Description

  The present invention relates to a gaming machine such as a pachinko gaming machine, a sparrow ball gaming machine, a ball ball gaming machine such as an arrangement ball, and a revolving type gaming machine such as a slot machine installed in a gaming shop such as a pachinko shop.

Of the fraudulent acts that forcibly pay out medals, game balls, etc. (hereinafter referred to as “game media”) performed on gaming machines, regardless of the game, the main control unit that controls basic operations related to games Examples of the peripheral board on which the main control board is mounted and the peripheral board on which the peripheral unit that executes the rendering process and the like based on the control command from the main control unit are mounted include the following.
(1) Replacing an authorized main control board with an unauthorized main control board (2) A ROM storing a legitimate program executed by the CPU mounted on the main control board and an unauthorized program obtained by falsifying the above program are stored. (3) An illegal board (impersonated board) is provided between the main control board and the peripheral board, and the ROM of (2) above is replaced.

  In order to prevent such illegal acts, the conventional gaming machines include the following. For example, in the gaming machine described in Patent Document 1, the main control board generates a control command and transmits the control command to the sub-control board, and checks the control command transmitted by the first transmission means within a predetermined period. Second transmission means for transmitting the thumb as a state monitoring command at a predetermined timing. The gaming machine described in Patent Document 1 is transmitted within a predetermined period by the sub-control board comparing the checksum of the control command received within a predetermined period with the state monitoring command received at a predetermined timing. The correctness of the control command is verified. That is, the gaming machine described in Patent Document 1 attempts to prevent the illegal act by transmitting a state monitoring command for verifying the validity of the control command at a predetermined timing.

JP 2002-18095 A

  However, in the gaming machine described in Patent Document 1, a process of independently transmitting a state monitoring command at a predetermined timing is performed. Since the status monitoring command is a checksum of the control command transmitted within the predetermined period as described above, the status monitoring command and the normal control command have information of different data formats or data amounts. Therefore, in the gaming machine described in Patent Document 1, an unauthorized person can easily know the transmission timing of the state monitoring command, and can easily know the inspection timing for fraud detection. Then, there is a possibility that an unauthorized person who can know the transmission timing of the state monitoring command exploits the state monitoring command and analyzes the contents.

  In the gaming machine described in Patent Document 1, the checksum is added to the control command and transmitted. A communication error check is generally performed by adding the checksum to a control command and transmitting it. However, in the gaming machine described in Patent Document 1 in which a check sum of a control command transmitted within a predetermined period is used as a state monitoring command, an unauthorized person exploits the control command by adding the check sum to the control command. This makes it easy to analyze the contents of the status monitoring command. Specifically, as described above, an unauthorized person can easily know the transmission timing of the state monitoring command. There is a possibility that an unauthorized person who knows the transmission timing of the state monitoring command can easily analyze the contents of the state monitoring command by exploiting and comparing the control command and its checksum within a predetermined period. .

  Moreover, in the gaming machine described in Patent Document 1, a process different from the normal process of transmitting a state monitoring command is performed. As a result, the processing becomes complicated, and it is necessary to store all the checksums transmitted within a predetermined period, which increases the processing load on the main control board. In gaming machines, the ROM and RAM capacities of the main control board are limited due to the regulations of the “Customs Business Regulations and the Act on the Optimization of Business (Fusei Law)”, and the resources of the main control board are limited. . Nevertheless, there was a request from a gaming machine manufacturer to allocate a large amount of limited capacity to programs related to the production of gaming machines. For this reason, an increase in processing load on the main control board due to processing related to security is a serious problem that cannot be overlooked.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a gaming machine capable of improving the security strength by preventing the above fraudulent acts by simple means that have not been conventionally used.

In order to solve the above-described problems, the present invention is a gaming machine including a main control unit (main control unit 10) that outputs a control command and a peripheral unit (peripheral unit 30) that performs processing based on the control command. The main control unit checks the validity of the control command using at least the output command for outputting the control command (control command output unit 500) and the control command output by the output unit in the past in the past. First generation means (error check value generation unit 510) for generating and outputting an error check value, and adding the error check value output by the first generation means to the control command output by the output means. Transmission means (addition unit 540 and transmission unit 550) for transmitting to the peripheral part, wherein the peripheral part generates an error check value of the control command transmitted in the predetermined past Inspection means for inspecting the validity of the transmitted control command using the stage (error inspection value generation unit 610), the transmitted error inspection value and the error inspection value generated by the second generation means (Error checking unit 640).

  According to the present invention, the error check value generated by the generation unit using at least the control command output in the past by the output unit is added to the control command output this time and transmitted to the effect control unit. In this way, by applying an unprecedented simple method, it becomes difficult for an unauthorized person to analyze the relationship between a control command and an error check value added to the control command. Even if the value is exploited, it can be difficult to cheat. That is, according to the present invention, the security strength of the gaming machine can be improved by a simple method.

  The error check value storage unit 530 includes, among the error check values generated by the error check value generation unit 520, an error check value generated using the control command transmitted this time and an error check value generated using the control command transmitted last time. At least two of them. Further, the error check value storage unit 530 sends the error check value generated using the previously transmitted control command to the adding unit 540. Specific means for realizing the function of the inspection value storage unit 530 can be configured by the generation transmission circuit 10g shown in FIG.

  The adding unit 540 adds the error check value generated by using the control command transmitted from the error check value storage unit 530 to the control command to be transmitted this time output from the control command output unit 500, Control command information to be transmitted to the effect control unit 203 is generated. Specific means for realizing the function of the adding unit 540 can be configured from the generation / transmission circuit 10g shown in FIG.

  Here, the control command information is a generic name of control signals transmitted from the main control unit 10 to the effect control unit 203, and includes a control command (control command data) and an error check value added thereto. Hereinafter, the control command with an error check value is also referred to as control command information. FIG. 4 shows the format of the control command information in this embodiment. As shown in FIG. 4, the control command information basically has a format in which an error check value of the control command transmitted immediately before is added to the control command. However, a predetermined initial value is added to the control command 1 transmitted first. The initial value is not particularly limited, and dummy data of a predetermined error check value, an ID unique to the gaming machine such as an ID unique to the main control board, or the like can be used. Then, the error check value 1 of the control command 1 transmitted first is added to the control command 2 transmitted second, and control command information is generated. Similarly, the error check value 2 of the control command 2 transmitted second is added to the control command 3 transmitted third, and control command information is generated. Thereafter, control command information is generated in the same manner.

  The transmission unit 550 transmits the control command information generated by adding the error check value of the control command transmitted last time to the control command transmitted this time to the effect control unit 203. Specific means for realizing the function of the transmission unit 550 can be configured from the generation transmission circuit 10g shown in FIG.

Next, processing of each component of the main control unit 10 during authentication processing will be described. FIG. 5 is a sequence diagram showing processing relating to authentication of the main control unit.
After the pachinko gaming machine 1 is turned on and the CPU 10a of the main control unit 10 performs an initial setting process, the control command output unit 10 constituting the main control unit 10 starts outputting the control command. As described above, a predetermined initial value is added to the control command transmitted first, instead of the error check value.

In step S31, the control command output unit 500 generates a control command to be transmitted this time to the effect control unit 203, and outputs the control command to the error check value generation unit 510 and the addition unit 540.
In step S32, the error check value generation unit 510 that has received the control command output from the control command output unit 500 generates an error check value using the received control command transmitted this time. Subsequently, in step S33, the error check value generation unit 510 stores the generated error check value. Subsequently, in step S <b> 34, error check value generation unit 510 outputs the error check value of the previously transmitted control command stored in advance to addition unit 540.

  Next, in step S35, the adding unit 540 adds the previously transmitted control command output from the error check value generating unit 510 in step S34 to the control command transmitted this time output from the control command output unit 500 in step S31. Control command information is generated by adding the error check value generated using the error check value and sent to the transmission unit 550. Subsequently, in step S <b> 36, the transmission unit 550 transmits the control command information received from the adding unit 540 to the effect control unit 203.

  In this embodiment, the error check value generation unit 510 generates an error check value of the control command to be transmitted this time (step S32), stores the generated error check value (step S33), and then transmits the control transmitted last time. Although the command error check value is output to the adding unit 540 (step S34), the present invention is not limited to this. For example, after the error check value generation unit 510 outputs the error check value of the control command transmitted last time to the adding unit 540 (step S34), the error check value generation unit 510 generates the error check value of the control command to be transmitted this time (step S32) and generates The error check value may be stored (step S33).

Next, the types of control commands transmitted from the main control unit 10 to the effect control unit 203 will be described with reference to FIG. FIG. 6 is a diagram showing an example of the types of control commands output by the main control unit 10 constituting the pachinko gaming machine 1 according to the embodiment of the present invention, and the control commands shown in FIG. It is not limited to the type.

This power-on command is transmitted to the effect control unit 203 when the pachinko gaming machine 1 is powered on. Specifically, when the power of the pachinko gaming machine 1 is turned on, the control command output unit 500 constituting the main control unit 10 outputs a power-on command to the error check value generation unit 510 and the addition unit 540. Since this power-on command is the control command that is output first, the adding unit 540 adds the initial value stored in advance to the power-on command instead of the error check value generated from the control command, and provides control command information. The transmission unit 550 transmits this control command information.

The “customer waiting demonstration command” indicates that the pachinko machine 1 displays a demonstration screen waiting for a customer in a non-game state, “MODE” is set to “E2H”, and “DATA” is “00H”. Is set to
This customer waiting demo command is an effect control unit when a predetermined time elapses after the demonstration is started as an initial presentation display displayed when the power is turned on, or after the number of undrawn winning prizes described later becomes zero and the demonstration starts. 203.

The “symbol change pattern command” indicates that the game ball wins at the start port (first start port 105 or second start port 125) of the pachinko gaming machine 1 and the symbol change according to the winning lottery result on the symbol display unit 104. In this example, “MODE” is set as “E3H”, and DATA information is set according to various variation patterns.
The symbol variation pattern command is transmitted to the effect control unit 203 when various symbol variation patterns are determined after the jackpot determination at the time of winning lottery. Specifically, it is determined whether the jackpot determination random number acquired at the time of winning lottery corresponds to any random number value in the preset jackpot determination table, various symbol variation patterns are determined, and symbol variation is started. The symbol variation pattern command corresponding to the determined symbol variation pattern is transmitted to the effect control unit 203.

The “symbol stop command” indicates that the symbol variation is stopped and displayed, “MODE” is set to “E4H”, and “DATA” is set to “00H”.
The symbol stop command is transmitted to the effect control unit 203 after the symbol variation has started and the symbol variation time has elapsed. Specifically, since the symbol variation time set in advance has elapsed after the symbol variation has started, the symbol variation is transmitted to the effect control unit 203 when the symbol variation is stopped.

The “big jack start command” indicates that various jackpots start, “MODE” is set as “E5H”, and DATA information is set according to the jackpot type.
In the jackpot start command, when various jackpots start, a jackpot start command corresponding to the jackpot type is transmitted to the effect control unit 203. Specifically, at the start of the jackpot game process, a jackpot start command corresponding to the jackpot type is transmitted to the effect control unit 203.

The “big hit command” indicates the number of big hit rounds according to various types of big hits, “MODE” is set as “E6H”, and DATA information is set according to the number of round hits.
As for the jackpot command, when the jackpot round is started, the jackpot command corresponding to the started round number is transmitted to the effect control unit 203. Specifically, when opening the first big prize opening / closing door 109a or the second big prize opening / closing door 129a, a big hit command corresponding to the number of rounds to be opened is transmitted to the effect control unit 203.

The “big jackpot end command” indicates that various jackpots have ended, “MODE” is set as “E7H”, and DATA information is set according to the jackpot type.
The jackpot end command is transmitted to the effect control unit 203 when a variety of jackpots end, corresponding to the jackpot type. Specifically, at the start of the jackpot game end process, a jackpot end command corresponding to the jackpot type is immediately transmitted to the effect control unit 203.

  FIG. 7 is a functional block diagram showing a configuration related to the authentication process of the effect control unit 203 constituting the pachinko gaming machine 1 according to the embodiment of the present invention. The effect control unit 203 includes a receiving unit 600, an error check value generation unit 610, and an error check unit 640. Further, the error check value generation unit 610 includes an error check value calculation unit 620 and an error check value storage unit 630. Each functional block constituting the effect control unit 203 is configured by appropriately combining the respective means such as the CPU 203a, the ROM 203b, and the RAM 203c shown in FIG.

  The reception unit 600 has a reception data storage area, and writes the control command information received from the main control unit 10 in the reception data storage area. The receiving unit 600 transmits the control command received this time included in the received control command information to the error check value generation unit 610 and the error check value added to the control command received this time to the error check unit 640. . Specific means for realizing the function of the receiving unit 600 can be configured from a part of the CPU 203a, a part of the ROM 203b, a part of the RAM 203c, and the like shown in FIG. More specifically, the CPU 203a uses the RAM 203c as a work area, based on a program stored in advance in the ROM 203b, the control command extracted from the control command information received this time to the error check value generation unit 610, and the error check value. Transmit to the error checking unit 640.

  The error check value generation unit 610 generates an error check value using the control command received from the reception unit 600 this time. Further, the error check value generation unit 610 sends the control command sent from the receiving unit 600 last time, that is, the error check value generated using the control command received last time by the effect control unit 203 to the error checking unit 640.

  Specifically, the error check value calculation unit 620 constituting the error check value generation unit 610 generates an error check value using the control command sent from the receiving unit 600 and received this time by the effect control unit 203, The generated error check value is sent to the error check value storage unit 630 constituting the error check value generation unit 610. Specific means for realizing the function of the inspection value calculation unit 620 can be configured from a part of the CPU 203a, a part of the ROM 203b, a part of the RAM 203c, and the like shown in FIG. In the present embodiment, the error check value generation method may be the same as the error check value generation method performed by the error check value generation unit 510 of the main control unit 10, and the error check value generation performed by the generation transmission circuit 10g. Like the method, there is no particular limitation, and the various methods described above can be applied.

  The error check value storage unit 630 includes, among the error check values generated by the error check value generation unit 620, an error check value generated using the control command received this time and an error generated using the control command received last time. Store at least two of the test values. In addition, the error check value storage unit 630 sends the error check value generated using the previously received control command to the error check unit 640. Specific means for realizing the function of the inspection value storage unit 530 can be configured by the CPU 203a, the ROM 203b, and the RAM 203c shown in FIG.

  The error check unit 640 generates an error check using the error check value added to the control command received this time sent from the receiving unit 600 and the control command received from the error check value storage unit 630 last time. Perform error checking using values. That is, the error checking unit 640 performs an authentication process for authenticating the validity of the control command to which the currently received error check value is added and the previously received control command from which the current error check value is generated. Specific means for realizing the function of the error checking unit 640 can be constituted by the CPU 203a, the ROM 203b, and the RAM 203c shown in FIG.

Next, processing of each component of the effect control unit 203 in the authentication process will be described. FIG. 8 is a sequence diagram illustrating processing related to authentication of the effect control unit 203.
After the pachinko gaming machine 1 is turned on and the CPU 10a of the main control unit 10 performs the initial setting process, the control command output unit 500 constituting the main control unit 10 starts outputting the control command, and the effect control unit Control command information which is a control command with an error check value is transmitted to 203. As described above, a predetermined initial value is added to the control command transmitted first, instead of the error check value.

  In step S41, the receiving unit 600 receives control command information that is a control command with an error check value, and writes it in the received data storage area. Subsequently, in step S42, the receiving unit 600 outputs the control command of the received control command with error check value to the error check value generation unit 610 and the error check value to the error check unit 640.

  In step S43, the error check value generation unit 610 that has received the control command received this time from the reception unit 600 generates an error check value using the control command received this time. Subsequently, in step S44, the error check value generation unit 610 stores the generated error check value. Subsequently, in step S <b> 45, error check value generation section 610 outputs the error check value of the previously received control command stored in advance to error check section 640.

  Next, in step S46, the error checking unit 640 outputs the error check value added to the control command received this time output from the receiving unit 600 in step S42 and the error check value generating unit 610 in step S45. An error check is performed using the error check value generated using the control command received last time. Specifically, the error checking unit 640 compares the above two error check values to verify whether they are the same value. If they are the same, the error checking unit 640 authenticates the validity of the control command received this time and the previous time. If they are not the same, the error checking unit 640 determines that the control command is not valid and has an error. Since a predetermined initial value is added to the control command received first instead of the error check value, the error checker 640 similarly performs error check using the predetermined initial value.

  In this embodiment, the error check value generation unit 610 generates the error check value of the control command received this time (step S43), stores the generated error check value (step S44), and then receives the control received last time. The command error check value is output to the error check unit 640 (step S45), but the present invention is not limited to this. For example, after the error check value generation unit 610 outputs the error check value of the control command received last time to the error check unit 640 (step S45), the error check value generation unit 610 generates the error check value of the control command received this time (step S43), The generated error check value may be stored (step S44).

[Game machine operation processing]
Next, the operation process of the pachinko gaming machine 1 configured as described above will be described with reference to the drawings. Hereinafter, an operation process including transmission of a control command to the effect control unit 203 by the main control unit 10 will be described with reference to a flowchart shown in FIG. The CPU 10a, which is a component of the main control unit 10, performs processing such as execution of a control command every predetermined cycle (for example, 4 milliseconds) based on a clock signal output from a pulse generation unit (not shown). In the following description, the transmission process of each control command includes a process of generating control command information by adding an error check value (or initial value) to the control command and transmitting the generated control command information. Details of this control command transmission processing will be described later.

  In step S1, the main control unit 10 first executes an initial setting process associated with power-on of the pachinko gaming machine 1, and then proceeds to step S2. When power is supplied to the pachinko gaming machine 1, the peripheral board starts up and initializes the RAM area to ensure that the peripheral board receives the control command received from the main control board. After that, the main control board is configured to stand up. As an initial setting process, the main control unit 10 sets a predetermined value for the stack pointer, for example, and waits for the effect control unit 203 to enter a standby state (for example, about 1 second). ) Just wait.

  In step S2, the control command output unit 500 outputs the power-on command shown in FIG. 5 to the effect control unit 203 to the adding unit 540, and the power-on command (see FIG. 4) with the initial value added by the adding unit 540. Transmission unit 550 transmits to effect control unit 203. After transmitting the power-on command, the main control unit 10 proceeds to step S3. When the power-on command is received, the effect control unit 203 controls the design display command at the time of power-on to each of the symbol display unit 104 and the lamp control unit 205, specifically, the customer in the non-game state of the gaming machine. A customer waiting demo command for displaying a waiting demo screen or a control command for lighting a lamp or the like is transmitted.

  The power-on command indicates a control command for executing processing associated with power-on after power-on, and is a control command transmitted from the main control unit 10 to the effect control unit 203 after each control board is started up. Initial control information for controlling the game at the start-up after power-on, for example, control commands for transmitting the control mode, backup data, etc., or control commands for controlling the initial effect display, This is a control command for starting the demonstration display. The power-on command also includes a control command for transmitting the control mode, backup data, etc., which is also executed when the reset button of the gaming machine is pressed.

  In step S <b> 3, the main control unit 10 determines whether or not the number of undrawn winning prizes is 0 with reference to the data for undrawn winning prizes stored in the RAM 10 c. Here, the number of undrawn winning prizes refers to a lottery corresponding to the number of winning game balls based on the number of game balls (number of winning prizes) detected by the first start port detecting unit 221 or the second start port detecting unit 225. This is the number obtained by subtracting the number of times performed (number of already drawn lots). If the determination result in step S3 is “NO”, that is, if the number of undrawn winning prizes is not zero, the main control unit 10 proceeds to step S10 described later. On the other hand, when the determination result of step S3 is “YES”, that is, when the number of undrawn winning prizes is 0, the main control unit 10 proceeds to step S4.

In step S4, the main control unit 10 measures the time that has elapsed since the start-up demonstration was started, and then proceeds to step S5.
In step S <b> 5, the main control unit 10 determines whether or not a predetermined time has elapsed since the start-up demonstration was started. If the determination result in step S5 is “YES”, that is, if a predetermined time has elapsed since the demonstration at power-on was started, the main control unit 10 proceeds to step S6. Note that the control command for starting the demonstration when the power is turned on may be a customer waiting demonstration command.

  In step S6, the main control unit 10 transmits a customer waiting demonstration command to the effect control unit 203, and then proceeds to step S7. When the customer waiting demonstration command is received, the effect control unit 203 transmits a control command for customer waiting demonstration effect to each of the symbol display unit 104 and the lamp control unit 205.

On the other hand, if the determination result in step S5 is “NO”, that is, if a predetermined time has not elapsed since the start of the power-on demonstration (or the customer waiting demo), the main control unit 10 Proceed to S7.
In step S <b> 7, the main control unit 10 determines whether the first start port detection unit 221 detects the entry of a game ball into the first start port 105 or the second start port detection unit 225 detects the entry to the second start port 120. It is determined whether or not a game ball is detected. If the determination result in step S7 is “YES”, that is, whether the first start port detection unit 221 detects that a game ball has entered the first start port 105 or the second start port detection unit 225 performs the second start. When a game ball entering the mouth 120 is detected, the main control unit 10 proceeds to step S8.

  On the other hand, if the determination result in step S7 is “NO”, that is, the first start port detector 221 does not detect the entry of a game ball into the first start port 105, and the second start port detector 225 In the case where the entry of the game ball into the second starting port 120 is not detected, the main control unit 10 returns to step S4 and repeats the processing after step S4.

In step S8, the main control unit 10 clears the time that has been measured since the start of the customer waiting demo (or demo at power-on), and then proceeds to step S9.
In step S9, the main control unit 10 adds 1 to the number of undrawn winning prizes. If the first start port detection unit 221 or the second start port detection unit 225 detects a plurality of game balls entering, the main control unit 10 enters the number of undrawn winnings in this step S9. Add the corresponding numbers. Then, the main control unit 10 proceeds to step S10.

In step S10, the main control unit 10 randomly acquires one jackpot determination random number from a random number counter (for example, counts 0 to 255) prepared in advance, and then proceeds to step S11.
In step S11, the main control unit 10 subtracts 1 from the number of undrawn winning prizes, and then proceeds to step S12.

  In step S12, the main control unit 10 refers to the jackpot determination data table stored in advance in the data storage unit 510, for example, and the jackpot determination random number acquired in the process of step S10 is stored in the jackpot determination data table. It is determined whether or not the jackpot random number value is stored. In step S12, the main control unit 10 refers to the jackpot determination data table, for example, when the acquired big hit determination random number is an out-of-range random number, and further “reach with reach” or “without reach”. It is also judged whether it is “out of”. If the determination result in step S12 is “YES”, that is, if the jackpot determination random number acquired in step S10 is a predetermined jackpot random number, the main control unit 10 proceeds to step S13.

In step S13, the main control unit 10 determines, for example, a symbol variation command (a jackpot reach command) including “MODE” information such as a jackpot type code (whether it is a normal hit or a probability variation), reach, symbol variation time, etc. ) Is set in the transmission unit 520 and transmitted to the effect control unit 203, the process proceeds to step S14.
In step S14, the main control unit 10 determines whether or not the symbol variation time has elapsed. If the determination result in step S14 is “NO”, that is, if the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S14 is “YES”, and the main control unit 10 proceeds to step S15.

In step S15, the main control unit 10 transmits a symbol stop command to the effect control unit 203, and then proceeds to step S16.
In step S16, the main control unit 10 transmits a jackpot start command to the effect control unit 203, and then proceeds to step S17.
In step S <b> 17, the main control unit 10 sequentially transmits commands corresponding to each round of jackpot (hit command) to the effect control unit 203, and after completing the transmission of the jackpot command for all rounds, proceeds to step S <b> 18. .
In step S18, the main control unit 10 transmits a jackpot end command to the effect control unit 203, and then proceeds to step S22.

On the other hand, if the determination result in step S12 is “NO”, that is, if the jackpot determination random number obtained in the process of step S10 is not a predetermined jackpot random number, the main control unit 10 proceeds to step S19.
In step S19, the main control unit 10 gives a symbol variation pattern command (out of reach reach command) corresponding to “out of reach” in the case of “out of reach” and in the case of “out of reach”. After transmitting the symbol fluctuation pattern command (outgoing command) corresponding to “out of reach” to the effect control unit 203, the process proceeds to step S20.

In step S20, the main control unit 10 determines whether or not the symbol variation time has elapsed. When the determination result of step S20 is “NO”, that is, when the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S20 is “YES”, and the main control unit 10 proceeds to step S21.
In step S21, the main control unit 10 transmits a symbol stop command to the effect control unit 203 to the effect control unit 203, and then proceeds to step S22.

  In step S22, the main control unit 10 determines whether or not the power of the pachinko gaming machine 1 has been turned off. When the determination result of step S22 is “NO”, that is, when the power of the pachinko gaming machine 1 is not turned off, the main control unit 10 returns to step S3 and repeats the processes after step S3.

On the other hand, when the determination result of step S22 is “YES”, that is, when the power of the pachinko gaming machine 1 is turned off, the main control unit 10 proceeds to step S23.
In step S <b> 23, the main control unit 10 transmits an end process command to the effect control unit 203 to the effect control unit 203, and then ends the process according to this flowchart.

Hereinafter, the customer waiting demonstration command in step S6, the symbol variation pattern command in steps S13 and S19, the symbol stop command in steps S15 and S21, the jackpot start command in step S16, the jackpot command in step S17, and step S18 shown in FIG. The procedure of each control command transmission process of the jackpot end command will be described.
FIG. 10 is a flowchart illustrating an example of a procedure of control command transmission processing by the main control unit 10.

  When it is the transmission timing of the control command in the main process of the main control unit 10 shown in FIG. 9, in step S51, the error check value generation unit 510 outputs the error of the control command to be transmitted this time output from the control command output unit 500. An inspection value is generated, and the process proceeds to step S52.

  In step S52, the error check value generation unit 510 stores the generated error check value, and proceeds to step S53. In this embodiment, the error check value generation unit 510 may store two error check values, that is, the error check value of the control command transmitted last time and the error check value of the control command transmitted this time.

In step S53, the adding unit 540 receives the error check value of the previously transmitted control command stored in the error check value generating unit 510, adds it to the control command to be transmitted this time, and generates control command information. Proceed to S54.
In step S54, the transmission unit 550 receives the control command information generated by the adding unit 540 and transmits the control command information to the effect control unit 203, and then ends the process according to the flowchart.

  In this embodiment, step S51 for generating a check value for the control command to be transmitted this time is performed, step S52 for storing the generated error check value is performed, and then step S53 for generating control command information is performed. Although step S54 for transmitting control command information is performed, the present invention is not limited to this. For example, after performing steps S53 and S54, steps S51 and S52 for generating and storing error check values may be performed, and steps S51 and S52 for generating and storing error check values after performing step S53. You may go. In this case, the error check value generation unit 510 only needs to store at least one error check value, and in step S52 for storing the error check value, the error check value already stored is overwritten with the new error check value. You may make it preserve | save.

Hereinafter, the control processing executed by the effect control unit 203 will be described with reference to the flowcharts shown in FIGS.
FIG. 11 is a flowchart illustrating an example of the procedure of the main process performed by the effect control unit 203.
In step S1000, the CPU 203a of the effect control unit 203 performs an initial setting process. In this process, the CPU 203a reads a program code related to the main process from the ROM 203b of the effect control unit 203 in response to power-on. At the same time, the CPU 203a performs a process of initializing a flag stored in the RAM 203c of the effect control unit 203 and setting it to a predetermined value. If this process ends, the process moves to a step S1100.

Details of the authentication processing will be described later with reference to FIG. When the authentication process is completed, the process proceeds to step S1420.

In step S1420, when the control command written in the reception data storage area is the customer waiting demo command (see step S6 in FIG. 9), the effect control unit 203 proceeds to step S1421 and is not a customer waiting demo command. If YES, go to step S1430.
In step S1421, the effect control unit 203 performs a demonstration effect process for determining an effect pattern for a customer waiting demonstration. More specifically, an effect pattern for the customer waiting demonstration is determined, and an effect processing command based on the determined demonstration effect pattern is written in the transmission data storage area of the RAM 203c as transmission data, and the symbol display unit 140 and the lamp control unit 205 are used.

The process proceeds to S1431, and if it is not the symbol variation pattern command, the process proceeds to Step S1440.
In step S1431, the effect control unit 203 performs symbol variation effect processing for determining one variation effect pattern from the various variation effect patterns prepared for each of the jackpot or loss. Specifically, the effect control unit 203 acquires one random number value from the effect random number value updated in step S1100 in FIG. 11, and determines the effect effect random number that is stored in advance in the acquired effect random number value and the ROM 203b. One variation effect pattern is determined based on the table. Then, the effect control unit 203 writes an effect processing command based on the determined variation effect pattern in the transmission data storage area to be transmitted data, which is transmitted to the symbol display unit 140 and the lamp control unit 205.

In step S1440, when the control command written in the received data storage area is the symbol stop command (see step S15 or step S21 in FIG. 9), the effect control unit 203 proceeds to step S1441 and proceeds to symbol stop command. If not, the process proceeds to step S1450.
In step S1441, the effect control unit 203 performs a symbol stop effect process for stopping and displaying the effect symbol indicating the variation mode. Specifically, the effect control unit 203 writes an effect processing command based on the symbol stop command in the transmission data storage area to be transmitted data, and transmits the transmission data to the symbol display unit 140 and the lamp control unit 205.

In step S1450, the effect control unit 203 proceeds to step S1451 if the control command written in the received data storage area is a jackpot start command (see step S16 in FIG. 9), and if it is not a jackpot start command, The process proceeds to step S1460.
In step S1451, the effect control unit 203 performs a jackpot start effect process for determining a jackpot start effect pattern.

  Hereinafter, the authentication process performed by the effect control unit 203 in step S1410 shown in FIG. 13 will be described with reference to the flowchart shown in FIG. FIG. 14 is a flowchart illustrating an example of the authentication processing procedure performed by the effect control unit 203.

  When the processing timing of the authentication process is reached in the command analysis process of the effect control unit 203 shown in FIG. 13, in step S1411, the receiving unit 600 of the effect control unit 203 acquires an error check value from the control command information received this time. . In addition, receiving section 600 outputs the control command received this time to error check value generation section 610 and the acquired error check value to error check section 640, and proceeds to step S1412.

  In step S1412, the error check value generation unit 610 of the effect control unit 203 acquires the control command received this time from the reception unit 600, and generates and generates an error check value using the acquired control command received this time. The error check value is saved and the process proceeds to step S1413.

  In step S1413, the error checking unit 640 of the effect control unit 203 collates the error check value acquired in step S1411 with the error check value generated by using the control command previously received by the error check value generating unit 610, and the error is detected. Perform an inspection. If they are the same, the error checking unit 640 authenticates the validity of the control command received this time and the previous time (the result of step S1414 is YES), and ends the processing according to this flowchart. If they are not identical, the error checking unit 640 determines that the control command is not valid and has an error (the result of step S1414 is NO), proceeds to step S1415, performs error detection notification, and this flowchart. The process by is terminated.

  In step S1415, the effect control unit 203 determines that there is a possibility that an illegal act or a communication error has occurred, and outputs a notification signal to notify that effect. The effect control unit 203 transmits the generated notification signal to, for example, the symbol display unit 104, the lamp control unit 205, or a center control device that manages the pachinko gaming machine 1. Based on the received notification signal, the symbol display unit 104, the lamp control unit 205, and the like execute an effect of notifying that there is a possibility that an illegal act or a communication error has occurred in the pachinko gaming machine 1. This effect is, for example, causing a character that does not normally appear in the symbol display unit 104 to appear, or causing a character that normally appears to appear in a manner different from the normal. Further, the brightness of the symbol display unit 104 may be changed, the color may be changed, or the lamp control unit 205 may be controlled to display a predetermined lamp. In any case, when the employee of the game shop passes in front of the pachinko gaming machine 1, it is only necessary to be aware of the state. This effect may be an effect that the customer does not notice the state or an effect that the customer can easily notice. If the production is easily noticed by the customer, fraud can be efficiently suppressed.

  Further, the notification signal may include information on the gaming state of the pachinko gaming machine 1 such as “Big hit” and “Probability changing”. Based on the information on the gaming state, it may be determined whether or not an illegal act is performed by a center control device that manages the pachinko gaming machine 1 or the like. For example, there may be a case where winnings are concentrated during jackpots or probability fluctuations even if the winnings are concentrated. Therefore, it is better to determine whether or not there is a risk of fraudulent behavior under conditions different from other states during jackpots or probability fluctuations. Moreover, you may make it output the information regarding a gaming state as another signal, without including in a notification signal. In this case, the employee determines whether there is a risk of fraud based on both the notification signal and the information regarding the gaming state.

  Note that the authentication process between the main control unit 10 and the prize ball control unit 204 is performed in substantially the same procedure as the authentication process between the main control unit 10 and the effect control unit 203, and thus description thereof is omitted. To do.

As described above, in the present embodiment, the main control unit 10 generates and stores an error check value for the control command. And the main control part 10 adds the error check value of the control command transmitted last time to the control command transmitted this time, and transmits to the effect control part 203 as control command information. On the other hand, the effect control unit 203 generates and stores an error check value for the received control command. Then, the effect control unit 203 performs an error check by comparing the error check value included in the control command information received this time with the error check value of the control command received last time.
That is, the gaming machine according to the present invention adds the error check value of the control command transmitted in the past to the control command transmitted this time, and transmits it from the main control unit 10 to the effect control unit 203.

  An error check value such as a normal checksum is added to the control command of the generation source and used for communication error check. On the other hand, the gaming machine 1 of the present embodiment adds the error check value of the control command transmitted last time to the control command transmitted this time as described above. By using such an unprecedented new and simple technique, even if an unauthorized person illegally exploits a control command and an error check value, the relationship between the control command and the error check value cannot be easily known. Therefore, according to this embodiment, fraud by an unauthorized person can be prevented and the security strength can be improved.

  In addition, the error check value of the control command transmitted last time by the main control unit 10 is transmitted in addition to the control command transmitted this time, and the effect control unit 203 performs authentication processing, whereby the validity of the control command received this time is verified. And the validity of the control command received last time, that is, the control command from which the error check value added this time is generated can be authenticated. That is, the continuity of the control command can be authenticated.

  Further, in this embodiment, an error check value is added to each control command and transmitted from the main control unit 10 to the production control unit 203, and the production control unit 203 performs an authentication process for each control command. Can be inspected.

  In addition, the gaming machine 1 of the present embodiment normally uses an error check value used for communication error check as a check value for detecting fraud. In this way, by using the error check value conventionally used for the communication error check, it is possible to prevent fraud by an unauthorized person with a simple configuration without providing a means for separately generating a check value for performing the error check value. Can be prevented, and the security strength can be improved. That is, in a situation where the resources of the main control board of the gaming machine are limited, it is possible to suppress an increase in processing load on the main control board while improving the security strength.

Further, the error check value calculation unit 830 sends the error check value generated using the previously transmitted control command to the adding unit 540. Specific means for realizing the function of the inspection value calculation unit 830 can be configured by the generation transmission circuit 10g shown in FIG.

Next, processing of each component of the main control unit 10 during authentication processing will be described. FIG. 17 is a sequence diagram showing processing relating to authentication of the main control unit.
After the pachinko gaming machine 1 is turned on and the CPU 10a of the main control unit 10 performs an initial setting process, the control command output unit 10 constituting the main control unit 10 starts outputting the control command.

In step S <b> 61, the control command output unit 500 generates a control command to be transmitted this time to the effect control unit 203 and outputs the control command to the error check value generation unit 810 and the addition unit 540.
The error check value generation unit 810 that has received the control command output from the control command output unit 500 stores the received control command to be transmitted this time in the control command storage unit 820 in step S62. Subsequently, in step S63, the error check value calculation unit 830 receives the previously transmitted control command already stored in the control command storage unit 820, and generates an error check value using the previously transmitted control command. . In step S64, the error check value of the previously transmitted control command generated in step S63 is output to the adding unit 540.

  FIG. 18 is a functional block diagram showing a configuration related to authentication processing of the effect control unit 203 constituting the pachinko gaming machine according to the second embodiment of the present invention. The effect control unit 203 includes a receiving unit 600, an error check value generation unit 910, and an error check unit 640. Further, the error check value generation unit 910 includes a control command storage unit 920 and an error check value calculation unit 930. Each functional block constituting the effect control unit 203 is configured by appropriately combining the respective means such as the CPU 203a, the ROM 203b, and the RAM 203c shown in FIG.

  The reception unit 600 has a reception data storage area, and writes the control command information received from the main control unit 10 in the reception data storage area. The receiving unit 600 transmits the control command received this time included in the received control command information to the error check value generation unit 910 and the error check value added to the control command received this time to the error check unit 640. . The error checking unit 640 uses the error check value added to the control command received this time sent from the receiving unit 600 and the error check value generated using the control command received from the error check value generating unit 910 last time. Perform error checking using values.

  The error check value generation unit 910 stores the control command received from the reception unit 600 this time. Further, the error check value generation unit 910 sends the control command sent from the receiving unit 600 last time, that is, the error check value generated using the control command received last time by the effect control unit 203 to the error checking unit 640.

  Specifically, the control command storage unit 920 constituting the error check value generation unit 910 stores the control command output from the reception unit 600. In the present embodiment, it is only necessary to store at least two of the control command received this time and the control command received last time. Further, the control command storage unit 920 stores the control command received this time and outputs the control command received last time to the error check value calculation unit 930. Specific means for realizing the function of the control command storage unit 920 can be configured from a part of the CPU 203a, a part of the ROM 203b, a part of the RAM 203c, and the like shown in FIG.

  The error check value calculation unit 930 generates an error check value using the previously received control command output from the control command storage unit 920. Further, the error check value calculation unit 930 sends the error check value generated using the previously received control command to the error check unit 640. Specific means for realizing the function of the error check value calculation unit 930 can be configured from a part of the CPU 203a, a part of the ROM 203b, a part of the RAM 203c, and the like shown in FIG.

Next, processing of each component of the effect control unit 203 during the authentication process will be described. FIG. 19 is a sequence diagram showing processing related to authentication of the effect control unit 203.
After the pachinko gaming machine 1 is turned on and the CPU 10a of the main control unit 10 performs the initial setting process, the control command output unit 500 constituting the main control unit 10 starts outputting the control command, and the effect control unit Control command information which is a control command with an error check value is transmitted to 203. As described above, a predetermined initial value is added to the control command transmitted first, instead of the error check value.

  In step S71, the receiving unit 600 receives control command information that is a control command with an error check value, and writes it in the received data storage area. Subsequently, in step S <b> 72, the receiving unit 600 outputs the control command of the received control command with error check value to the error check value generation unit 910 and the error check value to the error check unit 640.

  The error check value generation unit 910 that has received the control command received this time from the receiving unit 600 stores the control command received this time in step S73. Subsequently, in step S74, the error check value generation unit 910 acquires a previously received control command that has already been stored, and generates an error check value using the previously received control command. Subsequently, in step S <b> 75, the generated error check value of the previously received control command is output to the error check unit 640.

  Next, in step S76, the error checker 640 sends the error check value added to the control command received this time output from the receiver 600 in step S42 and the error check value generator 910 sent in step S75. An error check is performed using the error check value generated using the control command received last time. Specifically, the error checking unit 640 compares the above two error check values to verify whether they are the same value. If they are the same, the error checking unit 640 authenticates the validity of the control command received this time and the previous time. If they are not the same, the error checking unit 640 determines that the control command is not valid and has an error. Since a predetermined initial value is added to the control command received first instead of the error check value, the error checker 640 similarly performs error check using the predetermined initial value.

  In the present embodiment, the error check value generation unit 910 saves the control command received this time (step S73), then generates an error check value of the control command received last time (step S74), and generates the generated error. Although the inspection value is output to the error inspection unit 640 (step S75), the present invention is not limited to this. For example, the error check value generation unit 910 generates the error check value of the control command received last time (step S74), outputs the generated error check value to the error check unit 640 (step S75), and then receives the control received this time. The command may be saved (step S73).

When the control command transmission timing comes in the main process of the main control unit 10 shown in FIG. 9, the error check value generation unit 810 stores the control command to be transmitted this time output from the control command output unit 500 in step S81. Then, the process proceeds to step S82.
In step S82, the error check value generation unit 810 receives the previously transmitted control command transmitted previously, generates an error check value using the previously transmitted control command, and proceeds to step S83.

In step S83, the adding unit 540 receives the error check value of the previously transmitted control command from the error check value generating unit 810, and adds this error check value to the control command to be transmitted this time output from the control command output unit 500. Then, control command information is generated, and the process proceeds to step S84.
In step S84, the transmission unit 550 receives control command information, which is a control command with an error check value, from the adding unit 540, transmits the control command information to the effect control unit 203, and ends the processing according to this flowchart.

  In the present embodiment, the timing of step S81 for storing the control command to be transmitted this time is not limited to the above timing, and step S81 may be performed after step S84 for transmitting control command information.

FIG. 21 is a flowchart illustrating an example of the authentication processing procedure performed by the effect control unit 203.

  Hereinafter, the authentication process performed by the effect control unit 203 in step S1410 shown in FIG. 13 will be described with reference to the flowchart shown in FIG. FIG. 21 is a flowchart illustrating an example of the authentication processing procedure performed by the effect control unit 203.

  When the processing timing of the authentication process is reached in the command analysis process of the effect control unit 203 shown in FIG. 13, in step S91, the receiving unit 600 of the effect control unit 203 acquires an error check value from the control command information received this time. . In addition, receiving section 600 outputs the control command received this time to error check value generation section 910 and the acquired error check value to error check section 640, and proceeds to step S92.

In step S92, the error check value generation unit 910 stores the control command received this time from the reception unit 600 and proceeds to step S93.
In step S93, the error check value generation unit 910 acquires the previously received control command already stored in the control command storage unit 920, generates an error check value using the previously received control command, and step Proceed to S94.

  In step S94, the error checking unit 640 collates the error check value acquired in step S91 with the error check value generated using the control command previously received by the error check value generation unit 910, and performs error check. If they are the same, the error checking unit 640 authenticates the validity of the control command received this time and the previous time (the result of step S95 is YES), and ends the processing according to this flowchart. If they are not identical, the error checking unit 640 determines that the control command is not valid and has an error (the result of step S95 is NO), proceeds to step S96, performs error detection notification, and according to this flowchart. The process ends. The error detection notification method is the same as in the first embodiment.

  In the present embodiment, as in the first embodiment, when the authentication process is performed between the main control unit 10 and the prize ball control unit 204, the process between the main control unit 10 and the effect control unit 203 is also performed. Since the procedure is almost the same as the authentication process, the description is omitted.

  As described above, in the present embodiment, the main control unit 10 stores control commands. And the main control part 10 produces | generates the error check value of the control command transmitted previously saved previously, adds to the control command transmitted this time, and transmits to the effect control part 203 as control command information. On the other hand, the effect control unit 203 stores a control command. Then, the effect control unit 203 performs error checking by comparing the error check value included in the control command information received this time with the error check value generated from the previously received control command that has already been stored. That is, similarly to the first embodiment, the gaming machine according to the present embodiment adds the error check value of the control command transmitted in the past to the control command to be transmitted this time and transmits it from the main control unit 10 to the effect control unit 203. doing. The gaming machine of the present embodiment configured as described above can obtain the same effects as the gaming machine 1 of the first embodiment.

[Hardware configuration of main controller]
Here, the gaming machine of the present embodiment can also be realized with a simple configuration, similarly to the gaming machine 1 of the first embodiment, and therefore can be easily realized by hardware or software. Hereinafter, an example of a configuration related to authentication of the main control unit when realized by hardware will be described. FIG. 22 is a configuration diagram illustrating an error check value generation / transmission unit (generation transmission circuit 10g) that is a configuration related to authentication of the main control unit 10.

  The error check value generation / transmission unit 1000 is a specific means for generating control command information and transmitting it to the effect control unit 203 based on an instruction from the CPU 10a, and includes a control circuit 1010 and a control command input / output unit 1020. , An error check value generation circuit 1030, a data transmission buffer 1040, and a data transmission circuit 1050 are provided.

  The control circuit 1010 is connected to the CPU through a control line, and controls the operation of each unit constituting the error check value generation / transmission unit 1000. The control command input / output unit 1020 includes a shift register or the like, and stores the control command transmitted this time output from the CPU 10a based on the data input / output instruction of the control circuit 1010, and the previously transmitted control that has been previously transmitted. The command is output to the error check value generation circuit 1030. Based on the generation circuit control instruction of the control circuit 1010, the error check value generation circuit 1030 generates an error check value using the previously transmitted control command output from the control command input / output unit 1020. The error check value generation circuit 1030 outputs the generated error check value to the data transmission buffer 1040. Here, the control command input / output unit 1020 corresponds to the control command storage unit 820 shown in FIG. Further, the error check value generation circuit 1030 corresponds to the error check value calculation unit 830 shown in FIG. Further, the control command input / output unit 1020 and the error check value generation circuit 1030 constitute an error check value generation unit 1060, which corresponds to the error check value generation unit 810 shown in FIG.

  The data transmission buffer 1040 is a storage area for temporarily storing the control command to be transmitted this time output from the CPU 10a and the error check value output from the error check generation unit 1030 together. The data transmission buffer 1040 outputs the control command temporarily stored based on the transmission control instruction of the control circuit 1010 and the error check value to the data transmission circuit 1050 together. The data transmission circuit 750 generates control command information using the control command output from the data transmission buffer 1040 and the error check value, and transmits the control command information to the effect control unit 203. Here, the data transmission buffer 1040 and the data transmission circuit 1050 correspond to the adding unit 540 and the transmission unit 550 shown in FIG.

  Note that the above-described hardware configuration is an example, and any hardware configuration that realizes the functions of the gaming machine of the present embodiment may be used. Although not particularly mentioned in the hardware configuration described above, the error check value generation / transmission unit 1000 may be configured as a one-chip microcomputer integrated with the CPU 10a, the ROM 10b, and the RAM 10c. When configured as a one-chip microcomputer, a control unit 1010, a data transmission buffer 1040, a transmission unit including the data transmission circuit 1050, and an error check value generation unit 1060 may be provided separately. Thus, by diverting the transmission unit of the existing one-chip microcomputer and adding the error check value generation unit 1060, it can be easily formed using the existing one-chip microcomputer.

  As mentioned above, although each embodiment which is an example of the game machine of this invention was described in detail, the game machine of this invention is not limited to the said embodiment. For example, in the above embodiment, as shown in FIG. 4, the control command transmitted this time is added with the control command transmitted last time, that is, the error check value of the control command transmitted one previous time to obtain control command information. However, the present invention is not limited to this, and the control command information is generated by adding the error check value of the control command transmitted n (n is an integer of 2 or more) previous to the control command transmitted this time. Also good. In this case, the control command to be transmitted to the 1st to n-th items may be obtained as control command information by adding dummy data of an error check value, an ID unique to the gaming machine or the like as an initial value. Further, in the case of the gaming machine of the first embodiment, it may be configured so that at least n error check values can be stored. Further, in the case of the gaming machine of the second embodiment, it may be configured so that at least n control commands can be stored.

  Specifically, the configuration of the control command information when n = 2, that is, when the error check value of the control command transmitted two times before is added to the control command transmitted this time will be described with reference to FIG. . As shown in FIG. 23, the control command information basically has a format in which an error check value of the control command transmitted two times before is added to the control command. However, a predetermined initial value 1 is added to the control command 1 transmitted first. An initial value 2 is added to the control command 2 transmitted second. Then, the error check value 1 of the control command 1 transmitted first is added to the control command 3 transmitted third, and control command information is generated. Similarly, the error check value 2 of the control command 2 transmitted second is added to the control command 4 transmitted fourth, and control command information is generated. Thereafter, control command information is generated in the same manner.

  In this way, by adding the error check value of the control command transmitted n times before to the control command transmitted this time, the relationship between the control command and the error check value added thereto may be made more difficult to analyze. it can. Thereby, even if an unauthorized person exploits control command information, it can be made more difficult to cheat.

  In the above embodiment, the error check value is generated by using both the MODE and DATA data of the control command. However, the gaming machine of the present invention is not limited to this. For example, the gaming machine of the present invention may generate the error check value using only the MODE information of the control command, that is, 1-byte data for identifying the control command classification.

  Furthermore, the gaming machine of the present invention may generate an error check value using a control command and an error check value added thereto. As a result, the error check value transmitted this time includes the information of the error check value added so far, that is, the control command information transmitted so far. Therefore, since the error check value includes information of the transmission history of the control command, even if an unauthorized person exploits some control command information, the error check value cannot be analyzed. Security strength can be improved. Further, since the error check value includes information on the transmission history of the control command, the continuity of the control command can be verified.

  A specific configuration for generating an error check value using a control command and an error check value added to the control command is, for example, as follows. In the error check value generation unit, the error check value generated from the previously transmitted control command is output from the error check value storage unit to the error check value calculation unit, and the control command transmitted this time and the output error check value are used. What is necessary is just to comprise so that an error check value calculating part produces | generates an error check value.

  The gaming machine of the present invention may generate an error check value using a plurality of control commands or control command information transmitted in the past. As a result, the relationship between the control command and the error check value added thereto can be made more difficult to analyze, and even if an unauthorized person exploits the control command information, it can be made more difficult to carry out fraud. .

  As a specific configuration for generating an error check value using a plurality of control commands transmitted in the past, for example, the following can be considered. The error check value generation unit includes a control command storage unit that stores a plurality of control commands output from the control command output unit, and the error check value calculation unit uses the plurality of control commands output from the control command storage unit. What is necessary is just to comprise so that an error check value may be produced | generated.

  In addition, a specific configuration for generating an error check value using a plurality of control command information transmitted in the past may be as follows, for example. The error check value generation unit includes a control command information storage unit that stores a plurality of control commands output from the control command output unit and the error check values generated by the error check value calculation unit as control command information. What is necessary is just to comprise so that an error check value calculating part produces | generates an error check value using the some control command output from the memory | storage part.

  As described above, the gaming machine of the present invention adds an error check value generated using at least a predetermined control command output in the past to the control command transmitted this time, to the control command output this time. As a result, the relationship between the control command and the error check value added thereto can be made more difficult to analyze, and even if an unauthorized person exploits the control command information, it can be difficult to perform fraud.

  Note that the gaming machine of the present invention may generate an error check value including a control command transmitted this time, in addition to a control command transmitted in the past, or a control command transmitted in the past and its error check value. Thereby, the communication error check of the control command received this time can be performed in real time using the error check value added to the control command received this time.

  As a specific configuration for generating the error check value including the control command to be transmitted this time, for example, the following can be considered. Provided with a storage unit for storing a plurality of control commands or control command information transmitted in the past, which is data for which error check values are generated, and a plurality of control commands or control command information output from the storage unit and control commands What is necessary is just to comprise so that an error check value may be produced | generated using the control command transmitted this time output from the output part.

  As described above, the gaming machine of the present invention can generate an error check value including a control command transmitted this time in addition to a control command transmitted in the past or a control command transmitted in the past and its error check value. However, from the viewpoint of improving the security strength, it is preferable to generate the error check value of the control command transmitted this time without using the control command itself transmitted this time. Specifically, it is preferable to generate an error check value to be added to the control command to be transmitted this time using a control command transmitted in the past or a control command transmitted in the past and its error check value. As described above, when the error check value is generated without using the control command transmitted this time, there is no relationship between the control command transmitted this time and the error check value added thereto. For this reason, even if an unauthorized person exploits two values of a control command and an error check value added thereto, the relationship cannot be analyzed. Therefore, it can be made more difficult for an unauthorized person to analyze the relationship between the control command and the error check value added thereto. In other words, even if an unauthorized person exploits the control command information, it is possible to make it more difficult to perform the fraud.

  In the above embodiment, the main control unit 10 includes the generation / transmission circuit 10g for generating an error check value. However, the main control unit 10 is not limited to this, and the same function is performed using the CPU 10a, the ROM 10b, and the RAM 10c. It may be realized. That is, in the present embodiment, the authentication function is realized by hardware, but is not limited thereto, and may be realized by software using the CPU 10a, the ROM 10b, and the RAM 10c.

  Moreover, you may combine the structure of the presentation control part 203 of 2nd Embodiment with the structure of the main control part 10 of 1st Embodiment. That is, the main control unit 10 may employ a configuration in which error check values are stored, and the effect control unit 203 may employ a configuration in which control commands are stored. Similarly, the configuration of the effect control unit 203 of the first embodiment may be combined with the configuration of the main control unit 10 of the second embodiment.

  Moreover, although the example which applies this invention to a pachinko game machine was shown in the said embodiment, it is not limited to this, This invention is a ball game machine other than pachinko game machines, such as a sparrow ball game machine and an arrangement ball. It can also be applied to other gaming machines such as slot machines such as slot machines. Also in these gaming machines, the same effects as in the above embodiment can be obtained by configuring in the same manner as in the above embodiment. Moreover, the said embodiment can divert each other's technique as long as there is no contradiction or a problem in particular in the objective, a structure, etc.
