Description

  The present invention relates to a gaming machine such as a slot machine provided with main control means for controlling a game.

  2. Description of the Related Art Conventionally, a slot machine, which is a type of gaming machine, includes a microprocessor-structured control unit in which a CPU, a plurality of registers, a stack pointer, a RAM, and a ROM are integrated into a single chip. A game is controlled by executing a predetermined process by executing a stored program. The multiple registers include registers such as accumulator registers, flag registers, general-purpose registers, index registers, interrupt registers, refresh registers, and program counters. The CPU executes various instructions such as arithmetic instructions and transfer instructions included in the program. By updating the value of registers such as accumulator registers, general-purpose registers, and index registers, or updating values (data) stored in the RAM storage area specified by the values (addresses) of general-purpose registers and index registers. Or

  Further, a stack area accessible by a stack area reference address stored in the stack pointer is set in advance in a predetermined storage area of the RAM. Then, by referring to the stack area reference address stored in the stack pointer, the CPU stores the value of each register in the stack area by the push instruction included in the transfer instruction, or the pop instruction included in the transfer instruction. To set the value of each register to the value stored in the stack area.

  In addition, depending on the type of instruction executed by the CPU when updating the value of a predetermined register such as an accumulator register, general-purpose register, or index register, the state of the flag register is the result of updating the value of the predetermined register by the CPU. It is comprised so that it may change based on. Therefore, by using the change in the state of the flag register when the CPU updates the value of the predetermined register, it is possible to cause the CPU to perform processing according to the result of updating the value of the predetermined register.

  Specifically, a zero flag whose state changes according to the operation result of the operation instruction is set in the flag register. For example, the CPU executes a program configured to execute instructions of 3 steps in the following order. By executing, processing according to a change in the state of the zero flag (flag register) is performed. That is, for example, when a counter is configured in a predetermined storage area of the RAM, a load instruction for transferring the count value α of the counter stored in the RAM to the accumulator register is executed (first step), and the count is performed. In order to change the state of the zero flag when the value α is 0, an AND operation is performed on the values of the accumulator registers and the operation result is stored in the accumulator register (predetermined register) (second register) Step), an instruction corresponding to the state of the zero flag is executed (third step). At this time, in the second step, since the state of the zero flag is changed between when the logical product is 1 (α ≠ 0) and 0 (α = 0), the third step In the step, by executing an instruction according to the state of the zero flag, processing according to whether or not the count value α is 0 is performed.

  By the way, the types of instructions executed by the CPU in order to reduce the amount of code compared to the above-described conventional program that causes the CPU to execute processing according to the result of updating the value of a predetermined register, and to further reduce the processing load on the CPU. There is provided a gaming machine including a control unit in which a first zero flag (first bit) and a second zero flag (second bit), each of which operates differently depending on the setting, are set in a flag register (for example, Patent Document 1). Specifically, the first zero flag is configured such that the state changes according to the operation result of the operation instruction, but the state does not change with a specific instruction such as a load instruction included in the transfer instruction. The zero flag is configured such that the state changes according to the operation result of the operation instruction, and the state may change even with a specific instruction. The first zero flag is configured to have substantially the same function as the conventional zero flag described above.

  Therefore, for example, when the CPU executes a program configured to execute instructions of two steps in the following order, the same processing as the conventional processing using the above-described zero flag can be performed. That is, a load instruction for transferring the count value α stored in the RAM to the accumulator register is executed (first step), and an instruction corresponding to the state of the second zero flag is executed (second step). At this time, in the first step, the state of the second zero flag changes depending on whether the count value α stored in the accumulator register is not 0 (α ≠ 0) or 0 (α = 0). Therefore, in the second step, processing according to whether or not the count value α is 0 is executed by executing an instruction corresponding to the state of the second zero flag.

JP 2014-195688 (paragraphs 2174 to 2181, FIGS. 234 to 236, claim 1, abstract, etc.)

  By the way, although the processing executed by the CPU executing the program includes a plurality of functions, it is easy when a problem occurs in one of the plurality of functions or when a function is added. It is desirable to configure the program independently for each process including each function so that the CPU can control the gaming machine by executing a combination of these multiple programs so that the program can be updated. Has been. In this way, only the program corresponding to the function in which the problem occurred can be updated, and only the program for implementing the process for realizing the added function is configured and added independently. You can do it. In addition, by doing so, a plurality of programs for realizing each process can be independently developed in parallel.

  At this time, when the processing by the one program is interrupted, the processing by the other program is temporarily interrupted, and the processing is resumed from the continuation of the one program again. In processing by another program, first, the stack area reference address and the value of each register stored in the stack pointer during processing by one program are transferred to the RAM by a transfer instruction such as a load instruction or a push instruction. It is necessary to save by memorizing. Then, in the processing by another program, finally, the stack area reference address stored in the stack pointer and the value of each register are saved. It must be restored to the value of each register.

  However, in the gaming machine described in Patent Document 1, when each program is configured independently as described above, the state of the second zero flag of the flag register may be changed by a specific instruction such as a load instruction. Since it is configured, the following problems may occur. That is, if the state of the second zero flag changes due to a transfer instruction such as a load instruction executed when saving the stack area reference address and each register value stored in the stack pointer, A value different from the value of the flag register (second zero flag) in the processing by the program is stored in the RAM. Therefore, when returning to processing by one program, the value of the flag register is set to a value different from the value of the flag register before the interruption, which may adversely affect processing by the one program. It was difficult to configure multiple programs independently.

  The present invention has been made in view of the above problems, and an object of the present invention is to provide a technique capable of independently configuring a plurality of programs while reducing the processing load by reducing the code amount of each program. To do.

In order to achieve the above object, the gaming machine of the present invention includes a main control means for controlling a game, wherein the main control means includes a plurality of registers including a flag register, a stack pointer, a first pointer A CPU that executes a plurality of types of programs including a program and a second program, a first program storage area that stores the first program, and an area that is different from the first program storage area and stores the second program A program storage means having a second program storage area, a first stack area corresponding to the first program accessible by a first stack area reference address stored in the stack pointer, and the first stack area Different from the second stack area stored in the stack pointer. A stack means having a second stack area corresponding to the second program accessible by an address for use; a first data storage area corresponding to the first program capable of updating data; and the first data storage area; And a data storage means having a second data storage area corresponding to the second program capable of updating data, wherein the flag register is responsive to an operation result of an operation instruction included in the program. The state may change depending on the first bit that does not change the state in the specific instruction included in the program and the operation result of the operation instruction. and a second bit that may state changes in instruction processing by the first program of the first stack region and the The data in one data storage area can be updated and referenced, and the data in the second stack area and the second data storage area cannot be updated, but can be referred to, and the processing by the second program is the second stack. The data in the area and the second data storage area can be updated and referred to, and the data in the first stack area and the first data storage area cannot be updated, but can be referred to. The CPU includes a first function program capable of performing a first process, and the second program includes a second function program capable of performing a second process by the CPU, and the CPU starts executing the second program. Is performed by interrupting the execution of the first process by the CPU, and the CPU executes the second program. As a process that can be executed, the load instruction included in the specific instruction stores the first stack area reference address stored in the stack pointer in the second data storage area, and stores the stack pointer in the stack pointer. and storing the second stack region reference address, the push instruction included in the program, and saving processing of storing the previous SL plurality of registers each value in the second stack region, the pop instruction contained in the program The values of the plurality of registers are set to the values stored in the second stack area by the save process, and the first stack area is stored in the second data storage area by the save process by the load instruction. And a return process for storing a reference address in the stack pointer, As the processing that can be executed by the CPU executing the first program, the push command or the load is executed. A storage process for storing a value of a specific register including the flag register in the plurality of registers in the first stack area or the first data storage area instead of the register, and the pop instruction or the load instruction. A change process for changing a value of the specific register among the plurality of registers whose values are set by the return process to a value stored in the first stack area or the first data storage area by the storage process; And the storage process interrupts the first process and starts execution of the second program by the CPU. Conducted in the change process, the CPU has finished the execution of the second program, and characterized in that it is carried out before resuming the first processing.

  With this configuration, the flag register may change its state depending on the operation result of the operation instruction, but the first bit that does not change the state of the specific instruction and the operation result of the operation instruction And the second bit whose state may change even with a specific instruction, the amount of code of each program can be reduced and the processing burden on the CPU can be reduced. In addition, the state of the second bit of the flag register may be changed by a specific instruction executed in the saving process by the second program. However, before executing the saving process, the flag register is set in the storing process by the first program. The value of the specific register is stored, and before the process by the second program is terminated and the first process is restarted, the value of the specific register is changed to the value stored by the storage process in the change process by the first program. Therefore, even if the state of the flag register changes during the saving process by the second program, there is no possibility of affecting the processing by the first program after returning from the processing by the second program. can do. At this time, since only a specific register of the plurality of registers needs to be stored in the storage process, it is necessary to excessively increase the storage capacity of the first stack area or the first data storage area used in the process by the first program. Therefore, an efficient program can be configured.

  The first process may be a game control process for controlling the progress of the game, and the second process may be a fraud determination process for detecting fraud.

  If comprised in this way, the 2nd function program for implementing a fraud determination process (2nd process) will be added to a 2nd program independently of the game control process (1st process) which controls progress of a game. Since fraud determination processing for detecting fraud can be added simply, a fraud countermeasure program (second function program) corresponding to a new fraudulent act can be easily created.

  The plurality of registers further include an accumulator register used in the operation instruction and a general-purpose register, the specific register further includes the accumulator register, and the storage processing is performed on the specific register. The value of the specific register is stored in the first stack area or the first data storage area by one push instruction or the load instruction using a special code to be specified, and the change process is performed by changing the special code. The value of the specific register may be changed to the value stored in the first stack area or the first data storage area by the storage process by one pop instruction or the load instruction used.

  With this configuration, the CPU can operate the values of the specific registers all at once by using a special code prepared in advance for the CPU to execute the instruction without creating a new instruction. Processing can be performed by existing instructions.

  Further, the save processing stores the values of the plurality of registers in the second stack area by one push instruction using a special code that designates the plurality of registers as targets, and the return processing includes The value of each of the plurality of registers may be set to the value stored in the second stack area by the save process by one pop instruction using the special code.

  With this configuration, the CPU can operate on the values of each register at once by using a special code prepared in advance for executing instructions, without creating a new instruction. Processing can be performed by existing instructions.

Further, other flags whose states change according to the execution results of various instructions by the main CPU 61 may be configured in the remaining bits (bit0 to bit4 and bit7) configuring the F register.

  General-purpose registers are used in the same way as general program variables. Specifically, data (values) are temporarily stored, counters are configured, and memory addresses are specified. Used to do. Further, the B register and C register, the D register and E register, the H register and L register may be combined and used as a 16-bit register.

  The Q register is used for designating an upper address of a 16-bit memory address. In this embodiment, addresses F000H to F01FH in the built-in RAM area (RAM 65) are set by setting F0H as an initial value. Is used when accessing the first data storage area 65b1 allocated to the memory space and the second data storage area 65b2 allocated to the memory space of the addresses F030H to F0FFH (see FIG. 6). Specifically, for example, when data stored in the area specified by the address F000H of the first data storage area 65b1 is transferred to the A register, a special load instruction (LDQ) reserved in advance is used. The data transfer operation can be performed by designating only the lower address 00H (LDQ A, (00H)).

  In this case, the main CPU 61 specifies the upper address among the 16-bit addresses specifying the memory space of the first data storage area 65b1 by the value (F0H) set in the Q register, and specifies the lower address with the LDQ instruction. By specifying the value (00H), the address of the data transfer target area is specified to be F000H. Then, the main CPU 61 reads out the data stored in the first data storage area 65b1 designated by the address F000H and stores it in the A register. When a load instruction (LD) is used, it is necessary to specify a 16-bit address (LD A, (F000H)). Therefore, a data size of 2 bytes is required for an operand for address specification. By using a special load instruction (LDQ) using the Q register, the data size of the operand for addressing can be reduced to 1 byte. As described above, in the memory map, the memory space whose upper address is F0H set as an initial value in the Q register is used as the data storage unit 65b (first data storage area 65b1, second data storage area 65b2). The Q register can be used efficiently in the processing (program) using the data storage means 65b by not using the stack means 65a (the first stack area 65a1 and the second stack area 65a2).

Further, the fraud determination unit 112 is embodied by the main CPU 61 executing the second program 300 stored in the fraud determination program control area 67a2.

(1) Game control means 100
The game control means 100 of FIG. 9 performs control related to the game of the slot machine 1 and executes a special game (BB game, RB game) that is a game having a higher winning probability of a small role than the normal game and the normal game. There are two types of normal games: general games, RT games that have a higher probability of winning a re-gamer than general games, and AT games that suggest operating procedures for the stop switches 21L, 21M, and 21R that are advantageous to the player. It is included. As shown in FIG. 9, the game control means 100 includes an operation mode determination means 100a and a game state setting means 100b.

(1-1) Operation mode determination means 100a
The operation mode determination means 100a in FIG. 9 determines the presence / absence of a player's operation on the slot machine 1 and a mode such as a long press, and specifically, the bet switches 15 and 17, the start switch 19, and the stop switches 21L. , 21M, 21R, etc., various modes of operation of the slot machine 1 by the player, such as modes of operation by the player, and modes of the player's insertion of medals into the medal slot 25.

(1-2) Game state setting means 100b
The game state setting means 100b shown in FIG. 9 is a symbol determination means 108, which will be described later, as a result of a role lottery process by a role lottery means 103, which will be described later, and a display mode of symbols on the reels 13L, 13M, 13R displayed on the display window 11. The gaming state of the slot machine 1 is set to any one of a plurality of preset gaming states having different advantages for the player, based on the result of the symbol determination processing by.

  Specifically, in a game state in which a normal game is executed, a prize is awarded for a predetermined special role (BB, RB: see FIG. 11) (when “7-7-7” is aligned on the prize line, the BB prize, the prize line When “BAR-BAR-BAR” is aligned above, an RB winning) is set, and the gaming state setting means 100b sets the gaming state of the slot machine 1 to a gaming state in which a special game (BB game, RB game) is executed. The Then, in the BB game, medals exceeding a predetermined number (for example, 300) are paid out, in the RB game, there are a predetermined number (for example, 8 times) small role winnings, or for a predetermined number of times (for example, 12 times). If the special game end condition is satisfied by executing (game) or the like, the special game is ended and the gaming state of the slot machine 1 is changed to a gaming state in which a normal game is executed by the gaming state setting means 100b. Is set.

  The special game (BB game, RB game) is a game state in which the winning probability of the small role is higher than that of the normal game (general game or the like).

  Here, an outline of the game in the slot machine 1 will be described.

  The slot machine 1 is configured such that a game is executed when three medals are inserted. When the insertion sensor 53, the bet switch 15 or the maximum bet switch 17 detects insertion of three medals into the slot machine 1, A horizontal winning line (center line) at the center (middle stage) of the display window 11 becomes effective. Then, when the operation of the start switch 19 is detected on condition that three medals, which are the prescribed number, are inserted, any one of the preset winning lottery results will be described later by the lottery processing using random numbers. 103 (see FIG. 9). In addition, all rotations of the left, middle, and right reels 13L, 13M, and 13R are started, and the symbols of the reels 13L, 13M, and 13R displayed on the display window 11 are adjusted to the rotation angles of the reels 13L, 13M, and 13R. Start to determine.

  Thereafter, the left / middle / right reels 13L, 13M, and 13R are accelerated, and the operation of all the stop switches 21L, 21M, and 21R can be effectively received. After the operation of all the stop switches 21L, 21M, and 21R becomes valid, for example, when it is detected that the left stop switch 21L is operated, the left reel 13L is stopped and the operation of the middle stop switch 21M is detected. Then, the middle reel 13M is stopped, and when it is detected that the right stop switch 21R is operated, the right reel 13R is stopped. Thus, the operation of the stop switches 21L, 21M, and 21R stops the rotation of the left, middle, and right reels 13L, 13M, and 13R corresponding to the stop switches 21L, 21M, and 21R.

  When all three left / middle / right stop switches 21L, 21M, and 21R have been operated, the rotation of all three left / middle / right reels 13L, 13M, and 13R is stopped. At this time, when the symbol of the predetermined winning combination determined by the combination lottery means 103 stops at a predetermined position on the winning line in the middle stage of the display window 11 that has become valid, a winning is awarded, and the number of medals according to the winning mode Is credited or paid out from the medal payout opening 39, and one game is completed. In addition, instead of paying out medals or along with paying out medals, a predetermined profit may be given to the player.

  In the present embodiment, as shown in FIG. 10, as a combination, a special combination (bonus: BB, RB), a small combination (middle bell, one-piece combination 1 to 12, middle cherries, watermelon), re-playing combination (Replay 1) To 26) are preset. Also, as shown in FIG. 11, in the present embodiment, as the result of lottery, the different roles (“middle stage bell”, “one-piece combination 1” to “one-piece combination 12”, “replay 1”, depending on the operation mode. -"Replay 26"), there is a possibility of winning a duplicate win (winning role group: left bell, middle bell, right bell). Then, the role lottery results of the role lottery means 103 include special role winning (bonus winning), small role winning, re-game winning (replay winning), and loss.

  In addition, the prizes include special prizes (bonus prizes) related to transition to special games (bonus games), small prizes related to medal payouts, and re-game prizes related to execution of replays (replays) ( Replay winning).

  Then, for example, when three symbols of each reel 13L, 13M, 13R are arranged on the winning line in each display mode relating to the roles “BB” and “RB” in FIG. Game) is executed.

  In this embodiment, there is no medal payout due to the special role winning (the specified payout number for the special role is 0), and the game is shifted to the bonus game after the game in which the winning mode related to the special role is established. Alternatively, a predetermined payout number (for example, 10) may be set for the special combination, and the bonus game may be started after paying out medals.

  Further, for example, the symbols of the reels 13L, 13M, and 13R are displayed in the display windows in the display modes related to the roles “middle bell”, “single ball 1” to “single ball 12”, “middle cherry”, and “watermelon” in FIG. When three pieces are arranged on the middle 11 winning line, it becomes a small role winning, and the number of medals shown in the “paid out number” column is paid out.

  Further, in FIG. 10, “any” used as the display mode relating to the winning of the middle “cherry” cherry may be arranged on the winning line on any of the symbols provided on the middle reel 13M and the right reel 13R. It means that.

  In addition, when three symbols on each of the reels 13L, 13M, and 13R are arranged on the winning line in the display modes related to the roles “Replay 1” to “Replay 26” in FIG. The game can be played again under the same conditions as the previous game without throwing it in.

  In the present embodiment, the operating modes (push order) of the stop switches 21L, 21M, and 21R that are advantageous to the player are set in advance for each of the winning combination groups “left bell”, “middle bell”, and “right bell”. As shown in the “Remarks” column of FIG. 11, even if the combination lottery result (winning combination group) by the combination lottery means 103 is the same, the player selects which stop switch 21L, 21M, 21R. The stop control means 107 (see FIG. 9) is configured to stop and control each of the reels 13L, 13M, and 13R so that the winning mode (display mode) varies depending on the order of operation.

  That is, by winning one of the winning combination groups “left bell”, “middle bell”, and “right bell” shown in FIG. 11, the winning combination corresponding to the operation sequence of the stop switches 21L, 21M, and 21R. Among them, the stop control means 107 is configured so that the combination for preferentially aligning the symbols related to winning on the winning line is different.

  Specifically, as shown in FIG. 11, for example, when the winning lottery result by the winning lottery means 103 is winning the winning combination group “left bell”, the left stop switch 21L is first displayed by the operation mode determining means 100a. If it is determined that the operation is performed, the symbol “Bell”, which is the display mode corresponding to the winning combination “middle bell” that is most advantageous to the player, is displayed in a state where the symbols are aligned on the winning line. The reels 13L, 13M, and 13R are controlled to be stopped by the stop control means 107.

  On the other hand, when the operation mode determination means 100a determines that the left stop switch 21L has not been operated for the first time, the symbol “Bell” corresponding to the winning combination “middle bell” is aligned on the winning line. In this state, the symbol is not displayed, and the symbol is displayed in a display mode corresponding to any one of “one piece combination 1” to “one piece combination 4”. That is, it is determined by the operation mode determination means 100a that the stop switches 21L, 21M, and 21R are operated in a predetermined operation order corresponding to the winning combination group (“left bell”, “middle bell”, “right bell”). Unless it is done, the symbol is not displayed in the display mode corresponding to the winning combination that is most advantageous to the players included in the winning combination group.

  By the way, special games (BB game, RB game) have a higher winning probability of a small role than normal games, and are easy to receive payout of game medals and are more advantageous to players than normal games It is a game that allows players to win more medals. When a special game “RB” in FIG. 10 is won to shift to a special game, a regular bonus game (RB game) is executed.

  In the regular bonus game, the role lottery table 210 (see FIG. 8) that regulates the winning probability of the lottery process by the role lottery means 103 is based on the normal game lottery table selected in the normal game, compared with the case where the win probability is the normal game. In addition, by switching to the special game lottery table defined with a high probability, the winning probability of the small role is set to be higher than in the normal game. As a result, the special game is a game that is more advantageous to the player than the normal game. Then, after the transition to the regular bonus game, the game is performed a preset number of times, for example, 12 times, or when the small role is won 8 times, the regular bonus game is ended and the game is shifted to the normal game.

  Further, when the special game “BB” in FIG. 10 is won to shift to the special game, a big bonus game (BB game) is executed. In the big bonus game, the regular bonus game described above is continuously executed. After the transition to the big bonus game, the big bonus game is ended when a predetermined number of medals (for example, 300) are paid out. In other words, the big bonus game is set to end the special game (big bonus game) and shift to the normal game when the number of medals paid out in the big bonus game reaches a predetermined upper limit number.

  When the result lottery result of the role lottery means 103 is a special role winning (BB, RB), the symbol stop control based on the special role winning is performed. At this time, the symbol arrangement of the special role winning mode is allocated. If not, the reach to be described later is displayed, and this special role winning is carried over until the symbol arrangement of the special mode winning mode is allocated.

  On the other hand, the small role winning is not carried over to the next game unless the symbol arrangement of the winning combination of the small role is assigned in the game in which the winning combination lottery result is the small role winning. Further, in the case of replay winning, regardless of the timing at which each of the stop switches 21L, 21M, 21R is operated, the symbol (“R1” “R2”) related to any one of “Replay 1” to “Replay 26”. Since the symbols are arranged on the left, middle and right reels 13L, 13M, and 13R so that "7", "Watermelon", "Cherry", and "Bell") are always aligned on the winning line, the player will always win the re-playing role.

  In addition, when any of the winning group “left bell”, “middle bell”, and “right bell” is won, the stop switches 21L, 21M, and 21R are operated at any timing as in the case of the replay symbol. However, the left, middle and right reels 13L and 13M so that the symbols (“Bell”, “R1” and “R2”) related to the winning group “left bell”, “middle bell” and “right bell” are always aligned on the winning line. , 13R, the winner is always awarded one of the "middle bell", "single piece combination 1" to "single piece combination 12". That is, if one of the winning combination groups “left bell”, “middle bell”, and “right bell” is won, and each stop switch 21L, 21M, 21R is operated, which stop switch 21L, 21M, 21R is selected Even if operated at such timing, the reels 13L, 13M, and 13R are controlled to be stopped by the stop control means 107 so that the symbols (see FIG. 10) related to the winnings associated with each operation mode are aligned on the winning line. The

  In addition, when an AT transition condition is satisfied in a general game, the game is shifted to an AT game (AT (assist time) period). In AT game (AT), when winning “Left Bell”, “Middle Bell”, “Right Bell”, or “Replay”, an operation that is advantageous to the player according to the type of winning group (special set winning) The mode (which stop switch should be operated first) is notified to the player. Specifically, when one of “left bell”, “middle bell”, and “right bell” is won, the number of medals to be paid out is 10 as shown in FIG. The operation mode of the stop switch is notified so that the “middle bell” wins. Then, after shifting to the AT period, the AT period ends when a predetermined number of digest games, for example, 50 AT games are performed and the AT end condition is satisfied.

(2) Setting control means 101
The setting control means 101 in FIG. 9 sets setting values (setting 1 to setting 6). This set value is used to select a combination lottery table 210 selected by the table selection means 102 described later. Each setting value is set in each of the plurality of combination lottery tables 210 stored in the game program data area 67b1 of the ROM 67. One of the values is associated. Then, the setting control means 101 determines the ON / OFF state of the change process start switch 56 (FIG. 3) when the power is turned on. When the power is turned on with the change process start switch 56 being ON, a predetermined setting change is made. Start processing.

  Here, the winning probabilities in the normal game lottery are set in a plurality of stages that are distinguished by a plurality of types of setting values (here, six types), and each of the plurality of stage setting values has a combination lottery table shown in FIG. 210 (normal game lottery table) is associated. When the setting change process is started, the manager of the pachinko hall where the slot machine 1 is installed can change the setting value.

  The procedure for changing the setting value is performed as follows, for example. That is, the administrator opens the front door 5, inserts a setting change key (not shown) into the key cylinder of the operation box 49 and rotates with the power switch 50 turned off, and turns on the change processing start switch 56. To. In this state, the setting change process is started by turning on the power switch 50.

  Then, the winning probability setting value is cyclically switched from setting 1 to setting 6 for each operation of the setting change button 52 by the administrator. This set value is notified by displaying 1 to 6 by a 7 segment type set value display LED, for example. When the set value of the winning probability becomes a desired value by operating the setting change button 52 (the display value of the setting value display LED becomes a desired value), the set value is determined by operating the start switch 19. . Then, when the setting change key inserted in the key cylinder is rotated and the change process start switch 56 is turned OFF, the setting change process ends. Thereafter, when a medal is inserted from the medal slot 25, the game is started.

(3) Table selection means 102
The table selection unit 102 in FIG. 9 is a type of game (normal game, RT game, special game, etc.) controlled by the game control unit 100 on the main control board 63, and a set value (setting 1) set by the setting control unit 101. Based on the setting 6), one lottery table is selected from the plurality of part lottery tables 210 shown in FIG. That is, for example, in a normal game, the table selection unit 102 selects a combination lottery table 210 (normal game lottery table) as a lottery table according to a set value (setting 1 to setting 6) of a winning probability.

(4) Role lottery means 103
The combination lottery means 103 in FIG. 9 is a timing at which the start switch 19 is operated, as shown in FIG. 11, out of a plurality of combination lottery results (special combination winning, small combination winning, re-game winning combination, loss) Any one is selected and determined by a lottery process using a random number and a lottery table as a role lottery result in the current game. I have. Here, the random number generating means generates a random number for lottery within a predetermined range (for example, 0 to 16383 in decimal number), and counts the oscillation circuit and the clock signal generated by the oscillation circuit. Counter circuit. Further, the random number extraction means extracts the random number generated by the random number generation means at the timing when the start switch 19 is operated. Since the random number generating means is constituted by a counter circuit or the like, the numerical value generated by the random number generating means is not strictly a random number. However, since the timing at which the start switch 19 is operated is considered to be random, the numerical value extracted by the random number extraction means can be practically handled as a random number. A random number may be generated by a random number generator.

  Furthermore, the role lottery table 210 in FIG. 10 is predetermined for each random number within the range generated by the random number generating means, and whether or not it corresponds to one of the preset role lottery results, The random number extracted by the random number extraction means is compared with the lottery table to determine which of the plurality of lottery results the extracted random number corresponds to.

(5) Notification determining means 104
The notification determination means 104 of FIG. 9 determines whether to notify the operation mode of the stop switches 21L, 21M, and 21R advantageous to the player. For example, even if the role lottery result is “right bell”, if the player cannot know that fact, the player does not always operate the right stop switch 21R first, and the “middle bell” is displayed. It is not always possible to align. On the other hand, in an AT game, when the result lottery result becomes “right bell”, the fact is notified, and the player is prompted to operate the right stop switch 21R first, thereby increasing the chance that the player receives a payout. It becomes possible.

  Here, when the AT transition condition is satisfied, it is determined that the notification is determined by the notification determination means 104, the state of the AT period flag stored in the gaming state flag 220 (see FIG. 7) is set to ON, The gaming state is set to a gaming state in which the AT game is executed by the gaming state setting means 100b. Further, the state of the AT period flag stored in the gaming state flag 220 is set to OFF when a predetermined number of digest games (for example, 50 times) are executed, and the gaming state is set to the gaming state. The game state in which the general game is executed independently is set by the means 100b. For example, by assigning any one bit of the 1-byte memory area forming the gaming state flag 220 to the flag during the AT period and setting the bit to ON or OFF, the flag state during the AT period is set. The game state flag 220 can be stored.

  Specifically, as shown in FIG. 11, after winning the next game won for “middle cherries” or the transition lottery executed with a winning probability of 1/2 at the time of “watermelon” winning, After the predetermined number of games that have been set are consumed, the AT transition condition is established. In addition, when winning the transition lottery at the time of “watermelon” winning, for example, the number of games of 4 games to 32 games is set as a precursor period by lottery.

  In the AT game, as described above, when one of the winning group “left bell”, “middle bell”, and “right bell” is won, an operation mode advantageous to a player preset in each winning group (Operation order) is notified to the player. Then, after the transition to the AT period, the AT period ends when an AT game of a preset number of digested games is performed.

  Further, as shown in FIG. 11, in the AT game, when the winning combination group “watermelon” is won, the winning lottery for determining whether or not to add to the number of digested games as the AT end condition is 1/2 the winning probability In the case of winning, an additional condition is established, and a predetermined additional number (for example, 10 games) is added to the number of digested games.

(6) Command creation means 105
The command creation means 105 of FIG. 9 is data relating to the result lottery result in the role lottery process by the role lottery means 103, and data relating to the operation of the operation tool operated by the player such as the stop switches 21L, 21M, 21R, and the start switch 19. A command for transmitting various data such as data relating to a determination result by the symbol determination means 108 described later to the sub control board 73 (sub CPU 71) is generated. The command generated by the command creating unit 105 is transmitted to the sub control board 73 by the sub control command transmitting unit 110 described later.

  The command creation unit 105 creates a command according to the determination result of the notification determination unit 104. That is, the notification determining unit 104 uses the command created by the command creating unit 105 as a command that can identify the type of specific set winning (a command that can be used to identify an advantageous operation mode), or a command that cannot identify the type of specific set winning ( It also has a function of determining whether the command is an advantageous operation mode.

  Specifically, as shown in FIG. 11, the command creation unit 105 includes commands “0” to “8” as commands that can identify the lottery result when the lottery unit 103 executes the lottery. Create As will be described later, the sub control board 73 selects an effect to be executed based on the sent command. In other words, the command creation means 105 creates a command that indicates the contents of the effect executed on the sub control board 73.

  When the notification determination unit 104 determines that the operation mode advantageous to the player is not notified, that is, when the flag during the AT period is set to OFF, the command creation unit 105 A command is created that does not include data indicating the type of the winning combination group (“left bell”, “middle bell”, “right bell”) that can be identified as having won the crab but cannot identify the corresponding winning group. Further, when it is determined by the notification determining means 104 that an operation mode advantageous to the player is notified, that is, when the AT period flag is set to ON, the winning combination group (“left bell” “middle bell” is selected. “Right bell”) is included, and a command that can identify the corresponding winning group is created.

  For example, as shown in FIG. 11, when the flag during the AT period is OFF, the command creating means 105 may win any of the winning group “left bell”, “middle bell”, or “right bell”. , The same command “No. 1” is created so that the winning combination group of “Bell group” cannot be identified. On the other hand, the command creating means 105 selects the “second bell” command when the “left bell” is won when the AT period flag is ON, and the “third” command when the “middle bell” is won. If “Right Bell” is won, “No. 4” command is created.

  The command creation means 105 creates the same command for the other lottery results, regardless of whether the AT period flag is ON or OFF. That is, if the “middle cherry” is won, the command “No. 5” is given, the command “No. 6” is won if the “watermelon” is won, and the command “7” if the “BB” is won. If “RB” is won, a command “8” is created. In case of a loss, a command “No. 0” is created.

(7) Reel detecting means 106
The reel detection means 106 in FIG. 9 sends detection signals from the left / middle / right position sensors 55L, 55M, and 55R to the reel motors 14L, 14M, and 14R that drive the left / middle / right reels 13L, 13M, and 13R. Based on the number of supplied pulses, the rotational positions of the left, middle, and right reels 13L, 13M, and 13R are detected. This reel detection means 106 corresponds to a symbol located at a predetermined reference position (for example, the middle stage of the display window 11 in this embodiment) while the left, middle, and right reels 13L, 13M, 13R are rotating and stopped. Each frame number is detected.

(8) Stop control means 107
The stop control means 107 in FIG. 9 performs stop control of each reel 13L, 13M, 13R using the stop table 211 based on the operation of each stop switch 21L, 21M, 21R, and is variable by each reel 13L, 13M, 13R. Each displayed symbol is stopped in a display mode corresponding to the winning lottery result of the winning lottery means 103. This stop control means 107 performs stop control of each reel 13L, 13M, 13R for each game based on the winning lottery result determined by the winning lottery means 103 and the operation mode of each stop switch 21L, 21M, 21R.

  As shown in the “Remarks” column of FIG. 11, when one of the winning group “left bell”, “middle bell”, or “right bell” is won, the first stop switch to be operated is selected. The different combinations are set differently. Further, the operation mode that is advantageous differs depending on the types of the winning combination groups “left bell”, “middle bell”, and “right bell”.

  As the stop table 211 (see FIG. 8) for determining the stop position of each reel 13L, 13M, 13R, a plurality of tables are set corresponding to each of the winning lottery results of the winning lottery means 103. The stop table 211 has a predetermined number of sliding frames for each reel 13L, 13M, 13R according to the rotational position of the reels 13L, 13M, 13R when the stop switches 21L, 21M, 21R are operated. The reels 13L, 13M, and 13R are formed so that the number of sliding frames is different corresponding to the stop operation order of the corresponding stop switches 21L, 21M, and 21R.

  Further, if the winning lottery result of the winning lottery means 103 is a win for any of the winning combinations, the stop control means 107 and the stop table 211 selected based on the winning lottery result and the stop switches 21L, 21M, From the rotational position of each reel 13L, 13M, 13R when 21R is operated, the number of sliding frames of each reel 13L, 13M, 13R is determined so as to win the winning combination, and each reel 13L, 13M, 13R is determined. Perform stop control. On the other hand, if the winning lottery result by the winning lottery means 103 is lost, the stop control means 107 has operated the stop table 211 selected based on the lost winning lottery result and the stop switches 21L, 21M, and 21R. From the rotational position of each reel 13L, 13M, 13R, the number of sliding symbols of each reel 13L, 13M, 13R is determined so as not to win any of a plurality of roles, and each reel 13L, 13M, 13R Perform stop control.

  By the way, there is an upper limit on the number of sliding frames, and if the stop switches 21L, 21M, and 21R are not operated at the timing when the reels 13L, 13M, and 13R are respectively at predetermined rotational positions, the stop control means 107 is Even if the winning lottery result by the winning lottery means 103 is a win for any of the winning combinations, the reels 13L, 13B, and 13D are displayed so that the symbols displayed on the display window 11 are stopped and displayed in a winning manner corresponding to the winning winning combination. 13M and 13R cannot be controlled to stop. In other words, the stop control unit 107 determines that the stop switches 21L, 21M, and 21R are operated at the timing when the reels 13L, 13M, and 13R are at predetermined rotation positions based on the combination lottery result of the combination lottery unit 103. The reels 13L, 13M, and 13R are controlled to stop so that the symbols displayed on the display window 11 are stopped and displayed in a winning manner corresponding to the winning combination.

  In addition, the stop control means 107, when the result lottery result of the role lottery means 103 is a special role winning (BB, RB), each stop switch 21L, 21M, 21R is not operated at an appropriate timing. When the symbol arrangement of the winning mode cannot be assigned, the reels 13L, 13M, and 13R are controlled to stop so that the symbol is displayed on the display window 11 in a special display mode (hereinafter referred to as “reach eyes”).

(9) Symbol determination means 108
The symbol determination means 108 in FIG. 9 has the reels 13L, 13M, 13R stopped by the stop control means 107 being stopped based on the respective rotational positions of the reels 13L, 13M, 13R detected by the reel detection means 106. A symbol determination process is performed to determine whether or not the display mode of each symbol is a predetermined display mode.

  The symbol determination means 108 determines that the special combination is won when the symbols are arranged on the winning line in the display modes shown in “BB” and “RB” of FIG. Further, when the symbols are aligned on the winning line in the display forms shown in “middle stage bell”, “single part combination 1” to “single part combination 12”, “middle stage cherry”, and “watermelon”, it is determined that the small part prize has been won, and “replay 1 When the symbols are aligned on the winning line in the display modes shown in “Replay 26”, it is determined that the re-playing role is won.

(10) Dispensing control means 109
The payout control means 109 of FIG. 9 gives a predetermined profit (privilege) to the player based on the determination result by the symbol determination means 108. The payout control means 109 determines that the number of credit medals stored is the upper limit value (this embodiment) if the symbol determination means 108 determines that one of a plurality of winning combinations has been won, and if there is a medal payout. After reaching 50, for example, the hopper unit 43 is operated to pay out medals by the payout number corresponding to the winning combination. Further, the payout control means 109 increases the credit medals by the payout number instead of the operation of the hopper unit 43 as a medal payout until the number of stored credit medals reaches the upper limit value.

(11) Sub-control command transmission means 110
The sub-control command transmission unit 110 in FIG. 9 transmits commands including various data created by the command creation unit 105 from the main control board 63 to the sub-control board 73 as predetermined information by one-way communication. This sub-control command transmission means 110 is created by the command creation means 105 and set by the setting control means 101, gaming state such as normal game and special game, the role lottery result of the role lottery means 103, symbol determination A command including data representing the state of the slot machine 1 such as a symbol determination result by the means 108, a rotation / stop state of each reel 13L, 13M, 13R, a medal payout state by the payout control means 109, etc. is transmitted to the sub-control board 73. .

  Further, the sub control command transmission means 110 transmits a command created by the command creation means 105 including data indicating the detection state of the inserted medal by the insertion sensor 53, the operation state of the bet switch 15 and the maximum bet switch 17, and the like. 73. Further, the sub control command transmission means 110 receives a command created by the command creation means 105 including data indicating how various switches such as the start switch 19 and the stop switches 21L, 21M, and 21R are operated by the player. Transmit to the sub-control board 73.

(12) Notification means 111
9 is determined by the notification determining unit 104 to execute a predetermined effect for notifying the operation mode of each of the stop switches 21L, 21M, and 21R advantageous to the player, that is, an AT period flag. Is set to ON, if the winning lottery result of the winning lottery means 103 is one of the winning group “left bell”, “middle bell”, and “right bell”, the winning winning combination By displaying the operation sequence of each of the stop switches 21L, 21M, 21R advantageous to the player corresponding to the group on the notification display 60 directly controlled by the main control board 63, the operational mode advantageous to the player is notified. Perform the production. Specifically, when an operation mode advantageous to the player “operates the left stop switch 21L first” is set in the winning combination group, “123” or “ “1--” is displayed. Note that the notification unit 111 may display the information indicating the type of the winning combination group won by the notification display 60.

  Further, when it is determined by the notification determining means 104 that a predetermined effect for notifying an operation mode advantageous to the player is not executed, that is, when the flag during the AT period is set to OFF, the notification means 111 The display for notifying the operation mode advantageous to the player is performed on the notification display 60, and the effect of notifying the operation mode advantageous to the player is not performed.

  Note that the notification means 111 may display an operation procedure advantageous to the player on the credit indicator 45, or notifies the player of an operation procedure advantageous to the player by a reel effect using the reels 13L, 13M, and 13R. Also good.

(13) Fraud determining unit 112
The fraud determination unit 112 in FIG. 9 performs fraud determination processing (step S103 in FIG. 12) for determining whether fraud has been performed on the slot machine 1. In the present embodiment, the fraud determination unit 112 detects fraud by determining whether or not there is an abnormal insertion of medals into the medal insertion slot 25. Specifically, the fraud determination unit 112 monitors the medal detection signal by the insertion sensor 53, and when the output mode of the medal detection signal is abnormal, that is, the medal detection signal at the time of normal medal insertion. When the detection signal of the insertion sensor 25 is output in a different manner, the fraud is detected by determining that there is an abnormal insertion of medals, and it is determined that the slot machine 1 has been fraudulent.

  When the fraud determination unit 112 determines that fraud has been performed on the slot machine 1, the fraud determination unit 112 sets the state of the medal insertion abnormality flag stored in the fraud determination flag 310 (see FIG. 7) to ON. . For example, the state of the medal insertion abnormality flag is set by assigning one of the bits of the 1-byte memory area forming the fraud determination flag 310 to the medal insertion abnormality flag and setting the bit to ON or OFF. Can be stored in the fraud determination flag 310.

(Sub control board)
Next, the configuration of the sub control board 73 will be described in detail with reference to FIG. The sub CPU 71 of the sub control board 73 is for receiving a command transmitted from the main control means 80 (main control board 63) and performing an effect according to the operation and state of the main control means 80. As shown in FIG. 9, the sub-control board 73 is equipped with various functions realized by executing a program stored in the memory 75 and various functions realized by controlling hardware. Has been.

(1) Sub-control command receiving means 400
The sub-control command receiving unit 400 in FIG. 9 receives commands including various data transmitted by the sub-control command transmitting unit 110 of the main control unit 80 as predetermined information. The sub control command receiving means 400 receives the command transmitted from the main control means 80, and when receiving the command, notifies the respective functions mounted on the sub control board 73 according to the type of the command.

(2) Production content determination means 401
The effect content determination means 401 in FIG. 9 is for determining the contents of the effect according to the command received by the sub control command receiving means 400. Specifically, a moving image to be displayed on the liquid crystal display 27 is determined from an effect pattern set in advance corresponding to the progress of the game, the result of the role lottery means 103, or the like from the speakers 31L and 31R. An effect such as determining the music and sound to be played, and flashing the light sources of the upper lamp unit 33 and the lower lamp units 37L and 37R all at once or individually is determined.

  If the received command corresponds to the command during the AT period and the type of the winning combination group (bell group) can be identified, the production content determination unit 401 can identify the player corresponding to the type of the winning group. The contents of the effect are determined so that an effect that does not know the operation mode advantageous to the player is executed unless the received command corresponds to the command during the AT period. For example, if the “No. 1” command shown in FIG. 11 is received according to the result of lottery, it is not during the AT period, so it is understood that one of the winning groups of “Bell Group” has been won. Select one production from a group of productions that do not know whether "Left bell", "Middle bell", or "Right bell" was won. In addition, when the “No. 2” command shown in FIG. 11 is received, one of the effects indicating that “Left Bell” has been won or the effect of prompting the user to operate the left stop switch 21L first is selected. Select. When the “No. 3” and “No. 4” commands shown in FIG. 11 are received, the effect contents are determined in the same manner.

  Furthermore, when the contents-deciding means 401 receives the commands “No. 5” to “No. 8” shown in FIG. 11, similarly, the production contents determination means 401 starts from the production group that suggests the possibility of winning each winning role group. Select the production. Further, when the “0” command is received, similarly, one effect is selected from the effect group corresponding to the loss so as not to impair the player's expectation.

  For example, the operation content of the stop switches 21L, 21M, and 21R is displayed on the liquid crystal display 27, and the operation order of the stop switches 21L, 21M, and 21R is notified by sound through the speakers 31L and 31R. The lamps provided on the stop switches 21L, 21M, and 21R are blinked in a predetermined order to notify the operation order of the stop switches 21L, 21M, and 21R, and the backs provided on the reels 13L, 13M, and 13R. There are effects such as blinking the lights in a predetermined order and notifying the operation order of the stop switches 21L, 21M, and 21R.

  And the effect content determination means 401 transmits the signal containing the data regarding the determined effect content to the display control means 402 and the audio | voice control means 403 which are demonstrated below.

(3) Display control means 402
The display control unit 402 in FIG. 9 displays a moving image on the liquid crystal display 27 based on the data included in the signal transmitted from the effect content determination unit 401, and displays the upper lamp unit 33 and the lower lamp units 37L and 37R. Perform effects such as flashing light sources all at once or individually.

(4) Voice control means 403
The voice control unit 403 in FIG. 9 performs effects such as playing music from the speakers 31L and 31R and outputting sound based on the data included in the signal transmitted from the effect content determination unit 401.

(Operation)
Next, the operation of the slot machine 1 will be described with reference to FIGS.

  The timer interrupt process shown in FIG. 12 is a process executed each time an interrupt process is performed in the main CPU 61 of the main control means 80. In FIG. 12, only the process for detecting a medal inserted into the medal slot 25 is shown in the process executed in the timer interrupt process for ease of explanation. This process is not shown in the figure.

  Each process described on the left side of the page of FIG. 12 is a process executed by the main CPU 61 executing the first program 200 stored in the game program control area 67a1. Each process described on the right side is a process executed by the main CPU 61 executing the second program 300 stored in the fraud determination program control area 67a2. Further, as shown in the figure, the start of the execution of the second program 300 by the main CPU 61 is performed by interrupting the execution of the game control process by the main CPU 61 executing the game program 201.

  First, in the game control process executed by the main CPU 61 executing the game program 201, the game control means 100 confirms the state of the input port to which the sensor output of the input sensor 53 is input, and the sensor to the input port is detected. Depending on the input state of output, the state of the input sensor flag stored in the port flag 221 (see FIG. 7) is set to ON or OFF (step S1), and the game control process is temporarily interrupted. For example, by assigning any one of the bits of the 1-byte memory area forming the port flag 221 to the input sensor flag and setting the bit ON or OFF, the state of the input sensor flag is changed to the port flag. 221 can be stored.

  Subsequently, in the storage process performed by the main CPU 61 executing the storage program 202 before the execution of the second program 300 by the main CPU 61 is started, as shown in FIG. ), The values (A, B) of the A and F registers among the plurality of registers are stored in the first stack area 65a1 accessible by the first stack area reference address SP1 stored in the SP (step S2). ). At this time, the values of the A register and the F register are stored in the first stack area 65a1 by one push instruction (PUSH AF) using the special code AF that designates the A register and the F register as a transfer target. Thus, the A register and the F register correspond to the “specific register” of the present invention.

  Next, before the fraud determination process (step S103) by the fraud determination program 301 is performed, the main CPU 61 executes the save program 302 to execute the save process. In the saving process, first, as shown in FIG. 13B, the first stack area reference address SP1 stored in the SP is stored in the second data storage area 65b2 by the load instruction (LD (W2), SP). Is stored in the area specified by the address W2 (step S100: save process 1). At this time, as shown in the figure, the state of the TZ flag (see FIGS. 4B and 5B) of the F register is changed by the load instruction (specific instruction), so that the value of the F flag becomes low. → It may change to 'b'.

  Next, as shown in FIG. 14A, the second stack area reference address SP2 is stored in the SP by a load instruction (LD SP, SP2) (step S101: save process 2). Note that the second stack area reference address SP2 stored in the SP at this time is a fixed value stored in advance in the fraud determination program data area 67b2 of the ROM 67, for example. Then, as shown in FIG. 14 (b), the values of the A register, the F register, and the general-purpose register (I, B ', C, D, E, F, G, H) are set to SP by a push instruction (PUSH). Is stored in the second stack area 65a2 accessible by the second stack area reference address SP2 stored in (step S102: save process 3). At this time, the value of each of the A register, the F register, and the general-purpose register is set to the second stack area by one push instruction (PUSH ALL) using the special code ALL that designates the A register, the F register, and the general-purpose register as a transfer target. Store in 65a2. Note that the Q register may be designated as a transfer target together with the A register, the F register, and the general-purpose register by the special code ALL.

  Subsequently, in the fraud determination process performed by the main CPU 61 executing the indeterminate determination program 301, the fraud determination unit 112 stores the input sensor flag stored in the port flag 221 of the first data storage area 65 b 1 of the RAM 65. The state is confirmed, and it is determined whether or not there is an abnormality in the insertion of medals into the medal insertion slot 25 (step S103). Specifically, the fraud determination means 112 measures the medal insertion interval and the duration of the detection signal output by the insertion sensor 53 in the state where the medal is detected, thereby determining the medal insertion slot 25. It is determined whether or not the charging is abnormal. Then, the fraud determination unit 112 determines that fraud has been performed on the slot machine 1 when the medal insertion is abnormal, and the medal insertion abnormality flag stored in the fraud determination flag 310 (see FIG. 7). Set the state to ON. At this time, as shown in FIG. 15A, the values of the A register, the F register, and the general-purpose register change in the fraud determination process.

  Next, after the fraud determination process (step S103) by the fraud determination program 301 is performed, the main CPU 61 executes the return program 303 to execute the return process. In the return processing, first, as shown in FIG. 15B, the values (i '', b '', c '', d '') of the A register, the F register, and the general-purpose register by a pop instruction (POP). , E '', F '', G '', H '') stored in the second stack area 65a2 by the save process 3 (step S102) (i, b ', c) , D, E, F, G, G) (step S104: return processing 1). At this time, the values of the A register, the F register, and the general-purpose register are set to the values stored in the second stack area 65a2 by the save process 3 (step S102) by one pop instruction (POP ALL) using the special code ALL. Set. At this time, if the value of the F register has changed in the save process 1 (step S100: see FIG. 13B) (b → ro ′), as shown in FIG. 15b, the game control process A value (b ') different from that before the interruption is stored in the F register.

  Then, as shown in FIG. 16A, the first instruction stored in the area specified by the address W2 of the second data storage area 65b2 by the save process 1 (step S100) by the load instruction (LDSP, (W2)). One stack area reference address SP1 is stored in SP (step S105: return processing 2), and the main CPU 61 ends the execution of the second program 300.

  Subsequently, in the change process executed by the main CPU 61 executing the change program 203 before the game control process is restarted in step S4, as shown in FIG. 16B, a return is made by a pop command (POP). Of the A registers, F registers, and general-purpose registers whose values are set by processing 1 (step S104), the values (A, B ') of the A registers and F registers are stored in the first stack area 65a1 by storage processing (step S2). The value is changed to the value stored in (i, b) (step S3). At this time, the values of the A register and the F register are changed to the values stored in the first stack area 65a1 by the storage process (step S2) by one pop instruction (POP AF) using the special code AF. At this time, in the return process 1 (step S104: see FIG. 15B), even if a different value (B ′) from that before interrupting the game control process is stored in the F register, FIG. ), The value in the F register can be changed to the same value (B) as before the game control process is interrupted.

  Subsequently, when the game control process is resumed (step S4), the game control means 100 checks the state of the medal insertion abnormality flag stored in the fraud determination flag 310 of the second data storage area 65b2 of the RAM 65. If the medal insertion abnormality flag is set to OFF, the game control means 100 checks the state of the insertion sensor flag stored in the port flag 221 of the first data storage area 65b1 of the RAM 65, and the insertion sensor flag. If is set to ON, it is determined that a normally inserted medal has passed the medal selector 48 (selector determination processing), the medal insertion into the slot machine 1 is counted, and the process is terminated.

  On the other hand, if the medal abnormality flag is set to ON, the game control means 100 is configured to determine that an abnormal medal has been inserted (selector determination processing) and to proceed to error processing.

(Comparative example)
Next, a comparative example of timer interrupt processing will be described with reference to FIGS. In the following description, the same operations as those included in the timer interrupt process shown in FIG. 12 are omitted by citing the same step numbers in FIGS. An explanation will be made focusing on operations different from the timer interrupt processing shown in FIG.

(1) Comparative Example 1
A comparative example 1 will be described with reference to FIG. The difference between the comparative example 1 and the timer interrupt process shown in FIG. 12 is that the storage process (step S2) and the change process (step S3) are not executed. In the comparative example 1, when the value of the F register is changed in the save process 1 (step S100: see FIG. 13B) (B → B ′), the return process 1 (Step S104: FIG. 15B). ))), There is a possibility that a different value (B ′) from before the game control process is interrupted is stored in the F register. Therefore, in the first comparative example, the process by the second program 300 executed by interrupting the game control process may affect the game control process by the first program 200 restarted in step S4.

(2) Comparative Example 2
Comparative Example 2 will be described with reference to FIG. The second comparative example differs from the timer interrupt process shown in FIG. 12 in that the second program in which the process corresponding to the storage process (step S2) and the change process (step S3) is stored in the fraud determination program control area 67a2 It is a point implemented by performing 300 (step S200, step S201). In Comparative Example 2, the value of the first stack area 65a1 used in the interrupted game control process is updated in the storage process in Step 200 and the change process in Step 201, which is performed by executing the second program 300. Is done. Therefore, in the comparative example 2, the process by the first program 200 stored in the game program control area 67a1 and the process by the second program 300 stored in the fraud determination program control area 67a2 can be performed independently. Can not. In addition, since the process by the second program 300 executed by interrupting the game control process updates the value of the first stack area 65a1 used by the game control process, the game control by the first program 200 resumed in step S4. Processing may be adversely affected.

(3) Comparative Example 3
Comparative Example 3 will be described with reference to FIG. The comparative example 3 differs from the timer interrupt process shown in FIG. 12 in that the process corresponding to the save process (step S102) and the return process 1 (step S104) is the first program stored in the game control program control area 67a1. 200 is executed instead of the storage process (step S2) and the change process (step S3) (step S300, step S301). In the comparative example 3, unlike the comparative example 1 and the comparative example 2, before restarting the game control process, the value of each register can be restored to the value of each register before the interruption, and the game program control area 67a1 The processing by the first program 200 stored in the program and the processing by the second program 300 stored in the fraud determination program control area 67a2 can be performed independently. However, in Comparative Example 3, since the value of each register is stored in the first stack area 65a1 in step S300, the first stack area used in the processing by the first program 200 stored in the game program control area 67a1. There is a possibility that the storage capacity of 65a1 needs to be excessively increased.

  As described above, in the above-described embodiment, the state of the F register may change according to the operation result of the operation instruction, but the Z flag that does not change the state with the specific instruction and the operation of the operation instruction. Since the state may change depending on the result and the TZ flag may change even with a specific instruction, the code amount of each program can be reduced to reduce the processing load on the main CPU 61. Further, there is a possibility that the state of the TZ flag of the F register is changed by the load instruction executed in the saving process (step S100 in FIG. 12) by the saving program 302. However, before executing the saving process, the storage program 202 stores the TZ flag. In the process (step S2 in FIG. 12), the values of the A register and the F register are stored. Before the process by the second program 300 is finished and the game control process is restarted, the change process by the change program 203 (step S3 in FIG. 12). ), The values of the A register and the F register are changed to the values stored in the storing process. Therefore, even if the state of the F register changes in the save process, there is no possibility of affecting the game control process after the return from the process by the second program 300, so that a plurality of programs can be configured independently. At this time, since only the A and F registers of the plurality of registers need be stored in the storage process, it is necessary to excessively increase the storage capacity of the first stack area 65a1 used in the process by the first program 200. And an efficient program can be configured.

  Further, independently of the game control process for controlling the progress of the game, the fraud determination process for detecting the fraud is added only by adding the fraud determination program 301 for executing the fraud determination process to the second program 300. Therefore, the fraud determination program 301 corresponding to a new fraudulent act can be easily created.

  In addition, by using the special code AF and special code ALL prepared in advance for the main CPU to execute the transfer instruction, the values of multiple registers can be operated at once, so a new instruction is created. It is possible to perform processing according to an existing instruction without doing so.

  Further, as shown in FIG. 6, the memory space used by the processing by the first program 200 and the memory space used by the processing by the second program 300 are arranged independently of each other and between the memory spaces of each other. Since an unused area of, for example, 16 bytes or more is arranged in the memory, both memory spaces can be prevented from physically interfering with each other and, for example, an illegal operation performed for one process (memory space) It is possible to prevent the action from affecting other processes (memory space).

  The present invention is not limited to the above-described embodiment, and various modifications other than those described above can be made without departing from the spirit of the present invention.

  For example, in the storage process in step S2 of FIG. 12, the value of the specific register (A register, F register) may be stored in the first data storage area 65b1 by a load instruction. In this case, in the change process in step S3 of FIG. 12, the value of the specific register (A register, F register) is changed to the value stored in the first data storage area 65b1 in the storage process by the load instruction. Good.

  The register set 64 may further include a so-called back register for the A register, the F register, and the general-purpose register. In this case, after the save process 3 in step 102 in FIG. The value of the back register may be stored in the second stack area 65a2 or the second data storage area 65b2 by a transfer instruction and saved.

  In the above-described embodiment, the process (game control process) by the first program 200 is interrupted, and then the process is secondly shifted to the process by the program 300 (injustice determination process) by a call instruction or the like. The processing by the first program 200 may be forcibly interrupted by interrupt processing or the like, and the processing by the second program 300 may be executed. In the embodiment described above, as the game control process for controlling the progress of the game, the input port input process (step S1 in FIG. 12) to which the sensor output of the input sensor 53 is input and the selector for determining the input sensor output. The medal insertion determination process combined with the determination process (step S4 in FIG. 12) has been described as an example. However, the process for determining power interruption, the process for outputting the phase of the motor, the process for transmitting a command, the credit indicator, etc. The game control process may be configured by further combining the process of changing the lighting state of lamps such as 45 and the notification display 60.

  In the above-described embodiment, the case where the present invention is applied to the slot machine 1 (rotating game machine) capable of AT games has been described. However, the slot machine (rotating game machine) having no AT function is described. The present invention can be similarly applied even to a slot machine having no bonus function.

  In each of the above embodiments, the slot machine 1 has been described as an example of the gaming machine of the present invention. However, the present invention is applied to a gaming machine called a parrot that is a combination of a slot machine and a pachinko machine. In addition, when the present invention is applied to such a gaming machine, a gaming ball (pachinko ball) as a gaming value may be employed. Furthermore, the present invention may be applied to a pachinko machine.

  Further, instead of the reels 13L, 13M, and 13R in the slot machine 1 of the above-described embodiment, an image display device such as a liquid crystal display or a CRT is used, and a plurality of symbols are sequentially displayed on the image display device. May be. The number of rotating reels may be two or more, and may be set to an optimal number as appropriate according to the game mode.

  The present invention can be widely applied to gaming machines such as slot machines.
