Abstract

<P>PROBLEM TO BE SOLVED: To provide a game machine which prevents a game from getting monotonous during a bonus game, and is interesting. <P>SOLUTION: When a "cherry" and a "single bonus" are internally won during an ordinary game state, a combination of symbols relating to the "single bonus" is preferentially displayed (Step S82). During a bonus game, however, only a combination of symbols relating to the "cherry" is arranged. Consequently, even after a shift to a bonus game, since a meoshi is performed to ensure that a combination of symbols relating to the "cherry" is displayed, the game machine prevents a game from getting monotonous even during the bonus game and becomes interesting. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention relates to a gaming machine.

  Among conventional gaming machines, there is a gaming machine having a special bonus capable of continuously winning a bonus for shifting to a gaming state in which an accessory is determined with a high probability.

In such a gaming machine, even in the case of a special bonus, even if it is a combination of symbols that is not usually a bonus prize, a bonus prize is continuously given, so that the player can enjoy the bonus game. The entertainment of the game is maintained (see, for example, Patent Document 1).
Japanese Patent Application Laid-Open No. 08-098912

  However, in such a conventional gaming machine, the JAC winning combination is won with a high probability during the bonus, so the JAC symbol wins, and the combination of symbols related to the winning winning combination of JAC wins by the stop control. Therefore, the stop operation becomes appropriate, and there is a problem that the interest of the game is impaired.

  The present invention has been made to solve such a conventional problem, and an object thereof is to provide an interesting gaming machine even in a gaming state advantageous to a player.

  The gaming machine of the present invention has a symbol display means (for example, display windows 4L, 4C, 4R, reels 3L, 3C) for displaying a plurality of symbols (for example, symbols drawn on the outer peripheral surface of the reels 3L, 3C, 3R). 3R), a start operation detecting means (for example, a start switch 6S) for detecting a start operation, and the symbol display means displayed on the condition that the start operation is detected by the start operation detecting means. Condition that a symbol change means for changing a plurality of symbols (for example, main control circuit 71, stepping motors 49L, 49C, 49R, step S12 in FIG. 16) and the start operation detection means detect the start operation In addition, random number extraction means (for example, main control circuit 71, sampling circuit 37, processing in step S4 in FIG. 15) for extracting random values and extraction by the random number extraction means. The winning combination determining means (for example, the main winning combination determining unit) for determining the winning combination based on the random number value and the table (for example, the internal lottery table for the BB general gaming state) in which the range of random numbers is defined according to the winning combination The control circuit 71, the internal lottery process of FIG. 19), the stop operation detecting means for detecting the stop operation (for example, the stop buttons 7L, 7C, 7R), the stop operation being detected by the stop operation detecting means, Based on the winning combination determined by the winning combination determining means, stop control means (for example, main control circuit 71, processing of step S13 in FIG. 16) for stopping the variation of the symbol performed by the symbol variation means. And the change of the symbol performed by the symbol changing means is stopped by the stop control means, and the game value (example) according to the combination of the symbols displayed on the symbol display means Game value giving means (for example, main control circuit 71, hopper 40) for giving medals, and game state transition means (for example, main control circuit 71, step of FIG. 22) for changing the game state under a predetermined condition. S112), and the table is relatively advantageous to the first winning combination (for example, cherry) that is relatively advantageous to the player to whom the game value is given by the game value granting means and the player. A second winning combination (for example, a single bonus) that is disadvantageous to the same is defined as the same random number range, and the stop control means determines whether the first winning combination and the second winning combination are determined by the winning combination determining means. Detected by the stop operation detecting means on condition that the game state transition means has been determined and the game state has been shifted to a game state that is relatively advantageous to the player (for example, BB general game state). In accordance with the timing of the stop operation that has been performed, control is performed to preferentially stop the combination of symbols related to the first winning combination.

  With this configuration, the stop control means is shifted to a gaming state that is relatively advantageous to the player by the gaming state transition means, and the first winning combination and the second winning combination are determined by the winning combination determining means. According to the condition, according to the timing of the stop operation detected by the stop operation detecting means, the combination of symbols related to the first winning combination is controlled with priority, so the player shifts to an advantageous gaming state After that, since it will be carried out so that the combination of the symbol which concerns on the 1st winning combination will be displayed, the interest with respect to a game can be increased.

  In the gaming machine according to the present invention, in the gaming machine, a specific symbol combination (for example, “white 7-white 7-white 7”) is displayed on the table by the stop control unit, and the gaming state transition is performed. When the first game state (for example, BB general game state) advantageous to the player is transferred by the means, the first winning combination and the second winning combination are determined by the winning combination determining unit. A predetermined winning combination in which a range of random numbers is shifted to a second gaming state (for example, RB gaming state) that is advantageous to a player capable of continuously operating an accessory by the gaming state transition means. It has a configuration characterized in that it is widely defined in comparison with the range of random numbers to be determined.

  With this configuration, in the first gaming state, the winning combination corresponding to the transition of the second gaming state in which the winning combination can be continuously operated by the winning combination determining means is the first winning combination and the second winning combination. Since this is lower than the probability that the winning combination is determined, the ratio of the winning combination can be suppressed as a method of paying out medals to the player.

  According to the present invention, the stop control means is shifted to a gaming state that is relatively advantageous to the player by the gaming state transition means, and the first winning combination and the second winning combination are determined by the winning combination determining means. On the condition that, according to the timing of the stop operation detected by the stop operation detection means, control is performed to preferentially stop the combination of symbols related to the first winning combination, so that the player has an advantageous gaming state Even after the transition to, the game will be held in such a way that the combination of symbols related to the first winning combination will be displayed, so even in a gaming state advantageous to the player, the game will not be monotonous and interesting. A gaming machine can be provided.

  Speakers 21L and 21R are provided on the left and right above the panel display unit 2a. Between the two speakers 21L and 21R, a payout table panel 23 for displaying a combination of display symbols and a payout number of medals is displayed. Is provided.

  In the present embodiment, one game (unit game) basically starts when the start lever 6 is operated, and ends when all the reels 3L, 3C, 3R are stopped.

  In this embodiment, the reel stop operation (operation of any one of the stop buttons 7L, 7C, and 7R) performed when all the reels are rotating is referred to as “first stop operation”. The stop operation performed after “1 stop operation” is referred to as “second stop operation”, and the stop operation performed after “second stop operation” is referred to as “third stop operation”.

  FIG. 2 shows a symbol arrangement table showing the arrangement of symbol rows in which 21 types of symbols represented on the reels 3L, 3C, and 3R are arranged. Each symbol is assigned a code number of “00” to “20” and stored (stored) in a ROM 32 (FIG. 13) described later.

  In accordance with this symbol arrangement table, a symbol row composed of symbols of “white 7”, “replay”, “cherry”, “bell” and “watermelon” is displayed on each reel 3L, 3C, 3R. ing.

  Next, FIG. 3 shows a symbol combination table, which will be described.

  In the pachislot machine 1, when the player operates the start lever 6, an internal lottery is performed to determine an internal winning combination (for example, “cherry small part”, “replay”, “BB”, etc.). If the reel 3 is stopped by the player's stop operation and the symbol combination corresponding to the internal winning combination is stopped and displayed on the active line 8 designated by the player, the display combination is established.

  Here, among the displayed winning combinations, in particular, a winning combination is a winning combination when the symbol combination corresponding to the internal winning combination is stopped and displayed on the active line. If the symbol combination corresponding to the internal winning combination is stopped and displayed on the active line, it is determined that “winning combination is established”.

  As shown in FIG. 3, the symbol combination “Cherry-ANY-ANY” (ANY may be any symbol) is arranged along the effective line, so that “Cherry's small role” is won and the number of inserted medals is 1. When there are two and two medals, one medal is paid out. When the number of inserted medals is three, eight medals are paid out. In addition, when the number of inserted sheets is 3, that is, when five effective lines are set, if the cherry is displayed on the upper or lower stage of the left display window 4L, it is established on two effective lines. Therefore, 15 medals are paid out (16 when the number is twice that of 8 but 16 is the upper limit).

  Further, by arranging the symbol combination “Bell-Bell-Bell” along the active line, the player wins the “bell bell” and 15 medals are paid out regardless of the number of medals inserted.

  In addition, the combination of symbols “watermelon-watermelon-watermelon” is arranged along the active line, so that the “watermelon small part” is won and three medals are paid out regardless of the number of medals inserted.

  The “cherry small part”, the “bell small part”, and the “watermelon small part” may be collectively referred to as “small part”.

  Further, “replay” is established by arranging the symbol combination “replay-replay-replay” along the active line. When “Replay” is established, the same number of medals as the number of inserted medals are automatically inserted, so that the player can play the next game without consuming the medals. In other words, “replay” is a display role that allows a game to be played without establishing a game value when established.

  In addition, when the symbol combination “white 7-white 7-white 7” is arranged along the active line, “BB” is established and the medal is not paid out, but the game state of the next game is “BB game state”. " The gaming state will be described later.

  Further, when the symbol combination “bell-bell-replay” is arranged along the active line, “SRB (shift regular bonus)” is established, and medals are not paid out, but the game state of the next game is “RB”. "Game state".

  In addition, by arranging the symbol combination “Replay-Replay-Bell” along the active line, “SB (single bonus)” is established, and medals are not paid out, but the game state of the next game is “SB game”. State ".

  In addition, there is a combination of symbols other than the symbol combinations related to “Cherry's small part”, “Bell's small part”, “Watermelon small part”, “Replay”, “BB”, “SRB” and “SB”. When displayed, “losing” is established.

  Here, the gaming state will be described. The gaming state indicates a gaming state during the game or during several games, and includes a basic “general gaming state” and a “BB gaming state” advantageous to the player.

  The “BB gaming state” includes a “RB gaming state” in which medals can be easily obtained and a “BB general gaming state” in which the “RB gaming state” is easily transferred.

  More specifically, the “RB gaming state” is a gaming state in which an internal lottery table that is easy to win a winning combination that can win medals at the time of internal lottery is selected, and is a gaming state that is advantageous to the player. . The “internal lottery table” will be described later.

  Further, the “RB gaming state” has an end condition. In the present embodiment, the maximum number of games that can be performed in one “RB gaming state” (this is referred to as the “number of possible RB games”) is twelve. Further, in this “RB gaming state”, the number of times that a winning combination in which medals are paid out can be established (this is referred to as “RB winning number”) is up to eight times. In other words, this “RB gaming state” ends when the number of games reaches 12 times or the winning combination is reached 8 times.

  The “BB general gaming state” is a gaming state in which an internal lottery table that is easy to win an SRB is selected, and is a gaming state that easily shifts to the “RB gaming state”.

  Also in the “BB gaming state”, an end condition is defined. In the present embodiment, the maximum payout possible number in the “BB gaming state” is “350”. In other words, the “BB gaming state” ends when the payout number reaches “350”.

  The “SB gaming state” is the same as the “RB gaming state” in the internal lottery table selected, but the end conditions are different. In other words, the maximum number of games possible in the “SB gaming state” (“SB playable number of times”) is 1, and the number of times that a winning combination can be established (“SB playable number of times”) is 1 time. It is. That is, this “SB gaming state” is completed in one game.

  Further, as described above, the “general gaming state” is a basic gaming state in which there is no privilege advantageous to the player. Furthermore, in the “general gaming state”, when “BB” (internal winning combination related to the operation of the bonus) is won internally, but the symbol combination “BB” is not displayed on the set active line, The winning “BB” will be carried over to the next game. When “BB” is won internally, “BB” is stored as a “carry-over” until the symbol combination “BB” is displayed on the set active line. While “BB” is stored as “carryover role”, the “carryover state” continues. The state where “BB” is carried over as “carry-over” is also referred to as BB internal winning state (BB carry-over state).

  Further, in the “BB general gaming state”, “SRB” can be stored as “carry-over combination”. The state where “SRB” is carried over as “carry-over” is also referred to as SRB internal winning state (RB carry-over state).

  Next, FIG. 4 shows and explains the internal lottery table determination table. This is used in the internal lottery process to determine the type of the internal lottery table and the number of lotteries based on the gaming state.

  In other words, the internal lottery table determination table defines an internal lottery table to be selected according to the gaming state and the number of lotteries indicating how many lotteries are to be performed using the internal lottery table. Here, the number of lotteries indicates the number of lottery processes (corresponding to a subtraction process) performed using a random number acquired prior to the internal lottery process and a lottery value set for each winning number. Yes. The internal winning combination is determined according to the winning number obtained by the internal lottery process.

  As shown in FIG. 4, in the general gaming state, the internal lottery table for the general gaming state is determined as the internal lottery table, and “5” is determined as the number of lotteries. In the BB general gaming state, the internal lottery table for the BB general gaming state is determined as the internal lottery table, and “4” is determined as the number of lotteries. In the RB gaming state (including the SB gaming state), the internal lottery table for the RB gaming state is determined as the internal lottery table, and “3” is determined as the number of lotteries.

  Next, FIG. 5, FIG. 6, and FIG. FIG. 5 shows an internal lottery table for general gaming state, FIG. 6 shows an internal lottery table for BB general gaming state, and FIG. 7 shows an internal lottery table for RB gaming state. This is used to acquire a lottery value based on the winning number and the number of inserted sheets in the internal lottery process.

  As shown in FIGS. 5, 6, and 7, the internal lottery table shows a winning number and a lottery value according to the number of pieces inserted for each winning number. The lottery value divided by a predetermined value ("65536": the difference between this value and the total value of the lottery values is the ratio of “losing”) is the winning rate of the corresponding internal winning combination. In the present embodiment, three internal lottery tables are used: “general gaming state internal lottery table”, “BB general gaming state internal lottery table”, and “RB gaming state internal lottery table”.

  FIG. 5 shows an internal lottery table for a general gaming state. As described above, the internal lottery table for the general gaming state is used in the general gaming state. Here, a winning number and a lottery value are associated with each inserted number of sheets. Based on this general gaming state internal lottery table, there is a possibility that the winning number is determined to be any one of “1” to “5”, and when it is not within the range of any lottery value, the winning number is “ 0 ".

  FIG. 6 shows an internal lottery table for the BB general gaming state. As described above, the BB general gaming state internal lottery table is used in the BB general gaming state. Based on this BB general gaming state internal lottery table, there is a possibility that the winning number is determined to be any one of “1” to “4”, and when it is not within the range of any lottery value, It becomes “0”.

  FIG. 7 shows an RB gaming state internal lottery table. As described above, the internal lottery table for the RB gaming state is used in the RB gaming state (including the SRB gaming state). Based on the RB gaming state internal lottery table, there is a possibility that the winning number is determined to be any one of “1” to “3”. When the winning number is not within the range of any lottery value, the winning number is “ 0 ".

  Here, the internal lottery table is provided for each set value (setting) provided in a plurality of stages (for example, six stages), but the internal lottery table for each set value is omitted. The set value is basically a value set (selected) by the game store side, and the degree of player's advantage in the game (for example, the winning rate, the internal winning probability of the combination, etc.) varies depending on the set value. It has become. Actually, “1” to “6” are provided as set values. Then, the probability of internally winning a combination such as BB is made different between set values. Further, instead of preparing an internal lottery table corresponding to the gaming state for every set value, the same internal lottery table may be shared among the set values. At this time, it may be shared in the same gaming state, or can be shared in different gaming states. Such setting of the internal lottery table can be easily performed by the internal lottery table determination table described above.

  Next, FIG. 8 shows an internal winning combination determination table, which will be described. The internal winning combination determination table is for determining an internal winning combination in accordance with the winning number obtained by the internal lottery process described above.

  As shown in FIG. 8, when the winning number is “0”, “losing” is determined as the internal winning combination in any gaming state.

  In the general gaming state, when the winning number is “1”, “Cherry” and “SB” are determined as the internal winning combination. In the BB general gaming state and the RB gaming state, “Cherry” is determined as the internal winning combination. As a result, “SB” is not won in the BB general gaming state and the RB gaming state, so that “Cherry” is preferentially determined as an internal winning combination in the BB general gaming state and the RB gaming state. It becomes. When the winning number is “2”, “Bell” is determined as the internal winning combination in any gaming state. When the winning number is “3”, “watermelon” is determined as the internal winning combination in any gaming state.

  In the general gaming state, when the winning number is “4”, “Replay” is determined as the internal winning combination. In the BB general gaming state, “SRB” is determined as the internal winning combination. In the general gaming state, when the winning number is “5”, “BB” is determined as the internal winning combination.

  Next, FIG. 9 shows bonus check data and will be described. As shown in FIG. 9, the bonus check data is “01100000” in 8 bits.

  The bonus check data is used for a logical operation (logical product operation) with the internal winning combination in the internal lottery process, and only bonus data is extracted from the internal winning combination.

  Next, FIG. 10 shows the storage area of the internal winning combination (or display combination) and will be described. This storage area is allocated to a predetermined storage area of the RAM 33. Here, the type (bit 0 to bit 7) of each bit data stored is associated with the value (0 or 1) set as the bit data.

  The internal winning combination storage area is used to store the logical sum of the data stored in the internal winning combination and the carryover combination storing area in the internal lottery process.

  Next, FIG. 11 shows the storage area of the carryover combination and will be described. This storage area is also assigned to a predetermined storage area of the RAM 33.

  The carryover combination storage area is also used in the internal lottery process to store the logical sum of the logical combination of the internal winning combination and bonus check data and the data in the carryover combination storage area.

  Next, FIG. 12 shows a bonus operation time table, which will be described. In the bonus operation time table, various information setting values set when the bonus is established are described.

  As shown in FIG. 12, when the display combination “BB” is established and the BB operation process is activated, the “BB operation flag” is set as the operation flag and “350” is set in the bonus end number counter. To do. When the RB operation process is activated, the “RB operation flag” is set as the operation flag, and “12” is set in the possible game number counter, and “8” is set in the possible game number counter.

  When the SB operation time process is activated, the “SB operation flag” is set as the operation flag, and “1” is set in the possible game number counter and “1” is set in the possible game number counter.

  Next, FIG. 13 shows a main circuit configuration of the pachislot machine 1 and will be described.

  FIG. 13 is based on a main control circuit 71 that controls game processing operations in the pachislot machine 1, peripheral devices (actuators) that are electrically connected to the main control circuit 71, and control signals transmitted from the main control circuit 71. A circuit configuration including a liquid crystal display device 5 and a sub-control circuit 72 for controlling the speakers 21L, 21R and the like is shown.

  The main control circuit 71 includes a microcomputer 30 disposed on a circuit board as a main component, and is added with a circuit for random number sampling. The microcomputer 30 includes a CPU 31 that performs a control operation according to a preset program, and a ROM 32 and a RAM 33 that are storage means.

  Connected to the CPU 31 are a clock pulse generation circuit 34 and a frequency divider 35 for generating a reference clock pulse, and a random number generator 36 and a sampling circuit 37 for generating a random number to be extracted (sampled).

  As a means for random number sampling, random number sampling may be executed in the microcomputer 30, that is, on the operation program of the CPU 31. In that case, the random number generator 36 and the sampling circuit 37 can be omitted, or can be left as a backup for the random number sampling operation.

  In the ROM 32 of the microcomputer 30, a program related to the processing of the CPU 31, an “internal lottery table” used for determination of random sampling performed each time the start lever 6 is operated (start operation), and set when a bonus is established. A “bonus operating table” in which various information setting values are defined, a “stop control table” for determining a reel stop mode according to the operation of the stop button, and various control commands for transmission to the sub-control circuit 72 ( Command, signal) and the like are stored.

  Various information is stored in the RAM 33. For example, the extracted random number value, various flags (for example, BB operating flag, RB operating flag), medal credit number, game state information, and the like are stored.

  Further, the sub control circuit 72 does not input commands, information, or the like to the main control circuit 71, and communication is performed in one direction from the main control circuit 71 to the sub control circuit 72.

  As a main actuator whose operation is controlled by a control signal from the microcomputer 30, a hopper (including a drive unit for payout) 40 that stores medals and pays out a predetermined number of medals according to a command from the hopper drive circuit 41, There are stepping motors 49L, 49C, 49R for rotationally driving the reels 3L, 3C, 3R.

  Further, a motor drive circuit 39 for driving and controlling the stepping motors 49L, 49C and 49R and a hopper drive circuit 41 for driving and controlling the hopper 40 are connected to the output section of the CPU 31. Each of these drive circuits receives a control signal such as a drive command output from the CPU 31 and controls the operation of each actuator. The motor drive circuit 39 rotates the stepping motors 49L, 49C, 49R at an arbitrary speed.

  The main input signal generating means for generating an input signal necessary for the microcomputer 30 to generate a control command includes a start switch 6S, a 1-BET switch 11, a 2-BET switch 12, a maximum BET switch 13, There are a C / P switch 14, a inserted medal sensor 22S, a reel stop signal circuit 46, a reel position detection circuit 50, and a payout completion signal circuit 51, which are also connected to the CPU 31.

  The start switch 6S detects the operation of the start lever 6 and generates a start switch signal. The inserted medal sensor 22 </ b> S detects a medal inserted into the medal slot 22.

  When the inserted medal sensor 22S detects a medal inserted into the medal slot 22, the CPU 31 counts this medal and credits up to 50 medals to the RAM 33. The CPU 31 is credited to the RAM 33. The medals are subtracted by the number corresponding to the operation of the 1-BET switch 11, the 2-BET switch 12, and the maximum BET switch 13, the valid lines 8a to 8e are activated, and the BET lamps 9a, 9b, and 9c are turned on. It has become.

  The reel stop signal circuit 46 generates a stop signal in response to the operation of each stop button 7L, 7C, 7R. The reel position detection circuit 50 receives the pulse signal from the reel rotation sensor and supplies a signal for detecting the position of the symbol on each reel 3L, 3C, 3R to the CPU 31. The payout completion signal circuit 51 generates a signal for detecting completion of the medal payout when the count value of the medal detection unit 40S (the number of medals paid out from the hopper 40) reaches the designated number data.

  The random number generator 36 generates random values belonging to a certain numerical range (0 to 65535), and the sampling circuit 37 samples one random value at an appropriate timing after the start lever 6 is operated. An internal winning combination is determined based on the random number values sampled in this way and the internal lottery table stored in the ROM 32.

  After the rotation of the reels 3L, 3C, 3R is started, the number of drive pulses supplied to each of the stepping motors 49L, 49C, 49R is counted, and the counted value is written in a predetermined area of the RAM 33. From the reels 3L, 3C, 3R, reset pulses are obtained for each rotation, and these pulses are input to the CPU 31 via the reel position detection circuit 50. The count value of the drive pulse counted in the RAM 33 is cleared to “0” by the reset pulse thus obtained. As a result, the RAM 33 stores a count value corresponding to the rotation position within the range of one rotation for each of the reels 3L, 3C, and 3R.

  A symbol table (not shown) is stored in the ROM 32 in order to associate the rotational positions of the reels 3L, 3C, and 3R with the symbols drawn on the reel outer peripheral surface. In this symbol table, the code numbers (corresponding to symbol positions) that are sequentially given for each fixed rotation pitch of each reel 3L, 3C, 3R on the basis of the rotational position where the reset pulse is generated as described above, and each code A symbol code indicating a symbol provided corresponding to each number is associated.

  Furthermore, a symbol combination table is stored in the ROM 32. In the symbol combination table, a symbol combination serving as a display combination, a medal payout number of the display combination, and a display combination determination code representing the display combination are associated with each other. The symbol combination table is referred to when the left reel 3L, the middle reel 3C, and the right reel 3R are stopped and when the display combination is confirmed after all the reels 3L, 3C, and 3R are stopped.

  Based on the lottery process (internal lottery process) based on the random number sampling, the CPU 31 selects the reel stop signal sent from the reel stop signal circuit 46 at the timing when the player operates the stop buttons 7L, 7C, and 7R, and the selected one. Based on the “stop control table”, a signal for controlling the stop of the reels 3L, 3C, 3R is sent to the motor drive circuit 39.

  If it becomes a stop mode indicating winning after the internal winning, the CPU 31 updates the credit counter set in the RAM 33 or issues a payout command signal to the hopper drive circuit 41 according to the mode set by the C / P switch 14. And a predetermined number of medals are paid out from the hopper 40. At this time, the medal detection unit 40S counts the number of medals to be paid out from the hopper 40, and when the count value reaches a designated number, a medal payout completion signal is input to the CPU 31. As a result, the CPU 31 stops driving the hopper 40 via the hopper drive circuit 41 and ends the “medal payout process”.

  Next, the configuration of the sub-control circuit 72 is shown in FIG.

  As shown in FIG. 14, the sub control circuit 72 controls the display of the liquid crystal display device 5 based on a control signal from the main control circuit 71, lamps (BET lamps 9a, 9b, 9c, WIN lamp 17) and LEDs. Lighting control of the (payout display unit 18, credit display unit 19, bonus game information display unit 20) and sound output control from the speakers 21L and 21R are performed.

  The sub control circuit 72 is configured on a circuit board different from the circuit board constituting the main control circuit 71, and includes a sound / lamp control circuit 73 and an image control circuit 80.

  The image control circuit 80 includes a serial port 81 for exchanging signals between the main control circuit 71 and the serial port 77, an image control CPU 82, an image control work RAM 83, an image control program ROM 84, a calendar IC 85, and an image ROM 86. A video RAM 87, an image control IC 88, and a control RAM 89.

  Similarly to the main control circuit 71, the image control circuit 80 includes a clock pulse generation circuit, a frequency divider, a random number generator, and a sampling circuit, and is connected to the image control CPU 82 (not shown). These are configured to execute random number sampling.

  Random number sampling is performed by generating random values belonging to the random number range “0-127”, “0-255”, and sampling one random value. The random number sampling can also be performed by the image control CPU 82.

  The image control CPU 82 includes a computer that controls the entire image control circuit 80, and effects data (image information) according to a control program stored in the image control program ROM 84 based on a command transmitted from the main control circuit 71. Various processes such as determination and output (including light emission pattern information and sound information).

  The image control work RAM 83 is configured as a temporary storage unit when the image control CPU 82 executes the image control program stored in the image control program ROM 84.

  The image control program ROM 84 stores an image control program related to display on the liquid crystal display device 5 and various selection tables. The image control program ROM 84 also stores an effect determination table and an effect data determination table.

  The calendar IC 85 stores time information, and the calendar IC 85 and the image control work RAM 83 are backup targets for holding data even when the power is turned off. That is, even when the power supplied to the image control CPU 82 is shut off, the power is continuously supplied, and the stored information and the like are prevented from being erased.

  The image ROM 86 stores image data, dot data, and the like for forming an image. For example, characters such as people and animals, sprite image data such as symbols, characters, and figures, background data, and the like are stored. Sprite image data is an image to be displayed superimposed on a background image (background surface). The video RAM 87 is configured as a temporary storage unit when the image control IC 88 forms an image.

  The image control IC 88 forms an image corresponding to the contents of the effect determined by the image control CPU 82 and outputs the image to the liquid crystal display device 5. The control RAM 89 is included in the image control IC 88, and the image control IC 88 Various control parameters for forming an image are stored.

  In the image control circuit 80, the image control CPU 82 also controls the production of sounds and lamps. The image control CPU 82 determines the sound / lamp type and output timing based on the determined effect data. Then, the image control CPU 82 transmits a command to the sound / lamp control circuit 73 via the serial port 81 at every predetermined timing. The sound / lamp control circuit 73 mainly outputs only the sound / lamp in response to the command transmitted from the image control circuit 80 (excluding volume adjustment control described later).

  The sound / lamp control circuit 73 includes a serial port 77 connected to the serial port 81 of the image control circuit 80, a sound / lamp control CPU 74, a program ROM 75, a work RAM 76, a sound source IC 78, a power amplifier 79, and a sound source. ROM91.

  The sound / lamp control CPU 74 performs sound / lamp output control in accordance with control signals transmitted from the main control circuit 71 and the image control CPU 82 via the serial ports 81 and 77. The sound / lamp control CPU 74 is connected to a payout display unit 18, a credit display unit 19, a bonus game information display unit 20, BET lamps 9 a, 9 b, 9 c, and a WIN lamp 17. The sound / lamp control CPU 74 transmits an output signal to each of the actuators in response to a command transmitted from the image control circuit 80 at a predetermined timing. Thereby, each actuator emits light in a predetermined manner according to the command.

  The program ROM 75 stores a control program executed by the sound / lamp control CPU 74. The work RAM 76 is temporary storage means when the sound / lamp control CPU 74 executes the control program described above.

  The sound source ROM 91 stores sound source data and the like for generating a sound source. The sound source IC 78 generates a sound source using the sound source stored in the sound source ROM 91 based on the command transmitted from the image control circuit 80 and outputs the sound source to the power amplifier 79. The power amplifier 79 is an amplifier to which speakers 21L and 21R are connected. The power amplifier 79 amplifies the sound source output from the sound source IC 78 and outputs the amplified sound source from the speakers 21L and 21R.

  Further, a volume control unit 92 is connected to the sound / lamp control CPU 74. The volume control unit 92 can be operated by a game clerk or the like, and the volume output from the speakers 21L and 21R is adjusted. The sound / lamp control CPU 74 performs control to adjust the sound output from the speakers 21L and 21R to the input volume based on the input signal transmitted from the volume adjustment unit 92 (volume adjustment control).

  Next, FIG. 15 and FIG. 16 show a main flowchart of control processing by the main control circuit 71 of the pachislot machine 1 and will be described. This flowchart shows a processing procedure executed by the control program stored in the ROM 32 and is executed by the CPU 31.

  First, the CPU 31 performs an initialization process at the start of the game (step S1). Specifically, the storage contents of the RAM 33 are initialized, communication data is initialized, and the like.

  Next, initialization processing for one game end, that is, information in a predetermined storage area of the RAM 33 at the end of the game is erased (step S2). Specifically, the data in the writable area of the RAM 33 used in the previous game is erased, the parameters necessary for the next game are written in the write area of the RAM 33, the start address of the sequence program of the next game is specified, etc. I do.

  Next, the CPU 31 performs medal acceptance / start check processing (step S3). Specifically, information for determining whether or not a replay has been established in the previous game based on the replay operating flag, an input from the inserted medal sensor 22S based on the medal insertion into the medal insertion slot 22, and the BET switch 11, In response to inputs from 12 and 13, the insertion number counter set in the RAM 33 is updated. Here, the replay operating flag is information for identifying whether or not replay is established, and the inserted number counter is information for specifying the inserted number in the next game.

  In addition, the effective line is set according to the value of the insertion number counter. For example, if the inserted number counter is 3, the display combination described later is determined based on the combination of symbols displayed on all the effective lines. Further, based on the operation of the start lever 6 on condition that a medal is inserted (for example, the inserted number counter is “1” or more, or the inserted number counter is the maximum value “3”). The presence of input from the start switch 6S is checked. Details of the medal reception / start check process will be described later.

  Subsequently, the CPU 31 performs a random value extraction process for internal lottery (step S4). In this random number extraction process, one random number value is extracted from the random number value in the range of “0 to 65535” generated by the random number generator 36 via the sampling circuit 37, and the extracted random number value is stored in the random number value in the RAM 33. Store in the storage area.

  Next, the CPU 31 performs a gaming state monitoring process (step S5). In this gaming state monitoring process, information for identifying the gaming state in the current game is set in the RAM 33 based on the BB operating flag, RB operating flag, SB operating flag, or carryover combination information.

  Next, the CPU 31 performs an internal lottery process (step S6). In this internal lottery process, the internal lottery table determination table is referred to and the number of lotteries and the type of the internal lottery table are determined based on the gaming state acquired in the gaming state monitoring process.

  For example, when the gaming state is the general gaming state, “5” is determined as the number of lotteries, and the internal lottery table for the general gaming state is determined as the internal lottery table.

  Next, with reference to this internal gaming state internal lottery table, the current internal winning combination is determined based on the random number value obtained by the random number value extraction process (random number value stored in the random number value storage area of the RAM 33). . Next, if the determined internal winning combination is a bonus, this bonus is set in the carryover combination storage area of the RAM 33 as a carryover combination. Further, the logical sum of the current internal winning combination and the carryover combination determined above is determined as the winning combination.

  For example, if “Bell's small role” is determined as the internal winning combination and “BB” is set as the carryover role, “Bell's small role” and “BB” are determined as the winning combinations. That is, the internal winning combination and the carryover combination are information relating to the determination of the display mode of the symbols when the reels are stopped, and these are included and are referred to as “winning combination”. Details of the internal lottery process will also be described later.

  Next, the CPU 31 transmits a “start command” to the sub control circuit 72 (step S8). The “start command” includes internal winning combination, game state information, and the like.

  Subsequently, it is determined whether or not a predetermined time (for example, “4.1 seconds”) has elapsed since the start of the previous game (step S9). If the determination result is “YES”, the game monitoring timer is set. The process proceeds to the set process (step S11), and if “NO”, the process proceeds to the waiting time digestion process (step S10).

  In the waiting time digestion process (step S10), the game start waiting time is digested (wait) without performing the subsequent processes until the predetermined time has elapsed since the previous game started. Specifically, a process of invalidating the input based on the player's operation to start the game is performed until “4.1 seconds” have elapsed since the previous game started.

  Next, in the game monitoring timer setting process (step S11), the game monitoring timer is set. Specifically, an intergame monitoring timer and an automatic stop timer are set. The inter-game monitoring timer is a timer for measuring the time from the start of the game in order to secure the time between the games. The automatic stop timer is used for the player's stop buttons 7L, 7C, 7R. This is a timer for automatically stopping the reels 3L, 3C, 3R without depending on the stop operation.

  Subsequently, the CPU 31 requests the motor drive circuit 39 to start rotation of all reels (reels 3L, 3C, 3R) (step S12), and the motor drive circuit 39 sets all the reels (reels 3L, 3C, 3R). ).

  Next, a reel stop control process is performed (step S13). Specifically, when any of the stop buttons 7L, 7C, and 7R is operated, the reels 3L, 3C, and 3R corresponding to the stop buttons 7L, 7C, and 7R that have been stopped are stopped based on the stop table. . At this time, a “reel stop command” is transmitted to the sub-control circuit 72. The “reel stop command” includes stop reel, stop position information, and the like. Details of the reel stop control process will also be described later.

  When all the stop buttons 7L, 7C, and 7R are operated and all the reels 3L, 3C, and 3R are stopped, the display combination and the number of payouts are determined based on the symbol combination table (step S14). In this process, the display combination (the combination in which the winning combination is established) is identified based on the stop mode of the symbols of the display windows 4L, 4C, 4R, and the display combination flag is set. Specifically, the display combination and the payout number are identified based on the code number of the symbols arranged along the active line, the symbol combination table, and the number of inserted symbols.

  Next, a display combination command is transmitted to the sub control circuit 72 (step S15). The “display combination command” includes information on a display combination flag for specifying a display combination, information on the number of payouts, and the like.

  Next, a medal payout process is performed (step S16). In this medal payout process, in the credit mode, the credit counter set in the RAM 33 is updated based on the payout number information. The value of the credit counter in the credit display unit 19 is displayed based on the update of the credit counter. In the payout mode, the hopper 40 is driven and controlled by the hopper drive circuit 41 to pay out medals based on the payout number information. Further, if the display combination is replay, the CPU 31 turns on the replay operating flag. Further, the CPU 31 updates the number of acquired medals. Thereafter, the CPU 31 transmits a payout end command to the sub control circuit 72. This payout end command includes information indicating that the payout of medals has been completed.

  Next, the CPU 31 updates the value of the bonus end number counter based on the payout number (step S17). Here, if the value of the bonus end number counter is “1” or more, the value of the counter is subtracted according to the number of medals paid out.

  Next, the CPU 31 refers to a predetermined storage area of the RAM 33 and confirms the BB operating flag, the RB operating flag, and the SB operating flag (step S18), and the BB operating flag, RB operating flag or SB If the operating flag is “ON”, a bonus end check process is performed (step S19). The bonus end check process will be described later.

  When the BB operating flag, the RB operating flag, and the SB operating flag are all “off” (determined in step S18), or after the bonus end check process (step S19) is completed, a bonus operation check process is performed (step S20). ). The bonus operation check process will also be described later.

  When the bonus operation check process (step S20) ends, the process returns to the one-game end initialization process (step S2 in FIG. 15).

  Next, FIGS. 17 and 18 show a flowchart of medal acceptance / start check processing, which will be described. 17 and 18 show details of the medal acceptance / start check process (step S3 in FIG. 15) of the main control circuit 71.

  First, in the medal acceptance / start check process, “40000” is set in the demonstration timer (step S31).

  Next, it is determined whether or not the medal acceptance is permitted (step S32). If the medal reception is not permitted, the process proceeds to the insertion number counter determination process (step S41). If the medal acceptance is permitted, it is determined whether or not the inserted medal switch is “ON” (step S33). If the inserted medal switch is not “ON”, a credit insertion process is performed (step S34), and the process proceeds to a determination process of the inserted number counter (step S41). In this credit insertion process, it is determined whether or not the BET switch is “ON”. If the BET switch is “ON”, the credit of the stored medal is determined according to the type of the BET switch. The credit for the designated BET number is subtracted from the number of sheets, and the insertion number counter is updated.

  If the insertion medal switch is “ON”, “1” is added to the insertion number counter (step S35). In the case of medal insertion prohibition (insertion number counter update prohibition), a credit counter is added instead of the insertion number counter.

  Subsequently, a bet command transmission process is performed for the sub-control circuit 72 (step S36). Then, the bet lamp is turned on and “1” is stored in the active line counter (step S37).

  Next, it is determined whether the RB operating flag or the SB operating flag is “ON” (step S38). If the RB operating flag and the SB operating flag are not “ON”, it is determined whether the inserted number is “3” (step S39a). If the inserted number is not “3”, the process proceeds to a determination process of the inserted number counter (step S41). If the inserted number is “3”, the inserted number counter update prohibition process is performed (step S40).

  If the RB operating flag or the SB operating flag is “ON” in the RB operating flag / SB operating flag check process (step S38), it is determined whether or not the number of inserted sheets is “1”. (Step S39b). If the inserted number is “1”, the process returns to the medal acceptance permission determination process (step S32). If the inserted number is not “1”, it is determined whether or not the inserted number is “2” (step S39c). If the inserted number is not “2”, the process proceeds to a determination process of the inserted number counter (step S41). If the input number is “2”, the input number counter update prohibition process is performed (step S40).

  Next, in the insertion number counter determination process, it is determined whether or not the insertion number counter is “1” or more (step S41). If the input number counter is “1” or more, the process proceeds to start switch determination processing (step S46). If the inserted number counter is not "1" or more, that is, if the inserted number counter is "0" and no medal is inserted, it is determined whether or not the demonstration timer is "0" (step S42). If the demonstration timer is not “0”, the process returns to the medal acceptance permission determination process (step S32). If the demonstration timer is “0”, it is determined whether or not the bet lamp is turned off (step S43). If the bet lamp is turned off, the process returns to the medal acceptance permission determination process (step S32). . If the bet lamp is not turned off, the bet lamp is turned off (step S44), a demo command is transmitted to the sub-control circuit 72 (step S45), and the process returns to the medal acceptance permission determination process (step S32).

  Further, as described above, when the insertion number counter is “1” or more in the determination process of the insertion number counter (step S41), it is determined whether or not the start switch is “ON” (step S46). If the start switch is not “ON”, the process returns to the medal acceptance permission determination process (step S32) and the above process is repeated. If the start switch is “ON”, a medal acceptance prohibition process is performed (step S47). Specifically, even if a medal is inserted from the medal insertion slot 22, the medal inserted from the medal return slot is spit out so that the medal cannot be accepted.

  Next, FIG. 19 shows a flowchart of the internal lottery process, which will be described. FIG. 19 shows the details of the internal lottery process (step S6 in FIG. 15) of the main control circuit 71.

  First, the CPU 31 refers to the internal lottery table determination table (see FIG. 4), determines the type of the internal lottery table and the number of lotteries based on the gaming state (step S51), and determines the determined lottery number in the register of the CPU 31. Set to the counter.

  Next, it is determined whether or not the carryover combination storage area is “0” (step S52). With this determination, if the carryover combination storage area is not “0”, that is, if there is a carryover combination, “1” is subtracted from the number of lotteries (step S53). Here, when a carryover combination is generated in the general gaming state, the number of lotteries is changed from “5” to “4”. When a carryover combination is generated in the BB general gaming state, the number of lotteries is “4”. Is changed to "3".

  Next, a winning number is set based on the number of lotteries (step S54). For example, in the general gaming state, when the number of lotteries is “4”, “4” is set as the winning number.

  Next, with reference to the internal lottery table, a lottery value is acquired based on the winning number and the number of inserted sheets (step S55). For example, when the winning number is “1” in the general gaming state, a lottery value “1” is obtained if the inserted number is 1, a lottery value “4” if the inserted number is 2, and a lottery value “36000” if the inserted number is 3. "Get.

  Next, the CPU 31 subtracts the acquired lottery value from the stored random number value (step S56). The subtracted value is held again as a random value, and each lottery value is subtracted from this value after the second time.

  Next, it is determined whether or not a digit is obtained by this subtraction, that is, whether or not the subtraction result is a negative value (step S57).

  If no digit is obtained by subtraction, “1” is subtracted from the number of lotteries (step S59), and it is determined whether or not the number of lotteries has become “0” (step S60).

  If the number of lotteries is not “0”, the process returns to step S54 and the processes in steps S54 to S60 are repeated.

  If it is determined in step S60 that the number of lotteries is “0” or it is determined in step S57 that a digit has been determined, an internal winning combination determination process is performed (step S61). If it is determined in step S60 that the number of lotteries is “0”, the winning number is “0”. In this internal winning combination determination process, the internal winning combination is determined based on the gaming state and the winning number with reference to the internal winning combination determination table. For example, when the winning number is “1” in the general gaming state, “Cherry” and “SB” are determined as the internal winning combination.

  Next, a logical product of the internal winning combination and bonus check data is calculated, and a logical sum with the carryover combination storage area is stored in the carryover combination storage area (step S62).

  In other words, it is effective as a carryover combination only when the current internal winning combination is a bonus (“BB” or “SRB”), and when the other small combination is an internal winning combination, it is already stored as a carryover combination. Only those that are present (bonus) are carried over as carryovers.

  Next, the logical sum of the internal winning combination and the carryover combination storing area is stored in the internal winning combination storing area (step S63).

  That is, in the previous unit game, a bonus (“BB” or “SRB”) is determined as a winning combination and carried over as a carryover combination, and a small role other than these bonuses is determined as a winning combination in this unit game. In this case, a winning flag for both a bonus and a small role as a carryover combination is set.

  Next, FIG. 20 shows a flowchart of the reel stop control process, which will be described. FIG. 20 shows details of the reel stop control process (step S13 in FIG. 16) of the main control circuit 71.

  First, the CPU 31 determines whether any one of the stop buttons 7L, 7C, 7R has been operated effectively (step S81). Specifically, it is determined whether or not a stop signal is output from the reel stop signal circuit 46 based on the operation of the stop buttons 7L, 7C, and 7R. When this determination is “YES”, the process proceeds to step S82, and when it is “NO”, the process returns to step S81.

  Next, the number of sliding symbols is determined based on the internal winning combination (step S82). Here, when “Cherry” and “SB” are determined as the internal winning combination during the general gaming state, the number of sliding symbols is determined so that “SB” is preferentially displayed. Subsequently, a planned stop position is determined based on the determined number of sliding symbols and the current symbol position (step S83).

  Next, the CPU 31 transmits a reel stop command to the sub control circuit 72 (step S84). This reel stop command includes a reel stop identifier and a reel rotation identifier. The reel stop identifier is information related to a reel whose rotation is stopped by any stop operation of the stop buttons 7L, 7C, and 7R. The reel rotation identifier is information indicating the reel state ("rotating" or "stopping"), and is set as "1" during rotation and "0" during stop.

  Next, the CPU 31 determines whether or not there is a rotating reel (whether all reels have stopped) (step S85). If this determination is “YES”, the process returns to step S81, and if “NO”, the reel stop control process is terminated.

  Next, FIG. 21 shows a flowchart of the bonus end check process, which will be described. FIG. 21 shows details of the bonus end check process (step S19 in FIG. 16) of the main control circuit 71.

  First, the CPU 31 determines whether or not a winning is established (step S91). If no winning is established, the process proceeds to step S97.

  If a winning is established, it is determined whether or not the bonus end number counter is “0” (step S92). If the bonus end number counter is not “0”, the process proceeds to step S95.

  If the bonus end number counter is “0”, processing at the end of RB is performed (step S93). Specifically, the RB operation flag is set to “off”, and the values of the game possible number counter and the winning possible number counter are cleared.

  Subsequently, BB end time processing is performed (step S94). Specifically, the BB operating flag is set to “off”.

  When the process at the end of the BB ends, the bonus end check process ends.

  If the value of the bonus end number counter is not “0” (determined in step S92), the value of the winning possible number counter is decremented by “1” (step S95).

  Next, it is determined whether or not the value of the possible winning number counter is “0” (step S96). If the value of the possible winning number counter is “0”, the process proceeds to step S99.

  In this determination, if the value of the possible winning number counter is not “0” or the winning is not established (determined in step S91), the value of the possible game number counter is decremented by “1” (step S97).

  Next, it is determined whether or not the value of the possible game number counter is “0” (step S98). If the value of the possible game number counter is not “0”, the bonus end check process is terminated.

  In this determination, when the value of the game possible number counter is “0” or the value of the winning possible number counter is “0” (determined in step S96), the process at the end of RB or the process at the end of SB (Step S99), and the bonus end check process is ended. In the SB end process, the SB operating flag is set to “off”, and the values of the game possible number counter and the winning possible number counter are cleared.

  Next, FIG. 22 shows a flowchart of the bonus operation check process, which will be described. FIG. 22 shows details of the bonus operation check process (step S20 in FIG. 16) of the main control circuit 71.

  First, the CPU 31 determines whether or not the display combination is “BB”, “SRB”, or “SB (single bonus)” (step S111). If the display combination is not “BB”, “SRB”, or “SB”, the bonus operation check process is terminated.

  When the display combination is “BB”, “SRB”, or “SB”, the BB, RB, or SB activation process is performed based on the bonus activation time table (step S112). Specifically, in the BB operation process, the BB operation flag is set to “ON”, and “350” is set to the bonus end number counter. In the RB operation process, the RB operation flag is set to “ON”, “12” is set in the possible game number counter, and “8” is set in the possible winning number counter. In the SB operation process, the SB operation flag is set to “ON”, “1” is set to the possible game number counter, and “1” is set to the winning number counter.

  Next, only when the display combination is “BB” or “SRB”, the carryover combination storage area is cleared (step S113), and the bonus operation check process is terminated.

  Next, FIG. 23 shows a flowchart of the periodic interrupt process, which will be described. This periodic interrupt processing is periodically performed by the main control circuit 71 every 1.1173 ms.

  First, the CPU 31 temporarily saves data stored in a register used in the internal lottery process (step S6 in FIG. 15) to a predetermined area of the RAM 33 (step S201).

  Next, the CPU 31 performs an input port check process (step S202). In this input port check process, input operations such as detection of a medal insertion by the insertion medal sensor 22S when a medal is inserted from the medal insertion slot 22, and detection of a start operation by the start switch 6S by pressing the start lever 6 are confirmed. .

  Next, the CPU 31 adds “1” to the interrupt counter (step S203). This interrupt counter is used to determine whether to perform reel control or only drive control of lamps and LEDs in the periodic interrupt processing.

  Next, the CPU 31 determines whether or not the value of the interrupt counter is an even number (step S204). If this determination is “YES”, the process proceeds to step S211, and if “NO”, the process proceeds to step S205.

  If the value of the interrupt counter is not an even number, that is, if the value of the interrupt counter is an odd number, the identifier of the left reel 3L is set as a target for rotation control (step S205), and a reel control process is performed (step S206). Next, the identifier of the middle reel 3C is set as a target for rotation control (step S207), and reel control processing is performed (step S208). Next, the identifier of the right reel 3R is set as a target for rotation control (step S209), and reel control processing is performed (step S210).

  Specifically, information indicating the reel to be controlled (one of the left reel 3L, the middle reel 3C, and the right reel 3R) is identified as a reel identifier (for example, left “0”, middle “1”, right “2”). And the motor drive circuit 39 is commanded to control the drive of the reel. Details of the reel control process will be described later.

  In step S211, the CPU 31 performs a lamp / 7SEG driving process for driving lamps and LEDs. In this lamp / 7SEG driving process, the CPU 31 gives a command for displaying, for example, the number of medals stored (credited), the number of paid-out medals, etc. on the credit display unit 19 and the payout display unit 18 in a predetermined RAM 33. Write to storage area. In addition, the CPU 31 stores a command for turning on the BET lamps 9a, 9b, and 9c according to the number of medals bet, a command for turning on the WIN lamp 17 provided on the front surface of the cabinet 2, and the like in a predetermined storage area of the RAM 33. Write to. These commands are transmitted to the sub-control circuit 72.

  Finally, the CPU 31 restores the data stored in the register saved at the beginning of the periodic interrupt process (step S201) from the predetermined area of the RAM 33 (step S212).

  Next, FIG. 24 shows a flowchart of the reel control process, which will be described. FIG. 24 shows details of the reel control processing (step S206, step S208, and step S210 in FIG. 23) in the periodic interrupt processing of the main control circuit 71.

  First, the CPU 31 determines whether or not the reel is controlled to rotate at a constant speed (step S221). If it is not under control, the reel control process is terminated.

  If the reel is being controlled, it is determined whether or not the reel is waiting for a planned stop position (step S222). In this standby position waiting state, constant speed control of the reel is maintained. If this determination is “YES”, the process proceeds to step S223, and if “NO”, the process proceeds to step S225.

  In step S223, the CPU 31 determines whether or not the reel has reached the planned stop position based on the signal from the reel position detection circuit 50 (step S223). If this determination is “YES”, the process proceeds to step S224, and if “NO”, the process proceeds to step S225.

  In step S224, the CPU 31 shifts the reel from the constant speed control state to the deceleration control state (step S224). Thereafter, stop control is performed with all phases of the stepping motors 49L, 49C, 49R of the reel set to “off”.

  In step S225, the CPU 31 performs acceleration control, constant speed control, or deceleration control of the rotation of the reel in accordance with the reel control state (step S225).

  According to the pachislot machine 1 according to the embodiment of the present invention as described above, in the case other than the general gaming state, when “Cherry” and “Single Bonus” are won internally, only the combination of symbols related to “Cherry” Can be aligned. This configuration corresponds to an embodiment of the present invention according to claim 1.
