(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. An authentication means for determining and authenticating the encrypted data if it is valid, an operation control means for causing the symbol display device to perform an operation corresponding to the encrypted data when the received encrypted data is authenticated, and a first key Second key change means for changing the second key data so as to correspond to the first key data at a predetermined timing so as to coincide with the data change timing (see, for example, Patent Document 2). ). Hereinafter, this technique is referred to as a second conventional example.

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

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

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

  As described above, in order to cause the CPU to execute the authentication process in addition to the existing process (for example, the effect process), it is necessary to add processes such as an authentication function and an authentication timing to the existing process. For this reason, a great deal of time and effort is spent on the design of the authentication timing for adding the authentication function, the realization of the authentication function, the simulation of the operation, and the verification (verification) to confirm whether the desired function can be obtained. Therefore, there is a problem that it takes a lot of time and effort to develop a gaming machine. Such a problem particularly appears when changing the model of a gaming machine. Furthermore, with the recent diversification of the effects of gaming machines, the code size of programs to be executed by the CPU tends to become enormous, so that the above problem increases with the addition of the authentication function.

  In addition, when the CPU performs authentication processing in addition to the existing processing, the processing load of the CPU increases, so the processing speed decreases, display for production is not performed smoothly, or in the worst case There was a problem that the authentication process itself could not be added. In particular, in recent years, in order to improve the interest of the game, there is a tendency that the effects of appealing to the visual and auditory senses of the player at the time of reach, jackpot, etc. tend to be diverse, and the possibility that the above problem will occur increases.

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

  On the other hand, in the second conventional example, in the main control unit, the encryption unit performs encryption corresponding to the first key data on the control data for controlling the operation of the symbol control unit, and the first key change unit The first key data is changed at a predetermined timing. In the peripheral unit, the authenticating unit performs processing corresponding to the second key data on the encrypted data received from the main control unit, thereby determining the validity of the received encrypted data. Authentication is performed, and the second key data is changed to correspond to the first key data at a predetermined timing so that the second key changing means matches the change timing of the first key data. That is, the main control unit and the peripheral unit perform sophisticated and complicated encryption processing and authentication processing. Therefore, in the second conventional example, since the processing load of both the CPU constituting the main control unit and the CPU constituting the peripheral part increases, the processing speed decreases, and the basic process and the effect process accompanying the progress of the game content. The original process may not be performed smoothly.

  Further, in the third conventional example, as in the first conventional example, when the peripheral CPU executes an authentication process in addition to the existing game process, authentication data is added to a predetermined control command and the peripheral process is performed. Even if it is transmitted to the part, the processing load on the CPU in the peripheral part increases, so the processing speed decreases, the display for presentation is not performed smoothly, or it is difficult to add the authentication process itself It is conceivable that there will be restrictions. In recent years, in particular, in order to improve the interest of the game, there is a tendency for various effects to appeal to the visual and auditory sense of the player regarding the control of the variation of the pattern. Therefore, it is desirable to construct a gaming machine provided with an authentication unit that reduces the load of performing an authentication process on a peripheral part (image control part) that performs various effects control.

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

  By the way, a gaming machine may malfunction when external electrical noise or mechanical vibration is applied. For example, when a control command is transmitted from the main control unit to the peripheral part, if noise such as electromagnetic waves or static electricity is added from the outside of the gaming machine, a bit error occurs in the control command data due to the influence of the noise, and control is performed. A malfunction occurs that the command is changed. In this case, if a bit error occurs and the control command is changed to a jackpot command even though the control command that should be transmitted to the peripheral part is a control command other than the jackpot command, an illegal action is performed. Even if this is not the case, an unreasonable amount of game media is paid out to the player, and the game store suffers a great deal of damage. However, in the first to third conventional examples, no countermeasures are taken for the problem caused by such a malfunction, so that the problem that the game shop suffers a great deal of damage cannot be solved.

  The present invention has been made in view of the above circumstances, and can detect fraudulent acts and malfunctions of gaming machines due to replacement of a regular main control board and an unauthorized main control board of a gaming machine. It is an object of the present invention to provide a gaming machine, a main control unit, a main control board, an intermediate part, a peripheral board, an authentication method, and an authentication program that can reduce the processing load.

The type of the specific control command to which the plurality of inspection values generated by the inspection value generation unit used when the authentication of the main control unit is performed next time is added When the authentication is successful And selecting based on the number of first time the test values be learned by the intermediate portion when said a number of test values were subject to binary operation authentication is successful.

Furthermore, in order to solve the above-described problems, the present invention is an intermediate unit provided in a gaming machine having a main control unit and a peripheral unit, and uses predetermined data stored in the main control unit. The calculation value storage means storing the calculation values obtained by performing one or a plurality of binary operations satisfying the combination rule and the data obtained by dividing the predetermined data by the main control unit When a plurality of test values generated by performing one binary operation among one or a plurality of binary operations satisfying the law are added to a specific control command selected in advance, the plurality of inspection values are transmitted. The binary calculation is performed using the inspection value, and the calculation result and the calculation value corresponding to the binary calculation stored in the calculation value storage means match the main value. and a certification means that authenticates the control unit, the authentication unit The authentication result obtained by adding a predetermined control command is transmitted to the peripheral portion, the authentication unit, the plurality of test generated by the main control unit used to authenticate the next time the main control unit The type of the specific control command to which a value is added is the number of the inspection values that are the targets of the binary operation when the authentication is successful, and the intermediate unit is the first time when the authentication is successful. The selection is made based on the number of inspection values to be obtained.

  Furthermore, in order to solve the above problems, the peripheral board of the gaming machine of the present invention is characterized in that the intermediate portion of the present invention and the peripheral portion are mounted.

Furthermore, in order to solve the above-described problem, the present invention provides an authentication method used in a gaming machine including a main control unit, an intermediate unit, and a peripheral unit, wherein a control command output by the main control unit is predetermined. The main control unit divides predetermined data stored in the data storage means, and uses one of the divided data to satisfy a combining law. one performs binary operation of generating a plurality of test values, a first step that sends to the intermediate portion in addition to preselected specific control command to said plurality of test values, the The type of the specific control command to which a plurality of inspection values generated by the main control unit used when the main control unit performs the next authentication of the main control unit is added, and the divided data The second step to select based on the number of And flop, said intermediate portion, performs the same dyadic operation as the main controller using been said plurality of test values transmitted from the main control unit, and the calculation result is stored in the data storage means Based on whether or not the calculated values corresponding to the two-term operation among the calculated values obtained by performing the one or plural binary operations using the predetermined data match, the main control unit a third step you authenticating, the intermediate portion, the specific control command in which the plurality of test values generated are added by the main control unit used to authenticate the next time the main control unit Is the number of the inspection values that are the targets of the binary operation when the authentication is successful, and the number of the inspection values that can be known for the first time when the authentication is successful. A fourth step of selecting based on the intermediate portion, The authentication result obtained by the serial third step by adding a predetermined control command; and a fifth step of transmitting to the peripheral portion.

Furthermore, in order to solve the above-described problem, a computer-readable authentication program according to the present invention includes a main control unit that outputs a control command, an intermediate unit, and a peripheral unit that performs processing according to the control command. When the control command output from the main control unit is a predetermined control command, the main control unit divides the predetermined data stored in the data storage means into the computer mounted on the machine.

Is added to a predetermined control command, and an authentication result transmission function for transmitting to the peripheral portion is realized.

  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 specific control command, and sends it to the intermediate unit. The intermediate unit uses the calculated value obtained by performing the binary operation using the predetermined data stored in the data storage means of the main control unit and the inspection value added to the specific control command. The main control unit is authenticated based on whether or not the calculation result obtained by performing the two-term calculation 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.

  Further, according to the present invention, since the authentication process is executed only by the intermediate 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 intermediate unit that executes the authentication process and the peripheral unit that performs the predetermined process are independent of each other, the authentication program and the predetermined process program are designed separately. be able to. This makes it easier and less time-consuming to design, implement the function, verify the function, etc. 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 intermediate part without changing the peripheral part for performing the predetermined processing, thereby reducing the number of authentication algorithms. The authentication algorithm can be changed by man-hours.

  Furthermore, according to the present invention, the main control unit divides predetermined data, and at the timing based on the number of divided data (number of divisions), a control command ( The authentication unit is switched at the time of the next authentication process at the timing based on the number of authentication data (number of joins) subjected to the binary operation when the authentication to the main control unit is successful. Switches the type of control command recognized as an authentication data addition command. 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 the intermediate unit can know only after successful authentication, the fraudster knows when to switch the type of 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 intermediate unit can be improved. Malfunctions can be detected, and execution of unauthorized control commands due to these can be prevented.

This speaker 277 is of a type that can output high, medium, and low sound areas, and outputs a high sound, medium sound, and low sound in a well-balanced manner during normal production. In such a case, control is performed to output a high sound region high so that the sound can be heard well around.

  Next, the electrical configuration of the pachinko gaming machine 1 according to Embodiment 1 of the present invention will be described with reference to the block diagram shown in FIG.

(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. Are connected to the second grand prize opening detection unit 224. 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. The normal winning opening detection unit 223 detects a game ball that has entered the normal winning opening 107 and transmits a detection result to the main control unit 10. The first grand prize opening detection unit 214 detects a game ball that has entered the first big prize opening 109c and transmits the detection result to the main control unit 10. The second grand prize winning port detection unit 224 detects a game ball that has entered the second grand prize winning port 129 c 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. During the winning game, the second big prize opening / closing solenoid 129b is energized to open the second big prize opening / closing door 129a, or the second start opening / closing solenoid 120b is energized by the winning of the normal symbol. 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 described in [1] to [5] below, but the encryption processing shown in [3] is executed as necessary.

[1] Determination of the number of divisions The main control unit 10 determines the number of divisions, which is a number for dividing predetermined data stored in advance in the ROM 10b, for example, predetermined program codes (instruction codes and fixed data). Hereinafter, as an example of the predetermined data, description will be given using a predetermined program code. The main control unit 10 uses, for example, a value generated by a random number generation circuit (not shown) or a random number generation program constituting the program code as a division number, or a value generated in other processing of the main control unit 10. The value can be referred to at a predetermined timing and the value can be used as the division number. In this case, the upper limit of the number of divisions may be set in advance. The means for executing the process for determining the number of divisions can correspond to, for example, the determination means 12 shown in FIG. In the first embodiment, the main control unit 10 determines the number of divisions using random numbers, but this is an example for determining the number of divisions, and determines the number of divisions without using random numbers. You may make it do. For example, the main control unit 10 holds a table for determining the number of divisions in advance, and the main control unit 10 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 same method is used in advance between the main control unit 10 and the intermediate unit 20 for the test value generation method (for example, the type of binary operation that satisfies the combining law used for the test value generation). Just keep it.

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

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

A method 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 generates data for authenticating the main control unit 10 when the output control command is a predetermined control command (for example, a jackpot command). Then, the generated data is added to the control command and transmitted to the intermediate unit 20. Here, data for authenticating the main control unit 10 added to the control command will be collectively referred to as “authentication data”. The authentication data is data obtained by performing encryption processing on each inspection value or these inspection values. Hereinafter, in the present embodiment, the authentication data is described as data obtained by performing encryption processing on the inspection value. However, the present invention is not limited to this, and the processing related to authentication is performed using the inspection value itself as authentication data. May be. In this case, it is not necessary to perform encryption processing on the inspection value in the main control unit, and it is not necessary to perform authentication data decryption processing when extracting the inspection value in the intermediate unit, thereby simplifying processing related to authentication. 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 Authentication Data The main control unit 10 performs an encryption process on each inspection value generated in the process [2] and adds authentication data to be added to the control command (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.

  When the main control unit 10 transmits each authentication data 303 obtained by performing encryption processing on each inspection value to the intermediate unit 20, each inspection value that has not been subjected to any processing is directly used as the intermediate unit. Compared with the case of transmitting to 20, it is possible to reduce the possibility that each inspection value is analyzed by a fraudster.

  Note that 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 error detection calculation for generating authentication data from each inspection value is made different. This also applies to processing related to intermediate processing information 304 in the intermediate 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 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 of authentication data generation)
An example of authentication data generation calculation is shown below.
An example of generating 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 generates the authentication data by performing the above-described encryption processing on the first inspection value.

The values of the control command data and the accompanying data to which this 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 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 authentication data may be generated by performing an encryption process on the data that includes at least one of the control command data transmitted along with the authentication data or the accompanying data and the inspection value. Further, the authentication data may include data related to control command data and accompanying data transmitted together with the authentication 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 authentication data using control command data and accompanying data that are sent together with the authentication data, even if the authentication data is reused by an unauthorized control unit, the authentication data and the control command cannot be matched. , Fraud can be detected. Further, even if the control command data is changed due to a malfunction, since the authentication is not successful, execution of the control command corresponding to the control command data changed due to the noise or the like can be prevented.

  When the authentication data includes data related to control command data and accompanying data, the main control unit 10 performs encryption processing by combining the data related to the control command data and accompanying data and the inspection value, and generates authentication data. Processing may be performed.

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

[4] Adding Data to Control Signal The main control unit 10 performs processing related to authentication when the output control command is a predetermined control command. That is, the main control unit 10 generates a plurality of inspection values when the control command to be output is a predetermined control command, performs encryption processing, and generates a plurality of authentication data. After that, the main control unit 10 adds the authentication data only to the control command data of the specific control command and the accompanying data among the control commands output from itself and transmitted to the effect control unit 203 via the intermediate unit 20. Then, a control signal with authentication data to which a plurality of authentication data is individually added is generated.

  Here, a specific control command to which authentication data is added when transmitting a control signal with authentication data to the intermediate unit 20 is referred to as an “authentication data addition command”. As the types of authentication data addition commands, a plurality of types of control commands may be selected in advance from control commands including predetermined control commands for which the main control unit 10 performs processing related to authentication. A plurality of types of control commands may be selected in advance from control commands other than the predetermined control command for which the control unit 10 is to perform processing related to authentication.

  The main control unit 10 selects a predetermined authentication data addition command from a plurality of types of control commands selected in advance as an authentication data addition command, and then adds authentication data according to a predetermined agreement based on the number of divisions. Switch the command type. The predetermined agreement is shared between the main control unit 10 and the intermediate unit 20, and includes, for example, the following {method 1} and {method 2}.

{Method 1}
For a plurality of control commands selected as authentication data addition commands, the order of adding authentication data is determined in advance. If the number of divisions is a predetermined value, the control command used for the next authentication data addition, that is, the type of the authentication data addition command is switched to the type of the control command in the next order, and the number of divisions is not the predetermined value. In this case, the type of the next authentication data addition command is continued without being switched. The predetermined value can be arbitrarily determined from the number of ranges that the number of divisions can take, such as “odd number” or “multiple of 3”.
As a specific example, it is decided that the type of the authentication data addition command is switched in the order of jackpot reach command → jackpot start command → jackpot command → jackpot end command, and the predetermined value is “odd”. For example, in the current authentication process, if the number of divisions is 3 and the authentication data addition command is a jackpot reach command, the number of divisions is an odd number. Therefore, in the next authentication process, the type of authentication data addition command is the jackpot reach command. Switch from the jackpot start command.

{Method 2}
For a plurality of control commands selected as authentication data addition commands, a predetermined value is associated with each control command. When the division number is a predetermined value, the type of the next authentication data addition command is switched to a control command associated with the predetermined value. When the division number is not the predetermined value, the next authentication data The type of additional command continues without switching.
As specific examples, a predetermined value = 2: a jackpot reach command, a predetermined value = 3: a jackpot start command, a predetermined value = 4: a jackpot command, and a predetermined value = 5: a jackpot end command are associated with each other. When the number of divisions for the current authentication process is 2, the authentication data addition command is a jackpot reach command. When the number of divisions is 3 for the next authentication process, the jackpot start command is an authentication data addition command. And

  A plurality of predetermined values may be associated with one control command. For example, predetermined value = 2 or 10: jackpot reach command, predetermined value = 3 or 11: jackpot start command, and the like. Further, for example, associations such as a predetermined value = 2 multiples: jackpot reach command, a predetermined value = multiples of 3: big hit start command, and a predetermined value = multiple of 5: jackpot command may be performed. In this case, when the division number is a common multiple, a control command for preferentially adding authentication data is determined in advance.

  As described above, the main control unit 10 switches authentication data addition commands based on the number of divisions. The number of divisions is a value that only the main control unit 10 can know. Therefore, the fraudster cannot know the number of divisions and cannot know the switching timing of the authentication data addition command. Therefore, it is possible to prevent the authentication data from being illegally exploited by an unauthorized person or the like. In the following description of Embodiment 1, it is assumed that {method 1} is adopted as the predetermined agreement.

[5] Transmission of control signal The main control unit 10 transmits a control signal with authentication data to the intermediate unit 20.

  Here, an example of a data format of a control signal transmitted from the main control unit 10 to the intermediate unit 20 will be described with reference to a schematic diagram shown in FIG. 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 authentication data to the intermediate unit 20, the main control unit 10, as shown in FIG. 5 (2), controls with authentication data including authentication data 303 in addition to control command data 301 and accompanying data 302. A signal 310 is generated and output. Although not shown in FIG. 5, the normal control signal 300 and the control signal with authentication data 310 include BCC (Block Check Character) and the like, as with the control signal transmitted in general data communication. Sometimes it is. The BCC is an error detection code added to each transmission block in order to check data errors that occur in the data transmission process. The same applies to the control signals with authentication data 311 and 312 to be described later, and the normal control signal 320 and the control signals with intermediate processing information 321, 322 and 323 shown in FIG.

  The control signal with authentication data is not limited to the control signal with authentication data 310 arranged in the order of the control command data 301, the accompanying data 302, and the authentication data 303 as shown in FIG. As shown in (3), the authentication data 303 is a control signal with authentication data 311 provided at the head of the control signal, or between the control command data 301 and the accompanying data 302 as shown in FIG. Alternatively, the control signal 312 with authentication data into which the authentication data 303 is inserted may be used. Further, the authentication data 303 may be output separately from the control command data 301 and the accompanying data 302. For example, after transmitting a control signal including jackpot command data, the authentication data 303 may be added at the time of the third control signal transmission.

  Thus, by including the authentication data 303 in the control signal, an increase in communication load between the main control unit 10 and the effect control unit 203 can be suppressed as compared with the case where the authentication data 303 is transmitted alone. . Further, by including the authentication data 303 in the control signal, it is possible to reduce the risk that the authentication data 303 is extracted from the communication data and analyzed as compared with the case where the authentication data 303 is transmitted alone. .

(Middle part)
The intermediate 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, the intermediate processing is as follows [1] to [6].
[1] Reception of Control Signal The intermediate unit 20 receives a normal control signal consisting only of the control command data 301 and the accompanying data 302 from the main control unit 10, or an authentication consisting of the control command data 301, the accompanying data 302 and the authentication data 303. Receive control signal with data. The intermediate unit 20 determines whether the received control signal is a normal control signal or a control signal with authentication data. This determination is made based on whether or not the control command included in the received control signal is an authentication data addition command to which authentication data is added by the main control unit 10. At this time, the intermediate unit 20 recognizes the type of the authentication data addition command according to a predetermined rule determined in advance with the main control unit 10.

  If the control command of the received control signal is not an authentication data addition command, the intermediate unit 20 transmits the received control signal to the effect control unit 203 as it is because it is a normal control signal. On the other hand, if the control command of the received control signal is an authentication data addition command, the received control signal is a control signal with authentication data, and the intermediate unit 20 continues the intermediate process. 6] is executed.

[2] Inspection Value Extraction The intermediate unit 20 extracts the authentication data 303 from the control signal with authentication data. Next, the intermediate unit 20 applies a decryption process corresponding to the encryption process used at the time of generating the authentication data to the extracted authentication data, and extracts a check value. The intermediate unit 20 stores the extracted inspection value in a predetermined storage area of the RAM 20c (hereinafter referred to as inspection value memory).

[3] Authentication The intermediate unit 20 performs a semi-group operation in the order shown below on all inspection values stored in the inspection value memory, so that the main control unit 10 is a regular main control unit. It authenticates whether or not.
The {1} intermediate 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 intermediate unit 20 reads an expected value stored in advance from a predetermined storage area of the ROM 20b.

The {3} intermediate unit 20 determines whether or not the calculation result in the process {1} (hereinafter referred to as a join result) matches the expected value read out in the process {2} (hereinafter referred to as a matching process). Called).
The intermediate unit 20 determines that the authentication is successful when the combination result matches the expected value.
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. Thereby, the intermediate unit 20 authenticates the validity of the main control unit 10.
On the other hand, if the combined result and the expected value do not match, the intermediate unit 20 determines that the authentication has not succeeded.

If the authentication is successful in the process {4} {3}, the intermediate unit 20 generates an authentication result indicating that the authentication is successful.
If the authentication is successful in the process {5} {3}, the intermediate unit 20 determines whether or not the number of inspection values (hereinafter referred to as the combined number) subjected to the combining process is a predetermined value. The predetermined value is the same as the predetermined value in a predetermined agreement (such as {method 1} or {method 2} described above) based on the number of divisions used by the main control unit 10 to switch the type of the authentication data addition command. belongs to. In the first embodiment, the above-described {Method 1} is adopted as the predetermined agreement, and the predetermined value is described as “odd number”.
When the number of {5-1} coupling is a predetermined value, the intermediate unit 20 refers to the type of control command recognized as the next authentication data addition command as a jackpot reach command → a jackpot start command → a jackpot command → a jackpot end command Switch in order. For example, when the jackpot reach command is recognized as an authentication data addition command and processing related to authentication is performed this time, the jackpot start command is recognized as an authentication data addition command next time. Thereafter, the intermediate unit 20 deletes all the inspection values stored in the inspection value memory.
If the {5-2} coupling number is not a predetermined value, the intermediate unit 20 continues without switching the type of the control command recognized as the next authentication data addition command. For example, this time, if the jackpot reach command is recognized as an authentication data addition command and processing related to authentication is performed, the jackpot reach command will be recognized as an authentication data addition command next time. Thereafter, the intermediate unit 20 deletes all the inspection values stored in the inspection value memory.

If authentication is not successful in the processing of {6} {3}, the intermediate unit 20 determines whether or not the number of authentication data received from the main control unit 10 is a predetermined number or more. The predetermined number is an arbitrary number within the range not less than the current number of connections (number of divisions) and not more than the number (maximum number of divisions) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided. is there.
{6-1} If the number of received authentication data is less than the predetermined number, the intermediate unit 20 determines that the authentication is not yet possible, and instead of the authentication result, as the authentication halfway data, for example, the authentication result An arbitrary value (for example, all 0 or all 1) having the same data length as the data length is generated.
{6-2} When the number of received authentication data is greater than or equal to the predetermined number, the intermediate unit 20 determines that the authentication has not succeeded, and generates an authentication result indicating that the authentication has not succeeded.

(Calculation example of expected value generation)
An expected value generation method will be described with reference to FIG.
The intermediate 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 intermediate unit 20 holds the same number of expected values as the number of half-group operations that are inspection value generation methods by the main control unit 10.

  The expected value used by the intermediate unit 20 for collation may be stored in advance in a predetermined storage area of the ROM 20b that constitutes the intermediate 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 intermediate unit 20. In addition, a coefficient necessary for calculating an expected value may be transmitted from an external device to the intermediate unit 20 or the expected value calculating 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 constitutes the intermediate unit 20 and is obtained from another component, the inspection value can be changed afterwards. It becomes.

  Thus, the intermediate unit 20 determines the type of control command recognized as the authentication data addition command based on the number of combinations. Since the number of connections when authentication to the main control unit 10 is successful matches the number of divisions, authentication processing can be performed in accordance with the switching of the type of authentication data addition command by the main control unit 10. In this way, by sharing the authentication data addition command switching rule between the main control unit 10 and the intermediate unit 20, the authentication process can be continued while changing the type of the control command to which the authentication data is added. .

  The intermediate unit 20 switches the type of control command recognized as an authentication data addition command based on the number of connections. The number of connections is a value that the intermediate unit 20 can know only after successful authentication. Therefore, the fraudster cannot know the number of combinations, and cannot know the switching timing of the control command recognized as the authentication data addition command. 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.

[4] Generation of intermediate processing information The intermediate unit 20 performs an encryption process in the same manner as when the main control unit 10 generates authentication data for the authentication result obtained by the authentication process of [3] or the authentication result. What has been applied is generated as intermediate processing information.

(Calculation example of intermediate processing information generation)
An example of calculation for generating intermediate processing information is shown below.
The intermediate unit 20 generates 1-byte long random numbers (range “0x00” to “0xFF”) with uniform random numbers having the same appearance probability of all values. For example, assume that a random number “0x4B” is generated by a uniform random number. When the authentication is successful, the intermediate unit 20 sets the data “0x4B” having the value of the least significant bit of the random number “0x4B” generated by the uniform random number as “1” as the intermediate processing information 304. On the other hand, if the authentication is not successful, the intermediate unit 20 sets the data “0x4A” having the value of the least significant bit of the random number “0x4B” generated by the uniform random number as “0” as the intermediate processing information 304.

[5] Generation of control signal with intermediate processing information The intermediate unit 20 adds intermediate processing information to a normal control signal including control command data 301 and accompanying data 302 to generate a control signal with intermediate processing information.

[6] Transmission of Control Signal The intermediate unit 20 transmits a control signal with intermediate processing information to the effect control unit 203. Details of these intermediate processes (the processes [1] to [6]) will be described later. For example, the means for executing the authentication process can correspond to the authentication means 22 shown in FIG.

  Here, an example of a data format of a control signal transmitted from the intermediate unit 20 to the effect control unit 203 will be described with reference to a schematic diagram shown in FIG. When the normal control signal 300 shown in FIG. 5 (1) is transmitted from the main control unit 10, the intermediate unit 20 includes control command data 301 and associated data 302 as shown in FIG. 6 (1). The normal control signal 320 is transmitted to the effect control unit 203 as it is. On the other hand, for example, when control signals with authentication data 310 to 312 shown in FIGS. 5 (2) to (4) are transmitted from the main control unit 10, the intermediate unit 20 is obtained from the authentication data 303. Perform intermediate processing such as authentication using each inspection value to generate intermediate processing information 304, for example, generate control signals 321 to 323 with intermediate processing information shown in FIGS. 6 (2) to (4), It transmits to the production control unit 203.

  In this way, by including the intermediate processing information 304 in the control signal, an increase in the communication load between the intermediate unit 20 and the effect control unit 203 can be suppressed as compared with the case where the intermediate processing information 304 is transmitted alone. it can. Also, by including the intermediate processing information 304 in the control signal, the risk that the intermediate processing information 304 is extracted and analyzed from the communication data is reduced as compared with the case where the intermediate processing information 304 is transmitted alone. be able to.

  Further, the intermediate processing information 304 may be added only to the control command data 301 of a predetermined control command. In this case, it is only necessary to add an authentication process related to a predetermined control command to the program executed by the effect control unit 203. Therefore, since it is not necessary to design a new timing for the entire program executed by the effect control unit 203, the timing design for adding the authentication function is compared with the case where the intermediate processing information 304 is added to all the control commands. Implementation of functions, verification of functions, etc. can be achieved more easily and with less man-hours.

(Production control unit)
The effect control unit 203 includes a CPU 203a, a ROM 203b, a RAM 203c, a VRAM 203d, and the like. The CPU 203a mainly controls the effects during the game, and based on a control command transmitted from the main control unit 10 via the intermediate unit 20 based on a program (program code) stored in advance in the ROM 203b. And effect processing. The ROM 203b stores in advance a program code for the CPU 203a to execute a lottery and a 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 via the intermediate unit 20, the effect control unit 203 performs a lottery based on the control command, and produces an effect background pattern, a reach effect pattern, and an appearance character. And the like are controlled, and the determined effect is controlled.
In addition, the symbol display unit 104 is connected to the output side of the effect control unit 203, and, for example, a symbol change effect display is developed on the symbol display unit 104 according to the content determined by the lottery.

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

  In addition to the processing outlined above, the effect control unit 203 executes the following processing related to authentication based on a program stored in advance in the ROM 203b when receiving a control signal with intermediate processing information. .

  The effect control unit 203 extracts the intermediate process information from the control signal with intermediate process information, performs a decoding process on the intermediate process information, and extracts an authentication result. The effect control unit 203 performs processing based on the control command when the authentication result indicates successful authentication. When the authentication result indicates unsuccessful authentication, a notification to that effect is made.

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

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

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

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

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

  The main control unit 10, the intermediate unit 20, the production control unit 203, the prize ball control unit 204, and the lamp control unit 205 having the above-described configuration are respectively different printed boards (main control board, intermediate board, production 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 intermediate unit 20 can be mounted on the same printed circuit board as the effect control unit 203. The prize ball control unit 204 can also be mounted on the same printed circuit board as the main control unit 10.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

By the way, as described above, gaming media are paid out regardless of the game due to fraudulent acts performed on the gaming machine or malfunction of the gaming machine due to noise or the like, and the gaming store suffers a great deal of damage. There is. Therefore, in order to prevent malfunctions of the gaming machine due to the above-described fraud and noise, in the pachinko gaming machine 1 according to the first embodiment, an intermediate unit 20 is provided between the main control unit 10 and the effect control unit 203. Provided.
In the first embodiment, when the output control command is a predetermined control command, the main control unit 10 generates authentication data corresponding to the number of divisions using a predetermined program code, and outputs these authentication data. This is added to the authentication data addition command and transmitted to the intermediate unit 20.

  The intermediate unit 20 authenticates whether or not the main control unit 10 is a regular main control unit using each inspection value obtained from the authentication data received from the main control unit 10. Next, the intermediate unit 20 transmits to the effect control unit 203 intermediate process information obtained by performing an encryption process on the authentication result obtained by the authentication process. Then, the effect control unit 203 performs processing according to the authentication result obtained from the intermediate processing information received from the intermediate unit 20. In this way, authentication processing is performed with the intermediate 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 intermediate unit 20, and the effect control unit 203 will be described. Hereinafter, processing related to authentication between the main control unit 10 and the intermediate unit 20 will be described with reference to the flowcharts shown in FIGS. 13 and 14, but authentication between the main control unit 10 and the prize ball control unit 204 will be described. The processing related to is performed in the same procedure.

  FIG. 13 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, that is, when the output control command becomes a predetermined control command, the determination result in step S62 is “YES”, and the main control unit 10 proceeds to step S63 to determine the number of divisions. The method for determining the number of divisions is arbitrary. The number of divisions may be determined before the transmission timing of authentication data.

  Next, the main control unit 10 divides a predetermined program code by the determined number of divisions, performs a semi-group operation on each of the divided data, calculates a test value (step S64), On the other hand, an encryption process is performed to generate authentication data (step S65). By this processing, the inspection value and authentication data for the number of divisions are generated. In addition, the inspection value generation method (such as the type of calculation used for generation) is determined in advance.

  Next, the main control unit 10 continues to transmit a normal control signal (step S67) until the transmission timing of the authentication data addition command is reached (step S66: NO). When it is the transmission timing of the authentication data addition command (step S66: YES), the main control unit 10 adds authentication data to the control command that is the authentication data addition command (step S68), and sends the control signal with authentication data to the intermediate unit 20. (Step S69). As the type of the authentication data addition command, a specific control command (for example, a jackpot reach command, a jackpot start command, etc.) to which the authentication data is added this time is determined in advance between the main control unit 10 and the intermediate unit 20. The main control unit 10 returns to step S66 and continues to transmit the control signal with authentication data until all the authentication data generated in step S65 is transmitted (step S70: NO). If there is untransmitted authentication data among the generated authentication data (step S70: NO), the main control unit 10 does not generate new authentication data even at a predetermined control command transmission timing. Always return to step S66 and continue to transmit the control signal with authentication data.

  When all the authentication data is transmitted (step S70: YES), it is determined whether or not the number of divisions determined in step S63 is a predetermined value (step S71). The predetermined value is a value determined when the type of the authentication data addition command is switched between the main control unit 10 and the intermediate unit 20, and is, for example, “odd” in the first embodiment. When the number of divisions is a predetermined value (step S71: YES), the main control unit 10 switches the type of the authentication data addition command (step S72), and ends the processing according to this flowchart. On the other hand, if the number of divisions is not a predetermined value (step S71: NO), the process according to this flowchart is terminated without switching the type of the authentication data addition command.

  The main control unit 10 may use only the predetermined control command as the type of the authentication data addition command. 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 the authentication data 303 is extracted from the control signal can be reduced. Further, even if the authentication data 303 is extracted from the control signal, the number of samples that can be acquired is small, so that the risk of the authentication data 303 being analyzed can be reduced.

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

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

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

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

  Next, processing related to authentication by the intermediate unit 20 will be described. FIG. 14 is a flowchart illustrating an example of processing related to authentication by the intermediate unit 20. First, the intermediate unit 20 determines whether or not a control signal as shown in FIG. 5 transmitted from the main control unit 10 has been received (step S81). If the determination result is “NO”, the intermediate unit 20 repeats the determination. And if the control signal transmitted from the main control part 10 is received (step S81: YES), the intermediate part 20 will progress to step S82.

  In step S82, the intermediate unit 20 determines whether the received control signal is a control signal with authentication data including the authentication data 303, depending on whether the control command of the received control signal is an authentication data addition command. . When the control command of the received control signal is an authentication data addition command (step S82: YES), the intermediate unit 20 proceeds to step S83 assuming that the received control signal is a control signal with authentication data.

  When the intermediate unit 20 receives the control signal with authentication data (step S82: YES), the intermediate unit 20 extracts the authentication data 303 from the control signal, further performs a decryption process, and acquires a check value (step S83). The intermediate unit 20 stores the acquired inspection value in the inspection value memory (step S84), and performs a semi-group operation (joining process) on all inspection values in the inspection value memory (step S85). In addition, what is necessary is just to determine previously the same kind of the half group calculation performed by step S85 as the main control part 10. FIG. If there is one inspection value in the inspection value memory, the process directly proceeds to step S86 without performing the combining process.

  Then, the intermediate unit 20 compares the operation result (combination result) with the expected value of the stored test value, and determines whether or not the combined result and the expected value match (step S86). When the combined result and the expected value match (step 86: YES), the intermediate unit 20 determines that the authentication with respect to the main control unit 10 is successful, and generates an authentication result indicating that the authentication is successful ( Step S87).

  Subsequently, the intermediate unit 20 determines whether or not the number of inspection values (the number of combinations) that is the target of the combination process when authentication is successful is a predetermined value (step S88). The predetermined value is a value determined when the type of the authentication data addition command is switched between the main control unit 10 and the intermediate unit 20. In the first embodiment, the predetermined value is the same “odd” as the main control unit 10. is there. If the number of connections is a predetermined value (step S88: YES), the intermediate unit 20 switches the type of control command recognized as an authentication data addition command (step S89), and deletes data in the test value memory (step S89). S90). If the number of connections is not a predetermined value (step S88: NO), the intermediate unit 20 deletes the data in the test value memory without switching the type of control command recognized as the authentication data addition command (step S90).

  Next, the intermediate unit 20 generates intermediate processing information 304 from the authentication result indicating the success of authentication (step S91). Next, the intermediate unit 20 includes a control signal (control signal with intermediate processing information) including the control command data 301 and the accompanying data 302 included in the control signal, and the intermediate processing information 304 obtained in the process of step S91. Is generated and transmitted to the effect control unit 203 (step S92), and the processing according to this flowchart ends.

  Also, in step S86, when the calculation result of the inspection value does not match the expected value (step S86: NO), the intermediate unit 20 proceeds to step S81 until receiving a predetermined number or more of authentication data (step S93: NO). Return and repeat the join process. When the authentication data of a predetermined number or more is received (step S93: YES), the intermediate unit 20 determines that the authentication to the main control unit 10 is unsuccessful and generates an authentication result indicating that the authentication is unsuccessful. Then (step S94), the process proceeds to step S91, and intermediate processing information 304 indicating unsuccessful authentication is generated. The predetermined number is an arbitrary number within the range not less than the current number of connections (number of divisions) and not more than the number (maximum number of divisions) in which the program code stored in the program code storage area 400 (see FIG. 4) can be divided. is there.

  If the control command of the received control signal is not an authentication data addition command in step S82, that is, if the received control signal is a normal control signal that does not include the authentication data 303 (step S82: NO), intermediate The unit 20 does not perform the authentication process and transmits the received normal control signal as it is to the effect control unit 203 (step S95), and ends the process according to this flowchart.

  The intermediate unit 20 may add the intermediate processing information 304 to the control command data 301 only when transmitting a predetermined control command to the effect control unit 203. In this case, since the authentication process of the main control unit 10 or the intermediate unit 20 is performed only when a predetermined control command is transmitted, the rate at which the processing load of the effect control unit 203 increases due to the authentication process can be suppressed. .

  In addition, since only the intermediate unit 20 performs authentication processing such as decryption of authentication data and verification between the inspection value and the expected value, the processing load of the CPU 203a constituting the effect control unit 203 does not increase. For this reason, it is possible to prevent problems such as a reduction in the processing speed of the effect control unit 203 and a smooth display for the effect.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 15 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 a control signal has been received from the intermediate unit 20 (step S101). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the intermediate part 20, the judgment result of step S101 will be "YES", and the production | presentation control part 203 will progress to step S102.

  In step S102, the effect control unit 203 determines whether or not the intermediate control information 304 is included in the received control signal. If the determination result in step S102 is “YES”, that is, if the intermediate control information 304 is included in the received control signal, the effect control unit 203 proceeds to step S103. Here, the determination as to whether or not the intermediate processing information 304 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 It is determined whether or not any bit constituting the associated data 302 or separately provided identification data (not shown) indicates that the intermediate processing information 304 is included, or in the control signal It may be determined whether the included control command data 301 is control command data of a predetermined control command set in advance for performing the authentication process.

  In step S103, the effect control unit 203 extracts the intermediate processing information 304 from the control signal, extracts the authentication result from the intermediate processing information 304, and then proceeds to step S104.

  In step S104, the effect control unit 203 determines whether or not the extracted authentication result indicates that the authentication has succeeded. If the determination result in step S104 is “YES”, that is, if the extracted authentication result indicates that the authentication is successful, the effect control unit 203 proceeds to step S105. In addition, when the determination result of step S102 is “NO”, that is, when the intermediate control information 304 is not included in the received control signal, that is, when it is a normal control signal, the effect control unit 203 Proceed to step S105.

  In step S <b> 105, the effect control unit 203 performs a process based on the control command data 301 and the accompanying data 302 and then ends a series of processes. On the other hand, if the determination result in step S104 is “NO”, that is, if the extracted authentication result does not indicate that the authentication has succeeded, the effect control unit 203 proceeds to step S106. In step S106, the production control unit 203 discards the control command data 301 and the accompanying data 302, and manages the symbol display unit 104, the lamp control unit 205, or the pachinko gaming machine 1 with a notification signal for notifying an illegal act. After the transmission to the center control device or the like, the series of processing ends. In the process of step S106, the effect control unit 203 may perform only one of data discarding and notification.

  Based on the received notification signal, the symbol display unit 104, the lamp control unit 205, and the like perform an effect of notifying the main control unit 10 that there is a risk of fraud. This effect is, for example, causing a character that does not normally appear in the symbol display unit 104 to appear, or causing a character that normally appears to appear in a manner different from the normal. Further, the brightness of the symbol display unit 104 may be changed, the color may be changed, or the lamp control unit 205 may be controlled to display a predetermined lamp. In any case, when the employee of the game shop passes in front of the pachinko gaming machine 1, it is only necessary to be aware of the state. This effect may be an effect that the customer does not notice the state or an effect that the customer can easily notice. If the production is easily noticed by the customer, fraud can be efficiently suppressed.

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

Next, a specific example of the authentication data addition command type switching process among the processes shown in FIGS. 13 and 14 will be described. FIG. 16 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the intermediate unit 20 (authenticated person).
In FIG. 16, the method for switching the type of the authentication data addition command is switched when the number of divisions is an odd number, and is not switched when the number is an even number ({Method 1} above). The order of switching the types of the authentication data addition commands is “big hit reach command → big hit start command → big hit command → big hit end command”. Note that the default authentication data addition command is a jackpot reach command.

  First, the main control unit 10 determines the number of divisions used for the current authentication process by an arbitrary method. For example, the current division number is determined to be 3 (step S111). The main control unit 10 divides a predetermined program code stored in the storage area of the ROM 10b into three blocks (storage areas), and determines in advance using the program code stored in each block. The inspection value is calculated by the half group operation method, and the inspection value is further encrypted to generate authentication data (step S112). Then, the main control unit 10 adds the generated authentication data to the jackpot reach command at the transmission timing of the jackpot reach command that is the default authentication data addition command (step S113), and sends the control signal with authentication data to the intermediate unit 20 (Step S114).

  Thereafter, the main control unit 10 switches the type of the authentication data addition command because the current division number is an odd number (step S115). Specifically, the main control unit 10 switches the next authentication data addition command from the jackpot reach command (hereinafter, reach command in FIG. 16) to the jackpot start command (hereinafter, start command in FIG. 16).

  Next, processing in the intermediate unit 20 will be described. The intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S116). Then, the intermediate unit 20 extracts authentication data from the control signal with authentication data (step S117), performs a decryption process, and acquires a check value (step S118). The intermediate unit 20 performs a combining process on the acquired inspection value using the same semi-group calculation method as that of the main control unit 10 (step S119), and collates the combined result with an expected value. If it matches the expected value, the intermediate unit 20 succeeds in authentication with the main control unit 10 (step S120). In this case, when combining processing is performed using three inspection values, it should match the expected value (number of connections = 3).

  Thereafter, the intermediate unit 20 switches the type of the control command recognized as the authentication data addition command because the current number of combinations is an odd number (step S121). Specifically, the intermediate unit 20 switches the next authentication data addition command from the jackpot reach command to the jackpot start command. This is the flow of a series of authentication processes.

  Turning to the description of the second authentication process, the main control unit 10 again determines the number of divisions used for the current authentication process by an arbitrary method. For example, the current division number is determined to be 4 (step S122). 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 calculates a test value using the program code stored in each block. Further, the verification value is subjected to encryption processing to generate authentication data (step S123). The main control unit 10 adds the generated authentication data to the jackpot start command at the transmission timing of the jackpot start command that is the authentication data addition command after switching (step S124), and adds the control signal with authentication data to the intermediate section. 20 (step S125).

  Thereafter, the main control unit 10 continues the previous authentication data addition command without switching the type of the authentication data addition command because the current division number is an even number (step S126). Specifically, the main control unit 10 keeps the type of authentication data addition command as a jackpot start command.

  Next, processing in the intermediate unit 20 will be described. The intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S127), and extracts the authentication data (step S128). Then, a decoding process is performed to obtain a check value (step S129), and a join process is performed on the acquired check value by the same semi-group calculation method as that of the main control unit 10 (step S130). When the combined result matches the expected value, the intermediate unit 20 succeeds in authentication with the main control unit 10 (step S131). In this case, when the joining process is performed using four inspection values, it should match the expected value (number of joins = 4).

  Thereafter, the intermediate unit 20 continues the type of the previous authentication data addition command without switching the type of the control command recognized as the authentication data addition command because the current number of combinations is an even number. Specifically, the intermediate unit 20 keeps the type of control command recognized as the authentication data addition command as the jackpot start command.

  As described above, in the first embodiment, the main control unit 10 divides the predetermined program code stored in the ROM 10b, and at the timing based on the number of pieces of data (divided number) of the divided program code next time. The type of the control command (authentication data addition command) to which authentication data is added during the authentication processing (such as a jackpot reach command or a jackpot start command) is switched, and the intermediate section 20 is displayed when the authentication to the main control section 10 is successful. At the timing based on the number of authentication data (combined number) subjected to the calculation, the type of control command recognized as an authentication data addition command at the next authentication processing is switched. The number of divisions is a value that only the main control unit 10 can know, and the number of combinations is a value that the intermediate unit 20 can know only after successful authentication. I can't know. As a result, it is possible to detect the above-mentioned fraudulent action and malfunction of the gaming machine, and it is possible to prevent the execution of unauthorized control commands resulting from these.

  In the first embodiment, the test value generation method is configured to set a specific half-group operation in advance, but is not limited to this, for example, based on the current number of divisions and the number of connections, One half group operation used for the next test value generation and combination processing may be selected from a plurality of half group operations. Specifically, for example, when the current division number is an odd number, the main control unit 10 selects the next half group calculation different from the currently used half group calculation, and when the current division number is an even number, The next half group calculation is the same as the half group calculation used this time. The intermediate unit 20 selects the next half-group operation and expected value different from the currently used half-group operation and expected value when the current number of connections is odd, and the next time when the current number of connections is an even number. The same half-group operation and expected value as the half-group operation and expected value used this time are selected. Note that the first half group calculation is set in advance to use the same method between the main control unit 10 and the intermediate unit 20.

  In this case, since the number of divisions and the number of connections are values that only the main control unit 10 and the intermediate unit 20 can know, the fraudster cannot know the switching timing of the half group operation used for generating the value of the authentication data. . Thereby, it is possible to detect the above-mentioned fraudulent act and malfunction of the gaming machine, and it is possible to prevent an illegal control command resulting from these from being executed. Note that only the encryption method may be switched without switching the type of the authentication data addition command and the generation method of the authentication data (half-group calculation method, encryption method, etc.) based on the number of divisions.

  The intermediate unit 20 may perform the authentication process using the authentication data at the time when a plurality of authentication data is received, instead of performing the authentication process every time the authentication data is received. In this case, for example, when the intermediate unit 20 receives the first authentication data together with the first control command data and the first associated data of the first authentication data addition command, the intermediate unit 20 performs the first process without performing the authentication process. The processing based on the first control command data and the first associated data of the authentication data addition command is performed. When the intermediate unit 20 receives the second authentication data together with the second control command data of the second authentication data addition command and the second accompanying data, the second control of the second authentication data addition command is performed. Before performing the process based on the command data and the second associated data, an authentication process using the first authentication data is performed. At this time, the intermediate 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. Thereby, it is possible to prevent authentication data 303 from being reused by an unauthorized main control unit, and to detect unauthorized actions and malfunctions more reliably, and prevent execution of unauthorized control commands caused by unauthorized actions and malfunctions. be able to.

  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 when a predetermined control command is received, and the processing load on the main control unit 10 and the effect control unit 203 increases. Can increase the rate of increase.

In addition, since the intermediate 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.

  Further, since authentication data 303 is added only to a specific control command as an authentication data addition command, it is only necessary to add an authentication process related to the specific control command to be an authentication data addition command to the program executed by the effect control unit 203. Good. Therefore, since it is not necessary to design a new timing over the entire program executed by the effect control unit 203, the timing design for adding the authentication function as compared with the case where the authentication data 303 is added to all the control commands, Implementation of functions, verification of functions, etc. can be realized more easily and with less work man-hours.

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

  For example, the processing capacity of the CPU 10 a constituting the main control unit 10 and the storage capacity of the ROM 10 b 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 complex or advanced encryption processing on each inspection value to the intermediate unit 20, and the intermediate unit 20 receives the above-mentioned The intermediate control information 304 obtained by subjecting the authentication result obtained by authenticating the main control unit 10 using each inspection value obtained from the authentication data 303 to relatively simple or low-level encryption processing is used as the effect control unit 203. Send to. Then, the effect control unit 203 performs processing according to the authentication result obtained from the intermediate processing information 304. 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, between the main control unit 10 and the intermediate unit 20 and the intermediate unit 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 each inspection value as the authentication data 303 as it is, or the authentication data 303 obtained by performing relatively simple or low-level encryption processing to the intermediate unit 20. The intermediate unit 20 performs a complicated or advanced re-encryption process on the authentication result obtained by authenticating the main control unit 10 using each inspection value obtained from the received authentication data 303, or obtains the authentication data 303 from the authentication data 303. An intermediate obtained by performing an intermediate operation that performs a more complex or advanced re-encryption process after performing a decryption process etc. on each inspection value Transmitting the management information 304 to effect control unit 203. Then, the effect control unit 203 performs processing according to the authentication result obtained from the intermediate processing information 304. 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, between the main control unit 10 and the intermediate unit 20 and the intermediate unit A security level can be maintained as much as possible between 20 and the effect control unit 203.

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

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

Hereinafter, a predetermined data dividing method in the main control unit 10 will be described in detail.
The main control unit 10 determines the amount of data (hereinafter referred to as “data amount”) constituting each data block that is 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.

(Example of inspection 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. 17 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 reads out the program code having the data amount determined in step S143, for example, from the top of the program code storage area 400, performs a semi-group operation, and calculates an inspection value (step S144). Authentication data is generated by performing encryption processing on the value (step S145). By this processing, the inspection value and authentication data for the number of divisions are generated. In addition, the inspection value generation method (such as the type of calculation used for generation) is determined in advance.

  Until the test value is generated using all the program codes in the program code storage area 400 (step S146: NO), the main control unit 10 always has to determine whether or not it is the transmission timing of the predetermined control command. Returning to step S143, the next data amount is determined, and the subsequent processing is repeated. Here, “using all the program codes in the program code storage area 400” means that the program codes in the program code storage area 400 are used without any duplication. When generating the second and subsequent inspection values, the main control unit 10, for example, the program code written in the area next to the program program code used for the previous inspection value generation by the amount determined in step S143. Read to generate inspection value. Note that when the final test value is generated, the data amount determined in step S143 may be insufficient, but the main control unit 10 generates the test value using only the program code that can be acquired. When the main control unit 10 generates inspection values using all the program codes in the program code storage area 400 (step S146: YES), the main control unit 10 obtains the number of generated inspection values, that is, the program code by dividing it by the data amount. The number of data blocks thus obtained is found, and the current division number is found.

  Next, the main control unit 10 continues the normal control signal (step S148) until the transmission timing of the authentication data addition command is reached (step S147: NO). When the transmission timing of the authentication data addition command comes (step S147: YES), the main control unit 10 adds the authentication data to the predetermined control command that is the authentication data addition command (step S149), and the control signal with authentication data is intermediate. It transmits to the part 20 (step S150). The type of the authentication data addition command is a specific control command (for example, a jackpot reach command or a jackpot start command) to which authentication data is added this time among predetermined control commands, in advance between the main control unit 10 and the intermediate unit 20. Arrange between them. The main control unit 10 returns to step S147 and continues to transmit the control signal with authentication data until all the authentication data generated in step S145 is transmitted (step S151: NO). Note that authentication is not performed immediately after generating authentication data, but after generating all authentication data (that is, after generating authentication data using all program codes in the program code storage area 400). Data transmission may be started.

  When all the authentication data is transmitted (step S151: YES), it is determined whether or not the number of divisions determined in step S146 is a predetermined value (step S152). The predetermined value is a value determined when the type of the authentication data addition command is switched between the main control unit 10 and the intermediate unit 20, and is, for example, “odd” in the second embodiment. When the number of divisions is a predetermined value (step S152: YES), the main control unit 10 switches the type of the authentication data addition command (step S153) and ends the processing according to this flowchart. On the other hand, if the number of divisions is not a predetermined value (step S152: NO), the process according to this flowchart is terminated without switching the type of the authentication data addition command.

  Processing related to authentication in the intermediate unit 20 and the effect control unit 203 is the same as in the first embodiment. That is, the intermediate unit 20 extracts authentication data from the control signal with authentication data transmitted from the main control unit 10, performs authentication processing using the authentication data, generates intermediate processing information using the authentication result, A control signal with processing information is transmitted to the effect control unit 203. The effect control unit 203 extracts the intermediate processing information from the control signal with intermediate processing information transmitted from the intermediate unit 20, restores the authentication result from the intermediate processing information, and performs various processes according to the authentication result.

Next, a specific example of the authentication data addition command type switching process among the processes shown in FIGS. 17 and 14 will be described. FIG. 18 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the intermediate unit 20 (authenticated person). 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.
In FIG. 18, the method of switching the type of the authentication data addition command is the number of data blocks obtained by dividing a predetermined program code at the time of test value generation, that is, switching when the number of divisions is odd, Are not switched (Method 1 above). The order of switching the types of the authentication data addition commands is “big hit reach command → big hit start command → big hit command → big hit end command”. Note that the default authentication data addition command is a jackpot reach command.

  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 the 4-byte, 3-byte, and 5-byte program codes in order from the top of the program code storage area 400, and uses each program code to inspect by a predetermined half-group operation method. A value is calculated, and the verification value is further encrypted to generate authentication data (step S162). Then, the main control unit 10 adds the generated authentication data to the jackpot reach command at the transmission timing of the jackpot reach command that is the default authentication data addition command (step S163), and sends the control signal with authentication data to the intermediate unit 20. (Step S164).

  Thereafter, the main control unit 10 switches the type of the authentication data addition command because the current division number is an odd number (step S165). Specifically, the main control unit 10 switches the next authentication data addition command from a jackpot reach command (hereinafter, reach command in FIG. 18) to a jackpot start command (hereinafter, start command in FIG. 18).

  Next, processing in the intermediate unit 20 will be described. The intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S166). Then, authentication data is extracted from the control signal with authentication data (step S167), and decryption processing is performed to obtain a check value (step S168). The intermediate unit 20 performs a combining process on the acquired inspection value using the same semi-group calculation method as that of the main control unit 10 (step S169), and collates the combined result with an expected value. If it matches the expected value, the intermediate unit 20 succeeds in authentication with the main control unit 10 (step S170). In this case, when combining processing is performed using three inspection values, it should match the expected value (number of connections = 3).

  Thereafter, the intermediate unit 20 switches the type of the control command recognized as the authentication data addition command because the number of couplings this time is an odd number (step S171). Specifically, the intermediate unit 20 switches the next authentication data addition command from the jackpot reach command to the jackpot start command. This is the flow of a series of authentication processes.

  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 for generating 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 S172). The main control unit 10 reads out 4-byte, 2-byte, 3-byte, and 3-byte program codes in order from the top of the program code storage area 400, calculates a test value using each program code, and further converts the test value into a test value. On the other hand, an encryption process is performed to generate authentication data (step S173). Then, the main control unit 10 adds the generated authentication data to the jackpot start command at the transmission timing of the jackpot start command that is the authentication data addition command after switching (step S174), and adds the control signal with authentication data to the intermediate section. 20 (step S175).

  Thereafter, the main control unit 10 continues the previous authentication data addition command without switching the type of the authentication data addition command because the current division number is an even number (step S176). Specifically, the main control unit 10 keeps the type of authentication data addition command as a jackpot start command.

  Subsequently, the intermediate unit 20 receives the control signal with authentication data transmitted from the main control unit 10 (step S177), and extracts the authentication data (step S178). Then, a decoding process is performed to obtain a check value (step S179), and a join process is performed on the acquired check value by the same semi-group operation method as that of the main control unit 10 (step S180). If the combined result matches the expected value, the intermediate unit 20 succeeds in authentication with the main control unit 10 (step S181). In this case, when the joining process is performed using four inspection values, it should match the expected value (number of joins = 4).

  Thereafter, since the number of couplings this time is an even number, the intermediate unit 20 does not switch the type of the control command recognized as the authentication data addition command, and continues the type of the previous authentication data addition command (step S182). Specifically, the intermediate unit 20 keeps the type of control command recognized as the authentication data addition command as the jackpot start command.

  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 intermediate part 20 and the production | presentation control part 203 showed the example set as a separate hardware structure, it is not limited to this.
For example, with respect to the first embodiment, one CPU has the functions of the CPU 20a configuring the intermediate unit 20 and the function of the CPU 203a configuring the effect control unit 203, and the intermediate unit 20 is configured. The program code stored in the ROM 20b and other fixed data and the program code stored in the ROM 203b constituting the effect control unit 203 and other fixed data are stored in one ROM. Also good. In this case, transmission and reception of data, a control signal with authentication data, and the like between the intermediate unit 20 and the effect control unit 203 function as a work area of the RAM 20c configuring the intermediate unit 20, and the effect 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. Thus, for example, the processing of the intermediate unit 20 may be performed with a dual CPU configuration.

  In the pachinko gaming machine of the third embodiment, the intermediate part and the effect control part are configured by a single piece of software, so that 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 intermediate unit are separated and independent on the software configuration, it is possible to develop the production control unit and the intermediate unit individually in parallel, for example, The following effects can be obtained.

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

2. Ease of introduction of authentication function and ease of porting to other models Since the authentication process in the intermediate part is independent of the existing game process, transmission of authentication information between the authentication process in the intermediate 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 implementation of the intermediate part. Therefore, there is a high possibility that a slight design change is required when the middle part is shifted from the previous model to the new model.

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

4). Ease of change of authentication method When changing the authentication method or upgrading the authentication algorithm, only the main control unit and the intermediate unit need to be changed or upgraded. No need.

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

6). Reduction of processing load of the production control unit When the authentication function to be implemented in the intermediate unit is implemented by software of the production control unit, the processing load of 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.

In this case, the prize ball control unit 204 is not provided with an informing means, but since bidirectional communication is possible between the main control unit 10 and the prize ball control unit 204, the authentication is unsuccessful. The prize ball control unit 204 may transmit data indicating that the authentication has failed together with the control command data 301 and the accompanying data 302 to the main control unit 10. Then, the main control unit 10 transmits the data indicating the unsuccessfulness to the effect control unit 203 via the intermediate unit 20, and the effect control unit 203 based on the data indicating the unsuccessful, Notify that fraud has occurred.
