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.

  Patent Document 1 describes that the number of steps of an excitation pulse of a stepping motor is corrected by detecting an index (paragraph 0037 and the like). Further, in paragraph 0228, “In FIG. 17, the left reel 31 shows an example of the acceleration state of the motor 32 when there is no delay time. First, 20 interrupts (20 × 2.235 = 44.7 ms). ) 1 step drive, next 16 interrupts, 1 step drive, then 12 interrupts, 1 step drive, ... 1 step drive in less time, and finally 1 interrupt (2.235 ms )), One step drive (constant speed state) ”is shown, and FIG. 17 shows that the number of 6 steps is updated from the first 20 interrupt drive to the last 1 interrupt drive. A predetermined acceleration sequence for reaching a steady rotation after passing through a relatively small number of update steps (6 in this document specification, which is less than 16 steps corresponding to one symbol (paragraph 0197)). It has been described.

JP 2014-50570 A

  However, the stepping motor rotates while repeating acceleration and deceleration slightly during steady rotation as its characteristic, and immediately after the acceleration sequence is over, it is in an unstable period where the vibration amplitude due to acceleration and deceleration is large. Therefore, if the number of steps is corrected by detecting the index at this time, correct correction may not be performed. If the reel is further rotated beyond “1 rotation ÷ number of detected indexes”, the next correction corrects the correct correction. However, if the stop button is pressed immediately after the unstable index correction, the deviation from the original normal position will occur. There is a high risk that the design will stop at a certain position and a step difference from the stop design of the reel that will be stopped after that will result in an unsightly display appearance. In addition, if the stop operation is made possible in a short time after the acceleration sequence is completed, for example, a characteristic symbol such as a seven symbol (7 symbols) is stopped on the upper stage of the display window. There is also a possibility that the symbol can be stopped immediately at the lower stage or the like, and the stopping operation becomes too simple and the gameability is impaired.

  The problem of the present invention is that even if the stop operation is performed at an early stage from the start of the reel, the pattern deviation can be reduced as much as possible, a beautiful output with few steps can be displayed, and the top can be stopped only by moving in the display window. This is to provide a gaming machine that can prevent an extremely small displacement stop when the symbol is displayed again below.

The reference numerals of the drawings are illustrated in parentheses for illustration.
With reels (1L, 1C, 1R) that have multiple frames and are rotated by step update of excitation pulses supplied to the stepping motor (SM),
It is premised on a gaming machine in which the number of steps of the excitation pulse can be corrected when an index (ID) at a specific reel displacement angle detected during the rotation of the reel is detected.

In the above,
The number of excitation pulse update steps (As) in the acceleration sequence for causing the stepping motor (SM) to reach the steady rotation state from the stopped state, and the number of excitation pulse update steps in the stop prohibition timer section secured after the acceleration sequence. The sum with (Ts)
The index (ID) from the initial value (23) of the number of steps (24) assigned to a specific symbol (symbol number 18, 8) located at a predetermined reference position (for example, the upper stage) corresponding to the specific reel displacement angle. Until the number of steps (23) that needs to be updated until the detection is detected, from the state in which the symbol one frame ahead of the specific symbol is stopped at the predetermined reference position to immediately before the acceleration sequence is updated to the specific symbol. Is set to a value exceeding the value obtained by adding the number of steps (26) requiring updating.

  As a result, even if the acceleration sequence starts from the state where the symbol ahead of the specific symbol is stopped at the predetermined reference position, the number of steps for updating the excitation pulse, which is the sum of the acceleration sequence and the stop prohibition timer section, is one frame ahead. Since the number of steps that need to be updated from the initial value of the number of steps assigned to the specific symbol to the specific symbol and the number of steps that need to be updated before detecting the index exceeds the number of steps Correction by index detection is not performed, and correction is performed at the time of detection of an index after the next time when update has progressed beyond at least two frames. For this reason, it is possible to prevent correction at a position deviated from an appropriate position by index detection at an unstable time as a steady rotation state. Therefore, the pattern deviation can be reduced as much as possible, and a beautiful appearance with few steps can be displayed. Moreover, since the correction is made by detecting the index after the update has progressed beyond at least 2 frames, an extremely small displacement in which the symbol that has been stopped up only by moving within the display window is displayed again below. Stops can also be prevented.

Each of the reels 1L, 1C, and 1R is a 20-frame reel that arranges all 20-frame symbols.

  For driving each reel 1L, 1C, 1R, a stepping motor having a specification in which one step angle for driving a standard 21-frame reel is about 1.43 degrees and rotates once in 504 steps by 1-2 phase excitation is used. . In the case of 21-frame reels, an equal number of steps of 504/21 = 24 steps can be assigned per symbol, but in the case of 20-frame reels, 504/20 = 25.2 does not result in an integer solution, so an uneven number of steps is assigned. ing. Symbol number 1,3,6,8,11,13,16 in which the remainder of the integer solution obtained by dividing 26 with the larger number of steps and 24 with the smaller number of steps and dividing symbol numbers 0 to 19 by 5 is odd. Assign the lesser 24 steps to 18 symbols, and assign the more 26 steps to the other symbols 0, 2, 4, 5, 7, 9, 10, 12, 14, 15, 17, 19 ing.

  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.

When the number of steps becomes 1, the on-edge portion 18a reaches the index sensor IDs, and the on-edge where the index sensor IDs switches from off to on is detected, and the on-edge correction is performed by detecting the on-edge. Similarly, the bar symbol of symbol number 8 which is displaced 180 degrees from symbol number 18 reaches the end of passage with respect to the predetermined reference position defined in the upper stage, and counts down from the initial value 23 of step number 24 assigned to this symbol to 0 When the number of steps in descending order management to be 1, the off edge portion 18b is separated from the index sensor IDs, and the off edge where the index sensor IDs switches from on to off is to be detected, and off edge correction is performed by detecting the off edge. The

  When an on-edge is detected, 18 of the symbol number 18 is assigned to the symbol counter FGC that manages the symbol number of the symbol that is passing the predetermined reference position, and 1 is assigned to the step counter SPC that manages the number of steps of the symbol that is passing the predetermined reference position. Is stored by overwriting. The symbol number of the symbol counter FGC just before the detection of the on-edge and the number of steps of the step counter SPC are not the symbol symbol FGC = 18 which should be originally, and the step counter SPC = 2 (2 immediately before 1). However, correction (on-edge correction) is performed by storing 18 in the symbol counter FGC and 1 in the step counter SPC by detecting the on-edge. The symbol counter FGC and the step counter SPC are provided on the RWM of the main controller MC for each reel 1L, 1C, 1R.

  When off-edge is detected, symbol number 8 is stored in symbol counter FGC and 1 is stored in step counter SPC by overwriting. The symbol number of the symbol counter FGC immediately before the detection of the off edge and the number of steps of the step counter SPC are not the symbol counter FGC = 8 and the step counter SPC = 2 (2 immediately before 1), but are temporarily shifted. However, correction (off-edge correction) is performed by storing 8 in the symbol counter FGC and 1 in the step counter SPC by detecting the off-edge. After the initial correction by detecting the on-edge or off-edge is made for each reel, the operation of the stop buttons 6L, 6C, 6R can be accepted.

  The predetermined reference position may or may not match the effective line, and may be determined at the middle or lower level in the display window 80 or may be determined outside the display window 80. If the predetermined reference position and the active line are different, stop the symbol to be stopped at the predetermined reference position so that the symbol corresponding to the winning combination is displayed on the effective line. Will be determined. In addition, if the index can be detected at least once for each rotation of the reel at any fixed rotation angle, the index detects a protrusion integrated with the reel with a sensor, a stepping motor Any type may be used, such as a sensor that detects a notch or the like of a disk integrated with the shaft of the disk.

Then, the timing at which the determined stop symbol reaches the upper appropriate position as the predetermined reference position, that is, the symbol number of the stop symbol is updated by the symbol counter FGC and the value of the step counter SPC is updated in descending order management corresponding to the stop symbol. When the number of steps is updated to the initial number of steps (25 for the number of 26 steps and 23 for the number of 24 steps), 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, the search for candidate candidates rewritten after the first stop is performed on the following five consecutive symbols that are continuously upstream of the symbol that is being passed by the symbol counter FGC when the stop request flag is turned on. Based on the data, determine the only stop symbol with the highest pull-in priority by referring to the same logic operation or logic operation and stop table as above, and stop at the timing when the determined stop symbol reaches the appropriate position in the upper stage. Supply pulses.

  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, when the stop request flag is turned on, a stop candidate that is rewritten after the second stop for the following symbols such as the same five frames that are continuously upstream of the symbol that is being passed by the symbol counter FGC. 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 upper appropriate position.

The average time required for the symbol to move by one frame is about 37.6 ms, and the prescribed time from the reel stop operation to the stop at the normal time in the gaming machine rules is “within 190 ms” ((190 ÷ 37. 6) The integer solution of -1) = 4 frames is the maximum number of sliding frames allowed. Forward rotation and reverse rotation are made possible by changing the step update direction of the excitation pulse.

  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 correction based on the index ID detection is one-phase excitation (two-phase excitation at the next interrupt) and the number of steps in one symbol is an even number, step updating for each symbol starts with one-phase excitation. It ends with two-phase excitation. All step excitation pulses are supplied when the step counter SPC = initial value (25 step symbol is 25, 24 step symbol is 23), and the excitation pulse immediately before the all phase excitation pulse supply is two-phase excitation. Become. When the all-phase excitation pulse is supplied next to the two-phase excitation, the rotor Rm of the stepping motor SM is often displaced by more than a half angle, so that the physical relationship with the stator Sm is more than the two-phase excitation position. Is stopped at a position corresponding to a stable 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. Depending on the inertia, it may slip and stop for a maximum of about 8 steps, but in this case as well, it stops at a position corresponding to the one-phase excitation position at least when excitation is released later. 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.

  As shown in [c] acceleration sequence in FIG. 6, in the acceleration process, excitation is started from the two-phase excitation pulse pattern immediately before the application of the previous all-phase excitation pulse, and initially 42 interruption time (42t = 62.58 ms). Two-phase excitation with a long ON time, and the next step update when the 1 subtraction result (subtraction result for each interrupt) of the sequence counter managing this ON time becomes 0, the 9 interrupt time (9t = 13.41 ms) ) 1-phase excitation, then 2-phase excitation for 11 interruption times (11t = 16.39 ms), 1-phase excitation for 1 interruption time (t = 1.49 ms), 2-phase excitation for 4 interruption times (4 t = 5.96 ms) 1-phase excitation for 1 interrupt time (t = 1.49 ms) 2-phase excitation for 2 interrupt times (2t = 2.98 ms) 1-phase excitation for 1 interrupt time (t = 1) .49ms), the on-time was gradually shortened, and the 8-step update progressed To reach a steady rotation speed after 105.79ms lapse. In the interrupt process (1 interrupt time) at the ninth step, the motor control state managed by the main controller MC is changed from the acceleration state to the steady rotation state. After changing to the steady rotation state, the stop operation can be accepted after the earliest on-edge correction or off-edge correction through the time-up in the stop prohibition timer section to be secured subsequently.

  After the start of the acceleration sequence, rotation is performed with the vibration characteristics shown in the actual measurement data example in the remarks column. The actual measurement data is a monitor result on an oscilloscope in which the speed at the time of acceleration of each reel 1L, 1C, 1R is measured with a laser speedometer, and the horizontal axis is replaced with a time axis and the vertical axis is replaced with a voltage axis corresponding to speed. Each of the stepping motors 12L, 12C, 12R (SM) has a vibration characteristic that rotates while repeating acceleration and deceleration, the voltage is on the positive side (+ side), and the upward slope is in the normal rotation side acceleration range. The voltage is positive (+ side) and the downward slope is in the forward deceleration region, the voltage is negative (−) and the upward slope is in the reverse deceleration region, and the voltage is negative ( The negative slope is in the acceleration region on the reverse side. After the stop prohibition timer period has elapsed (after the time is up), vibration is relatively suppressed and further reduced with the passage of time.

  FIG. 7 shows a motor control process for each stepping motor SM of each reel 1L, 1C, 1R at every interrupt time of 1.49 ms in the main controller MC. First, a motor state flag provided on the RWM 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). If it is in an acceleration state, the process proceeds to acceleration processing (s3). The acceleration state is set after the start lever 5 is operated and after a minimum game interval of 4.1 seconds has elapsed from the start of the previous game. If it is a steady rotation state, the routine proceeds to a steady rotation process (s4). Other than these, the process proceeds to the stop process (NO in s4).

  In the acceleration process, every time the result of subtraction of 1 in the sequence counter becomes 0 (YES in s5), the excitation pulse pattern of the acceleration sequence in FIG. 6 is sequentially set (s6), and until the acceleration sequence is completed (NO in s7) ) Set the number of interrupts corresponding to the ON time of the set excitation pulse pattern in the sequence counter and finish the motor control process (s8). When the acceleration sequence ends (YES in s7), the motor state is set to the steady rotation state, and the motor control process is ended (s9).

  In the process during steady rotation, a one-phase excitation pattern or a two-phase excitation pattern is set for each interrupt (s10), and a symbol information update process for updating the step counter SPC and the symbol counter FGC step by step (s11). Subsequently, it is determined whether the stop prohibition timer has expired (s12). If the stop prohibition section is before the time expires, the motor control process is terminated.

  When an on-edge is detected after waiting for index correction after time-up (s13), it is determined whether or not there is a rotation error due to a 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 ( If there is no error, symbol information initialization processing is performed by on-edge correction in which the symbol counter FGC is set to 18 and the step counter SPC is set to 1 (s15). On the other hand, when an off-edge is detected (s16), the presence / absence of a rotation error due to deviation from the lower limit is also determined (s17). If there is no error, the design counter FGC is set to 8 and the step counter SPC is set to 1 by off-edge correction. Information initialization processing is performed (s18).

  If neither on-edge nor off-edge is detected, it is determined whether or not there is a rotation error due to an upper limit deviation in which an edge of the index ID is not detected for a long time exceeding the predetermined upper limit (s19). As in the case of an error (YES in s14 or s17), in order to start over from the acceleration process, the motor state is set to the acceleration state and the motor control process is ended (S20).

  After the on-edge correction in s15 or after the off-edge correction in s18 or after determining no error in s19, it is determined whether or not the stop request flag set by pressing the stop button 6L, 6C, 6R in the acceptable state is ON (s21). When the stop request flag is on (YES in s21), the current symbol of the symbol counter FGC is updated to the symbol determined as the stopped symbol, and the current symbol = stop symbol, step counter SPC = initial value of the number of steps (25 or 23) (YES in s22), the stop request flag is reset (s23), the all-phase excitation pulse is set (s24), the all-phase excitation time is set (s25), and the motor state is stopped. To complete the motor control process (s26). When the stop request flag is OFF (NO in s21), or when the current symbol is not the stop symbol (NO in s22), the motor control process is finished while continuing the steady rotation state.

  In the stop process, the all-phase excitation time is subtracted (s27), the result is 0 and the time is up (YES in s28), the excitation is released (s29), and the motor state is set to the stop state. The motor control process is finished (s30). If the all-phase excitation time is before the time is up (NO in s28), the motor control process is terminated while maintaining the stopped state.

  As shown in FIG. 8, a watermelon 1 with a symbol number 18 that is a specific symbol corresponding to an on-edge, a white 7 symbol with a symbol number 19 that is a symbol one symbol ahead of the symbol stops at the upper stage of the display window 80 at a predetermined reference position. When the acceleration sequence is started from this state, the acceleration state is changed to the steady rotation state by the symbol counter FGC = 19 and the step counter SPC = 17. The update step number As in the acceleration sequence including the one-step update of one interruption time required for the change from the acceleration state to the steady rotation state is nine steps.

  The stop prohibit timer starts counting from the symbol counter FGC = 19 and the step counter SPC = 16, resulting in a stop prohibit timer section of 41 interrupt time = 60.09 ms. Since one step is updated by one interrupt, the number of update steps Ts in the stop prohibition timer section is 41 steps. After updating from one frame ahead symbol to specific symbol, FGC = 18, SPC = 1, the on-edge correction scheduled timing is reached, but the update step number As = 9 in the acceleration sequence and the update step number in the stop prohibition timer section The excitation pulse update step number As + Ts = 50, which is the sum of Ts = 41, is an initial value of the step number 26 that needs to be updated immediately before being updated from one frame ahead symbol to the specific symbol and the step number 24 allocated to the specific symbol. Since the number of steps 26 + 23 = 49, which is the sum of the number of steps 23 to be updated from S23 to SPC = 1 of the scheduled on-edge correction timing, exceeds 26 and the stop prohibit timer has not timed out, on-edge correction is not performed.

  When the symbol counter FGC = 18 and the step counter SPC = 0, the stop prohibit timer expires, and an index correction waiting period for waiting for the next scheduled correction timing, that is, the off-edge correction scheduled timing. About half a round, the off-edge correction scheduled timing of the symbol counter FGC = 8 and the step counter SPC = 1 is reached. When the off-edge is actually detected, the off-edge correction for setting FGC = 8 and SPC = 1 is performed, and FGC = 8, SPC Stop operation becomes possible after = 0. When the stop operation of the stop button 6L is detected at the timing of FGC = 8 and SPC = 0, the shortest stop symbol is the replay symbol of symbol number 7.

  Thus, when the acceleration sequence is started from the state in which the white 7 symbol of symbol number 19 is stopped in the upper stage, correction is not performed at the first on-edge correction timing that arrives in an extremely short time, and the upper, middle, and Since the symbols that have stopped in the lower stage are displaced outside the frame of the display window 80 and are corrected by the off-edge detection performed in a situation where the vibration of the reels is suppressed, the pattern deviation can be reduced, and there is a beautiful output with few steps. In addition to displaying the eyes, it is possible to prevent an extremely small displacement stop where the upper symbol is redisplayed in the lower portion only by moving within the display window 80.

  As shown in FIG. 9, the watermelon 1 symbol of symbol number 0 which is a symbol two symbols ahead of the symbol of watermelon 1 symbol which is a specific symbol corresponding to on-edge is stopped at the upper stage of the display window 80 which is a predetermined reference position. When the acceleration sequence is started from this state, the acceleration state is changed to the steady rotation state by the symbol counter FGC = 0 and the step counter SPC = 17. Similarly, the update step number As in the acceleration sequence is 9 steps including the one-step update of one interruption time required for the change from the acceleration state to the steady rotation state.

  The stop prohibit timer starts counting from the symbol counter FGC = 0 and the step counter SPC = 16, resulting in a stop prohibit timer section of 41 interrupt time = 60.09 ms. When the symbol counter FGC = 19 and the step counter SPC = 2, the stop prohibit timer expires and an index correction waiting period is reached, the on-edge correction scheduled timing of the symbol counter FGC = 18 and the step counter SPC = 1 arrives, and the on-edge Is detected, on-edge correction is performed to set FGC = 18 and SPC = 1, and a stop operation becomes possible after FGC = 18 and SPC = 0. When the stop operation of the stop button 6L is detected at the timing of FGC = 18 and SPC = 0, the shortest stop symbol is the replay symbol of symbol number 17.

  In this way, when the acceleration sequence is started from the state in which the design number 0 of the watermelon 1 is stopped in the upper stage, the stop operation can be performed earliest, but even in this case, the display window 80 stops in the upper, middle and lower stages. Since the on-edge correction is performed under the condition that the pattern that has been moved is displaced outside the frame of the display window 80 and the vibration of the reel is suppressed to some extent, it is possible to substantially reduce the pattern deviation and display a beautiful appearance with few steps. Further, it is possible to prevent an extremely small displacement stop in which a symbol having the same symbol number in the upper stage is re-displayed in the lower stage only by moving in the display window 80.

  As shown in FIG. 10, the cherry symbol of symbol number 9 which is the symbol one symbol ahead of the bar symbol of symbol number 8 which is a specific symbol corresponding to the off-edge is stopped at the upper stage of the display window 80 which is a predetermined reference position. When the acceleration sequence is started, the correction is not performed at the first scheduled off-edge correction timing, but is corrected when the on-edge is actually detected at the next scheduled on-edge correction timing. The relationship between the symbols in FIG. 8 differs from that in the half circle, and the same effects as in the case of FIG. 8 are obtained except that the correction is made at the on-edge instead of the off-edge.

  As shown in FIG. 11, the watermelon 2 symbol of symbol number 10 which is the symbol two symbols ahead of the symbol symbol of symbol number 8 which is a specific symbol corresponding to off-edge has stopped at the upper stage of the display window 80 which is a predetermined reference position. When the acceleration sequence is started from the state, the stop operation can be performed earliest as in the case of FIG. 9. In this case, however, the symbols stopped in the upper, middle, and lower stages of the display window 80 are displayed. 9 and the off-edge correction is performed under the condition that the vibration of the reel is suppressed to some extent, and the same effect as in the case of FIG. 9 is obtained.

  In the above embodiment, the number of steps assigned to the specific symbol is 24, and the number of steps that need to be updated until the index is detected from the initial value is 23. However, the number of steps assigned to the specific symbol is 26, and the initial value is The number of steps that need to be updated before detecting the index may be set to 25. In this case, Ts = 43 and As + Ts = 52 may be set. In the above embodiment, the left reel 1L is shown, but the same applies to the middle reel 1C or the right reel 1R.
