Description

  The present invention includes a variable display device capable of deriving and displaying a plurality of types of identification information each identifiable in each of a plurality of variable display areas capable of variably displaying, and is derived and displayed in a plurality of variable display areas. The present invention relates to a slot machine in which a winning can be generated according to a combination of identification information.

  A slot machine generally includes a variable display device having a plurality of (usually three) reels on which a plurality of types of symbols as identification information are drawn on the outer periphery, and first, a bet number is determined by a player's BET operation. The reels start to rotate when the start operation is performed with the set number of bets set, and the rotation is stopped by operating a stop button provided corresponding to each reel. When all reels stop rotating, a winning combination is generated when a predetermined winning symbol combination (for example, 7-7-7, hereinafter referred to as a symbol combination) is arranged on the winning line. To do. That is, the game is advanced by the player's operation.

  In addition, in this type of slot machine, when any winning combination is won in the internal lottery, even if the stop operation is not performed at the timing when the constituent symbol of the winning combination is stopped, If it is within the range, the corresponding symbol is drawn and stopped.

  In this way, as a slot machine that performs control to pull in and stop the symbol, either of the roles is won in the internal lottery, and the symbols constituting the internal winning combination are arranged in the drawing range When the player performs a reel stop operation, the number of sliding symbols of the symbols constituting the internal winning combination is determined based on the internal winning combination from the range of 0 to 4 frames, and the number of sliding frames is determined from 2 frames. In the case of 4 frames, the symbols constituting the internal winning combination are drawn while the reels are stopped at the normal stop speed, and when the number of sliding frames is 1 frame, the number of sliding frames is 2 to 4 frames. The number of sliding symbols is recognized by the player by drawing the symbols that make up the internal winning combination while stopping the reel so that the reel stop speed is slower than the case determined in the above range. The Rukoto suggesting prize, has been proposed to increase the player's interest (e.g., see Patent Document 1).

The all-phase excitation is started at a second all-phase start position (a position two steps before the stop position) closer to the stop position than (a position six steps before the stop position).
According to this feature, even when stopping at the same position, when the second stop control is performed, the display is made after the deceleration is started as compared with the case where the first stop control is applied. The time required for the belt to stop becomes longer, and the mode from the start of deceleration to the stop can be diversified. When the second stop control is performed, all-phase excitation is performed in the first stop control. Since the all-phase excitation is started at the second all-phase start position that is closer to the stop position than the first all-phase start position to be started, the deceleration control is started earlier than the first stop control. Even when the second stop control in which the inertial force is weakened, the stop can be stopped at the same stop position as the first stop control.
The deceleration control may be a control for decelerating the rotation speed of the display band by extending the control time to one excitation pattern than at the constant speed rotation, or the excitation pattern at the constant speed rotation. The rotation speed of the display band is reduced by changing the excitation pattern in a different order from the order of change, or by exciting with a pattern in which the excitation phase is excited with a pattern different from the excitation pattern performed at constant speed rotation. It is also possible to perform control.
The deceleration start position at which deceleration control is started is the timing at which control different from the excitation control at the time of constant speed rotation is actually started, and waiting for the start of deceleration with the same control as at constant speed rotation. State does not apply.

The main control unit 41 controls the game, and random numbers in a predetermined range (0 to 65535 in this embodiment). A random number circuit 42 for generating a signal, a pulse oscillator 43 for supplying a clock signal of a constant frequency to the random number circuit 42, and a detection signal input from a switch connected directly to the game control board 40 or via the power supply board 101. Switch detection circuit 44, motor drive circuit 45 that controls the drive of the reel motors 32L, 32C, and 32R, solenoid drive circuit 46 that controls the drive of the flow path switching solenoid 30, various displays and LEDs connected to the game control board 40 LED drive circuit 47 for controlling the driving of the power supply power supplied to the slot machine 1 When a voltage drop is detected, a power interruption detection circuit 48 that outputs a voltage drop signal indicating that to the main control unit 41, when the power is turned on or when an initialization command is not input from the main CPU 41a In addition, a reset circuit 49 for supplying a reset signal to the main CPU 41a and other various devices and circuits are mounted.

  The main CPU 41a has an interrupt function (including an interrupt prohibition function) such as a timekeeping function and a timer interrupt, executes a program (described later) stored in the ROM 41b, and performs processing related to the progress of the game. Each part of the control circuit mounted on the game control board 40 is controlled directly or indirectly. The ROM 41b stores fixed data such as programs executed by the main CPU 41a and various tables. The RAM 41c is used as a work area when the main CPU 41a executes a program. The I / O port 41d inputs / outputs a control signal to / from each circuit connected via a signal input / output terminal included in the main control unit 41.

  Further, the main control unit 41 is supplied with backup power even during a power failure, and the data stored in the RAM 41c is held while the backup power is being supplied.

  The main CPU 41a repeatedly loops the process according to the control state until the detection state of the various switches connected to the game control board 40 is changed as a basic process, and step by step according to the change of the detection state of the various switches. Execute the process to move to. Further, the main CPU 41a has an interrupt function as described above, and can interrupt the basic process by the occurrence of the interrupt and execute the interrupt process. The voltage output from the power interruption detection circuit 48 The power interruption interrupt process (main) is executed in response to the input of the decrease signal, and the timer interrupt process (main) is executed at regular time intervals (about 0.56 ms in this embodiment). In addition, the execution interval of the timer interrupt process (main) is set to a time longer than the sum of the time required to complete the repeated process according to the control state in the basic process and the execution time of the timer interrupt process (main) Therefore, the process that is repeated according to the control state between the current and next timer interrupt processes (main) is completed at least once.

  The main CPU 41a transmits various commands to the effect control board 90 via the I / O port 41d. A command transmitted from the game control board 40 to the effect control board 90 is sent in only one direction, and no command is sent from the effect control board 90 to the game control board 40. A transmission line for commands transmitted from the game control board 40 to the effect control board 90 includes a strobe (INT) signal line, a data transmission line, and a ground line.

  An effect switch 56 is connected to the effect control board 90, and a detection signal of the effect switch 56 is input.

  The effect control board 90 includes a liquid crystal display 51 (see FIG. 1) disposed on the front door 1b of the slot machine 1, an effect LED 52, speakers 53 and 54 (see FIG. 2), the reel LED 55 described above, and the like. Production devices are connected, and these production devices are driven based on control by a later-described sub-control unit 91 mounted on the production control board 90.

  In this embodiment, the sub-control unit 91 mounted on the effect control board 90 controls the output of the effect devices such as the liquid crystal display 51, effect effect LED 52, speakers 53 and 54, and reel LED 55. However, in addition to the sub-control unit 91, an output control unit that directly controls the output of the effect device is mounted on the effect control board 90 or another board, and the sub-control unit 91 is based on a command from the main control unit 41. The output control unit may determine the output pattern of the effect device, and the output control unit may control the output of the effect device based on the output pattern determined by the sub control unit 91. In such a configuration, the sub control unit 91 and the output control may be performed. The output control of the rendering device is performed by both of the units.

  Further, in the present embodiment, the liquid crystal display 51, the effect effect LED 52, the speakers 53 and 54, and the reel LED 55 are exemplified as the effect device, but the effect device is not limited to these, for example, a mechanically driven display. A device or a mechanically driven item may be applied as the effect device.

  Similar to the main control unit 41, the effect control board 90 includes a sub CPU 91a, ROM 91b, RAM 91c, and a microcomputer provided with an I / O port 91d. A display control circuit 92 that performs display control of the liquid crystal display 51 connected to the LED, an LED driving circuit 93 that performs drive control of the effect LED 52 and the reel LED 55, an audio output circuit 94 that controls audio output from the speakers 53 and 54, When the power is turned on or when an initialization command from the sub CPU 91a is not input for a certain period of time, a reset circuit 95 that gives a reset signal to the sub CPU 91a and a detection signal input from the effect switch 56 connected to the effect control board 90 are detected. The switch detection circuit 96 outputs time information including date information and time information. The power supply voltage supplied to the timepiece device 97 and the slot machine 1 is monitored, and when a voltage drop is detected, a power drop detection circuit 98 that outputs a voltage drop signal to that effect to the sub CPU 91a, other circuits, etc. , And the sub CPU 91a receives various commands transmitted from the game control board 40 and performs various controls for performing effects, and directly controls each part of the control circuit mounted on the effect control board 90. To control automatically or indirectly.

  Similar to the main CPU 41a, the sub CPU 91a has an interrupt function (including an interrupt prohibition function). One of the interrupt terminals of the sub control unit 91 is connected to a strobe (INT) signal line that is output when the main control unit 41 transmits a command, among the command transmission lines, and the sub CPU 91a receives the strobe signal. An interrupt is generated based on the input to acquire a command from the main control unit 41 and execute a command reception interrupt process to be stored in the buffer. Further, the sub CPU 91a executes an interrupt process (sub) to be described later by generating an interrupt every time the number of clock inputs reaches a certain number, that is, every certain interval. One of the interrupt terminals of the sub-control unit 91 is connected to the power interruption detection circuit 98, and the sub CPU 91a responds to the input of the voltage drop signal output from the power interruption detection circuit 98. Execute processing (sub). Further, when an unused interrupt occurs in the sub CPU 91a, an unused interrupt process for immediately returning to the original process is executed.

  The sub-control unit 91 is also supplied with backup power at the time of a power failure, and the data stored in the RAM 91c is held while the backup power is supplied.

  In the slot machine 1 of the present embodiment, the medal payout rate changes according to the set value. Specifically, the medal payout rate is changed by using a winning probability corresponding to a set value in an internal lottery described later. The set value is composed of 6 levels of 1 to 6, with 6 being the highest payout rate and the payout rate being lower as the value is decreased in the order of 5, 4, 3, 2, 1. That is, when 6 is set as the set value, the advantage is highest for the player, and as the value decreases in order of 5, 4, 3, 2, 1, the advantage decreases stepwise.

  In order to change the setting value, it is necessary to turn on the power of the slot machine 1 after the setting key switch 37 is turned on. When the setting key switch 37 is turned on and the power is turned on, the setting value read from the RAM 41c is displayed on the setting value display 24 as a display value, and the setting value can be changed by operating the reset / setting switch 38. Transition to the setting change state. When the reset / setting switch 38 is operated in the setting change state, the display value displayed on the setting value display 24 is updated one by one (when further operation is performed from the setting 6, the display returns to the setting 1). . When the start switch 7 is operated, the display value is determined as the set value. Then, when the setting key switch 37 is turned OFF, the determined display value (setting value) is stored in the RAM 41c of the main control unit 41, and the state shifts to a state in which the game can proceed.

  In order to confirm the set value, after the game is over, the setting key switch 37 may be turned on with no bet amount set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 41c is displayed on the setting value display 24, thereby shifting to a setting confirmation state in which the setting value can be confirmed. In the setting confirmation state, the game cannot be progressed, and by turning the setting key switch 37 to the OFF state, the setting confirmation state is ended and the state in which the game can proceed is returned.

  In the slot machine 1 of the present embodiment, when the main CPU 41a detects a voltage drop signal from the power interruption detection circuit 48, a power interruption interrupt process (main) is executed. In the power interruption interrupt processing (main), the register is saved in a stack of a RAM 41c, which will be described later, and data for destructive diagnosis (in this embodiment, 5AH) in which any bit becomes 1, that is, a specific value other than 0 In addition to storing data, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 41c is 0, and the RAM 41c is stored. The RAM parity is a value calculated as an exclusive OR of values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 41c. Therefore, if the RAM parity based on the data stored in all areas of the RAM 41c is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 41c is 1. In this case, the RAM parity adjustment data is 1.

  The main CPU 41a calculates the RAM parity based on the data stored in all areas of the RAM 41c at the time of activation, confirms the value of the destructive diagnosis data, the RAM parity is 0, and the destructive diagnosis The processing state of the main CPU 41a is restored to the state before the power interruption based on the data stored in the RAM 41c on the condition that the value of the data for use is correct, but the RAM parity is not 0 (in the case of 1) or is destroyed. If the value of the diagnostic data is not correct, it is determined that the RAM is abnormal, and the RAM abnormal error code is set in the register to control the RAM abnormal error state so that the progress of the game is disabled. Unlike the other error states, the RAM abnormal error state is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated, and a new set value is set in the setting change state described above. It will not be released until

  In this embodiment, all the data stored in the RAM 41c is held by the backup power source even in the event of a power failure, and when the main CPU 41a determines that the data in the RAM 41c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 41c, only the data necessary for the restoration of the control state in the event of a power failure is backed up among the data stored in the RAM 41c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player For example, it is not necessary to restore the state of all input ports to the state before power interruption.

  In addition, when the sub CPU 91a detects the voltage drop signal from the power interruption detection circuit 98, the sub CPU 91a also executes a power interruption interrupt process (sub). In the power interruption interrupt processing (sub), the register is saved in a stack of a RAM 91c described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity based on 0 becomes 0 and stored in the RAM 91c.

  Then, the sub CPU 91a calculates the RAM parity based on the data stored in all areas of the RAM 91c at the time of activation, and based on the data stored in the RAM 91c on the condition that the RAM parity is 0. The processing state of the sub CPU 91a is restored to the state before the power interruption. If the RAM parity is not 0 (1), it is determined that the RAM is abnormal and the RAM 91c is initialized. In this case, unlike the sub CPU 91a, the execution of the performance is not disabled only by initializing the RAM 91c.

  In this embodiment, all data stored in the RAM 91c is held by the backup power source even during a power failure, and the sub CPU 91a determines that the data in the RAM 91c is normal when the power is turned on. Although the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, only the data necessary for restoration of the control state is backed up in the event of a power failure out of the data stored in the RAM 91c. It may be configured to return to the control state before power interruption based on the backed up data.

  In addition, when returning to the control state before the power interruption when the power is turned on, it is not necessary to return all the control states to the control state before the power interruption, and the minimum control state that does not disadvantage the player It is not necessary to restore the state of the input port or the progress in the middle of the production when it is interrupted. For example, while backing up only data indicating the gaming state such as whether it is in the BB or the normal gaming state, other than the effect corresponding to the gaming state (the effect during the BB during the BB, the normal effect when in the normal gaming state) If a power outage occurs during the execution of a specific production (such as a small role announcement), it will be backed up when the power is turned on instead of resuming the specific production that was being performed at the next power-on. An effect corresponding to the gaming state being played may be executed from the beginning.

  Next, initialization of the RAM 41c of the main control unit 41 will be described. The storage area of the RAM 41c of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a stop phase work, a non-saved work, an unused area, and a stack area.

  The important work is a work in which data that is inconvenient to be initialized at the end of the BB, such as various display devices and LED display data, input / output data of the I / O port 41d, and a game time clock counter, is stored. The general work is a work that stores data that can be initialized at the end of the BB, such as a stop control table, a stop symbol, the number of medals paid out, and the total number of medals paid out in the BB. The special work is a work that stores data to be initialized only before the start of setting, such as data for transmitting a command to the effect control board 90 and various software random numbers. The set value work is a work in which a set value used when performing a lottery in the internal lottery process is stored. After initializing 0 before setting start (before transition to the setting change mode), 1 is stored The set value that is corrected and newly set at the end of the setting (when the setting change mode is ended) is stored. The stop phase work is a work in which data indicating the stop phase of the reel motors 32L, 32C, 32R is stored, and data indicating the stop phase is stored when the reel motors 32L, 32C, 32R are stopped. The Rukoto. The unsaved work is a work that holds the state of various switches, and a value is always set regardless of whether or not the data in the RAM 41c is destroyed at the time of activation. The unused area is an unused area in the storage area of the RAM 41c, and is initialized if any one of a plurality of initialization conditions described later is satisfied. The stack area is an area in which data saved from the register of the main CPU 41a is stored, and the unused stack area is established by any one of a plurality of initialization conditions to be described later, like the unused area. In this case, the used stack area is not initialized because the program continues.

  In this embodiment, the main CPU 41a operates when the setting key switch 37 and the reset / setting switch 38 are both ON, when a RAM error occurs, when starting only when the setting key switch 37 is ON, BB At the end, when the setting key switch 37 and the reset / setting switch 38 are both OFF, when the data in the RAM 41c is not destroyed, the six initialization conditions at the end of one game are satisfied In addition, five types of initialization are performed in different regions to be initialized according to each initialization condition.

  Initialization 0 is performed when the setting key switch 37 and the reset / setting switch 38 are both ON at the time of start-up, and initialization is performed before the transition to the setting change mode or when a RAM error occurs. In initialization 0, all areas (including the unused area and the unused stack area) of the storage area of the RAM 41c other than the used stack area are initialized. Initialization 1 is an initialization performed only when the setting key switch 37 is in an ON state at the time of startup and shifts to the setting change mode. In the initialization 1, the storage area of the RAM 41c is All areas (including the unused area and the unused stack area) other than the in-use stack area and the stop phase work are initialized. Initialization 2 is initialization performed at the end of the BB. In initialization 2, the general work, the unused area, and the unused stack area are initialized in the storage area of the RAM 41c. Initialization 3 is an initialization performed when both the setting key switch 37 and the reset / setting switch 38 are in an OFF state at the time of activation, and the data in the RAM 41c is not destroyed. The stored work, unused area, and unused stack area are initialized. Initialization 4 is initialization performed at the end of one game. In initialization 4, an unused area and an unused stack area in the storage area of the RAM 41c are initialized.

  In this embodiment, initialization 0 and initialization 1 are performed before transition to the setting change mode. However, they may be performed at the end of the setting change mode, that is, after the setting is confirmed. In this case, if the set value work is initialized, the determined set value is lost. Therefore, the set value work is not initialized.

  In the slot machine 1 according to the present embodiment, the prescribed number of bets that can be set according to the gaming state is determined as described above, and the prescribed number of bets that are determined according to the gaming state is set. It becomes possible to start the game on the condition. In the present embodiment, as will be described later, there are a regular bonus (hereinafter referred to as RB) and a normal gaming state as a gaming state, and 3 is defined as the prescribed number of bets in any gaming state. Regardless of the gaming state, when 3 is set as the bet number, the game can be started. In the present embodiment, all of the pay lines L1 to L5 are activated when a specified number of bets corresponding to the gaming state are set.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, a winning combination is obtained when a combination of symbols called “comb” is arranged on the activated winning line (hereinafter simply referred to as a winning line). It becomes. The combination may be a combination of the same symbols or a combination including different symbols. The type of winning combination is determined according to the game state, but it can be roughly divided into a small role with payout of medals and a replay that can start the next game without the need to set the number of bets. There are a game combination and a special combination with a transition of the game state. Below, a small role and a re-playing role are collectively called a general role. In order for winning of each combination determined according to the gaming state to occur, it is necessary to win an internal lottery to be described later and set a winning flag of the combination in the RAM 41c.

  Of these winning flags, the winning flags for the small role and the replaying role are valid only in the game in which the flag is set, and are invalid in the next game. It is valid until the combination of combinations permitted by the flag is complete, and is invalid in a game having the combination of combinations permitted. In other words, once the winning flag for a special role is won, even if the combination of characters allowed by the flag cannot be aligned, the winning flag is not invalidated and is carried over to the next game. It becomes.

  As the role in this slot machine 1, as shown in FIG. 5, a regular bonus as a special role (hereinafter, the regular bonus is RB), a big bonus (1) (2) (hereinafter, a big bonus is BB (1) (2)), watermelon, cherry, and bell are defined as small roles, and replay is defined as a replay role.

  In any game state, when the combination of “Cherry-Bell-ANY” is aligned on any of the winning lines for the left reel in any gaming state, that is, the symbol “Cherry” is derived on any of the winning lines on the left reel. When the “bell” symbol is derived on the winning line where “cherry” is stopped on the left reel of the middle reel, a winning is awarded and two medals are paid out.

  The watermelon is awarded when a combination of “watermelon-watermelon-watermelon” is aligned on any of the winning lines in any gaming state, and 15 medals are paid out.

  The bell is awarded when a combination of “bell-bell-bell” is arranged on any of the winning lines in any gaming state, and 12 medals are paid out.

  Replay is awarded when a combination of “replay-replay-replay” is arranged on the winning line in the normal gaming state. When the replay wins, no medals are paid out, but the next game can be started without setting the number of wagers again, so that three medals corresponding to the number of wagers that are not required to be set in the next game are paid out. Is essentially the same.

  RB is awarded when a combination of “net 7-net 7-black 7” is aligned on any of the winning lines in a gaming state other than RB, and the gaming state shifts to RB. The RB is a gaming state that is advantageous to the player over other gaming states by increasing the winning probability of the small role, especially the bell, and when the 12 games are digested after the RB starts, or a 4-game winning ( When the type of a combination is allowed), it ends either whichever comes first.

  BB (1) is awarded when a combination of “black 7-black 7-black 7” is aligned on any of the winning lines in a gaming state other than RB. BB (2) wins when a combination of “network 7-network 7-network 7” is arranged on any of the winning lines in a gaming state other than RB.

  When BB (1) (2) wins, the gaming state shifts to BB and simultaneously shifts to RB. When RB ends, if BB has not ended, it shifts to RB again and BB ends. Control is repeated until RB. That is, during BB, it is always controlled to RB. The BB ends when the total number of medals paid out to the player in the BB exceeds 480. At the end of the BB, the RB is also ended regardless of whether or not the RB end condition is satisfied.

  Hereinafter, the internal lottery of the present embodiment will be described. In the internal lottery, it is determined whether or not the above winning combination is permitted before the display results of all the reels 2L, 2C, and 2R are derived and displayed (actually, when the start switch 7 is detected). To do. In the internal lottery, first, a random number for internal lottery (an integer from 0 to 65535) is acquired. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, the acquired random number for internal lottery and the number of judgment values for each combination determined according to the gaming state, the number of bets and the set value Is done according to.

  In this embodiment, as shown in FIG. 6, the role is subject to internal lottery depending on whether the gaming state is the normal gaming state or RB (BB), and in the normal gaming state, the special role is different. The target of the internal lottery also varies depending on whether or not it is being carried over (normal: normal gaming state in which special roles are not carried over, winning: normal gaming state in which special roles are carried over).

  If the gaming state is the normal gaming state and the special role is not carried over, RB, BB (1), BB (2), RB + cherry, BB (1) + cherry, BB (2) + cherry, Replay, watermelon, cherry, and bell are sequentially read out as the target combination of the internal lottery.

  If the gaming state is the normal gaming state and the special combination is carried over, the replay, watermelon, cherry, and bell are sequentially read out as the target combinations for the internal lottery.

  If the gaming state is RB (BB), watermelon, cherry, and bell are sequentially read out as the subject combination of the internal lottery.

  In the internal lottery, the number of determination values determined corresponding to the role to be subject to the internal lottery, the current gaming state and the set value are sequentially added to the random number for the internal lottery, and when the result of addition overflows, It is determined that the winning combination has been won. For this reason, a winning combination will be won with a probability (number of determination values / 65536) according to the number of determination values.

  In the internal lottery, when any winning combination is determined, a winning flag corresponding to the winning combination is set in the internal winning flag storing work assigned to the RAM 41c. The internal winning flag storage work consists of a storage area of 2 bytes, of which the upper byte is assigned as the special role storing work for which the special role winning flag is set, and the lower byte is the winning of the general role It is assigned as a general role storage work for which a flag is set. Specifically, when a special combination is won, a special combination winning flag indicating that the special combination is won is set in the special combination storing work, and the winning flag set in the general combination storing work is cleared. When a general combination is won, a winning flag for the general combination indicating that the general combination is won is set in the general combination storing work. If no winning combination is selected, only the general winning combination work is cleared.

  Next, stop control of the reels 2L, 2C, 2R will be described.

  In this embodiment, as a reel stop control method, stop control (hereinafter also referred to as a table method) using a sliding frame number data (data indicating the number of sliding frames according to the stop operation position) registered in the ROM 41b in advance is used. Two methods of stop control based on the search result (hereinafter also referred to as control method) are adopted at each operation timing, and either one is selected depending on the result of the internal lottery and the reel stop status. Stop control is performed by the method of

  In this embodiment, the sliding frame number data when the left reel is first stopped corresponding to all the internal lottery results (first stop operation performed while all reels are still rotating) is previously stored in the ROM 41b. If the left reel is registered as the first stop, regardless of the result of the internal lottery, the stop control is performed by the table method based on the corresponding sliding frame number data, and other than the left reel is set as the first stop. The second stop (any one reel has already stopped and the two reels are rotating, i.e., the second stop operation), the third stop (any two reels stop, When the reel is rotating, that is, in the third stop operation, stop control is performed by the control method.

  The sliding frame number data used when performing stop control by the table method is registered in advance in the ROM 41b, and is selected with reference to the table index stored in the ROM 41b.

  The sliding frame number data is data that can specify the number of sliding frames for each timing when the stop operation is performed. In the present embodiment, a stepping motor that makes one turn at a cycle of 336 steps (0 to 335) is used for the reel motors 32L, 32C, and 32R. That is, when the reel motors 32L, 32C, and 32R are driven in 335 steps, the reels 2L, 2C, and 2R make one round. As shown in FIG. 20, 21 areas (frames) divided into 16 steps (the number of steps in which one symbol moves) per reel are defined. Area numbers 0 to 20 are assigned from the position. On the other hand, the number of symbols arranged on one reel is 21, and symbol numbers 0 to 20 from the reel reference position are assigned to symbols on each reel, so symbols 0 to 20 are assigned to each reel. , Area numbers 0 to 20 are assigned in order. In the sliding frame number data, the sliding frame number by area number is compressed and stored according to a predetermined rule, and the sliding frame number by area number can be acquired by expanding the sliding frame number data. It has become.

  Here, the content of stop control according to the stop control method will be described.

  First, when the CPU 41a performs stop control by the table method, as shown in FIG. 9, when the rotation of the reel is started or when the reel is stopped and the reel that is still rotating is left, If there is a reel that has been stopped as a result of the internal lottery with respect to an unstopped reel, the table index is referenced before the reel stop operation becomes valid, and the stop control table corresponding to the stop position of that reel Select the sliding frame number data.

  First, when the main CPU 41a performs stop control by the table system (in the case of the first left stop), as shown in FIG. 18, before the reel stop operation becomes effective when the reel starts rotating. At this stage, the table index is referred to, and the sliding frame number data corresponding to the result of the internal lottery is selected for the target reel.

  Then, the selected sliding frame number data is expanded and stored in a virtual sliding frame table (see FIG. 20) assigned to the RAM 41c.

  As shown in FIG. 20, in the virtual sliding top table, for each reel, the area corresponding to each area number corresponds to the stop reference position (in this embodiment, the lower symbol area in the perspective window 3). ) (The number of steps from the reel reference position is included in the range of the number of steps of each area number), and the number of sliding frames when the operation of the stop switches 8L, 8C, 8R is detected is stored. The number of sliding symbols developed from the sliding frame number data is stored in correspondence with the corresponding area number of the corresponding reel.

  Thereafter, the stop operation is validated. In this state, when any of the stop switches 8L, 8C, 8R corresponding to the rotating reel is effectively detected, the reel reference at the time when the stop operation is detected. The area number of the stop operation position is identified based on the number of steps from the position, and the number of sliding frames corresponding to the identified area number of the stop operation position is obtained by referring to the virtual sliding frame table of the reel where the stop operation is detected. To do. Based on the acquired number of sliding symbols, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  Specifically, from the number of steps from the reel reference position at the time when the stop operation is detected, the number of steps from the acquired number of sliding frames until the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Do. As a result, an area (stop point in the figure) corresponding to the area number that is the stop position ahead of the number of sliding frames from the area (stop operation point in the figure) corresponding to the area number of the stop operation position in which the stop operation is detected. It stops at the stop reference position (in this embodiment, the lower symbol area of the fluoroscopic window 3).

  Next, when the main CPU 41a performs stop control by the control method (when the other than the left reel is the first stop, the second stop and the third stop), the reel is stopped as shown in FIG. When the reels that are still rotating still remain, the stop operation is performed based on the stop position of the stopped reels as a result of the internal lottery for the unstopped reels before the reel stop operation becomes effective. For each position, a stop position corresponding to the result of the internal lottery (a stop position where the winning combination is aligned on the winning line) is searched.

  Specifically, for each stop operation position, a stop position for each of the 0 to 4 sliding frames is specified, and each of these stop positions is determined for illegal winning (a role not won in the internal lottery) and a stop prohibited position ( In the case of a stop, a determination is made of a stop position where it is not possible to avoid illegal winnings or duplicate winnings on an unstopped reel. If it is an illegal winning or stop prohibiting position, a stop prohibiting position flag is set.

  Then, the stop position according to the number of sliding frames of 0 to 4 is determined according to the combination in the order of determining whether the winning combination is a stop position where the winning combination is aligned on the winning line (especially, in the order of giving the top priority to two frames in cherry) Yes, in this embodiment, the order of 2 → 0 → 1 → 3 → 4 is applied), and when it is determined that the winning combination is a stop position that is aligned on the winning line, Whether or not the stop prohibition position flag is set, and if the stop prohibition position flag is not set, the stop position is acquired, and the number of slip frames that become the acquired stop position is obtained in the virtual slide top table. Stored in the area number of the corresponding stop operation position of the corresponding reel.

  Even if it is determined that the winning combination is a stop position on the winning line, if the stop prohibition position flag is set for the stop position, the next stop position is determined. In addition, if there is no stop position where the winning combination is on the winning line even after determining the stop positions of all the slide frames, the number of slide frames that will be the last determined stop position is indicated in the virtual slide frame table. And the area number of the corresponding stop operation position. In addition, when the stop prohibition position flag is set for the stop position determined last, the number of slip frames that is acquired retroactively to the stop position for which the stop prohibition position flag is not set and becomes the acquired stop position Is stored in the area number of the corresponding stop operation position of the corresponding reel in the virtual sliding top table. In this embodiment, as will be described later, the symbols “bell” and “replay” are arranged at intervals of 4 frames or less on all reels, and the reels are pulled in and stopped within the range of 0 to 4 frames. This makes it possible to make sure that the bells or replays are aligned on the winning line.

  After the number of sliding symbols is stored for all the area numbers of the rotating reels in the virtual sliding frame table, the stop operation is validated, and in this state, among the stop switches 8L, 8C, 8R, the rotating reels When any of the corresponding operations is detected effectively, the area number of the stop operation position is identified based on the number of steps from the reel reference position at the time when the stop operation is detected, and the reel of which the stop operation is detected With reference to the virtual sliding top table, the number of sliding tops corresponding to the area number of the specified stop operation position is acquired. Based on the acquired number of sliding symbols, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

In this embodiment, since the number of sliding frames is always in the range of 0 to 4, it is possible to stop the reel by drawing in a maximum of 4 symbols after detecting the stop operation. In other words, the stop position of the symbol can be designated from a range of a maximum of 5 frames including the stop operation position where the stop operation is detected. In addition, since it is necessary to move one frame to move the reel for one symbol, it is possible to stop the reel by pulling in a maximum of four symbols after detecting the stop operation. The symbol stop position can be designated from a range of up to five symbols including the operation position.

  In the table index, the number of sliding frames that draws the winning combination as much as possible within the range of 4 frames to the address corresponding to the case where one of the roles is won, and draws the winning combination so that there are no winning combinations. The index data that identifies the number of sliding frames specified is stored, and the number of sliding frames for which the number of sliding frames to be pulled in so that none of the roles are aligned is stored in the address corresponding to the case where the winning combination is lost In addition to storing index data for specifying data, the number of sliding frames that draws the winning combination to the maximum in the range of 4 frames is stored in the virtual sliding frame table even when the stop operation is performed by the control method.

  Therefore, if any winning combination is won, regardless of the stop control method, the maximum number of winning combinations will be drawn within the range of 4 frames, and the number of sliding frames that will be pulled in so that there is no winning combination. Is stored in the virtual sliding top table and the reel stop control is performed. On the other hand, if none of the roles is won, the number of sliding tops that do not have any of the roles is stored in the virtual sliding top table and the reel The stop control is performed. As a result, when the stop operation is performed, if the symbols of the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed to align them and stop. The symbol of the winning combination will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  As shown in FIG. 3, the “bell” on the left reel, the “bell” on the middle reel, and the “bell” on the right reel, which constitute the bell, are arranged at intervals of 4 frames each. Regardless of the timing at which the reels are stopped, the “bell-bell-bell” combination is always on the winning line, and the bell wins. In addition, the “replay” for the left reel, “replay” for the middle reel, and “replay” for the right reel, which are part of the replay, are arranged at intervals of 4 frames each. In any case, the combination of “replay-replay-replay” is always on the winning line, and the replay wins.

  On the other hand, while the “bells” of the middle reel that make up the cherry are arranged at intervals of 4 frames or less, the “cherries” of the left reel that make up the cherry are arranged at intervals exceeding 7 frames. When winning the cherry, if the stop operation of the left reel is performed at the timing of the “cherry” pull-in range, the combination of “cherry-bell-ANY” will be aligned with the winning line, and the cherry will win. If the left reel is stopped at a timing outside the “cherry” pull-in range, the cherry will not be won and will be missed.

  In addition, the "watermelon" on the left reel, the "watermelon" on the middle reel, and the "watermelon" on the right reel, which make up the watermelon, are located at intervals of more than 4 frames. If each reel is stopped at the timing of the drawing range, the combination of "watermelon-watermelon-watermelon" will be aligned on the winning line, and the watermelon will win, but even one of the reels will draw "watermelon" If the stop operation is performed at a timing outside the range, the watermelon will not be won and will be lost.

  In addition, there are places where the special symbols are placed at intervals exceeding 4 frames, and even if one of the special roles is won, each reel has a timing that will be within the drawing range of the winning special symbols. If a stop operation is performed, the winning special role will be awarded, but if any one of the reels is stopped at a timing that is outside the drawing range of the winning special component, the special role will not win. I will miss it. Note that even if a special role is missed as described above, it will be carried over to the next game, so if you win a special role once, for example, even if you miss it, you will win by performing a stop operation at an appropriate timing after the next game It becomes possible to make it.

  If the special role is elected while the special role has been carried over from before the previous game, or if the special role and the small role are elected at the same time when the special role is not carried over, the special role and the small role are won simultaneously. When the stop operation is performed, if it is possible to stop all the small roles that have been selected in the drawing range of up to 4 frames on the winning line and stop them, control is performed to stop them together. If you cannot draw a small role that has been won in the drawing range of up to 4 frames on the winning line, you must stop the special role that has been won in the drawing range of up to 4 frames on the winning line. If it is possible, control is performed to stop all of them together, and a winning combination that has not been won will be controlled to be stopped within the 4-frame pull-in range. That is, in such a case, priority is given to the control for aligning the small combination on the winning line over the special combination, and the special combination can be made effective only when the small combination cannot be drawn.

  In this embodiment, when a special role and a small role are simultaneously elected, the control for aligning the small role on the winning line is prioritized over the special role, and the special role is given only when the small role cannot be drawn. However, priority is given to the control of aligning the special role on the winning line over the small role, and it is possible to win the small role only when the special role cannot be drawn. It is good also as a structure.

  The special role and re-playing role are selected when the re-playing role is elected while the special role has been carried over from before the previous game, or when the special role and re-playing role are won at the same time without the special role being carried over. In the case of winning at the same time, when a stop operation is performed, control is performed so that the symbols of the re-gamer are aligned and stopped on the winning line within a drawing range of a maximum of 4 frames. In this case, the symbols constituting the re-playing combination are arranged within 5 symbols for each of the reels 2L, 2C, and 2R, that is, with an interval of 4 frames or less. Therefore, if a special combination and a replaying player are elected at the same time, the replaying game will always be awarded regardless of the operation timing of the stop switches 8L, 8C and 8R by the player. Will be. That is, in such a case, the control for aligning the re-games on the winning line has priority over the special game, and the re-games will always win.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main CPU 41a continues to rotate the reels for which the stop operation has not been detected until the operation of the stop switches 8L, 8C, and 8R is detected. On the condition that the operation of the stop switches 8L, 8C, 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  In this embodiment, control is performed to stop the display result on the corresponding reel on condition that the operation of the stop switches 8L, 8C, and 8R is detected. However, the rotation of the reel is started. When a predetermined automatic stop time has elapsed, even if the reel stop operation is not performed, it is assumed that the stop operation has been performed, and automatic stop control is performed to automatically stop each reel. May be. In this case, since the reels are stopped without the player's operation, it is preferable to derive a display result that does not constitute any combination even if any combination is won.

  Next, commands that the main CPU 41a transmits to the effect control board 90 will be described.

  In this embodiment, the main CPU 41a sends a BET command, a credit command, an internal winning command, a low speed stop command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end command to the effect control board 90. A plurality of types of commands including a game state command, a standby command, a stop command, an error command, a return command, a setting start command, a confirmation start command, a confirmation end command, and an operation detection command.

  These commands are composed of 1-byte type data indicating the type of command and 1-byte extension data indicating the content of the command, and the sub CPU 91a can determine the type of command from the type data.

  The BET command is a command that can specify the number of inserted medals, that is, the number of medals used to set the bet number, and is a state from the end of the game (after setting change) to the start of the game. Sent when a medal is inserted or the MAXBET switch 6 is operated to set the number of bets in a state where is not set. Further, since the BET command is transmitted when the betting number setting operation is performed, it is possible to specify that the betting number setting operation has been performed by receiving the BET command.

  The credit command is a command that can specify the number of medals stored as credits, and is a state from the end of the game (after setting change) to the start of the game, and in a state where a predetermined number of bets is set, Sent when a medal is inserted and credits are added.

  The internal winning command is a command that can specify the winning status of the internal winning flag and the type of the internal winning flag established, and is transmitted when the start switch 7 is operated to start the game. Further, since the internal winning command is transmitted when the start switch 7 is operated, it is possible to specify that the start switch 7 has been operated by receiving the internal winning command.

  The low speed stop command is a command that can specify the result of the low speed stop lottery described later, that is, whether the low speed stop control 1 is executed, the low speed stop control 2 is executed, or the low speed stop control is not executed. Sent after low speed lottery.

  The reel rotation start command is a command for notifying the start of reel rotation, and is transmitted when rotation of the reels 2L, 2C, and 2R is started.

  The reel stop command indicates whether the reel to be stopped is a left reel, a middle reel, or a right reel, the area number of the corresponding reel stop operation position, the area number of the corresponding reel stop position, and normal stop control. Or a low-speed stop control 1 or a low-speed stop control 2, which is a command that can be specified, and is transmitted each time stop control associated with a stop operation of each reel is performed. Since the reel stop command is transmitted when the stop switches 8L, 8C, and 8R are operated, it is possible to specify that the stop switches 8L, 8C, and 8R are operated by receiving the reel stop command. .

  The winning determination command is a command that can specify the presence / absence of winning, the type of winning, and the number of medals to be paid out at the time of winning, and is transmitted after all the reels are stopped and the winning determination is performed.

  The payout start command is a command for notifying the start of payout of medals, and is transmitted when the payout of medals is started by paying out a prize or credit (including medals used for setting the number of bets). The payout end command is a command for notifying the end of payout of medals, and is transmitted when the payout of medals by winning and winning a credit is completed.

  The game state command is a command that can specify the game state of the next game, and is transmitted when the setting change state ends and when the game ends.

  The standby command is a command indicating a transition to the standby state, and after one game is over, a credit (which was used for setting the bet number) is set when the transition to the standby state is made after a predetermined time without setting the bet number. (Including medals) is sent out after the medal payout is completed and the payout end command is sent.

  The stop command is a command indicating the occurrence or release of the stop state, and after the end of the BB, the stop command indicating the occurrence of the stop state is transmitted when the ending effect waiting time has elapsed, and the reset operation is performed. When the stop state is released, a stop command indicating the release of the stop state is transmitted.

  An error command is a command that indicates the occurrence or cancellation of an error condition and the type of error condition. When an error is determined and controlled to an error condition, an error command indicating the occurrence and type of the error condition is sent and reset. When the error state is canceled after the operation is performed, an error command indicating the cancellation of the error state is transmitted.

Release command is a command indicating that the main CPU 41 a is returned to the control state before the power interruption, it is transmitted upon returning to the control state before the power failure at the time of startup of the main CPU 41a.

The setting start command is a command indicating the start of the setting change state, and is transmitted when shifting to the setting change state. Moreover, since with the transition to the setting change state control state of the main CPU 41 a is initialized, it is possible to specify that the control state of the main CPU 41 a is initialized by setting start command.

  The confirmation start command is a command indicating the start of the setting confirmation state, and is transmitted when shifting to the setting confirmation state. The confirmation end command is a command indicating the end of the setting confirmation state, and is transmitted when the setting confirmation state ends.

  The operation detection command is a command indicating the detection state (ON / OFF) of operation switches (MAXBET switch 6, start switch 7, stop switches 8L, 8C, 8R), and is transmitted at regular intervals.

  Among these commands, a setting start command, an error command indicating a RAM abnormality, and a return command are generated at a stage before an interrupt is permitted in the startup process and stored in a specific command transmission buffer assigned to a special work in the RAM 41c. And sent immediately.

  Commands other than a setting start command, an error command indicating a RAM abnormality, a return command, and an operation detection command are generated according to the progress of the game in the game process, and are temporarily stored in a normal command transmission buffer provided in a special work in the RAM 41c. Stored and transmitted in timer interrupt processing (main).

  In this embodiment, a command is generated in the game process and stored in the normal command transmission buffer. When an untransmitted command stored in the command transmission buffer is detected in the command transmission processing in the timer interrupt 2, the untransmitted command stored in the normal command transmission buffer is transmitted.

  In addition, the normal command transmission buffer has an area where a plurality of commands can be stored, so that newly generated commands can be stored without waiting for transmission of unsent commands stored in the normal command transmission buffer. Normally, it can be stored in an empty area of the command transmission buffer. That is, a plurality of commands can be stored in the normal command transmission buffer.

  In addition, when commands are stored in the normal command transmission buffer in the game process, these commands are stored in the order of generation, and in the command transmission process, the commands are transmitted in the order generated and stored in the normal command transmission buffer. It has become. That is, the commands stored in the normal command transmission buffer are transmitted in the order in which they are generated and stored.

  The operation detection command is generated every time the command transmission process is executed five times, stored in the aforementioned specific command transmission buffer, and immediately transmitted. In addition, when the operation detection command transmission time is reached with the unsent command stored in the normal command transmission buffer, priority is given to the transmission of the operation detection command and the normal command transmission buffer stores it. The untransmitted command is transmitted in the next command transmission process, and a plurality of commands are not transmitted in one command transmission process.

  Next, the control of the effect performed by the sub control unit 91 based on a command transmitted from the main CPU 41a to the effect control board 90 will be described.

  The sub CPU 91a executes a command reception interrupt process when a strobe signal indicating the transmission of a command from the main CPU 41a is input. In the command reception interrupt process, the command acquired from the command transmission line is stored in the reception buffer provided in the RAM 91c.

  In the timer interrupt process (sub), the sub CPU 91a determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub CPU 91a is the earliest stage. Based on the received command, the control pattern table stored in the ROM 91b is referred to. Based on the control contents registered in the control pattern table, various effects such as the liquid crystal display 51, the effect LED 52, the speakers 53 and 54, the reel LED 55, etc. Control the output of the device.

  In the control pattern table, the display pattern of the liquid crystal display 51 corresponding to the type of command, the lighting mode of the lighting effect LED 52, the output mode of the speakers 53 and 54, the lighting mode of the reel LED, etc. The control patterns of these effect devices are registered, and when the sub CPU 91a receives the command, the sub CPU 91a, among the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table, With reference to the control pattern corresponding to the type of command received, output control of the rendering device is performed based on the control pattern. Thereby, the production according to the production pattern and the progress of the game is executed.

  If the sub CPU 91a receives a new command during execution of an effect triggered by the reception of a certain command, the sub CPU 91a stops the effect based on the control pattern being executed, and responds to the newly received command. An effect based on the control pattern is executed. In other words, even if the production is not finished to the end, when a new command is received, the production that was being executed is canceled and a new command is canceled unless the received new command is not a command that triggers a new production. An effect based on the command is executed.

  In particular, in this embodiment, when an operation for setting the number of bets is made during the execution of an effect, that is, when the sub CPU 91a receives a BET command indicating that the number of bets has been set, the effect being executed is canceled. It is supposed to be. For this reason, if the player wants to proceed to the next game rather than seeing the production to the end, the production is canceled and the next game can be started. There is no. Further, when a credit or bet amount adjustment operation is performed during the performance, that is, after the sub CPU 91a receives a game state command indicating the end of the game, and before receiving an internal winning command indicating the start of the game. When the payout start command is received, the performance being executed is stopped. Credits and bets are settled when the game is terminated. In such a case, by terminating the performance that is being executed, there is an intention to end the game, but the performance continues unnecessarily. It is designed not to be overwhelmed.

  When the internal winning command is received, the effect pattern is selected at a selection rate corresponding to the result of the internal lottery indicated by the internal winning command, and is set in the RAM 91c. The selection rate of the effect pattern is registered in the effect table stored in the ROM 91b, and when the sub CPU 91a receives the internal winning command, the sub CPU 91a sets the level and the effect setting described later as a result of the internal lottery indicated by the internal winning command. Accordingly, the selection rate registered in the effect table is referred to, one of the effect patterns is selected from the plurality of types of effect patterns according to the selection rate, and the selected effect pattern is set in the RAM 91c as the effect pattern of the game. Even if the same command is received, a different control pattern is selected depending on the effect pattern selected when the internal winning command is received. As a result, different effects may be performed depending on the effect pattern.

  FIG. 7 is a diagram illustrating the configuration of the reel motors 32L, 32C, and 32R. The reel motors 32L, 32C, and 32R are, for example, hybrid type stepping motors, and include a stator 32b and a rotor 32a facing the stator 32b. The rotor 32a has a large number of gear-shaped salient poles (not shown), and permanent magnets magnetized in the same direction as the rotation shaft are incorporated therein.

  The main CPU 41a performs a process of updating the excitation state of each excitation phase φ1 to φ4 in the timer interrupt process (main) described above, and a pulse signal is output from the motor drive circuit 45 accordingly. The reel motors 32L, 32C, 32R receive this pulse signal, and the excitation phases φ1 to φ4 of the stator 32b are excited according to a predetermined procedure, so that each time one pulse is received, a predetermined angle (1 step = approx. The rotor 32a is rotated by 1.07 (360/336) degrees.

  FIG. 8 is a diagram showing a step rate at the time of reel acceleration at the start of the reel motors 32L, 32C, 32R, and FIG. 9 is a timing chart at that time.

  One step is a unit to which one excitation pattern is applied. During constant speed rotation, the rotor 32a rotates by the predetermined angle (about 1.07 (360/336) degrees) described above for each step. Therefore, in the stepping motor of this embodiment, the reel makes one round with a cycle of 336 steps as described above, and since 21 symbols are arranged on the reel, 1 is made every 16 steps. The symbol will move. The excitation pattern is updated by the timer interrupt process (main) performed by the main CPU 41a. The count is the number of timer interrupt processes (main) until the next excitation pattern update. Yes, (count number) × 0.56 ms (timer interrupt processing (main) interval) is the excitation time (step rate) in which the excitation pattern of the step continues. The number of steps indicates the number of times that the corresponding excitation time is continuously applied. Further, φ1 to φ4 in the figure indicate the respective excitation phases, “ON” indicates the excited state, and “OFF” indicates the demagnetized state.

  As shown in FIG. 9, when starting the reel motors 32L, 32C, 32R, the main CPU 41a performs excitation in the rotational direction by the 1-2 phase excitation method described later from the state where each excitation phase φ1 to φ4 is demagnetized. Start. Specifically, (φ1, φ4) is excited in the first step, and (φ4), (φ4, φ3), (φ3), (φ3, φ2), (φ2), (φ2, In the order of φ1), (φ1)..., the excitation pattern is updated alternately for φ1-φ4 in two phases, one phase, and two phases.

  As shown in FIG. 8, the step rate of the first step is 20.16 ms, the step rate of the second step is 11.20 ms, the step rate of the third to ninth steps is 6.72 ms, and the step rate of the tenth step. Is 4.48 ms, and the step rate of each step is shortened so as to gradually approach the constant speed rotation step rate (2.24 ms). At this time, instead of reducing the step rate uniformly, the reel is smoothly accelerated by interlacing a long step rate and a short step rate and gradually increasing the short step rate. .

  In this embodiment, as shown in FIG. 9, the stop state is shifted to a constant speed state in 25 steps, and thereafter the 1-2 phase excitation method excitation pattern is updated at a step rate of 2.24 ms. The motor is driven to rotate each reel 2L, 2C, 2R. Specifically, along the rotation direction of the rotor 32a, (φ1, φ4), (φ4), (φ4, φ3), (φ3), (φ3, φ2), (φ2), (φ2, φ1), (φ1 ), (Φ1, φ4)... And the excitation pattern of φ1 to φ4 is alternately updated every two phases, one phase, two phases, one phase, two phases, and the rotor 32a is rotated. Thus, the reels 2L, 2C, 2R are rotated.

  Next, the control of the reel motor when the reel is stopped will be described. There are two types of control of the reel motor when the reel is stopped: normal stop control and low-speed stop control. The former is a control for stopping the reel at the target stop position as soon as possible after detecting the stop operation, that is, the reel is controlled. This is a control to stop the reel in a normal stop mode that requires a time that increases in proportion to the increase in the number of sliding frames as the time to stop.The latter is compared with the normal stop control after detecting the stop operation. As a time until the reel stops, the time required to stop the reel within the maximum pull-in range by the normal stop control (131. 04 to 164.64 ms) or less, and the time required to stop the reel at a specific number of sliding frames (2 frames in this embodiment) in the normal stop control (59 in this embodiment). The time (in this embodiment more than 92.96Ms) from 36, a control to stop the reels at a special stop mode requiring 116.48~150.08ms). For this reason, in the latter case, even when the stop operation is performed at the same timing as the normal stop control and stopped at the same stop position, the time required for the reel to stop after the stop operation is increased.

  In the normal stop control, as shown in FIGS. 11 and 12, after the stop operation is detected, the constant speed rotation step rate (2.24 ms) is maintained until the brake start position corresponding to the stop position is reached. When the brake start position is reached, a step rate (3.36 ms) longer than the step rate (2.24 ms) during constant speed rotation is applied, the brake is applied to decelerate the rotor 32a, and the next step (4 In the step before step), all-phase excitation for exciting all excitation phases φ1 to φ4 is started. As a result, sudden braking is applied to the rotor 32a, and as a result of overshoot (step out), the rotor 32a stops at the stop position.

  In this embodiment, after all-phase excitation is performed in the normal stop control, it slips by overshooting by 6 steps. Therefore, as shown in FIG. 12, the brake is applied at a step 7 steps before the stop position in the rotation direction. And all-phase excitation is started 6 steps before the stop position.

  In the normal stop control, as shown in FIG. 10, when the stop operation is performed at the timing of 32 steps to 47 steps before the stop position, that is, the two-frame slip in which the low speed stop control described later is performed, the stop operation is performed. After detection, the step rate is controlled to 2.24 ms, which is the same as the constant speed rotation for 25 to 40 steps, and in the next step, the step rate is controlled to 3.36 ms, which is longer than the constant speed rotation. Since it is controlled by excitation, it takes 59.36 ms to 92.96 ms to detect all phases after detecting the stop operation.

  The low-speed stop control further includes a low-speed stop control 1 and a low-speed stop control 2. Both the low-speed stop controls 1 and 2 are controls for slowly stopping the reel at a target stop position after detection of the stop operation, compared to the normal stop control. Even when the stop operation is performed at the same timing and stopped at the same stop position, the time required for the reel to stop after the stop operation is further increased.

  In this embodiment, the low-speed stop control 1 and the low-speed stop control 2 are applied only when two frames are selected as the number of sliding frames when the stop operation is performed. This is because if the low-speed stop control 1 or 2 is applied when the number of sliding frames is small, the rotation speed is suddenly reduced, and the vibration of the reel becomes conspicuous. On the other hand, the speed is low when the number of sliding frames is large. This is because when the stop control 1 and the low speed stop control 2 are applied, it becomes difficult to understand the difference from the normal stop control.

  In the low speed stop control 1, as shown in FIGS. 14 and 17, after the stop operation is detected, the constant speed rotation step rate (2) is reached until the brake start position corresponding to the stop position is reached as in the normal stop control. .24 ms), but a step rate (3.24 ms) longer than the step rate (2.24 ms) at constant speed rotation from the brake start position positioned further forward than the brake start position in the normal stop control. .36 ms) is applied and the brake is applied to start the deceleration of the rotor 32a. At this time, instead of increasing the step rate uniformly as shown in FIG. 13, by gradually interlacing a long step rate and a short step rate and gradually applying a long step rate, the rotor smoothly 32a is decelerated.

  Then, the step rate of 4.48 ms, which is twice the step rate of constant speed rotation (2.24 ms), is maintained until the step before the all-phase start position, and a longer step rate (5 .60 ms), and after further decelerating, all-phase excitation is started at the all-phase start position before the stop position (step two steps before) in the rotational direction. As a result, sudden braking is applied to the rotor 32a, and as a result of overshoot (step out), the rotor 32a stops at the stop position.

  In the low-speed stop control 1, since the rotational speed of the rotor 32a when starting full-phase excitation is slower and the inertial force is weaker than in the normal stop control, the all-phase start position of the low-speed stop control is the normal stop control. It is determined at a position closer to the stop position than the all-phase start position.

  In this embodiment, after all-phase excitation is performed in the low-speed stop control 1, since it slips by overshooting by two steps, as shown in FIG. 17, all phases are two steps before the stop position in the rotational direction. Excitation will be started.

  In the low speed stop control 1, as shown in FIG. 13, after the stop operation is detected, the step rate is controlled to the same step rate of 2.24 ms as the constant speed rotation for 0 to 15 steps. .36 ms, 2.24 ms × 3, 3.36 ms × 2, 2.24 ms × 2, 3.36 ms × 4, 4.48 ms × 17, 5.60 ms, and then controlled to all phase excitation Therefore, it takes 116.48 ms to 150.08 ms to detect all phases after detecting the stop operation. When stopping by two-frame slip in normal stop control, the time required for all-phase excitation after detection of the stop operation is 59.36 ms to 92.96 ms, even when stopping at the same stop position by the same two-frame slide As compared with the normal stop control, it takes a long time to stop after the stop operation is detected.

  In the low speed stop control 2, as shown in FIG. 16, the step rate of constant speed rotation (2.24 ms) is detected after the stop operation is detected until the brake start position corresponding to the stop position is reached as in the normal stop control. However, the step rate is longer than the step rate (2.24 ms) during constant speed rotation from the brake start position positioned further in front of the rotation direction than the brake start position of the normal stop control, and further lower speed. A step rate (5.56 ms) longer than the step rate (3.36 ms) at the brake start position of stop control 1 is applied, and the brake is applied to start the deceleration of the rotor 32a. At this time, as shown in FIG. 15, the step rate is not uniformly increased, but a long step rate is gradually applied while alternately interlacing a long step rate and a short step rate, thereby smoothly rotating the rotor. 32a is decelerated.

  After maintaining the step rate of 4.48 ms, which is twice the step rate of constant speed rotation (2.24 ms), until the step just before the start position of all phases, the step rate is gradually increased toward the step of the stop position. Decelerate and start all-phase excitation at the stop position. Thus, the rotor 32a that is gradually decelerated stops at the stop position without overshooting (step out).

  In the low-speed stop control 2, the brake is started at the same timing as the low-speed stop control 1, but at a stage earlier than the low-speed stop control 1 by making the step rate at the start of the brake longer than the low-speed stop control 1. In addition to decelerating, the vehicle gradually decelerates toward the stop position and stops at the stop position without overshooting. Therefore, it takes a longer time from the brake start to the stop than the low-speed stop control 1.

  In the present embodiment, after all-phase excitation is performed in the low-speed stop control 2 as described above, all-phase excitation is started at the stop position in order to stop without overshoot.

  In the low speed stop control 2, as shown in FIG. 15, after the stop operation is detected, the step rate is controlled to 2.24 ms, which is the same as the constant speed rotation, for 0 to 15 steps. Controlled to step rates of .60 ms, 2.24 ms × 2, 3.36 ms × 2, 2.24 ms × 1, 3.36 ms × 3, 4.48 ms × 18, 5.60 × 3, 8.96 × 2 ms After that, since it is controlled to all-phase excitation, 144.48.48 ms to 170.08 ms are required until the all-phase excitation after detecting the stop operation. When stopping by two-frame slip in normal stop control, the time required for all-phase excitation after detection of the stop operation is 59.36 ms to 92.96 ms, even when stopping at the same stop position by the same two-frame slide As compared with the normal stop control, it takes a long time to stop after the stop operation is detected. Further, when stopping at the low-speed stop control 1 by two-frame sliding, the time required for all-phase excitation after detection of the stop operation is 116.48 ms to 150.08 ms, and the stop operation is detected more than the low-speed stop control 1. It will take a long time to stop.

  As described above, in this embodiment, even when the stop operation is performed at the same timing and the stop operation is performed at the same position, when the low speed stop control is performed, the reel is decelerated compared to the normal stop control. The time required from the start to the stop becomes longer, and the stop position is reached slowly, so that the stop mode can be diversified.

  In addition, the low-speed stop control further includes a plurality of types of low-speed stop controls with different time required for stopping after detection of a stop operation, and the stop mode can be further diversified.

  In addition, when performing low-speed stop control, all-phase excitation starts at a position closer to the position where all-phase excitation starts in normal stop control, so that deceleration starts earlier than in normal stop control. Even if low-speed stop control with weak inertia force is performed, it is possible to stop at the same stop position as normal stop control, and the stop position varies depending on whether normal stop control or low-speed stop control is performed. Can be prevented.

  Even when low-speed stop control is performed, control is performed at the same step rate as constant-speed rotation until the brake start position is reached after a stop operation is detected. Regardless of the number of steps in which the operation is detected, if the number of sliding frames is the same, low-speed stop control can be performed with common control, and control can be prevented from becoming more complicated than necessary.

  The low-speed stop control shown in the present embodiment is a control method other than the above-excited control method as long as it is a control for slowly stopping the reel at a target stop position as compared with the normal stop control after detecting the stop operation. It may be performed by the control. For example, by making the excitation pattern different from the constant speed rotation at a stage earlier than the normal stop control, for example, by exciting the three excitation phases while keeping the excitation phase to be demagnetized originally excited, After decelerating the reel, it may be possible to lengthen the time required to stop than usual by performing all-phase excitation.

  In this embodiment, both the normal stop control and the low-speed stop control are configured to continue all-phase excitation for the same time after the start of all-phase excitation. The inertial force at the start of all-phase excitation is also weak, and the reel can be stopped reliably without continuing all-phase excitation for the same time as the normal stop control. The time until all the excitation phases are turned off after the start of all-phase excitation may be set shorter than the control. Moreover, if all phases are excited as in the case of the low speed stop control 2, it is sufficiently decelerated, and if it stops naturally, all phases are not excited and only all excitation phases are turned off. But it ’s okay.

  For example, when the hopper motor 34b is accompanied by a medal payout, the voltage is insufficient and the medal payout is waited until the all-phase excitation is released. As described above, the normal stop control is performed in the low speed stop control. By setting the all-phase excitation time shorter or not performing all-phase excitation, the time until the medal payout operation can be shortened when performing the low-speed stop control.

  Next, the contents of control executed by the main CPU 41a in connection with the low speed stop control will be described.

  FIG. 21 is a flowchart showing the control contents of the game process executed by the main CPU 41a.

  In the game process, a BET process (Sd1), an internal lottery process (Sd2), a reel rotation process (Sd3), a winning determination process (Sd4), a payout process (Sd5), and a game end process (Sd6) are sequentially executed. When the end-time process ends, the process returns to the BET process again.

  In the BET process in the step of Sd1, the process waits in a state where the bet number can be set, sets a predetermined number of bets according to the gaming state, and executes a process of determining the bet number when the start switch 7 is operated. To do.

  In the internal lottery process in step Sd2, a random number for internal lottery is extracted simultaneously with the start of the game by the detection of the start switch 7 in step Sd1, and the winning of each above-described combination is permitted based on the extracted random number value. Process to determine whether or not. In this internal lottery process, a winning flag is set in the RAM 41c based on the respective lottery results.

  In the reel rotation process in the step of Sd3, the process of rotating each reel 2L, 2C, 2R and the operation of the corresponding reel 2L, 2C, 2R in response to the operation of the stop switch 8L, 8C, 8R detected by the player are detected. A process for stopping the rotation is executed. In the reel rotation process, a low-speed stop determination process for determining whether or not to execute the low-speed stop control before starting the reel rotation is executed.

  In the winning determination process in the step Sd4, when it is determined in the step Sd3 that the rotation of all the reels 2L, 2C, and 2R is stopped, the winning is determined according to the display result derived for each reel 2L, 2C, and 2R. A process of determining whether or not it has occurred is executed.

  In the payout process in step Sd5, when it is determined that a prize is generated in step Sd4, processing such as addition of credits and payout of medals is performed based on the number of payouts according to the win.

  In the game end process in the step of Sd6, a process of setting a gaming state in preparation for the next game is executed.

  FIG. 22 is a flowchart showing the control contents of the reel rotation process executed by the CPU 41a in step Sd3.

  In the reel rotation process, first, it is determined whether or not a wait time (about 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Si1), and the wait time must have elapsed. For example, it waits until the wait time elapses.

  If the wait time has elapsed in the Si1 step, a new wait time is set (Si2).

  Next, after performing a low speed stop determination process for determining whether or not to apply the low speed stop control (Si3), a setting at the time of starting the rotation of the reel motor is performed and the rotation of the reel is started (Si4). Then, a sliding frame number setting process for setting the number of sliding frames in the virtual sliding frame table for each rotating reel is performed (Si5), and a setting at the time of completion of stop preparation is performed (Si6). As a result, the stop operation can be validated, and then the stop operation becomes valid when a constant-speed rotation of the reel is detected in the processing at the time of passing through the origin of a timer interrupt process described later.

  Next, it is determined whether or not an operation of any one of the stop switches 8L, 8C, 8R is detected (Si7). If no operation of any stop switch is detected, a reel rotation error (over a certain period of time). Then, it is determined whether or not an error determined when the reel reference position is not detected by the reel sensor 33 (Si8). If no reel rotation error has occurred, an insertion error (medal insertion) is further performed. Whether or not a medal insertion was detected during a period other than the permitted period, and whether or not a payout error (medal payout was detected during a period other than the permitted period) (Error determined in the case) is determined (Si9, Si10), and any error in the steps of Si8 to Si10 If raw also is determined, the process returns to the step of Si7.

  If it is determined that a loading error has occurred in the Si9 step, or if a dispensing error is determined in the Si10 step, an error code indicating a loading / dispensing error during reel rotation is set in the register (Si11). ), And shifts to error processing (Si12). When the error is released, the process returns to the Si6 step again.

  If it is determined in step Si8 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (Si13), and the process proceeds to error processing (Si4). Along with this, the rotation of the reels is also temporarily stopped. When the error is released, the process returns to the Si4 step again and the reel rotation is resumed.

  If any stop switch operation is detected in the Si7 step, the number of steps from the reel reference position at that time in the reel motor corresponding to the stop switch (the number of steps to be the stop operation position) is calculated. After obtaining and setting the work corresponding to the stop reel (Si15), the process waits until the rotation of the reel corresponding to the stop operation stops (Si16).

  Then, when the rotation of the reels corresponding to the stop operation is stopped, it is determined whether or not all the reels are stopped (Si17). If all the reels are not stopped, the process returns to the Si5 step, and all the reels are If it is stopped, the reel rotation process is terminated and the process returns to the flowchart of FIG.

  As described above, in the reel rotation processing, after the rotation of the reels 2L, 2C, and 2R is started, the rotation of the reels for which the stop operation has not been detected is continued until the operation of the stop switches 8L, 8C, and 8R is detected. Then, on the condition that the operation of the stop switches 8L, 8C, and 8R is detected, control is performed to stop the display result on the corresponding reel. Even if the reel rotation temporarily stops due to the occurrence of a reel rotation error, the stop operation is still detected until the operation of the stop switches 8L, 8C, and 8R is detected after the reel rotation is restarted. Control is performed to stop the display result of the corresponding reels on the condition that the rotation of the reels that have not been continued is continued and the operation of the stop switches 8L, 8C, and 8R is detected.

  FIG. 23 is a flowchart showing the control content of the low-speed stop determination process performed by the main CPU 41a.

  In the low-speed stop determination process, first, it is determined whether or not a bonus is being performed (Si51) and whether or not a special combination confirmation notification has already been performed (Si52).

  If it is determined in step Si51 that the bonus is being performed, or if it is determined in step Si52 that the special role has been confirmed, the process is terminated. Control does not apply.

  On the other hand, if it is determined that the bonus is not being given in the Si51 step, and it is determined that the special role is not confirmed in the Si52 step, it is determined whether or not the cherry is won in the internal lottery ( Si53), even when it is determined that the cherry is not won, the low speed stop control is not applied.

  If it is determined in the step of Si53 that the cherry is won in the internal lottery, whether the low speed stop control 1 is performed with the probability shown in FIG. 24, the low speed stop control 2 is performed, or the normal stop control is performed. , A low speed stop lottery is performed (Si54).

  Then, it is determined whether or not the low speed stop control 1 or the low speed stop control 2 is won (Si55). When the winning of the low speed stop control 1 is determined in the step of Si55, the low speed stop control flag indicating the low speed stop control 1 is set. When the winning of the low speed stop control 2 is determined, the low speed stop control 2 Is set (Si56), and when neither the low speed stop control 1 nor the low speed stop control 2 is won, the low speed stop control flag is not set.

  In the low speed stop lottery, as shown in FIG. 24, when only the cherry is won, the probability of winning either of the low speed stop controls 1 and 2 (low speed stop control 1: 10%, low speed stop control 2: 5% The probability of winning either low speed stop control 1 or 2 when the cherry is winning with a special role (low speed stop control 1: 30%, low speed stop control 2: 30%) is set higher. .

  In addition, when only cherry is elected, cherry is elected with special role than the ratio (1/3 (5% / (5% + 10%)) of the slow stop control 2 of the slow stop controls 1 and 2 is won. In this case, the ratio (1/2 (30% / (30% + 30%)) in which the low-speed stop control 2 is selected among the low-speed stop controls 1 and 2 is set high.

  When the low-speed stop control flag indicating the low-speed stop control 1 is set, when two reels are selected as the number of sliding frames when the reel is stopped by a stop operation thereafter, the low-speed stop control 1 is applied. Become. When the low speed stop control flag indicating the low speed stop control 2 is set, the low speed stop control 2 is applied when two frames are selected as the number of sliding frames when the reel is stopped by a stop operation thereafter. It will be.

  If the low-speed stop control flag is not set, or if the low-speed stop control flag is set, but 0, 1, 3, or 4 is selected as the number of sliding frames, the reel is stopped by a stop operation. In this case, the normal stop control is applied.

  As described above, since the low speed stop control flag is not set during the bonus or after the bonus confirmation notification, the low speed stop control is performed after the bonus or after the bonus confirmation notification even if the cherry is won. There is nothing.

  FIG. 25 is a flowchart showing the control contents of the sliding frame number setting process executed by the main CPU 41a in the step of Si5.

  First, in the sliding frame number setting process, it is determined whether or not it is the first stop in the step of Si101, that is, whether or not all the reels are rotating. If it is the first stop, the process proceeds to the step of Si102.

  In step S102, the table index is referred to, the sliding frame number data corresponding to the result of the internal lottery is selected, the selected sliding frame number data is expanded, and the sliding number of the left reel in the virtual sliding frame table is stored. After performing the sliding frame number data development processing, the process proceeds to step Si103, and the stop position where the winning combination is aligned on the winning line from the stop position by the sliding frame number of 0 to 4 for each stop operation position for the middle reel and the right reel. After performing the stop position search process for storing the number of sliding frames at the stop position acquired by the search in the virtual sliding frame table, the number of sliding frames is set, and the process returns to the flowchart of FIG.

  If it is not the first stop in the Si101 step, the process proceeds to the Si103 step, and for each reel, a stop position where the winning combination is aligned on the winning line from the stop position by the number of sliding frames of 0 to 4 for each stop operation position. And a stop position search process for storing the number of sliding frames at the stop position acquired by the search in the virtual sliding frame table, the sliding frame number setting process is terminated, and the process returns to the flowchart of FIG.

  FIG. 26 is a flowchart showing the control contents of the stop position search process executed by the CPU 41a in the step of Si103.

  First, in the stop position search process, a reel to be processed is set in step Si301. That is, the reels that are not yet processed among the reels that are rotating (in the case of the first stop, the left reel has been processed by the sliding frame number data expansion process, so This is a reel, and if it is after the second stop, it is set as the target reel), and the process proceeds to step Si302.

  In the step of Si302, a stop position pointer indicating a stop position to be processed is set to 0, and whether or not an abnormal winning occurs when the process proceeds to the step of Si303 and reaches the stop position to be processed. The virtual winning determination is performed, and the process proceeds to step S304 to determine whether the result of the virtual winning determination is an abnormal winning.

  If it is not an abnormal winning in the step of Si304, the process proceeds to the step of Si305, further performs a prohibition position determination for determining whether or not the stop prohibition position is reached, and proceeds to the step of Si306, and as a result of the prohibition position determination, the stop prohibition position is determined. It is determined whether or not.

  If it is not the stop prohibition position in the step of Si306, the process proceeds to the step of Si308, and if it is determined that the abnormal winning prize is determined in the step of Si304, or if it is determined that the stop prohibition position is determined in the step of Si306, Then, after setting a stop prohibition position flag indicating a stop prohibition position corresponding to the stop position indicated by the stop position pointer, the process proceeds to step Si308.

  In the step of Si308, the stop position pointer is advanced by 1 and the process proceeds to the step of Si309 to determine whether or not the stop position pointer is 21, and if the stop position pointer is not 21, the process returns to the step of Si303 to stop. If it is determined that the pointer is 21, that is, the determination for all the area numbers has been completed, the process proceeds to step S310.

  In the step of Si310, the stop operation position pointer indicating the stop operation position to be processed is set to 0, the process proceeds to the step of Si311 and the order corresponding to the winning combination (2, 0, 1 in the case of cherry in particular). The number of sliding frames is acquired in the order of (3, 4), and the process proceeds to step S312.

  In step Si312, the stop position based on the number of sliding frames acquired in Si311 is acquired, and the process proceeds to step Si313 to determine whether the acquired stop position is a stop prohibition position, that is, whether a stop prohibition position flag is set. To do.

  If it is determined in the Si 313 step that the position is the stop prohibited position, the process returns to the Si 311 step. If it is determined that the position is not the stop prohibited position, the process proceeds to the Si 314 step.

  In the step of Si314, it is determined whether or not the winning combination is aligned on the winning line when the acquired stop position is reached. If the winning combination is not aligned on the winning line, the process proceeds to the step of Si315, and the winning line is selected on the winning line. If it is determined that the combination is complete, the process proceeds to step Si316.

  In the step of Si315, it is determined whether or not the stop positions are compared for all the sliding frame numbers from 0 to 4, and if the comparison of the stopping positions is completed for all the sliding frame numbers from 0 to 4, the process of Si316 is completed. Proceed to the step, and if the comparison of the stop positions is not completed for all the sliding frames from 0 to 4, the process returns to the Si311 step.

  In the step of Si316, last in the step of Si312 corresponding to the corresponding stop operation position (area number indicated by the stop operation position pointer) of the corresponding reel (reel set as the target reel) in the virtual sliding frame number table. The acquired number of sliding frames at the stop position is stored, and the process proceeds to step Si317. In addition, when the number of sliding symbols that become the stop position acquired last is the stop prohibiting position, the number of sliding symbols that are not the stopping prohibition position among the number of sliding symbols that become the stopping position acquired before that is stored. .

  In the Si317 step, the stop operation position pointer is advanced by 1 and the process proceeds to the Si318 step to determine whether or not the stop operation position pointer is 21, and if the stop operation position pointer is not 21, the process returns to the Si311 step. If the stop operation position pointer is 21, that is, if it is determined that all the region numbers 0 to 20 have been determined, the process proceeds to step Si319.

  In step S319, it is determined whether there is an unprocessed rotating reel. If there is an unprocessed rotating reel, the process returns to step Si301. If there is no unprocessed rotating reel, the number of sliding frames is updated. To return to the flowchart shown in FIG.

  27 and 28 are flowcharts showing the control contents of the timer interrupt process (main) executed by the main CPU 41a interrupting and executing the game process at intervals of 0.56 ms.

  In the timer interruption process, first, interruption is prohibited (Sk1). That is, the execution of another interrupt process during the execution of the timer interrupt process is prohibited. Then, the register in use is saved in the stack area (Sk2).

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process is advanced by 1 from the four types of timer interrupts 1 to 4 (Sk3). In the step of Sk3, 1 is added when the branch counter value is 0 to 2, and is updated to 0 when the counter value is 3. That is, the branch counter value loops in the order of 0 → 1 → 2 → 3 → 0... Each time the timer interrupt process is executed.

  Next, referring to the counter value for branching, it is determined whether it is 2 or 3, that is, timer interrupt 3 or timer interrupt 4 (Sk4), and if it is not timer interrupt 3 or timer interrupt 4, that is, timer interrupt In the case of 1 or timer interrupt 2, it is checked whether the reel motors 32L, 32C, 32R are started or whether they are rotating at a constant speed, and whether the reel motors 32L, 32C, 32R are started or are rotating at a constant speed. For example, the motor phase signal output process for outputting the phase signal data changed in the motor step process of Sk8 described later and the phase signal data changed in the final stop process of Sk24 described later is executed (Sk5).

  Next, referring to the counter value for branching, it is determined whether or not it is 1, that is, timer interrupt 2 (Sk6). If it is not timer interrupt 2, that is, timer interrupt 1, the reel motor Reel start processing (Sk7) for controlling the step time interval when starting 32L, 32C, 32R, motor step processing (Sk8) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, the motor phase signal standby process (Sk9) for changing the phase signal to one-phase excitation after a certain time has been sequentially executed, and then the register saved in the stack area at Sk2 is restored (Sk20). The interrupt prohibited in the step is permitted (Sk21), and the process returns to the state before the interrupt.

  In the case of timer interrupt 2 in the step of Sk6, LED dynamic display processing for dynamically lighting various indicators (Sk10), control signal output processing for outputting data such as lighting signals of various LEDs to the output port, etc. (Sk11), random number update process for updating various software random numbers (Sk12), time counter update process for updating various time counters (Sk13), command transmission for transmitting commands stored in the command queue to the effect control board 90 After the processing (Sk14) and the external output signal update process (Sk15) for updating the external output signal are sequentially executed, the registers saved in the stack area in Sk2 are restored (Sk20), and the interrupts prohibited in the step of Sk1 are permitted. (Sk21), the process returns to the state before the interruption.

  If it is timer interrupt 3 or timer interrupt 4 in the step of Sk4, the branch counter value is further referred to to determine whether it is 3 or not, ie, timer interrupt 4 (Sk16). If it is not interrupt 4, that is, timer interrupt 3, port input processing (Sk17) for inputting detection data of various switches from the input port, passing the origin of the reels 2L, 2C, 2R during rotation (reel reference) (Passing position) is detected, the occurrence of a reel rotation error is detected, whether stop preparation is completed (stop preparation completion code is set), stop preparation is complete, and If it is rotating at high speed, the process at the time of passing through the origin (Sk18) that validates the operation of the stop switch corresponding to the rotating reel, and the various scans based on the detection signals of the various switches. After sequentially executing the switch input determination process (Sk19) for determining whether or not the switch satisfies the detection condition, the register saved in the stack area in Sk2 is restored (Sk20), and the interrupts prohibited in the Sk1 step Is permitted (Sk21) and the process returns to the state before the interruption.

  If the timer interrupt is 4 in the step of Sk16, when the stop operation position is stored in the work of the stop reel with the detection of the stop switches 8L, 8C, 8R or the automatic stop control, the work of the stop reel The stop position is determined from the stop operation position stored in, the number of steps after which the stop should be calculated is calculated, and if the low speed stop control flag is set, the number of steps corresponding to 2 frames is low speed stop The stop switch process (Sk22) for instructing the execution of the control, the number of steps until the stop calculated by the stop switch process is counted, and the normal stop control, the low speed stop control 1 or the low speed stop control 2 is directed toward the stop timing. Stop process for applying the brake by controlling the excitation time (Sk23), final stop process for all-phase excitation when the stop time step is reached SK24) was sequentially executes, returning the registers saved in the stack area in Sk2 (SK20), allow interruption prohibited at step Sk1 (SK21), return to the process before the interrupt process.

  FIG. 29 is a flowchart showing the control content of the stop switch process executed by the CPU 41a in the timer interrupt 4 of the timer interrupt process described above.

  In the stop switch process, first, for all reels in the order of left, middle, and right, whether or not a stop operation position is set for the work on the corresponding reel, that is, a stop operation has been detected or stopped by automatic stop. Is determined (Sk101, Sk102), and if no stop operation has been detected for all reels or if no stop has been instructed, the stop switch process is terminated and the process returns to the flowchart of FIG.

  In addition, if any stop operation of the reel is detected in the step of Sk101 or if the stop of the reel is instructed, the process proceeds to the step of Sk103.

  In step Sk103, the virtual sliding frame table corresponding to the reel is referred to, and the region number serving as the stop position is specified from the region number including the step number of the stop operation position set for the work corresponding to the stop reel. .

  Next, it is determined whether or not the low speed stop control has already been executed in the game (Sk104). Whether or not the low-speed stop control has already been executed is determined based on whether or not an executed flag to be described later is set. If it is determined in step Sk104 that the low speed stop control has already been executed, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If the low speed stop control has not been executed in the step of Sk104, it is determined whether or not the number of steps specified in the step of Sk103 is the number of steps (32 to 47) corresponding to two frames (Sk105). If the number of steps does not correspond to two frames, the stop switch process is terminated and the process returns to the flowchart of FIG. 28. If the number of steps corresponds to two frames, is the low-speed stop control 1 selected in the low-speed stop lottery? That is, it is determined whether or not the low speed stop control flag indicating the low speed stop control 1 is set (Sk106).

  If the low-speed stop control 1 is elected, the low-speed stop execution flag 1 for instructing the execution of the low-speed stop control 1 is set in the RAM 41c, and an executed flag for moistening that the low-speed stop control has been executed is stored in the RAM 41c. The setting is made (Sk107, Sk108), the stop switch process is terminated, and the process returns to the flowchart of FIG.

  On the other hand, if the low speed stop control 1 is not won in the step of Sk106, it is determined whether the low speed stop control 2 is won in the low speed stop lottery, that is, whether or not the low speed stop control flag indicating the low speed stop control 2 is set. Determine (Sk109).

  If the low-speed stop control 2 is elected, the low-speed stop execution flag 2 for instructing the execution of the low-speed stop control 2 is set in the RAM 41c, and the executed flag indicating that the low-speed stop control has been executed is set in the RAM 41c. Then, the stop switch process is terminated and the process returns to the flowchart of FIG.

  If the low speed stop control 2 has not been won in step Sk106, the stop switch process is terminated as it is, and the process returns to the flowchart of FIG.

  When the low speed stop execution flag 1 is set in the stop switch process, the excitation time is controlled according to the low speed stop control 1 in the subsequent stop process, and the low speed stop execution flag 2 is set in the stop switch process. In such a case, the excitation time is controlled in accordance with the low-speed stop control 2 in the subsequent stop process.

  Further, in the stop switch process, even when the low speed stop control flag is set, if the low speed stop control is already executed in the game, the low speed stop control is not instructed. Thus, when the low speed stop control is executed on any of the reels, the low speed stop control is not executed on the subsequent reels.

  Next, the number of sliding symbols selected for each reel stop operation position at the time of cherry winning in which low speed stop control can be performed will be described.

  FIG. 30 is a diagram showing the number of sliding symbols of each reel selected when a cherry is won in a state where no bonus is carried over.

  The number of sliding frames on the left reel applied at the time of the first stop is the number of sliding frames developed using the sliding frame number data corresponding to the cherry. As shown in FIG. Slide pieces that draw “cherry” into the winning lines L2 to L5 with respect to the winning lines L2 to L5, that is, the area numbers 0 to 9 and 18 to 20 that can be drawn into the upper or lower stage. The number of the stop operation positions at which “Cherry” can be drawn into the pay lines L2 to L5 is determined by two frames.

  In addition, “cherry” is drawn to the winning lines L2 to L5 in the drawing range of up to 4 frames, and the area numbers 10 to 17 are set to 2 frames. For this reason, when the left reel is the first stop reel when the cherry is won, two frames that can be controlled at a low speed at a ratio of 12/21 are selected as the number of sliding frames. It has become.

  The number of sliding frames of the middle reel applied at the time of the first stop is the number of sliding frames specified by the stop position search process, and the “bell” constituting the cherry in the order of 2, 0, 1, 3, 4 is won. As a result of searching for the number of sliding frames to be drawn into the line, as shown in FIG. 30 (b), as the number of sliding frames to draw “bell” constituting the cherry into any of the winning lines L1 to L5, region numbers 1 to 3, Two frames are specified for 5-7, 10-12, 14-16, and 18-20, and 0 frames are specified for area numbers 0, 4, 8, 9, 13, and 17. For this reason, when the middle reel becomes the first stop reel when the cherry is won, two frames capable of performing the low speed stop control at a ratio of 15/21 are selected as the number of sliding frames. It has become.

  The number of sliding frames on the right reel applied at the time of the first stop is the number of sliding frames specified by the stop position search process, and any symbol is drawn into the winning line in the order of 2, 0, 1, 3, 4 As a result of searching for the number of sliding frames, two frames are specified for the region numbers 0 to 20, as shown in FIG. Therefore, when the right reel becomes the first stop reel when the cherry is elected, the ratio of 21/21, that is, two frames that can reliably perform the low speed stop control, is the number of sliding frames. It is to be selected.

  As described above, when the cherry is selected, the low-speed stop control can be performed at a rate larger than the case where two frames are selected as the number of sliding frames for the left reel and the middle reel as the number of sliding frames for the right reel at the first stop. Two possible frames are selected.

  Although not specifically shown, the low-speed stop control can be performed at a rate greater than the number of sliding frames for the right reel and the number of sliding frames for the left reel and the middle reel even after the second stop. Two possible frames are selected.

  For this reason, in this embodiment, when the cherry is elected, the ratio of stopping at two frames when the right reel stops is higher than that of the left reel or the middle reel.

  As described above, in the slot machine 1 according to the present embodiment, it is possible to perform the low-speed stop control for slowly stopping the reel at the target stop position after detecting the stop operation as compared with the normal stop control. If the number of sliding frames is small, the rotation speed will drop rapidly and the reel vibration will be noticeable. On the other hand, if the number of sliding frames is large, the difference from normal stop control will be difficult to understand. The number of sliding frames suitable for is limited.

  In this embodiment, the low speed stop control is performed only when two frames suitable for the low speed stop control are selected as the number of sliding frames, but the number of sliding frames is determined when the reel is stopped. The number of sliding symbols is limited to the number of sliding symbols suitable for low-speed stop control depending on the timing of the stop operation, and low-speed stop control is performed. Since opportunities are reduced, it is impossible to sufficiently enhance the interest of the player by providing low-speed stop control.

  For this reason, in this embodiment, the symbols (the left reel cherry and the middle reel bell) subject to winning determination in a specific reel (left reel, middle reel) only stop on one winning line and remain. Regardless of the symbol that has been stopped on the reels, a low speed stop control is performed when the winning cherry is won, and at the time of winning the cherry, the stopped symbol does not affect the reels other than the specific reel, that is, the cherry winning. Selects the number of sliding frames of two frames that can be controlled at low speed at a higher rate than the reel that restricts the number of sliding frames to pull in a specific reel, that is, “cherry” or “bell”. It is possible to increase the chances that the low speed stop control is performed, and it is possible to effectively enhance the interest of the low speed stop control. .

  When there is an area where stop operation positions where two frames capable of performing the low speed stop control are selected and a stop operation position where two frames are selected are sparse in any reel May be arranged such that a symbol (a conspicuous symbol) is placed in an area where the stop operation position where two frames are selected is concentrated, and the symbol that is the indicator is notified. As a result, it is possible to prompt the user to perform a stop operation aiming at a region where the stop operation positions where two frames are selected are concentrated, thereby further increasing the chance of performing the low speed stop control.

  In addition, in this embodiment, as a special prize that will be awarded regardless of the symbols stopped on the remaining reels, the symbols subject to winning determination on a specific reel only stop on one winning line. One of the reels has a symbol for winning determination beyond the draw range (cherry on the left reel), and the other reel has a symbol for winning determination within the draw range. On the other hand, in the case of one reel among the specific reels, in order to stop the target symbol on the winning line, it is necessary to perform a stop operation at the timing of the drawing range of the symbol, For other reels, cherries that can stop the target symbol regardless of the timing of the stop operation are applied as special prizes. , One of the specific reels, that is, the symbol that is subject to winning determination is placed beyond the pulling range, and within the maximum pulling range to pull the target symbol to the maximum within the maximum pulling range depending on the operation timing The number of sliding frames of 2 frames capable of performing the low speed stop control is selected at a higher rate than the reels that need to select the number of sliding frames other than 2 frames of 0 to 4 frames of Therefore, even when the special prize having the above-described configuration is applied, it is possible to surely increase the opportunities for performing the low speed stop control.

  Also, in this embodiment, when winning a cherry, a sliding frame with the highest priority given to two frames capable of low-speed stop control for reels other than a specific reel, that is, a right reel whose stop symbol does not affect the winning of cherry. The number of sliding frames is selected by the control method for retrieving the number, and the number of sliding frames is selected in advance so that two frames are selected as the number of sliding frames as much as possible according to the stop status or stop position of other reels. It is preferable because the ratio of the number of sliding frames of two frames can be increased without preparing, but it is preferable that the number of sliding frames of two frames is also increased for reels other than a specific reel at the time of winning the cherry. The number of sliding frames with a high ratio is prepared in advance, and stop control is performed using the number of sliding frames. It may be configured to increase.

  Also, in this embodiment, when winning a special winning cherry, when a special combination with a shift to BB or RB advantageous to the player is won, than when a special combination is not won If the low-speed stop control is applied with a high probability and the low-speed stop control is applied, that is, if the reel stops more slowly than usual after the stop operation, it is won as a special role Since the possibility increases, the player's expectation for winning the special role can be increased.

  In addition, Cherry, which is a special prize, has the possibility of winning simultaneously with a special role, so the player's expectation associated with the possibility of winning a special role suggested by the winning of Cherry will be slowed down thereafter. It can be further increased by control.

  Also, if the special combination with the transition to BB or RB advantageous to the player is selected among the low-speed stop control 1 and the low-speed stop control 2 that stops more slowly than the low-speed stop control, the special combination is won. The low-speed stop control 2 is elected at a higher ratio than the case where the low-speed stop control 1 is applied. When the reel stops more slowly than usual after the stop operation, the low-speed stop control 1 is applied. When low-speed stop control 2 is applied, that is, when the reels stop more slowly, the possibility of winning the special role increases. When low-speed stop control is applied, pay attention to the speed. Can be made.

  In this embodiment, it is a configuration that suggests the possibility of winning the special role by performing the low speed stop control, but any configuration that suggests some information to the player by performing the low speed stop control may be used. For example, a configuration that suggests a possibility that a right to shift to an advantageous gaming state or a lottery to determine whether or not to shift to an advantageous gaming state is preferentially given than usual may be used. . Furthermore, it may be configured to suggest that a setting value that is more advantageous to the player among a plurality of setting values is set for the player.

  Further, in this embodiment, when the cherry is elected and it is determined to perform the low speed stop control, when the low speed stop control is performed for any of the reels, the remaining reels are subsequently stopped. Even when the number of sliding frames of 2 frames is selected as the number of sliding frames, the low speed stop control is not performed. This is because, for example, when low speed stop control is similarly performed on all reels, it is difficult to identify whether low speed stop control is performed or normal stop control is performed. When the low speed stop control is performed on any of the reels as described above, the normal stop control and the low speed stop control are always mixed by not performing the low speed stop control for the remaining reels. By doing so, the difference becomes clear and the player can be surely recognized that the low-speed stop control has been performed.

  In this embodiment, when the low speed stop control is performed on any one of the three reels, the low speed stop control is not performed on the other reels, but the low speed stop is performed on a plurality of reels. The configuration may be such that the control is performed, and in such a configuration, the possibility of winning the special role suggested according to the number of reels for which the low speed stop control is performed may be changed.

  Further, in this embodiment, during the bonus period or after the special role is confirmed and informed, the period until the special part wins, that is, the period during which there is no suggestion even if the low speed stop control is performed, is the low speed. Stop control is not performed, and it is possible to prevent the digestion efficiency of the gaming state from being reduced by performing the low speed stop control during such a period.

  In the present embodiment, when the sub CPU 91a receives a reel stop command indicating the stop of the reel from the main CPU 41a, a reel stop effect such as output of a reel stop sound is executed. On the other hand, it is possible to specify whether the main CPU 41a is the normal stop control, the low-speed stop control 1 or the low-speed stop control 2 from the reel stop command transmitted to the sub CPU 91a when the reels are stopped. The sub CPU 91a receives the reel stop command, and executes the reel stop effect different from the normal stop control when the low speed stop control 1 or 2 is specified from the received reel stop command.

  In the reel stop effect, for example, in the case of the normal stop control, the first stop sound having a predetermined length is output, whereas in the case of the low speed stop control 1, the second longer than the predetermined length is output. It is sufficient to output a stop sound. In this case, in the case of the low speed stop control 2, it is preferable to output a second stop sound that is longer than the second stop sound output in the case of the low speed stop control 1. Also, in the case of low speed stop control, the same sound effect as in normal stop control may be extended and output slowly, and in this way, the time until stop at the same number of sliding frames becomes longer. Can be recognized intuitively.

  Note that these reel stop effects are not limited to voice effects, but may be recognized as a longer time to stop at the same number of sliding frames depending on images, moving images, and LED lighting modes.

  Further, in this embodiment, the sub CPU 91a determines the result of the low speed stop lottery, that is, whether the low speed stop control 1 is executed, the low speed stop control 2 is executed, or the low speed stop control is not executed. When a command is received, the result of the low-speed stop lottery indicated by the low-speed stop determination command is stored, and all reels in the game in which the low-speed stop control 1 or the low-speed stop control 2 is stored are stored. When the reel stop command is received and the low speed stop control 1 or 2 is not specified from any of the received stop commands, that is, even though the low speed lottery is won, two frames are selected as the number of sliding frames. If the low-speed stop control is not performed because it was not found, it is not determined that the low-speed stop control is to be performed. If a slow stop control is performed to perform an effect special never executed.

  In the special effect, the lighting mode of the reel LED 55 that irradiates the reels 2L, 2C, and 2R from behind is changed to a special mode.

  The special effect is not limited to the effect mode in which the lighting mode of the reel LED 55 is changed, but it is possible to recognize that the low-speed stop control is not performed although it is determined that the low-speed stop control is performed. The display mode of the liquid crystal display 51, the sound output mode, and the lighting mode of the LED lighting mode may be applied.

  Further, in this embodiment, an effect that is not executed when the low speed stop control is not determined as a special effect or when the low speed stop control is performed on any reel is applied. However, for example, a special effect may be executed exceptionally when the low speed stop control is performed on the condition that the special role is elected, and such a configuration is normal. For example, a special effect that is executed only when the low-speed stop control is not performed is executed when the low-speed stop control is performed, so that it is possible to indicate that the special combination is won.

  Although the embodiments of the present invention have been described with reference to the drawings, the present invention is not limited to these embodiments, and modifications and additions within the scope of the present invention are included in the present invention. Needless to say.

  In the above embodiment, as the special derivation control, the low speed stop control is applied to stop the reel at the target stop position more slowly than the normal stop control after detecting the stop operation. In order to perform control for deriving the display result in a special stop mode, and in performing control for deriving the display result in a special stop mode, only a part of the maximum number of sliding frames is included in the maximum number of sliding frames. Any control may be used as long as it is suitable for the control. For example, control that stops the reel while vibrating it up and down (so-called bound stop) may be applied as the special derivation control.

  In the above embodiment, two frames are applied as the number of sliding frames suitable for the special derivation control. However, the number of sliding frames suitable for the special derivation control is not limited to this. There may be a plurality of sliding frames suitable for.

  In the above embodiment, the number of sliding frames suitable for low-speed stop control is set to 2 frames with a little margin in order to surely eliminate the possibility that the vibration of the reel will be noticeable due to a sudden drop in the rotation speed. However, one frame may be applied as the number of sliding frames, which is a condition for performing the low speed stop control, and if it is less than one frame, it is difficult to suppress the vibration of the reel due to a sudden drop in the rotational speed. However, if one frame is used, the vibration from the reel can be suppressed and the difference from the normal stop control can be made clearer.

  In the above embodiment, if a cherry stops on the left reel and a bell stops on the middle reel on any winning line, the cherry that wins regardless of the symbol stopped on the right reel is applied as a special prize. However, in any one of the reels, a special symbol is stopped on the winning line and a winning combination (for example, Cherry-ANY-ANY) is applied as a special prize regardless of the symbols stopped on other reels. May be.

  Also, as a special prize, Cherry 1 consisting of a combination of “Cherry-Bell-ANY” (“Bell” in the middle reel is a pattern placed in the pull-in range) and “Cherry-Black 7-ANY” (in the middle reel) “Black 7” is a cherry 2 made of a combination of symbols placed beyond the pull-in range), and as a lottery target for internal lottery, only a cherry 1 is won alone, and cherry 1 It is controlled so that only “Cherry-Bell-ANY” can be aligned on the winning line when a weak cherry is won, while a strong cherry is won. If a stop operation is performed within a range where “Black 7” can be pulled into the winning line on the reel, “Cherry-Black 7-ANY” can be aligned on the winning line. And when the stop operation is performed outside the range where “Black 7” can be pulled into the winning line in the middle reel, “Cherry-Bell-ANY” is controlled to be aligned on the winning line. The cherry 2 having such a configuration may be applied as a special prize.

  In this way, in the plurality of specific reels, symbols that are subject to winning determination are arranged beyond the draw range (the cherry on the left reel, the black 7 on the middle reel), and the symbols on the plurality of specific reels. Even when the cherry 2 that needs to be stopped at a timing that becomes the drawing range of the symbol to stop the symbol on the winning line is applied as a special prize, a plurality of specific reels, That is, at a higher rate than the reels that need to select the number of sliding frames other than 2 frames out of 0 to 4 frames in the maximum drawing range in order to draw the target symbol to the maximum within the maximum drawing range depending on the operation timing, By increasing the number of sliding frames that can perform stop control, the number of sliding frames that can be selected is selected, thereby increasing the chances of low-speed stop control. It can be.

  In addition, when applying weak cherries and strong cherries as described above, the ratio of strong cherries winning at the same time as special roles is higher than weak cherries, or it provides benefits that are advantageous to players. In this case, it is preferable that the strong cherry win is given preference over the weak cherry win, so that even if the cherry is the same, the player's expectation will be sharpened by the difference in the display mode. Can be put out.

  In the above-described embodiment, an example in which three reels 2L, 2C, and 2R are applied is described. However, only one reel is provided, and a prize is determined according to a display result of the one reel. Alternatively, two reels may be provided, and winning may be determined according to the combination of display results of the two reels, or four or more reels may be provided, and winning may be determined according to the combination of display results of these reels. May be determined.

  In the above-described embodiment, the slot machine to which medals are applied as a game medium used for setting the number of bets and giving game value associated with winning is described as an example. However, the slot machine that embodies the present invention may be a slot machine to which a game ball used in a pachinko gaming machine is applied as a game medium. When using a game ball as a game medium, for example, one medal can correspond to five game balls, and when 3 is set as the number of bets in the above embodiment, 15 game balls are used. This is equivalent to setting the number of bets using.

  In the above embodiment, the slot machine for setting bets using medals and credits is used. However, the present invention is not limited to this, and slots for setting bets using game balls are used. It may be a machine or a fully credit type slot machine that uses only credits to set bets.

  Further, in addition to the medal insertion mechanism such as the flow path switching solenoid 30 and the insertion medal sensor 31, a ball take-in device that takes in a game ball, and a take-in ball that detects a game ball taken in by the ball take-in device In addition to a medal payout mechanism, such as a hopper motor 34b and a payout sensor 34c, a ball payout device for paying out game balls, and a payout ball detection switch for detecting game balls paid out by the ball payout device It is possible to set a bet number using both medals and game balls and play a game, and the present invention may be applied to a slot machine in which medals and game balls are paid out by winning.

  Further, the slot machine of the present invention includes a variable display device capable of deriving and displaying a display result in each of a plurality of variable display areas capable of variably displaying a plurality of types of identification information each identifiable. The game can be started by setting a predetermined number of bets for one game using the utility value, and one game is completed by displaying the display result in all of the plurality of variable display areas. In addition, a winning can be generated according to a combination of display results derived and displayed in each of the plurality of variable display areas ”, but“ a plurality of types of identification information that can each be identified are variably displayed. Each of the variable display areas is provided with a variable display device capable of deriving and displaying a display result, and by using a gaming value, a predetermined number of bets are set for one game. The game can be started, and the display results are derived and displayed in all the variable display areas, thereby completing one game, and winning can be generated according to the combination of the display results derived and displayed in the variable display areas. It may be said.
