(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. The peripheral unit performs the processing corresponding to the second key data on the second storage means for storing the second key data and the encrypted data received from the main control unit, thereby verifying the validity of the received encrypted data.

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.

  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 this noise, and the control 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.

To.

  According to the present invention, it is possible to detect fraudulent acts due to replacement of a regular main control board and an unauthorized main control board of a gaming machine or malfunction of the gaming machine, and to reduce the processing load on the peripheral CPU.

  Specifically, according to the present invention, the main control unit adds the inspection value obtained by the inspection value generation unit using the predetermined data stored in the data storage unit to the control command, and passes through the effect control unit. The latter part is added to the operation value obtained by performing the binary operation using the predetermined data stored in the data storage means of the main control unit and the predetermined control command. The main control unit is authenticated based on whether or not the calculation result obtained by performing the binary calculation using the inspection value matches. As a result, it is possible to detect the above-mentioned fraud and malfunction of the gaming machine, and it is possible to prevent the game store from being damaged due to an unreasonable amount of game media being paid out to the player.

  Specifically, according to the present invention, the main control unit adds the packet information included in the synchronization code to the control command as operation authentication data and transmits it to the subsequent unit via the effect control unit, The operation is authenticated by determining whether or not the packet information satisfies a predetermined correlation. As a result, it is possible to detect the above-mentioned fraud and malfunction of the gaming machine, and it is possible to prevent the game store from being damaged due to an unreasonable amount of game media being paid out to the player.

  Further, according to the present invention, since the authentication process is executed only by the subsequent stage part, it is possible to suppress an increase in the processing load of the CPU constituting the peripheral part. For this reason, it is possible to prevent the occurrence of problems such as the processing speed of the peripheral portion being reduced and the display for production not being performed smoothly.

  Furthermore, according to the present invention, since the latter part for executing the authentication process and the peripheral part for performing the predetermined process are separate and independent, the authentication program and the predetermined process program are designed separately. be able to. This makes it easier to design the timing for adding the authentication function, implement the function, verify the function, etc., compared to the case where the authentication function is added to the peripheral processing that performs the predetermined process Can be realized. In addition, since the configuration of the authentication program and the predetermined processing program is relatively simple, it is easy to maintain consistency with other functions.

  Furthermore, according to the present invention, even if the predetermined processing is different for each gaming machine model, the authentication process can be shared, so that the program design for each gaming machine model is easy, Design time can be shortened and work efficiency can be improved.

  Furthermore, according to the present invention, when the authentication algorithm for authentication is changed, it is only necessary to change the authentication program in the subsequent stage without changing the peripheral part for performing the predetermined processing. The authentication algorithm can be changed by man-hours.

  Furthermore, according to the present invention, the main control unit divides predetermined data and changes the type of packet information included in the synchronization code at a timing based on the number of divided data (number of divisions). Therefore, the latter part configures the operation authentication data at the next authentication processing at the timing based on the number of authentication data (number of couplings) subjected to the binary operation when the authentication to the main control unit is successful. Switch the type of packet information included in the synchronization code. Since the number of divisions is a value that only the main control unit can know, and the number of connections is a value that can be known only to the subsequent stage after successful authentication, the fraudster knows the switching timing of the type of the authentication data addition command. I can't. As a result, the possibility that the authentication data is illegally exploited can be reduced, and the accuracy of the authentication process between the main control unit and the subsequent stage unit can be improved. Malfunctions can be detected, and execution of unauthorized control commands due to these can be prevented.

(Main control unit)
The main control unit 10 includes a CPU 10a, a ROM 10b, a RAM 10c, a counter circuit (timer) (not shown), and the like. The CPU 10a controls basic operations related to the game of the pachinko gaming machine 1, and executes basic processing accompanying the progress of game contents based on a program (program code) stored in advance in the ROM 10b. In the ROM 10b, a program code for the CPU 10a to execute basic processing accompanying the progress of game contents of the pachinko gaming machine 1 is stored in advance. All or a part of the ROM 10b can correspond to, for example, the data storage unit 11 shown in FIG. The RAM 10c functions as a work area for data and the like in arithmetic processing performed when the CPU 10a executes basic processing accompanying the progress of game contents of the pachinko gaming machine 1. The counter circuit (timer) counts elapsed time.
The main control unit 10 performs a jackpot lottery when a game ball enters the first starting port 105 or the second starting port 120, and based on the lottery result, the effect stored in the ROM 10b. Select the command related to.

  On the input side of the main control unit 10, a first start port detection unit 221, a second start port detection unit 225, a gate detection unit 222, a normal winning port detection unit 223, and a first big winning port detection unit 214.

The first start port detection unit 221 detects that a game ball has entered the first start port 105 and transmits the detection result to the main control unit 10. The second start port detection unit 225 detects that a game ball has entered the second start port 120 and transmits the detection result to the main control unit 10. The gate detection unit 222 detects that the game ball has passed through the winning gate 106 and transmits the detection result to the main control unit 10.

Each said detection part can be comprised using a proximity switch etc., for example.

  Further, an accessory operating device 231 is connected to the output side of the main control unit 10. In the first embodiment, the accessory actuating device 231 opens and closes the first big prize opening opening / closing solenoid 109b and the second big prize opening opening / closing door 109a and the second big prize opening opening / closing door 129a, respectively. A solenoid 129b and a second start port opening / closing solenoid 120b for opening and closing the second start port 120 are configured.

  The accessory actuating device 231 is controlled by the main control unit 10 and energizes the first big prize opening / closing solenoid 109b to open the first big prize opening opening / closing door 109a or play a short hit game and small game during long play.

Opening and closing the start port 120.

  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 shown in [1] to [8] below, but the encryption processing shown in [3] is executed as necessary.

[1] Determination of the number of divisions The main control unit 10 determines the number of divisions, which is a number for dividing predetermined data stored in advance in the ROM 10b, for example, predetermined program codes (instruction codes and fixed data). Hereinafter, as an example of the predetermined data, description will be given using a predetermined program code. The main control unit 10 uses, for example, a value generated by a random number generation circuit (not shown) or a random number generation program constituting the program code as a division number, or a value generated in other processing of the main control unit 10. The value can be referred to at a predetermined timing and the value can be used as the division number. In this case, the upper limit of the number of divisions may be set in advance. The means for executing the process for determining the number of divisions can correspond to, for example, the determination means 12 shown in FIG. In the first embodiment, the main control unit 10 determines the number of divisions using random numbers, but this is an example for determining the number of divisions, and determines the number of divisions without using random numbers. You may make it do. For example, the main control unit 10 holds a table for determining the number of divisions in advance, and the main control unit 10 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 Inspection Value Next, the main control unit 10 divides the storage area in the ROM 10b in which a predetermined program code is stored in advance by the number of divisions determined in the process [1]. Then, the main control unit 10 performs a binary operation on the program code stored in each divided storage area of the ROM 10b, and generates test values for the number of divisions for authenticating the main control unit 10. To do. Note that the test value generation method (for example, the type of binary operation that satisfies the combining rule used for the test value generation) 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)

  Note that the main control unit 10 may be configured to select one half-group operation used for generation of the next inspection value from a plurality of half-group operations based on the current number of divisions. 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. Note that the first half-group operation is set in advance to use the same method between the main control unit 10 and the subsequent stage unit 20.

A method of generating each inspection value will be described with reference to FIG.
FIG. 4 is an explanatory diagram schematically showing a method for generating inspection values in the main control unit 10. The inspection 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 ( A 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 inspection value generation)
An example of the calculation for inspection 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 semi-group operation on the program code stored in each of these blocks to calculate a 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 inspection value “0x0A” is obtained by addition. Similarly, three program codes “0x05”, “0x06”, “0x07” stored in the second block 400b are added, and the second inspection value “0x12” is stored in the third block 400c. Program codes “0x08”, “0x09”, “0x0A”, “0x0B”, and “0x0C” are added to obtain a third inspection value “0x32”, respectively.

  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 inspection value“ 0x04 ”. Similarly, exclusive OR operation is performed on the three program codes “0x05”, “0x06”, “0x07” stored in the second block 400b, and the second check value “0x04” is stored in the third block 400c. A third check value “0x0C” is obtained by performing an exclusive OR operation on the five program codes “0x08”, “0x09”, “0x0A”, “0x0B”, and “0x0C”.

  In the first embodiment, as will be described later, the main control unit 10 sets predetermined data for authenticating the main control unit 10 when the output control command is a predetermined control command (for example, a jackpot command). Is added to data indicating the control command (control command data) and transmitted to the rear stage unit 20 via the effect control unit 203. Here, the data for authenticating the main control unit 10 added to the control command data will be collectively referred to as “authentication data”. Authentication data consists of data obtained by performing encryption processing on each inspection value or these inspection values, and data obtained by performing encryption processing on each synchronization code or these synchronization codes. It is. Hereinafter, in the present embodiment, the authentication data is described as data obtained by subjecting the inspection value to encryption processing, and data obtained by performing encryption processing on each synchronization code or these synchronization codes. However, the present invention is not limited to this, and processing related to authentication may be performed using the inspection value and the synchronization code itself as authentication data. In this case, it is not necessary to perform an encryption process on the check value in the main control unit 10, and it is not necessary to perform a decryption process on each authentication data when extracting the check value and the synchronization code in the subsequent stage unit 20. Processing can be simplified and increase in processing load can be suppressed.

  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.

  The means for executing the process for generating the inspection value can correspond to, for example, the inspection value generation means 13 shown in FIG.

[3] Generation of Individual Authentication Data The main control unit 10 performs an encryption process on each inspection value generated in the process [2], and adds individual authentication data to be added to predetermined control command data and accompanying data. Generate. 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 inspection value is transmitted to the subsequent stage unit 20 via the effect control unit 203, any processing is also performed. The possibility that each inspection value is analyzed by a fraudulent person can be reduced as compared with a case where each inspection 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 inspection value. Specifically, for example, a processing method for performing processing such as an error detection calculation for generating individual authentication data from each inspection value is made different. 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 each inspection value subjected to encryption processing, these four arithmetic operations or logical operations A process for rearranging the bit arrangement of the operation data obtained by the above, a process for shifting or rotating the bits of the operation data, and a plurality of bits constituting each inspection value subjected to the encryption process For example, a process of generating one piece of data in accordance with the above 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 inspection value “0x0A” shown in FIG. 4 will be described. As the encryption process, a process of adding control command data to the inspection 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 inspection 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 inspection value “0x0A”, “0xF8” is obtained. Next, by subtracting “0x03” from this “0xF8”, the value “0xF5” of the individual authentication data is obtained.
Similarly, if the authentication data is generated from the second inspection value “0x12” recorded in the program code storage area 400 shown in FIG. 4, the authentication data is generated from the value “0xF2” and the third inspection value “0x32”. 0x1D ".

  Note that the individual authentication data may be generated by performing an encryption process on the data including the inspection 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.

  Further, when including data related to control command data and accompanying data in the individual authentication data, the main control unit 10 performs encryption processing by combining the data related to the control command data and the accompanying data and the inspection value, thereby obtaining the individual authentication data. You may perform the process to produce | generate.

  The timing at which the main control unit 10 generates each test value and the timing at which individual authentication data is generated using each test value are not particularly limited, and control command data of a predetermined control command is transmitted. A program for performing processing for generating each test value and processing for generating individual authentication data using each test value may be incorporated into the control program of the main control unit so that the control program of the main control unit is generated.

[4] Acquisition of Synchronization Code The main control unit 10 selects the type of packet information used for acquisition of the synchronization code based on the number of divisions. Specifically, the main control unit 10 continuously outputs packet information (continuous packet information) with transmission of a control command, and packet information (every predetermined interval with transmission of a control command) ( The synchronization code is acquired using any one of (intermittent packet information).

  The continuous packet information is packet information output by at least two (two times) continuous timings generated by the main control unit 10. The output timing described here is an output timing corresponding to the processing speed of the main control unit 10. That is, if packet information can be output at every clock timing, every clock timing becomes an output timing, and if packet information can be outputted every 4 clock timings, every 4 clock timing becomes an output timing.

  The intermittent packet information is packet information that is output at least two (two times) output timings (output timings for each predetermined interval) among the packet information generated by the main control unit 10. The timing set at any given interval described here means, for example, intermittently continuous timing. For example, a clock timing such as every 1 clock timing or every 4 clock timings may be used as a reference, or a time such as 1 second or 0.5 seconds may be used as a reference.

  The main control unit 10 switches the type of packet information included in the synchronization code when the number of divisions is odd, and continues as it is when the number is even.

  When a synchronization code is acquired using continuous packet information, each packet information has a correlation at a predetermined interval. Therefore, the operation authentication means 23 can authenticate the continuity of the operation of the main control unit 10 by obtaining the correlation between a plurality of packet information.

  Further, when the synchronization code is acquired using the intermittent packet information, each packet information is transmitted at an arbitrary interval, for example, a predetermined time interval or a predetermined clock number interval with the transmission of the control command of the main control unit 10. Or at an output timing set at an interval of the number of instruction executions. For this reason, when packet information of continuous output timing is compared, the continuity of operation of the main control unit 10 is authenticated by obtaining a correlation between the packet information. As the synchronization code, values acquired as packet information may be used as they are, or values obtained by performing a predetermined operation on these values may be used.

  Even when a signal switching circuit or the like is mounted on an unauthorized control unit by confirming the operation sequence of the main control unit 10 using the synchronization code, the operation sequence authenticated by the synchronization code is not continuous. It can be determined that the control command is transmitted from an unauthorized control unit other than the control command transmitted from the control unit 10, and unauthorized control can be detected.

  The means for executing the process for acquiring the synchronization code can correspond to, for example, the synchronization code generation means 14 shown in FIG.

[5] Generation of operation authentication data The main control unit 10 performs an encryption process on each synchronization code acquired in the process [5], and adds operation authentication data to be added to predetermined control command data and accompanying data. Generate. 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 operation authentication data 304 obtained by performing encryption processing on each synchronization code is transmitted to the subsequent stage unit 20, each synchronization code that has not been subjected to any processing is directly processed in the subsequent stage. Compared with the case of transmitting to the unit 20, the possibility that each synchronization code is analyzed by an unauthorized person can be reduced.

  The main control unit 10 may perform different encryption processing on each synchronization code. Specifically, for example, a processing method for performing processing such as error detection calculation for generating operation authentication data from each synchronization code is made different.

  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 respective synchronization codes subjected to encryption processing, these four arithmetic operations or logical operations A process for rearranging the bit sequence of the operation data obtained by the above, a process for shifting or rotating the bits of the operation data, and a plurality of bits constituting each synchronization code subjected to the encryption process For example, a process of generating one piece of data in accordance with the above 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 to be used for generating the next operation 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.

[6] Data addition to control signal The main control unit 10 adds individual authentication data and operation authentication data to control command data transmitted to the rear stage unit 20 via the effect control unit 203 and accompanying data described later. To generate a control signal with authentication data.

[7] 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. As shown in FIG. 5 (1), the normal control signal 300 output from the main control unit 10 includes control command data 301 and accompanying data 302. The control command data 301 is data unique to the control command. The accompanying data 302 is data accompanying the control command data 301, and is control data necessary for executing processing corresponding to the control command data 301 such as data indicating the current gaming state, for example.

On the other hand, when transmitting the authentication data to the rear stage unit 20 via the effect control unit 203, the main control unit 10 adds individual authentication data in addition to the control command data 301 and accompanying data 302 as shown in FIG. 303 and control signal with authentication data 310 including operation authentication data 304, and control signal with personal authentication data 311 including individual authentication data 303 in addition to control command data 301 and accompanying data 302 as shown in FIG. As shown in FIG. 5 (4), an operation authentication data-added signal 312 including operation authentication data 304 in addition to the control command data 301 and accompanying data 302 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 signal 311 with individual authentication data and the control signal 312 with operation authentication data.

  The control signal with authentication data is not limited to the order shown in FIG. 5. For example, the individual authentication data 303 or the operation authentication data 304 is placed at the head of the control signal, or the individual authentication data between the control command data 301 and the accompanying data 302 is used. Data 303 or operation authentication data 304 may be inserted.

  Further, the individual authentication data 303 and the operation authentication data 304 are not added to the same control command data 301 and the accompanying data 302, but are added to different control command data 301 and the accompanying data 302, respectively. Also good. For example, in the control signal 311 with individual authentication data in FIG. 5 (3), only the individual authentication data 303 is added to the control command data 301 and the accompanying data 302. Further, in the control signal with operation authentication 312 in FIG. 5 (4), only the operation authentication data 304 is added to the control command data 301 and the accompanying data 302.

  The timing at which the main control unit 10 outputs the control signal with authentication data 310 (or the control signal with individual authentication data 311 and the control signal with operation authentication data 312, and so on) is arbitrary. For example, the control signal with authentication data 310 may be output every predetermined time, or the control signal with authentication data 310 may always be output. For example, when the control command data 301 in the control signal is a specific type of command, the control signal with authentication data 301 may be added.

  However, when the individual authentication data 303 and the operation authentication data 304 are transmitted separately (when the individual authentication data-added control signal 311 and the operation authentication data-added control signal 312 are transmitted), the individual authentication data 303 uses the operation authentication data 304. If it is generated, the operation authentication data 304 needs to be transmitted before authentication using the individual authentication data 303 is performed. Similarly, when the operation authentication data 304 is generated using the individual authentication data 303, it is necessary to transmit the individual authentication data 303 before the authentication using the operation authentication data 304 is performed.

  In this way, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, the main control unit 10 and the effect control are compared with the case where the individual authentication data 303 and the operation authentication data 304 are transmitted alone. An increase in communication load with the unit 203 can be suppressed. In addition, by including the individual authentication data 303 and the operation authentication data 304 in the control signal, the individual authentication data 303 and the operation authentication data 304 are compared with the case where the individual authentication data 303 and the operation authentication data 304 are transmitted alone. In addition, the risk that the operation authentication data 304 is extracted and analyzed can be reduced.

(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 obtained in this manner are stored in advance. Among the storage areas of the ROM 20b, the storage area in which the plurality of expected values are stored in advance can correspond to, for example, the calculated value storage means 21 shown in FIG. The RAM 20c functions as a work area for calculations performed when the CPU 20a executes intermediate processing.

In the first embodiment, this intermediate processing is as follows [1] to [7].
[1] Reception of control signal with authentication data The rear stage unit 20 receives a normal control signal 300 consisting of only the control command data 301 and the accompanying data 302 from the main control unit 10 via the effect control unit 203, or control command data. 301, control data with authentication data 310 composed of accompanying data 302, individual authentication data 303 and operation authentication data 304, control signal with individual authentication data 311 composed of control command data 301, accompanying data 302, and individual authentication data 303, or control An operation authentication data-added control signal 312 comprising command data 301, accompanying data 302, and operation authentication data 304 is received.

[2] Extraction of test value and synchronization code The post-stage unit 20 receives individual authentication data 303 and operation authentication data 304 from the control signal 310 with authentication data, and individual authentication data 303 and operation authentication data from the control signal 311 with individual authentication data. The operation authentication data 304 is extracted from the attached signal 312. Next, the post-stage unit 20 performs a decryption process corresponding to the encryption process used at the time of generating each authentication data on each extracted authentication data, and extracts a check value or a synchronization code. The rear stage unit 20 stores the extracted inspection value in a predetermined storage area of the RAM 20c (hereinafter referred to as inspection value memory).

[3] Individual authentication The post-stage unit 20 performs the semi-group operation on all the test values stored in the test value memory in the following order, so that the main control unit 10 performs normal main control. It is authenticated whether it is a part.
The {1} rear stage unit 20 performs a half group operation (hereinafter referred to as a combining process) using all the inspection values stored in the inspection value memory.
{2} The rear stage unit 20 reads an expected value stored in advance from a predetermined storage area of the ROM 20b.

The {3} latter-stage unit 20 determines whether or not the operation result in the process {1} (hereinafter referred to as a combination result) matches the expected value read in the process {2} (hereinafter referred to as a collation process). Called).
The post-stage unit 20 determines that the individual authentication is successful when the combination result and the expected value match.
Since the semi-group operation satisfies the above combination rule, an expected value that is a result obtained by performing the semi-group operation on all of the predetermined program codes stored in advance in the ROM 10b of the main control unit 10, This coincides with the combined result obtained by performing the semi-group operation on the inspection 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 been successful when the combined result and the expected value do not match.

If the authentication is successful in the processing of {4} {3}, the post-stage unit 20 generates an individual authentication result indicating that the individual authentication is successful.
{5} The post-stage unit 20 erases all the inspection values stored in the inspection value memory.

  Since the number of divisions is a value recognized only by the main control unit 10, even if the fraudster switches the half-group operation used for generating the test value, it cannot know the timing. Thereby, it can be detected that an unauthorized control unit is inserted between the main control unit 10 and the effect control unit 203, and unauthorized processing by the unauthorized control unit can be prevented.

If authentication is not successful in the processing of {6} {3}, the post-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.
{6-1} If the number of received authentication data is less than the predetermined number, the rear-stage unit 20 determines that the individual authentication is not yet possible, and instead of the individual authentication result, An arbitrary value (for example, all 0 or all 1) having the same data length as the data length of the individual authentication result is generated.
{6-2} 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 individual authentication has not been successful and generates an individual authentication result indicating that the individual authentication has not been successful. To do.

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

  The expected value used by the subsequent stage unit 20 for collation may be stored in advance in a predetermined storage area of the ROM 20b that configures the subsequent stage unit 20 at the time of manufacture, for example. It is good also as transmitting to 20. 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. Note that the expected value calculation unit may transmit the expected value stored in advance to the subsequent 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 that configures the rear stage unit 20 and acquired from another component unit, the inspection value can be changed afterwards. It becomes.

The post-stage unit 20 switches the expected value based on the number of combinations when the inspection value generation method in the main control unit 10 is switched. For example, when the number of divisions and the number of connections are odd, the inspection value generation method and the expected value are switched. When the number of divisions and the number of connections is an even number, the previously used inspection value generation method and the expected value are continued. use. 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 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 test value generation method. Thereby, it is possible to prevent the inspection value from being illegally generated by an unauthorized person.
[4] Operation authentication

  The post-stage unit 20 authenticates the operation sequence of the main control unit 10 using the operation authentication data 304. As described above, the operation authentication data 304 includes a plurality of pieces of packet information generated at successive timings. Therefore, it is possible to determine whether or not the packet information has a predetermined correlation by obtaining the difference between the plurality of pieces of packet information. When the predetermined correlation is maintained, the control command transmission process has continuity, and is not a control command transmitted from another unauthorized control board, so that the correct operation order is authenticated.

  Specifically, the synchronization state is verified from the correlation between the two pieces of packet information output at successive timings. For example, the basic value of the first packet (hereinafter referred to as “packet 1”) = 0x03, the basic value of the second packet (hereinafter referred to as “packet 2”) = 0x05, and the correlation condition between packet 1 and packet 2 (Authentication establishment condition) is “+2”. The inspection value of packet 1 transmitted from the main control unit 10 remains 0x03 as the basic value, and the inspection value of packet 2 becomes packet 1 + packet 2, that is, 0x03 + 0x05, and “0x08” is transmitted.

  Then, the packet 1 received by the rear stage unit 20 is 0x03 as the basic value, and the packet 2 is 0x08. Then, in order to calculate the basic value of the packet 2, the packet 1 is subtracted from the received packet 2 to obtain 0x08-0x03 = 0x05.

  When the basic values of both packet 1 and packet 2 are obtained, the correlation between the two packets is obtained. That is, packet 2 basic value−packet 1 basic value = 0x05−0x03, and the correlation value is 0x02. Since this value satisfies the correlation condition (which is +2) between the basic value of packet 1 and the basic value of packet 2, it is determined that authentication is established.

  In arithmetic processing using packet 1 and packet 2, the number of digits may be adjusted so that the arithmetic result does not overflow, or the basic values of packet 1 and packet 2 are selected within a numerical range that does not overflow. Alternatively, it may be calculated as an unsigned operation. Further, the correlation condition may be changed for each authentication process in order to increase the authentication strength. For example, the first correlation condition may be “+2”, the second correlation condition may be “+5”, the third correlation condition may be “+1”, and the like. However, when the correlation change rule as described above is applied, the main control unit 10 and the subsequent stage unit 20 share in advance or prepare means and processes for notification.

  In addition, simply transmitting continuous packet information may cause a third party to analyze packet information differences. Accordingly, the basic value may be preprocessed to prevent analysis. For example, various arithmetic processing such as exclusive OR operation may be performed on the basic value of the packet information. In addition, the preprocessing to the basic value may be performed only on one of the two pieces of packet information output at an output timing set in advance at an arbitrary interval such as packet 1 and packet 2. , May be applied to both.

  The post-stage unit 20 switches the synchronization code authentication method when the coupling number is an odd number, and continues the packet information without switching when the number is an even number.

  If the operation authentication data 304 has been subjected to a predetermined operation, the subsequent stage unit 20 performs the predetermined operation according to the content of the operation processing of the main control unit 10 and obtains a synchronization code. When the synchronization code is a code representing the continuation state of the operation of the main control unit 10, it is authenticated that the operation of the main control board 310 is in the correct order. In addition, when receiving the direct synchronization code, the rear stage unit 20 authenticates the operation sequence of the main control unit 10 using the synchronization code.

  In the above description, the individual authentication data 303 and the operation authentication data 304 are independently authenticated, but the operation authentication data 304 is generated using a part of the individual authentication data 303. If the individual authentication data 303 is generated using a part of the operation authentication data 304, the authentication with one of the authentication data is completed and then the authentication with the other authentication data is performed. .

[5] Generation of Authentication Unsuccessful Signal When the authentication result generated in the process of [3] is a result indicating that the authentication has not been successful, the latter stage unit 20 authenticates based on the result of the authentication failure. Generate a failure signal. 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 authentication data.

[6] Transmission of Authentication Unsuccessful Signal The subsequent stage unit 20 transmits an authentication unsuccessful signal to the effect control unit 203.
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.

  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. The processing related to authentication shown in [1] to [4] is executed.

[1] Reception of Control Signal The effect control unit 203 determines whether the control signal transmitted from the main control unit 10 is a normal control signal including only the control command data 301 and the accompanying data 302, or the control command data 301 and the accompanying data 302. It is determined whether the control signal has authentication data 303 to which authentication data 303 is added.
[2] Execution of processing based on control command 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.
[3] Transmission of control signal with authentication data to subsequent stage 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 stage. 20 is transmitted as it is. Note that the authentication data 303 may be extracted from the control signal with authentication data, and only the authentication data may be transmitted to the subsequent stage unit 20. Further, the effect control unit 203 may transmit it directly to the subsequent stage unit 20 regardless of the type of the received control signal.
[4] 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 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 power to the pachinko gaming machine 1 is turned on, the peripheral board stands up and performs initialization of the RAM area in order to reliably capture the control command received from the main control board. After entering the state, 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 the effect control unit 203, the prize ball control unit 204, and the effect. Control command to be transmitted to the post-stage unit 20 and the lamp control unit 205 via the control unit 203, and initial control information for controlling the game at the start-up after power-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. If the determination result in step S20 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 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 | presentation control part 203 will progress to step S44.

  In step S44, the effect control unit 203 transmits to the symbol display unit 104 or the lamp control unit 205 a round-by-round processing command corresponding to the received round-by-round jackpot command, and then proceeds to step S45. In step S45, it is determined whether 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, game media such as medals and game balls are paid out regardless of games due to illegal acts performed on gaming machines or malfunctions of gaming machines due to noise, etc. You may suffer damage. 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, when the output control command is a predetermined control command, the main control unit 10 generates individual authentication data and operation authentication data for the number of divisions using a predetermined program code. Then, each of these authentication data is added to a predetermined control command and transmitted to the rear stage unit 20 via the effect control unit 203.

  The post-stage unit 20 uses the inspection value obtained from each authentication data received from the main control unit 10 via the effect control unit 203 and the synchronization code to determine whether the main control unit 10 is a regular main control unit. Authenticate. Next, the post-stage unit 20 transmits an authentication unsuccessful signal to the effect control unit 203 when the authentication result obtained by the authentication process is unsuccessful. 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 and 13, but authentication between the main control unit 10 and the prize ball control unit 204 is performed. The processing related to 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 determines whether it is the transmission timing of the authentication data while transmitting a normal control signal (step S61) (step S62). If the determination result is NO, the main control unit 10 returns to step S61 and performs the determination in step S62 again. When the authentication data transmission timing comes, the determination result in step S62 is “YES”, and the main control unit 10 proceeds to step S63 to determine the number of divisions. The method for determining the number of divisions is arbitrary. The number of divisions may be determined before the transmission timing of authentication data.

Next, the main control unit 10 divides a predetermined program code by the determined number of divisions, performs a semi-group operation on each, calculates a test value (step S64), and encrypts the test value To generate individual authentication data (step S65). By this process, test values and individual authentication data for the number of divisions are generated. In addition, the test value generation method (such as the type of calculation used for generation) is determined at the time of the previous individual authentication data transmission.
Subsequently, the main control unit 10 acquires a synchronization code from the packet information output with the transmission of the control command (step S66), and performs a predetermined calculation on the synchronization code to generate operation authentication data. (Step S67).

  Next, the main control unit 10 sequentially transmits a control signal with authentication data including the generated individual authentication data and operation authentication data (step S68). The control signal with authentication data may be transmitted continuously, or may be mixed with a normal control signal and transmitted. The order of transmitting the authentication data is also arbitrary. The main control unit 10 returns to step S68 and continues to transmit the control signal with authentication data until all the authentication data generated in step S65 and step S67 are transmitted (step S69: NO).

  When all the authentication data is transmitted (step S69: YES), it is determined whether or not the number of divisions determined in step S63 is a predetermined value (step S70). The predetermined value is, for example, an odd number (or even number). When the number of divisions is a predetermined value (step S70: YES), the main control unit 10 switches the type of packet information used for acquisition of the synchronization code (step S71), and ends the process according to this flowchart. On the other hand, if the number of divisions is not a predetermined value (step S70: NO), the processing according to this flowchart is terminated without switching the type of packet information used for acquisition of the synchronization code.

  The main control unit 10 may add the authentication data 303 to the control command only when transmitting a predetermined control command to the subsequent stage unit 20. In this case, since the authentication process is performed only when a predetermined control command is transmitted, the rate at which the processing load on 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 each authentication data is extracted from the control signal can be reduced. Moreover, even if each authentication data is extracted from the control signal, since the number of samples that can be acquired is small, the risk that each authentication data is analyzed can be reduced.

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

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

  When the predetermined control command is a customer waiting demo command or a customer waiting demo stop command, the customer waiting demo command or the customer waiting demo stop command indicates that the pachinko gaming machine 1 is in a non-game state, that is, the main of the pachinko gaming machine 1 This is transmitted when the game (game progress) related process is not performed, so that an increase in processing load due to the authentication process does not affect the game related process. For this reason, even 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” is the most frequently generated lottery result at the time of lottery, so that each authentication data 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.

  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 post-stage unit 20 determines whether or not a control signal with authentication data as shown in FIG. 5 transmitted from the main control unit 10 via the effect control unit 203 has been received (step S81). When the determination result is “NO”, the rear stage unit 20 repeats the same determination. And if the control signal with authentication data is received from the main control unit 10 via the effect control unit 203 (step S81: YES), the rear stage unit 20 proceeds to step S82.

  When receiving the control signal with authentication data (step S81: YES), the subsequent stage unit 20 extracts the individual authentication data and the operation authentication data from the control signal, and further performs a decoding process to obtain the inspection value and the synchronization code. (Step S82). The subsequent stage unit 20 stores the acquired inspection value in the inspection value memory and the synchronization code in the synchronization code memory (step S83), and performs a semi-group operation (join processing) on all the inspection values in the inspection value memory. (Step S84). Note that the type of half-group operation performed in step S84 is determined when the previous authentication data is received. If there is one inspection value in the inspection value memory, the process directly proceeds to step S85 without performing the combining process.

  Then, the rear stage unit 20 compares the operation result (combination result) with the expected value of the stored test value, and determines whether or not the combination result and the expected value match (step S85). If the combined result matches the expected value (step 85: YES), the rear stage unit 20 makes the individual authentication to the main control unit 10 successful (step S86), and proceeds to step S87.

Further, the rear stage unit 20 checks whether packet information included in the acquired synchronization code satisfies a predetermined correlation. If the predetermined correlation is satisfied (step S88: YES), the subsequent stage unit 20 succeeds in the operation authentication for the main control unit 10 (step S89).
Here, the correlation between packet information is, for example, a difference or an arbitrary interval.

  Subsequently, the post-stage unit 20 determines whether or not the number of test values (joining number) subjected to the joining process when the individual authentication is successful is a predetermined value (step S90). The predetermined value is, for example, an odd number (or even number). When the number of combinations is a predetermined value (step S90: YES), the post-stage unit 20 switches the packet information included in the synchronization code used for authentication (step S91), and deletes the test value memory and the synchronization code memory data. (Step S92).

  In step S85, if the test value calculation result does not match the expected value (step S85: NO), the rear stage unit 20 receives a predetermined number or more of individual authentication data (step S93: NO), step S81. Return to and repeat the join process. When the individual authentication data of a predetermined number or more is received (step S93: YES), the rear stage unit 20 makes the authentication to the main control unit 10 unsuccessful (step S94), and proceeds to step S95. 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. Similarly, when the difference between the packet information does not satisfy the predetermined correlation (step S88: NO), the rear stage unit 20 makes the authentication with respect to the main control unit 10 unsuccessful (step S94), and proceeds to step S95.

  In step S82, when each authentication data is not included in the control signal, that is, when the control signal is the normal control signal 300 (step S82: NO), the rear stage unit 20 does not perform the authentication process. The received normal control signal 300 is transmitted as it is to the effect control unit 203 (step S98), and the processing according to this flowchart ends.

  In this way, the post-stage unit 20 does not generate and transmit the authentication success signal when the authentication of the main control unit 10 is successful, and transmits the authentication unsuccessful signal only when the authentication is unsuccessful. The rate at which the processing load of 20 increases due to the authentication process can be suppressed.

  In addition, since each authentication process such as decryption of each authentication data, collation between the inspection value and the expected value, and whether the packet information satisfies a predetermined correlation is executed only by the rear-stage unit 20, the effect control unit 203 is configured. The processing load on the CPU 203a 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. 14 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 the control signal transmitted from the main control unit 10 has been received (step S101). The effect control unit 203 repeats the same determination when the control signal transmitted from the main control unit 10 is not received (step S101: NO). And if the control signal transmitted from the main control part 10 is received (step S101: YES), the production | presentation control part 203 will progress to step S102.

  In step S102, the effect control unit 203 determines whether authentication data is included in the received control signal. In the case of the normal control signal 300 in which the authentication data is not included in the received control signal (step 102: NO), the effect control unit 203 is based on the control command data 301 and the accompanying data 302 included in the normal control signal 300. Processing is performed (step S107), and the processing according to this flowchart is terminated.

  On the other hand, when the authentication data is included in the control signal received by the effect control unit 203 (step S102: YES), the effect control unit 203 proceeds to step S103. Here, the determination of whether or not the authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, or whether the control command data 301 or accompanying data is included in the control signal. This is performed by determining whether or not any bit constituting 302 or identification data (not shown) provided separately indicates that it is included in the authentication data. In the process of step S102, the effect control unit 203 does not determine whether or not the authentication data 303 is included in the received control signal, but the control command data 301 included in the control signal performs the authentication process. It may be determined whether or not the control command data is a predetermined control command set in advance for execution.

  In step S103, the effect control unit 203 transmits the received control signal with authentication data to the subsequent unit 20 as it is, and then starts processing based on the control command data 301 and the accompanying data 302 (step 104), and then proceeds to step S105. move on.

  In step S <b> 105, the effect control unit 203 determines whether an 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 S105: 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 processing according to this flowchart. Exit.

  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.

  Further, in the flowchart of FIG. 14, the effect control unit 203 determines whether the control signal transmitted from the main control unit 10 is a normal control signal or a control signal with authentication data. Instead, it may be transmitted to the subsequent stage 20 as it is regardless of the type of the received control signal. Specifically, the effect control unit 203 does not determine whether or not the authentication data 303 is included in the received control signal, and transmits it to the subsequent stage unit 20 as it is, and also transmits it to the control command data 301 and the accompanying data 302. Start processing based on. In this case, the post-stage unit 20 determines whether or not the authentication data 303 is included in the received control signal. If the authentication data 303 is included, the post-processing unit 20 starts the combining process. Without starting the process, the received control command data 301 and the accompanying data 302 are discarded, and the process relating to the authentication of the subsequent stage unit 20 is terminated.

  Next, a specific example of the packet information type switching process among the processes shown in FIGS. 12 and 13 will be described. FIG. 15 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the succeeding unit 20 (authenticated person). In FIG. 15, there are two types of packet information, and when the number of divisions is an odd number, the type of packet information (continuous packet information and intermittent packet information) used to generate a synchronization code is switched. In addition, packet information used as default is continuous packet information. 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 proceeds to the process of step S111, determines the number of divisions used for the current authentication process by an arbitrary method, and then proceeds to step S112. For example, the main control unit 10 determines that the current number of divisions is three. In step S112, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into three blocks (storage areas), and uses the program code stored in each block, After obtaining the inspection value, the process proceeds to step S113.

In step S113, the main control unit 10 performs the encryption process on the inspection value to generate individual authentication data, and then proceeds to step S114. In step S114,
After acquiring the synchronization code from the continuous packet information, the main control unit 10 proceeds to step S115. In step S115, operation authentication data is acquired by performing encryption processing on the synchronization code, and then the process proceeds to step S116. In step S116, the main controller 10
Transmits the control signal with authentication data including the individual authentication data and the synchronization code to the rear stage unit 20 via the effect control unit 203, and then proceeds to step S117.

  In step S117, the main control unit 10 switches the type of packet information used for acquiring the synchronization code because the current division number is an odd number. Specifically, the packet information used for generating the synchronization code is switched from continuous packet information to intermittent packet information.

  As a result, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S118), and then proceeds to step S119. In step S119, the post-stage unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and then proceeds to step S120. In step S120, the post-stage unit 20 performs a decryption process on the individual authentication data and the operation authentication data, thereby obtaining the inspection value and the synchronization code, and storing them in the inspection value memory and the synchronization code memory. The process proceeds to step S121.

In step S121, the post-stage unit 20 performs a combining process on the acquired inspection value, and then proceeds to step S122. In step S122, the post-stage unit 20 collates the combined result with the expected value, determines that the authentication is successful when the combined result and the expected value match, and determines that the combined result does not match the expected value. After determining that the authentication is not successful, the process proceeds to step S123.
In this case, when the joining process is performed using three inspection values, the joining result and the expected value should match (joining number = 3).

  In step 123, the post-stage unit 20 collates whether or not the packet information included in the synchronization code satisfies the correlation corresponding to the continuous packet information. If the difference between the packet information satisfies the correlation corresponding to the continuous packet information, the latter stage unit 20 proceeds to step S124 after successfully authenticating the operation order of the main control unit 10. In step S124, the latter stage unit 20 switches the synchronization code authentication method (correlation between differences in packet information) because the current number of connections is an odd number. Specifically, the correlation corresponding to the continuous packet information is switched to the correlation corresponding to the intermittent packet information. This is the flow of a series of switching processes.

  Turning to the description of the second authentication process, the main control unit 10 proceeds to the process of step S125, determines again the number of divisions used for the current authentication process by an arbitrary method, and then proceeds to step S126. For example, the main control unit 10 determines that the current number of divisions is four. In step S126, the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into four blocks (storage areas), and uses the program code stored in each block, After obtaining the inspection value, the process proceeds to step S127.

  In step S127, the main control unit 10 performs the encryption process on the inspection value to generate authentication data, and then proceeds to step S128. In step S128, the main control unit 10 acquires the synchronization code and then proceeds to step S129. In step S129, after the operation authentication data is obtained by performing encryption processing on the synchronization code, the process proceeds to step S130. In step S130, the main control unit 10 transmits a control signal with authentication data including individual authentication data operation authentication data to the subsequent stage unit 20 via the effect control unit 203, and then proceeds to step S131. In step S131, since the current number of divisions is an even number, the main control unit 10 continues the intermittent packet information without switching the type of packet information used for acquisition of the synchronization code.

  As a result, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S132), and then proceeds to step S133. In step S133, the post-stage unit 20 extracts the individual authentication data and the operation authentication data from the control signal with authentication data, and then proceeds to step S134. In step S134, the post-stage unit 20 performs a decryption process on the authentication data, thereby obtaining the check value and the synchronization code, storing them in the check value memory and the synchronization code memory, and then proceeds to step S135. .

In step S135, the post-stage unit 20 performs a combining process on the acquired inspection value, and then proceeds to step S136. In step S136, the post-stage unit 20 compares the combined result with the expected value, determines that the authentication is successful when the combined result and the expected value match, and determines that the combined result does not match the expected value. After determining that the authentication is not successful, the process proceeds to step S137.
In step 137, the post-stage unit 20 extracts the synchronization code from the control signal with authentication data, collates whether or not the difference between the packet information satisfies the correlation corresponding to the intermittent packet information, and then proceeds to step S138. . In step S137, when the difference between the packet information satisfies the correlation corresponding to the continuous packet information, the latter stage unit 20 succeeds in the authentication with respect to the operation order of the main control unit 10, and then proceeds to step S138. . In step S138, since the number of couplings this time is an even number, the post-stage unit 20 continues without changing the synchronization code authentication method (correlation between differences in packet information).

  In this case, the main control unit 10 divides a predetermined program code stored in the ROM 10b, and sets the generation method (data packet type and encryption method) of authentication data at the next authentication based on the number of divisions. change. Since the number of divisions is a value that only the main control unit 10 knows, the fraudster cannot know the switching timing of the half-group operation used for generating the authentication data value. For this reason, it is possible to detect the cheating and the malfunction of the gaming machine.

  Note that the post-stage unit 20 may perform the authentication process using the authentication data not when the authentication data is received but when the plurality of authentication data is received. In this case, for example, when receiving the first authentication data together with the first control command data and the first associated data of the predetermined control command, the rear stage unit 20 performs the predetermined control command without performing the authentication process. Processing based on the first control command data and the first accompanying data is performed. When the second authentication data is received together with the second control command data of the predetermined control command and the second accompanying data, the rear stage unit 20 receives the second control command data of the predetermined control command and the second control command data. Before performing the process based on the accompanying data, an authentication process using the first authentication data is performed. At this time, the rear stage unit 20 may perform the authentication process using both the first authentication data and the second authentication data.

  Further, the authentication data 303 may be generated including the control command data 301 and the accompanying data 302 transmitted this time. As a result, it is possible to prevent unauthorized use and malfunction by detecting reuse of each authentication data by an unauthorized main control unit, and to prevent unauthorized control commands from being executed due to unauthorized actions or malfunctions. be able to.

Further, the post-stage unit 20 generates an authentication unsuccessful signal only when the authentication is unsuccessful and transmits it to the effect control unit 203, but also generates and transmits an authentication success signal to the effect control unit 203 when the authentication is successful. May be.
Further, the rear stage unit 20 transmits only the authentication unsuccessful signal to the exercise control unit 203, and the presentation control unit 203 interrupts the processing based on the control command when the authentication unsuccessful signal is received. Not. For example, the post-stage unit 20 also transmits an authentication success signal to the effect control unit 203, and the effect control unit 203 suspends processing based on the control command and receives an authentication success signal until an authentication success signal is received from the post-stage unit 20. Then, processing based on the control command may be executed. Thereby, it can prevent that the production | presentation control part 203 performs the unauthorized control command resulting from an unauthorized act or malfunction.

In the pachinko gaming machine 1 according to the first embodiment, authentication data for authenticating the legitimacy of the main control unit 10 is generated at a timing when a predetermined control command is transmitted, and authentication processing is performed using the generated authentication data. I do. The processing load on the main control unit 10 and the effect control unit 203 increases only during a period during which a predetermined control command is transmitted, and the processing load on the main control unit 10 and the effect control unit 203 increases. Can increase the rate of increase.

Further, 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 of each other, the authentication program and the effect program can be designed separately. 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 changing the authentication algorithm for authentication, the process in the peripheral part 30 which performs a predetermined process 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.

  In addition, since each authentication data 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.

  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 authentication data 303 obtained by performing a complicated or advanced encryption process to each inspection value to the subsequent stage unit 20, and the subsequent stage unit 20 receives the above-mentioned An authentication success signal or an authentication failure signal (obtained by applying a relatively simple or low-level encryption process to the authentication result obtained by authenticating the main control unit 10 using each inspection value obtained from the authentication data 303 ( Hereinafter, the 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 a margin in comparison, the main control unit 10 transmits the respective inspection values as the authentication data 303 as they are or transmits the authentication data 303 obtained by performing relatively simple or low-level encryption processing to the subsequent stage unit 20. The succeeding unit 20 is an authentication success signal obtained by subjecting the authentication result obtained by authenticating the main control unit 10 using each inspection value obtained from the received authentication data 303 to a complicated or advanced re-encryption process. And the like are 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 a 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 (such as version upgrade), the data structure of each inspection value, etc. The same applies to the case where a formal difference occurs between the main control unit 10 and the effect control unit 203.

<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 the target of test value generation. 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 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 semi-group operation for each data block, and generates 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 inspection 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 test value until the generation of the 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 inspection values are generated (that is, how many divisions are to be made) depends on the generation of inspection values using all program codes in a predetermined area of the ROM 10b. I do not know until completion.

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

(Specific example of test value generation)
An example in which the test value is generated by the method A using addition as the semi-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 for generating the first inspection value is determined to be 4 bytes, 4 bytes of program code (“0x01”, “0x02”, “0x03”, “0x04”) are divided into first blocks 400a. Next, the program code “0x01”, “0x02”, “0x03”, “0x04” stored in the first block 400a is added to obtain the first inspection value “0x0A”.

  Subsequently, when it is determined that the data amount used for generating the second inspection value is 3 bytes, the program code stored in the program code storage area 400 excluding the program code stored in the first block 400a A 3-byte program code (“0x05”, “0x06”, “0x07”) is divided from the code to form a second block 400b. Next, the program code “0x05”, “0x06”, “0x07” stored in the second block 400b is added to obtain the second inspection value “0x12”.

  Subsequently, when it is determined that the amount of data used for generating the third inspection value is 7 bytes, among the program codes stored in the program code storage area 400, the programs stored in the first block 400a and the second block 400b Since the program code excluding the 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 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 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 test value.

  Hereinafter, a process related to authentication in the main control unit will be described. FIG. 16 is a flowchart illustrating an example of processing related to authentication by the main control unit. In this flowchart, a process when the data amount is determined every time a test value is generated and a predetermined program code is divided will be described. The main control unit 10 waits until the authentication data transmission timing comes (step S142: NO) while transmitting a normal control signal (step S141). When the transmission timing of the authentication data comes (step S142: YES), the main control unit 10 determines the data amount of the program code used for generating the inspection value (step S143). The method for determining the data amount is arbitrary.

Next, the main control unit 10 divides a predetermined program code by the determined number of divisions, performs a semi-group operation on each, calculates a test value (step S144), and encrypts the test value To generate individual authentication data (step S145). By this process, test values and individual authentication data for the number of divisions are generated. In addition, the test value generation method (such as the type of calculation used for generation) is determined at the time of the previous individual authentication data transmission.
Subsequently, the main control unit 10 acquires a synchronization code from the packet information output with the transmission of the control command (step S146), and performs a predetermined calculation on the synchronization code to generate operation authentication data. (Step S147).

  Next, the main control unit 10 sequentially transmits a control signal with authentication data including the generated individual authentication data and operation authentication data (step S148). The control signal with authentication data may be transmitted continuously, or may be mixed with a normal control signal and transmitted. The order of transmitting the authentication data is also arbitrary. The main control unit 10 returns to step S148 and continues to transmit the control signal with authentication data until all the authentication data generated in step S145 and step S147 is transmitted (step S149: NO).

  When all the authentication data is transmitted (step S149: YES), it is determined whether or not the number of divisions determined in step S143 is a predetermined value (step S150). The predetermined value is, for example, an odd number (or even number). When the number of divisions is a predetermined value (step S150: YES), the main control unit 10 switches the type of packet information used for acquisition of the synchronization code (step S151), and ends the processing according to this flowchart. On the other hand, if the number of divisions is not a predetermined value (step S150: NO), the processing according to this flowchart is terminated without switching the type of packet information included in the synchronization code.

  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. The post-stage unit 20 extracts authentication data from the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203, performs authentication processing using the authentication data, and performs authentication processing when authentication is unsuccessful. A success signal is generated and 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.

(Specific example of packet information type switching processing)
Next, a specific example of packet information type switching processing 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 packet information, and when the number of divisions is an odd number, the type of packet information (continuous packet information and intermittent packet information) used to generate a synchronization code is switched. In addition, packet information used as default is continuous packet information. In this sequence diagram, for convenience of explanation, the data amount used to generate the inspection value is collectively determined. However, as shown in the flowchart of FIG. 17, the data amount is determined every time the inspection value is generated. May be.

First, the main control unit 10 determines a data amount used for generating authentication data by an arbitrary method. For example, if the total amount of data is 12 bytes, and the amount of data used to generate inspection values is 4 bytes, 3 bytes, and 5 bytes, respectively, three inspection values are generated, and the number of divisions = 3 ( Step S161).
The main control unit 10 reads out 4-byte, 3-byte, and 5-byte program codes in order from the top of the program code storage area 400, and calculates a test value using each program code (step S162). The main control unit 10 performs encryption processing on the test value to generate individual authentication data (step S163). Further, a synchronization code is acquired (step S164), and the synchronization code is subjected to encryption processing to generate operation authentication data (step S165). Then, the control signal with authentication data including the authentication data is transmitted to the rear stage unit 20 via the effect control unit 203 (step S166).

  Thereafter, the main control unit 10 switches the type of packet information used for acquiring the synchronization code because the current division number is an odd number. Specifically, the packet information used for generating the synchronization code is switched from continuous packet information to intermittent packet information (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 via the effect control unit 203 (step S168). Then, individual authentication data is extracted from the control signal with authentication data (step S169), and a decryption process is performed to obtain a test value (step S170). The subsequent stage unit 20 performs a combination process on the acquired inspection value (step S171), and collates the combination result with the expected value. If it matches the expected value, the rear stage unit 20 makes the authentication with the main control unit 10 successful (step S172). In this case, when combining processing is performed using three inspection values, it should match the expected value (number of connections = 3).

  Then, the operation authentication data is extracted (step S173), and when the operation authentication data satisfies the correlation in which the difference between the packet information corresponds to the continuous packet information, the succeeding stage unit 20 succeeds in the authentication of the operation order of the main control unit 10 (Step S174).

  Thereafter, the subsequent stage unit 20 switches the synchronization code authentication method (correlation between differences in packet information) because the current number of connections is an odd number. Specifically, the correlation corresponding to the continuous packet information is switched to the correlation corresponding to the intermittent packet information (step S175).

Turning to the description of the second authentication process, the main control unit 10 again determines the amount of data used for generating authentication data by an arbitrary method. For example, if the amount of data used to generate the inspection value is 4 bytes, 2 bytes, 3 bytes, and 3 bytes, respectively, four inspection values are generated, and the number of divisions is 4 (step S176). The main control unit 10 reads out the 4-byte, 2-byte, 3-byte, and 3-byte program codes in order from the top of the program code storage area 400, and calculates the inspection value using each program code (step S177).
The main control unit 10 performs an encryption process on the inspection value to generate individual authentication data (step S178). Further, a synchronization code is acquired (step S179), and an encryption process is performed on the synchronization code to generate operation authentication data (step S180). Then, a control signal with authentication data including authentication data is transmitted to the rear stage unit 20 via the effect control unit 203 (step S181).

  Thereafter, since the current division number is an even number, the main control unit 10 continues the intermittent packet information without switching the type of packet information used for acquisition of the synchronization code (step S182).

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 via the effect control unit (step S183). Then, individual authentication data is extracted from the control signal with authentication data (step S184), and a decryption process is performed to obtain a test value (step S185). The post-stage unit 20 performs a combination process on the acquired inspection value (step S186), and collates the combination result with the expected value. If it matches the expected value, the rear stage unit 20 makes the authentication with the main control unit 10 successful (step S187). In this case, when the joining process is performed using four inspection values, it should match the expected value (number of joins = 4).
Then, the operation authentication data is extracted (step S188), and when the operation authentication data satisfies the correlation in which the difference between the packet information corresponds to the continuous packet information, the succeeding stage unit 20 succeeds in the authentication of the operation order of the main control unit 10 (Step S189).

  Thereafter, the subsequent stage unit 20 continues with the intermittent packet information without switching the type of packet information used for acquisition of the synchronization code because the current combination number is an even number (step S190).

  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 the 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 respective 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. You don't have to.

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.
