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 drops below the predetermined voltage, for example, when the power is turned off (power is turned off) or at the time of a power failure. Conversely, when the power is turned on (the power is turned on) or when the power is restored, the power is supplied to the slot machine 10, so that the voltage rises to a voltage exceeding a predetermined voltage. In the following description, turning on the power of the slot machine 10 is referred to as “power supply is started”, and turning off 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 composed of, for example, an electric double layer capacitor. When the power is supplied to the slot machine 10, the main control RAM 100c of the main board 100 and the sub control RAM 200c of the sub board 200 retain the stored contents by the power supply from the power supply circuit 300a and supply the power. Is not performed, the stored contents are retained by the power supply from the backup power supply 300c. Thus, the main control RAM 100c and the sub control RAM 200c are configured to be able to retain the stored contents even after the power supply 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 with a specific example.
As shown in FIG. 4, the information on impropriety includes evacuation information for temporarily evacuation (storage holding) of information on processing performed by the main control CPU 100a. As will be described later in detail, the evacuation information is information that is rewritten in the second storage area power restoration process executed when the power of the slot machine 10 is restored. Note that the second storage area power return process is a process that is executed when the power is restored, and thus can be said to be a process in which there is a possibility that an illegal operation may be performed. In other words, the evacuation information is information that can be rewritten in a process in which there is a possibility that fraud is performed, and thus can be said to be important information regarding fraud. The evacuation information is stored in a storage area of the main control RAM 100c to which a predetermined first address is allocated in the second storage area. In the following description, the storage area to which each address is assigned is simply referred to as “address storage area”.

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

  In addition, the information related to impropriety of the present embodiment includes operation signal input information indicating whether or not an operation signal indicating that the setting device 26 is being operated and information indicating that the setting device 26 is being operated. There is a setting device operation flag shown. The operation signal input information is important information relating to fraud because it is information relating to the setting device 26 in which fraud is likely to be performed because an operation for changing a payout rate directly related to the profit of the player is possible. The operation signal input information is stored in a storage area of a predetermined second address 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 opening signal input signal. Further, since the setting device operation flag is a flag relating to the setting device 26 where fraud is likely to be performed because an operation of changing a payout rate directly related to the profit of the player is possible, it is important information regarding fraud. I can say. The setting device operation flag is stored in a storage area of 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 a part of the information on 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 addresses or the same address among the addresses “F200H to F3FFH” of the second storage area. 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, the information may be rewritten for each bit associated with each piece of information. In this 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. It does not do. For example, among the addresses “F200H to F3FFH” of the second storage area, the first to fourth addresses are four addresses consecutive in ascending order in the order of first address → second address →... → fourth address. Or 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 processing related to the progress of the game will be described. In the present embodiment, the game progress processing corresponds to a main routine.

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

  Next, the main control CPU 100a starts accepting medals bet (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 a replay operation is being performed (step Sa04). When it is not during the replaying operation (step Sa04: NO), the main control CPU 100a performs a medal management process for setting the bet number in the current fluctuation 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. Further, in the processing of step Sa05, when the operation signal is input from the bet button 18, the main control CPU 100a adds the bet number stored in the main control RAM 100c to the specified bet number and adds the bet number to the bet number. The credits stored in the first storage area of the main control RAM 100c are subtracted by the added amount.

  The main control CPU 100a determines whether or not the bet number in the current fluctuating game matches the maximum bet number when the replay operation is being performed (step Sa04: YES) or when the processing in step Sa05 is completed. (Step Sa06). When the replaying operation is being performed (step Sa04: YES), the main control CPU 100a resets the bet number in the previous fluctuation game as the bet number in the current fluctuation game.

  If the bet number in the current fluctuation game does not match the maximum bet number (step Sa06: NO), the main control CPU 100a proceeds to the processing 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 in which the fluctuating game can be started. On the other hand, when the bet number in the current fluctuation 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 received (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 making a negative determination when an operation signal is not input from the start lever 20. If the start operation has not been received (step Sa07: NO), the main control CPU 100a proceeds to the processing of step Sa03.

  On the other hand, when the start operation has been received (step Sa07: YES), the main control CPU 100a determines winning information (step Sa08). In step Sa08, the main control CPU 100a determines one piece of winning information by lottery using the value of the random number for determining winning information. The process of step Sa08 is a combination lottery (internal lottery) performed internally in the slot machine 10. In the process of step Sa08, the main control CPU 100a instructs the start of the variable game and generates a variable game start command capable of specifying the determined winning information (symbol combination (role)). Perform output control. In the present embodiment, the winning lottery in the processing of step Sa08 corresponds to a lottery for determining whether or not to give a profit. That is, the game progress processing includes a processing relating to a lottery as to 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 waits until the shortest game time elapses. 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 each of the reels 16a to 16c, and the fluctuation game Is started (step Sa10).

  Subsequently, the main control CPU 100a determines whether 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 of the stop buttons 21a to 21c, and when an operation signal is not input from any of the stop buttons 21a to 21c. Make a negative decision.

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

  When the stop operation has not been received (step Sa11: NO) and when the processing 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). . If one or more of the reels 16a to 16c has not been stopped (step Sa13: NO), the main control CPU 100a proceeds to the processing of step Sa11.

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

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

  When not paying out medals (step Sa15: NO) and when ending the processing of step Sa16, the main control CPU 100a performs end processing for ending one fluctuation game (step Sa17). That is, in the slot machine 10 of the present embodiment, the game can be terminated by displaying the symbol combination. In the termination process of step Sa17, the main control CPU 100a outputs to the sub-board 200 a control for shifting the internal state according to the symbol combination (combination) determined to be a winning, and a winning instruction command indicating that the winning has been determined. Perform control. The winning instruction command causes the sub-board 200 to recognize the winning of the symbol combination (combination) specified by the variable game start command. After that, the main control CPU 100a ends the game progress processing related to the execution of the one variation game, and shifts to the processing of step Sa01 again.

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

  Here, in the present specification, when it is simply indicated that “the storage content of a specific storage area is 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 processing excluding the processing (subroutine) called by (1). That is, in the present specification, even if it is indicated that “the storage content of a specific storage area is not rewritten in a specific processing”, the “specific storage area” is called in the processing called during the execution of the “specific processing”. May be rewritten. Further, in this specification, when simply indicating “rewriting the storage content of a specific storage area in a specific process”, among the processes included in the “specific process”, the process is called during the execution of the “specific process”. It is intended to rewrite the storage contents of the “specific storage area” with the execution of the processing excluding the processing (subroutine) to be performed.

  Next, a power-off process performed when the main control CPU 100a receives a power-off signal will be described. That is, the power-off process is a process performed when the power of the slot machine 10 is cut 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 storage contents of the predetermined register in the first storage area of the main control RAM 100c.

  Subsequently, the main control CPU 100a stores the interrupt state at the time of power-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 the interrupt processing is permitted. The interrupt process according to the present embodiment is executed at predetermined intervals when execution of the interrupt process is permitted. In the following description, permitting the execution of the interrupt process is simply referred to as “permitting the interrupt”, and not permitting the execution of the interrupt process is simply referred to as “prohibiting the interrupt”.

  In the process of step Sb02, the main control CPU 100a stores in a predetermined register interrupt state information capable of specifying whether or not an interrupt is permitted when the power-off signal is input, 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 the registers other than the predetermined register in the first storage area of the main control RAM 100c. Then, the main control CPU 100a stores, in the first storage area, a stack pointer capable of specifying an address of a stack area in which information (control information) corresponding to the processing result is stored next in the first storage area of the main control RAM 100c. It is stored (step Sb04).

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

  Then, the main control CPU 100a deletes 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 content of the first storage area and the storage content 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 as checksum data in the first storage area of the main control RAM 100c (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 power supply is started.

  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-off processing. On the other hand, the main control CPU 100a does not rewrite the storage contents of the second storage area in the power-off processing. In other words, the power-off process of the present embodiment is a process of rewriting the storage content of the first storage region in the storage region of the main control RAM 100c according to the processing result, but not rewriting the storage content of the second storage region. 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 processing.

  Next, a power-on process performed by the main control CPU 100a when power supply to the slot machine 10 is started will be described. That is, the power-on process is a process performed when the power of the slot machine 10 is turned 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 capable of specifying the address of the stack area of the first storage area (step Sc01). Subsequently, the main control CPU 100a performs an 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 a determination as to whether or not the front door 12 is open and a determination as to whether or not the setting device 26 has been operated (step Sc03). The second storage area power-on processing will be described later in detail.

  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 open flag is set (the door open flag is present). A determination is made (step Sc04). When the door open flag is not set (step Sc04: NO), the main control CPU 100a shifts to a power return process for returning to the state of the slot machine 10 when the power is turned off. The power return process will be described later in detail.

  On the other hand, when the door open 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 setting device. It is determined whether the flag is set (the setting device operation flag is present) (step Sc05). If the setting device operation flag is not set (step Sc05: NO), the main control CPU 100a proceeds to a power return process.

  On the other hand, if the setting device operation flag is set (step Sc05: YES), the main control CPU 100a sets the slot machine 10 setting information stored in the first storage area of the main control RAM 100c. With reference to (setting value), it is determined whether the setting of the slot machine 10 is normal (step Sc06). Here, it is determined whether the setting of the slot machine 10 is normal or not by determining whether the setting stage identifiable from the setting information is within the range of the setting stage prepared so as to be changeable in advance 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, the setting information capable of specifying the 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 content of the first storage area of the main control RAM 100c, It is determined whether the storage content of one storage area is normal (step Sc08). That is, the power-on process according to the present embodiment is a process including checking whether the storage content of the first storage area is 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 term “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 in 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 means rewriting the storage area to be initialized to predetermined information (initial information). That is, the initialization is a process of rewriting the stored contents. In the process of step Sc09, the main control CPU 100a does not initialize at least the storage area of the first storage area in which the setting information is stored. Accordingly, it is possible to suppress a situation in which the setting change by 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). . The second storage area check initialization processing will be described later in detail.

  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 settings of the slot machine 10 (Step Sc12).

  In the setting change processing, the main control CPU 100a changes the setting that can be set as the setting of the slot machine 10 by one step each time a predetermined change operation unit is operated. Here, the predetermined change operation means may be an operation means dedicated to setting change, or may be an operation means shared with other operation means such as, for example, the bet button 18. Then, when a predetermined determination operation means (for example, the start lever 20 or the like) is operated, the main control CPU 100a changes the setting selected when the determination operation means is operated to the setting of the slot machine 10. Decide to do it. Thereafter, when the operation of the setting device 26 is completed, the main control CPU 100a stores setting information capable of specifying 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. I do. When the setting change process ends, the main control CPU 100a ends the power-on process.

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

  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 called in the power-on process (a so-called subroutine).

  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 open (step Sd01). In the process of step Sd01, the main control CPU 100a opens the front door 12 with reference to the open signal input information stored in the second address storage area of the second control area of the main control RAM 100c. It specifies whether or not an open signal indicating that the operation is being performed is input. The main control CPU 100a determines that the front door 12 is open when the open signal is input, and determines that the front door 12 is open when the open signal is not input. It is determined that there is not. When it is determined that the front door 12 is open (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 has not been opened (step Sd01: NO), and when the processing of step Sd02 has been completed, the main control CPU 100a determines whether or not the setting device 26 has been operated (step Sd01). Sd03). In the process of step Sd03, the main control CPU 100a operates the setting unit 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 specifies whether or not an operation signal indicating that the operation has been performed is input. The main control CPU 100a determines that the setting device 26 has been operated when an operation signal has been input, while the setting device 26 has been operated when no operation signal has been input. It is determined that there is not. When it is determined that the setting device 26 has been operated (step Sd03: YES), the main control CPU 100a sets the setting device operation flag in the storage region of the fourth address in the second storage region of the main control RAM 100c. (Step Sd04).

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

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

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

  Next, the second storage area check initialization processing 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 called a power-on process (a so-called subroutine). In the present embodiment, the second storage area check initialization processing corresponds to a second start processing.

  As shown in FIG. 9, in the second storage area check initialization processing, the main control CPU 100a refers to the storage content of the second storage area of the main control RAM 100c, and the storage content of the second storage area is normal. It is determined whether or not (Step Se01). That is, the second storage area check initialization process according to the present embodiment is a process including checking whether or not the storage content of the second storage area is normal. If 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 in the second storage area (Step Se02). That is, the second storage area check initialization process according to 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 processing.

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

Next, the power return process will be described. In the present embodiment, the power restoration process corresponds to a first process and a first power interruption restoration process.
As shown in FIG. 10, in the power return process, the main control CPU 100a calculates a checksum of the main control RAM 100c (step Sf01). In the process of step Sf01, the main control CPU 100a calculates a checksum for all 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 step Sb08 in the power-off process. If they match, it is determined that they are normal, while if they do not match, it is determined that they are not normal. If the checksum is not normal (step Sf02: NO), the main control CPU 100a stops the error.

  On the other hand, if 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 shutdown process has been performed normally (step Sf04). The second storage area power return process will be described later in detail.

  After that, the main control CPU 100a initializes a storage area of the first storage area of the main control RAM 100c other than the maximum use area of the work area and the stack area (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 lower than or equal to a predetermined voltage), and determines whether or not the interrupt is permitted (step Sf07). In the process of step Sf07, the main control CPU 100a refers to the interrupt state 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 the interrupt is permitted. judge.

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

  On the other hand, when the interruption is not permitted (prohibited) when the power is turned off (step Sf07: NO), the main control CPU 100a restores a predetermined register as in step Sf08 (step Sf10). Then, the main control CPU 100a ends the power return process, and returns to the game progress process when the power is turned off. As a result, it is possible to return to a state where a game can be played 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 return processing. On the other hand, the main control CPU 100a does not rewrite the storage contents of the second storage area in the power return process. In other words, the power restoration process according to the present embodiment is a process of rewriting the storage content of the first storage region in the storage region of the main control RAM 100c according to the processing result, but not rewriting the storage content of the second storage region. It is. Further, 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 of the main control RAM 100c in the power return process.

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

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

  Thereafter, the main control CPU 100a refers to the storage content of the first storage area of the main control RAM 100c, and determines whether or not the power-off processing completion flag is set (the power-off processing completion flag is present) (step). Sg03). When the power-off processing completed flag is set (step Sg03: 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 stack pointer is normal. A determination is made (step Sg04). Whether the stack pointer is normal or not can be determined based on whether or not the value indicated by the stack pointer is within the address range (numeric range) defined as the stack area. The processing in step Sg04 can also be performed with reference to the save information stored in the storage area at the first address in the second storage area. If 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).

  If 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 stack pointer of the saved first storage area (step Sg07). The process of step Sg07 specifies a process to return after the second storage region power supply return process based on the stack pointer of the first storage region that can be specified from the save information stored (evacuated) in the process of step Sg01. It does not rewrite the storage contents of the first storage area. Thereafter, the main control CPU 100a ends the second storage area power supply return processing.

  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, the case where the power-off processing completed flag is not set, the case where the stack pointer is not normal, and the case where the setting of the slot machine 10 is not normal are, for example, cases where the storage content of the main control RAM 100c is invalid. For example, it may be considered that the information is rewritten. Therefore, the second storage area power return process of the present embodiment can be grasped as a process related to improper operation of the slot machine 10.

  As described above, in the second storage area power return process, the main control CPU 100a rewrites the storage contents of the second storage area according to the processing result. 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 supply return processing. In other words, in the second storage area power restoration process of the present embodiment, while the storage content of the second storage area in the storage area of the main control RAM 100c is rewritten according to the processing result, the storage content of the first storage area Is not rewritten. Further, 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 of the main control RAM 100c in the second storage area power return process.

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

  The first type processing of the present embodiment is classified into a game progress processing, a power-off processing, a power-on processing, and a power-return processing. Further, the second type processing of the present embodiment is classified into a second storage area power-on processing, a second storage area check initialization processing, and a second storage area power return processing. As described above, each of the second type processes is a process related to fraud.

  The main control CPU 100a of the present embodiment rewrites the storage content of the second storage area of the main control RAM 100c in the process of rewriting the storage content of the first storage area of the main control RAM 100c, such as the first type processing. 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 processing of rewriting the storage contents of the second storage area of the main control RAM 100c, such as the second type processing. That is, the main control CPU 100a of the present embodiment changes the storage area in which the stored content is rewritten according to the processing to be executed.

  In other words, the first storage area can be grasped as a usable (rewritable) use area for the type 1 processing, while an unusable (non-rewritable) non-use area (not available) for the type 2 processing. Usage area). In addition, the second storage area can be recognized as an unusable (unrewritable) non-use area (unused area) for the type 1 processing, but is usable (rewriteable) for the type 2 processing. Can be grasped as an area. That is, the first type process is a process in which an address for storing information indicating the processing result is in the first storage area, whereas the second type process is an address in which the address for storing the information indicating the processing result is in the second storage area. This is the process in

  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 processing, the power-on processing, and the power-return processing among the first-type processing. Can be referenced. That is, in the process of rewriting the storage content of the first storage area, the main control CPU 100a changes the storage content of the first storage area based on both the storage content of the first storage area and the storage content 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 return processing in the second type processing. That is, in the process of rewriting the storage content of the second storage area, the main control CPU 100a changes the storage content of the second storage area based on both the storage content of the first storage area and the storage content of the second storage area. Can be rewritten.

  Further, in the second storage area power restoration processing of the second type processing, the main control CPU 100a of the present embodiment stores evacuation information capable of specifying the stack pointer of the first storage area and storage contents of all registers. It is stored (evacuated) in the second storage area. Then, the main control CPU 100a restores the stack pointer and all registers with reference to these stored contents. Therefore, the main control CPU 100a can prevent the stack pointer of the first storage area and the storage contents of all the registers from being rewritten due to fraud or the like during execution of the processing of rewriting the storage area of the second storage area.

  Further, the main control CPU 100a of the present embodiment is configured to be able to call and execute another type 1 process or type 2 process in the type 1 process. On the other hand, the main control CPU 100a is configured so that it cannot call and execute another type 2 process or type 1 process in the type 2 process.

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

  (2) In particular, in the power restoration process as the first type process, the storage content of the first storage area is rewritten while the storage content of the second storage area is not rewritten. Further, in the second storage area power supply return processing, which is the second type processing called in the power supply return processing, the storage contents of the second storage area are rewritten while the storage contents of the first storage area are not rewritten. In this way, by associating the storage areas to be rewritten in the type 1 processing with the type 2 processing called by the type 1 processing, the management of the storage area of the main control RAM 100c can be further facilitated.

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

  (5) In the power-on processing, since the storage contents of the second storage area rewritten in the second storage area check initialization processing can be referred to, the same processing as the second storage area check initialization processing is performed. And the processing of the gaming machine can be made more efficient overall.

  (6) Further, in the power-on processing, since the stored contents of the second storage area rewritten in the second storage area power-on processing can be referred to, the same processing as the second storage area power-on processing is performed in the power-on processing. There is no need for this, and the processing of the gaming machine 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 open, and a door open flag is set in the second storage area. In the power-on process, the door open flag of the second storage area set in the second storage area power-on process can be referred to, so that it is not necessary to perform the process of determining whether the front door 12 is open. Therefore, the processing content of the power-on processing can be made more efficient.

  (8) In the second storage area power-on processing, it is determined whether or not the setting device 26 is operated, and a setting device operation flag is set in the second storage region. In the power-on process, the setting device operation flag of the second storage area set in the second storage region power-on process can be referred to, so that it is not necessary to perform the process of determining whether the setting device 26 is operated. Therefore, the processing content of the power-on processing can be made more efficient.

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

  (10) For example, in the second storage area power return processing, since the stored contents of the first storage area which is rewritten in the power return processing can be referred to, the same processing as the power return processing is performed in the second storage area power return processing. There is no need for this, and the processing of the gaming machine can be made more efficient overall.

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

  (12) In the second storage area power restoration process, in order to save the save information that can specify the stack pointer of the first storage area and the storage contents of all registers in the second storage area, the first storage area is illegally stored. Rewriting of the contents stored in the stack pointer and all registers can be suppressed. Therefore, mixing of unnecessary storage contents can be suppressed, and security can be further improved.

  (13) In the second storage area power return processing which is processing relating to fraud of the slot machine 10, the storage contents of the second storage area are rewritten. In other words, the second storage area is configured to store information on fraud. 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) Since the power-on process and the second storage area check initialization process are performed when the power of the slot machine 10 is turned on, it can be said that the fraudulent operations are important. In the present embodiment, since the storage areas to be rewritten are different from each other in the power-on processing and the second storage area check initialization processing, which are such important processing, mixing of unnecessary storage contents is suppressed. , Security can be improved.

  (15) The power-on processing includes initializing the storage contents of the first storage area, and the second storage area check initialization processing includes initializing the storage contents of the second storage area. This makes it possible to associate each process with a storage area for which storage contents are to be initialized, thereby making it easier to manage the storage area of the main control RAM 100c.

  (16) The power-on processing includes checking whether the storage content of the first storage area is normal, and the second storage area check initialization processing includes checking that the storage content of the second storage area is normal. Checking whether or not. This makes it possible to associate each process with a storage area to be checked for storage contents, thereby making it easier to manage the storage area of the main control RAM 100c.

  (17) The second storage area power-on process is a process including determining whether or not the front door 12 is open. I can say. In the present embodiment, the second storage area power-on processing, which is such an important processing, is performed as a subroutine of the power-on processing, and the first storage area is not rewritten in the power-on processing but the first storage area. The storage contents of the second storage area different from the storage area are rewritten. Therefore, the management of the storage area of the main control RAM 100c can be further facilitated, and unnecessary storage contents can be prevented from being mixed, thereby improving 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 has been operated, fraud is easily performed. It can be said that this is an important process regarding the setting device 26. In the present embodiment, the second storage area power-on processing, which is such an important processing, is performed as a subroutine of the power-on processing, and the first storage area is not rewritten in the power-on processing but the first storage area. The storage contents of the second storage area different from the storage area are rewritten. Therefore, the management of the storage area of the main control RAM 100c can be further facilitated, and unnecessary storage contents can be prevented from being mixed, thereby improving security.

The above embodiment may be modified as follows.
How to define the first storage area and the second storage area in the storage area of the main control RAM 100c 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. It is not necessary to set an unused area in each storage area. That is, the storage area that can be rewritten and the storage area that cannot be rewritten only need to be different for each type of processing performed by the main control CPU 100a.

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

  -The storage content stored in the first storage area and the storage content stored in the second storage area may be appropriately changed. For example, information about impropriety may be stored in the first storage area, and information about 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, the information may be classified by type, and the storage area to be stored may be different depending on the type of the information. The types of information include information on reel control, information on effects, and the like, in addition to the information on the progress of the game and the information on injustice described in the above embodiment.

  The main control CPU 100a performs, in addition to the first type processing and the second type processing, a third type processing that does not rewrite both the storage contents of the first storage area and the second storage area of the main control RAM 100c. May go. Further, 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, since it is possible to refer to both the storage content of the first storage area and the storage content of the second storage area in the third type processing, it is possible to easily manage the storage unit and to further reduce the processing of the gaming machine as a whole. Can be more efficient. In the third type of processing, the main control CPU 100a may refer to only one of the storage content of the first storage area and the storage content of the second storage area, or may not refer to either. Is also good. In addition, as the third type processing, for example, at least one of the storage content of the first storage area and the storage content of the second storage area is referred to, and a different subroutine is called and executed based on a result of the reference. Processing can be assumed. As the third type processing, for example, a predetermined subroutine is called in a predetermined order in the third type processing without referring to any of the storage contents of the first storage area and the storage contents of the second storage area. Can be assumed.

  In the above embodiment, the main control CPU 100a differs from the storage area to be rewritten in the processing in part of the processing for 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, it is not limited to this. For example, in all the processes of rewriting either the storage content of the first storage region or the storage content of the second storage region, the storage content of a storage region different from the storage region to be rewritten in the process can be referred to. Is also good. According to this, it is not necessary to perform the same processing as the processing of rewriting the storage content of the predetermined storage area in the processing of rewriting a storage area different from the predetermined storage area, and the processing of the slot machine 10 can be made more efficient overall it can.

  Also, in all of the processing of rewriting either the storage content of the first storage area or the storage content of the second storage area, the storage content of a storage area different from the storage area to be rewritten in the processing cannot be referenced. May be. In addition, in the process of rewriting the storage content of the first storage area, the storage content of the second storage area can be referred to, but in the process of rewriting the storage content of the second storage area, the storage content of the first storage area cannot be referred to. It may be. 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, but in the processing 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, in the second storage area check initialization processing (second type processing), the storage contents of the first storage area may be referred to. Further, in the second storage area power-on processing (second type processing), the storage contents of the first storage area may be referred to. Further, in the game progress process (first type process) relating to the progress of the game, the storage content 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 content of the first storage area and the storage content of the second storage area. That is, the processing performed by the main control CPU 100a includes at least processing for rewriting the storage content of the first storage area while not rewriting the storage content of the second storage area, and processing for rewriting the storage content of the second storage area, A process that does not rewrite the storage content of the storage area may be included, and other processes may be further included.

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

  -The processing procedure in various processes performed by the main control CPU 100a may be changed as appropriate. That is, the processing performed by the main control CPU 100a includes rewriting the storage content of the first storage area of the main control RAM 100c while not rewriting the storage content of the second storage area, and rewriting the storage content of the second storage area. On the other hand, a process of not rewriting the storage content of the first storage area only needs to be included at least.

  For example, if it is determined in step Se01 of the second storage area check initialization processing executed in step Sc10 of the power-on processing that the storage content of the second storage area is not normal, the second storage area After setting the error flag in the second storage area, the second storage area check initialization processing may be ended. In this case, upon returning to the power-on processing after the end of the second storage area check initialization processing, it is determined whether or not an error flag is set, and if the error flag is set, the error stop is performed. If the error flag is not set, the process may proceed to the next process (step Sc11).

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

  In addition, any one of the process of restoring all registers in the second storage area power restoration process executed in step Sf04 of the power restoration process (step Sg06) and the process of restoring the stack pointer of the first storage area (step Sg07). Either or both processes may be executed in the power return process. That is, in the second storage area power return processing, when the determination is affirmative in step Sg05, the second storage area power return processing is terminated, and in the subsequent power supply recovery processing, processing for restoring all registers and the first storage area The processing for restoring the stack pointer may be executed.

The main control CPU 100a may be configured to be able to call and execute another type 2 process or type 1 process in the type 2 process.
-The number of processes classified into the first type process and the second type process may be changed as appropriate. 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 into the first type process may be plural, and the number of processes classified into 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 one. Further, the number of processes classified into the first type process and the number of processes classified into the second type process may be both plural. In this case, the number of processes classified into the first type process and the The number of processes classified into two types of processes may be different.

  -As the first type processing and the second type processing, an interruption processing may be adopted. Further, an interrupt process may be adopted as the first type process, and a process called by the interrupt process (subroutine of the interrupt process) may be adopted as the second type process.

  The main control ROM 100b stores and holds a specific storage area for the processing of rewriting the first storage area of the main control RAM 100c among various processings performed by the main control CPU 100a, while the second storage area May be configured to be stored and held 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 can be rewritten by a process stored and held in a specific storage area of the main control ROM 100b, and the second storage area It can be understood as a storage area that can be rewritten by a process stored and held in a non-specific storage area of the main control ROM 100b.

  In the processing stored in the specific storage area of the main control ROM 100b, another processing stored in the specific storage area or a processing stored in a non-specific storage area is called and executed. May be made. Further, in the processing stored in the non-specific storage area of the main control ROM 100b, the processing stored in the specific storage area may not be called and executed. In the processing stored in the non-specific storage area of the main control ROM 100b, another processing stored in the non-specific storage area may be called and executed, or may not be performed. It may be.

  The main control ROM 100b and the main control RAM 100c may be different memories or different storage areas in the same memory. Similarly, the sub-control ROM 200b and the sub-control RAM 200c may be different memories or 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, but cannot supply power to the sub control RAM 200c of the sub board 200. Good. That is, the sub-control RAM 200c may be configured to be unable to retain the stored contents when the power is turned off.

  The function of the sub-board 200 may be divided into a plurality of boards. For example, a display board for exclusively controlling the effect display device 15, a sound board for exclusively controlling the speaker 14, and a lamp board for exclusively controlling 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 erasing (clearing) the storage content 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 processing of steps Sc09 and Sc10 when the RAM clear switch is operated in the power-on processing shown in FIG.

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

Hereinafter, technical ideas that can be grasped from the above embodiment and other examples will be added.
