It carried out about the authentication method in.

Of the fraudulent acts that are performed on gaming machines and forcibly pay out medals, game balls, etc. (hereinafter referred to as game media) regardless of the game, the main control board on which the main control unit is mounted or the peripheral part For example, the followings are related to the mounted peripheral board.
(1) Replacing an authorized main control board with an unauthorized main control board (2) A ROM storing a legitimate program executed by the CPU mounted on the main control board and an unauthorized program obtained by falsifying the above program are stored. (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. and to provide the gaming machine can reduce the processing load and the authentication method.

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

  Furthermore, according to the present invention, the main control unit transmits the correction data at a timing based on the number of divisions of the predetermined data, and the subsequent unit performs the binary operation when the authentication to the main control unit is successful. The expected value is corrected at the timing based on the number of authentication data (number of connections). Since the number of divisions and the number of combinations are values known only by the main control unit and the subsequent stage unit, the fraudster cannot know the transmission timing of the correction data used for correcting the expected value. As a result, the expected value held by the subsequent stage unit can be corrected without being known to the fraudster, and the above-mentioned fraudulent act and malfunction of the gaming machine can be detected. Authentication processing between the main control unit and the subsequent stage unit The strength of can be improved.

(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.

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. Processing related to this authentication is as shown in [1] to [6] below, but the encryption processing shown in [4] 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 subsequent stage unit 20 for the inspection value generation method (for example, the type of binary operation that satisfies the combining law used to generate the inspection value). 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”.

[3] Generation of Correction Value The main control unit 10 corrects the expected value when the subsequent unit 20 needs to correct the expected value held in advance for authenticating the main control unit 10. A correction value is generated for this purpose. The case where the expected value needs to be corrected is when the means for generating the inspection value is changed. For example, a predetermined program code in the data storage means 11 used for generating the inspection value is changed. In some cases, the type of semi-group operation used to generate the inspection value may be changed. Note that the above changes are made when a part of the main control unit 10 such as the data storage unit 11 and the determination unit 12 is changed, when the main control unit 10 itself is changed, or when the main control unit 10 is mounted. In some cases, the board is a control board that can be replaced with another control board, and the main control board 10 is replaced with another control board by an authorized user. In addition, each change at this time includes replacing the object to be changed with another object having the same configuration.

  When there is such a change, a predetermined program code stored in the data storage means 11 of the main control unit 10 used for generating the inspection value and a method of half group operation as a method for generating the inspection value are changed. As a result, the inspection value to be generated also differs before and after the change. At this time, as will be described later, if the expected value stored in the calculation value storage means 21 of the rear stage unit 20 remains the value generated by the predetermined program code and the semi-group calculation method before the change, Even if the control unit 10 is legitimate, its validity cannot be authenticated, and therefore the expected value held by the subsequent stage unit 20 needs to be corrected together with the change in the means for generating the test value as described above. There is.

  The correction value is, for example, difference data between an expected value corresponding to the inspection value before the change and an expected value corresponding to the inspection value after the change. The difference data is generated, for example, by performing four arithmetic operations or logical operations using the expected value before the change and the expected value after the change. By making the correction value difference data from the expected value before the change rather than the expected value itself after the change, for example, even if the control signal is stolen by an unauthorized person, the expected value is not deciphered. Can be improved.

  When it is necessary to correct the expected value, the main control unit 10 can be configured to generate a correction value at the time of processing related to the authentication after the next time based on the current division number. Specifically, for example, in the RAM 11c of the main control unit 10, information (hereinafter referred to as correction timing information) related to the timing (hereinafter referred to as correction timing) for generating and transmitting a correction value is stored (hereinafter referred to as correction timing information). A correction timing information storage area) is provided, and the current division number is stored as correction timing information. Then, the main control unit 10 determines when the correction timing is to be performed among the processes related to the next and subsequent authentications while updating the value of the correction timing information according to a predetermined agreement based on the number of divisions. When the correction timing information is a specific number (for example, 0), it is determined that it is the correction timing, and a correction value is generated. Configure as follows. As for the processing related to authentication in the main control unit 10 immediately after the expected value needs to be corrected, the correction value is first generated and transmitted, and the subsequent processing is performed in the correction timing information as described above. The correction timing is determined in accordance with the value and is determined in advance with the subsequent stage unit 20.

  Here, the predetermined agreement refers to, for example, the correction timing information storage area at the time of processing related to authentication, and if the value of the correction timing information is not a specific number (for example, 0), the value of the correction timing information is On the other hand, when the value of the correction timing information is updated by performing a specific calculation (for example, every time the authentication process succeeds, the value of the correction timing information is decreased by 1), and the value of the correction timing information is a specific number The value of the correction timing information is deleted. Note that the range that the value of the correction timing information can take is based on the range that the number of divisions can take.

  Since the division number is a value that only the main control unit 10 knows, the correction data other than the main control unit 10 cannot know the correction timing of the main control unit 10, and the correction data is illegally obtained by an unauthorized person or the like. It can be prevented from being exploited.

  On the other hand, in the first embodiment, as will be described later, the main control unit 10 authenticates the main control unit 10 when the output control command is a predetermined control command (for example, a jackpot command). , And the generated data is added to the control command and transmitted to the rear stage unit 20 via the effect control unit 203. Here, data for authenticating the main control unit 10 added to the control command will be collectively referred to as “authentication data”. In addition, the main control unit 10 generates data for correcting the expected value of the rear stage unit 20, adds the generated data to the control command, and transmits the data to the rear stage unit 20 via the effect control unit 203. Similar to “authentication data”, data for correcting the expected value will be collectively referred to as “correction data”. The authentication data or the correction data is data obtained by performing encryption processing on each inspection value or correction value, or these inspection values or correction values. Hereinafter, in the first embodiment, the authentication data or the correction data is described as data obtained by performing encryption processing on the inspection value or the correction value. However, the present invention is not limited to this, and the inspection value or the correction data is described. Processing related to authentication may be performed using the value itself as authentication data. In this case, the main control unit does not need to perform an encryption process on the inspection value or the correction value, and the post-stage unit 20 does not need to perform the authentication data or the correction data decryption process when extracting the inspection value or the correction value. Therefore, it is possible to simplify the process related to authentication and suppress an increase in processing load.

  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.

[4] Generation of Authentication Data and Correction Data The main control unit 10 performs an encryption process on each inspection value or correction value generated in the processes [2] and [3], and generates a control command (control command data). Authentication data or correction data to be added to (and associated data). The authentication data and the correction data are generated in a format (data format or the like) that cannot be identified. Here, as an encryption method, for example, a relatively simple method such as Caesar encryption, single substitution encryption, or enigma can be employed. The same applies to the encryption method used below. Caesar encryption is an encryption method in which characters constituting a message (plain text) are encrypted by shifting by a certain number of characters. Single substitution cryptography is an encryption scheme that encrypts characters by converting the characters constituting the plaintext into other characters. Enigma is set with Enigma using key encryption key, Encrypt communication key with Enigma, Enigma Enigma with communication key, plaintext encryption, encrypted communication key and encrypted This is an encryption method through a process of generating a communication text by combining plaintext.

  In the main control unit 10, when each authentication data or correction data obtained by performing encryption processing on each inspection value or correction value is transmitted to the rear stage unit 20 via the effect control unit 203, any The possibility that each inspection value or correction value is analyzed by a fraudulent person can be reduced as compared with the case where each inspection value or correction value that has not been processed is transmitted to the subsequent stage 20 as it is.

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

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

  Further, the main control unit 10 prepares a plurality of methods such as encryption processing in advance, and a plurality of encryption processing based on the current number of divisions (number of data blocks) determined in the processing [1]. One encryption process used for generation of the next authentication data or correction data may be selected from among the above. 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 or the correction data may be generated by performing encryption processing by combining at least one of the control command data and the accompanying data transmitted together with the authentication data or the correction data and the inspection value or the correction value. Further, the authentication data or the correction data may include control command data transmitted along with the authentication data or the correction data and data related to the accompanying data. Data related to control command data and accompanying data is the above processing, control using a hash function, parity check, cyclic redundancy check (CRC), checksum, etc. for control command data and accompanying data. It is the value obtained by going.

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

  When the authentication data or the correction data includes the data related to the control command data or the accompanying data, the main control unit 10 performs the encryption process by combining the data related to the control command data or the accompanying data and the inspection value or the correction value. A process of generating authentication data or correction data 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.

[5] Adding data to the control signal The main control unit 10 adds authentication data or correction data to the control command data and accompanying data transmitted to the rear stage unit 20 via the effect control unit 203, and performs control with authentication data. A control signal with a signal or correction data is generated.

[6] Transmission of control signal The main control unit 10 transmits a control signal with authentication data or a control signal with correction data to the subsequent unit 20.

  Here, an example of a data format of a control signal transmitted from the main control unit 10 to the rear stage unit 20 via the effect control unit 203 will be described with reference to a schematic diagram shown in FIG. As shown in FIG. 5 (1), the normal control signal 300 output from the main control unit 10 includes control command data 301 and accompanying data 302. The control command data 301 is data unique to the control command. The accompanying data 302 is data accompanying the control command data 301, and is control data necessary for executing processing corresponding to the control command data 301 such as data indicating the current gaming state, for example.

  On the other hand, when the main control unit 10 transmits the authentication data to the subsequent stage unit 20 via the effect control unit 203, the authentication data 303 is added to the control command data 301 and the accompanying data 302 as shown in FIG. Is generated and output. When the main control unit 10 transmits correction data to the subsequent stage unit 20 via the effect control unit 203, the correction data 304 is added to the control command data 301 and the accompanying data 302 as shown in FIG. A control signal with correction data 311 including is generated and output. Although not shown in FIG. 5, the normal control signal 300, the authentication data-added control signal 310, and the correction data-added control signal 311 include BCC as well as control signals transmitted in general data communication. (Block Check Character) may be included. 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 control signals 312 and 313 with authentication data to be described later.

  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 (4), the authentication data 303 is the 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 or the correction data 304 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 correction data 304 may be added when the first control signal is transmitted, and the authentication data 303 may be added when the third control signal is transmitted.

  As described above, by including the authentication data 303 or the correction data 304 in the control signal, communication between the main control unit 10 and the effect control unit 203 is compared with the case where the authentication data 303 or the correction data 304 is transmitted alone. An increase in load can be suppressed. Further, by including the authentication data 303 or the correction data 304 in the control signal, the authentication data 303 or the correction data 304 is extracted from the communication data as compared with the case where the authentication data 303 or the correction data 304 is transmitted alone, The risk of being analyzed can be reduced.

  Further, dummy data (not shown) having the same size as that of the correction data 304 and the authentication data 303 may be added to the normal control signal 300 that does not include the authentication data 303 and the correction data 304. Here, the dummy data is data that is not used for the correction process or the authentication process. By doing in this way, the data size of the normal control signal 300 can be made comparable to the control signal with authentication data 310 and the control signal with correction data 311. For this reason, it is possible to prevent a third party from seeing a control signal to which the authentication data 303 or the correction data 304 is added due to a difference in data size.

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

In the first embodiment, this intermediate processing is as follows [1] to [7].
[1] Reception of control signal with authentication data or control signal with correction data The post-stage unit 20 receives authentication data including control command data 301, accompanying data 302, and authentication data 303 from the main control unit 10 via the effect control unit 203. A control signal with correction data including a control signal or control command data 301, accompanying data 302, and correction data 304 is received.

When the post-stage unit 20 receives the control signal with authentication data or the control signal with correction data, the post-stage unit 20 is added to the received control signal because the authentication data and the correction data are generated in a format that cannot be distinguished from each other. From the format of the data (authentication data or correction data), it is not possible to determine whether to perform authentication processing or correction processing described later.
Therefore, an area (hereinafter referred to as a correction timing information storage area) for storing information (hereinafter referred to as correction timing information) relating to the timing for performing the correction process (hereinafter referred to as correction timing) is provided in the RAM 20c of the rear stage unit 20. The number of connections described later is stored as correction timing information. Then, the post-stage unit 20 determines whether the process related to authentication from the next time is the correction timing while updating the value of the correction timing information according to a predetermined agreement based on the number of combinations. If the correction timing information is a specific number (for example, 0), it is determined that it is the correction timing and correction processing is performed. If the correction timing information is not a specific number, it is determined that the correction timing is not the correction timing and authentication processing is performed. Configure. As for the process related to authentication in the post-stage unit 20 immediately after the expected value needs to be corrected, the correction process is first performed, and the subsequent processes are performed according to the correction timing information value as described above. It is determined in advance between the determination and the main control unit 10.

  Here, the predetermined agreement refers to, for example, the correction timing information storage area at the time of processing related to authentication, and if the value of the correction timing information is not a specific number (for example, 0), the value of the correction timing information is When a specific calculation (for example, every time the authentication process is successful, the value of the correction timing information is decreased by 1) is performed to update the value of the correction timing information, and the value of the correction timing information is a specific number Is to delete the value of the correction timing information. Note that the range that the correction timing information value can take is based on the range that the coupling number can take.

  In the first embodiment, the “correction timing” is either a timing at which the main control unit 10 generates and transmits a correction value or a timing at which the subsequent stage unit 20 performs the correction process. Hereinafter, the term “correction timing” is used without distinction unless otherwise specified. The same applies to “correction timing information” and “correction timing storage area”. In addition, in the intermediate processing described in [2] to [7] below, [4] describes the case where the current time is the correction timing and correction processing is performed, and this time is not the correction timing except for [4]. The case where authentication processing is performed is described.

[2] Examination Value Extraction The post-stage unit 20 extracts the authentication data 303 from the control signal with authentication data. Next, the post-stage 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 rear stage unit 20 stores the extracted inspection value in a predetermined storage area of the RAM 20c (hereinafter referred to as inspection value memory).

[3] Authentication The post-stage unit 20 performs a semi-group operation on all the test values stored in the test value memory in the order shown below, so that the main control unit 10 is a regular main control unit. It authenticates whether or not.
The {1} rear stage unit 20 performs a half group operation (hereinafter referred to as a combining process) using all the inspection values stored in the inspection value memory.
{2} The rear stage unit 20 reads an expected value stored in advance from a predetermined storage area of the ROM 20b.

The {3} latter-stage unit 20 determines whether or not the operation result in the process {1} (hereinafter referred to as a combination result) matches the expected value read in the process {2} (hereinafter referred to as a collation process). Called).
The post-stage unit 20 determines that the 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. At this time, that is, when the authentication with respect to the main control unit 10 is successful, the number of inspection values (hereinafter referred to as the number of connections) subjected to the combination processing and the number of divisions naturally match. As a result, the post-stage unit 20 authenticates the validity of the main control unit 10.
On the other hand, the post-stage unit 20 determines that the authentication is not successful when the combination result and the expected value do not match.

When the authentication is successful in the processing of {4} {3}, the subsequent stage unit 20 generates an authentication result indicating that the authentication is successful, and erases the inspection value stored in the inspection value memory.
If the authentication is successful in the process {5} {3}, the rear stage unit 20 determines whether or not the next correction timing has been determined. This determination is made by referring to the correction timing information storage area in the RAM 20c and whether or not the value of the correction timing information is stored (whether the correction timing information storage area is not cleared).
When the value of {5-1} correction timing information is stored, the value of the correction timing information is a value excluding a specific number (for example, 0), and the rear stage unit 20 is specified as the value of the correction timing information. The value of the correction timing information is updated by performing the above calculation (for example, minus 1).
If the value of {5-2} correction timing information is not stored, the subsequent stage unit 20 stores the number of combinations at the time of the current combination process that has been successfully authenticated as the value of the correction timing information in the correction timing information storage area. .

If authentication is not successful in the processing of {6} {3}, the post-stage 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 post-stage 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} If the number of received authentication data is greater than or equal to the predetermined number, the rear stage 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 subsequent stage unit 20 holds, as an expected value, a value obtained by performing a semigroup operation on the entire predetermined program code to be divided stored in the program code storage area 400. For example, the expected value in the case of method A is “0x4E”, which is the sum of “0x01” to “0x0C”. Further, the expected value in the case of the method B is “0x0C” which is an exclusive OR of “0x01” to “0x0C”. The rear stage unit 20 holds the same number of expected values as the number of half-group operations that are the inspection value generation method by the main control unit 10.

  The expected value used by the subsequent stage unit 20 for collation may be stored in advance in a predetermined storage area of the ROM 20b that configures the subsequent stage unit 20 at the time of manufacture, for example. It is good also as transmitting to 20. Examples of other components include a prize ball control unit 204 and a dedicated processing unit (hereinafter referred to as an expected value calculation unit) for generating an expected value. Note that the expected value calculation unit may transmit the expected value stored in advance to the subsequent unit 20. In addition, a coefficient necessary for calculating an expected value may be transmitted from an external device to the subsequent stage unit 20 or the expected value calculation unit via an external connection interface (not shown). As described above, if the expected value is not stored in advance in the predetermined storage area of the ROM 20b that configures the rear stage unit 20 and acquired from another component unit, the inspection value can be changed afterwards. It becomes.

[4] Correction Process The post-stage unit 20 extracts correction data 304 from the control signal with correction data. Then, the post-stage unit 20 performs a decryption process corresponding to the encryption process used when generating the correction data on the extracted correction data, and extracts a correction value. Next, the post-stage unit 20 corrects the expected value in the ROM 20b using the extracted correction value. The correction value is difference data between the expected value corresponding to the inspection value before the change and the expected value corresponding to the inspection value after the change, and the main control unit 10 uses the correction value to make a difference with respect to the expected value. A predetermined correction calculation (for example, adding a correction value to the changed expected value) corresponding to the calculation method used to generate the data is performed.

  After the correction process, the post-stage unit 20 erases the value of the correction timing information stored in the correction timing information storage area. When the value of the correction timing information is deleted, the subsequent stage unit 20 stores the number of combinations at the time of the combination process as the value of the correction timing information in the correction timing information storage area in the next authentication process. .

  In this way, the post-stage unit 20 sets the value of the correction timing information based on the number of connections, and updates it during the process related to authentication. Since the number of combinations when the authentication to the main control unit 10 is successful matches the number of divisions, the rear-stage unit 20 can perform correction processing in accordance with the correction value generation and transmission timing of the main control unit 10. Therefore, the post-stage unit 20 can continue the authentication process for the regular main control unit 10 even when the expected value is changed.

  Further, the main control unit 10 or the subsequent stage unit 20 sets the value of the correction timing information based on the division number or the coupling number. The number of divisions is a value recognized only by the main control unit 10, and the number of connections is a value known by the subsequent unit 20 only after the authentication is successful. Therefore, the fraudster cannot know the number of divisions and the number of connections, and cannot know the correction timing. Thereby, it can be detected that an unauthorized control unit is inserted between the main control unit 10 and the effect control unit 203, and unauthorized processing by the unauthorized control unit can be prevented.

[5] Generation of Authentication Unsuccessful Signal When the authentication result generated in the process of [3] is a result indicating that the authentication has not been successful, the latter stage unit 20 authenticates based on the result of the authentication failure. Generate a failure signal. At this time, the post-stage unit 20 may perform an encryption process on the authentication unsuccessful signal in the same manner as when the main control unit 10 generates the authentication data.

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

(Production control unit)
The effect control unit 203 includes a CPU 203a, a ROM 203b, a RAM 203c, a VRAM 203d, and the like. The CPU 203a mainly controls the effect during the game, and executes the effect lottery and effect processing based on the control command transmitted from the main control unit 10 based on the program (program code) stored in advance in the ROM 203b. . The ROM 203b stores in advance a program code for the CPU 203a to execute a lottery and a production process of production and past production patterns. The RAM 203c functions as a work area for data and the like in arithmetic processing performed when the CPU 203a executes lottery and effect processing of effects. Image data to be displayed on the symbol display unit 104 is written in the VRAM 203d.

When the effect control unit 203 receives a control command related to the effect transmitted from the main control unit 10, the effect control unit 203 performs a lottery based on the control command and finalizes effects such as an effect background pattern, a reach effect pattern, and an appearance character. At the same time, the determined effect is controlled.
In addition, the symbol display unit 104 is connected to the output side of the effect control unit 203, and, for example, a symbol change effect display is developed on the symbol display unit 104 according to the content determined by the lottery.

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

  In addition to the processing outlined above, the effect control unit 203 is based on a program stored in advance in the ROM 203b in accordance with the type of control signal transmitted from the main control unit 10 or the subsequent stage unit 20 as follows. The processing related to authentication shown in [1] to [4] is executed.

[1] Reception of Control Signal The effect control unit 203 determines whether the control signal transmitted from the main control unit 10 is a normal control signal including only the control command data 301 and the accompanying data 302, or the control command data 301 and the accompanying data 302. It is determined whether the control signal with authentication data is added with the authentication data 303 or the control signal with correction data with the correction data 304 added to the control command data 301 and the accompanying data 302.
[2] Execution of processing based on control command When the control signal transmitted from the main control unit 10 is a normal control signal, the effect control unit 203 performs processing based on the control command as described above.
[3] Transmission of control signal with authentication data or control signal with correction data to subsequent stage The effect control unit 203 is configured such that the control signal transmitted from the main control unit 10 is a control signal with authentication data or a control signal with correction data. In this case, the control signal with authentication data or the control signal with correction data is transmitted to the subsequent stage 20 as it is. Note that the authentication data 303 is extracted from the control signal with authentication data and only the authentication data is transmitted to the subsequent stage unit 20, or the correction data 304 is extracted from the control signal with correction data and only the correction data is transmitted to the subsequent stage unit 20. Or you may.
[4] Processing Based on Authentication Unsuccessful Signal When the production control unit 203 receives an authentication unsuccessful signal from the subsequent unit 20, the effect control unit 203 notifies that the authentication is unsuccessful.
The details of the processing related to authentication will be described later.

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

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

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

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

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

  The main control unit 10, the rear stage unit 20, the stage control unit 203, the prize ball control unit 204, and the lamp control unit 205 having the above-described configuration are respectively different printed boards (main control board, intermediate board, stage control board, (Prize ball control board, lamp control board) Among these, “peripheral board” is used as a general term for the intermediate board, the effect control board, the prize ball control board, and the lamp control board. For example, the rear stage unit 20 can be mounted on the same printed circuit board as the effect control unit 203. The prize ball control unit 204 can also be mounted on the same printed circuit board as the main control unit 10.

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

Processing including control command transmission by the main control unit 10 to the rear stage unit 20 and the prize ball control unit 204 will be described with reference to the flowcharts shown in FIGS. 6 and 7.
First, the main control unit 10 executes an initial setting process associated with power-on of the pachinko gaming machine 1 (step S1), and then proceeds to step S2. When the pachinko gaming machine 1 is turned on, the peripheral board starts up and performs initialization of the RAM area in order to reliably capture the control command received from the main control board by the peripheral board. After that, the main control board is configured to stand up. For example, the main control unit 10 sets a predetermined value in the stack pointer as an initial setting process, and waits for the rear stage unit 20, the production control unit 203, and the prize ball control unit 204 to enter a standby state. And wait for a predetermined time (for example, about 1 second).

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

  The power-on command indicates a control command for executing processing associated with power-on after power-on. After each control board is started up, the main control unit 10 performs the effect control unit 203, the prize ball control unit 204, and the effect. Control command to be transmitted to the post-stage unit 20 and the lamp control unit 205 via the control unit 203, and initial control information for controlling the game at the start-up after power-on, for example, control mode, backup data, etc. Or a control command for controlling the initial effect display, for example, a control command for starting various demonstration displays such as a customer waiting demonstration. The power-on command also includes a control command for transmitting the control mode, backup data, etc., which is executed when the reset button of the gaming machine is pressed.

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

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

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

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

  On the other hand, if the determination result in step S7 is “NO”, that is, the first start port detection unit 221 does not detect the game ball entering the first start port 105, and the second start port detection unit 225 If no game ball has entered the second start port 120, the main control unit returns to step S4 and repeats the processing from step S4.

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

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

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

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

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

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

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

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

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

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

First, the symbol variation process by the effect control unit 203 will be described with reference to the flowchart shown in FIG.
Whether or not the effect control unit 203 has received either a jackpot reach command (see step S13 shown in FIG. 7) or a miss reach command (see step S19 shown in FIG. 7), which is a symbol variation command, from the main control unit 10. Is determined (see step S31 in FIG. 9). When the determination result is “NO”, the effect control unit 203 repeats the determination. Then, when either the jackpot reach command or the miss reach command is received, the determination result in step S31 is “YES”, and the effect control unit 203 proceeds to step S32.

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

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

  In step S36, the effect control unit 203 determines whether or not a symbol stop command (see steps S15 and S21 shown in FIG. 7) has been received from the main control unit 10. If the determination result in step S36 is “NO”, that is, if the symbol stop command has not been received, the effect control unit 203 returns to step S35 and repeats the processing after step S35.

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

Next, the process at the time of the big hit by the production | presentation control part 203 is demonstrated with reference to the flowchart shown in FIG.
First, the effect control unit 203 determines whether or not a jackpot start command (see step S16 shown in FIG. 7) is received from the main control unit 10 (see step S41 in FIG. 10). When the determination result is “NO”, the effect control unit 203 repeats the determination. When the jackpot start command is received, the determination result in step S41 is “YES”, and the effect control unit 203 proceeds to step S42.

  In step S42, the effect control unit 203 transmits a jackpot start processing command to the symbol display unit 104 and the lamp control unit 205, and then proceeds to step S43. In step S43, the effect control unit 203 determines whether or not a round-by-round jackpot command (see step S17 shown in FIG. 7) has been received from the main control unit 10. When the determination result is “NO”, the effect control unit 203 repeats the determination. And if the jackpot command according to round is received, the judgment result of step S43 will be "YES", and the production | presentation control part 203 will progress to step S44.

  In step S44, the effect control unit 203 transmits to the symbol display unit 104 or the lamp control unit 205 a round-by-round processing command corresponding to the received round-by-round jackpot command, and then proceeds to step S45. In step S45, it is determined whether or not a jackpot end command (see step S18 shown in FIG. 7) has been received from the main control unit 10. When the determination result is “NO”, the effect control unit 203 repeats the determination. When the jackpot end command is received, the determination result in step S45 is “YES”, and the effect control unit 203 proceeds to step S46. In step S46, the effect control unit 203 transmits the received jackpot end command to the symbol display unit 104 and the lamp control unit 205, and then ends the series of processes.

Next, lamp control processing by the lamp control unit 205 will be described. Here, processing when a symbol variation command is received from the effect control unit 203 (during symbol variation) will be described with reference to the flowchart shown in FIG.
First, the lamp control unit 205 determines whether or not an effect start command (see step S34 shown in FIG. 9) has been received from the effect control unit 203 (see step S51 in FIG. 11). When the determination result is “NO”, the lamp control unit 205 repeats the determination. Then, when an effect start command is received, the determination result in step S51 is “YES”, and the lamp control unit 205 proceeds to step S52.

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

  In step S55, the lamp control unit 205 outputs the lamp data to the lamp 262, and then proceeds to step S56. Accordingly, the lamp 262 is turned on or off based on the lamp data output from the lamp control unit 205. In step S56, the lamp control unit 205 determines whether or not an effect stop command (see step S37 shown in FIG. 9) is received from the effect control unit 203. When the determination result is “NO”, the lamp control unit 205 returns to Step S55 and repeats the processes after Step S55. On the other hand, if the determination result in step S56 is “YES”, that is, if an effect stop command is received from the effect control unit 203, the lamp control unit 205 proceeds to step S57. In step S57, the lamp control unit 205 ends the series of processes after stopping the output of the lamp data.

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

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

  The post-stage unit 20 authenticates whether or not the main control unit 10 is a regular main control unit by using each inspection value obtained from the authentication data received from the main control unit 10 via the effect control unit 203. . Next, the post-stage unit 20 transmits an authentication unsuccessful signal to the effect control unit 203 when the authentication result obtained by the authentication process is unsuccessful. Then, the effect control unit 203 notifies the fact based on the authentication failure signal received from the subsequent stage unit 20. In this way, authentication processing is performed with the latter-stage unit 20 as the authenticator and the main control unit 10 as the person to be authenticated, and the validity of the control command transmitted from the main control unit 10 is authenticated. By this authentication process, the fraudulent act can be detected and fraud to the pachinko gaming machine 1 can be prevented, and the pachinko gaming machine 1 caused by electrical noise or mechanical vibration applied from the outside can be prevented. Malfunctions can also be reduced.

  Hereinafter, processing related to authentication performed between the main control unit 10, the rear stage unit 20, and the peripheral unit will be described. Hereinafter, processing related to authentication between the main control unit 10 and the rear stage unit 20 will be described with reference to the flowcharts shown in FIGS. 12 and 13, but authentication between the main control unit 10 and the prize ball control unit 204 is performed. The processing related to is performed in the same procedure. 12 and 13, when the number of divisions at the time of generating the authentication data is N, the correction data is transmitted after the authentication data is generated and transmitted after the Nth authentication success after the authentication data is transmitted. This shows the processing when doing this.

  FIG. 12 is a flowchart illustrating an example of processing related to authentication by the main control unit 10. The main control unit 10 determines whether it is the correction data transmission timing (step S61). Specifically, the main control unit 10 refers to the correction timing information storage area in the RAM 10c and determines whether or not the value of the correction timing information is zero. When the value of the correction timing information in the RAM 10c is 0, that is, when the correction data is transmitted (step S61: YES), the main control unit 10 calculates a correction value and generates correction data (step S62). Then, the control signal with correction data is transmitted to the rear stage unit 20 through the effect control unit 203 (step S63). And the correction timing information in RAM10c is cleared (step S64), and the process by this flowchart is complete | finished.

  On the other hand, when the value of the correction timing information in the RAM 10c is not 0 at step 61, that is, when it is not the correction data transmission timing (step 61: NO), the main control unit 10 is the authentication data transmission timing. Whether or not (step S62). In the case of the authentication data transmission timing (step S65: YES), the main control unit 10 determines the number of divisions (step S66). The method for determining the number of divisions is arbitrary. The number of divisions may be determined before the transmission timing of authentication data.

  Next, the main control unit 10 divides a predetermined program code by the determined number of divisions, performs a semi-group operation on each of the divided data, and calculates a test value (step S67). On the other hand, an encryption process is performed to generate authentication data (step S68). By this processing, the inspection value and authentication data for the number of divisions are generated. Also, the method of generating the inspection value (such as the type of calculation used for generation) is determined in advance.

  Next, the main control unit 10 sequentially transmits a control signal with authentication data including the generated authentication data to the subsequent stage unit 20 via the effect control unit 203 (step S69). The control command for adding the authentication data is not particularly limited and may be an arbitrary control command. The control signal with authentication data may be transmitted continuously, or may be transmitted by mixing with a normal control signal. The order of transmitting the authentication data is also arbitrary. The main control unit 10 returns to step S69 and continues to transmit the control signal with authentication data until all the authentication data generated in step S68 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. It always returns to step S69 and transmits a control signal with authentication data.

  When all the authentication data is transmitted (step S70: YES), the main control unit 10 determines whether or not the next correction timing is determined (step S71). Whether or not the next correction timing has been determined specifically means whether or not the value of the correction timing information is stored (is not cleared) in the correction timing information storage area in the RAM 10c. . When the value of the correction timing information is stored in the correction timing information storage area in the RAM 10c, that is, when the next correction timing is determined (step S71: YES), the main control unit 10 performs the correction in the RAM 10c. The value of the timing information is decremented by 1 (step S72), and the processing according to this flowchart is terminated.

On the other hand, when the value of the correction timing information is not stored in the correction timing information storage area in the RAM 10c in step S71, that is, when the next correction timing is not determined (step S71: NO), the main control unit 10 determines the correction timing based on the number of divisions (step S73). Specifically, generation and transmission of authentication data for performing authentication processing is performed until the number of successful authentications equals the number of divisions from the next time onward, and generation of correction data for performing correction processing is performed in the next time and As a transmission, the division number is stored in the correction timing information storage area in the RAM 10c, and the processing according to this flowchart is terminated.
In step S65, when it is not the transmission timing of the authentication data (step S65: NO), the main control unit 10 transmits a normal control signal (step S74), and ends the processing according to this flowchart.

  The main control unit 10 may add the authentication data 303 to the control command only when transmitting a predetermined control command to the subsequent stage unit 20. In this case, since the authentication process is performed only when a predetermined control command is transmitted, the rate at which the processing load on the main control unit 10 and the effect control unit 203 increases due to the authentication process can be suppressed. When the predetermined control command is a jackpot command, the jackpot command is transmitted for each round of jackpot, so the authentication process is performed multiple times during a certain period in the jackpot state, improving the accuracy of the authentication process. be able to.

  Also, when the predetermined control command is a jackpot start command or jackpot end command, the jackpot start command or jackpot end command is a control command for starting or ending the jackpot state, and compared with other control commands, the transmission frequency Is low. Therefore, the possibility that 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 latter stage unit 20 will be described. FIG. 13 is a flowchart illustrating an example of processing related to authentication by the rear-stage unit 20. First, the post-stage unit 20 determines whether or not the control signal with authentication data or the control signal with correction data as shown in FIG. 5 transmitted from the main control unit 10 via the effect control unit 203 is received (step). S81). When the determination result is “NO”, the rear stage unit 20 repeats the same determination. When receiving the control signal with authentication data or the control signal with correction data transmitted from the main control unit 10 via the effect control unit 203 (step S81: YES), the rear stage unit 20 proceeds to step S82.

  When the rear stage unit 20 receives the control signal with authentication data or the control signal with correction data (step S81: YES), the rear stage unit 20 determines whether the current timing is the correction timing (step S82). Specifically, the rear stage unit 20 refers to the correction timing information storage area in the RAM 20c and determines whether or not the value of the correction timing information is zero. When the value of the correction timing information in the RAM 20c is 0, that is, in the case of the correction timing (step S82: YES), the correction data 304 is included in the control signal. 304 is subjected to a decoding process to obtain a correction value (step S83), and the correction value is used to correct the expected value stored in advance in the ROM 20b (step S84). And the correction timing information in RAM20c is cleared (step S85), and the process by this flowchart is complete | finished.

  On the other hand, if the value of the correction timing information in the RAM 20c is not 0 in step S82, that is, if the current time is not the correction timing (step S82: NO), the authentication signal 303 is included in the control signal. The unit 20 decrypts the authentication data 303 to obtain a check value (step S86). The rear stage unit 20 stores the acquired inspection value in the inspection value memory (step S87), and performs a semi-group operation (joining process) on all the inspection values in the inspection value memory (step S88). If there is one inspection value in the inspection value memory, the process directly proceeds to step S89 without performing the combining process.

  Then, the post-stage unit 20 collates the operation result (combination result) with the expected value held in advance, and determines whether or not the combined result and the expected value match (step S89). If the combined result matches the expected value (step S89: YES), the rear stage unit 20 generates an authentication result indicating that the authentication with respect to the main control unit 10 was successful (step S90), and the process proceeds to step S94.

  On the other hand, in step S89, when the combined result of the test values and the expected value do not match (step S89: NO), the rear stage unit 20 receives the authentication data 303 of a predetermined number or more (step S91: NO), step S81. Return to and repeat the process. When the authentication data 303 of a predetermined number or more is received (step S91: YES), the rear stage unit 20 makes the authentication to the main control unit 10 unsuccessful (step S92), and proceeds to step S93. 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. Then, the post-stage unit 20 generates an authentication failure signal based on the result of the authentication failure and transmits it to the effect control unit 203 (step S93), and ends the process according to this flowchart.

  If the authentication to the main control unit 10 is successful in step S90, the subsequent stage unit 20 deletes the data in the verification value memory (step S94) and determines whether or not the next correction timing is determined. (Step S95). Whether or not the next correction timing is determined specifically means whether or not a value is stored in the correction timing information storage area in the RAM 20c (is not cleared). When the value of the correction timing information is stored in the RAM 20c, that is, when the next correction timing is determined (step S95: YES), the rear stage unit 20 sets the value of the correction timing information in the RAM 20c to minus 1. In step S96, the process according to this flowchart is terminated.

  On the other hand, when the value of the correction timing information is not stored in the RAM 20c in step S95, that is, when the next correction timing is not determined (step S95: NO), the correction is made based on the rear stage unit 20 and the number of connections. Timing is determined (step S97). Specifically, until the number of successful authentications is equal to the number of connections after the next time, the received data is subjected to a combining process, and the next time, the expected value stored in the ROM 20b using the received data. In order to perform correction processing on the image data, the number of couplings is stored in the correction timing information storage area in the RAM 20c, and the processing according to this flowchart ends.

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

  Further, since authentication processing such as decryption of authentication data and collation between the inspection value and the expected value is executed only by the rear-stage unit 20, the processing load on the CPU 203a constituting the effect control unit 203 does not increase. For this reason, it is possible to prevent problems such as a reduction in the processing speed of the effect control unit 203 and a smooth display for the effect.

  Next, processing related to authentication by the effect control unit 203 will be described. FIG. 14 is a flowchart illustrating an example of processing related to authentication by the effect control unit 203. First, the effect control unit 203 determines whether or not a control signal has been received from the main control unit 10 (step S101). When the determination result is “NO”, the effect control unit 203 repeats the determination. And if a control signal is received from the main control part 10, the judgment result of step S101 will be "YES", and the production | presentation control part 203 will progress to step S102.

  In step S102, the effect control unit 203 determines whether the received control signal includes the authentication data 303 or the correction data 304. When the determination result in step S102 is “NO”, that is, when the authentication data 303 or the correction data 304 is not included in the received control signal, the effect control unit 203 performs the control included in the normal control signal 300. Processing based on the command data 301 and the accompanying data 302 is performed (step S107), and the processing according to this flowchart is terminated.

  On the other hand, when the authentication data 303 or the correction data 304 is included in the control signal received by the effect control unit 203 (step S102: YES), the effect control unit 203 proceeds to step S103. Here, whether or not the authentication data 303 or the correction data 304 is included in the control signal is determined by, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, Whether to determine whether any bit constituting the data 301 or the accompanying data 302 or separately provided identification data (not shown) indicates that the authentication data 303 or the correction data 304 is included Alternatively, it may be determined whether or not the control command data 301 included in the control signal 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 transmits the received control signal with authentication data or control signal with correction data to the subsequent unit 20 as it is, and then starts processing based on the control command data 301 and the accompanying data 302 (step S103). S104), the process proceeds to step S105.

  In step S <b> 105, the effect control unit 203 determines whether an authentication unsuccessful signal transmitted from the subsequent unit 20 has been received. When the authentication unsuccessful signal has not been received from the rear stage unit 20 (step S105: NO), the effect control unit 203 determines that the main control unit 10 has been successfully authenticated in the rear stage unit 20, and the processing according to this flowchart. Exit.

  On the other hand, when the authentication failure signal is received from the rear stage unit 20 (step 105: YES), the effect control unit 203 determines that the main stage control unit 10 has not been successfully authenticated in the rear stage unit 20, and step S104. The center based on the control command data 301 and the accompanying data 302 started in the above process is interrupted, and a notification signal for notifying an illegal act is managed by the symbol display unit 104, the lamp control unit 205, or the pachinko gaming machine 21 After transmitting to the control device or the like (step S106), the processing according to this flowchart is terminated.

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

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

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

  In the flowchart of FIG. 14, the effect control unit 203 determines whether the control signal transmitted from the main control unit 10 is a normal control signal, a control signal with authentication data, or a control signal with correction data. However, without making the same determination, it may be transmitted to the subsequent stage unit 20 as it is regardless of the type of the received control signal. Specifically, the effect control unit 203 does not determine whether or not the authentication data 303 or the correction data 304 is included in the received control signal, and transmits it directly to the subsequent stage unit 20 as well as the control command data 301 and Processing based on the accompanying data 302 is started. In this case, the post-stage unit 20 determines whether or not the authentication data 303 or the correction data 304 is included in the received control signal. If not, the combining process or the correction process is not started, the received control command data 301 and the accompanying data 302 are discarded, and the process related to the authentication of the rear stage unit 20 is ended.

  Next, a specific example of the correction timing of the correction process for the expected value among the processes shown in FIGS. 12 and 13 will be described. FIG. 15 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the succeeding unit 20 (authenticated person). In FIG. 15, as in FIGS. 12 and 13, when the number of divisions at the time of generating authentication data is N, the correction is performed after the authentication data is generated and transmitted after the Nth successful authentication after transmitting the authentication data. The process in the case of transmitting data is shown. In the first embodiment, the post-stage unit 20 receives the authentication data transmitted by the main control unit 10 via the peripheral unit 30 (the effect control unit 203). However, in the sequence diagram of FIG. Therefore, the description of the processing of the peripheral part 30 is omitted.

  First, the main control unit 10 proceeds to the process of step S111, determines the number of divisions used for the current authentication process by an arbitrary method, and then proceeds to step S112. For example, the main control unit 10 determines that the current number of divisions is two. In step S112, the main control unit 10 divides the predetermined program code stored in advance in the storage area of the ROM 10b into two blocks (storage areas), and uses the program code stored in each block, An inspection value is calculated, and further encryption processing is performed to generate two authentication data (step S112). Then, two control signals with authentication data including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S113).

  Thereafter, since there is no value (cleared) in the correction timing information storage area in the RAM 10c, the main control unit 10 determines the correction data transmission timing based on the number of divisions (step S114). In this case, since the number of divisions is 2, after the transmission of the control signal with authentication data this time, the authentication data for performing the authentication process is generated and transmitted until the next successful authentication is performed up to 2 times. It is assumed that the correction data for performing the correction process is generated and transmitted at the time of. That is, correction timing information = 2.

  Next, processing in the rear stage unit 20 will be described. The rear stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S115). Then, the authentication data in the control signal with authentication data is subjected to a decryption process to obtain an inspection value, and a combination process is performed (step S116). When the combined result matches the expected value in the ROM 20b, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 has been successful (step S117). In this case, when the joining process is performed using two inspection values, it should match the expected value (number of joins = 2).

  Thereafter, since the correction timing information has no value (cleared), the subsequent stage unit 20 determines the correction timing of the expected value based on the number of connections (step S118). In this case, since the number of connections is 2, after the current authentication process, the next time or later, the number of successful authentications is up to 2 times, and the received data is combined, and the next time, the received data is used. It is assumed that correction processing is performed on the expected value stored in the ROM 20b. That is, correction timing information = 2.

  Turning to the description of the second authentication process, the main control unit 10 again determines the number of divisions by an arbitrary method. For example, if the current number of divisions = 5 (step S119), the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into five blocks (storage areas). The five test values are calculated using the program code stored in, and further subjected to encryption processing to generate five authentication data (step S120). Then, five control signals with authentication data including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S121). When the transmission of the authentication data is completed, the main control unit 201 sets the correction timing information to 1 (2-1 = 1).

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S122), and decrypts the authentication data in the control signal with authentication data. The inspection value is obtained by performing the combining process (step S123). When the combined result matches the expected value, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 has been successful (step S124). When the authentication is successful, the rear stage unit 20 sets the correction timing information to 1 (2-1 = 1).

  Turning to the description of the third authentication process, the main control unit 10 again determines the number of divisions by an arbitrary method. For example, if the current number of divisions = 3 (step S125), the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into three blocks (storage areas), and each block Are used to calculate three test values and further perform encryption processing to generate three authentication data (step S126). Then, three control signals with authentication data including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S127). When the transmission of the authentication data is completed, the main control unit 10 sets the correction timing information to 0 (1-1 = 0).

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S128), and decrypts the authentication data in the control signal with authentication data. The inspection value is obtained by performing the combining process (step S129). If the combined result matches the expected value, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 was successful (step S130). When the authentication is successful, the rear stage unit 20 sets the correction timing information to 0 (1-0 = 0).

  In this way, after the first authentication process, when the second authentication process is successful, the main control unit 10 generates correction data because the correction timing information = 0 (step S131), and the subsequent stage unit 20 Then, the control signal with correction data is transmitted via the effect control unit 203 (step S132). It should be noted that the control signal with correction data and the control signal with authentication data cannot be distinguished apparently. Thereafter, the main control unit 10 clears the correction timing information (step S133).

  When the rear stage unit 20 receives the control signal with correction data transmitted from the main control unit 10 via the effect control unit 203 (step S134), since the correction timing information = 0, the correction included in the received control signal. Correction processing is performed using the data, and the expected value is corrected (step S135). Thereafter, the rear stage unit 20 clears the correction timing information (step S136).

  Turning to the description of the fourth authentication process, the main control unit 10 again determines the number of divisions by an arbitrary method. For example, if the current number of divisions = 6 (step S137), the main control unit 10 divides a predetermined program code stored in advance in the storage area of the ROM 10b into six blocks (storage areas). 6 are calculated using the program code stored in, and further subjected to encryption processing to generate 6 authentication data (step S138). Then, six control data-added control signals including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S139).

  Thereafter, since the correction timing information has no value (cleared), the main control unit 10 determines the correction data transmission timing based on the division number (step S140). In this case, since the number of divisions is 6, after the transmission of the control signal with authentication data this time, the authentication data for performing the authentication processing is generated and transmitted until the next successful authentication up to 6 times. It is assumed that the correction data for performing the correction process is generated and transmitted at the time of. That is, correction timing information = 6.

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S141), and decrypts the authentication data in the control signal with authentication data. The inspection value is obtained by performing the combining process (step S142). If the combined result matches the expected value, the subsequent stage unit 20 determines that the authentication with respect to the main control unit 10 was successful (step S143).

  After that, since the correction timing information has no value (cleared), the subsequent stage unit 20 determines the correction timing of the expected value based on the number of connections (step S144). In this case, since the number of connections is 6, after the current authentication process, the next time or later, the number of successful authentications is 6 for the received data, and the next time, using the received data. It is assumed that correction processing is performed on the expected value stored in the ROM 20b. That is, correction timing information = 6.

  As described above, in the first embodiment, the main control unit 10 transmits the correction data at a timing based on the number of divisions obtained by dividing the predetermined data, and the subsequent unit 20 receives the authentication for the main control unit. The expected value is corrected at a timing based on the number of authentication data (number of connections) that is the target of the binary operation. Since the number of divisions and the number of combinations are values known only by the main control unit 10 and the subsequent stage unit 20, the fraudulent person cannot know the transmission timing of the correction data used for correcting the expected value. As a result, the expected value held by the rear stage unit 20 can be corrected without being known to the fraudulent person, the fraudulent action and the malfunction of the gaming machine can be detected, and the fraudulent control command caused by these can be detected. Execution can be prevented.

  In the first embodiment, the test value generation method is configured to set a specific half-group operation in advance. However, the present invention is not limited to this. For example, based on the current number of divisions, a plurality of half-group calculations are performed. It may be configured to select one half-group operation used for generating the next inspection value from the group operation. Specifically, for example, when the current division number is an odd number, the main control unit 10 selects the next half group calculation different from the currently used half group calculation, and when the current division number is an even number, The next half group calculation is the same as the half group calculation used this time. Note that the first half-group operation is set in advance to use the same method between the main control unit 10 and the subsequent stage unit 20. In this case, since the number of divisions and the number of connections are values known only by the main control unit 10 and the subsequent stage unit 20, the fraudulent person 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 inspection value generation method based on the number of divisions.

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

  Further, the authentication data 303 may be generated including the control command data 301 and the accompanying data 302 transmitted this time. 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.

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

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

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

(A) Since the program becomes complicated, it becomes difficult to maintain consistency with other functions (in this case, an unexpected error may occur).
(B) Although the authentication process can be made common even if the model of the pachinko gaming machine 1 is different, the production process is often different for each model of the pachinko gaming machine 1. Therefore, it is necessary to design the entire program of the processing executed by the effect control unit 203 including the authentication processing that can be shared for each model of the pachinko gaming machine 1, and the design takes a lot of time and the work efficiency is improved. bad.
(C) When changing the authentication algorithm for authentication, the process in the peripheral part 30 which performs a predetermined process must be changed. Due to this change, it takes a lot of time and labor to verify whether or not the desired authentication function can be obtained, and there is a problem that it takes a lot of time and effort to develop a gaming machine. It cannot be changed easily.

  Further, when the authentication data 303 is added only to a predetermined control command, it is only necessary to add an authentication process related to the predetermined control command to the program executed by the effect control unit 203. 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 back | latter stage part 20 is provided in the back | latter stage of the production | presentation control part 203, the difference of the processing capability between CPU10a which comprises the main control part 10, and CPU203a which comprises the production | generation control part 203 In addition, a difference in storage capacity between the ROM 10 b constituting the main control unit 10 and the ROM 203 b constituting the effect control unit 203 can be absorbed by the rear stage unit 20. Thereby, despite the difference in processing capacity and storage capacity between the main control unit 10 and the effect control unit 203, the security level between the main control unit 10 and the effect control unit 203 can be maintained. it can.

  For example, the processing capacity of the CPU 10 a constituting the main control unit 10 and the storage capacity of the ROM 10 b constituting the main control unit 10 are the processing capacity of the CPU 203 a constituting the effect control unit 203 and the storage capacity of the ROM 203 b constituting the effect control unit 203. When there is a margin in comparison, the main control unit 10 transmits the authentication data 303 obtained by performing a complicated or advanced encryption process to each inspection value to the subsequent stage unit 20, and the subsequent stage unit 20 receives the above-mentioned An authentication success signal or an authentication failure signal (obtained by applying a relatively simple or low-level encryption process to the authentication result obtained by authenticating the main control unit 10 using each inspection value obtained from the authentication data 303 ( Hereinafter, the authentication success signal or the like) is transmitted to the effect control unit 203. Then, the production control unit 203 performs processing according to the authentication result obtained from the authentication success signal or the like. By configuring in this way, even if a complicated or advanced authentication method is not used, if an authentication process using a relatively simple authentication method is performed, the main control unit 10 and the latter part 20 and the latter part A high security level can be maintained between 20 and the effect control unit 203.

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

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

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

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

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

  For example, every time one inspection value is generated, the main control unit 10 determines the amount of data used for the generation. In this case, the main control unit 10 repeats the determination of the data amount and the generation of the test value until the generation of the test value using all the program codes in the predetermined area of the ROM 10b is completed. For this reason, in the second embodiment, how many inspection values are generated (that is, how many divisions are to be made) depends on the generation of inspection values using all program codes in a predetermined area of the ROM 10b. I do not know until completion.

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

(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. 16 is a flowchart illustrating an example of processing related to authentication by the main control unit. In this flowchart, a process for determining the amount of data every time an inspection value is generated will be described. In FIG. 16, when the number of data blocks obtained by dividing a predetermined program code at the time of test value generation, that is, the number of divisions is N, after the Nth successful authentication after transmission of the authentication data, The process in the case of transmitting correction data after generating and transmitting is shown.

  First, the main control unit 10 determines whether or not it is the correction data transmission timing (step S151). Specifically, the main control unit 10 refers to the correction timing information storage area in the RAM 10c and determines whether or not the value of the correction timing information is zero. When the value of the correction timing information in the RAM 10c is 0, that is, when the correction data is transmitted (step S151: YES), the main control unit 10 calculates the correction value and generates the correction data (step S152). Then, the control signal with correction data is transmitted to the rear stage unit 20 through the effect control unit 203 (step S153). And the correction timing information in RAM10c is cleared (step S154), and the process by this flowchart is complete | finished.

  On the other hand, if the value of the correction timing information in the RAM 10c is not 0 in step S151, that is, if it is not the correction data transmission timing (step 151: NO), the main control unit 10 is the authentication data transmission timing. Whether or not (step S152). In the case of the transmission timing of authentication data (step S155: YES), the main control unit 10 determines the amount of data used for dividing a predetermined program code when generating a test value (step S156). The method for determining the data amount is arbitrary. Further, the data amount may be determined before the transmission timing of the authentication data.

  Next, the main control unit 10 reads out the program code having the data amount determined in step S156, for example, from the top of the program code storage area 400 in the ROM 10b, and performs a semi-group operation to calculate a test value (step S157). ), Authentication data is generated by performing an encryption process on the inspection value (step S158). Also, the method of generating the inspection value (such as the type of calculation used for generation) is determined in advance.

  Subsequently, the main control unit 10 transmits a control signal with authentication data including the generated authentication data to the rear stage unit 20 via the effect control unit 203 (step S159). Until the inspection value is generated using all the program codes in the program code storage area 400 (step S160: 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 S156, 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 test values, for example, the main control unit 10 sets the program code written in the area next to the program code used for the previous test value generation by the data amount determined in step S156. Read to generate inspection value. Note that when the final test value is generated, the data amount determined in step S156 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 S160: 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.

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

  Next, the main control unit 10 determines whether or not the next correction timing has been determined (step S161). Whether or not the next correction timing has been determined specifically means whether or not the value of the correction timing information is stored (is not cleared) in the correction timing information storage area in the RAM 10c. . When the value of the correction timing information is stored in the correction timing information storage area in the RAM 10c, that is, when the next correction timing is determined (step S161: YES), the main control unit 10 performs the correction in the RAM 10c. The value of the timing information is decremented by 1 (step S162), and the processing according to this flowchart ends.

On the other hand, when the value of the correction timing information is not stored in the correction timing information storage area in the RAM 10c in step S161, that is, when the next correction timing is not determined (step S161: NO), the main control unit 10 determines the correction timing based on the number of divisions (step S163). Specifically, generation and transmission of authentication data for performing authentication processing is performed until the number of successful authentications equals the number of divisions from the next time onward, and generation of correction data for performing correction processing is performed in the next time and As a transmission, the division number is stored in the correction timing information storage area in the RAM 10c, and the processing according to this flowchart is terminated.
In step S155, when it is not the transmission timing of the authentication data (step S155: NO), the main control unit 10 transmits a normal control signal (step S164), and ends the process according to this flowchart.

  Processing related to authentication in the rear stage unit 20 and the effect control unit 203 is the same as that in the first embodiment. The post-stage unit 20 extracts authentication data from the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203, performs authentication processing using the authentication data, and performs authentication processing when authentication is unsuccessful. A success signal is generated and transmitted to the effect control unit 203. When the expected value needs to be changed, the correction data is extracted from the control signal with correction data transmitted via the effect control unit 203, and correction processing is performed using the correction data. When the production control unit 203 receives an authentication failure signal from the rear stage unit 20, the production control unit 203 interrupts the processing based on the control command and transmits a notification signal.

  Next, a specific example of the correction timing of the correction process for the expected value among the processes shown in FIGS. 16 and 13 will be described. FIG. 17 is a processing sequence illustrating an example of a mutual relationship between processes executed by the main control unit 10 (authenticated person) and the succeeding unit 20 (authenticated person). In FIG. 17, for convenience of explanation, the amount of data used to generate the inspection value is collectively determined. However, as shown in the flowchart of FIG. 16, the amount of data is determined every time the inspection value is generated. May be. In FIG. 17, as in FIGS. 16 and 13, when the number of data blocks obtained by dividing a predetermined program code at the time of test value generation, that is, when the number of divisions is N, N The process in the case of transmitting correction data after generating and transmitting authentication data after successful authentication for the second time is shown. In the second embodiment, the post-stage unit 20 receives the authentication data transmitted by the main control unit 10 via the peripheral unit 30 (the effect control unit 203). However, in the sequence diagram of FIG. Therefore, the description of the processing of the peripheral part 30 is omitted.

  First, the main control unit 10 proceeds to the process of step S171, and determines the data amount in the current authentication process by an arbitrary method. For example, if the total data amount is 12 bytes and the data amount used to generate the inspection value is 7 bytes and 5 bytes, respectively, two inspection values are generated, and the number of divisions = 2 (step S171). . In step S172, the main control unit 10 reads out 7-byte and 5-byte data in order from the top of the program code storage area 400 of the ROM 10b in which a predetermined program code is stored in advance. An inspection value is calculated, and further encryption processing is performed to generate two authentication data (step S172). Then, two control signals with authentication data including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S173).

  Thereafter, since there is no value (cleared) in the correction timing information storage area in the RAM 10c, the main control unit 10 determines the correction data transmission timing based on the number of divisions (step S174). In this case, since the number of divisions is 2, after the transmission of the control signal with authentication data this time, the authentication data for performing the authentication process is generated and transmitted until the next successful authentication is performed up to 2 times. It is assumed that the correction data for performing the correction process is generated and transmitted at the time of. That is, correction timing information = 2.

  Next, processing in the rear stage unit 20 will be described. The rear stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S175). Then, the authentication data in the control signal with authentication data is subjected to a decryption process to obtain an inspection value, and a combination process is performed (step S176). When the combined result matches the expected value in the ROM 20b, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 has been successful (step S177). In this case, when the joining process is performed using two inspection values, it should match the expected value (number of joins = 2).

  After that, since the correction timing information has no value (cleared), the subsequent stage unit 20 determines the correction timing of the expected value based on the number of connections (step S178). In this case, since the number of connections is 2, after the current authentication process, the next time or later, the number of successful authentications is up to 2 times, and the received data is combined, and the next time, the received data is used. It is assumed that correction processing is performed on the expected value stored in the ROM 20b. That is, correction timing information = 2.

  Turning to the description of the second authentication process, the main control unit 10 again determines the data amount in the current authentication process by an arbitrary method. For example, if the amount of data used to generate the inspection value is 2 bytes, 3 bytes, 2 bytes, 3 bytes, and 2 bytes, respectively, 5 inspection values are generated, and the number of divisions is 5 (step S179). ). The main control unit 10 reads data of 2 bytes, 3 bytes, 2 bytes, 3 bytes, and 2 bytes in order from the top of the program code storage area 400, calculates five inspection values using the respective data, and further performs encryption. The authentication process is performed to generate five authentication data (step S180). Then, five control signals with authentication data including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S181). When the transmission of the authentication data is completed, the main control unit 201 sets the correction timing information to 1 (2-1 = 1).

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S182), and decrypts the authentication data in the control signal with authentication data. The inspection value is obtained by performing the combining process (step S183). If the combined result matches the expected value, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 was successful (step S184). When the authentication is successful, the rear stage unit 20 sets the correction timing information to 1 (2-1 = 1).

  Turning to the description of the third authentication process, the main control unit 10 again determines the amount of data in the current authentication process by an arbitrary method. For example, if the data amount used to generate the inspection value is 3 bytes, 4 bytes, and 5 bytes, respectively, three inspection values are generated, and the number of divisions = 3 (step S185). The main control unit 10 reads out 3 bytes, 4 bytes, and 5 bytes of data in order from the top of the program code storage area 400, calculates three test values using the respective data, and performs encryption processing 3 Two pieces of authentication data are generated (step S186). Then, three control data-added control signals including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S187). When the transmission of the authentication data is completed, the main control unit 10 sets the correction timing information to 0 (1-1 = 0).

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S188), and decrypts the authentication data in the control signal with authentication data. The inspection value is obtained by performing the combining process (step S189). If the combined result matches the expected value, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 was successful (step S190). When the authentication is successful, the rear stage unit 20 sets the correction timing information to 0 (1-0 = 0).

  As described above, after the first authentication process, when the second authentication process is successful, the main control unit 10 generates correction data because the correction timing information = 0 (step S191), and the subsequent stage unit 20 receives the correction data. Then, the control signal with correction data is transmitted via the effect control unit 203 (step S192). It should be noted that the control signal with correction data and the control signal with authentication data cannot be distinguished apparently. Thereafter, the main control unit 10 clears the correction timing information (step S193).

  When the rear stage unit 20 receives the control signal with correction data transmitted from the main control unit 10 via the effect control unit 203 (step S194), since the correction timing information = 0, the correction included in the received control signal. A correction process is performed using the data to correct the expected value (step S195). Thereafter, the rear stage unit 20 clears the correction timing information (step S196).

  Turning to the description of the fourth authentication process, the main control unit 10 again determines the data amount in the current authentication process by an arbitrary method. For example, if the amount of data used to generate inspection values is 2 bytes, 2 bytes, 2 bytes, 2 bytes, 2 bytes, and 2 bytes, respectively, 6 inspection values are generated, and the number of divisions is 6. (Step S197). The main control unit 10 reads data of 2 bytes, 2 bytes, 2 bytes, 2 bytes, 2 bytes, and 2 bytes in order from the top of the program code storage area 400, and calculates six test values using each data. Further, encryption processing is performed to generate six authentication data (step S198). Then, six control data-added control signals including the respective authentication data are transmitted to the rear stage unit 20 via the effect control unit 203 (step S199).

  Thereafter, the main control unit 10 determines the transmission timing of the correction data based on the number of divisions because the correction timing information has no value (cleared) (step S200). In this case, since the number of divisions is 6, after the transmission of the control signal with authentication data this time, the authentication data for performing the authentication processing is generated and transmitted until the next successful authentication up to 6 times. It is assumed that the correction data for performing the correction process is generated and transmitted at the time of. That is, correction timing information = 6.

  Subsequently, the post-stage unit 20 receives the control signal with authentication data transmitted from the main control unit 10 via the effect control unit 203 (step S201), and decrypts the authentication data in the control signal with authentication data. The inspection value is obtained to perform the combining process (step S202). When the combined result matches the expected value, the rear stage unit 20 determines that the authentication with respect to the main control unit 10 is successful (step S203).

  Thereafter, since the correction timing information has no value (cleared), the subsequent stage unit 20 determines the correction timing of the expected value based on the number of connections (step S204). In this case, since the number of connections is 6, after the current authentication process, the next time or later, the number of successful authentications is 6 for the received data, and the next time, using the received data. It is assumed that correction processing is performed on the expected value stored in the ROM 20b. That is, correction timing information = 6.

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

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

  However, in the above case, since one CPU has the functions of two CPUs, the processing load generally increases. Therefore, for example, it is conceivable to perform the processing of the rear stage unit 20 with a dual CPU configuration.

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

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

[1] Since the production control unit and the rear stage unit can be designed and developed at the same time, the product development period can be shortened compared to the case where parallel development is impossible.
[2] Since it is possible to take independent development systems for the production control unit and the latter part, confidential business information (for example, an authentication processing method, etc.) when performing design and manufacturing verification of the production control unit and the latter part , Processing related to games, etc.) can be reduced out of the respective development system.

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

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

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

4). Ease of change of authentication method When changing the authentication method or upgrading the authentication algorithm, it is sufficient to change or upgrade only the main control unit and the latter part, and change the processing related to the authentication of the production control unit. You don't have to.

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

6). Reducing the processing load of the production control unit When the authentication function to be implemented in the latter stage unit is implemented with the software of the production control unit, the processing load on the production control unit increases by adding an authentication function to the existing game processing of the production control unit Will do. Therefore, it is conceivable to use a dual core CPU as the CPU constituting the production control unit. Since the processing load for realizing the authentication process can be distributed by using the dual core CPU, the authentication function is provided so as not to affect the existing game process of the production control unit as much as possible. The authentication function can be easily realized.
