Description

  The present invention relates to a gaming machine that displays symbols in a variable manner on a symbol display device and generates a special prize state after the symbols are stopped in a predetermined manner, and in particular, without increasing the difficulty and data capacity of development and design. The present invention relates to a gaming machine, an access control program, and a game control method suitable for preventing unauthorized operation.

  Pachinko machines and other gaming machines are subjected to a certification test at a designated certification organization in accordance with the law. In the certification test, one of the passing conditions is that the instruction code sequence executed by the microprocessor of the gaming machine satisfies a certain requirement. Only gaming machines that pass the certification test can be distributed to the market.

  However, after distribution to the market, gaming machine boards and chips (semiconductor devices such as LSIs) are replaced with unauthorized ones, unauthorized chips are added, microprocessors are modified, microprocessor ROMs are installed, etc. Injustices such as rewriting may be performed. These are mainly performed by a third party for illegal operation of the gaming machine for the purpose of obtaining illegal profits.

  Moreover, the same problem can be considered when the gaming machine is illegally operated due to an electrical / physical error. As an electrical / physical error, for example, when an instruction code string is read (fetched), a bit error occurs due to the influence of electromagnetic waves or static electricity, and the contents of the instruction code string change. It is done.

  As described above, the illegal operation caused by the illegal act or the error has a large damage to the pachinko hall or the like, and it is required to prevent this.

  Conventionally, as a technique for preventing unauthorized operation of a microprocessor or the like, for example, techniques described in Patent Documents 1 and 2 are known.

  The technique described in Patent Document 1 holds a program counter value in a register, a table that holds an address of a protection area on a memory, and a table that holds an address of an instruction permitted to access the protection area. The access detection circuit determines whether the instruction is an access instruction to the protection area based on the result of decoding the instruction and the comparison result between the address of the access destination and the address of the table. If an access instruction to the protection area is detected, it is prohibited when the comparison circuit compares the register and table addresses and determines that the instruction is read from an area where access to the protection area is not permitted. A signal is output to prohibit unauthorized memory access.

The technique described in Patent Document 2 is to check program data stored in a ROM of a gaming machine using a ROM checker.
JP-A-10-228421 JP 11-333108 A

  However, in the technique described in Patent Document 1, since the instruction code string is decoded and the program counter value is read, the process of the illegal operation detection process becomes complicated, and the difficulty of development and design increases. There was a problem.

  Further, the technique described in Patent Document 2 has a problem in that since the check is performed by connecting a ROM checker each time, it cannot be performed while the gaming machine is in operation, and the check operation is not easy. Although it is conceivable to provide an illegal operation detection process corresponding to the function of the ROM checker and perform a check at the time of starting or operating the gaming machine, it is necessary to prepare a table having the same capacity as the ROM for the check. However, for gaming machines, the data capacity for the control program is strictly limited by law, so it is not practical to have such a large capacity table.

  Therefore, the present invention has been made paying attention to such an unsolved problem of the conventional technology, and prevents unauthorized operation without increasing the difficulty of development and design and the data capacity. It is an object of the present invention to provide a game machine, an access control program, and a game control method suitable for the above.

  [Invention 1] In order to achieve the above object, a gaming machine of Invention 1 is a gaming machine comprising a main control board that performs main control of a game, and a peripheral board that operates under the control of the main control board, The main control board includes a lottery means for performing lottery upon the establishment of a predetermined condition, a variable display control means for performing variable display of the symbols on the symbol display means, and a predetermined result based on a lottery result of the lottery means. A special state generating means for generating a special state after stopping the symbol in the mode, and a data processing device for processing data relating to a game, the data processing device specifying data processing means and power-on Transmitting means for transmitting a power-on command to the peripheral board, and output means for outputting information relating to an instruction executed by the data processing means to the outside in association with the power-on command And the peripheral board has a receiving means for receiving the power-on command, and the gaming machine further includes an access control device that controls access by the data processing device, and the access control device includes the data Storage means for storing data for processing, input means for inputting information relating to the instruction from the output means, and information relating to the instruction input by the input means to the storage means by the data processing device Access control means for controlling the access.

  With such a configuration, in the data processing device of the main control board, when the power is turned on, the power-on command is transmitted to the peripheral board by the transmission means.

  In the peripheral board, the power-on command is received by the receiving means.

  In the data processing device of the main control board, the output unit outputs information related to the command executed by the data processing unit in association with the power-on command.

  In the access control device, information related to the command is input by the input unit, and the access control unit controls access to the storage unit by the data processing device based on the information related to the input command.

  This reduces the possibility that the data in the storage means will be illegally rewritten or read out.

  On the main control board, when a game is started and a predetermined condition is satisfied, the lottery means performs lottery with this as a trigger. Further, the variable display control means performs control to display the symbols in a variable manner by the symbol display means. Then, the special prize state is generated by the special prize state generating means after the symbol is stopped in a predetermined manner based on the lottery result of the lottery means.

  As described above, the power-on command is transmitted when the gaming machine is initialized, such as when the gaming machine is turned on or reset. Initialization is classified into a different category from game control. Therefore, if the access control device is accessed during initialization, the process (man-hours) required for program design and testing can be reduced compared with the case where access is performed during game control. This is advantageous in terms of quality control.

  In addition, since access control is performed at the time of initialization that is at the time of transmission of a power-on command, for example, even if cheating is performed after the pachinko hall closes, cheating is detected before the player enters the store Can do.

  In addition, since the access control device is accessed when the power-on command is transmitted, the processing load on the main control board and the peripheral board can be reduced as compared with the case where the access is performed every time each command is transmitted. Therefore, the present invention can also be applied to a gaming machine in which the main control board or the peripheral board does not have a high processing capacity or a gaming machine having a large processing load.

  Here, as the information regarding the instruction, for example, (1) instruction code or instruction code string, (2) storage position information (for example, address) indicating the storage position of the instruction code or instruction code string, (3) instruction code or Execution result information indicating the execution result of the instruction code string (for example, the value of the flag register), or (4) secondary information obtained based on one or a plurality of pieces of information (for example, operation information obtained by operation or the like) ) Is included. Hereinafter, the same applies to the gaming machine of the invention 2, the access control program of the invention 11, and the game control methods of the inventions 12 and 13.

  As for “control” of access, for example, (1) when it is determined that an access permission condition is established based on information on an instruction or secondary information obtained based on the information, a part or all of the access is permitted. If it is determined that the access permission condition is not satisfied, the access restriction condition is satisfied based on information related to the instruction or secondary information obtained based on the information, or (2) restricting part or all of the access. When it is determined, part or all of the access is restricted, and when it is determined that the access restriction condition is not satisfied, permitting part or all of the access is included. As the access permission condition or the access restriction condition, for example, (1) information related to the instruction or secondary information obtained based on the information is within a predetermined value, content, or range, and (2) information related to the instruction or the information It is included that the secondary information obtained based on is not within a predetermined value, content or range. As for “restriction” of access, for example, (1) prohibiting a part or all of access, and (2) controlling so that an access result corresponding to the access request cannot be obtained (for example, access request Read or write data different from the related data).

  Regarding the relationship between the instruction in the information related to the instruction and the access control, for example, (1) based on the information related to the instruction executed by the data processing means for accessing the storage means, the access related to the instruction is performed. (2) Controlling access related to an instruction executed by the data processing means for accessing the storage means before or after the instruction based on information relating to the instruction executed by the data processing means. Is included. In the case of (2), the causal relationship is difficult to understand, and the possibility of fraudulent acts can be further reduced. Hereinafter, the same applies to the gaming machine of the invention 2, the access control program of the invention 11, and the game control methods of the inventions 12 and 13.

  In addition, for example, information relating to an instruction may be associated with a rule relating to output or input of a power-on command by adding information related to the instruction to the power-on command (for example, a predetermined time after the power-on command is output). Output information about the instruction (after the elapse of time), add access information (eg, link information) necessary to access the information about the instruction to the power-on command, and access according to the rules related to the output or input of the power-on command Transmitting information is included.

A special winning opening 109 is provided. When the jackpot lottery results in a “hit” (hereinafter simply referred to as “hit”), the opening and closing members installed on the entire surface of the big winning opening 109 repeat the opening and closing operation. While the open / close member is open, a large number of game balls are received. When a game ball wins the big winning opening 109, a predetermined number (for example, 10) of game balls is paid out as a prize ball for each game ball. The opening of the special winning opening 109 continues until a predetermined time (for example, 30 seconds) elapses or a predetermined number (for example, 10) of game balls wins. One opening period of the big prize opening 109 is called a round, and the round continues a maximum of a predetermined number of times (hereinafter referred to as the maximum number of rounds).

Communication with the production control unit 300 is one direction from the main control unit 200 to the production control unit 300. In contrast, communication with the prize ball control unit 400 is bidirectional.

  The big prize opening opening / closing unit 288 can be configured using, for example, a solenoid. The jackpot is pre-programmed to occur with a predetermined probability (for example, 1/300) based on the jackpot random number.

  The effect control unit 300 receives a control command from the main control unit 200 and performs an effect control of the game based on the received control command. The effect control unit 300 includes a ROM 304 that stores a control program, a CPU 302 that executes an effect control process according to the control program stored in the ROM 304, a RAM 306 that functions as a data work area during the calculation process of the CPU 302, and a display on the symbol display unit 104.

For example, the prize ball control unit 400 may be provided on the same printed circuit board as the main control unit 200.

[Configuration of main controller]
Next, the configuration of the main control unit 200 will be described.

  FIG. 3 is a block diagram illustrating a configuration of the main control unit 200.

As shown in FIG. 3, the main control unit 200 is a DIP (Dual Inline
CPU 202, which is a one-chip type microprocessor composed of a package), an access control device 230 for controlling access by the CPU 202, and an inspection port 240 used for a pachinko machine verification test.

  The CPU 202 includes a ROM 204 that stores a control program, a CPU core 203 that executes game control processing in accordance with the control program stored in the ROM 204, a RAM 206 that functions as a data work area when the CPU core 203 performs arithmetic processing, and an inspection port 240. And a security inspection circuit 208 that outputs an instruction code string executed by the CPU core 203 and other inspection data.

  The CPU 202 further includes I / Fs 210 and 212 that perform input / output with an external device, and a timer 214 that measures time. The CPU core 203, ROM 204, RAM 206, security inspection circuit 208, I / Fs 210 and 212, and timer 214 are connected to each other via a bus 216.

  The RAM 206 stores input / output data for the main control unit 200, data for arithmetic processing, a random number counter for generating random numbers and other various counters, a jackpot flag and other various flags, and the number of reserved balls. The contents of the RAM 206 are retained even when the power is shut off by a backup power source (not shown).

  The random number counter is a random number used for lottery lottery (a jackpot determined random number), a random number for determining the stop mode of the effect symbol (stop symbol determined random number), and a random number for determining the variation pattern of the effect symbol (variation pattern determining random number) A random number (reach determination random number) for determining the presence or absence of an effect (hereinafter referred to as a reach effect) for making a jackpot notice by stopping a part of the effect symbol at a reach symbol (eg, “77”), and other games It is provided corresponding to each random number used for control. In addition, the number of reserved balls is the number of game balls won in the start winning opening 105, and means that the big hit lottery is not performed.

  An access control device 230 is connected to the I / F 212. Due to its hardware structure, the CPU 202 does not output address signals, data signals, and control signals transmitted / received via the bus 216 to the outside. Further, since the signal line of the bus 216 is built in the CPU 202, it is difficult to directly connect the access control device 230 to the signal line of the bus 216 because it requires modification. Therefore, in the configuration as it is, the access control device 230 cannot acquire information related to an instruction executed by the CPU core 203. Therefore, in the present embodiment, as information relating to instructions executed by the CPU core 203, an instruction code string executed by the CPU core 203 and an address (hereinafter simply referred to as an address) in the ROM 204 are transmitted via the I / F 212. The CPU core 203 is caused to execute the output process. This output process can be incorporated as one process of the control program in the ROM 204, for example. Thereby, the access control device 230 can input the instruction code string executed by the CPU core 203 and its address from the I / F 212. Here, the address of the instruction code string refers to the address of the first instruction code in the instruction code string.

  In addition to the CPU 302, ROM 304, RAM 306, VRAM 308, and I / F 310, the effect control unit 300 includes an effect-related device group 314 including a plurality of devices necessary for game effect control. Similarly, the prize ball control unit 400 includes a prize ball related device group 414 including a plurality of devices required for game ball payout control, in addition to the CPU 402, the ROM 404, the RAM 406, and the I / F 410.

[Data structure of control command]
Next, the data structure of the control command will be described.

  FIG. 4 is a diagram illustrating the data structure of a normal control command and a control command with an instruction code string.

  The normal control command is a control command other than the power-on command, and includes only the control command 500 as shown in FIG. On the other hand, the control command with instruction code string is formed by adding an instruction code string 502 executed by the CPU core 203 and its address 504 to the control command 500 which is a power-on command.

  FIG. 5 is a diagram illustrating the data structure of the control command 500.

  As shown in FIG. 5, the control command 500 includes a mode (MODE) that is an identifier for identifying the control command 500 and an event (EVENT) that is data indicating the specific execution contents of the control command 500. . A mode identification number of 1 byte length is set for the mode, and an event number of 1 byte length is set for the event.

  FIG. 6 is a diagram illustrating the contents of the control command transmitted from the main control unit 200.

  As shown in FIG. 6, the control commands include a power-on command, a power-off command, a customer waiting demo command, a customer waiting demo stop command, a variation pattern command, a jackpot start command, a jackpot end command, and a jackpot command.

  The power-on command is a control command for designating power-on, and is transmitted to the effect control unit 300 and the prize ball control unit 400 when the power is turned on. An instruction code sequence executed by the CPU core 203 and its address are added to the power-on command.

  The power-off command is a control command for designating power-off, and is transmitted to the effect control unit 300 and the prize ball control unit 400 when the power is turned off.

  The customer waiting demo command is a control command for designating the start of a demonstration effect (hereinafter referred to as a customer waiting demo) for attracting a player, and is transmitted to the effect control unit 300 when the game is interrupted.

  The customer waiting demo stop command is a control command for designating the end of the customer waiting demo, and is transmitted to the effect control unit 300 when the game is resumed.

  The variation pattern command is a control command for designating the variation pattern of the effect symbol, and is transmitted to the effect control unit 300 when the variation of the effect symbol is started. The variation pattern commands include an outlier non-reach command, an outlier reach command, and a jackpot reach command.

  The non-reach non-reach command is a control command for designating a change pattern that does not perform reach among the change patterns that are selected when the big hit lottery results in “out” (hereinafter, simply referred to as “out”). .

  The detachment reach command is a control command for designating a variation pattern for performing a reach effect among the variation patterns selected at the time of detachment. The effect control unit 300 can determine that there is a loss based on a loss reach command or a loss non-reach command.

  The jackpot reach command is a control command for designating a variation pattern for performing a reach effect among the variation patterns selected at the time of the jackpot. The effect control unit 300 can determine that the jackpot is based on the jackpot reach command.

  The jackpot start command is a control command for designating the start of the jackpot effect, and is transmitted to the effect control unit 300 at the start of the jackpot effect.

  The jackpot end command is a control command for designating the end of the jackpot effect, and is transmitted to the effect control unit 300 at the end of the jackpot effect (at the end of the final round).

  The jackpot command is a control command for designating a jackpot, and includes a round start command and a round end command.

  The round start command is a control command for designating the start of a round, and is transmitted to the effect control unit 300 at the start of the round. The round start command is set for each round. For example, when the maximum number of rounds is 15, 15 types of round start commands are set. Accordingly, when the round continues twice or more, the round start command is transmitted a plurality of times during the jackpot.

  The round end command is a control command for designating the end of the round, and is transmitted to the effect control unit 300 at the end of the round excluding the final round. The round end command is set for each round except the final round. For example, when the maximum number of rounds is 15, 14 types of round end commands are set. Therefore, when the round continues three or more times, the round end command is transmitted a plurality of times during the jackpot.

  These control commands are merely representative, and various other control commands are defined.

[Configuration of CPU core and access control device]
Next, the configuration of the CPU core 203 and the access control device 230 will be described.

  FIG. 7 is a block diagram showing the configuration of the CPU core 203 and the access control device 230. In FIG. 7, a part of the configuration is omitted for convenience of explanation.

  As shown in FIG. 7, the CPU core 203 reads (fetches) the instruction code sequence stored in the ROM 204 and performs data processing according to the read instruction code sequence. The CPU core 203 includes a control unit 203a, a calculation unit 203b, and a register 203c.

  The control unit 203a controls the overall operation of the CPU 202 and outputs a control signal to the bus 216 in order to read and write instruction code strings and other data.

  The operation unit 203b performs an operation on the data held in the register 203c.

  The register 203c holds the instruction code string read from the ROM 204, its address, and the data processed by the arithmetic unit 203b.

  The access control device 230 includes an input unit 231, a calculation unit 232, registers 234 and 236, and an access control unit 238.

  The input unit 231 includes a latch circuit or the like, and inputs an instruction code string executed by the CPU core 203 and its address added to the power-on command from the I / F 212.

  The computing unit 232 generates authentication information necessary for authentication.

  The register 234 holds the authentication information generated by the calculation unit 232. Access to the register 234 is controlled by the access control unit 238.

  The register 236 holds data processed by the CPU core 203. Access to the register 236 is controlled by the access control unit 238.

  When the access control unit 238 inputs a read request to the registers 234 and 236, the access control unit 238 inputs a read command and its address related to the read request from the input unit 231, and the access permission condition is set based on the input read command and address. When it is determined that it is established, reading of data from the registers 234 and 236 is permitted. On the other hand, when it is determined that the access permission condition is not satisfied, reading of data from the registers 234 and 236 is prohibited. Specifically, the instruction code string input by the input unit 231 is a code string permitted in advance (hereinafter referred to as a permitted instruction code string), and the address of the instruction code string is an address permitted in advance. The data can be read from the registers 234 and 236 only when it is (hereinafter referred to as a permitted address).

  When the access control unit 238 inputs a write request to the register 236, the access control unit 238 inputs a write command and its address related to the write request from the input unit 231, and the access permission condition is satisfied based on the input write command and address. When the determination is made, writing of data to the register 236 is permitted. On the other hand, when it is determined that the access permission condition is not satisfied, data writing to the register 236 is prohibited. Specifically, data can be written into the register 236 only when the instruction code string input from the input unit 231 is a permitted instruction code string and the address of the instruction code string is a permitted address.

[Access control processing]
Next, an access control process executed by the access control unit 238 will be described.

  FIG. 8 is a flowchart showing the access control process.

  When executing the access control process, the access control unit 238 first proceeds to step S100 as shown in FIG.

  In step S100, it is determined whether or not a read request for the registers 234 and 236 is input from the I / F 212. When it is determined that a read request is input (Yes), the process proceeds to step S102.

  In step S102, it is determined whether or not a power-on command is input from the I / F 212. When it is determined that a power-on command is input (Yes), the process proceeds to step S104, but when it is determined that it is not ( No) waits in step S102 until a power-on command is input.

  In step S104, the instruction code string executed by the CPU core 203 and its address are input from the input unit 231 and the process proceeds to step S106.

  In step S106, it is determined whether or not the input instruction code string is a permitted instruction code string. When it is determined that the input instruction code string is a permitted instruction code string (Yes), the process proceeds to step S108, and the input address is permitted. It is determined whether the address is an address, and when it is determined that the address is a permitted address (Yes), the process proceeds to step S110.

  In step S110, the data held in the registers 234 and 236 are read, the process proceeds to step S112, and the read data is output to the I / F 212. The output data is held in the register 203c of the CPU core 203 via the I / F 212.

  Next, the process proceeds to step S114, where it is determined whether a write request for the register 236 is input from the I / F 212. When it is determined that a write request is input (Yes), the process proceeds to step S116.

  In step S116, it is determined whether a power-on command is input from the I / F 212. When it is determined that the power-on command is input (Yes), the process proceeds to step S118, but when it is determined that it is not ( No) waits in step S116 until a power-on command is input.

  In step S118, the instruction code string executed by the CPU core 203 and its address are input from the input unit 231 and the process proceeds to step S120.

  In step S120, it is determined whether or not the input instruction code string is a permitted instruction code string. When it is determined that the input instruction code string is a permitted instruction code string (Yes), the process proceeds to step S122, and the input address is permitted. It is determined whether or not it is an address, and when it is determined that the address is a permitted address (Yes), the process proceeds to step S124.

  In step S124, the data held in the register 203c of the CPU core 203 is input from the I / F 212, the process proceeds to step S126, the input data is written in the register 236, and the access control process ends.

  On the other hand, when it is determined at step S122 that the address is not a permitted address (No), when it is determined at step S120 that it is not a permitted instruction code string (No), and when it is determined at step S114 that a write request is not input (No). ) Terminates the access control process without writing data to the register 236. At this time, the CPU core 203 may receive a notification from the access control device 230 and may notify that there is a possibility of fraud (hereinafter referred to as fraud notification). For example, the fraud notification may be performed by displaying a predetermined message, mark, or image on the symbol display unit 104, outputting a predetermined message sound or sound effect from the speaker 380, or the manufacturer or administrator of the CPU 202 via the I / F 210. Alternatively, an error message can be transmitted to another device, or a control signal for causing the other device to perform the display or audio output can be transmitted via the I / F 210. As a result, the main control unit 200 can make the user or the like recognize that there is a possibility of fraud, and can take measures such as investigation and repair.

  On the other hand, when it is determined at step S108 that the address is not a permitted address (No), when it is determined at step S106 that it is not a permitted instruction code string (No), and when it is determined at step S100 that a read request is not input (No). In both cases, the data held in the registers 234 and 236 is not output to the I / F 212, and the process proceeds to step S114. At this time, since there is no output from the access control device 230, the register 203c of the CPU core 203 holds an invalid value such as “0000” or “1111”. If the non-legitimate value is set to a predetermined value and the value is held in the register 203c, the CPU core 203 may make an unauthorized notification. Here, the predetermined value is, for example, a plurality of types of fixed value groups or a variation value for which a variation rule has been defined in advance.

[ROM memory structure]
Next, the memory structure of the ROM 204 will be described.

  FIG. 9 is a diagram schematically showing the memory structure of the ROM 204.

  As shown in FIG. 9, the ROM 204 stores an instruction code string executed by the CPU core 203.

  An address is assigned to the storage area 204a of the ROM 204 for each predetermined area (for example, for each byte). In the example of FIG. 9, addresses “0x000” to “0xNNN” are assigned to the storage area 204a, and each address indicates an area of 1 byte. For example, an instruction code string “0xABCDEFGH” (read instruction) is stored at addresses “0x100” to “0x103”. In addition, an instruction code string “0xJKLMNOPQ” (write instruction) is stored at addresses “0x104” to “0x107”.

[Game control processing]
Next, game control processing executed by the CPU core 203 will be described.

  The CPU core 203 reads a control program capable of executing one cycle at a predetermined operation clock (for example, 4 [ms]) from the ROM 204, and executes the game control process shown in the flowchart of FIG. 10 according to the read control program.

  FIG. 10 is a flowchart showing the game control process.

  When the game control process is executed in the CPU core 203, first, the process proceeds to step S200 as shown in FIG.

  In step S200, it is determined whether or not the power is turned on. When it is determined that the power is turned on (Yes), the process proceeds to step S202. When it is determined that the power is not turned on (No), the power is turned on. It waits at step S200 until it turns on.

  In step S202, an initialization process is executed, the process proceeds to step S204, a winning determination process is performed to determine that a game ball has won the start winning opening 105, and the process proceeds to step S206.

  In step S206, the jackpot determination process for determining the jackpot and determining the variation pattern of the effect symbol is executed, and the process proceeds to step S208 to open the opening / closing member of the big winning opening 109 in a predetermined pattern. And the process proceeds to step S210.

  In step S210, a prize ball payout control process is executed in which a control command (payout control command) for designating game ball payout to the prize ball control unit 400 is stored in the transmission buffer of the RAM 206, and the process proceeds to step S212. Then, a control command transmission process for transmitting the control command stored in the transmission buffer to the effect control unit 300 or the prize ball control unit 400 via the I / F 210 is executed, and the process proceeds to step S214.

  In step S214, it is determined whether or not the power has been turned off. If it is determined that the power has been turned off (Yes), the process proceeds to step S216 and the effect control unit 300 and the award are received via the I / F 210. A termination process for transmitting a power-off command to the ball control unit 400 is executed, and the game control process is terminated.

  On the other hand, when it is determined in step S214 that the power is not turned off (No), the process proceeds to step S204.

  Note that the random number counter is updated using the remaining time during which each process is executed in one cycle (for example, 4 [ms]) of the operation clock. In addition, it can be updated by a random number update process executed in parallel with the game control process. For example, the random number counter counts up by “1” sequentially from “0”, and returns to “0” when the count value exceeds the maximum value (for example, “999”). Counting is performed cyclically in a range (for example, “0” to “999”).

[Initialization process]
Next, the initialization process in step S202 will be described.

  FIG. 11 is a flowchart showing the initialization process.

  When the initialization process is executed in step S202, as shown in FIG. 11, first, the process proceeds to step S300, the contents of the RAM 206 are initialized, and the process proceeds to step S304.

  In step S304, a connected device authentication process for authenticating a device connected to the CPU 202 (hereinafter referred to as a connected device) is executed, a series of processes are terminated, and the original process is restored.

[Device / PLC authentication processing]
Next, the connected device authentication process in step S304 will be described.

  Various devices can be connected to the CPU 202, but devices that are not approved by the user or manufacturer are illegally connected, causing the CPU 202 to malfunction, or the data in the ROM 204 to be altered or stolen. There is a fear. In order to prevent this, the CPU 202 authenticates the connected device. Since the access control device 230 is also closely related to the execution of the connected device authentication process, the operations of the CPU core 203 and the access control device 230 accompanying the execution of the connected device authentication process will be described here.

  FIG. 12 is a flowchart showing the operations of the CPU core 203 and the access control device 230 when the connected device authentication process is executed.

  As shown in FIG. 12, the CPU core 203 first determines whether or not the processing up to step S414 has been completed based on the flag of the RAM 206 through step S400. As a result, when it is determined that the processing up to step S414 has not been completed (No), authentication data is acquired from the connected device through steps S402 and S404, and the acquired authentication data is obtained via the I / F 212. Is used to output a verification value V generation request. The verification value V is a value used for authenticating the connected device. Note that the authentication data acquired in step S402 may be used as the verification value V as it is.

  Upon receiving the verification value V generation request, the access control device 230 generates the verification value V by the arithmetic unit 232 through step S406 and stores the verification value V in the register 234.

  Next, the CPU core 203 reads a read command for reading the verification value V from the register 234 of the access control device 230 from the ROM 204 through step S408, and executes the read command to read the register 234 via the I / F 212. A read request for is output. In addition, through step S410, the read command read and its address are added to the power-on command, output via the I / F 212, and transmitted to the effect control unit 300 via the I / F 210.

  When the read request is input, the access control device 230 inputs a power-on command through step S412 and inputs a read command and its address added to the power-on command. If it is a permitted instruction code string and a permitted address, the verification value V held in the register 234 is read, and the read verification value V is output to the I / F 212.

  When the verification value V is input, the CPU core 203 holds the input verification value V in the register 203c through step S414, stores a flag indicating that the processing up to step S414 is completed in the RAM 206, and performs a series of processing. End and return to the original process.

  On the other hand, when the CPU core 203 determines in step S400 that the processing up to step S414 has been completed (Yes), whether or not the processing through step S416 is completed up to the processing of step S422 based on the flag of the RAM 206. Determine whether. As a result, when it is determined that the processing up to step S422 has not been completed (No), a write command for writing the verification value V to the register 236 of the access control device 230 is read from the ROM 204 through step S418, and the read write command is read. As a result, a write request to the register 236 is output via the I / F 212. In addition, through step S420, the read write command and its address are added to the power-on command, and are output via the I / F 212 and transmitted to the effect control unit 300 via the I / F 210. Further, through step S422, the verification value V held in the register 203c in step S414 is output via the I / F 212. Then, a flag indicating that the processing up to step S422 has been completed is stored in the RAM 206, the series of processing is terminated, and the original processing is restored.

  When the write request is input, the access control device 230 inputs a power-on command through step S424, and inputs a write command added to the power-on command and its address. If it is a permitted instruction code string and a permitted address, the verification value V is input, and the input verification value V is written in the register 236.

  On the other hand, when the CPU core 203 determines in step S416 that the processing up to step S422 has been completed (Yes), whether or not the processing through step S426 is completed up to the processing of step S434 based on the flag of the RAM 206. Determine whether. As a result, when it is determined that the processing up to step S434 has not been completed (No), a request for generating the expected value P is output via the I / F 212 through step S428. The expected value P is a value used for verifying the verification value V.

  When the access control device 230 receives a generation request for the expected value P, the operation unit 232 generates the expected value P and stores it in the register 234 through step S430.

  Next, the CPU core 203 reads the read command for reading the expected value P from the register 234 of the access control device 230 from the ROM 204 through step S432, and executes the read command to read the register 234 via the I / F 212. A read request for is output. In addition, through step S434, the read instruction and the read address are added to the power-on command, output via the I / F 212, and transmitted to the effect control unit 300 via the I / F 210. Then, a flag indicating that the processing up to step S434 has been completed is stored in the RAM 206, a series of processing is terminated, and the original processing is restored.

  When a read request is input, the access control device 230 inputs a power-on command through step S436, and inputs a read command and its address added to the power-on command. If it is a permitted instruction code string and a permitted address, the expected value P held in the register 234 is read, and the read expected value P is output to the I / F 212.

  On the other hand, when the CPU core 203 determines in step S426 that the processing up to step S434 has been completed (Yes), it passes through step S438 and ends up to the processing of steps S450 and S452 based on the flag of the RAM 206. It is determined whether or not. As a result, when it is determined that the processing of steps S450 and S452 has not been completed (No), the read instruction for reading the verification value V from the register 236 of the access control device 230 is read from the ROM 204 and read through step S440. By executing the read command, a read request for the register 236 is output via the I / F 212. Further, through step S442, the read instruction and the address read are added to the power-on command, output via the I / F 212, and transmitted to the effect control unit 300 via the I / F 210.

  When a read request is input, the access control device 230 inputs a power-on command through step S444, and inputs a read command and its address added to the power-on command. If it is a permitted instruction code string and a permitted address, the verification value V held in the register 236 is read, and the read verification value V is output to the I / F 212.

  When the verification value V and the expected value P are input, the CPU core 203 compares the verification value V with the expected value P through steps S446 and S448, and determines whether the verification result is correct. Whether or not the collation result is correct is determined based on, for example, whether or not the verification value V has a predetermined relationship with the expected value P. The predetermined relationship is, for example, that the verification value V matches the expected value P, that the calculation value obtained by calculating one of the verification value V and the expected value P by a predetermined calculation method matches the other, This means that the value V and the expected value P have a magnitude relationship and other correlations.

  When it is determined that the collation result is correct (Yes), the CPU core 203 authenticates the connected device through step S450, stores a flag indicating that the processing up to step S450 is completed in the RAM 206, and performs a series of processing. End and return to the original process. On the other hand, when it is determined that the collation result is not correct (No), the CPU core 203 stores, in the RAM 206, a flag indicating that the connected device has not been authenticated through step S452 and the processing up to step S452 has been completed. A series of processing is terminated and the original processing is restored. When the connected device is not authenticated, the CPU core 203 performs fraud notification or disconnects the connection with the connected device.

  On the other hand, when the CPU core 203 determines in step S438 that the processing up to steps S450 and S452 has been completed (Yes), the power-on command is directly sent via the I / F 210 via step S454. To 300.

[Winning determination process]
Next, the winning determination process in step S204 will be described.

  FIG. 13 is a flowchart showing a winning determination process.

  When the winning determination process is executed in step S204, the process first proceeds to step S500 as shown in FIG.

  In step S500, it is determined whether or not the number of reserved balls is “0”, and when it is determined that the number of reserved balls is “0” (Yes), the process proceeds to step S502.

  In step S502, it is determined whether or not a predetermined time (for example, 10 minutes) has elapsed since the last winning to the start winning opening 105 using the timer 214, and when it is determined that the predetermined time has elapsed (Yes). Then, the process proceeds to step S504.

  In step S504, a customer waiting demonstration execution process for performing a customer waiting demonstration is executed. In the customer waiting demo execution process, the customer waiting demo is started by storing the customer waiting demo command in the transmission buffer. Further, when the resumption of the game is detected in response to winning at the start winning opening 105, an operation on the launching unit 482, etc., the customer waiting demo is terminated by storing a customer waiting demo stop command in the transmission buffer. Thereby, in the control command transmission process of step S212, a customer waiting demo command or a customer waiting demo stop command is transmitted to the effect control unit 300.

  Next, the process proceeds to step S506, where the sensor signal from the start winning opening detection unit 280 is read via the I / F 210, and whether it is detected that a game ball has won the start winning opening 105 based on the read sensor signal. If it is determined whether or not the winning of the game ball is detected (Yes), the process proceeds to step S508.

  In step S508, it is determined whether or not the number of retained balls is “4” or more, and when it is determined that the number of retained balls is less than “4” (No), the process proceeds to step S510, and the number of retained balls is determined. “1” is added to, and the process proceeds to step S512.

  In step S512, the jackpot determined random number, stop symbol determined random number, and other random numbers used for game control are acquired from the random number counter, and the process proceeds to step S514, where each acquired random number is stored in a predetermined area of the RAM 206 corresponding to the number of reserved balls. Store, end a series of processing, and return to the original processing.

  On the other hand, when it is determined in step S508 that the number of held balls is “4” or more (Yes) and when it is determined in step S506 that a winning of a game ball is not detected (No), a series of processing is performed. To return to the original process.

  On the other hand, when it is determined in step S502 that the predetermined time has not elapsed (No) and when it is determined in step S500 that the number of reserved balls is not “0” (No), the process proceeds to step S506. .

[Big hit judgment processing]
Next, the jackpot determination process in step S206 will be described.

  FIG. 14 is a flowchart showing the jackpot determination process.

  In the jackpot determination process, in order to generate a jackpot with a predetermined probability, one jackpot value is set in a predetermined numerical range (for example, “0” to “400”) that can be taken by the jackpot determination random number, and the start winning hole 105 14 is a process for obtaining a jackpot decision random number at the winning timing when the game ball is won and generating the jackpot when the acquired random number value matches the jackpot value, and when executed in step S206, First, the process proceeds to step S600.

  In step S600, it is determined whether or not the effect symbol is changing in the symbol display unit 104. When it is determined that the effect symbol is not changing (No), the process proceeds to step S602, and the number of reserved balls is “1”. When it is determined whether or not the number is equal to or greater than “1” or more (Yes), the process proceeds to step S604.

  In step S604, a jackpot determination random number is read from a predetermined area of the RAM 206 corresponding to the number of reserved balls, and the process proceeds to step S606 to determine whether or not the read random number value matches the jackpot value. When it is determined that it has been done (Yes), the process proceeds to step S608, the jackpot flag is set, and the process proceeds to step S610.

  In step S610, a big-hit stop symbol determination process is executed to determine the mode of the effect symbol to be stopped at the big-hit. In the jackpot stop symbol determination process, for example, a jackpot stop symbol determination table is read from the ROM 204. Then, a stop symbol determination random number is read from a predetermined area of the RAM 206 corresponding to the number of reserved balls, a stop symbol number of the order of the read random number value is acquired from the read stop symbol determination table, and control indicating the acquired stop symbol number Store the command (designation command) in the transmission buffer.

  Next, the process proceeds to step S612, and the big hit hour fluctuation pattern determination process is executed for determining the fluctuation pattern of the effect symbol to be displayed in a variable manner at the big hit. In the jackpot variation pattern determination process, for example, a reach determination random number is acquired from a random number counter, and a variation pattern determination table for jackpot corresponding to the acquired random number value is read from the ROM 204. Since the jackpot reach command is registered only in one or a plurality of specific variation pattern determination tables, this selection based on the reach determination random number determines whether or not to perform the reach effect. Then, the fluctuation pattern determination random number is obtained from the random number counter, the fluctuation pattern number of the order of the obtained random number value is obtained from the read fluctuation pattern determination table, and the fluctuation pattern command indicating the obtained fluctuation pattern number is stored in the transmission buffer. To do. As a result, in the control command transmission process of step S212, the big hit reach command and other variation pattern commands selected at the time of the big hit are transmitted to the effect control unit 300.

  Next, the process proceeds to step S614, and a symbol variation start process for storing in the transmission buffer a control command (variation start command) for designating the variation start of the effect symbol to the effect control unit 300 is executed, and the process proceeds to step S616. Then, “1” is subtracted from the number of held balls, a series of processing is terminated, and the original processing is restored.

  On the other hand, when it is determined in step S606 that it does not match the jackpot value (No), the process proceeds to step S618, and a stoppage stop symbol determination process for determining an aspect of the effect symbol to be stopped at the time of disconnection is executed. The off-time stop symbol determination process is configured in the same manner as in step S610. The difference from step S610 is that a stop symbol determination table for loss is used.

  Next, the process proceeds to step S620, and a variation pattern determination process at the time of detachment is performed to determine a variation pattern of the effect symbol that is variably displayed at the time of the separation. The deviation variation pattern determination processing is configured in the same manner as in step S612. The difference from step S612 is that a variation pattern determination table for deviation is used. As a result, in the control command transmission process of step S212, the variation non-reach command, the deviation reach command, and other variation pattern commands selected at the time of deviation are transmitted to the effect control unit 300.

  When the process of step S620 ends, the process proceeds to step S614.

  On the other hand, when it is determined in step S600 that the effect symbol is changing in the symbol display unit 104 (Yes), the process proceeds to step S622.

  In step S622, it is determined whether or not a predetermined time (for example, 30 seconds) has elapsed since the start of the change in the effect design. If it is determined that the predetermined time has elapsed (Yes), the process proceeds to step S624. The symbol stop process for storing in the transmission buffer a control command (design stop command) for designating the stop of the effect symbol to the effect control unit 300 is executed, and the series of processes is terminated and the original process is restored. Let

  On the other hand, when it is determined in step S622 that the predetermined time has not elapsed (No) and when it is determined in step S602 that the number of reserved balls is “0” (No), a series of processing is performed. End and return to the original process.

Next, the electric accessory control process in step S208 will be described.

  FIG. 15 is a flowchart showing the electric accessory control process.

  When the electric accessory control process is executed in step S108, the process first proceeds to step S700 as shown in FIG.

  In step S700, it is determined whether or not the jackpot is based on the jackpot flag, and when it is determined that the jackpot flag is set because the jackpot flag is set (Yes), the process proceeds to step S702.

  In step S702, it is determined whether or not it is time to start the jackpot effect. If it is determined that it is time to start the jackpot effect (Yes), the process proceeds to step S704.

  In step S704, a jackpot presentation start process for storing the jackpot start command in the transmission buffer is executed, a series of processes are terminated, and the process returns to the original process. Thereby, in the control command transmission process of step S212, the big hit start command is transmitted to the effect control unit 300.

  On the other hand, when it is determined in step S702 that it is not the timing to start the jackpot effect (No), the process proceeds to step S706, where it is determined whether it is the timing to start the round, and the timing to start the round. (Yes), the process proceeds to step S708.

  In step S708, a round start process for storing a round start command in the transmission buffer is executed, a series of processes are terminated, and the original process is restored. Thereby, in the control command transmission process of step S212, the round start command is transmitted to the effect control unit 300.

  On the other hand, when it is determined in step S706 that it is not the timing to start the round (No), the process proceeds to step S710, where it is determined whether the round is continuing, and it is determined that the round is continuing. If (Yes), the process proceeds to step S712.

  In step S712, a special prize opening / closing control process for controlling the opening / closing of the special prize opening 109 is executed by the special prize opening / closing unit 288, and a series of processes is terminated to return to the original process.

  On the other hand, when it is determined in step S710 that the round is not continuing (No), the process proceeds to step S714, where it is determined whether it is time to end the round, and it is determined that it is time to end the round. If yes (Yes), the process proceeds to step S716.

  In step S716, “1” is added to the number of rounds, and the process proceeds to step S718 to determine whether or not the number of rounds exceeds the maximum number of rounds (for example, 15 times). When it determines (No), it transfers to step S720.

  In step S720, a round end process for storing the round end command in the transmission buffer is executed, a series of processes are ended, and the original process is restored. Thereby, in the control command transmission process of step S212, the round end command is transmitted to the effect control unit 300.

  On the other hand, when it is determined in step S718 that the number of rounds exceeds the maximum number of rounds (Yes), the process proceeds to step S722.

  In step S722, a jackpot presentation end process for storing the jackpot end command in the transmission buffer is executed. Thereby, in the control command transmission process of step S212, a jackpot end command is transmitted to the effect control unit 300.

  Next, the process proceeds to step S724, where the jackpot flag is reset, the series of processes is terminated, and the original process is restored.

  On the other hand, when it is determined in step S714 that it is not the timing for ending the round (No) and in step S700, when it is determined that the big hit flag is not reset (No), a series of processing To return to the original process.

[Production control processing]
Next, the effect control process executed by the effect control unit 300 will be described.

  CPU302 reads a control program from ROM304, and performs the production | presentation control process shown in the flowchart of FIG. 16 according to the read control program.

  FIG. 16 is a flowchart showing the effect control process.

  When the effect control process is executed by the CPU 302, as shown in FIG. 16, first, the process proceeds to step S800.

  In step S800, a fluctuation pattern command reception process for receiving a fluctuation pattern command is executed, the process proceeds to step S802, a jackpot command reception process for receiving a jackpot command is executed, and the process proceeds to step S804.

  In step S804, other control command reception processing for receiving control commands other than the variation pattern command and jackpot command is executed, and the process proceeds to step S800.

Next, the fluctuation pattern command reception process in step S800 will be described.

  FIG. 17 is a flowchart showing the variation pattern command reception process.

  When the variation pattern command reception process is executed in step S800, as shown in FIG. 17, first, the process proceeds to step S900.

  In step S900, it is determined whether or not a variation pattern command has been received via the I / F 310. When it is determined that a variation pattern command has been received (Yes), the process proceeds to step S902, but it is determined that this is not the case. If (No), the process waits in step S900 until a variation pattern command is received.

  In step S902, a random number is acquired from a random number counter, the process proceeds to step S904, and one of a plurality of variation effects corresponding to the received variation pattern command is selected based on the acquired random number, and the process proceeds to step S906.

  Next, the process proceeds to step S908, where it is determined whether or not a predetermined time (for example, 30 seconds) has elapsed since the transmission of the change effect start command, and when it is determined that the predetermined time has not elapsed (No). Shifts to step S910 to determine whether or not a symbol stop command has been received via the I / F 310, and when it is determined that a symbol stop command has been received (Yes), shifts to step S912.

  In step S912, a variable effect end process for transmitting a control command (variable effect end command) for designating the end of the variable effect to the symbol display unit 104, the sound control unit 382, and the lamp control unit 386 is executed. .

  When the process of step S912 ends, the series of processes ends and the original process is restored.

  On the other hand, when it determines with not receiving a symbol stop command by step S910 (No), it transfers to step S908.

  On the other hand, when it is determined in step S908 that the predetermined time has elapsed (Yes), the process proceeds to step S912.

  The random number counter can be updated by the above method employed by the main control unit 200. However, the update method is not necessarily the same as that of the main control unit 200.

[Big hit command reception processing]
Next, the jackpot command reception process in step S802 will be described.

  FIG. 18 is a flowchart showing the jackpot command reception process.

  When the jackpot command reception process is executed in step S802, the process first proceeds to step S1000 as shown in FIG.

  In step S1000, it is determined whether a jackpot start command has been received via the I / F 310. If it is determined that a jackpot start command has been received (Yes), the process proceeds to step S1002.

  In step S1002, a jackpot effect start process for transmitting a control command (a jackpot effect start command) for designating the start of a jackpot effect to the symbol display unit 104, the sound control unit 382, and the lamp control unit 386 is executed. .

  Next, the process proceeds to step S1004, where it is determined whether a round start command is received via the I / F 310. When it is determined that a round start command is received (Yes), the process proceeds to step S1006.

  In step S1006, a round effect start process for transmitting a control command (round effect start command) for designating the start of the round effect to the symbol display unit 104, the sound control unit 382, and the lamp control unit 386 is executed. .

(Yes), the process proceeds to step S1014.

  In step S1014, a jackpot effect end process is executed to transmit a control command (a jackpot effect end command) for designating the end of the jackpot effect to the symbol display unit 104, the sound control unit 382, and the lamp control unit 386, respectively. Then, the series of processes is terminated and the original process is restored.

  On the other hand, when it is determined in step S1012 that the jackpot end command is not received (No), the process proceeds to step S1008.

  On the other hand, when it is determined in step S1004 that the round start command is not received (No), the process waits in step S1004 until the round start command is received.

  On the other hand, when it is determined in step S1000 that the jackpot start command is not received (No), the process waits in step S1000 until the jackpot start command is received.

[Operation of the present embodiment]
Next, the operation of the present embodiment will be described.

  First, when power is turned on to the pachinko machine, the main control unit 200 executes an initialization process through step S202. In the initialization process, a power-on command is transmitted. When the power-on command is transmitted, the connected device authentication process is executed through step S304.

  In the connected device authentication process, the connected device is authenticated by the access control device 230 through steps S402 to S454. At this time, the instruction code string executed by the CPU core 203 for accessing the access control device 230 and its address are added to the power-on command and output through steps S410, S420, S434, and S442. As a result, the validity of the connected device can be authenticated. However, for example, a connected device authentication process may be falsified by a malicious third party so that an unauthorized device is authenticated.

  For example, in step S424, the verification value V is written in the register 236 of the access control device 230. At this time, what is written in the register 236 is the verification value V originally held in the register 203 c of the CPU core 203. However, the value written to the register 236 can be set to a value stored in a place other than the register 203c (or an area other than the area where the verification value V is held in the register 203c) by an illegal instruction code string. It becomes.

  For example, in step S412, the verification value V is read from the register 234 of the access control device 230. At this time, the value to be read can be a value stored in a place other than the register 234 (or an area other than the area in the register 234 where the verification value V is held).

  These frauds can be made, for example, by branching the processing of the CPU core 203 by an illegal patch or the like.

  If such an illegal act is performed, a correct connection device authentication process cannot be performed, and an unauthorized device can be connected. Therefore, the main control unit 200 is provided with an access control device 230 and controls access to the registers 234 and 236 by the CPU 202. As a result, it is possible to reduce the possibility that an unauthorized device is authenticated by executing an unauthorized instruction code string.

  FIG. 19 is an explanatory diagram showing an outline of access control performed by the access control unit 238. In FIG. 19, a part of the configuration is omitted for convenience of explanation.

  As illustrated in FIG. 19, for example, it is assumed that the permitted instruction code sequence and the permitted address are an instruction code sequence “0xJKLMNOPQ” (write command) and an address “0x104”. At this time, the normal ROM 204 stores an instruction code string “0xJKLMNOPQ” (write instruction) at addresses “0x104” to “0x107”.

  When the CPU core 203 reads and executes the instruction code string “0xJKLMNOPQ” from the addresses “0x104” to “0x107” (arrow α), the access control unit 238 permits writing of data to the register 236.

  However, suppose that an illegal instruction code string “0xPOIYUTRE” (write instruction) has been written to addresses “0x200” to “0x203” as in unauthorized example 1, for example. In this case, even if the CPU core 203 reads and executes the instruction code string “0xPOIYUTRE” from the addresses “0x200” to “0x203” (arrow β), the address of the instruction code string is not a permitted address, so the access control unit 238 prohibits writing of data to the register 236 (deny write command).

  Further, for example, it is assumed that an illegal instruction code string “0xLKJHGFDS” is inserted into addresses “0x080” to “0x083” as in the illegal example 2. This illegal instruction code string is, for example, an instruction code string that changes a value written to the register 236. However, due to the insertion of this illegal instruction code string, the addresses of the instruction code string “0xJKLMNOPQ” (write instruction) that is originally permitted to be executed are “0x108” to “0x10B”.

  Therefore, even if the CPU core 203 reads and executes the instruction code string “0xJKLMNOPQ” from the addresses “0x108” to “0x10B” (arrow γ), the address of the instruction code string is not a permitted address, so the access control unit 238 Prohibits the writing of data to the register 236 (denies the write command). At this time, the CPU core 203 may receive a notification from the access control device 230 and perform an unauthorized notification. As a result, even if the write value is changed by execution of the illegal instruction code string “0xLKJHGFDS”, the value is not written to the register 236, so that the possibility of an illegal act can be reduced.

  On the other hand, the access control unit 238 can reduce the possibility that the CPU 202 malfunctions due to a bit error in addition to the above-mentioned fraudulent acts.

  FIG. 20 is an explanatory diagram showing an outline of access control performed by the access control unit 238.

  As illustrated in FIG. 20, for example, the permitted instruction code string and the permitted address are an instruction code string “0xABCDEFGH” (read instruction) and address “0x100”, and an instruction code string “0xABCDEFGI” (write instruction) and address “0x104”. ”. At this time, the regular ROM 204 stores an instruction code string “0xABCDEFGH” (read instruction) at addresses “0x100” to “0x103”.

  When the CPU core 203 reads the instruction code string, a bit error (for example, “1” becomes “0”) may occur in the instruction code string. As a result, the instruction code string “0xABCDEFGH” (read instruction) read from the addresses “0x100” to “0x103” by the CPU core 203 may be replaced with, for example, the instruction code string “0xABCDEFGI” (write instruction) ( Arrow δ). In this case, if the CPU core 203 executes the instruction code string “0xABCDEFGI” (write instruction), the data of the access control device 230 may be rewritten in an unexpected manner.

  However, even if such a write instruction is executed (arrow ε), the address of the instruction code string is not a permitted address, so the access control unit 238 prohibits writing of data to the register 236 (write instruction). Rejected).

  When the effect control unit 300 receives the power-on command, the effect display unit 104, the sound control unit 382, and the lamp control unit 386 receive the control command for the effect when the power is turned on (specifically, display of a demonstration screen). , The lighting of the lamp 384 and the control command for designating the output of sound) are transmitted respectively.

  When the initialization process is completed, the main control unit 200 repeatedly performs a winning determination process, a jackpot determination process, an electric accessory control process, and a control command transmission process at predetermined intervals through steps S204 to S212. As a result, the pachinko machine is in a playable state. A player can play a game by loading a rented game ball into a pachinko machine and operating the launch unit 482 to fire the game ball onto the game board 101.

  When the game ball launched by the player wins the start winning opening 105, the main control unit 200 obtains a jackpot determination random number at the winning timing through steps S506 and S512. Then, after steps S604 and S606, if the acquired random number value matches the jackpot value, the jackpot is won.

  When the jackpot is reached, the stop symbol mode and the variation pattern at the jackpot are determined through steps S610 and S612. At this time, when it is determined to perform the reach effect, in the control command transmission process, a symbol designation command for designating a jackpot symbol and a jackpot reach command are transmitted. Since the jackpot reach command is a control command other than the power-on command, the command code string and the address are not added to the effect control unit 300 as they are.

  When receiving the jackpot reach command, the effect control unit 300 performs steps S902 to S912 and executes processing when the jackpot reach changes based on the received jackpot reach command.

  In step S614 and S624, the main control unit 200 displays the effect symbols in a predetermined variation pattern, stops a portion of the effect symbols in the reach symbol, and then stops the effect symbol in the jackpot symbol. When the effect symbol stops, a jackpot start command is transmitted in the control command transmission process. Since the jackpot start command is a control command other than the power-on command, it is transmitted as it is to the effect control unit 300 without adding an instruction code string and an address.

  When the effect control unit 300 receives the jackpot start command, the process at the time of starting the jackpot effect is executed based on the received jackpot start command through step S1002.

  During the big hit, the round continues until the predetermined condition is satisfied with the maximum number of rounds as the upper limit. In the control command transmission process, a jackpot command is transmitted at the start and end of a round. Since the jackpot command is a control command other than the power-on command, it is transmitted as it is to the effect control unit 300 without adding an instruction code string and an address.

  When the effect control unit 300 receives the jackpot command, the process during the jackpot effect is executed based on the received jackpot command through steps S906 and S910.

  In addition, during the big hit, the big winning opening 109 is opened with a predetermined opening / closing pattern, and when a gaming ball wins the big winning opening 109, a predetermined number of gaming balls are paid out as one winning ball.

  When the final round ends, a jackpot end command is transmitted in the control command transmission process. Since the jackpot end command is a control command other than the power-on command, it is transmitted as it is to the effect control unit 300 without adding an instruction code string and an address.

  In the effect control unit 300, when the jackpot end command is received, the process at the end of the jackpot effect is executed based on the received jackpot end command through step S1014.

  On the other hand, if the random number obtained through steps S604 and S606 does not match the jackpot value, the result is a loss.

  When it comes off, through steps S618 and S620, the stop symbol mode and the fluctuation pattern at the time of loss are determined. At this time, when it is determined to perform the reach effect, in the control command transmission process, a symbol designating command and a missed reach command for designating a missed symbol (or an effect of becoming a missed symbol) are transmitted. On the other hand, when it is determined not to perform the reach effect, the symbol designation command and the off-reach non-reach command are transmitted in the control command transmission process. Since the outlier reach command or the outlier non-reach command is a control command other than the power-on command, the command code string and the address are not added to the effect control unit 300 as they are.

  In the production control unit 300, when an outlier reach command or an outlier nonreach command is received, through steps S902 to S912, processing at the time of deviation fluctuation is executed based on the received outlier reach command or outlier nonreach command.

  On the other hand, when the game is interrupted, the main control unit 200 executes a customer waiting demonstration execution process. In the control command transmission process, a customer waiting demo command is transmitted. Since the customer waiting demonstration command is a control command other than the power-on command, it is transmitted as it is to the effect control unit 300 without adding an instruction code string and an address.

  When the production control unit 300 receives the customer waiting demonstration command, the customer waiting demonstration control command is transmitted to the symbol display unit 104, the voice control unit 382, and the lamp control unit 386 as processing at the time of the customer waiting demonstration start. Is done.

  Thereafter, when the game is resumed, a customer waiting demonstration stop command is transmitted in the control command transmission process. Since the customer waiting demonstration stop command is a control command other than the power-on command, it is transmitted as it is to the effect control unit 300 without adding an instruction code string and an address.

  When the production control unit 300 receives the customer waiting demonstration stop command, a control command for the customer waiting demonstration is sent to the symbol display unit 104, the voice control unit 382, and the lamp control unit 386 as processing at the time of the customer waiting demonstration end. Sent.

[Effect of this embodiment]
In this way, in the present embodiment, the access control device 230 includes the registers 234 and 236, the input code 231 executed by the CPU core 203 and its address from the I / F 212, and the input module 231. And an access control unit 238 for controlling the access to the registers 234 and 236 by the CPU 202 based on the instruction code string and the address input in (1).

  This can reduce the possibility that the data in the registers 234 and 236 will be illegally rewritten or read out, thereby reducing the possibility that an illegal operation or an illegal operation due to an error will be performed. . In addition, since the access control device 230 that is separate from the CPU 202 realizes the access control function, the CPU core 203 itself does not need to perform unauthorized operation detection processing, and is more difficult to develop and design than in the past. It can be suppressed. Furthermore, since access is controlled based on the instruction code string and its address, it is not necessary to prepare a table having the same capacity as the ROM 204, and an increase in data capacity can be suppressed as compared with the conventional case.

  Further, in the case of adopting the CPU 202 that is a one-chip type microprocessor made of DIP or the like, in a configuration in which the CPU core 203 performs an unauthorized operation detection process, if an unauthorized action is performed such that the entire CPU 202 is replaced, the CPU Since the core 203 itself is exchanged, the validity of the CPU 202 cannot be authenticated. On the other hand, in this embodiment, since the access control device 230 is provided separately from the CPU 202, the legitimacy of the CPU 202 can be authenticated even if such an illegal act is performed.

  Further, in the case where the CPU 202 which is a one-chip type microprocessor made of DIP or the like is employed, the CPU 202 is newly developed, designed, etc. in the configuration in which the circuit for realizing the access restriction function of the access control device 230 is built in the CPU 202. And must not be applied to existing CPUs. On the other hand, in this embodiment, it is only necessary to connect the access control device 230 to the CPU 202, so that the present invention can also be applied to an existing CPU.

  Further, in the present embodiment, the main control unit 200 adds an instruction code sequence executed by the CPU core 203 for accessing the access control device 230 and its address to the power-on command and outputs it.

  As a result, the power-on command is transmitted during the initialization process of the pachinko machine, such as when the pachinko machine is powered on or reset. The initialization process is classified into a process category different from the game control process. Therefore, if the connected device is authenticated during the initialization process, the process (man-hours) required for program design and testing can be reduced compared to the case where authentication is performed during the game control process, and development costs and This is advantageous in terms of quality control.

  In addition, since the connected device is authenticated during the initialization process, which is the time when the power-on command is transmitted, for example, even if a fraudulent act is performed after the pachinko hall is closed, a fraudulent act is performed before the player enters the store. Can be detected. Therefore, it is possible to effectively reduce the possibility of fraud.

  Furthermore, since the connected device is authenticated when the power-on command is transmitted, the processing load on the main control unit 200 and the effect control unit 300 can be reduced as compared with the case where the authentication is performed every time each control command is transmitted. it can. Therefore, the present invention can also be applied to a pachinko machine in which the main control unit 200 or the production control unit 300 does not have a high processing capacity or a pachinko machine with a large processing load.

  Furthermore, since the instruction code string and address are added to the power supply command and output, the possibility of extracting the instruction code string and address from the communication data is greater than when the instruction code string and address are output alone. Can be reduced.

  Further, in the present embodiment, the access control unit 238 only registers the register 234 when the instruction code string input from the input unit 231 is a permitted instruction code string and the address of the instruction code string is a permitted address. 236 is permitted.

  As a result, an illegally rewritten instruction code string, an instruction code string whose contents have been changed due to a bit error, or an instruction code string stored at an illegal address are executed, whereby the data in the registers 234 and 236 are illegally stored. Since the possibility of being rewritten or read can be reduced, the possibility of an unauthorized operation can be further reduced.

  Further, in the present embodiment, fraud notification is performed according to the status of access control by the access control device 230.

  Thereby, it is possible to grasp that there is a possibility that an illegal operation has been performed.

  Further, in this embodiment, the access control device 230 is applied to the CPU 202 of the main control unit 200.

  Thereby, possibility that CPU202 of the main-control part 200 will operate | move illegally can be reduced. Since the main control unit 200 performs main control that is the basis of the game, the security effect is high.

[Second Embodiment]
Next, a second embodiment of the present invention will be described with reference to the drawings. FIG. 21 to FIG. 23 are diagrams showing a second embodiment of the gaming machine, the access control program, and the game control method according to the present invention.

  The present embodiment is based on the check value calculated from the instruction code string in addition to the instruction code string and its address executed by the CPU core 203, compared to the first embodiment. The point of controlling access is different. Hereinafter, only the parts different from the first embodiment will be described, and the same parts as those in the first embodiment will be denoted by the same reference numerals and the description thereof will be omitted.

[Configuration of main controller]
First, the configuration of the main control unit 200 will be described.

  FIG. 21 is a block diagram illustrating a configuration of the main control unit 200.

  As shown in FIG. 21, the CPU 202 includes a CPU core 203, ROM 204, RAM 206, security inspection circuit 208, I / F 210, 212, and timer 214, and a check value calculation unit 218 that calculates a check value from an instruction code string. Configured. These are connected to each other via a bus 216.

The check value calculation unit 218 acquires an instruction code string from the ROM 204. Then, a check value for checking the validity of the instruction code string is calculated from the acquired instruction code string. The check value is used for access control by the access control unit 238. Here, the check value is a value calculated from a part or all of the instruction code or instruction code string stored in the ROM 204, a part of one instruction code, or a combination thereof. The check value calculation unit 218, for example, performs an operation using a hash function, parity check, and cyclic redundancy check (CRC (Cyclic Redundancy) on all instruction code strings stored in the ROM 204.
Check)) or error detection calculation such as checksum is performed to calculate a check value. As described above, the check value is calculated from the instruction code string actually stored in the ROM 204. Therefore, by performing verification using the check value, it is possible to detect unauthorized rewriting of the instruction code sequence stored in the ROM 204, unauthorized replacement of the ROM 204, and the like.

  The input unit 231 inputs from the I / F 212 the instruction code sequence executed by the CPU core 203 and its address, which is added to the power-on command, and the check value calculated by the check value calculation unit 218. At this time, the check value may be divided and input. In this case, the check values are combined by combining the divided data.

  In the access control unit 238, the instruction code string input from the input unit 231 is a permitted instruction code string, the address of the instruction code string is a permitted address, and the check value input from the input unit 231 is a check value. Access to the registers 234 and 236 is permitted only when there is a predetermined relationship with the expected value. The predetermined relationship is, for example, that the check value matches the expected value, that the calculated value obtained by calculating one of the check value and the expected value by the predetermined calculation method matches the other, the check value and the expected value Means that there is a magnitude relationship or other correlation. In this way, by combining the collation of the instruction code string and address with the collation of the check value, the possibility of an illegal operation can be further reduced.

  The expected value used by the access control unit 238 for verification is stored in the access control unit 238 in advance (for example, at the time of manufacture). In addition, an expected value used for collation by the access control unit 238 may be transmitted to the access control unit 238 from another component unit. The other components are, for example, a CPU core 203 and a dedicated processing unit (hereinafter referred to as an expected value calculation unit) for generating an expected value of a check value. The CPU core 203 and the expected value calculation unit may transmit an expected value stored in advance to the access control unit 238, or may generate an expected value for each matching process. Further, a coefficient or the like necessary for calculating an expected value may be received from an external device via the I / F 210 to the CPU core 203 or the expected value calculation unit. As described above, if the expected value is not stored in advance in the access control unit 238 and is input from another component unit, the check value of the ROM 204 can be changed later.

[Check value calculation processing]
Next, a check value calculation process executed by the check value calculation unit 218 will be described.

  FIG. 22 is a flowchart showing the check value calculation process.

  When executing the check value calculation process, the check value calculation unit 218 first proceeds to step S1100 as shown in FIG.

  In step S1100, it is determined whether a check value acquisition request has been received from the access control unit 238. When it is determined that a check value acquisition request has been received (Yes), the process proceeds to step S1102, but this is not the case. (No), the process waits in step S1100 until a check value acquisition request is received.

  In step S1102, the instruction code string is read from the ROM 204, the process proceeds to step S1104, the above error detection calculation is performed on the read instruction code string, the check value is calculated, the process proceeds to step S1106, and the calculated check The value is transmitted to the access control unit 238, and the check value calculation process ends.

[Access control processing]
Next, an access control process executed by the access control unit 238 will be described.

  FIG. 23 is a flowchart showing the access control process.

  When executing the access control process, the access control unit 238 first proceeds to step S1200 as shown in FIG.

  In step S1200, it is determined whether or not a read request for the registers 234 and 236 is input from the I / F 212. When it is determined that a read request is input (Yes), the process proceeds to step S1202.

  In step S1202, it is determined whether or not a power-on command is input from the I / F 212. When it is determined that a power-on command is input (Yes), the process proceeds to step S1204, but when it is determined that it is not ( No) waits in step S1202 until a power-on command is input.

  In step S1204, the instruction code string executed by the CPU core 203 and its address are input from the input unit 231 and the process proceeds to step S1206.

  In step S1206, it is determined whether or not the input instruction code string is a permitted instruction code string. If it is determined that the input instruction code string is a permitted instruction code string (Yes), the process proceeds to step S1208, and the input address is permitted. It is determined whether or not it is an address, and when it is determined that the address is a permitted address (Yes), the process proceeds to step S1210.

  In step S1210, a check value acquisition request is transmitted to the check value calculation unit 218, the process proceeds to step S1212, the check value is input from the input unit 231 as a response, and the process proceeds to step S1214.

  In step S1214, the expected value of the check value is acquired by reading the expected value stored in the access control unit 238 or by receiving the expected value generated by the CPU core 203 or the expected value calculating unit. The process proceeds to step S1216.

  In step S1216, it is determined whether or not the input check value matches the input expected value. If it is determined that the check value matches the expected value (Yes), the process proceeds to step S1218.

  In step S1218, the data held in the registers 234 and 236 are read, the process proceeds to step S1220, and the read data is output to the I / F 212. The output data is held in the register 203c of the CPU core 203 via the I / F 212.

  Next, the process proceeds to step S1222, where it is determined whether a write request for the register 236 is input from the I / F 212. When it is determined that a write request is input (Yes), the process proceeds to step S1224.

  In step S1224, it is determined whether or not a power-on command is input from the I / F 212. When it is determined that a power-on command is input (Yes), the process proceeds to step S1226, but when it is determined that it is not ( No) waits in step S1224 until a power-on command is input.

  In step S1226, the instruction code string executed by the CPU core 203 and its address are input from the input unit 231 and the process proceeds to step S1228.

  In step S1228, it is determined whether or not the input instruction code string is a permitted instruction code string. When it is determined that the input instruction code string is a permitted instruction code string (Yes), the process proceeds to step S1230 and the input address is permitted. It is determined whether the address is an address, and when it is determined that the address is a permitted address (Yes), the process proceeds to step S1232.

  In steps S1232 to S1236, processing similar to that in steps S1210 to S1214 is executed, and the process proceeds to step S1238.

  In step S1238, it is determined whether or not the check value matches the expected value. If it is determined that the check value matches the expected value (Yes), the process proceeds to step S1240.

  In step S1240, the data held in the register 203c of the CPU core 203 is input from the I / F 212, the process proceeds to step S1242, the input data is written in the register 236, and the access control process ends.

  On the other hand, when it is determined at step S1238 that the check value does not match the expected value (No), when it is determined at step S1230 that it is not a permitted address (No), it is determined at step S1228 that it is not a permitted instruction code string. If it is determined (No) and if it is determined in step S1222 that the write request is not input (No), the access control process is terminated without writing data to the register 236. At this time, the CPU core 203 may receive a notification from the access control device 230 and perform an unauthorized notification.

  On the other hand, when it is determined in step S1216 that the check value does not match the expected value (No), when it is determined in step S1208 that it is not a permitted address (No), it is determined in step S1206 that it is not a permitted instruction code string. (No) and when it is determined in step S1200 that no read request is input (No), the data held in the registers 234 and 236 is not output to the I / F 212, and the process returns to step S1222. Transition. At this time, the illegal value is held in the register 203c of the CPU core 203. However, when the value is a predetermined value, the CPU core 203 may make an unauthorized notification.

[Effect of this embodiment]
Thus, in this embodiment, the CPU 202 includes the check value calculation unit 218 that calculates the check value from the instruction code string stored in the ROM 204, and the access control unit 238 receives the instruction code input from the input unit 231. Only when the column is a permitted instruction code string, the address of the instruction code string is a permitted address, and the check value input by the input unit 231 has a predetermined relationship with the expected value of the check value, the register 234 236 is permitted.

  Thereby, it can be detected that the instruction code string stored in the ROM 204 has been illegally rewritten. Further, by combining the collation of the instruction code string and address with the collation of the check value, the possibility of an illegal operation can be further reduced. Note that check value verification is performed in combination with instruction code string and address verification, so that even if an error detection operation (for example, parity check) with a relatively low processing load is used for calculation of the check value, a certain degree of accuracy can be obtained. Obtainable.

  In the second embodiment, the CPU 202 corresponds to the data processing device of the sixth aspect, the CPU core 203 corresponds to the data processing means of the sixth aspect, and the ROM 204 corresponds to the instruction code storage means of the sixth aspect. The check value calculation unit 218 corresponds to the calculation means of the sixth aspect. The input unit 231 corresponds to the input unit of the sixth aspect.

[Other Embodiments]
In the second embodiment, the access control device 230 is configured to calculate the check value from the instruction code string. However, the present invention is not limited to this, and the following three configurations can be employed.
(1) First Configuration In the first configuration, a check value is calculated from data stored in the ROM 204 (hereinafter referred to as first calculation basic data) instead of an instruction code string. The first calculation basic data is, for example, a predetermined fixed value stored in the ROM 204. The first calculation basic data is not limited to a fixed value, and may be fluctuation data that can accurately predict data values before and after the fluctuation. To be able to accurately predict the data values before and after the fluctuation specifically refers to, for example, a case where the fluctuation range is fixed or a fluctuation rule is fixed.

  The check value calculation unit 218 reads the first calculation basic data from the ROM 204 and calculates the check value from the read first calculation basic data.

  The access control unit 238 stores the expected value of the first calculation basic data in advance. The access control unit 238 calculates a check value from the expected value, and determines whether the check value input by the input unit 231 has a predetermined relationship with the calculated check value. In addition, it may be determined whether the check value input by the input unit 231 has a predetermined relationship with the expected value. Note that access control may be performed based on both the check value calculated from the instruction code string and the check value calculated from the first calculation basic data.

  As a result, it is possible to detect that the ROM 204 has been replaced with an illegal one.

In this case, the CPU 202 corresponds to the data processing apparatus of the seventh invention, the CPU core 203 corresponds to the data processing means of the seventh invention, the ROM 204 corresponds to the instruction code storage means of the seventh invention, and the check value calculation unit Reference numeral 218 corresponds to the calculating means of the seventh aspect. The input unit 231 corresponds to the input unit of the seventh aspect.
(2) Second Configuration In the second configuration, a check value is calculated from an execution result of an instruction code sequence executed by the CPU core 203 (hereinafter referred to as second calculation basic data) instead of an instruction code sequence. The second calculation basic data is, for example, the value of the flag register of the CPU core 203. Note that the second calculation basic data is not limited to the value of the flag register, and is a return value of a function that returns the first value when the instruction code string is correctly executed, and otherwise returns the second value. Also good.

  The check value calculation unit 218 acquires second calculation basic data from a flag register or the like, and calculates a check value from the acquired second calculation basic data.

  The access control unit 238 can be configured in the same manner as in the first configuration. Note that access control may be performed based on the check value calculated from the first calculation basic data.

  Further, the second calculation basic data may be used as it is without calculating the check value from the second calculation basic data. That is, the access control unit 238 has the instruction code string input from the input unit 231 as a permitted instruction code string, the address of the instruction code string is a permitted address, and the second calculation basic data is a predetermined value. Allow access only at certain times.

  As a result, there is a possibility that the data in the registers 234 and 236 may be illegally rewritten or read by executing an illegally rewritten instruction code string or an instruction code string whose contents have changed due to a bit error. Since it can reduce, possibility that an unauthorized operation will be performed can further be reduced.

In this case, the CPU core 203 corresponds to the data processing means of the eighth aspect, and the input unit 231 corresponds to the input means of the eighth aspect.
(3) Third Configuration In the third configuration, a check value is calculated from the address of the instruction code string (hereinafter referred to as third calculation basic data) instead of the instruction code string.

  The check value calculation unit 218 acquires third calculation basic data from the bus 216 or the like, and calculates a check value from the acquired third calculation basic data.

  The access control unit 238 can be configured in the same manner as in the first configuration. Note that access control may be performed based on a check value calculated from one or both of the first calculation basic data and the second calculation basic data.

  In the second embodiment, the access permission condition is that the instruction code string input by the input unit 231 is a permitted instruction code string, the address of the instruction code string is a permission address, and the input The check value input in the unit 231 has a predetermined relationship with the expected value of the check value. However, the present invention is not limited to this. (1) The instruction code string input in the input unit 231 is a permitted instruction code string. 2) that the address of the instruction code string is a permitted address, or (3) that the check value input by the input unit 231 has a predetermined relationship with the expected value of the check value, or any two combinations It can also be. Even when the first calculation basic data or the second calculation basic data is used, the access permission condition can be set in any combination with (1) to (3). Also in the first embodiment, the access permission condition can be set in (1) or (2).

In the first and second embodiments, the access control device 230 is provided in the main control unit 200. However, the present invention is not limited to this, and the following two configurations can be employed.
(1) First Configuration The first configuration is a configuration in which the access control device 230 is provided in the effect control unit 300.

  FIG. 24 is a block diagram showing the configuration of the effect control unit 300. As shown in FIG.

  As shown in FIG. 24, the effect control unit 300 includes a CPU 302 and an access control device 230.

  The CPU 302 is a one-chip type microprocessor composed of a DIP or the like, and an I / F 312 that performs input / output with an external device in addition to the CPU core 303, the ROM 304, the RAM 306, the VRAM 308, the I / F 310, and the effect related device group 314. It is comprised. These are connected to each other via a bus 316.

  The access control device 230 is connected to the I / F 312. Due to its hardware structure, the CPU 302 does not output address signals, data signals, and control signals transmitted / received via the bus 316 to the outside. Further, since the signal line of the bus 316 is built in the CPU 302, it is difficult to directly connect the access control device 230 to the signal line of the bus 316 because it requires modification. Therefore, in the configuration as it is, the access control device 230 cannot acquire information related to an instruction executed by the CPU core 303. Therefore, in the first configuration, the instruction code string executed by the CPU core 303 and the address in the ROM 304 are added to the power-on command received from the main control unit 200 as information related to the instruction executed by the CPU core 303. , The CPU core 303 executes processing to be output via the I / F 312. This output process can be incorporated as one process of the control program in the ROM 304, for example. As a result, the access control device 230 can input the instruction code string executed by the CPU core 303 and its address from the I / F 312.

  Thereby, possibility that CPU302 of the production | presentation control part 300 will operate | move illegally can be reduced.

In this case, the effect control unit 300 corresponds to the peripheral board of the second aspect.
(2) Second Configuration The second configuration is a configuration in which the access control device 230 is provided in the prize ball control unit 400.

  FIG. 25 is a block diagram illustrating a configuration of the prize ball control unit 400.

  As shown in FIG. 25, the prize ball control unit 400 includes a CPU 402 and an access control device 230.

  The CPU 402 is a one-chip type microprocessor composed of a DIP or the like, and includes an I / F 412 that performs input / output with an external device in addition to the CPU core 403, ROM 404, RAM 406, I / F 410 and prize ball related device group 414. It is configured. These are connected to each other via a bus 416.

  The access control device 230 is connected to the I / F 412. Due to its hardware structure, the CPU 402 is configured not to output address signals, data signals, and control signals transmitted / received via the bus 416 to the outside. Further, since the signal line of the bus 416 is built in the CPU 402, it is difficult to directly connect the access control device 230 to the signal line of the bus 416 because it requires modification. Therefore, in the configuration as it is, the access control device 230 cannot acquire information related to an instruction executed by the CPU core 403. Therefore, in the second configuration, the instruction code string executed by the CPU core 403 and the address in the ROM 404 are added to the power-on command received from the main control unit 200 as information related to the instruction executed by the CPU core 403. , The CPU core 403 executes processing to be output via the I / F 412. This output process can be incorporated as one process of the control program in the ROM 404, for example. As a result, the access control device 230 can input the instruction code string executed by the CPU core 403 and its address from the I / F 412.

  Thereby, possibility that CPU402 of the prize ball control part 400 will operate | move illegally can be reduced.

  In this case, the prize ball control unit 400 corresponds to the peripheral substrate of the second aspect.

  In the first and second embodiments, the access control unit 238 is configured to control access to the registers 234 and 236. However, the present invention is not limited to this, and a specific address of the registers 234 and 236 is used. It can also be configured to control access to the space.

  Thus, by controlling access to the address space in which important information such as confidential information is stored in the registers 234 and 236, the possibility that the important information is illegally rewritten or read is reduced. Therefore, the possibility of unauthorized operation can be further reduced.

  In the first and second embodiments, the read, execute, determination and other processes are performed in units of instruction code strings. However, the present invention is not limited to this, and read and execute in units of instruction codes. Further, it can be configured to perform determination and other processing. The same applies to the other embodiments described above. As a representative example, access is permitted only when the input instruction code is a previously permitted code and the address of the instruction code is a permitted address. For the combination of access permission conditions, the same combination as in the case of the instruction code string can be adopted.

  In the first and second embodiments, only one access control device 230 is provided. However, the present invention is not limited to this, and a plurality of access control devices 230 may be provided. In the case of two units, for example, the first access control device includes an input unit 231, a calculation unit 232, a register 234, and an access control unit 238. The second access control apparatus includes an input unit 231, a calculation unit 232, a register 236, and an access control unit 238. In this case, the access control unit 238 may be provided only in one of the access control devices.

  In the second embodiment, the check value calculation unit 218 is configured to calculate the check value in response to the check value acquisition request. However, the present invention is not limited to this, and the check value calculation unit 218 checks when a predetermined condition is satisfied. A value may be calculated, and the calculated check value may be transmitted to the access control unit 238.

  In the first and second embodiments, the CPU 202 is configured by providing the two I / Fs 210 and 212. However, the present invention is not limited thereto, and may be configured by providing only one I / F. However, a larger number of I / Fs may be provided. The same applies to the CPU 302 in FIG. 24 and the CPU 402 in FIG.

  In the first and second embodiments, the CPU 202 is configured to perform the connected device authentication process using the access control device 230. However, the present invention is not limited to this, and the access control device 230 is used. It can also be configured to obtain a random number. The same applies to the CPU 302 in FIG. 24 and the CPU 402 in FIG.

  In this case, the arithmetic unit 232 includes a random number generator or the like, and generates a random number used for game control and authentication information necessary for authentication. As the random numbers used for game control, a jackpot determined random number, stop symbol determined random number, variation pattern determined random number, reach determined random number, and other random numbers used for game control are generated.

  When a random number is read from the register 234 of the access control device 230, in the configuration in which the instruction code string and the address are added to the power-on command, the output timing of the instruction code string and its address may not match the random number read timing. . That is, the instruction code string and its address are output at the time of activation, whereas the jackpot determination random number must be read at the winning timing to the start winning opening 105. Thus, for example, the following two configurations can be adopted as the configuration of the access control device 230.

  In the first configuration, when authentication (instruction code string, address or check value coincidence determination result) is obtained when a control command is transmitted, authentication is not performed only for a predetermined number of permitted accesses. The predetermined permission count may start counting from the first access after the authentication is obtained, or may start counting after a predetermined number of accesses after the authentication is obtained. In the latter case, access before the start of counting is prohibited. Therefore, a predetermined number of dummy accesses are required after authentication. If this number is not known, access to the registers 234 and 236 cannot be made even if authentication is obtained, so that the possibility of unauthorized operation can be reduced. .

  In the second configuration, when authentication is obtained when the control command is transmitted, authentication is not performed only within a predetermined permission period. The predetermined permission period may be started immediately after the authentication is obtained, or may be started after a predetermined time has elapsed after the authentication is obtained. In the latter case, access before starting is prohibited. Further, when there is an access before the start, subsequent access may be prohibited. Therefore, it is necessary to wait for a predetermined time after the authentication. If this time is not known, the registers 234 and 236 cannot be accessed even if the authentication is obtained, so that the possibility of an unauthorized operation can be reduced.

  In the first and second embodiments, the access control device 230 is provided in the main control unit 200. However, the present invention is not limited to this, and the production control unit 300, the prize ball control unit 400, and other places It can also be provided. The same applies to the configurations of FIGS. That is, the CPUs 202, 302, and 402 that use the access control device 230 and the access control device 230 do not have to be provided on the same substrate, but can be provided on different substrates or other places.

  In the first and second embodiments, one instruction code string and an address are added to one power-on command and output. However, the present invention is not limited to this. It is also possible to add the address and the address to one power-on command for output. For example, in the connected device authentication process of FIG. 12, since the instruction code string and address are input / output four times, if four instruction code strings and addresses are added to one power-on command and output, the power-on command The connected device authentication process can be completed with a single transmission. The same applies to the configurations of FIGS.

  In the first and second embodiments, the main control unit 200 is configured to output an instruction code string and an address for each transmission of a power-on command. An instruction code string and an address may be output for each predetermined transmission unit. The same applies to the configurations of FIGS.

  As a configuration for outputting every predetermined transmission unit, for example, a configuration in which a power-on command is transmitted every n (n is an integer of 2 or more) times, and a power-on command transmitted within a predetermined time is used as a unit. It is possible to adopt a configuration in which output is performed at each start or end.

  In the first and second embodiments, the main control unit 200 is configured to add an instruction code string and an address to the power-on command. However, the present invention is not limited to this. An instruction code string and an address may be added to a plurality of types of control commands. The same applies to the configurations of FIGS.

  Other control commands include, for example, a power off command, a customer waiting demo command, a customer waiting demo stop command, a missed non-reach command, a missed reach command, a jackpot reach command, a jackpot start command, a jackpot end command, a jackpot command, symbol designation A command, a change start command, and a symbol stop command can be considered.

  In this case, a control command to which an instruction code string and an address are added can be selected in consideration of the balance between security strength and processing load. That is, if the control command has a high transmission frequency, the number of authentications per unit time increases, so the processing load increases but the security strength increases. Conversely, if the control command has a low transmission frequency, the number of authentications per unit time decreases, so the security strength decreases but the processing load decreases. Therefore, a control command with a high transmission frequency is selected in a scene where the security strength is to be increased, and a control command with a low transmission frequency is selected in a scene where the processing load is to be reduced. These scenes may be set in a table or the like as desired and held in the main control unit 200, for example. For example, it is possible to set a day or time zone in which the player is expected to exceed a predetermined number to a scene where the security strength is desired to be increased and to set a scene where the processing load is desired to be reduced on other days or time periods. .

  In the first and second embodiments, the instruction code string and the address are added after the power-on command. However, the present invention is not limited to this, and the instruction code string and the address are added before the power-on command. Alternatively, an instruction code string and an address may be added to the power-on command via other data (for example, dummy data). The power-on command and one of the instruction code string and address may be output after the predetermined time has elapsed, and the other may be output. Necessary for accessing the instruction code string and address instead of the instruction code string and address. Access information (for example, link information) may be added. The same applies to the configurations of FIGS.

  In the first and second embodiments, the access control is performed for each transmission of the power-on command. However, the present invention is not limited to this. At this timing, the access control can also be performed collectively based on the retained instruction code string and address. The same applies to the configurations of FIGS.

  In the first and second embodiments, the case where the control program stored in advance in the ROM 204 is executed in executing the game control processing shown in the flowcharts of FIGS. 10 to 15 has been described. However, the present invention is not limited to this, and the program may be read into the RAM 206 and executed from a storage medium storing the program showing these procedures. The same applies to the processing shown in the flowcharts of FIGS. 8, 16 to 18, 22 and 23.

  Here, the storage medium is a semiconductor storage medium such as RAM or ROM, a magnetic storage type storage medium such as FD or HD, an optical reading type storage medium such as CD, CDV, LD, or DVD, or a magnetic storage type such as MO. / Optical reading type storage media, including any storage media that can be read by a computer regardless of electronic, magnetic, optical, or other reading methods.

  In the first and second embodiments, the case where the present invention is applied to a pachinko machine has been described. However, the present invention is not limited to this, and a pachislot machine and an amusement game machine are within the scope of the present invention. It can be applied to other game machines.
