detected, the 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 a zero correction value for the total number of steps for one rotation, for a 20-frame reel, the symbol number 0 is stored in the symbol counter FGC and the number of steps 26 in the symbol number 0 is stored in the step counter SPC. In the 21-frame reel, the symbol number 0 is stored in the symbol counter FGC, and the initial step number 23 corresponding to the step number 24 in symbol number 0 is overwritten in the 21-frame reel. Store each. In this way, the initial correction is performed by the on-edge detection related to the earliest detection at the on-edge corresponding angle. Even if an off-edge is detected at the 254th step, the on-period is 254 steps longer than the original 252 steps, the actual off-edge portion 18b is longer than ideal, and no correction is made here. From the second time on, the on-edge correction is performed once per rotation only by detecting the same on-edge as in 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), the index flag is not turned on (NO in s19). If the index sensor IDs has been detected as an off-edge that changes from on to off (NO in s20), when the correction point flag IPF is still at the initial value 0 (YES in s27), reconfirmation of whether or not it is in a steady rotation state After that (YES in s28), the correction point flag IPF is set to “2” for initial correction at the off-edge corresponding angle (s29), the index flag is turned from OFF to ON (s30), and the initial correction is performed 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 off-edge correction (s31). When the initial correction is not the off-edge correction but the on-edge correction, even if the off-edge is detected, the 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, as a 252 correction value that is half of the total number of steps for one rotation, on the 20-frame reel, the symbol number 10 is stored in the symbol counter FGC and the symbol number 10 is stored in the step counter SPC. The initial step number 25 corresponding to Equation 26 is stored by overwriting, and in the 21-frame reel, the symbol number 11 is stored in the symbol counter FGC, and the central step number 12 of symbol number 11 is stored in the step counter SPC. In this way, the initial correction is performed by off-edge detection related to the earliest detection at the off-edge corresponding angle. The off period is 250 steps 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, no correction is made here. From the second time on, off-edge correction is performed once per rotation only by detecting the same off-edge as in the first correction.

  In the steady rotation process of FIG. 6, when the index ID edge is detected and the index flag is on (YES in s19), the index ID edge is detected within a short period exceeding the predetermined lower limit. It is determined whether or not there is a rotation error (s33). If there is no rotation error (NO in s33), it is reconfirmed that the index flag is on (s34) and the stop request flag is turned on immediately (s35). When the index flag is on and the stop request flag is on (YES in s34 and YES in s35), the correction by detecting the edge of the index ID is not performed, and the step counter SPC is updated (s15 to s18). Then, stop processing is performed based on the stop request flag being turned on (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 to be the stop symbol and the current symbol = stop symbol (YES in s37), the index flag is turned ON again. After confirming (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). As an exception, regarding the stop of the right reel 1R in the CBB with the 20-frame reel, if the symbol of the first frame two above the symbol of the symbol counter when the stop request flag is turned on is drawn, the restriction is limited. If the time exceeds 75 ms, the symbol counter symbol when the stop request flag is turned on is immediately stopped, or the symbol in the 0th frame above this symbol is stopped. .

  In the stopping process in which the motor state is in the stopping state, the all-phase excitation time is subtracted (s43), the result becomes 0 (YES in s44), the excitation is released (s45), and the motor is released. The state is set to a stop state (s46). Thus, the rotation and stop of each reel 1L, 1C, 1R are controlled. If a rotation error due to an upper limit deviation or a lower limit deviation is detected, the motor state is set to the acceleration state (s47), and the process is repeated from the acceleration process. Rotation error detection due to deviation from the upper limit (s14) is performed during two-phase excitation, rotation error detection due to deviation from the lower limit (s33) is performed during one-phase excitation, and the number of counter bits for determining the error Saving.

  In the above embodiment, a 20-frame reel or a 21-frame reel is shown. However, the number of symbols of one reel is 16 frames, and there are few symbols corresponding to symbol numbers 0, 4, 8, and 12 that are multiples of 4 including 0. Allocating the even number of steps 30 and assigning the larger even number of steps 32 to each of the other symbols 1, 2, 3, 5, 6, 7, 9, 10, 11, 13, 14, 15. You may apply to the 16 frame reel which made the maximum number of sliding frames 3 frames. 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 is determined by the main control device MC, but may be determined by the peripheral control device SC.
