Therefore, by managing the number of symbols that have been rotated since the reel index was detected, by referring to the symbol arrangement table, the position of the symbol that exists mainly in the middle of the display window and the type of the symbol can be determined. It can always be managed.

[Design combination table]
The symbol combination table will be described with reference to FIG. In the present embodiment, when the symbol combination displayed by each reel 120L, 120C, 120R along the winning determination line matches the symbol combination defined by the symbol combination table, it is determined to be a prize, Benefits based on the results of pachislot games such as medal payout, replay operation, and bonus game operation are given to the player.

  The symbol combination table defines a symbol combination, a display combination, and a payout number that are predetermined according to the type of privilege. The display combination is data for identifying a combination of symbols displayed along the winning determination line.

  The display combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. For example, when the symbol “bell” of each reel 120L, 120C, 120R is displayed along the winning determination line, “bell (00000010)” is determined as the display combination.

  Further, when a numerical value of 1 or more is determined as the payout number, medals are paid out. In the present embodiment, when a cherry, bell, or watermelon is determined as a display combination, medals are paid out. The number of payouts is defined according to the number of inserted sheets. Basically, a larger number of paid-out sheets is determined when the number of inserted sheets is small.

  In addition, when replay is determined as the display combination, replaying is performed. When BB is determined as the display combination, the bonus is activated. If the symbol combination displayed along the winning determination line does not match any of the symbol combinations defined by the symbol combination table, it is a so-called “losing”.

[Bonus operating table]
With reference to FIG. 11, the bonus operation time table will be described. The bonus operation time table defines data to be stored in various storage areas provided in the main RAM 63 when the bonus operation is performed.

  The in-operation flag is data for identifying the type of bonus that is activated. In the present embodiment, BB (a combination continuous action device related to a first type special combination) and RB (a first type special combination) are provided as bonus types. The operation of RB is continuously performed while the operation of BB is performed.

  The operation of BB is ended when the medals that have reached the prescribed number are paid out. The operation of the RB is ended when a game that reaches the specified number of times is performed, when there is a winning that reaches the specified number of times, or when the operation of the BB ends. The bonus end number counter, the possible game number counter, and the possible winning number counter are data for managing whether or not the specified number of times or the specified number of times as a trigger end timing of the bonus has been reached.

  More specifically, numerical values defined by the bonus operation time table are stored in the respective counters, and the subtraction is performed through the operation of the bonus. As a result, the operation of the corresponding bonus is completed on condition that the value of each counter is updated to “0”.

[Internal lottery table] / [Internal winning combination determination table]
[Internal lottery table]
The internal lottery table will be described with reference to FIGS. The internal lottery table defines a data pointer and a lottery value according to the winning number. The data pointer is data acquired as a result of lottery performed with reference to the internal lottery table, and is data for designating an internal winning combination defined by an internal winning combination determination table described later. The data pointer is provided with a small role / replay data pointer and a bonus data pointer.

  In the present embodiment, random numbers extracted from a predetermined numerical range “0 to 65535” are sequentially subtracted by lottery values corresponding to each winning number, and whether or not the result of the subtraction is negative ( An internal lottery is performed by determining whether or not a so-called “digit” has occurred.

  Therefore, the larger the numerical value defined as the lottery value, the higher the probability that the data (that is, the data pointer) to which it is assigned will be determined. The winning probability of each winning number can be represented by “the lottery value corresponding to each winning number / the number of all random numbers that may be extracted (65536)”.

  FIG. 12 shows an internal lottery table for a general gaming state. FIG. 13 shows the internal lottery table for RB operation. In the present embodiment, depending on the situation such as whether or not the bonus is activated, the type of internal winning combination and the winning probability that are determined are varied by using different types of internal lottery tables. , The expectation that the player holds is undulating.

[Internal winning combination determination table]
The internal winning combination determination table will be described with reference to FIGS. The internal winning combination determination table defines an internal winning combination in accordance with the data pointer. When the data pointer is determined, the internal winning combination is uniquely acquired.

  The internal winning combination is data for identifying a combination of symbols of each of the reels 120L, 120C, and 120R that is permitted to be displayed along the winning determination line. Like the display combination, the internal winning combination is represented as 1-byte data in which a unique symbol combination is assigned to each bit. When the data pointer is “0”, the content of the internal winning combination is “lost”, which indicates that any display of symbol combinations defined by the symbol combination table described above is not permitted.

  FIG. 14 shows a small winning combination / replay internal winning combination determining table. The small winning combination / replay internal winning combination determination table defines an internal winning combination relating to the payout of medals or an internal winning combination relating to the operation of replay. FIG. 15 shows an internal winning combination determination table for bonus. The bonus internal winning combination determination table defines internal winning combinations related to the operation of the bonus.

  Next, the main CPU 61 performs a medal acceptance / start check process which will be described later with reference to FIG. 20 (S3). In this process, input checks of the medal sensor 31 and the start switch 110 are performed.

  Next, the main CPU 61 extracts a random value and stores it in a random value storage area provided in the main RAM 63 (S4). Next, the main CPU 61 performs an internal lottery process which will be described later with reference to FIG. 19 (S5). In this process, the internal winning combination is determined by lottery based on a random value. Next, the main CPU 61 transmits a start command to the sub control circuit 80 (S6). The start command includes a parameter for specifying an internal winning combination.

  Next, the main CPU 61 requests the start of rotation of all reels 120L, 120C, 120R (S7). When the start of rotation of all reels 120L, 120C, and 120R is requested, the stepping motors 71L, 71C, and 71R are driven by an interrupt process (FIG. 23 described later) executed at a constant cycle (1.1173 msec). Controlled, rotation of each reel 120L, 120C, 120R is started.

  Next, the main CPU 61 performs a reel stop control process which will be described later with reference to FIG. 20 (S8). In this process, the input of the stop switch 112S is checked, and the rotation of the reel is stopped based on the timing when the stop buttons 112L, 112C, and 112R are pressed and the internal winning combination. Also, the input of the strike switch 301S is checked, and the rotation of the corresponding reel is stopped based on the timing at which the strike button 301 is hit and the internal winning combination.

  Next, the main CPU 61 searches for a combination of symbols displayed along the winning determination lines 126a to 126e, and determines a payout number or the like based on the result (S9). As a result of the search, when the symbol combination displayed along the winning determination lines 126a to 126e matches the symbol combination defined by the symbol combination table, the corresponding display combination and the number of payouts are determined. Next, the main CPU 61 transmits a display command to the sub control circuit 80 (S10). The display command includes parameters that specify the display combination, the number of payouts, and the like.

  Next, the main CPU 61 performs medal payout processing (S11). Based on the determined payout number, the hopper 150 is driven and the credit number is updated. Next, the main CPU 61 updates the bonus end number counter based on the payout number (S12). The numerical value determined as the payout number is subtracted from the bonus end number counter.

  Next, the main CPU 61 determines whether or not the bonus operating flag is on (S13). When determining that the bonus operating flag is on, the main CPU performs a bonus end check process described later with reference to FIG. 22 (S14). It is checked whether or not to end the bonus operation with reference to various counters for managing the bonus end timing.

  The main CPU 61 performs a bonus operation check process which will be described later with reference to FIG. 21 after S14 or when it is determined in S13 that the bonus operating flag is not on (S15). It is checked whether or not the bonus operation starts. When this process ends, the process proceeds to S2.

[Medal reception / start check processing]
Next, with reference to FIG. 20, the medal acceptance / start check process will be described. First, the main CPU 61 determines whether or not the automatic insertion counter is 0 (S31). When it is determined that the automatic insertion counter is 0, the medal passage permission is performed (S32). The solenoid of the selector 31 is driven, and the passage of medals in the selector 31 is prompted.

  When determining that the automatic insertion counter is not 0, the main CPU 61 copies the automatic insertion counter to the insertion number counter (S33). Next, the main CPU 61 clears the automatic insertion counter (S34). S33 and S34 are processes for replaying.

  After S32 or S34, the main CPU 61 sets 3 as the maximum value of the insertion number counter (S35). Next, the main CPU 61 determines whether or not the bonus operating flag is on (S36). When determining that the bonus operating flag is on, the main CPU 61 changes the maximum value of the insertion number counter (S37). For example, the maximum value is changed to 2.

  The main CPU 61 determines whether or not the passage of medals has been detected after S37 or when it is determined in S36 that the bonus operating flag is not on (S38). When determining that the passage of medals has been detected, the main CPU 61 determines whether or not the inserted number counter has reached the maximum value (S39). When determining that the insertion number counter has not reached the maximum value, the main CPU 61 adds 1 to the insertion number counter (S40). Next, the main CPU 61 stores 5 in the valid line counter (S41). Next, the main CPU 61 transmits a medal insertion command to the sub control circuit (S42). The medal insertion command includes a parameter for specifying the number of inserted coins.

  When the main CPU 61 determines in S39 that the inserted number counter is the maximum value, the main CPU 61 adds 1 to the credit counter (S43). The main CPU 61 checks the bet switch 132S after S43, after S42, or when it is determined that the passage of medals is not detected in S38 (S44). A numerical value corresponding to the bet button 132 is added to the inserted number counter while being subtracted from the credit counter.

  Next, the main CPU 61 determines whether or not the insertion number counter has reached the maximum value (S45). When it is determined that the insertion number counter has not reached the maximum value, the process proceeds to S38, whereas when it is determined that the insertion number counter has reached the maximum value, it is determined whether or not the start switch is on (S46). .

  When determining that the start switch is not on, the main CPU 61 proceeds to S38, whereas when determining that the start switch is on, the main CPU 61 prohibits medal passage (S47). The selector solenoid is not driven, and medals are expelled. When this process ends, the main CPU 61 ends the medal acceptance / start check process.

[Internal lottery processing]
Next, an internal lottery process will be described with reference to FIG. First, the main CPU 61 as a winning combination determining means determines an internal lottery table and the number of lotteries (S71). The operating flag storage area is referred to, and the internal lottery table and the number of lotteries are determined according to whether or not the bonus is activated. The number of lotteries indicates the number of times that a lottery value is subtracted and a determination is made as to whether a digit has occurred for each winning number defined by the internal lottery table.

  Next, the main CPU 61 obtains a random value stored in the random value storage area and sets it as a random number for determination (S72). Next, the main CPU 61 sets 1 as the initial value of the winning number (S73).

  Next, the main CPU 61 refers to the internal lottery table and acquires a lottery value corresponding to the winning number (S74). Next, the main CPU 61 subtracts the lottery value from the determination random number value (S75). Next, the main CPU 61 determines whether or not a digit has been made (S76). When the main CPU 61 determines that the digit is not set, the main CPU 61 subtracts 1 from the number of lotteries and adds 1 to the winning number (S77).

  Next, the main CPU 61 determines whether or not the number of lotteries is 0 (S78). When the main CPU 61 determines that the number of lotteries is not 0, the process proceeds to S64. On the other hand, when the number of lotteries is determined to be 0, the main CPU 61 sets 0 as a small role / replay data pointer and serves as a bonus data pointer. 0 is set (S79).

  When the main CPU 61 determines in S66 that a digit has been made, the main CPU 61 obtains the small role / replay data pointer and the bonus data pointer according to the current winning number (S80). After S70 or S69, the main CPU 61 refers to the small winning combination / replay internal winning combination determination table and acquires the internal winning combination based on the small winning combination / replay data pointer (S81).

  Next, the main CPU 61 stores the acquired internal winning combination in the internal winning combination storing area (S82). Next, the main CPU 61 determines whether or not the data stored in the carryover combination storage area is 0 (S83). When the main CPU 61 determines that the data stored in the carryover combination storage area is 0, the main CPU 61 refers to the bonus internal winning combination determination table and acquires the internal winning combination based on the bonus data pointer (S84). ). Next, the main CPU 61 stores the acquired internal winning combination in the carryover combination storing area (S85).

  After determining that the data stored in the carryover combination storage area is not 0 after S85, the main CPU 61 calculates the logical sum of the carryover combination storage area and the internal winning combination storage area, and the result Is stored in the internal winning combination storing area (S86). That is, the internal winning combination relating to the bonus operation is carried over. When this process ends, the internal lottery process ends.

[Reel stop control process]
Next, the reel stop control process will be described with reference to FIG. First, the main CPU 61 as stop control means determines whether or not an effective stop button 112L, 112C, 112R has been pressed (S101). When the main CPU 61 determines that the effective stop buttons 112L, 112C, and 112R are not pressed, the main CPU 61 stands by until it is pressed.

  When the main CPU 61 determines that the valid stop buttons 112L, 112C, and 112R have been pressed, the main CPU 61 invalidates the operation of the corresponding stop button (S102). The valid and invalid states of the stop buttons 112L, 112C, and 112R are managed in a predetermined storage area provided in the main RAM 63.

  Next, the main CPU 61 sets 5 as the number of checks (S103). In the present embodiment, since the maximum number of sliding pieces is set to “4”, when the stop button 112L, 112C, 112R is pressed, the position of the symbol in the middle stage of the corresponding display window is included, and then 4 Up to the position of the individual symbol is the target of the check. That is, any of the five numerical values “0”, “1”, “2”, “3”, and “4” is determined as the number of sliding frames.

  Next, based on the internal winning combination, the main CPU 61 determines the number of checks including the position of the symbol in the middle of the corresponding display window (hereinafter referred to as stop start position) when the stop button 112L, 112C, 112R is pressed. Among the positions of the symbols within the range, the position of the symbol with the highest priority is searched (S104). In this process, the position of the symbol that can display the combination of symbols permitted to be displayed by the internal winning combination along the winning determination line is determined as the position of the symbol with the highest priority.

  Next, the main CPU 61 determines the number of sliding symbols based on the search result (S105). The number of symbols from the stop start position to the symbol position with the highest priority is determined as the number of sliding symbols. Next, the main CPU 61 proceeds to wait for a scheduled stop position (S106). When a transition is made to waiting for the planned stop position, the driving of the stepping motor is controlled by an interrupt process to be described later, and the corresponding reels 120L, 120C, 120R are waited for the position of the symbol with the highest priority to reach the middle stage of the corresponding display window. The rotation of is stopped.

Therefore, when the player starts the game and the reel 120L rotates, the cooling fan 500 rotates accordingly. In this case, the plurality of reels 120L, 120C, and 120R are each formed in a cylindrical shape having an internal space, and each internal space is configured to communicate with each other through a cylindrical end portion. Due to the rotation of the cooling fan 500 provided in the cylindrical shape, an air flow is generated in the cabinet 20 through the cylindrical shapes of the plurality of reels 120L, 120C, 120R arranged in parallel.

  Thereby, the electronic components etc. which were provided in the inside of the cabinet 20 can be cooled with the flow of air.

  Moreover, since the opening parts 22 and 23 are provided in the cabinet 20, external air can be introduce | transduced from these opening parts 22 and 23, and cooling efficiency can be improved further. Further, the openings 22 and 23 are provided with the filters 24 and 25, so that it is possible to prevent, for example, ball cigarette smoke from entering the cabinet 20.

  Further, between the openings 22 and 23 and the cooling fan 500, the wall 27 that forms an air passage is independent from other spaces, so that the outside air can be more efficiently discharged through the openings 22 and 23. Can be introduced.

  Thus, in the pachislot machine 10 of the present embodiment, the cooling fan 500 is integrally provided on at least one of the reels 120L, 120C, and 120R so that the cooling fan 500 rotates as the reel rotates. As a result, it is not necessary to provide a drive unit dedicated to the cooling fan, and accordingly, the electronic components and the like in the cabinet can be cooled without complicating the configuration. In this case, for example, when a drive motor dedicated to the cooling fan is provided, a heating element called a drive motor is added correspondingly, and there is a demerit that the temperature in the cabinet increases due to the addition of the cooling fan. In this embodiment, since there is no need to provide a dedicated driving means, this disadvantage does not occur.

  In particular, in the pachislot machine 10, the reels 120L, 120C, and 120R rotate in response to the game being executed. The fan 500 always rotates as the reel rotates. That is, the cooling fan 500 attached to the reel rotates in accordance with the situation where the reel is always rotated so that games are frequently executed. The cooling fan 500 can reliably rotate to cool the inside of the cabinet.
