The present invention relates to an authentication method and an authentication program to be performed.

Among fraudulent acts that are performed on gaming machines and forcibly pay out game media such as medals and game balls regardless of the game, the main control board on which the main control unit is mounted and the periphery on which the peripheral unit is mounted The following are related to the substrate.
(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) ROM replacement as described in (2) above, with an illegal board (spoofing board) provided between the main control board and the peripheral board

  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 machines include a main control board and a peripheral board that performs a predetermined process based on a control command transmitted by the main control board. In this pachinko machine, the main control board is authenticated to authenticate the main control board when the control command transmitted to the peripheral board is a jackpot reach command for causing the peripheral board to execute the process of reaching the jackpot. Data is added to a predetermined jackpot reach command and transmitted to the peripheral board. When the peripheral board receives the jackpot reach command, the peripheral board authenticates the main control board based on the authentication data transmitted in addition to the jackpot reach 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 2008-279039 A

  In the first conventional example described above, the CPU mounted on the first peripheral board 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, and displays The CPU mounted on the second peripheral board that controls the CPU 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 appears particularly when changing the model of a gaming machine. Furthermore, with the recent diversification of the effects of gaming machines, the code size of the program to be executed by the CPU tends to become enormous, so that the above-mentioned problems are further increased by adding an 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 are inconveniences such as the authentication process itself being unable to be added. 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 at the time of reach or jackpot. Therefore, the possibility that the above-described inconvenience occurs increases.

  In the above-described first conventional example, only one CPU constituting the peripheral part performs one-step authentication processing (ID addition processing). Furthermore, as described above, since the processing load of the CPU configuring the peripheral portion increases by causing the CPU configuring the peripheral portion to execute authentication processing in addition to the existing processing, the CPU configuring the peripheral portion includes: In order to further enhance security, it is difficult to execute authentication processing by a more complicated calculation or multi-step authentication processing than ever before.

  On the other hand, in the second conventional example described above, 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 changes the first key. The first key data is changed at a predetermined timing by the means. 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. 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 described above, both the CPU constituting the main control unit and the CPU constituting the peripheral part increase the processing load, so that the processing speed decreases and the basic processing and the progress of the game content There is a risk that the original process of effect processing may not be performed smoothly.

In the third conventional example, as in the first conventional example, in the case where the CPU on the peripheral board executes the authentication process in addition to the existing game process, the authentication data is added to the jackpot reach command. Even if it is transmitted to the peripheral board, the processing load of the CPU on the peripheral board increases, so the processing speed decreases, display for presentation is not performed smoothly, or it is difficult to add the authentication process itself. It is conceivable that a design constraint occurs. 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 board (image control board) that performs various presentation controls.
Furthermore, if there is a difference in processing capacity between the main control board and the peripheral board, it is necessary to realize an authentication function in accordance with a board with a low processing capacity, etc., in order to realize such an authentication function. There is a strong demand for gaming machines that eliminate the restrictions. In addition, there is a strong demand for the development of a gaming machine that does not require major modifications to the program processing function of the conventional peripheral board when the function of the authentication system is improved.

  Furthermore, as described above, the CPU constituting the peripheral board increases the processing load and the program capacity of the CPU constituting the peripheral board by causing the CPU constituting the peripheral board to execute the authentication process in addition to the existing process. In order to further enhance security, it is difficult to execute an authentication process or a multi-stage authentication process with more complicated operations than ever before.

  By the way, a gaming machine may malfunction when external electrical noise or mechanical vibration is applied. For example, when noise such as electromagnetic waves or static electricity is added from outside the gaming machine when a control command is transmitted from the main control unit to the peripheral part, a bit error occurs in the control command data due to the influence of this noise, Control commands may be changed. In this case, if the control command that should originally be transmitted to the peripheral part is a control command other than the jackpot command but the bit error occurs and the control command is changed to the jackpot command, the above-described fraud Even if the game is not performed, an unreasonable amount of game media (for example, game balls and medals) is paid out to the player, and the game hall suffers a great deal of damage. However, in the first and second conventional examples described above, since no countermeasure is taken for such a situation, the inconvenience that the game hall suffers a great deal of damage cannot be solved.

  The present invention has been made in view of the above-described circumstances, and an example is to solve the above-described problems. A gaming machine, an authentication method, and a game machine that can solve these problems The purpose is to provide an authentication program.

  In order to solve the above-described problem, a gaming machine according to the first aspect of the present invention includes a main control unit that outputs a control command, an intermediate unit that performs intermediate processing for converting data added to the control command, and A peripheral unit that performs predetermined processing based on a control command, and the main control unit, when the control command is a jackpot reach command for causing the peripheral unit to execute a process of reaching the jackpot reach state The authentication data for authenticating the main control unit or data converted from the authentication data is added to the jackpot reach command and supplied to the intermediate unit, and the intermediate unit is added to the jackpot reach command The intermediate processing is performed on the authentication data or the converted data, and the intermediate processing information obtained by the intermediate processing is changed to the jackpot Lee. It is added to the command and supplied to the peripheral unit, and the peripheral unit authenticates the main control unit using the intermediate processing information added to the jackpot reach command, and processes according to the obtained authentication result It is characterized by performing.

  The invention according to claim 2 relates to the gaming machine according to claim 1, wherein the main control unit includes storage means in which a predetermined program code is stored, and the predetermined program code is used to It is characterized by generating authentication data.

  The invention according to claim 3 relates to the gaming machine according to claim 2, wherein the main control unit generates the authentication data using the predetermined program code and the jackpot reach command. It is said.

  Further, the invention according to claim 4 relates to the gaming machine according to any one of claims 1 to 3, wherein the peripheral unit, when the authentication result indicates an unsuccessful authentication of the main control unit, It is characterized by outputting a notification signal to notify that effect.

  An authentication method according to the invention of claim 5 is based on a main control unit that outputs a control command, an intermediate unit that performs an intermediate process for converting data added to the control command, and the control command. An authentication method used in a gaming machine including a peripheral unit that performs a predetermined process, and when the control command is a jackpot reach command for causing the peripheral unit to perform a process of a jackpot reach state, A first step in which the main control unit adds authentication data for authenticating the main control unit or data converted from the authentication data to the jackpot reach command and supplies it to the intermediate unit; and The intermediate processing is performed on the authentication data or the converted data added to the jackpot reach command and obtained by the intermediate processing. A second step of adding the processed intermediate processing information to the jackpot reach command and supplying the same to the peripheral portion, and the peripheral section using the intermediate processing information added to the jackpot reach command to the main control section And a third step of performing processing according to the obtained authentication result.

  The invention according to claim 6 relates to the authentication method according to claim 5, wherein the main control unit includes storage means in which a predetermined program code is stored, and in the first step, the predetermined The authentication data is generated using the program code.

  The invention according to claim 7 relates to the authentication method according to claim 6, wherein, in the first step, the main control unit uses the predetermined program code and the jackpot reach command to perform the authentication. It is characterized by generating data.

  The invention according to claim 8 relates to the authentication method according to any one of claims 5 to 7, and in the third step, the peripheral unit is configured such that the authentication result is not authenticated by the main control unit. When it indicates success, it is characterized in that a notification signal for notifying that is output.

  An authentication program according to the invention described in claim 9 causes a computer to realize the function described in any of claims 5 to 8.

  According to the present invention, the regular main control board on which the main control unit is mounted is replaced with an unauthorized main control board, the ROM that stores the normal program executed by the CPU mounted on the main control board, and the program For example, replacement with a ROM that stores an unauthorized program that has been altered, or replacement of the ROM after providing an unauthorized substrate (spoofing substrate) between the main control board and the peripheral board on which the peripheral portion is mounted. It can detect fraud. In addition, according to the present invention, it is possible to reduce malfunction of the gaming machine due to electrical noise or mechanical vibration applied from the outside.

  According to the present invention, the intermediate unit performs the intermediate processing for converting the authentication data added to the control command or the data converted from the authentication data, and the peripheral unit stores the intermediate processing information added to the control command. Since the main control unit is used to authenticate, in addition to the malfunction of the gaming machine due to the above-mentioned fraudulent act against the main control unit and noise, etc. It is possible to prevent the malfunction of the gaming machine due to the above, and to improve the security.

  Further, since authentication data or data converted from this authentication data is added only to the jackpot reach command, it is only necessary to add an authentication process related to the jackpot reach command to the program executed by the peripheral portion. Therefore, since it is not necessary to design a new timing for the entire program executed by the peripheral portion, the authentication function is compared with the case where authentication data or data converted from this authentication data is added to all control commands. Designing the timing to add, implementing the function, and verifying the function can be achieved more easily and with fewer man-hours.

  Further, according to the present invention, the configuration of the authentication program and the predetermined processing program becomes relatively simple, so that it is easy to maintain consistency with other functions. In addition, even if the predetermined processing differs for each gaming machine model, the authentication process can be shared, so that the program design for each gaming machine model is easy and the design time can be shortened. Work efficiency.

  Further, according to the present invention, when the control command transmitted from the main control unit is a jackpot reach command, authentication data or data converted from the authentication data is added to the control command, so that the authentication data is transmitted alone. Compared to the case, an increase in communication load between the main control unit and the peripheral unit can be suppressed. Moreover, compared with the case where it transmits by authentication data single-piece | unit, the risk that authentication data will be extracted from communication data and analyzed can be reduced.

  Furthermore, according to the present invention, since the intermediate part is provided between the main control part and the peripheral part, there is a difference in processing capability between the CPU constituting the main control part and the CPU constituting the peripheral part. Even if there is a difference in capacity between the ROM configuring the main control unit and the ROM configuring the peripheral unit, the difference can be absorbed in the intermediate unit. For example, when the processing capacity of the CPU that constitutes the main control unit has a margin as compared with the processing capacity of the CPU that constitutes the peripheral part, the main control unit converts the data obtained by converting authentication data in a complicated or advanced manner into an intermediate part. The intermediate unit supplies data obtained by converting the received data by a relatively simple method to the peripheral unit. In addition, when the capacity of the ROM constituting the peripheral portion is larger than the capacity of the ROM constituting the main control unit, the main control unit can convert the authentication data as it is or using a relatively simple method to convert the intermediate data The intermediate unit supplies data obtained by converting the received data by a complicated or advanced technique to the peripheral unit. This is not only the case where there is a difference in the processing capacity and ROM capacity of the CPUs that respectively constitute the main control unit and the peripheral unit, but there is no difference between these, but the CPU or the peripheral that constitutes the main control unit The same applies to the case where all or a part of one of the programs executed by the CPUs constituting the unit is changed (version upgrade or the like), or when a formal difference occurs in the format of the authentication data.

  Further, according to the present invention, the jackpot reach is generated more frequently than the jackpot. Moreover, the occurrence timing of jackpot reach has randomness. Accordingly, by performing the authentication process when transmitting the jackpot reach command, 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, since the authentication process is performed only when the jackpot reach command is transmitted, the rate at which the processing load of the main control unit increases due to the authentication process can be suppressed.

  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 main control unit 201, the intermediate unit 202, the sub control unit 203, the prize ball control unit 204, and the lamp control unit 205 configured as described above are different printed circuit boards (main control board, intermediate board, sub control board, (Prize ball control board, lamp control board) Among these, “peripheral board” is used as a general term for the intermediate board, the sub control board, the prize ball control board, and the lamp control board. For example, the prize ball control unit 204 can be mounted on the same printed circuit board as the main control unit 201. Further, the intermediate unit 202 can be mounted on the same printed circuit board as the sub-control unit 203.

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

(A) Processing including control command transmission by the main control unit 201 to the intermediate unit 202 and the prize ball control unit 204 will be described with reference to the flowcharts shown in FIGS.
First, the main control unit 201 executes an initial setting process associated with power-on of the pachinko gaming machine 1 (see step S1 in FIG. 3), and then proceeds to step S2. When the power is turned on to the pachinko gaming machine 1, the peripheral board starts up and initializes the RAM area in order to reliably capture the control command transmitted from the main control board. After entering the state, the main control board is configured to stand up. As an initial setting process, the main control unit 201 sets, for example, a predetermined value to the stack pointer in advance, and waits for the intermediate unit 202 and the peripheral unit to enter the standby state described above for a predetermined time (for example, , About 1 second).

In step S2, the main control unit 201 transmits a power-on command to the intermediate unit 202 and the prize ball control unit 204, and then proceeds to step S3. When the power-on command is transmitted, the intermediate unit 202 transmits the power-on command to the sub-control unit 203. When the power-on command is transmitted, the sub-control unit 203 controls the design display unit 104 and the lamp control unit 205 for the effect at the time of power-on, specifically, the gaming machine is in a non-game state. A customer waiting demo command for displaying a customer waiting demo screen or a control command for lighting a lamp or the like is transmitted.
Note that the power-on command for executing the above-described power-on processing is that the main control unit 201 is connected to the intermediate unit 202 via the intermediate unit 202 and the sub-control unit 203 via the intermediate unit 202 after the control boards are started up. A control command to be transmitted to the control unit 204 or the like, and a control command to transmit initial control information for controlling a game at the time of start-up after power-on, for example, control mode, backup data, and the like. The power-on command also includes a control command for transmitting these control modes, backup data, and the like that are executed when the reset button of the gaming machine is pressed.

  In step S <b> 3, the main control unit 201 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 201 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 0, the main control unit 201 proceeds to step S10 described later. On the other hand, if the determination result in step S3 is “YES”, that is, if the number of undrawn prizes is 0, the main control unit 201 proceeds to step S4.

  In step S4, the main control unit 201 measures the time that has elapsed since the start of the customer waiting demonstration, and then proceeds to step S5. In step S5, the main control unit 201 determines whether or not a predetermined time has elapsed since the customer waiting demonstration was started. If the determination result in step S5 is “YES”, that is, if a predetermined time has elapsed since the start of the customer waiting demonstration, the main control unit 201 proceeds to step S6.

  In step S6, the main control unit 201 transmits a customer waiting demonstration command to the intermediate unit 202, and then proceeds to step S7. When the customer waiting demo command is transmitted, the intermediate unit 202 transmits the customer waiting demo command to the sub-control unit 203. When the customer waiting demonstration command is transmitted, the sub-control unit 203 transmits a control signal for 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 the predetermined time has not elapsed since the start of the customer waiting demonstration, the main control unit 201 proceeds to step S7. In step S <b> 7, the main control unit 201 detects whether or not the first start port detection unit 221 detects that a game ball has entered the first start port 105 or the second start port detection unit 225 detects that the second start port 120 has entered the second start port 120. It is determined whether or not a game ball is detected. If the determination result in step S7 is “YES”, that is, whether the first start port detection unit 221 detects that a game ball has entered the first start port 105 or the second start port detection unit 225 performs the second start. If a game ball has entered the mouth 120, the main control unit proceeds to step S8.

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

  In step S8, the main control unit 201 clears the time measured since the start of the customer waiting demonstration, and then proceeds to step S9. In step S9, the main control unit 201 adds 1 to the number of undrawn winning prizes, and then proceeds to step S10. In step S10, the main control unit 201 randomly acquires one jackpot determination random number from random numbers (for example, 0 to 250) prepared in advance, and then proceeds to step S11. In step S11, the main control unit 201 proceeds to step S12 shown in FIG.

  In step S12 shown in FIG. 4, the main control unit 201 determines whether or not the jackpot determination random number acquired in the process of step S10 is a predetermined jackpot random number. In step S12, in the case of an outlier random number, it is also determined whether it is “out of reach” or “out of reach”. 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 201 proceeds to step S13.

  In step S13, the main control unit 201 transmits a jackpot reach command (design variation command) to the intermediate unit 202, and then proceeds to step S14. When the jackpot reach command (design variation command) is transmitted, the intermediate unit 202 transmits the jackpot reach command (design variation command) to the sub-control unit 203. In step S14, the main control unit 201 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 201 repeats the same determination. When the symbol variation time has elapsed, the determination result in step S14 is “YES”, and the main control unit 201 proceeds to step S15.

  In step S15, the main control unit 201 transmits a symbol stop command to the intermediate unit 202, and then proceeds to step S16. When the symbol stop command is transmitted, the intermediate unit 202 transmits the symbol stop command to the sub-control unit 203. In step S16, the main control unit 201 transmits a jackpot start command to the intermediate unit 202, and then proceeds to step S17. When the jackpot start command is transmitted, the intermediate unit 202 transmits the jackpot start command to the sub-control unit 203. In step S17, the main control unit 201 sequentially transmits to the intermediate unit 202 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. When the jackpot command corresponding to each round is sequentially transmitted, the intermediate unit 202 sequentially transmits the jackpot command corresponding to each round to the sub-control unit 203. In step S18, the main control unit 201 transmits a jackpot end command to the intermediate unit 202, and then proceeds to step S22. When the jackpot end command is transmitted, the intermediate unit 202 transmits the jackpot end command to the sub-control unit 203.

  On the other hand, if the determination result in step S12 is “NO”, that is, if the jackpot determination random number obtained in the process of step S10 is not a predetermined jackpot random number, the main control unit 201 proceeds to step S19. In step S19, the main control unit 201 determines that the “reach with a reach” command is “out of reach reach (design variation command)”, and the “out of reach” command is a “out of command command (design variation command)”. ”Is transmitted to the intermediate unit 202, and then the process proceeds to step S20. When the detachment reach command or the detachment command is transmitted, the intermediate unit 202 transmits the control command (design variation command) to the sub-control unit 203.

  In step S20, the main control unit 201 determines whether the symbol variation time has elapsed. If the determination result in step S20 is “NO”, that is, if the symbol variation time has not elapsed, the main control unit 201 repeats the determination. When the symbol variation time elapses, the determination result in step S20 is “YES”, and the main control unit 201 proceeds to step S21. In step S21, the main control unit 201 transmits a symbol stop command to the intermediate unit 202, and then proceeds to step S22. When the symbol stop command is transmitted, the intermediate unit 202 transmits the symbol stop command to the sub-control unit 203.

  In step S22, the main control unit 201 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 201 returns to step S3 shown in FIG. repeat.

  On the other hand, if the determination result in step S22 is “YES”, that is, if the power of the pachinko gaming machine 1 is turned off, the main control unit 201 proceeds to step S23. In step S <b> 23, the main control unit 201 transmits a termination process command to the intermediate unit 202 and then terminates a series of processes. When the end process command is transmitted, the intermediate unit 202 transmits the end process command to the sub-control unit 203.

  Here, FIG. 5 shows a timing chart as an example of the transmission timing of the jackpot related command (the jackpot reach command, the jackpot start command, the jackpot command, the jackpot end command). The jackpot reach command shown in FIG. 5A is transmitted more frequently and randomly than a jackpot actually occurs. Also, the jackpot start command shown in FIG. 5 (2) is transmitted only once when shifting to the jackpot state when a jackpot has actually occurred. Furthermore, the jackpot command shown in FIG. 5 (3) is continuously transmitted for each round after shifting to the jackpot state. Also, the jackpot end command shown in FIG. 5 (4) is transmitted only once when all rounds of the jackpot state are completed and the normal state is entered.

(B) Next, processing by the sub-control unit 203 will be described. In the following, regarding the process of the sub-control unit 203 at the time of symbol change (when a jackpot reach command (see step S13 shown in FIG. 4) or a loss reach command (see step S19 shown in FIG. 4) is received) and a jackpot reach command. explain.

(I) First, the symbol variation processing by the sub-control unit 203 will be described with reference to the flowchart shown in FIG.
First, the sub-control unit 203 sends a jackpot reach command (see step S13 shown in FIG. 4) or an unreachable reach command (see step S19 shown in FIG. 4) from the main control unit 201 via the intermediate unit 202. It is determined whether any of the above has been received (see step S31 in FIG. 6). If the determination result is “NO”, the sub-control unit 203 repeats the determination. When either the jackpot reach command or the miss reach command is received, the determination result in step S31 is “YES”, and the sub-control unit 203 proceeds to step S32.

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

  In step S34, the sub-control unit 203 transmits an effect start command for each variation effect to the symbol display unit 104 and the lamp control unit 205, and then proceeds to step S35. In step S <b> 35, the sub control unit 203 determines whether or not the production time of the variation effect has elapsed. If the determination result in step S35 is “NO”, that is, if the production time of the variation effect has not elapsed, the sub-control unit 203 proceeds to step S36.

  In step S36, the sub-control unit 203 determines whether a symbol stop command (see steps S15 and S21 shown in FIG. 4) has been received from the main control unit 201 via the intermediate unit 202. If the determination result in step S36 is “NO”, that is, if the symbol stop command has not been received, the sub-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 sub-control unit 203 proceeds to step S37. Also, if the determination result in step S35 is “YES”, that is, if the production time of the variation effect has elapsed, the sub-control unit 203 proceeds to step S37. In step S <b> 37, the sub control unit 203 transmits an effect stop command to the symbol display unit 104 and the lamp control unit 205 and then ends a series of processes.

(Ii) Next, the process of jackpot by the sub-control unit 203 will be described with reference to the flowchart shown in FIG.

If the determination result is “NO”, the sub-control unit 203 repeats the determination. When the jackpot start command is received, the determination result in step S41 is “YES”, and the sub-control unit 203 proceeds to step S42.

  In step S42, the sub 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 sub-control unit 203 determines whether or not a round-by-round jackpot command (see step S17 shown in FIG. 4) is received from the main control unit 201 via the intermediate unit 202. If the determination result is “NO”, the sub-control unit 203 repeats the determination. Then, when the round-by-round jackpot command is received, the determination result in step S43 is “YES”, and the sub-control unit 203 proceeds to step S44.

  In step S44, the sub control unit 203 transmits a round processing command corresponding to the round jackpot command received to the symbol display unit 104 and the lamp control unit 205, 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. 4) is received from the main control unit 201 via the intermediate unit 202. If the determination result is “NO”, the sub-control unit 203 repeats the determination. When the jackpot end command is received, the determination result in step S45 is “YES”, and the sub-control unit 203 proceeds to step S46. In step S46, the sub control unit 203 transmits a jackpot end processing command to the symbol display unit 104 and the lamp control unit 205, and then ends a series of processing.

(C) Next, lamp control processing by the lamp control unit 205 will be described. Here, processing when a symbol variation command is received from the sub-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. 6) has been received from the sub-control unit 203 (see step S51 in FIG. 8). 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 an effect stop command (see step S37 shown in FIG. 6) is received from the sub 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 sub-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 sub control unit 203 and the lamp control unit 205 perform various processes based on the control command supplied from the main control unit 201. The same applies to the prize ball control unit 204. Hereinafter, “peripheral part” is used as a generic term for the sub-control unit 203, the prize ball control unit 204, and the lamp control unit 205.
On the other hand, as described above, the main control board (main control unit) and the peripheral board among the fraudulent acts that are performed on gaming machines and forcibly pay out game media such as medals and game balls regardless of the game. The following are related to (peripheral part).

(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) ROM replacement in (2) above with an unauthorized substrate (spoofed substrate) between the main control board and the peripheral substrate. The peripheral part performs an illegal operation by the illegal control command data output from the illegal control part. This is because the existing control command data does not include information that can be identified by the sender, so that the transmitted control command data is transmitted from the legitimate control unit in the peripheral unit that receives the control command data. This is because it is not possible to identify whether or not it is a thing.

  In addition to the above-described fraudulent acts, for example, when control command data is transmitted from the main control unit to the peripheral unit, external noise or mechanical vibration is applied to the gaming machine. Due to the influence of noise and the like, a bit error may occur in the control command data, and the control command data may be changed. In this case, when the control command data that should originally be transmitted to the peripheral portion is control command data other than the jackpot command, a bit error occurs and the control command data is changed to jackpot command data. Even if the above-described fraud is not performed, an unreasonable amount of game media (for example, game balls and medals) is paid out to the player, and the game hall suffers a great deal of damage.

  Therefore, in order to prevent malfunctions of the gaming machine due to the above-described fraud and noise, in the pachinko gaming machine 1 according to the first embodiment, an intermediate unit 202 is provided between the main control unit 201 and the sub-control unit 203. Provided, when the control command supplied from the main control unit 201 is a predetermined control command, the intermediate unit 202 decrypts the authentication data, re-encrypts, format conversion, intermediate between the authentication command and the control command data, etc. An intermediate process in a narrow sense such as calculation is performed, and an authentication process (narrow sense) is performed between the intermediate unit 202 and the sub-control unit 203. Here, the predetermined control command specifically refers to a jackpot reach command for causing the peripheral portion to execute the processing of the reach state before jackpot.

  Next, an example of a data format of a control signal supplied from the main control unit 201 to the intermediate unit 202 will be described with reference to a schematic diagram shown in FIG. As shown in FIG. 9 (1), the normal control signal 300 output from the main control unit 201 includes control command data 301 and accompanying data 302. The control command data 301 in this case is data unique to the control command other than the jackpot reach command described above. The accompanying data 302 is data accompanying the control command data 301, and is data necessary for processing based on the control command data 301 such as data indicating the current gaming state, for example.

  On the other hand, when the control command data 301 in the control signal is data specific to the jackpot reach command, the main control unit 201, in addition to the control command data 301 and the accompanying data 302, as shown in FIG. A control signal with authentication data 310 including the authentication data 303 is generated and output. Although not shown in FIG. 9, the normal control signal 300 and the control signal with authentication data 310 include BCC (Block Check Character) and the like, as with control signals transmitted in general data communication. It is. The BCC is an error detection code added to each transmission block in order to check data errors that occur in the data transmission process. The same applies to the control signals with authentication data 311 and 312, the normal control signal 320, and the control signals with intermediate processing information 321, 322, and 323 described later.

  As described above, by including the authentication data 303 in the control signal, an increase in communication load between the main control unit 201 and the peripheral unit can be suppressed as compared with a case where the authentication data is transmitted alone. Further, by including the authentication data 303 in the control signal, it is possible to reduce the risk that the authentication data 303 is extracted from the communication data and analyzed as compared with the case where the authentication data 303 is transmitted alone. . Further, since the authentication process is performed only when jackpot reach command data is transmitted, the rate at which the processing load of the main control unit 201 increases due to the authentication process can be suppressed.

  Further, since the intermediate unit 202 is provided between the main control unit 201 and the sub control unit 203, there is a difference in processing capability between the CPU 201a configuring the main control unit 201 and the CPU 203a configuring the sub control unit 203. Even if there is a difference in capacity between the ROM 201b constituting the main control unit 201 and the ROM 203b constituting the sub control unit 203, the difference can be absorbed by the intermediate unit 202. For example, when the processing capacity of the CPU 201a configuring the main control unit 201 has a margin compared to the processing capacity of the CPU 203a configuring the sub-control unit 203, the main control unit 201 performs complicated or advanced encryption on the authentication data. The encryption operation result obtained by performing the operation is supplied to the intermediate unit 202, and the intermediate unit 202 performs a relatively simple or low-level encryption operation on the received encryption operation result. The calculation result is supplied to the sub-control unit 203. If the capacity of the ROM 203b that constitutes the sub-control unit 203 is larger than the capacity of the ROM 201b that constitutes the main control unit 201, the main control unit 201 can use the authentication data as it is or a relatively simple or low encryption. The encryption operation result obtained by performing the encryption operation is supplied to the intermediate unit 202, and the intermediate unit 202 performs a complicated or advanced re-encryption operation on the received encryption operation result, or the encryption operation After the result is decrypted, an intermediate operation result obtained by performing an intermediate operation such as performing a more complicated or advanced re-encryption operation is supplied to the sub-control unit 203. This is not only the case where there is a difference in the processing capacity of the CPUs 201a and 203a and the capacity of the ROMs 201b and 203b constituting the main control unit 201 and the sub control unit 203, respectively. When all or part of one of the programs executed by the CPU 201a constituting the main control unit 201 or the CPU 203a constituting the sub control unit 203 is changed (version upgrade, etc.), or in the format of authentication data, etc. The same applies when there is a significant difference.

  Further, the intermediate unit 202 performs intermediate processing in a narrow sense such as decryption, re-encryption, control command data, etc., or format conversion on the authentication data 303, and the peripheral portion performs this intermediate processing in the narrow sense. A narrowly-defined authentication process is performed on the authentication data 303. Therefore, since the peripheral portion authenticates not only the main control unit 201 but also the intermediate unit 202, pachinko games caused by fraudulent acts and noises on the main control unit 201 such as (1) to (3) described above. In addition to the malfunction of the machine 1, it is possible to prevent the malfunction of the gaming machine due to fraud and noise similar to the above-described (1) to (3) with respect to the intermediate unit 202, and to improve the security. it can. In this case, if the peripheral part performs further multi-stage authentication, it is more difficult to perform illegal acts on the main control part 201 and the intermediate part 202.

  Further, since the authentication data 303 is added only to the control command data 301 of the jackpot reach command, it is only necessary to add an authentication process (narrow sense) regarding the jackpot reach command to the program executed by the sub-control unit 203. Accordingly, since it is not necessary to design a new timing for the entire program executed by the sub-control unit 203, the authentication function in a narrow sense is compared with the case where the authentication data 303 is added to the control command data 301 of all control commands. It can be realized more easily and with less work man-hours, such as the design of the timing of adding the function, the implementation of the function, and the verification of the function.

  The authentication data 303 is data for the peripheral part to authenticate (narrowly define) that the main control part 201 is a regular main control part and the intermediate part 202 is a regular intermediate part. Specifically, the authentication data 303 is generated by, for example, an identification number (ID) uniquely assigned to the pachinko gaming machine 1 or the CPU 201a, a value of a program counter (PC), a stack point value, and a random number generator. Generated using random numbers, program code inspection values (hereinafter collectively referred to as “authentication basic values”), or the above authentication basic values and jackpot reach commands (and associated data described later) (for example, four arithmetic operations) , Logical operation, etc.). Here, the program code check value is a hash function calculation, parity check, cyclic redundancy check (CRC), check sum (Check Sum) for all or part of the program stored in the ROM 201b. A value obtained by performing error detection calculation such as a value that can detect the correctness of the program code.

  The intermediate unit 202 transmits intermediate processing information obtained by performing intermediate processing in a narrow sense such as decryption, re-encryption, and intermediate calculation between the authentication data 303 and control command data, etc., to the peripheral unit for the authentication data 303, The peripheral part performs authentication (narrow sense) using the authentication data 303 after the peripheral part performs decryption and extraction of the authentication data 303 from the above-described intermediate processing information, so that the peripheral part is based on the obtained authentication result. It can be determined whether the output source of the control signal is the regular main control unit 201 or the regular intermediate unit 202. In order for the peripheral unit to perform authentication in a narrow sense using the authentication data 303, data necessary for authentication (hereinafter referred to as “expected value” or the like) is stored in advance in a storage unit such as a ROM constituting the peripheral unit. Needless to say that it is necessary. Further, it is possible to detect unauthorized rewriting of the program code stored in the ROM 201b of the main control unit 201 or unauthorized replacement of the ROM 201b of the main control unit 201.

  Note that the main control unit 201 may generate different authentication data 303 for each control signal. Specifically, for example, the address range in which the program code in the ROM 201b used for generating the authentication data 303 is stored is different, or the error detection calculation for generating the authentication data 303 is different. Like that. Further, the data used for generating the authentication data 303 is not limited to the program code, but may be arbitrary data stored in the ROM 201b (for example, data stored in a specific address of the data table).

Further, the authentication data 303 may include data related to the control command data 301 and accompanying data 302 transmitted together with the authentication data 303. The data related to the control command data 301 and the accompanying data 302 is obtained by performing an operation using the error detection method as described above on the control command data 301 and the accompanying data 302 itself, or the control command data 301 and the accompanying data 302. Value. In general, an unauthorized control unit attempts to cause a peripheral unit to perform an unauthorized operation by transmitting control command data different from that of the regular main control unit 201. If the authentication data 303 is generated using the control command data 301 and the accompanying data 302 transmitted together with the authentication data 303, even if the authentication data 303 is reused by an unauthorized control unit, the authentication data 303 and the control command Can not be matched, and fraud can be detected.
In addition, not only the above-described fraud, but due to electrical noise, mechanical vibration, etc., if a bit error occurs in the control command data and the control command data is changed, authentication is not successful. It is also possible to prevent the execution of the control command corresponding to the control command data changed due to the noise or the like.

  When the authentication data 303 includes data related to the control command data 301 and the accompanying data 302, the main control unit 201 encrypts the authentication command 303 by combining the control command data 301 and the data related to the accompanying data 302 and the authentication basic value. Generate.

  The control signal with authentication data is not limited to the control signal with authentication data 310 arranged in the order of the control command data 301, the accompanying data 302, and the authentication data 303 as shown in FIG. As shown in (3), the authentication data 303 is 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. 9 (4). Alternatively, the control signal 312 with authentication data into which the authentication data 303 is inserted may be used. Further, the authentication data 303 may be output separately from the control command data 301 and the accompanying data 302. For example, after transmitting a control signal including jackpot reach command data, the authentication data 303 may be added at the time of the third control signal transmission. Further, the timing for generating the authentication data 303 is not particularly limited, and may be generated before the jackpot reach command data is transmitted.

  Next, an example of a data format of a control signal supplied from the intermediate unit 202 to the sub control unit 203 will be described with reference to a schematic diagram shown in FIG. When the normal control signal 300 shown in FIG. 9 (1) is supplied from the main control unit 201, the intermediate unit 202 includes control command data 301 and accompanying data 302 as shown in FIG. 10 (1). A normal control signal 320 is generated and supplied to the sub-control unit 203. On the other hand, when, for example, control signals with authentication data 310 to 312 shown in FIGS. 9 (2) to (4) are supplied from the main control unit 201, the intermediate unit 202 is narrowly defined with respect to the authentication data 303. Intermediate processing information 304 is generated, for example, control signals 321 to 323 with intermediate processing information shown in FIGS. 10 (2) to (4) are generated and supplied to the sub-control unit 203.

(D) Next, control signal transmission / reception processing performed between the main control unit 201, the intermediate unit 202, and the peripheral unit will be described. Hereinafter, control signal transmission / reception processing between the main control unit 201 and the intermediate unit 202 will be described with reference to the flowcharts shown in FIGS. 11 and 12, but between the main control unit 201 and the prize ball control unit 204. The control signal transmission / reception process is also performed in the same procedure.

  FIG. 11 is a flowchart illustrating an example of control signal transmission processing by the main control unit 201. First, the main control unit 201 determines whether it is currently the transmission timing of control command data (see step S61 in FIG. 11). When the determination result is “NO”, the main control unit 201 repeats the same determination. When the control command data transmission timing comes, the determination result in step S61 is “YES”, and the main control unit 201 proceeds to step S62.

  In step S62, the main control unit 201 determines whether or not the control command to be transmitted this time is a jackpot reach command. If the determination result in step S62 is “YES”, that is, if the control command transmitted this time is a jackpot reach command, the main control unit 201 proceeds to step S63. In step S63, the main control unit 201 sets the control command data 301 (big hit reach command data) and the accompanying data 302 in a predetermined storage area of the RAM 201c, and then proceeds to step S64.

  In step S64, the main control unit 201 generates the authentication data 303, and then proceeds to step S65. As the authentication data 303, for example, all checksums (program code inspection values) of programs stored in the ROM 201b can be considered. The authentication data 303 may be obtained by encrypting the above-described program code inspection value or the like with a relatively simple encryption method such as Caesar encryption, single-substitution encryption, or enigma. Further, the order of the process of step S63 and the process of step S64 may be switched.

  In step S65, the main control unit 201 generates a control signal (control signal with authentication data) including the control command data 301, the accompanying data 302, and the authentication data 303 generated in the processes of steps S63 and S64 described above. Then, after the transmission to the intermediate unit 202, a series of processing ends.

  On the other hand, if the determination result in step S62 is “NO”, that is, if the control command transmitted this time is not a jackpot reach command, the main control unit 201 proceeds to step S66. In step S66, the main control unit 201 sets the control command data 301 (control command data of a control command other than the jackpot reach command) and the accompanying data 302 in a predetermined storage area of the RAM 201c, and then proceeds to step S67. In step S67, the main control unit 201 generates a control signal (ordinary control signal) including the control command data 301 and the accompanying data 302 generated in the process of step S66 described above, and transmits the control signal to the intermediate unit 202. Terminate the process.

  As described above, the main control unit 201 adds the authentication data 303 to the control command data 301 only when the jackpot reach command data is transmitted to the intermediate unit 202. The jackpot reach is more frequent than the jackpot. 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, since the authentication process is performed only when the jackpot reach command data is transmitted, the rate at which the processing load of the main control unit 201 increases due to the authentication process can be suppressed.

  Next, control signal transmission / reception processing by the intermediate unit 202 will be described. FIG. 12 is a flowchart illustrating an example of control signal transmission / reception processing by the intermediate unit 202. First, the intermediate unit 202 determines whether or not a control signal transmitted from the main control unit 201 has been received (see step S71 in FIG. 12). If the determination result is “NO”, the intermediate unit 202 repeats the determination. And if the control signal transmitted from the main control part 201 is received, the judgment result of step S71 will be "YES", and the intermediate part 202 will progress to step S72.

  In step S72, the intermediate unit 202 determines whether or not the authentication data 303 is included in the received control signal. If the determination result in step S72 is “YES”, that is, if the authentication data 303 is included in the received control signal, the intermediate unit 202 proceeds to step S73. Here, whether or not the authentication data 303 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, This is performed by determining whether or not any bit constituting the data 302 or separately provided identification data (not shown) indicates that the authentication data 303 is included. In the process of step S72, the intermediate unit 202 does not determine whether the authentication data 303 is included in the received control signal, but the control command data 301 included in the control signal is jackpot reach command data. It may be determined whether or not there is.

  In step S73, the intermediate unit 202 extracts the authentication data 303 from the control signal, performs intermediate processing in a narrow sense on the authentication data 303, and then proceeds to step S74. As an intermediate process in a narrow sense, for example, the following processes (a) to (d) or a combination of these processes is performed.

(A) If the authentication data 303 is encrypted by the main control unit 201, it is decrypted.
(B) The authentication basic value is restored from the authentication data 303 which is not encrypted by the main control unit 201 or decrypted by the process (a).
(C) The authentication basic value restored in the process of (b), the authentication data 303 not encrypted by the main control unit 201, or the authentication data 303 decrypted in the process of (a), and the authentication The control command data received together with the data 303, the conversion control command data obtained by converting the control command data based on a predetermined conversion formula, or a predetermined numerical value such as a random number generated by the random number generator, etc. Perform intermediate operations such as logical operations.
(D) The authentication basic value restored by the process of (b), the authentication data decrypted by the process of (a) or the authentication data 303 encrypted by the main control unit 201, the intermediate operation result in (c) Re-encrypt one.

  In step S74, the intermediate unit 202 controls the control signal (with intermediate processing information) including the control command data 301 and the accompanying data 302 included in the control signal, and the intermediate processing information 304 obtained by the processing in step S73 described above. Control signal) is generated and transmitted to the sub-control unit 203, and then a series of processing ends.

  On the other hand, if the determination result in step S72 is “NO”, that is, if the authentication data 303 is not included in the received control signal, that is, if it is a normal control signal, the intermediate unit 202 performs step S75. Proceed to In step S75, the intermediate unit 202 transmits the transmitted normal control signal as it is to the sub-control unit 203, and then ends a series of processing.

  Next, control signal reception processing by the sub-control unit 203 will be described. FIG. 13 is a flowchart illustrating an example of control signal reception processing by the sub-control unit 203. First, the sub-control unit 203 determines whether or not the control signal transmitted from the intermediate unit 202 has been received (see step S81 in FIG. 13). If the determination result is “NO”, the sub-control unit 203 repeats the determination. When the control signal transmitted from the intermediate unit 202 is received, the determination result in step S81 is “YES”, and the sub-control unit 203 proceeds to step S82.

  In step S82, the sub control unit 203 determines whether or not the intermediate control information 304 is included in the received control signal. If the determination result in step S82 is “YES”, that is, if the intermediate control information 304 is included in the received control signal, the sub-control unit 203 proceeds to step S83. Here, the determination as to whether or not the intermediate processing information 304 is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, or whether the control command data 301 or It is determined whether or not any bit constituting the accompanying data 302 or separately provided identification data (not shown) indicates that the intermediate processing information 304 is included, or included in the control signal It may be determined whether or not the control command data 301 to be processed is jackpot reach command data set in advance for performing the authentication process.

  In step S83, the sub-control unit 203 extracts the intermediate processing information 304 from the control signal, performs authentication processing (broad sense), obtains the result (authentication result), and then proceeds to step S84. As the authentication process (broad sense), for example, the following processes (i) to (iv) or a combination of these processes is performed.

  (I) The authentication basic value restored by the intermediate unit 202 from the authentication data 303 generated by the main control unit 201 and constituting the intermediate processing information 304, encrypted by the main control unit 201 and decrypted by the intermediate unit 202 If any of the authentication data 303, the authentication data 303 encrypted by the main control unit 201, and the intermediate calculation result is encrypted or re-encrypted, it is decrypted.

(Ii) The authentication basic value restored by the intermediate unit 202 from the intermediate operation result that is not encrypted or decrypted in (i), and the authentication data 303 that is not encrypted or decrypted by the intermediate unit 202 Take out one of the following.
(Iii) If the authentication data 303 extracted in (ii) is encrypted or re-encrypted, it is decrypted.
(Iv) Using the authentication basic value or the authentication data 303 obtained in (i) to (iii), authentication (narrow sense) is performed for one or both of the main control unit 201 and the intermediate unit 202.

  The authentication process (in a narrow sense) in (iv) is performed by the following method, for example. That is, for example, it is determined whether or not the basic authentication value or the authentication data 303 (hereinafter referred to as “authentication data 303 etc.”) obtained in (i) to (iii) matches the expected value. Note that the sub-control unit 203 may determine whether or not the authentication data 303 or the like and the expected value have a predetermined relationship, instead of whether or not the authentication data 303 or the like matches the expected value. The predetermined relationship means, for example, a relationship in which a value obtained by performing a predetermined calculation on the authentication data 303 or the like matches an expected value.

  The expected value used for verification by the sub-control unit 203 is stored in advance in a predetermined storage area of the ROM 203b constituting the sub-control unit 203, for example, at the time of manufacturing. In addition, it is good also as transmitting the expected value which the sub control part 203 uses for collation to the sub control part 203 from another structure part. Examples of other components include a prize ball control unit 204 and a dedicated processing unit for generating an expected value of authentication data (hereinafter referred to as an “expected value calculation unit”). The expected value calculation unit may transmit an expected value stored in advance to the sub-control unit 203 or may generate an expected value for each matching process. In addition, a coefficient necessary for calculating an expected value may be transmitted from an external device to the sub-control unit 203 or the expected value calculation unit via an external connection interface (not shown). As described above, if the expected value of the authentication data 303 or the like is not stored in advance in the predetermined storage area of the ROM 203b that constitutes the sub-control unit 203, the authentication data 303 or the like can be obtained from another component. It becomes possible to change it after the fact.

  In step S84, the sub-control unit 203 determines whether or not the authentication result obtained in step S83 indicates that the authentication has succeeded. If the determination result in step S84 is “YES”, that is, if the authentication result obtained in the process in step S83 indicates that the authentication has succeeded, the sub-control unit 203 proceeds to step S85. In addition, when the determination result of step S82 is “NO”, that is, when the intermediate control information 304 is not included in the received control signal, that is, when it is a normal control signal, the sub-control unit 203 Proceed to step S85.

  In step S85, the sub-control unit 203 performs a process based on the control command data 301 and the accompanying data 302, and then ends a series of processes. On the other hand, if the determination result in step S84 is “NO”, that is, if the authentication result obtained in step S83 does not indicate that the authentication has succeeded, the sub-control unit 203 proceeds to step S86. . In step S86, the sub-control unit 203 discards the control command data 301 and the accompanying data 302, and manages the symbol display unit 104, the lamp control unit 205, or the pachinko gaming machine 1 with a notification signal for notifying an illegal act. After the transmission to the center control device or the like, the series of processing ends. In the process of step S86, the sub-control unit 203 may perform only one of data discarding and notification.

  Based on the supplied notification signal, the symbol display unit 104, the lamp control unit 205, and the like perform an effect that notifies the main control unit 201 that there is a possibility that fraud has been performed. 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 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, it is sufficient that the employee notices the state when passing in front of the pachinko gaming machine 1. Further, 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.

  In addition, information regarding the gaming state of the pachinko gaming machine 1 such as “Big hit” or “Probability changing” may be included in the notification signal. Based on the information regarding 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 and probability fluctuations. Moreover, you may make it output the information regarding a gaming state as another signal, without including in a notification signal. In this case, the employee determines whether there is a risk of fraud based on both the notification signal and the information regarding the gaming state.

  Next, an example of the mutual relationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 will be described with reference to the flowcharts shown in FIGS. When the control command data 301 is control command data of a control command other than the jackpot reach command, the main control unit 201 sets the control command data 301 and the accompanying data 302 in a predetermined storage area of the RAM 201c (see step S91 in FIG. 14). After that, the process proceeds to step S92. In step S <b> 92, the main control unit 201 generates a normal control signal including the control command data 301 and the accompanying data 302 and transmits it to the intermediate unit 202.

  After receiving the normal control signal transmitted in step S92 (see step S93), intermediate unit 202 proceeds to step S94. In step S94, the intermediate unit 202 transmits the transmitted normal control signal to the sub-control unit 203 as it is. After receiving the normal control signal transmitted in step S94 (see step S95), the sub control unit 203 proceeds to step S96. In step S96, the sub control unit 203 performs processing based on the control command data 301 and the accompanying data 302 included in the normal control signal. Thus, when the control command data 301 is control command data of a control command other than the jackpot reach command, the intermediate unit 202 includes the received control command data 301 and accompanying data 302 without performing intermediate processing. The normal control signal not including the authentication data 303 is transmitted to the sub-control unit 203 as it is, and the sub-control unit 203 performs processing based on the control command data 301 and the accompanying data 302 included in the received normal control signal. Do.

  On the other hand, when the control command data 301 is jackpot reach command data, the main control unit 201 sets the control command data 301 and the accompanying data 302 in a predetermined storage area of the RAM 201c (see step S101 in FIG. 15), and then the step Proceed to S102. In step S102, the main control unit 201 generates the authentication data 303, and then proceeds to step S103. In step S <b> 103, the main control unit 201 generates an authentication data-added control signal including control command data 301, accompanying data 302, and authentication data 303, and transmits the generated control signal to the intermediate unit 202.

  On the other hand, the intermediate unit 202 proceeds to step S105 after receiving the control signal with authentication data transmitted in the process of step S103 (see step S104). In step S105, the intermediate unit 202 performs intermediate processing in a narrow sense on the authentication data 303 included in the control signal with authentication data, and then proceeds to step S106. In step S106, the intermediate unit 202 performs control with intermediate processing information including the control command data 301 and accompanying data 302 included in the control signal with authentication data, and the intermediate processing information 304 obtained in the processing of step S105. A signal is generated and transmitted to the sub-control unit 203.

  Thereby, the sub-control unit 203 receives the control signal with intermediate processing information transmitted in the process of step S106 (see step S107), and then proceeds to step S108. In step S108, the sub-control unit 203 performs authentication processing using the authentication data 303 and the like included in the control signal with intermediate processing information, and then proceeds to step S109. In step S109, the sub control unit 203 determines whether or not the authentication result obtained in the process of step S108 indicates that the authentication has succeeded. If the determination result in step S109 is “YES”, that is, if the authentication result obtained in the process in step S108 indicates that the authentication has succeeded, the sub-control unit 203 proceeds to step S110. In step S110, the sub control unit 203 performs processing based on the control command data 301 and the accompanying data 302.

  On the other hand, if the determination result in step S109 is “NO”, that is, if the authentication result obtained in the process in step S108 does not indicate that the authentication has succeeded, the sub-control unit 203 proceeds to step S111. . In step S <b> 111, the sub control unit 203 discards the control command data 301 and the accompanying data 302 and transmits a notification signal for notifying an illegal act to the symbol display unit 104 and the lamp control unit 205.

  Note that the intermediate unit 202 may perform intermediate processing in a narrow sense on the authentication data 303 not when the authentication data 303 is received, but when the plurality of authentication data 303 is received. In this case, when the intermediate unit 202 receives the control signal with authentication data including the jackpot reach command data, the accompanying data, and the authentication data for the first time, for example, the intermediate unit 202 does not perform the intermediate processing in a narrow sense and directly sends it to the sub control unit 203. Send. Then, when the intermediate unit 202 receives the control signal with authentication data including the jackpot reach command data, the accompanying data, and the authentication data for the second time, the intermediate unit 202 performs intermediate processing in a narrow sense on the authentication data 303 received for the first time. At this time, the intermediate unit 202 may perform narrowly-defined intermediate processing for both the authentication data 303 received first time and the authentication data 303 received second time. In this way, if narrow intermediate processing is performed at the time of receiving a plurality of authentication data 303, the narrow intermediate processing is erroneously performed when extra data is added to the control signal due to an error. Risk can be reduced. The same applies to the authentication process in the sub-control unit 203.

  As described above, in the pachinko gaming machine 1 according to the first embodiment, when the jackpot reach command data is transmitted, the intermediate unit 202 decrypts, encrypts, re-encrypts the authentication data 303, Sub-controls the so-called “naked data” that has been subjected to narrow intermediate processing (conversion processing) such as intermediate computation and then transmitted to the sub-control unit 203 and has not been subjected to any conversion processing while being transmitted from the main control unit 201 It is not transmitted to the unit 203 as it is. Further, the sub-control unit 203 performs an authentication process using the authentication data 303 for authenticating the validity of the main control unit 201. For this reason, the following fraud can be detected. Further, if the authentication data 303 including the jackpot reach command data and the accompanying data transmitted this time is generated, the authentication data 303 is prevented from being reused by an unauthorized main control unit, and the pachinko gaming machine 1 is more surely secured. Can detect fraudulent activity.

(1) Replacing an authorized main control board with an unauthorized main control board (2) 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 (3) ROM replacement described in (2) above with an unauthorized substrate (spoofed substrate) provided between the main control board and the peripheral substrate. If a bit error occurs in the control command data due to static noise or mechanical vibration, and the control command data is changed, the authentication is not successful. It is also possible to prevent execution of a control command corresponding to the control command data.

  Further, in the pachinko gaming machine 1 according to the first embodiment, when the main control unit 201 transmits jackpot reach command data to the peripheral unit, the intermediate unit 202 performs a narrowly-defined intermediate process and the sub-control unit 203 Then, an authentication process for authenticating the legitimacy of the main control unit 201 and the intermediate unit 202 is performed. The jackpot reach is more frequent than the jackpot. 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. In addition, the processing load on the main control unit 201 and the peripheral unit increases by performing authentication processing only during the period when the jackpot reach command data is transmitted, and the processing load on the main control unit 201 and the peripheral unit increases. The ratio to do can be suppressed.

  Further, in the pachinko gaming machine 1 according to the first embodiment, when the control command data included in the control signal transmitted from the main control unit 201 is jackpot reach command data, the control command data 301 and the accompanying data 302 are authenticated. Since the data 303 is added, an increase in communication load between the main control unit 201 and the peripheral unit can be suppressed as compared with the case where the authentication data 303 is transmitted alone. Further, by including the authentication data 303 in the control signal, it is possible to reduce the risk that the authentication data 303 is extracted from the communication data and analyzed as compared with the case where the authentication data 303 is transmitted alone. .

  Further, since the intermediate unit 202 performs a narrowly-defined intermediate process and the sub-control unit 203 performs an authentication process, the gaming machine resulting from fraudulent acts, noise, or the like with respect to the main control unit such as the above (1) to (3) In addition to this malfunction, it is possible to prevent malfunctions of the gaming machine due to fraud and noise similar to the above-described (1) to (3) with respect to the intermediate section 202, and security can be improved.

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

  In addition, since the configuration of the authentication program and the production program is relatively simple, it is easy to maintain consistency with other functions. In addition, even if the presentation process is different for each model of the pachinko gaming machine 1, since the authentication process can be shared, it is easy to design a program for each model of the pachinko gaming machine 1 and shorten the design time. Work efficiency can be improved.

  Further, according to the first embodiment, since the intermediate unit 202 is provided between the main control unit 201 and the sub control unit 203, the CPU 201 a configuring the main control unit 201 and the CPU 203 a configuring the sub control unit 203. Even if there is a difference in capacity between the ROM 201b that constitutes the main control unit 201 and a ROM 203b that constitutes the sub control unit 203, the difference is Can be absorbed. For example, when the processing capacity of the CPU 201a configuring the main control unit 201 has a margin compared to the processing capacity of the CPU 203a configuring the sub-control unit 203, the main control unit 201 performs complicated or advanced encryption on the authentication data. The encryption operation result obtained by performing the operation is supplied to the intermediate unit 202, and the intermediate unit 202 performs a relatively simple or low-level encryption operation on the received encryption operation result. The calculation result is supplied to the sub-control unit 203. If the capacity of the ROM 203b that constitutes the sub-control unit 203 is larger than the capacity of the ROM 201b that constitutes the main control unit 201, the main control unit 201 can use the authentication data as it is or a relatively simple or low encryption. The encryption operation result obtained by performing the encryption operation is supplied to the intermediate unit 202, and the intermediate unit 202 performs a complicated or advanced re-encryption operation on the received encryption operation result, or the encryption operation After the result is decrypted, an intermediate operation result obtained by performing an intermediate operation such as performing a more complicated or advanced re-encryption operation is supplied to the sub-control unit 203. This is not only the case where there is a difference in the processing capacity of the CPUs 201a and 203a and the capacities of the ROMs 201b and 203b constituting the main control unit 201 and the sub control unit 203, respectively. When all or a part of one of the programs executed by the CPU 201a constituting the control unit 201 or the CPU 203a constituting the sub-control unit 203 is changed (for example, version upgrade), the format of authentication data, etc. The same applies when differences occur.

Embodiment 2. FIG.
Next, Embodiment 2 of the present invention will be described with reference to the drawings. First, regarding the hardware configuration of the pachinko gaming machine that is one of the gaming machines according to the second embodiment of the present invention, the hardware configuration of the pachinko gaming machine 1 according to the first embodiment of the present invention shown in FIG. 1 and FIG. The hardware configuration is the same. However, the main control unit 201 generates two different first authentication data 305 and second authentication data 306 from the authentication basic value in order to be authenticated by the sub control unit 203, and the first authentication data 305 and the second authentication data 306 are generated. The data 306 is added to the jackpot reach command and supplied to the intermediate unit 202. The intermediate unit 202 performs narrowly-defined intermediate processing on the first authentication data 305 and the second authentication data 306 transmitted from the main control unit 201, and the obtained first intermediate processing information 307 and second intermediate processing information are obtained. 308 is supplied to the sub-control unit 203. The sub-control unit 203 uses the first intermediate processing information 307 and the second intermediate processing information 308 transmitted from the intermediate unit 202 to execute the first stage and second stage authentication processes. The data format of the control signal supplied from the main control unit 201 to the intermediate unit 202 and the data format of the control signal supplied from the intermediate unit 202 to the sub-control unit 203 are the same as those of the main control unit 201 in the first embodiment. The data format of the control signal supplied to the unit 202 is different from the data format of the control signal supplied from the intermediate unit 202 to the sub-control unit 203 (see FIGS. 9, 10, 16, and 17). Along with the difference in the data format of the control signal, the control signal transmission process by the main control unit 201, the control signal reception / transmission process by the intermediate unit 202, and the control signal reception by the sub control unit 203, which constitute the pachinko gaming machine. The processing is different as described below. Generally speaking, in the second embodiment of the present invention, the sub-control unit 203 executes a two-step authentication process, so that the security is further enhanced as compared with the first embodiment of the present invention described above. Since all the first authentication data 305 and the second authentication data 306 used in the two-step authentication process are transmitted simultaneously with the control command data 301, the transmission method of the authentication data and the timing for adding the authentication function It can be realized more easily and with less work man-hours than design / function implementation / function verification. Further, since the two-step authentication process can be executed every time the control command data 301 is transmitted, the accuracy of authentication can be increased. Further, by executing the two-step authentication process, even if an authentication method with a low authentication strength is used, an authentication effect with an authentication strength substantially equivalent to that when using a one-step authentication method with a high authentication strength is obtained. It becomes possible. Therefore, even if one-step authentication processing with high authentication strength cannot be executed because the processing capability of the sub-control unit 203 is low, by combining at least two authentication functions with low authentication strength but different authentication methods An authentication function with substantially high authentication strength can be added.

  Next, an example of a data format of a control signal supplied from the main control unit 201 to the intermediate unit 202 will be described with reference to a schematic diagram shown in FIG. First, the data format of the normal control signal supplied from the main control unit 201 to the intermediate unit 202 is the same as the data format of the normal control signal 300 shown in FIG. On the other hand, when the control command data 301 in the control signal is jackpot reach command data, the main control unit 201 adds the first authentication data to the control command data 301 and the accompanying data 302 as shown in FIG. An authentication data-added control signal 330 including 305 and second authentication data 306 is generated and supplied to the intermediate unit 202. Here, the first authentication data 305 and the second authentication data 306 are authentication data used when the sub-control unit 203 performs the first-stage authentication and the second-stage authentication.

  The control signal with authentication data is a control signal with authentication data 330 arranged in the order of control command data 301, accompanying data 302, first authentication data 305, and second authentication data 306 as shown in FIG. For example, as shown in FIG. 16 (2), the first authentication data 305 and the second authentication data 306 are used as a control signal with authentication data 331 provided at the head of the control signal, or in FIG. 16 (3). As shown, a control signal 332 with authentication data in which first authentication data 305 and second authentication data 306 are inserted between the control command data 301 and the accompanying data 302 may be used. Further, as shown in FIGS. 16 (1) to (3), the first authentication data 303 and the second authentication data 304 do not need to be arranged continuously, and are arranged between the control command data 301 and the accompanying data 302. Alternatively, the arrangement order of the first authentication data 303 and the second authentication data 304 may be reversed. Further, the first authentication data 305 and the second authentication data 306 may be output separately from the control command data 301 and the accompanying data 302. For example, after transmitting a control signal including jackpot reach command data, the first authentication data 305 and the second authentication data 306 may be added when the control signal is transmitted for the third time. Further, the timing for generating the first authentication data 305 and the second authentication data 306 is not particularly limited, and may be generated before the jackpot reach command data is transmitted.

  Next, an example of a data format of a control signal supplied from the intermediate unit 202 to the sub control unit 203 will be described with reference to a schematic diagram shown in FIG. First, when the normal control signal 300 shown in FIG. 9 (1) is supplied from the main control unit 201, the data format of the normal control signal generated by the intermediate unit 202 and supplied to the sub-control unit 203 is shown in FIG. This is the same as the normal control signal 320 shown in (1).

  For example, when control signals with authentication data 320 to 322 shown in FIGS. 16 (1) to (3) are supplied from the main control unit 201, the intermediate unit 202 receives the first authentication data 305 and the second authentication data. Intermediate processing in a narrow sense is performed on the data 304 to generate first intermediate processing information 305 and second intermediate processing information 306. For example, the control signal with intermediate processing information 340 shown in FIGS. ˜342 etc. are generated and supplied to the sub-control unit 203. The arrangement order of the control command data 301, the accompanying data 302, the first intermediate processing information 305, and the second intermediate processing information 306 includes the control commands described above in addition to the variations shown in FIGS. 17 (1) to (3). Variations similar to the arrangement order of the data 301, the accompanying data 302, the first authentication data 305, and the second authentication data 306 are conceivable.

  Next, control signal transmission / reception processing performed between the main control unit 201, the intermediate unit 202, and the peripheral unit will be described. Hereinafter, the transmission / reception process of the control signal between the main control unit 201 and the intermediate unit 202 will be described with reference to the flowcharts shown in FIGS. 18 and 19, but between the main control unit 201 and the prize ball control unit 204. The control signal transmission / reception process is also performed in the same procedure.

  FIG. 18 is a flowchart illustrating an example of control signal transmission processing by the main control unit 201. 18, processes corresponding to the processes in FIG. 11 are denoted by the same reference numerals, and detailed description thereof is omitted. The control signal transmission process by the main control unit 201 shown in FIG. 18 is different from the control signal transmission process by the main control unit 201 shown in FIG. 11 in that the processes in steps S68 to S70 are replaced with the processes in steps S64 and S65. Is newly provided. Below, only the process of step S68-S70 is demonstrated.

  In step S68, the main control unit 201 generates the first authentication data 305, and then proceeds to step S69. In step S69, the main control unit 201 generates the second authentication data 306, and then proceeds to step S70. The first authentication data 305 may be, for example, all checksums (program code inspection values) of programs stored in the ROM 201b. In this case, the second authentication data 306 is different from, for example, the first authentication data 305. A program code inspection value generated by the generation method, an identification number (ID) uniquely assigned to the CPU 201a, or a value of the program counter (PC) can be considered. Either one or both of the first authentication data 305 and the second authentication data 306 is obtained by encrypting the above-described program code inspection value or the like with a relatively simple encryption method such as Caesar encryption, single substitution encryption, or enigma. You may use what you did. Further, the order of the processes in steps S63, S68, and S69 may be changed.

  In step S70, the main control unit 201 controls the control signal (including the control command data 301, the accompanying data 302, the first authentication data 305, and the second authentication data 306 generated by the processes in steps S63, S68, and S69 described above. A control signal with authentication data) is generated and transmitted to the intermediate unit 202, and then a series of processing is terminated.

  In this way, the main control unit 201 adds the first authentication data 305 and the second authentication data 306 to the control command data 301 only when the jackpot reach command data is transmitted to the intermediate unit 202. Since the authentication process is performed only when the jackpot reach command data is transmitted, the rate at which the processing load of the main control unit 201 increases due to the authentication process can be suppressed.

  Next, control signal transmission / reception processing by the intermediate unit 202 will be described. FIG. 19 is a flowchart illustrating an example of control signal transmission / reception processing by the intermediate unit 202. 19, processes corresponding to the processes in FIG. 12 are denoted by the same reference numerals, and detailed description thereof is omitted. The control signal transmission / reception processing by the intermediate unit 202 shown in FIG. 19 is different from the control signal reception / transmission processing by the intermediate unit 202 shown in FIG. 12 in that the processing in steps S76 to S78 is replaced with the processing in steps S73 and S74. Is newly provided. Below, only the process of step S76-S78 is demonstrated.

  In step S76, the intermediate unit 202 extracts the first authentication data 305 from the control signal, performs intermediate processing in a narrow sense on the first authentication data 305, and then proceeds to step S77. Since the method for the intermediate process for the first authentication data is the same as the method for the intermediate process for the authentication data 303 in the first embodiment, the description thereof is omitted.

In step S77, the intermediate unit 202 extracts the second authentication data 306 from the control signal, performs intermediate processing in a narrow sense on the second authentication data 306, and then proceeds to step S78. Since the method for the intermediate processing for the second authentication data is the same as the method for the intermediate processing for the authentication data 303 in the first embodiment, the description thereof is omitted.
In step S78, the intermediate unit 202 includes the control command data 301 and the accompanying data 302 included in the control signal, and the first intermediate processing information 307 and the second intermediate data obtained in the processing of steps S76 and S77 described above, respectively. A control signal including the processing information 308 (control signal with intermediate processing information) is generated and transmitted to the sub-control unit 203, and then a series of processing ends.

  Next, control signal reception processing by the sub-control unit 203 will be described. FIG. 20 is a flowchart illustrating an example of control signal reception processing by the sub-control unit 203. 20, processes corresponding to those in FIG. 13 are given the same reference numerals, and detailed descriptions thereof are omitted. The control signal reception process by the sub-control 203 shown in FIG. 20 is different from the control signal reception process by the sub-control unit 203 shown in FIG. 13 in that the processes in steps S87 to S89 are replaced with the processes in steps S83 and S84. This is a newly provided point. Below, only the process of step S87-S89 is demonstrated.

  In step S87, the sub-control unit 203 extracts the first intermediate processing information 307 from the control signal, performs the first-stage authentication process (broad sense), obtains the result (first authentication result), and then performs step S88. Proceed to Since the technique in the first stage authentication process (broad sense) is the same as the technique of the authentication process (broad sense) in the first embodiment, the description thereof is omitted.

  In step S88, the sub-control unit 203 extracts the second intermediate processing information 308 from the control signal, performs the second stage authentication process, obtains the result (second authentication result), and then proceeds to step S89. Since the method in the second stage authentication process (broad sense) is the same as the method of the authentication process (broad sense) in the first embodiment, the description thereof is omitted. Note that the order of the processing in step S87 and the processing in step S88 may be interchanged.

  In step S89, the sub-control unit 203 determines whether or not both the first authentication result obtained in step S87 and the second authentication result obtained in step S88 indicate that the authentication has succeeded. to decide. If the determination result of step S89 is “YES”, that is, the first authentication result obtained by the process of step S87 and the second authentication result obtained by the process of step S88 both indicate that the authentication was successful. If so, the sub control unit 203 proceeds to step S85. On the other hand, if the determination result in step S89 is “NO”, that is, either the first authentication result obtained in the process in step S87 or the second authentication result obtained in the process in step S88 has been successfully authenticated. If not shown, the sub-control unit 203 proceeds to step S86.

  The sub-control unit 203 may determine whether or not the first authentication result obtained in the process of step S87 indicates that the authentication has succeeded after the process of step S87 is completed. If the determination result is “NO”, that is, if the first authentication result obtained in the process of step S87 does not indicate that the authentication has succeeded, the sub-control unit 203 performs the second operation in step S88. What is necessary is just to comprise so that it may progress to step S86, without performing step | paragraph authentication. In other words, if the first stage authentication is unsuccessful, the second stage authentication is omitted to simplify and speed up the process.

  Next, an example of the mutual relationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 will be described with reference to the flowchart shown in FIG. First, in the case where the control command data 301 is control command data of a control command other than the jackpot reach command, the interrelationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 is as described above. Since the control command data 301 of the form 1 is control command data of a control command other than the jackpot reach command, it is the same as the mutual relationship of the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203. The description is omitted.

  In FIG. 21, processes corresponding to the processes in FIG. 15 are denoted by the same reference numerals, and detailed description thereof is omitted. The mutual relationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 shown in FIG. 21 is mutually related to the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 shown in FIG. The difference from the relationship is that steps S112 to S120 are newly provided in place of the steps S102, S103, S105, S106, S108, and S109. Below, only the process of step S112-S120 is demonstrated.

  In step S112, the main control unit 201 generates the first authentication data 305, and then proceeds to step S113. In step S113, the main control unit 201 generates the second authentication data 306, and then proceeds to step S114. In step S <b> 114, the main control unit 201 generates an authentication data-added control signal including control command data 301, accompanying data 302, first authentication data 305, and second authentication data 306, and transmits it to the intermediate unit 202.

  Next, in step S115, the intermediate unit 202 performs intermediate processing in a narrow sense on the first authentication data 305 included in the control signal with authentication data, and then proceeds to step S116. In step S116, the intermediate unit 202 performs intermediate processing in a narrow sense on the second authentication data 306 included in the control signal with authentication data, and then proceeds to step S117. In step S117, the intermediate unit 202 includes the control command data 301 and the accompanying data 302 included in the control signal with authentication data, and the first intermediate processing information 307 and the second information obtained in the processes in steps S115 and S116. A control signal with intermediate processing information including the intermediate processing information 308 is generated and transmitted to the sub-control unit 203.

  Next, in step S118, the sub-control unit 203 performs the first stage authentication process using the first intermediate process information 307 and the like included in the control signal with intermediate process information, and then proceeds to step S119. In step S119, the sub-control unit 203 performs the second-stage authentication process using the second intermediate process information 308 included in the control signal with intermediate process information, and then proceeds to step S120. In step S120, the sub-control unit 203 determines whether or not both the first authentication result obtained in step S118 and the second authentication result obtained in step S119 indicate that the authentication has succeeded. to decide. If the determination result of step S120 is “YES”, that is, the first authentication result obtained by the process of step S118 and the second authentication result obtained by the process of step S119 are both successfully authenticated. If there is, the sub-control unit 203 proceeds to step S110. On the other hand, if the determination result in step S120 is “NO”, that is, either the first authentication result obtained in step S118 or the second authentication result obtained in step S119 has been successfully authenticated. Is not indicated, the sub-control unit 203 proceeds to step S111.

  Note that the intermediate unit 202 may perform intermediate processing in a narrow sense on the first authentication data 305 not every time the first authentication data 305 is received, but at the time when a plurality of first authentication data 305 is received. good. In this case, for example, when the intermediate unit 202 receives the control signal with authentication data including the jackpot reach command data, the accompanying data, the first authentication data 305 and the second authentication data 306 for the first time, the intermediate unit 202 performs intermediate processing in a narrow sense. Without being transmitted to the sub-control unit 203 as it is. When the intermediate unit 202 receives the control signal with authentication data including the jackpot reach command data, the accompanying data, the first authentication data 305, and the second authentication data 306 for the second time, the first authentication data received for the first time Intermediate processing in a narrow sense for 305 is performed. At this time, the intermediate unit 202 may perform narrowly-defined intermediate processing on both the first authentication data 305 received first time and the first authentication data 305 received second time. In this way, if narrow intermediate processing is performed at the time of receiving a plurality of first authentication data 305, the intermediate processing in the narrow sense is erroneously performed when extra data is added to the control signal due to an error. The risk of being lost can be reduced. The same applies to the authentication process in the first stage and the second stage in the sub-control unit 203.

  As described above, in the pachinko gaming machine according to the second embodiment, when the jackpot reach command data is transmitted, the intermediate unit 202 decrypts the first authentication data 305 and the second authentication data 306. A so-called "" which is subjected to narrow intermediate processing (conversion processing) such as encryption, re-encryption, and intermediate calculation, and then transmitted to the sub-control unit 203 and is not subjected to any conversion processing while being transmitted from the main control unit 201. The “bare data” is not transmitted to the sub-control unit 203 as it is. Further, the sub-control unit 203 performs a two-step authentication process using the first authentication data 305 and the second authentication data 306 for authenticating the validity of the main control unit 201. For this reason, the effect similar to the case of Embodiment 1 mentioned above can be acquired.

  Further, in the pachinko gaming machine according to the second embodiment of the present invention, the sub-control unit 203 executes a two-step authentication process, so that the security is further enhanced as compared with the first embodiment of the present invention described above. In addition, since all the first authentication data 305 and the second authentication data 306 used in the two-step authentication process are transmitted at the same time as the control command data 301, a timing for adding a transmission method of authentication data and an authentication function It can be realized more easily and with less work man-hours than design, function implementation, and function verification. Further, since the two-step authentication process can be executed every time the control command data 301 is transmitted, the accuracy of authentication can be increased. Further, by executing the two-step authentication process, even if an authentication method with a low authentication strength is used, an authentication effect with an authentication strength substantially equivalent to that when using a one-step authentication method with a high authentication strength is obtained. It becomes possible. Therefore, even if one-step authentication processing with high authentication strength cannot be executed because the processing capability of the sub-control unit 203 is low, by combining at least two authentication functions with low authentication strength but different authentication methods An authentication function with substantially high authentication strength can be added.

Embodiment 3 FIG.
Next, Embodiment 3 of the present invention will be described with reference to the drawings. First, regarding the hardware configuration of the pachinko gaming machine that is one of the gaming machines according to the third embodiment of the present invention, the hardware of the pachinko gaming machine 1 according to the first embodiment of the present invention shown in FIGS. The hardware configuration is the same. Further, the data format of the control signal supplied from the main control unit 201 to the intermediate unit 202 and the data format of the control signal supplied from the intermediate unit 202 to the sub control unit 203 are also described in the first embodiment of the present invention. Is the same as the data format of the control signal supplied to the intermediate unit 202 and the data format of the control signal supplied to the sub-control unit 203 by the intermediate unit 202 (see FIGS. 9 and 10).

  However, in the third embodiment of the present invention, as in the case of the second embodiment, the sub-control unit 203 executes a two-step authentication process. However, in the second embodiment described above, all the first authentication data 305 and the second authentication data 306 used in the two-step authentication process are transmitted simultaneously with the control command data 301. 3, all the first authentication data and the second authentication data used in the two-step authentication process are transmitted from the main control unit 201 to the intermediate unit 202 in two steps. Thereby, in the third embodiment of the present invention, it is possible to prevent the unauthorized person from grasping all authentication data as compared with the second embodiment described above, and thus security is further strengthened. Yes. Further, in the third embodiment of the present invention, as in the second embodiment described above, by executing the two-step authentication process, even if an authentication method with a low authentication strength is used, one step with a high authentication strength is performed. It is possible to obtain an authentication effect with an authentication strength substantially equivalent to the case of using the authentication method. Therefore, even if one-step authentication processing with high authentication strength cannot be executed because the processing capability of the sub-control unit 203 is low, by combining at least two authentication functions with low authentication strength but different authentication methods An authentication function with substantially high authentication strength can be added. Furthermore, in the third embodiment of the present invention, compared to the second embodiment described above, the transmission method of the first authentication data and the second authentication data and the design / function implementation / function of the timing for adding the authentication function. It can be realized more easily and with fewer man-hours such as verification.

  Next, control signal transmission / reception processing performed between the main control unit 201, the intermediate unit 202, and the peripheral unit will be described. Hereinafter, the transmission / reception process of the control signal between the main control unit 201 and the intermediate unit 202 will be described with reference to the flowcharts shown in FIGS. 22 and 23, but between the main control unit 201 and the prize ball control unit 204. The control signal transmission / reception process is also performed in the same procedure.

  FIG. 22 is a flowchart illustrating an example of control signal transmission processing by the main control unit 201. 22, processes corresponding to the processes in FIG. 11 are denoted by the same reference numerals, and detailed description thereof is omitted. The control signal transmission process by the main control unit 201 shown in FIG. 22 is different from the control signal transmission process by the main control unit 201 shown in FIG. 11 in that the processes in steps S121 to S123 are replaced with the processes in steps S64 and S65. Is newly provided. Below, only the process of step S121-S123 is demonstrated.

  In step S121, the main control unit 201 determines whether or not the first authentication data has been transmitted. If the determination result in step S121 is “NO”, that is, if the first authentication data has not yet been transmitted, the main control unit 201 proceeds to step S122. Here, the determination of whether or not the first authentication data has been transmitted is made by determining whether or not a flag indicating that the first authentication data has been transmitted is set in a predetermined area of the RAM 201c, for example. Do. In step S122, the main control unit 201 generates the first authentication data, and then proceeds to step S65. A specific example of the first authentication data is the same as the first authentication data 305 in the above-described second embodiment, and a description thereof will be omitted. The first authentication data may be obtained by encrypting the above-described program code inspection value or the like with a relatively simple encryption method such as Caesar encryption, single-substitution encryption, or enigma.

  On the other hand, if the determination result in step S121 is “YES”, that is, if the first authentication data has already been transmitted, the main control unit 201 proceeds to step S123. In step S123, the main control unit 201 generates the second authentication data, and then proceeds to step S65. A specific example of the second authentication data is the same as the second authentication data 306 in the above-described second embodiment, and a description thereof will be omitted. Note that the second authentication data may be obtained by encrypting the above-described program code inspection value or the like with a relatively simple encryption method such as Caesar encryption, single-substitution encryption, or enigma.

The control signal transmission / reception processing by the intermediate unit 202 shown in FIG. 22 is different from the control signal reception / transmission processing by the intermediate unit 202 shown in FIG. 12 in that the processing of steps S131 to S135 is replaced with the processing of steps S73 and S74. Is newly provided. Below, only the process of step S131-S135 is demonstrated. Although not shown in FIG. 23, in the reception process of the first authentication data and the second authentication data, for example, a flag indicating that the first authentication data has been received is set in a predetermined area of the RAM 202c. It is done by judging whether or not.

  In step S131, the intermediate unit 202 determines whether or not the first authentication data is included in the received control signal. If the determination result in step S131 is “YES”, that is, if the received first control data is included in the received control signal, the intermediate unit 202 proceeds to step S132. Here, the determination of whether or not the first authentication data is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, This is performed by determining whether or not any bit constituting the accompanying data 302 or identification data (not shown) provided separately indicates that the first authentication data is included. In the process of step S131, the intermediate unit 202 does not determine whether or not the first authentication data is included in the received control signal, but the control command data 301 included in the control signal is the jackpot reach command data. It may be determined whether or not.

  In step S132, the intermediate unit 202 extracts the first authentication data from the control signal, performs intermediate processing in a narrow sense on the first authentication data, and then proceeds to step S133. Since the method for the intermediate processing for the first authentication data is the same as the method for the intermediate processing for the first authentication data 305 in the second embodiment, the description thereof is omitted.

  In step S133, the intermediate unit 202 controls the control signal (intermediate processing information) including the control command data 301 and the accompanying data 302 included in the control signal and the first intermediate processing information obtained in the processing of step S132 described above. A control signal) is generated and transmitted to the sub-control unit 203, and then a series of processing ends.

  On the other hand, if the determination result in step S131 is “NO”, that is, if the received control signal includes the second authentication data instead of the first authentication data, the intermediate unit 202 proceeds to step S134. . In step S134, the intermediate unit 202 extracts the second authentication data from the control signal, performs intermediate processing in a narrow sense on the second authentication data, and then proceeds to step S135. Since the method for the intermediate processing for the second authentication data is the same as the method for the intermediate processing for the second authentication data 306 in the second embodiment, the description thereof is omitted.

  In step S135, the intermediate unit 202 controls the control signal (intermediate processing information) including the control command data 301 and the accompanying data 302 included in the control signal, and the second intermediate processing information obtained in the processing of step S134 described above. A control signal) is generated and transmitted to the sub-control unit 203, and then a series of processing ends.

  Next, control signal reception processing by the sub-control unit 203 will be described. FIG. 24 is a flowchart illustrating an example of control signal reception processing by the sub-control unit 203. 24, processes corresponding to the processes in FIG. 13 are denoted by the same reference numerals, and detailed description thereof is omitted. The difference between the control signal reception process by the sub-control 203 shown in FIG. 24 and the control signal reception process by the sub-control unit 203 shown in FIG. 13 is that the processes in steps S141 to S146 are replaced with the processes in steps S83 and S84. This is a newly provided point. Below, only the process of step S141-S146 is demonstrated. Although not shown in FIG. 24, in the reception process of the first authentication data and the second authentication data, for example, a flag indicating that the first authentication data has been received is set in a predetermined area of the RAM 203c. It is done by judging whether or not.

  In step S141, the sub-control unit 203 determines whether or not the first control information is included in the received control signal. If the determination result in step S141 is “YES”, that is, if the first control information is included in the received control signal, the sub-control unit 203 proceeds to step S142. Here, the determination as to whether or not the first intermediate processing information is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, and whether the control command data 301 is included in the control signal. Alternatively, it is performed by determining whether or not any bit constituting the accompanying data 302 or separately provided identification data (not shown) indicates that the first intermediate processing information is included. In the process of step S141, the intermediate unit 202 does not determine whether or not the first control information is included in the received control signal, but the control command data 301 included in the control signal is the jackpot reach command. It may be determined whether it is data.

  In step S142, the sub-control unit 203 extracts the first intermediate processing information from the control signal, performs the first-stage authentication process (broad sense), obtains the result (first authentication result), and then proceeds to step S143. move on. Since the technique in the first stage authentication process (broad sense) is the same as the technique of the first stage authentication process (broad sense) in the second embodiment, description thereof is omitted. In step S143, the sub control unit 203 determines whether or not the first authentication result obtained in the process of step S142 indicates that the authentication has succeeded. If the determination result of step S143 is “YES”, that is, if the first authentication result obtained by the process of step S142 indicates that the authentication has succeeded, the sub-control unit 203 proceeds to step S85. . On the other hand, if the determination result of step S143 is “NO”, that is, if the first authentication result obtained by the process of step S142 does not indicate that the authentication has succeeded, the sub control unit 203 performs step S86. Proceed to

  On the other hand, if the determination result of step S141 is “NO”, that is, if the first control information is not included in the received control signal, the sub-control unit 203 proceeds to step S144. In step S144, the sub-control unit 203 determines whether or not the received control signal includes the second intermediate processing information. If the determination result in step S144 is “YES”, that is, if the second control information is included in the received control signal, the sub-control unit 203 proceeds to step S145. Here, the determination as to whether or not the second intermediate processing information is included in the control signal is, for example, whether or not the data amount of the control signal is larger than that of the normal control signal, Alternatively, it is performed by determining whether or not any bit constituting the accompanying data 302 or separately provided identification data (not shown) indicates that the second intermediate processing information is included. In the process of step S144, the intermediate unit 202 does not determine whether or not the second control information is included in the received control signal, but the control command data 301 included in the control signal is the jackpot reach command. It may be determined whether it is data.

  In step S145, the sub-control unit 203 extracts the second intermediate processing information from the control signal, performs the second stage authentication process (broad sense), obtains the result (second authentication result), and then proceeds to step S146. move on. Since the method in the second stage authentication process (broad sense) is the same as the method of the second stage authentication process (broad sense) in the second embodiment, the description thereof is omitted.

  In step S146, the sub-control unit 203 determines whether or not the second authentication result obtained by the process of step S145 indicates that the authentication has succeeded. If the determination result in step S146 is “YES”, that is, if the second authentication result obtained in the process in step S145 indicates that the authentication has succeeded, the sub-control unit 203 proceeds to step S85. . In addition, when the determination result of step S144 is “NO”, that is, when the received control signal includes neither the first intermediate processing information nor the second intermediate processing information, that is, when it is a normal control signal. In addition, the sub-control unit 203 proceeds to step S85. On the other hand, when the determination result of step S146 is “NO”, that is, when the second authentication result obtained by the process of step S145 does not indicate that the authentication is successful, the sub control unit 203 performs step S86. Proceed to

  In the process of step S146, the sub-control unit 203 indicates that both the first authentication result obtained in the process of step S142 and the second authentication result obtained in the process of step S145 have been successfully authenticated. It may be determined whether or not. If the determination result in step S146 is “YES”, that is, both the first authentication result obtained in step S142 and the second authentication result obtained in step S145 have been successfully authenticated. In step S85, the sub-control unit 203 proceeds to step S85. If the determination result in step S146 is “NO”, that is, the first authentication result obtained in step S142 or the process in step S145. If any one of the second authentication results obtained in step 2 does not indicate that the authentication is successful, the sub-control unit 203 may be configured to proceed to step S86.

  Next, an example of the mutual relationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 will be described with reference to the flowcharts shown in FIGS. First, in the case where the control command data 301 is control command data of a control command other than the jackpot reach command, the interrelationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 is as described above. Since the control command data 301 of the form 1 is control command data of a control command other than the jackpot reach command, it is the same as the mutual relationship of the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203. The description is omitted.

  FIG. 25 shows the main control unit 201 and the intermediate unit when the control command data 301 is jackpot reach command data and this control command data 301, accompanying data 302, and a control signal with authentication data including the first authentication data are transmitted. 202 is a flowchart illustrating an example of a mutual relationship between processes executed by 202 and the sub-control unit 203. 25, processes corresponding to the processes in FIG. 15 are denoted by the same reference numerals, and detailed description thereof is omitted. The mutual relationship between the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 shown in FIG. 25 is mutually related to the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 shown in FIG. The difference from the relationship is that steps S151 to S153 are newly provided in place of the steps S102, S103, S105, and S108. Below, only the process of step S151-S153 is demonstrated.

  In step S151, the main control unit 201 generates the first authentication data, and then proceeds to step S103.

  Next, in step S152, the intermediate unit 202 performs intermediate processing in a narrow sense on the first authentication data included in the control signal with authentication data, and then proceeds to step S106.

  Next, in step S153, the sub-control unit 203 performs the first-stage authentication process using the first intermediate process information included in the control signal with intermediate process information, and then proceeds to step S109.

  FIG. 26 shows the main control unit 201 and the intermediate unit when the control command data 301 is jackpot reach command data and this control command data 301, accompanying data 302, and a control signal with authentication data including the second authentication data are transmitted. 202 is a flowchart illustrating an example of a mutual relationship between processes executed by 202 and the sub-control unit 203. 26, processes corresponding to the processes in FIG. 15 are denoted by the same reference numerals, and detailed description thereof is omitted. The mutual processing of the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 shown in FIG. 26 is mutually related to the processes executed by the main control unit 201, the intermediate unit 202, and the sub control unit 203 shown in FIG. The difference from the relationship is that steps S161 to S163 are newly provided in place of the steps S102, S103, S105, and S108. Below, only the process of step S161-S163 is demonstrated.

  In step S161, the main control unit 201 generates the second authentication data, and then proceeds to step S103.

  Next, in step S162, the intermediate unit 202 performs intermediate processing in a narrow sense on the second authentication data included in the control signal with authentication data, and then proceeds to step S106.

  Next, in step S163, the sub-control unit 203 performs the second stage authentication process using the second intermediate process information included in the control signal with intermediate process information, and then proceeds to step S109.

  Note that the intermediate unit 202 may perform intermediate processing in a narrow sense on the first authentication data not at every reception of the first authentication data but at a time when a plurality of first authentication data is received. In this case, for example, when the intermediate unit 202 receives the control signal with authentication data including the jackpot reach command data, the accompanying data, and the first authentication data for the first time, the intermediate process is not performed. Then, when the intermediate unit 202 receives the control signal with authentication data including the jackpot reach command data, the accompanying data, and the first authentication data for the second time, the intermediate unit 202 performs intermediate processing on the first authentication data received for the first time. At this time, the intermediate unit 202 may perform intermediate processing on both the first authentication data received for the first time and the first authentication data received for the second time. In this way, if intermediate processing is performed at the time of receiving a plurality of first authentication data, there is a risk that the intermediate processing will be erroneously performed when extra data is added to the control signal due to an error. Can be reduced. The same applies to the intermediate process for the second authentication data in the intermediate unit 202 and the authentication process for the first authentication data and the second authentication data in the sub-control unit 203.

  Further, the main control unit 201 may transmit the second authentication data after transmitting the first authentication data a plurality of times, instead of transmitting the first authentication data and the second authentication data alternately. In this case, the intermediate unit 202 performs intermediate processing on the first authentication data transmitted once or a plurality of first authentication data transmitted a plurality of times, and includes a control signal with intermediate processing information including the first intermediate processing information. Is transmitted to the sub-control unit 203. Thereby, the sub-control unit 203 uses the first intermediate processing information transmitted every time, the plurality of first intermediate processing information transmitted a plurality of times, or one or a plurality of first intermediate processing information. Second authentication obtained by second-stage authentication performed using one or a plurality of first authentication results and one second intermediate processing information 306 obtained by the first-stage authentication performed. It is determined whether authentication is successful based on the result. If processing is performed in this manner, security can be enhanced.

  As described above, in the pachinko gaming machine according to the third embodiment, when the jackpot reach command data is transmitted, the intermediate unit 202 decrypts the first authentication data 303 and the second authentication data 304. A so-called "" which is subjected to narrow intermediate processing (conversion processing) such as encryption, re-encryption, and intermediate calculation, and then transmitted to the sub-control unit 203 and is not subjected to any conversion processing while being transmitted from the main control unit 201. The “bare data” is not transmitted to the sub-control unit 203 as it is. Further, the sub-control unit 203 performs a two-step authentication process using the first authentication data and the second authentication data for authenticating the validity of the main control unit 201. For this reason, the effect similar to the case of Embodiment 1 mentioned above can be acquired.

  In the pachinko gaming machine according to the third embodiment, the first authentication data and the second authentication data are transmitted to the intermediate unit 202 from the main control unit 201 in two steps. Compared to the above, it is possible to prevent an unauthorized person from grasping all authentication data. Furthermore, compared with the above-described second embodiment, the first authentication data and second authentication data transmission method, the design of the timing for adding the authentication function, the implementation of the function, the verification of the function, etc. are easier and less work. It can be realized with man-hours.

As described above, the embodiments of the present invention have been described in detail with reference to the drawings. However, the specific configuration is not limited to these embodiments, and the design can be changed without departing from the scope of the present invention. Is included in the present invention.
For example, in each of the above-described embodiments, an example in which the intermediate unit 202 is provided between the main control unit 201 and the sub-control unit 203 has been described. However, the present invention is not limited to this, and the main control unit 201 and the prize ball control unit 204 are provided. An intermediate portion may be provided between the two. In this case, the prize ball control unit 204 is not provided with an informing means, but because the two-way communication is possible between the main control unit 201 and the prize ball control unit 204, the authentication is unsuccessful. The prize ball control unit 204 may be configured to transmit data indicating that the authentication is unsuccessful to the main control unit 201 together with the control command data and accompanying data. Then, the main control unit 201 transmits the data indicating the failure to the sub-control unit 203 via the intermediate unit 202, and the sub-control unit 203 determines that the data indicating the failure has occurred. , Let them know that cheating has been done.

Further, in each of the above-described embodiments, an example in which the present invention is applied to the pachinko gaming machine 1 has been shown. The present invention can also be applied to other gaming machines such as a revolving game machine such as a ball ball game machine and a slot machine. Also in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring the same as those of the above-described embodiments.
In addition, each of the above-described embodiments can divert each other's technology as long as there is no particular contradiction or problem in its purpose and configuration. For example, data may be transmitted from the main control unit 201 to the intermediate unit 202 in the format shown in FIG. 9, and data may be transmitted from the intermediate unit 202 to the sub control unit 203 in the format shown in FIG. Further, data may be transmitted from the main control unit 201 to the intermediate unit 202 in the format shown in FIG. 17, and data may be transmitted from the intermediate unit 202 to the sub control unit 203 in the format shown in FIG.
