(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.

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 machine, the main control unit, when the control command transmitted to the peripheral part is a jackpot start command for starting the jackpot state processing or a jackpot end command for ending the jackpot state processing, Authentication data for authenticating the control unit is added to the jackpot start command or jackpot end command and transmitted to the peripheral unit. When the peripheral unit receives the jackpot start command or jackpot end command, the peripheral unit authenticates the main control unit based on the authentication data transmitted in addition to the jackpot start command or jackpot end command (see, for example, Patent Document 3). .) Hereinafter, this technique is referred to as a third conventional example.

  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, when the peripheral CPU executes the authentication process in addition to the existing game process, the authentication data is added to the jackpot start command. Even if it is 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, or it is difficult to add the authentication process itself. It is conceivable that a design constraint occurs. In recent years, in particular, in order to improve the interest of the game, there is a tendency for various effects to appeal to the visual and auditory sense of the player regarding the control of the variation of the pattern. Therefore, it is desirable to construct a gaming machine provided with an authentication unit that reduces the load of performing an authentication process on a peripheral 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.

  An authentication program according to an invention described in claim 17 causes a computer to realize the function described in any one of claims 12 to 16.

  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 obtains at least one authentication data from the intermediate unit and the peripheral unit. To supply. 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 as it is to the intermediate part and the peripheral part. 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.

  Furthermore, according to the present invention, 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 and the peripheral unit. Compared to the case where authentication values are individually supplied to the intermediate part and the peripheral part, the number of transmissions and the amount of data can be reduced. 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 separately for the intermediate part and the peripheral part, the CPU of the CPU constituting the peripheral part is compared with the case where only the peripheral part executes the authentication process multiple times. The rate at which the processing load increases can be suppressed. For this reason, it is possible to minimize the possibility of inconveniences such as the processing speed of the peripheral portion being reduced and the display for production not being performed smoothly.

  Further, since the authentication data is added only to the jackpot start command or jackpot end command, it is only necessary to add an authentication process related to the jackpot start command or jackpot end command to the program executed by the peripheral portion. Therefore, there is no need to design a new timing for the entire program executed by the peripheral part. Compared to the case where authentication data is added to all control commands, the timing design and function implementation to add the authentication function. It can be realized more easily and with less work man-hours such as function verification.

  Further, according to the present invention, since the intermediate unit executes at least the first authentication process, the peripheral unit executes the authentication process compared to a gaming machine in which only the peripheral unit executes a plurality of authentication processes. Since the configuration of the program and the program for predetermined processing becomes relatively simple, it becomes easy to maintain consistency with other functions. In addition, even if the predetermined processing executed by the peripheral unit is different for each gaming machine model, the authentication processing performed by the peripheral unit can be shared, so the entire gaming machine for each gaming machine model can be shared. Program design is easy, design time can be reduced, and work efficiency is improved.

  Furthermore, according to the present invention, since at least the first authentication process is executed by the intermediate unit, it is simpler and requires less work man-hours than a gaming machine in which only the peripheral unit executes a plurality of authentication processes. The authentication algorithm in the authentication program executed by the unit can be changed. In addition, even with the same model, it is possible to easily adopt a different authentication algorithm. Thereby, the danger that authentication data will be analyzed can be reduced.

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

  Furthermore, according to the present invention, since the intermediate part is provided between the main control part and the peripheral part, there is a difference in processing capability between the CPU constituting the main control part and the CPU constituting the peripheral part. Even if there is a difference in storage capacity between the ROM configuring the main control unit and the ROM configuring the peripheral unit, the difference can be absorbed in the intermediate unit.

  For example, if the processing capacity of the CPU that constitutes the main control unit has a margin compared to the processing capacity of the CPU that constitutes the peripheral part, the main control unit can obtain a plurality of authentication values by processing them in a complicated or advanced manner. The intermediate unit supplies the authentication data to the intermediate unit, and the intermediate unit uses the authentication value for authenticating the main control unit at least once among the plurality of authentication values obtained from the received authentication data. Intermediate processing information obtained by processing the result of one-time authentication and other authentication values by a relatively simple method is supplied to the peripheral portion.

  In addition, when the storage capacity of the ROM that constitutes the peripheral part is larger than the storage capacity of the ROM that constitutes the main control part, the main control part can obtain a plurality of authentication values by a relatively simple method. The intermediate unit supplies the authentication data to the intermediate unit, and the intermediate unit uses the authentication value for authenticating the main control unit at least once among the plurality of authentication values obtained from the received authentication data. Intermediate processing information obtained by processing the result of one-time authentication and other authentication values by a complicated or advanced technique is supplied to the peripheral portion.

  This is not only the case in which there is a difference in the processing capacity of the CPU that constitutes the main control unit and the peripheral part and the storage capacity of the ROM, but there is no difference between these, but the CPU that constitutes the main control unit Or, when all or part of one of the programs executed by the CPUs constituting the peripheral part is changed (such as version upgrade), or in the data structure of the data to be communicated, the main control part and the peripheral part The same applies to cases where there is a formal difference.

  Further, according to the present invention, the jackpot start command and the jackpot end command are control commands for starting or ending the jackpot state, and since the transmission frequency is low compared to other control commands, the authentication data is included in the control signal. The risk of being extracted can be reduced. In addition, even if authentication data is extracted from the control signal, the number of samples that can be acquired is small, so that the risk that the authentication data is analyzed can be reduced. Furthermore, since the authentication process is performed only when the jackpot start command or jackpot end command is transmitted, it is possible to suppress the rate at which the processing load on the main control unit and the peripheral section increases due to the authentication process.

Below the symbol display unit 104, a first start port 105 capable of receiving a game ball driven toward the game area 103 is disposed. A second start port 120 is disposed below the first start port 105. When the pair of movable pieces (not shown) is in the closed state, the second starter port 120 is unable to accept the game ball or is difficult to accept, and when the pair of movable pieces is in the open state. The game ball can be received more easily than the first starting port 105.

  A winning gate 106 is arranged on the left side of the symbol display unit 104. The winning gate 106 is provided to detect the passing of a game ball and to draw a normal symbol for opening the second start port 120 for a predetermined time. A plurality of normal winning holes 107 are arranged on the left side or the lower side of the symbol display unit 104. When a game ball enters each normal winning port 107, a predetermined number of winning balls (for example, 10) is paid out. At the bottom of the game area 103, a collection port 108 is provided for collecting game balls that have not entered any of the entrances.

[6] 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 authentication 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.

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 as an example of the transmission timing of the jackpot related command (the jackpot reach command, the jackpot start command, the jackpot command, the jackpot end command). The jackpot reach command shown in FIG. 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. Also, the jackpot end command shown in FIG. 5 (4) is transmitted only once when all rounds of the jackpot state are completed and the normal state is entered.

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

[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 off-reach 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 the first authentication using the first authentication value obtained from the authentication data acquired from the main control unit 201, and decrypts, encrypts, the first authentication result or the second authentication value. 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 the second authentication using the second authentication value obtained from the intermediate processing information acquired from the intermediate unit 202, and the first authentication result or the second obtained from the intermediate processing information. Processing according to at least one of the authentication results is performed. Here, the predetermined control command specifically refers to a jackpot start command for starting the jackpot state processing or a jackpot end command for ending the jackpot state processing.

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

  On the other hand, when the control command data 301 in the control signal is data specific to the jackpot start command and jackpot end command, as shown in FIG. 9 (2), the main control unit 201 controls the control command data 301 and accompanying data. In addition to 302, an authentication data-added control signal 310 including 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 start command data or jackpot end command data, the authentication data 303 may be added at the time of the third control signal transmission.

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

  Further, 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 and the sub control unit 203. is doing. Therefore, the possibility that each authentication value is analyzed by an unauthorized person can be reduced as compared with the case where an authentication value that has not been subjected to any processing is supplied to the intermediate unit 202 and the sub-control unit 203 as they are. In addition, when the main control unit 201 generates the first and second authentication values using a predetermined program code, the main control unit 201 can more accurately detect an illegal act caused by falsification of the program executed by the main control unit 201. It is possible to authenticate the correctness of the program code.

  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 and the sub control unit 203, a plurality of Compared to the case where authentication values are individually supplied to the intermediate unit 202 and the sub-control unit 203, 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, since the authentication process is executed twice by the intermediate unit 202 and the sub-control unit 203, the sub-control unit 203 is compared with a case where only the sub-control unit 203 executes the authentication process a plurality of times. The rate at which the processing load of the CPU 203a to be configured increases can be suppressed. For this reason, the processing speed of the sub-control unit 203 is reduced, and it is possible to minimize the possibility of inconveniences such as the display for rendering not being performed smoothly.

  Further, since the authentication process is executed twice by the intermediate unit 202 and the sub-control unit 203, the pachinko machine caused by fraudulent acts on the main control unit 201 such as the above (1) to (3), noise, etc. In addition to malfunctions of the gaming machine 1, malfunctions of the pachinko gaming machine 1 caused by fraud and noise similar to the above (1) to (3) with respect to the intermediate unit 202 can be prevented, and security can be improved. Can be planned.

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

  Further, since the intermediate unit 202 is provided between the main control unit 201 and the sub control unit 203, there is a difference in processing capability between the CPU 201a configuring the main control unit 201 and the CPU 203a configuring the sub control unit 203. Even if there is a difference in storage capacity between the ROM 201b constituting the main control unit 201 and the ROM 203b constituting the sub control unit 203, the difference can be absorbed by the intermediate unit 202.

  For example, when the processing capacity of the CPU 201a configuring the main control unit 201 has a margin as compared with the processing capacity of the CPU 203a configuring the sub-control unit 203, the main control unit 201 determines whether the first authentication value, the second authentication value, or the authentication Authentication data 303 obtained by performing a complicated or advanced encryption operation on any of the data is supplied to the intermediate unit 202, and the intermediate unit 202 is relatively simple or low in response to the received authentication data 303. The result of the encryption operation obtained by performing the encryption operation is supplied to the sub-control unit 203.

  Further, when the storage capacity of the ROM 203b constituting the sub-control unit 203 has a margin as compared with the storage capacity of the ROM 201b constituting the main control unit 201, the main control unit 201 keeps the authentication data 303 as it is or is relatively simple or low. The encryption operation result obtained by performing repeated encryption operations is supplied to the intermediate unit 202, and the intermediate unit 202 performs a complicated or advanced re-encryption operation on the received encryption operation result, An intermediate operation result obtained by performing an intermediate operation such as performing a more complicated or advanced re-encryption operation after decrypting the encryption operation result is supplied to the sub-control unit 203.

  This is not only the case where there is a difference in the processing capacity of the CPUs 201a and 203a and the storage capacities of the ROMs 201b and 203b constituting the main control unit 201 and the sub control unit 203, respectively, but there is no such difference. When one or all of the programs executed by the CPU 201a constituting the main control unit 201 or the CPU 203a constituting the sub-control unit 203 are changed (for example, version upgrade), the first authentication value, the second authentication The same applies to a case where a formal difference occurs in a data structure such as a value or an intermediate operation result.

  In addition, since the intermediate unit 202 executes the first authentication process, the sub control unit 203 is simpler and requires less work man-hours than a gaming machine in which only the sub control unit 203 executes a plurality of authentication processes. The authentication algorithm in the authentication program to be executed can be changed.

  The intermediate unit 202 performs the first authentication using the first authentication value described above, transmits the authentication result (first authentication result) and the second authentication value to the sub-control unit 203, and the sub-control unit 203 described above. By performing the second authentication using the second authentication value, the sub-control unit 203 outputs the control signal output source based on the obtained authentication result (second authentication result) and the transmitted first authentication result. It is possible to determine whether or not is a normal main control unit 201 and whether it is a normal intermediate unit 202 or not. Note that in order for the intermediate unit 202 and the sub-control unit 203 to perform authentication using the first and second authentication values, data (such as a ROM) that configures the intermediate unit 202 and the sub-control unit 203 requires data (for authentication). Hereinafter, it is needless to say that “expected value” or the like) needs to 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, the 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 described above.

  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”, and the control command data of the jackpot start command or jackpot end command to which the authentication data 303 is added and the data generated by this “predetermined processing” 301 or the accompanying 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 the jackpot start command or A process of generating first and second authentication values in the control program of the main control unit 201, and first and second authentication values so that the control command data 301 of the jackpot end command is generated before being transmitted. It is only necessary to incorporate a program for performing the process of generating the authentication data 303 using.

  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 jackpot start command or jackpot end 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 capability of the CPU 201a constituting the main control unit 201 or the processing capability of the CPU 203a constituting 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 the control command transmitted this time is a jackpot start command or a jackpot end command. If the determination result in step S62 is “YES”, that is, if the control command transmitted this time is a jackpot start command or a jackpot end command, the main control unit 201 proceeds to step S63. In step S63, the main control unit 201 sets the control command data 301 (the jackpot start command data or jackpot end command data) and the accompanying data 302 in a predetermined storage area of the RAM 201c, and then proceeds to step S64.

  In step S64, the main control unit 201 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 neither a jackpot start command nor a jackpot end 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 for control commands other than the jackpot start command and jackpot end command) and the accompanying data 302 in a predetermined storage area of the RAM 201c, and then proceeds to step S69. move on. 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.

As described above, the main control unit 201 adds the authentication data 303 to the control command data 301 only when the jackpot start command data or jackpot end command data is transmitted to the intermediate unit 202. The jackpot start command and jackpot end command are control commands for starting or ending the jackpot state, and have a lower transmission frequency than other control commands. Therefore, the risk that the authentication data 303 is extracted from the control signal can be reduced. Further, even if the authentication data 303 is extracted from the control signal, the number of samples that can be acquired is small, so that the risk of the authentication data 303 being analyzed can be reduced.
Since the authentication process is performed only when the jackpot start command data or jackpot end command data is transmitted, the rate at which the processing load of the main control unit 201 or 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 the authentication data 303 is included in the received control signal, but the control command data 301 included in the control signal is the jackpot start command data or It may be determined whether it is jackpot end 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 (j) 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 main control unit 201 is a regular main control unit using the first authentication value restored in the process of (b) or restored in the process of (b) and decrypted in the process of (c). The first authentication process is performed as to whether or not there is.
The first authentication process in (d) is performed by the following method, for example. That is, for example, it is determined whether or not the first authentication value matches the expected value. Note that the intermediate unit 202 may determine whether the first authentication value and the expected value are in a predetermined relationship instead of whether or not the first authentication value and the expected value match. The predetermined relationship means, for example, a relationship in which a value obtained by performing a predetermined calculation on the first authentication value matches an expected value.

  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. Examples of other components include a prize ball control unit 204 and a dedicated processing unit (hereinafter referred to as an “expected value calculation unit”) for generating the expected value of the first authentication value. The expected value calculation unit may transmit an expected value stored in advance to the intermediate unit 202, or may generate an expected value for each matching process. In addition, a coefficient necessary for calculating an expected value may be transmitted from an external device to the intermediate unit 202 or the expected value calculation unit via an external connection interface (not shown). As described above, if the expected value of the first authentication value is not stored in advance in the predetermined storage area of the ROM 202b configuring the intermediate unit 202, the first authentication value is obtained after the acquisition. Can be changed automatically.

(E) The first authentication result obtained by the process (d) or the second authentication value restored by the process (b) or restored by the process (b) and decrypted by the process (c). Either or both are encrypted.
(F) The first authentication result encrypted or not encrypted, the second authentication value encrypted or not encrypted, and the control command data 301 or the accompanying data 302 received together with the authentication data 303 Either one or both, conversion control command data obtained by converting one or both of the control command data 301 or the accompanying data 302 based on a predetermined conversion formula, or a predetermined random number generated by a random number generator Perform intermediate operations such as four arithmetic operations and logical operations on the numerical values of.

(G) If there is a formal difference in the data structure such as the first authentication result, the second authentication value, or the intermediate calculation result, the data structure conversion process is performed.
(H) Encrypt or re-encrypt any of the encrypted first authentication result, the encrypted second authentication value, and the intermediate operation result.
(I) A predetermined processing process is performed on two or more pieces of data among intermediate processing results such as the first authentication result, the second authentication value, and the like.
(J) Encrypt the processed data.
(K) A control signal with intermediate process information is generated by adding intermediate process information obtained by the processes (a) to (j) described above or a combination of these processes 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 value, 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 jackpot start command data or jackpot end command data set in advance for performing the authentication process.

  In step S83, the sub-control unit 203 extracts the intermediate processing information 304 from the control signal, performs the second authentication process, and then proceeds to step S84. As the second authentication process, for example, the following processes [1] to [4] or a combination of these processes is performed.

[1] When any of the processing data such as the first authentication result or the like, the second authentication value, or the intermediate calculation result 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 an intermediate operation result that is not encrypted or decrypted in the process [1], the first authentication result and The second authentication value is extracted.

[3] When the first authentication result or the second authentication value extracted in the processing of [2] is encrypted or re-encrypted, it is decrypted.
[4] Using the second authentication value obtained in any one of the processes [1] to [3], whether or not the main control unit 201 is a regular main control unit or whether the intermediate unit 202 is a regular subordinate The second authentication is performed for either or both of the control unit and the control unit.

  The authentication process in [4] is performed by the following method, for example. That is, for example, it is determined whether or not the second authentication value obtained by any one of the processes [1] to [3] matches the expected value. Note that the sub-control unit 203 may determine whether or not the second authentication value and the expected value have a predetermined relationship instead of whether or not the second authentication value and the expected value match. The predetermined relationship means, for example, a relationship in which a value obtained by performing a predetermined calculation on the second authentication value matches an expected value.

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

  In step S84, the sub-control unit 203 determines whether or not 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 processing based on the control command data 301 and the accompanying data 302, and then ends a series of processing. 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 relating to 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 there is a risk of fraudulent behavior under conditions different from other states during jackpots or during 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 jackpot start command and jackpot end 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 (FIG. 14). Step S91), the process proceeds to step S92. In step S <b> 92, the main control unit 201 generates a normal control signal including the control command data 301 and the accompanying data 302 and transmits it to the intermediate unit 202.

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

  On the other hand, when the control command data 301 is jackpot start command data or jackpot end command data, the main control unit 201 sets the control command data 301 and the accompanying data 302 in a predetermined storage area of the RAM 201c (step S101 in FIG. 15). Then, go 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 the second authentication process, obtains the result (second authentication result), 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, when the intermediate unit 202 receives the control signal with authentication data including the jackpot start command data or the jackpot end command data, the accompanying data and the authentication data for the first time, for example, the intermediate unit 202 performs the sub-control without performing the intermediate processing. To the unit 203. Then, when the middle unit 202 receives the control signal with authentication data including the jackpot start command data or jackpot end command data, the accompanying data and the authentication data for the second time, the intermediate unit 202 performs an intermediate process 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 authentication process 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 the jackpot start command data or the jackpot end command data, the first control for authenticating the validity of the main control unit 201 is performed. The first and second authentication values are 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 is not subjected to any processing. “Nude data” is not transmitted to the intermediate unit 202 as it is. Further, the intermediate unit 202 and the sub-control unit 203 perform authentication processing twice 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) 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 described in (2) above with an unauthorized substrate (spoofed substrate) provided between the main control substrate 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. Execution of a control command corresponding to the control command data can also be prevented.

  Further, in the pachinko gaming machine 1 according to the present embodiment, when the main control unit 201 transmits jackpot start command data or jackpot end command data to the sub control unit 203, the validity of the main control unit 201 in the intermediate unit 202 Intermediate processing including the first authentication processing is performed, and the second control processing is performed in the sub-control unit 203 to authenticate the validity of the main control unit 201 and the intermediate unit 202. The jackpot start command and jackpot end command are control commands for starting or ending the jackpot state, and have a lower transmission frequency than other control commands. Therefore, the risk that the authentication data is extracted from the control signal can be reduced. In addition, even if authentication data is extracted from the control signal, the number of samples that can be acquired is small, so that the risk that the authentication data is analyzed can be reduced. Further, the processing load on the main control unit 201 and the sub control unit 203 increases by performing the authentication process only during the period when the jackpot start command data or jackpot end command data is transmitted. The rate at which the processing load of 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 jackpot start command data or jackpot end command data, the control command data 301 and the accompanying command data are included. Since the authentication data 303 is added to the data 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 unit 202 and the sub-control unit 203. Therefore, the possibility that each authentication value is analyzed by an unauthorized person can be reduced as compared with the case where an authentication value that has not been subjected to any processing is supplied to the intermediate unit 202 and the sub-control unit 203 as they are. In addition, when the main control unit 201 generates the first and second authentication values using a predetermined program code, the main control unit 201 can more accurately detect an illegal act caused by falsification of the program executed by the main control unit 201. It becomes possible.

  Further, in the pachinko gaming machine 1 according to the present embodiment, the main control unit 201 obtains the authentication data 303 obtained from the first and second authentication values for authenticating the main control unit 201 twice and the intermediate unit 202 and the subordinate Since it supplies to the control part 203, compared with the case where a some authentication value is supplied to the intermediate | middle part 202 and the sub control part 203 separately, the frequency | count of transmission and its data amount can be decreased. 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, the authentication process is separately executed by the intermediate unit 202 and the sub-control unit 203, and therefore, only when the sub-control unit 203 executes a plurality of authentication processes. In comparison, the rate at which the processing load of the CPU 203a configuring the sub-control unit 203 increases can be suppressed. For this reason, the processing speed of the sub-control unit 203 is reduced, and it is possible to minimize the possibility of inconveniences such as the display for rendering not being performed smoothly.

  Furthermore, in the pachinko gaming machine 1 according to the present embodiment, the authentication process is separately executed by the intermediate unit 202 and the sub-control unit 203, so that the main control unit 201 such as (1) to (3) described above is executed. In addition to the malfunction of the pachinko gaming machine 1 due to fraud and noise, etc., the malfunction of the pachinko machine 1 due to the fraud and noise similar to the above (1) to (3) with respect to the intermediate portion 202 is prevented. Security can be improved.

  Further, since the authentication data 303 is added only to the control command data 301 of the jackpot start command or jackpot end command, the program executed by the sub-control unit 203 performs authentication processing for processing related to the jackpot start command or jackpot end command set in advance. Just add. Accordingly, since it is not necessary to design a new timing for the entire program executed by the sub-control unit 203, an authentication function is added compared to the case where the authentication data 303 is added to the control command data 301 of all control commands. Designing timing, implementing functions, verifying functions, etc. can be achieved more easily and with less work man-hours.

  Further, in the pachinko gaming machine 1 according to the present embodiment, since the intermediate unit 202 executes the first authentication process, the subordinate control unit 203 performs a plurality of times of authentication processing as compared to the gaming machine in which only the sub control unit 203 executes.

Even if the presentation process executed by the sub-control unit 203 is different for each model of the pachinko gaming machine 1, the authentication process executed by the sub-control unit 203 can be shared. Program design of the entire pachinko gaming machine 1 for each model is easy, design time can be shortened, and work efficiency is improved.

  Furthermore, in the pachinko gaming machine 1 according to the present embodiment, since the intermediate unit 202 executes the first authentication process, more than the gaming machine in which only the sub-control unit 203 executes a plurality of authentication processes. The authentication algorithm in the authentication program executed by the sub control unit 203 can be easily changed with a small number of work steps. In addition, even with the same model, it is possible to easily adopt a different authentication algorithm. Thereby, the danger that authentication data will be analyzed can be reduced.

  Further, according to the present embodiment, since the intermediate unit 202 is provided between the main control unit 201 and the sub control unit 203, the CPU 201a configuring the main control unit 201 and the CPU 203a configuring the sub control unit 203 Even if there is a difference in storage capacity between the ROM 201b constituting the main control unit 201 and a ROM 203b constituting the sub control unit 203, the difference is Can be absorbed.

  For example, when the processing capacity of the CPU 201a configuring the main control unit 201 has a margin as compared with the processing capacity of the CPU 203a configuring the sub-control unit 203, the main control unit 201 is one of the first and second authentication values. Alternatively, the authentication data 303 obtained by performing a complicated or advanced encryption operation on both is supplied to the intermediate unit 202, and the intermediate unit 202 uses the first authentication value obtained from the received authentication data 303. Intermediate processing information obtained by processing the first authentication result obtained by authenticating the main control unit 201 once and the second authentication value by a relatively simple method is supplied to the sub control unit 203.

  Further, when the storage capacity of the ROM 203b constituting the sub-control unit 203 has a margin compared with the storage capacity of the ROM 201b constituting the main control unit 201, the main control unit 201 is either the first or second authentication value. Alternatively, the authentication data 303 obtained by performing both of these as they are or by performing a relatively simple or low encryption operation is supplied to the intermediate unit 202, and the intermediate unit 202 obtains the first authentication value obtained from the received authentication data 303. Or the first authentication result obtained by authenticating the main control unit 201 once and the second authentication value are subjected to a complicated or advanced re-encryption operation, or more complicated after decrypting the encryption operation result or Intermediate processing information 304 obtained by performing an intermediate operation such as an advanced re-encryption operation is supplied to the sub-control unit 203.

  This is not only the case where there is a difference in the processing capacity of the CPUs 201a and 203a and the storage capacities of the ROMs 201b and 203b constituting the main control unit 201 and the sub control unit 203, respectively, but there is no such difference. 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 (for example, version upgrade), the data structure of data to be communicated, etc. The same applies to the case where a formal difference occurs between the main control unit and the peripheral unit.
