(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, there are the following conventional gaming machines. That is, the gaming machine includes a main control unit (main control unit) storing third identification information and a first sub control unit (first control unit) connected to the main control unit and storing first identification information. 1 peripheral part) and a second sub-control part (second peripheral part) connected to the main control part and storing the second identification information. In this gaming machine, the first peripheral portion includes a computing unit that performs a predetermined computation using the first identification information, the second identification information, and the third identification information, and an illegal modification to the gaming machine based on the computation result of the computing unit. It has a means to discriminate | determine whether it was performed (for example, refer patent document 1). Hereinafter, this technique is referred to as a first conventional example.

  Also, the conventional gaming machine includes a main control device (main control unit) that transmits data to the symbol control unit according to the game situation, and a symbol display device based on control data received from the main control unit according to the game situation. Some have a symbol control section (peripheral section) for controlling the above. In this pachinko gaming machine, the main control unit performs encryption corresponding to the first key data on the first storage means for storing the first key data and the control data for controlling the operation of the symbol control unit. Encryption means and first key changing means for changing the first key data at a predetermined timing are provided.

Hereinafter, this technique is referred to as a third conventional example.

JP-A-2005-21330 JP 2002-210194 A JP 2008-279037 A

  In the first conventional example, the CPU mounted on the first peripheral portion performs predetermined calculation using the first identification information, the second identification information, and the third identification information, and is mounted on the second peripheral portion that controls the display. The determined CPU determines whether or not the gaming machine has been illegally modified based on the calculation result.

  As described above, in order to cause the CPU to execute the authentication process in addition to the existing process (for example, the effect process), it is necessary to add processes such as an authentication function and an authentication timing to the existing process. For this reason, much time and labor are required for the design and verification for adding the authentication function, and there is a problem that it takes a lot of time and effort to develop the gaming machine. Furthermore, with the recent diversification of the effects of gaming machines, the code size of programs to be executed by the CPU tends to become enormous, so that the above problem increases with the addition of the authentication function.

  In addition, when the CPU executes authentication processing in addition to existing processing, there is a problem in that the processing speed of the CPU is increased and the processing speed is reduced. In recent years, in particular, there is a tendency for various effects to appeal to the visual and auditory senses of players in order to improve the interest of the game, and the possibility that the above problems will occur increases.

  In the first conventional example, one CPU constituting the peripheral part performs only one authentication process (ID addition process). Further, by causing the CPU configuring the main control unit and the peripheral unit to execute the authentication process in addition to the existing processing, the processing load of the CPU configuring the main control unit and the peripheral unit increases. Therefore, it is difficult to cause the CPU configuring the main control unit and the peripheral unit to execute authentication processing by a more complicated calculation and authentication processing more than once in order to further enhance security.

  On the other hand, in the second conventional example, in the main control unit, the encryption means encrypts the control data corresponding to the first key data, and the first key change means sets the first key data at a predetermined timing. Has changed. The peripheral unit determines the validity of the received encrypted data by performing processing corresponding to the second key data on the encrypted data received by the authentication unit, authenticates the encrypted data if it is valid, The two-key changing means changes the second key data so as to correspond to the first key data at a predetermined timing so as to coincide with the change timing of the first key data. That is, the main control unit and the peripheral unit perform sophisticated and complicated encryption processing and authentication processing. Therefore, in the second conventional example, since the processing load of both the CPU constituting the main control unit and the CPU constituting the peripheral part increases, the processing speed decreases, and the basic process and the effect process accompanying the progress of the game content. The original process may not be performed smoothly.

  Further, in the third conventional example, as in the first conventional example, when the peripheral CPU executes an authentication process in addition to the existing game process, authentication data is added to a predetermined control command and the peripheral process is performed. Even if the data is transmitted to the part, the processing load on the CPU in the main control part and the peripheral part increases, so that it is considered that the processing speed is reduced and there is a design restriction that makes it difficult to add the authentication process itself.

  Further, by causing the CPU configuring the main control unit and the peripheral unit to execute the authentication process in addition to the existing processing, the capacity of the program executed by the CPU configuring the main control unit and the peripheral unit increases. Therefore, while maintaining the flexibility and expandability of software control, in order to further strengthen the security of the CPU that constitutes the main control unit and the peripheral unit, authentication processing by more complicated calculations and multiple times It is difficult to execute the authentication process.

  By the way, a gaming machine may malfunction when external electrical noise or mechanical vibration is applied. For example, when a control command is transmitted from the main control unit to the peripheral part, if noise such as electromagnetic waves or static electricity is added from the outside of the gaming machine, a bit error occurs in the control command data due to the influence of the noise, and control is performed. A malfunction occurs that the command is changed. However, in the first to third conventional examples, no countermeasures are taken for such a problem of malfunction, so the problem that the game shop suffers a great deal of damage cannot be solved.

  The present invention has been made in view of the above circumstances, and can detect an illegal act or malfunction of a gaming machine due to an exchange of a regular main control board and an unauthorized main control board of a gaming machine, and the main control unit and the surroundings. It is an object of the present invention to provide a gaming machine and a gaming machine authentication method that can reduce the processing load on the CPU of each section and have a high degree of design freedom when adding an authentication function.

  In order to solve the above-described problems, the present invention includes a main control unit (main control unit 10), a sub-control unit (peripheral unit 30) that performs processing according to predetermined information output by the main control unit, A gaming machine comprising intermediate control means (intermediate unit 20) provided between the control means and the sub-control means, wherein the main control means is an information storage unit in which predetermined game information is stored (Data storage unit 510), an arithmetic processing unit (main CPU core 500) that performs a predetermined calculation according to game information stored in the information storage unit, and an information transmission unit that transmits predetermined information to the intermediate control means (Transmission unit 520) and an authentication information generation unit that reads specific information stored in the information storage unit and generates authentication information for authenticating the validity of the information stored in the information storage unit (Encryption unit 530) and the previous An authentication information storage unit (authentication data storage area of the encryption unit 530) that stores the authentication information generated by the authentication information generation unit, and an authentication that causes the information transmission unit to transmit the authentication information stored in the authentication information storage unit An information transmission instruction unit (data input / output unit 532), and the arithmetic processing unit outputs a transmission instruction command for causing the information transmission unit to transmit information on a predetermined calculation result to the information transmission unit, When the transmission instruction command is input, the information transmission unit receives the information on the predetermined calculation result, transmits the received information on the predetermined calculation result to the intermediate control unit, and the authentication information transmission instruction unit The transmission instruction command output from the arithmetic processing unit to the information transmission unit is input, and when the transmission instruction command is input, the authentication information stored in the authentication information storage unit The information is transmitted to the information transmission unit, and the intermediate control unit receives the authentication information transmitted from the information transmission unit and authenticates the information stored in the information storage unit based on the received authentication information. To authenticate the validity of the main control means.

  According to the present invention, the encryption unit configured by the encryption control circuit (hardware) receives the authentication data necessary for the individual authentication of the main control unit according to the instruction from the main CPU core described in the program code. Instead, it is generated according to its own algorithm and automatically sent to the middle part. The key data necessary for decrypting the authentication data is output from the encryption control circuit only by a read instruction from the main CPU core, and transmitted to the intermediate unit. Therefore, while having an authentication function for the main control unit, it is possible to suppress the CPU processing load and program capacity of the main control unit, which increase by having the authentication function, to the maximum, and to improve the security strength of the pachinko gaming machine And improvement in processing speed can be achieved. In addition, according to the present invention, the setting of authentication data and key command transmission timing, key data update timing, etc. can be freely designed such as after a specific time or a specific number of clocks, and software control An authentication function with extensibility and flexibility can be provided.

  Further, according to the present invention, most of the authentication processing such as the authentication data decryption processing and the inspection value / expected value matching processing is executed by the intermediate section. Therefore, the production control unit executes the authentication process only when the authentication result data is received from the intermediate unit. That is, the processing load on the CPU of the production control unit increases only when the authentication result data is received by performing the authentication process, and thus the rate at which the processing load of the production control unit increases can be suppressed. Further, the program code related to the authentication result data analysis process need only be added to the program code executed by the effect control unit. Therefore, since it is not necessary to perform a new timing design over the entire program code executed by the production control unit, the timing design only needs to add the analysis function of the authentication result data, the implementation of the function, the verification of the function, etc. It can be carried out more easily and with less man-hours. This also increases the degree of design freedom when adding functions related to authentication processing.

  Here, the effect control unit 203, the prize ball control unit 204, and the lamp control unit 205 configured as described above are collectively referred to as the “peripheral unit 30”. In addition, the main control unit 10, the intermediate unit 20, the effect control unit 203, the prize ball control unit 204, and the lamp control unit 205 are different from each other (for example, the main control unit 10 is the main control board, The unit 20 is mounted on the intermediate board, the effect control unit 203 is mounted on the effect control board, the prize ball control unit 204 is mounted on the prize ball control board, and the lamp control unit 205 is mounted on the lamp control board. Among these, the effect control board, the prize ball control board, and the lamp control board are collectively referred to as “peripheral boards”. The intermediate unit 20 and the lamp control unit 205 can also be mounted on the same printed circuit board as the effect control unit 203. The prize ball control unit 204 can also be mounted on the same printed circuit board as the main control unit 10.

[Configuration for gaming machine authentication]
Next, means for realizing the authentication function that the pachinko gaming machine 1 having the above configuration has for preventing fraud will be described with reference to the drawings. The authentication function of the pachinko gaming machine 1 according to the present embodiment is realized by the intermediate unit 20 performing individual authentication with respect to the main control unit 10. Then, the authentication result obtained by the intermediate unit 20 is transmitted to the peripheral unit 30, and processing according to the authentication result received by the peripheral unit 30 is performed. In the present embodiment, the authentication result obtained by the intermediate unit 20 is described as being transmitted to the effect control unit 203 in the peripheral unit 30, and the effect control unit 203 performs processing according to the authentication result.

  Specifically, the test information and the expected value are obtained by using the unique information held by the main control unit 10 as the test value and the information corresponding to the information unique to the main control unit 10 stored in the intermediate unit 20 as the expected value. Is matched, it is determined that the individual authentication for the main control unit 10 is successful. The intermediate unit 20 transmits the obtained result of individual authentication for the main control unit 10 to the effect control unit 203. The effect control unit 203 refers to the authentication result transmitted from the intermediate unit 20, and performs processing according to the referred authentication result. Further, when executing the authentication process, the main control unit 10 generates a test value and transmits it to the intermediate unit 20, but performs an encryption process on the test value using an encryption key before transmission. The intermediate unit 20 performs a decryption process on the encrypted check value and extracts the check value. In the present embodiment, data obtained by performing the encryption process on the inspection value is referred to as “authentication data”. The encryption key used for the encryption process for the check value and the decryption key used for the decryption process for the authentication data are collectively referred to as “key data”.

  FIG. 3 is a block diagram showing an electrical configuration related to the authentication process of the main control unit 10 constituting the pachinko gaming machine 1 according to the embodiment of the present invention. The main control unit 10 includes at least a main CPU core 500, a data storage unit 510, a transmission unit 520, an encryption unit 530, a pulse generation unit 540, and an internal bus 550. Hereinafter, the main CPU core 500, the data storage unit 510, the transmission unit 520, the encryption unit 530, the pulse generation unit 540, or the internal bus 550 are collectively referred to as “components of the main control unit 10”.

  The main CPU core 500 controls basic operations accompanying the progress of the authentication process of the pachinko gaming machine 1. The main CPU core 500 executes various arithmetic processes that are performed when the authentication process proceeds based on a program code that is stored in the data storage unit 510 and describes processing contents and procedures related to the predetermined authentication process. For example, the main CPU core 500 executes a control command related to the authentication process, and instructs other circuits related to the authentication process of the main control unit 10 to control the authentication process. Note that the means for realizing the functions of the main CPU core 500 can be configured, for example, from a part of the CPU 10a shown in FIG.

  In the data storage unit 510, a program code related to authentication processing for the main CPU core 500 to execute authentication processing in the pachinko gaming machine 1 is stored in advance. Further, the data storage unit 510 stores test values used for individual authentication with respect to the main control unit 10. The data storage unit 510 transfers a program code and an inspection value related to the authentication process in accordance with a read instruction from the main CPU core 500 or the encryption unit 530. Here, “transfer” means movement of data and signals between the components of the main controller 10. Further, “delivery” means movement of data and signals in each component of the main control unit 10. “Transmission” means, for example, transmission of data and signals to the outside of the main control unit 10 (for example, the intermediate unit 20). Note that the means for realizing the functions of the data storage unit 510 can be configured, for example, from a part of the ROM 10b shown in FIG.

  The transmission unit 520 serves as an interface for transmitting control commands, data, and the like transferred from the main CPU core 500 and the encryption unit 530 to the effect control unit 203 via the intermediate unit 20 and the intermediate unit 20. For example, when the main CPU core 500 executes a control command related to authentication processing and causes the intermediate unit 20 to execute authentication processing, the transmission unit 520 sends control command data corresponding to the control command related to authentication processing from the main CPU core 500. receive. Then, the transmission unit 520 converts the received control command data into a control signal and transmits it to the intermediate unit 20. Note that the means for realizing the function of the transmission unit 520 can be configured by a known input / output device having the conversion function. However, transmission in only one direction from the main control unit 10 to the intermediate unit 20 is possible.

  The control signal means the control command data representing the contents of the control command, which is obtained by converting the data configured by adding an error detection code or the like into an electric signal. Hereinafter, the term “control command” In addition, not only the meaning of the control command to the intermediate unit 20 and the effect control unit 203 but also the meaning of the control command data and the control signal are included. In addition, transmitting a control signal to the intermediate unit 20 or the effect control unit 203 is simply referred to as “transmitting a control command”. “Writing a control command” is not limited to writing only control command data, and includes writing of data other than control command data constituting a control signal.

  The encryption unit 530 is so-called hardware, which generates key data as an encryption key when encrypting a test value according to an algorithm held by the encryption unit 530, and encrypts the test value transferred from the data storage unit 510. To generate authentication data. Then, the encryption unit 530 transfers the generated authentication data to the transmission unit 520 at a predetermined timing determined in advance, and causes the intermediate unit 20 to transmit the authentication data. Further, the encryption unit 530 transfers the generated key data to the main CPU core 500 in accordance with a read instruction from the main CPU core 500. Note that the means for realizing the functions of the encryption unit 530 can be configured by, for example, the encryption control circuit 10g shown in FIG.

  The pulse generation unit 540 sends a clock signal to the main CPU core 500, the transmission unit 520, and the encryption unit 530. The main CPU core 500 and the like connected to the pulse generator 540 synchronize operations with each other based on the received clock signal. Further, the main CPU core 500 or the like has a timer function for performing an interrupt process or the like by counting the clock signal received from the pulse generator. The means for realizing the functions of the pulse generator 540 can be configured from a known clock pulse generator. The internal bus 550 is a path through which constituent elements of the main control unit 10 such as data transfer between the main CPU core 500 and the encryption unit 530 exchange various data and signals. The internal bus 550 includes at least functions of an address bus and a data bus, and means for realizing the functions of the internal bus 550 can be configured by a known signal line.

Next, processing of each component of the main control unit 10 during authentication processing will be described. FIG. 4 is a block diagram for explaining the configuration of the main control unit 10 shown in FIG. 3 in detail.
After the pachinko gaming machine 1 is turned on and the main CPU core 500 performs an initial setting process, the encryption unit 530 constituting the main control unit 10 starts generating key data. The timing at which the encryption unit 530 starts generating the key data is set in advance by an algorithm held by the encryption unit 530 regardless of an instruction from the main CPU core 500. Specifically, the key determination unit 531 constituting the encryption unit 530 uses, as key data, a value generated by random number generation means held by itself such as a random number generation circuit (not shown) or a random number generation algorithm, for example. To do.

  Note that the key determination unit 531 may determine key data without using random numbers. For example, the key determination unit 531 holds a data table for determining key data in advance, and the key determination unit 531 obtains key data from the table according to a predetermined rule at the timing of generating the key data. You may make it acquire. Further, the key determination unit 531 may generate one key data at a time and determine the key data uniquely, or generate a plurality of key data at a time and select one key data from the plurality of key data. The key data used in the current authentication process may be determined. However, the timing for determining the key data used in the current authentication process is before the output of the key data to the main CPU core 500 described later.

  Subsequently, the encryption unit 530 takes in a test value used for performing individual authentication for the main control unit 10 from the data storage unit 510. Specifically, the encryption circuit 533 included in the encryption unit 530 causes the test value of the data storage circuit 511 included in the data storage unit 510 to be transferred via the internal bus 550 and the data input / output unit 532. Then, the encryption circuit 533 stores the inspection value written in the data input / output unit 532 in the inspection value storage area held by the encryption circuit 533 itself. The inspection value is not particularly limited as long as it is unique information held by the main control unit 10. For example, in addition to an identification number (ID) uniquely assigned to the main CPU core 500, data (control command data, instruction code, fixed data, etc.) stored at a specific address stored in the data storage circuit 511 ) Checksum etc. can be considered.

  The encryption circuit 533 reads the acquired inspection value from the inspection value storage area, performs encryption processing using the key data generated by the key determination unit 531 in advance, and generates authentication data. The calculation method of the encryption process (hereinafter referred to as “encryption method”) is not particularly limited as long as it is determined in advance between the main control unit 10 and the intermediate unit 20 or the effect control unit 203. The encryption method is obtained by, for example, a processing method for obtaining arithmetic data having a predetermined data length by performing four arithmetic operations or logical operations using the inspection value and the key data, and these four arithmetic operations or logical operations. A processing method for rearranging the bit array of operation data, a processing method for shifting or rotating the bits of the operation data, a processing method for extracting a plurality of bits constituting a test value and arranging them according to a predetermined rule to generate one data is there.

  When generating the authentication data, the encryption circuit 533 stores the authentication data in its own authentication data storage area, and holds it until the authentication data is transmitted to the intermediate unit 20. The encryption circuit 533 sets the transmission timing of the authentication data to the intermediate unit 20. The transmission timing of the authentication data is set in advance by an algorithm held by the encryption unit 530 regardless of an instruction from the main CPU core 500. The encryption circuit 533 transfers the authentication data to the transmission unit 520 constituting the main control unit 10 via the data input / output unit 532 and the internal bus 550 and transmits the authentication data to the intermediate unit 20 at the authentication data transmission timing. Specifically, the encryption circuit 533 delivers the generated authentication data to the data input / output unit 532 at the authentication data transmission timing. The data input unit 532 immediately writes the passed authentication data to the data input unit 522 constituting the transmission unit 520 via the internal bus 550. Note that the timing at which the key determination unit 531 generates key data and the timing at which the encryption circuit 533 acquires the inspection value are not particularly limited as long as the encryption circuit 533 does not pass the authentication data to the data input / output unit 532. . Further, the transmission timing of the authentication data and the configuration of the transmission unit 520 will be described later.

  On the other hand, the main CPU core 500 constituting the main control unit 10 executes a key command serving as a trigger for causing the intermediate unit 20 to start an authentication process. Specifically, the processing unit 501 constituting the main CPU core 500 acquires key data necessary for executing a key command according to a program code related to authentication processing. More specifically, the processing unit 501 configuring the main CPU core 500 acquires the key data determined by the key determining unit 531, the data input / output unit 502 configuring the main CPU core 500, the internal bus 550, The key determination unit 531 is instructed to read out key data via the data input / output unit 532. Upon receiving the key data read instruction from the processing unit 501, the key determination unit 531 delivers the predetermined key data to the data input / output unit 532. The data input / output unit 532 immediately outputs the received key data to the data input / output unit 502 via the internal bus 550. The data input / output unit 502 delivers the output key data to the processing unit 501. The processing unit 501 generates a key command using the received key data and immediately writes it to the data input unit 522 constituting the transmission unit 520 via the internal bus 550 and the data input / output unit 502. Details of the key command and its transmission timing will be described later.

  When data is transferred from each component of the main controller 10, the transmitter 520 immediately transmits the received data to the intermediate unit 20. For example, when a control command is written from the main CPU core 500 to the data input unit 522 configuring the transmission unit 520 via the internal bus 550, the data input unit 522 immediately transfers the written control command to the transmission circuit 521. . The transmission circuit 521 immediately transmits the received control command to the intermediate unit 20 as transmission data.

  When each component of the main control unit 10 writes data to the data input unit 522, each data is written simultaneously with the data to be written to the data input unit 522 so that the internal bus 550 does not collide with other data. A write signal is output from the component. The internal bus 550 assigns data passing through the internal bus 550 through the output write signal. Other components that have not output the write signal can know what data is being written to the data input unit 522 by referring to the write signal communicated to the internal bus 550. For example, when a control signal is written from the main CPU core 500 to the data input unit 522, when a write signal indicating that is output, the encryption unit 530 refers to the write signal and currently reads the main CPU core. It can be seen that 500 is writing a control command to the data input unit 522.

  On the other hand, when data to be written to the data input unit 522 and a write signal indicating that are input via the internal bus 550, the transmission unit 530 reads the data from the internal bus 550 and writes it to the data input unit 522. Then, when data is written in the data input unit 522, the transmission unit 530 transfers the written data to the transmission circuit 521, configures transmission data, and immediately transmits the data to the intermediate unit 20. Therefore, for example, the encryption unit 530 can know the control command transmission timing of the main CPU core 500 by referring to the control command write signal of the main CPU core 500.

  Next, the types of control commands transmitted from the main control unit 10 to the intermediate unit 20 or to the effect control unit 203 via the intermediate unit 20 will be described. FIG. 5 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 command types shown in FIG. It is not limited. The control command transmitted from the main control unit 10 to the effect control unit 203 via the intermediate unit 20 or the intermediate unit 20 is composed of 2 bytes of data, and 1 for identifying the control command classification. It consists of byte MODE information and 1-byte DATA information indicating the detailed control contents of each control command. Note that BCC (Block Check Character) or the like may be added to the control command in the same manner as a signal transmitted in general data communication. The BCC is an error detection code added to each transmission block in order to check data errors that occur in the data transmission process.

  The MODE information and DATA information are stored in advance in the data storage circuit 511 of the data storage unit 510 for control commands (hereinafter referred to as normal control commands) used for normal game processing other than key commands. In the case of a key command, the information of “MODE” is the same as that of a normal control command (for example, assigned to “E8H” in FIG. 5). On the other hand, the information of “DATA” is 1-byte key data determined before the key data output to the main CPU core 500 from the key determination unit 531 constituting the encryption unit 530 (for example, “DATA” in FIG. ○ × H ”) is used. The key data is appropriately updated at a timing set in advance in the key determination unit 531. Therefore, at least the amount of information that can be taken by the key data at the time of updating the key data is prepared as the type of information of “DATA” constituting the key command. For example, “○ × It is appropriately changed such as “H” → “ΔH” → “□ × H”.

The “power-on command” indicates that the power of the pachinko gaming machine 1 is turned on, “MODE” is set to “E1H”, and “DATA” is set to “00H”.
This power-on command is transmitted to the effect control unit 203 via the intermediate unit 20 and the intermediate unit 20 when the pachinko gaming machine 1 is powered on. Specifically, when the power of the pachinko gaming machine 1 is turned on, the processing unit 501 of the main CPU core 500 that constitutes the main control unit 10 sends a write signal to the data input unit 522 that constitutes the transmission unit 520. In addition to outputting, a power-on command is written in the storage area of the data input unit 522. Thereafter, the data input unit 522 immediately transfers the written power-on command to the transmission circuit 521. The transmission circuit 521 immediately transmits the received power-on command as transmission data to the intermediate unit 20. As described above, when the control command is transmitted to the effect control unit 203 via the intermediate unit 20 or the intermediate unit 20, a write signal is output to the data input unit 522 constituting the transmission unit 520, and the control command is transmitted to the data input unit. Writing to the storage area 522 and transferring it to the transmission circuit 521 as transmission data is hereinafter simply referred to as “setting a control command”.

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 displayed in the intermediate section 20 when a predetermined time elapses after the demonstration is started as the initial effect display displayed when the power is turned on, or after the number of undrawn winning prizes described later becomes zero and the demonstration is started. Is transmitted to the effect control unit 203. Specifically, a customer waiting demo command is set in the transmission unit 520 after a predetermined time elapses after the demonstration is started. Thereafter, the customer waiting demonstration command set in the transmission unit 520 is immediately transmitted to the effect control unit 203 via the intermediate unit 20.

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.
This symbol variation pattern command is transmitted to the effect control unit 203 via the intermediate unit 20 when various symbol variation patterns after the jackpot determination at the time of winning lottery are determined. Specifically, it is determined whether or not 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 set in the transmission unit 520. Thereafter, the symbol variation pattern command set in the transmission unit 520 is immediately transmitted to the effect control unit 203 via the intermediate unit 20.

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 via the intermediate unit 20 after the symbol variation has started and the symbol variation time has elapsed. Specifically, the symbol stop command is set in the transmission unit 520 when the symbol variation is stopped because a predetermined symbol variation time has elapsed after the symbol variation is started. Thereafter, the symbol stop command set in the transmission unit 520 is immediately transmitted to the effect control unit 203 via the intermediate unit 20.

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.
As for the jackpot start command, when various jackpots start, the jackpot start command corresponding to the jackpot type is transmitted to the effect control unit 203 via the intermediate unit 20. Specifically, when the jackpot game process is started, a jackpot start command corresponding to the jackpot type is set in the transmission unit 520. Thereafter, the jackpot start command set in the transmission unit 520 is immediately transmitted to the effect control unit 203 via the intermediate unit 20.

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 via the intermediate unit 20. Specifically, when the first big prize opening opening / closing door 109a or the second big prize opening opening / closing door 129a is opened, a jackpot command corresponding to the number of rounds to be opened is set in the transmission unit 520. Thereafter, the jackpot command set in the transmission unit 520 is immediately transmitted to the effect control unit 203 via the intermediate unit 20.

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 via the intermediate unit 20 when the various jackpots end. Specifically, a jackpot end command corresponding to the jackpot type is set in the transmission unit 520 at the start of the jackpot game end process. Thereafter, the jackpot end command set in the transmission unit 520 is immediately transmitted to the effect control unit 203 via the intermediate unit 20.

The “key command” indicates that the authentication data is decrypted in order to execute the authentication process in the pachinko gaming machine 1, and “MODE” is set to “E8H”, and various types of keys determined by the key determination unit 531. DATA information is set according to the key data.
This key command is transmitted to the intermediate unit 20 when the pachinko gaming machine 1 executes an authentication process. When receiving the key command from the main control unit 10, the intermediate unit 20 decrypts the authentication data using the key command, starts an authentication process, and transmits the obtained authentication result to the effect control unit 203. The effect control unit 203 performs processing according to the authentication result transmitted from the intermediate unit 20. The timing at which the pachinko gaming machine 1 executes the authentication process can basically be set arbitrarily. However, in the effect control unit 203, it is necessary to execute the effect process as the normal game progresses in addition to the authentication process, so it is desirable to suppress the processing load of the authentication process in the effect control unit 203 as much as possible. Therefore, for example, when the power is turned on or the customer waiting demonstration is started, it is conceivable that the pachinko gaming machine 1 executes the authentication process.

For example, when the transmission timing of the key command is set to when the power is turned on, the main CPU core 500 is acquired from the key determination unit 531 after a predetermined time has elapsed since the power-on command was set in the transmission unit 520. A key command is constructed using the key data and set in the transmission unit 520. Thereafter, the key command set in the transmission unit 520 is immediately transmitted to the intermediate unit 20.
Further, for example, when the transmission timing of the key command is set to the time when the customer waiting demo is started, the key command is received from the key determining unit 531 after a predetermined time has elapsed since the customer waiting demo command was set in the transmitting unit 520. It is configured using the acquired key data and is set in the transmission unit 520. Thereafter, the key command set in the transmission unit 520 is immediately transmitted to the intermediate unit 20. In the following description of the present embodiment, it is assumed that a key command is transmitted when the power is turned on.

[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 control commands to the intermediate unit 20 and the effect control unit 203 by the main control unit 10 will be described with reference to a flowchart shown in FIG. The main CPU core 500, which is a component of the main control unit 10, executes a control command every predetermined period (for example, 4 milliseconds) based on the clock signal output from the clock pulse generation circuit 541 of the pulse generation unit 540. And so on.

  In step S1, first, the main CPU core 500 constituting the main control unit 10 executes an initial setting process associated with power-on of the pachinko gaming machine 1, and then proceeds to step S2. When the pachinko gaming machine 1 is turned on, the peripheral board and the like are started up to initialize the RAM area in order to reliably capture the control command received from the main control board by the peripheral board and the like. After entering the state, the main control board is configured to stand up. As an initial setting process, the main CPU core 500 sets, for example, a predetermined value in a stack pointer, and waits for the intermediate unit 20 and the effect control unit 203 to enter a standby state (for example, , About 1 second).

  In step S <b> 2, the main CPU core 500 sets the power-on command shown in FIG. 5 in the transmission unit 520 and transmits it to the intermediate unit 20. After setting the power-on command, the main CPU core 500 proceeds to step S3. When the power-on command is received, the intermediate unit 20 sends a control command for the effect at power-on to each of the symbol display unit 104 and the lamp control unit 205 via the effect control unit 203 and the effect control unit 203. In this case, the gaming machine transmits a customer waiting demonstration command for displaying a demonstration screen waiting for a customer in a non-gaming state, or a control command for lighting a lamp or the like.

  The power-on command indicates a control command for executing processing associated with power-on after power-on. After each control board is started up, effect control is performed from the main control unit 10 via the intermediate unit 20 or the intermediate unit 20. Control command transmitted to the unit 203, etc., and initial control information for controlling a game at the time of start-up after power-on, for example, a control command for transmitting a control mode, backup data, etc., or an initial effect A control command for controlling display and a control command for starting various demonstration displays. The power-on command also includes a control command for transmitting the control mode, backup data, etc., which is executed when the reset button of the gaming machine is pressed.

  Here, when the transmission timing of the key command is set to when the power is turned on, the main CPU core 500 performs an interrupt process based on the clock signal from the pulse generator 540 after step S2. After a predetermined time has elapsed since the power-on command was set in the transmission unit 520, a key command is configured using the key data acquired from the key determination unit 531 and set in the transmission unit 520. Thereafter, the key command set in the transmission unit 520 is immediately transmitted to the intermediate unit 20, and authentication processing is started in the intermediate unit 20. Details of the authentication process will be described later.

  In step S <b> 3, the main CPU core 500 refers to the unlottery winning number data stored in the RAM 10 c and determines whether or not the number of undrawn winning prizes is zero. 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 CPU core 500 proceeds to step S10 described later. On the other hand, if the determination result in step S3 is “YES”, that is, if the number of undrawn prizes is 0, the main CPU core 500 proceeds to step S4.

In step S4, the main CPU core 500 measures the time that has elapsed since the start-up demonstration was started, and then proceeds to step S5.
In step S5, the main CPU core 500 determines whether or not a predetermined time has elapsed since the demonstration at the time of power-on 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 CPU core 500 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 CPU core 500 sets the customer waiting demo command in the transmission unit 520 and transmits it to the effect control unit 203 via the intermediate unit 20, 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 the predetermined time has not elapsed since the start of the power-on demo (or the customer waiting demo), the main CPU core 500 executes the step Proceed to S7.
In step S <b> 7, the main CPU core 500 detects whether or not 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 that the second start port 120 has entered 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 the entry of a game ball into the mouth 120 is detected, the main CPU core 500 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 When the game ball is not detected to enter the second start port 120, the main CPU core 500 returns to step S4 and repeats the processes after step S4.

In step S8, the main CPU core 500 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 CPU core 500 adds 1 to the number of undrawn prizes. If the first start port detection unit 221 or the second start port detection unit 225 detects a plurality of game balls entering, in this step S9, the main CPU core 500 enters the number of undrawn winning prizes. Add the corresponding numbers. Then, the main CPU core 500 proceeds to step S10.

In step S10, the main CPU core 500 randomly obtains 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 CPU core 500 subtracts 1 from the number of undrawn winning prizes, and then proceeds to step S12.

  In step S12, the main CPU core 500 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, if the acquired big hit determination random number is an out-of-order random number, the main CPU core 500 refers to, for example, the big hit determination data table, 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 CPU core 500 proceeds to step S13.

In step S13, the main CPU core 500 determines, for example, a symbol variation command (bonus 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 via the intermediate unit 20, and then the process proceeds to step S14.
In step S14, the main CPU core 500 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 CPU core 500 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S14 is “YES”, and the main CPU core 500 proceeds to step S15.

In step S15, the main CPU core 500 sets a symbol stop command to the transmission unit 520, transmits it to the effect control unit 203 via the intermediate unit 20, and then proceeds to step S16.
In step S <b> 16, the main CPU core 500 sets a jackpot start command to the transmission unit 520, transmits it to the effect control unit 203 via the intermediate unit 20, and then proceeds to step S <b> 17.
In step S17, the main CPU core 500 sets a command corresponding to each of the big hits (a big hit command) to the transmission unit 520, and sequentially transmits it to the effect control unit 203 via the intermediate unit 20, and all the rounds After sending the jackpot command, the process proceeds to step S18.
In step S18, the main CPU core 500 sets a jackpot end command to the transmission unit 520, transmits it to the effect control unit 203 via the intermediate unit 20, 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 CPU core 500 proceeds to step S19.
In step S19, the main CPU core 500 displays 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”. A symbol variation pattern command (outgoing command) corresponding to “no reach” is set in the transmission unit 520 and transmitted to the effect control unit 203 via the intermediate unit 20, and then the process proceeds to step S20.

In step S20, the main CPU core 500 determines whether or not the symbol variation time has elapsed. If the determination result in step S20 is “NO”, that is, if the symbol variation time has not elapsed, the main CPU core 500 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S20 is “YES”, and the main CPU core 500 proceeds to step S21.
In step S21, the main CPU core 500 sets a symbol stop command to the transmission unit 520, transmits it to the effect control unit 203 via the intermediate unit 20, and then proceeds to step S22.

  In step S22, the main CPU core 500 determines whether or not the power of the pachinko gaming machine 1 is 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 CPU core 500 returns to step S3 and repeats the processes after step S3.

On the other hand, if the determination result in step S22 is “YES”, that is, if the power of the pachinko gaming machine 1 is turned off, the main CPU core 500 proceeds to step S23.
In step S <b> 23, the main CPU core 500 sets an end process command to the transmission unit 520 and transmits it to the effect control unit 203 via the intermediate unit 20, and then ends the process according to this flowchart.

Hereinafter, an authentication process performed between the main control unit 10, the intermediate unit 20, and the effect control unit 203 will be described.
FIG. 7 is a flowchart illustrating an example of a procedure of authentication processing by the main control unit 10.
In step S101, after the main control unit 10 is turned on and the initial setting process is performed, the encryption unit 530 is used for the current authentication process according to the algorithm held by the encryption unit 530 regardless of an instruction from the main CPU core 500. The key data to be determined is determined. The key determination unit 531 constituting the encryption unit 530 can use, for example, a random number value generated by a random number generation unit or the like as key data. The key determination unit 531 writes the determined key data in its own key data storage area and transfers it to the encryption circuit 533. The encryption circuit 533 writes the received key data in its own key data storage area.

  In step S102, the encryption unit 530 takes in the inspection value stored in the data storage unit 510, performs encryption processing on the inspection value, and generates authentication data. Specifically, the encryption circuit 533 constituting the encryption unit 530 transfers the data stored at a specific address of the data storage circuit 511 constituting the data storage unit 510 via the data input / output unit 532 and the internal bus 550. Read out. Then, the encryption circuit 533 stores the read inspection value in its own inspection value storage area and takes in the inspection value.

  In step S <b> 103, the encryption unit 530 performs encryption processing on the acquired inspection value and generates authentication data. Specifically, the encryption circuit 533 reads the key data received from the key determination unit 531 in step 101 from its own key data storage area, and sets the read key data for the inspection value to a preset encryption method. Calculate with. The encryption circuit 533 stores the calculation result as authentication data in the authentication data storage area and holds it until the transmission timing of the authentication data.

  In step S104, the main CPU core 500 executes an initial setting process after power-on, and then writes the control command (power-on command) in the data input unit 522 constituting the transmission unit 520 to transmit the control command (power-on command) to the intermediate unit 20. . Specifically, the processing unit 501 of the main CPU core 500 takes in a control command (power-on command) stored in the data storage circuit 511 via the data input / output unit 502 and the internal bus 550. Then, the processing unit 501 outputs a write signal for writing the fetched control command (power-on command) to the data input unit 522 to the internal bus 550 via the data input / output unit 502. Then, the processing unit 501 writes the control command (power-on command) to the storage area of the data input unit 522 via the data input / output unit 502 and the internal bus 550, and sets the control command (power-on command).

  In step S105, when a control command (power-on command) is written in the data input unit 522, the transmission unit 520 immediately transmits it to the intermediate unit 20. Specifically, the data input unit 522 configuring the transmission unit 520 transfers the control command (power-on command) written in step S104 to the transmission circuit 521. The transmission circuit 521 immediately transmits the transferred control command (power-on command) to the intermediate unit 20.

  In step S106, the encryption unit 530 transmits the authentication data on the assumption that the main CPU core 500 transmits the authentication data to the intermediate unit 20 after a specific time has elapsed since the main CPU core 500 wrote the control command (power-on command) to the data input unit 522. Set the timing. Specifically, the encryption circuit 533 refers to a write signal output when the main CPU core 500 writes a control command (power-on command) to the data input unit 522 in step S104. Then, the encryption circuit 533 sets the authentication data generated in step S103 to be written in the storage area of the data input / output unit 522 at a timing after the elapse of a specific time (for example, 2 milliseconds) from the output of the write signal.

In step S107, the encryption unit 530 writes the authentication data to the data input unit 522 after a specific time has elapsed.
In step S <b> 108, the transmission unit 520 transmits the authentication data to the intermediate unit 20 as soon as the authentication data is written in the data input unit 522. Specifically, the data input unit 522 constituting the transmission unit 520 transfers the authentication data written in step S107 to the transmission circuit 521. The transmission circuit 521 immediately transmits the passed authentication data to the intermediate unit 20. The timing at which the encryption circuit 533 writes the authentication data to the data input / output unit 522 after a specific time has elapsed from the control command write signal will be described later.

  Further, the main CPU core 500 executes a control command every predetermined cycle (for example, 4 milliseconds). The main CPU core 500 executes the key command after, for example, 4 milliseconds have elapsed since the transmission of the control command (power-on command). Specifically, the following steps S109 to S111 are performed.

In step S109, first, the processing unit 501 of the main CPU core 500 instructs the key determination unit 531 of the encryption unit 530 to read out key data.
In step S110, when the key determination unit 531 receives a key data read instruction from the processing unit 501, the key determination unit 531 reads the key data determined in step S101 from the key data storage area, and stores the data input / output unit 532 and the internal bus 550. To the data input / output unit 502 of the main CPU core 500. The data input / output unit 502 delivers the output key data to the processing unit 501.
In step S111, the processing unit 501 generates a key command using the received key data, and immediately writes the key command in the storage area of the data input unit 522 via the data input / output unit 502 and the internal bus 550. set.

  In step S112, when the key command is written in the data input unit 522, the transmission unit 520 immediately transmits it to the intermediate unit 20. Specifically, the data input unit 522 constituting the transmission unit 520 transfers the key command written in step S111 to the transmission circuit 521. The transmission circuit 521 immediately transmits the passed key command to the intermediate unit 20. Note that the processing unit 501 outputs a write signal when writing the key command to the data input unit 522, as in step S104. Similarly to step S106, the encryption circuit 533 can determine the transmission timing of authentication data used for the next authentication process based on the output of the write signal in step 111.

  In step S113, the encryption unit 530 updates the key data using the same method as in step S101. The update timing of the key data is after step S110, that is, after the encryption unit 530 outputs the key data in step 110 in response to the key data read instruction from the main CPU core 500 in step S109. And The update timing of the key data will be described later.

  Next, the transmission timing of the key command and the authentication data of the main control unit 10 when the pachinko gaming machine 1 executes the authentication process when the power-on command described in FIG. 7 is transmitted will be described with reference to FIG. The horizontal axis in FIG. 8 represents the time axis. In FIG. 8, description of initialization processing such as initialization processing of the RAM area immediately after power-on and standby processing for stabilizing operation is omitted. The main control unit 10 will be described on the assumption that the operation start time of each component unit is synchronized when the clock signal rises.

  As shown in FIG. 8A, when the main control unit 10 is powered on, key data is determined by the encryption unit 530 independently of the main CPU core 500, and authentication data is generated. The The authentication data generated at the time of (a) is referred to as authentication data (A). Then, as shown in FIG. 8B, a control command (power-on command) is executed in the main CPU core 500. Specifically, the main CPU core 500 outputs a write signal to the transmission unit 520 and writes a control command (power-on command). Then, as shown in FIG. 8C, transmission of the control command (power-on command) written in the transmission unit 520 to the intermediate unit 20 is immediately started.

  Here, in the main CPU core 500 of the main control unit 10, a control command is executed every predetermined cycle. In FIG. 8, the execution cycle of this control command is schematically described as the number of clocks = 16 clocks. ing. Therefore, the operation of the main CPU core 500 is counted from the time when the control command (power-on command) shown at the time (a) is written, and the next operation is started at the 16th clock.

  Also, as shown in (c), the encryption unit 530 sets the transmission timing of the authentication data with the output of the write signal at (i) as a trigger. The transmission timing of the authentication data is set to a timing at which the authentication data is transmitted by interrupting each control command transmitted by the main CPU core 500 at a predetermined cycle. Further, at the time when the authentication data is transmitted, specifically, at the time when the encryption unit 530 writes the authentication data to the transmission unit 520 (the time of (e) in FIG. 8), other transmission data is stored in the transmission unit 520. It should not be stagnant. That is, as shown in FIG. 8 (e), the authentication data is written to the transmission unit 520 after the transmission of the control command in the transmission unit 520 is completed (time (d) in FIG. 8). In addition, it is necessary to set the transmission timing of authentication data.

  Therefore, the transmission timing of the authentication data, that is, the timing at which the encryption unit 530 writes the authentication data to the transmission unit 520 is after the write signal when the control command is written to the transmission unit 520 in the main CPU core 500 is output. (In FIG. 8, the time point after (c)) and before the execution of the next control command of the main CPU core 500 (in FIG. 8, time point (c)), the transmission of the authentication data is completed (FIG. 8). Then, set to a possible timing. In FIG. 8, the transmission timing of the authentication data is, for example, the time point (e) of the eighth clock from the point (c). Then, as shown at (e) in FIG. 8, the authentication data (A) is written into the transmitting unit 520 by the encryption unit 530 at the eighth clock from the time (c). Thereafter, as shown in FIG. 8F, transmission of the authentication data (A) written in the transmission unit 520 to the intermediate unit 20 is immediately started.

  By setting the transmission timing of the authentication data as described above, the timing of writing the authentication data and other transmission data (in the above example, the control command) to the transmission unit 520 overlaps, and the authentication data or other transmission data is The possibility of being overwritten and causing a transmission error can be reduced. This prevents the decryption process from being disabled due to a mismatch between the authentication data and the key data during the authentication process in the intermediate unit 20, and improves the accuracy of the authentication process. Also, by setting the authentication data transmission timing as described above, the positional relationship on the time axis between the authentication data transmission timing and the control command transmission timing is clarified. This must be done immediately after. As a result, the intermediate unit 20 can easily identify the authentication data and the control command without providing a new determination processing step or special analysis means when analyzing the type of received data. In addition, this makes it possible to add a function related to the transmission of authentication data while maintaining a low degree of coupling of the code related to the transmission of the authentication data with respect to the existing program code related to the transmission of the control command in software development. Thus, for example, during debugging, only work related to transmission of existing control commands can be performed first, and work related to transmission of authentication data can be performed later. Can be implemented.

  Subsequently, as shown in FIG. 8 (c), the main CPU core 500 reads the key data in order to start the execution of the key command at the 16th clock from the time (b). An instruction is given to the encryption unit 530. Then, as shown in FIG. 8 (K), when the encryption unit 530 receives a key data read instruction, the key data is immediately output to the main CPU core 500. Since this key data is the same as the key data used when the authentication data (A) is generated, it is assumed to be key data (A). When the main CPU core 500 receives the key data (A), the key command is immediately executed as shown in FIG. Specifically, the main CPU core 500 outputs a write signal to the transmission unit 520 and writes a key command composed of key data (A). Then, as shown at the point (S) in FIG. 8, the key command composed of the key data (A) written in the transmission unit 520 is immediately started to be transmitted to the intermediate unit 20.

  Then, the key data is updated as shown in FIG. Here, it is assumed that the key data (A) is changed to the key data (B). Here, the update timing of the key data is the time after the encryption unit 530 outputs the key data in response to the key data read instruction from the main CPU core 500 (time of (c) in FIG. 8). Is set after the lapse of the specified time. If the update timing of the key data is set before the point (C) in FIG. 8, the key data used for generating the authentication data transmitted at the point (F) and the key data transmitted at the point (S) There is a risk that the key data constituting the key command will not match. Then, even if the intermediate unit 20 receives the key command and starts the authentication process, the authentication data cannot be decrypted. Therefore, the update timing of the key data is after the time after the encryption unit 530 outputs the key data in response to the read instruction of the key data from the main CPU core 500 (the time of (C) in FIG. 8). And

  By setting the update timing of the key data as described above, it is possible to prevent the decryption process from being disabled due to a mismatch between the authentication data and the key data during the authentication process in the intermediate unit 20. Accuracy can be improved.

  Thereafter, as shown in FIG. 8 (S), the authentication unit 530 generates authentication data for the second time. Since this authentication data is generated by using the key data (B) updated at the time (S), it is assumed to be authentication data (B). Then, as shown in FIG. 8 (C), as in the case of writing the authentication data (A), the encryption unit 530 counts the authentication data at the 8th clock from the time (S). (B) is written in the transmission unit 520. Thereafter, as shown in FIG. 8 (So), the authentication data (B) written in the transmission unit 520 immediately starts to be transmitted to the intermediate unit 20, and is transmitted at the time (T) in FIG. Is completed.

  Subsequently, as shown in FIG. 8 (h), the main CPU core 500 reads the key data to start execution of the key command at the 16th clock from the time (c). An instruction is given to the encryption unit 530. Then, as shown in FIG. 8 (tsu), when the encryption unit 530 receives a key data read instruction, the key data (B) is immediately output to the main CPU core 500. When the main CPU core 500 receives the key data (B), the key command is immediately executed as shown in FIG. Specifically, the main CPU core 500 outputs a write signal to the transmission unit 520 and writes a key command composed of key data (B). Then, as shown in FIG. 8G, the key command composed of the key data (B) written in the transmission unit 520 is immediately started to be transmitted to the intermediate unit 20, and ( The transmission is completed at the time of na).

  FIG. 8 shows the time until the key command is transmitted twice at a predetermined cycle when the power-on command that triggers transmission of the key command is transmitted once. Needless to say, the key command may be transmitted. FIG. 8 shows an example in which a cycle based on the number of clocks is used as the predetermined cycle. However, a cycle based on a predetermined time, a predetermined number of transmissions of control commands, or the like may be used. Also, the control command that triggers the transmission of the key command need not be limited to one type of control command. For example, when triggered by two or more types of control commands, a power-on command and a customer waiting demo command. You may comprise. Further, the control command that triggers the transmission of the key command may be configured to be changed according to a preset rule. In FIG. 8, the authentication data is sequentially transmitted every time a control command that triggers transmission of a key command is transmitted. For example, when a control command that triggers transmission of a key command is transmitted twice. The authentication data (and key command) may be sent only once.

  Further, in FIG. 8, when setting the transmission timing of the authentication data, a specific time has elapsed with reference to the write signal of the control command that triggers the transmission of the key command (in FIG. 8, 8 from the point of (c)). The transmission timing is set so that the writing of the authentication data is started after reaching the time point (e) located at the clock. However, the present invention is not limited to this, for example, after a specific number of clocks has elapsed or a specific number of times the number of control command transmissions has elapsed with reference to a write signal of a control command that triggers transmission of a key command. And so on. That is, the transmission timing of the authentication data may be a timing that is delayed by a specific time from the transmission of the control command that triggers the transmission of the key command so that the timing of writing to the transmission unit 520 does not overlap. Further, the transmission timing of the authentication data can be based not only on the write signal of the control command that triggers the transmission of the key command but also on the basis that the transmission flag is set. In this case, it is possible to write the authentication data immediately after confirming that the transmission flag is set, as well as writing the authentication data after the elapse of the specific time.

  In FIG. 8, when setting the update timing of the key data, the update is performed so that the authentication data is generated with the new key data every time the transmission of the authentication data and the transmission of the key command are completed once. Timing is set. Then, after a specified time has elapsed with reference to the key data output of the encryption unit 530 in response to the key data read instruction from the main CPU core 500 (in FIG. After reaching the time point, the update timing of the key data is set. However, the present invention is not limited to this, for example, after a specified number of clocks has elapsed or a specified number of control command transmissions have elapsed, with reference to the output of key data in response to a key data read instruction. It is good.

  Hereinafter, the operation process including the authentication process by the intermediate unit 20 will be described with reference to the flowchart shown in FIG. A CPU core (not shown) constituting the CPU 20a of the intermediate unit 20 is based on a clock signal output from a clock pulse generation circuit (not shown) provided in the intermediate unit 20, for a predetermined period (for example, 2 mm). Every second), processing according to the control command is performed.

  In step S201, the CPU core of the intermediate unit 20 first receives the transmission data (various control commands, data, etc.) transmitted from the main control unit 10 after the initial setting process after turning on the power of the pachinko gaming machine 1. Determine whether or not. Specifically, the CPU core of the intermediate unit 20 writes the transmission data from the main control unit 10 into the reception data storage area of the RAM 20c via the data input / output unit (not shown) constituting the intermediate unit 20. It is determined whether or not. When the transmission data from the main control unit 10 is not written in the reception data storage area, the CPU core of the intermediate unit 20 ends the processing according to this flowchart.

On the other hand, when the transmission data from the main control unit 10 is written in the reception data storage area (step S201: YES), the CPU core of the intermediate unit 20 performs command analysis processing. Specifically, it is as follows.
In step S202, the CPU core of the intermediate unit 20 determines whether or not the data written in the received data storage area is a key command. Then, when the data written in the received data storage area is a key command (step S202: YES), the CPU core of the intermediate unit 20 starts the authentication process and is written in the received data storage area. If the data is not a key command (step S202: NO), the contents of the received data are further analyzed. Specifically, if the data written in the received data storage area is authentication data, it is stored in the authentication data storage area of the RAM 20c. On the other hand, if the data written in the received data storage area is data other than the authentication data, the process proceeds to step S203.

In step S <b> 203, the CPU core of the intermediate unit 20 transmits the data written in the received data storage area (data other than the key command and the authentication data) to the effect control unit 203 as it is. Specifically, the CPU core of the intermediate unit 20 writes the data written in the reception data storage area as it is in the transmission data storage area of the RAM 20c.
In step S204, the CPU core of the intermediate unit 20 immediately transmits the data written in the transmission data storage area to the effect control unit 203 as transmission data, and ends the processing according to this flowchart.

In step S205, when the data written in the reception data storage area is a key command (step S202: YES), the CPU core of the intermediate unit 20 uses the key command in the reception data storage area for the key data in the RAM 20c. Store in the storage area.
In step S206, the CPU core of the intermediate unit 20 confirms whether or not the authentication data received in advance is stored in the authentication data storage area. When the authentication data is not stored in the authentication data storage area (step S206: NO), the CPU core of the intermediate unit 20 ends the processing according to this flowchart, assuming that the authentication processing is not yet possible.

  In step S207, when the authentication data is stored in the authentication data storage area (step S206: YES), the intermediate CPU core obtains the key data and the authentication data from the key data storage area and the authentication data storage area. read out. When the key data and the authentication data are read from the key data storage area and the authentication data storage area, it is determined that the order written in both the storage areas matches the order read from both the storage areas ( The so-called first-in first-out rule (hereinafter referred to as a first-in first-out rule) matches the key data used for generating the authentication data and the key data constituting the key command more reliably. Therefore, it is possible to prevent the decryption process from being disabled due to a mismatch between the key data and the authentication data, and improve the accuracy of the authentication process.

In step S208, the CPU core of the intermediate unit 20 extracts a test value using the read key data and authentication data. Specifically, the CPU core of the intermediate unit 20 calculates the key data with respect to the authentication data by a preset decryption method.

  In step S210, the CPU core of the intermediate unit 20 reads the inspection value extracted from the inspection value storage area, and determines whether or not the inspection value matches the expected value. If the inspection value matches the expected value (step S210: YES), the CPU core of the intermediate unit 20 succeeds in individual authentication for the main control unit 10 in the current authentication process, and authenticates the normality of the pachinko gaming machine 1 The process proceeds to step S211. On the other hand, if the inspection value does not match the expected value (step S210: NO), the CPU core of the intermediate unit 20 has not succeeded in individual authentication for the main control unit 10 in the current authentication process, and the pachinko gaming machine 1 It is determined that there is a possibility that an illegal act or malfunction has occurred, and the routine proceeds to step 212.

In step S211, the CPU core of the intermediate unit 20 generates authentication result data indicating success, and proceeds to step S213.

In this process, the sub CPU core reads the 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 sub CPU core performs a process of initializing a flag and the like 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 S1300.

  In step S1100, the sub CPU core performs an effect random number update process. In this process, the sub CPU core performs a process of updating the effect random number value stored in the RAM 203c.

In step S1400, the sub CPU core performs update processing of various timer counters used in the effect control unit 203.

  In step S1500, the sub CPU core performs command analysis processing. In this process, the sub CPU core performs a process of analyzing the control command written in the received data storage area of the RAM 203c. When the production control unit 203 receives a control command transmitted from the main control unit 10 via the intermediate unit 20, a reception interruption process for the control command occurs, and the sub CPU core uses the received control command for the received data. Store in the storage area. Thereafter, the control command received in step S1500 is analyzed. Details of the command analysis process will be described later.

  In step S1600, the sub CPU core performs an authentication result data analysis process. In this process, the sub CPU core performs a process of analyzing the contents of the authentication result data when the various data written in the received data storage area of the RAM 203c is the authentication result data. In the effect control unit 203, when authentication result data is transmitted among various types of transmission data transmitted from the intermediate unit 20, authentication result data reception interruption processing occurs, and the sub CPU core receives the received authentication data. The result data is stored in the reception data storage area. Thereafter, the content of the authentication result data received in step S1600 is analyzed, and processing corresponding to the content indicated by the authentication result is executed. The details of the authentication result data analysis process will be described later.

In step S <b> 1700, the sub CPU core checks the signal of the effect button detection unit 220 and performs effect input control processing related to the effect button detection unit 220.
In step S1800, the sub CPU core performs a data transmission process of transmitting the control command and various data written in the transmission data storage area of the RAM 203c to the symbol display unit 104 and the lamp control unit 205.
In step S1900, the sub CPU core restores the information saved in step S1300 to the register of the CPU 203a.

FIG. 12 is a flowchart illustrating an example of a procedure of command analysis processing by the effect control unit 203.
In step S1501, the sub CPU core confirms whether or not the control command is written in the received data storage area, and confirms whether or not the control command is received. If the control command is not written in the reception data storage area, the sub CPU core ends the command analysis processing, and if the control command is written in the reception data storage area, the sub CPU core proceeds to step S1510.

In step S1510, the sub CPU core proceeds to step S1511 if the control command written in the received data storage area is the customer waiting demo command (see step S6 in FIG. 6), and if not, the sub CPU core is not the customer waiting demo command. The process proceeds to step S1520.
In step S1511, the sub CPU core performs a demonstration effect process for determining a demonstration 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. To send to.

In step S1520, the sub CPU core proceeds to step S1521 if the control command written in the storage area for received data is a symbol variation pattern command for jackpot or loss (see step S13 or step S19 in FIG. 6). If NO in step S1530, the flow advances to step S1530.
In step S1521, the sub CPU core 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 sub CPU core acquires one random number value from the effect random number value updated in step S1100 of FIG. 10, and the variable effect pattern determination table stored in advance in the acquired effect random value and the ROM 203b. Based on the above, one variation effect pattern is determined. Then, the sub CPU core writes an effect processing command based on the determined variation effect pattern in the transmission data storage area as transmission data, and transmits it to the symbol display unit 140 and the lamp control unit 205.

In step S1530, the sub CPU core proceeds to step S1531 if the control command written in the received data storage area is a symbol stop command (see step S15 or step S21 in FIG. 6), and must be a symbol stop command. If so, the process proceeds to step S1540.
In step S1531, the sub CPU core performs a symbol stop effect process for stopping and displaying the effect symbol indicating the variation mode. Specifically, the sub CPU core writes an effect processing command based on the symbol stop command in the transmission data storage area to transmit it to the symbol display unit 140 and the lamp control unit 205.

In step S1540, the sub CPU core proceeds to step S1541 if the control command written in the received data storage area is a jackpot start command (see step S16 in FIG. 6), and if not a jackpot start command, step S1550. Proceed to
In step S1541, the sub CPU core performs a jackpot start effect process for determining a jackpot start effect pattern. Specifically, the sub CPU core determines a jackpot start effect pattern based on the jackpot start command, writes an effect processing command based on the determined jackpot start effect pattern in the transmission data storage area as transmission data, and displays the symbol display. To the unit 140 and the lamp control unit 205.

In step S1550, the sub CPU core proceeds to step S1551 if the control command written in the received data storage area is a jackpot command (see step S17 in FIG. 6), and proceeds to step S1560 if it is not a jackpot command. .
In step S1551, the sub CPU core performs a jackpot presentation process corresponding to the round jackpot command. Specifically, the sub CPU core writes an effect processing command based on the jackpot command corresponding to each of the jackpot rounds to the transmission data storage area as transmission data, and transmits it to the symbol display section 140 and the lamp control section 205. .

In step S1560, the sub CPU core proceeds to step S1561 if the control command written in the received data storage area is the jackpot end command (see step S18 in FIG. 6), and if not the jackpot end command, this flowchart. The process by is terminated.
In step S1561, the sub CPU core performs a jackpot end effect process for determining a jackpot end effect pattern. Specifically, the sub CPU core determines a jackpot end effect pattern based on the jackpot end command, writes an effect processing command based on the determined jackpot end effect pattern in the transmission data storage area as transmission data, and displays the symbol display. The processing according to this flowchart is terminated.

FIG. 13 is a flowchart illustrating an example of a procedure of authentication result data analysis processing by the effect control unit 203.
In step S1601, the sub CPU core confirms whether or not the authentication result data is written in the reception data storage area, and confirms whether or not the authentication result data is received. If the authentication result data is not written in the reception data storage area, the sub CPU core ends the authentication result data analysis process. If the authentication result data is written in the reception data storage area, the sub CPU core proceeds to step S1610.

  In step 1610, the sub CPU core confirms whether or not the authentication result data written in the reception data storage area is a result indicating a successful authentication. When the authentication result data is a result indicating that the authentication is successful (step S1610: YES), the sub CPU core succeeds in the individual authentication for the main control unit 10 in the authentication process in the intermediate unit 20 this time, and the pachinko gaming machine 1 When it is determined that the normality can be authenticated, the processing according to this flowchart is terminated. On the other hand, if the authentication result data is a result indicating unsuccessful authentication (step S1610: NO), the sub CPU core has not succeeded in individual authentication for the main control unit 10 in the authentication process in the intermediate unit 20 this time, It is determined that there is a possibility that an illegal act or malfunction has occurred in the pachinko gaming machine 1, and the process proceeds to step S1620.

  In step 1620, if it is determined that there is a possibility that an illegal act or malfunction has occurred in the pachinko gaming machine 1 (step S1610: NO), the sub CPU core outputs a notification signal to notify that, The process according to the flowchart ends.

  The sub CPU core transmits the generated notification signal to, for example, the symbol display unit 104, the lamp control unit 205, or the 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 malfunction 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.

  The authentication process when the intermediate unit 20 is provided between the main control unit 10 and the prize ball control unit 204 is the authentication when the intermediate unit 20 is provided between the main control unit 10 and the effect control unit 203. Since the procedure is almost the same as the processing, the description is omitted.

  As described above, in the present embodiment, the encryption unit 530 configured by the encryption control circuit 10g (hardware) describes the authentication data necessary for individual authentication of the main control unit 10 in the program code. Regardless of an instruction from the main CPU core 500, it is generated in accordance with an algorithm that is uniquely stored and automatically transmitted to the intermediate unit 20. The key data necessary for decrypting the authentication data is output from the encryption control circuit 10 g only by a read instruction from the main CPU core 500 and immediately transmitted to the intermediate unit 20. Therefore, while having the authentication function for the main control unit 10, the processing load and program capacity of the CPU of the main control unit 10 that is increased by having the authentication function can be suppressed to the maximum, and the security of the pachinko gaming machine 1 Both improvement in strength and improvement in processing speed can be achieved.

  Further, in the present embodiment, control of processing relating to generation and transmission of authentication data may be defined by the algorithm of the encryption unit 530 itself. In addition, for the control of the processing related to the execution of the key command, a code corresponding to one type of control command (key command) may be added to the program code executed by the main CPU core 500. Specifically, it is only necessary to add a code relating to the key data reading instruction and a code relating to the writing of the key command, and it is sufficient to add only one instruction each in terms of the number of code steps. Therefore, the timing setting of authentication data and key command transmission, the update timing of key data, etc. can be designed freely, such as after a specific time or a specific number of clocks, and software control expandability and flexibility are also possible. The provided authentication function can be provided. In addition to this, since it is not necessary to perform a new timing design over the entire program code executed by the main CPU core 500, it is only necessary to design a timing by adding an authentication function. It can be carried out more easily and with less man-hours. This also increases the degree of freedom in design when adding an authentication function.

  In the present embodiment, the intermediate unit 20 executes most of the authentication process such as the authentication data decryption process and the verification value and expected value matching process. Therefore, the production control unit 203 executes the authentication process only when the authentication result data is received from the intermediate unit 20. In other words, the processing load on the CPU of the effect control unit 203 increases only when the authentication result data is received by performing the authentication process, so that the rate of increase in the processing load of the effect control unit 203 can be suppressed. it can. Further, it is only necessary to add a program code related to the authentication result data analysis process to the program code executed by the effect control unit 203. Accordingly, since it is not necessary to perform new timing design over the entire program code executed by the production control unit 203, timing design can be performed simply by adding an analysis function of authentication result data, and function implementation, function verification, etc. It can be carried out more easily and with less work man-hours. This also increases the degree of design freedom when adding functions related to authentication processing.

  In the present embodiment, the transmission timing of the key command is set based on the power-on command, and the authentication process of the pachinko gaming machine 1 is started when the power is turned on. In this case, the power-on command is transmitted when the pachinko gaming machine 1 is initialized (after the initial setting process), such as when the pachinko gaming machine 1 is powered on or reset. The initialization process of the pachinko gaming machine 1 is classified into a process category different from the game (game progress) related process which is the main process of the pachinko gaming machine 1. Therefore, if the authentication process is incorporated during the initialization process of the pachinko gaming machine 1 as in the present invention, the steps (man-hours) required for the program design and testing are compared with the case where the authentication process is incorporated during the game related process. The rate of increase can be reduced. That is, by incorporating the authentication process during the initialization process of the pachinko gaming machine 1, it is possible to obtain a merit in reducing development costs and quality control. In addition, if the authentication process is incorporated during the initialization process of the pachinko gaming machine 1, the authentication process is performed immediately after the pachinko gaming machine 1 is activated, so that even if the fraud is performed after the game store is closed, It is possible to detect fraud before the customer enters the store. Therefore, the risk of damage caused by fraud can be reduced.

  Further, when the transmission timing of the key command is set based on the customer waiting demo command and the authentication process of the pachinko gaming machine 1 is started at the customer waiting demo, the customer waiting demo command indicates that the pachinko gaming machine 1 is in a non-game state, That is, since it is transmitted when the game (game progress) related process which is the main process of the pachinko gaming machine 1 is not performed, an increase in processing load due to the authentication process does not affect the game related process. For this reason, even when the main control unit 10 and the peripheral unit 30 do not have a high processing capacity, or even in the pachinko gaming machine 1 with a large processing load of game-related processing, an authentication processing function can be added. . Further, since the customer waiting demo command is a command issued before the customer operates the pachinko gaming machine 1, it is possible to detect fraud before the customer operates the pachinko gaming machine 1.

  Further, in the present embodiment, at the time of authentication processing in the intermediate unit 20, the transmission of authentication data and the transmission of the key command are 1 so that the types of key data constituting the key command and the authentication data do not match. The update timing of the key data is set so that the authentication data is generated with new key data every time it is completed. However, the present invention is not limited to this, and the key data may be updated after the authentication data is transmitted a plurality of times while the transmission of one key command is completed. In this case, the number of authentication data transmissions before the key data is updated may be kept below the number of authentication data that can be held in the authentication data storage area of the intermediate unit 20. At this time, if the first-in first-out rule at the time of the decryption process is observed, the intermediate unit 20 is limited to performing the decryption process on the authentication data received immediately before receiving the key command as in the present embodiment. For example, the decryption process can be performed on the authentication data received a predetermined number of times before the key command is received. Further, the information indicating the predetermined number of times and the information indicating the update status of the key data may be transmitted together with the key data.

  In the present embodiment, the main control unit 10 transmits the key command after transmitting the authentication data first. However, the present invention is not limited to this, and the authentication is performed after the key command is transmitted first. Data may be transmitted. At this time, in the intermediate unit 20, the authentication data to be decrypted when the key command is received is authentication data received immediately after the key command is received. You just have to decide on first-in first-out rules. Further, the authentication processing trigger in the intermediate unit 20 may be configured to receive authentication data instead of receiving a key command.

  In the present embodiment, the transmission unit 520 constituting the main control unit 10 immediately transmits the data received from each component to the intermediate unit 20, but the present invention is not limited to this, The received data may be temporarily stored in the transmission unit 520, and the transmission unit 520 may be configured to measure the transmission timing to the intermediate unit 20. The same applies to transmission of control commands and authentication result data from the intermediate unit 20 to the effect control unit 203, and data written in the transmission data storage area of the RAM 20c is transmitted to the effect control unit 203 as transmission data. When transmitting, the transmission unit (not shown) constituting the intermediate unit 20 can temporarily store the transmission data, and the transmission unit can measure the transmission timing to the effect control unit 203. Good.

  In the present embodiment, the main control unit 10 encrypts the inspection value to generate authentication data and transmits it to the intermediate unit 20, and the intermediate unit 20 decrypts the authentication value to extract the inspection value and authenticates it. Processing is in progress. Then, the intermediate unit 20 transmits the obtained authentication result to the effect control unit 203 as authentication result data without performing any particular encryption process. However, the present invention is not limited to this. For example, the authentication data may be transmitted to the intermediate unit 20 as authentication data without performing encryption processing on the inspection value. Further, the authentication result data may be transmitted to the effect control unit 203 as authentication result data obtained by performing encryption processing on the obtained authentication result. When both the authentication data and the authentication result data are encrypted, the intermediate unit 20 encrypts the key data used for the decryption process of the received authentication data and the generated authentication result data. What is necessary is just to use the same key data used for the digitization process. In other words, the intermediate unit 20 decrypts the authentication data using the key data constituting the key command transmitted from the main control unit 10, and then performs an encryption process on the obtained authentication result with the key data. Authentication result data may be generated.

  In such a case, in the present embodiment, since the intermediate unit 20 is provided between the main control unit 10 and the effect control unit 203, the CPU 10a and the effect control unit 203 constituting the main control unit 10 are configured. The intermediate unit 20 absorbs the processing capacity difference between the CPU 203 a and the storage capacity difference between the ROM 10 b or RAM 10 c constituting the main control unit 10 and the ROM 203 b or RAM 203 c constituting the effect control unit 203. Can do. Thereby, even when there is a difference in processing capacity and storage capacity between the main control unit 10 and the effect control unit 203, the security strength between the main control unit 10 and the effect control unit 203 can be maintained.

  That is, for example, the processing capacity of the CPU 10 a constituting the main control unit 10 and the storage capacity of the ROM 10 b and the RAM 10 c constituting the main control unit 10 constitute the processing capacity of the CPU 203 a constituting the effect control unit 203 and the effect control unit 203. When there is a margin in comparison with the storage capacity of the ROM 203b or the RAM 203c, the main control unit 10 performs complex encryption processing on the inspection value, generates authentication data, and transmits the authentication data to the intermediate unit 20. The intermediate unit 20 performs an authentication process using the received authentication data, performs a relatively simple encryption process on the obtained authentication result (or the authentication result itself), generates authentication result data, and effects control To the unit 203. The effect control unit 203 can perform the authentication process by performing a relatively simple decryption process on the received authentication result data (or the authentication result data itself). With this configuration, the pachinko gaming machine 1 can maintain a high level of security without adopting a complicated decoding method in the effect control unit 203.

  Further, for example, the processing capacity of the CPU 203 a configuring the effect control unit 203 and the storage capacity of the ROM 203 b and the RAM 203 b configuring the effect control unit 203 configure the processing capability of the CPU 10 a configuring the main control unit 10 and the main control unit 10. When there is a margin in comparison with the storage capacity of the ROM 10b or RAM 10c, the main control unit 10 performs a relatively simple encryption process on the inspection value (or with the inspection value itself) to generate authentication data and generate an intermediate unit 20 is transmitted. The intermediate unit 20 performs authentication processing using the received authentication data, performs complex encryption processing on the obtained authentication result, generates authentication result data, and transmits the authentication result data to the effect control unit 203. The effect control unit 203 performs an authentication process by performing a complex decryption process on the received authentication result data. With this configuration, the pachinko gaming machine 1 can maintain a high level of security without adopting a complicated encryption method in the main control unit 10.

Further, in the pachinko gaming machine 1 according to the present embodiment, the intermediate unit 20 is configured to include a CPU, a ROM, a RAM, and the like, but the same function is configured to be realized as an integrated circuit such as an LSI. Also good.
In this embodiment, an example in which the present invention is applied to a pachinko gaming machine has been shown. The present invention can also be applied to other game machines such as a spinning machine such as a machine or a slot machine. Even in these gaming machines, the same effects as in the present embodiment can be obtained by configuring in the same manner as in the present embodiment. Moreover, this embodiment can divert each other's technology as long as there is no particular contradiction or problem in its purpose and configuration.
