  Here, “a plurality of rotating reels (40) having a plurality of symbols on the surface and a predetermined number of symbols among the plurality of symbols attached to each rotating reel (40) are displayed in a visible manner. And a display unit (72). The rotation of each rotary reel (40) starts according to the start operation by the player, and the rotation of each rotary reel (40) stops according to the stop operation by the player. When a predetermined symbol arrangement is displayed on the display unit (72) when the rotating reel (40) of the player is stopped, the gaming machine (10) that gives a predetermined profit to the player is, for example, Three rotating reels (40) with a plurality of symbols attached, and a symbol display window (72) for displaying three of the plurality of symbols attached to each rotating reel (40). A start switch (50) for starting rotation of each rotary reel (40), and each rotary reel (40 ) And a stop switch (60) for stopping rotation. When the start switch (50) is operated, the rotation of each rotary reel (40) starts, and when the stop switch (60) is operated, each rotation reel When the rotation of (40) stops and the rotation of all the rotating reels (40) is stopped, if a predetermined symbol arrangement is displayed in the symbol display window (72), a predetermined profit is given to the player. There is a slot machine (10) that is given. In addition, the gaming machine (10) includes a video game in which an image of the slot machine is displayed on a liquid crystal display or the like, and a player can play a game in the displayed slot machine by operating a controller or the like. In the present invention, the profit given to the player is determined in advance according to the displayed pattern arrangement.

“Starting operation” means operating the operating device (50) for starting the rotation of each rotating reel (40). For example, in the slot machine (10), the player operates the start switch (50). Say. In addition, for example, in a video game, the start operation includes pressing a predetermined button of the controller in order to start rotation of the stopped rotating reel displayed on the liquid crystal display or the like.
“Stop operation” refers to operating the operating device (60) for stopping the rotation of each rotating reel (40). For example, in the slot machine (10), the player operates the stop switch (60). Say. In addition, for example, in a video game, the stop operation includes pressing a predetermined button of the controller in order to stop the rotating reel displayed on the liquid crystal display or the like.
“Accelerated rotation” means that the rotating reel (40) rotates at a gradually increasing rotational speed. For example, in the slot machine (10), when the start operation is performed by the player, the rotation of the rotary reel (40) starts. At this time, the rotating reel (40) gradually increases in speed until reaching a certain speed. This rotation that gradually increases until reaching a certain speed is called acceleration rotation. Also, for example, in a video game, the rotating reel of the slot machine accelerates, and the rotating reel rotates at an increased speed by displaying on the liquid crystal display an image that appears to gradually increase the rotating speed. Displaying it so that it can be seen is also included in accelerated rotation.
“Constant rotation” means that the rotating reel (40) rotates at a constant speed. For example, in the slot machine (10), when the rotating reel (40) in which acceleration rotation is performed reaches a constant speed, the speed is not increased and the reel (40) rotates at a constant speed. The rotation that rotates at a constant speed after reaching the constant speed is called constant speed rotation. In addition, for example, in a video game, a video image that appears as if the rotating reel of the slot machine is rotating at a constant speed is displayed on a liquid crystal display so that the rotating reel appears to rotate at a constant speed. Displaying is also included in the constant speed rotation.

  The “role lottery means (110)” performs a lottery to determine whether or not each rotary reel (40) can be stopped so that a predetermined symbol arrangement is displayed on the display unit (72). It is meant for. That is, the lottery result of the winning lottery means (110) indicates that it is possible to stop each rotating reel (40) so that a predetermined symbol arrangement is displayed on the display unit (72), and the player's If the timing of the stop operation is correct, a predetermined symbol arrangement is displayed on the display unit (72). If the lottery result of the winning lottery means (110) indicates that the predetermined symbol arrangement is not displayed on the display unit (72), the predetermined symbol arrangement is displayed on the display unit (72 ) Is not displayed.

  The “rotational position detecting means (130)” is for detecting the rotational position of each rotary reel (40). The rotation position indicates how much the rotation reel (40) is at a position rotated compared to the reference position. For example, in the slot machine (10), the rotation angle from the reference position of each rotary reel (40), the number of times a pulse is output from the time when each rotary reel (40) is at the reference position, the elapsed time, etc. are detected. By doing so, the rotational position of each rotary reel (40) is detected. For example, when displaying an image that appears as if the rotating reel of the slot machine is rotating in a video game or the like on a liquid crystal display or the like, by detecting the number of times a signal from the start of rotation is detected. The rotational position of the displayed rotating reel is detected.

  The “stop control means (140)” means each rotation based on the lottery result of the role lottery means (110) and the detection result of the rotational position detection means (130) when the stop operation is performed by the player. This is for controlling stop of the reel (40). Stop control means that when a stop operation is performed by a player, the rotating reel (40) is immediately stopped, or the rotating reel (40) is slightly rotated and then stopped. Controlling the stop of the rotating reel (40) so that the arrangement is displayed on the display section (72) or the predetermined symbol arrangement is not displayed on the display section (72). For example, the lottery result of the winning lottery means (110) indicates that each rotating reel (40) can be stopped so that a predetermined symbol arrangement is displayed on the display unit (72). If the rotation position of the rotary reel (40) when the stop operation is performed is a rotation position at which the predetermined symbol arrangement can be displayed on the display unit (72), the predetermined symbol arrangement is displayed on the display unit (72 ) Stop the rotating reel (40) as it is displayed. In other cases, for example, the lottery result of the winning lottery means (110) indicates that the predetermined symbol arrangement is not displayed on the display unit (72), or when the player performs a stop operation ( If the rotation position of 40) is not a rotation position at which the predetermined symbol arrangement can be displayed on the display unit (72), the rotation is performed so that the predetermined symbol arrangement is not displayed on the display unit (72). Stop the rotating reel (40) inside.

  The “winning determination means (150)” is for determining whether or not a predetermined symbol arrangement is displayed on the display section (72) when all the rotating reels (40) are stopped. . That is, based on the detection result of the rotational position detecting means (130), it is detected whether each rotating reel (40) is stopped so that a predetermined symbol arrangement is displayed on the display unit (72). It is determined whether or not the array is displayed on the display unit (72). For example, if all the rotating reels (40) are stopped at the stop position where three symbols “7” are arranged on the display unit (72) when all the rotating reels (40) are stopped, It is determined that one of the symbol arrays “777 symbol array” is displayed on the display unit (72).

The “automatic stop control means (160)” is for performing stop control of each rotating reel (40) that is rotating even if a player does not perform a stop operation when a predetermined condition is satisfied. is there. For example, when a stop operation is not performed by the player even if a certain time has elapsed after the start operation by the player, or when there is a stop operation by the player even if there is no stop operation by the player Similarly, the rotating reel (40) is stopped.
“Similar to the case where the player performs a stop operation” means that the lottery result of the winning lottery means (110) is displayed on each rotary reel (40) so that a predetermined symbol arrangement is displayed on the display unit (72). ) Can be stopped, and the rotation position of the rotating reel (40) when the stop control by the automatic stop control means (160) starts is displayed on the display unit (72). If the rotation position is obtained, the rotating reel (40) being rotated is stopped so that a predetermined symbol arrangement is displayed on the display section (72). In other cases, for example, the lottery result of the winning lottery means (110) indicates that the predetermined symbol arrangement is not displayed on the display unit (72), or when the stop control by the automatic stop control means (160) starts. If the rotation position of the rotary reel (40) is not a rotation position at which the predetermined symbol arrangement can be displayed on the display section (72), the predetermined symbol arrangement is not displayed on the display section (72). In other words, the rotating reel (40) is stopped.

In addition, when stop control is performed using the automatic stop control means (160), stop control is performed by the player's stop operation, such as stop control based only on the lottery result of the winning lottery means (110). It is also possible to perform a different stop control. Further, the condition for performing the stop control by the automatic stop control means (160) is constant after the rotating reel (40) starts rotating without passing a certain time after the start operation by the player. After rotating the number of times, etc.
“Automatic stop position estimation means (170)” means that the stop position at which each rotary reel (40) will stop when the stop control by the automatic stop control means (160) is performed is a stop operation by the player. It is for estimating before is done. For example, in the case of a slot machine (10) in which the stop control by the automatic stop control means (160) is performed for a certain time after the start operation of the player, each rotation at the time when the start operation by the player is performed The rotation position of the reel (40) is detected by the rotation position detecting means (130), and the rotation of each rotation reel (40) that will stop after a predetermined time based on a predetermined rotation pattern of the rotation reel (40). Estimate the position.

  The “automatic stop presentation means (200)” is for performing presentation based on the estimation result of the automatic stop position estimation means (170). For example, when the stop control by the automatic stop control means (160) is performed based on the stop position of each rotary reel (40) estimated by the automatic stop position estimation means (170), the display section (72) displays Predict the type and arrangement of symbols that will be played. Then, all of the predicted symbol types and arrangements are displayed on a liquid crystal display (79) mounted on the gaming machine (10), an EL display device, or the like. Also, instead of displaying all the types and arrangements of symbols that will be displayed on the display section (72), for example, only a part of a predetermined symbol arrangement or profits that will be given to the player Only the size or a symbol representing a predetermined symbol arrangement may be displayed.

According to the present invention, the result of the stop control by the automatic stop control means is estimated, and an effect based on the estimation result is performed. If it does in this way, as a result of stop control by an automatic stop control means, it will become known before stop operation whether a predetermined symbol arrangement is displayed on a display part. That is, according to the present invention, even a player unfamiliar with a game can obtain an opportunity to stop each rotating reel so that a predetermined symbol arrangement is displayed on the display unit. Furthermore, in order to provide an opportunity for a player who is unfamiliar with the game to stop each rotating reel so that a predetermined symbol arrangement is displayed on the display unit, an extra symbol arrangement is attached to the rotating reel. There is no need to add restrictions.

In the best mode of the present invention, a slot machine 10 as a gaming machine will be described. In this slot machine, “winning” means that each rotary reel 40 can be stopped so that a predetermined symbol arrangement is displayed in the symbol display window 72 as a lottery result of the role lottery means 110. The “winning” means that each rotating reel 40 is stopped so that a predetermined symbol arrangement is displayed in the symbol display window 72 when all the rotating reels 40 are stopped.

There is a losing).

  In the present embodiment, when the lottery result of the winning lottery means 110 is BB winning, stop control of each rotary reel 40 is performed based on the BB winning. Then, three symbols “7 (red)” or “7 (blue)” can be arranged on any valid winning line 400, and “7 (red)” or “7 (blue)”. For symbols other than, three symbols will not be aligned on any valid winning line 400, and the “cherry” symbol attached to the left reel 41 will not stop on any valid winning line 400. . Then, when the rotation of all three rotary reels 40 is stopped, if three “7 (red)” or “7 (blue)” symbols are aligned on any valid winning line 400, the BB winning is achieved. Then, 15 medals are paid out, and then the BB game is entered.

  Further, in the present embodiment, when the lottery result of the winning lottery means 110 is RB winning, stop control of each rotary reel 40 is performed based on the RB winning. Then, three symbols of “BAR” can be arranged on any valid winning line 400, and three symbols other than “BAR” are not arranged on any valid winning line 400. In addition, the symbol “cherry” attached to the left reel 41 does not stop on any valid pay line 400. Then, when all three rotating reels 40 stop rotating, if three “BAR” symbols are aligned on any valid pay line 400, an RB win is awarded and 15 medals are paid out. After that, the RB game is entered.

  Further, in the present embodiment, when the lottery result of the combination lottery means 110 is the first small combination winning, stop control of each rotating reel 40 is performed based on the first small combination winning. Then, three symbols of “Bell” can be arranged on any valid winning line 400, and three symbols other than “Bell” are not arranged on any valid winning line 400. In addition, the symbol “cherry” attached to the left reel 41 does not stop on any valid pay line 400. Then, when all three rotating reels 40 stop rotating, if the three “bell” symbols are aligned on any valid winning line 400, the first small role winning is awarded and 12 medals are awarded. To be paid out.

  Further, in the present embodiment, when the lottery result of the part lottery means 110 becomes the second small part winning, the stop control of each rotating reel 40 is performed based on the second small part winning. As a result, three “watermelon” symbols can be arranged on any valid winning line 400, and three symbols other than “watermelon” cannot be arranged on any valid winning line 400. In addition, the symbol “cherry” attached to the left reel 41 does not stop on any valid pay line 400. Then, when the rotation of all three rotating reels 40 stops and the three “watermelon” symbols are aligned on any valid winning line 400, the second small role winning is awarded and eight medals are awarded. To be paid out.

  Further, in the present embodiment, when the lottery result of the part lottery means 110 is the third small part winning, stop control of each rotary reel 40 is performed based on the third small part winning. Then, the symbol “cherry” attached to the left reel 41 can stop on any valid winning line 400, and any symbol other than “cherry” can be selected for any valid winning line 400. There will be no three on top. When the rotation of all three rotating reels 40 stops and the “cherry” symbol attached to the left reel 41 stops on any valid pay line 400, the middle reel 42 and the right reel Regardless of the stop position of 43, it becomes the third small role prize and two medals are paid out. If the number of inserted medals is 3, and the position where the symbol “cherry” is displayed is the upper or lower level of the symbol display window 72, four medals are paid out.

The game can be played again under the same conditions as the previous game.

Further, in the present embodiment, when the lottery result of the combination lottery means 110 is lost, stop control of each rotary reel 40 is performed based on the loss. As a result, three symbols of the same type are not arranged on any valid winning line 400, and the symbol “cherry” attached to the left reel 41 stops on any valid winning line 400. Disappear. Then, when all three rotating reels 40 stop rotating, the “cherry” attached to the left reel 41 does not have three symbols of the same type on any valid winning line 400. If the symbol is not stopped on any valid winning line 400, there is no winning.
Further, in the present embodiment, when the lottery result of the winning lottery means 110 is BB winning, “BB internal hit information” is set in a predetermined area on the RAM. Also, once the BB internal winning information is set, it is held without being cleared until a BB winning is awarded. The BB internal winning information is cleared when a BB winning is awarded.

Further, in the present embodiment, when the lottery result of the winning lottery means 110 is RB winning, “RB internal hit information” is set in a predetermined area on the RAM. In addition, once the RB internal winning information is set, it is not cleared and held until an RB winning is awarded. The RB internal winning information is cleared when an RB winning is awarded.
Here, when the BB internal hit information is set, “inside the BB internal hit”, and when the RB internal hit information is set, “inside the RB internal hit”, the BB internal hit information is also set. The case where the information inside the RB is not set is set to “normal”.
During normal times, the lottery result of the role lottery means 110 is any one of BB winning, RB winning, first small winning combination, second small winning combination, third small winning combination, Replay winning, or lose.

In addition, during the inside of the BB, the lottery result of the role lottery means 110 is any one of BB winning, first small winning combination, second small winning combination, third small winning combination, or Replay winning.
In addition, during the inside of the BB, the winning probability of the BB winning becomes equal to the sum of the winning probability of the BB winning, the winning probability of the RB winning, and the probability of losing in the normal state. For this reason, the winning probability of winning the BB becomes extremely high while hitting the inside of the BB. The state where the winning probability of winning the BB is extremely high continues until the BB internal hit information is cleared. In other words, in the present embodiment, once the lottery result of the winning lottery means 110 is BB winning, the state where the winning probability of BB winning continues continues until the BB symbol array appears.

In addition, during the inside of the RB, the lottery result of the combination lottery means 110 is any one of RB winning, first small winning combination, second small winning combination, third small winning combination, or Replay winning.
In addition, during the inside of the RB, the winning probability of the RB winning is equal to the sum of the winning probability of the BB winning in the normal state, the winning probability of the RB winning, and the probability of losing. For this reason, the winning probability of RB winning becomes extremely high while hitting inside the RB. And the state where the winning probability of RB winning is extremely high continues until the RB internal hit information is cleared. In other words, in the present embodiment, once the lottery result of the winning lottery means 110 is RB winning, the state in which the winning probability of RB winning continues extremely high until the RB symbol array appears.

In the present embodiment, the state where the winning probability is high until the corresponding symbol arrangement appears is limited to the BB winning and the RB winning. That is, even if the first small role symbol arrangement cannot appear in the game in which the lottery result of the role lottery means 110 is the first small role winning, the winning probability of the first small role winning is increased in the subsequent game. Never be. The same applies to the second small role winning, the third small role winning, and the Replay winning.
(Specific game control means 102)
The RB game refers to a game having a higher profit grant probability than a general game. The specific game control means 102 is for controlling the RB game.

Hereinafter, the RB game in the present embodiment will be described.
When the lottery result of the winning lottery means 110 is RB winning, stop control of each rotating reel 40 is performed based on the RB winning and the rotation position of the corresponding rotating reel 40 when the stop switch 60 is operated. At this time, three symbols of “BAR” can be arranged on any valid winning line 400, and three symbols other than “BAR” are arranged on any valid winning line 400. Disappear. When all three rotating reels 40 stop rotating and three "BAR" symbols are placed on any valid winning line 400, an RB win is awarded and 15 medals are paid out. After that, the RB game is entered.

Further, during the RB game, a “JAC game” is performed. In the JAC game, the number of medals that can be inserted is one per game, and when three “R” symbols are arranged on the first winning line 401, a prize is awarded and 15 medals are paid out. Further, during the RB game, the JAC game can be played 12 times at the maximum, and 8 times can be won at the maximum. That is, if the JAC game is played 12 times or the winning is 8 times during the RB game, the RB game is ended. And it transfers to a general game.
(Specific introduction game control means 103)
A BB game refers to a game with a high probability of introducing a specific game. The specific introduction game control means 103 is for controlling the BB game.

Hereinafter, the BB game in the present embodiment will be described.
When the lottery result of the winning lottery means 110 is BB winning, stop control of each rotating reel 40 is performed based on the BB winning and the rotation position of the corresponding rotating reel 40 when the stop switch 60 is operated. At this time, three symbols “7 (red)” or “7 (blue)” can be arranged on any valid winning line 400, and “7 (red)” or “7 (blue)” As for symbols other than “,” three symbols are not arranged on any valid winning line 400. Then, when the rotation of all three rotary reels 40 is stopped, when three symbols “7 (red)” or “7 (blue)” are aligned on any valid winning line 400, BB A prize is won, 15 medals are paid out, and then the BB game is entered.

When the BB game is entered, first, a general game in the BB game is played.
Here, the general game in the BB game is referred to as “BB general game”.
In “general game during BB”, up to three medals can be inserted per game, as in general games other than during the BB game. In addition, when the rotation of all three rotary reels 40 is stopped, it is determined whether or not a winning has been achieved depending on whether or not a predetermined symbol arrangement has appeared.
However, in the “BB medium general game”, the winning probability of the RB winning, the first small role winning, the second small role winning, and the third small role winning is higher than that of the general game other than during the BB game. Thereby, the general game during BB is more advantageous for the player than the general game other than during the BB game. Further, in the “general game during BB”, when the lottery result of the winning lottery means 110 is RB winning, stop control of each rotating reel 40 is performed based on the RB winning. Then, in the “BB general game”, when three “R” symbols are arranged on any valid winning line 400, an RB win is made, and the “BB general game” is shifted to the RB game in the BB game. To do.

Here, the RB game in the BB game is referred to as an “BB RB game”.
In the “BB RB game”, the number of medals that can be inserted is one per game, and three “R” symbols are arranged on the first winning line 401, as in the normal RB game. A winning JAC game is held. Also, when winning a prize in the JAC game, 15 medals are paid out. Further, during the “BB RB game”, JAC games can be played 12 times at the maximum, and 8 times can be won at the maximum. That is, if the JAC game is played 12 times or the winning is 8 times during the “BB RB game”, the “BB RB game” is ended.

In addition, during the BB game, when the transition to the “BB RB game” is performed three times, or when a total of 30 games are played in the “BB general game”, the BB game ends. And it transfers to a general game.
Specifically, when a transition is made from a general game to a BB game, first, the first “BB in-game” is performed. In addition, when an RB winning is made in the first “BB medium game”, the process proceeds to the first “BB game in BB”. Then, when the first “BB RB game” is completed, the process proceeds to the second “BB general game”. In addition, when an RB winning is achieved in the second “general game in BB”, the process proceeds to the second “RB game in BB”. When the second “RB game during BB” is completed, the process proceeds to the third “BB general game”. Further, when an RB win is made in the third “BB in-game”, the game proceeds to the third “BB in-game”. Then, when the third “BB RB game” ends, the BB game also ends at the same time, and the game shifts to a general game.

Even if 30 games are played in the first “BB general game”, the BB game ends. And it transfers to a general game.
In addition, even if a total of 30 games are played in the first and second “BB in-game”, the BB game ends. And it transfers to a general game.
Also, even if a total of 30 games are played in the first, second and third “BB in-game games”, the BB game ends. And it transfers to a general game.
(Role lottery 110)
The role lottery means 110 is for performing a lottery to determine whether or not each rotary reel 40 can be stopped so that a predetermined symbol arrangement is displayed in the symbol display window 72.

The role lottery means 110 includes a random number generation means, a random number extraction means, a role lottery table, and a role lottery determination means, although not shown.
The random number generation means is for generating a random number for winning lottery within a predetermined range (for example, 0 to 16383 in decimal number).
The random number generating means can be constituted by, for example, an oscillation circuit and a counter circuit that counts clock signals generated by the oscillation circuit (so-called hard random number).
Further, the random number generating means can be constituted by means for generating random numbers by an average sampling method or means for generating random numbers by adding prime numbers, for example. Further, these means can be configured, for example, by causing a CPU to execute a predetermined program (so-called soft random number).

The random number extraction means is for extracting a random number generated by the random number generation means at a predetermined trigger (for example, operation of the start switch 50).
Since the random number generating means is constituted by a counter circuit or the like, the numerical value generated by the random number generating means is not strictly a random number. However, since the timing at which the start switch 50 is operated is considered to be random, the numerical value extracted by the random number extraction means can be substantially handled as a random number.
The winning lottery table stops each rotating reel 40 so that any random number within the range generated by the random number generation means is displayed on a valid winning line 400 in any of the winning symbol arrangement modes. Or whether each rotary reel 40 is stopped so that a winning symbol arrangement is not displayed on the valid winning line 400 is determined in advance.

In the role lottery table, for each random number within the range generated by the random number generating means, BB winning, RB winning, first small winning combination, second small winning combination, It is determined in advance whether to win three small roles, win Replay, or lose.
In the present embodiment, as the role lottery table, the “normal role lottery table” used during normal times, the “medium role lottery table per BB internal” used during BB internal hits, and the RB internal hits used. "RB internal winning lottery table", "BB game medium winning lottery table" used during BB general games, and "RB game medium winning lottery table" used during RB games and BB RB games And.

In addition, the regular role lottery table has a BB win, an RB win, a first small role win, a second small role win, a third small role win, a Replay win, and a lose as a lottery result. The ratio is determined.
In addition, the BB internal winning lottery table defines BB winning, first small role winning, second small role winning, third small role winning, and Replay winning as a lottery result at predetermined ratios, respectively. ing. In addition, the ratios of the first small role winning, the second small role winning, the third small role winning, and the Replay winning in the BB internal winning lottery table are the first small role winning and the second small role winning in the normal role lottery table. The percentages of winning, third small role winning, and Replay winning are equal. In addition, the BB winning ratio in the BB internal winning lottery table is equal to the sum of the BB winning ratio, the RB winning ratio, and the lost ratio in the normal winning lottery table. Thereby, the winning probability of winning the BB becomes extremely high while hitting the inside of the BB.

  In addition, the RB internal winning lottery table defines RB winning, first small role winning, second small role winning, third small role winning, and Replay winning as a lottery result at predetermined ratios, respectively. ing. In addition, the ratio of the first small role winning, the second small role winning, the third small role winning, and the Replay winning in the RB internal winning lottery table is the first small role winning and the second small role winning in the normal role lottery table. The percentages of winning, third small role winning, and Replay winning are equal. Further, the RB winning ratio in the RB internal winning lottery table is equal to the sum of the BB winning ratio, the RB winning ratio, and the loss ratio in the normal winning lottery table. Thereby, the winning probability of the RB winning becomes extremely high during the inside of the RB.

In addition, the BB game mid-lot lottery table defines RB win, first small win, second small win, third small win, and loss at predetermined ratios as lottery results. . In addition, the ratios of the RB winning, the first small role winning, the second small role winning, and the third small role winning in the BB game middle role lottery table are RB winning, first small role winning, second in the normal role lottery table. It is higher than the ratio of winning the small role and winning the third small role. Thereby, during the BB general game, the winning probability of the RB winning, the first small role winning, the second small role winning, and the third small role winning is higher than during the general game other than during the BB game.
In addition, the RB game mid-lot lottery table defines JAC wins and loses at predetermined ratios as the lottery results. During the RB game, the winning probability of winning the JAC is very high, and the probability of granting profit is higher than during the general game.

The role lottery determination means is for comparing the random number extracted by the random number extraction means with the role lottery table to determine the lottery result.
This combination lottery determination means compares the random number extracted by the random number extraction means with the combination lottery table, and if it is normal, it is BB winning, RB winning, first small winning combination, second small winning combination It is determined whether it is a win, a third small role win, a replay win, or a loss. In addition, if the inside of the BB is hit, it is determined whether it is a BB win, a first small winning combination, a second small winning combination, a third small winning combination, or a Replay winning. If the RB is hit, it is determined whether it is RB winning, first small winning combination, second small winning combination, third small winning combination, or Replay winning. In addition, if it is during a general game during BB, it is determined whether it is RB winning, first small combination winning, second small combination winning, third small combination winning, or lost. Further, if the RB game or the BB game is being played, it is determined whether the JAC is won or lost.

(Rotation control means 120)
The rotation control means 120 is for controlling the rotation of each rotary reel 40.
Based on the operation of the start switch 50, the rotation control means 120 starts the rotation of each rotary reel 40, performs an acceleration process for accelerating the rotation of each rotary reel 40, and the rotation speed reaches a predetermined speed. Sometimes, the acceleration process is terminated, and a constant speed process for rotating each rotary reel 40 at a constant speed is performed to keep the rotation speed constant.
In the present embodiment, a stepping motor 35 having a four-phase basic step angle of 1.43 degrees is employed as power for rotating the rotary reel 40. In order to operate the stepping motor 35, it is necessary to output a pulse. In the present embodiment, 1-2 phase excitation is employed as a pulse output method. The stepping motor 35 has a structure that requires the output of 504 pulses to rotate the rotary reel 40 once. In addition, since 21 symbols are evenly attached to the surface of the rotating reel 40, 24 pulses are required to rotate the rotating reel 40 by one symbol. Therefore, in order to rotate the rotary reel 40 from a certain proper stop position to the next proper stop position, it is necessary to output 24 pulses.

In the present embodiment, one pulse is output at regular intervals during constant speed processing. For this reason, the rotating reel 40 rotates at a constant speed. At that time, the time required for one rotation of the rotating reel (the time required for outputting 504 pulses) is 750 ms. That is, when the rotating reel 40 rotates at a constant speed, the interval at which one pulse is output is about 1.5 ms, and 672 pulses are output per second. That is, when the rotating reel 40 rotates at a constant speed, the rotating reel 40 rotates by 28 symbols per second.
On the other hand, during the acceleration process, the interval at which one pulse is output is not constant. During the acceleration process, the interval at which one pulse is output is gradually shortened to accelerate the rotation speed of the rotary reel 40. This acceleration process is always performed in a certain procedure, and is performed while outputting a total of 23 pulses in 125 ms. When the acceleration process is completed, the rotating reel 40 rotates at a speed of 750 ms, and the constant speed process is performed.

Hereinafter, rotation control of each rotary reel 40 in the present embodiment will be described.
When the player operates the start switch 50, the rotation control unit 120 first waits until 175 ms elapses. When 175 ms has elapsed, the rotation control means 120 detects whether 4.1 seconds have elapsed since the previous game ended.
When 175 ms has elapsed since the operation of the start switch 50 and 4.1 seconds have elapsed since the end of the previous game, the rotation control means 120 is configured to start each rotation reel 40 simultaneously. A pulse for starting the rotation of the rotary reel 40 is output.
On the other hand, when 175 ms has elapsed from the operation of the start switch 50 and 4.1 seconds have not elapsed since the previous game ended, the rotation control means 120 first starts the rotation of the right reel 43. The pulse is output. Subsequently, a pulse for starting the rotation of the middle reel 42 is output before 4.1 seconds have elapsed since the end of the previous game. Then, a pulse for starting the rotation of the left reel 41 is output when 4.1 seconds have elapsed since the end of the previous game. The output of the pulse for starting the rotation of the middle reel 42 is exactly between the output of the pulse for starting the rotation of the right reel 43 and the output of the pulse for starting the rotation of the left reel 41. To be done. Thereby, the rotation starts sequentially at equal time intervals in the order of the right reel 43 → the middle reel 42 → the left reel 41.

Then, acceleration processing is performed for each rotating reel 40 in order to gradually increase the rotation speed. When the speed of each rotary reel 40 reaches one rotation speed in 750 ms by the acceleration process, the acceleration process ends. Then, in order to continue rotating each reel 40 at a speed of one rotation at 750 ms, constant speed processing is performed with a constant interval (about 1.5 ms) at which one pulse is output.
(Rotation position detection means 130)
The rotational position detecting means 130 is for detecting the rotational position of each rotary reel 40.
In the present embodiment, the rotational position detecting means 130 identifies the rotational position of each rotating reel 40 based on the index signal and the number of pulses output for the operation of the stepping motor 35.

The index signal is a signal indicating that the index 48 provided on the spoke 46 of each rotary reel 40 has passed through the photo sensor 34 fixed to each reel stand 32. The photosensor 34 has a light emitting unit and a light receiving unit, and outputs an OFF signal when light emitted from the light emitting unit is detected by the light receiving unit. On the other hand, if the light emitted from the light emitting unit is not detected by the light receiving unit, an ON signal is output. In the present embodiment, when the index 48 passes through the photosensor 34, the light emitted from the light emitting unit is blocked and an ON signal is output. That is, this ON signal is an index signal.
In the present embodiment, the position of the rotating reel 40 when the index signal is output is set as the reference position.

The rotational position detecting means 130 in the present embodiment will be described using the left reel 41.
First, the start switch 50 is operated by the player, and the rotation of the left reel 41 starts. At this time, the left reel 41 is subjected to acceleration processing. When the acceleration process is completed and the left reel 41 makes one rotation in 750 ms, the left reel 41 is rotated at a constant speed, and the rotation control means 120 performs the constant speed process. When the index signal is output at this time, the rotational position detecting means 130 detects that the left reel 41 is at the reference position. Further, the rotational position detecting means 130 counts the number of pulses output after the index signal is detected. The rotational position detection means 130 detects the rotational position of the left reel 41 based on the counted number of pulses. For example, if the number of pulses counted after the index signal is output is 230 pulses, the rotational position detecting means 130 detects that the left reel 41 is at a position rotated by 230 pulses from the reference position. The rotational position detecting means 130 repeats the detection of the index signal and the count of the number of pulses every time the left reel 41 makes one rotation.

The same applies to the middle reel 42 and the right reel 43.
In other words, the rotation position detection means 130 detects the rotation position of the rotation reel 40 by detecting the index signal and counting the number of pulses output after the detection of the index signal if the rotation reel 40 is rotating. If the rotating reel 40 is stopped, the number of pulses output from the last detection of the index signal to the stop is counted, and the stop position of the rotating reel 40 is detected.
(Stop control means 140)
The stop control means 140 is for performing stop control of each rotary reel 40.

The stop control means 140 determines that each rotary reel 40 is appropriate based on the lottery result of the winning lottery means 110 and the rotational position of each rotary reel 40 when each stop switch 60 is operated and a stop signal is output. The number of sliding frames is determined so as to stop at the stop position, and a pulse necessary for rotating each rotating reel 40 to rotate the number of sliding frames is output, and then each rotating reel 40 is stopped.
In this specification, “the number of sliding frames” means the number of appropriate stop positions that pass between the time when the stop signal is output and the corresponding rotating reel 40 stops at any appropriate stop position. Say.
For example, when the corresponding rotating reel 40 stops at the first appropriate stop position after the stop signal is output, the appropriate stop position that has passed between the stop signal being output and the corresponding rotating reel 40 being stopped is displayed. Since the number is “0”, the number of sliding frames is “0”.

In addition, when the rotation of the corresponding rotary reel 40 is stopped at the next appropriate stop position after the stop signal is output and the rotation of the corresponding rotary reel 40 is stopped at the next appropriate stop position, Since the number of appropriate stop positions that have passed before the rotation stops is “1”, the number of sliding symbols is “1”.
In the present embodiment, the number of sliding symbols is determined in advance in the “stop table”.
The stop table is for determining the stop position of each rotary reel 40, and the number of sliding symbols of each rotary reel 40 is determined according to the rotation position of the corresponding rotary reel 40 when the stop signal is output. It is predetermined. In the present embodiment, a plurality of types of stop tables are provided. That is, the stop table includes a BB stop table, an RB stop table, a first small role stop table, a second small role stop table, a third small role stop table, a Replay stop table, a lose stop table, and the like. In the BB stop table, the number of sliding symbols is determined so that a BB symbol arrangement can appear and a winning symbol arrangement other than the BB symbol arrangement cannot appear. In the RB stop table, the number of sliding symbols is determined so that an RB symbol array can appear and a winning symbol array other than the RB symbol array cannot appear. The first small role stop table has the number of sliding symbols so that the first small role symbol arrangement can appear and no winning symbol arrangement other than the first small role symbol arrangement appears. ing. The second small role stop table has a number of sliding symbols so that a second small role symbol arrangement can appear and a winning symbol arrangement other than the second small role symbol arrangement cannot appear. It has been established. The third small role stop table has a number of sliding symbols so that a third small role symbol arrangement can appear and a winning symbol arrangement other than the third small role symbol arrangement cannot appear. It has been established. In the Replay stop table, the number of sliding symbols is determined so that a Replay symbol array can appear and a winning symbol array other than the Replay symbol array cannot appear. Also, in the lose stop table, the number of sliding symbols is determined so that no winning symbol arrangement can appear.

Further, in the present embodiment, each stop table defines the number of sliding symbols of each rotary reel 40 within the range of 0 to 4.
Hereinafter, stop control by the stop control means 140 in the present embodiment will be described.
First, when the player operates the start switch 50, the lottery means 110 performs the lottery, and the rotation control means 120 starts the rotation of each rotary reel 40. The stop control means 140 determines which stop table is used for the stop control based on the lottery result of the combination lottery means 110.
Further, the rotation control means 120 starts the rotation of all the rotary reels 40, and after completing the acceleration process, performs the constant speed process. At this time, after each of the rotating reels 40 has shifted to a constant speed and an index signal is output, and 700 ms has elapsed since all the rotating reels 40 have rotated, the player can operate the stop switch 60 effectively. Become. In other words, the acceleration processing for all the rotating reels 40 is completed, and the index signal is output after the acceleration processing is completed before 700 ms have passed since the rotation of all the rotating reels 40 is started. In this case, the operation of the stop switch 60 by the player becomes effective when 700 ms has elapsed since all the rotating reels 40 started to rotate.

  Then, when the stop switch 60 is operated by the player and a stop signal is output, the stop control means 140 is based on the selected stop table and the rotational position of the rotary reel 40 when the stop signal is output. Thus, after determining the number of sliding frames of each rotary reel 40 and outputting a necessary pulse, each rotary reel 40 is stopped. That is, when the stop switch 60 is operated and a stop signal is output, the stop control means 140 determines the number of sliding symbols from the appropriate stop position that reaches first after the stop signal is output, and the first appropriate stop After outputting a total pulse of a pulse necessary for rotating the rotary reel 40 to the position and a pulse necessary for rotating the rotary reel 40 by the number of sliding frames, the rotary reel 40 is stopped.

In the present embodiment, the stop signal is not output even if the stop switch 60 corresponding to another rotary reel 40 is operated for 209 ms after the stop signal is output to one rotary reel 40. .
For example, when three medals are inserted and the start switch 50 is operated, lottery by the lottery means 110 and rotation of the rotary reel 40 by the rotation control means 120 are started. At this time, when the lottery result of the winning lottery means 110 is a loss win, the stop control means 140 selects a stop table as shown in FIG. 8 from a plurality of stop tables. FIG. 8 shows an example of the stop table.

  When the stop table shown in FIG. 8 is used, the symbol “02” “watermelon” on the left reel 41 is at an appropriate stop position located in the middle stage of the symbol display window 72, and the left stop switch 60 is operated to the left. When the reel stop signal is output, the number of sliding frames of the left reel 41 is determined to be “0”. Then, no pulse is output, and the rotation of the left reel 41 is stopped at the first proper stop position after the operation of the left stop switch 60. As a result, the symbol “7 (red)” of the left reel 41 is displayed on the upper left side of the symbol display window 72, the symbol “watermelon” of the number 02 is displayed on the middle portion, In the same lower row, the symbol “03” of No. 03 stops.

  In addition, the middle stop switch 60 is operated to output a middle reel stop signal immediately before the “bell” number 02 of the middle reel 42 is located in the middle of the symbol display window 72 (for example, 10 pulses above). Then, the number of sliding frames of the middle reel 42 is determined as “0”. Then, a pulse for rotating the middle reel 42 to the first proper stop position after the operation of the central stop switch 60 is output (for example, 10 pulses for rotating the middle reel 42 to the first proper stop position). Is output), the rotation of the middle reel 42 is stopped. As a result, in the center upper part of the symbol display window 72, the 01 "7 (red)" symbol of the middle reel 42, the 02 "bell" symbol in the same middle stage, In the lower row, the 03 “Cherry” symbol will stop.

  Also, the stop switch 60 at the center is operated to output a right reel stop signal immediately before the symbol “Bell” of No. 03 on the right reel 43 is positioned in the middle of the symbol display window 72 (for example, 10 pulses above). Then, the number of sliding frames of the right reel 43 is determined as “2”. Then, the first proper stop position after the operation of the right stop switch 60 is passed, the next proper stop position is passed, and a pulse output for rotating the right reel 43 to the third proper stop position is output. Rotation of the right reel 43 is performed (for example, 58 pulses are output by adding 10 pulses for rotating the right reel 43 to the first proper stop position and 48 pulses for rotating the sliding frame number 2). Stops. As a result, in the upper right side of the symbol display window 72, the 00 “cherry” symbol of the right reel 43, the same “01 (red)” symbol in the middle reel, In the lower row, the symbol “Watermelon” of No. 02 stops.

Note that the stop control of the rotating reel 40 as described above is a control using a stop table, and is therefore called “table control” or the like.
(Winning determination means 150)
The winning determination means 150 detects the stop position of each rotating reel 40 by the rotation position detecting means 130 when the rotation of all the rotating reels 40 is stopped, so that a predetermined symbol arrangement is displayed on the symbol display window 72. It is for determining whether or not a predetermined symbol arrangement is displayed in the symbol display window 72 by determining whether or not each rotary reel 40 is stopped at a proper stop position.
In the present embodiment, for each rotating reel 40, which symbol is displayed in which position on the symbol display window 72 corresponding to the stop position of each rotating reel 40 is stored in advance in the ROM. As a result, by detecting the stop position of each rotary reel 40, it is possible to know which symbol is displayed at which stop position each rotary reel 40 displays.

In the present embodiment, the winning determination means 150 corresponds to the stop position of each rotating reel 40 detected by the rotating position detecting means 130 and the stop position stored in the ROM when all the rotating reels 40 are stopped. It is determined whether or not each rotary reel 40 is stopped at a stop position at which any winning symbol array is displayed on any valid winning line 400. And when it stops at the stop position where the symbol arrangement | sequence which becomes a prize appears, it determines with winning of a predetermined | prescribed role, and when it stops at the stop position where a predetermined symbol arrangement | sequence does not appear, it determines with loss.
The winning determination means 150 is configured such that when all the rotating reels 40 stop rotating, each rotating reel 40 is in a stop position where three “7 (red)” symbols are aligned on any valid winning line 400. If it is stopped, it is determined as “BB winning”. The same applies to the case where each rotary reel 40 is stopped at the stop position where three “7 (blue)” symbols are aligned on any valid winning line 400.

Further, the winning determination means 150 stops each rotating reel 40 at a stopping position where three “BAR” symbols are aligned on any valid winning line 400 when the rotation of all the rotating reels 40 is stopped. If it is, it is determined as “RB winning”.
Further, the winning determination means 150 stops each reel 40 at a stop position where three “bell” symbols are aligned on any valid winning line 300 when the rotation of all the reels 40 stops. If it is, it is determined as “first small role winning”.
In addition, the winning determination means 150 is configured to stop each rotary reel 40 at a stop position where three “watermelon” symbols are aligned on any valid winning line 400 when the rotation of all the rotary reels 40 is stopped. If it is, it is determined as “second small role winning”.

The winning determination means 150 is a stop position where the symbol “cherry” attached to the left reel 41 is positioned on any valid winning line 400 when the rotation of all the rotating reels 40 is stopped. When each of the rotating reels 40 is stopped, it is determined that the third small winning combination is won regardless of the stop positions of the middle reel 42 and the right reel 43.
In addition, the winning determination means 150 is configured to stop each rotating reel 40 at a stop position where three “R” symbols are aligned on any valid winning line 400 when the rotation of all the rotating reels 40 is stopped. If it is, it is determined as “Replay winning”.
Further, the winning determination means 150 is attached to the left reel 41 when all of the rotary reels 40 are stopped and the same type of three symbols are not arranged on any effective winning line 400. If each rotating reel 40 is stopped at a stop position at which the “Cherry” symbol does not appear on any valid winning line 400, it is determined as “lost”.

(Automatic stop control means 160)
The automatic stop control means 160 stops the rotation of each rotary reel 40 even if the player does not operate the stop switch 60 after a predetermined time has elapsed since the player's operation of the stop switch 60 becomes effective. Is for.
This automatic stop control means 160 allows the player to operate the stop switch 60 when the stop switch 60 is not operated even after 31 seconds have elapsed since the player's operation of the stop switch 60 became effective. Even if not, a stop signal is output. Then, based on the lottery result of the winning lottery means 110 and the rotational position of each rotating reel 40 when the stop signal is output, the number of sliding symbols of each rotating reel 40 is determined and the necessary pulses are output. Each rotary reel 40 is stopped. That is, when the stop signal is output, the automatic stop control means 160 determines the number of sliding symbols from the appropriate stop position that is reached first after the stop signal is output, and moves the rotary reel 40 to the first appropriate stop position. After outputting a pulse that is a sum of a pulse necessary for rotating and a pulse necessary for rotating the rotating reel 40 by the number of sliding frames, the rotating reel 40 is stopped.

Hereinafter, stop control by the automatic stop control means 160 in the present embodiment will be described.
First, when the player operates the start switch 50, the lottery means 110 performs lottery, and the rotation control means 120 starts rotating the rotary reel 40. Further, based on the lottery result of the combination lottery means 110, it is determined which stop table is used to perform the stop control by the automatic stop control means 160. The stop table used at this time is the same as the stop table used by the stop control means 140.
If the player does not operate the stop switch 60 even after 31 seconds have elapsed since the operation of the stop switch 60 is enabled, the rotating reel 40 located on the left of the rotating reels 40 that are rotating Is output at each 209 ms interval from the rotation reel 40.

Specifically, when all three rotating reels 40 are rotating, a left reel stop signal is output 31 seconds after the operation of the stop switch 60 becomes effective. Further, a middle reel stop signal is output 209 ms after the left reel stop signal is output. The automatic stop control means outputs a right reel stop signal 209 ms after outputting the middle reel stop signal.
In addition, when any one of the three rotary reels 40 is stopped by the player's operation of the stop switch 60, a stop signal is issued only to the two rotating reels 40 that are rotating. Is output. For example, when the stop switch corresponding to the left reel 41 is operated and the left reel 41 is stopped, the middle reel stop signal is output 31 seconds after the stop operation becomes effective. Then, a right reel stop signal is output 209 ms after the middle reel stop signal is output.

Further, when any two of the three rotating reels 40 are stopped by the player's operation of the stop switch 60, a stop signal is issued only to one rotating reel 40 that is rotating. Is output. For example, when the stop switch corresponding to the left reel 41 and the middle reel 42 is operated and the left reel 41 and the middle reel 42 are stopped, the right reel stop signal is issued 31 seconds after the stop operation becomes effective. Output.
In addition, when a stop signal is output for each rotary reel 40, the automatic stop control means 160 determines the number of sliding symbols based on the selected stop table and the rotation position when the stop signal is output. After outputting the necessary pulse, stop the rotation. In other words, when the stop signal is output, the number of sliding symbols from the proper stop position that is reached first after the stop signal is output is determined, and the pulses necessary for rotating the rotary reel 40 to the first proper stop position. And a pulse obtained by adding the pulses necessary to rotate the rotating reel 40 for the number of sliding frames, and then the rotating reel 40 is stopped.

(Automatic stop position estimation means 170)
The automatic stop position estimating means 170 performs stop control by the automatic stop control means 160 based on the rotational position of each rotary reel 40 and the number of pulses output until the stop control is performed by the automatic stop control means 160. In this case, the stop position where each rotary reel 40 will stop is estimated in advance.
In the present embodiment, the automatic stop position estimating means 170, when the operation of the stop switch 60 is enabled, based on the rotation position of each rotary reel 40 when the operation of the stop switch 60 is enabled, Estimate.

Further, as shown in FIG. 2, the automatic stop position estimating means 170 in this embodiment includes an operation effective position detecting means 180, an elapsed time before starting automatic stop calculating means 181, and an output pulse calculating means 182 before starting automatic stop. An automatic stop start position calculating means 183, an automatic stop output pulse calculating means 184, and an automatic stop position calculating means 185.
The operation effective position detection means 180 is for detecting the operation effective position. The operation effective position is the rotation position of each rotary reel 40 when the operation of the stop switch 60 is enabled. The operation effective position detection unit 180 detects the operation effective position of each rotary reel 40 based on the detection result of the rotation position detection unit 130 when the operation of the stop switch 60 is enabled.

The automatic stop start elapsed time calculation means 181 is for calculating the elapsed time before the start of automatic stop. The elapsed time before the start of automatic stop is the time that will elapse from when the operation of the stop switch 60 becomes effective until the stop signal is output to each rotary reel 40 by the automatic stop control means 160. That is.
In the present embodiment, the time from when the operation of the stop switch 60 becomes valid until the stop signal is output to the left reel 41 by the automatic stop control means 160 is 31 seconds. The stop signal is output to the middle reel 42 after 209 ms from the output of the stop signal to the left reel 41, and the stop signal is output to the right reel 43. 209 ms after the stop signal is output to the middle reel 42.

In the present embodiment, if any one of the stop switches 60 is operated before the first stop signal is output by the automatic stop control means 160, the rotation of the rotary reel 40 corresponding to the operated stop switch 60 is performed. Stops. Then, 31 seconds after the operation of the stop switch 60 becomes effective, a stop signal is output to the rotating reel 40 located on the left side among the rotating reels 40 being rotated, and 209 ms later, the position is located on the right side. A stop signal is output to the rotating reel 40 during rotation.
Then, if one of the stop switches 60 corresponding to the rotating reel 40 is further operated to stop the rotating reel 40 being rotated, the remaining 31 seconds after the operation of the stop switch 60 becomes effective A stop signal is output to the rotating reel 40 during rotation to stop the rotation.

Therefore, in the present embodiment, for example, when both the left reel 41 and the middle reel 42 are rotating, and the middle reel 42 is rotating, the left reel 41 is operated by the player's stop switch 60. Thus, the time until the stop signal is output to the middle reel 42 differs depending on whether the rotation is stopped.
As described above, in the present embodiment, by grasping which rotary reel 40 is rotating, after the operation of the stop switch 60 becomes effective, the automatic stop control means 160 is applied to each rotary reel 40. Thus, the time until the stop signal is output can be calculated. That is, the automatic stop start elapsed time calculation means 181 can calculate the elapsed time before the automatic stop start of each rotary reel 40 by grasping which rotary reel 40 is rotating. Further, the automatic stop start elapsed time calculation means 181 can recalculate the automatic stop start elapsed time when the stop switch 60 is operated.

The output pulse calculating means 182 before starting automatic stop is based on the interval at which one pulse is output and the elapsed time before starting automatic stop calculated by the elapsed time before starting automatic stop 181. This is for calculating the number of previous output pulses. The number of output pulses before the start of automatic stop will be output to each rotating reel 40 from when the operation of the stop switch 60 becomes effective until the stop signal is output by the automatic stop control means 160. It is the number of pulses.
The automatic stop start position calculating means 183 is for calculating the automatic stop start position based on the operation effective position and the number of output pulses before the automatic stop start. The automatic stop start position is the rotational position of each rotary reel 40 when a stop signal is output by the automatic stop control means 160. The automatic stop start position calculation means 183 calculates the rotation position that would be located when the number of output pulses before the automatic stop start is output from the operation effective position as the automatic stop start position.

  The automatic stop output pulse calculation means 184 is an automatic stop output pulse based on the automatic stop start position calculated by the automatic stop start position calculation means 183 and the stop table selected by the hand lottery means 110. This is for calculating the number. In the present embodiment, the automatic stop control means 160 performs stop control based on the automatic stop start position and the selected stop table. At that time, the automatic stop control means 160 outputs a pulse for rotating from the automatic stop start position to the next appropriate stop position for each rotating reel 40, and is determined in the stop table for the appropriate stop position. Pulses for rotating each rotary reel 40 are output by the number of sliding frames. At this time, the number of pulses output to rotate each reel 40 from the automatic stop start position to the first appropriate stop position and further rotate the number of sliding frames is referred to as the number of output pulses during automatic stop.

Then, the automatic stop position calculating means 185 means that the number of output pulses during automatic stop calculated by the automatic stop output pulse calculating means 184 is output from the rotational position calculated by the automatic stop start position calculating means 183. This is for calculating the final planned stop position of each rotary reel 40 that will stop.
Further, when any stop switch 60 is operated by the player, the automatic stop start elapsed time calculation means 181, the automatic stop start output pulse calculation means 182 and the automatic stop start position calculation means 183. Then, the automatic stop position estimation means 170 recalculates the automatic stop position output means 184 and the automatic stop position calculation means 185, thereby reestimating the estimation by the automatic stop position estimation means 170.

The automatic stop position estimating means 170 in the present embodiment will be described below.
For example, when three medals are inserted and the start switch 50 is operated, lottery by the lottery means 110 and rotation of the rotary reel 40 by the rotation control means 120 are started. At this time, if the lottery result of the winning lottery means 110 is lost, the stop control means 140 selects a stop table as shown in FIG. 8 from a plurality of stop tables. FIG. 8 shows an example of the stop table.
Then, after all the rotating reels 40 start rotating and shift to constant speed rotation, when the operation of the stop switch 60 becomes valid, the automatic stop position estimating means 170 performs estimation.

Specifically, when the operation of the stop switch 60 becomes valid, the operation effective position is detected by the operation effective position detection means 180. At this time, the rotation position of each rotary reel 40 is the proper stop position where the left reel 41 is the reference position, the middle reel 42 is the “bell” symbol of frame number 02, the middle position of the symbol display window 72, the right reel 43 It is assumed that the symbol “7 (red)” of frame number 01 is positioned 10 pulses above the proper stop maintenance located in the middle stage of the symbol display window 72.
Further, the elapsed time before starting automatic stop calculating means 181 calculates the time that will elapse from when the operation of the stop switch 60 becomes effective until the stop control by the automatic stop control means 160 is performed. At this time, any stop switch 60 is not operated. For this reason, the elapsed time before the start of automatic stop is 31 seconds for the left reel 41, 31.209 seconds for the middle reel 42, and 31.418 seconds for the right reel 43.

Then, the output pulse calculating means 182 before starting automatic stop starts before the automatic stop start that will be output to each rotating reel 40 based on the interval at which one pulse is output and the elapsed time before starting automatic stop. Calculate the number of output pulses. At this time, the number of output pulses before the start of automatic stop is 20832 pulses for 31 seconds for the left reel 41, 20972 pulses for 31.209 seconds for the middle reel 42, and 21112 pulses for 31.418 seconds for the right reel 43.
Here, the automatic stop start position calculating means 183 calculates the rotational position of each rotary reel 40 when the automatic stop control means 160 outputs a stop signal. For the left reel 41, it is predicted that the left reel 41 has been rotated by 20832 pulses, that is, 41 rotations and 168 pulses from the effective operation position. Therefore, the “R” symbol of frame number 14 is located in the middle of the symbol display window 72. It is predicted that the stop position is appropriate. The middle reel 42 is predicted to rotate 20972 pulses, that is, 41 rotations and 308 pulses. Therefore, the “bell” symbol of frame number 10 is properly stopped at the middle of the symbol display window 72. From the position, it is predicted to be located 4 pulses above. The right reel 43 is predicted to rotate by 21112 pulses, that is, 41 rotations and 448 pulses. Therefore, the “watermelon” symbol of frame number 02 is properly stopped at the middle of the symbol display window 72. It is predicted that the position is 22 pulses above the position.

  Further, the output pulse calculation means 184 during automatic stop uses the number of sliding frames and the number of sliding frames when stop control is performed using the stop table of FIG. 8 based on the automatic stop start position of each rotary reel 40. The number of pulses required to rotate the is calculated. Then, for the left reel 41, the stop signal is output at the appropriate stop position where the “R” symbol of frame number 14 is located in the middle stage of the symbol display window 72, so the number of sliding symbols is determined to be “0”. Is done. Then, no pulse is output, and the number of output pulses during automatic stop is calculated as zero. For the middle reel 42, the “bell” symbol of frame number 10 is output at a position 4 pulses above the middle stage of the symbol display window 72, so the number of sliding symbols is “1”. It is determined. Then, it is calculated that 28 pulses for passing the first proper stop position after the stop signal is output and for rotating the middle reel 42 to the next proper stop position are output. For the right reel 43, a stop signal is output at the position of the “watermelon” symbol of frame number 02 at a position 22 pulses above the middle stage of the symbol display window 72, so the number of sliding symbols is “1”. It is determined. Then, it is calculated that 46 pulses for passing the first proper stop position after the stop signal is output and rotating the right reel 43 to the next proper stop position are output.

Then, the automatic stop position calculation means 185 stops if the rotation position calculated by the automatic stop start position calculation means 183 and the number of output pulses during automatic stop calculated by the automatic stop output pulse calculation means 184 are output. The final planned stop position of each rotating reel that will be calculated is calculated.
For the left reel 41, it is calculated that the “R” symbol of frame number 14 stops at an appropriate stop position located in the middle stage of the symbol display window 72. Then, when the stop control is performed by the automatic stop control means 160, the stop position of the left reel 41 is the appropriate stop position where the “R” symbol of frame number 14 is located in the middle stage of the symbol display window 72, and In the upper left side of the symbol display window 72, the 13th “watermelon” symbol of the left reel 41, the 14th “R” symbol in the middle, and the 15th “bell” in the lower row. It is estimated that the symbols are at the stop positions such that the symbols are respectively displayed.

Further, for the middle reel 42, the “bell” symbol of frame number 10 is calculated to stop when the middle reel 42 stops at a position where 28 pulses are output from the position above the middle four pulses of the symbol display window 72. . Then, when the stop control is performed by the automatic stop control means 160, the stop position of the middle reel 42 is the appropriate stop position where the “R” symbol of frame number 09 is located in the middle stage of the symbol display window 72, and In the upper center of the symbol display window 72, the "7 (blue)" symbol of No. 08 of the middle reel 42, the symbol "R" of No. 09 in the middle row, and the tenth symbol in the lower row. It is estimated that the “bell” symbol is at the stop position as displayed.
For the right reel 43, the “watermelon” symbol of frame number 02 is calculated when the right reel 43 stops at a position where 64 pulses are output from a position 22 pulses above the middle stage of the symbol display window 72. . Thus, when the stop control is performed by the automatic stop control means, the stop position of the right reel 43 is the appropriate stop position where the “7 (red)” symbol of frame number 01 is located in the middle stage of the symbol display window 72. In the upper right side of the symbol display window 72, the 00 “cherry” symbol of the right reel 43, the same “01 (red)” symbol in the middle, and the same symbol in the lower row. It is estimated that the number “02” “watermelon” is displayed at the stop position.

Further, even when any stop switch 60 is operated by the player, the elapsed time before automatic stop start calculating means 181, the output pulse calculating means 182 before starting automatic stop, the automatic stop start position calculating means 183, Then, the final stop position is estimated again by reestimating the output pulse calculation means 184 during automatic stop and the automatic stop position calculation means 185.
(Winning estimation means 190)
The winning estimation means 190 estimates the stop position of each rotary reel 40 by the automatic stop position estimation means 170, and if the stop control is performed by the automatic stop control means 160, a predetermined symbol arrangement is displayed on the symbol display window 72. In order to estimate whether or not a predetermined symbol arrangement will be displayed in the symbol display window 72 by determining whether or not each rotary reel 40 will stop at such a stop position. Is.

In the present embodiment, for each rotating reel 40, which symbol is displayed on the symbol display window 72 corresponding to the stop position of each rotating reel 40 is stored in advance in the ROM. Thus, by estimating the stop position of each rotary reel 40, it is possible to know which symbols each rotary reel 40 will display as a stop position.
In this embodiment, the winning estimation means 190 collates the stop position of each rotary reel 40 estimated by the automatic stop position estimation means 170 with the symbol corresponding to the stop position stored in the ROM, and performs automatic stop control. When all the rotating reels 40 are stopped by the means 160, each rotating reel 40 is stopped at a stop position such that any winning symbol arrangement is displayed on any valid winning line 400. Determine whether it will be. And if it will stop at the stop position where the winning symbol arrangement appears, it will guess that the predetermined combination will win, and if it will stop at the stopping position where the predetermined symbol arrangement does not appear, it will be lost Infer.

This winning inference means 190 determines that the result of stop control by the automatic stop control means 160 will stop at a stop position where three symbols of “7 (red)” are aligned on any valid winning line 400. Then, it is assumed that “BB winning”. The same applies to the case where it is determined that the symbol “7 (blue)” will stop at a stop position where three symbols are arranged on any valid pay line 400.
Further, it is determined that the winning estimation means 190 will stop at a stop position where three symbols “BAR” are aligned on any valid winning line 400 as a result of the stop control by the automatic stop control means 160. Then, it is estimated that “RB winning”.

Further, it is determined that the winning estimation means 190 will stop at the stop position where three “bell” symbols are aligned on any valid winning line 400 as a result of the stop control by the automatic stop control means 160. Then, it is estimated that “the first small role winning”.
Further, it is determined that the winning estimation means 190 will stop at a stop position where three “watermelon” symbols are aligned on any valid winning line 400 as a result of the stop control by the automatic stop control means 160. Then, it is estimated that “the second small role winning”.
Also, the winning estimation means 190 is a stop position where the symbol “cherry” attached to the left reel 41 is positioned on any valid winning line 400 as a result of the stop control by the automatic stop control means 160. If it is determined that it will stop, it is estimated that the third small winning combination is won regardless of the stop positions of the middle reel 42 and the right reel 43.

Further, it is determined that the winning estimation means 190 will stop at a stop position where three “R” symbols are aligned on any valid winning line 400 as a result of the stop control by the automatic stop control means 160. Then, it is estimated as “Replay Winner”.
Further, as a result of the stop control by the automatic stop control means 160, this winning inference means 190 does not have three symbols of the same type on any valid winning line 400 and is attached to the left reel 41. If it is determined that the symbol “cherry” is to be stopped at a stop position where it is not displayed on any valid winning line 400, it is assumed that the symbol is “lost”.
The winning estimation means 190 can make a prediction by using the winning determination means 150 based on the estimation result of the automatic stop position estimating means 170.

(Automatic stop effect means 200)
The automatic stop presentation means 200 is for performing an effect on the liquid crystal display 79 based on the estimation result by the automatic stop position estimation means 170.
In the present embodiment, the BB symbol array serving as a BB prize is a symbol array corresponding to the largest profit. Then, when the estimation result by the automatic stop position estimation unit 170 is obtained and the winning estimation unit 190 estimates that “BB winning” is obtained, the automatic stop production unit 200 receives the BB winning as a result of the stop control by the automatic stop control unit 160. An effect that each rotary reel 40 stops at the stop position is displayed on the liquid crystal display 79. As an effect that each rotary reel 40 stops at the stop position where a BB winning is achieved, the effect is performed by displaying an image having three “7 (red)” or “7 (blue)”.

(Operation of slot machine 10)
The outline of the operation of the slot machine 10 according to the present embodiment (automatic stop effect process) will be described below based on the flowchart shown in FIG.
The automatic stop effect process is performed according to the following procedure.
In step A100, when the start switch 50 is operated by the player, the process proceeds to step A110.
In step A110, the lottery means 110 performs a lottery. Then, the process proceeds to Step A120.

In step A120, a determination is made as to whether or not the BB winning is made as the lottery result of the combination lottery means 110. Here, if it is determined that the lottery result of the combination lottery means 110 is BB winning, the process proceeds to step A130. On the other hand, when it is determined that the lottery result of the winning lottery means 110 is not BB winning, normal processing such as production based on the winning combination, reel rotation start processing, stop control by the automatic stop control means 160, etc. The process proceeds to the normal process in which is performed.
In step A130, reel rotation start processing is performed. The reel rotation start process is a process of starting rotation of each rotary reel 40 by the rotation control means 120. Then, the process proceeds to Step A140.

In step A140, it is determined whether or not the operation of the stop switch 60 has been validated. If it is determined that the operation of the stop switch 60 is valid, the process proceeds to step A150. On the other hand, if it is determined that the operation of the stop switch 60 is not enabled, it is determined again whether or not the operation of the stop switch 60 is possible.
In step A150, automatic stop position estimation is performed. The automatic stop position estimation means that the automatic stop position estimation means 170 estimates the stop position of each rotary reel 40 when the stop control by the automatic stop control means 160 is performed. Then, the process proceeds to Step A160.
In step A160, a winning prediction is performed. Winning estimation is to determine whether or not the stop position of each rotary reel 40 estimated by the automatic stop position estimating means 170 is a stop position at which a predetermined symbol arrangement is displayed, by the winning estimation means 190. It is. In the winning guess, it is presumed that a BB winning or other winnings will be made, or none of them will be won. Then, the process proceeds to Step A170.

In step A170, a determination is made as to whether or not a BB prize is expected based on the guess result of the winning guess. Here, if it is determined that a BB winning is made, the process proceeds to step A180. On the other hand, if it is determined that any other winning or no winning is made, the process proceeds to step A190.
In step A180, an automatic stop effect is performed. The automatic stop effect is to perform an effect on the liquid crystal display 79 before the player's stop operation based on the estimation result of the automatic stop position estimating means 170. Then, the process proceeds to Step A200.
In step A190, normal performance processing is performed. The normal effect process is to determine whether or not to perform a normal effect, what kind of effect to perform when performing a normal effect, and the like, and to perform an effect based on the determination. The normal effect is an effect performed based on the lottery result of the role lottery means 110 and the selected stop table. Then, the process proceeds to Step A200.

In step A200, it is determined whether or not the stop switch 60 has been operated by the player. Here, if it is determined that the player has operated the stop switch 60, the rotary reel 40 corresponding to the operated stop switch 60 is stopped, and the process proceeds to step A210. On the other hand, if it is determined that the player has not operated the stop switch 60, the process proceeds to step A220.
In step A210, it is determined whether there is a rotating reel 40 that is rotating. If it is determined that there is a rotating reel 40 that is rotating, the process returns to step A150, and the automatic stop position estimation is performed again. On the other hand, if it is determined that all the rotating reels 40 are already stopped and there are no rotating reels 40 being rotated, the process proceeds to step A240.

In step A220, it is determined whether 31 seconds have elapsed since the operation of the stop switch 60 was enabled. If it is determined that 31 seconds have elapsed, the process proceeds to step A230. On the other hand, if it is determined that 31 seconds have not elapsed, the process proceeds to step A200, where it is determined whether or not the stop switch 60 has been operated.
In step A230, automatic stop control is performed. The automatic stop control is to perform stop control by the automatic stop control means 160. Then, the process proceeds to Step A240.
In step A240, game processing is performed. The game process is to perform determination by the winning determination unit 150 or to pay out coins based on the determination. Then, the automatic stop effect ends.

  Thus, in the present embodiment, the result of the stop control by the automatic stop control means 160 is estimated. Further, when it is presumed that the result of the stop control by the automatic stop control means 160 will be a BB prize, an effect is given on the liquid crystal display 79 based on the estimation result before the player's stop operation. Then, even a player who is unfamiliar with the game can stop each rotating reel 40 so as to display the symbol arrangement for the BB prize. In addition, even players who are unfamiliar with the game have extra restrictions on the types and arrangement of symbols attached to the rotating reels 40 in order to stop the rotating reels 40 so as to display the symbol arrangement for winning the BB. There is no need to add.

Further, in the present embodiment, as a result of the stop control by the automatic stop control means 160, an effect based on the estimation result is performed only when the greatest profit is given to the player. By doing so, the expectation for the production increases.
Further, in the present embodiment, when the operation of the stop switch 60 becomes effective after the rotary reel 40 shifts to the constant speed rotation, the automatic stop position estimating means 170 performs estimation. By doing so, estimation of the result of the stop control by the automatic stop control means 160 becomes easy.
In the present embodiment, the estimation by the automatic stop position estimating means 170 is performed only when the lottery result by the winning lottery means 110 is BB winning so that the estimation by the automatic stop position estimating means 170 may be performed less frequently. To do.

(Second Embodiment)
(Explanation of drawings)
10 and 11 show a second embodiment.
10 is a block diagram of the automatic stop position estimating means 170, and FIG. 11 is a flowchart showing the operation of the slot machine 10.
In the first embodiment, the estimation by the automatic stop position estimating means 170 is performed when the operation of the stop switch 60 becomes valid, but in the second embodiment, the automatic stop position estimating means 170 is performed. The estimation is performed before the rotation of each rotary reel 40 is started.

The slot machine 10 according to the present embodiment is the same as the first embodiment except for the configuration other than the automatic stop position estimating means 170. Therefore, in this embodiment, the automatic stop position estimation unit 170 will be mainly described, and the description of components other than the automatic stop position estimation unit 170 will be omitted.
(Automatic stop position estimation means 170)
Similar to the automatic stop position estimating means 170 in the first embodiment, the automatic stop position estimating means 170 in the present embodiment is controlled to stop by the rotational position of each rotary reel 40 and the automatic stop control means 160. Based on the number of pulses output so far, when the stop control is performed by the automatic stop control means 160, the stop position where each rotary reel 40 will stop is estimated in advance.

In the present embodiment, the automatic stop position estimating means 170 performs estimation based on the stop position of each rotary reel 40 in the previous game when the player operates the start switch 50.
In this embodiment, as shown in FIG. 10, the automatic stop position estimating means 170 includes a previous stop position storage means 171, an elapsed time before rotation start calculating means 172, an acceleration end position calculating means 173, a reference Pre-position detection output pulse calculation means 174, reference position detection elapsed time calculation means 175, operation effective timing calculation means 176, operation effective pre-elapsed time calculation means 177, pre-operation effective output pulse calculation means 178, operation Effective position calculation means 179, elapsed time before start of automatic stop calculation means 181, output pulse calculation means 182 before automatic stop start, automatic stop start position calculation means 183, output pulse calculation means during automatic stop 184, automatic stop Position calculating means 185.

The previous stop position storage means 171 is for storing the stop position of each rotary reel 40 in the previous game. The previous stop position storage means 171 stores the stop position of each rotary reel 40 detected by the rotational position detection means 130 when the rotation of all the rotary reels 40 is stopped in the previous game.
The pre-rotation start elapsed time calculating means 172 is for calculating the pre-rotation start elapsed time. The elapsed time before the start of rotation is the time from the start of rotation of the first rotary reel 40 to the start of rotation of each rotary reel 40. Since the time when the rotating reel 40 that starts rotating first starts rotating is used as a reference for time measurement, the elapsed time before starting rotation of the rotating reel 40 that starts rotating first is always zero. In the present embodiment, rotation is controlled by the rotation control means 120 similar to that in the first embodiment. That is, when 175 ms has elapsed since the player operated the start switch 50, if 4.1 seconds have elapsed since the end of the previous game, all the spinning reels 40 start rotating simultaneously. The elapsed time before the start of rotation of all the rotary reels 40 is zero. In addition, when 175 ms has elapsed since the player operated the start switch 50, if 4.1 seconds have not elapsed since the end of the previous game, the right reel 43 → the middle reel 42 → the left reel The rotation is started so that the rotation starts at equal intervals in the order of 41, and so that the left reel 41 starts rotating when 4.1 seconds have elapsed since the end of the previous game. At this time, the elapsed time before starting the rotation of the right reel 43 is 0, and the elapsed time before starting the rotation of the middle reel 42 has elapsed from 4.1 seconds until the start switch 50 is operated after the end of the previous game. And half of the time minus 175 ms. Further, the elapsed time before starting the rotation of the left reel 41 is a time obtained by subtracting 175 ms from 4.1 seconds from the end of the previous game until the start switch 50 is operated.

The acceleration end position calculating means 173 is for calculating the acceleration end position of each rotary reel 40 based on the stop position in the previous game. The acceleration end position is a rotation position at the end of the acceleration process in each rotary reel 40. In the present embodiment, the acceleration process of each rotary reel 40 is terminated by outputting 23 pulses in 125 ms, and therefore, the acceleration end position of each rotary reel 40 is output from the stop position in the previous game. This is the rotational position.
Further, the output pulse calculation means 174 before reference position detection is for calculating the number of output pulses before reference position detection in each rotary reel 40. The number of output pulses before detecting the reference position is the number of pulses output from the end of acceleration processing to the first output of the index signal after the end of acceleration processing in each reel 40. The pre-reference position detection output pulse calculation means 174 calculates the number of output pulses before the reference position detection by calculating the number of pulses necessary for each rotating reel 40 to become the next reference position from the acceleration end position. .

  The reference position elapsed time calculating means 175 is for calculating the reference position detected elapsed time in each rotary reel 40. The elapsed time before reference position detection is the time that elapses between the end of the acceleration process and the first output of the index signal after the end of the acceleration process in each rotary reel 40. In the present embodiment, as in the first embodiment, the interval at which one pulse is output is constant. Therefore, the elapsed time before reference position detection calculating means 175 outputs the number of output pulses before reference position detection for each rotating reel 40 based on the number of output pulses before reference position detection and the interval at which one pulse is output. The time required to perform the calculation, that is, the time that elapses from when the acceleration process is completed until the first index signal is output is calculated.

  The operation effective timing calculation means 176 is for calculating the operation effective timing. The operation effective timing is a timing at which the operation of the stop switch 60 becomes effective. In the present embodiment, as in the first embodiment, an index signal is output after the acceleration processing has been completed for all the rotating reels 40, and 700 ms after all the rotating reels 40 have started rotating. When elapses, the operation of the stop switch 60 becomes effective. Therefore, there is a condition that an acceleration signal is finished in each rotary reel 40 and an index signal is output after the acceleration process is finished, and a condition that 700 ms elapses after all the rotary reels 40 start to rotate. When all are satisfied, the operation of the stop switch 60 becomes effective. The operation effective timing calculation means 176 indicates that the timing at which the index signal is output after the acceleration process is completed and the acceleration process is completed for each rotating reel 40, and 700 ms have elapsed since all the rotating reels 40 started rotating. The timing at which these conditions are satisfied and the operation of the stop switch 60 becomes valid can be calculated by comparing with the timing to perform. That is, the operation effective timing calculation means 176 first rotates each rotary reel 40 based on the elapsed time before starting rotation, 125 ms during acceleration processing, and the elapsed time before elapsed reference position. The time from when the rotating reel 40 starting the rotation starts rotating until the index signal is output after the acceleration process is completed is calculated. Further, the operation effective timing calculation unit 176, based on the calculation result of the elapsed time before rotation start calculation unit 172, starts rotating all the rotary reels 40 from the time when the rotary reel 40 that starts rotating first starts rotating. Calculate the time from the start until 700 ms elapses. The operation effective timing calculation means 176 compares these times, and the operation of the stop switch 60 becomes effective for the time when all the conditions are satisfied, that is, the latest time satisfying the conditions among these times. Calculate as timing.

Further, the pre-operation effective elapsed time calculating means 177 is for calculating the pre-operation effective elapsed time for each rotary reel 40. The elapsed time before the operation is effective is the time that elapses from when the acceleration process of the rotary reel 40 is completed until the operation of the stop switch 60 becomes effective. The pre-operation effective elapsed time calculating means 177 is based on the operation effective timing and the time from when the first rotating reel 40 starts rotating until the acceleration processing for each rotating reel 40 ends. Calculate the elapsed time before validity.
The pre-operation effective output pulse calculation means 178 is for calculating the number of output pulses before the operation effective in each rotary reel 40. The number of output pulses before the operation is the number of pulses output from the end of the acceleration process of each rotary reel 40 until the operation of the stop switch 60 becomes effective. The pre-operation effective output pulse calculation means 178 calculates the number of pulses that are output during the elapse of the pre-operation effective time based on the elapsed time before the operation effective and the interval at which one pulse is output.

The operation effective position calculation means 179 is for calculating the operation effective position. The operation effective position calculation means 179 calculates the operation effective position based on the acceleration end position and the number of output pulses before operation effective. That is, the rotation position that is located when the number of pulses before the operation is effective is output from the acceleration end position as the operation effective position of each rotary reel 40.
Also in the present embodiment, automatic stop start elapsed time calculation means 181, automatic stop start output pulse calculation means 182, automatic stop start position calculation means 183, automatic stop output pulse calculation means 184, automatic stop position calculation Since the means 185 has the same configuration as that of the first embodiment, the description thereof is omitted.

(Operation of slot machine 10)
The outline of the operation of the slot machine 10 according to the present embodiment (automatic stop effect process) will be described below based on the flowchart shown in FIG.
The automatic stop effect process is performed according to the following procedure.
In step B100, when the start switch 50 is operated by the player, the process proceeds to step B110.
In step B110, the lottery means 110 performs a lottery. Then, the process proceeds to Step B120.

In step B120, it is determined whether or not the BB winning is made as the lottery result of the combination lottery means 110. Here, if it is determined that the lottery result of the combination lottery means 110 is BB winning, the process proceeds to step B130. On the other hand, when it is determined that the lottery result of the winning lottery means 110 is not BB winning, normal processing such as production based on the winning combination, reel rotation start processing, stop control by the automatic stop control means 160, etc. The process proceeds to the normal process in which is performed.
In step B130, automatic stop position estimation is performed. The automatic stop position estimation means that the automatic stop position estimation means 170 estimates the stop position of each rotary reel 40 when the stop control by the automatic stop control means 160 is performed. Then, the process proceeds to Step B140.

In step B140, a winning estimation is performed. Winning estimation is to determine whether or not the stop position of each rotary reel 40 estimated by the automatic stop position estimating means 170 is a stop position at which a predetermined symbol arrangement is displayed, by the winning estimation means 190. It is. In the winning guess, it is presumed that a BB winning or other winnings will be made, or none of them will be won. Then, the process proceeds to Step B150.
In step B150, a determination is made as to whether or not a BB prize is expected based on the guess result of the winning guess. Here, if it is determined that a BB winning is made, the process proceeds to step B160. On the other hand, if it is determined that another winning or no winning is made, the process proceeds to step B170.

In step B160, an automatic stop effect is performed. The automatic stop effect is to perform an effect on the liquid crystal display 79 before the player's stop operation based on the estimation result of the automatic stop position estimating means 170. Then, the process proceeds to Step B180.
In step B170, normal performance processing is performed. The normal effect process is to determine whether or not to perform a normal effect, what kind of effect to perform when performing a normal effect, and the like, and to perform an effect based on the determination. The normal effect is an effect performed based on the lottery result of the role lottery means 110 and the selected stop table. Then, the process proceeds to Step B180.
In step B180, reel rotation start processing is performed. The reel rotation start process is a process of starting rotation of each rotary reel 40 by the rotation control means 120. Then, the process proceeds to Step B190.

In step B190, it is determined whether or not the stop switch 60 has been operated by the player. Here, if it is determined that the player has operated the stop switch 60, the rotary reel 40 corresponding to the operated stop switch 60 is stopped, and the process proceeds to Step B200. On the other hand, if it is determined that the player has not operated the stop switch 60, the process proceeds to step B260.
In Step B200, it is determined whether there is a rotating reel 40 that is rotating. If it is determined that there is a rotating reel 40 that is rotating, the process proceeds to step B210. On the other hand, if it is determined that all the rotating reels 40 have already stopped and there are no rotating reels 40 that are rotating, the process proceeds to step B280.

In step B210, the automatic stop position is estimated again. Then, the process proceeds to Step B220.
In step B220, the winning guess is re-established based on the estimated result of the automatic stop position estimating means 170 that has been estimated again. Then, the process proceeds to Step B230.
In step B230, it is determined whether or not it is expected to win a BB as a result of re-estimating the winning. Here, if it is determined that a BB winning is made, the process proceeds to step B240. On the other hand, if it is determined that another winning or no winning is made, the process proceeds to step B250.

In step B240, an automatic stop effect is performed based on the estimation result of the automatic stop position estimating means 170 that has been re-estimated. Then, returning to step B190, it is determined whether or not the stop switch 60 has been operated.
In step B250, normal performance processing is performed. Then, the process returns to step B190 to determine whether or not the stop switch 60 has been operated.
In step B260, it is determined whether 31 seconds have elapsed since the operation of the stop switch 60 was enabled. If it is determined that 31 seconds have elapsed, the process proceeds to step B270. On the other hand, if it is determined that 31 seconds have not elapsed, the process returns to step B190 to determine whether or not the stop switch 60 has been operated.

In step B270, automatic stop control is performed. The automatic stop control is to perform stop control by the automatic stop control means 160. Then, the process proceeds to Step B280.
In step B280, game processing is performed. The game process is to perform determination by the winning determination unit 150 or to pay out coins based on the determination. Then, the automatic stop effect ends.
Thus, in the present embodiment, the result of the stop control by the automatic stop control means 160 is estimated. Further, when it is presumed that the result of the stop control by the automatic stop control means 160 will be a BB prize, an effect is given on the liquid crystal display 79 based on the estimation result before the player's stop operation. Then, even a player who is unfamiliar with the game can stop each rotating reel 40 so as to display the symbol arrangement for the BB prize. In addition, even players who are unfamiliar with the game have extra restrictions on the types and arrangement of symbols attached to the rotating reels 40 in order to stop the rotating reels 40 so that the symbol arrangements for winning the BB prize are displayed reliably. There is no need to add.

Further, in the present embodiment, the automatic stop position estimating means 170 performs the estimation almost simultaneously with the operation of the start switch 50 by the player, and the automatic stop effecting means 200 produces an effect based on the estimation result. Then, almost simultaneously with the operation of the start switch 50 by the player, the result of the stop control by the automatic stop control means 160 can be known, so that the player can quickly determine whether or not the stop operation should be performed.
Further, in the present embodiment, as a result of the stop control by the automatic stop control means 160, an effect based on the estimation result is performed only when the greatest profit is given to the player. By doing so, the expectation for the production increases.

In the present embodiment, the estimation by the automatic stop position estimating means 170 is performed only when the lottery result by the winning lottery means 110 is BB winning so that the estimation by the automatic stop position estimating means 170 may be performed less frequently. To do.
In the present embodiment, the rotation of the rotary reel 40 is started after the presentation is performed. However, the presentation may be performed after the rotation of the rotary reel 40 is started.
(Third embodiment)
(Explanation of drawings)
12 and 13 show a third embodiment.

FIG. 12 is a block diagram of the automatic stop position estimating means 170, and FIG. 13 is a flowchart showing the operation of the slot machine 10.
In the first embodiment, each rotary reel 40 is rotated, and the estimation by the automatic stop position estimating means 170 is performed when the operation of the stop switch 60 becomes valid. However, the third embodiment Then, the estimation by the automatic stop position estimation means 170 is performed before the rotation of each rotary reel 40 is started.
The slot machine 10 according to the present embodiment is the same as that of the first embodiment except for the rotation control means 120 and the automatic stop position estimating means 170. Therefore, in the present embodiment, the description will focus on the rotation control means 120 and the automatic stop position estimation means 170, and the description of the components other than the rotation control means 120 and the automatic stop position estimation means 170 will be omitted.

(Rotation control means 120)
The rotation control means 120 is for controlling the rotation of each rotary reel 40.
Similar to the rotation control means 120 in the first embodiment, the rotation control means 120 in the present embodiment starts the rotation of each rotary reel 40 based on the operation of the start switch 50 and causes each rotary reel 40 to move. Acceleration processing for accelerating rotation is performed, and when the rotational speed reaches a predetermined speed, the acceleration processing is terminated, and constant speed processing for rotating each rotating reel 40 at a constant speed is performed to keep the rotational speed constant. .
Similarly to the first embodiment, in this embodiment, a stepping motor 35 having a four-phase basic step angle of 1.43 degrees is employed as power for rotating the rotary reel 40. In the present embodiment, the constant speed process and the acceleration process are also performed in the same manner as in the first embodiment, and thus detailed description thereof is omitted.

Hereinafter, rotation control of each rotary reel 40 in the present embodiment will be described.
Similar to the first embodiment, also in this embodiment, when the player operates the start switch 50, the rotation control means 120 first waits until 175 ms elapses. When 175 ms has elapsed, the rotation control means 120 detects whether 4.1 seconds have elapsed since the previous game ended.
When 175 ms has elapsed since the start switch 50 was operated and 4.1 seconds have elapsed since the end of the previous game, the rotation control means 120 immediately starts the rotation of the rotating reels 40 simultaneously. In addition, a pulse for starting the rotation of each rotary reel 40 is output.

On the other hand, when 175 ms has elapsed from the start switch 50 operation and 4.1 seconds have not elapsed since the previous game ended, the rotation control means 120 has passed 4.1 seconds since the previous game ended. Then, a pulse for starting the rotation of each rotary reel 40 is output so that the rotation of each rotary reel 40 is started simultaneously.
Then, acceleration processing is performed for each rotating reel 40 in order to gradually increase the rotation speed. When the speed of each rotary reel 40 reaches one rotation speed in 750 ms by the acceleration process, the acceleration process ends. Then, in order to keep each rotating reel 40 rotating at a speed of one rotation at 750 ms, constant speed processing is performed with a constant interval at which one pulse is output.

(Automatic stop position estimation means 170)
Similar to the automatic stop position estimating means 170 in the first embodiment, the automatic stop position estimating means 170 in the present embodiment is controlled to stop by the rotational position of each rotary reel 40 and the automatic stop control means 160. Based on the number of pulses output so far, when the stop control is performed by the automatic stop control means 160, the stop position where each rotary reel 40 will stop is estimated in advance.
In the present embodiment, the automatic stop position estimating means 170 performs estimation based on the stop position of each rotary reel 40 in the previous game when the player operates the start switch 50.

In the present embodiment, as shown in FIG. 12, the automatic stop position estimating means 170 includes a previous stop position storage means 171, an acceleration end position calculating means 173, and a reference position pre-detection output pulse calculating means 174. , Reference position elapsed time calculating means 175, operation effective timing calculating means 176, operation effective elapsed time calculating means 177, pre-operation effective output pulse calculating means 178, operation effective position calculating means 179, automatic stop Elapsed time before start calculating means 181, output pulse calculating means 182 before starting automatic stop, automatic stop start position calculating means 183, output pulse calculating means during automatic stop 184, and automatic stop position calculating means 185 are provided. .
The previous stop position storage means 171 is for storing the stop position of each rotary reel 40 in the previous game. The previous stop position storage means 171 stores the stop position of each rotary reel 40 detected by the rotational position detection means 130 when the rotation of all the rotary reels 40 is stopped in the previous game.

The acceleration end position calculating means 173 is for calculating the acceleration end position of each rotary reel 40 based on the stop position in the previous game. The acceleration end position is a rotation position at the end of the acceleration process in each rotary reel 40. Also in the present embodiment, the acceleration process of each rotating reel 40 is terminated by outputting 23 pulses in 125 ms, so the acceleration ending position of each rotating reel 40 is output from the stop position in the previous game. The rotation position.
Further, the output pulse calculation means 174 before reference position detection is for calculating the number of output pulses before reference position detection in each rotary reel 40. The number of output pulses before detecting the reference position is the number of pulses output from the end of acceleration processing to the first output of the index signal after the end of acceleration processing in each reel 40. The pre-reference position detection output pulse calculation means 174 calculates the number of output pulses before the reference position detection by calculating the number of pulses necessary for each rotating reel 40 to become the next reference position from the acceleration end position. .

  The reference position elapsed time calculation means 175 is for calculating the elapsed time before reference position detection in each rotary reel 40. The elapsed time before reference position detection is the time that elapses between the end of the acceleration process and the first output of the index signal after the end of the acceleration process in each rotary reel 40. Also in this embodiment, the interval at which one pulse is output is constant. Therefore, the elapsed time before reference position detection calculating means 175 outputs the number of output pulses before reference position detection for each rotating reel 40 based on the number of output pulses before reference position detection and the interval at which one pulse is output. The time required to perform the calculation, that is, the time that elapses from when the acceleration process is completed until the first index signal is output is calculated.

  The operation effective timing calculation means 176 is for calculating the operation effective timing. The operation effective timing is a timing at which the operation of the stop switch 60 becomes effective. Also in the present embodiment, the index signal is output after the acceleration processing has been completed for all the rotating reels 40, and when 700 ms has elapsed since all the rotating reels 40 started rotating, the stop switch 60 The operation becomes valid. Therefore, there is a condition that an acceleration signal is finished in each rotary reel 40 and an index signal is output after the acceleration process is finished, and a condition that 700 ms elapses after all the rotary reels 40 start to rotate. When all are satisfied, the operation of the stop switch 60 becomes effective. The operation effective timing calculation means 176 indicates that the timing at which the index signal is output after the acceleration process is completed and the acceleration process is completed for each rotating reel 40, and 700 ms have elapsed since all the rotating reels 40 started rotating. The timing at which these conditions are satisfied and the operation of the stop switch 60 becomes valid can be calculated by comparing with the timing to perform. In other words, the operation effective timing calculation means 176 calculates the index signal after the acceleration process is completed from the time when each rotary reel 40 starts rotating based on the time 125 ms required for the acceleration process and the elapsed time before the reference position has elapsed. The time until output is calculated. Further, the operation effective timing calculation means 176 compares these times with 700 ms, and determines the time when all the conditions are satisfied, that is, the latest time satisfying the conditions among these times, by operating the stop switch 60. As the timing when becomes effective.

Further, the pre-operation effective elapsed time calculating means 177 is for calculating the pre-operation effective elapsed time for each rotary reel 40. The elapsed time before the operation is effective is the time that elapses from when the acceleration process of the rotary reel 40 is completed until the operation of the stop switch 60 becomes effective. The pre-operation effective elapsed time calculation means 177 calculates the pre-operation effective elapsed time based on the operation effective timing and the time 125 ms from when each rotating reel 40 starts rotating to when the acceleration process ends.
The pre-operation effective output pulse calculation means 178 is for calculating the number of output pulses before the operation effective in each rotary reel 40. The number of output pulses before the operation is the number of pulses output from the end of the acceleration process of each rotary reel 40 until the operation of the stop switch 60 becomes effective. The pre-operation effective output pulse calculation means 178 calculates the number of pulses that are output during the elapse of the pre-operation effective time based on the elapsed time before the operation effective and the interval at which one pulse is output.

The operation effective position calculation means 179 is for calculating the operation effective position. The operation effective position calculation means 179 calculates the operation effective position based on the acceleration end position and the number of output pulses before operation effective. That is, the rotation position that is located when the number of pulses before the operation is effective is output from the acceleration end position as the operation effective position of each rotary reel 40.
Also in the present embodiment, automatic stop start elapsed time calculation means 181, automatic stop start output pulse calculation means 182, automatic stop start position calculation means 183, automatic stop output pulse calculation means 184, automatic stop position calculation Since the means 185 has the same configuration as that of the first embodiment, the description thereof is omitted.

In the present embodiment, even if the player operates the stop switch 60, the estimation by the automatic stop position estimating means 170 is not repeated.

Here, if it is determined that the lottery result of the combination lottery means 110 is BB winning, the process proceeds to step C130. On the other hand, if it is determined that the lottery result of the combination lottery means 110 is not BB winning, the process proceeds to step C170.
In step C130, automatic stop position estimation is performed. The automatic stop position estimation means that the automatic stop position estimation means 170 estimates the stop position of each rotary reel 40 when the stop control by the automatic stop control means 160 is performed. Then, the process proceeds to Step C140.

In step C140, a winning prediction is performed. Winning estimation is to determine whether or not the stop position of each rotary reel 40 estimated by the automatic stop position estimating means 170 is a stop position at which a predetermined symbol arrangement is displayed, by the winning estimation means 190. It is. In the winning guess, it is presumed that a BB winning or other winnings will be made, or none of them will be won. Then, the process proceeds to Step C150.
In step C150, a determination is made as to whether or not a BB prize is expected based on the guess result of the prize guess. Here, if it is determined that a BB winning is made, the process proceeds to step C160. On the other hand, if it is determined that any other winning or no winning is made, the process proceeds to step C170.

In step C160, an automatic stop effect is performed. The automatic stop effect is to perform an effect on the liquid crystal display 79 before the player's stop operation based on the estimation result of the automatic stop position estimating means 170. Then, the process proceeds to Step C180.
In step C170, normal effect processing is performed. The normal effect process is to determine whether or not to perform a normal effect, what kind of effect to perform when performing a normal effect, and the like, and to perform an effect based on the determination. The normal effect is an effect performed based on the lottery result of the role lottery means 110 and the selected stop table. Then, the process proceeds to Step C180.
In step C180, reel rotation start processing is performed. The reel rotation start process is a process of starting rotation of each rotary reel 40 by the rotation control means 120.
Then, the automatic stop effect ends.

Thus, in the present embodiment, the result of the stop control by the automatic stop control means 160 is estimated. Further, when it is presumed that the result of the stop control by the automatic stop control means 160 will be a BB prize, an effect is given on the liquid crystal display 79 based on the estimation result before the player's stop operation. Then, even a player who is unfamiliar with the game can stop each rotating reel 40 so as to display the symbol arrangement for the BB prize. In addition, even players who are unfamiliar with the game have extra restrictions on the types and arrangement of symbols attached to the rotating reels 40 in order to stop the rotating reels 40 so that the symbol arrangements for winning the BB prize are displayed reliably. There is no need to add.

Further, in the present embodiment, the automatic stop position estimating means 170 performs the estimation almost simultaneously with the operation of the start switch 50 by the player, and the automatic stop effecting means 200 produces an effect based on the estimation result. Then, almost simultaneously with the operation of the start switch 50 by the player, the result of the stop control by the automatic stop control means 160 can be known, so that the player can quickly determine whether or not the stop operation should be performed.
Further, in the present embodiment, as a result of the stop control by the automatic stop control means 160, an effect based on the estimation result is performed only when the greatest profit is given to the player. By doing so, the expectation for the production increases.

In the present embodiment, the estimation by the automatic stop position estimating means 170 is performed only when the lottery result by the winning lottery means 110 is BB winning so that the estimation by the automatic stop position estimating means 170 may be performed less frequently. To do.
In the present embodiment, the rotation of the rotary reel 40 is started after the presentation is performed. However, the presentation may be performed after the rotation of the rotary reel 40 is started.

In the above embodiment, the production by the automatic stop production means 200 is performed when it is estimated that the BB prize is won. You may make it produce an effect. Further, as another form, the production by the automatic stop production means 200 may be produced when any winning is made. When the former is used, it is understood that if the player performs stop control by the automatic stop control means 160, a greater profit than usual is given, and the sense of expectation increases. Further, if the latter is used, it is understood that if the player performs stop control by the automatic stop control means 160, some benefit is given, and the expectation increases.

In the above embodiment, when the estimation result by the winning estimation means 190 is a BB winning, the automatic stop effecting means 200 is performed. However, the lottery is performed regardless of whether the winning is predicted or not. It is good also as what determines whether to produce by. In addition, when it is predicted that a predetermined prize will be won, it may be determined by lottery whether or not to produce an effect.
Further, in the above-described embodiment, the winning guessing unit 190 guesses which winning will be won, but it may be possible to guess only whether or not it will be a BB winning. Moreover, you may make it guess only whether it becomes BB or RB winning. Further, it may be estimated only whether or not the winning is related to the effect by the automatic stop effect means 200.

Further, in the above embodiment, the condition for the stop control by the automatic stop control means 160 is 31 seconds after the player can perform the stop operation, but after a predetermined time has elapsed since the predetermined time. If the conditions are determined in advance, the rotation reel 40 may rotate after a predetermined number of rotations from a predetermined rotation position or after a predetermined number of pulses are output.
Further, in the above embodiment, when the stop switch 60 corresponding to any of the rotary reels 40 is operated by the player, the estimation by the automatic stop position estimating means 170 is performed again. Only when the stop control by the automatic stop control means 160 is performed on 40, the estimation by the automatic stop position estimation means 170 or the presentation by the automatic stop presentation means 200 may be performed. Further, only when the stop switch 60 corresponding to some of the rotating reels 40 is operated and the stop control by the automatic stop control unit 160 is performed on some of the rotating reels 40, the estimation by the automatic stop position estimating unit 170, Alternatively, an effect by the automatic stop effect means 200 may be performed.
