(3) An illegal board (impersonated board) is provided between the main control board and the peripheral board, and the ROM of (2) above is replaced.

  In order to prevent such illegal acts, there are the following conventional gaming machines. That is, this gaming machine is connected to the main control unit (main control unit) that determines whether or not the privilege can be granted and stores the third identification information, and stores the first identification information. A first sub-control unit (first peripheral unit), and a second sub-control unit (second peripheral unit) connected to the main control unit and storing second identification information. In this gaming machine, information can be output only from the main control unit toward the first peripheral part, and the main control part and the second peripheral part can mutually input and output information. The second peripheral part has means for outputting the second identification information to the main control part. On the other hand, the main control unit has means for outputting the second identification information and the third identification information to the first peripheral portion. The first peripheral portion includes a computing unit that performs a predetermined computation using the first identification information, the second identification information, and the third identification information, and whether or not the gaming machine has been illegally modified based on a computation result of the computing unit. Means for determining whether or not (see, for example, Patent Document 1). Hereinafter, this technique is referred to as a first conventional example.

  In addition, the conventional gaming machine includes a symbol display device that displays a jackpot symbol, a main control device (main control unit) that transmits data to the symbol control unit according to the game situation, and a main control unit that responds to the game situation. Some include a symbol control unit (peripheral unit) that controls the symbol display device based on received control data. In this pachinko gaming machine, the main control unit performs encryption corresponding to the first key data on the first storage means for storing the first key data and the control data for controlling the operation of the symbol control unit. An encryption unit; a transmission unit that transmits data obtained by encrypting control data corresponding to a game situation to the peripheral unit; and a first key change unit that changes the first key data at a predetermined timing. ing.

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

  In addition, some conventional pachinko gaming machines include a main control board (main control unit) and a peripheral board (peripheral part) that performs predetermined processing based on a control command transmitted by the main control unit. In this pachinko gaming machine, when the control command to be transmitted to the peripheral unit is a predetermined control command, the main control unit adds authentication data for authenticating the main control unit to the predetermined control command and transmits it to the peripheral unit. To do. When the peripheral unit receives a predetermined control command, the peripheral unit authenticates the main control unit based on the authentication data transmitted in addition to the predetermined control command (see, for example, Patent Document 3). 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.

  The present invention has been made in view of the above circumstances, and can detect fraudulent acts and malfunctions of gaming machines due to replacement of a regular main control board and an unauthorized main control board of a gaming machine.

<Embodiment 1>
Hereinafter, Embodiment 1 which is a form for implementing this invention with reference to drawings is demonstrated.
FIG. 1 is a block diagram showing a configuration of a gaming machine 1 according to Embodiment 1 of the present invention. The gaming machine 1 includes a main control unit 10, a rear stage unit 20, and a peripheral unit 30. The main control unit 10 includes data storage means 11, determination means 12, individual test value generation means 13, and operation authentication data generation means 14. Data such as a program used in the main control unit 10 is stored in the data storage unit 11. The determination unit 12 determines the number of divisions that is the number of predetermined data among the data stored in the data storage unit 11. Here, the predetermined data is all or a part of the data stored in the data storage unit 11.

  The individual test value generation means 13 generates an individual test value used for authenticating the validity of the main control unit 10. Specifically, the individual test value generation unit 13 divides predetermined data stored in the data storage unit 11 by the number of divisions determined by the determination unit 12, and satisfies the combination rule for each divided data. Binary operation (for example, addition, multiplication, exclusive OR) is performed to generate individual test values for the number of divisions (the same number as the number of divisions).

  The operation authentication data generation unit 14 authenticates the operation order of the main control unit 10 and generates operation authentication data for authenticating that the process (operation) by the main control unit 10 is continuously executed. Specifically, the operation authentication data is, for example, a number (hereinafter referred to as a function number) assigned in advance without duplication for each process for executing a predetermined function in a program executed by the main control unit 10, In the process 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), it is generated using a value that varies according to a predetermined law (hereinafter referred to as an operation inspection value). The operation authentication data includes data obtained by performing a predetermined operation on the operation inspection value and the operation inspection value itself. Further, the operation authentication data generation unit 14 switches the type of operation inspection value used for generation of the next operation authentication data based on the number of divisions.

  Then, the main control unit 10 adds the individual authentication data for the number of divisions obtained by performing the encryption process to the individual test values for the generated number of divisions and the operation authentication data to the control command. The data is transmitted to the subsequent stage unit 20 via the peripheral unit 30.

On the other hand, the post-stage unit 20 includes a calculation value storage unit 21, an individual authentication unit 22, an operation authentication expected value storage unit 23, and an operation authentication unit 24. The calculated value storage means 21 is a calculated value obtained by performing a binary operation satisfying the coupling rule using predetermined data stored in the data storage means 11 constituting the main control unit 10 (hereinafter referred to as individual authentication). The expected value is stored in advance. The individual authentication means 22 performs a binary operation satisfying the above-mentioned combination rule on the individual inspection value added to the control command and transmits the result of the calculation and the individual authentication value stored in the operation value storage means 21. Whether or not the main control board on which the main control unit 10 is mounted is an authorized main control board by authenticating the individual main control board on which the main control unit 10 is mounted based on whether or not the expected value matches. That is, an individual authentication process for authenticating the normality of the main control board (main control unit) is performed.
The operation authentication expected value storage unit 23 stores a plurality of operation authentication expected values for authenticating the operation authentication data generated by the operation authentication data generation unit 14. The operation authentication unit 24 performs an operation authentication process for authenticating the continuity of the operation sequence of the main control unit 10 based on whether or not the operation authentication data matches the expected value for operation authentication. In addition, the action authentication unit 24 switches the expected value for action authentication used for the next action authentication process based on the number of individual test values subjected to the current individual authentication process.
Then, the post-stage unit 20 adds the authentication result obtained by the individual authentication unit 22 and the operation authentication unit 24 to the control command and transmits it to the peripheral unit 30. Thereby, the peripheral part 30 performs the process according to the authentication result added to the control command.

  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 follows [1] to [6], 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 acquires 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 to obtain individual test values for the number of divisions for authenticating the main control unit 10. Generate. It should be noted that the method for generating the individual test value (for example, the type of binary operation that satisfies the combining law used for generating the individual test value) is determined at the time of the previous transmission of the control signal with authentication data.

“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 determines whether or not the main control board on which the main control unit 10 is mounted is a regular main control board, that is, the normality of the main control board (main control unit). The individual authentication data for authenticating the operation and the operation authentication data for authenticating the operation sequence of the main control unit 10 are generated, the generated authentication data is added to the control command, and the post-stage unit 20 via the effect control unit 203. Send to. Here, the data for authenticating the main control unit 10 added to the control command, that is, the individual authentication data and the operation authentication data are collectively referred to simply as “authentication data”. The individual authentication data is data obtained by performing encryption processing on each individual test value or these individual test values. In the first embodiment, the individual authentication data is described as data obtained by encrypting the individual test value. However, the present invention is not limited to this, and the individual test value itself is authenticated as the individual authentication data. You may perform the process regarding. In this case, it is not necessary to perform an encryption process on the individual test value in the main control unit, and it is not necessary to perform a decryption process on the individual authentication data when extracting the individual test value in the subsequent stage. The increase in processing load can be suppressed.

  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 303 obtained by performing encryption processing on each individual test value is transmitted to the subsequent stage unit 20 via the effect control unit 203, any processing is performed. The possibility that each individual test value is analyzed by a fraudulent person can be reduced as compared with a case where each individual test value is transmitted as it is to the subsequent stage unit 20 via the effect control unit 203.

  The main control unit 10 may perform different encryption processing on each individual test value. Specifically, for example, a processing method for performing a processing process such as an error detection calculation for generating individual authentication data from each individual test value is changed. This also applies to intermediate processing in the later stage unit 20 described later.

  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.

  Further, the main control unit 10 prepares a plurality of methods such as encryption processing in advance, and a plurality of encryption processing based on the current number of divisions (number of data blocks) determined in the processing [1]. One encryption process used for the next generation of individual authentication data may be selected from the list. 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.

(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.

  Note that 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 each timing is included in the control program of the main control unit. What is necessary is just to incorporate the program which performs the process which produces | generates an individual test value, and the process which produces | generates individual authentication data using each individual test value.

[4] Generation of Operation Authentication Data Next, a method for generating operation authentication data will be described. The operation authentication data is data obtained by performing a predetermined calculation on the operation inspection value. The operation inspection value is generated using a value that fluctuates according to a predetermined rule in the process performed by the main control unit 10 such as a function number and the number of times of authentication. The main control unit 10 stores the generated operation inspection value in the operation inspection value storage area of the RAM 10c. When it is time to generate the operation authentication data, the main control unit 10 acquires the operation inspection value stored in the operation inspection value storage area of the RAM 10c, performs a predetermined operation on the acquired operation inspection value, and obtains the operation authentication data. Generate. Here, the predetermined calculation is, for example, a calculation using a hash function, a parity check, a cyclic redundancy check, a checksum, or the like. In the first embodiment, the operation authentication data is data obtained by performing a predetermined calculation on the operation inspection value. However, the present invention is not limited to this, and the operation authentication process uses the operation inspection value itself as operation authentication data. May be performed.

  Note that the main control unit 10 may perform an encryption process similar to the individual test value on the operation authentication data. Further, the operation authentication data may be generated by performing an encryption process on the data including the operation command value and the control command data transmitted along with the operation authentication data. Further, the operation authentication data may include data related to control command data and accompanying data transmitted together with the operation authentication data. By generating operation authentication data using control command data and accompanying data transmitted with the operation authentication data, even if the operation authentication data is reused by an unauthorized control unit, the operation authentication data and the control command Can not be matched, 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.

  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 storage area, which is a predetermined 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 18 are assigned to each of the 15 round jackpot commands. In this way, continuity of the operation sequence of the main control unit 10 is increased by assigning consecutive function numbers to control commands that are generated continuously in time series and checking the continuity of the function numbers that are generated continuously. It 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.

  When it is time to generate the operation authentication data, the main control unit 10 acquires a plurality of operation inspection values stored in the operation inspection value storage area of the RAM 10c, performs a predetermined calculation on each of the operation inspection values, and obtains a plurality of operation authentication data. Generate. When the main control unit 10 generates a plurality of operation test values using the identification number, the main control unit 10 retains information on the order in which the plurality of operation test values are generated, that is, the operation order of the main control unit 10. A plurality of operation authentication data corresponding to each of the inspection values is generated. For example, the main control unit 10 generates a plurality of operation authentication data by performing a predetermined calculation on each of the operation inspection values while holding an array of a plurality of function numbers (operation inspection values) arranged in the acquired order. To do. Therefore, the plurality of arranged operation authentication data indicates the operation order when the main control unit 10 executes various programs, like the plurality of operation inspection values.

  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 authentication processes since the power of the pachinko gaming machine 1 is turned on, and the authentication process is a general term for processes that combine the individual authentication process and the operation authentication process. That is, the number of authentications is the number of times that the main control unit 10 has performed the individual authentication value generation process. The main control unit 10 stores the number of authentications as an operation inspection value in an operation inspection value storage area that is a predetermined 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. When it is time to generate the operation authentication data, the main control unit 10 acquires the operation inspection value (number of authentications) stored in the operation inspection value storage area of the RAM 10c, and performs a predetermined calculation to generate operation authentication data. .

  Further, the main control unit 10 switches the operation authentication data generation method, for example, the type of the operation inspection value used when generating the operation authentication data, based on the division number. Specifically, the main control unit 10 switches the type of operation inspection value when the number of divisions is an odd number, and continuously uses the type of operation inspection value without switching when the number of divisions is an even number. The switching of the type of operation inspection value will be described in detail later.

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

[5] Adding data to the control signal The main control unit 10 generates the control signal with authentication data by adding individual authentication data and operation authentication data to the control command data and accompanying data transmitted to the effect control unit 203. .

[6] Transmission of Control Signal The main control unit 10 transmits a control signal with authentication data to the rear stage unit 20 via the effect control unit 203.

  Here, an example of a data format of a control signal transmitted from the main control unit 10 to the rear stage unit 20 via the effect control unit 203 will be described with reference to a schematic diagram shown in FIG. In addition, when generating the operation authentication data using the function number as the operation inspection value, a plurality of operation authentication data are generated, but only one operation authentication data is shown in FIG. 5 for simplicity. FIG. 5 (1) shows a normal control signal 300 including control command data 301 and accompanying data 302. In this case, 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, the main control unit 10 includes individual authentication data 303 and operation authentication data 304 in addition to the control command data 301 and accompanying data 302 as shown in FIG. A control signal with authentication data 310 is generated and output. Although not shown in FIG. 5, the normal control signal 300 and the control signal with authentication data 310 include BCC (Block Check Character) and the like, as with the 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 control signals with authentication data 311 and 312 described later.

  Further, when transmitting only the individual authentication data 303, the main control unit 10 adds individual authentication data including the individual authentication data 303 in addition to the control command data 301 and the accompanying data 302 as shown in FIG. 5 (3). A control signal 311 is generated and output. When transmitting only the operation authentication data, the main control unit 10 controls the operation authentication data with the operation authentication data 304 in addition to the control command data 301 and the accompanying data 302 as shown in FIG. A signal 312 is generated and output.

  The control signal with authentication data is limited to the control signal with authentication data 310 arranged in the order of the control command data 301, the accompanying data 302, the individual authentication data 303, and the operation authentication data 304 as shown in FIG. For example, the individual authentication data 303 and the operation authentication data 304 may be provided at the head of the control signal, or the individual authentication data 303 and the operation authentication data 304 may be inserted between the control command data 301 and the accompanying data 302. The control command data 301, the accompanying data 302, the individual authentication data 303, and the operation authentication data 304 may be arranged in any order. Similarly, the individual authentication data-added control signal 311 and the operation authentication data-added control signal 312 may be arranged in any order.

  In this way, by including the authentication data (individual authentication data 303 and operation authentication data 304) in the control signal, compared with the case of transmitting the authentication data alone, between the main control unit 10 and the effect control unit 203. An increase in communication load can be suppressed. Further, by including the authentication data in the control signal, it is possible to reduce the risk that the authentication data is extracted from the communication data and analyzed as compared with the case where the authentication data is transmitted alone.

(Rear part)
The rear stage unit 20 includes a CPU 20a, a ROM 20b, a RAM 20c, and the like. The CPU 20a executes processing (hereinafter referred to as intermediate processing) based on a program (program code) stored in advance in the ROM 20b. The ROM 20b performs a plurality of half-group operations using a program code for the CPU 20a to execute intermediate processing and a predetermined program code to be divided that is stored in advance in the ROM 10b constituting the main control unit 10. A plurality of expected values for individual authentication obtained in advance are stored in advance. Among the storage areas of the ROM 20b, the storage area in which the plurality of expected values for individual authentication are stored in advance can correspond to, for example, the calculated value storage means 21 shown in FIG. The RAM 20c stores an expected value for operation authentication for authenticating the operation sequence of the main control unit 10. Among the storage areas of the RAM 20c, the storage area in which the expected value for operation authentication is stored can correspond to, for example, the expected value storage means for operation authentication 23 shown in FIG. The RAM 20c functions as a work area for calculations performed when the CPU 20a executes intermediate processing.

  The post-stage unit 20 stores an expected value for operation authentication corresponding to each type of operation authentication data generation method. The expected value for operation authentication for authenticating the operation authentication data generated using the function number is data formed by associating a plurality of operation authentication data so that the operation order of the main control unit 10 can be determined. For example, it is a data table in which a plurality of operation authentication data are arranged in an order indicating the operation order of the main control unit 10. The expected value for operation authentication for authenticating operation authentication data generated using the number of authentications is a value indicating the number of authentications. In this case, as in the case of the main control unit 10, the post-stage unit 20 adds 1 to the value of the expected value for operation authentication (number of times of authentication) stored in the RAM 20 c every time the authentication process is performed, and creates a new operation authentication. Expected value (number of times of authentication) is generated, and this operation inspection value is stored in the RAM 20c.

In the first embodiment, the intermediate processing is as follows [1] to [6].
[1] Reception of Control Signal The rear stage unit 20 receives a control signal with authentication data including the control command data 301, accompanying data 302, individual authentication data 303, and operation authentication data 304 from the main control unit 10 through the effect control unit 203. Alternatively, a control signal with individual authentication data composed of control command data 301, accompanying data 302 and individual authentication data 303, or a control signal with operation authentication data comprising control command data 301, accompanying data 302 and operation authentication data 304 is received.

[2] Individual test value extraction The post-stage unit 20 extracts the individual authentication data 302 from the control signal with authentication data. Next, the post-stage unit 20 applies a decryption process corresponding to the encryption process used when generating the individual authentication data to the extracted individual authentication data, and extracts an individual test value. The rear stage unit 20 stores the extracted individual test value in a predetermined storage area of the RAM 20c (hereinafter referred to as an individual test value memory).

[3] Individual authentication The post-stage unit 20 performs a semi-group operation on all the individual test values stored in the individual test value memory in the order shown below, so that the main control unit 10 is authorized. An individual authentication process for authenticating the normality of the main control unit 10 is performed by authenticating the individual of the main control unit 10 as to whether or not it is a main control unit.
The {1} rear stage unit 20 performs a semi-group operation (hereinafter referred to as a combining process) using all the individual test values stored in the individual test value memory.
{2} The subsequent stage unit 20 reads the expected value for individual authentication stored in advance from a predetermined storage area of the ROM 20b.

The {3} latter stage unit 20 determines whether or not the calculation result in the process of {1} (hereinafter referred to as a combination result) matches the expected value for individual authentication read out in the process of {2} (hereinafter referred to as “below”). , Referred to as matching process).
The post-stage unit 20 determines that the individual authentication is successful when the combined result matches the expected value for individual authentication.
Since the semi-group operation satisfies the above-mentioned combination rule, the expectation for individual authentication that is the 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 The value matches the combined result obtained by performing the semigroup operation on the individual test values for the number of divisions generated from the predetermined program code. As a result, the post-stage unit 20 authenticates the validity of the main control unit 10.
On the other hand, the post-stage unit 20 determines that the individual authentication has not succeeded when the combined result and the expected value for individual authentication do not match.

    If the individual authentication is successful in the processing of {4} {3}, the rear stage unit 20 generates an authentication result indicating that the individual authentication is successful, and all the individual examinations stored in the predetermined storage area of the RAM 20c Erase the value.

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

(Calculation example of expected value generation for individual authentication)
A method for generating the expected value for individual authentication will be described with reference to FIG.
The subsequent stage unit 20 holds a value obtained by performing the semigroup operation on the entire predetermined program code to be divided stored in the program code storage area 400 as an expected value for individual authentication. For example, the expected value for individual authentication in the case of method A is “0x4E” which is the sum of “0x01” to “0x0C”. Further, the expected value for individual authentication in the case of method B is “0x0C” which is an exclusive OR of “0x01” to “0x0C”. The rear stage unit 20 holds the same number of expected values for individual authentication as the number of half-group operations that are individual test value generation methods by the main control unit 10.

  The means for executing the individual authentication process can correspond to, for example, the individual authentication means 22 shown in FIG.

[4] Operation Authentication Data Extraction The post-stage unit 20 extracts the operation authentication data 304 from the control signal with authentication data. Next, when the main control unit 10 performs an encryption process on the operation authentication data, the subsequent stage unit 20 performs a decryption process corresponding to the encryption process on the operation authentication data. The rear stage unit 20 stores the extracted operation authentication data in a predetermined storage area of the RAM 20c (hereinafter referred to as an operation authentication data memory). When the main control unit 10 changes the encryption process according to the number of divisions, the subsequent unit 20 also changes the decoding process according to the number of divisions to combine the operation authentication data.

[5] Operation Authentication The rear stage unit 20 performs an operation authentication process for authenticating the operation sequence of the main control unit 10 and performs authentication as to whether or not the main control unit 10 is a regular main control unit.
{1} The post-stage unit 20 reads the operation authentication data stored in the operation authentication data memory.
{2} The expected value for operation authentication corresponding to the operation authentication data to be authenticated is read out from the expected value for operation authentication stored in the predetermined storage area of the RAM 20c of the rear stage unit 20.

{3} The latter stage unit 20 determines whether or not the operation authentication data read in the process {1} matches the expected value for operation authentication read in the process {2} (collation process).
When the {3-1} operation inspection value is generated using the function number, the plurality of operation authentication data read in the process {1} and the expected value for operation authentication read in the process {2} Using the data table, a verification process is performed to determine whether a plurality of operation authentication data are arranged in a regular order. As a result of the collation processing, when a plurality of operation authentication data are arranged in a normal order, the rear stage unit 20 determines that the operation authentication is successful. On the other hand, when the plurality of operation authentication data are not arranged in the regular order, the rear-stage unit 20 determines that the operation authentication has not succeeded.
When the {3-2} operation inspection value is generated using the number of authentications, the main control unit determines the operation authentication data read in the process {1} and the number of authentications read in the process {2}. A verification process is performed to determine whether or not the expected value for operation authentication, which is a value obtained by performing the same encryption process as the encryption process performed on the number of times of authentication 10, matches. As a result of the collation processing, when the operation authentication data matches the expected value for operation authentication, the subsequent stage unit 20 determines that the operation authentication is successful. On the other hand, if the operation authentication data and the expected value for operation authentication do not match, the subsequent stage unit 20 determines that the operation authentication has not succeeded.

    When the operation authentication is successful in the processing of {4} {3}, the rear stage unit 20 generates an authentication result indicating that the operation authentication is successful, and all the operation inspection values stored in the predetermined storage area of the RAM 20c Erase.

    If the operation authentication is not successful in the processing of {5} {3}, the rear stage unit 20 generates an authentication result indicating that the operation authentication is not successful.

    {6} The rear stage unit 20 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 20c, that is, the new value of the number of authentications, 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 20c.

  The rear stage unit 20 switches the expected value for operation authentication based on the number of combinations corresponding to the switching of the type of operation inspection value in the main control unit 10. For example, the post-stage unit 20 switches the expected value for operation authentication in response to switching of the type of operation inspection value of the main control unit 10 when the number of connections is an odd number, and the operation used last time when the number of connections is an even number. Continue to use the expected value for authentication. The number of divisions is a value that only the main control unit 10 knows, and the subsequent unit 20 can know the value as the number of connections 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 expected value for operation authentication (switching of the authentication method). Thereby, it is possible to prevent an illegal operation person from generating an operation inspection value illegally. In addition, the strength of the authentication process between the main control unit and the subsequent stage unit can thereby be improved.

  The means for executing the action authentication process can correspond to, for example, the action authentication means 24 shown in FIG.

  Note that the expected value for individual authentication used by the subsequent stage unit 20 for verification may be stored in advance in a predetermined storage area of the ROM 20b constituting the subsequent stage unit 20 at the time of manufacture, for example, but is not limited thereto. It is good also as transmitting to the back | latter stage part 20 from a structure part. Examples of other components include a prize ball control unit 204 and a dedicated processing unit (hereinafter referred to as an expected value calculation unit) for generating an expected value for individual authentication. Further, the expected value calculation unit may transmit the expected value stored in advance to the subsequent stage unit 20. In addition, a coefficient necessary for calculating an expected value may be transmitted from an external device to the subsequent stage unit 20 or the expected value calculation unit via an external connection interface (not shown). As described above, if the expected value is not stored in advance in the predetermined storage area of the ROM 20b constituting the rear stage unit 20, the individual test value can be changed afterwards. It becomes possible.

[6] Generation of Authentication Unsuccessful Signal The post-stage unit 20 is at least one of the result of individual authentication obtained by the individual authentication process of [3] or the result of operation authentication obtained by the action authentication process of [5]. If one of the results indicates an unsuccessful authentication, an unsuccessful authentication signal is generated based on the unsuccessful authentication result. At this time, the post-stage unit 20 may perform an encryption process on the authentication unsuccessful signal in the same manner as when the main control unit 10 generates the individual authentication data.

[7] Transmission of Authentication Unsuccessful Signal The subsequent stage unit 20 transmits an authentication unsuccessful signal to the effect control unit 203. Details of these intermediate processes (the processes [1] to [7]) will be described later. For example, the means for executing the authentication process can correspond to the authentication means 22 shown in FIG.

(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 effect during the game, and executes the effect lottery and effect processing based on the control command transmitted from the main control unit 10 based on the program (program code) stored in advance in the ROM 203b. . The ROM 203b stores in advance a program code for the CPU 203a to execute a lottery and a production process of production and past production patterns. The RAM 203c functions as a work area for data and the like in arithmetic processing performed when the CPU 203a executes lottery and effect processing of effects. 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, the effect control unit 203 performs a lottery based on the control command and finalizes effects such as an effect background pattern, a reach effect pattern, and an appearance character. At the same time, 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.

Normally, 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. 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. .

  In addition to the processing outlined above, the effect control unit 203 is based on a program stored in advance in the ROM 203b in accordance with the type of control signal transmitted from the main control unit 10 or the subsequent stage unit 20 as follows. Processing related to authentication shown in [1] to [3] is executed.

[3] Processing Based on Authentication Unsuccessful Signal When the production control unit 203 receives an authentication unsuccessful signal from the subsequent unit 20, the effect control unit 203 notifies that the authentication is unsuccessful.
The details of the processing related to authentication in the effect control unit 203 will be described later.

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 rear stage unit 20, the stage control unit 203, the prize ball control unit 204, and the lamp control unit 205 having the above-described configuration are respectively different printed boards (main control board, intermediate board, stage control board, (Prize ball control board, 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 rear stage 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 authentication data shown in FIG. And the presence or absence of accompanying data are not considered.

Processing including control command transmission by the main control unit 10 to the effect control unit 203 and the prize ball control unit 204 will be described with reference to the 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. For example, the main control unit 10 sets a predetermined value in the stack pointer as an initial setting process, and waits for the rear stage unit 20, the production 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 effect control unit 203 and the prize ball control unit 204, and then proceeds to step S3. When receiving the power-on command, the effect control unit 203 transmits the power-on command to the rear stage unit 20 and the lamp control unit 205. 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 performs an effect control unit 203, a prize ball control unit 204, and Control commands transmitted to the rear stage unit 20 and the lamp control unit 205 via the effect control unit 203, and initial control information for controlling the game at the start-up after the power is turned on, for example, control mode, backup data, etc. 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 effect control unit 203, and then proceeds to step S7. 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 includes, for example, control data (accompanying data) such as a jackpot type code (whether it is a normal hit or per probability fluctuation), reach, symbol variation time, etc. in the effect control unit 203. After transmitting the jackpot reach command (design variation command), the process proceeds to step S14. In step S14, the main control unit 10 determines whether or not the symbol variation time has elapsed. If the determination result in step S14 is “NO”, that is, if the symbol variation time has not elapsed, the main control unit 10 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S14 is “YES”, and the main control unit 10 proceeds to step S15.

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

  On the other hand, if the determination result in step S12 is “NO”, that is, if the jackpot determination random number obtained in the process of step S10 is not a predetermined jackpot random number, the main control unit 10 proceeds to step S19. In step S19, the main control unit 10 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 effect control unit 203, and then the process proceeds to step S20.

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

  In step S22, the main control unit 10 determines whether or not the power of the pachinko gaming machine 1 has been turned off. 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 an end process command to the effect control unit 203 and then ends a series of processes.

  Here, FIG. 8 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. 8 (1) is transmitted at random. The jackpot start command shown in FIG. 8 (2) is transmitted only once when shifting to the jackpot state when a jackpot has actually occurred. Further, the jackpot command shown in FIG. 8 (3) is continuously transmitted for each round after shifting to the jackpot state. Also, the jackpot end command shown in FIG. 8 (4) is transmitted only once when all rounds of the jackpot state are completed and the state transitions to the normal state.

  Next, processing by the effect control unit 203 will be described. In the following, processing of the effect control unit 203 at the time of symbol variation (when a jackpot reach command (see step S13 shown in FIG. 7) or a loss reach command (see step S19 shown in FIG. 7) is received) and a jackpot reach command is received. explain.

First, the symbol variation process by the effect control unit 203 will be described with reference to the flowchart shown in FIG.
Whether or not the effect control unit 203 has received either a jackpot reach command (see step S13 shown in FIG. 7) or a miss reach command (see step S19 shown in FIG. 7), which is a symbol variation command, from the main control unit 10. Is determined (see step S31 in FIG. 9). 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. 7) has been received from the main control unit 10. 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. 7) is received from the main control unit 10 (see step S41 in FIG. 10). 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. 7) has been received from the main control unit 10. 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 | generation 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 or not a jackpot end command (see step S18 shown in FIG. 7) has been received from the main control unit 10. 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. 9) has been received from the effect control unit 203 (see step S51 in FIG. 11). 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. 9) 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.

By the way, as described above, gaming media are paid out regardless of the game due to fraudulent acts performed on the gaming machine or malfunction of the gaming machine due to noise or the like, and the gaming store suffers a great deal of damage. There is. Therefore, in order to prevent malfunctions of the gaming machine due to the above-mentioned fraudulent acts and noise, the pachinko gaming machine 1 according to the present embodiment 1 is provided with the rear stage unit 20 at the rear stage of the effect control unit 203.
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 using the operation inspection value. The authentication data is added to the control command and transmitted to the rear stage unit 20 via the effect control unit 203.

  The post-stage unit 20 authenticates the individual of the main control unit 10 using each individual test value obtained from the individual authentication data received from the main control unit 10 via the effect control unit 203, and uses the operation authentication data. Thus, by authenticating the operation order as to whether the main control unit 10 is a regular main control unit, authentication is performed as to whether the main control unit 10 is a regular main control unit. Next, the post-stage unit 20 sends an authentication unsuccess signal to the effect control unit 203 when at least one of the authentication result obtained by the individual authentication process or the authentication result obtained by the operation authentication process is unsuccessful. Send. Then, the effect control unit 203 notifies the fact based on the authentication failure signal received from the subsequent stage unit 20. In this way, authentication processing is performed with the latter-stage unit 20 as the authenticator and the main control unit 10 as the person to be authenticated, and the validity of the control command transmitted from the main control unit 10 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 also be reduced.

  Hereinafter, processing related to authentication performed between the main control unit 10, the rear stage unit 20, and the peripheral unit will be described. Hereinafter, processing related to authentication between the main control unit 10 and the rear stage unit 20 will be described with reference to the flowcharts shown in FIGS. 12, 13, 14, and 15. The main control unit 10 and the prize ball control unit The process related to authentication with 204 is performed in the same procedure.

  FIG. 12 is a flowchart illustrating an example of processing related to authentication by the main control unit 10. The main control unit 10 waits until the control command transmission timing comes (step S61: NO). When the control command transmission timing comes (step S61: YES), the main control unit 10 determines the number of divisions (step S63). 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 S62). The value is subjected to encryption processing to generate individual authentication data (step S63). By this processing, individual test values and individual authentication data corresponding to the number of divisions are generated. Subsequently, the main control unit 10 acquires an operation inspection value (step S64), performs a predetermined calculation on the operation inspection value, and generates operation authentication data (step S65). The type (for example, the function number and the number of authentications) of the operation inspection value used for generating the operation authentication data is determined at the time of previous authentication data transmission.

  Next, the main control unit 10 adds the generated authentication data to the control command data (step S66), and transmits a control signal with authentication data to the effect control unit 203 (step S67). In the first embodiment, when the control command is transmitted, the control signal with authentication data is transmitted. However, the present invention is not limited to this. Even if the control signal with authentication data is mixed with the normal control signal and transmitted. Good. Further, the transmission order of the authentication data is also arbitrary. Although there are a plurality of individual authentication data, two or more individual authentication data may be added to one control command. When there is untransmitted authentication data among the generated authentication data, the main control unit 10 transmits a control signal with authentication data without newly generating authentication data even at a predetermined control command transmission timing. I do.

  After transmitting all the authentication data, the main control unit 10 determines whether the number of divisions determined in step S61 is a predetermined value (step S68). The predetermined value is, for example, an odd number (or even number). When the division number is a predetermined value (step S68: YES), the main control unit 10 switches the type of the operation inspection value used for generating the operation authentication data (step S69) and is one of the operation inspection values. The value of the number of authentications is incremented by 1 to update the value of the number of authentications (step S70), and the processing according to this flowchart ends. On the other hand, if the number of divisions is not a predetermined value (step S68: No), the value of the number of authentications is updated without switching the type of the operation inspection value (step S70), and the process according to this flowchart is terminated. Note that the process of updating the value of the number of times of authentication in step S70 may be a process performed after the process of acquiring the operation inspection value (step S64).

  Next, processing related to authentication by the latter stage unit 20 will be described. FIG. 13 is a flowchart illustrating an example of processing related to authentication by the rear-stage unit 20. First, the rear stage unit 20 stands by until receiving a control signal with authentication data as shown in FIG. 5 from the main control unit 10 via the effect control unit 203 (step S71: NO). When a control signal with authentication data is received from the main control unit 10 via the effect control unit 203 (step S71: YES), the rear stage unit 20 uses the individual authentication data 303 included in the received control signal with authentication data. The individual of the main control unit 10 is authenticated (step S72). Details of the individual authentication processing by the rear stage unit 20 will be described in detail with reference to FIG.

  When the authentication of the main control unit 10 with respect to the individual is successful (step S73: YES), the subsequent stage unit 20 authenticates the operation order of the main control unit 10 using the operation authentication data 304 (step S74). The post-stage unit 20 authenticates the operation order of the main control unit 10 based on whether or not the operation authentication data 304 matches the expected value for operation authentication (or has a predetermined relationship). Details of the operation authentication process performed by the rear stage unit 20 will be described in detail with reference to FIG.

  When the authentication with respect to the operation sequence of the main control unit 10 is successful (step S75: YES), the subsequent stage unit 20 authenticates that the received control signal is a correct signal (step S76). Further, the post-stage unit 20 determines whether or not the number of individual test values (joining number) subjected to the binary operation (see FIG. 13) when the authentication of the individual of the main control unit 10 is successful is a predetermined value. Judgment is made (step S77). When the number of connections is a predetermined value (step S77: YES), the main control unit 10 switches the expected value for operation authentication used for authentication of the operation authentication data (step S78), and ends the process according to this flowchart. On the other hand, if the number of connections is not a predetermined value (step S77: NO), the process according to this flowchart is terminated without switching the expected value for operation authentication.

  Further, when the authentication of the main control unit 10 with respect to the individual is not successful (step S73: NO), or when the authentication with respect to the operation sequence is not successful (step S75: NO), the rear stage unit 20 is connected to the main control unit 10. Authentication is not successful (step S79). If the authentication is not successful, the rear stage unit 20 generates an authentication failure signal based on the result of the authentication failure and transmits it to the effect control unit 203 (step S80), and ends the process according to this flowchart.

  Next, the individual authentication process (step S72 in FIG. 13) by the rear stage unit 20 will be described. FIG. 14 is a flowchart showing the procedure of the individual authentication process performed by the rear stage unit 20. In the flowchart of FIG. 14, the rear stage unit 20 waits until receiving the individual authentication data 303 (a control signal including the individual authentication data 303) (step S82: NO), and receives the individual authentication data 303 (step S82: YES), the individual authentication data 303 is decrypted to obtain the individual test value (step S83).

  The post-stage unit 20 stores the acquired individual test value in the individual test value memory (step S84), and performs a semi-group operation (joining process) on all the individual test values in the individual test value memory ( Step S85). If there is one test value in the individual test value memory, the process proceeds to step S86 without performing the combining process.

  Then, the post-stage unit 20 collates the operation result (combination result) of the combining process with the held expected value for individual authentication, and determines whether or not the combined result matches the expected value for individual authentication. (Step S86). When the combined result matches the expected value for individual authentication (step S86: YES), the rear stage unit 20 makes the main controller 10 successfully authenticate the individual (step S87). Then, the data in the individual test value memory is erased (step S88), and the processing according to this flowchart is terminated.

  On the other hand, if the combined result and the expected value for individual authentication do not match in step S86 (step S86: NO), the rear stage unit 20 receives the predetermined number or more of individual authentication data 303 (step S89: NO). Returning to S82, the process of receiving and combining the individual authentication data 303 is repeated. When the individual authentication data 303 of a predetermined number or more is received (step S89: YES), the rear stage unit 20 makes the authentication of the main control unit 10 unsuccessful (step S90) and ends the processing according to this flowchart. The predetermined number is an arbitrary number within a range equal to or greater than the current division number and less than or equal to the number (maximum division number) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided.

  Next, the operation authentication process (step S74 in FIG. 13) by the rear stage unit 20 will be described. FIG. 15 is a flowchart illustrating the procedure of the operation authentication process performed by the rear-stage unit 20. In the flowchart of FIG. 15, the rear stage unit 20 waits until a control signal including the operation authentication data 304 is received (step S91: NO), and receives a control signal including the operation authentication data 304 (step S91: YES). The operation authentication data 304 is acquired (step S92), and the acquired operation authentication data 304 is stored in the operation authentication data memory (step S93).

  Then, the post-stage unit 20 compares the operation authentication data 304 with the stored operation authentication expected value, and determines whether or not the operation authentication data 304 matches the operation authentication expected value (step S94). ). When the operation authentication data 304 matches the expected value for operation authentication (step S94: YES), the rear stage unit 20 makes the authentication for the operation of the main control unit 10 successful (step S95). Then, the data in the memory for operation authentication data is erased (step S96), and the value of the expected value for operation authentication (number of authentications) is updated by adding 1 to the value of the number of authentications that is one of the expected values for operation authentication. (Step S97), and the process according to this flowchart is terminated.

  On the other hand, when the operation authentication data 304 and the expected value for operation authentication do not match in step S94 (step S94: NO), the rear-stage unit 20 makes the authentication for the operation of the main control unit 10 unsuccessful (step S98). The value of the number of times of authentication, which is one of the expected values for authentication, is incremented by 1 to update the value of the expected value for operation authentication (number of times of authentication) (step S97), and the processing according to this flowchart ends. Note that the process for updating the expected value for operation authentication in step S97 may be a process performed after the process for verifying the operation authentication data and the expected value for operation authentication (step S94).

  As described above, the individual authentication process such as the decryption of the individual authentication data, the collation between the individual test value and the expected value for individual authentication, and the operation authentication process such as the collation between the operation authentication data and the expected value for operation authentication include Since only this is executed, the processing load on the CPU 203a constituting the effect control unit 203 does not increase. For this reason, it is possible to prevent problems such as a reduction in the processing speed of the effect control unit 203 and a smooth display for the effect.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 16 is a flowchart illustrating an example of processing related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether or not a control signal has been received from the main control unit 10 (step S101). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the main control part 10, the judgment result of step S101 will be "YES", and the production | presentation control part 203 will progress to step S102.

  In step S102, the effect control unit 203 transmits the received control signal as it is to the subsequent stage unit 20, and proceeds to step S103. In step 103, the effect control unit 203 starts processing based on the control command data 301 and the accompanying data 302, and proceeds to step S104.

  In step S <b> 104, the effect control unit 203 determines whether or not the authentication unsuccessful signal transmitted from the subsequent unit 20 has been received. When the authentication unsuccessful signal has not been received from the rear stage unit 20 (step S104: NO), the effect control unit 203 determines that the main control unit 10 has been successfully authenticated in the rear stage unit 20, and the process according to this flowchart. Exit.

  On the other hand, when the authentication failure signal is received from the rear stage unit 20 (step 104: YES), the effect control unit 203 determines that the main stage control unit 10 has not been successfully authenticated in the rear stage unit 20, and step S103. The process based on the control command data 301 and the accompanying data 302 started in the process is interrupted, and a notification signal for notifying fraud is sent to the center that manages the symbol display unit 104, the lamp control unit 205, or the pachinko gaming machine 1. After transmitting to the control device or the like (step S105), the processing according to this flowchart is terminated.

  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.

  When the production control unit 203 receives the authentication unsuccessful signal, the production control unit 203 interrupts the process based on the control command and transmits a notification signal for notifying the fraud. However, it only transmits a notification signal for notifying the fraud. But you can.

  Next, a specific example of the process of switching the type of operation inspection value used for generating operation authentication data among the processes shown in FIGS. 12 to 15 will be described. FIG. 17 is a sequence diagram illustrating an example of a data flow between control units. In FIG. 17, there are two types of operation inspection values, value A (number of authentications) and value B (function number), and the operation inspection value used for generating operation authentication data when the number of divisions (number of connections) is an odd number. It is assumed that the type of is switched. The default operation inspection value is assumed to be value A. In the first embodiment, the post-stage unit 20 receives the authentication data transmitted by the main control unit 10 via the peripheral unit 30 (the effect control unit 203). However, in the sequence diagram of FIG. Therefore, the description of the processing of the peripheral part 30 is omitted.

  First, the main control unit 10 determines the number of divisions used for the current authentication process by an arbitrary method. For example, assuming that the current number of divisions = 3 (step S111), the main control unit 10 divides the data stored in the program code storage area 400 into three blocks, and uses the data included in each block. A group operation is performed to calculate three individual test values, and an encryption process is further performed to generate individual authentication data (step S112).

  Further, the main control unit 10 acquires the number of times authentication processing is executed (authentication number: value A) as an operation inspection value (step S113), and generates operation authentication data (step S114). Then, the main control unit 10 transmits an authentication data-added control signal including individual authentication data and operation authentication data to the rear stage unit 20 via the effect control unit 203 (step S115).

  Thereafter, the main control unit 10 switches the type of the operation inspection value used for generating the operation authentication data because the current division number is an odd number (step S116). Specifically, the operation inspection value used for generating the operation authentication data is switched from the value A to the value B. Then, the main control unit 10 updates the value of the number of authentications by adding 1 to the value of the number of authentications that is one of the operation inspection values (Step S117).

  Next, processing in the rear stage unit 20 will be described. The rear stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S118). Then, the individual authentication data is extracted from the control signal with authentication data, decrypted to obtain the individual test value, the combined test is performed on the acquired individual test value (step S119), and the combined result is used for the individual authentication. Check against the expected value. When the combined result matches the expected value for individual authentication, the rear stage unit 20 makes the authentication of the main control unit 10 successful for the individual (step S120). In this case, when the combination process is performed using three individual test values, it matches the expected value for individual authentication (number of connections = 3).

  Further, the post-stage unit 20 extracts the operation authentication data from the control signal with authentication data, and collates it with the expected value for operation authentication (step S121). At this time, the post-stage unit 20 uses the operation authentication expected value (expected value A) corresponding to the value A to collate with the operation authentication data. When the operation authentication data matches the expected value for operation authentication, the rear stage unit 20 succeeds in authenticating the operation sequence of the main control unit 10 (step S122). The latter stage unit 20 updates the value of the expected value for operation authentication (number of authentications) by adding 1 to the value of the number of times of authentication that is one of the expected values for operation authentication (step S123). Then, since the number of couplings this time is an odd number, the rear stage unit 20 switches the expected value for operation authentication (step S124). Specifically, the expected value for operation authentication is switched from expected value A to expected value B (expected value for operation authentication corresponding to value B). This is the flow of a series of switching processes.

  Turning to the description of the second process, the main control unit 10 again determines the number of divisions by an arbitrary method. For example, assuming that the current number of divisions = 4 (step S125), the main control unit 10 divides the data stored in the program code storage area 400 into four blocks, and uses the data contained in each block to 4 One individual test value is calculated, and further calculation is performed to generate individual authentication data (step S126).

  Further, the main control unit 10 acquires the function number (value B) of the process being executed as the operation check value (step S127), and generates operation authentication data (step S128). Then, the main control unit 10 transmits an authentication data-added control signal including individual authentication data and operation authentication data to the rear stage unit 20 via the effect control unit 203 (step S129). Thereafter, since the current division number is an even number, the main control unit 10 continues the value B without switching the type of the operation inspection value used for generating the operation authentication data (step S130). Then, the main control unit 10 updates the value of the number of times of authentication by adding 1 to the value of the number of times of authentication that is one of the operation inspection values (step S131).

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S132), acquires the individual test value from the individual authentication data, and combines it with the acquired individual test value. Processing is performed (step S133). When the combined result matches the expected value for individual authentication, the rear stage unit 20 makes the authentication of the main control unit 10 successful for the individual (step S134). In this case, when the combination process is performed using the four individual test values, it matches the expected value for individual authentication (number of connections = 4).

  Further, the post-stage unit 20 extracts the operation authentication data from the control signal with authentication data, and collates it with the expected value for operation authentication (step S135). At this time, the post-stage unit 20 performs collation with the operation authentication data using the operation authentication expected value (expected value B) corresponding to the value B. When the operation authentication data matches the expected value for operation authentication, the rear-stage unit 20 succeeds in authenticating the operation sequence of the main control unit 10 (step S136). The rear stage unit 20 updates the value of the expected value for operation authentication (number of authentications) by adding 1 to the value of the number of times of authentication that is one of the expected values for operation authentication (step S137). Then, since the number of couplings this time is an even number, the rear stage unit 20 does not switch the expected value for operation authentication and continues with the expected value B (step S138).

  In the pachinko gaming machine 1 according to the first embodiment, the main control unit 10 divides a predetermined program code stored in the ROM 10b, and generates the operation authentication data at the next authentication based on the number of divisions ( The type of operation inspection value used for generating operation authentication data is changed. Since the number of divisions is a value that only the main control unit 10 knows, the fraudster cannot know the change timing of the type of the operation inspection value used for generating the value of the operation authentication data. For this reason, it is possible to detect the cheating and the malfunction of the gaming machine.

The individual authentication process using the individual authentication data may be performed every time the individual authentication data is received, but is not limited thereto, and may be performed when a plurality of individual authentication data is received. In this case, for example, when receiving the first individual authentication data together with the first control command data and the first accompanying data of the first control command, the rear-stage unit 20 performs the control command without performing the individual authentication process. The processing based on the first control command data and the first associated data is performed. Then, when the second-stage unit 20 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, an authentication process using the first individual authentication data is performed. At this time, the post-stage unit 20 may perform the individual authentication process using both the first individual authentication data and the second individual authentication data.
Further, the individual authentication data 303 may be generated including the control command data 301 and the accompanying data 302 transmitted this time. This prevents the unauthorized use of the individual authentication data 303 by the main control unit, can more reliably detect fraud and malfunctions, and prevent execution of unauthorized control commands due to fraud and malfunctions. can do.

Further, in the pachinko gaming machine 1 according to the first embodiment, since the rear stage unit 20 that executes the authentication process and the effect control unit 203 that mainly executes the effect process are independent, the authentication program and the effect It can be designed separately from the program for As a result, compared with the case where an authentication function is added to the production process of the production control unit 203, it is easier and less time-consuming to design, implement the function, verify the function, etc. when adding the authentication function. Can do.
Further, in the configuration in which the effect control unit 203 performs both the authentication process and the effect process as in the past, the following (a) to (c) that occur when it is necessary to change the design of any one of the above programs ) Will not occur.

(A) Since the program becomes complicated, it becomes difficult to maintain consistency with other functions (in this case, an unexpected error may occur).
(B) Although the authentication process can be made common even if the model of the pachinko gaming machine 1 is different, the production process is often different for each model of the pachinko gaming machine 1. Therefore, it is necessary to design the entire program of the processing executed by the effect control unit 203 including the authentication processing that can be shared for each model of the pachinko gaming machine 1, and the design takes a lot of time and the work efficiency is improved. bad.
(C) When the authentication algorithm for authentication is changed, the processing in the peripheral part that performs the predetermined processing must be changed. Due to this change, it takes a lot of time and labor to verify whether or not the desired authentication function can be obtained, and there is a problem that it takes a lot of time and effort to develop a gaming machine. It cannot be changed easily.

  Furthermore, in this Embodiment 1, since the back | latter stage part 20 is provided in the back | latter stage of the production | presentation control part 203, the difference of the processing capability between CPU10a which comprises the main control part 10, and CPU203a which comprises the production | generation control part 203 In addition, a difference in storage capacity between the ROM 10 b constituting the main control unit 10 and the ROM 203 b constituting the effect control unit 203 can be absorbed by the rear stage unit 20. 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 constituting the main control unit 10 are the processing capacity of the CPU 203 a constituting the effect control unit 203 and the storage capacity of the ROM 203 b constituting the effect control unit 203. When there is a margin in comparison, the main control unit 10 transmits the individual authentication data 303 obtained by performing complex or advanced encryption processing to each individual test value to the rear stage unit 20, and the rear stage unit 20 receives it. An authentication success signal or authentication obtained by subjecting the authentication result obtained by authenticating the main control unit 10 using each individual test value obtained from the individual authentication data 303 to a relatively simple or low level encryption process A failure signal (hereinafter referred to as an authentication success signal or the like) is transmitted to the effect control unit 203. Then, the production control unit 203 performs processing according to the authentication result obtained from the authentication success signal or the like. By configuring in this way, even if a complicated or advanced authentication method is not used, if an authentication process using a relatively simple authentication method is performed, the main control unit 10 and the latter part 20 and the latter part A high security level can be maintained between 20 and the effect control unit 203.

  Further, the processing capacity of the CPU 203 a configuring the effect control unit 203 and the storage capacity of the ROM 203 b configuring the effect control unit 203 are the processing capacity of the CPU 10 a configuring the main control unit 10 and the storage capacity of the ROM 10 b configuring the main control unit 10. If there is room for comparison, the main control unit 10 uses the individual authentication values 303 as the individual authentication data 303 as they are, or the individual authentication data 303 obtained by performing relatively simple or low-level encryption processing on the subsequent stage unit 20. The post-stage unit 20 performs complex or advanced re-encryption processing on the authentication result obtained by authenticating the main control unit 10 using each individual test value obtained from the received authentication data 303, or the authentication An authentication success signal or the like obtained by performing a decoding process or the like on each individual test value obtained from the data 303 is transmitted to the effect control unit 203. Then, the production control unit 203 performs processing according to the authentication result obtained from the authentication success signal or the like. By configuring in this way, even if a complicated or advanced authentication method is not used, if an authentication process using a relatively simple authentication method is performed, the main control unit 10 and the latter part 20 and the latter part A security level can be maintained as much as possible between 20 and the effect control unit 203.

  This is not only the case where there is a difference in the processing capacity of the CPUs 10a and 203a and the storage capacities of the ROMs 10b and 203b constituting the main control unit 10 and the effect control unit 203, respectively, but there is no such difference. When all or part of one of the programs executed by the CPU 10a constituting the main control unit 10 or the CPU 203a constituting the effect control unit 203 is changed (for example, version upgrade), each individual test value or intermediate calculation result The same applies to a case where a formal difference occurs between the main control unit 10 and the effect control unit 203 in the data structure or the like.

<Embodiment 2>
Hereinafter, a pachinko gaming machine according to Embodiment 2 of the present invention will be described. The pachinko gaming machine according to the second embodiment is different from the pachinko gaming machine according to the first embodiment in a method of dividing predetermined data stored in the ROM 10b in the main control unit 10 in advance. Other points are basically the same as those of the pachinko gaming machine of the first embodiment. 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.

Hereinafter, a predetermined data dividing method in the main control unit 10 will be described in detail.
The main control unit 10 determines the amount of data (hereinafter referred to as data amount) constituting each data block that is a target for generating individual test values. The data amount determination method is, for example, a method in which a value generated by a random number generation circuit (not shown) or a random number generation program constituting the program code is used as the data amount, or in other processing of the main control unit 10 A method is conceivable in which a generated value is referred to at a predetermined timing and the value is used as a data amount. For example, the main control unit 10 determines the data amount until the individual test value is generated using all of the predetermined program codes stored in the ROM 10b. The means for executing the processing for determining the data amount can correspond to, for example, the determination means 12 shown in FIG.

  Next, the main control unit 10 divides the predetermined program code in the ROM 10b by the data amount determined by the determination unit 12. Then, the main control unit 10 performs a semigroup operation for each data block, and generates individual test values for the number of divided data blocks for authenticating the main control unit 10. That is, in the second embodiment, the number of data blocks obtained by division is the number of divisions.

  For example, every time one individual test value is generated, the main control unit 10 determines the amount of data used for the generation. In this case, the main control unit 10 repeats the determination of the data amount and the generation of the individual test value until the generation of the individual test value using all the program codes in the predetermined area of the ROM 10b is completed. For this reason, in the second embodiment, how many individual test values are generated (that is, how many divisions are made) is determined by individual test values using all program codes in a predetermined area of the ROM 10b. Not sure until generation is complete.

  Instead of determining the data amount every time one individual test value is generated, the data amount used for generating the individual test value may be determined in advance. Further, the data amount used for generation of all individual test values may be made equal. In this case, the number of divisions can be predicted when the data amount is determined.

(Example of individual test value generation calculation)
An example in which the individual test value is generated by the method A using addition as the half-group operation will be described with reference to FIG. The program code storage area 400 shown in FIG. 4 stores 12 program codes (“0x01” to “0x09”, “0x0A” to “0x0C”, and the data amount of one program code is 1 byte). .
First, when the amount of data used to generate the first individual test value is determined to be 4 bytes, 4 bytes of program code (“0x01”, “0x02”) are determined from the program code stored in the program code storage area 400. , “0x03”, “0x04”) are divided into first blocks 400a. Next, the program codes “0x01”, “0x02”, “0x03”, and “0x04” stored in the first block 400a are added to obtain the first individual test value “0x0A”.

  Subsequently, when the data amount used to generate the second individual test value is determined to be 3 bytes, the program code stored in the first block 400a is excluded from the program codes stored in the program code storage area 400. A 3-byte program code (“0x05”, “0x06”, “0x07”) is divided from the program code to form a second block 400b. Next, the program codes “0x05”, “0x06”, “0x07” stored in the second block 400b are added to obtain the second individual test value “0x12”.

  Subsequently, when the data amount used to generate the third individual test value is determined to be 7 bytes, the program code stored in the program code storage area 400 is stored in the first block 400a and the second block 400b. Since the program code excluding the program code has only 5 bytes, the program code of 5 bytes (“0x08”, “0x09”, “0x0A”, “0x0B”, “0x0C”) is defined as the third block 400c. . Next, the third individual test value “0x32” is obtained by adding the program codes “0x08”, “0x09”, “0x0A”, “0x0B”, “0x0C” stored in the third block 400c. Since the main control unit has generated the individual test value using all the 12 program codes stored in the program code storage area 400, the main control unit ends the generation of the individual test value.

  Hereinafter, a process related to authentication in the main control unit will be described. FIG. 18 is a flowchart illustrating an example of processing related to authentication by the main control unit. In this flowchart, a process when a data amount is determined and a predetermined program code is divided every time an individual test value is generated will be described. The main control unit 10 waits until the transmission timing of the control command is reached (step S141: NO). When the transmission timing of the control command is reached (step S141: YES), the individual control value that is the basis of the individual authentication data is generated. The data amount of the program data used for is determined (step S142). Note that the data amount may be determined before the transmission timing of the control command.

  Next, the main control unit 10 reads the amount of program data determined in step S142 from the top of the program code storage area 400, for example, and performs a semi-group operation on the read data to calculate an individual test value. (Step S143) The individual inspection value is encrypted to generate individual authentication data (Step S144).

Until the individual test value is generated using all the data in the program code storage area 400 (step S145: NO), the main control unit 10 returns to step S142 and repeats the subsequent processing. Here, “using all the data in the program code storage area 400” means that all the data in the program code storage area 400 is used without duplication. When generating the second and subsequent individual test values, the main control unit 10, for example, writes the data written in the area next to the program data used for the previous individual test value generation by the amount determined in step S142. Read and generate individual test values. Note that when generating the last individual test value, the data amount determined in step S142 may be insufficient, but the main control unit 10 generates the individual test value using only the program data that can be acquired. To do. By this process, the number of generated individual test values (individual authentication data) becomes the division number.
When the main control unit 10 does not generate the inspection value using all the data (step S145: NO), the main control unit 10 always returns to step S142 regardless of whether or not it is the transmission timing of the control command. Determine the amount of data.

  Here, the control command for adding the authentication data is not particularly limited and may be an arbitrary control command. The control signal with authentication data may be transmitted continuously, or may be transmitted by mixing with a normal control signal. In addition, the authentication data is not transmitted immediately after it is generated, but is generated after all the authentication data is generated (that is, after the authentication data is generated using all the program codes in the program code storage area 400). Data transmission may be started.

  When the individual test value is generated using all the data in the program code storage area 400 (step S145: YES), the main control unit 10 acquires the operation test value (step S146), and the operation test value is obtained. A predetermined calculation is performed to generate operation authentication data (step S147). The type of operation inspection value used for generating operation authentication data is determined at the time of previous authentication data transmission. Note that the order of generation of individual authentication data and generation of operation authentication data may be interchanged.

  Next, the main control unit 10 adds the generated individual authentication data and operation authentication data to the control command (step S148), and transmits a control signal with authentication data to the rear stage unit 20 via the effect control unit 203 ( Step S149). In the second embodiment, the control signal with authentication data is transmitted when the control command is transmitted. However, the present invention is not limited to this, and the control signal with authentication data may be transmitted by mixing it with a normal control signal. Good. Further, the transmission order of the authentication data is also arbitrary. Although there are a plurality of individual authentication data, two or more individual authentication data may be added to one control command.

  After transmitting all the authentication data, the main control unit 10 determines whether the number of generated individual authentication data (individual test values), that is, the number of divisions is a predetermined value (step S150). The predetermined value is, for example, an odd number (or even number). When the division number is a predetermined value (step S150: YES), the main control unit 10 switches the type of the operation inspection value used for generating the operation authentication data (step S151), and is one of the operation inspection values. The value of the number of authentications is incremented by 1 to update the value of the number of authentications (step S152), and the processing according to this flowchart ends. On the other hand, if the number of divisions is not a predetermined value (step S150: NO), the value of the number of authentications is updated without switching the type of the operation inspection value (step S152), and the processing according to this flowchart is terminated. Note that the process of updating the value of the number of authentications in step S152 may be a process performed after the process of acquiring the operation inspection value (step S146).

  Processing related to authentication in the rear stage unit 20 and the effect control unit 203 is the same as that in the first embodiment. In other words, the post-stage unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data transmitted from the main control unit 10, performs authentication processing using these authentication data, and if the authentication is unsuccessful. An authentication failure signal is transmitted to the effect control unit 203. When the production control unit 203 receives an authentication failure signal from the rear stage unit 20, the production control unit 203 interrupts the processing based on the control command and transmits a notification signal.

  Next, a specific example of the process of switching the type of operation inspection value used for generating operation authentication data will be described. FIG. 19 is a sequence diagram illustrating an example of a data flow between control units. In FIG. 19, there are two types of operation inspection values, value A (number of authentications) and value B (function number), and the operation inspection value used for generating operation authentication data when the number of divisions (number of connections) is an odd number. It is assumed that the type of is switched. The default operation inspection value is assumed to be value A. In FIG. 19, for convenience of explanation, the data amount used for generating the individual test value is collectively determined. However, as shown in the flowchart of FIG. 18, the data amount is generated every time the individual test value is generated. May be determined. In the second embodiment, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the peripheral unit (the effect control unit 203), but the description is simplified in the sequence diagram of FIG. For the sake of simplicity, the description of the processing of the peripheral portion 30 is omitted.

  First, the main control unit 10 determines the data amount of program data used for generating an individual test value by an arbitrary method. For example, if the total amount of data is 12 bytes and the main control unit 10 determines the amount of data to be used for generating test values as 4 bytes, 5 bytes, and 3 bytes, respectively, three test values are generated and divided. Number = 3 (step S161). The main control unit 10 reads 4 bytes, 5 bytes, and 3 bytes of data in order from the top of the program code storage area 400, calculates three individual test values using the respective data, and further performs encryption processing. Individual authentication data is generated (step S162).

  Further, the main control unit 10 acquires the number of times authentication data is generated (operation number: value A) as an operation inspection value (step S163), and generates operation authentication data (step S164). Then, the main control unit 10 transmits an authentication data-added control signal including individual authentication data and operation authentication data to the rear stage unit 20 via the effect control unit 203 (step S165).

  Thereafter, the main control unit 10 switches the type of the operation inspection value used for generating the operation authentication data because the current division number is an odd number (step S166). Specifically, the operation inspection value used for generating the operation authentication data is switched from the value A to the value B. Then, the main control unit 10 updates the value of the authentication count by adding 1 to the value of the authentication count that is one of the operation inspection values (step S167).

  Next, processing in the rear stage unit 20 will be described. The rear stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S168). Then, the individual authentication data is extracted from the control signal with the authentication data, decrypted to obtain the individual test value, the combined test is performed on the acquired individual test value (step S169), and the combined result is used for the individual authentication. Check against the expected value. If the combined result matches the expected value for individual authentication, the rear stage unit 20 makes the main control unit 10 authenticate the individual successfully (step S170). In this case, when the combination process is performed using three individual test values, it matches the expected value for individual authentication (number of connections = 3).

  Further, the post-stage unit 20 extracts the operation authentication data from the control signal with authentication data, and collates it with the expected value for operation authentication (step S171). At this time, the post-stage unit 20 uses the operation authentication expected value (expected value A) corresponding to the value A to collate with the operation authentication data. When the operation authentication data matches the expected value for operation authentication, the rear-stage unit 20 succeeds in authenticating the operation sequence of the main control unit 10 (step S172). The rear stage unit 20 updates the value of the expected value for operation authentication (number of authentications) by adding 1 to the value of the number of times of authentication that is one of the expected values for operation authentication (step S173). Then, since the number of couplings this time is an odd number, the rear stage unit 20 switches the expected value for operation authentication (step S174). Specifically, the expected value for operation authentication is switched from expected value A to expected value B (expected value for operation authentication corresponding to value B). This is the flow of a series of switching processes.

  Turning to the description of the second processing, the main control unit 10 again determines the data amount of the program code used for generating the individual test value by an arbitrary method. For example, when the main control unit 10 determines the data amount used for generating the individual test value as 2 bytes, 3 bytes, 4 bytes, and 3 bytes, respectively, four test values are generated, and the division number = 4. (Step S175), the main control unit 10 reads out data of 2 bytes, 3 bytes, 4 bytes, and 3 bytes in order from the top of the program code storage area 400, and calculates four individual test values using each data. Then, further computation is performed to generate individual authentication data (step S176).

  Further, the main control unit 10 acquires the function number (value B) of the process being executed as the operation inspection value (step S125), and generates operation authentication data (step S178). Then, the main control unit 10 transmits an authentication data-added control signal including the individual authentication data and the operation authentication data to the rear stage unit 20 via the effect control unit 203 (step S179). Thereafter, since the current division number is an even number, the main control unit 10 continues the value B without switching the type of the operation inspection value used for generating the operation authentication data (step SS180). Then, the main control unit 10 updates the value of the number of authentications by adding 1 to the value of the number of authentications that is one of the operation inspection values (step S181).

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S182), acquires the individual test value from the individual authentication data, and combines it with the acquired individual test value. Processing is performed (step S183). When the combined result matches the expected value for individual authentication, the rear stage unit 20 makes the main control unit 10 successfully authenticate the individual (step S184). In this case, when the combination processing is performed using the four individual test values, it matches the expected value (number of connections = 4).

  Further, the post-stage unit 20 extracts the operation authentication data from the control signal with authentication data, and collates it with the expected value for operation authentication (step S185). At this time, the post-stage unit 20 performs collation with the operation authentication data using the operation authentication expected value (expected value B) corresponding to the value B. When the operation authentication data matches the expected value for operation authentication, the rear stage unit 20 makes the authentication for the operation sequence of the main control unit 10 successful (step S186). The latter stage unit 20 updates the value of the expected value for operation authentication (number of authentications) by adding 1 to the value of the number of times of authentication that is one of the expected values for operation authentication (step S187). Then, since the number of couplings this time is an even number, the rear stage unit 20 does not switch the expected value for operation authentication and continues with the expected value B (step S188).

  As described above, in the pachinko gaming machine according to the second embodiment, the main control unit does not determine the division number itself, but determines the data amount used for generating the authentication data. For this reason, the possibility that the number of divisions is illegally stolen can be reduced. In the second embodiment, the effects obtained by the first embodiment are naturally obtained.

<Embodiment 3>
In the said Embodiment 1, 2, although the example which set the back | latter stage part 20 and the production | presentation control part 203 as a separate hardware structure was shown, it is not limited to this.
For example, with respect to the first embodiment, one CPU has the functions of the CPU 20a constituting the rear stage unit 20 and the function of the CPU 203a constituting the presentation control unit 203, and the rear stage 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 and reception of data, a control signal with authentication data, and the like between the rear stage unit 20 and the production control unit 203 function as a work area of the RAM 20c constituting the rear stage unit 20 and the production control unit 203, for example. 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. Therefore, for example, it is conceivable to perform processing of the rear stage unit 20 with a dual CPU configuration.

  In the pachinko gaming machine according to the third embodiment, since the rear stage and the production control unit are configured by a single piece of software, the following effects can be obtained in addition to the effects obtained in the first and second embodiments.

1. Parallel development and information security improvement When the production control unit and the latter part are separated and independent on the software configuration, the production control unit and the latter part can be developed separately in parallel, for example, The following effects can be obtained.

[1] Since the production control unit and the rear stage 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 impossible.
[2] Since it is possible to take independent development systems for the production control unit and the latter part, confidential business information (for example, an authentication processing method, etc.) when performing design and manufacturing verification of the production control unit and the latter part , Processing related to games, etc.) can be reduced out of the development system.

2. Ease of introduction of authentication function and ease of porting to other models Since the authentication process in the latter part is independent of the existing game process, the transmission of authentication information between the authentication process in the latter part and the existing game process is It can be performed using an interface provided for existing game processing. Therefore, it becomes easy to introduce an authentication function.

  In addition, when designing, developing, and verifying a new model of a gaming machine, there is a high possibility that the difference between the function of the new model of the gaming machine and the function of the previous model is not so much related to the mounting of the subsequent stage. Therefore, there is a high possibility that the design change will be minimal when the transition from the previous model to the new model is performed for the rear stage.

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

4). Ease of change of authentication method When changing the authentication method or upgrading the authentication algorithm, it is sufficient to change or upgrade only the main control unit and the latter part, and change the processing related to the authentication of the production control unit. No need.

5). 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.

6). Reducing the processing load of the production control unit When the authentication function to be implemented in the latter stage unit is implemented with the software of the production control unit, the processing load on the production control unit increases by adding an authentication function to the existing game processing of the production control unit Will do. 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 back | latter stage part 20 in the back | latter stage of the production | presentation control part 203 was shown, it is not limited to this, You may provide a back | latter stage part in the back | latter stage of the prize ball control part 204. 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 transmit data indicating that the authentication has failed together with the control command data 301 and the accompanying data 302 to the main control unit 10. Then, the main control unit 10 transmits the data indicating the failure to the effect control unit 203, and the effect control unit 203 performs an illegal act based on the data indicating the failure. Let them know.
In each of the above-described embodiments, the rear stage unit 20 is configured to include a CPU, a ROM, a RAM, and the like, but may be realized as an integrated circuit such as an LSI having the same function.

  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. You may make it produce | generate, add to a control command, and may be transmitted to the back | latter stage part 20 via the production | presentation control part 203. FIG. In this case, the subsequent stage 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 number in this way, the subsequent stage unit 20 restores the operation check value from the received operation authentication data, and determines whether or not the value of the operation check value is continuous in the order received. It can be performed. In other words, the post-stage unit 20 does not need to store the operation authentication test value in advance or perform the verification process using the operation authentication data and the expected value for operation authentication in order to perform the operation authentication. Accordingly, it is possible to reduce the processing load due to the operation authentication of the rear stage unit 20 and the data amount related to the operation authentication that occupies the storage area of the rear stage unit 20.

  Moreover, in the pachinko gaming machine according to the first to third embodiments, the function number and the number of authentications are illustrated as the operation inspection value, but the number of transmissions of the control command may be used as the operation inspection value. In this case, the post-stage unit 20 may perform the authentication process using the number of received control commands, that is, the number of control command receptions as an expected value for operation authentication. When the control command transmission timing comes, the main control unit 10 updates the value of the control command transmission count stored in the operation test value storage area of the RAM 10c by +1, and uses the updated transmission count as the operation test value. get. The main control unit 10 performs a predetermined operation on the acquired operation inspection value to generate operation authentication data, adds the generated operation authentication data to the control command, and transmits it to the subsequent stage unit 20 via the effect control unit 203. To do. When receiving the control command to which the operation authentication data is added, the rear stage unit 20 extracts the operation authentication data, updates the operation authentication expected value stored in the RAM 20c by +1, and extracts the extracted operation authentication data. And perform the operation authentication using the updated expected value for operation authentication.

  Further, the number of individual test values generated by the main control unit 10 (that is, the total number of divisions) may be used as the operation test value. In this case, the post-stage unit 20 may perform authentication processing using the number of individual authentication data transmitted from the main control unit 10 via the effect control unit 203 (that is, the total number of connections) 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. When it is time to update the expected value for operation authentication, the subsequent stage unit 20 adds the number of pieces of individual authentication data subjected to the current individual authentication process to the value of the expected value for operation authentication stored in the RAM 20c (that is, this time The expected value for operation authentication is updated.

  In the pachinko gaming machine according to the first to third embodiments, the individual authentication data may be generated using part or all of the operation authentication data. Specifically, the main control unit 10 generates operation authentication data before generating individual authentication data. Next, the main control unit 10 generates a plurality of individual test values, performs encryption processing on the generated plurality of individual test values, and generates individual authentication data. Any one of them and a part or all of the operation authentication data are encrypted together to generate individual authentication data. The operation authentication data used for generating the individual authentication data is determined by a predetermined determination method. In this case, the post-stage unit 20 determines the operation authentication data used for generating the individual authentication data from the received operation authentication data by the same predetermined determination method as the main control unit 10, and the determined operation authentication data and the storage unit 11. Individual authentication may be performed using a value obtained by performing a semi-group operation in combination with predetermined data stored in the data as an individual authentication test value. Thus, by generating individual authentication data using a part or all of the operation authentication data, even when the operation authentication data is reused by an unauthorized control unit, during the individual authentication process, Since the operation authentication data is not consistent, fraud can be detected. Further, even if the operation authentication data is changed due to a malfunction, since the authentication is not successful, it is possible to prevent malfunction caused by the noise or the like.

  Moreover, in the pachinko gaming machine according to the first to third embodiments, the operation authentication data may be generated using a part or all of the individual authentication data. Specifically, the main control unit 10 generates individual authentication data before generating the operation authentication data. Next, when the main control unit 10 acquires an operation test value and performs a predetermined operation on the acquired operation test value to generate operation authentication data, a part or all of the operation test value and the individual authentication data In addition, encryption processing is performed to generate operation authentication data. The individual authentication data used for generating the operation authentication data is determined by a predetermined determination method. In this case, the post-stage unit 20 determines the individual authentication data used for generating the operation authentication data from the received individual authentication data by the same predetermined determination method as that of the main control unit 10, and calibrates using the determined individual authentication data. The operation authentication may be performed using the expected value for operation authentication. Thus, by generating the operation authentication data using a part or all of the individual authentication data, even when the individual authentication data is reused by an unauthorized control unit, during the operation authentication process, The identity authentication data cannot be matched, and fraud can be detected. Further, even if the individual authentication data is changed due to a malfunction, since the authentication is not successful, it is possible to prevent malfunction caused by the noise or the like.

  Moreover, although the pachinko gaming machine according to the first to third embodiments has been described as adding at least one of individual authentication data and operation authentication data to the control command when transmitting the control command, the game according to the present invention The machine is not limited to this. The main control unit 10 may output a control signal with authentication data (or a control signal with individual authentication data and a control signal with operation authentication data, the same applies hereinafter) at an arbitrary timing. For example, a control signal with authentication data may be output every predetermined time. However, when individual authentication data and operation authentication data are transmitted separately (when a control signal with authentication data and a control signal with operation authentication data are transmitted respectively), the individual authentication data is generated using the operation authentication data. In this case, it is necessary to transmit the operation authentication data before the individual authentication is performed. Similarly, when the operation authentication data is generated using the individual authentication data, it is necessary to transmit the individual authentication data before the operation authentication is performed.

  Further, in the pachinko gaming machine according to the first to third embodiments, at least one of individual authentication data and operation authentication data is added to the control command only when transmitting a predetermined control command, for example, a predetermined control command. May be transmitted. In this case, the main control unit 10 determines whether or not the control command is a predetermined control command, and an authentication in which at least one of individual authentication data and operation authentication data is added to the control command only when the control command is a predetermined control command. A control signal with data is transmitted to the rear stage unit 20 via the effect control unit 203, and a normal control signal is transmitted to the rear stage unit 20 via the effect control unit 203 when the control command is other than a predetermined control command. Further, the post-stage unit 20 determines whether or not the control command is a predetermined control command, or determines whether or not at least one of individual authentication data and operation authentication data is added to the control command. When the normal control signal is transmitted, the rear stage unit 20 transmits the normal control signal to the effect control unit 203 as it is, and the effect control unit 201 performs processing based on the received normal control signal.

  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 part to execute the process of reaching the jackpot, a power-on command for causing the peripheral part to execute a power-on process, and a demonstration display in the non-game state on the peripheral part A customer waiting demo command to be executed, a customer waiting demo stop command to stop the demonstration display in the non-gaming state in the peripheral part, and a quit command to cause the peripheral part to execute processing when the lottery result at the lottery is off , Like the open lottery of ordinary electric accessories (electric tulips) and the jackpot called the so-called fake It refers to such small hit command transmitted for the duration of the small contact state such as another electric combination thereof is opened for a short time. 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 effect control unit 203 increases by performing the authentication process only during a period in which the control command data 301 of a predetermined control command is received. The rate at which the processing load of the unit 203 increases can be suppressed.

  Further, since the authentication data 303 is added only to the control command data 301 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 effect control unit 203. Accordingly, since it is not necessary to design a new timing for the entire program executed by the effect control unit 203, an authentication function is added as compared with the case where the authentication data 303 is added to the control command data 301 of all control commands. Designing timing, implementing functions, verifying functions, etc. can be achieved more easily and with less work man-hours.

  In addition, the main control unit 10 transmits at least one of the individual authentication data 303 and the operation authentication data to the control command data 301 only when transmitting control command data of a predetermined control command to the subsequent stage unit 20 via the effect control unit 203. Add one. That is, since the authentication process is performed only when the control command data of the predetermined control command is transmitted, the rate at which the processing load of the main control unit 10 and the effect control unit 203 increases due to the authentication process can be suppressed. 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.

  In this way, the main control unit 10 adds the authentication data 303 to the control command data 301 only when transmitting control command data of a predetermined control command to the subsequent stage unit 20 via the effect control unit 203. That is, since the authentication process is performed only when the control command data of the predetermined control command is transmitted, the rate at which the processing load of the main control unit 10 and the effect control unit 203 increases due to the authentication process can be suppressed. 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 303 is extracted from the control signal can be reduced. Further, even if the authentication data 303 is extracted from the control signal, the number of samples that can be acquired is small, so that the risk of the authentication data 303 being 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 when the main control unit 10 and the effect control unit 203 do not have a high processing capacity, or even in the pachinko gaming machine 1 with a large processing load of game-related processing, an authentication processing function can be added. it can. 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.

  Further, the post-stage unit 20 transmits an authentication success signal including an authentication unsuccessful signal only in the case of a predetermined control command. Since the authentication process of the main control unit 10 or the subsequent stage unit 20 is performed only when a predetermined control command is transmitted, the rate at which the processing load of the effect control unit 203 increases due to the authentication process can be suppressed.

By the way, when the main control unit 10 transmits at least one of the individual authentication data and the operation authentication data to the control command only when transmitting a predetermined control command, the effect control unit 203 performs normal control. A signal may be received. In this case, the effect control unit 203 may determine whether the control signal transmitted from the main control unit 10 is a normal control signal or a control signal with authentication data, and may perform processing based on each control signal. For example, when the control signal transmitted from the main control unit 10 is a normal control signal, the effect control unit 203 performs processing based on the control command as described above. In addition, when the control signal transmitted from the main control unit 10 is a control signal with authentication data, the effect control unit 203 transmits the control signal with authentication data to the subsequent unit 20 as it is. Note that authentication data may be extracted from the control signal with authentication data, and only the authentication data may be transmitted to the subsequent section 20.
In addition, the effect control unit 203 may determine whether the received control signal is a normal control signal or a control signal with authentication data, and may directly transmit all control signals to the rear stage unit 20. No. 20 may perform authentication processing when a control signal with authentication data is received.

  In addition, the pachinko gaming machine 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 expected value for individual authentication. It is not limited to. The main control unit 10 prepares a plurality of half-group operations in advance, and selects one half-group operation used for generating the next inspection value from the plurality of half-group operations based on the current number of divisions. The rear stage unit 20 may be configured to switch the individual authentication expected value based on the number of connections in response to the switching of the individual test value generation method in the main control unit 10. Specifically, for example, when the current division number is an odd number, the main control unit 10 selects the next half group calculation different from the currently used half group calculation, and when the current division number is an even number, The next half group calculation is the same as the half group calculation used this time. The rear stage unit 20 switches the individual test value generation method and the expected value for individual authentication when the number of divisions and the number of connections is odd, and generates the individual test value used previously when the number of divisions and the number of connections is even. Continue to use the method and expected values for individual authentication. In this case, the first half-group operation is set in advance so as to use the same method between the main control unit 10 and the subsequent stage unit 20. The number of divisions is a value that only the main control unit 10 knows, and the post-stage unit 20 can know the value as the number of connections only when the individual authentication is successful. Therefore, the fraudster cannot know the number of divisions and the number of connections, and cannot know the switching timing of the individual test value generation method. By changing the half-group operation and the expected value based on the number of divisions, it is possible to prevent an individual test value from being illegally generated by an unauthorized person.

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.
