The main control CPU 100a is configured to be able to input various operation signals that are output when the bet button 18, the settlement button 19, the start lever 20, and the stop buttons 21a to 21c are operated.

  The main board 100 is connected to the actuators A1 to A3. The main control CPU 100a controls the operation of the actuators A1 to A3 of the reels 16a to 16c by controlling the output mode of control signals (pulse signals) to the actuators A1 to A3 of the reels 16a to 16c. It is configured to be possible.

  In the main board 100, random numbers used for various lottery processes are generated. For example, the random number is generated as a hardware random number by providing a random number generation circuit that updates a value every time a clock signal is input, or a random number update in which the main control CPU 100a updates a value every predetermined control cycle. By executing the processing, it can be generated as a software random number. For the random numbers generated in the main board 100, for winning information determination used to determine winning information (for example, winning numbers) that can identify symbol combinations (combinations) that can be derived and displayed (winning) in the variable game. There are random numbers. In the slot machine 10 of the present embodiment, each winning information is associated with one or a plurality of symbol combinations that can be derived and displayed in the variable game.

  The main control ROM 100b stores a main control program. In addition, the main control ROM 100b stores various tables used for execution of processing relating to the variable game. Examples of such a table include a winning information determination table for determining winning information from a plurality of winning information. The main control RAM 100c stores various information such as the above-described winning information. Information stored in the main control RAM 100c is updated as needed during the operation of the slot machine 10. In the following description, storing and updating information may be collectively referred to as “rewrite”.

Here, the storage area of the main control RAM 100c will be described in detail.
As shown in FIG. 3, addresses from “F000H” to “F3FFH” are assigned to the storage area of the main control RAM 100c in the present embodiment. Hereinafter, for convenience of explanation, a storage area to which addresses in the first range from “F000H” to “F1FFH” are assigned is referred to as “first storage area”, while a storage area in the second range from “F200H” to “F3FFH” is indicated. A storage area to which an address is assigned is referred to as a “second storage area”. In the present embodiment, the first storage area corresponds to the first area, while the second storage area corresponds to the second area. In the following description, “rewriting the storage contents of the storage area” includes both rewriting part of the storage contents of the storage area and rewriting all of the storage contents of the storage area.

  The first storage area and the second storage area in the present embodiment are storage areas obtained by dividing the address range in which rewriting of information is allowed in the slot machine 10 into a plurality (two in this embodiment). In the present embodiment, the first storage area is a storage area assigned to an address before the address assigned to the second storage area in the storage area of the main control RAM 100c. In the present embodiment, a work area, a stack area, and an unused area are set in the first storage area and the second storage area, respectively.

  In the present embodiment, the first storage area and the second storage area are configured to be initialized independently. For example, the main control CPU 100a initializes the second storage area while the second storage area is initialized. Processing that does not initialize one storage area is possible. In the present embodiment, the first storage area and the second storage area have different processes for rewriting the storage contents of each storage area. Specifically, the first storage area is configured not to be rewritten in the process of rewriting the second storage area among the processes performed by the main control CPU 100a. The second storage area is configured not to be rewritten in the process of rewriting the first storage area among the processes performed by the main control CPU 100a. The relationship between the processing performed by the main control CPU 100a and the rewritten storage area will be described in detail later.

  In addition, the storage contents stored in the first storage area and the second storage area in the present embodiment are different. In the present embodiment, information related to the progress of the game is stored in the first storage area. The information related to the progress of the game stored in the first storage area includes, for example, the above-described winning information, information related to reel rotation, information related to credit, information related to the game state, and the like. On the other hand, in the present embodiment, information related to fraud is stored in the second storage area. Details regarding fraud stored in the second storage area will be described later.

Next, the sub-board 200 will be described in detail.
As shown in FIG. 2, the sub-board 200 includes a sub-control CPU 200a that performs predetermined processing, a sub-control ROM 200b that stores a control program for the sub-control CPU 200a, and a sub-control that can write and read necessary data. And a control RAM 200c. The sub-board 200 is connected to the effect display device 15, the decorative lamp 13, and the speaker 14. Further, in the sub board 200, random numbers used for various lottery processes are generated. For example, the random number is generated as a hardware random number by providing a random number generation circuit that updates a value every time a clock signal is input, or the sub-control CPU 200a updates the value every predetermined control cycle. By executing the processing, it can be generated as a software random number.

  The sub control ROM 200b stores a sub control program. Further, the sub-control ROM 200b has a display effect pattern that can specify a display effect mode in the effect display device 15, an audio effect pattern that can specify a sound effect mode in the speaker 14, and a light emission effect mode in the decoration lamp 13. Is stored. The sub-control RAM 200c stores various information such as flags relating to the internal state of the slot machine 10. The information stored in the sub control RAM 200c is updated as appropriate during the operation of the slot machine 10.

  The sub board 200 is electrically connected to the main board 100 so that information (control signal) is transmitted from the main board 100 in one direction. Then, the sub control CPU 200a controls the effect display device 15, the decoration lamp 13, and the speaker 14 so as to execute the effect based on various control signals input from the main board 100 (main control CPU 100a). This effect includes, for example, a push order notification effect for notifying the player of the push order of the stop buttons 21a to 21c necessary for deriving and displaying a predetermined symbol combination, and a symbol combination (role for which derivation display is possible) ) Suggestive to the player. Further, the sub-control CPU 200a can also make an effect corresponding to the internal state of the slot machine 10 such as during a bonus game.

Next, the power supply substrate 300 will be described in detail.
The power supply board 300 includes, for example, a power supply circuit 300a that converts the voltage of the power supplied to the slot machine 10 into a voltage that can be used by the main board 100 and the sub board 200 in a game arcade. The power supply board 300 also includes a power-off monitoring circuit 300b that monitors whether the voltage supplied to the slot machine 10 has dropped (decreased) to a predetermined voltage. The power-off monitoring circuit 300b is connected to the power circuit 300a. The predetermined voltage is a minimum voltage necessary for operating the slot machine 10 without affecting the game. Then, the power-off monitoring circuit 300b outputs a power-off signal when the supplied voltage is equal to or lower than a predetermined voltage. The power-off signal output from the power-off monitoring circuit 300b is output to the main board 100 (main control CPU 100a) and the sub board 200 (sub control CPU 200a). Here, the voltage supplied to the slot machine 10 falls below a predetermined voltage, for example, when the power is shut off (power is turned off) or when a power failure occurs. On the contrary, when the power is turned on (power is turned on) or when power is restored, the power is supplied to the slot machine 10, so that the voltage rises and exceeds a predetermined voltage. In the following description, turning on the power of the slot machine 10 is indicated as “power supply is started”, and shutting down the power of the slot machine 10 is indicated as “power supply is cut off”. .

  The power supply board 300 includes a backup power supply 300c made of, for example, an electric double layer capacitor. The main control RAM 100c of the main board 100 and the sub control RAM 200c of the sub board 200 hold stored contents by supplying power from the power supply circuit 300a when power is supplied to the slot machine 10, and supply power. The storage contents are held by supplying power from the backup power source 300c when the operation is not performed. Thereby, the main control RAM 100c and the sub control RAM 200c are configured to be able to retain the stored contents even after the supply of power is cut off.

Next, in the slot machine 10 of the present embodiment, information on fraud stored in the main control RAM 100c will be described together with a specific example.
As shown in FIG. 4, the information related to fraud includes save information for temporarily saving (storing and holding) information related to processing performed by the main control CPU 100a. As will be described in detail later, the save information is information that is rewritten in the second storage area power recovery process executed when the power of the slot machine 10 is recovered. Note that the second storage area power supply recovery process is a process that is executed when the power supply is recovered, and thus can be said to be a process that may be fraudulent. In other words, the save information is information that is rewritten in a process that may be fraudulent, and thus can be said to be important information related to fraud. The save information is stored in a storage area to which a predetermined first address is assigned in the second storage area among the storage areas of the main control RAM 100c. In the following description, a storage area to which each address is assigned is simply referred to as an “address storage area”.

  In addition, in the information relating to fraud of the present embodiment, the opening signal input information indicating whether or not the opening signal indicating that the front door 12 is opened or the front door 12 is opened. There is a door open flag shown. Since the opening signal input information is information related to a state in which fraud is likely to be performed when the front door 12 is opened, it can be said to be important information regarding fraud. The release signal input information is stored in the storage area of the second address predetermined in the second storage area in the storage area of the main control RAM 100c. The door opening flag is a flag indicating that fraud is likely to be performed because the front door 12 is open, and thus can be said to be important information regarding fraud. The door opening flag is stored in the storage area of the third address predetermined in the second storage area in the storage area of the main control RAM 100c.

  In addition, in the information regarding fraud of the present embodiment, operation signal input information indicating whether or not an operation signal indicating that the setting device 26 is operated is input, and that the setting device 26 is operated. There is a setter operation flag to indicate. The operation signal input information can be said to be important information regarding fraud because the operation signal input information is information regarding the setting device 26 in which fraud is likely to be performed because an operation for changing the payout rate directly related to the profit of the player is possible. The operation signal input information is stored in the storage area of the second address predetermined in the second storage area in the storage area of the main control RAM 100c. The operation signal input information is stored in another bit in the storage area of the same second address as the above-described release signal input signal. Further, the setter operation flag is a flag relating to the setter 26 that is likely to be fraudulent because an operation for changing the payout rate directly linked to the profit of the player is possible. I can say that. The setter operation flag is stored in a storage area having a predetermined fourth address in the second storage area in the storage area of the main control RAM 100c.

  As described above, in the present embodiment, at least part of information related to fraud is stored in the second storage area of the main control RAM 100c. In other words, important information regarding fraud is stored in the second storage area.

  In the present embodiment, the first to fourth addresses may be different from the addresses “F200H to F3FFH” of the second storage area, or may be the same address. In addition, when one storage area is shared by a plurality of pieces of information by setting the first to fourth addresses to be the same address, it may be rewritten for each bit associated with each piece of information. In the present specification, the first to fourth numbers of the first to fourth addresses are given for convenience of description, and specify the order of addresses in the storage area of the main control RAM 100c. Not what you want. For example, among the addresses “F200H to F3FFH” in the second storage area, the first to fourth addresses are four addresses that are consecutive in ascending order in the order of the first address → the second address →... → the fourth address. It may be a different address.

  Hereinafter, various processes executed by the main control CPU 100a based on the main control program will be described. First, the game progress process related to the progress of the game will be described. In the present embodiment, the game progress process corresponds to a main routine.

  As shown in FIG. 5, in the game progress process, the main control CPU 100a performs a game start set process (step Sa01). In the game start set process, the main control CPU 100a stores information such as a flag relating to the game state of the slot machine 10 and an effect (so-called freeze effect) using the reel unit 16 in the first storage area of the main control RAM 100c. Alternatively, a process for initializing a predetermined storage area in the first storage area is performed. In the present embodiment, the main control CPU 100a can independently execute the process of initializing the first storage area of the main control RAM 100c and the process of initializing the second storage area. In other words, the first storage area and the second storage area can be initialized independently.

  Next, the main control CPU 100a starts receiving bets for medals (step Sa02). Next, the main control CPU 100a checks the gaming state of the slot machine 10 (step Sa03). In step Sa03, the main control CPU 100a specifies whether or not the gaming state of the slot machine 10 is a bonus game.

  Next, the main control CPU 100a determines whether or not it is a re-game operation time (step Sa04). If it is not during the re-game operation (step Sa04: NO), the main control CPU 100a performs a medal management process for setting the number of bets in the current variable game (step Sa05). In the process of step Sa05, when the medal detection signal is input from the insertion sensor, the main control CPU 100a adds 1 to the bet number stored in the first storage area of the main control RAM 100c. In the process of step Sa05, when the operation signal is input from the bet button 18, the main control CPU 100a adds to the bet number so that the bet number stored in the main control RAM 100c becomes the specified bet number. The credit stored in the first storage area of the main control RAM 100c is subtracted by the added amount.

  The main control CPU 100a determines whether or not the bet number in the current variation game matches the maximum bet number when the re-game operation is being performed (step Sa04: YES) or when the process of step Sa05 is terminated. (Step Sa06). In addition, when the re-game operation is being performed (step Sa04: YES), the main control CPU 100a resets the bet number in the previous variation game as the bet number in the current variation game.

  When the bet number in the current variable game does not match the maximum bet number (step Sa06: NO), the main control CPU 100a proceeds to the process of step Sa03. That is, in the process of step Sa06, the main control CPU 100a determines whether or not it is in a state where a variable game can be started. On the other hand, when the bet number in the current variation game matches the maximum bet number (step Sa06: YES), the main control CPU 100a determines whether or not a start operation by the start lever 20 has been accepted (step Sa07). In the process of step Sa07, the main control CPU 100a makes an affirmative determination when an operation signal is input from the start lever 20, while a negative determination is made when an operation signal is not input from the start lever 20. When the start operation is not accepted (step Sa07: NO), the main control CPU 100a proceeds to the process of step Sa03.

  On the other hand, when the start operation is received (step Sa07: YES), the main control CPU 100a determines the winning information (step Sa08). In step Sa08, the main control CPU 100a determines one winning information by lottery using the value of the winning information determining random number. The processing of step Sa08 is a role lottery (internal lottery) performed internally in the slot machine 10. Further, the main control CPU 100a instructs the start of the variable game in the process of step Sa08 and generates a variable game start command that can specify the determined winning information (symbol combination (combination)). Control to output. In the present embodiment, the role lottery in the process of step Sa08 corresponds to a lottery for determining whether or not to provide a profit. That is, the game progress process includes a process related to a lottery for determining whether or not to give a profit.

  Next, the main control CPU 100a determines whether or not the shortest game time (wait time) has elapsed (step Sa09). When the shortest game time has not elapsed (step Sa09: NO), the main control CPU 100a stands by until the shortest game time has elapsed. When the shortest game time has elapsed (step Sa09: YES), the main control CPU 100a outputs an operation signal (drive signal) to the actuators A1 to A3 to start the rotation of the reels 16a to 16c, thereby changing the game. Is started (step Sa10).

  Subsequently, the main control CPU 100a determines whether or not a stop operation by any one of the stop buttons 21a to 21c has been received (step Sa11). In step Sa11, the main control CPU 100a makes an affirmative determination when an operation signal is input from any one of the stop buttons 21a to 21c, whereas it does not input an operation signal from any one of the stop buttons 21a to 21c. Make a negative decision.

  When the stop operation is received (step Sa11: YES), the main control CPU 100a determines a symbol to be stopped and displayed on the winning line based on the determined winning information and the operation timing of the stop button. The symbol combination control for stopping and displaying the symbol on the winning line is executed (step Sa12).

  When the stop operation has not been received (step Sa11: NO) and when the process of step Sa12 has been completed, the main control CPU 100a determines whether or not all of the reels 16a to 16c have been stopped (step Sa13). . When one or more of the reels 16a to 16c are not stopped (step Sa13: NO), the main control CPU 100a proceeds to the process of step Sa11.

  On the other hand, when all of the reels 16a to 16c are stopped (step Sa13: YES), the main control CPU 100a executes display symbol determination (step Sa14). In the processing of step Sa14, the main control CPU 100a determines whether or not the symbol combination that is stopped and displayed on the active line NL is any symbol combination (combination) that determines a prize in each reel, and the prize. If the symbol combination is determined, the symbol combination is determined. That is, in the process of step Sa14, the main control CPU 100a has won whether or not it has actually won a symbol combination (combination) that can be identified from the winning information determined in the process of step Sa08, and has won a prize. The symbol combination is determined.

  Next, the main control CPU 100a determines whether or not to pay out a medal to the player (step Sa15). In step Sa15, the main control CPU 100a makes an affirmative determination when winning a payout combination, and makes a negative determination when not winning a payout combination. When a medal is paid out (step Sa15: YES), the main control CPU 100a executes a medal payout process for driving the hopper unit and paying out a medal (step Sa16). As described above, in the slot machine 10, medals can be paid out according to the symbol combination stopped and displayed on the active line NL.

  When the medal is not paid out (step Sa15: NO) and when the process of step Sa16 is completed, the main control CPU 100a performs an end process for ending one variation game (step Sa17). That is, in the slot machine 10 of the present embodiment, the game can be ended by the symbol combination being derived and displayed. In the end process of step Sa17, the main control CPU 100a outputs to the sub-board 200 a control for shifting the internal state in accordance with the symbol combination (combination) determined to be a winning or a winning instruction command indicating that the winning is determined. Take control. This winning instruction command causes the sub-board 200 to recognize the winning of the symbol combination (role) specified by the variable game start command. Thereafter, the main control CPU 100a finishes the game progress process related to the execution of one variable game, and proceeds to the process of step Sa01 again.

  As described above, the main control CPU 100a relates to the progress of the game in the game progress process, for example, the winning information determined in the process of step Sa08, the game state of the slot machine 10, and the flag relating to the effect using the reel unit 16. The storage contents of the first storage area are rewritten according to the processing result, for example, information is stored in the first storage area. On the other hand, in principle, the main control CPU 100a does not rewrite the stored contents of the second storage area in the game progress process. In other words, the game progress process of the present embodiment rewrites the storage contents of the first storage area in the storage area of the main control RAM 100c according to the processing result, except for a part of the subroutine processing described later. On the other hand, this is a process that does not rewrite the storage contents of the second storage area.

  Here, in this specification, when simply indicating that “the contents stored in a specific storage area are not rewritten in a specific process”, among the processes included in the “specific process”, the “specific process” is being executed. It is intended not to rewrite the storage contents of the “specific storage area” in accordance with the execution of the process excluding the process (subroutine) called by the user. That is, in this specification, even if it is indicated that “the storage content of a specific storage area is not rewritten in a specific process”, the “specific storage area” in the process called during the execution of the “specific process” There are times when the stored contents of are rewritten. Further, in this specification, when simply indicating “rewriting the storage contents of a specific storage area in a specific process”, it is called during the execution of the “specific process” among the processes included in the “specific process”. It is intended to rewrite the stored contents of the “specific storage area” in accordance with the execution of the process except for the process (subroutine) to be performed.

  Next, the power-off process performed when the main control CPU 100a inputs a power-off signal will be described. That is, the power-off process is a process performed when the power to the slot machine 10 is shut off.

  As shown in FIG. 6, in the power-off process, the main control CPU 100a saves a predetermined register (step Sb01). In the process of step Sb01, the main control CPU 100a stores the stored contents of a predetermined register in the first storage area of the main control RAM 100c.

  Subsequently, the main control CPU 100a stores the interrupt state when the power is turned off in the first storage area of the main control RAM 100c (step Sb02). Here, the interrupt state is a state of whether or not execution of interrupt processing is permitted. Note that the interrupt process of this embodiment is executed at predetermined intervals when the execution of the interrupt process is permitted. In the following description, permitting execution of an interrupt process is simply indicated as “permit interrupt”, and not permitting execution of an interrupt process is simply indicated as “inhibit interrupt”.

  In the process of step Sb02, the main control CPU 100a stores interrupt state information that can specify whether or not an interrupt is permitted when a power-off signal is input in a predetermined register, and then stores the predetermined register. Is stored in the first storage area of the main control RAM 100c.

  Thereafter, the main control CPU 100a saves registers other than the predetermined register (step Sb03). In the process of step Sb03, the main control CPU 100a stores the storage contents of registers other than the predetermined register in the first storage area of the main control RAM 100c. Then, the main control CPU 100a stores a stack pointer in the first storage area of the main control RAM 100c that can specify the address of the stack area in which information (control information) corresponding to the processing result is stored next in the first storage area. Store (step Sb04).

  Thereafter, the main control CPU 100a sets a power-off process completion flag in the first storage area of the main control RAM 100c (step Sb05). In step Sb05, when the processing from step Sb01 to step Sb04 is performed normally, the main control CPU 100a sets a flag that can specify that the processing has been performed normally, while the processing from step Sb01 to step Sb04 is performed. If not performed normally, a flag that can specify that the operation has not been performed normally is set.

  Then, the main control CPU 100a erases the checksum data stored in the first storage area of the main control RAM 100c (step Sb06). Thereafter, the main control CPU 100a calculates a checksum of the main control RAM 100c (step Sb07). In the process of step Sb07, the main control CPU 100a calculates a checksum for all storage areas (all address ranges) of the main control RAM 100c. That is, in the process of step Sb07, the main control CPU 100a calculates the checksum with reference to both the storage contents of the first storage area and the storage contents of the second storage area of the main control RAM 100c.

  Subsequently, the main control CPU 100a stores the checksum value calculated in step Sb07 in the first storage area of the main control RAM 100c as checksum data (step Sb08). Thereafter, the main control CPU 100a prohibits access to the main control RAM 100c (step Sb09). Thereafter, the main control CPU 100a waits until the supply of power is started.

  As described above, the main control CPU 100a rewrites the storage content of the first storage area according to the processing result in the power-off processing. On the other hand, the main control CPU 100a does not rewrite the stored contents of the second storage area in the power-off process. In other words, the power-off process of the present embodiment is a process that rewrites the storage contents of the first storage area in the storage area of the main control RAM 100c according to the processing result, but does not rewrite the storage contents of the second storage area. It is. Further, the main control CPU 100a can refer to both the storage content of the first storage area and the storage content of the second storage area of the main control RAM 100c in the power-off process.

  Next, a power-on process performed by the main control CPU 100a when the supply of power to the slot machine 10 is started will be described. That is, the power-on process is a process performed when the slot machine 10 is powered on. In the present embodiment, the power-on process corresponds to a start process and a first start process.

  As shown in FIG. 7, in the power-on process, the main control CPU 100a sets a stack pointer that can specify the address of the stack area of the first storage area (step Sc01). Subsequently, the main control CPU 100a executes initial setting of the main control CPU 100a (step Sc02).

  Thereafter, the main control CPU 100a performs a second storage area power-on process including determination of whether the front door 12 is opened and determination of whether the setting device 26 is operated (step Sc03). Details of the second storage area power-on process will be described later.

  Subsequently, the main control CPU 100a refers to the storage area of the third address in the second storage area of the main control RAM 100c and determines whether or not the door opening flag is set (there is a door opening flag). Determination is made (step Sc04). When the door opening flag is not set (step Sc04: NO), the main control CPU 100a shifts to a power supply return process for returning to the state of the slot machine 10 when the power is turned off. Details of the power recovery process will be described later.

  On the other hand, when the door opening flag is set (step Sc04: YES), the main control CPU 100a refers to the storage area of the fourth address in the second storage area of the main control RAM 100c, and operates the setter. It is determined whether the flag is set (the setter operation flag is present) (step Sc05). When the setter operation flag is not set (step Sc05: NO), the main control CPU 100a shifts to the power recovery process.

  On the other hand, when the setter operation flag is set (step Sc05: YES), the main control CPU 100a can set the setting information of the slot machine 10 stored in the first storage area of the main control RAM 100c. With reference to (setting value), it is determined whether or not the setting of the slot machine 10 is normal (step Sc06). Here, whether or not the setting of the slot machine 10 is normal is determined based on whether or not the setting stage that can be specified from the setting information is within the range of the setting stage prepared in advance so as to be changeable in the slot machine 10. It can be determined by whether or not.

  When the setting of the slot machine 10 is not normal (step Sc06: NO), the main control CPU 100a sets a predetermined setting as the setting of the slot machine 10 (step Sc07). Specifically, in the present embodiment, setting information that can specify a setting that is least advantageous to the player is stored in the first storage area of the main control RAM 100c.

  When the setting of the slot machine 10 is normal (step Sc06: YES) and when the process of step Sc07 is completed, the main control CPU 100a refers to the storage contents of the first storage area of the main control RAM 100c, and It is determined whether or not the storage contents of one storage area are normal (step Sc08). That is, the power-on process of the present embodiment is a process including checking whether or not the storage contents of the first storage area are normal. If the storage content of the first storage area is not normal (step Sc08: NO), the main control CPU 100a stops the error. Here, the error stop means that various processes are stopped because an unrecoverable error state has occurred.

  On the other hand, when the storage content of the first storage area is normal (step Sc08: YES), the main control CPU 100a initializes a predetermined storage area of the first storage area of the main control RAM 100c (step Sc09). . That is, the power-on process of the present embodiment is a process including initializing the storage contents of the first storage area. Here, “initialization” in this specification is to rewrite the storage area to be initialized to predetermined information (initial information). That is, the initialization is a process for rewriting the stored contents. In the process of step Sc09, the main control CPU 100a does not initialize at least a storage area in the first storage area in which setting information is stored. Thereby, it is possible to suppress the occurrence of a situation in which the setting change due to the operation is not reflected even though the setting device 26 is operated.

  Thereafter, the main control CPU 100a checks whether or not the storage content of the second storage area of the main control RAM 100c is normal, and performs a second storage area check initialization process for initialization (step Sc10). . Details of the second storage area check initialization process will be described later.

  Subsequently, the main control CPU 100a permits an interrupt (step Sc11). Then, the main control CPU 100a performs a setting change process for changing the setting of the slot machine 10 (step Sc12).

  In the setting change process, the main control CPU 100a changes the setting that can be set as the setting of the slot machine 10 step by step every time a predetermined changing operation means is operated. Here, the predetermined change operation means may be an operation means dedicated to setting change, or may be an operation means that is also used as another operation means such as the bet button 18. Then, when a predetermined determination operation means (for example, the start lever 20) is operated, the main control CPU 100a uses the setting selected when the determination operation means is operated as the setting of the slot machine 10. Decide what to do. Thereafter, when the operation of the setting device 26 is completed, the main control CPU 100a stores setting information that can specify the determined setting of the slot machine 10 in the first storage area of the main control RAM 100c, and ends the setting change process. To do. When the setting change process ends, the main control CPU 100a ends the power-on process.

  As described above, the main control CPU 100a rewrites the storage contents of the first storage area according to the processing result in the power-on processing. On the other hand, the main control CPU 100a does not rewrite the stored contents of the second storage area in the power-on process. In other words, the power-on process of the present embodiment is a process in which the storage contents of the first storage area in the storage area of the main control RAM 100c are rewritten according to the processing result, while the storage contents of the second storage area are not rewritten. It is. Further, the main control CPU 100a can refer to both the storage contents of the first storage area and the second storage area of the main control RAM 100c in the power-on process.

  Next, the second storage area power-on process will be described. Since the second storage area power-on process is executed in step Sc03 of the power-on process, it can be grasped as a process (so-called subroutine) called in the power-on process.

  As shown in FIG. 8, in the second storage area power-on process, the main control CPU 100a determines whether or not the front door 12 is opened (step Sd01). In the process of step Sd01, the main control CPU 100a refers to the opening signal input information stored in the storage area of the second address in the second storage area of the main control RAM 100c, and opens the front door 12. It is specified whether or not an open signal indicating that it is being input. When the open signal is input, the main control CPU 100a determines that the front door 12 is open. On the other hand, when the open signal is not input, the front door 12 is open. Judge that there is no. When it is determined that the front door 12 is opened (step Sd01: YES), the main control CPU 100a sets a door open flag in the storage area of the third address in the second storage area of the main control RAM 100c. (Step Sd02).

  When it is determined that the front door 12 is not opened (step Sd01: NO) and when the process of step Sd02 is completed, the main control CPU 100a determines whether or not the setting device 26 is operated (step). Sd03). In the process of step Sd03, the main control CPU 100a operates the setting device 26 with reference to the operation signal input information stored in the storage area of the second address in the second storage area of the main control RAM 100c. It is specified whether or not an operation signal indicating that it is input. When the operation signal is input, the main control CPU 100a determines that the setting device 26 is operated. On the other hand, when the operation signal is not input, the setting device 26 is operated. Judge that there is no. When it is determined that the setter 26 is operated (step Sd03: YES), the main control CPU 100a sets a setter operation flag in the storage area of the fourth address in the second storage area of the main control RAM 100c. (Step Sd04).

  When it is determined that the setting device 26 is not operated (step Sd03: NO), and when the process of step Sd04 is completed, the main control CPU 100a ends the second storage area power-on process.

  As described above, the main control CPU 100a rewrites the storage contents of the second storage area according to the processing result in the second storage area power-on process. On the other hand, the main control CPU 100a does not rewrite the storage contents of the first storage area in the second storage area power-on process. In other words, the second storage area power-on process of the present embodiment rewrites the storage contents of the second storage area in the storage area of the main control RAM 100c according to the processing result, while the storage contents of the first storage area Is a process that does not rewrite.

  Since the second storage area power-on process according to the present embodiment is a process including determining whether or not the front door 12 is opened, it can be grasped as a process related to the open state of the front door 12. That is, the second storage area power-on process corresponds to an open state process. Further, the second storage area power-on process according to the present embodiment is a process including determining whether or not the setting device 26 is operated, and thus can be grasped as processing related to the operation state of the setting device 26. That is, the second storage area power-on process corresponds to an operation state process.

  Next, the second storage area check initialization process will be described. Since the second storage area check initialization process is executed in step Sc10 of the power-on process, it can be grasped as a process (so-called subroutine) called in the power-on process. In the present embodiment, the second storage area check initialization process corresponds to a second start process.

  As shown in FIG. 9, in the second storage area check initialization process, the main control CPU 100a refers to the storage contents of the second storage area of the main control RAM 100c, and the storage contents of the second storage area are normal. Whether or not (step Se01). That is, the second storage area check initialization process of the present embodiment is a process including checking whether the storage contents of the second storage area are normal. When the storage content of the second storage area is not normal (step Se01: NO), the main control CPU 100a stops the error.

  On the other hand, when the storage content of the second storage area is normal (step Se01: YES), the main control CPU 100a initializes a predetermined storage area of the second storage area (step Se02). In other words, the second storage area check initialization process of the present embodiment is a process including initializing the storage contents of the second storage area. Thereafter, the main control CPU 100a ends the second storage area check initialization process.

  As described above, the main control CPU 100a rewrites the storage contents of the second storage area according to the processing result in the second storage area check initialization process. On the other hand, the main control CPU 100a does not rewrite the storage contents of the first storage area in the second storage area check initialization process. In other words, the second storage area check initialization process of the present embodiment rewrites the storage contents of the second storage area in the storage area of the main control RAM 100c according to the processing result, while storing the first storage area. This process does not rewrite the contents.

Next, the power recovery process will be described. In the present embodiment, the power recovery process corresponds to a first process and a first power interruption recovery process.
As shown in FIG. 10, in the power recovery process, the main control CPU 100a calculates the checksum of the main control RAM 100c (step Sf01). In the process of step Sf01, the main control CPU 100a calculates the checksum for all the storage areas of the main control RAM 100c as in the process of step Sb07 in the power-off process.

  Subsequently, the main control CPU 100a determines whether or not the calculated checksum is normal (step Sf02). In step Sf02, the main control CPU 100a compares the checksum calculated in step Sf01 with the checksum stored in the first storage area of the main control RAM 100c in the process of step Sb08 in the power-off process. If they match, it is determined to be normal, while if they do not match, it is determined not to be normal. If the checksum is not normal (step Sf02: NO), the main control CPU 100a stops the error.

  On the other hand, when the checksum is normal (step Sf02: YES), the main control CPU 100a restores the stack pointer (step Sf03). Subsequently, the main control CPU 100a executes a second storage area power return process for determining whether or not the power-off process has been normally performed (step Sf04). Details of the second storage area power recovery process will be described later.

  Thereafter, the main control CPU 100a initializes a storage area excluding the work area and the maximum use area of the stack area in the first storage area of the main control RAM 100c (step Sf05). Subsequently, the main control CPU 100a restores registers other than the predetermined register (step Sf06).

  Thereafter, the main control CPU 100a refers to the interrupt state when the power is turned off (when the supplied voltage becomes equal to or lower than a predetermined voltage), and determines whether or not an interrupt is permitted (step Sf07). In the process of step Sf07, the main control CPU 100a refers to the interrupt status information stored in the first storage area of the main control RAM 100c in step Sb02 of the power-off process, and determines whether or not an interrupt is permitted. judge.

  When the interruption is permitted when the power is turned off (step Sf07: YES), the main control CPU 100a restores the predetermined register (step Sf08). Thereafter, the main control CPU 100a permits an interrupt (step Sf09). Then, the main control CPU 100a ends the power recovery process and returns to the game progress process when the power is turned off. Thereby, it is possible to return to a state in which a game can be performed in a state where interruption is permitted.

  On the other hand, if the interruption is not permitted (prohibited) when the power is turned off (step Sf07: NO), the main control CPU 100a restores the predetermined register in the same manner as in step Sf08 (step Sf10). Then, the main control CPU 100a ends the power recovery process and returns to the game progress process when the power is turned off. Thereby, it is possible to return to a state in which a game can be performed in a state where interruption is not permitted.

  As described above, the main control CPU 100a rewrites the storage content of the first storage area according to the processing result in the power recovery process. On the other hand, the main control CPU 100a does not rewrite the stored contents of the second storage area in the power recovery process. In other words, the power recovery process of the present embodiment is a process of rewriting the storage contents of the first storage area in the storage area of the main control RAM 100c according to the processing result, but not rewriting the storage contents of the second storage area. It is. Further, the main control CPU 100a can refer to both the storage content of the first storage area and the storage content of the second storage area of the main control RAM 100c in the power recovery process.

  Next, the second storage area power supply restoration process will be described. Since the second storage area power recovery process is executed in step Sf04 of the power recovery process, it can be grasped as a process (so-called subroutine) called in the power recovery process. In the present embodiment, the second storage area power recovery process corresponds to a second process and a second power interruption recovery process.

  As shown in FIG. 11, in the second storage area power recovery process, the main control CPU 100a refers to the stack pointer of the first storage area of the main control RAM 100c, and saves the save information that can specify the stack pointer. Of the two storage areas, it is stored (saved) in the storage area of the first address (step Sg01). Subsequently, the main control CPU 100a saves all registers in the stack area of the second storage area (step Sg02).

  Thereafter, the main control CPU 100a refers to the stored contents of the first storage area of the main control RAM 100c, and determines whether or not the power-off processing flag has been set (the power-off processing flag is present) (step S1). Sg03). When the power-off processing completion flag is set (step Sg03: YES), the main control CPU 100a refers to the storage contents of the first storage area of the main control RAM 100c and determines whether or not the stack pointer is normal. Determination is made (step Sg04). Whether or not the stack pointer is normal can be determined based on whether or not the value indicated by the stack pointer is within the address range (numerical value range) defined as the stack area. Note that the process of step Sg04 can also be performed with reference to the save information stored in the storage area of the first address in the second storage area. When the stack pointer is normal (step Sg04: YES), the main control CPU 100a refers to the storage content of the first storage area of the main control RAM 100c and determines whether the setting of the slot machine 10 is normal. (Step Sg05).

  When the setting of the slot machine 10 is normal (step Sg05: YES), the main control CPU 100a restores all registers from the stack area of the second storage area (step Sg06). Subsequently, the main control CPU 100a refers to the storage area of the first address in the second storage area, and restores the saved stack pointer of the first storage area (step Sg07). The process of step Sg07 specifies the process to be restored after the second storage area power supply restoration process based on the stack pointer of the first storage area that can be identified from the save information stored (saved) in the process of step Sg01. However, the stored contents of the first storage area are not rewritten. Thereafter, the main control CPU 100a ends the second storage area power supply recovery process.

  On the other hand, when the power-off processing completed flag is not set (step Sg03: NO), when the stack pointer is not normal (step Sg04: NO), and when the setting of the slot machine 10 is not normal (step Sg05: NO), The main control CPU 100a stops the error. In the present embodiment, when the power-off processing flag is not set, when the stack pointer is not normal, or when the setting of the slot machine 10 is not normal, for example, the stored contents of the main control RAM 100c are invalid. The case where it was rewritten to is considered. Therefore, the second storage area power supply restoration process of the present embodiment can be grasped as a process related to fraud of the slot machine 10.

  As described above, the main control CPU 100a rewrites the storage contents of the second storage area according to the processing result in the second storage area power supply recovery process. On the other hand, the main control CPU 100a does not rewrite the storage contents of the first storage area in the second storage area power recovery process. In other words, the second storage area power recovery process of the present embodiment rewrites the storage contents of the second storage area in the storage area of the main control RAM 100c according to the processing result, while storing the contents of the first storage area. Is a process that does not rewrite. The main control CPU 100a can refer to both the storage contents of the first storage area and the second storage area of the main control RAM 100c in the second storage area power supply recovery process.

Next, the operation of the slot machine 10 configured as described above will be described.
As shown in FIG. 12, the processing that can be executed by the main control CPU 100a according to the present embodiment includes a first type process for rewriting the first storage area and a second type process for rewriting the second storage area. And can be classified. In the present embodiment, the first type process corresponds to the first process, and the second type process corresponds to the second process.

  The first type process of the present embodiment is classified into a game progress process, a power-off process, a power-on process, and a power return process. In addition, the second type storage process of the present embodiment is classified into a second storage area power-on process, a second storage area check initialization process, and a second storage area power supply return process. Thus, the second type process is a process related to fraud.

  The main control CPU 100a of the present embodiment rewrites the storage contents of the second storage area of the main control RAM 100c in the process of rewriting the storage contents of the first storage area of the main control RAM 100c, such as the first type process. Absent. The main control CPU 100a does not rewrite the storage contents of the first storage area of the main control RAM 100c in the process of rewriting the storage contents of the second storage area of the main control RAM 100c, such as the second type process. That is, the main control CPU 100a according to the present embodiment changes the storage area in which the stored contents are rewritten according to the process to be executed.

  In other words, the first storage area can be grasped as a usable (rewritable) usable area for the first type process, while an unusable (unrewritable) unusable area (unrepresented) for the second type process. Use area). Further, the second storage area can be grasped as an unusable area (unused area) that is unusable (unrewritable) for the first type process, while it can be used (rewritable) for the second type process. It can be grasped as an area. That is, the first type process is a process in which information indicating the processing result is stored in the first storage area, while the second type process has an address storing the information indicating the processing result in the second storage area. This is the process.

  Further, the main control CPU 100a of the present embodiment performs both the storage contents of the first storage area and the storage contents of the second storage area in the power-off process, the power-on process, and the power-return process among the first type processes. You can refer to it. That is, in the process of rewriting the storage contents of the first storage area, the main control CPU 100a determines the storage contents of the first storage area based on both the storage contents of the first storage area and the storage contents of the second storage area. Can be rewritten. In addition, the main control CPU 100a can refer to both the storage contents of the first storage area and the storage contents of the second storage area in the second storage area power recovery process among the second type processes. That is, in the process of rewriting the storage contents of the second storage area, the main control CPU 100a determines the storage contents of the second storage area based on both the storage contents of the first storage area and the storage contents of the second storage area. Can be rewritten.

  Also, the main control CPU 100a of the present embodiment uses the save information that can specify the stack pointer of the first storage area and the stored contents of all the registers in the second storage area power recovery process among the second type processes. Store (save) in the second storage area. Then, the main control CPU 100a refers to these stored contents and restores the stack pointer and all registers. For this reason, the main control CPU 100a can suppress rewriting of the stack pointer of the first storage area and the stored contents of all the registers due to fraud during execution of the process of rewriting the storage area of the second storage area.

  Further, the main control CPU 100a of the present embodiment is configured to call and execute another first type process or second type process in the first type process. On the other hand, the main control CPU 100a is configured not to be able to call and execute another second type process or the first type process in the second type process.

Therefore, according to the present embodiment, the following effects can be obtained.
(1) With respect to various processes performed by the main control CPU 100a, the storage area to be rewritten can be made different among the storage areas of the main control RAM 100c for each process, so that the various processes correspond to the storage area to be rewritten. In addition, the storage area of the main control RAM 100c can be easily managed.

  (2) In particular, in the power recovery process that is the first type process, the storage contents of the first storage area are rewritten while the storage contents of the second storage area are not rewritten. Also, in the second storage area power recovery process, which is the second type process called in the power recovery process, the storage contents of the second storage area are rewritten while the storage contents of the first storage area are not rewritten. As described above, by associating the storage area to be rewritten with the first type process and the second type process called by the first type process, it is possible to further easily manage the storage area of the main control RAM 100c.

  (3) In the first type process such as the power-on process and the power return process, the storage contents of the second storage area rewritten in the second type process can be referred to. Therefore, the same process as the second type process is performed in the first type process. There is no need to perform the processing, and the processing of the gaming machine can be made more efficient overall.

  (4) For example, in the power recovery process, the storage contents of the second storage area that are rewritten in the second storage area power recovery process can be referred to. Therefore, the same process as the second storage area power recovery process is performed in the power recovery process. There is no need, and the processing of gaming machines can be made more efficient overall.

  (5) Further, in the power-on process, the storage contents of the second storage area that are rewritten in the second storage area check initialization process can be referred to, so the same process as the second storage area check initialization process is performed. There is no need to perform the above, and the processing of the gaming machine can be made more efficient overall.

  (6) Further, in the power-on process, the storage contents of the second storage area that are rewritten in the second storage area power-on process can be referred to, and therefore the same process as the second storage area power-on process is performed in the power-on process. There is no need, and the processing of gaming machines can be made more efficient overall.

  (7) Specifically, in the second storage area power-on process, it is determined whether or not the front door 12 is opened, and a door opening flag is set in the second storage area. In the power-on process, since the door opening flag of the second storage area set in the second storage area power-on process can be referred to, there is no need to perform a process on whether or not the front door 12 is opened. For this reason, the processing content of the power-on process can be made efficient.

  (8) In the second storage area power-on process, it is determined whether or not the setter 26 is operated, and a setter operation flag is set in the second storage area. In the power-on process, the setting device operation flag of the second storage area set in the second storage area power-on process can be referred to, and therefore it is not necessary to perform the process whether or not the setting device 26 is operated. For this reason, the processing content of the power-on process can be made efficient.

  (9) In the second type process such as the second storage area power recovery process, the storage contents of the first storage area rewritten in the first type process can be referred to. There is no need to perform seed processing, and the processing of gaming machines can be made more efficient overall.

  (10) For example, in the second storage area power recovery process, the storage contents of the first storage area that are rewritten in the power recovery process can be referred to, so the same process as the power recovery process is performed in the second storage area power recovery process. There is no need, and the processing of gaming machines can be made more efficient overall.

  (11) The power recovery process and the second storage area power recovery process are processes that are performed when the slot machine 10 recovers. In the present embodiment, since the storage areas to be rewritten are different from each other for the power restoration process and the second storage area power restoration process, which are such important processes, the mixing of unnecessary storage contents is suppressed, Security can be improved.

  (12) In the second storage area power recovery process, the save information that can specify the stack pointer of the first storage area and the storage contents of all registers are saved to the second storage area. It is possible to prevent the stored contents of the stack pointer and all registers from being rewritten. Therefore, it is possible to suppress the mixing of unnecessary stored contents and further improve the security.

  (13) In the second storage area power supply restoration process, which is a process related to fraud of the slot machine 10, the storage contents of the second storage area are rewritten. In other words, information related to fraud is stored in the second storage area. According to this, since the content stored in each storage area can be given regularity, the management of the storage area of the main control RAM 100c can be further facilitated.

  (14) The power-on process and the second storage area check initialization process are processes that are performed when the power of the slot machine 10 is turned on. In this embodiment, since the storage areas to be rewritten are different from each other for the power-on process and the second storage area check initialization process, which are such important processes, mixing of unnecessary storage contents is suppressed. , Security can be improved.

  (15) The power-on process includes initializing the storage contents of the first storage area, and the second storage area check initialization process includes initializing the storage contents of the second storage area. As a result, each process can be associated with a storage area to be initialized, and management of the storage area of the main control RAM 100c can be further facilitated.

  (16) The power-on process includes checking whether or not the storage contents of the first storage area are normal, and the second storage area check initialization process is that the storage contents of the second storage area are normal Including checking whether or not. As a result, each process can be associated with a storage area to be checked for stored contents, and management of the storage area of the main control RAM 100c can be further facilitated.

  (17) The second storage area power-on process is a process including determining whether or not the front door 12 is opened, and is therefore an important process regarding fraud performed by opening the front door 12. I can say that. In this embodiment, the second storage area power-on process, which is such an important process, is performed as a subroutine of the power-on process, and is not the first storage area rewritten by the power-on process, but the first storage area. The storage contents of the second storage area different from the storage area are rewritten. For this reason, management of the storage area of the main control RAM 100c can be further facilitated, and mixing of unnecessary storage contents can be suppressed to improve security.

  (18) Further, since the second storage area power-on process is a process including determining whether or not the setting device 26 capable of changing the setting of the slot machine 10 is operated, fraud is likely to be performed. It can be said that this is an important process related to the setting device 26. In this embodiment, the second storage area power-on process, which is such an important process, is performed as a subroutine of the power-on process, and is not the first storage area rewritten by the power-on process, but the first storage area. The storage contents of the second storage area different from the storage area are rewritten. For this reason, management of the storage area of the main control RAM 100c can be further facilitated, and mixing of unnecessary storage contents can be suppressed to improve security.

In addition, you may change the said embodiment as follows.
In the storage area of the main control RAM 100c, how to define the first storage area and the second storage area may be changed as appropriate. For example, the second storage area may be a storage area assigned to an address before the first storage area. Moreover, it is not necessary to set an unused area in each storage area. In other words, the rewriteable storage area and the non-rewritable storage area need only be different for each type of processing performed by the main control CPU 100a.

  The first storage area and the second storage area may not be storage areas in the same RAM provided on the same substrate, for example, storage areas in another RAM provided on the same substrate. Alternatively, it may be a storage area in another RAM provided on another substrate. In this case, both of the plurality of RAMs correspond to the storage unit.

  The storage content stored in the first storage area and the storage content stored in the second storage area may be changed as appropriate. For example, information regarding fraud may be stored in the first storage area, or information regarding the progress of the game may be stored in the second storage area. However, from the viewpoint of facilitating the management of the storage area of the main control RAM 100c, it is preferable to classify information by type and to store different storage areas according to the type of information. Note that the types of information include information related to reel control, information related to effects, and the like in addition to information related to game progress and information related to fraud described in the above embodiment.

  In addition to the first type process and the second type process, the main control CPU 100a performs the third type process that does not rewrite both the storage contents of the first storage area and the storage contents of the second storage area of the main control RAM 100c. You may go. In such a third type process, both the storage contents of the first storage area and the storage contents of the second storage area may be referred to. In this case, in the third type process, since both the storage contents of the first storage area and the storage contents of the second storage area can be referred to, the management of the storage unit is facilitated, and further the processing of the gaming machine is totally performed. Increase efficiency. Further, the main control CPU 100a may refer to only one of the storage contents of the first storage area and the storage contents of the second storage area in the third type process, or may not refer to any of them. Also good. As the third type process, for example, at least one of the storage contents of the first storage area and the storage contents of the second storage area is referred to, and a different subroutine is called and executed based on the referred result. Processing can be assumed. In addition, as the third type process, for example, a predetermined subroutine is called in a predetermined order for the third type process without referring to the stored contents of the first storage area and the stored contents of the second storage area. Can be executed.

  In the above embodiment, the main control CPU 100a is different from the storage area to be rewritten in part of the process of rewriting either the storage content of the first storage area or the storage content of the second storage area. Although the storage contents of the storage area can be referred to, the present invention is not limited to this. For example, in all processes of rewriting one of the storage contents of the first storage area and the storage contents of the second storage area, the storage contents of a storage area different from the storage area to be rewritten by the process can be referred to Also good. According to this, it is not necessary to perform the same process as the process of rewriting the storage contents of the predetermined storage area in the process of rewriting the storage area different from the predetermined storage area, and the processing of the slot machine 10 is improved overall. it can.

  In addition, in all of the processes for rewriting one of the storage contents of the first storage area and the storage contents of the second storage area, the storage contents of a storage area different from the storage area to be rewritten by the process cannot be referred to. May be. In addition, in the process of rewriting the storage contents of the first storage area, the storage contents of the second storage area can be referred to, while in the process of rewriting the storage contents of the second storage area, the storage contents of the first storage area cannot be referred to. It may be. In addition, in the process of rewriting the storage contents of the second storage area, the storage contents of the first storage area can be referred to, while in the process of rewriting the storage contents of the first storage area, the storage contents of the second storage area cannot be referred to. It may be.

  Specifically, the storage content of the first storage area may be referred to in the second storage area check initialization process (second type process). In the second storage area power-on process (second type process), the storage contents of the first storage area may be referred to. Further, in the game progress process (first type process) related to the progress of the game, the stored contents of the second storage area may be referred to.

  The process performed by the main control CPU 100a may include a process of rewriting both the storage contents of the first storage area and the storage contents of the second storage area. That is, the processing performed by the main control CPU 100a includes at least rewriting the storage contents of the first storage area while not rewriting the storage contents of the second storage area, and rewriting the storage contents of the second storage area. It is only necessary to include a process that does not rewrite the storage contents of the storage area, and it may further include other processes.

  The main control CPU 100a saves the storage contents of the first storage area to the second storage area so that the storage contents of the first storage area are not rewritten in the second storage area power recovery process. The contents may be saved in the storage area, or the stored contents may not be saved. Further, the storage contents of the first storage area may be saved so that the storage contents of the first storage area are not rewritten in all the processes for rewriting the storage contents of the second storage area. According to this, it is possible to prevent the storage contents of the first storage area from being rewritten unintentionally due to fraud, etc., even though the process of not rewriting the storage contents of the first storage area is performed. Further, the main control CPU 100a may save the storage contents of the second storage area so that the storage contents of the second storage area are not rewritten in the process of rewriting the storage contents of the first storage area.

  The processing procedures in various processes performed by the main control CPU 100a may be changed as appropriate. That is, in the processing performed by the main control CPU 100a, the storage content of the first storage area of the main control RAM 100c is rewritten while the storage content of the second storage area is not rewritten, and the storage content of the second storage area is rewritten. On the other hand, it is only necessary to include at least processing that does not rewrite the storage contents of the first storage area.

  For example, if it is determined in step Se01 of the second storage area check initialization process executed in step Sc10 of the power-on process that the storage content of the second storage area is not normal, the second storage area After the error flag is set, the second storage area check initialization process may be terminated. In this case, after the second storage area check initialization process is finished, when returning to the power-on process, it is determined whether or not the error flag is set. If the error flag is set, the error is stopped. If the error flag is not set, the process may proceed to the next process (step Sc11).

  In addition, when a negative determination is made in the processing of steps Sg03 to Sg05 of the second storage area power recovery process executed in step Sf04 of the power recovery process, an error flag is set in the second storage area, and then 2 The storage area power supply restoration process may be terminated. In this case, after the second storage area power restoration process is completed, when the process returns to the power restoration process, it is determined whether or not an error flag is set. If the error flag is set, the error is stopped. If the error flag is not set, the process may proceed to the next process (step Sf05).

  Any of the process for restoring all registers in the second storage area power supply restoration process executed in step Sf04 of the power restoration process (step Sg06) and the process for restoring the stack pointer of the first storage area (step Sg07) Either or both of the processes may be executed in the power recovery process. That is, in the second storage area power recovery process, if the determination in step Sg05 is affirmative, the second storage area power recovery process is terminated, and in the subsequent power recovery process, all registers are recovered and the first storage area A process for restoring the stack pointer may be executed.

The main control CPU 100a may be configured to call and execute another second type process or the first type process in the second type process.
-You may change suitably the number of processes classified into a 1st type process and a 2nd type process. For example, the number of processes classified as the first type process may be one, and the number of processes classified as the second type process may be plural. Further, the number of processes classified as the first type process may be plural, and the number of processes classified as the second type process may be one. Further, both the number of processes classified as the first type process and the number of processes classified as the second type process may be one. In addition, the number of processes classified as the first type process and the number of processes classified as the second type process may both be plural. In this case, the number of processes classified as the first type process and the The number of processes classified into two types of processes may be different.

  An interrupt process may be adopted as the first type process or the second type process. Further, an interrupt process may be employed as the first type process, and a process called by the interrupt process (interrupt process subroutine) may be employed as the second type process.

  The main control ROM 100b stores and holds the specific storage area in the second storage area for the process of rewriting the first storage area of the main control RAM 100c among the various processes performed by the main control CPU 100a. As for the process of rewriting, it may be configured to store and hold in a non-specific storage area different from the specific storage area. In other words, of the storage areas of the main control RAM 100c, the first storage area is a storage area that is rewritten by processing stored and held in a specific storage area of the main control ROM 100b, and the second storage area is It can be grasped as a storage area that is rewritten by processing stored and held in a non-specific storage area of the main control ROM 100b.

  In addition, in the process stored in the specific storage area of the main control ROM 100b, another process stored in the specific storage area or the process stored in the non-specific storage area is called and executed. You may be able to. Further, in the process stored in the non-specific storage area of the main control ROM 100b, the process stored in the specific storage area may not be called and executed. Further, in the process stored in the non-specific storage area of the main control ROM 100b, another process stored in the non-specific storage area may be called and executed. It may be.

  The main control ROM 100b and the main control RAM 100c may be different memories or may be different storage areas in the same memory. Similarly, the sub control ROM 200b and the sub control RAM 200c may be different memories or may be different storage areas in the same memory.

  The backup power supply 300c of the power supply board 300 can supply power to the main control RAM 100c of the main board 100, while it cannot be supplied to the sub control RAM 200c of the sub board 200. Good. That is, the sub control RAM 200c may be configured so that the stored contents cannot be retained when the power is shut off.

  -The function of the sub-board 200 may be divided into a plurality of boards. For example, a display board that specially controls the effect display device 15, an audio board that specially controls the speaker 14, and a lamp board that specially controls the decorative lamp 13 may be provided. An integrated board may be further provided.

  The slot machine 10 may include a RAM clear switch for deleting (clearing) the stored contents of the main control RAM 100c in addition to or instead of the setting device 26. In this case, the main control CPU 100a may execute the processes of steps Sc09 and Sc10 when the RAM clear switch is operated in the power-on process shown in FIG.

  -You may actualize to the game machine using the game medium of a shape different from a medal. For example, the present invention may be embodied as a slot machine (so-called parrot) using a game ball (pachinko ball) as a game medium or a pachinko game machine. When embodied in a pachinko gaming machine, for example, a RAM clear switch for erasing (clearing) the stored contents of the main control RAM 100c may be provided as an operable operation unit instead of the setting device 26. At this time, the RAM clear switch may be disposed on the back side of the front door (airframe), like the setting device 26. Then, the main control CPU 100a may rewrite the storage contents of the second storage area while not rewriting the storage contents of the first storage area in the process related to the operation state of the RAM clear switch. Since the RAM clear switch is an operation unit capable of rewriting the stored contents of the main control RAM 100c, the RAM clear switch is likely to be an unauthorized target. For this reason, the process regarding the operation state of the RAM clear switch can be grasped as an important process regarding fraud. Information rewritten in the process related to the operation state of the RAM clear switch can be grasped as information related to fraud.
