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

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

  In the first conventional example described above, the CPU mounted in the first peripheral part that controls the lamp, the speaker, etc. performs a predetermined calculation using the first identification information, the second identification information, and the third identification information, and displays it. The CPU mounted on the second peripheral part for controlling the game machine 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 first conventional example described above, one CPU constituting the peripheral portion performs only one authentication process (ID addition process). 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 strengthen security, it is difficult to execute authentication processing by a more complicated calculation than before and authentication processing multiple times.

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

  Further, as described above, since the processing load and the program capacity of the CPU constituting the peripheral portion are increased by causing the CPU constituting the peripheral portion to execute the authentication process in addition to the existing processing, the CPU constituting the peripheral portion is increased. In order to further enhance security, it is difficult to execute authentication processing by a more complicated calculation than before and authentication processing multiple times.

  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 to third 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 is intended to solve the above-described problems as an example, and a gaming machine and a main control unit that can solve these problems An object is to provide a main control board, an intermediate part, a peripheral board, an authentication method, and an authentication program.

  The invention according to claim 11 relates to the authentication method according to claim 10, wherein in the first step, the main control unit uses at least the predetermined program code and the predetermined control command. One authentication value is generated.

  The invention described in claim 12 relates to the authentication method according to any one of claims 9 to 11, wherein in the third step, the peripheral portion has at least one of the plurality of authentication results. When the main control unit indicates that the authentication is unsuccessful, a notification signal for notifying the fact is output.

  According to a thirteenth aspect of the present invention, there is provided an authentication program for causing a computer to realize the function according to any one of the ninth to twelfth aspects.

  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 main control unit obtains at least one authentication data from a plurality of authentication values for authenticating the main control unit a plurality of times, and then supplies the at least one authentication data to the intermediate unit. ing. Therefore, the possibility that each authentication value is analyzed by an unauthorized person can be reduced as compared with a case where an authentication value that has not been subjected to any processing is supplied to the intermediate portion as it is. In addition, when the main control unit generates at least one authentication value using a predetermined program code, it becomes possible to more accurately detect fraud due to falsification of the program executed by the main control unit.

  Further, according to the present invention, since the main control unit supplies at least one authentication data obtained from a plurality of authentication values for authenticating the main control unit a plurality of times to the intermediate unit, a plurality of authentication values are obtained. The number of transmissions and the amount of data can be reduced as compared with the case where they are individually supplied to the intermediate unit. Thereby, the increase in the load with respect to the data communication of a main control part, an intermediate | middle part, and a peripheral part can be suppressed.

  Further, according to the present invention, since the authentication process is executed only by the intermediate part, the processing load of the CPU constituting the peripheral part is increased as compared with the case where only the peripheral part executes the authentication process a plurality of times. There is nothing. For this reason, the processing speed of a peripheral part falls and the trouble that the display for production | presentation is not performed smoothly does not generate | occur | produce.

  In addition, since authentication data and intermediate processing information are added only to a predetermined control command, the program executed by the peripheral part performs processing according to the authentication result obtained from the intermediate processing information added to the predetermined control command. Just add. Therefore, there is no need to design a new timing for the entire program executed by the peripheral part, so processing according to the authentication result is added compared to the case where authentication data and intermediate processing information are added to all control commands. Designing timing, implementing functions, verifying functions, etc. can be achieved more easily and with less work man-hours.

  In addition, according to the present invention, since the intermediate unit that executes the authentication process and the peripheral unit that performs the process according to the authentication result are independent, the authentication program and the process program according to the authentication result Can be designed separately. Accordingly, since the configuration of the authentication program and the processing program corresponding to the authentication result is relatively simple, it is easy to maintain consistency with other functions. In addition, even if the processing according to the authentication result is different for each gaming machine model, the authentication process can be shared, so the program design for each gaming machine model is easy and the design time is reduced. Work efficiency can be improved.

  Furthermore, according to the present invention, since the authentication process is executed only by the intermediate part, the authentication process can be separated from the process executed by the peripheral part, thereby encrypting the authentication process algorithm, authentication data, etc., for example. When the algorithm to be used (hereinafter referred to as “authentication algorithm”) is changed or upgraded, the authentication process can be performed more easily and with fewer man-hours than when the peripheral processing is executed. be able to. Also, even with the same type of gaming machine, it is possible to easily implement different authentication algorithms. As a result, the risk that the authentication data is analyzed can be reduced.

  Further, according to the present invention, when the control command transmitted from the main control unit is a predetermined control command, authentication data is added to the predetermined control command, so compared with the case of transmitting the authentication data alone, An increase in communication load between the main control unit and the intermediate 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 only the intermediate part executes the authentication process, the influence of the processing capacity of the CPU that constitutes the peripheral part, the storage capacity of the ROM that constitutes the peripheral part, or restrictions on the design of the peripheral part, etc. The authentication algorithm can be designed without receiving the authentication, and the addition of the authentication function can be realized more easily. In addition, depending on the processing capacity of the CPU constituting the peripheral part and the storage capacity of the ROM constituting the peripheral part, a method (for example, a data structure) as a result of multiple authentications supplied to the peripheral part by the intermediate part is easy. Can be designed to

  For example, when there is no room in the processing capacity of the CPU constituting the peripheral part or the storage capacity of the ROM constituting the peripheral part, the intermediate part uses a plurality of authentication values obtained from the received authentication data to provide a plurality of main control parts. The intermediate processing information obtained by processing the result of the second authentication by a relatively simple method is supplied to the peripheral portion.

  On the other hand, if there is a margin in the processing capacity of the CPU constituting the peripheral part and the storage capacity of the ROM constituting the peripheral part, the intermediate part uses a plurality of authentication values obtained from the received authentication data. The intermediate processing information obtained by processing the result of the time authentication by a complicated or advanced method is supplied to the peripheral portion.

  Furthermore, when all or a part of one of the programs executed by the CPU constituting the main control unit or the CPU constituting the peripheral part is changed (such as version upgrade), or in the data structure of the data to be communicated, etc. Even when a formal difference occurs between the main control unit and the peripheral unit, it is possible to deal with the main control unit or the peripheral unit in which the program is changed or a difference occurs and the intermediate unit.

  Further, according to the present invention, since the authentication process is performed only when a predetermined control command is transmitted, the rate at which the processing load on the main control unit and the peripheral part increases due to the authentication process can be suppressed.

Value. Here, the second authentication has nothing to do with the first authentication, and the second authentication can be performed regardless of whether the first authentication is successful or unsuccessful. And the case where the second authentication cannot be performed unless the first authentication is successful.

[2] Either or both of the first authentication value and the second authentication value generated in the process [1] are encrypted. Here, as an encryption method, for example, a relatively simple method such as Caesar encryption, single substitution encryption, or enigma can be employed. The same applies to the encryption method used below. Also, the encryption and re-encryption of each data such as the first authentication value or the second authentication value may use the same encryption method or different encryption methods.

When the sub-control unit 203 receives control command data related to the effect transmitted from the main control unit 201 via the intermediate unit 202, the sub-control unit 203 performs a lottery based on the control command data, produces an effect background pattern, a reach effect pattern, An effect such as an appearing character is determined and the determined effect is controlled.
In addition, a symbol display unit 104 is connected to the output side of the sub-control unit 203, and, for example, a symbol change effect display is developed on the symbol display unit 104 according to the content determined by the lottery.

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

In addition to the process outlined above, the sub-control unit 203 executes a process related to information extraction based on a program stored in advance in the ROM 203b when receiving a control signal with intermediate process information. In the present embodiment, the outline of the processing relating to this information extraction is as follows, but not all of these processes are always executed.

[4] A process based on the control command data is performed according to the first authentication result or the second authentication result obtained by any one of the processes [1] to [3].
[5] When either one or both of the first authentication result and the second authentication result indicate unsuccessful authentication, a notification to that effect is made.
The details of the processing related to information extraction will be described later.

In addition, a speaker 277 is connected to the output side of the sub-control unit 203 so that sound is output as determined by the sub-control unit 203.
On the output side of the sub-control unit 203, a lamp control unit 205 that controls the lamp 262, the effect lights 111a and 111b, and the effect agent actuating device 254 is provided. The stage effect actuating device 254 is configured by a motor, a solenoid, and the like that actuate a stage role such as the stage role 115.
The lamp control unit 205 operates the program read from the ROM 205b based on the control command data transmitted from the sub-control unit 203 to execute the effect process, the ROM 205b that stores the program and various effect pattern data, and the CPU 205a. And a RAM 205c functioning as a data work area at the time of the arithmetic processing.

In order to change the irradiation direction of the light from each light 112, drive control for the motor is performed.
In addition, the lamp control unit 205 performs drive control on the solenoid that operates the effector 115 based on the control command data transmitted from the sub-control unit 203, and performs drive control on the motor that operates the collar unit 116. .

  Further, a prize ball control unit 204 is connected to the main control unit 201 so as to be capable of transmitting in both directions. The prize ball control unit 204 performs prize ball control based on a program stored in the ROM 204b. The prize ball control unit 204 includes a CPU 204a that executes a prize ball control process by operating a program stored in the ROM 204b, a RAM 204c that functions as a data work area during the calculation process of the CPU 204a, and the like. Yes.

  The winning ball control unit 204 makes each of the winning ports (first starting port 105, second starting port 120, normal winning port 107, first big winning port 109c, second big winning a prize) to the payout unit 291 connected thereto. Control is performed to pay out the number of prize balls corresponding to the game ball that has entered the mouth 129c). The award ball control unit 204 detects an operation of launching a game ball with respect to the launch unit 292 and controls the launch of the game ball. The payout unit 291 includes a motor for paying out a predetermined number from the game ball storage unit.

  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 in the stack pointer, and the intermediate unit 202, the sub control unit 203, and the prize ball control unit 204 enter the standby state described above. In order to wait, the user waits 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.

  The above power-on command indicates a control command for executing processing associated with power-on after power-on. After each control board is started up, the main control unit 201 passes through the intermediate unit 202 and the intermediate unit 202. Control command transmitted from the sub-control unit 203 and the main control unit 201 to the prize ball control unit 204, and initial control information for controlling a game at the time of start-up after power-on, for example, control mode, backup data, etc. Or a control command for controlling the initial effect display, for example, a control command for starting various demonstration displays such as a customer waiting demonstration. The power-on command also includes a control command for transmitting the control mode, backup data, etc., which is executed when the reset button of the gaming machine is pressed.

  In step S <b> 3, the main control unit 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-up demonstration was started, and then proceeds to step S5. In step S <b> 5, the main control unit 201 determines whether or not a predetermined time has elapsed since the start-up demonstration was started. If the determination result in step S5 is “YES”, that is, if a predetermined time has elapsed since the demonstration at power-on was started, the main control unit 201 proceeds to step S6. It should be noted that the control command for starting the demonstration when the power is turned on may be a customer waiting demo command.

  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 a predetermined time has not elapsed since the start of the power-on demonstration (or the customer waiting demo), the main control unit 201 performs step Proceed to 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 that has been measured since the start of the customer waiting demo (or demo at power-on), and then proceeds to step S9. In step S9, the main control unit 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 a random number counter (for example, counts 0 to 250) prepared in advance, and then proceeds to step S11. In step S11, the main control unit 201 proceeds to step S12 shown in FIG.

  In step S12 shown in FIG. 4, the main control unit 201 refers to the jackpot determination data table stored in advance in the ROM 201b, for example, and the jackpot determination random number acquired in the processing of step S10 is the jackpot determination data table. It is determined whether or not it is a jackpot random value stored in. In step S12, if the acquired jackpot determination random number is an outlier random number, for example, referring to the jackpot determination data table, it is further determined whether it is “out of reach” or “out of reach”. Also judge. 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 includes, in the intermediate unit 202, control data (accompanying data) such as a jackpot type code (whether it is a normal hit or a probability fluctuation, etc.), reach, symbol variation time, and the like. After transmitting the jackpot reach command (design variation command), the process 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 which is an example of the transmission timing of the jackpot related command (the jackpot reach command, the jackpot start command, the jackpot command). The jackpot reach command shown in FIG. 5 (1) is transmitted at random. 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. Further, the jackpot command shown in FIG. 5 (3) is continuously transmitted for each jackpot round after shifting to the jackpot state.

(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.

[1] 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.

[2] Next, the process of jackpot by the sub-control unit 203 will be described with reference to the flowchart shown in FIG.
First, the sub-control unit 203 determines whether or not a jackpot start command (see step S16 shown in FIG. 4) is received from the main control unit 201 via the intermediate unit 202 (see step S41 in FIG. 7). 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 for identifying the sender (main control unit 201). Therefore, in the peripheral unit that receives the control command data, the transmitted control command data is a normal one. This is because it is not possible to identify whether or not the data is transmitted from the correct control unit.

  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, the pachinko gaming machine 1 according to the present embodiment is provided with an intermediate unit 202 between the main control unit 201 and the sub-control unit 203. ing.
In this embodiment, the main control unit 201 authenticates the authentication data obtained from the first and second authentication values for authenticating the main control unit 201 when the output control command is a predetermined control command. Is added to a predetermined control command and supplied to the intermediate unit 202. The intermediate unit 202 performs two authentications using the first and second authentication values obtained from the authentication data acquired from the main control unit 201, and encrypts the first authentication result or the second authentication result. Intermediate processing information obtained by performing intermediate processing such as re-encryption, data structure conversion, and intermediate calculation is supplied to the sub-control unit 203. Then, the sub control unit 203 performs a process according to at least one of the first authentication result or the second authentication result obtained from the intermediate processing information acquired from the intermediate unit 202. Here, the predetermined control command indicates an operation of the pachinko gaming machine 1, for example, an initialization operation or a presentation operation (a jackpot command, a reach command, etc.) or a customer waiting demonstration while the pachinko gaming machine 1 is energized. In order to do this, it refers to a specific control command arbitrarily selected in advance from various control commands transmitted from the main control unit 201 to the sub-control unit 203 via the intermediate unit 202.

  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 predetermined control command described above. The accompanying data 302 is data accompanying the control command data 301, and is control data necessary for executing processing corresponding to the control command data 301 such as data indicating the current gaming state, for example.

  On the other hand, when the control command data 301 in the control signal is data specific to the predetermined control command, the main control unit 201 adds to the control command data 301 and the accompanying data 302 as shown in FIG. The control signal 310 with authentication data 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. Sometimes it is. The BCC is an error detection code added to each transmission block in order to check data errors that occur in the data transmission process. The same applies to the control signals with authentication data 311 and 312, the normal control signal 320, and the control signals with intermediate processing information 321, 322, and 323 described later.

  The control signal with authentication data is not limited to the control signal with authentication data 310 arranged in the order of the control command data 301, the accompanying data 302, and the authentication data 303 as shown in FIG. As shown in (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 command data, the authentication data 303 may be added when the control signal is transmitted for the third time.

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 sub control unit 203 can be suppressed as compared with a case where the authentication data is transmitted alone. Also, 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 control command data of a predetermined control command is transmitted, the rate at which the processing load of the main control unit 201 increases due to the authentication process can be suppressed.
As described above, the authentication data 303 is generated by performing predetermined processing on the first and second authentication values for authenticating the main control unit 201.

  The main control unit 201 obtains the authentication data 303 from the first and second authentication values for authenticating the main control unit 201 twice, and then transmits the authentication data 303 to the intermediate unit 202. Therefore, the possibility that each authentication value is analyzed by an unauthorized person can be reduced as compared with a case where an authentication value that has not been subjected to any processing is supplied to the intermediate unit 202 as it is. In addition, when the first authentication value or the second authentication value is generated using a predetermined program code, the main control unit 201 more accurately detects fraud due to falsification of the program executed by the main control unit 201. And the validity of the program code can be authenticated.

  Further, since the main control unit 201 supplies the authentication data 303 obtained from the first and second authentication values for authenticating the main control unit 201 twice to the intermediate unit 202, a plurality of authentication values are individually set. Compared with the case of supplying to the intermediate unit 202, the number of transmissions and the amount of data can be reduced. Thereby, it is possible to suppress an increase in load on data communication of the main control unit 201, the intermediate unit 202, and the sub control unit 203.

  Also, since the authentication process is executed only by the intermediate unit 202, the processing load on the CPU 203a constituting the sub control unit 203 increases as compared to the case where only the sub control unit 203 executes the authentication process multiple times. There is no. For this reason, the processing speed of the sub-control unit 203 is not reduced, and there is no inconvenience such as display for production not being performed smoothly.

  Since the authentication data 303 and the intermediate processing information 304 are added only to the predetermined control command, the authentication result obtained from the intermediate processing information 304 added to the predetermined control command is added to the program executed by the sub-control unit 203. It is only necessary to add processing according to. Therefore, since it is not necessary to design a new timing for the entire program executed by the sub-control unit 203, the processing according to the authentication result is compared with the case where authentication data and intermediate processing information are added to all control commands. Designing the timing to add the function, implementing the function, verifying the function, etc. can be realized more easily and with less work man-hours.

  Since only the intermediate unit 202 executes the authentication process, the authentication process can be separated from the process executed by the sub-control unit 203. For example, an algorithm for encrypting an authentication process algorithm, authentication data, etc. This is generally referred to as “authentication algorithm”.) When changing or upgrading the version, it is possible to handle the process more easily and with fewer man-hours than when the sub-control unit 203 executes the authentication process. . Further, even with the same model of the pachinko gaming machine 1, it is possible to easily implement different authentication algorithms. As a result, the risk that the authentication data is analyzed can be reduced.

  In addition, since the intermediate unit 202 that executes the authentication process and the sub-control unit 203 that mainly executes the effect process are independent of each other, the authentication program and the effect program can be designed separately. Therefore, 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, since only the intermediate unit 202 executes the authentication process, the processing capacity of the CPU 203a constituting the sub-control unit 203, the storage capacity of the ROM 203b constituting the sub-control unit 203, the design restrictions of the sub-control unit 203, etc. An authentication algorithm can be designed without being affected, and an authentication function can be added more easily. In addition, a method (for example, a result of two-time authentication that the intermediate unit 202 supplies to the sub-control unit 203 according to the processing capability of the CPU 203a configuring the sub-control unit 203 and the storage capacity of the ROM 203b configuring the sub-control unit 203 (for example, , Data structure etc.) can be designed easily.

  For example, if the processing capacity of the CPU 203 a constituting the sub-control unit 203 and the storage capacity of the ROM 203 b constituting the sub-control unit 203 are not sufficient, the intermediate unit 202 receives the first and second authentications obtained from the received authentication data 303. Intermediate processing information 304 obtained by performing a relatively simple or low-level encryption operation on the result of authenticating the main control unit 201 a plurality of times using values is supplied to the sub-control unit 203.

  On the other hand, when the processing capacity of the CPU 203a constituting the sub-control unit 203 and the storage capacity of the ROM 203b constituting the sub-control unit 203 are sufficient, the intermediate unit 202 receives the first and second authentications obtained from the received authentication data 303. Intermediate processing information 304 obtained by performing a complicated or advanced re-encryption operation on the result of authenticating the main control unit 201 a plurality of times using the value is supplied to the sub-control unit 203.

  Furthermore, 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 or the like), the first authentication result, the second Even if a formal difference occurs in the data structure such as the authentication result or the intermediate calculation result, the main control unit 201 or the sub control unit 203 in which a program is changed or a difference occurs, and the intermediate unit 202 Can respond.

  The intermediate unit 202 performs authentication twice using the first and second authentication values described above, and transmits the authentication results (first and second authentication results) to the sub-control unit 203. The sub-control unit 203 Based on the transmitted first and second authentication results, 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 intermediate unit 202 to perform authentication using the first and second authentication values, data required for authentication (hereinafter referred to as “expected value” or the like) is stored in a storage unit such as the ROM 202b constituting the intermediate unit 202. Needless to say, must be stored in advance. 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, among the first and second authentication values, the program code inspection value varies the address range in which the program code in the ROM 201b of the main control unit 201 is stored in correspondence with the control command. Or processing methods for performing processing such as an error detection calculation for generating the authentication data 303 from the first and second authentication values.

  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 includes the control command data 301 and the accompanying data 302 itself, values obtained by performing the above-described processing on the control command data 301 and the accompanying data 302, and the like.

In general, an unauthorized control unit attempts to cause the sub-control unit 203 to perform an unauthorized operation by transmitting control command data different from 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 combines the data related to the control command data 301 and the accompanying data 302 and the first authentication value or the second authentication value. A process of generating authentication data 303 by encrypting may be performed.

  The authentication data 303 is generated by performing the above-mentioned “predetermined processing process”, the control command data 301 of the predetermined control command to which the authentication data 303 is added and the data generated by the “predetermined processing process” or the accompanying data. The data 302 may be generated by performing four arithmetic operations or logical operations.

  The timing at which the main control unit 201 generates the first and second authentication values and the timing at which the authentication data 303 is generated using the first and second authentication values are not particularly limited, and a predetermined control command In the control program of the main control unit 201, the process for generating the first and second authentication values and the first and second authentication values are used so that the control command data 301 is generated until the control command data 301 is transmitted. A program for performing processing for generating the authentication data 303 may be incorporated.

  In this embodiment, an example in which two first and second authentication values are used is shown, but the present invention is not limited to this. The number of authentication values is appropriately set in consideration of the program capacity for the main control unit 201 to create the authentication code, the processing capability such as the processing speed of the program, and the like. For example, when the processing capacity of the main control unit 201 is low, it is desirable to set the number of authentication values to about two or three. However, when the processing capacity is high, the number of authentication values is four. You may do it above. Further, the number of authentication values may be changed for each predetermined control command to which the authentication data 303 is added. In this way, if authentication is performed a plurality of times using a plurality of authentication values, for example, the processing capacity of the CPU configuring the main control unit 201 or the processing capacity of the CPU configuring the sub-control unit 203 is low, and high-level authentication is performed. Since processing cannot be performed, even when an authentication method with a light processing load is unavoidable, it is possible to improve security by performing authentication multiple times.

  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). The normal control signal 320 is supplied to the sub-control unit 203 as it is. On the other hand, when, for example, the 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 intermediate to the authentication data 303. Processing is performed to generate intermediate processing information 304, 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, 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. 11 and 12. The main control unit 201 has two different authentication values (first (Authentication value 1 and second authentication value) and the authentication data 303 is generated by processing using the first authentication value and the second authentication value 2 as an example. The transmission / reception process of the control signal between the main control unit 201 and the prize ball control unit 204 is 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 predetermined control command. When the determination result of step S62 is “YES”, that is, when the control command transmitted this time is a predetermined control command, the main control unit 201 proceeds to step S63. In step S63, the main control unit 201 sets the control command data 301 (control command data of a predetermined control command) 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 performs a process of generating a first authentication value, performs a process of storing the generated first authentication value in the RAM 201c, and then proceeds to step S65. Note that if the first authentication value is generated and stored in the RAM 201c before the process of step S64, it is not necessary to perform the process of generating the first authentication value.

In step S65, the main control unit 201 performs a process of generating a second authentication value, performs a process of storing the generated second authentication value in the RAM 201c, and then proceeds to step S66. Note that if the second authentication value is generated and stored in the RAM 201c before the process of step S65, it is not necessary to perform the process of generating the second authentication value.
Further, as described above, at least one of the first authentication value and the second authentication value, which are a plurality of authentication values generated in step S64 and step S65, is a predetermined program code stored in the ROM 201b. A process for generating an authentication value (program code inspection value) is performed.

  In step S66, the main control unit 201 performs predetermined processing using the first authentication value and the second authentication value generated in steps S64 and S65 described above, according to the processing program. And the process which memorize | stores the data obtained by performing this predetermined process in RAM201c as authentication data is performed. As the predetermined processing, as described above, for example, four arithmetic operations or logical operations using unencrypted or encrypted first and second authentication values are performed to have a predetermined data length. Processing to obtain operation data, processing to rearrange the bit array of operation data obtained by these four arithmetic operations or logical operations, processing to shift or rotate the bits of the operation data, or not encrypted or encrypted A process of taking out a plurality of bits constituting the first authentication value and the second authentication value and arranging them according to a predetermined rule to generate one data can be considered. Even when three or more different authentication values are generated and the authentication data 303 is generated by the processing using these generated authentication values, the same processing as the processing in steps S64 to S66 is performed.

  In the process of step S66, the generated authentication data 303 may be encrypted by a relatively simple encryption method such as Caesar cipher, single substitution cipher, or enigma. Further, the order of the process of step S63 and the process of steps S64 to S66 may be interchanged.

  In step S67, 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 S66 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 to be transmitted this time is not a predetermined control command, the main control unit 201 proceeds to step S68. In step S68, the main control unit 201 sets the control command data 301 (control command data of a control command other than the predetermined control command) and the accompanying data 302 in a predetermined storage area of the RAM 201c, and then proceeds to step S69. In step S69, the main control unit 201 generates a control signal (normal control signal) including the control command data 301 and the accompanying data 302 set in the processing of step S68 described above, and transmits the control signal to the intermediate unit 202. Terminate the process.

  In this way, the main control unit 201 adds the authentication data 303 to the control command data 301 only when transmitting control command data of a predetermined control command to the intermediate unit 202. Since the authentication process is performed only when control command data of a predetermined control command is transmitted, the rate at which the processing load of the main control unit 201 and the sub control unit 203 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 or not the authentication data 303 is included in the received control signal, but the control command data 301 included in the control signal is a predetermined control command. It may be determined whether it is control command data.

  In step S73, the intermediate unit 202 extracts the authentication data 303 from the control signal, performs intermediate processing on the authentication data 303, and then proceeds to step S74. As the intermediate process, among the processes (a) to (i) shown below, any one of the processes other than the authentication process (d) and the process (d) or a combination of these processes is used. Do.

(A) If the authentication data 303 is encrypted by the main control unit 201, it is decrypted.
(B) The first and second authentication values are restored from the authentication data 303 that is not encrypted by the main control unit 201 or decrypted by the process (a).
(C) When one or both of the first authentication value and the second authentication value restored in the processing of (b) is encrypted by the main control unit 201, it is decrypted.

  (D) The first authentication value restored by the process of (b) or restored by the process of (b) and decrypted by the process of (c) and restored by the process of (b) or (b) Using the second authentication value restored by the process (c) and decrypted by the process (c), authentication is performed twice as to whether or not the main control unit 201 is a regular main control unit.

  The authentication process twice in (d) is performed by the following method, for example. That is, for example, it is determined whether or not the first and second authentication values match the expected values corresponding to the first and second authentication values. Note that the intermediate unit 202 has a predetermined relationship between the first and second authentication values and the expected values corresponding to the first and second authentication values, not whether or not the first and second authentication values match the expected values corresponding to the first and second authentication values. It may be determined whether or not there is. The predetermined relationship refers to a relationship in which, for example, a value obtained by performing a predetermined calculation on the first and second authentication values matches an expected value corresponding to each of the first and second authentication values.

  The expected value used by the intermediate unit 202 for collation is stored in advance in a predetermined storage area of the ROM 202b constituting the intermediate unit 202, for example, at the time of manufacture. Note that the expected value used by the intermediate unit 202 for collation may be transmitted to the intermediate unit 202 from other components. As other constituent units, for example, the prize ball control unit 204 and a dedicated processing unit for generating expected values corresponding to the first and second authentication values (hereinafter referred to as “expected value calculation unit”). and so on. The expected value calculation unit may transmit each expected value stored in advance to the intermediate unit 202, or may generate each expected value for each matching process. Further, a coefficient necessary for calculating each expected value may be transmitted from an external device to the intermediate unit 202 or the expected value calculating unit via an external connection interface (not shown). In this way, if the expected values corresponding to the first and second authentication values are not stored in advance in the predetermined storage area of the ROM 202b configuring the intermediate unit 202, the information is acquired from the other components. The first and second authentication values can be changed afterwards.

(E) Either one or both of the first authentication result and the second authentication result obtained by the processing of (d) are encrypted.
(F) Encrypted or unencrypted first authentication result and encrypted or unencrypted second authentication result, for example, control command data 301 or accompanying data received together with the authentication data 303 302, either one or both of these, the control command data 301 or any one or both of the accompanying data 302 is converted based on a predetermined conversion formula, or the random number generated by the random number generator, etc. Intermediate operations such as four arithmetic operations and logical operations are performed with respect to the predetermined numerical values.

(G) Encrypt or re-encrypt any of the encrypted first authentication result, the encrypted second authentication result, and the intermediate operation result.
(H) A predetermined processing process is performed on two or more pieces of data among intermediate processing results, such as first authentication results, second authentication results, and the like.

(I) The processing data is encrypted.
(J) A control signal with intermediate processing information is generated by adding intermediate processing information obtained by the processing (a) to (i) described above or a combination of these processing to the control command data and accompanying data. To do. The intermediate processing information includes, for example, at least one of unencrypted or encrypted processing data such as a first authentication result, a second authentication result, and an intermediate calculation result.

  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 the control command data 301 to be processed is control command data of a predetermined control command 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 processing for extracting information from the intermediate processing information 304, and then proceeds to step S84. As the information extraction process from the intermediate process information 304, for example, the following processes [1] to [3] or a combination of these processes are performed.

[1] When any of the processing data such as the first authentication result, the second authentication result, the intermediate operation result, etc. constituting the intermediate processing information 304 is encrypted or re-encrypted Decrypt.
[2] From the processed data that is not encrypted or decrypted in the process [1], such as intermediate operation results that are not encrypted or decrypted in the process [1], the first and second Retrieve the authentication result.
[3] When the first authentication result or the second authentication result extracted in the process of [2] is encrypted or re-encrypted, it is decrypted.

  In step S84, the sub-control unit 203 determines whether or not both the first authentication result and the second authentication result obtained in the process of step S83 indicate that the authentication has succeeded. If the determination result in step S84 is “YES”, that is, if both the first authentication result and the second authentication result obtained in the process of step S83 indicate that the authentication has succeeded, the sub-control unit In step 203, the process 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 either the first authentication result or the second authentication result obtained in the process of 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, when the employee of the game shop passes in front of the pachinko gaming machine 1, the employee only needs to be aware of the state. 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 processing sequences shown in FIGS. When the control command data 301 is control command data of a control command other than the predetermined control 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 (step S91 in FIG. 14). Then, go 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. As described above, when the control command data 301 is control command data of a control command other than the predetermined control command, the intermediate unit 202 performs the received control command data 301 and associated data 302 without performing intermediate processing. The normal control signal 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. I do.

  On the other hand, when the control command data 301 is control command data of a predetermined control 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 S101 in FIG. 15). ) Then, the process proceeds to step S102. In step S102, the main control unit 201 performs a process of generating a first authentication value, stores the generated first authentication value in the RAM 201c, and then proceeds to step S103. Note that, when the first authentication value is generated and stored in the RAM 201c before the process of step S102, it is not necessary to perform the process of generating the first authentication value.

  In step S103, the main control unit 201 performs a process of generating a second authentication value, stores the generated second authentication value in the RAM 201c, and then proceeds to step S104. If the second authentication value is generated and stored in the RAM 201c before the process of step S103, it is not necessary to perform the process for generating the second authentication value.

  In step S104, the main control unit 201 performs a predetermined processing using the first authentication value and the second authentication value generated in the processing of step S102 and step S103 according to the processing program. Then, after performing processing for storing the data obtained by performing this processing in the RAM 201c as the authentication data 303, the process proceeds to step S105. The method for performing the predetermined processing is as described above, and the description thereof is omitted.

  In step S <b> 105, 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, after receiving the control signal with authentication data transmitted in the process of step S105 (see step S106), the intermediate unit 202 proceeds to step S107. In step S107, the intermediate unit 202 performs the above-described intermediate processing on the authentication data 303 included in the control signal with authentication data, and then proceeds to step S108.

  In step S108, 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 S107. A signal is generated and transmitted to the sub-control unit 203.

Accordingly, the sub control unit 203 receives the control signal with intermediate processing information transmitted in the process of step S108 (see step S109), and then proceeds to step S110. In step S110, the sub-control unit 203 extracts the intermediate processing information 304 from the control signal, performs processing for extracting information from the intermediate processing information 304, and then proceeds to step S111.
In step S111, the sub control unit 203 determines whether or not both the first authentication result and the second authentication result obtained in the process of step S110 indicate that the authentication has succeeded. If the determination result in step S111 is “YES”, that is, if both the first authentication result and the second authentication result obtained in the process of step S110 indicate that the authentication has succeeded, the sub-control unit In step 203, the process proceeds to step S112. In step S <b> 112, 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 S111 is “NO”, that is, if either the first authentication result or the second authentication result obtained in the process of step S110 does not indicate that the authentication is successful, If the authentication is not successful, the sub control unit 203 proceeds to step S113. In step S <b> 113, 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 on the authentication data 303 not at every reception of the authentication data 303 but at a time when a plurality of authentication data 303 is received. In this case, for example, if the intermediate unit 202 receives the control signal with authentication data including the control command data of the predetermined control command, the accompanying data, and the authentication data for the first time, the intermediate control unit 202 does not perform the intermediate process and performs the sub control unit as it is. 203. When the intermediate unit 202 receives the control signal with authentication data including the control command data of the predetermined control command, the accompanying data, and the authentication data for the second time, the intermediate unit 202 performs intermediate processing on the authentication data 303 received for the first time. At this time, the intermediate unit 202 may perform intermediate processing on both the authentication data 303 received first time and the authentication data 303 received second time. In this way, if intermediate processing is performed when a plurality of pieces of authentication data 303 are received, the risk of erroneously performing intermediate processing, such as when extra data is added to the control signal due to an error, is reduced. Can be made. The same applies to the information extraction processing in the sub-control unit 203.

  As described above, in the pachinko gaming machine 1 according to the present embodiment, when the main control unit 201 transmits control command data of a predetermined control command, the first for authenticating the validity of the main control unit 201. The second authentication value is generated, and predetermined processing is performed on these to generate authentication data having a predetermined data length, which is then transmitted to the intermediate unit 202, and so-called "no processing" is performed. The “bare data” is not transmitted to the intermediate unit 202 as it is. Further, the intermediate unit 202 performs two authentication processes using the first and second authentication values. For this reason, the following fraud can be detected. Further, if the authentication data 303 including the control command data 301 and the accompanying data 302 to be 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 is more reliably 1 can detect fraudulent acts.

(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.

  In the pachinko gaming machine 1 according to the present embodiment, when the main control unit 201 transmits control command data of a predetermined control command to the sub control unit 203, the intermediate unit 202 confirms the validity of the main control unit 201. An intermediate process including two authentication processes for authentication is performed. Therefore, for example, by changing only the timing design during the jackpot state, it is possible to cause the existing pachinko gaming machine 1 to execute the authentication process. Further, the processing load on the main control unit 201 and the sub control unit 203 increases by performing the authentication process, for example, only during a period in which the jackpot command data is transmitted (period in which the jackpot state is in effect). The rate at which the processing load of the unit 201 and the sub-control unit 203 increases can be suppressed.

  In the pachinko gaming machine 1 according to the present embodiment, when the control command data included in the control signal transmitted from the main control unit 201 is control command data of a predetermined control command, the control command data 301 and the accompanying data Since the authentication data 303 is added to 302, an increase in communication load between the main control unit 201 and the sub control unit 203 can be suppressed as compared with the case where the authentication data 303 is transmitted alone. Further, by including the authentication data 303 in the control signal, it is possible to reduce the risk that the authentication data 303 is extracted from the communication data and analyzed as compared with the case where the authentication data 303 is transmitted alone. .

  In the pachinko gaming machine 1 according to the present embodiment, the main control unit 201 obtains the authentication data 303 from the first and second authentication values for authenticating the main control unit 201 twice, and then the authentication data 303 is supplied to the intermediate section 202. Therefore, the possibility that each authentication value is analyzed by an unauthorized person can be reduced as compared with a case where an authentication value that has not been subjected to any processing is supplied to the intermediate unit 202 as it is. In addition, when the first authentication value or the second authentication value is generated using a predetermined program code, the main control unit 201 more accurately detects fraud due to falsification of the program executed by the main control unit 201. And the validity of the program code can be authenticated.

  Furthermore, in the pachinko gaming machine 1 according to the present embodiment, the main control unit 201 supplies the authentication data 303 obtained from the first and second authentication values for authenticating the main control unit 201 twice to the intermediate unit 202. Therefore, compared with the case where a plurality of authentication values are individually supplied to the intermediate unit 202, the number of transmissions and the amount of data can be reduced. Thereby, it is possible to suppress an increase in load on data communication of the main control unit 201, the intermediate unit 202, and the sub control unit 203.

  Further, in the pachinko gaming machine 1 according to the present embodiment, since the authentication process is executed only by the intermediate unit 202, the sub-control unit is compared with the case where only the sub-control unit 203 executes the authentication process multiple times. The processing load of the CPU 203a constituting the 203 does not increase. For this reason, the processing speed of the sub-control unit 203 is not reduced, and there is no inconvenience such as display for production not being performed smoothly.

  Since the authentication data 303 and the intermediate processing information 304 are added only to the predetermined control command, the authentication result obtained from the intermediate processing information 304 added to the predetermined control command is added to the program executed by the sub-control unit 203. It is only necessary to add processing according to. Therefore, since it is not necessary to design a new timing for the entire program executed by the sub-control unit 203, the processing according to the authentication result is compared with the case where authentication data and intermediate processing information are added to all control commands. Designing the timing to add the function, implementing the function, verifying the function, etc. can be realized more easily and with less work man-hours.

  In addition, since only the intermediate unit 202 executes the authentication process, the authentication process can be separated from the process executed by the sub-control unit 203. For example, an algorithm for encrypting an authentication process, an authentication data, or the like (Hereinafter collectively referred to as “authentication algorithm”), and when the version is upgraded, it is easier to handle with fewer man-hours than when the sub-control unit 203 executes the authentication process. Can do. Further, even with the same model of the pachinko gaming machine 1, it is possible to easily implement different authentication algorithms. As a result, the risk that the authentication data is analyzed can be reduced.

  In addition, since the intermediate unit 202 that executes the authentication process and the sub-control unit 203 that mainly executes the effect process are independent of each other, the authentication program and the effect program can be designed separately. Therefore, 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.

  Furthermore, according to the present embodiment, since only the intermediate unit 202 executes the authentication process, the processing capacity of the CPU 203a constituting the sub-control unit 203, the storage capacity of the ROM 203b constituting the sub-control unit 203, or the sub-control unit The authentication algorithm can be designed without being affected by the design constraints of 203, and the addition of the authentication function can be realized more easily. In addition, a method (for example, a result of two-time authentication that the intermediate unit 202 supplies to the sub-control unit 203 according to the processing capability of the CPU 203a configuring the sub-control unit 203 and the storage capacity of the ROM 203b configuring the sub-control unit 203 (for example, , Data structure etc.) can be designed easily.

  For example, if the processing capacity of the CPU 203 a constituting the sub-control unit 203 and the storage capacity of the ROM 203 b constituting the sub-control unit 203 are not sufficient, the intermediate unit 202 receives the first and second authentications obtained from the received authentication data 303. Intermediate processing information obtained by performing relatively simple or low-level encryption operation on the result of authenticating the main control unit 201 a plurality of times using the value is supplied to the sub-control unit 203.

  On the other hand, when the processing capacity of the CPU 203a constituting the sub-control unit 203 and the storage capacity of the ROM 203b constituting the sub-control unit 203 are sufficient, the intermediate unit 202 receives the first and second authentications obtained from the received authentication data 303. Intermediate processing information obtained by performing a complex or advanced re-encryption operation on the result of authenticating the main control unit 201 a plurality of times using values is supplied to the sub-control unit 203.

  Furthermore, 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 or the like), the first authentication result, the second Even if a formal difference occurs in the data structure such as the authentication result or the intermediate calculation result, the main control unit 201 or the sub control unit 203 in which a program is changed or a difference occurs, and the intermediate unit 202 Can respond.

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 the above-described embodiment, 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 thereto, and the main control unit 201 and the prize ball control unit 204 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.

  In the above embodiment, the intermediate unit 202 authenticates the main control unit 201 twice. However, the present invention is not limited to this, and the intermediate unit 202 authenticates the main control unit 201 three times or more. You may comprise so that it may do.

  In the above-described embodiment, the intermediate unit 202 adds intermediate processing information 304 including the first authentication result, the second authentication result, and the like to the control command data 301 and the accompanying data 302. Although the example which transmits a signal to the sub-control part 203 was shown, it is not limited to this. For example, the intermediate unit 202 may transmit the intermediate processing information 304 including at least the first authentication result and the second authentication result to the sub-control unit 203 in two steps. If comprised in this way, it can suppress that a fraudulent person grasps | ascertains all the data compared with above-described embodiment. Furthermore, compared with the above-described embodiment, the transmission method of the first authentication result and the second authentication result and the timing design for adding the authentication function, the implementation of the function, and the verification of the function are simpler and less. It can be realized with work man-hours.

  Further, in the above-described embodiment, an example in which the present invention is applied to the pachinko gaming machine 1 has been shown. However, the present invention is not limited thereto, and the present invention is not limited to pachinko gaming machines such as sparrow ball gaming machines and arrangement balls. The present invention can also be applied to other game machines such as a ball game machine and a slot machine such as a slot machine. Even in these gaming machines, the same effects as in the above embodiment can be obtained by configuring in the same manner as in the above embodiment.
