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 part that controls the lamp, the speaker, etc. performs a predetermined calculation using the first identification information, the second identification information, and the third identification information to control the display. The CPU mounted on the second peripheral portion 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, a great deal of time and effort is spent on the design of the authentication timing for adding the authentication function, the realization of the authentication function, the simulation of the operation, and the verification (verification) to confirm whether the desired function can be obtained. Therefore, there is a problem that it takes a lot of time and effort to develop a gaming machine. Such a problem particularly appears when changing the model of a 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 performs authentication processing in addition to the existing processing, the processing load of the CPU increases, so the processing speed decreases, display for production is not performed smoothly, or in the worst case There was a problem that the authentication process itself could not be added. In particular, in recent years, in order to improve the interest of the game, there is a tendency that the effects of appealing to the visual and auditory senses of the player at the time of reach, jackpot, etc. tend to be diverse, and the possibility that the above problem 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 peripheral portion to execute the authentication process in addition to the existing processing, the processing load of the CPU configuring the peripheral portion increases. Therefore, it is difficult to cause the CPU configuring the peripheral portion to execute authentication processing by a more complicated calculation and authentication processing multiple times than ever in order to further enhance security.

  On the other hand, in the second conventional example, in the main control unit, the encryption unit performs encryption corresponding to the first key data on the control data for controlling the operation of the symbol control unit, and the first key change unit The first key data is changed at a predetermined timing. In the peripheral unit, the authenticating unit performs processing corresponding to the second key data on the encrypted data received from the main control unit, thereby determining the validity of the received encrypted data. Authentication is performed, and the second key data is changed to correspond to the first key data at a predetermined timing so that the second key changing means matches 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 it is transmitted to the part, the processing load on the CPU in the peripheral part increases, so the processing speed decreases, the display for presentation is not performed smoothly, or it is difficult to add the authentication process itself It is conceivable that there will be restrictions. In recent years, in particular, in order to improve the interest of the game, there is a tendency for various effects to appeal to the visual and auditory sense of the player regarding the control of the variation of the pattern. Therefore, it is desirable to construct a gaming machine provided with an authentication unit that reduces the load of performing an authentication process on a peripheral part (image control part) that performs various effects control.

  Further, by causing the CPU constituting the peripheral portion to execute the authentication process in addition to the existing processing, the processing load and program capacity of the CPU constituting the peripheral portion are increased. Therefore, it is difficult to cause the CPU configuring the peripheral portion to execute authentication processing by a more complicated calculation and authentication processing multiple times than ever in order to further enhance security.

  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. In this case, if a bit error occurs and the control command is changed to a jackpot command even though the control command that should be transmitted to the peripheral part is a control command other than the jackpot command, an illegal action is performed. Even if this is not the case, an unreasonable amount of game media is paid out to the player, and the game store suffers a great deal of damage. However, in the first to third conventional examples, no countermeasures are taken for the problem caused by such a malfunction, so that the problem that the game shop suffers a great deal of damage cannot be solved.

Specifically, the operation inspection value is, for example, a number (hereinafter referred to as a function number) assigned in advance for each process for executing a predetermined function in a program executed by the main control unit 10 or a main number. It is a value that fluctuates according to a predetermined rule in processing performed by the main control unit 10 such as the number of times authentication processing is executed in the control unit 10 (hereinafter referred to as the number of authentications). The operation inspection value generation unit 14 switches the type of operation inspection value used for the next authentication process based on the number of divisions.

  Thereafter, the main control unit 10 performs encryption processing on each of the individual authentication data for the number of divisions obtained by performing encryption processing on the individual inspection values for the generated number of divisions and the generated operation inspection value. The operation authentication data obtained by the application is added to the control command to be output and transmitted to the intermediate unit 20. The individual authentication data includes data obtained by performing a predetermined calculation on the individual test value and the individual test value itself, and the same applies to the operation authentication data. In the first embodiment, it is assumed that the individual authentication data is obtained by performing encryption processing on the individual inspection value, and the operation authentication data is obtained by performing encryption processing on the operation inspection value.

  On the other hand, the intermediate unit 20 includes an expected value storage unit 21 and an intermediate authentication unit 22. The expected value storage unit 21 stores an expected value of the operation test value generated by the operation test value generation unit 14 constituting the main control unit 10 (hereinafter, referred to as an intermediate operation authentication expected value). In the first embodiment, the intermediate operation authentication expected value is a function number authentication expected value corresponding to an operation inspection value that is a function number. In addition, the expected value storage unit 21 stores the number of authentications, which is the number of times the intermediate unit 20 has performed the authentication process, in order to collate with the operation inspection value generated by the operation inspection value generation unit 14. The intermediate authentication unit 22 uses the individual authentication data transmitted from the main control unit 10 and the result of the intermediate operation authentication using the operation authentication data, and finally performs the final authentication from both sides of the individual authentication and the operation authentication in the peripheral unit 30. Intermediate authentication information to be used when making an authentication decision is generated.

  Specifically, the intermediate authentication unit 22 first performs intermediate operation authentication on the processing operation of the main control unit 10 using the operation authentication data transmitted from the main control unit 10. In the intermediate operation authentication, an operation inspection value is extracted from the operation authentication data transmitted from the main control unit 10, and it is verified whether the extracted operation inspection value is the same as the number of times of authentication stored in the expected value storage means 21. If they are not the same, it is further verified whether or not the expected function number authentication value stored in the expected value storage means 21 is the same. The intermediate unit 20 holds, as an intermediate operation authentication result, information on whether or not the two are the same obtained by collating with the expected function number authentication value. The intermediate authentication unit 22 generates an intermediate operation authentication result indicating non-identity when the operation inspection value and the number of authentications are the same.

  Thereafter, the intermediate unit 20 combines the intermediate operation authentication result and the individual authentication data transmitted from the main control unit 10 as intermediate authentication information, adds it to the control command, and transmits it to the peripheral unit 30.

  The peripheral unit 30 includes an expected value storage unit 31 and an authentication unit 32. The expected value storage means 31 uses an expected value (hereinafter referred to as an individual authentication expected value) obtained by performing a binary operation using predetermined data stored in the data storage means 11 constituting the main control unit 10. In advance). In addition, the expected value storage means 31 uses the expected value (hereinafter referred to as the operation) to predict whether the current intermediate operation authentication result transmitted from the intermediate unit 20 indicates the same or non-identical. It is stored as an authentication expected value). The authentication unit 32 performs individual authentication using the individual authentication data included in the intermediate authentication information transmitted from the intermediate unit 20, and performs operation authentication using the intermediate operation authentication result included in the intermediate authentication information. And the normality of the pachinko gaming machine 1 is authenticated from the result of both authentication processing (hereinafter referred to as authentication processing).

  Specifically, the authentication unit 32 first performs individual authentication using the individual authentication data transmitted from the intermediate unit 20. More specifically, the authentication unit 32 extracts the individual test value from the individual authentication data included in the intermediate authentication information added to the control command and transmitted from the intermediate unit 20, and the above-described individual test value is extracted with respect to the extracted individual test value. Whether or not the individual authentication is successful is determined based on whether or not the calculation result obtained by performing the binary operation satisfying the coupling rule matches the individual expected value stored in the expected value storage unit 31.

  Next, the authentication unit 32 performs operation authentication using the intermediate operation authentication result transmitted from the intermediate unit 20 and the number of individual test values when individual authentication is successful (hereinafter referred to as the number of connections). More specifically, the authentication unit 32 includes the intermediate operation authentication result (indicating the same or non-identity) transmitted from the intermediate unit 20 and the current operation authentication expected value (currently stored in the expected value storage unit 31). In the process related to authentication, the operation test value transmitted from the main control unit 10 to the intermediate unit 20 is predicted to determine whether the function number authentication expected value held by the intermediate unit 20 is the same, Whether or not the operation authentication is successful is determined based on whether or not the two match. Further, the authentication means 32 is either the same or non-identical operation authentication expected value used for the process related to the next authentication based on the number of individual test values (number of connections) when the individual authentication by the authentication means 32 is successful. Select.

  After that, the peripheral unit 30 authenticates the normality of the pachinko gaming machine 1 when both the individual authentication and the operation authentication of the authentication unit 32 are successful, and performs processing according to the authentication result.

  In addition to the basic operation control related to the game of the pachinko gaming machine 1 as outlined above, the main control unit 10 is a process related to authentication of the main control unit 10 for preventing fraud, which is a feature of the first embodiment. Means for executing. The means for executing the processing relating to the authentication is realized by the CPU 10a executing a program (program code) stored in advance in the ROM 10b. The processing related to this authentication is as described in [1] to [5] below, but the encryption processing shown in [3] is executed as necessary.

[1] Determination of the number of divisions The main control unit 10 determines the number of divisions, which is a number for dividing predetermined data stored in advance in the ROM 10b, for example, predetermined program codes (instruction codes and fixed data). Hereinafter, as an example of the predetermined data, description will be given using a predetermined program code. The main control unit 10 uses, for example, a value generated by a random number generation circuit (not shown) or a random number generation program constituting the program code as a division number, or a value generated in other processing of the main control unit 10. The value can be referred to at a predetermined timing and the value can be used as the division number. In this case, the upper limit of the number of divisions may be set in advance. The means for executing the process for determining the number of divisions can correspond to, for example, the determination means 12 shown in FIG. In the first embodiment, the main control unit 10 determines the number of divisions using random numbers, but this is an example for determining the number of divisions, and determines the number of divisions without using random numbers. You may make it do. For example, the main control unit 10 holds a table for determining the number of divisions in advance, and the main control unit 10 obtains the number of divisions from the table according to a predetermined rule at the timing of determining the number of divisions. You may do it.

[2] Generation of Individual Examination Value Next, the main control unit 10 divides the storage area in which a predetermined program code in the ROM 10b is stored in advance by the number of divisions determined in the process [1]. Then, the main control unit 10 performs a binary operation on the program code stored in each divided storage area of the ROM 10b, and the individual test values for the number of divisions for individual authentication of the main control unit 10 Is generated. Note that the same method is used in advance between the main control unit 10 and the effect control unit 203 for the individual test value generation method (for example, the type of binary operation that satisfies the combination rule used for generating the individual test value). Just set it up.

“Binary operation satisfying the join rule” means that among the binary operations that perform operations between two terms, if the operator is § and any number is a, b, c, formula (1) holds Binary operation.
(A§b) §c = a§ (b§c) = a§b§c (1)
In other words, “binary operation satisfying the combination rule” is a case where the operation objects a, b, and c are divided as operation objects to be subjected to binary operation at a time and are operated by the operator §. Is also a binary operation in which the obtained calculation results have the same value. However, an operator ♪ in which the operation result of a ♪ b is always 0 for any number a and b is excluded from the operator §. Since a defined set of binary operations that satisfy the above-mentioned combination rule is generally called a semigroup, such a binary operation is hereinafter referred to as a semigroup operation. Examples of the semi-group operation include addition, multiplication, and exclusive OR.

Hereafter, two simple specific examples of the semigroup operation will be given.
First, each data constituting each data block obtained by dividing a predetermined program code is defined as D0, D1, D2,..., DN (N is the final address of each data block).
(A) If addition (operator +) is selected as the semi-group operation, equation (2) is calculated.
D0 + D1 + D2 + ... + DN (2)
(B) When an exclusive OR (operator XOR) is selected as the semi-group operation, Equation (3) is calculated.
D0 XOR D1 XOR D2 XOR ... DN (3)

A method for generating each individual test value will be described with reference to FIG.
FIG. 4 is an explanatory diagram schematically showing a method for generating an individual test value in the main control unit 10. The individual test value is generated by the main control unit 10 using predetermined data stored in advance in the ROM 10b. More specifically, the main control unit 10 divides a predetermined storage area of the ROM 10b by an arbitrary number of divisions, and then performs a binary operation that satisfies the combining law for each program code stored in the divided storage area ( An individual test value is calculated by performing a semi-group operation. Examples of the semi-group operation include addition, multiplication and exclusive OR operation as described above.

(Example of individual test value generation calculation)
An example of calculation of individual test value generation is shown below.
In the program code storage area 400 shown in FIG. 4, 12 program codes (“0x01” to “0x09”, “0x0A” to “0x0C”) are stored. When the division number is 3, the program code storage area 400 is, for example, a first block 400a including four program codes, a second block 400b including three program codes, and a third block including five program codes. It can be divided into blocks 400c. The main control unit 10 performs a semigroup operation on the program code stored in each of these blocks to calculate an individual test value. The number of program codes in the block is an example. The number of program codes in the divided block may be a fixed value or may be determined randomly.

  For example, if the method using the addition of Expression (2) as the semi-group operation is Method A, the four program codes “0x01”, “0x02”, “0x03”, “0x04” stored in the first block 400a are used. The first individual test value “0x0A” is obtained by addition. Similarly, three program codes “0x05”, “0x06”, “0x07” stored in the second block 400b are added, and the second individual test value “0x12” is stored in the third block 400c. The third individual test value “0x32” is obtained by adding the program codes “0x08”, “0x09”, “0x0A”, “0x0B”, “0x0C”.

  Further, for example, if the method using the exclusive OR operation of Expression (3) as the semi-group operation is method B, the four program codes “0x01”, “0x02”, “0x03” stored in the first block 400a are used. ”And“ 0x04 ”to perform an exclusive OR operation to obtain a first individual test value“ 0x04 ”. Similarly, exclusive OR operation is performed on the three program codes “0x05”, “0x06”, and “0x07” stored in the second block 400b, and the second individual test value “0x04” is stored in the third block 400c. A third individual test value “0x0C” is obtained by performing an exclusive OR operation on the five stored program codes “0x08”, “0x09”, “0x0A”, “0x0B”, and “0x0C”.

In the first embodiment, as will be described later, the main control unit 10 generates data for authenticating the normality of the pachinko gaming machine 1, and adds the generated data to the control command to add the intermediate unit 20 or the effect. It transmits to the control part 203. Here, data for authenticating the authenticity of the main control unit 10 added to the control command is collectively referred to as “individual authentication data”. The individual authentication data is data obtained by performing encryption processing on each individual test value or these individual test values. Further, data for authenticating the continuity of the operation of the pachinko gaming machine 1 added to the control command will be collectively referred to as “operation authentication data”. The operation authentication data is data obtained by performing encryption processing on each operation inspection value or these operation inspection values. Hereinafter, in the first embodiment, the individual authentication data or the operation authentication data will be described as data obtained by performing encryption processing on the individual inspection value or the operation inspection value, but the present invention is not limited to this, Processing related to authentication may be performed using the individual test value or the operation test value itself as the individual authentication data or the operation authentication data. In this case, it is not necessary to perform encryption processing on the individual test value or the operation test value in the main control unit 10, and when the individual test value or the operation test value is extracted in the intermediate unit 20 or the effect control unit 203, the individual authentication data or Since it is not necessary to decrypt the operation authentication data, it is possible to simplify the process related to authentication and suppress an increase in processing load.
The means for executing the process for generating the individual test value can correspond to, for example, the individual test value generation means 13 shown in FIG.

[3] Generation of Individual Authentication Data The main control unit 10 performs an encryption process on each individual test value generated in the process [2] and adds an individual to the control command (control command data and accompanying data). Generate authentication data. Here, as an encryption method, for example, a relatively simple method such as Caesar encryption, single substitution encryption, or enigma can be employed. The same applies to the encryption method used below. Caesar encryption is an encryption method in which characters constituting a message (plain text) are encrypted by shifting by a certain number of characters. Single substitution cryptography is an encryption scheme that encrypts characters by converting the characters constituting the plaintext into other characters. Enigma is set with Enigma using key encryption key, Encrypt communication key with Enigma, Enigma Enigma with communication key, plaintext encryption, encrypted communication key and encrypted This is an encryption method through a process of generating a communication text by combining plaintext.

  In the main control unit 10, when each individual authentication data obtained by performing encryption processing on each individual test value is transmitted to the intermediate unit 20, each individual test value that has not been subjected to any processing is used as it is. Compared with the case of transmitting to the intermediate unit 20, it is possible to reduce the possibility that each individual test value is analyzed by an unauthorized person. The main control unit 10 may perform different encryption processing for each individual test value.

  A predetermined processing process may be further added to the encryption process. As the predetermined processing, for example, a process of obtaining arithmetic data having a predetermined data length by performing four arithmetic operations or logical operations using the individual test values subjected to encryption processing, these four arithmetic operations or logical Extracting a plurality of bits constituting each individual test value subjected to processing for rearranging the bit arrangement of operation data obtained by operation, processing for shifting or rotating the bits of operation data, and encryption processing For example, a process of generating one piece of data arranged in accordance with a predetermined rule can be considered.

(Calculation example for generating individual authentication data)
An example of calculation for generating individual authentication data is shown below.
An example of generating individual authentication data from the first individual test value “0x0A” shown in FIG. 4 will be described. As the encryption process, a process of adding control command data to the individual test value and then subtracting “0x03” from the obtained data is employed. The main control unit 10 performs the above-described encryption processing on the first individual test value to generate individual authentication data.

The values of the control command data and the accompanying data to which the individual authentication data is added are assumed to be “0xEE” and “0x01”. In the encryption process, since the value “0xEE” of the control command data is added to the first individual inspection value “0x0A”, “0xF8” is obtained. Next, by subtracting “0x03” from this “0xF8”, the value “0xF5” of the individual authentication data is obtained.
Similarly, when individual authentication data is generated from the second individual test value “0x12” recorded in the program code storage area 400 shown in FIG. Is generated, the value becomes “0x1D”.

  Note that the individual authentication data may be generated by performing an encryption process on the data including the individual test value and the control command data transmitted along with the individual authentication data or at least one of the accompanying data. The individual authentication data may include control command data transmitted along with the individual authentication data and data related to the accompanying data. Data related to control command data and accompanying data is the above processing, control using a hash function, parity check, cyclic redundancy check (CRC), checksum, etc. for control command data and accompanying data. It is the value obtained by going.

  By generating the individual authentication data using the control command data and accompanying data transmitted together with the individual authentication data, even if the individual authentication data is reused by an unauthorized control unit, the individual authentication data and the control command Mismatch is not possible and fraud can be detected. Further, even if the control command data is changed due to a malfunction, since the authentication is not successful, execution of the control command corresponding to the control command data changed due to the noise or the like can be prevented.

  When the individual authentication data includes data related to control command data and accompanying data, the main control unit 10 performs encryption processing by combining the data related to the control command data and accompanying data and the individual test value, and the individual authentication data. You may perform the process which produces | generates.

  The timing at which the main control unit 10 generates each individual test value and the timing at which individual authentication data is generated using each individual test value are not particularly limited, and in the control program of the main control unit 10, What is necessary is just to incorporate the program which performs the process which produces | generates each individual test value, and the process which produces | generates individual authentication data using each individual test value.

[4] Generation of Operation Inspection Value The main control unit 10 adds the control command data and the accompanying data to the intermediate unit in order to authenticate the continuity of the operation of the pachinko gaming machine 1 in the intermediate unit 20 and the effect control unit 203. An operation inspection value to be transmitted to the CPU 20 is generated and stored in an operation inspection value memory which is a predetermined storage area of the RAM 10c. The operation inspection value is generated by using a value that fluctuates according to a predetermined rule in the process continuously performed by the main control unit 10 such as a function number and the number of times of authentication.

  Hereinafter, a case where an operation inspection value is generated using a function number will be described. In the main control unit 10, function numbers are assigned in advance without duplication for each process for executing a predetermined function in various programs to be executed (for example, jackpot commands). When the main control unit 10 executes the program to which the function number is assigned, the main control unit 10 acquires the function number every time a predetermined function is executed. The main control unit 10 stores the acquired function number as an operation inspection value in an operation inspection value memory, which is a predetermined storage area of the RAM 10c, in a state where the acquired order can be determined. For example, the main control unit 10 stores a plurality of acquired function numbers (operation inspection values) in the order of acquisition. The plurality of operation inspection values arranged and stored in the acquired order indicate the operation order when the main control unit 10 executes various programs.

  A specific example of how to assign function numbers will be described. The function number can be assigned to control commands generated in succession such as a jackpot reach command, a jackpot start command, and a subsequent jackpot command (for example, for 15 rounds). In this case, function number 1 is assigned to the jackpot reach command. Next, function number 2 is assigned to the jackpot start command. Next, function numbers 3 to 17 are assigned to the respective commands of the 15-round jackpot command. In this way, continuity of the operation sequence of the main control unit 10 is obtained by assigning consecutive function numbers to the control commands that are generated continuously in time series, and checking the continuity of the function numbers that are continuously generated, The continuity of the operation of the main control unit 10 can be authenticated. The function number may be assigned for each predetermined function of a program that is continuously executed, and the granularity of the predetermined function of the program is not particularly limited.

  Hereinafter, a case where an operation inspection value is generated using the number of times of authentication will be described. The number of times of authentication is the total number of times a series of authentication-related processes performed between the main control unit 10, the intermediate unit 20, and the effect control unit 203 since the power of the pachinko gaming machine 1 is turned on. . In one operation authentication process, the operation authentication data generation process in the main control unit 10 is executed once, and the intermediate operation authentication in the intermediate unit 20 and the operation authentication in the effect control unit 203 are also executed once. Therefore, the number of execution times of the operation authentication data generation process and the number of execution times of the intermediate operation authentication and the operation authentication process are the same value. In other words, the number of times of authentication is the number of times that the operation control data generated by the main control unit 10 is acquired and operation authentication data is generated, and is the number of times that the operation control unit 203 has successfully performed the operation authentication. The main control unit 10 stores the number of times of authentication as an operation inspection value in an operation inspection value memory which is a predetermined storage area of the RAM 10c. The main control unit 10 adds 1 to the value of the number of authentications stored in the RAM 10c every time the authentication process is performed, generates a new value of the number of authentications, that is, a new operation inspection value, and stores the operation inspection value in the RAM 10c. To remember.

  In addition, the number of authentications may be the number of executions of individual test value generation processing and individual authentication processing. In this case, for example, the effect control unit 203 may notify the intermediate unit 20 of the number of executions of individual authentication in the effect control unit 203 and cause the intermediate unit 20 to recognize the number of executions of individual authentication as the number of authentications. When the number of executions of the individual test value generation process and the number of executions of the operation authentication data generation process are different from the number of executions of the individual authentication process and the number of executions of the operation authentication process (including the intermediate operation authentication process) Even so, if the correspondence relationship is clarified, the number of executions of the individual test value generation process and the individual authentication process can be defined as the number of authentications used for the operation code.

  The means for executing the process for generating the operation inspection value can correspond to, for example, the operation inspection value generation means 14 shown in FIG.

[5] Generation of Operation Authentication Data The main control unit 10 may perform an encryption process on the operation check value generated in the process [4]. Here, as the encryption method, the same method as that used when generating the individual authentication data can be considered. The encryption process performed when generating the individual authentication data and the encryption process performed when generating the operation authentication data may be the same encryption process or different encryption processes. Different encryption processing may be performed for each operation inspection value.

  When the operation check value subjected to the encryption process in the main control unit 10 is transmitted to the intermediate unit 20, compared to the case where the operation check value that has not been subjected to any processing is transmitted to the intermediate unit 20 as it is, It is possible to reduce the possibility that the behavior inspection value is analyzed by an unauthorized person. Note that a predetermined processing process may be further added to the encryption process as in the case of generating the individual authentication data. About these encryption processes in general, the same applies to data and information generation processing related to authentication in the intermediate unit 20 and the effect control unit 203, such as generation of intermediate authentication information 305 in the intermediate unit 20 described later.

  Specifically, when generating the operation authentication data using the function number as the operation inspection value, when the operation authentication data generation timing comes, the main control unit 10 stores the operation stored in the operation inspection value memory of the RAM 10c. An inspection value is acquired, and encryption processing is performed on it to generate operation authentication data. When the main control unit 10 generates a plurality of operation test values using the function number, the operation authentication data is retained while maintaining the order in which the plurality of operation test values are generated, that is, the operation order of the main control unit 10. Is generated. For example, the main control unit 10 generates operation authentication data by performing encryption processing on each of the operation test values while holding an array of a plurality of function numbers (operation test values) arranged in the acquired order. Therefore, the operation authentication data includes information on the operation sequence when the main control unit 10 executes various programs, similarly to the array of the plurality of operation inspection values arranged.

  Further, when generating the operation authentication data using the number of times of authentication as the operation inspection value, the main control unit 10 determines the operation inspection value (stored in the operation inspection value memory in the RAM 10c) at the generation timing of the operation authentication data. The number of times of authentication) is acquired, and encryption processing is performed to generate operation authentication data.

  Further, the main control unit 10 switches the operation authentication data generation method, that is, the type of operation inspection value used when generating operation authentication data to be transmitted to the intermediate unit, according to a predetermined agreement based on the number of divisions. For example, when the number of divisions this time is an odd number, the main control unit 10 selects a type of operation inspection value that is different from the operation inspection value used this time as the operation inspection value used for generating the next operation authentication data, When the current division number is an even number, the same type of operation inspection value as the current operation inspection value is selected as the operation inspection value used for generating the next operation authentication data. It should be noted that the type of motion inspection value used for generating the motion authentication data for the first time is set in advance to use the same method between the main control unit 10, the intermediate unit 20, and the effect control unit 203.

  The main control unit 10 selects which type of operation inspection value to be used for generating the operation authentication data based on the value of the number of divisions known only to the main control unit 10, so that any type of operation authentication data can be generated by the fraudster. It is possible to prevent the user from knowing whether the operation test value is used. Thereby, it is possible to prevent the operation authentication data from being illegally generated. Hereinafter, in the first embodiment, as a predetermined agreement, when the division number is an odd number, the type of the operation inspection value used for generating the operation authentication data is changed, and when the division number is an even number, the type of the currently used type is changed. It is assumed that the method of continuing the operation test value is adopted, and the type of the first operation test value is the function number.

  Here, the operation authentication data may be generated by performing encryption processing on the data including the control command data transmitted along with the operation authentication data or at least one of the accompanying data and the operation inspection value. Further, the operation authentication data may include control command data and accompanying data transmitted together with these.

  Note that the main control unit 10 may determine in advance between the main control unit 10, the intermediate unit 20, and the effect control unit 203 regarding the decoding process and the like. For example, when the main control unit 10 performs the encryption process on the operation inspection value using the first encryption method and generates the operation authentication data, the intermediate unit 20 uses the decryption method corresponding to the first encryption method. The decryption process is performed, the operation check value is extracted, and the process related to authentication is performed. Thereafter, the intermediate unit 20 performs an encryption process on the obtained result using the second encryption method, and generates intermediate authentication information to be described later. The effect control unit 203 performs a decryption process using a decryption method corresponding to the second encryption method, extracts a result obtained by the intermediate unit 20, and performs a process related to authentication. This is not limited to the generation of operation authentication data and the extraction of operation inspection values, and the same applies to the generation of individual authentication data and the extraction of individual inspection values.

In addition, the main control unit 10 prepares a plurality of methods such as encryption processing used for generating individual authentication data or operation authentication data in advance, and determines the number of current divisions (data block of the data block) determined in the process [1]. Based on the number, one encryption process used for generating the next operation authentication data may be selected from a plurality of encryption processes. Specifically, for example, when the current number of divisions is an odd number, the main control unit 10 selects the next encryption process different from the encryption process used this time, and when the current number of divisions is an even number, The next encryption process is the same as the encryption process used this time. At this time, the selection method of the method such as the decryption process is the same as that of the method such as the encryption process. What is necessary is just to decide in advance between the main control unit 10, the intermediate unit 20, and the effect control unit 203 so as to select a decryption method corresponding to the encryption method used.
It should be noted that these encryption processes in general also apply to authentication-related data and information signal generation processing in the intermediate unit 20 and the effect control unit 203, such as generation of intermediate authentication information in the intermediate unit 20 described later. .

[6] Data addition to control signal The main control unit 10 adds individual authentication data and operation authentication data to the control command data and accompanying data transmitted to the effect control unit 203 via the intermediate unit 20 to generate authentication data. A control signal is generated. Hereinafter, the individual authentication data and the operation authentication data are also referred to as authentication data.

[7] Transmission of control signal The main control unit 10 transmits a control signal with authentication data to the effect control unit 203 via the intermediate unit 20 and the intermediate unit 20.

  Here, an example of a data format of a control signal transmitted from the main control unit 10 to the intermediate unit 20 will be described with reference to a schematic diagram shown in FIG. FIG. 5A shows a normal control signal 310 including control command data 301 and accompanying data 302. The control command data 301 is data unique to the control command. The accompanying data 302 is data accompanying the control command data 301, and is control data necessary for executing processing corresponding to the control command data 301 such as data indicating the current gaming state, for example.

  On the other hand, when transmitting the authentication data to the intermediate unit 20, the main control unit 10 stores the individual authentication data 303 and the operation authentication data 304 in addition to the control command data 301 and the accompanying data 302 as shown in FIG. A control signal 320 with authentication data is generated and output. The individual authentication data 303 includes an individual inspection value, and the operation authentication data 304 includes an operation inspection value.

  Although not shown in FIG. 5, the normal control signal 310 and the control signal with authentication data 320 include a BCC (Block Check Character) and the like, as with a control signal transmitted in general data communication. Sometimes it is. 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 same applies to the normal control signal 310 and the control signal 330 with intermediate authentication information shown in FIG.

  The control signal with authentication data 320 is a control signal with authentication data 320 arranged in the order of control command data 301, accompanying data 302, individual authentication data 303, and operation authentication data 304 as shown in FIG. Not limited to these, they may be arranged in any order. For example, the individual authentication data 303 or the operation authentication data 304 may be provided at the head of the control signal, or the individual authentication data 303 or the operation authentication data 304 may be inserted between the control command data 301 and the accompanying data 302.

In this way, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, the main control unit 10 and the intermediate unit 20 and the operation unit 20 are compared with the case where the individual authentication data 303 or the operation authentication data 304 is transmitted alone. An increase in communication load with the effect control unit 203 can be suppressed. In addition, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, the individual authentication data 303 and the operation authentication data 304 are compared with the case where the individual authentication data 303 and the operation authentication data 304 are transmitted alone. Alternatively, it is possible to reduce the risk that the operation authentication data 304 is extracted and analyzed.
It should be noted that the transmission format of various data and information signals such as the data format of these control signals is generally determined by the intermediate unit 20 and the effect control unit 203 such as the normal control signal 310 and the control signal with intermediate authentication information 330 shown in FIG. The same applies to data and information signal transmission forms related to authentication.

<Intermediate part>
The intermediate unit 20 includes a CPU 20a, a ROM 20b, a RAM 20c, and the like. The CPU 20a performs processing based on a program (program code) stored in advance in the ROM 20b. The RAM 20c stores in advance an authentication count for verifying the operation sequence of the main control unit 10 by comparing with the operation inspection value, and a function number authentication expected value (intermediate operation authentication expected value). Among the storage areas of the RAM 20c, the storage area in which the number of authentications and the expected intermediate operation authentication value are stored in advance can correspond to, for example, the expected value storage unit 21 shown in FIG. The RAM 20c functions as a work area for calculations performed when the CPU 20a executes processing.

  In the first embodiment, the intermediate operation authentication expected value is a function number authentication expected value that is an expected value corresponding to an operation inspection value that is a function number. The intermediate operation authentication expected value for performing authentication using the operation inspection value that is a function number is data formed by associating a plurality of operation inspection values so that the operation order of the main control unit 10 can be determined, for example, This is data that can inspect the order in which operation inspection values are output, such as a data table in which a plurality of operation inspection values are arranged in the order indicating the operation order of the main control unit 10.

In the first embodiment, the processing relating to the authentication of the intermediate unit 20 is as follows [1] to [7].
[1] Reception of control signal The intermediate unit 20 receives from the main control unit 10 a normal control signal consisting only of control command data and accompanying data, or individual authentication data and operation authentication data in addition to control command data and accompanying data. The control signal with authentication data is received. In addition, the intermediate | middle part 20 transmits to the production | presentation control part 203 as it is, when a normal control signal is received.

[2] Extraction of individual authentication data and operation authentication data The intermediate unit 20 extracts individual authentication data and operation authentication data from the control signal with authentication data. Next, the intermediate unit 20 stores the extracted individual authentication data in an individual test value memory which is a predetermined storage area of the RAM 20c. Further, the intermediate unit 20 performs a decryption process corresponding to the encryption process performed on the extracted operation authentication data, extracts an operation test value, and stores the operation test value in a memory for the operation test value, which is a predetermined storage area of the RAM 20c. The operation test values are stored in association with each other so that the order in which the control commands of the main control unit 10 are output can be determined.

  Here, in the first embodiment, for example, the operation test value memory of the RAM 10 c used when generating the operation test value of the main control unit 10 and the RAM 20 c used when extracting the operation test value of the intermediate unit 20. The affiliation source of the memory, such as the operation test value memory, can be identified without confusion even if it is not specified. Therefore, unless otherwise specified, the same name is used regardless of the memory origin (in this example, “operation test value memory” is used). This also applies to the individual test value memory.

[3] Intermediate Operation Authentication The intermediate unit 20 performs intermediate operation authentication on the control command output of the main control unit 10 in the order shown below, using the operation inspection value stored in the operation inspection value memory.
{1} Intermediate operation authentication using operation inspection values
{1-1} The intermediate unit 20 reads out the operation inspection value stored in the operation inspection value memory. When there are a plurality of operation inspection values, they are read in correspondence with the output order.
{1-2} The intermediate unit 20 reads the number of authentications stored in a predetermined storage area of the RAM 20c.

The {1-3} intermediate unit 20 determines whether or not the operation inspection value read in the process {1-1} matches the number of authentications read in the process {1-2}.
{1-4} When the operation inspection value and the number of authentications are the same, that is, when the type of the operation inspection value is the number of authentications and not the function number, the function number expected value and the inspection value that are intermediate operation authentication expected values Do not match, the intermediate unit 20 generates an intermediate operation authentication result indicating non-identity.
{1-5} When the operation inspection value and the number of authentications are not the same, that is, when the type of the operation inspection value is not the number of authentications, the intermediate unit 20 expects intermediate operation authentication stored in a predetermined storage area of the RAM 20c. Read the value (Expected function number authentication value).

The {1-6} intermediate unit 20 determines whether or not the operation inspection value read in the process {1-1} matches the expected function number authentication value read in the process {1-5}. Yes (collation process).
{1-7} When the operation inspection value and the function number authentication expected value are the same, that is, when the type of the operation inspection value is the function number, the intermediate unit 20 indicates that the both are the same Is generated. When the operation inspection value and the function number authentication expected value are not the same, the intermediate unit 20 generates an intermediate operation authentication result indicating that they are not the same. In the first embodiment, since the type of the operation inspection value used for generating the operation authentication data for the first time in the main control unit 10 is a function number, the first intermediate operation authentication result in the processing related to the authentication of the intermediate unit 20 Are generated in which the operation inspection value and the function number authentication expected value are the same.

(Calculation example of intermediate operation authentication result generation)
An example of the calculation for generating the intermediate operation authentication result is shown below.
The intermediate unit 20 generates 1-byte long random numbers (range “0x00” to “0xFF”) with uniform random numbers having the same appearance probability of all values. For example, assume that a random number “0x4B” is generated by a uniform random number. When the intermediate unit 20 generates an intermediate operation authentication result indicating that they are identical, the intermediate unit 20 outputs the data “0x4B” with the value of the least significant bit of the random number “0x4B” generated by the uniform random number as “1”. Generated as an operation authentication result. On the other hand, when the intermediate unit 20 generates an intermediate operation authentication result indicating that they are not identical, the data “0x4A” in which the value of the least significant bit of the random number “0x4B” generated by the uniform random number is set to “0”. As an intermediate operation authentication result.

[4] Generation of Intermediate Authentication Information The intermediate unit 20 uses the individual authentication data extracted in the process [2] and the intermediate operation authentication result obtained in the process [3], or the main part thereof. The intermediate authentication information is generated by using the same encryption processing as that performed when the authentication data is generated by the control unit 10. In the process [3], when the intermediate unit 20 generates an intermediate operation authentication result indicating that the operation inspection value and the intermediate operation authentication expected value are the same, the intermediate unit 20 indicates the intermediate authentication data together with the individual authentication data. When authentication information is generated and an intermediate operation authentication result indicating that the operation inspection value and the expected intermediate operation authentication value are not identical is generated, intermediate authentication information indicating that is generated together with the individual authentication data .

[5] Generation of Control Signal with Intermediate Authentication Information The intermediate unit 20 adds the intermediate authentication information to a normal control signal including control command data and accompanying data, and generates a control signal with intermediate authentication information.

[6] Transmission of control signal with intermediate authentication information The intermediate unit 20 transmits a control signal with intermediate authentication information to the effect control unit 203 and stores each data stored in the individual test value memory and the motion test value memory. Erase. The details of the processing related to authentication of the intermediate unit 20 (the processing [1] to [6]) will be described later. Further, the means for previously storing the intermediate operation authentication expected value and the means for executing the intermediate operation authentication can correspond to, for example, the expected value storage means 21 and the intermediate authentication means 22 shown in FIG.

  Here, an example of a data format of a control signal transmitted from the intermediate unit 20 to the effect control unit 203 will be described with reference to a schematic diagram shown in FIG. When the normal control signal 310 shown in FIG. 5 (1) is transmitted from the main control unit 10, the intermediate unit 20 includes the control command data 301 and the accompanying data 302 as shown in FIG. 6 (1). The normal control signal 310 is transmitted to the effect control unit 203 as it is. On the other hand, when the control signal with authentication data 320 shown in FIG. 5B is transmitted from the main control unit 10, for example, the intermediate unit 20 uses the operation inspection value obtained from the operation authentication data 304. Intermediate operation authentication is performed and an intermediate operation authentication result is generated. Then, the intermediate unit 20 generates the intermediate authentication information 305 by combining the individual authentication data 303 extracted from the control signal with authentication data 320 and the intermediate operation authentication result, for example, with the intermediate authentication information attached as shown in FIG. A control signal 330 is generated and transmitted to the effect control unit 203.

[7] Update of the number of authentications The intermediate unit 20 updates the value of the number of authentications by adding 1 to the value of the number of authentications stored in a predetermined area of the RAM 20c every time the authentication process (intermediate operation authentication) is performed. .

<Production control unit>
The effect control unit 203 includes a CPU 203a, a ROM 203b, a RAM 203c, a VRAM 203d, and the like. The CPU 203a mainly controls the effects during the game, and based on a control command transmitted from the main control unit 10 via the intermediate unit 20 based on a program (program code) stored in advance in the ROM 203b. And effect processing. The ROM 203b stores in advance a program code for the CPU 203a to execute a lottery and a processing of effects and past effect patterns, and also stores in advance in the ROM 10b constituting the main control unit 10. A plurality of individual authentication expected values obtained by performing a plurality of half-group operations using the same data as the predetermined program code to be divided are stored in advance. Among the storage areas of the ROM 203b, the storage area in which the plurality of individual authentication expected values are stored in advance can correspond to, for example, the expected value storage means 31 shown in FIG. The RAM 203c functions as a work area for data and the like in arithmetic processing performed when the CPU 203a executes lottery and presentation processing of effects and arithmetic processing performed when processing related to authentication is executed. Image data to be displayed on the symbol display unit 104 is written in the VRAM 203d.

When the effect control unit 203 receives a control command related to the effect transmitted from the main control unit 10 via the intermediate unit 20, the effect control unit 203 performs a lottery based on the control command, and produces an effect background pattern, a reach effect pattern, and an appearance character. And the like are controlled, and the determined effect is controlled.
In addition, the symbol display unit 104 is connected to the output side of the effect control unit 203, and, for example, a symbol change effect display is developed on the symbol display unit 104 according to the content determined by the lottery.

Usually, the CPU 203a reads a program stored in the ROM 203b, executes various image processing such as background image display processing, symbol image display and variation processing, and character image display processing, and reads necessary image data from the ROM 203b to the VRAM 203d. Write. The background image, the design image, and the character image are superimposed and displayed on the design display unit 104 on the display screen.
That is, the design image and the character image are displayed so as to be seen in front of the background image. At this time, if the background image and the design image overlap at the same position, the design image is preferentially stored in the VRAM 203d by referring to the Z value of the Z buffer of each image data by a known hidden surface removal method such as the Z buffer method. .

  When the production control unit 203 receives the control signal with intermediate authentication information in addition to the processing related to the production outlined above, the production control unit 203 performs the following [1] to [1] based on the program stored in advance in the ROM 203b. 5] is executed. A final authentication judgment is performed from both sides of the individual authentication and the operation authentication by the authentication processing of the effect control unit 203.

[1] Receiving Control Signal The effect control unit 203 determines whether the control signal transmitted from the intermediate unit 20 is a normal control signal consisting only of control command data and accompanying data, or in addition to the control command data and accompanying data. It is determined whether the control signal has intermediate authentication information to which intermediate authentication information including authentication data and an intermediate operation authentication result is added. When the received control signal is a normal control signal, the effect control unit 203 performs the process related to the effect based on the control command data and the accompanying data, and ends the process related to authentication. On the other hand, when the received control signal is a control signal with intermediate authentication information, the effect control unit 203 executes the following processes [2] to [5] on the assumption that the process related to authentication is continued.

[2] Extraction of Individual Authentication Data and Intermediate Operation Authentication Result The effect control unit 203 extracts individual authentication data and intermediate operation authentication result from the control signal with intermediate authentication information. Next, the effect control unit 203 extracts the individual test value by applying the decryption process corresponding to the encryption process used when generating the individual authentication data to the extracted individual authentication data, and is an individual that is a predetermined storage area of the RAM 203c. Store in the inspection value memory. In addition, the effect control unit 203 stores the extracted intermediate operation authentication result in the operation inspection value memory which is a predetermined storage area of the RAM 203c. When the intermediate operation authentication result is encrypted in the intermediate unit 20, the effect control unit 203 performs a decryption process corresponding to the applied encryption process on the intermediate operation authentication result.

[3] Individual authentication The effect control unit 203 performs the semi-group operation in the order shown below on all the individual test values stored in the individual test value memory, so that the individual of the main control unit 10 Perform authentication processing.
{1} The effect control unit 203 performs a half-group operation (hereinafter referred to as a combination process) using all the individual test values stored in the individual test value memory.
{2} The effect control unit 203 reads the stored individual authentication expected value from a predetermined storage area of the ROM 203b.

{3} The effect control unit 203 determines whether or not the calculation result in the process {1} (hereinafter referred to as the combination result) matches the individual authentication expectation value read in the process {2}.
The effect control unit 203 determines that the individual authentication is successful when the combined result matches the expected individual authentication value.
Since the semi-group operation satisfies the above-mentioned combination rule, the individual authentication expected value that is a result obtained by performing the semi-group operation on all the predetermined program codes stored in advance in the ROM 10b of the main control unit 10 And the combined result obtained by performing the semi-group operation on the individual test values for the number of divisions generated from the predetermined program code. At this time, that is, when the individual authentication for the main control unit 10 is successful, the number of individual test values (hereinafter referred to as the number of connections) subjected to the combination process and the number of divisions naturally match. Thereby, the production control unit 203 authenticates the validity of the main control unit 10.
On the other hand, the effect control unit 203 determines that the individual authentication has not been successful when the combined result and the expected individual authentication value do not match.

When the individual authentication is successful in the process {4} {3}, the effect control unit 203 generates an individual authentication result indicating that the individual authentication is successful.
If the individual authentication is not successful in the process of {5} {3}, the effect control unit 203 determines whether or not the number of individual authentication data received from the intermediate unit 20 is equal to or greater than a predetermined number. The predetermined number is an arbitrary number within the range not less than the current number of connections (number of divisions) and not more than the number (maximum number of divisions) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided. is there.
{5-1} If the number of received individual authentication data is less than the predetermined number, the production control unit 203 determines that the individual authentication is not yet possible and can replace the individual authentication result with, for example, authentication halfway data. Any value (for example, all 0 or all 1) having the same data length as the data length of the individual authentication result is generated.
{5-2} If the number of received individual authentication data is greater than or equal to the predetermined number, the effect control unit 203 determines that the individual authentication has not been successful, and displays an individual authentication result indicating that the individual authentication has not been successful. Generate.

(Calculation example of expected generation of individual authentication)
A method for generating the expected individual authentication value will be described with reference to FIG.
The effect control unit 203 holds, as an individual authentication expected value, a value obtained by performing a semigroup operation on the entire predetermined program code to be divided stored in the program code storage area 400. For example, the expected individual authentication value in the case of method A is “0x4E” which is the sum of “0x01” to “0x0C”. Further, the individual authentication expected value in the case of method B is “0x0C” which is an exclusive OR of “0x01” to “0x0C”. The effect control unit 203 holds the same number of individual authentication expected values as the number of half-group operations that are the individual test value generation method by the main control unit 10.

  For example, the individual authentication expected value may be stored in advance in a predetermined storage area of the ROM 203b that configures the effect control unit 203 at the time of manufacture or the like, but is not limited thereto, and is transmitted from another component to the effect control unit 203 It is good to do. Examples of the other components include a prize ball control unit 204 and a dedicated processing unit for generating an individual authentication expected value (hereinafter referred to as an individual authentication expected value calculation unit). Note that the individual authentication expected value calculation unit may transmit the stored individual authentication expected value to the effect control unit 203. In addition, a coefficient necessary for calculating the individual authentication expected value may be transmitted from an external device to the effect control unit 203 and the individual authentication expected value calculation unit via an external connection interface (not shown). In this manner, if the individual authentication expected value is not stored in advance in the predetermined storage area of the ROM 203b that constitutes the effect control unit 203 and is acquired from another component, the individual test value is subsequently changed. It becomes possible to do. This also applies to the intermediate operation authentication expected value and the operation authentication expected value.

[4] Action Authentication The effect control unit 203 determines the intermediate action authentication result stored in the action test value memory and the number of individual test values that are targets of the combination process when the individual authentication is successful (the number of connections). ) Are used to authenticate the operation of the pachinko gaming machine 1 in the order shown below. The effect control unit 203 specifies the number of connections prior to operation authentication.

{1} Operation authentication using intermediate operation authentication result
{1-1} The effect control unit 203 reads the intermediate motion authentication result stored in the motion test value memory. In the first embodiment, in the first operation authentication, an intermediate operation authentication result indicating that the operation inspection value and the intermediate operation authentication expected value are the same is read.
{1-2} The effect control unit 203 reads the expected operation authentication value used for the current operation authentication from the predetermined storage area of the ROM 203b. As for the operation authentication expected value, whether or not the type of operation inspection value recognized as being used for generating the operation authentication data by the main control unit 10 in the current authentication process and the corresponding intermediate operation authentication expected value are the same This information is predicted in advance and stored in advance in the effect control unit 203 as information indicating the same or non-identical information. In the first embodiment, the expected operation authentication value read for the first time is set in advance as information indicating the same.

{1-3} The production control unit 203 determines whether or not the intermediate operation authentication result read out in the process of {1-1} matches the operation authentication expected value read out in the process of {1-2}. to decide.
{1-4} The production control unit 203 determines that the operation authentication is successful when the intermediate operation authentication result and the operation authentication expected value match, and when the intermediate operation authentication result and the operation authentication expected value do not match, Judge that the operation authentication was not successful. In the first embodiment, the initial intermediate operation authentication result transmitted from the intermediate unit 20 indicates the same, and the initial operation authentication expected value read by the effect control unit 203 indicates the same. Since it is information, it is determined that the operation authentication is successful.

    When the operation authentication is successful in the processing of {1-5} {1-4}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is successful and is stored in the operation inspection value memory. Erase all existing data. Then, the effect control unit 203 determines whether or not to change the type of expected operation authentication value to be read next time in accordance with a predetermined agreement based on the number of connections found in the process [3]-{3}. The predetermined agreement is the same as that in which the main control unit 10 selects the type of the operation inspection value used for generating the operation authentication data. In other words, the type of expected operation authentication value is changed when the number of connections is odd, and the type of expected operation authentication value currently used is continued when the number of connections is even. If the operation authentication is not successful in the process {1-4}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is not successful.

[5] Processing Based on Authentication Result The effect control unit 203 uses the individual authentication result obtained by the individual authentication that is the processing of [3] and the operation authentication result obtained by the operation authentication that is the processing of [4]. Then, the normality of the pachinko gaming machine 1 is authenticated from both the individual authentication and the operation authentication, and a final authentication judgment is made. When both the individual authentication result obtained by the individual authentication that is the process of [3] and the operation authentication result obtained by the operation authentication that is the process of [4] The control unit 203 executes processing based on the control command data and accompanying data included in the control signal with intermediate authentication information, and erases each data stored in the individual test value memory and the operation test value memory. Then, the process related to authentication is terminated. On the other hand, either the individual authentication result obtained by the individual authentication that is the process [3] or the operation authentication result obtained by the operation authentication that is the process [4] was a result indicating that authentication was unsuccessful. In this case, the control command data and the accompanying data are discarded, and processing such as notification that an illegal act has been detected is performed, and each data stored in the individual test value memory and the operation test value memory is erased and authenticated. The process related to is terminated.

A chance button detection unit 220 that detects that the chance button 117 is operated is connected to the input side of the effect control unit 203. In addition, a speaker 277 is connected to the output side of the effect control unit 203 so that sound is output as determined by the effect control unit 203.
A lamp control unit 205 is provided on the output side of the effect control unit 203.

<Other control units>
The lamp control unit 205 operates the program read from the ROM 205b based on the control command transmitted from the effect control unit 203 to execute the effect process, the ROM 205b that stores the program and various effect pattern data, and the CPU 205a. A RAM 205c and the like functioning as a data work area at the time of arithmetic processing are provided. The lamp control unit 205 controls the lamp 262, the effect lights 111a and 111b, and the effect agent actuating device 254. The stage effect actuating device 254 is configured by a motor, a solenoid, and the like that actuate a stage role such as the stage role 115.

The lamp control unit 205 performs lighting control and the like for various lamps 262 provided on the game board 101 and underframe, etc., and performs lighting control and the like for the plurality of lights 112 that respectively constitute the effect lights 111a and 111b. In order to change the irradiation direction of the light from each light 112, drive control for the motor is performed.
Further, the lamp control unit 205 is based on the control command transmitted from the effect control unit 203, and the effect agent actuating device 254 that operates the solenoid of the effect agent actuating device 254 that operates the effect agent 115 and the collar unit 116. Drive control for the motor is performed.

  The prize ball control unit 204 is connected to the main control unit 10 so as to be able to transmit and receive. The prize ball control unit 204 performs prize ball control based on a program stored in the ROM 204b. The prize ball control unit 204 includes a CPU 204a that executes a prize ball control process by operating a program stored in the ROM 204b, and a RAM 204c that functions as a data work area during the calculation process of the CPU 204a.

The winning ball control unit 204 makes each of the winning ports (first starting port 105, second starting port 120, normal winning port 107, first big winning port 109c, second big winning a prize) to the payout unit 291 connected thereto. Control is performed to pay out the number of prize balls corresponding to the game ball that has entered the mouth 129c). The award ball control unit 204 detects an operation of launching a game ball with respect to the launch unit 292 and controls the launch of the game ball. The launching unit 292 launches a game ball for gaming, and includes a sensor (not shown) that detects a game operation by the player, a solenoid that launches the game ball, and the like (not shown). When the award ball control unit 204 detects a game operation by the sensor of the launch unit 292, the prize ball control unit 204 intermittently fires a game ball by driving a solenoid or the like in response to the detected game operation, thereby playing the game area 103 of the game board 101. A game ball is sent out.
The payout unit 291 includes a motor for paying out a predetermined number from the game ball storage unit.

  The main control unit 10, the intermediate unit 20, the production control unit 203, the prize ball control unit 204, and the lamp control unit 205 configured as described above are different printed boards (for example, the main control unit 10 is a main control board, The intermediate unit 20 is mounted on an intermediate board, the effect control unit 203 is mounted on an effect control board, the prize ball control unit 204 is mounted on a prize ball control board, and the lamp control unit 205 is mounted on a lamp control board. Among these, “peripheral board” is used as a general term for the intermediate board, the effect control board, the prize ball control board, and the lamp control board. For example, the intermediate unit 20 can 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.

  Next, the operation of the pachinko gaming machine 1 configured as described above will be described with reference to the drawings. In the following description, “transmit a control command” means “transmit a control signal including data indicating the control command (control command data)”. For example, the individual authentication shown in FIG. The presence of data, operation authentication data, and accompanying data is not considered.

Processing including control command transmission by the main control unit 10 to the intermediate unit 20 and the prize ball control unit 204 will be described with reference to flowcharts shown in FIGS.
First, the main control unit 10 executes an initial setting process associated with power-on of the pachinko gaming machine 1 (step S1), and then proceeds to step S2. When the pachinko gaming machine 1 is turned on, the peripheral board starts up and performs initialization of the RAM area in order to reliably capture the control command received from the main control board by the peripheral board. After that, the main control board is configured to stand up. As the initial setting process, the main control unit 10 sets, for example, a predetermined value for the stack pointer, and waits for the intermediate unit 20, the effect control unit 203, and the prize ball control unit 204 to enter a standby state. And wait for a predetermined time (for example, about 1 second).

  In step S2, the main control unit 10 transmits a power-on command to the intermediate unit 20 and the prize ball control unit 204, and then proceeds to step S3. When receiving the power-on command, the intermediate unit 20 transmits the power-on command to the effect control unit 203. When the power-on command is received, the effect control unit 203 controls the design display command at the time of power-on to each of the symbol display unit 104 and the lamp control unit 205, specifically, the customer in the non-game state of the gaming machine. A customer waiting demo command for displaying a waiting demo screen or a control command for lighting a lamp or the like is transmitted.

  The power-on command indicates a control command for executing processing associated with power-on after power-on. After each control board is started up, the main control unit 10 controls the production via the intermediate unit 20 and the intermediate unit 20. Control command transmitted to the unit 203 and the prize ball control unit 204, and control for transmitting initial control information for controlling a game at the time of start-up after power-on, for example, control mode, backup data, etc. A command or a control command for controlling the initial effect display, for example, a control command for starting various demonstration displays such as a customer waiting demonstration. 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.

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

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

  In step S6, the main control unit 10 transmits a customer waiting demonstration command to the intermediate unit 20, and then proceeds to step S7. When receiving the customer waiting demo command, the intermediate unit 20 transmits the customer waiting demo command to the effect control unit 203. When receiving the customer waiting demonstration command, the effect control unit 203 transmits a control signal for the customer waiting demonstration to each of the symbol display unit 104 and the lamp control unit 205.

  On the other hand, if the determination result in step S5 is “NO”, that is, if a predetermined time has not elapsed since the start of the power-on demonstration (or the customer waiting demo), the main control unit 10 Proceed to S7. In step S <b> 7, the main control unit 10 detects whether or not 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 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. If a game ball has entered the mouth 120, the main control unit proceeds to step S8.

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

  In step S8, the main control unit 10 clears the time that has been measured since the start of the customer waiting demo (or demo at power-on), and then proceeds to step S9. In step S9, the main control unit 10 adds 1 to the number of undrawn winning prizes. If the first start port detection unit 221 or the second start port detection unit 225 detects a plurality of game balls entering, the main control unit 10 enters the number of undrawn winnings in this step S9. Add the corresponding numbers. Then, the main control unit 10 proceeds to step S10. In step S10, the main control unit 10 randomly acquires one jackpot determination random number from a random number counter (for example, counts 0 to 250) prepared in advance, and then proceeds to step S11. In step S11, the main control unit 10 subtracts 1 from the number of undrawn winning prizes, and then proceeds to step S12.

  In step S12, for example, the main control unit 10 refers to the jackpot determination data table stored in advance in the ROM 10b, 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 value. In step S12, the main control unit 10 refers to the jackpot determination data table, for example, when the acquired big hit determination random number is an out-of-range random number, and further “reach with reach” or “without reach”. It is also judged whether it is “out of”. If the determination result in step S12 is “YES”, that is, if the jackpot determination random number acquired in step S10 is a predetermined jackpot random number, the main control unit 10 proceeds to step S13.

  In step S13, the main control unit 10 causes the intermediate unit 20 to receive a jackpot including control data (accompanying data) such as, for example, a jackpot type code (whether it is a normal hit or a probability fluctuation), reach, symbol variation time, and the like. After transmitting the reach command (design variation command), the process proceeds to step S14. When the jackpot reach command (symbol variation command) is received, the intermediate unit 20 transmits the jackpot reach command (symbol variation command) to the effect control unit 203. In step S14, the main control unit 10 determines whether or not the symbol variation time has elapsed. If the determination result in step S14 is “NO”, that is, if the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S14 is “YES”, and the main control unit 10 proceeds to step S15.

  In step S15, the main control unit 10 transmits a symbol stop command to the intermediate unit 20, and then proceeds to step S16. When receiving the symbol stop command, the intermediate unit 20 transmits the symbol stop command to the effect control unit 203. In step S16, the main control unit 10 transmits a jackpot start command to the intermediate unit 20, and then proceeds to step S17. When the jackpot start command is received, the intermediate unit 20 transmits the jackpot start command to the effect control unit 203. In step S17, the main control unit 10 sequentially transmits to the intermediate unit 20 commands corresponding to each of the big hits (big hit command), and after completing the transmission of the big hit command for all rounds, the main control unit 10 proceeds to step S18. When the jackpot command corresponding to each round is sequentially received, the intermediate unit 20 sequentially transmits the jackpot command corresponding to each round to the effect control unit 203. In step S18, the main control unit 10 transmits a jackpot end command to the intermediate unit 20, and then proceeds to step S22. When receiving the jackpot end command, the intermediate unit 20 transmits the jackpot end command to the effect control unit 203.

  On the other hand, if the determination result in step S12 is “NO”, that is, if the jackpot determination random number obtained in the process of step S10 is not a predetermined jackpot random number, the main control unit 10 proceeds to step S19. In step S19, the main control unit 10 determines that the “reach with a reach” command is “out-of-reach reach command (design variation command)”, and the “out-of-reach command” indicates a “out-of-reach command (design variation command)”. ”Is transmitted to the intermediate unit 20, and then the process proceeds to step S20. When receiving the outlier reach command or the outlier command, the intermediate unit 20 transmits the control command (design variation command) to the effect control unit 203.

  In step S20, the main control unit 10 determines whether or not the symbol variation time has elapsed. When the determination result of step S20 is “NO”, that is, when the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S20 is “YES”, and the main control unit 10 proceeds to step S21. In step S21, the main control unit 10 transmits a symbol stop command to the intermediate unit 20, and then proceeds to step S22. When receiving the symbol stop command, the intermediate unit 20 transmits the symbol stop command to the effect control unit 203.

  In step S22, the main control unit 10 determines whether or not the power of the pachinko gaming machine 1 has been turned off. If the determination result in step S22 is “NO”, that is, if the power of the pachinko gaming machine 1 is not turned off, the main control unit 10 returns to step S3 shown in FIG. repeat.

  On the other hand, when the determination result of step S22 is “YES”, that is, when the power of the pachinko gaming machine 1 is turned off, the main control unit 10 proceeds to step S23. In step S <b> 23, the main control unit 10 transmits a termination process command to the intermediate unit 20 and then terminates a series of processes. When the end process command is received, the intermediate unit 20 transmits the end process command to the effect control unit 203.

  Here, FIG. 9 shows a timing chart as an example of the transmission timing of the jackpot related command (the jackpot reach command, jackpot start command, jackpot command, jackpot end command). The jackpot reach command shown in FIG. 9 (1) is transmitted at random. The jackpot start command shown in FIG. 9 (2) is transmitted only once when shifting to the jackpot state when a jackpot has actually occurred. Furthermore, the jackpot command shown in FIG. 9 (3) is continuously transmitted for each round after shifting to the jackpot state. Also, the jackpot end command shown in FIG. 9 (4) is transmitted only once when all rounds of the jackpot state are completed and the normal state is entered.

  Next, processing by the effect control unit 203 will be described. In the following, regarding the process of the effect control unit 203 at the time of symbol variation (when a jackpot reach command (see step S13 shown in FIG. 8) or a loss reach command (see step S19 shown in FIG. 8) is received) and a jackpot reach command. explain.

First, the symbol variation process by the effect control unit 203 will be described with reference to the flowchart shown in FIG.
The effect control unit 203 receives either a jackpot reach command (see step S13 shown in FIG. 8) or a miss reach command (see step S19 shown in FIG. 8), which is a symbol variation command, from the main control unit 10 through the intermediate unit 20. Is determined (see step S31 in FIG. 10). When the determination result is “NO”, the effect control unit 203 repeats the determination. Then, when either the jackpot reach command or the miss reach command is received, the determination result in step S31 is “YES”, and the effect control unit 203 proceeds to step S32.

  In step S32, the effect control unit 203 randomly acquires one random effect selection random number from random numbers (for example, 0 to 250) prepared in advance, and then proceeds to step S33. In step S33, the effect control unit 203 selects a variation effect type based on the variable effect selection random number acquired in the process of step S32, and then proceeds to step S34.

  In step S34, the effect control unit 203 transmits an effect start command for each variable effect to the symbol display unit 104 and the lamp control unit 205, and then proceeds to step S35. In step S35, the effect control unit 203 determines whether or not the effect time of the variable effect has elapsed. If the determination result in step S35 is “NO”, that is, if the effect time of the changing effect has not elapsed, the effect control unit 203 proceeds to step S36.

  In step S36, the effect control unit 203 determines whether or not a symbol stop command (see steps S15 and S21 shown in FIG. 8) has been received from the main control unit 10 via the intermediate unit 20. If the determination result in step S36 is “NO”, that is, if the symbol stop command has not been received, the effect control unit 203 returns to step S35 and repeats the processing after step S35.

  On the other hand, if the determination result in step S36 is “YES”, that is, if a symbol stop command is received, the effect control unit 203 proceeds to step S37. In addition, when the determination result in step S35 is “YES”, that is, when the effect time of the variable effect has elapsed, the effect control unit 203 proceeds to step S37. In step S37, the effect control unit 203 transmits an effect stop command to the symbol display unit 104 and the lamp control unit 205, and then ends the series of processes.

Next, the process at the time of the big hit by the production | presentation control part 203 is demonstrated with reference to the flowchart shown in FIG.
First, the effect control unit 203 determines whether or not a jackpot start command (see step S16 shown in FIG. 8) is received from the main control unit 10 via the intermediate unit 20 (see step S41 in FIG. 11). When the determination result is “NO”, the effect control unit 203 repeats the determination. When the jackpot start command is received, the determination result in step S41 is “YES”, and the effect control unit 203 proceeds to step S42.

  In step S42, the effect control unit 203 transmits a jackpot start processing command to the symbol display unit 104 and the lamp control unit 205, and then proceeds to step S43. In step S43, the effect control unit 203 determines whether or not a round-by-round jackpot command (see step S17 shown in FIG. 8) has been received from the main control unit 10 via the intermediate unit 20. When the determination result is “NO”, the effect control unit 203 repeats the determination. And if the jackpot command according to round is received, the judgment result of step S43 will be "YES", and the production | presentation control part 203 will progress to step S44.

  In step S44, the effect control unit 203 transmits to the symbol display unit 104 or the lamp control unit 205 a round-by-round processing command corresponding to the received round-by-round jackpot command, and then proceeds to step S45. In step S45, it is determined whether a jackpot end command (see step S18 shown in FIG. 8) is received from the main control unit 10 via the intermediate unit 20. When the determination result is “NO”, the effect control unit 203 repeats the determination. When the jackpot end command is received, the determination result in step S45 is “YES”, and the effect control unit 203 proceeds to step S46. In step S46, the effect control unit 203 transmits the received jackpot end command to the symbol display unit 104 and the lamp control unit 205, and then ends the series of processes.

Next, lamp control processing by the lamp control unit 205 will be described. Here, processing when a symbol variation command is received from the effect control unit 203 (during symbol variation) will be described with reference to the flowchart shown in FIG.
First, the lamp control unit 205 determines whether or not an effect start command (see step S34 shown in FIG. 10) has been received from the effect control unit 203 (see step S51 in FIG. 12). When the determination result is “NO”, the lamp control unit 205 repeats the determination. Then, when an effect start command is received, the determination result in step S51 is “YES”, and the lamp control unit 205 proceeds to step S52.

  In step S52, the lamp control unit 205 reads, for example, data stored in advance for each command from the ROM 205b, and then proceeds to step S53. In step S53, the lamp control unit 205 executes a selection routine for each command, and then proceeds to step S54. In step S54, the lamp control unit 205 sets the lamp data, and then proceeds to step S55.

  In step S55, the lamp control unit 205 outputs the lamp data to the lamp 262, and then proceeds to step S56. Accordingly, the lamp 262 is turned on or off based on the lamp data output from the lamp control unit 205. In step S56, the lamp control unit 205 determines whether or not an effect stop command (see step S37 shown in FIG. 10) is received from the effect control unit 203. When the determination result is “NO”, the lamp control unit 205 returns to Step S55 and repeats the processes after Step S55. On the other hand, if the determination result in step S56 is “YES”, that is, if an effect stop command is received from the effect control unit 203, the lamp control unit 205 proceeds to step S57. In step S57, the lamp control unit 205 ends the series of processes after stopping the output of the lamp data.

  As described above, the effect control unit 203 and the lamp control unit 205 perform various processes based on the control command transmitted from the main control unit 10. The same applies to the prize ball control unit 204. Hereinafter, “peripheral part” is used as a generic term for the effect control unit 203, the prize ball control unit 204, and the lamp control unit 205. Accordingly, the peripheral portion 30 of the gaming machine 1 according to the first embodiment shown in FIG. 1 includes effect control means having the function of the effect control section 203, prize ball control means having the function of the prize ball control section 204, and lamp control. Lamp control means having the function of the unit 205 is provided.

In the first embodiment, the main control unit 10 generates individual authentication data for the number of divisions using a predetermined program code, and generates operation authentication data. The individual authentication data and the operation authentication data Is added to the control command and transmitted to the intermediate unit 20.

  The intermediate unit 20 performs intermediate operation authentication using the operation inspection value, and performs intermediate authentication obtained by performing encryption processing on the obtained intermediate operation authentication result and the individual authentication data transmitted from the main control unit 10. Information is transmitted to the production control unit 203. Then, the production control unit 203 performs the operation authentication using the intermediate operation authentication result obtained from the intermediate authentication information received from the intermediate unit 20 and performs the individual authentication using the individual authentication data to obtain the final authentication result. obtain. In this way, the authentication process is performed with the intermediate unit 20 and the production control unit 203 as the authenticator and the main control unit 10 as the person to be authenticated, and the normality of the pachinko gaming machine 1 is authenticated. By this authentication process, the fraudulent act can be detected and fraud to the pachinko gaming machine 1 can be prevented, and the pachinko gaming machine 1 caused by electrical noise or mechanical vibration applied from the outside can be prevented. Malfunctions can be reduced.

  Hereinafter, processing related to authentication performed between the main control unit 10, the intermediate unit 20, and the effect control unit 203 will be described. Hereinafter, processing related to authentication of the main control unit 10 and the intermediate unit 20 will be described with reference to the flowcharts shown in FIGS. The same procedure is performed.

  FIG. 13 is a flowchart illustrating an example of a processing procedure related to authentication by the main control unit 10. The main control unit 10 determines whether it is the transmission timing of the authentication data while transmitting a normal control signal (step S61) (step S62). If the determination result is NO, the main control unit 10 returns to step S61 and performs the determination in step S62 again. When the authentication data transmission timing comes, that is, when the output control command becomes a predetermined control command, the determination result in step S62 is “YES”, and the main control unit 10 proceeds to step S63 to determine the number of divisions. The method for determining the number of divisions is arbitrary. The number of divisions may be determined before the transmission timing of authentication data.

  Next, the main control unit 10 divides a predetermined program code by the determined number of divisions, performs a semi-group operation on each of the divided data, and calculates an individual test value (step S64). The value is subjected to encryption processing to generate individual authentication data (step S65). By this processing, individual test values and individual authentication data corresponding to the number of divisions are generated. The individual test value may be generated before the authentication data transmission timing comes.

  Next, the main control unit 10 selects the type of operation test value used to generate the operation authentication data to be transmitted to the intermediate unit, and acquires the selected type of operation test value from the operation test value memory (step S66). . Specifically, it is an operation inspection value of any kind of a function number or the number of times of authentication, and is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the intermediate unit 20 and the effect control unit 203. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, and generates operation authentication data (step S67).

  Subsequently, the main control unit 10 adds the individual authentication data and the operation authentication data to the control command data, and transmits a control signal with authentication data to the intermediate unit 20 (step S68). The control signal with authentication data may be transmitted continuously, or may be mixed with a normal control signal and transmitted. The main control unit 10 returns to step S68 and repeats transmission of the control signal with authentication data until all authentication data (individual authentication data and operation authentication data) is transmitted (step S69: NO). When there is untransmitted authentication data among the generated authentication data (step S69: NO), the main control unit 10 does not newly generate authentication data, and always returns to step S68 to transmit a control signal with authentication data. I do. Further, the control command for adding the authentication data is not particularly limited and may be an arbitrary control command. When all the authentication data is transmitted (step S69: YES), the process proceeds to step S70.

  Subsequently, the main control unit 10 determines whether or not the number of divisions determined in step S63 is a predetermined value (step S70). The predetermined value is an odd number in the first embodiment. When the number of divisions is a predetermined value (step S70: YES), the main control unit 10 changes the type of the operation inspection value used in the process related to the next authentication (step S71), and one of the operation inspection values. The value of the number of authentications is incremented by 1 and the value of the number of authentications is updated (step S72), and the series of processing ends. On the other hand, if the number of divisions is not a predetermined value (step S70: NO), the value of the number of authentications is updated without changing the type of the operation inspection value used for generating the operation authentication data in the next authentication process. Then (step S72), a series of processing ends.

  Next, processing related to authentication by the intermediate unit 20 will be described. FIG. 14 is a flowchart illustrating an example of a processing procedure related to authentication by the intermediate unit 20. First, the intermediate unit 20 determines whether or not a control signal as shown in FIG. 5 transmitted from the main control unit 10 has been received (step S80). If the determination result is “NO”, the intermediate unit 20 repeats the determination. And if the control signal transmitted from the main control part 10 is received (step S80: YES), the intermediate part 20 will progress to step S81.

  In step S81, the intermediate unit 20 determines whether or not operation authentication data is included in the received control signal. When operation authentication data is included in the received control signal (step S81: YES), the intermediate unit 20 proceeds to step S82. Here, the determination whether or not the operation authentication data is included in the control signal is, for example, that the amount of data of the control signal is larger than that of the control signal with authentication data including only the individual authentication data as a normal control signal or authentication data. And whether or not the control command data or any data constituting the accompanying data or separately provided identification data (not shown) indicates that the operation authentication data is included in the control signal. It is done by judging. In the process of step S81, the intermediate unit 20 does not determine whether or not each authentication data is included in the received control signal, but the control command data included in the control signal controls the predetermined control command. It may be determined whether it is command data.

  If the received control signal includes operation authentication data (step S81: YES), that is, if the received control signal is a control signal with authentication data including individual authentication data and operation authentication data, the intermediate unit 20 In addition to extracting the individual authentication data included in the received control signal with authentication data, the operation authentication data is extracted and decrypted to extract an operation inspection value (step S82). The intermediate unit 20 stores the extracted individual authentication data in the individual test value memory and the extracted operation test value in the operation test value memory, and proceeds to step S83.

  Subsequently, the intermediate unit 20 compares the operation inspection value acquired in step S82 with the number of authentications stored in advance, and collates whether or not they are the same (step S83). If they are not the same (step S83: NO), the process proceeds to step S84. Subsequently, the intermediate unit 20 compares the operation inspection value acquired in step S82 with the function number authentication expected value (intermediate operation authentication expected value) held in advance, and collates whether or not they are the same ( Step S84). When both are the same (step S84: YES), the intermediate unit 20 generates an intermediate operation authentication result indicating the same (step S85). Then, the intermediate unit 20 generates intermediate authentication information indicating the same together with the generated intermediate operation authentication result and the individual authentication data stored in the individual test value memory (step S86).

  On the other hand, when the operation inspection value and the number of authentications are the same (step S83: YES), or when the operation inspection value and the function number authentication expected value are not the same (step S84: NO), the intermediate unit 20 An intermediate operation authentication result indicating non-identity is generated (step S87). Then, the intermediate unit 20 generates intermediate authentication information indicating non-identity together with the generated intermediate operation authentication result and the individual authentication data stored in the individual test value memory (step S86). Thereafter, the intermediate unit 20 generates a control signal with intermediate authentication information including the generated intermediate authentication information, transmits it to the effect control unit 203 (step S88), and stores it in the individual test value memory and the motion test value memory. Delete the stored data. Thereafter, the intermediate unit 20 updates the value of the number of authentications by adding 1 to the value of the number of authentications (step S89), and ends the series of processes. When the operation inspection value and the number of authentications are not the same, and the operation inspection value and the function number authentication expected value are not the same (step S84: NO), the intermediate unit 20 determines that the operation authentication is unsuccessful. An authentication unsuccessful signal that reports that authentication was unsuccessful may be transmitted to the effect control unit 203. In this case, the presentation control unit 203 that has received the authentication unsuccessful signal determines that the authentication is unsuccessful, and outputs a notification signal for reporting the fact.

  In step S81, if the operation control data is not included in the received control signal, that is, if the received control signal is a normal control signal, or authentication that does not include the operation authentication data but includes individual authentication data. If it is a control signal with data (step S81: NO), the intermediate unit 20 does not perform the authentication process and transmits the received normal control signal as it is to the effect control unit 203 (step S90), and ends the series of processes. To do. In the first embodiment, the intermediate operation authentication expected value is used as the function number authentication expected value for collating with the operation inspection value related to the function number. However, the intermediate operation authentication expected value may be used as the number of times of authentication. In the first embodiment, both the function number authentication expected value and the number of authentications are used for collation with the operation inspection value. However, only one of the function number authentication expected value and the number of authentications is subjected to intermediate operation authentication. The intermediate operation authentication may be performed by collating with the operation inspection value using the expected value. Thus, by performing the intermediate operation authentication by one authentication process with one intermediate operation authentication expected value, it is possible to simplify the processing of the intermediate part and reduce the processing load.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 15 is a flowchart illustrating an example of a processing procedure related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether a control signal is received from the intermediate unit 20 (step S91). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the intermediate part 20, the judgment result of step S91 will be "YES", and the production | presentation control part 203 will progress to step S92.

  In step S92, the effect control unit 203 determines whether intermediate authentication information or individual authentication data is included in the received control signal. If the determination result in step S92 is “YES”, that is, if the received control signal includes intermediate authentication information or individual authentication data, the effect control unit 203 proceeds to step S93. Here, whether or not the control signal includes intermediate authentication information or individual authentication data is determined by, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, Determining whether any bits constituting the data or accompanying data or separately provided identification data (not shown) indicate that intermediate authentication information or individual authentication data is included, or It may be determined whether or not the control command data included in the control signal is control command data of a predetermined control command set in advance for performing the authentication process.

  When the received control signal includes intermediate authentication information or individual authentication data (step S92: YES), that is, when the received control signal is a control signal with intermediate authentication information, the effect control unit 203 receives the received intermediate signal. The intermediate operation authentication result included in the control signal with authentication information is extracted, and individual authentication data is extracted and decrypted to extract an individual test value (step S93). Alternatively, if the control signal includes individual authentication data, an individual test value is extracted in the same manner (step S93). The effect control unit 203 stores the extracted individual test value in the individual test value memory and the extracted intermediate motion authentication result in the motion test value memory, and proceeds to step S94. In step S92, if the received control signal does not include intermediate authentication information, that is, if the received control signal is a normal control signal (step S92: NO), the effect control unit 203 performs the authentication process. Without proceeding to step S103.

  Next, the effect control unit 203 performs a semi-group operation (joining process) on all the individual test values in the individual test value memory as the individual authentication process (step S94). If there is one test value in the individual test value memory, the process proceeds to step S95 without performing the combining process. Then, the production control unit 203 collates the calculation result (combination result) of the combination process with the held individual authentication expected value, and determines whether or not the combined result and the individual authentication expected value match ( Step S95). When the combined result matches the expected individual authentication value (step S95: YES), the effect control unit 203 determines that the individual authentication of the main control unit 10 has succeeded (step S96).

  Subsequently, the effect control unit 203 refers to the acquired intermediate operation authentication result stored in the operation inspection value memory as the operation authentication process, and the intermediate operation authentication result in the intermediate unit 20 is obtained from the main control unit 10. It is confirmed whether the transmitted operation inspection value and the intermediate operation authentication expected value (function number) previously held as an expected value in the intermediate unit 20 indicate the same or non-identical values (step S97). . And the production | generation control part 203 reads the operation | movement authentication expected value previously hold | maintained as an expected value, and collates whether an intermediate | middle operation | movement authentication result and an operation | movement authentication expected value correspond (step S98). When the intermediate operation authentication result matches the operation authentication expected value (step S98: YES), the effect control unit 203 makes the operation authentication of the main control unit 10 and the intermediate unit 20 successful (step S99), and in step S96. Together with the individual authentication result, it is determined that the authentication process of the current pachinko gaming machine 1 is successful (step S100), and the process proceeds to step S101. On the other hand, if the intermediate operation authentication result and the operation authentication expected value do not match (step S98: NO), the effect control unit 203 makes the operation authentication of the main control unit 10 and the intermediate unit 20 unsuccessful, and this pachinko gaming machine It is determined that the authentication process 1 has not succeeded (step S105), and the process proceeds to step S106.

  Subsequently, the effect control unit 203 determines whether or not the number of connections determined in step S94 is a predetermined value (step S101). The predetermined value is an odd number in the first embodiment, similarly to the processing in the main control unit 10. When the number of connections is a predetermined value (step S101: YES), the effect control unit 203 changes the expected operation authentication value used in the next authentication process (step S102), and the process proceeds to step S103. On the other hand, when the number of connections is not a predetermined value (step S101: NO), the process proceeds to step S103 without changing the expected operation authentication value used in the next authentication process. In step S103, the effect control unit 203 deletes the data stored in the individual test value memory and the motion test value memory and performs a process based on the control command data and the accompanying data, and then ends the series of processes. To do.

  On the other hand, in step S95, when the combined result and the individual authentication expected value do not match (step S95: NO), the effect control unit 203 receives the predetermined number or more of individual authentication data (step S104: NO), step S91. Returning to the above, the process of receiving the individual authentication data and combining the individual test values is repeated. When the individual authentication data of a predetermined number or more is received (step S104: YES), the production control unit 203 determines that the individual authentication of the main control unit 10 is unsuccessful and the authentication process of the current pachinko gaming machine 1 is not successful. (Step S105), the process proceeds to Step S106. In step S106, the effect control unit 203 interrupts the processing based on the control command data and the accompanying data, discards the data, and sends a notification signal for notifying the illegal act to the symbol display unit 104 and the lamp control unit 205. Or after transmitting to the center control apparatus etc. which manage the pachinko game machine 1, a series of processes are complete | finished. In the process of step S106, the effect control unit 203 may perform only one of data discarding and notification.

  Based on the received notification signal, the symbol display unit 104, the lamp control unit 205, and the like perform an effect of notifying the main control unit 10 that there is a risk of fraud. 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.

  Next, of the processes shown in FIGS. 13, 14, and 15, the operation control value used for generating the operation authentication data in the main control unit 10 and the operation authentication expected value change process in the effect control unit 203 are shown. A specific example will be described. FIG. 16 is a sequence diagram illustrating an example of the flow of data among the main control unit 10, the intermediate unit 20, and the effect control unit 203.

  First, the main control unit 10 proceeds to the process of step S111, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S112. For example, the main control unit 10 determines that the current number of divisions is three. In step S112, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into three blocks (storage areas), and uses the program code stored in each block to 3 One individual test value is generated (step S112), and the individual test value is subjected to encryption processing to generate individual authentication data (step S113).

  Next, the main control unit 10 selects the type of operation inspection value used for generating the operation authentication data, and acquires the selected type of operation inspection value from the operation inspection value memory (step S114). Specifically, it is an operation inspection value of any kind of a function number or the number of times of authentication, and is determined at the time of the process related to the previous authentication. Note that the type of the first operation inspection value is determined in advance between the intermediate unit 20 and the effect control unit 203, and is a function number here. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, generates operation authentication data (step S115), generates an authentication data-added control signal together with the individual authentication data, 20 (step S116). Thereafter, the main control unit 10 selects the type of operation inspection value to be used in the next authentication-related process based on the number of divisions determined in step S111 (step S117). Here, since the number of divisions = 3 and an odd number, the type of the operation inspection value to be used next time is changed from the function number to the number of times of authentication. Then, the value of the authentication count is updated by adding 1 to the value of the authentication count that is one of the operation inspection values (step S118).

  Next, processing in the intermediate unit 20 will be described. When the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S119), the intermediate unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and performs the operation inspection from the operation authentication data. A value is extracted (step S120).

  Next, the intermediate unit 20 collates the operation inspection value with the number of authentications held in advance (step S121). In this case, since the type of the operation inspection value transmitted from the main control unit 10 is a function number, both are not identical (step S121). Subsequently, the intermediate unit 20 collates the operation inspection value with the function number authentication expected value (intermediate operation authentication expected value) held in advance (step S122). In the first embodiment, the expected intermediate operation authentication value is a function number. This time, since the type of the operation inspection value transmitted from the main control unit 10 is the function number, both are the same (step S122). Then, the intermediate unit 20 generates an intermediate operation authentication result indicating the same, and combines this with the individual authentication data transmitted from the main control unit 10 to generate intermediate authentication information indicating the same (step S123). A control signal with intermediate authentication information including the intermediate authentication information is transmitted to the effect control unit 203 (step S124). Further, the intermediate unit 20 adds 1 to the value of the number of authentications and updates the value of the number of authentications (step S125).

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with intermediate authentication information transmitted from the intermediate unit 20 (step S126), the production control unit 203 extracts the individual authentication data and the intermediate operation authentication result from the control signal with intermediate authentication information, and the individual authentication data. The individual test value is extracted from (step S127). Then, the effect control unit 203 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S128). Thereafter, the combined result is compared with the individual authentication expected value held in advance, and when the result matches the individual authentication expected value, the effect control unit 203 determines that the individual authentication of the main control unit 10 has been successful (step S129). Here, when combining processing is performed using three individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 3.

  Next, the effect control unit 203 refers to the extracted intermediate motion authentication result as the motion authentication process, and collates it with the motion authentication expected value held in advance as an expected value (step S130). The expected operation authentication value is information indicating whether the intermediate operation authentication result is the same or not. Whether to read the same or non-identical operation authentication expected value is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the main control unit 10 and the intermediate unit 20, and here, the information indicates the same. In this case, since the intermediate operation authentication result and the operation authentication expected value transmitted from the intermediate unit 20 are information indicating the same, both result in coincidence (step S130). When the intermediate operation authentication result matches the expected operation authentication value, the effect control unit 203 determines that the operation authentication of the main control unit 10 and the intermediate unit 20 has succeeded (step S130), and the individual authentication result in step S129. At the same time, it is determined that the authentication process of the pachinko gaming machine 1 has been successful (step S131). Thereafter, the effect control unit 203 selects the type of information to be read as the operation authentication expected value in the next authentication process based on the number of connections found in step S128. (Step S132). Here, since the number of connections = 3 and an odd number, the expected operation authentication value to be used next time is changed from the same to the non-identical. This is the flow of a series of selection processes.

  Let us move on to the explanation of the second processing. First, the main control unit 10 proceeds to the process of step S141, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S142. For example, the main control unit 10 determines that the current number of divisions is four. In step S142, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into four blocks (storage areas), and uses the program code stored in each block to 4 Two individual test values are generated (step S142), and the individual test values are subjected to encryption processing to generate individual authentication data (step S143).

  Next, the main control unit 10 selects the type of operation inspection value used for generating operation authentication data, and acquires the selected type of operation inspection value from the operation inspection value memory (step S144). It is an operation inspection value of either type of function number or number of times of authentication, and is determined at the time of the process related to the previous authentication. Here, it is the number of times of authentication. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, generates operation authentication data (step S145), generates a control signal with authentication data together with the individual authentication data, 20 (step S146). Thereafter, the main control unit 10 selects the type of the operation inspection value used for generating the operation authentication data in the next authentication process based on the number of divisions determined in step S141 (step S147). Here, since the number of divisions = 4 and an even number, the type of the operation inspection value to be used next time continues with the number of authentications. Then, the value of the authentication count is updated by adding 1 to the value of the authentication count, which is one of the operation inspection values (step S148).

  Next, processing in the intermediate unit 20 will be described. When the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S149), the intermediate unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and performs the operation inspection from the operation authentication data. A value is extracted (step S150).

  Next, the intermediate unit 20 collates the operation inspection value with the number of authentications held in advance (step S151). In this case, since the type of the operation inspection value transmitted from the main control unit 10 is the number of times of authentication, both are the same (step S151). Therefore, since the operation inspection value is not identical to the function number authentication expected value (intermediate operation authentication expected value) that matches the function number, the intermediate unit 20 generates an intermediate operation authentication result indicating non-identity, and this is the main control. Together with the individual authentication data transmitted from the unit 10, intermediate authentication information indicating non-identity is generated (step S152), and a control signal with intermediate authentication information including the intermediate authentication information is transmitted to the effect control unit 203 ( Step S153). Then, the intermediate unit 20 adds +1 to the value of the number of authentications and updates the value of the number of authentications (step S154).

  Next, processing in the effect control unit 203 will be described. When receiving the control signal with intermediate authentication information transmitted from the intermediate unit 20 (step S155), the effect control unit 203 extracts the individual authentication data and the intermediate operation authentication result from the control signal with intermediate authentication information, and the individual authentication data. The individual test value is extracted from (step S156). Then, the effect control unit 203 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S157). Thereafter, the combined result is collated with the individual authentication expected value held in advance, and if it matches the individual authentication expected value, the effect control unit 203 determines that the individual authentication of the main control unit 10 has been successful (step S158). Here, when the combination processing is performed using the four individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 4.

  Next, the effect control unit 203 refers to the extracted intermediate motion authentication result as the motion authentication process, and collates with the motion authentication expected value held in advance as an expected value (step S159). Whether to read the same or non-identical operation authentication expected value is determined at the time of the process related to the previous authentication. Here, it is information indicating non-identity. This time, since the intermediate operation authentication result and the operation authentication expected value transmitted from the intermediate unit 20 are information indicating non-identity, both result in coincidence (step S159). When the intermediate operation authentication result matches the expected operation authentication value, the effect control unit 203 determines that the operation authentication of the main control unit 10 and the intermediate unit 20 has succeeded (step S159), and the individual authentication result in step S158 In addition, it is determined that the authentication process of the pachinko gaming machine 1 is successful (step S160). Thereafter, the effect control unit 203 selects the type of information to be read as the operation authentication expected value in the next authentication-related process, based on the number of connections found in step S146. (Step S161). Here, since the number of connections = 4 and an even number, the type of expected operation authentication value to be used next time continues to be non-identical. This is the flow of a series of selection processes.

  Turning to the description of the third process. First, the main control unit 10 proceeds to the process of step S171, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S172. For example, the main control unit 10 determines that the current number of divisions is five. In step S172, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into five blocks (storage areas), and uses the program code stored in each block. Two individual test values are generated (step S172), and the individual test values are subjected to encryption processing to generate individual authentication data (step S173).

  Next, the main control unit 10 selects a type of operation inspection value used for generating operation authentication data, and acquires the selected type of operation inspection value from the operation inspection value memory (step S174). It is an operation inspection value of either type of function number or number of times of authentication, and is determined at the time of the process related to the previous authentication. Here, it is the number of times of authentication. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, generates operation authentication data (step S175), generates a control signal with authentication data together with the individual authentication data, 20 (step S176). Thereafter, based on the number of divisions determined in step S171, the main control unit 10 selects the type of operation inspection value used for generating operation authentication data in the next authentication process (step S177). Here, since the number of divisions = 5 and an odd number, the type of the operation inspection value to be used next time is changed from the number of authentications to the function number. Then, the value of the authentication count is updated by adding 1 to the value of the authentication count that is one of the operation inspection values (step S178).

  Next, processing in the intermediate unit 20 will be described. When the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S179), the intermediate unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and performs the operation inspection from the operation authentication data. A value is extracted (step S180).

  Next, the intermediate unit 20 collates the operation inspection value with the number of authentications held in advance (step S181). In this case, since the type of the operation inspection value transmitted from the main control unit 10 is the number of authentications, both are the same (step S181). Therefore, since the operation inspection value is not identical to the function number authentication expected value (intermediate operation authentication expected value) that matches the function number, the intermediate unit 20 generates an intermediate operation authentication result indicating non-identity, and this is the main control. Together with the individual authentication data transmitted from the unit 10, intermediate authentication information indicating non-identity is generated (step S182), and a control signal with intermediate authentication information including the intermediate authentication information is transmitted to the effect control unit 203 ( Step S183). Then, the intermediate unit 20 adds +1 to the value of the number of authentications and updates the value of the number of authentications (Step S184).

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with intermediate authentication information transmitted from the intermediate unit 20 (step S185), the production control unit 203 extracts the individual authentication data and the intermediate operation authentication result from the control signal with intermediate authentication information, and the individual authentication data. The individual test value is extracted from (step S186). And the production | generation control part 203 performs a joint process using the same half group calculation as the main control part 10 with respect to the extracted individual test | inspection value as an individual authentication process (step S187). Thereafter, the combined result is compared with the individual authentication expected value held in advance, and when the result matches the individual authentication expected value, the effect control unit 203 determines that the individual authentication of the main control unit 10 has been successful (step S188). Here, when combining processing is performed using five individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 5.

  Next, the effect control unit 203 refers to the extracted intermediate motion authentication result as the motion authentication process, and collates it with the motion authentication expected value held in advance as an expected value (step S189). Whether to read the same or non-identical operation authentication expected value is determined at the time of the process related to the previous authentication. Here, it is information indicating non-identity. This time, since the intermediate operation authentication result and the operation authentication expected value transmitted from the intermediate unit 20 are information indicating non-identity, both result in coincidence (step S189). When the intermediate operation authentication result matches the expected operation authentication value, the effect control unit 203 determines that the operation authentication of the main control unit 10 and the intermediate unit 20 has succeeded (step S189), and the individual authentication result in step S187 At the same time, it is determined that the authentication process of the pachinko gaming machine 1 is successful (step S190). Thereafter, the effect control unit 203 selects the type of information to be read as the operation authentication expected value in the next authentication-related process, based on the number of connections determined in step S187. (Step S191). Here, since the number of connections = 5 and an odd number, the type of expected operation authentication value to be used next time is changed from non-identical to the same. The above is the flow of a series of selection processes.

  The effect control unit 203 may perform the individual authentication process using the individual authentication data not when the individual authentication data is received but when the plurality of individual authentication data are received. In this case, for example, when the presentation control unit 203 receives the first individual authentication data together with the first control command data and the first associated data of the first control command, the control command is not performed and the control command is not performed. The processing based on the first control command data and the first associated data is performed. Then, when the presentation control unit 203 receives the second individual authentication data together with the second control command data of the second control command and the second accompanying data, the second control command data of the second control command Before performing the process based on the second associated data, the individual authentication process using the first individual authentication data is performed. At this time, the effect control unit 203 may perform the individual authentication process using both the first individual authentication data and the second individual authentication data.

  Further, the intermediate unit 20 does not erase all the data in each memory every time the processing related to the authentication is completed, but the operation stored last in each memory, that is, the operation generated last in the main control unit 10 The inspection value may be stored without being erased, and other data in the memory may be erased. Then, the intermediate operation authentication is performed using the operation inspection value generated at the end of the process related to the current authentication and the operation inspection value generated first in the process related to the next authentication. Thereby, since the continuity of the operation of the pachinko gaming machine 1 can be authenticated between the process related to the current authentication and the process related to the next authentication, the authentication strength in the operation authentication can be improved.

  As described above, in the first embodiment, the main control unit 10 divides predetermined data (predetermined program code) stored in advance to generate individual test values, and is divided as processing related to operation authentication. On the basis of the number of pieces of data (number of divisions), the type of operation inspection value used for generating operation authentication data is selected. The intermediate unit 20 verifies whether or not the operation inspection value generated by the main control unit 10 is the same as the expected value of the operation inspection value (intermediate operation authentication expected value) stored in advance as processing related to operation authentication ( Intermediate operation authentication process). The production control unit 203 performs individual authentication using the individual test value, and as a process related to the operation authentication, the verification result in the intermediate unit 20 (intermediate motion authentication result) is stored in advance in the intermediate unit 20 as a verification result. It is determined whether or not the expected value (operation authentication expected value) matches (operation authentication processing). In addition, the effect control unit 203 changes the expected operation authentication value based on the number of individual test values (number of connections) that are targets of the half group calculation when the individual authentication is successful. The number of divisions is a value that only the main control unit 10 can know, and the number of connections is a value that the effect control unit 203 can know only after successful individual authentication. Therefore, the fraudster cannot know the switching timing of the operation inspection value used for generating the operation authentication data in the main control unit 10 and the expected value in the effect control unit 203. For this reason, it is possible to prevent an unauthorized person from generating an operation inspection value illegally, and to improve the authentication strength for the processing among the main control unit 10, the intermediate unit 20, and the production control unit 203, and Actions and malfunctions of gaming machines can be detected, and execution of unauthorized control commands resulting from these can be prevented.

  In the first embodiment, as the authentication process of the pachinko gaming machine 1, the production control unit performs individual authentication of the main control 10, and the intermediate unit 20 and the production control unit 203 perform operation authentication. Therefore, in addition to the malfunction of the pachinko gaming machine 1 due to the above-mentioned fraudulent act on the main control unit 10 and noise, the fraudulent act and malfunction on the intermediate unit 20 can be detected. For example, even if an unauthorized control unit equipped with a signal switching circuit or the like is interposed between the intermediate unit 20 and the effect control unit 203, the unauthorized control unit is not limited to the effect control unit 203 based on the number of connections. Since it is not possible to know the switching timing of the operation authentication expected value at the production control unit 203, the fraudulent act can be detected by the effect control unit 203, and the security strength of the pachinko gaming machine 1 as a whole can be improved.

  In particular, in the first embodiment, as the operation authentication process in the intermediate unit 20 and the effect control unit 203, the intermediate unit 20 uses the operation test value generated by the main control unit 10 in the process related to the authentication this time. It is checked whether or not the stored operation inspection value is the same as the expected value (intermediate operation authentication expected value) (intermediate operation authentication). Then, the effect control unit 203 predicts whether the matching result (intermediate motion authentication result) transmitted from the intermediate unit 20 in the current authentication process is the same or non-identical matching result (motion authentication). (Expected value) is held, and it is determined whether or not the received collation result matches (operation authentication). Therefore, even if the operation authentication is successful, the information on the collation result transmitted from the intermediate unit 20 to the effect control unit 203 can include two types of information that are the same or non-identical. Further, whether the same or non-identical collation information is transmitted depends on the number of divisions that only the main control unit 10 can know. For this reason, a fraudster who tries to illegally steal a data signal transmitted / received between the intermediate unit 20 and the production control unit 203 has the same collation result which is the same or non-identical in the process related to the authentication. I can't know. Therefore, an unauthorized person can be disturbed and the authentication strength for the process between the intermediate unit 20 and the effect control unit 203 can be improved.

  In the first embodiment, as authentication processing of the pachinko gaming machine 1, individual authentication is performed by the effect control unit 203, and operation authentication is performed by the intermediate unit 20 and the effect control unit 203. In other words, since the intermediate unit 20 executes a part of the authentication process, it is possible to suppress an increase in the processing load of the CPU constituting the effect control unit 203. For this reason, the processing speed of the production | presentation control part 203 falls, and generation | occurrence | production of problems, such as the display for production | generation not being performed smoothly, can be prevented.

  Furthermore, in this Embodiment 1, since the intermediate | middle part 20 is provided between the main control part 10 and the production | presentation control part 203, between CPU10a which comprises the main control part 10, and CPU203a which comprises the production | generation control part 203 The intermediate unit 20 can absorb the difference in processing capacity between them, and the difference in storage capacity between the ROM 10b and RAM 10c constituting the main control unit 10 and the ROM 203b and RAM 203c constituting the effect control unit 203. Thereby, despite the difference in processing capacity and storage capacity between the main control unit 10 and the effect control unit 203, the security level between the main control unit 10 and the effect control unit 203 can be maintained. it can.

  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 are the processing capacity of the CPU 203 a constituting the effect control unit 203 and the ROM 203 b constituting the effect control unit 203. When there is a margin in comparison with the storage capacity of the RAM 203c, the main control unit 10 transmits authentication data obtained by performing complex or advanced encryption processing on each inspection value to the intermediate unit 20, and the intermediate unit 20 performs a process related to authentication using the received authentication data, and performs comparatively simple or low-level encryption processing on the obtained result and the like to generate intermediate authentication information. Send. And the production | presentation control part 203 performs the process regarding authentication using intermediate | middle authentication information. With this configuration, the pachinko gaming machine 1 can maintain a high security level without adopting a complicated or advanced decoding method in the effect control unit 203.

  Further, the processing capacity of the CPU 203a constituting the effect control unit 203 and the storage capacity of the ROM 203b and RAM 203b constituting the effect control unit 203 are the processing ability of the CPU 10a constituting the main control unit 10 and the ROM 10b constituting the main control unit 10. When there is a margin in comparison with the storage capacity of the RAM 10c, the main control unit 10 uses the inspection data as the authentication data as it is, or the authentication data obtained by performing relatively simple or low-level encryption processing on the intermediate unit 20 The intermediate unit 20 performs processing related to authentication using the received authentication data, performs complex or advanced cryptographic processing on the obtained result and the like, generates intermediate authentication information, and performs production control. To the unit 203. And the production | presentation control part 203 performs the process regarding authentication using intermediate | middle authentication information. With this configuration, the pachinko gaming machine 1 can maintain a high security level without adopting a complicated or advanced encryption method in the main control unit 10.

  This is not only the case where there is a difference in the processing capacity of the CPUs 10a and 203a constituting the main control unit 10 and the effect control unit 203, and the storage capacity of the ROMs 10b and 203b and the RAMs 10c and 203c, respectively. Although there is no significant difference, when the CPU 10a constituting the main control unit 10 or the CPU 203a constituting the effect control unit 203 changes all or a part of one of the programs to be executed (version upgrade, etc.) The same applies to a case where a formal difference occurs between the main control unit 10 and the effect control unit 203 in a data structure such as a value or intermediate authentication information.

<< Embodiment 2 >>
Hereinafter, the pachinko gaming machine 1 according to the second embodiment of the present invention will be described. The pachinko gaming machine 1 according to the second embodiment is different from the pachinko gaming machine 1 according to the first embodiment in the processing related to authentication in the intermediate unit 20 and the peripheral unit 30 (production control unit 203). Specifically, in the first embodiment, the intermediate unit 20 performs intermediate operation authentication, and the peripheral unit 30 (production control unit 203) performs individual authentication and final operation authentication. In the second form, individual authentication is performed by the intermediate unit 20, and operation authentication is performed by the peripheral unit 30 (the effect control unit 203). The points other than this are basically the same as the pachinko gaming machine 1 of the first embodiment, including the processing related to authentication in the main control unit 10. Hereinafter, the same members as those in the pachinko gaming machine according to the first embodiment are denoted by the same reference numerals, detailed description thereof will be omitted, and different points will be mainly described.

  The intermediate unit 20 includes an expected value storage unit 21 and an intermediate authentication unit 22. The expected value storage means 21 stores in advance an operation value obtained by performing a binary operation using predetermined data stored in the data storage means 11 constituting the main control unit 10 as an individual authentication expected value. Yes. The intermediate authentication unit 22 uses the result of individual authentication using the individual authentication data transmitted from the main control unit 10, the operation authentication data, and the switching information described later, to perform individual authentication and operation authentication in the peripheral unit 30. Intermediate authentication information used when making a final authentication decision from both sides is generated.

  Specifically, the intermediate authentication unit 22 first performs individual authentication using the individual authentication data transmitted from the main control unit 10. More specifically, an individual test value is extracted from the individual authentication data added to the control command and transmitted from the main control unit 10, and the same combination rule as that of the main control unit 10 is satisfied for the extracted individual test value. It is determined whether or not the individual authentication is successful based on whether or not the calculation result obtained by performing the binary operation matches the individual authentication expected value stored in the expected value storage unit 21. Further, the intermediate authentication means 22 determines the type of expected action authentication value to be used in the next action authentication performed by the effect control unit 203 based on the number of individual test values (number of connections) when the individual authentication is successful. Information about whether or not to switch from the expected operation authentication value used in the current operation authentication (hereinafter referred to as switching information) is generated.

  Thereafter, the intermediate unit 20 combines the individual authentication result, the switching information, and the operation authentication data transmitted from the main control unit 10 as intermediate authentication information, adds it to the control command, and transmits it to the peripheral unit 30.

  On the other hand, the peripheral unit 30 includes an expected value storage unit 31 and an authentication unit 32. The expected value storage unit 31 stores an operation authentication expected value in advance for each type of operation inspection value generated by the main control unit 10. The authentication unit 32 performs the operation authentication using the operation authentication data included in the intermediate authentication information transmitted from the intermediate unit 20, and combines the individual authentication result included in the intermediate authentication information with the individual authentication and the operation authentication. The authenticity of the final pachinko gaming machine 1 is authenticated from both sides.

  Specifically, the authentication unit 32 extracts an operation inspection value from the operation authentication data transmitted from the intermediate unit 20 and confirms whether the extracted operation inspection value indicates the continuity of the operation of the main control unit 10. In addition, it is determined whether or not the operation authentication is successful based on whether or not the operation authentication expected value stored in the expected value storage unit 31 matches the operation inspection value. Further, the authentication unit 32 selects the type of expected operation authentication value to be used in the next operation authentication based on the switching information transmitted from the intermediate unit 20.

  Thereafter, when both the individual authentication result included in the intermediate authentication information transmitted from the intermediate unit 20 and the operation authentication result in the authentication unit 32 are successful, the peripheral unit 30 authenticates the pachinko gaming machine 1 The authentication is performed and processing according to the authentication result is performed.

<Intermediate part>
Hereinafter, the processing related to authentication in the intermediate unit 20 will be described in detail. Since other than that is the same as that of Embodiment 1, description is abbreviate | omitted.
[1] Reception of control signal The intermediate unit 20 receives from the main control unit 10 a normal control signal consisting only of control command data and accompanying data, or individual authentication data and operation authentication data in addition to control command data and accompanying data. The control signal with authentication data is received. In addition, the intermediate | middle part 20 transmits to the production | presentation control part 203 as it is, when a normal control signal is received.
[2] Extraction of individual authentication data and operation authentication data The intermediate unit 20 extracts individual authentication data and operation authentication data from the control signal with authentication data. Next, the intermediate unit 20 extracts individual test values from the extracted individual authentication data, stores them in the individual test value memory, which is a predetermined storage area of the RAM 20c, and stores the extracted operation authentication data in the predetermined storage of the RAM 20c. The data is stored in the operation test value memory, which is an area.

[3] Individual authentication The intermediate unit 20 performs individual group authentication on all individual test values stored in the individual test value memory in the order shown below, thereby performing individual authentication of the main control unit 10. Process.
The {1} intermediate unit 20 performs a semigroup operation using all the individual test values stored in the individual test value memory.
{2} The intermediate unit 20 reads the expected individual authentication value stored in advance from a predetermined storage area of the ROM 20b.

The {3} intermediate unit 20 determines whether or not the combined result in the process {1} matches the expected individual authentication value read in the process {2}.
The intermediate unit 20 determines that the individual authentication is successful when the combined result matches the expected individual authentication value. Further, the intermediate unit 20 determines that the individual authentication has not been successful if the combined result and the individual authentication expected value do not match. When individual authentication is successful, the number of connections and the number of divisions naturally match.

When the individual authentication is successful in the processing of {4} {3}, the intermediate unit 20 generates an individual authentication result indicating that the individual authentication is successful.
If the individual authentication is not successful in the process of {5} {3}, the intermediate unit 20 determines whether or not the number of individual authentication data received from the main control unit 10 is a predetermined number or more. The predetermined number is an arbitrary number within the range not less than the current number of connections (number of divisions) and not more than the number (maximum number of divisions) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided. is there.
{5-1} When the number of received individual authentication data is less than the predetermined number, the intermediate unit 20 determines that the individual authentication is not yet possible and can replace the individual authentication result with the authentication intermediate data, for example, An arbitrary value (for example, all 0 or all 1) having the same data length as the data length of the individual authentication result is generated.
{5-2} If the number of received individual authentication data is equal to or greater than the predetermined number, the intermediate unit 20 determines that the individual authentication has not been successful, and generates an individual authentication result indicating that the individual authentication has not been successful. To do.

[4] Generation of Switching Information The intermediate unit 20 generates switching information for the expected operation authentication value held by the effect control unit 203 according to a predetermined agreement based on the number of connections when individual authentication is successful. The switching information is information indicating how to change the type of expected operation authentication value used in the next operation authentication performed by the production control unit 203 from the expected operation authentication value used in the current operation authentication. It is. Here, the predetermined agreement is the same as that in which the main control unit 10 selects the type of the operation inspection value used for generating the operation authentication data, as in the first embodiment. That is, when the number of couplings is an odd number, the switching information for changing the type of expected operation authentication value is generated. When the number of couplings is an even number, the switching information for maintaining the type of expected operation authentication value currently used is generated. To do. Note that a value obtained by performing a predetermined operation on the switching information and encrypting it may be used, or instead of the switching information, using a value obtained by performing a predetermined operation on the coupling number itself or the coupling number. Also good.

[5] Generation of intermediate authentication information The intermediate unit 20 includes the operation authentication data extracted in the process [2], the individual authentication result obtained in the process [3], and the switching information obtained in the process [4]. Alternatively, intermediate authentication information is generated by using the same encryption processing as that performed when the main control unit 10 generates authentication data. In the process [3], the intermediate unit 20 generates intermediate authentication information indicating that the individual authentication is successful, and generates a result indicating that the individual authentication is not successful. In this case, intermediate authentication information indicating that is generated.

[6] Generation of control signal with intermediate authentication information The intermediate unit 20 adds the intermediate authentication information to a normal control signal including control command data and accompanying data, and generates a control signal with intermediate authentication information.

[7] Transmission of control signal with intermediate authentication information The intermediate unit 20 transmits a control signal with intermediate authentication information to the effect control unit 203 and stores each data stored in the individual test value memory and the motion test value memory. Erase. The means for storing the individual authentication expected value in advance and the means for executing the individual authentication can correspond to, for example, the expected value storage means 21 and the intermediate authentication means 22 shown in FIG. Also, the data format of the control signal with intermediate authentication information can be the same as that in the first embodiment, and thus the description thereof is omitted.

<Production control unit>
Hereinafter, a case where the effect control unit 203 which is one of the peripheral units 30 performs processing related to authentication will be described in detail. Since other than that is the same as that of Embodiment 1, description is abbreviate | omitted.
[1] Reception of control signal The effect control unit 203 determines whether the control signal transmitted from the intermediate unit 20 is a normal control signal consisting only of control command data and accompanying data, or in addition to the control command data and accompanying data. It is determined whether it is a control signal with intermediate authentication information to which authentication information is added. When the received control signal is a normal control signal, the effect control unit 203 performs a process related to the effect based on the control command data and the accompanying data, and ends the process related to authentication. On the other hand, when the received control signal is a control signal with intermediate authentication information, the effect control unit 203 executes the following processes [2] to [4] on the assumption that the process related to authentication is continued.

[2] Extraction of individual authentication result and operation authentication data The effect control unit 203 extracts an individual authentication result and operation authentication data from the control signal with intermediate authentication information. Next, the effect control unit 203 stores the extracted individual authentication result in an individual test value memory which is a predetermined storage area of the RAM 203c. In addition, the effect control unit 203 extracts the operation inspection value by applying the decryption process corresponding to the encryption process used when generating the operation authentication data to the extracted operation authentication data, and the operation inspection which is a predetermined storage area of the RAM 203c. Store in the value memory. When the individual authentication result is encrypted in the intermediate unit 20, the effect control unit 203 performs a decryption process corresponding to the applied encryption process on the individual authentication result.

[3] Operation Authentication The effect control unit 203 performs operation authentication on the control command output of the main control unit 10 in the following order, using the operation inspection value stored in the operation inspection value memory.
Operation authentication using {1} operation inspection value
{1-1} The production control unit 203 reads the operation inspection value stored in the operation inspection value memory. If there are a plurality of operation inspection values, they are read in correspondence with the order of output.
{1-2} The effect control unit 203 reads the expected operation authentication value stored in a predetermined storage area of the RAM 30c. In the second embodiment, the type of expected operation authentication value to be read is either a function number or the number of authentications. Note that the type of expected operation authentication value used for the first operation authentication is a function number.

{1-3} The effect control unit 203 determines whether or not the operation authentication data read out in the process {1-1} matches the expected value for operation authentication read out in the process {1-2}. Judgment (collation process).
The effect control unit 203 determines that the operation authentication is successful when the operation inspection value matches the operation authentication expected value. In addition, when the motion inspection value and the motion authentication expected value do not match, the effect control unit 203 determines that the motion authentication has not been successful.

When the operation authentication is successful in the process {1-4} {1-3}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is successful.
If the operation authentication is not successful in the processing of {1-5} {1-3}, the effect control unit 203 generates an operation authentication result indicating that the operation authentication is not successful.
In the second embodiment, similar to the first embodiment, the type of the operation inspection value used for the first generation of the operation authentication data in the main control unit 10 and the expected operation authentication value read in the first time in the effect control unit 203 Since both types correspond to function numbers, the operation authentication is successful.
{1-6} The production control unit 203 selects the type of expected operation authentication value to be read in the next authentication process according to the switching information transmitted from the intermediate unit 20. The switching information in the second embodiment changes the type of expected operation authentication value when the number of connections is odd, and continues the type of expected operation authentication value currently used when the number of connections is even. .
{1-7} Production control unit 203 updates the value of the expected operation authentication value corresponding to the number of authentications. Specifically, the effect control unit 203 adds +1 to the value of the expected value for operation authentication indicating the number of authentications among the expected value for operation authentication stored in the predetermined storage area of the RAM 30c, and sets the new number of authentications. A value, that is, an expected value for operation authentication is generated, and the expected value for operation authentication is stored in a predetermined storage area of the RAM 30c.

[4] Process based on authentication result The production control unit 203 uses the individual authentication result obtained in the process [2] and the operation authentication result obtained in the process [3] to authenticate the pachinko gaming machine 1. The gender is authenticated from both the individual authentication and the operation authentication, and the final authentication judgment is made. When both the individual authentication result obtained in the process [2] and the operation authentication result obtained in the process [3] are results indicating successful authentication, the effect control unit 203 determines that the intermediate authentication information A process based on the control command data and accompanying data included in the attached control signal is executed, and each data stored in the individual test value memory and the operation test value memory is erased, and the process related to authentication is terminated. On the other hand, if either the individual authentication result obtained by the process [2] or the operation authentication result obtained by the operation authentication which is the process [3] is a result indicating that the authentication is unsuccessful, the control command Discard the data and accompanying data, perform processing such as notification that fraud has been detected, erase each data stored in the individual test value memory and the operation test value memory, and end the process related to authentication To do. Note that the above-described means for storing the expected operation authentication value and the means for executing the operation authentication can correspond to, for example, the expected value storage means 31 and the authentication means 32 shown in FIG.

  Next, processing related to authentication by the intermediate unit 20 will be described. FIG. 17 is a flowchart illustrating an example of a processing procedure related to authentication by the intermediate unit 20. First, the intermediate unit 20 determines whether or not a control signal as shown in FIG. 5 transmitted from the main control unit 10 has been received (step S201). If the determination result is “NO”, the intermediate unit 20 repeats the determination. And if the control signal transmitted from the main control part 10 is received (step S201: YES), the intermediate part 20 will progress to step S202.

  In step S202, the intermediate unit 20 determines whether each authentication data is included in the received control signal. If each authentication data is included in the received control signal (step S202: YES), the intermediate unit 20 proceeds to step S203. Here, the determination of whether or not each authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, This is done by determining whether or not any bit constituting ID or identification data (not shown) provided separately indicates that each authentication data is included. In the process of step S202, the intermediate unit 20 does not determine whether or not each authentication data is included in the received control signal, but the control command data included in the control signal is a control of a predetermined control command. It may be determined whether it is command data.

  When each authentication data is included in the received control signal (step S202: YES), that is, when the received control signal is a control signal with authentication data, the intermediate unit 20 is included in the received control signal with authentication data. The individual authentication data is extracted and decrypted to extract the individual test value, and the operation authentication data is extracted (step S203). The intermediate unit 20 stores the extracted individual test value in the individual test value memory and the extracted operation authentication data in the operation test value memory, and proceeds to step S204.

  Next, the intermediate unit 20 performs a semigroup operation (joining process) on all the individual test values in the individual test value memory as the individual authentication process (step S204). If there is one test value in the individual test value memory, the process directly proceeds to step S205 without performing the combining process. Then, the intermediate unit 20 collates the operation result (joining result) of the joining process with the held individual authentication expected value, and determines whether or not the joining result matches the expected individual authentication value (step) S205). When the combined result and the individual authentication expected value match (step S205: YES), the intermediate unit 20 determines that the individual authentication of the main control unit 10 is successful, and displays the individual authentication result indicating that the individual authentication is successful. Generate (step S206).

  Subsequently, the intermediate unit 20 determines whether or not the number of connections determined in step S204 is a predetermined value (step S207). The predetermined value is an odd number as in the first embodiment. When the number of connections is a predetermined value (step S207: YES), the intermediate unit 20 displays switching information indicating that the type of operation authentication expected value used in the next operation authentication performed by the effect control unit 203 is changed. Generate (step S208), and proceed to step S210. On the other hand, when the number of connections is not a predetermined value (step S207: NO), switching information indicating that the type of operation authentication expected value used in the next operation authentication performed in the effect control unit 203 is continued without being changed. Generate (step S209), and proceed to step S210.

  On the other hand, if the combined result does not match the expected individual authentication value in step S205 (step S205: NO), the intermediate unit 20 proceeds to step S201 until receiving a predetermined number or more of individual authentication data (step S212: NO). The process of receiving the individual authentication data and combining the individual test values is repeated. After receiving a predetermined number or more of individual authentication data (step S212: YES), the intermediate unit 20 determines that the individual authentication of the main control unit 10 is unsuccessful and generates an individual authentication result indicating that the individual authentication is unsuccessful. (Step S213), the process proceeds to Step S210.

  The intermediate unit 20 generates intermediate authentication information by combining the generated individual authentication result, switching information indicating change or continuation, and operation authentication data stored in the operation inspection value memory (step S210). Thereafter, the intermediate unit 20 generates a control signal with intermediate authentication information including the generated intermediate authentication information, transmits it to the effect control unit 203 (step S211), and stores it in the individual test value memory and the motion test value memory. The stored data is erased, and the series of processing ends.

  If each authentication data is not included in the received control signal in step S202, that is, if the received control signal is a normal control signal (step S202: NO), the intermediate unit 20 performs the authentication process. Without performing, the received normal control signal is transmitted as it is to the effect control unit 203 (step S214), and the series of processes is terminated.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 18 is a flowchart illustrating an example of a processing procedure related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether a control signal is received from the intermediate unit 20 (step S221). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the intermediate part 20, the judgment result of step S221 will be "YES", and the production | presentation control part 203 will progress to step S222.

  In step S222, the effect control unit 203 determines whether intermediate authentication information is included in the received control signal. When the determination result of step S222 is “YES”, that is, when the intermediate authentication information is included in the received control signal, the effect control unit 203 proceeds to step S223. Here, whether or not the intermediate authentication information is included in the control signal is determined by, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, It is determined whether or not any bit constituting ID or separately provided identification data (not shown) indicates that intermediate authentication information is included, or a control command included in a control signal It may be determined whether the data is control command data of a predetermined control command set in advance for performing the authentication process.

  When the received control signal includes intermediate authentication information (step S222: YES), that is, when the received control signal is a control signal with intermediate authentication information, the effect control unit 203 receives the received control with intermediate authentication information. The individual authentication result and the switching information included in the signal are extracted, the operation authentication data is extracted and the decryption process is performed to extract the operation inspection value (step S223). The effect control unit 203 stores the extracted individual authentication result in the individual test value memory, and stores the extracted switching information and the operation test value in the operation test value memory, and proceeds to step S224. In step S222, if the received control signal does not include intermediate authentication information, that is, if the received control signal is a normal control signal (step S222: NO), the effect control unit 203 performs the authentication process. It progresses to step S232, without performing.

  Next, the effect control unit 203 confirms the individual authentication result stored in the individual test value memory, and determines whether the individual authentication performed by the intermediate unit 20 is successful (step S224). When the individual authentication result is a result indicating success (step S224: YES), the effect control unit 203 determines that the individual authentication in the intermediate unit 20 is successful, and proceeds to step S225. When the individual authentication result is not a result indicating success (step S224: NO), the production control unit 203 makes the individual authentication in the intermediate unit 20 unsuccessful, and the authentication process of the current pachinko gaming machine 1 is not successful. (Step S233), the process proceeds to step S234.

  In step S225, the effect control unit 203 reads the motion authentication expected value previously held as the expected value, and determines whether or not the motion inspection value matches the motion authentication expected value (step S225). When the motion inspection value matches the motion authentication expected value (step S225: YES), the effect control unit 203 determines that the motion authentication is successful (step S226), and combines the individual authentication result confirmed in step S224. Then, it is determined that the authentication process of the pachinko gaming machine 1 has been successful (step S227).

  Subsequently, the effect control unit 203 refers to the switching information stored in the motion inspection value memory (Step S228), and the switching information is information for changing the type of the expected motion authentication value used in the next motion authentication. Whether or not (step S229). When the switching information indicates a change (step S199: YES), the effect control unit 203 changes the type of expected operation authentication value used in the next operation authentication (step S230), and proceeds to step S201. When the switching information does not indicate a change (step S229: NO), the effect control unit 203 does not change the type of expected operation authentication value used in the next operation authentication, and proceeds to step S231. In step S231, the effect control unit 203 updates the value of the expected value for operation authentication indicating the number of authentications among the expected values for operation authentication (step S231). Specifically, an expected value for operation authentication is generated by adding +1 to the expected value for operation authentication indicating the number of times of authentication, and this expected value for operation authentication is stored in a predetermined storage area of the RAM 30c. Next, the data stored in the individual test value memory and the operation test value memory are erased and a process based on the control command data and the accompanying data is performed (step S232), and the series of processes is terminated.

  On the other hand, if the motion inspection value does not match the motion authentication expected value in step S225 (step S225: NO), the effect control unit 203 makes the motion authentication unsuccessful and the authentication process of the current pachinko gaming machine 1 succeeds. It is determined that there is not (step S233), and the process proceeds to step S234. In step S234, the effect control unit 203 interrupts the processing based on the control command data and the accompanying data, discards the data, and sends a notification signal for notifying the illegal act to the symbol display unit 104 and the lamp control unit 205. Or after transmitting to the center control apparatus etc. which manage the pachinko game machine 1, a series of processes are complete | finished. In the process of step S234, the effect control unit 203 may perform only one of data discarding and notification.

  Next, of the processes shown in FIGS. 13, 17, and 18, in the change process of the operation inspection value used for generating the operation authentication data by the main control unit 10 and the change process of the expected operation authentication value by the effect control unit 203. A specific example will be described. FIG. 19 is a sequence diagram illustrating an example of the data flow among the main control unit 10, the intermediate unit 20, and the effect control unit 203.

  First, the main control unit 10 proceeds to the process of step S241, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S242. For example, the main control unit 10 determines that the current number of divisions is three. In step S242, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into three blocks (storage areas), and uses the program code stored in each block to 3 One individual test value is generated (Step S242), and the individual test value is subjected to encryption processing to generate individual authentication data (Step S243).

  Next, the main control unit 10 selects the type of the operation inspection value used for generating the operation authentication data, and acquires the selected type of operation inspection value from the operation inspection value memory (step S244). It is an operation inspection value of either type of function number or number of times of authentication, and is determined at the time of the process related to the previous authentication. Note that the type of the first operation inspection value is determined in advance between the intermediate unit 20 and the effect control unit 203, and is a function number here. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, generates operation authentication data (step S245), generates a control signal with authentication data together with the individual authentication data, 20 (step S246). Thereafter, based on the number of divisions determined in step S241, the main control unit 10 selects the type of operation inspection value used for generating operation authentication data in the next authentication process (step S247). Here, since the number of divisions = 3 and an odd number, the type of the operation inspection value to be used next time is changed from the function number to the number of times of authentication. Then, the value of the number of times of authentication is updated by adding 1 to the value of the number of times of authentication which is one of the operation inspection values (step S248).

  Next, processing in the intermediate unit 20 will be described. When the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S249), the intermediate unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and also performs the individual examination from the individual authentication data. A value is extracted (step S250). Then, the intermediate unit 20 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S251). Thereafter, the combined result is compared with the expected individual authentication value held in advance, and if it matches the expected individual authentication value, the intermediate unit 20 determines that the individual authentication of the main control unit 10 is successful (step S252). Here, when combining processing is performed using three individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 3.

  Next, the intermediate unit 20 generates switching information for selecting the type of expected operation authentication value to be used in the next operation authentication performed by the effect control unit 203 based on the number of connections found in step S251 (step S253). ). Here, since the number of connections = 3 and an odd number, switching information indicating that the type of expected operation authentication value to be used next time is changed is generated. Then, the intermediate unit 20 generates the intermediate authentication information by combining the individual authentication result, the switching information, and the operation authentication data transmitted from the main control unit 10 (step S254), and the intermediate authentication including the intermediate authentication information The control signal with information is transmitted to the effect control unit 203 (step S255).

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with intermediate authentication information transmitted from the intermediate unit 20 (step S256), the production control unit 203 extracts the individual authentication result, the switching information, and the operation authentication data from the control signal with intermediate authentication information, and the operation. An operation inspection value is extracted from the authentication data (step S257). Then, when confirming that the individual authentication result indicates success, the effect control unit 203 collates the operation inspection value with the expected operation authentication value held in advance as the operation authentication process (step S258). Which type of operation authentication expected value to read, such as the function number or the number of authentication times, is determined at the time of the process related to the previous authentication. Note that the first time is determined in advance between the main control unit 10 and the intermediate unit 20, and is a function number here. In this case, both the operation inspection value and the operation authentication expected value used for generating the operation inspection value transmitted from the intermediate unit 20 indicate the function number, and thus both coincide with each other (step S258).

  Next, when the motion inspection value matches the motion authentication expected value, the effect control unit 203 determines that the motion authentication of the main control unit 10 and the intermediate unit 20 has succeeded (step S258), and the individual extracted in step S257. Together with the authentication result, it is determined that the authentication process of the pachinko gaming machine 1 is successful (step S259). Then, with reference to the switching information transmitted from the intermediate unit 20, it is determined whether or not the switching information is information for changing the type of expected operation authentication value used in the next operation authentication (step S260). This time, the type of operation authentication expected value is a function number, and the switching information indicating that the change has been received has been received. Here, the type of operation authentication expected value to be used next time is changed from the function number to the number of authentications (step S260). . Then, the effect control unit 203 adds +1 to the value of the expected operation authentication value corresponding to the number of authentications, and updates the expected operation authentication value (step S261). This is the flow of a series of selection processes.

  Let us move on to the explanation of the second processing. First, the main control unit 10 proceeds to the process of step S271, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S272. For example, the main control unit 10 determines that the current number of divisions is four. In step S272, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into four blocks (storage areas), and uses the program code stored in each block to 4 One individual test value is generated (step S272), and the individual test value is subjected to encryption processing to generate individual authentication data (step S273).

  Next, the main control unit 10 selects the type of operation inspection value used for generating the operation authentication data, and acquires the selected type of operation inspection value from the operation inspection value memory (step S274). It is an operation inspection value of either type of function number or number of times of authentication, and is determined at the time of the process related to the previous authentication. Here, it is the number of times of authentication. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, generates operation authentication data (step S275), generates a control signal with authentication data together with the individual authentication data, 20 (step S276). Thereafter, the main control unit 10 selects the type of the operation inspection value used for generating the operation authentication data in the next authentication-related process based on the number of divisions determined in step S271 (step S277). Here, since the number of divisions = 4 and an even number, the type of the operation inspection value to be used next time continues with the number of authentications. Then, the value of the authentication count is updated by adding 1 to the value of the authentication count that is one of the operation inspection values (step S278).

  Next, processing in the intermediate unit 20 will be described. When the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S279), the intermediate unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and also performs the individual examination from the individual authentication data. A value is extracted (step S280). Then, the intermediate unit 20 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S281). Thereafter, the combined result is collated with the expected individual authentication value held in advance, and if it matches the expected individual authentication value, the intermediate unit 20 determines that the individual authentication of the main control unit 10 has been successful (step S282). Here, when the combination processing is performed using the four individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 4.

  Next, the intermediate unit 20 generates switching information for selecting the type of expected operation authentication value to be used in the next operation authentication performed by the effect control unit 203 based on the number of connections found in step S281 (step S283). ). Here, since the number of connections = 4 and an even number, switching information indicating that the type of expected operation authentication value to be used next time is continued without being changed is generated. Then, the intermediate unit 20 generates intermediate authentication information by combining the individual authentication result, the switching information, and the operation authentication data transmitted from the main control unit 10 (step S284), and includes intermediate authentication information including the intermediate authentication information. The control signal with information is transmitted to the effect control unit 203 (step S285).

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with intermediate authentication information transmitted from the intermediate unit 20 (step S286), the effect control unit 203 extracts the individual authentication result, the switching information, and the operation authentication data from the control signal with intermediate authentication information, and the operation. An operation inspection value is extracted from the authentication data (step S287). Then, when confirming that the individual authentication result indicates success, the effect control unit 203 collates the operation inspection value with the expected operation authentication value held in advance as operation authentication processing (step S288). Which type of operation authentication expected value to read, such as the function number or the number of authentication times, is determined at the time of the process related to the previous authentication. Here, it is the number of times of authentication. In this case, since the operation inspection value and the operation authentication expected value used for generating the operation inspection value transmitted from the intermediate unit 20 indicate the number of times of authentication, the results coincide with each other (step S288).

  Next, when the motion inspection value matches the motion authentication expected value, the effect control unit 203 determines that the motion authentication of the main control unit 10 and the intermediate unit 20 has succeeded (step S288), and the individual extracted in step S287. Together with the authentication result, it is determined that the authentication process of the pachinko gaming machine 1 is successful (step S289). Then, the switching information transmitted from the intermediate unit 20 is referred to, and it is determined whether or not the switching information is information for changing the type of expected operation authentication value used in the next operation authentication (step S290). This time, the expected operation authentication value is the number of times of authentication, and the switching information indicating that continuation has been received, the type of expected operation authentication value to be used next time continues as the number of times of authentication (step S290). Then, the effect control unit 203 adds 1 to the value of the expected operation authentication value corresponding to the number of times of authentication, and updates the expected operation authentication value (step S291). This is the flow of a series of selection processes.

  Turning to the description of the third process. First, the main control unit 10 proceeds to the process of step S301, determines the number of divisions used for the current individual authentication process by an arbitrary method, and then proceeds to step S302. For example, the main control unit 10 determines that the current number of divisions is five. In step S302, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into five blocks (storage areas), and uses the program code stored in each block. One individual test value is generated (step S302), and the individual test value is encrypted to generate individual authentication data (step S303).

  Next, the main control unit 10 selects the type of the operation inspection value used for generating the operation authentication data, and acquires the selected type of operation inspection value from the operation inspection value memory (step S304). It is an operation inspection value of either type of function number or number of times of authentication, and is determined at the time of the process related to the previous authentication. Here, it is the number of times of authentication. Then, the main control unit 10 performs an encryption process on the acquired operation inspection value, generates operation authentication data (step S305), generates a control signal with authentication data together with the individual authentication data, 20 (step S306). After that, the main control unit 10 selects the type of operation inspection value used for generating operation authentication data in the next authentication-related process based on the number of divisions determined in step S301 (step S307). Here, since the number of divisions = 5 and an odd number, the type of operation inspection value to be used next time is changed from the number of authentications to the function number. Then, the value of the authentication count is updated by adding 1 to the value of the authentication count that is one of the operation inspection values (step S308).

  Next, processing in the intermediate unit 20 will be described. When the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S309), the intermediate unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and also performs the individual examination from the individual authentication data. A value is extracted (step S310). Then, the intermediate unit 20 performs a combination process on the extracted individual test value using the same half group operation as that of the main control unit 10 as the individual authentication process (step S311). Thereafter, the combined result is compared with the individual authentication expected value held in advance, and if it matches the individual authentication expected value, the intermediate unit 20 determines that the individual authentication of the main control unit 10 is successful (step S312). Here, when combining processing is performed using five individual test values, it matches with the individual authentication expected value, and it is found that the current number of connections = 5.

  Next, the intermediate unit 20 generates switching information for selecting the type of expected operation authentication value to be used in the next operation authentication performed by the effect control unit 203 based on the number of connections found in step S311 (step S313). ). Here, since the number of connections = 5 and an odd number, switching information indicating that the type of expected operation authentication value to be used next time is changed is generated. Then, the intermediate unit 20 generates intermediate authentication information by combining the individual authentication result, the switching information, and the operation authentication data transmitted from the main control unit 10 (step S314), and includes intermediate authentication information including the intermediate authentication information. The control signal with information is transmitted to the effect control unit 203 (step S315).

  Next, processing in the effect control unit 203 will be described. When the production control unit 203 receives the control signal with intermediate authentication information transmitted from the intermediate unit 20 (step S316), the production control unit 203 extracts the individual authentication result, the switching information, and the operation authentication data from the control signal with intermediate authentication information, and the operation. An operation inspection value is extracted from the authentication data (step S317). Then, when confirming that the individual authentication result indicates success, the effect control unit 203 collates the operation inspection value with the operation authentication expected value held in advance as the operation authentication process (step S318). It is an operation inspection value of either type of function number or number of times of authentication, and is determined at the time of the process related to the previous authentication. Here, it is the number of times of authentication. In this case, both the operation inspection value and the operation authentication expected value transmitted from the intermediate unit 20 indicate the number of authentications, and therefore both coincide with each other (step S318).

  Next, when the motion inspection value matches the motion authentication expected value, the effect control unit 203 determines that the motion authentication of the main control unit 10 and the intermediate unit 20 has succeeded (step S318), and the individual extracted in step S317. Together with the authentication result, it is determined that the authentication process of the pachinko gaming machine 1 is successful (step S319). Then, the switching information transmitted from the intermediate unit 20 is referred to, and it is determined whether or not the switching information is information for changing the type of expected operation authentication value used in the next operation authentication (step S320). This time, the type of operation authentication expected value is the number of times of authentication, and the switching information indicating that the change has been received has been received. Here, the type of operation authentication expected value to be used next time is changed from the number of times of authentication to the function number (step S320). . Then, the effect control unit 203 adds +1 to the value of the expected operation authentication value corresponding to the number of times of authentication, and updates the expected operation authentication value (step S321). The above is the flow of a series of selection processes.

As described above, in the pachinko gaming machine 1 according to the second embodiment, the intermediate unit 20 corresponds to the switching of the type of the operation inspection value in the main control unit 10 and the operation authentication expected value based on the number of connections. Switch. For example, the intermediate unit 20 switches the operation authentication expected value in response to switching of the type of the operation inspection value of the main control unit 10 when the number of couplings is an odd number, and the operation authentication used last time when the number of couplings is an even number. Continue to use the expected value. The number of divisions is a value known only by the main control unit 10, and the intermediate unit 20 can know the value as the number of couplings only when the authentication is successful. Therefore, the fraudster cannot know the number of divisions and the number of combinations, and cannot know the switching timing of the operation inspection value and the switching timing of the operation authentication expected value (switching of the authentication method). Thereby, it is possible to prevent an illegal operation person from generating an operation inspection value illegally. Further, this can improve the strength of the authentication process between the main control unit and the intermediate unit.
The pachinko gaming machine 1 according to the second embodiment is different from the pachinko gaming machine 1 according to the first embodiment in the processing related to authentication in the intermediate unit 20 and the peripheral unit 30 (the effect control unit 203). Individual authentication and operation authentication are performed by the peripheral unit 30 (production control unit 203), and the same effects as those of the first embodiment can be obtained.

<< Embodiment 3 >>
In the said Embodiment 1, 2, although the intermediate part 20 and the production | presentation control part 203 showed the example set as a separate hardware structure, it is not limited to this.
For example, with respect to the first embodiment, one CPU has the functions of the CPU 20a configuring the intermediate unit 20 and the function of the CPU 203a configuring the effect control unit 203, and the intermediate unit 20 is configured. The program code stored in the ROM 20b and other fixed data and the program code stored in the ROM 203b constituting the effect control unit 203 and other fixed data are stored in one ROM. Also good. In this case, transmission / reception of data between the intermediate unit 20 and the effect control unit 203 functions as, for example, a work area of the RAM 20c configuring the intermediate unit 20 and also functions as a work area of the RAM 203c configuring the effect control unit 203. In such a single RAM, it can be realized by copying data from one storage area to another storage area or rewriting an address to be referred to.

  However, in the above case, since one CPU has the functions of two CPUs, the processing load generally increases. Thus, for example, the processing of the intermediate unit 20 may be performed with a dual CPU configuration.

  Since the pachinko gaming machine 1 according to the third embodiment has the intermediate unit 20 and the effect control unit 203 configured by a single piece of software, in addition to the effects obtained in the first and second embodiments, the following effects can be obtained. can get.

1. Parallel development and information security improvement When the production control unit and the intermediate unit are separated and independent on the software configuration, it is possible to develop the production control unit and the intermediate unit individually in parallel, for example, The following effects can be obtained.

[1] Since the production control unit and the intermediate unit can be designed and developed at the same time, the product development period can be shortened compared to the case where parallel development is not possible.
[2] Since it is possible to take independent development systems for the production control unit and the intermediate unit, confidential business information (for example, an authentication processing method, etc.) when performing design and manufacturing verification of the production control unit and the intermediate unit. , Processing related to games, etc.) can be reduced out of the respective development system.

2. Ease of verification When the production control unit and the intermediate unit are separated and independent in terms of software configuration, it is possible to individually verify the production control unit and the intermediate unit. Therefore, as compared with the case where verification is performed for a case where the production control unit and the intermediate unit are not separated, each function is closed by a narrow function, so that verification can be performed in a short period of time with a small number of people.

3. Even if it is not possible to provide a CPU or dedicated integrated circuit separate from the effect control unit as hardware for authentication, an authentication function can be easily added by software.

4). Reduction of processing load of the production control unit When the authentication function implemented in the intermediate unit is implemented by software of the production control unit, the processing load of the production control unit increases. Therefore, it is conceivable to use a dual core CPU as the CPU constituting the production control unit. Since the processing load for realizing the authentication process can be distributed by using the dual core CPU, the authentication function is provided so as not to affect the existing game process of the production control unit as much as possible. The authentication function can be easily realized.

<< Other Embodiments >>
The specific configuration of the present invention is not limited to the above-described embodiments, and any design change or the like within a range not departing from the gist of the present invention is included in the present invention.
For example, in Embodiment 1, although the example which provides the intermediate | middle part 20 between the main control part 10 and the production | generation control part 203 was shown, it is not limited to this, Between the main control part 10 and the prize ball control part 204 An intermediate portion 20 may be provided between them. In this case, the prize ball control unit 204 is not provided with an informing means, but since bidirectional communication is possible between the main control unit 10 and the prize ball control unit 204, the authentication is unsuccessful. The prize ball control unit 204 may be configured to transmit data indicating that the authentication is unsuccessful to the main control unit 10 together with the control command data and accompanying data. Then, the main control unit 10 transmits the data indicating the unsuccessfulness to the effect control unit 203 via the intermediate unit 20, and the effect control unit 203 based on the data indicating the unsuccessful, Notify that fraud has occurred.
In the pachinko gaming machine 1 according to the first to third embodiments, the intermediate unit 20 includes a CPU, a ROM, a RAM, and the like, but is realized as an integrated circuit such as an LSI having the same function. You may do it.

  In the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10, the intermediate unit 20, and the peripheral unit 30 are configured to include at least separate CPUs, ROMs, RAMs, and the like, and the functions of the respective units are separate. However, the functions of each unit may be realized by a single middleware. This makes it possible to add an authentication function as a highly versatile middleware in the development of new models of gaming machines, facilitates horizontal deployment to other models, and requires only a small design change for each model. It can contribute to realization.

  In the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10 is generated by a random number generation circuit, a random number generation program, or the like as a predetermined data division method for generating individual test values. Although the value is determined as the number of divisions and predetermined data is divided into the determined number of divisions, the present invention is not limited to this. The main control unit 10 determines the amount of data constituting each data block for which individual test values are to be generated (hereinafter referred to as data amount), and the main control unit 10 stores predetermined data in a predetermined storage area. The data is divided by the determined amount of data. Then, the main control unit 10 performs a semi-group operation for each data block divided by the data amount, and generates individual test values for the number of divided data blocks for authenticating the main control unit 10. That is, the number of data blocks obtained by the division becomes the division number. As a method for determining the data amount, a method of referring to a value generated in another process of the main control unit 10 at a predetermined timing in addition to the random number generation circuit and the random number generation program and using the value as the data amount can be considered. .

  In this case, every time the main control unit 10 generates one individual test value, the main control unit 10 determines the amount of data used for the generation, and uses all of the predetermined data in the predetermined storage area of the main control unit 10, Until the generation of the individual test value is completed, the determination of the data amount and the generation of the individual test value are repeated. At this time, it is not known how many individual test values are generated (that is, how many divisions are made) until the individual test values are generated using all predetermined data in a predetermined storage area. In this way, the possibility of illegally stealing the number of divisions can be reduced by determining the amount of data used for generating the individual test value rather than determining the number of divisions. The main control unit 10 may determine the data amount used for generating the individual test value in advance, instead of determining the data amount every time one individual test value is generated. Further, the data amount used for generation of all individual test values may be made equal, and in this case, the number of divisions can be predicted when the data amount is determined.

  Moreover, in the pachinko gaming machine according to the first to third embodiments, when the function number is used as the operation inspection value, the main control unit 10 obtains the operation authentication data every time the operation inspection value is generated. It may be generated, added to the control command, and transmitted to the intermediate unit 20. In this case, the intermediate unit 20 may perform the operation authentication every time the operation authentication data is received.

  In the pachinko gaming machine according to the first to third embodiments, when a function number is used as an operation inspection value, the function number is executed for each process for executing a predetermined function of a program executed by the main control unit 10. You may assign | assign the number which increases or decreases continuously according to the order performed without duplication. By assigning the function numbers in this way, the intermediate unit 20 or the effect control unit 203 restores the operation inspection values from the received operation authentication data, and determines whether or not the values of the operation inspection values are consecutive in the order received. By doing so, operation authentication can be performed. That is, the intermediate unit 20 or the production control unit 203 stores the expected value for motion authentication in advance or performs collation processing using the motion authentication data and the expected value for motion authentication in order to perform motion authentication. There is no need to do. Accordingly, it is possible to reduce the processing load due to the operation authentication of the intermediate unit 20 or the effect control unit 203 and the data amount related to the operation authentication that occupies the storage area of the intermediate unit 20.

  Moreover, in the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10 is selected from the two types of operation inspection values of the function number and the number of authentications as the operation inspection value, but is not limited thereto. You may select from several types of operation inspection values. As other types of operation test values, the number of control command transmissions, the number of individual test values generated by the main control unit 10 (that is, the total number of divisions), or the like may be used.

  When the number of transmissions of the control command is used as the operation inspection value, the intermediate unit 20 or the effect control unit 203 that performs operation authentication authenticates the number of received control commands, that is, the number of receptions of the control command as an expected value for operation authentication. What is necessary is just to process. When the control command transmission timing comes, the main control unit 10 to be authenticated updates the value of the number of control command transmissions stored in the operation test value memory, which is a predetermined storage area of the RAM 10c, by one. Then, the updated number of transmissions is acquired as an operation inspection value. The main control unit 10 performs a predetermined calculation on the acquired operation inspection value to generate operation authentication data, adds the generated operation authentication data to the control command, and transmits the operation authentication data to the intermediate unit 20. When receiving the control command to which the operation authentication data is added, the intermediate unit 20 or the effect control unit 203 that performs the operation authentication extracts the operation authentication data and stores the expected operation authentication value (or intermediate) stored in a predetermined storage area. The operation authentication expected value) is updated by +1, and the operation authentication is performed using the extracted operation authentication data and the updated operation authentication expected value (or intermediate operation authentication expected value).

  When using the number of individual test values generated by the main control unit 10 (that is, the total number of divisions) as the motion test value, the intermediate unit 20 or the effect control unit 203 that performs motion authentication is transmitted from the main control unit 10. Authentication processing may be performed using the number of individual authentication data as the expected value for operation authentication. The main control unit 10 adds the number of the individual test values newly generated this time to the number of the individual test values stored in the RAM 10c as the operation test values at the update timing of the operation test values. The number (operation inspection value) is updated. The number of pieces of individual authentication data received this time at the value of the expected value for operation authentication stored in the RAM 20c or the RAM 30c when the intermediate unit 20 or the effect control unit 203 that performs the operation authentication comes to the update timing of the expected value for operation authentication. Is added to update the expected value for operation authentication.

  Further, the pachinko gaming machine 1 according to the first to third embodiments generates an individual test value using a predetermined half-group operation and performs an individual authentication process using a predetermined individual authentication expected value. It is not limited to. The main control unit 10 prepares a plurality of semi-group operations in advance, and performs one semi-group operation used to generate the next individual test value from the plurality of semi-group operations based on the number of divisions this time. The intermediate unit 20 or the peripheral unit 30 is configured so as to select the half group operation and the individual used in the next combining process based on the current number of connections corresponding to the switching of the half group operation in the main control unit 10. You may comprise so that an authentication expected value may be switched. Specifically, the main control unit 10 selects, for example, the next half group calculation different from the one used this time when the current division number is an odd number, and the next division number when the current division number is an even number. Select the same semigroup operation as used this time. The intermediate unit 20 or the peripheral unit 30 selects a different one from the one used this time for the half-group operation and the individual authentication expected value in the next combining process when the current number of connections is an odd number. If the number is an even number, the same half-group operation and individual authentication expected value used at the time of the next joining process are selected as those used this time. In this case, the first half group calculation is set in advance to use the same method between the main control unit 10 and the intermediate unit 20 or the peripheral unit 30. The number of divisions is a value that only the main control unit 10 can know, and the number of connections is a value that the intermediate unit 20 or the peripheral unit 30 can know only after successful individual authentication. Therefore, the fraudster cannot know the switching timing of the half group calculation in the main control unit 10 and the individual authentication expected value in the intermediate unit 20 or the peripheral unit 30. Thereby, the authentication intensity | strength with respect to the process between the main control part 10, the intermediate | middle part 20, or the peripheral part 30 can be improved.

  In the pachinko gaming machine 1 according to the first to third embodiments, the individual authentication data and the operation authentication data may be added only when a predetermined control command is transmitted, for example, a predetermined control command. In this case, the main control unit 10 determines whether or not the control command is a predetermined control command, and generates individual authentication data and operation authentication data in the case of the predetermined control command. The main control unit 10 transmits to the intermediate unit 20 or the peripheral unit 30 a control signal with authentication data in which the generated individual authentication data and operation authentication data are added to the control command. Note that the main control unit 10 newly starts the individual authentication data and the operation even when the predetermined timing (for example, the transmission timing of the predetermined control command) is reached until all of the generated individual authentication data and operation authentication data are transmitted. A control signal with authentication data is transmitted without generating authentication data. As described above, by generating the individual authentication data and the operation authentication data only at the predetermined timing, it is possible to limit the number of generations of the authentication data, and to reduce the processing load due to the authentication processing.

  Here, the predetermined control command refers to various control commands for instructing the operation of the pachinko gaming machine 1 (for example, initialization operation, performance operation, customer waiting demonstration, etc.) while the pachinko gaming machine 1 is energized. A specific control command arbitrarily selected from the above. More specifically, the predetermined control command is, for example, a jackpot command transmitted while the jackpot state continues, a jackpot start command for starting the jackpot state processing, and a jackpot state process for ending the jackpot state processing. A jackpot end command, a jackpot reach command for causing the peripheral unit 30 to execute a process of reaching the jackpot, a power-on command for causing the peripheral unit 30 to execute a power-on process, and the peripheral unit 30 in a non-game state A customer waiting demo command for executing a demo display, a customer waiting demo stop command for stopping the demonstration display in the non-gaming state in the peripheral portion 30, and executing processing when the lottery result at the lottery is off in the peripheral portion 30 A command to make it off, called an open lottery of ordinary electric accessories (electric tulips) or so-called fake It refers to such that jackpot and the small hit command transmitted for the duration of the small contact state so as to open only for a short time a special electric combination thereof as well. As the predetermined control command, there are, for example, a power-off command, an unreach reach command, an unreach non-reach command, a round start command, and a round end command.

  In the pachinko gaming machine 1 configured as described above, at the timing of transmitting a predetermined control command, authentication processing is performed using authentication data for authenticating the validity of the main control unit 10. The processing load on the main control unit 10 and the peripheral unit 30 is increased only during the period when the control command data 301 of a predetermined control command is received. The rate at which the processing load increases can be suppressed.

  Further, since the authentication data is added only to the control command data of the predetermined control command, it is only necessary to add an authentication process related to the predetermined control command to the program executed by the peripheral unit 30. Accordingly, since it is not necessary to design a new timing for the entire program executed by the peripheral unit 30, the timing for adding the authentication function is compared with the case where the authentication data is added to the control command data of all control commands. Design, implementation of functions, verification of functions, etc. can be realized more easily and with less man-hours.

  Further, only when the main control unit 10 transmits a predetermined control command to the intermediate unit 20, when at least one of the individual authentication data and the operation authentication data is added to the control command data, the authentication process is performed in a predetermined manner. Since this is only at the time of transmission of the control command data of the control command, it is possible to suppress the rate at which the processing load on the main control unit 10 and the peripheral unit 30 increases due to the authentication process. When the predetermined control command is a jackpot command, the jackpot command is transmitted for each round of jackpot, so the authentication process is performed multiple times during a certain period in the jackpot state, improving the accuracy of the authentication process. be able to.

  Also, when the predetermined control command is a jackpot start command or jackpot end command, the jackpot start command or jackpot end command is a control command for starting or ending the jackpot state, and compared with other control commands, the transmission frequency Is low. Therefore, the possibility that the authentication data is extracted from the control signal can be reduced. Further, even if authentication data is extracted from the control signal, the number of samples that can be acquired is small, so that the risk that the authentication data is analyzed can be reduced.

  When the predetermined control command is a jackpot reach command, the jackpot reach is generated more frequently than the jackpot reach. Moreover, the occurrence timing of jackpot reach has randomness. Therefore, by performing the authentication process when transmitting the jackpot reach command data, the execution positions of the authentication process on the time axis are distributed. And the reliability of an authentication process can be improved by distributing the implementation position of the authentication process on a time axis in this way. This is because even if authentication data communication failure or authentication data tampering is performed for a certain period, authentication processing is performed at random time, so the possibility of avoiding communication failure and tampering may be avoided This is because of the increase.

  Further, when the predetermined control command is a power-on command, the power-on command is transmitted when the pachinko gaming machine 1 is initialized, such as when the pachinko gaming machine 1 is powered on or reset. The initialization process 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 as in the present invention, the rate of increase in the number of steps (man-hours) required for program design and testing is reduced compared to the case where the authentication process is incorporated during the game-related process. can do. That is, by incorporating the authentication process during the initialization process, it is possible to obtain development merit and quality control merit. Further, if authentication processing is incorporated during initialization processing, authentication processing is performed immediately after the pachinko gaming machine 1 is started, so that even if a fraud is performed after the game store is closed, the customer enters the store. Fraud can be detected before. Therefore, the risk of damage caused by fraud can be reduced.

  When the predetermined control command is a customer waiting demo command or a customer waiting demo stop command, the customer waiting demo command or the customer waiting demo stop command indicates that the pachinko gaming machine 1 is in a non-game state, that is, the main of the pachinko gaming machine 1 This is transmitted when the game (game progress) related process is not performed, so that an increase in processing load due to the authentication process does not affect the game related process. For this reason, even if the main control unit 10 or the peripheral unit 30 (the effect control unit 203) does not have a high processing capacity, or the pachinko gaming machine 1 has a large processing load on the game-related processing, the authentication processing function Can be added. Further, since the customer waiting demo command and the customer waiting demo stop command are commands issued before the customer operates the pachinko gaming machine 1, the customer detects an illegal act before operating the pachinko gaming machine 1. Can do.

  Furthermore, when the predetermined control command is a loss command, “out of” occurs most frequently as a lottery result at the time of lottery, so that authentication data 303 is added to the control command when the loss command data is transmitted. The flow from the lottery to the authentication process can be regarded as a basic form of processing of the pachinko gaming machine 1. On the other hand, processing at the time of jackpot reach and jackpot is classified into special processing such as changing the presentation method for each model of pachinko gaming machine 1, but processing at the time of losing is different for each model of pachinko gaming machine 1 There are few differences. For this reason, if the authentication process is incorporated in the process at the time of disconnection as in the first embodiment, the main body of the pachinko gaming machine 1 can be reused for another model without making a major change in the flow of the authentication process. Is possible.

  The intermediate unit 20 may add the intermediate authentication information to the control command only when transmitting a predetermined control command to the peripheral unit 30. In this case, since the authentication process of the intermediate unit 20 is performed only when a predetermined control command is transmitted, the rate at which the processing load of the peripheral unit 30 increases due to the authentication process can be suppressed. In this case, it is only necessary to add an authentication process related to a predetermined control command to the program executed by the intermediate unit 20. Accordingly, since it is not necessary to design a new timing for the entire program executed by the intermediate unit 20, the design and function of the timing for adding the authentication function as compared with the case where the intermediate authentication information is added to all the control commands. Implementation, functional verification, etc. can be realized more easily and with less work man-hours.

  In addition, in the pachinko gaming machine 1 according to the first to third embodiments, the main control unit 10 includes individual control command data and accompanying data in addition to a control signal with authentication data to which individual authentication data and operation authentication data are added. A control signal with individual authentication data to which only authentication data is added, or a control signal with operation authentication data to which only operation authentication data is added to control command data and accompanying data may be transmitted to the intermediate unit 20 or the peripheral unit 30, respectively. Good. Further, the intermediate unit 20 may add various authentication results and various authentication data constituting the intermediate authentication information to different control signals and transmit them separately to the peripheral unit 30.

In addition, the pachinko gaming machine 1 according to the first to third embodiments has been described as adding the individual authentication data and the operation authentication data to the control command when transmitting the control command. However, the gaming machine according to the present invention is not limited thereto. It is not limited. The main control unit 10 may add authentication data to a data signal different from the control command and transmit it to the intermediate unit 20 or the peripheral unit 30. For example, a timing for transmitting / receiving authentication data between the main control unit 10 and the intermediate unit 20 or the peripheral unit 30 is set in advance, for example, authentication data is added to an arbitrary data signal and transmitted every predetermined time. Just keep it. Further, the main control unit 10 may output the data signal to which the authentication data is added so as to have a data structure different from the control command so that it can be understood.
Further, the main control unit 10 may transmit the authentication data itself as a data signal without adding the authentication data to the data signal.

In each of the above embodiments, the present invention is applied to a pachinko gaming machine. However, the present invention is not limited to this, and the present invention is not limited to a pachinko gaming machine such as a sparrow ball gaming machine or an arrangement ball. The present invention can also be applied to other gaming machines such as a revolving type gaming machine such as a gaming machine or a slot machine. Even in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring similarly to the above-described embodiments.
In addition, each of the above embodiments can utilize each other's technology as long as there is no particular contradiction or problem in the purpose, configuration, or the like.
