The CTC 508 resets the start time of the random number generated by the free run counter used for randomly determining the extension time (variable setting time) for extending the security time for each system reset or the random number circuit 509. A free-run counter or the like that is used to randomly determine each time may be included. Alternatively, these free-run counters may be included in an internal circuit of the main control unit 41 different from the CTC 508 such as a backup area of the RAM 507, for example.

  A random number circuit 509 included in the main control unit 41 is a circuit that generates numerical data that is a random value having a predetermined update range, such as a 16-bit random number. In the present embodiment, on the game control board 40 side, numerical data indicating a random value for internal lottery to be described later is controlled to be countable. In addition, in order to improve a game effect, random numbers other than these may be used.

  The ROM 506 provided in the main control unit 41 stores various selection data and table data used for controlling the progress of the game, in addition to the game control user program and the security check program 506A. For example, the ROM 506 stores data constituting a plurality of determination tables, determination tables, setting tables, and the like prepared for the CPU 505 to perform various determinations, determinations, and settings. The ROM 506 stores table data constituting a plurality of command tables used for the CPU 505 to transmit control signals serving as various control commands from the game control board 40.

  The RAM 507 provided in the main control unit 41 is provided with a game control data holding area 590 as an area for holding various data used for controlling the progress of the game in the slot machine 1. For example, a DRAM is used as the RAM 507, and a refresh operation is required to maintain the stored data contents. The CPU 505 has a built-in refresh register for performing this refresh operation. For example, the refresh register consists of 8 bits, and the lower 7 bits are automatically incremented each time the CPU 505 fetches an instruction from the ROM 506. Accordingly, the stored value in the refresh register is updated every execution time of one instruction in the CPU 505.

  The transmission shift register 562 is a register for storing command data converted into serial data. The command data stored at the earliest stage among the command data stored in the transmission data register 561 is converted into serial data. And stored in the transmission shift register 562. When the command data is stored in the transmission shift register 562, the command data is immediately transferred to the sub-control unit 91.

  The status register 563 stores data indicating the transmission state of the serial communication circuit 511, such as transmission completion indicating whether or not command data is being transmitted, and data empty indicating whether or not command data is stored in the transmission data register 561. Register. When “1” is stored as the value of transmission completion, it indicates that the command data has not been transmitted or the transmission of command data has been completed, and when “0” is stored, Indicates that command data is being transmitted or is waiting for command data transmission. When “1” is set as the data empty value, it indicates that one or more command data waiting for transmission is stored in the transmission data register 561, and when “0” is stored. The transmission data register 561 indicates that command data waiting for transmission is not stored.

  The value of the status register 563 can be referred to by the CPU 505 via the internal bus, and the CPU 505 can check the transmission state of the serial communication circuit 511 by reading the value of the status register 563.

  As shown in FIG. 7B, when the command data 1 and 2 are stored in the transmission data register 561 according to the transfer instruction of the CPU 505, both the transmission completion and data empty values change to “0”.

  Next, as shown in FIGS. 7C and 7D, the command data 1 stored first among the command data 1 and 2 stored in the transmission data register 561 is converted into serial data, and the transmission shift register 562 is converted. When the transmission of the command data 1 is completed, the next stored command data 2 is converted into serial data and transmitted to the sub control unit 91 by the transmission shift register 562. At the same time, the last command data is converted into serial data and stored in the transmission shift register 562. When the transmission data register 561 becomes empty, the value of the data empty changes to “1”, as shown in FIG. Thus, when the transmission of the last command data stored in the transmission shift register 562 is also completed, the transmission is completed. Value also changes to "1", a state in which transmission is completed for all the command data.

The sub control unit 91 detects a power failure at a later stage than the main control unit 41, and performs a power interruption process (sub) described later.

  Similar to the main control unit 41, the sub control unit 91 has an interrupt function, generates an interrupt when receiving a command from the main control unit 41, and acquires a command transmitted from the main control unit 41. Execute command reception interrupt processing to be stored in the buffer. Further, the sub control unit 91 executes an interrupt process (sub), which will be described later, by generating an interrupt every time the number of input system clocks reaches a certain number, that is, every certain interval.

  Also, unlike the main control unit 41, the sub control unit 91 interrupts the process even when the timer interrupt process (sub) is being executed when an interrupt is generated based on the reception of the command. The command reception interrupt process is executed at the same time, and the command reception interrupt process is executed with the highest priority even if interrupts that trigger the timer interrupt process (sub) occur at the same time.

  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 set value, the front door 1b is opened, and the power switch 39 and the setting key switch 37 of the power box 100 provided in the housing 1a are operated to turn on the power of the slot machine 1. In such a case, the slot machine 1 needs to be turned on 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 507 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 507 of the main control unit 41, and the state shifts to a state in which the game can proceed. Since the power switch 39 is temporarily turned off, the setting key switch 37 is turned on, and the power switch 39 is turned on to perform a transition to the setting change state, the operations are collectively referred to as a setting change operation. .

  In the present embodiment, since the setting change operation can be performed by opening the front door 1b, it can be said that the front door 1b is an opening / closing body. Moreover, it can be said that the door open detection switch 25 for detecting the open state of the front door 1b is an open / closed state detecting means.

  In order to check the set value, after the game is over, the setting key switch 37 may be turned on in a state where the bet amount is not set. When the setting key switch 37 is turned on in such a situation, the setting value read out from the RAM 507 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 setting 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, the main control unit 41 determines whether or not the voltage drop signal from the power interruption detection circuit 48 is detected every time the timer interruption process (main) is executed. If the determination process is performed and it is determined that the voltage drop signal is detected in the power failure determination process, the power interruption process (main) is executed. In the power interruption process (main), the register is saved in a stack of a RAM 507, which will be described later, and destructive diagnosis data (in this embodiment, 5AH) in which any bit is 1 is stored in the RAM 507, that is, specific data other than 0 is stored. In addition to the storage, the RAM parity adjustment data is calculated so that the RAM parity based on the data stored in all areas of the RAM 507 becomes 0 and stored in the RAM 507. The RAM parity is a value calculated as an exclusive OR of the values stored in each bit of the corresponding area (all areas in this embodiment) of the RAM 507. For this reason, if the RAM parity based on the data stored in all areas of the RAM 507 is 0, the RAM parity adjustment data is 0, and the RAM parity based on the data stored in all areas of the RAM 507 is 1. In this case, the RAM parity adjustment data is 1.

  The main control unit 41 calculates the RAM parity based on the data stored in all areas of the RAM 507 at the time of activation, regardless of whether the system reset or the user reset, and the value of the data for destructive diagnosis And the processing state of the main control unit 41 is restored to the state before the power interruption based on the data stored in the RAM 507 on the condition that the RAM parity is 0 and the value of the data for destruction diagnosis is also correct. However, if the RAM parity is not 0 (in the case of 1) or the value of the destruction diagnosis 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. However, the progress of the game is disabled. Unlike the normal error state, 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 above-described setting change state. It will not be released until

  In this embodiment, all data stored in the RAM 507 is held by the backup power source even in the event of a power failure, and the main control unit 41 determines that the data in the RAM 507 is normal when the power is turned on. In addition, the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 507. However, only the data stored in the RAM 507 that is necessary for returning to the control state in the event of a power failure is backed up and the power is turned on. It may be configured to return to the control state before power interruption based on the data backed up at the time.

  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.

  The sub control unit 91 also determines whether or not the voltage drop signal from the power interruption detection circuit 98 is detected in the timer interrupt process (sub), and if it is determined that the voltage drop signal is detected, Disconnection processing (sub) is executed. In the power interruption process (sub), the register is saved in a stack of a RAM 91c, which will be described later, and destructive diagnosis data in which any bit is 1 is stored in the RAM 91c, and also based on data stored in all areas of the RAM 91c. The RAM parity adjustment data is calculated so that the RAM parity becomes 0 and stored in the RAM 91c.

  Then, the sub-control unit 91 calculates the RAM parity based on the data stored in all the areas of the RAM 91c at the time of activation, and sets the data stored in the RAM 91c on the condition that the RAM parity is 0. Based on this, the processing state of the sub-control unit 91 is restored to the state before the power interruption, but when the RAM parity is not 0 (in the case of 1), it is determined that the RAM is abnormal and the RAM 91c is initialized. . In this case, unlike the main control unit 41, only the RAM 91c is initialized, and the performance is not disabled.

  In this embodiment, all data stored in the RAM 91c is held by the backup power supply even in the event of a power failure, and the sub-control unit 91 determines that the data in the RAM 91c is normal when the power is turned on. In addition, the configuration is such that the control state before power interruption is restored based on the data stored in the RAM 91c, but only the data required to return to the control state during a power failure is backed up among the data stored in the RAM 91c and the power is turned on. It may be configured to return to the control state before power interruption based on the data backed up at the time.

  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.

  Next, initialization of the RAM 507 of the main control unit 41 will be described. The storage area of the RAM 507 of the main control unit 41 is divided into an important work, a general work, a special work, a set value work, a non-saved work, a non-initialized area, an unused area, and a stack area.

  The important work is a work in which data which is inconvenient if it is initialized at the end of the BB, such as various display devices, LED display data, I / O input / output data, and game time counter. 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 such as various software random numbers that are initialized only before the setting is started. 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 507 is destroyed at the time of activation. The uninitialized work is a work that stores data that is not initialized even when a RAM error or setting is changed. The non-initialized work further includes a set value work for storing a set value used when a lottery is performed in the internal lottery process, and a command buffer (in the command buffer) in which a command transmitted to the effect control board 90 is temporarily stored. This command is maintained until the next command is stored, so the last transmitted command is always stored), so that the medal IN signal, medal OUT signal, and RB output to the external output board 1000 are stored. Of the medium signal, BB signal, door open signal, setting change signal, input error signal, and payout error signal, the door open signal, setting change signal, input error signal, and payout constituting the security signal output from the external output board 1000 A security work for storing the output state (on / off state) of the error signal is assigned. The unused area is an unused area in the storage area of the RAM 507, 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 control unit 41 is stored, and the unused stack area is one of a plurality of initialization conditions to be described later, like the unused area. However, if it is established, it will be initialized, but the in-use stack area is not initialized because the program continues.

  In this embodiment, the main control unit 41 stores the data in the RAM 507 when the setting key switch 37 is turned on, when a RAM error occurs, when the BB ends, and when the setting key switch 37 is turned off. When not being destroyed, when five initialization conditions at the end of one game are satisfied, four types of initializations that are initialized in accordance with each initialization condition are performed.

  Initialization 1 is an initialization performed when the setting key switch 37 is turned on at the time of startup and transitions to a setting change state, or initialization performed when a RAM abnormality error occurs. In the storage area of the RAM 507, all areas (including the unused area and the unused stack area) other than the used stack area and the non-initialized area are initialized. Initialization 2 is initialization performed at the end of the BB. In initialization 2, a general work, an unused area, and an unused stack area are initialized in the storage area of the RAM 507. Initialization 3 is an initialization performed when the setting key switch 37 is in an off state at the time of startup and the data in the RAM 507 is not destroyed. In the initialization 3, the unsaved work, the unused area, and the The used stack area is 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 507 are initialized.

  In this embodiment, initialization 1 is performed before the change of the setting change state. However, the initialization 1 is performed at the end of the setting change state, or both before the change of the setting change state and at the end of the setting change state. Also good.

  As described above, in this embodiment, when a RAM abnormality error occurs at the time of power-on or the like, initialization 1 is executed and the control state before that is initialized. The data stored in the command buffer, setting value work, and security work allocated to the data area is not initialized but is retained. At this time, the command buffer has the command sent last when the RAM abnormality error occurred, the set value work has the set value when the RAM abnormal error occurs, and the security work has the door when the RAM abnormal error occurs. Since the output status of the release signal, setting change signal, input error signal, and payout error signal is held in a stored state, whether any error command is transmitted from these data when a RAM error occurs, It is possible to specify whether the value has not been changed, the output state of the door open signal, setting change signal, input error signal, and payout error signal, and the cause of the RAM abnormality can be specified Furthermore, it is possible to identify the possibility that some kind of fraud has been performed.

  Furthermore, in order to eliminate the RAM abnormality error, the uninitialized area is not initialized even if the setting value is changed, and the stored data in the uninitialized area is intentionally initialized. Since it is impossible, even if a RAM abnormality error occurs due to fraud, the stored data of the command buffer, setting value work, and security work can be left as a trace.

  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, all the pay lines L1 to L5 are activated when a specified number of bets according to the gaming state are set.

  In the slot machine 1 of this embodiment, when all the reels 2L, 2C, 2R are stopped, the activated pay line (in the present embodiment, all the pay lines are always enabled. The activated winning line is simply referred to as a winning line), and a winning combination is obtained when a combination of symbols called “comb” is arranged. 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 to a game state advantageous to the player. Below, a small role and a re-playing role are collectively called a general role. In order to win each winning combination determined according to the game state, it is necessary to win an internal lottery described later and set a winning flag for the winning combination in the RAM 507.

  Of the winning flags for each of these combinations, the winning flag for the small role and the re-playing role is valid only in the game in which the flag is set, and is 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.

  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 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 value for internal lottery (an integer from 0 to 65535) is acquired when the start switch 7 is detected. Specifically, the value of the random number storage work assigned to the RAM 507 is set to the lottery work assigned to the RAM 507. Then, for each combination determined according to the gaming state and whether or not the special combination is carried over, numerical data stored in the lottery work, and determination of each combination determined according to the gaming state, the number of bets and the set value This is done according to the number of values.

  The random value storage work is a storage area for storing numerical data latched in the random value register R1D simultaneously with the operation of the start switch 7, and is latched every time new numerical data is latched in the random value register R1D. The numerical data is read in the subsequent timer interrupt process (main), and the numerical data stored in the random value storage work is updated to the latest latched numerical data.

  In the internal lottery, the number of judgment values determined in accordance with the internal lottery target, the current gaming state, and the set value are sequentially assigned to the random number for internal lottery (numerical data stored in the lottery work). When the result of addition overflows, it is determined that the winning combination is 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.

  If a winning combination of any combination is determined, a winning flag corresponding to the winning combination is set in the internal winning flag storage work assigned to the RAM 507. The internal winning flag storage work consists of a 2-byte storage area, of which the upper byte is assigned as the special role storing work in which the winning flag for the special role 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.

The main control unit 41, when the rotation of the reels is started, and the reel is stopped, and when there remains still rotating reel, with reference to the table index and data table created is stored in the ROM506 A stop control table is created for each reel that is rotating. When any of the stop switches 8L, 8C, and 8R corresponding to the rotating reel is effectively detected, the stop control table of the corresponding reel is referred to and the slip of the referred stop control table is referred to. Based on the number of frames, control is performed to stop the rotation of the reels 2L, 2C, 2R corresponding to the operated stop switches 8L, 8C, 8R.

  In the table index, an index that indicates the start address of the area in which the data for table creation is stored, from the reference address when referring to the table index, according to the setting state of the winning flag by internal lottery (hereinafter referred to as the internal winning state) Differences up to the address where the data is stored are registered. As a result, a difference corresponding to the internal winning state is acquired, and the corresponding index data can be acquired by adding the difference to the reference address. Even when the winning combinations are different, when the same control is applied, the same address is stored as the index data. In such a case, the same table creation data is referred to. Thus, a stop control table is created.

  The table creation data includes a stop control table indicating the number of sliding frames according to the stop operation position, and an address of the stop control table to be referred to according to the reel stop status.

  The stop control table referred to according to the reel stop status is whether all reels are rotating, only the left reel is stopped, only the middle reel is stopped, only the right reel is stopped, It may vary depending on whether the middle reel is stopped, the left and right reels are stopped, the middle and right reels are stopped, and if any reel is stopped, stop Since there may be differences depending on the stop position of the reels already completed, the address of the stop control table to be referenced for each situation is registered for each rotating reel, and based on the top address of the table creation data, It is possible to specify the address of the stop control table that should be referred to according to the status of each, and it is necessary according to each status from this specified address. And to be able to identify the stop control table. Even when the reel stop status and the stopped position of the stopped reel are different, when the same stop control table is applied, the same address may be registered as the address of the stop control table. In such a case, the same stop control table is referred to.

  The stop control table 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 336 steps, the reels 2L, 2C, and 2R make one round. Then, 21 areas (frames) divided every 16 steps (the number of steps that one symbol moves) are defined for one reel, and these areas are areas 0 to 20 from the reel reference position. A number is assigned. 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 stop control table, the number of sliding symbols for each area number is compressed and stored according to a predetermined rule, and the number of sliding symbols for each area number can be acquired by expanding the stop control table. Yes.

  As described above, the stop control table created by referring to the table index and the table creation data corresponds to the area number, and the area corresponding to each area number is the stop reference position (in this embodiment, the perspective window 3). Sliding frame when an operation of the stop switches 8L, 8C, 8R is detected at a timing (a timing in which the number of steps from the reel reference position is included in the range of the number of steps of each region number). It is a table with each number set.

  Next, the procedure for creating the stop control table will be described. First, at the start of reel rotation, the top address of the table creation data corresponding to the internal winning state of the game is acquired. Specifically, the table index is first referred to, index data corresponding to the internal winning state is obtained, table creation data is identified based on the obtained index data, and all reels are identified from the identified table creation data. The address of the stop control table for each reel corresponding to the state of rotation is acquired, and the stop control table for each reel stored at the acquired address is expanded to generate a stop control table for all reels.

  Further, when any one reel stops or any two reels stop, the index data acquired at the start of reel rotation, that is, the top address of the table creation data corresponding to the internal winning state of the game The table creation data is identified based on the table creation data, and the stop control table address of the unreacted reel corresponding to the stopped reel and the area number of the stop position of the reel is obtained from the identified table creation data. The stop control table for each stored reel is expanded to create a stop control table for the unstopped reels.

  Next, when the main control unit 41 effectively detects any one of the stop switches 8L, 8C, and 8R corresponding to the rotating reel, the control when the display result is derived to the corresponding reel is described. To explain, when any operation corresponding to the rotating reel is detected effectively among the stop switches 8L, 8C, 8R, the stop operation position is based on the number of steps from the reel reference position when the stop operation is detected. The number of sliding symbols corresponding to the area number of the specified stop operation position is acquired by referring to the stop control table of the reel where the stop operation is detected. Then, control is performed to rotate and stop the reel by the number of acquired sliding frames. 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 to the stop is calculated, and the reel is rotated and stopped by the calculated number of steps. Take control. As a result, the area corresponding to the area number that is the stop position ahead of the number of sliding frames from the area corresponding to the area number of the stop operation position where the stop operation is detected is the stop reference position (in this embodiment, the perspective window 3 It will stop in the lower symbol area).

  In the table index of this embodiment, only one address is stored as index data corresponding to one internal winning state in one gaming state, and further, one table creation data includes one reel. Only one address is stored as the address of the storage area of the stop control table corresponding to the stop status (and the stop position of the stopped reel). In other words, table creation data corresponding to one internal winning state in one gaming state and stop control tables corresponding to reel stop states (and stopped positions of stopped reels) are uniquely determined. The stop control table created with reference to is unique for one internal winning state in one gaming state and the reel stop status (and the stop position of the stopped reel). Therefore, when all of the gaming state, the internal winning state, and the reel stop status (and the stop position of the stopped reel) are the same, the reel is based on the same stop control table, that is, the same control pattern. The stop control is performed.

Further, in this embodiment, has a value of 0-4 is defined as the number of sliding frames, it is possible to stop the reel draws up 4 FIG pattern from the detection of the stop operation. In other words, the stop position of the symbol can be designated from a range of up to 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 this embodiment, when any of the winning combinations is won, the winning combination is drawn to the maximum in the range of 4 frames on the winning line, and the non-winning winning combination is drawn so that it is not aligned on the winning line. A stop control table with a defined number of frames is created and reel stop control is performed. If no winning combination is selected, a stop control table with a determined number of sliding symbols that do not have any combination And stop control of the reel. As a result, when a stop operation is performed, if the winning combination can be stopped on the winning line in the drawing range of up to 4 frames, the control is performed so that the winning combination is stopped. The combination that has not been performed will be controlled to be stopped in a drawing range of a maximum of 4 frames.

  When a special role and a small role are elected at the same time, such as when a special role is elected while the special role has been carried over from before the previous game, the winning small role is the maximum in the range of 4 frames on the winning line. The number of sliding frames is fixed so that it can be drawn to the limit, and for the stop operation position where the selected small role cannot be drawn in the range of up to 4 frames in the winning line, the winning special role is in the range of 4 frames in the winning line Then, a stop control table in which the number of sliding frames is determined so as to be pulled in as much as possible is created, and reel stop control is performed. As a result, when a stop operation is performed, if it is possible to stop all the small roles that have been elected in the drawing range of up to four frames on the winning line, the control is performed so that the winning combination is stopped. If you can't draw a small role that has been won in the drawing range of up to 4 frames on the line, if you can stop with a special role that has been won in the drawing range of up to 4 frames on the winning line, A control is performed to stop them in a uniform manner, and a winning combination that has not been won will be controlled to be stopped within a 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 won only when the small combination cannot be drawn. When a special combination and a small combination can be withdrawn at the same time, only the small combination is drawn in, and the small combination is not aligned on the winning line at the same time as the special combination.

  In this example, when a special role is elected while the special role has been carried over from before the previous game, or when a special role and a small role are simultaneously elected, the special role and the small role are won simultaneously. If the selected special role is given priority over the selected special role, the special role is controlled on the winning line only when the small role cannot be withdrawn. When winning simultaneously, priority is given to the control for aligning the special role on the winning line over the small role, and the control for aligning the small role on the winning line may be performed only when the special role cannot be drawn.

  If a special player and a replaying player are elected at the same time, such as when a replaying player is elected while the special role has been carried over from before the previous game, when the stop operation is performed, In addition, a control is performed in which the symbols of the re-gamer are aligned and stopped within a drawing range of up to 4 frames. In this case, the symbols constituting the re-gamer or the symbols constituting the re-gamer to be simultaneously elected are arranged at intervals of 5 symbols or less, that is, within 4 frames, for any of the reels 2L, 2C, and 2R. Since it can always be stopped at any position within the 4-frame pull-in range, if the special combination and the re-playing combination are elected at the same time, the timing of the operation of the stop switches 8L, 8C, 8R by the player Without fail, the re-playing role will always be won. 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 the case where the special combination and the re-playing combination can be withdrawn at the same time, only the re-playing combination is drawn in, and the special combination is not arranged on the winning line at the same time as the re-playing combination.

  In this embodiment, after the rotation of the reels 2L, 2C, and 2R is started, the main control unit 41 rotates the reels for which the stop operation has not been detected yet until the operation of the stop switches 8L, 8C, and 8R is detected. Continuously, 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.

  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, various control contents executed by the main control unit 41 in the present embodiment will be described below with reference to FIGS.

  When the system reset signal is input from the reset circuit 49, the main control unit 41 performs the startup process (main) shown in the flowchart of FIG. When a user reset signal is input, the process starts from the step Sa2 of the startup process (main). That is, while starting from the security mode in which the security check process is performed only in the case of activation upon power-on, the user program stored in the ROM 506 is executed by omitting the security check process in the case of activation due to time-up of the watchdog timer. The user mode is started.

  In the startup process (main) accompanying the input of the system reset signal, first, the CPU 505 executes the security check process based on the security check program 506A read from the ROM 506 (Sa1). At this time, the main control unit 41 enters the security mode, and the game control user program stored in the ROM 506 is not yet executed.

  After the security check process in step Sa1, the operation state of the main control unit 41 shifts from the security mode to the user mode, and the execution of the user program stored in the ROM 506 is started. As described above, at the time of start-up accompanying the input of the user reset signal, the user mode is started without going through the security mode.

  In the user mode, first, built-in devices such as the serial communication circuit 511, peripheral IC, interrupt mode, stack pointer, etc. are initialized (Sa2), and then the values of the I register and IY register are initialized (Sa3). By initialization of the I register and the IY register, an interrupt table address to be referred to when an interrupt occurs is set in the I register, and a reference address for referring to the storage area of the RAM 507 is set in the IY register. . These values are fixed values and are always initialized at startup.

Next, access to the RAM 507 is permitted (Sa4), and RAM parities of all storage areas (including unused areas and unused stack areas) of the RAM 507 are calculated (Sa5). Next, the states of the stop switch 36 a and the automatic checkout switch 36 b are acquired, and after setting the stop function and the automatic checkout function to valid / invalid in a specific register of the main control unit 41 (Sa6) , the port input described later The input data of each switch acquired in the process, the confirmation data of each switch indicating that the previous and current input data are in the same state, and the edge data of each switch indicating that the previous and current determined data are different are each cleared (Sa7). Further, the power interruption flag indicating that a power failure has been detected is cleared (Sa8). Further, the value of the door monitoring timer for measuring the monitoring interval of the detection state of the door opening detection switch 25 and the history of the input state of the detection signal from the door opening detection switch 25 are cleared (Sa9), the operation detection command transmission request and the door are cleared. The command transmission request 2 is cleared and the door command transmission request 1 is set (Sa10).

  Next, it is determined whether or not the RAM parity calculated in step Sa5 is 0 (Sa13). If the power interruption interrupt processing (main) is normally performed, the RAM parity should be 0. If the RAM parity is not 0 in the step of Sa13, the data stored in the RAM 507 is not normal. In this case, after executing the initialization 1 for initializing all the storage areas except the used stack area and the non-initialization area among the storage areas of the RAM 507 (Sa26), is the setting key switch 37 turned on? If the setting key switch 37 is on, the detection state of the door opening detection switch 25 is acquired, and the front door 1b is in the open state based on the detection state of the door opening detection switch 25. It is determined whether or not (Sa32).

  If it is determined in step Sa32 that the front door 1b is in the open state, a setting command indicating the start of setting is generated and stored in the command buffer (Sa23), and the command stored in the command buffer is stored in the serial communication circuit 511. The command storage process to be transferred to the transmission data register 561 is performed (Sa24), the interrupt is permitted (Sa25), and the setting change process, that is, the setting change state is entered.

  In the command storage process of Sa24, as shown in FIG. 9A, the first byte of the command data stored in the command buffer is transferred to the transmission data register 561 (Sx1), and then stored in the command buffer. The second byte of the stored command data is transferred to the transmission data register 561 (Sx2). The command data transferred to the transmission data register 561 is converted into serial data in the order of transfer to the transmission data register 561 as described above, stored in the transmission shift register 562, and transmitted to the sub-control unit 91. Will be.

  On the other hand, if it is determined in step Sa32 that the front door 1b is not open, an error code indicating an abnormal setting operation is set in the register (Sa33), and an error command indicating the abnormal setting operation is generated to generate a command buffer. (Sa34), the command storage process is performed, the error command in the command buffer is transferred to the transmission data register 561 (Sa30), the interrupt is permitted (Sa31), and the error process, that is, the error setting operation error state Migrate to

  If the setting key switch 37 is off in step Sa27, an error code indicating RAM abnormality is set in the register (Sa28), an error command indicating RAM abnormality is generated and stored in the command buffer (Sa29), and the command is stored. Processing is performed to transfer the error command in the command buffer to the transmission data register 561 (Sa30), interrupt is permitted (Sa31), and the process proceeds to error processing, that is, a RAM abnormal error state.

  If the RAM parity is 0 in step Sa13, it is further determined whether or not the destructive diagnosis data is normal (Sa14). If the power interruption processing (main) is normally performed, the data for destruction diagnosis should be set. If the data for failure diagnosis is not normal in step Sa14 (the data for destruction diagnosis is stored at the time of power interruption) In the case other than 5A (H), the data in the RAM 507 is not normal. Therefore, the process proceeds to step Sa26 and initialization 1 is executed, and then the setting key switch 37 is turned on in step Sa27. For example, it is determined whether or not the front door 1b is in an open state (Sa32), and when it is determined that the front door 1b is in an open state, a setting command is generated to indicate setting start (Sa23), and command storage processing is performed. After (Sa24), when interrupt is permitted (Sa25), the process proceeds to the setting change process, and it is determined in step Sa32 that the front door 1b is not in the open state. Then, an error code indicating an abnormal setting operation is set in the register (Sa33), an error command indicating the abnormal setting operation is generated (Sa34), and after the command storing process (Sa30), an interrupt is permitted (Sa31) Transition to processing. If the setting key switch 37 is off in step Sa27, an error code indicating a RAM abnormality is set (Sa28), an error command indicating a RAM abnormality is generated (Sa29), and a command storing process (Sa30) is performed. Is permitted (Sa31), and the process proceeds to error processing.

  If it is determined in step Sa14 that the destructive diagnosis data is normal, the data in the RAM 507 is normal. Therefore, the destructive diagnosis data is cleared (Sa15), and the unstored work, the unused area, and the unused area in the RAM 507 are cleared. After initialization 3 for initializing the used stack area (Sa16), it is determined whether or not the setting key switch 37 is on (Sa17). If the setting key switch 37 is on, the process proceeds to step Sa22. Initialization 1 is executed to determine whether or not the front door 1b is in an open state (Sa32). If it is determined that the front door 1b is in an open state, a setting command indicating the start of setting is generated ( Sa23) After the command storage process (Sa24), the interrupt is permitted (Sa25), the process proceeds to the setting change process, and the front door 1b is opened in the step of Sa32. If it is determined that it is not, an error code indicating the abnormality setting operation is set in the register (Sa33), an error command indicating the abnormality setting operation is generated (Sa34), and an interrupt is issued after the command storing process (Sa30). Permit (Sa31), and shift to error processing.

If the setting key switch 37 is OFF in the step of Sa17, each register is restored to the state before power interruption, that is, the state saved in the stack (Sa18), and a return command is generated and stored in the command buffer ( Sa19) The command storage process is performed, the return command in the command buffer is transferred to the transmission data register 561 (Sa20), the interrupt is permitted ( Sa21), and the process that was executed last before the power interruption is returned. .

  FIG. 10 is a flowchart showing the control contents of error processing executed by the main control unit 41.

  In the error processing, first, the current display state of the game auxiliary display 12 is saved in the stack (Sb1), the error code stored in the register is displayed on the game auxiliary display 12 (Sb2), and the error code is stored in the RAM. It is determined whether the error is an abnormal error or an abnormal setting operation error (Sb3). If the error code indicates a RAM abnormal error or an abnormal setting operation error, the process proceeds to a loop process that does not perform any process.

  When it is determined in step Sb3 that neither the error code indicating the RAM error error nor the error setting operation error is generated, an error command indicating the occurrence of the error state and its type is generated and stored in the command buffer (Sb4). A command storage process is performed to transfer the error command in the command buffer to the transmission data register 561 (Sb5).

  Next, it is determined whether or not an on change is detected from the reset / setting switch 38 off (Sb6). If no on change is detected from the reset / setting switch 38 off, the reset switch 23 is further turned off. It is determined whether or not a change in on is detected (Sb7). If no change in on is detected from off of the reset switch 23, the process returns to step Sb6. That is, the game waits in a state where the progress of the game is impossible until a change of on from the off of the reset / setting switch 38 or the reset switch 23 is detected.

  If a change from on to off of the reset / setting switch 38 is detected in step Sb6 or a change from on to off from the reset switch 23 is detected in step Sb7, the switch detection state is changed. Edge data indicating that it has changed from off to on or that it has changed from on to off (referred to as a rising edge when it changes from off to on, and a falling edge when it changes from on to off) Clear (Sb8), clear the error code stored in the register (Sb9), return the display state of the auxiliary game display 12 to the display state saved in the stack in the step of Sb1 (Sb10), An error command indicating the cancellation is generated and stored in the command buffer (Sb11 , After transferring an error command in the command buffer to the transmit data register 561 performs command storage processing (Sb12), it returns to the original processing.

  FIG. 11 is a flowchart showing the control content of the setting change process executed by the main control unit 41.

  In the setting change process, first, the setting value stored in the setting value work of the RAM 507 is read out, and the read value is set as the display value (Sc1). (Sc2), if the display value is within the settable range, the process proceeds to step Sc4. If the display value is outside the settable range, the display value is corrected to 1, and the process proceeds to step Sc5.

  In the step of Sc5, after the display value is displayed on the setting value display 24, the reset / setting switch 38 and the start switch 7 are turned off to wait for detection of an on change (Sc5, Sc6). When a change from on to off of the reset / setting switch 38 is detected, the edge data is cleared (Sc9), the display value is incremented by 1 (Sc10), and the process returns to the step Sc2.

  Further, when a change from on to off of the start switch 7 is detected in the step of Sc6, the edge data is cleared (Sc9), and the other switches are turned on by referring to finalized data to be described later. (Sc10), if any switch is in the on state, the process returns to the step of Sc5, and if any switch is not in the on state, the value displayed on the set value display 24 is set to 0. (Sc11), and waits until the setting key switch 37 is turned off (Sc12).

  When the setting key switch 37 is turned off in the step of Sc11, the display value is stored in the setting value work (Sc13), and the setting command indicating the end of setting and the new setting value is generated and stored in the command buffer. (Sc14), a command storing process is performed, the setting command in the command buffer is transferred to the transmission data register 561 (Sc15), and the process proceeds to the game process.

  FIG. 12 is a flowchart showing the control contents of the game process executed by the main control unit 41.

  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 a bet number can be set, and a process for starting a game when a specified number of bets is set according to the gaming state and the start switch 7 is operated is executed. .

  In the internal lottery process in the step of Sd2, it is determined whether or not the above winning combination is allowed based on the internal lottery random value latched simultaneously with the start of the game by the detection of the start switch 7 in the step of Sd1. Process. In this internal lottery process, a winning flag is set in the RAM 507 based on each lottery result.

  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 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.

  In the game process, a command is generated in accordance with the progress control of the game, set in the command buffer, and immediately after executing the command storage process, the command stored in the command buffer is transmitted to the transmission data register of the serial communication circuit 511. 561 and transmitted to the sub-control unit 91.

  13 to 15 are flowcharts showing the control content of the BET process executed by the main control unit 41 in step Sd1.

  In the BET process, first, the value of the BET counter in which the value of the betting number is stored in the RAM 507 is cleared (Se1), a specified number corresponding to the gaming state is set in the RAM 507 (Se2), and the RAM 507 is a replay game. Whether or not the game is a replay game is determined on the basis of whether or not the replay game flag indicating is set (Se3).

  If it is determined in step Se3 that the game is a replay game, a BET command indicating that 3 bets have been added is generated and stored in the command buffer (Se4), and command storage processing is performed. The BET command in the command buffer is transferred to the transmission data register 561 (Se5), the value of the BET counter is incremented by 1 (Se6), the specified number of bets set in the RAM 507 is referred, and the value of the BET counter is specified. It is determined whether or not the number is a bet, that is, whether or not the number of bets serving as a game start condition is set (Se7), and if the BET counter value is not a specified number, the process returns to the step of Se6, and the value of the BET counter If is a prescribed number, the insertion prohibition flag indicating that the medal cannot be inserted is set in the RAM 507 (Se8), and the process proceeds to Step Se10.

  If it is determined in step Se3 that the game is not a replay game, settings before waiting to be made are performed (Se9), and the process proceeds to step Se10. In the setting before waiting for insertion, the insertion disable flag set in the RAM 507 is cleared, and a medal can be inserted.

  In the step of Se10, it is determined whether or not an error code is set in the register, that is, whether or not an error is detected. If an error code is set, the process proceeds to error processing shown in FIG.

  If no error code is set in the step of Se10, it is determined whether or not a medal can be inserted based on whether or not the insertion prohibition flag is set in the RAM 507 (Se11). When it is determined in step Se11 that the medal can be inserted, the flow path switching solenoid 30 is turned on, and the medal can be inserted using the medal flow path as a path on the hopper tank side. (Se12), the process proceeds to step Se14, and if it is determined that the medal cannot be inserted, the flow path switching solenoid 30 is set to the off state, and the medal flow path is the path on the medal payout exit 9 side. As a result, the insertion of a new medal is prohibited (Se13), and the process proceeds to the step Se14.

  In the step of Se14, it is determined whether or not the setting key switch 37 is on. If the setting key switch 37 is on, it is determined whether or not the value of the BET counter is 0 (Se15). If the value of the BET counter is 0 in step Se15, a setting confirmation command indicating the start of setting confirmation is generated and stored in the command buffer (Se16). Is transferred to the transmission data register 561 (Se17), and the setting confirmation process (Se18), that is, the setting confirmation state is entered. After the setting confirmation process in the step Se18 is completed, the process returns to the step Se10.

  If the setting key switch 37 is not on in step Se14 or if the value of the BET counter is not 0 in step Se15, the process proceeds to step Se19, and whether or not the inserted medal sensor 31 has detected passage of the inserted medal. That is, it is determined whether or not there is a inserted medal flag indicating that the passage of the inserted medal is detected. If the passage of the inserted medal is not detected in the step of Se19, the process proceeds to the step of Se31, and if the passage of the inserted medal is detected, the inserted medal flag is cleared (Se20), and the non-insertable flag is set in the RAM 507. Whether or not a medal can be inserted is determined based on whether or not a medal can be inserted (Se21). If the medal cannot be inserted, the process proceeds to Step Se31.

  If the medal can be inserted in the step of Se21, the prescribed number of bets set in the RAM 507 is referred to determine whether or not the value of the BET counter is the prescribed number (Se22), If the value is not the specified number, the value of the BET counter is incremented by 1 (Se23), a BET command indicating that the bet number is incremented by 1 is generated and stored in the command buffer (Se24), and command storage processing is performed. The BET command in the command buffer is transferred to the transmission data register 561 (Se25), and the process returns to the Se9 step.

  If the value of the BET counter is the prescribed number in the step of Se22, the credit counter value in which the credit value is stored in the RAM 507 is incremented by 1 (Se26), and a credit command indicating the current credit counter value is generated. The command is stored in the command buffer (Se27), the command storage process is performed, the credit command in the command buffer is transferred to the transmission data register 561 (Se28), and it is determined whether the value of the credit counter is 50 which is the upper limit value. If the value of the credit counter is not 50, the process returns to the step of Se9. If the value of the credit counter is 50, the insertion disable flag is set in the RAM 507 (Se30), and the process returns to the step of Se9.

  In step Se31, it is determined whether or not a change from on to off of the start switch 7 is detected, that is, whether or not a rising edge indicating a rising edge of the start switch 7 is set.

  If it is determined in step Se31 that no change from on to off of the start switch 7 has been detected, the process proceeds to step Se41, and if a change from on to off in the start switch 7 is detected, an interrupt will occur. Is prohibited (Se32), the edge data is cleared (Se33), and it is determined whether or not another switch is on based on finalized data described later (Se34). If interrupt is permitted (Se35), the process returns to the step of Se9.

  If none of the other switches are in the on state in step Se34, the bet number that is set in the RAM 507 is further referred to and the BET counter value is the specified number, that is, a bet that becomes a game start condition. It is determined whether or not the number is set (Se36).

  If the value of the BET counter is not the specified number in the step of Se36, the interrupt is permitted (Se35), and the process returns to the step of Se9. If the value of the BET counter is the specified number, the value of the random number storage work is internally stored. A random value for lottery is set in a lottery work (Se37), interrupt is permitted (Se38), an unloadable flag is set in the RAM 507, the flow path switching solenoid 30 is turned off, and the flow path of the medal Is set to be set at the start of the game (Se40). Then, after the step of Se40, the BET process is terminated and the process returns to the flowchart of FIG.

  After the change of the start switch 7 from off to on is detected in this way, it is determined that the operation of the start switch 7 is invalid or valid, and the value of the random value storage work is set as the lottery work. In the meantime, interrupts are prohibited and timer interrupt processing (main) is executed during this period to prevent rewriting of the random value storage work value. .

  In the step of Se41, it is determined whether or not a change from on to off of the single BET switch 5 is detected, that is, whether or not a rising edge indicating the rising of the single BET switch 5 is set. If a change of on from the off of the single BET switch 5 is not detected in the step of Se41, the process proceeds to a step of Se49, and if the change of on from the off of the single BET switch 5 is detected, the edge data is cleared. (Se42) With reference to the prescribed number of bets set in the RAM 507, it is determined whether or not the value of the BET counter is the prescribed number (Se43). If the value of the BET counter is the specified number in the step of Se46, the process returns to the step of Se9. If the value of the BET counter is not the specified number, it is determined whether or not the value of the credit counter is 0 (Se44). If the counter value is 0, the process returns to step Se9. If the value of the credit counter is not 0 in the step of Se47, 1 is subtracted from the value of the credit counter (Se45), 1 is added to the value of the BET counter (Se46), and BET indicating that 1 is added to the bet number A command is generated and stored in the command buffer (Se47), command storage processing is performed, the BET command in the command buffer is transferred to the transmission data register 561 (Se48), and the process returns to Se9.

  In step Se49, it is determined whether or not a change from on to off of the MAXBET switch 6 is detected, that is, whether or not a rising edge indicating the rising of the MAXBET switch 6 is set. If a change of on from the off of the MAXBET switch 6 is not detected in the step of Se49, the process proceeds to a step of Se58, and if a change of on from the off of the MAXBET switch 6 is detected, the edge data is cleared (Se50). Referring to the prescribed number of bets set in the RAM 507, it is determined whether or not the value of the BET counter is the prescribed number (Se51). If the value of the BET counter is the specified number in the step of Se51, the process proceeds to the step of Se55, and if the value of the BET counter is not the specified number, it is determined whether or not the value of the credit counter is 0 (Se52). If the value of the credit counter is 0, the process proceeds to step Se55. If the value of the credit counter is not 0 in the step of Se52, 1 is subtracted from the value of the credit counter (Se53), 1 is added to the value of the BET counter (Se54), and the process returns to the step of Se51. In the step of Se55, it is determined whether or not the BET counter has been added. If the BET counter has not been added, the process returns to the step of Se9, and if the BET counter has been added, the bet number is added by the added number. A BET command indicating this is generated and stored in the command buffer (Se56), command storage processing is performed, the BET command in the command buffer is transferred to the transmission data register 561 (Se57), and the process returns to the Se9 step.

In the step of Se58, it is determined whether or not a change from on to off of the settlement switch 10 is detected, that is, whether or not a rising edge indicating the rise of the settlement switch 10 is set. If the change of on from the off of the settlement switch 10 is not detected in the step of Se58, the process returns to the step of Se9, and if the change of on from the off of the settlement switch 10 is detected, the edge data is cleared (Se59). Then, based on whether or not the replay game flag is set in the RAM 507, it is determined whether or not the game is a replay game (Se60), and if the game is a replay game, the process returns to Se9. If the game is not a replay game in the step of Se60, it is determined whether or not the value of the BET counter is 0 (Se61). If the value of the BET counter is 0, the process proceeds to the step of Se63, and the value of the BET counter is 0. Otherwise, a bet amount settlement flag indicating that the already set bet amount is to be settled is set in the RAM 507 (Se62), and the process proceeds to Step Se63. In Se63 step, they were used in the hopper motor 34 b drives the pay out the credit counter or medals value amount stored in the BET counter control, that medals or betting amount set is stored as a credit medal Settlement process is performed in which the control to return is performed. Then, after the settlement process in the step of Se63, the input impossible flag set in the RAM 507 is cleared (Se64), and the process returns to the step of Se9.

  16 and 17 are flowcharts showing the control contents of the reel rotation process executed by the main control unit 41 in step Sd3.

  In the reel rotation process, first, a freeze lottery is executed (Si1). In the freeze lottery, whether to control the freeze state based on the result of the internal lottery or the like is determined, and in the case of controlling to the freeze state, the execution time is determined.

  After the freeze lottery in the Si1 step, it is determined whether or not a wait time (approximately 4.1 seconds in this embodiment) has elapsed since the reel rotation start time of the previous game (Si2), and the wait time has elapsed. If not, wait until the wait time elapses.

  If the wait time has elapsed in the Si2 step, a new wait time is set (Si3).

  Next, the reel motor is set to start rotating, and the reel starts rotating (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 the constant speed rotation of the reel is detected in the origin interruption process of the timer interrupt process (main). .

  Next, it is determined whether or not the freeze condition is satisfied, that is, whether it is time to control the freeze state in the freeze lottery (Si7), and the freeze condition is satisfied. If not, the process proceeds to step Si9. If the freeze condition is satisfied, a prescribed value is set in the freeze timer counter assigned to the RAM 507 to measure the time of the freeze state (Si8), and the process proceeds to step Si9. . The value of the freeze timer counter is decremented by 1 every time the timer interrupt process (main) is executed four times.

  In step Si9, it is determined whether or not the value of the freeze timer counter is 0, that is, whether or not the freeze timer is controlled. When the value of the freeze timer counter is not 0 in the step of Si9, that is, when it is controlled to the freeze state, the process waits until the value of the freeze timer counter becomes 0.

  When the value of the freeze timer counter is 0 in the step of Si9, that is, when the freeze state is not controlled (when the freeze state is not controlled from the beginning, or when the freeze state ends), either stop It is determined whether or not a change from on to off of the switch is detected, that is, whether or not a rising edge indicating a rising edge of any stop switch is set (Si10), and a change from off to on of any stop switch is changed. If no reel rotation error is detected, it is determined whether or not a reel rotation error (error determined when the reel reference position is not detected by the reel sensor 33 for a certain period or more) has occurred (Si11), and a reel rotation error occurs. If not, then there will be an insertion error Whether or not a medal insertion is detected, and whether or not a payout error (medal payout is detected in a period other than the period during which medal payout is permitted) is determined. ) Has occurred (Si12, Si13), and if no error is determined in the steps Si11 to Si13, the process returns to the step Si9.

  If it is determined that an insertion error has occurred in the Si12 step, or if a dispensing error is determined in the Si13 step, an error code indicating a loading / dispensing error during reel rotation is set in the register (Si14). ), And shifts to the error processing shown in FIG. 10 (Si17). When the error is released, the process returns to the Si9 step again.

  If it is determined in step Si11 that a reel rotation error has occurred, an error code indicating a reel rotation error is set in the register (Si16), and the process proceeds to error processing shown in FIG. 10 (Si17). 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.

  Further, when a change of on is detected from the off of one of the stop switches in the step of Si10, the edge data is cleared (Si18), and it is determined whether or not the other switch is on (Si19). If there is at least one other switch, the process returns to the step of Si10.

  If all the other switches are in the off state in the step of Si19, the number of steps from the reel reference position at that time in the reel motor corresponding to the stop switch in which the change from off to on is detected (becomes the stop operation position). Step number) is obtained and set to the work corresponding to the stop reel (Si20), a reel stop command is generated and stored in the command buffer (Si21), command storage processing is performed, and the BET command in the command buffer is The data is transferred to the transmission data register 561 (Si22) and waits until the reel rotation corresponding to the stop operation stops (Si23).

  When the rotation of the reels corresponding to the stop operation stops, it is determined whether or not all the reels have stopped (Si24). If all the reels have 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.

  FIGS. 18 and 19 are flowcharts showing the control contents of the timer interrupt process (main) executed by the main control unit 41 by interrupting and executing the activation process and the game process at regular intervals (0.56 ms interval). Note that other interrupts are automatically prohibited during the execution period of the timer interrupt process (main).

  In the timer interrupt process (main), first, after saving the register in use to the stack area (Sk1), the transmission completion value of the status register 563 of the serial communication circuit 511 is acquired, and based on the acquired value. The transmission completion flag stored in the RAM 507 is updated (Sk2). Specifically, if the value of the status register 563 is 1 indicating that command data transmission has not been performed or that command data transmission has been completed, the value of the transmission completion flag is updated to 1, and the status register 563 If the value is 0 indicating that a command is being transmitted or a command is waiting to be transmitted, the value of the transmission completion flag is updated to 0.

  Next, a power failure determination process is performed (Sk3). In the power failure determination process, it is determined whether or not a voltage drop signal is input from the power failure detection circuit 48. If a voltage drop signal is input, whether or not the voltage drop signal is input in the previous power failure determination process as well. If a voltage drop signal has been input in the previous power failure determination process, it is determined that a power failure has occurred, and a power interruption flag indicating that is set.

  After the power failure determination process in the step of Sk3, it is determined whether or not the power interruption flag is set (Sk4). If the power interruption flag is not set, the process proceeds to Sk5 and the power interruption flag is set The process proceeds to a power interruption process (main) described later.

  In step Sk5, port input processing for inputting detection data of various switches from the input port is performed.

  Next, the branch counter for identifying the timer interrupt to be executed in the timer interrupt process (main) is advanced by 1 from the four types of timer interrupts 1 to 4 (Sk6). In the step of Sk6, 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 (main) is executed.

  Next, referring to the counter value for branching, it is determined whether it is 2 or 3, ie, timer interrupt 3 or timer interrupt 4 (Sk7), 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 Sk11 described later and the phase signal data changed in the final stop process of Sk24 described later is executed (Sk8).

  Next, referring to the counter value for branching, it is determined whether or not it is 1, that is, timer interrupt 2 (Sk9). If it is not timer interrupt 2, that is, timer interrupt 1, reel motor Reel starting process (Sk10) for controlling the step time interval when starting 32L, 32C, 32R, motor step process (Sk11) for changing phase signal data of the reel motors 32L, 32C, 32R, reel motors 32L, 32C After the stop of 32R, motor phase signal standby processing (Sk12) for changing the phase signal to one-phase excitation after a certain time has been sequentially executed, and then the process proceeds to step Sk26.

  In the case of timer interrupt 2 in the step of Sk9, LED dynamic display processing (Sk13) for dynamically lighting various indicators, and output processing of control signals and the like for outputting data such as lighting signals of various LEDs to the output port (Sk14), a time counter update process (Sk15) for updating various time counters, a door monitoring process (Sk16) for monitoring the detection state of the door opening detection switch 25, a door command transmission request, etc., a door command and an operation detection command The command transmission process (Sk17) for performing transfer to the serial communication circuit 511 and the like and the external output signal update process (Sk18) for updating the external output signal are sequentially executed, and then the process proceeds to step Sk26.

  If the timer interrupt 3 or the timer interrupt 4 is found in the step of Sk7, it is further determined by referring to the branch counter value whether it is 3 or not, that is, the timer interrupt 4 (Sk19). If it is not interrupt 4, that is, if it is timer interrupt 3, the passing of the origin of the rotating reels 2L, 2C, 2R (pass of the reel reference position) is checked, and the occurrence of a reel rotation error is detected and stopped. Check if the preparation is complete (whether the stop preparation completion code is set). If the stop preparation is complete and the motor is rotating at a constant speed, operate the stop switch corresponding to the rotating reel. Processing for passing through the origin to be activated (Sk20), determination of whether or not the detection state of the switches has changed, switch input determination processing (Sk21) for performing a transmission request for an operation detection command, etc. are sequentially executed. After, the process proceeds to step of Sk26.

  If the timer interrupt is 4 in the step of Sk19, the stop stored in the work on the stop reel is stored when the stop operation position is stored in the work on the stop reel in accordance with the detection of the stop switches 8L, 8C, 8R. The stop position is determined from the operation position, the stop switch process (Sk23) for calculating the number of steps after which the stop should be performed, and the number of steps until the stop calculated in the stop switch process is counted. A stop process (Sk24) for starting braking by two-phase excitation and a final stop process (Sk25) for three-phase excitation after a certain time from the start of braking in the stop process are sequentially executed, and then the process proceeds to step Sk26.

  In the step of Sk26, the register saved in the stack area in Sk1 is restored, and the processing before the interruption is returned.

  As described above, in this embodiment, the timer interrupt process (main) is executed by interrupting the basic process at regular intervals, and the process counter is updated each time the timer interrupt process (main) is executed. In addition to distributing the load required for one timer interrupt process (main), the power interruption condition based on the voltage drop signal regardless of the process counter value. A power failure determination process is performed to determine whether or not the power failure is satisfied.If the power interruption condition is satisfied, the power interruption processing is performed. Disconnection processing can be performed.

  In the timer interrupt process (main), it is determined whether or not the power interruption condition is satisfied. If the power interruption condition is satisfied, the process proceeds to the power interruption process. Since interruptions due to power interruptions do not occur during execution of interrupt processing (main), interruption processing can be interrupted during execution of timer interruption processing (main), or timer interruption processing (main) Since it is not necessary to wait for the end of the interruption to perform an interruption process associated with power interruption, the process associated with establishment of the power interruption condition is not complicated.

  FIG. 20 is a flowchart showing the control content of the switch input determination process executed by the main control unit 41 in the timer interrupt 3 of the timer interrupt process (main) described above.

  In the switch input determination process, the input data of each switch acquired in the port input process is updated (Sk101), and it is determined whether the detection state indicated by the previous input data is the same as the detection state indicated by the current input data. If the determination is made (Sk102) and the detection state indicated by the previous input data is not the same as the detection state indicated by the current input data, the flow returns to the flowchart of FIG.

  In the step of Sk102, when the detection state indicated by the previous input data is the same as the detection state indicated by the current input data, that is, when the same detection state is indicated for 2.24 ms, the determined data of the corresponding switch. Is updated (Sk103), and the process proceeds to Step S104. In step Sk103, the current confirmed data is moved to the previous confirmed data, and the detection state indicated by the input data determined to be the same as the previous time is set as the current confirmed data.

  In step Sk104, it is determined whether or not the previous confirmed data after the update and the current confirmed data are the same. If the previous confirmed data and the current confirmed data are the same for all the switches, the edge data is determined. Clear (Sk105) and return to the flowchart of FIG.

  In any one of the switches in Sk104, if the previous confirmed data and the current confirmed data are not the same in any one switch, it is determined whether the switch in which the previous confirmed data and the current confirmed data are different from off to on. (Sk106) If there is no switch changed from off to on, the process proceeds to step Sk108. If there is a switch changed from off to on, a rising edge indicating that the corresponding switch has changed from off to on is set. (Sk107), the process proceeds to step Sk108.

  In the step of Sk108, it is determined whether or not the switch in which the final confirmed data and the final confirmed data have changed from on to off, and if there is no switch changed from on to off, the process proceeds to Sk110, and changes from on to off. If there is a switch, a falling edge indicating that the corresponding switch has changed from on to off is set (Sk109), and the process proceeds to Step S110.

  In the step of Sk110, it is determined whether or not there is a switch in which the previous finalized data and the current finalized data are the same. If there is no switch in which the previous finalized data and the current finalized data are the same, the process proceeds to the step of Sk112. If there is a switch in which the previous fixed data and the current fixed data are the same, only the edge data of the corresponding switch is cleared (Sk111), and the process proceeds to Step Sk112.

  In Sk112, an operation detection command transmission request is set, a switch whose detection state has changed (a switch for which edge data is set), whether the switch has changed from off to on, or from on to off (rising edge) Or a falling edge), an operation detection command storage area (operation) assigned to the RAM 507 by generating an operation detection command indicating a detection state (on / off) of another switch (a switch whose detection state has not changed). The operation detection command is temporarily stored until the detection command is transmitted (Sk113), thereby instructing the transmission of the operation detection command, and then the process returns to the flowchart of FIG.

  FIG. 21 is a flowchart showing the control content of the door monitoring process executed by the main control unit 41 in the timer interrupt 2 of the timer interrupt process (main) described above.

  In the door monitoring process, first, a history of the input state of the door opening detection switch 25 (a value obtained by continuing to logically OR the determination state of the positive detection signal of the door opening detection switch 25 acquired in the port input process for about 100 ms). The door sensor history is updated (Sk301). That is, a logical sum of the positive detection signal detection state of the door opening detection switch 25 and the door sensor history is taken as a new door sensor history.

  Next, it is determined whether or not the value of the door monitoring timer is 0, that is, whether or not about 100 ms has elapsed since the previous monitoring (Sk302). If the value of the door monitoring timer is not 0, the value of the door monitoring timer is set. 1 is subtracted (Sk303), the door monitoring process is terminated, and the process returns to the flowchart of FIG.

  If the value of the door monitoring timer is 0 in the step of Sk302, 44 is set as the value of the door monitoring timer (Sk304), and a new time measurement of 100 ms is started. After the door sensor history is acquired in the register and the door sensor history in the RAM 507 is cleared (Sk305), the detection state of the door opening detection switch 25 indicated by the door sensor history acquired in the register and the door command storage area (door) assigned to the RAM 507 are obtained. This is an area where the door command is temporarily stored until the command is transmitted, and is updated to a door command indicating a new detection state when the detection state of the door opening detection switch 25 changes). The detection state of the door opening detection switch 25 indicated by the door command is compared to determine whether or not there is a change in the detection state of the door opening detection switch 25 (Sk306).

  If there is no change in the detection state of the door opening detection switch 25 in the step of Sk306, whether or not the door command transmission request 1 is set, that is, the door command transmission is requested when the main control unit 41 is activated or the game is ended. (Sk307), if the door command transmission request 1 is not set, the door monitoring process is terminated and the process returns to the flowchart of FIG.

  When there is a change in the detection state of the door opening detection switch 25 in the step of Sk306, or when the door command transmission request 1 is set in the step of Sk307, the door command transmission request 1 is cleared and the door command transmission is performed. Request 2 is set (Sk308), and a door command based on the acquired door sensor history (detected state of the door open detection switch 25 after the change) is generated and stored in the door command storage area (Sk309). After instructing the transmission of the door command, the door monitoring process is terminated and the process returns to the flowchart of FIG.

  FIG. 22 is a flowchart showing the control contents of the command transmission process executed by the main control unit 41 in the timer interrupt 2 of the timer interrupt process (main) described above.

  In the command transmission process, first, whether or not the value of the transmission completion flag updated in the step Sk2 of the timer interrupt process (main) in which the command transmission process is performed is 0, that is, the serial number at the start of the timer interrupt process. It is determined whether the communication circuit 511 is transmitting command data or is waiting for command data transmission (Sk401). If the value of the transmission completion flag is 0, that is, the serial communication circuit 511 is transmitting command data, Alternatively, if the command data is waiting to be transmitted, the command transmission process is terminated and the process returns to the flowchart shown in FIG.

  If the value of the transmission completion flag is not 0 in the step of Sk401, it is determined whether the door command transmission request 2 is set, that is, whether the transmission of the door command is instructed (Sk402).

  When the door command transmission request 2 is set in the step of Sk402, the door command transmission request 2 is cleared (Sk403), the door command set in the door command storage area is read and stored in the command buffer ( (Sk404), command storage processing is performed, the door command in the command buffer is transferred to the transmission data register 561 (Sk408), and the process returns to the flowchart shown in FIG.

  If the door command transmission request 2 is not set in the step of Sk402, it is determined whether or not an operation detection command transmission request is set, that is, whether or not an operation detection command transmission is instructed (Sk405). .

  When the operation detection command transmission request is not set in the step of Sk405, the process returns to the flowchart shown in FIG. 18, and when the operation detection command transmission request is set, the operation detection command transmission request is cleared ( (Sk406), the operation detection command set in the operation detection command storage area is read out and stored in the command buffer (Sk407), command storage processing is performed, and the operation detection command in the command buffer is transferred to the transmission data register 561 ( Sk408), the process returns to the flowchart shown in FIG.

  FIG. 23 is a flowchart showing the control contents of the power interruption process (main) executed when the main control unit 41 determines that the power interruption flag is set in the timer interrupt process (main) described above.

  In the power interruption process (main), first, all registers that may be in use are saved in the stack area (Sm1). Note that the values of the I register and IY register described above are used, but are not saved here because the same fixed value is always set with the initialization at the time of startup.

  Next, destruction diagnosis data (5A (H) in this embodiment) is set (Sm2), and all output ports are initialized (Sm3). Next, the RAM parity adjustment data is calculated and set so that the exclusive OR of all the storage areas (including the unused area and the unused stack area) of the RAM 507 becomes 0 (Sm4), and access to the RAM 507 is performed. Prohibited (Sm5).

  Thereafter, the CPU 505 is stopped due to a decrease in voltage, or a user reset signal is input to restart the system.

  When the voltage drops in this standby state, the operation is stopped internally. Therefore, the main control unit 41 reliably stops operation when power is interrupted. Further, in this standby state, when the user reset signal is input without the voltage being lowered, the above-described activation process (main) is executed from the user mode, and if the stored data in the RAM 507 is normal, the process returns to the original process. Will be.

  The main control unit 41 according to the present embodiment has a specific operation state in which a detection signal is output to specify that the setting key switch 37 is ON when the power switch 39 is turned ON from OFF (when the power is turned on). When it is determined that the front door 1b is opened or closed and it is determined that the front door 1b is not in the open state, it is regarded as a fraudulent act and is not controlled to the setting change state. That is, if the front door 1b is not in an open state, the power switch 39 and the setting key switch 37 cannot be operated and cannot enter a specific operation state. When there is a possibility that an illegal act has been performed without being in the open state, the setting change state is not controlled. Thereby, it can control to a setting change state by an unauthorized act, and it can prevent reliably that a setting change is performed.

  Further, as described with reference to FIG. 2, the door opening detection switch 25 and the power box 100 on which the setting key switch 37, the reset / setting switch 38, and the power switch 39 for performing the setting change operation are respectively provided. Since it is provided on different side surfaces in the housing 1a, the difficulty of performing an illegal act on both the door opening detection switch 25 and the power supply box 100 is increased.

  Furthermore, an illegal act may be considered in which the same detection signal as that in the open state is output by the door open detection switch 25 while the front door 1b is closed with respect to the housing 1a. However, as described above, a reflective optical sensor is used as the door opening detection switch 25. For this reason, in order to perform the above fraudulent act, for example, it is difficult to remove the reflecting member. Further, since it can be visually recognized whether or not the reflecting member is removed, it is possible to easily grasp that an illegal act has been performed. Therefore, it is possible to prevent an illegal act such that the door open detection switch 25 outputs the same detection signal as in the open state while the front door 1b is closed with respect to the housing 1a.

  On the other hand, when the power switch 39 is turned from OFF to ON (when the power is turned on), the front door 1b when the setting key switch 37 enters a specific operation state in which a detection signal for specifying ON is output. When it is in the open state, the state shifts to the setting change state, and during this time, the open / close state of the front door 1b is not determined. For this reason, after shifting to the setting change state, this setting change state is continued until the setting key switch 37 is turned off regardless of the open / closed state of the front door 1b. That is, after the transition to the setting change state, the setting change state is maintained regardless of the open / closed state of the front door 1b until the setting key switch 37 is turned OFF and the setting end condition is satisfied. For this reason, after the operation of the power switch 39 and the setting key switch 37 is properly performed, not an unauthorized act, and the setting change state is controlled, for example, the door open detection switch is touched by mistake during the setting change. Even if it is erroneously detected that the front door 1b is closed, the setting change state can be maintained and the setting change can be performed reliably. For this reason, there is no need for the game hall manager to be bothered by having to turn off the power again to change the setting from the beginning due to an erroneous operation.

  Further, when the power switch 39 is switched from OFF to ON (when the power is turned on), the main control unit 41 enters a specific operation state in which a detection signal for specifying the setting key switch 37 to be ON is output. When the open / close state of the front door 1b is determined and it is determined that the front door 1b is not in the open state, it is regarded as a fraudulent act and not only the setting change state is not controlled, but also the progress of the game is disabled. ing. This disabling is not canceled even if the reset switch 23 or the reset / setting switch 38 is operated as in the case of the RAM abnormality error, and is canceled until a new setting value is set in the setting change state described above. It will not be done. For this reason, it is easily specified by the game hall manager or other players that the illegal act has been performed. As a result, fraud can be suppressed by increasing the risk of fraud.

  In addition, as described above, when a new setting value is set in the setting change state, the disabling of the game is canceled, so that the game is easily disabled for the person who has performed the illegal act. If it is a person who can operate the setting key switch with the front door 1b opened (for example, a game hall manager), the immobilization can be canceled easily and quickly. Can do.

  In this embodiment, the open / closed state of the front door 1b when the specific operation state is reached is determined. When it is determined that the front door 1b is not open and the progress of the game is disabled, the setting change state In this configuration, the disabling is canceled on the condition that a new set value is set, but the present invention is not limited to this, as long as the disabling is canceled by performing a predetermined canceling operation. For example, when the front door 1b is opened or closed when it is in a specific operation state, and it is determined that the front door 1b is not open and the progress of the game is disabled, the setting key switch 37 is turned on. As long as it is in a state, the game may be disabled and the setting key switch 37 may be turned off to release the disabled state. Even in this case, it is easy for a person who has performed an illegal act. Impossibility of play If it is a person who can operate the setting key switch with the front door 1b opened (for example, a game hall manager), the immobilization can be canceled easily and quickly. Can do.

  Also, in this embodiment, the open / close state of the front door 1b when the specific operation state is reached is determined, and when it is determined that the front door 1b is not in the open state, the game is disabled by controlling to an error state. However, at least the configuration in which the progress of the game is disabled is sufficient, and for example, a configuration in which the operation for progressing the game is invalidated may be used.

  Further, in the present embodiment, the example in which the setting value for setting the degree of advantage is a value for specifying the probability (winning rate) that it is determined that the occurrence of winning is permitted is described. For example, in a slot machine that executes a navigation effect in which information corresponding to a winning situation is notified or is controlled at an assist time (AT) for executing the navigation effect. May be a value that specifies the probability of executing the navigation effect or the probability of controlling to AT. Further, in a slot machine that is controlled to a replay time (RT) in which the winning probability of a re-gamer is improved by a specific symbol combination, a value that specifies the probability of controlling to the RT may be used. In this way, the winning rates may be the same as long as the player's advantage differs according to the set value.

  In this embodiment, the example in which the setting confirmation process is performed in the BET process on the condition that the setting key switch 37 is in the ON state has been described. When the switch 37 is in an ON state, it is determined whether or not the front door 1b is in an open state. When the front door 1b is in an open state, the setting confirmation processing can be performed, and the front door 1b is in a closed state. In some cases, the setting confirmation process may not be performed. Furthermore, when the front door 1b is in a closed state, in addition to not shifting to the setting confirmation process, the game may be disabled. Accordingly, when there is a possibility that the setting key switch 37 is turned on due to an illegal action and a setting confirmation operation is performed, it is possible to reliably prevent the setting value from being checked by the setting confirmation processing. .

  In the present embodiment, the main control unit 41 outputs a detection signal for specifying that the setting key switch 37 is ON when the power switch 39 is switched from OFF to ON (when the power is turned on). Initialization 1 in which all areas (including the unused area and the unused stack area) other than the used stack area and the non-initialized area are initialized in the storage area of the RAM 507 when the specific operation state is entered. After that, when the front door 1b is opened and closed, and it is determined that the front door 1b is not in the open state, it is regarded as fraudulent behavior and the setting change state is not controlled. When 39 is changed from OFF to ON (when the power is turned on), when the setting key switch 37 enters a specific operation state in which a detection signal for specifying ON is output, When the open / close state of 1b is determined and it is determined that the front door 1b is in the open state, initialization 1 is performed at least at any timing before the transition to the setting change state or after the transition to the setting change state. On the other hand, when it is determined that the front door 1b is not in the open state, it is regarded as a fraudulent act and may not be controlled to the setting change state, and may not be initialized 1. Originally, if the front door 1b is not in the open state, the power switch 39 and the setting key switch 37 cannot be operated, and the setting cannot be changed. However, the front door 1b is opened in the specific operation state. When there is a possibility that an illegal act has been performed without being in the state, the setting is not controlled and the data in the RAM 41c is not initialized. Therefore, it is possible to prevent the settings from being changed due to a fraudulent act, and to prevent the data from being initialized at that time. It can be held without becoming.

  Next, commands that the main control unit 41 transmits to the sub control unit 91 will be described.

  In this embodiment, the main control unit 41 sends a BET command, a credit command, an internal winning command, a freeze command, a reel rotation start command, a reel stop command, a winning determination command, a payout start command, a payout end to the sub control unit 91. A plurality of types of commands including commands, gaming state commands, standby commands, stop commands, error commands, return commands, setting commands, setting confirmation commands, door commands, and operation detection commands are transmitted.

  These commands consist of 1-byte type data indicating the command type and 1-byte extension data indicating the command content, and the sub-control unit 91 can determine the command type 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 bet number is set by operating the single BET switch 5 or the MAXBET switch 6 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 that has been 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 freeze command is a command indicating whether or not to control the freeze state when it is determined to control to the freeze state described later, and the timing when controlling to the freeze state. Sometimes sent.

  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 is a command that can specify whether the reel to be stopped is the left reel, the middle reel, or the right reel, the area number of the corresponding reel stop operation position, and the area number of the corresponding reel stop position. And is transmitted each time stop control is performed in accordance with the stop operation of each reel. 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 at the end of the game.

  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.

  The return command is a command indicating that the main control unit 41 has returned to the control state before the power interruption, and is transmitted when the main control unit 41 returns to the control state before the power interruption.

  The setting command is a command indicating the start or end of the setting change state and the setting value after the setting change. At the time of transition to the setting change state, a setting command indicating the start of the setting change state is transmitted, and when the setting change state ends. A setting command indicating the end of the setting change state and the setting value after the setting change is transmitted. Further, since the control state of the main control unit 41 is initialized with the transition to the setting change state, it can be specified that the control state of the main control unit 41 has been initialized by the setting command indicating the start of setting. .

  The setting confirmation command is a command that indicates the start or end of the setting confirmation state. A setting confirmation command that indicates the start of setting confirmation is transmitted when entering the setting confirmation state, and the setting confirmation end is indicated when the setting confirmation state ends. A confirmation command is sent.

  The door command is a command indicating the detection state of the door opening detection switch 25, that is, on (open state) / off (closed state), when the power is turned on, at the end of one game (after the game is over, the bet number of the next game) Sent before the setting of ”can be started), and when the detection state of the door opening detection switch 25 changes (from on to off, from off to on).

  The operation detection command is an operation switch (one BET switch 5, MAXBET switch 6, start switch 7, stop switch 8L, 8C, 8R) of which the detection state (on / off) has changed, from the detection state off. This command indicates whether it has changed to on or from on to off, and the detection state (on / off) of another switch, and is transmitted when the detection state of any of these operation switches has changed.

  Of these commands, commands other than the door command and the operation detection command are generated in the basic process, and the command data in the command buffer assigned to the non-initialized area is updated to the newly generated command data, and the serial communication circuit The data is transmitted to the sub-control unit 91 by being transferred to the transmission data register 561 of 511.

  On the other hand, the door command is generated in the door monitoring process of the timer interrupt process (main) and stored in the door command storage area. The door command storage area stores a door command indicating the detection state of the door opening detection switch 25 at the time of power-on or at the end of one game, and when the detection state of the door opening detection switch 25 changes, A door command indicating the detection state is stored. Further, the door command stored in the door command storage area is not cleared even after the door command is transmitted, and is then overwritten by a newly stored door command. When the power is turned on or one game is finished, a door command transmission request 1 for requesting transmission of a door command stored in the door command storage area is set, and whether the door command transmission request 1 is set or whether the door is open is detected. When the detection state of the switch 25 changes, the door command transmission request 2 is set. When the door command transmission request 2 is set, the door command stored in the door command storage area is set. In the command transmission process of the timer interrupt process (main) executed after transmission is instructed, it is stored in the command buffer and transferred to the transmission data register 561 of the serial communication circuit 511 to be transmitted to the sub-control unit 91. The

The operation detection command is used when a change in the detection state of any switch is detected in the switch input determination process of the timer interrupt process (main) (when edge data of any switch is set). is generated, together with Ru stored in the operation detection command storage area, the transmission of the operation detection command operation detection command transmission request is stored in the operation detection command storage area by being set is an instruction, the timer split to be subsequently executed In the command transmission processing of the main processing (main), the data is stored in the command buffer and transferred to the transmission data register 561 of the serial communication circuit 511 to be transmitted to the sub-control unit 91.

  As described above, both the door command and the operation detection command are stored in the command buffer in the command setting process of the timer interrupt process (main), and transferred to the transmission data register 561 of the serial communication circuit 511 so that the sub-control unit 91 If the door command transmission request 2 is set, that is, if the door command transmission is requested, even if the operation detection command is requested to be transmitted, the door command is transmitted. Since the operation detection command is transmitted only when the door command transmission request 2 is not set, both the door command transmission request 2 and the operation detection command transmission request are set. If the command is sent, the command transmission process sends a door command and sends the next command. Operation detection command in the processing is to be transmitted.

  Also, as shown in FIG. 24A, the serial communication circuit 511 completes transmission of the status register 563 when untransmitted command data remains in the transmission data register 561 or command data is being transmitted. When the transmission of the command data stored in the transmission data register 561 is completed, the transmission completion value of the status register 563 is set to 1. The value of the status register 563 can be referred to by the CPU 505. The CPU 505 first acquires the transmission completion value from the status register 563 after saving the register in the timer interrupt process (main). Based on the value, the value of the transmission completion flag in the RAM 507 is updated.

  In the command transmission process, first, the value of the transmission completion flag stored in the RAM 507 is confirmed. As shown in FIG. 24B, when the value of the transmission completion flag is 1, that is, command data is not transmitted. Or only when it indicates that the transmission of the command data is completed, the transfer of the door command or the operation detection command to the transmission data register 561 is permitted, and when the value of the transmission completion flag is 0, That is, when there is untransmitted command data remaining in the transmission data register 561 or when command data is being transmitted, even if the door command transmission request 2 is set, the transmission to the door command transmission data register 561 is performed. Transfer is prohibited, and even if an operation detection command transmission request is set, the operation detection command transmission data register Transfer to 561 is adapted to be inhibited.

  In particular, the operation detection command is requested to be transmitted when the switch detection state changes regardless of whether it is invalid or valid. Although the transmission of the command accompanying the game progress control will be delayed, the operation detection command is transmitted only when the command data has not been transmitted or the command data has been transmitted as described above. Since transfer to 561 is permitted, it is possible to prevent the effects related to the progress control of the game from being delayed with the transmission of the operation detection command.

  In this embodiment, a command (hereinafter referred to as a first command) triggered by an event associated with the progress control of the game is generated in the basic process and transferred to the transmission data register 561 to transfer the serial communication circuit 511. Is transmitted to the sub-control unit 91, but a command (hereinafter referred to as a second command) triggered by an event that may occur regardless of the progress of the game, such as a door command or an operation detection command, is basically It is generated by a timer interrupt process (main) executed by interrupting the process periodically. In addition, since the command is composed of 2-byte data, if the configuration is such that the second command is immediately transferred to the transmission data register 561 when the second command is generated, it may be accompanied by game progress control in the basic process. After transferring the first byte of command data, the timer interrupt process is interrupted and executed before transferring the second byte, and the second command is inserted between the first byte and the second byte of the first command data. May be received and cannot be received as a regular command on the sub-control unit 91 side.

  On the other hand, in the present embodiment, as described above, the transmission completion value in the status register 563 of the serial communication circuit 511 is acquired at the beginning of the timer interrupt process (main), the transmission completion flag in the RAM 507 is updated, and transmission is performed. When 0 is set as the completion flag, that is, when any command remains in the transmission data register 561 or a command is being transmitted, the transfer of the second command to the transmission data register 561 is prohibited. Thus, the second command does not enter between the command data of a plurality of bytes constituting the first command.

  In the present embodiment, in the timer interrupt process (main), the value of the completion of transmission in the status register 563 is not checked immediately before the second command is transferred to the transmission data register 561, but the timer interrupt process ( The transmission completion flag of the status register 563 acquired at the beginning of the main) is acquired to update the transmission completion flag, and the value of the transmission completion flag is referenced immediately before the transfer of the second command to the transmission data register 561. It is determined whether the transfer of the second command to the transmission data register 561 is prohibited or permitted.

  As shown in FIG. 24B, after the command data of the first byte constituting the first command is transferred to the transmission data register 561, the command data of the second byte constituting the first command is transferred. When the timer interrupt process (main) is executed at the stage before transfer, before determining whether to prohibit or permit the transfer of the second command to the transmission data register in this timer interrupt process (main), Transmission of the command data of the first byte constituting the first command is completed, the value of transmission completion of the status register 563 becomes 1, and the command data of the second byte constituting the first command is transmitted. 1st byte command data and 2nd byte command data constituting the first command on the assumption that there is no untransmitted first command data. This is because the second command data may be transmitted in the meantime, and the transmission completion value of the status register 563 acquired at the beginning of the timer interrupt processing (main) is acquired as in this embodiment. Then, the transmission completion flag is updated, and the transfer of the second command to the transmission data register 561 is prohibited by referring to the value of the transmission completion flag immediately before the transfer of the second command to the transmission data register 561. Before determining whether to prohibit or permit the transfer of the second command to the transmission data register in the timer interrupt process (main). Even if the transmission of the command is completed and the transmission completion value of the status register 563 becomes 1, the transfer of the second command to the transmission data register is surely prohibited. It becomes possible, during the first byte of command data and 2 bytes of the command data constituting the first command, it is possible to the second command data reliably prevented from being transmitted.

  In this embodiment, the timer interrupt process (main) starts, and after saving the register, the transmission completion value of the status register 563 is acquired immediately. At least the timer interrupt process (main) Is the stage before the transfer of the second command to the transmission data register, and after the timer interrupt processing (main) starts, the serial communication circuit 511 completes the transmission of the command data of the first byte. The transmission completion value of the status register 563 may be acquired before the time required for updating the transmission completion value elapses.

  In the present embodiment, the drive control of the reel motors 32L, 32C, and 32R configured by the stepping motor is performed in the timer interrupt process (main), and the first command is transferred to the transmission data register 561. In the timer interrupt process (main), the transfer of the second command is prohibited in the timer interrupt process (main). Since the second command is prevented from entering, the excitation time of the phases of the reel motors 32L, 32C, 32R is constant, and the reel motors 32L, 32C, 32R can be driven stably.

  In this embodiment, the door command and the operation detection command are applied as commands triggered by an event that can occur regardless of the progress of the game. Any command that is required to be transmitted in the interrupt process (main) may be used, and a command indicating that an error that may occur unexpectedly, such as vibration of a gaming machine, may be applied as the second command.

  In this embodiment, when any command remains in the transmission data register 561 or when a command is being transmitted, the transfer of the second command to the transmission data register 561 is uniformly prohibited. As shown in FIG. 19B, the command transfer assigned to the RAM 507 before transferring the command data of the first byte (Sx1) in the command storing process for transferring the command data to the transmission data register 561 in the basic process. Set the value of the completion flag area to 0 (Sx0), set the value of the command transfer completion flag area to 1 after completing the transfer of the second byte of command data (Sx2) (Sx3), and timer interrupt processing Only when the command transfer completion flag value is set to 1 in the (main) command setting process Transfer of the second command to the transmission data register 561 is permitted, and when the command transfer completion flag value is set to 0, transfer of the second command to the transmission data register 561 is prohibited. With this configuration, as shown in FIG. 24C, after all the command data constituting the first command is transferred to the transmission data register 561, the last command data ( Even if the second byte) still remains in the transmission data register or transmission shift register 562 and transmission is not completed (the transmission completion value in the status register 563 is 0), the second command Transfer to the transmission data register 561 is permitted, the second data is transmitted between the command data of a plurality of bytes constituting the first command. On top never intrudes command data constituting a command, a period during which transmission of the second command is prohibited can be minimized.

  The main control unit 41 monitors the detection state of the door opening detection switch 25 about every 100 ms. Specifically, in any of the timer interrupts 1 to 4 of the timer interrupt process (main), that is, in the port input process performed every 0.56 ms, an input state (door) in which the detection signal from the door open detection switch 25 is converted to a positive logic Open detection switch 25on = 1, 0 is acquired when the door is closed, and is performed by timer interrupt 2 of the timer interrupt process (main), that is, in the door monitoring process performed every 2.24 ms, in the port input process described above The acquired state of the detection signal of the door opening detection switch 25 (the input state that has been the same for two consecutive times) continues to be logically ORed for about 100 ms (45 times of door monitoring processing), and the door opening detection switch is used using the result. 25 detection states are determined. When the calculation result is 1 when about 100 ms elapses, that is, when the door opening detection switch 25 is turned on (opened) even once during that time, it is determined that the door opening detection switch 25 is on. If the calculation result is 0, that is, if the door opening detection switch 25 is not turned on (opened) during that time, it is determined that the door opening detection switch 25 is off. If the result of this determination and the detection state of the door opening detection switch 25 indicated by the door command stored in the door command storage area match, it is determined that the detection state of the door opening detection switch 25 has not changed. Otherwise, it is determined that the detection state of the door opening detection switch 25 has changed, the door command stored in the door command storage area is updated to a door command indicating the detection state after the change, and the door command transmission request 2 is set. Then, the transmission of the door command is instructed. Further, when the main control unit 41 determines that the detection state of the door opening detection switch 25 has changed, the main control unit 41 updates the output state of the door opening signal to the external output board 1000 in addition to the door command transmission command.

  The main control unit 41 sets the door command transmission request 1 in the activation process or the game process when the power is turned on or at the end of one game, and requests transmission of the door command stored in the door command transmission buffer. On the other hand, in the door monitoring process, it is determined whether or not the door command transmission request 1 is set. If the door command transmission request 1 is set, it is determined that there is a door command transmission request and the door command transmission is performed. Request 2 is set to command transmission of the door command stored in the door command storage area. Further, when the door command transmission request 1 is set, the main control unit 41 updates the output state of the door opening signal to the external output board 1000 in addition to the door command transmission command.

  As described above, the output state of the door opening signal to the external output board 1000 is updated by linking to the door command transmission command.

  The slot machine 1 of the present embodiment includes a single BET switch 5, a MAXBET switch 6, a start switch 7, and stop switches 8L, 8C, and 8R as operation switches for the main control unit 41 to control the progress of the game.

  The operation of these switches is not always related to the progress control of the game in all control states constituting from the end of the game to the end of the next game, but is related to the progress control of the game according to the control state. Sometimes it may not be involved.

  The main control unit 41 detects these operation switches in a switch input determination process executed during a timer interrupt process (main) executed by interrupting at regular time intervals. In the switch input determination process, the detection state of the operation switch is monitored, and when any operation switch changes from off to on, edge data (rising edge) indicating that the corresponding operation switch changes from off to on Is set, edge data (falling edge) indicating that the corresponding operation switch has changed from on to off is set.

  Then, the main control unit 41 determines whether or not the operation switch has been operated based on whether or not the rising edge of the operation switch related to the progress control of the game is set according to the control state at the current stage in the game process. If it is determined that the operation switch is operated, all the edge data is cleared, and the game progress control is executed according to the operation switch operation, and the game progress control is performed. The accompanying commands (BET command, internal winning command, reel stop command, etc.) are transferred to the transmission data register 561 of the serial communication circuit 511 and transmitted to the sub-control unit 91. Even if the operation of any one of the operation switches is detected and the edge data is set, if it is not cleared by the next switch input determination process, it is cleared by the next switch input determination process.

  When determining that the rising edge of the stop switch corresponding to the rotating reel is set in the reel rotation processing, the main control unit 41 determines whether the detection state of the other operation switches is on. When it is determined that the detection state of the other operation switch is on, that is, when the operation of the stop switch corresponding to the rotating reel is detected while the other operation switch is being operated, this is effective. The stop operation of the corresponding reel is not performed without the stop operation.

  This is because, when two or more operations are detected among the stop switches 8L, 8C, and 8R, if priority is given to the stop control based on one of the operations, the other stop control is delayed, and the stop mode of the reel This is because there is a possibility that a problem such as unnaturalness may occur, and even if the operation of the stop switch corresponding to the rotating reel is detected while the other operation switches are operated as described above, By not performing the stop control of the reel to be performed, the stop control of the other reel is not delayed by the stop control of the one reel.

  Further, when the main control unit 41 determines that the rising edge of the stop switch corresponding to the rotating reel is set in the reel rotation processing, the detection state of the other operation switch is not limited to the other stop switch. If the detection state of any of the other operation switches is determined to be on, the effective stop operation is not performed and the corresponding reel stop control is not performed. Without extracting only the detection state of the stop switch from the detection state of the operation switch, for example, when on is set to 1 and off is set to 0, the sum of the detection states of all the operation switches is calculated. If the number is two or more, the detection states of all the operation switches can be collectively determined, for example, the other operation switches are determined to be in the detection state.

  When the main control unit 41 determines a change in the detection state of any of the operation switches in the above-described switch input determination process, the main control unit 41 sets the edge data, and is a switch in which the edge data is set, a rising edge, An operation detection command indicating whether it is a falling edge or a detection state of another switch is generated, stored in the operation detection command storage area, and an operation detection command transmission request is set.

  When the operation detection command transmission request is set, the operation detection command stored in the operation detection command storage area is read out in the command transmission process in the timer interrupt process (main), and the serial communication circuit 511 The data is transferred to the transmission data register 561 and transmitted to the sub-control unit 91.

  As described above, in this embodiment, the main control unit 41 sub-controls an operation detection command that can specify that the single BET switch 5, the MAXBET switch 6, the start switch 7, and the stop switches 8L, 8C, and 8R are operated. The operation switch detected by the main control unit 41 is transmitted to the unit 91 regardless of whether or not the sub control unit 91 is an operation switch related to the game progress control in each control state. It is possible to specify that an operation has been performed, and an effect can be executed in accordance with the operation of an operation switch that is not involved in the progress control of the game.

  In this embodiment, only when the detection state (on / off) of one of the operation switches is changed, an operation detection command indicating that is transmitted. Regardless of whether the switch 5, the MAXBET switch 6, the start switch 7, or the stop switches 8L, 8C, 8R is operated, the one-sheet BET switch 5, the MAXBET switch 6, the start switch 7, the stop switches 8L, 8C , 8R may be configured to transmit an operation detection command that can specify the on / off state at regular intervals. Even in such a configuration, the sub-control unit 91 side detects the operation detection command. It is possible to identify the operation switch that has been operated, and the operation switch that does not participate in the game progress control. It is possible to perform the production in accordance with the work.

In this embodiment, a command associated with the progress control of the game is generated in the basic process, transferred to the transmission data register 561, and transmitted to the sub-control unit 91, but is not involved in the progress control of the game. The operation detection command accompanying the operation of the operation switch is generated in the switch input determination process of the timer interrupt process (main), transferred to the transmission data register 561 in the subsequent command transmission process of the timer interrupt process (main), Although it is a structure transmitted to the control part 91, it is determined whether operation of the operation switch in connection with game progress control was detected in the basic process, and operation of the operation switch in connection with game progress control was detected. Control the game in the event that the It is temporarily stored in the buffer, and it is also determined whether or not an operation not involved in the game progress control is detected in the basic process, and the operation of the operation switch is detected when the operation switch operation not involved in the game progress control is detected. An operation detection command indicating that an operation not involved in the control has been detected is generated, temporarily stored in the command buffer in the same manner as the command accompanying the game progress control , and then waiting for transmission in the timer interrupt process (main) When the command is stored in the command buffer, the command may be transferred to the transmission data register 561 and transmitted to the sub-control unit 91. With such a configuration, the control state of the basic process is related. Therefore, it is possible to share command transmission control.

  In addition, when such a configuration is adopted, there is a possibility that a plurality of transmission waiting commands may be stored before the command stored in the command buffer is transmitted in the next timer interrupt process (main). If a plurality of commands are transmitted continuously, the sub-control unit 91 may be missed, and the processing time of the timer interrupt process (main) becomes long, and the basic process is stagnant. Therefore, when there are a plurality of commands stored in the command buffer, it is preferable to transmit only one command per timer interrupt process (main). However, if only one command is transmitted per timer interrupt process (main), the command transmission timing will be delayed.

  On the other hand, in the case of adopting the above configuration, when the operation switch operation involved in the game progress control and the operation switch operation not involved in the game progress control are detected at the same time, There is a possibility that an operation detection command accompanying the operation of the operation switch not involved in the game progress control is generated at the same time and stored in the command buffer. In this case, in the subsequent timer interrupt process (main), it is preferable to prioritize the transmission of the command associated with the game progress control over the operation detection command. The transmission is not delayed, and it is possible to prevent the presentation according to the operation related to the game progress control from being delayed due to the influence of the operation not related to the game progress control.

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

  When the sub control unit 91 receives a command from the main control unit 41, the sub control unit 91 executes a command reception interrupt process. 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.

  The reception buffer is provided with an area capable of storing a maximum of 16 commands so that a plurality of commands can be accumulated.

  In the timer interrupt process (sub), the sub-control unit 91 determines whether or not an unprocessed command is stored in the reception buffer. If an unprocessed command is stored, the sub-control unit 91 is the earliest. The control pattern table stored in the ROM 91b is referred to based on the command received in the stage, and the liquid crystal display 51, effect effect LED 52, speakers 53, 54, reel LED 55, etc. are controlled based on the control contents registered in the control pattern table. Performs output control of various rendering devices.

  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. Control patterns of these effect devices are registered, and when the sub-control unit 91 receives a command, the sub-control unit 91 stores the control patterns registered corresponding to the effect patterns set in the RAM 91c in the game of the control pattern table. Among these, the control pattern corresponding to the type of the received command is referred to, and the 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-control unit 91 receives a new command during execution of an effect triggered by the reception of a certain command, the sub-control unit 91 stops the effect based on the control pattern being executed, and changes to the newly received command. An effect based on the corresponding 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 received 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 the betting number setting operation is performed during the execution of the effect, that is, when the sub-control unit 91 receives a BET command indicating that the bet number has been set, Is to be canceled. 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 betting amount adjustment operation is performed during the performance, that is, after the sub-control unit 91 receives a game state command indicating the end of the game, it receives an internal winning command indicating the start of the game. When the payout start command is received before, the effect 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 control unit 91 receives the internal winning command, the sub control unit 91 stores the effect pattern in the effect table according to the result of the internal lottery indicated by the internal winning command. With reference to the registered selection rate, one of the effect patterns is selected from a 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.

  As described above, the first embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the first embodiment, and the present invention can be modified or added without departing from the gist of the present invention. Needless to say, it is included.

  In the first embodiment, a slot machine to which medals are applied as a game medium used for setting a bet number and giving a 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 game balls as game media, 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 first 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.

  In the first embodiment, an example in which the slot machine is applied as an example of the gaming machine has been described. However, the gaming machine is capable of performing a predetermined game, and the opening / closing body provided to be opened and closed and the opening / closing body are opened. Production based on the control information received from the operation means that can be operated in the state, the open / close state detection means for detecting the open / close state of the open / close body, the game control means for controlling the progress of the game, and the game control means The present invention can be applied to any game machine provided with an effect control means for performing the above control, and the present invention may be applied to a pachinko game machine in which a game ball is ejected to play a game.

  Next, a slot machine according to a second embodiment to which the present invention is applied will be described. Since the slot machine of the present embodiment has a configuration similar to that of the first embodiment, detailed description of the same configuration is omitted, and different points are mainly described here.

  In the first embodiment, when determining that the front door 1b is not in the open state in the step Sa32 of the start-up process (main), the main control unit 41 sets an error code indicating an abnormality setting operation in the register (Sa33). Then, an error command indicating an abnormal setting operation is generated and stored in the command buffer (Sa34), command storage processing is performed, the error command in the command buffer is transferred to the transmission data register 561 (Sa30), and interrupts are permitted. (Sa31), the error processing, that is, the configuration for shifting to the error setting operation error state, but in this embodiment, as shown in FIG. 25, it is determined that the front door 1b is not in the open state in step Sa32. The setting key switch 37 is in the ON state but the front door 1b is not in the open state. Sets a flag (SA35), the process proceeds to Sa18. When the door closing state flag at the time of setting is set, as will be described later, the progress of the game control is stopped and disabled at a predetermined timing.

  In the first embodiment, the main control unit 41 shifts to the game process after performing the command storage process in the Sc15 step of the setting change process, whereas in the present embodiment, as shown in FIG. After this step, it is determined whether or not a setting door closed state flag or a disabling flag for disabling the game is set (Sc16). When it is determined that the flag is not set in the step of Sc16, the process proceeds to the game process as it is, whereas when it is determined that the flag is set in the step of Sc16, the flag that is set is set. Is cleared (Sc17), and the process proceeds to a game process. As a result, once the set-time door closing state flag or the disabling flag is set, the flag is not cleared until the state is changed to the setting change state, so that the game can be disabled.

  In the first embodiment, when the setting key switch 37 is not on in the Se14 step of the BET process or when the value of the BET counter is not 0 in the Se15 step, the main control unit 41 proceeds to the Se19 step. In this embodiment, the inserted medal sensor 31 determines whether or not the passage of the inserted medal is detected, that is, the presence or absence of the inserted medal flag indicating that the passage of the inserted medal is detected. As shown in FIG. 27, when the setting key switch 37 is not on in the Se14 step of the BET process or when the value of the BET counter is not 0 in the Se15 step, the process proceeds to the Se65 step and the door is closed at the time of setting. It is determined whether the status flag is set. When it is determined that the door closing state flag at the time of setting is set, the process proceeds to step Se66, and it is determined whether or not a currently valid specific operation has been detected. The detection of the specific operation currently effective means detection of the inserted medal sensor 31, detection of the single BET switch 5, detection of the MAXBET switch 6, detection of the settlement switch 10, and the like.

  Note that the specific operation is effectively detected until the operation to the start switch 7 to be described later is detected even when the set door closing state flag is set, and the corresponding processing is performed. (For example, processing when it is determined YES in each of Se19, Se41, Se49, and Se58).

  When it is determined in Se66 that a currently valid specific operation has been detected, the process proceeds to step Se67, and the disabling flag for disabling the operation of the game by disabling the operation of the start switch 7 and disabling the game. Set. On the other hand, when it is determined at Se65 that the set-time door closed state flag is not set, when it is determined at Se66 that a currently valid specific operation is not detected, and when the disabling flag is set at Se67. The process proceeds to Se19.

  Also, in the first embodiment, if the value of the BET counter is a specified number in the step of Se36, the value of the random number storage work is set in the lottery work as a random value for internal lottery (Se37), and interruption is permitted. (Se38), the insertion impossible flag is set in the RAM 507, the flow path switching solenoid 30 is turned off, and the insertion of a new medal is prohibited with the medal flow path as the path on the medal payout exit 9 side (Se39). In this embodiment, as shown in FIG. 27, if the value of the BET counter is a prescribed number in the step of Se36, the setting at the start of the game is performed (Se40). move on. In Se68, it is determined whether or not the disabling flag is set. Normally, the setting change operation cannot be performed unless the front door 1b is opened. When it is determined in Se68 that the disabling flag is set, the front door 1b is displayed when the setting change operation is performed. Since it is at the time of an abnormality such as being in a closed state, the process proceeds to a loop process that does not perform any process. Thereby, the game is disabled until the setting change state is entered. For this reason, it is easily specified by the game hall manager or other players that the illegal act has been performed. As a result, fraud can be suppressed by increasing the risk of fraud.

  Further, regardless of the progress status of the game immediately before being disabled, the operation of the start switch 7 when the disable flag is set is invalidated, and therefore disabled when the start switch 7 is operated. The process of determining whether or not the flag is set is performed, and when the disablement flag is set, the process proceeds to the loop process so that the progress of the game thereafter can be disabled. For this reason, the process for disabling can be facilitated, and it is not necessary to perform special control for disabling, and an increase in processing load can be prevented.

  When the game is disabled, for example, when the power is turned on again without turning the setting key switch ON, the process proceeds to the loop process. For this reason, the immobilization cannot be canceled. On the other hand, when the game is disabled, for example, when the front door 1b is opened and the setting key switch is turned on and the power is turned on again, the process shifts to the setting change process of FIG. By disabling the immobilization flag in Sc17, the immobilization can be canceled. As described above, the immobilization of the game is canceled by properly shifting to the setting change state. Therefore, a person who has performed a fraudulent act cannot easily release the disabled game, but a person who can operate the setting key switch 37 with the front door 1b opened (for example, a game hall) If it is an administrator), the immobilization can be canceled easily and quickly.

  As described above, the second embodiment of the present invention has been described with reference to the drawings. However, the present invention is not limited to the second embodiment, and the present invention can be modified or added without departing from the gist of the present invention. Needless to say, it is included. Further, the same or similar configuration as the first embodiment has the same effect as that described in the first embodiment. Further, the modified example illustrated for the first embodiment is also applicable to the second embodiment.
