Description

  The present invention relates to a slot machine having a plurality of stop switches and capable of stopping a reel by operating the plurality of stop switches.

  In the conventional slot machine, when there are a plurality of stop switches corresponding to each of the plurality of reels, it may be operated from any stop switch.

For example, in a slot machine having three reels, a left reel, a middle reel, and a right reel, a left stop switch corresponding to the left reel is provided, a middle stop switch corresponding to the middle reel is provided, and the right reel A corresponding right stop switch is provided. In this case, it is a common operation to operate the three stop switches in the order of “left” → “middle” → “right” to stop the three reels, but “left” → “right” → “ It was possible to stop the three reels by operating in the order of “middle” or in the order of “right” → “middle” → “left” (for example, see Patent Document 1).
JP 2002-155357 A

  However, in conventional slot machines, it was often assumed that the three stop switches were operated in the order of “left” → “middle” → “right”, so “left” → “middle” → “right” If the game is operated in an order other than “”, the game result may be different from that operated in the order “left” → “middle” → “right”.

  For example, when the game is operated in the order of “left” → “middle” → “right”, the game result corresponding to the lottery result can be changed, but the order other than “left” → “middle” → “right” When operated in order, a game result corresponding to the lottery result could not be obtained.

  In addition, when the three stop switches are operated in the order of “left” → “middle” → “right”, the three stop switches are controlled even though the three reels can be stopped and controlled so as not to be repeatedly won. When the player is operated in an order other than "Left"-> "Middle"-> "Right", the player is required to stop and control the three reels so as not to make double winnings as a result of the lottery process. Depending on the operation timing of the stop switch, there was a case where it was necessary to stop the three reels so as to make double winning.

  When the three reels are stopped and controlled so as to win multiple times in this way, the number of payouts for the inserted medals will be different from the expected one, so that the number of payouts can be sufficiently controlled. It was gone.

  Furthermore, even if the three stop switches are operated in an order other than “left” → “middle” → “right”, an arrangement of symbols arranged on each of the three reels in order to avoid double winning It is possible to avoid double winnings by changing. However, when doing so, the arrangement of symbols that can be placed on the three reels is limited, the combination of symbols that can be arranged on the effective line is also limited, the game itself is limited, and the game is not interesting It became.

  The present invention has been made in view of the above-described points, and an object of the present invention is to make it possible to accurately control the number of payouts for inserted medals by making the reel stop control preferable. It is an object of the present invention to provide a slot machine that can increase the degree of freedom of arrangement of symbols to be arranged.

  In order to achieve the above object, in the present invention, after satisfying a predetermined condition after starting the rotation control, only the stop switch corresponding to the predetermined one reel is made effective, and the predetermined one Disable the stop switch corresponding to all reels other than the reel.

Specifically, the slot machine according to the present invention is:
A slot machine that rotates or stops based on a player's operation and includes a plurality of reels each having a plurality of types of symbols,
An operation means including a start switch that emits a start signal based on the player's operation, and a stop switch that emits a stop signal based on the player's operation;
Reel control means for controlling the rotation of the plurality of reels based on the start signal, and controlling the stop of the plurality of reels based on the stop signal, and
The reel control means includes
One of valid processing for enabling the stop control by validating the stop signal issued from the stop switch, and invalid processing for maintaining the rotation control by invalidating the stop signal issued from the stop switch Valid / invalid selection means for selecting the processing of,
After satisfying a predetermined condition from the start of the rotation control, the effective processing is performed on a stop switch corresponding to a predetermined one of the plurality of reels, and among the plurality of reels And performing the invalidation process on stop switches corresponding to all reels other than the predetermined one reel,
And valid / invalid stop control means for performing the valid process on stop switches corresponding to all the other reels when the predetermined one reel is stopped.

  According to the above-described invention, after the rotation control is started and a predetermined condition is satisfied, the effective process is performed on a stop switch corresponding to a predetermined one of the plurality of reels, and Since the invalidation processing is performed on the stop switches corresponding to all the reels other than the predetermined one reel among the plurality of reels, the stop switch that can be stopped first by the player Can be limited to only stop switches corresponding to a predetermined reel.

  By limiting in this way, the order of stopping the reels can also be limited, so that the reel stop control can be performed so as to obtain a game result corresponding to the lottery result by the lottery means. It can be controlled accurately. Further, since the reel stop control can be accurately performed, the arrangement of symbols arranged on the reel is not limited, the degree of freedom of the symbol arrangement can be increased, and the fun of the game can be enhanced.

  Further, the reel stop control is performed with reference to the data stored in the stop control table. For this reason, in order to accurately stop the reels, it is necessary to determine and store stop control table data for all combinations in the order of stopping the plurality of reels. However, according to the above-described invention, the stop switch that can be stopped first is only the stop switch corresponding to the predetermined one reel, so that it is necessary to stop the predetermined one reel first. Since only the data needs to be stored in the stop control table, the storage capacity of the stop control table can be reduced.

  The invalidation process described above does not recognize the effect that the stop signal is issued even if the stop signal is issued from the stop switch, and ignores the fact that the stop signal is issued even if the stop signal is detected. This is a process for not allowing the originally scheduled operation when the stop signal is issued. Accordingly, the invalidation process only performs a process that does not permit the originally scheduled operation.

  In addition, when the stop signal is issued when the stop signal is issued from the stop switch, when the stop signal is detected when the stop signal is issued, This is a process for permitting the originally scheduled operation. Therefore, the valid process only performs the process of permitting the originally scheduled operation, and the originally scheduled operation is not always executed as soon as the valid process is performed.

  Here, the originally scheduled operation in the valid process or invalid process is to stop control of the reel corresponding to the stop switch operated by the player.

  Further, when one of the stop switches corresponding to all the other reels is operated by the player when the predetermined one reel is stopped, it corresponds to the stop switch operated by the player. It is preferable that the reel stops.

  After the predetermined one reel stops, if the player operates any of the stop switches corresponding to all the other reels, the reel corresponding to the stop switch operated according to the operation is stopped. Can be made. After the predetermined one reel is stopped, the order of stopping all the other reels can be determined by the player's intention, and the player's intention can be reflected.

  Furthermore, it is preferable that the invalidation processing is performed on all of the stop switches corresponding to the plurality of reels until the predetermined condition is satisfied after the rotation control is started.

  From the start of the rotation control until the predetermined condition is satisfied, any of the stop switches corresponding to the plurality of reels cannot be stopped, and the order in which the stop switches can be operated is predetermined. It can be in a state that is a premise to limit to.

  Furthermore, it is preferable that the predetermined one reel is provided with a single winning symbol.

  In this way, when the player first stops the reel, if the single winning symbol wins, the winning of the single winning symbol can be confirmed at that time.

In addition, lottery means for determining winning or losing as a lottery result by lottery processing,
Stop information storage means for storing first stop information and second stop information which are determined so as to be a display mode of a symbol corresponding to the lottery result when the reel stops, And,
It is preferable that one of the first stop information and the second stop information is selected according to the order in which the plurality of reels stop.

  By doing in this way, stop control can be accurately performed according to the order in which the stop switch is operated.

  Even if the order in which a plurality of stop switches are operated by a player is different, it is possible to control the stop of the reels so that a game result corresponding to the lottery process is obtained, and the arrangement of symbols arranged on the reels The degree of freedom can also be increased. Furthermore, the storage capacity of the stop control table required for reel stop control can be reduced.

Embodiments of the present invention will be described below with reference to the drawings.

<Games in the slot machine 10>
A game in the slot machine 10 is a game in which a game result is determined by a combination of symbols determined by stop positions of the plurality of stopped reels 30L, 30C, or 30R. The player operates the three stop switches 44a, 44b and 44c so that the combination of symbols to be stopped on the active line becomes a combination of symbols constituting a predetermined role, and turns the reels 30L, 30C or 30R. Stop. In addition, a game performed in the slot machine 10 is performed each time the player operates the start switch 42, and a game that can be repeated as a single process from the start of rotation to the stop of rotation of the plurality of reels 30L, 30C, or 30R. It is. This single-stroke game is called a unit game.

  The types of the above-described combinations include, for example, special combinations, small combinations, and replay combinations. The special role is a role that can shift from a normal game to a special game (a game advantageous to the player). The special combination includes a big bonus (hereinafter referred to as BB combination) and a regular bonus (hereinafter referred to as RB combination).

  The above-mentioned BB combination is a combination to shift to a BB game which is one of special games. This BB game is a game that can be transferred to a privilege game a plurality of times. This privilege game is a game that performs a game in which a predetermined role is won with high probability, and is a game that can give a player a privilege that increases the possibility that the player will acquire more medals. In this BB game, the privilege game can be repeated until a predetermined end condition is satisfied, for example, until the number of medals to be paid out exceeds a predetermined number.

  In addition, the RB combination is a combination to shift to the RB game that is one of the special games. This RB game is a game in which a game corresponding to a privilege game during the BB game is played, that is, a game in which a predetermined role is won with a high probability is performed a predetermined number of times under a certain condition.

  Further, the small combination is a combination for paying out a predetermined number of medals. A small role has a plurality of types of roles, and the name of the role is often used by using the types of symbols attached to the three reels 30L, 30C, or 30R. For example, the types of symbols include “watermelon”, “bell”, “cherry” and the like. For this reason, a small role in which the pattern “watermelon” is aligned on the effective line is referred to as a watermelon role, and a small role in which the pattern “bell” is aligned on the effective line is referred to as a bell role. Further, when the symbol “cherry” of the left reel 30L is stopped and displayed on the active line, it is assumed that a winning is made regardless of the types of symbols of the middle reel 30C and the right reel 30R. This role is called the cherry role. Further, the symbol “cherry” of the “cherry role” is a symbol that determines whether or not the symbol alone has been won, and is therefore referred to as “single winning symbol”.

  Furthermore, the re-game role is a role that allows a re-game (hereinafter referred to as “replay” or “RP”) that maintains the number of bets (the number of bets) in the currently played game.

<< Functions of Slot Machine 10 >>
FIG. 3 is a functional block diagram showing an outline of main control functions in the slot machine 10. As shown in FIG. 3, the slot machine 10 mainly includes an operation unit 500, a main control unit 100, and a symbol display unit 400.

The operation means 500 preferably includes a start switch 42 and stop switches 44a to 44c. When the start switch 42 is operated by the player, the start switch 42 issues a signal indicating that the start switch 42 has been operated to the main control means 100 described later. Further, when each of the stop switches 44a to 44c is operated by the player, the stop switch 44a to 44c issues a signal indicating that it has been operated to the main control means 100 described later.

  As described above, a single process game that is performed after a plurality of reels 30L, 30C, or 30R is rotated and then stopped is referred to as a unit game. The signals issued from the start switch 42 to the main control means 100 start the rotation of the three reels 30L, 30C and 30R, thereby determining the start timing of the unit game. A signal issued from the start switch 42 to the main control means 100 is referred to as a start signal.

  In addition, the corresponding reels among the three reels 30L, 30C, and 30R are stopped by a signal issued from each of the stop switches 44a to 44c to the main control means 100, and a trigger for ending the unit game is determined. A signal issued from each of the stop switches 44a to 44c to the main control means 100 is referred to as a stop signal. Accordingly, the unit game is started based on the start signal being issued and the unit game is ended based on the stop signal being issued.

  There are a plurality of types of operation modes for operating the three stop switches 44a to 44c. For example, the three stop switches 44a to 44c can be operated in different order and operation timing. Specifically, the operation can be performed in a different order, such as stop switch 44a → 44b → 44c and 44a → 44c → 44b. Further, the three stop switches 44a to 44c can be operated at a timing at which a specific symbol is positioned on the effective line, or can be operated at a timing unrelated to the symbol position. Thus, the player can operate the three stop switches 44a to 44c in a plurality of types of operation modes.

  As described above, a stop signal is issued from each of the stop switches 44a to 44c to the main control means 100, and there are a plurality of types of operation modes for operating the stop switches 44a to 44c. For this reason, the stop signal is issued based on the operation mode, and the main control unit 100 that generates the stop signal obtains the operation mode by detecting the order in which the stop signal was issued and the timing at which the stop signal was issued. be able to.

  Further, the number of medals to be a game bet is determined by a signal issued from the 1-bet switch 62, 2-bet switch 64 or maximum bet switch 66 to the main control means 100. For example, one medal is targeted for a game bet by a signal issued from the 1 bet switch 62 to the main control unit 100, and two medals are received by a signal issued from the 2 bet switch 64 to the main control unit 100. Are bets for gaming, and three medals are targeted for gaming bets by a signal issued from the maximum bet switch 66 to the main control means 100.

<Main control means 100 (game control means)>
In addition to the operation means 500 described above, the symbol display means 400 is electrically connected to the main control means 100. The main control means 100 controls the entire game such as the progress of the game and issues a control signal to the symbol display means 400. The main control means 100 preferably comprises the main control board 32 described above.

  As described above, the operation means 500 is electrically connected to the main control means 100. A stop signal is issued to the main control unit 100 from each of the stop switches 44 a to 44 c of the operation unit 500. By detecting the order and timing of stop signals issued from each of the stop switches 44a to 44c, the main control means 100 can obtain a plurality of types of operation modes of the three stop switches 44a to 44c.

  The main control means 100 is composed of a combination lottery means 120, a reel drive control means 130, and a symbol detection means 150.

<Role lottery means 120 (lottery means)>
The role lottery means 120 performs a lottery of a predetermined role. As described above, the combination includes a special combination, a small combination, and a replay combination.

  The special role is a role that shifts from the normal game to the special game. A special game is a game that has a higher possibility of acquiring more medals than the number of medals that can be acquired in a normal game, and is a game that is advantageous to the player. In general, the special combination includes a BB combination (Big Bonus) and an RB combination (Regular Bonus). These BB combination or RB combination is a combination to shift to BB game or RB game, which is one of special games.

  The small combination is a combination in which a predetermined number of medals are paid out. As described above, there are a plurality of types of small roles such as a watermelon role, a bell role, and a cherry role. When a small combination is drawn by lottery processing, one type of small combination is determined. The number of medals to be paid out is preset in accordance with the type of the small role.

  Furthermore, the re-game player can play the current game while maintaining the number of medals inserted in the previous game (the number of bets), that is, a player who can play the game again. is there.

  The role lottery means 120 includes, for example, a random number generation means 122, a random number extraction means 124, and a random number determination means 126. The random number generation means 122 generates a random number for a lottery (such as a hardware random number). The random number extraction unit 124 extracts the random number generated by the random number generation unit 122. The random number determination means 126 determines the presence / absence of a winning combination and the winning combination based on the random number value extracted by the random number extracting means 124. The role lottery means 120 constitutes “lottery means”, and “lottery processing” is performed.

  The “lottery process” is a lottery process for determining whether a game is won or missed. Specifically, it is executed in step S13 of FIG.

<Random number generator 122>
The random number generator 122 continuously generates random numbers in a predetermined positive integer range (for example, 0 to 65535 in decimal notation) at predetermined timings.

<Random number extraction means 124>
The random number extraction unit 124 extracts the random number generated by the random number generation unit 122 at a predetermined timing. For example, in the present embodiment, random numbers are extracted when the start switch 42 is operated by the player.

<Random number judging means 126>
The random number judging unit 126 collates the random number value extracted by the random number extracting unit 124 with a probability table stored in a judgment collation data storage unit (not shown), thereby corresponding to the region to which the random number value belongs. To decide.

  There are a plurality of types of probability tables, for example, a normal game probability table and a replay high probability game probability table. The normal game probability table is selected and referred to when a lottery process is performed when a normal game is being performed. The replay high probability game probability table is selected and referred to when a lottery process is performed when a replay high probability game is being performed. The area for defining the re-gamer in the replay high probability game probability table is set larger than the area for defining the re-gamer in the normal game probability table. By doing so, the probability of winning a re-gamer when a replay high-probability game is being played is made higher than the predetermined probability of winning a re-game player when a normal game is being played. be able to.

  It is assumed that “winning” is selected by the role lottery means 120 when the above-mentioned role lottery means 120 wins the BB role, the RB role, the bell role, the watermelon role, the cherry role, or the replaying role. Further, it is assumed that when the lottery process results in a winning that is not the above-mentioned winning combination, “losing” is selected by the winning lottery means 120.

<Reel drive control means 130>
The reel drive control unit 130 performs rotation control and stop control of the three reels 30L to 30R based on the start signal issued from the start switch 42 and the stop signal issued from the stop switches 44a to 44c. . The reel drive control unit 130 includes a reel rotation control unit 132 and a reel stop control unit 134. The reel drive control means 130 constitutes “reel drive control means”.

<Reel rotation control means 132>
The reel rotation control means 132 issues a rotation control signal to the motors 86a, 86b and 86c when it detects a start signal issued from the operation means 500, preferably the start switch 42 described above. As will be described later, the motor 86a drives the left reel 30L, the motor 86b drives the middle reel 30C, and the motor 86c drives the right reel 30R. When the reel rotation control means 132 detects the start signal, it issues a rotation control signal to these three motors 86a, 86b and 86c. With the rotation control signal, the three reels 30L to 30R start to rotate. This process is executed in step S14 of a subroutine shown in FIG.

<Reel stop control means 134>
The reel stop control means 134 issues a stop control signal to the motor 86a, 86b or 86c when detecting a stop signal issued from the operation means 500 described above, preferably from the stop switches 44a to 44c. As described above, the left reel 30L corresponds to the stop switch 44a, the middle reel 30C corresponds to the stop switch 44b, and the right reel 30R corresponds to the stop switch 44c. That is, when a stop signal is issued from the stop switch 44a, the reel stop control means 134 issues a stop control signal to the motor 86a that drives the left reel 30L to stop the left reel 30L. When a stop signal is issued from the stop switch 44b, a stop control signal is issued to the motor 86b that drives the middle reel 30C to stop the middle reel 30C. Further, when a stop signal is issued from the stop switch 44c, a stop control signal is issued to the motor 86c that drives the right reel 30R to stop the right reel 30R. These processes are executed in step S15 of a subroutine shown in FIG.

  Specifically, the reel stop control unit 134 detects a symbol by a symbol detection unit 150 (to be described later) when any one of the stop switches 44a, 44b or 44c in the operation unit 500 is operated. The reel corresponding to the stop switch operated based on the rotation amount information corresponding to the symbol is stopped.

  Here, the rotation amount information is information stored in a stop control table 135 to be described later, and is operated thereafter based on the rotation position of the reels 30L to 30R when the stop switch 44a, 44b or 44c is operated. This is information indicating the amount corresponding to the angle to be rotated until the reel corresponding to the stop switch is rotated. Here, the rotation position of the reels 30L to 30R when the stop switch 44a, 44b, or 44c is operated is the position at the above-described fixed rotation reference position. Further, the rotation amount stored in the stop control table 135 may indicate the amount by which the reels 30L, 30C, or 30R rotate, and need not be a specific angle or a length along the circumferential direction. For example, it is preferable to use the number of symbols of the symbol as the rotation amount.

  That is, the reel stop control unit 134 detects the symbol by the symbol detection unit 150 when one of the stop switches 44a, 44b, or 44c of the operation unit 500 is operated, and refers to the stop control table 135. Then, the number of sliding frames is obtained, the reels 30L, 30C, or 30R corresponding to the stop switch operated by the number of frames are moved, and then the reels are stopped.

  The reel stop control means 134 is configured such that when the above-described random number determination means 126 refers to a game probability table (not shown) based on the random number value and the winning combination is determined, the winning combination is won. Then, stop control of the three reels 30L, 30C and 30R is performed.

  Further, as described above, the main control means 100 can obtain the type of operation mode by detecting the order and timing of stop signals issued from the stop switches 44a to 44c. The reel stop control means 134 controls the stop of the three reels 30L, 30C and 30R based on the type of operation mode obtained.

  Furthermore, when any of the winning combinations is won, when the three stop switches 44a to 44c are operated at a timing such that a specific symbol corresponding to the winning combination can be positioned on the effective line, the reel stop control means 134 actively controls stop of the three reels 30L, 30C and 30R so that a specific symbol is positioned on the effective line. On the other hand, when the three stop switches 44a to 44c are operated at a timing at which a specific symbol corresponding to the combination cannot be positioned on the active line even if a certain combination is won, The reel stop control means 134 controls the stop of the three reels 30L, 30C, and 30R so that a specific symbol is not positioned on the effective line.

  In this way, the reel stop control means 134 also controls the stop of the three reels 30L, 30C, and 30R based on the type of operation mode obtained from the stop signal generated from each of the stop switches 44a to 44c.

<Stop control table 135>
The stop control table 135 stores rotation amount information. As described above, the rotation amount information is based on the rotation position of the reels 30L to 30R when the stop switch 44a, 44b or 44c is operated, and then the reel corresponding to the operated stop switch is stopped. This is information indicating the amount corresponding to the angle of rotation. Similarly to the stop information described above, this rotation amount information is also displayed as a symbol corresponding to the lottery result by the winning lottery means 120 on the activated pay line when the three reels 30L to 30R are stopped. In this way, the information is used to control sliding stop of the three reels 30L to 30R. For example, in the present embodiment, in order to stop the three reels 30L to 30R so that the combination of symbols corresponding to the lottery result by the winning lottery means 120 is aligned on the effective line, the winning line L3 is set to the reel rotation position. Information determined as the rotation reference position. That is, if the three reels 30L to 30R are controlled to stop sliding according to the rotation amount information, the rotation amount is set so that the symbol corresponding to the lottery result by the winning lottery means 120 is displayed on the activated winning line. Information is predetermined. Therefore, rotation amount information is determined and stored as the stop control table 135 for all combinations of all lottery results that can be lottery by the combination lottery means 120 and all valid lines that can be set.

  Similarly to the stop information, the rotation amount information is used to perform reel stop control using a fixed rotation reference position as a reference for the reel rotation position. As described above, the rotation reference position is the winning line L3 in the present embodiment, but the winning line L3 is not always validated. For this reason, when the three reels 30L to 30R are stopped, the symbol positioned at the rotation reference position is not necessarily the symbol constituting the symbol combination corresponding to the lottery result by the winning lottery means 120.

  As described above, this amount of rotation only needs to indicate the amount of rotation of the three reels 30L to 30R, and need not be a specific angle or a length along the circumferential direction of the reel. It is preferable to use it.

  In particular, the stop control table 135 is preferably composed of two tables. One table is a table selected when operated in the order of stop switch 44a → stop switch 44b → stop switch 44c. The other table is a table selected when operated in the order of the stop switch 44a → the stop switch 44c → the stop switch 44b. By doing in this way, stop control can be accurately performed according to the order in which the stop switch is operated.

<Valid / Invalid Selection Unit 136>
The valid / invalid selection means 136 selects one of the valid process and invalid process.
The valid process is a process for validating the stop signal generated from the stop switches 44a to 44c and permitting the stop control by the reel stop control means 134. That is, when a stop signal is issued from the stop switches 44a to 44c, the effect that the stop signal is issued is recognized, and the originally scheduled operation is permitted when the stop signal is issued. Note that the effective process only performs the process of permitting the stop control, and the stop control is not always executed as soon as the effective process is performed.

  As described above, the left reel 30L corresponds to the left stop switch 44a. When the stop switch 44a is operated by the player, a stop signal is issued from the stop switch 44a to the main control means 100. The middle reel 30C corresponds to the central stop switch 44b. When the stop switch 44b is operated by the player, a stop signal is issued from the stop switch 44b to the main control means 100. The right reel 30R corresponds to the right stop switch 44c. When the stop switch 44c is operated by the player, a stop signal is issued from the stop switch 44c to the main control means 100.

  When valid processing is performed, processing is performed as follows. When the stop switch 44a is operated by the player and a stop signal is issued from the stop switch 44a, it is validated that the stop signal has been issued and the stop control of the rotating left reel 30L is performed. When the stop switch 44b is operated by the player and a stop signal is issued from the stop switch 44b, the stop signal is issued and the stop control of the rotating middle reel 30C is performed. When the stop switch 44c is operated by the player and a stop signal is issued from the stop switch 44c, it is validated that the stop signal has been issued and the stop control of the rotating right reel 30R is performed.

  On the other hand, the invalidation process is a process for maintaining the rotation control by the reel rotation control means 132 by invalidating the stop signals issued from the stop switches 44a to 44c. That is, even if a stop signal is issued from the stop switches 44a to 44c, the effect that the stop signal is issued is not recognized, and even if it is detected that the stop signal is issued, the fact that the stop signal is issued is ignored. When the stop signal is issued, the originally scheduled operation is not permitted. The invalidation process is only a process that does not permit the stop control, and as a result, the rotation control by the reel rotation control means 132 is maintained.

  When the invalidation process is performed, even when the stop switch 44a is operated by the player and a stop signal is issued from the stop switch 44a, the fact that the stop signal is issued is invalidated, Stop control of the left reel 30L is not performed, and rotation control of the currently rotating left reel 30L is maintained. Even when the stop switch 44b is operated by the player and a stop signal is issued from the stop switch 44b, the stop signal is not issued and the stop control of the middle reel 30C is not performed. The rotation control of the currently rotating middle reel 30C is maintained. Similarly, even when the stop switch 44c is operated by the player and a stop signal is issued from the stop switch 44c, the stop control of the right reel 30R is controlled by invalidating the generation of the stop signal. Without the rotation, the rotation control of the currently rotating right reel 30R is maintained.

<Valid / Invalid Stop Control Unit 138>
The valid / invalid stop control means 138 performs the following two operations: a first operation and a second operation.
First, the first operation is an operation performed after the reel rotation control unit 132 starts the rotation control of the three reels 30L to 30R and then satisfies a predetermined condition. For example, the first operation is performed after satisfying the condition that all of the three reels 30L to 30R start to rotate and the rotation speeds of the three reels 30L to 30R become a constant rotation speed.

  In the first operation, the valid / invalid selection means 136 performs valid processing on a predetermined one of the three reels 30L to 30R, for example, the stop switch 44a corresponding to the left reel 30L. Valid / invalid selection means for all three reels 30L to 30R other than the left reel 30L, that is, the stop switch 44b corresponding to the middle reel 30C and the stop switch 44c corresponding to the right reel 30R An invalid process is performed by 136.

  By performing this first operation, when the player operates the stop switch 44a, the left reel 30L can be stopped according to the operation, whereas the player operates the stop switch 44b. However, the middle reel 30C cannot be stopped, and similarly, even if the player operates the stop switch 44c, the right reel 30R cannot be stopped.

  By performing this first operation, among the three stop switches 44a to 44c, the stop switch that can be operated first by the player can be only the stop switch 44a. That is, after all the three reels 30L to 30R start to rotate and the rotational speeds of the three reels 30L to 30R reach a constant rotational speed, the reels that can be stopped first by the player are the three reels. It can be limited to the left reel 30L of 30L-30R.

This first operation corresponds to the processing in step S24 in FIG.
As a premise for performing the first operation, when the rotation control of the three reels 30L to 30R is started, preferably three stop switches immediately before the rotation control of the three reels 30L to 30R is started. It is necessary to invalidate all of 44a to 44c. This process corresponds to the process in step S21 of FIG.

  The second operation is an operation performed when the left reel 30L that can be stopped first by the player is stopped. This second operation performs an effective process on the stop switch 44b corresponding to the middle reel 30C, which is all reels other than the left reel 30L, and at the same time applies to the stop switch 44c corresponding to the right reel 30R. To perform effective processing.

  By performing the second operation, when the player operates the stop switch 44b, the middle reel 30C can be stopped according to the operation, and when the player operates the stop switch 44c, Accordingly, the right reel 30R can be stopped. Therefore, after the left reel 30L that can be stopped first by the player is stopped, the player can operate any stop switch of the stop switch 44b and the stop switch 44c, which corresponds to the operated stop switch. The reel that has been removed can be stopped.

  By performing the first operation and the second operation as described above, after all the three reels 30L to 30R start to rotate and the rotation speeds of the three reels 30L to 30R become a constant rotation speed, The reel that can be stopped first by the player can be limited to the left reel 30L of the three reels 30L to 30R, and the reel that can be stopped second by the player is the middle reel 30C. Both the right reel 30R and the right reel 30R can be made to be selected by the player to stop the middle reel 30C or the right reel 30R.

  By doing in this way, the player operates the stop switch 44a → stop switch 44b → stop switch 44c in this order to stop the reels in the order of the left reel 30L → the middle reel 30C → the right reel 30R, By operating in the order of the stop switch 44a → stop switch 44c → stop switch 44b, it is possible to select either the case of stopping the reels in the order of the left reel 30L → the right reel 30R → the middle reel 30C.

  That is, from the player's point of view, immediately after all the three reels 30L to 30R start to rotate, all the operations of the three stop switches 44a to 44c are prohibited, and all of the three reels 30L to 30R are prohibited. After a while, the operation of the stop switch 44a is permitted. Further, after the player operates the stop switch 44a to stop the left reel 30L, the remaining stop switches 44b and 44c are permitted to be operated.

<Design detecting means 150>
The symbol detection unit 150 detects a symbol that has reached or can reach a certain rotation reference position based on the stop signal issued from the operation unit 500. That is, in response to the player operating the operation unit 500, the reel drive control unit 130 starts stop control of the left reel 30L, the middle reel 30C, or the right reel 30R. The symbol detection means 150 detects a symbol that may stop at a certain rotation reference position when controlling the reels 30L to 30R by detecting the symbol located at the certain rotation reference position described above. That is, it is possible to detect a symbol that has reached or can reach a certain rotation reference position.

  Even if the reel 30L, 30C or 30R is stopped immediately, even if it is immediately braked, it takes a predetermined time to stop, so even if the symbol is located at a certain rotation reference position, the symbol is kept constant. May not be able to stop at the rotation reference position. That is, even in the case of “a symbol reaching a certain rotation reference position”, the reel may not be stopped so that the symbol is located at a certain rotation reference position. In such a case, the reel stop control means 134 described above controls stop of the reels 30L, 30C, or 30R so that “a symbol that can reach a certain rotation reference position” is located at a certain rotation reference position.

  Here, detecting a symbol specifically means obtaining a symbol number of a stop control table (not shown) stored in advance. The stop control table stores a symbol number and stop information for symbols attached to each of the three reels of the left reel 30L, the middle reel 30C, and the right reel 30R. The symbol number is a numerical value indicating the position of the symbol arrangement on the reel, and is a numerical value indicating the position from the reel reference position along the circumferential direction of the reel, with a certain position on the reel as the reel reference position. The stop information is information used to stop the reels 30L to 30R, and the reels 30L to 30L are positioned so as to be positioned at a fixed reference position in the rotation direction of the reels, for example, on the winning line L3. This is information used to stop-control 30R.

  In addition, the symbol detection means 150 detects the type of symbols stopped on the active line for the reels that have already stopped. The symbol “stopped” on this active line means that, in principle, the effective line is located at the approximate center of the symbol, but when the reel stops, the correspondence between the active line and the symbol is played. If it can be made to recognize a person, it will not be restricted to such a positional relationship.

  As will be described later, the rotation angle sensors 83a to 83c generate signals corresponding to the angles at which the reels 30L, 30C, and 30R are rotated. The symbol number can be obtained based on this signal. Furthermore, the symbol detection means 150 stores a symbol correspondence table (not shown) that defines the correspondence between symbol numbers and symbol types corresponding to symbol numbers. By obtaining a symbol number based on the signals generated from the rotation angle sensors 83a to 83c and searching the symbol correspondence table, the type of symbol corresponding to the symbol number can be obtained.

  The symbol detection by the symbol detection means 150 is executed when the reel stop control process in step S15 in FIG. 4 is performed.

<Design display means 400>
The symbol display means 400 includes reels 30L, 30C and 30R. On each of the reels 30L, 30C, and 30R, a predetermined number, for example, 21 symbols are arranged along the rotation direction of the reel.

  The reel 30L includes a motor 86a for rotating the reel 30L and a rotation angle sensor 83a for detecting the rotation angle of the reel 30L. The reel 30C includes a motor 86b for rotationally driving the reel 30C and a rotation angle sensor 83b for detecting the rotation angle of the reel 30C. The reel 30R includes a motor 86c for rotationally driving the reel 30R and a rotation angle sensor 83c for detecting the rotation angle of the reel 30R.

  The rotation angle sensors 83a to 83c emit signals corresponding to the angles at which the reels 30L, 30C, and 30R are rotated. When the reels 30L to 30R are at a predetermined rotational position in the rotation direction, the rotation angle sensors 83a to 83c generate signals corresponding to the angles rotated from the origin. For example, the reels 30L, 30C, and 30R are divided into one rotation, that is, 360 degrees, equally divided into 400 steps. In this case, the rotation angle sensors 83a to 83c emit signals indicating steps from 0 to 399 according to the angles at which the reels 30L, 30C, and 30R are rotated. Specifically, when the reels 30L to 30R are located at the origin, a signal indicating the 0th step is issued, and when the reels 30L to 30R are at a rotational position rotated by 90 degrees from the origin, a signal indicating the 99th step. To emit. In this way, it is possible to obtain how much the reels 30L to 30R are rotated from the origin based on the signals generated from the rotation angle sensors 83a to 83c. The above description is for conceptually explaining the signals emitted from the rotation angle sensors 83a to 83c. In the slot machine 10, the rotation angle sensors 83a to 83r are used to obtain the positions of the reels 30L to 30R. Instead of detecting a signal emitted from 83c, detection is performed in order to obtain a symbol number or a symbol type or to specify a predetermined symbol position, as will be described later.

  As described above, the symbol detection means 150 stores a symbol correspondence table (not shown) that defines the correspondence between symbol numbers and symbol types corresponding to symbol numbers. Here, for example, when 21 symbols are attached to one reel along the circumferential direction, the symbol number is set to a reel reference position with a certain position on the reels 30L to 30R as a reel reference position. The arranged symbol is the symbol in frame 0. The first frame design, the second frame design,... In this order along the circumferential direction with reference to this origin, and the last 21st design as the 20th frame design. The symbol correspondence table stored in the symbol detection means 150 stores the correspondence between this symbol number and the symbol type corresponding to this symbol number. For example, for the left reel 30L, the symbol correspondence table shows that the 0th frame is the symbol “Plum”, the 8th frame is the symbol “Replay”, and the 16th frame is the symbol “Blue cherry”. Remember.

  By adopting such a configuration, it is possible to search the symbol correspondence table based on signals emitted from the rotation angle sensors 83a to 83c and acquire the symbol type. For example, the symbol number of the reel 30L at the position of the winning line L3 is obtained based on the signal generated from the rotation angle sensor 83a, and the type of the symbol positioned at the winning line L3 can be obtained from the symbol number. . By doing in this way, regardless of whether the reels 30L to 30R are rotating or stopped, the types of symbols positioned on the effective lines L1 to L5 and the effective lines L1 to L5 It is possible to identify the types of symbols that can be stopped.

<< Control processing >>
Below, the control performed in the main control means 100 (main control board 32) mentioned above is demonstrated. 4 to 6 are subroutines for executing control processing in the main control means 100. FIG.

  In the following, the slot machine 10 is started in advance, and in the main control unit 100 described above, after starting processing such as initialization of various variables used for control, the slot machine 10 operates normally. It shall be. Moreover, the flowcharts shown in FIGS. 4 to 6 show only one example for executing the control process in the main control unit 100, and are not limited to this process procedure.

<Control in main control means 100>
FIG. 4 is a flowchart showing control in the main control means 100.
First, the number of inserted sheets for starting a game is determined (step S11). This inserted number indicates the number of medals targeted for betting for one game, and is not only the number of medals targeted for betting after being temporarily accumulated as the number of credits described above, It also includes the number of medals that have been inserted through the medal insertion slot 46 and are directly bet.

  Next, it is determined whether or not the start switch 42 has been operated by the player (step S12). When it is determined that the start switch 42 is not operated, the process of step S12 is repeated. On the other hand, when it is determined that the start switch 42 has been operated, the lottery process is executed by the role lottery means 120 (step S13).

  Next, a subroutine shown in FIG. 5 to be described later is called to start rotation control of the three reels 30L, 30C, and 30R (step S14). Next, a subroutine shown in FIG. 6 which will be described later is called, and stop control of the three reels 30L, 30C and 30R is executed (step S15), a winning process is executed (step S16), and this subroutine is finished.

<Reel rotation control processing>
FIG. 5 is a subroutine for reel rotation control processing executed in step S14 of FIG.
First, invalidation processing is performed on the stop switches corresponding to the three reels 30L, 30C, and 30R (step S21). As described above, the left reel 30L corresponds to the left stop switch 44a, the middle reel 30C corresponds to the center stop switch 44b, and the right reel 30R corresponds to the right stop switch 44c. Further, when the stop switches 44a to 44c are operated by the player, a stop signal is issued from each of them.

  The invalidation process in step S21 is a process for maintaining the rotation control by the reel rotation control means 132 by invalidating the stop signal issued from the stop switches 44a to 44c even if a stop signal is issued from the stop switches 44a to 44c. It is. This “maintaining rotation control by disabling the stop signal” means that even if a stop signal is issued from the stop switches 44a to 44c, the stop control of the reel corresponding to the stop switch that issued the stop signal is not permitted. This means that the rotation control is continued as it is. Specifically, when the invalidation process is performed, even if the stop switch 44a is operated by the player and a stop signal is issued from the stop switch 44a, the fact that the stop signal is issued is invalidated. The rotation control of the currently rotating left reel 30L is maintained. Similarly, even when the stop switch 44b is operated by the player and a stop signal is issued from the stop switch 44b, the fact that the stop signal is issued is invalidated, and the currently rotating middle reel 30C Maintain rotation control. Even when the stop switch 44c is operated by the player and a stop signal is issued from the stop switch 44c, the fact that the stop signal has been issued is invalidated, and the rotation control of the currently rotating right reel 30R is performed. To maintain.

  After executing the process of step S21, all the three reels of the left reel 30L, the middle reel 30C, and the right reel 30R are rotationally driven by the reel rotation control means 132 described above (step S22). Specifically, drive signals are supplied to three motors: a motor 86a for rotationally driving the reel 30L, a motor 86b for rotationally driving the reel 30C, and a motor 86c for rotationally driving the reel 30R. By doing.

  Next, it is determined whether or not all of the three reels of the left reel 30L, the middle reel 30C, and the right reel 30R have reached a predetermined rotation speed (step S23). When it is determined that the three reels 30L to 30R have not reached the predetermined rotation speed, the determination process in step S23 is repeated.

  When it is determined that the three reels 30L to 30R have reached a predetermined rotation speed, the stop switch corresponding to the reel 30L is enabled and the stop switch corresponding to the reels 30C and 30R is disabled. Processing is performed (step S24), and this subroutine is terminated.

  This valid process is a process for permitting the stop control by the reel stop control means 134 by validating the stop signal generated from the stop switches 44a to 44c.

  Specifically, if the stop switch 44a is operated by the player and a stop signal is issued from the stop switch 44a due to the effective processing performed on the stop switch 44a, the stop signal is issued. This is made effective and stop control of the rotating left reel 30L is performed. On the other hand, even if the stop switch 44b is operated by the player and a stop signal is issued from the stop switch 44b due to the invalid processing performed on the stop switches 44b and 44c, the stop signal Is disabled and the rotation control of the currently rotating middle reel 30C is maintained. Similarly, even when the stop switch 44c is operated by the player and a stop signal is issued from the stop switch 44c, the fact that the stop signal has been issued is invalidated, and the right reel 30R currently rotating is being rotated. Maintain rotation control.

  Since the invalidation process is performed on the stop switches 44a to 44c in step S21 described above, the process of step S24 is executed after all three reels 30L to 30R start to rotate in the process of step S22. In the meantime, even if any of the stop switches 44a to 44c is operated by the player, the stop signal is invalidated, and none of the reels 30L to 30R can be stopped.

<Reel stop control process>
FIG. 6 is a subroutine for reel stop control processing executed in step S15 of FIG.

  First, it is determined whether or not the operation of the stop switches 44a to 44c by the player is the first operation (step S31). When it is determined that the operation is the first operation, it is determined whether or not the operated stop switch is the stop switch 44a, that is, whether or not the operation is a stop switch corresponding to the left reel 30L (step S32).

  When it is determined that the operated stop switch is the stop switch 44a, the reel stop control means 134 performs stop control of the left reel 30L corresponding to the stop switch 44a (step S33).

  Next, it is determined whether or not the left reel 30L is stopped (step S34). When it is determined that the left reel 30L is not stopped, the process returns to step S33, and the stop control of the left reel 30L is continued.

  On the other hand, when it is determined that the left reel 30L has stopped, a valid process is performed on the stop switches corresponding to the reels 30C and 30R (step S35), and this subroutine is terminated.

  When the stop switch 44b is operated by the player and a stop signal is issued from the stop switch 44b due to the effective process being performed on the stop switches 44b and 44c in the process of step S35 described above, the stop signal Is made effective and stop control of the rotating middle reel 30C is performed. Similarly, when the stop switch 44c is operated by the player and a stop signal is issued from the stop switch 44c, the stop signal is issued and the stop control of the rotating right reel 30R is performed. .

  If it is determined in the determination processing in step S32 described above that the operated stop switch is not the stop switch 44a, this subroutine is immediately terminated.

  Further, when it is determined in the determination process in step S31 described above that the operation of the stop switches 44a to 44c by the player is not the first operation, whether or not the operated stop switch is the stop switch 44b, that is, the middle reel It is determined whether or not a stop switch operation corresponding to 30C is performed (step S36).

  When it is determined that the operated stop switch is the stop switch 44b, the reel stop control means 134 performs stop control of the middle reel 30C corresponding to the stop switch 44b (step S37).

  In the process of step S37, when the operation of the stop switch 44b is the second operation and there are two tables as the stop control table 135, the table selection process is performed and the selected table is referred to. Then, stop control of the middle reel 30C is performed.

  Specifically, a table selected when two tables are operated in the order of stop switches 44a → 44b → 44c, and a table selected when operated in the order of stop switches 44a → 44c → 44b. Is selected, the table operated in the order of the stop switches 44a → 44b → 44c is selected, and the stop control of the middle reel 30C is performed.

  Next, it is determined whether the middle reel 30C has stopped (step S38). When it is determined that the middle reel 30C is not stopped, the process returns to step S37 and the stop control of the middle reel 30C is continued. On the other hand, when it is determined that the middle reel 30C has stopped, this subroutine is terminated.

  If it is determined in the determination processing in step S36 that the operated stop switch is not the stop switch 44b, it is determined whether or not the operated stop switch is the stop switch 44c, that is, the stop switch corresponding to the right reel 30R. It is determined whether or not it is an operation (step S39).

  When it is determined that the operated stop switch is the stop switch 44c, the reel stop control means 134 performs stop control of the right reel 30R corresponding to the stop switch 44c (step S40).

  In the process of step S40, when the operation of the stop switch 44c is the second operation and there are two tables as the stop control table 135, the table selection process is performed to refer to the selected table. To stop the right reel 30R.

  Specifically, a table selected when two tables are operated in the order of stop switches 44a → 44b → 44c, and a table selected when operated in the order of stop switches 44a → 44c → 44b. Is selected, the table operated in the order of the stop switches 44a → 44c → 44b is selected, and the stop control of the right reel 30R is performed.

  Next, it is determined whether or not the right reel 30R is stopped (step S41). When it is determined that the right reel 30R is not stopped, the process returns to step S39 and the stop control of the right reel 30R is continued. On the other hand, when it is determined that the right reel 30R has stopped, this subroutine is terminated.

  In the embodiment described above, the stop switch that can be operated first by the player is only the stop switch 44a. However, the stop switch that can be operated by the player first is only the stop switch 44b or only the stop switch 44c. Also good. In accordance with stop control for stopping the three reels 30L to 30R, it may be determined which stop switch the player can operate first.

  In particular, when there is a single winning symbol, the reel on which the single winning symbol is arranged is preferably a reel that can be stopped first by the player. Here, the single winning symbol is a symbol that is awarded when the symbol is positioned on the effective line regardless of the type of other symbols positioned on the effective line. "Is a single winning symbol. Specifically, when the symbol “cherry” is arranged on the left reel 30L, when the symbol “cherry” of the left reel 30L is stopped and displayed on the active line, the type of symbols of the middle reel 30C and the right reel 30R is concerned. Suppose you win. In this case, the left reel 30L is preferably a reel that can be stopped first by the player. In this way, when the player first stops the reel, it can be determined whether or not the single winning symbol has been won at that time. Therefore, for the reels to be stopped after the second, when the single winning symbol is won, the stop control is performed so that a role other than the single winning symbol does not win, and when the single winning symbol is not won, If the winning combination is won, the stop control is performed so that the winning combination is won, and if no winning combination is selected, the stopping control may be performed so as not to win any winning combination. Can be.

  Furthermore, when there are two tables as the stop control table 135, the table may be selected by a lottery process. When the stop switch is operated for the second time by the player, it may be selected by lottery processing which table is to be selected for stop control. By doing in this way, the symbol finally located on an effective line can be varied according to the order which operates a stop switch. In particular, in this case, lottery is performed when the operation is performed in the order of the stop switch 44a → the stop switch 44b → the stop switch 44c and when the operation is performed in the order of the stop switch 44a → the stop switch 44c → the stop switch 44b. You may determine so that a probability may differ.
