Description

  The present invention relates to a gaming machine including a plurality of boards and performing communication authentication between these boards and a gaming machine authentication method.

  Conventionally, in gaming machines having a plurality of boards, various techniques have been proposed for preventing fraud on these boards. An example of a gaming machine provided with a plurality of boards is a pachinko gaming machine. The pachinko gaming machine includes a main control board that controls the operation of the entire gaming machine, and a controlled board (peripheral board) that performs the operation of each part of the gaming machine. The main control board outputs a control signal including a control command to the peripheral board, and the other peripheral boards have a function of executing an operation according to the control signal transmitted from the main control board.

  In the case of a gaming machine having such a configuration, the illegality with respect to the main control board includes, for example, replacing a regular main control board with an illegal control board, or altering a program code that defines processing performed by the main control board. There is a technique. In order to prevent such fraud, for example, a technique has been proposed in which program data recorded in a ROM mounted on the main control board is checked by a ROM checker to prevent illegal exchange of the ROM ( For example, see the following Patent Document 1.)

  Further, in Patent Document 2, a control command is transmitted from the main control board to the sub control board, and further, a state monitoring command for monitoring the communication state of the control command in a predetermined communication path is transmitted. A configuration is described in which the validity of a control command is verified using a monitoring command and control of a control target is stopped when it is determined that there is an error.

JP 11-333108 A JP 2002-18095 A

  However, in the case of Patent Document 1 described above, the alteration of the program data can be detected. However, if an unauthorized control board is connected between the regular main control board and the controlled board, There has been a problem that it is not possible to prevent unauthorized control by an unauthorized control signal that is output.

  In addition, as in Patent Document 2 described above, when a state monitoring command different from the control command is transmitted from the main control board to the controlled board, the gaming machine may be cheated ("got" action). Yes, since the state monitoring command is likely to be illegally analyzed by the unauthorized control board or the like interposed between the main control side and the controlled side, if the analysis cannot be made difficult, It was difficult to realize with. Further, if complicated encryption is performed at the time of transmission, there is a problem that processing of each of the regular main control board and the controlled board becomes complicated and processing load increases.

  Furthermore, in order to prevent unauthorized analysis, it may be possible to complicate authentication processing using a plurality of types of authentication commands. However, in conventional gaming machines, a plurality of types of control commands are used. Therefore, in order to add a plurality of new authentication commands (authentication information) to this conventional command system, it is necessary to newly add processing corresponding to each command to the main control side, Since the processing on the main control side becomes complicated, it is difficult to realize in a gaming machine.

  In recent years, in order to improve the interest of games, there is a tendency for various effects to appeal to the visual and auditory senses of players during a reach or jackpot. Therefore, if the CPU on the peripheral part (peripheral board) side tries to execute the authentication process in addition to the existing process, the processing load of the CPU increases and the processing speed decreases, and the display for the production is smooth. In the worst case, the authentication process itself could not be added.

  When various data used for authentication are changed in response to the generation of an authentication command, when attention is paid to the authentication command, for example, the change target, change timing, change method, etc. are illegally analyzed. Therefore, there is a need to make unauthorized analysis even more difficult without complicating normal processing.

  In order to solve the above-described problems caused by the prior art, the present invention suppresses an increase in processing load on the peripheral CPU even if data used for authentication and authentication is changed with one type of authentication information. It is an object of the present invention to provide a gaming machine and a gaming machine authentication method capable of making it difficult to illegally analyze information and changes using the authentication information.

Then, when the data type of the post-stage type information indicates the authentication data, the post-stage part includes authentication data for authentication information received from the main control unit via the peripheral part and three types of first expected values, Each of the second expected value and the third expected value is compared, and subsequent authentication result data indicating the authentication result of the main control unit based on the comparison result can be generated and transmitted to the peripheral unit. Then, when the authentication of the main control unit is established, the latter part identifies the data type associated with the expected value that matches the authentication data of the authentication information as the next data type and updates the latter part type information. can do. Then, when the authentication is established with the third expected value, that is, when the third inspection value is received, the subsequent stage unit changes the expected value received from the main control unit among the correction value and the coefficient value. The value used for the data is switched by the same switching method as the main control unit. Then, when the subsequent unit switches from the coefficient value to the correction value, the initial value of the predetermined expected value among the first to third expected values is based on the expected value changing data received from the main control unit. Can be changed. Further, when switching from the correction value to the coefficient value, the subsequent stage unit can change the expected value that is predetermined and changed last among the first to third expected values based on the expected value changing data. On the other hand, the peripheral unit can perform a predetermined process in the gaming machine corresponding to each of a plurality of types of control commands received from the main control unit, according to the subsequent authentication result data received from the subsequent unit.

A correction value changing step that is changed based on the expected value changing data, and the test value that was changed last time is changed based on the expected value changing data in response to switching to the coefficient value in the expected value changing data switching step. An expectation value storing step in which the expectation value having the first expectation value, the second expectation value, and the third expectation value is stored in advance in expectation value storage means. A data type of the authentication information received this time by the latter-stage-side receiving process for receiving the authentication information transferred from the peripheral portion and the latter-stage-side type information stored in the latter-stage-side type information storage means In the case of indicating that it is data, the authentication data of the received authentication information and the first expected value, the second expected value, and the third expected value stored in the expected value storage means Compare and based on the comparison result A post-stage authentication result data generating step for generating post-stage authentication result data indicating an authentication result of the main control unit, a post-stage side transmission step for transmitting the generated post-stage authentication result data to the peripheral unit, and for authentication of the authentication information The value used for the expected value change data received from the main control unit, out of the correction value and the coefficient value, when the data is authenticated based on the third expected value.

  According to the gaming machine authentication method of the present invention described in claim 8 above, the main control unit, for example, according to the activation of the gaming machine, detection of a predetermined timing, etc., the first inspection value, the second inspection value Then, at least one of the inspection values having the third inspection value is generated based on predetermined storage data of the main control unit, and is stored as an inspection value in the inspection value storage means. Two types of data with different authentication information are associated with the first inspection value and the second inspection value, respectively, and switching between a correction value and a coefficient value is associated with the third inspection value. Then, when the type information indicates the authentication data, the main control unit selects one inspection value from the first inspection value, the second inspection value, and the third inspection value stored in the inspection value storage means. Is selected at random, authentication data having one selected inspection value is generated. The main control unit determines the data type associated with the selected first inspection value, second inspection value, and third inspection value in advance as the next data type. When the third inspection value is selected, the main control unit switches the value used for generating the expected value changing data among the correction value and the coefficient value that are selectively used for the expected value changing data by the switching method. When the type information indicates expected value change data, the main control unit generates expected value change data for changing each of the inspection value and the expected value with the switched correction value or coefficient value. The main control unit can generate authentication information having the generated authentication data or expected value change data, and transmit the generated authentication information to the subsequent unit via the peripheral unit. Then, the main control unit updates the type information stored in the type information storage means so as to indicate the determined next data type. Then, after generating the expected value changing data of the correction value, the main control unit changes the initial value of the predetermined inspection value among the first to third inspection values based on the expected value changing data. be able to. In addition, after generating the expected value change data of the coefficient value, the main control unit changes the predetermined and previously changed test value among the first to third test values based on the expected value change data. be able to. On the other hand, the peripheral part transfers the authentication information received from the main control part and each of a plurality of types of control commands to the subsequent part. On the other hand, the latter stage unit outputs three types of first expected value, second expected value, and third expected value corresponding to each of the three types of first test value, second test value, and third test value of the main control unit. The expected value is stored in advance in the expected value storage means at the time of manufacture or the like. Then, when the data type of the post-stage type information indicates the authentication data, the post-stage part includes authentication data for authentication information received from the main control unit via the peripheral part and three types of first expected values, Each of the second expected value and the third expected value is compared, and subsequent authentication result data indicating the authentication result of the main control unit based on the comparison result can be generated and transmitted to the peripheral unit. Then, when the authentication of the main control unit is established, the latter part identifies the data type associated with the expected value that matches the authentication data of the authentication information as the next data type and updates the latter part type information. can do. Then, when the authentication is established with the third expected value, that is, when the third inspection value is received, the subsequent stage unit changes the expected value received from the main control unit among the correction value and the coefficient value. The value used for the data is switched by the same switching method as the main control unit. Then, when the subsequent unit switches from the coefficient value to the correction value, the initial value of the predetermined expected value among the first to third expected values is based on the expected value changing data received from the main control unit. Can be changed. Further, when switching from the correction value to the coefficient value, the subsequent stage unit can change the expected value that is predetermined and changed last among the first to third expected values based on the expected value changing data. On the other hand, the peripheral unit can perform a predetermined process in the gaming machine corresponding to each of a plurality of types of control commands received from the main control unit, according to the subsequent authentication result data received from the subsequent unit.

  As described above, according to the present invention, since the main control unit generates a predetermined test value among the first to third test values, the test value to be generated is transmitted to the main control unit. Since it is not necessary to store in advance, an increase in the amount of data stored in advance for authentication of the main control unit in the gaming machine can be suppressed. Even if the data of the main control unit is illegally analyzed, the generated test value is not stored, which can contribute to prevention of illegal analysis for authentication of the main control unit. Then, the control unit associates two types of authentication information with each of the first inspection value and the second inspection value among the three types of inspection values, and authenticates with the first inspection value or the second inspection value. Since the authentication data having the authentication data is generated and transmitted to the latter part, the latter part associates the data type with the expected value so that the authentication information has When the inspection value matches the expected value, the authentication of the main control unit can be established and the data type of the authentication information to be received next time can be specified. It can be prevented from being used. Further, the main control unit switches between the correction value and the coefficient value that are selectively used for the expected value change data according to the generation or transmission of the authentication information having the third inspection value, and the subsequent stage unit switches the correction value and the coefficient value. Since switching is performed in response to reception of authentication information having the third inspection value, it is possible to change the switching method and switching timing of the inspection value and the expected value, so that analysis by an unauthorized analyst can be performed. It can be made even more difficult. And since the latter part can synchronize with the switching of the main control part if the correction value and the coefficient value are switched in response to reception of the authentication information having the third inspection value, the main control part and the latter part Thus, the inspection value and the expected value can be changed in a uniform manner, and analysis by an unauthorized analyst can be made even more difficult. Since only one type of authentication information has to be used, it is possible to minimize the addition to the conventional command system and prevent the processing of the main control unit from becoming complicated. Furthermore, since the latter part can detect that the authentication information has been used illegally by the fraud analyst by the data type of the authentication information, the authentication strength of the authentication information can be increased. In addition, since the latter part performs authentication processing for the main control unit and transmits the subsequent authentication result to the peripheral part, the peripheral part only needs to refer to the latter authentication result without performing the authentication process. The processing load on the peripheral CPU can be reduced. Furthermore, since three types of inspection values can be stored in advance, it is not necessary to perform complicated calculations when generating authentication information, and an increase in processing load on the main control unit can be prevented. In addition, since the peripheral unit transmits the authentication information from the main control unit to the subsequent unit as it is, the peripheral unit can perform the predetermined process and the subsequent unit can perform the authentication process. It is possible to prevent a delay in the processing. Therefore, even if data used for authentication and authentication is changed with one type of authentication information, there is an effect that it is possible to make unauthorized analysis of the authentication information and the change difficult.

  In the gaming machine described above, the main control unit generates at least one of the first to third inspection values based on the stored data in response to the activation of the gaming machine. It is not necessary to store the inspection value to be generated in advance, and since the main control unit can be authenticated immediately after the game machine is started, it is possible to contribute to the improvement of the authentication strength of the authentication information.

  In the gaming machine described above, the main control unit and the subsequent stage unit store the inspection value and the expected value changed with the expected value change data of the coefficient value as the previous inspection value for the coefficient value and the previous expected value for the coefficient value, When the correction value is switched to the coefficient value again, the last changed inspection value and expected value are continuously changed, so that the changed inspection value and expected value can be made irregular. Therefore, analysis by an unauthorized analyst can be made even more difficult.

  In the gaming machine described above, the main control unit and the subsequent stage unit associate the switching timing of the correction value and the coefficient value with the detection of the detection target control command determined in advance from a plurality of types of control commands. Since the switching timing intervals can be made irregular and the correction value and coefficient value can be switched between the main control unit and the subsequent stage unit, illegal analysis can be made more difficult. it can.

  In the above gaming machines, for example, jackpot related commands in gaming machines such as jackpot reach command, jackpot start command, jackpot command, jackpot end command, etc., are used as detection target control commands. Therefore, if an illegal jackpot related command is transmitted to the peripheral part, the latter part detects it as a detection target control command and switches between the correction value and the coefficient value. It is possible to make the correction value and the coefficient value inconsistent. Therefore, it is possible to contribute to improving the accuracy of detecting the occurrence of fraud.

(Functional configuration of main control board and peripheral board)
First, a functional configuration of the main control board 310 having a function as the main control unit 201 will be described with reference to FIG.

As the data storage unit 311, for example, a part of the ROM 212 and the RAM 213 (see FIG. 2) of the main control unit 201 can be used. In addition, the data storage unit 311 has a storage area for storing authentication information transmitted to the peripheral unit 202A. The authentication information stored in the data storage unit 311 can have various different embodiments such as a configuration for storing only one transmission, and a configuration for storing a plurality of transmissions in time series.

  The authentication data is data used by the rear stage 202B of the peripheral board 330 for authentication of the main control board 310 (main control section), and is generated by the CPU 211 described above.

Specifically, type data for indicating the data type is associated with each of the first test value and the second test value. The third inspection value is defined as switching between a correction value and a coefficient value, which will be described later. The correction value means a value (change method) for changing a predetermined initial inspection value and expected value. The coefficient value means a value (change method) for accumulating and changing the inspection value and the expected value that were changed last time.

  The third inspection value of the present embodiment is stored in the data storage unit 311 in association with switching information for switching between the correction value and the coefficient value. The switching information is information indicating the switching order of correction values and coefficient values, switching timing, and the like. Examples of the switching information include a configuration indicating which one of the correction value and the coefficient value is first, a configuration indicating a switching pattern of the correction value and the coefficient value, and a switching order thereof.

  The switching information of the present embodiment will be described later in order to link the timing of switching between the correction value and the coefficient value to the detection of a detection target control command determined in advance from a plurality of types of control commands in the pachinko gaming machine 100. The control command detection unit 325 is stored in the data storage unit 311 in association with detection target control command information indicating a detection target control command to be detected. As for the detection target control command, the switching timing of the correction value and the coefficient value can be further complicated by switching a plurality of types of control commands. The third inspection value may be stored in the data storage unit 311 in association with the above-described data type. Further, the switching information may be an embodiment incorporated as a part of a program for realizing the present invention.

  In the present embodiment, a case where three types of first to third inspection values and corresponding first to third expected values are used will be described. Instead, a plurality of third inspection values and third expected values are used. By using types, it is possible to obtain three or more types of inspection values and expected values. In that case, an embodiment that uses only a predetermined one of the two types of third inspection value and the third expected value, or different switching information for each of the two types of third inspection value and the third expected value. This can be dealt with by an embodiment that uses the switching information for both of them.

  The type information has a data structure indicating the data type of the authentication information generated by the main control unit 201 this time. For example, the type information includes current type data and next type data, and each type of data is data for identifying authentication data and expected value change data. It should be noted that the type information can have a data structure of only the current type data by setting the next type data at the end of the authentication process.

  The inspection value generation unit 312 corresponds to inspection value generation means of the present invention, and at least one of a first inspection value, a second inspection value, and a third inspection value that is selectively used for the authentication data, It is generated based on predetermined storage data of the main control unit 310 and a predetermined generation method. The stored data is unique data of the main control unit 310 stored in advance in the ROM 212 of the main control unit 201. Examples of stored data include program data executed by the CPU 211 of the main control unit 310, fixed data dedicated for authentication, etc., in which case the data is determined by the time of manufacturing the pachinko gaming machine 100, etc. Will do. And, since the main control board 310 may control the jackpot related program data (a part of the program data stored in the ROM 212) for controlling the jackpot in the pachinko gaming machine 100, the jackpot related program data may be illegally rewritten. By using stored data having program data, the inspection value generated by the inspection value generation unit 312 does not match the expected value, so that the occurrence of unauthorized rewriting can be detected.

  The inspection value generation unit 312 generates inspection values at a predetermined generation timing. Examples of the generation timing include when the pachinko gaming machine 100 is activated, when a predetermined control command is generated or when a predetermined number of times are generated, a predetermined time, every time the main control board 310 is authenticated, and the like. . Each time the main control board 310 is authenticated means a timing for generating authentication information to be described later.

  As an example of a generation method of the inspection value generation unit 312, a checksum of stored data in different predetermined areas (ranges) in the ROM 212, a total value of odd addresses or even addresses of the predetermined areas, predetermined for the ROM 212. Stored values extracted from a plurality of different addresses. In addition, about the production | generation timing and production | generation method of the test value production | generation part 312, it can be set as a different setting for every kind of pachinko game machine 100, every specification, etc., for example.

  The inspection value generation unit 312 of the present embodiment will be described in the case of generating all of the first to third inspection values different from each other, but instead of this, at least one inspection value among the first to third inspection values is used. It can also be an embodiment to generate. However, since the inspection value stored in advance in the ROM 212 of the main control unit 201 can be reduced as the number of inspection values generated by the inspection value generating unit 312 is increased, the main control board 310 of the pachinko gaming machine 100 can be reduced. An increase in the amount of data stored in the ROM 212 related to authentication can be suppressed. In addition, since the inspection value generation unit 312 generates all of the first to third inspection values, even if the main control unit 201 is illegally analyzed, the first to third inspection values do not exist. It can contribute to prevention of fraud analysis.

  Further, in the present embodiment, a case will be described in which each of the inspection value generation unit and the inspection value storage unit of the present invention is realized separately by the inspection value generation unit 312 and the data storage unit 311. The inspection value generation means and the inspection value storage means can be realized integrally. For example, two means can be realized with one piece of hardware by causing the CPU 211 to function as an inspection value generation unit and causing the register of the CPU 211 to function as an inspection value storage unit. Alternatively, dedicated hardware having a circuit for realizing the test value generation means and the test value storage means may be used.

  The switching determination unit 313 corresponds to the switching determination unit of the present invention, and randomly determines whether to switch the different data types. In other words, the switching determination unit 313 is a unit that determines which data type to switch between the authentication data and the expected value change data, or to switch the detection target control command. The switching determination unit 313 makes it difficult for a fraud analyst to analyze illegally by making irregular determinations using, for example, random numbers, tables, and the like. Note that the switching determination unit 313 is premised on the operation after the inspection value generation unit 312 generates the inspection value. However, when the operation is performed before the generation, the switching determination unit 313 performs processing based on the determination result of the generation. It can respond by limiting.

  The determining unit 314 corresponds to a determining unit of the present invention. When the switching determining unit 313 determines to switch the data type, the data type of the authentication information that the main control board 310 generates next time is the authentication data and the expected value. Randomly determined from the two types of data for change. Then, the determination unit 314 determines the next data type irregularly using, for example, a random number, a table, or the like so that the authentication data and the expected value change data are in an irregular order. It makes it difficult for an analyst to analyze it illegally.

  The first extraction unit 315 corresponds to a first extraction unit of the present invention, and stores a first inspection value or a second inspection value associated with the next data type determined by the determination unit 314 as a data storage unit (inspection value storage). Means) Extract from 311 and store the extracted inspection value in the RAM 213 or the like. Then, one inspection value extracted by the first extraction unit 315 becomes an inspection value used as authentication data for the authentication information generated this time.

  The second extraction unit 316 corresponds to the second extraction unit of the present invention. When the switching determination unit 313 determines that the data type is not switched, that is, the correction value and the coefficient value are switched, the third inspection value is obtained. The data is extracted from the data storage unit (inspection value storage means) 311 and the extracted third inspection value is stored in the RAM 213 or the like. Then, the third inspection value extracted by the second extraction unit 316 becomes the inspection value used as authentication data for the authentication information generated this time.

  The authentication data generation unit 317 corresponds to the authentication data generation unit of the present invention. When the type information stored in the data storage unit 311 indicates authentication data, the authentication data generation unit 317 Authentication data having the inspection value extracted by the extraction unit 316 is generated, and the authentication data is stored in the data storage unit 311 or the like. The authentication data generation unit 317 generates authentication data for the extracted inspection value using a data type that is a predetermined initial value in the first process, and in the second and subsequent processes, Since the next data type is determined by the determination unit 314 in this process, authentication data for the extracted inspection value is generated using the next data type. The authentication data generated in this way is one value of three types of test values extracted at random. In the present embodiment, the case where the authentication data is the extracted inspection value will be described. Instead of this, for example, the calculation method determined in advance between the main control unit 201 and the subsequent unit 202B is used. A value obtained by calculating the extracted inspection value may be used as authentication data.

  The expected value changing data switching unit 318 corresponds to the expected value changing data switching means of the present invention, and among the correction values and coefficient values that are selectively used for the expected value changing data, The value used for generation is switched by a switching method determined in advance in accordance with the switching determination unit 313 determining that the data type is not switched. The expected value changing data switching unit 318 can switch between the correction value and the coefficient value in accordance with selection of the third inspection value, generation or transmission of authentication information having the third inspection value, and the like. Then, the expected value changing data switching unit 318 of the present embodiment describes a case where the correction value and the coefficient value are alternately switched based on the above-described switching information. You may make it switch based on a switching pattern.

  For example, when the switching information indicates the switching order between the correction value and the coefficient value and the currently set value, and the correction value is set in the switching information, the expected value changing data switching unit 318 switches to the coefficient value. To update the switching information. When a coefficient value is set in the switching information, the expected value changing data switching unit 318 switches to the correction value and updates the switching information.

  The expected value change data generation unit 319 corresponds to the expected value change data generation means of the present invention. When the type information stored in the data storage unit 311 indicates the expected value change data, the determination unit In response to the determination of the expected value change data by 314, generation of expected value change data for changing each of the three types of inspection values of the main control board 310 and the three types of expected values of the rear stage section 202B in the peripheral board 330 is generated. Then, the expected value changing data is stored in the data storage unit 311 or the like. The expected value change data generation unit 319 generates expected value change data so as to have different values, irregular values, and the like at an arbitrary generation timing. The expected value changing data is either the correction value or the coefficient value described above.

  The authentication information generation unit 320 corresponds to the authentication information generation unit of the present invention, and includes authentication data generated by the authentication data generation unit 317 or expected value change data generated by the expected value change data generation unit 319. Generate information. The authentication information generation unit 320 of the present embodiment generates authentication information having either one of authentication data or expected value change data, and authentication commands different from a plurality of types of control commands in the pachinko gaming machine 100. The case of generating will be described. Alternatively, the authentication information may have a data structure further including other data.

  The main control side transmitting unit 321 corresponds to the main control side transmitting unit of the present invention, and each of the authentication information generated by the authentication information generating unit 320 and the plurality of types of control command data for controlling the peripheral unit 202A is set at different timings. Then, the data is individually transmitted to the rear stage section 202B via the peripheral section 202A of the peripheral board 330. Then, the main control side transmission unit 321 of the present embodiment transmits the control command data as a control signal to the peripheral part 202A of the peripheral board 330, and the peripheral part 202A transfers (transmits) the signal to the subsequent stage part 202B. . Further, the main control side transmission unit 321 transmits the authentication information as an authentication information signal which is a signal different from the control signal to the peripheral unit 202A, and the peripheral unit 202A transfers (transmits) the signal to the subsequent unit 202B. ) Thereby, in pachinko gaming machine 100, the control signal and the authentication information signal are differentiated.

  The update unit 322 corresponds to the update unit of the present invention, and updates the type information stored in the data storage unit 311 so as to indicate the next data type determined by the determination unit 312. The next data type indicated by the type information is used as the current data type in the next authentication process in the main control board 310.

  The correction value changing unit 323 corresponds to the correction value changing unit of the present invention, and the data storage unit 311 (inspection value storage unit) according to the switching of the coefficient value from the coefficient value of the expected value change data switching unit 318 to the correction value. ) Stored in the expected value change data generation unit 319 generates at least one predetermined initial value among the three types of first test value, second test value, and third test value. Change based on change data. The correction value changing unit 323 changes the three types of inspection values using a change method and expected value changing data that are predetermined between the main control board 310 and the rear stage part 202B of the peripheral board 330. . As the change method, for example, various calculation methods such as +, −, *, /, AND, OR, XOR, and a predetermined function can be used. Then, the correction value changing unit 323 stores the changed inspection value obtained by changing the initial inspection value stored in advance in the ROM 212 or the like with the expected value changing data in the data storage unit 311 or the like, and stores the first extraction value. The unit 315 and the second extraction unit 316 extract change inspection values that change according to the change. Then, the change timing of the correction value changing unit 323 can be set, for example, when the expected value changing data is generated, when the detection target control command described above is detected, or the like.

  The coefficient value changing unit 324 corresponds to the coefficient value changing unit of the present invention, and the data storage unit 311 (inspection value storage unit) according to switching from the correction value to the coefficient value of the expected value changing data switching unit 318. ) Stored in the expected value changing data generation unit 319 generates at least one of the three types of first inspection value, second inspection value, and third inspection value. Change based on data. The coefficient value changing unit 324 changes the value changed using the predetermined change method and the expected value changing data between the main control board 310 and the rear stage part 202 </ b> B of the peripheral board 330 in the previous inspection for coefficient value. The value is stored in the data storage unit 311 (coefficient value previous inspection value storage means). The initial inspection value generated by the inspection value generation unit 312 in the initial processing of the pachinko gaming machine 100 or the like is set as the previous inspection value for coefficient value. The coefficient value changing unit 324 changes the previous inspection value for coefficient value stored in the data storage unit 311 with the expected value changing data. The change timing of the coefficient value changing unit 324 can be set, for example, at the time of generating expected value changing data, at the time of detecting the detection target control command described above, and the like, similarly to the correction value changing unit 323.

  When the coefficient value changing unit 324 is switched from the correction value to the coefficient value by the expected value changing data switching unit 318, that is, when the coefficient value is switched from the coefficient value to the correction value, the coefficient value changing unit 324 is switched to the coefficient value again. By diverting the previous inspection value for coefficient value stored in the data storage unit 311 (previous inspection value storage means for coefficient value), and changing the previous inspection value for coefficient value based on the expected value changing data, Since the change result by the previous coefficient value can be taken over, unauthorized use of authentication information can be made even more difficult. The coefficient value changing unit 324 may initialize the coefficient value previous inspection value with the initial inspection value or the like every time the correction value is switched to the coefficient value.

  The control command detection unit 325 corresponds to the control command detection means of the present invention, and is determined in advance from a plurality of types of control commands in the pachinko gaming machine 100 in accordance with generation or transmission of authentication information having the third inspection value. The generation or transmission of a detection target control command is detected. The detection target control command may be one type of control command among a plurality of types of control commands, or two or more types of control commands. Then, the above-described expected value changing data switching unit 318 switches the correction value and the coefficient value by the switching method in accordance with the detection of the control command detection unit 325. That is, in the present embodiment, the timing detected by the control command detection unit 325 is the switching timing of the expected value change data switching unit 318.

  When the pachinko gaming machine 100 of the present invention uses three types of inspection values for authentication of the main control board 310, the main control board 310 can change these inspection values with the expected value change data, so that the peripheral board The subsequent stage unit 202A of 330 acquires the expected value change data from the main control board 310, and changes the expected value corresponding to the inspection value with the expected value change data, so that the changed inspection value and expected value are obtained. Based on this, a configuration for authenticating the main control board 310 is adopted. Since the three types of inspection values are generated by the main control board 310 after the pachinko gaming machine 100 is started, it is not necessary to store in advance the inspection values used by the main control board 310 for authentication. Analysis can be made difficult. Further, since the inspection value is changed by generating the expected value changing data by switching the correction value and the coefficient value, it is possible to make unauthorized analysis difficult. Therefore, even if the pachinko gaming machine 100 authenticates with one type of authentication information, it can make it difficult to illegally analyze the authentication data, so that security can be improved.

  Next, a functional configuration of the peripheral board 330 having a function as a peripheral part such as the above-described effect control unit 202A will be described. As shown in FIG. 3, the peripheral board 330 includes a peripheral part (effect control part) 202 </ b> A and a rear stage part 202 </ b> B. And the peripheral board | substrate 330 is comprised so that bidirectional | two-way communication is possible between the peripheral part (effect control part) 202A and the back | latter stage part 202B. In this embodiment, the peripheral board 330 having the production control unit 202A and the rear stage part 202B will be described, but instead, a peripheral board provided with the rear stage part 202B on the prize ball control unit 203 side. You can also Further, the effect control unit 202A and the rear stage unit 202B may be separate boards, and for example, the board of the rear stage unit 202B may be mounted on the board of the effect control unit 202A.

  First, the post-stage unit 202B includes a post-stage side reception unit 331, a post-stage side storage unit 332, a post-stage authentication result data generation unit 333, a post-stage side transmission unit 334, a post-stage side expected value change data switching unit 335, and a post-stage side correction value change. 336, a rear side coefficient value changing unit 337, a specifying unit 338, and a rear side control command detecting unit 339.

  The post-stage receiving unit 331 corresponds to the post-stage receiving unit of the present invention. The main control board 310 transmits a plurality of types of control command data, authentication information, and the like transmitted from the peripheral unit 202A to the peripheral unit 202A. Receive. The rear receiving unit 331 of the present embodiment receives, for example, a control signal corresponding to the control command data and an authentication information signal corresponding to the authentication information, thereby receiving a plurality of types of control command data and authentication information on the main control board 310. From the peripheral portion 202A. Then, the subsequent-stage receiving unit 331 stores the control command history indicated by the received control signal in the subsequent-stage storage unit 332.

  The latter stage storage unit 332 corresponds to the expected value storage unit and the latter stage type information storage unit of the present invention. The post-stage storage unit 332 is a first test value generated by the test value generation unit 312 of the main control board 310 and stored in the data storage unit 311. Three types of expected values that coincide with each of the inspection value, the second inspection value, and the third inspection value are stored. The three types of expected values include a first expected value corresponding to the first test value, a second expected value corresponding to the second test value, and a third expected value corresponding to the third test value. Have. As a result, the post-stage unit 202B can determine that the authentication data is a regular inspection value if the inspection value of the authentication data set in the authentication information matches the expected value. If the inspection value and the expected value of the authentication data do not match, it can be determined that the authentication data is not the inspection value. The first to third expected values described above are stored in advance when the pachinko gaming machine 100 is manufactured.

  In the present embodiment, description will be made on the premise that the inspection value and the expected value are stored in advance, but the present invention can change the expected value by the above-described expected value changing data. Therefore, the expected value stored in advance may be a value different from the inspection value of the main control board 310, that is, a value that does not match. Note that the third expected value may be stored in the subsequent-stage storage unit 332 in association with the data types described above, similarly to the main control board 310.

  Each of the first expectation value and the second expectation value is stored in the subsequent-stage storage unit 332 in a one-to-one correspondence with the data type associated with the corresponding (matching) first check value and second check value. ing. As a result, the post-stage unit 202B can specify the data type of the next authentication information determined by the main control unit 201 from the expected value that matches the inspection value received from the main control unit 201 via the peripheral unit 202A. .

  The third expected value is stored in the subsequent-stage storage unit 332 in association with the same information as the switching information associated with the corresponding (matched) third inspection value. The latter-stage storage unit 332 of this embodiment stores switching information and the detection target control command information associated with the switching information. As a result, the post-stage unit 202B can switch between the correction value and the coefficient value based on the switching information when the third inspection value received from the main control unit 201 matches the third expected value.

  The first to third expected values are values that match at least one of the inspection value generated by the inspection value generation unit 312 of the main control board 310 and the predetermined inspection value. For example, the design of the pachinko gaming machine 100 It is calculated based on the storage data of the main control board 310 and the generation method at the time of manufacture, at the time of manufacture, etc., and is stored in advance in the ROM 22 of the rear-stage storage unit 332 at the time of manufacture of the pachinko gaming machine 100 or the like.

  The latter-stage storage unit 332 stores latter-stage type information indicating the data type of the current authentication information. The post-stage type information has the same data structure as the type information of the main control board 310 described above, and matches the data type indicated by the type information of the main control board 310 when no fraud has occurred. Therefore, before receiving the authentication information from the main control board 310, the latter stage unit 202B can grasp the data type of the received authentication information in advance by referring to the latter stage type information. Further, the rear-stage storage unit 332 stores various data such as the same switching information, detection target control command information, and coefficient value previous expected value as the main control board 310 described above.

  The post-authentication result data generation unit 333 corresponds to post-authentication result data generation means of the present invention. When the data type of the post-stage side type information indicates the authentication data, the inspection value that is the authentication data Is compared with the expected value stored in the rear-stage storage unit 332, and subsequent-stage authentication result data indicating the authentication result of the main control board 310 based on the comparison result is generated. That is, the latter-stage authentication result data indicates an authentication result indicating whether or not the latter-stage unit 202B has authenticated the main control board 310 (main control unit 201). Then, as an example of the authentication method of the latter-stage authentication result data generation unit 333, it is determined whether any one of the inspection value and the first to third expected values matches, and matches among the first to third expected values. If there is an expected value to be satisfied, authentication of the main control board 310 is established, and if there is no matching expected value, authentication is not established.

  The post-stage transmission unit 334 corresponds to the post-stage transmission unit of the present invention, and transmits the post-stage authentication result data generated by the post-stage authentication result data generation unit 333 to the peripheral unit 202A. Then, the post-stage transmission unit 334 transmits the generated post-stage authentication result data to the peripheral unit 202A as a post-stage authentication result signal, for example.

  The latter-stage expected value changing data switching section 335 corresponds to the latter-stage expected value changing data switching means of the present invention, and the authentication data of the authentication information is authenticated by the main control section based on the third expected value. Is established, the value used for the expected value change data received from the main control unit 201 is switched between the correction value and the coefficient value by the same switching method as the main control unit 201. In response to the reception of the third inspection value from the main control unit 201, the subsequent-stage expected value change data switching unit 335 alternates the correction value and the coefficient value based on the switching information in the same manner as the main control unit 201 or the Switching can be performed with a predetermined switching pattern.

  The post-stage correction value changing unit 336 corresponds to the post-stage correction value changing unit of the present invention, and the post-stage type information indicates the expected value change data and the post-stage side expected value change data switching unit 335 is involved. When the numerical value is changed to the correction value, the expected value changed last time is changed based on the expected value changing data included in the received authentication information and the changing method. Similarly to the correction value changing unit 323, the post-stage correction value changing unit 336 has at least one predetermined initial value among the three types of first expected value, second expected value, and third expected value. Is changed based on the expected value changing data. The rear-stage correction value changing unit 336 stores the changed expected value obtained by changing the initial expected value stored in advance in the ROM 242 or the like with the expected value changing data in the rear-stage storage unit 332 or the like. The change timing of the post-stage correction value changing unit 336 can be, for example, when receiving expected value changing data, when detecting the detection target control command described above, or the like.

  The post-stage coefficient value changing unit 337 corresponds to the post-stage coefficient value changing means of the present invention. The post-stage side type information indicates the expected value change data and the post-stage side expected value change data switching section 335 is corrected. In accordance with the switching from the value to the coefficient value, a predetermined one of the three types of first expected value, second expected value, and third expected value stored in the rear-stage storage unit 332 (expected value storage means) is determined in advance. Then, at least one is changed based on the received expected value changing data and the changing method. The rear-stage coefficient value changing unit 337 uses a value changed between the main control board 310 and the rear-stage unit 202B using the predetermined change method and the expected value changing data as the previous expected value for the coefficient value. The data is stored in the subsequent-stage storage unit 332 (previous value storage unit for coefficient values). If the previous expected value for coefficient value is stored in the subsequent-stage storage unit 332, the subsequent-stage coefficient value changing unit 337 changes the value with the expected-value changing data, and the previous expected value for coefficient value is If not stored, the initial expected value is changed with the expected value changing data. The change timing of the post-stage side coefficient value changing unit 337 is, for example, when receiving the expected value change data, when detecting the above-described detection target control command, and the like, similar to the post-stage side correction value changing unit 336. Can do.

  If the subsequent-stage correction value changing unit 336 and the subsequent-stage coefficient value changing unit 337 receive incorrect authentication information when the data type of the subsequent-stage type information indicates the expected value changing data, Since the expected value is changed with simple data, the value is changed to a value different from the inspection value of the main control board 310, and authentication of subsequent authentication information is not established.

  The specifying unit 338 corresponds to the specifying unit of the present invention. When the authentication of the main control board 310 is established by the post-authentication result data generation unit 333, the specifying unit 338 associates with the expected value that matches the inspection value constituting the authentication data. The specified data type is specified as the next data type, and the subsequent-stage type information stored in the subsequent-stage storage unit 332 is updated so as to be the specified next data type.

  The post-stage control command detection unit 339 corresponds to the post-stage control command detection means of the present invention, and a plurality of types of pachinko gaming machines 100 in response to reception of authentication information having a third inspection value from the main control unit 201. The reception from the main control board 310 of the detection target control command that is set in the detection target control command information that is predetermined from the control command and that is the same as that of the main control board 310 is detected. In addition, as the main control board 310, the detection target control command may be one type of control command among a plurality of types of control commands, or two or more types of control commands. The latter-stage expected value change data switching unit 335 switches between the correction value and the coefficient value by the switching method in accordance with the detection by the latter-stage control command detection unit 339. In other words, in the present embodiment, the timing detected by the subsequent-stage control command detection unit 339 is the switching timing of the subsequent-stage expected value change data switching unit 335.

  Next, the peripheral unit 202A includes a transfer unit 351, a peripheral side reception unit 352, and a processing unit 353.

  The transfer unit 351 corresponds to a transfer unit of the present invention, receives authentication information and a plurality of types of control command data from the main control board 310, and sends the received authentication information and a plurality of types of control command data to the subsequent stage unit 202B. Forward. For example, when receiving the authentication information signal and the control signal corresponding to the authentication information from the main control board 310, the transfer unit 351 of the present embodiment transmits the authentication information signal and the control signal to the subsequent unit 202B as they are. The authentication information and a plurality of types of control command data are transferred to the rear stage unit 202B.

(Basic operation of pachinko machines)
An example of the basic operation of the pachinko gaming machine 100 configured as described above will be described. The main control unit 201 outputs the winning status of the game ball for each winning port to the winning ball control unit 203 as a control command. The winning ball control unit 203 pays out the number of winning balls corresponding to the winning situation in accordance with the control command output from the main control unit 201.

  The main control unit 201 outputs a corresponding control command to the effect control unit 202A every time a game ball wins the start winning opening 105, and the effect control unit 202A displays the symbols on the symbol display unit 104 in a variable manner. Repeat to stop. The main control unit 201 outputs a corresponding control command to the effect control unit 202A when the occurrence of the jackpot is determined, and the effect control unit 202A aligns with a predetermined symbol and stops the variable display, Control is performed to open the special winning opening 109. The effect control unit 202A displays various effects in addition to the symbol variation display on the symbol display unit 104 during the jackpot occurrence period and during the reach until the jackpot occurrence or at the time of the reach notice. . In addition, effects such as specific driving for various types of accessories and correction of the display state of the lamp 261 are performed.

  Then, the main control unit 201 opens the big prize opening 109 a plurality of times during the jackpot occurrence period. For example, 15 rounds are repeatedly executed as one open is one round. The period of one round is a period until 10 game balls are won in the big winning opening 109, for example, or a predetermined period (for example, 30 seconds). At this time, the winning ball control unit 203 pays out with, for example, 15 winning balls per winning game ball to the big winning opening 109. The pachinko gaming machine 100 releases the jackpot state after the jackpot ends and returns to the normal gaming state.

(Details of processing by each control unit)
Next, details of various processes performed by each control unit will be described. First, the control process of the effect control unit 202A by the main control unit 201 will be described. 4 to 9, the authentication data and the accompanying data are not considered in order to clarify the control processing procedure of the effect control unit 202A. That is, in the description of FIGS. 4 to 9, “send a command” means “send a control signal including data (control command data) indicating the command”. The presence or absence of data is not considered.

  The main control unit 201 determines in step S401 shown in FIG. 4 whether or not the pachinko gaming machine 100 is powered on. When the main control unit 201 determines that the power is not turned on (S401: No), the main control unit 201 waits until the pachinko gaming machine 100 is turned on by repeating this determination process. On the other hand, when the main control unit 201 determines that the power is turned on (S401: Yes), the main control unit 201 proceeds to the process of step S402.

  In step S402, the main control unit 201 transmits a power-on command to each peripheral unit such as the effect control unit 202A and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this process, the effect control unit 202A controls the lamp control unit 251, the sound control unit 252, and the symbol display unit 104 for effect control at the time of power-on (specifically, Transmits a control command instructing lighting of a lamp, sound output, display of a demonstration (demo) screen, and the like.

  In step S <b> 403, the main control unit 201 refers to the unlottery winning number data stored in the ROM 212 or the RAM 213, and determines whether or not the unlotted winning number is zero. The number of undrawn winnings is the number obtained by subtracting the number of times that a lottery corresponding to the winning ball has been performed (number of already drawn lots) from the number of winning balls detected at the start winning opening 105 (number of winnings). If the main control unit 201 determines that the number of undrawn winning prizes is not zero (S403: No), the process proceeds to step 410. On the other hand, if the main control unit 201 determines that the number of undrawn winning prizes is zero (S403: Yes), in step S404, the main control unit 201 measures the time elapsed since the demonstration was started, and proceeds to the process of step S405. To do.

  The main control unit 201 determines whether or not a predetermined time has elapsed since the demonstration was started. If the main control unit 201 determines that the predetermined time has not elapsed since the demonstration was started (S405: No), the main control unit 201 proceeds to the process of step S407. On the other hand, if the main control unit 201 determines that a predetermined time has elapsed since the demonstration was started (S405: Yes), in step S406, the main control unit 201 transmits a customer waiting demonstration command to the effect control unit 202A, and the process of step S407 Migrate to

  In step S407, the main control unit 201 determines whether or not a winning ball has been detected by the start winning port detection unit 221. If the main control unit 201 determines that no winning ball has been detected (S407: No), the main control unit 201 returns to the process of step S404 and repeats a series of processes. On the other hand, when determining that a winning ball has been detected (S407: Yes), the main control unit 201 clears the time measured since the demonstration was started in step S408, and in step S409, the number of undrawn winning prizes 1 is added to and the process proceeds to step S410. In step S410, the main control unit 201 obtains a jackpot determination random number. In step S411, the main control unit 201 subtracts 1 from the number of undrawn winning prizes, and proceeds to the process of step S412 shown in FIG.

  In step S412, the main control unit 201 determines whether or not the jackpot determination random number is a jackpot random number. If the main control unit 201 determines that it is a jackpot random number (S412: Yes), in step S413, the main control unit 201 transmits a jackpot reach command (symbol variation command) to the effect control unit 202A. In step S414, the main control unit 201 determines whether the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S414: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, if the main control unit 201 determines that the symbol variation time has elapsed (S414: Yes), in step S415, the main control unit 201 transmits a symbol stop command to the effect control unit 202A, and the process proceeds to step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202A. Subsequently, in step S417, the main control unit 201 sequentially transmits commands corresponding to each of the big hits (jackpot command) to the effect control unit 202A. To do. Then, when the transmission of the jackpot command for all rounds is completed, the main control unit 201 transmits the jackpot end command to the effect control unit 202A in step S418, and proceeds to the process of step S422.

  If the main control unit 201 determines in step S412 that the random number is not a big hit random number (S412: No), in step S419, the main control unit 201 transmits an outlier reach command (symbol variation command) to the effect control unit 202A. Transition to processing. In step S420, the main control unit 201 determines whether the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S420: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, if the main control unit 201 determines that the symbol variation time has elapsed (S420: Yes), in step S421, the main control unit 201 transmits a symbol stop command to the effect control unit 202A, and proceeds to the process of step S422.

  In step S422, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. When determining that the power is not turned off (S422: No), the main control unit 201 returns to the process of step S403 shown in FIG. 4 and repeats a series of processes. On the other hand, if the main control unit 201 determines that the power is turned off (S422: Yes), in step S423, the main control unit 201 transmits an end process command to the effect control unit 202A, and ends the process according to this flowchart.

  The various commands in FIGS. 4 and 5 described above correspond to the control commands of the present invention, and the main control board 310 stores the control command data in the data storage unit 311 as a history each time the various control commands are transmitted. ing. In response to the storage of the control command data, the main control board 310 updates the history data in the data storage unit 311. Note that the history data is updated when the authentication information is generated, so that the processing load on the main control board 310 can be reduced. Further, each time the control unit 202 receives a control command, the post-stage unit 202B of the peripheral board 330 stores the control command data in the post-stage storage unit 332 as a history, and updates the post-stage history data of the post-stage storage unit 332. To do.

  Next, referring to the drawing of FIG. 6 for an example of the transmission timing of the jackpot related commands (jackpot reach command, jackpot start command, jackpot command, jackpot end command) from the main control unit 201 to the effect control unit 202A in the pachinko gaming machine 100 To explain.

  The jackpot reach command is sent more frequently and randomly than the actual jackpot occurs. The jackpot start command is transmitted only once when shifting to the jackpot state when a jackpot is actually generated. The jackpot command is continuously transmitted for each round after shifting to the jackpot state. The jackpot end command is transmitted only once when all rounds of the jackpot state are completed and the normal state is entered.

  In the following, a process for a jackpot reach command (when a jackpot reach command (see step S413 in FIG. 5) or a loss reach command (see step S419 in FIG. 5) is received) and a jackpot reach process will be described.

  First, the symbol variation process by the effect control unit 202A will be described with reference to the flowchart shown in FIG. The effect control unit 202A determines whether or not a symbol variation command is received from the main control unit 201 in step S701 shown in FIG. When it is determined that the symbol variation command has not been received (S701: No), the effect control unit 202A repeats this determination process to wait for the symbol variation command to be received. On the other hand, when it is determined that the symbol variation command has been received (S701: Yes), the effect control unit 202A acquires a random effect selection random number in step S702, and in step S703, based on the acquired random number, The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202A transmits an effect start command for each variable effect to the lamp control unit 251 and the sound control unit 252, and the process proceeds to step S705.

  In step S705, the effect control unit 202A determines whether the effect time has elapsed. When it is determined that the production time has elapsed (S705: Yes), the production control unit 202A proceeds to the process of step S707. On the other hand, when it is determined that the effect time has not elapsed (S705: No), the effect control unit 202A determines whether or not a symbol stop command has been received from the main control unit 201 in step S706. And when it determines with the effect control part 202A not receiving the symbol stop command (S706: No), it returns to the process of step S705 and repeats a series of processes. On the other hand, when it is determined that the symbol control command 202A has been received (S706: Yes), in step S707, the effect control command is transmitted to the lamp control unit 251 and the voice control unit 252, and according to this flowchart. The process ends.

  Next, the big hitting process by the effect control unit 202A will be described with reference to the flowchart shown in FIG. The effect control unit 202A determines whether or not a jackpot start command (see step S416 in FIG. 5) has been received from the main control unit 201 in step S801 shown in FIG. When it is determined that the jackpot start command has not been received (S801: No), the effect control unit 202A waits for reception of the jackpot start command by repeating this determination process. On the other hand, if it is determined that the jackpot start command has been received (S801: Yes), the effect control unit 202A transmits a jackpot start processing command to the lamp control unit 251 and the voice control unit 252 in step S802, and step S803. Move on to processing.

  In step S803, the effect control unit 202A determines whether a round-by-round jackpot command (see step S417 in FIG. 5) has been received from the main control unit 201. When it is determined that the jackpot command has not been received (S803: No), the effect control unit 202A waits for reception of the jackpot command by repeating this determination process. On the other hand, if it is determined that the jackpot command has been received (S803: Yes), the effect control unit 202A has a round corresponding to the round jackpot command received by the lamp control unit 251 or the voice control unit 252 in step S804. Another processing command is transmitted, and the process proceeds to step S805.

  In step S805, the effect control unit 202A determines whether a jackpot end command (see step S418 in FIG. 5) has been received from the main control unit 201. When it is determined that the jackpot end command has not been received (S805: No), the effect control unit 202A waits for reception of the jackpot end command by repeating this determination process. On the other hand, when it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202A transmits a jackpot end processing command to the lamp control unit 251 and the voice control unit 252 in step S806, and this flowchart. The process by is terminated.

  Next, lamp control processing by the lamp control unit 251 will be described with reference to a flowchart shown in FIG. Here, a process when a production start command is received from the production control unit 202A (during symbol variation) will be described. Then, in step S901 illustrated in FIG. 9, the lamp control unit 251 determines whether or not an effect start command has been received from the effect control unit 202A. When it is determined that the effect start command has not been received (S901: No), the lamp control unit 251 waits for the reception of the effect start command by repeating this determination process. On the other hand, if the lamp control unit 251 determines that an effect start command has been received (S901: Yes), in step S902, the command-specific data prepared in advance for each command is read, and the process proceeds to step S903.

  In step S903, the lamp control unit 251 executes a selection routine for each command, sets lamp data corresponding to the received effect start command in step S904, and outputs lamp data to the lamp 261 in step S905. Then, the process proceeds to step S906. In this process, the lamp 261 is turned on or off based on the lamp data.

  In step S906, the lamp control unit 251 determines whether or not an effect stop command has been received from the effect control unit 202A. When it is determined that the effect stop command has not been received (S906: No), the lamp control unit 251 waits for the reception of the effect stop command by repeating this determination process. On the other hand, if the lamp control unit 251 determines that an effect stop command has been received (S906: Yes), in step S907, the lamp control unit 251 stops the output of the lamp data and ends the process according to this flowchart.

  Note that although the processing of the lamp control unit 251 is shown in FIG. 9, the sound control by the sound control unit 252 is almost the same as the processing of FIG. The voice control process by the voice control unit 252 may be performed by replacing “lamp data” in steps S904, S905, and S907 with “voice data” in the process of FIG.

  In the present embodiment, a case will be described in which the above-described detection target control command is a control command related to jackpot in the pachinko gaming machine 100 among the above-described plurality of types of control commands. The control command related to jackpot corresponds to the jackpot related command such as the jackpot reach command, jackpot start command, jackpot command, jackpot end command, etc. described above. In addition, one type or two or more types of detection target control commands described above can be set as detection targets.

(Control signal data format)
Next, an example of a normal control signal output from the main control unit 201 will be described.

  In FIG. 10, a normal control signal 1010 has control command data 1001 and accompanying data 1002. The control command data 1001 is data unique to each command such as a reach command, a jackpot start command, a round command, and the like. The accompanying data 1002 is data accompanying the control command data 1001, and is data necessary for processing based on the control command data 1001 such as the number of winning game balls, for example.

(Authentication information data format)
Next, an example in which an authentication information signal different from the control signal 1010 described above has authentication information will be described. In this embodiment, it is assumed that the main control unit 201 transmits an authentication information signal from the main control unit 201 to the rear stage unit 202B by outputting an authentication information signal to the rear stage unit 202B via the peripheral unit 202A. To do.

  In FIG. 11, authentication information 1020 includes an identification unit 1021 and a data unit 1022. The identification unit 1021 is set with identification data that can identify the authentication information 1020. An example of the identification data is an authentication command that is different from the control command of the control command data 1001. For example, a value such as hexadecimal 0xA0 is set. As a result, the post-stage unit 202B can identify whether or not the authentication information 1020 is based on the identification unit 1021. The authentication command is differentiated as a command system different from the control command described above.

  In the data part 1022, either one of the authentication data having any one of the above-described three types of first to third inspection values or the above-described expected value changing data is set. The data unit 1022 of the present embodiment will be described with respect to a case where authentication data or expected value change data is set, but instead, authentication data or expected value change data and other data are stored as data. The embodiment may be set in the unit 1022. Examples of other data include data accompanying an authentication command such as the accompanying data 1002 described above.

  Subsequently, the subsequent authentication result signal illustrated in FIG. 11 transmits, to the peripheral unit 202A, the subsequent authentication result information 1030 indicating the authentication result of the authentication performed by the main control unit 201 using the authentication information 1020 described above. . The latter authentication result information 1030 includes an identification unit 1031 and a result unit 1032. The identification unit 1031 is set with subsequent authentication result identification data that can identify the subsequent authentication result information 1030. Note that as the subsequent authentication result identification data, various embodiments such as diverting data set in the identification unit 1021 of the authentication information 1020 or using predetermined data can be used. The result section 1032 is set with data indicating the authentication result of the main control board 310 (main control section 201).

(Example of authentication information)
Next, an example of authentication data and expected value change data set in the data portion 1022 of the authentication information 1020 will be described below.

  As shown in FIG. 12, the data type of the authentication information 1020 includes authentication data K1 and expected value change data K2. When the data type of the authentication information 1020 is the authentication data K1, the data portion 1022 of the authentication information 1020 contains three types of first inspection value A1, second inspection value A2, and third inspection value A3 (however, A1 Authentication data having any one of ≠ A2 ≠ A3) is set.

  When the data type of the authentication information 1020 is the expected value changing data K2, the expected value changing data having either the correction value C or the coefficient value F is set in the data portion 1022 of the authentication information 1020. The correction value C is a value for changing the predetermined initial expected value. As the correction value C, for example, the correction value C generated once at the start of the pachinko gaming machine 100, at the time of the first authentication, etc. may be used repeatedly, or the correction value C is irregularly changed by generating a plurality of times. However, in the present embodiment, a case where the correction value Cn (n is an integer) is irregularly changed every time the expected value changing data is generated will be described. When the correction value C is generated a plurality of times, it becomes a value for changing the common inspection value and expected value every time it is generated.

  The coefficient value F is a value for changing the expected value changed last time. That is, the coefficient value F is a value for accumulating and changing the inspection value and the expected value every time the inspection value and the expected value are changed. As with the correction value C, the coefficient value F generated once may be used repeatedly, or the coefficient value F may be generated a plurality of times and the coefficient value Fn (n is an integer) may be changed irregularly.

  Next, an example of correspondence between three types of inspection values A, three types of expected values B, and data types K1 and K2 of authentication information 1020 and switching will be described.

  First, in the pachinko gaming machine 100, as shown in FIG. 13, for example, the stored data is determined according to manufacture and the first to third inspection values A1 to A3 generated by the main control board 310 are determined. The first to third expected values B1 to 3 corresponding to the three types of the first to third inspection values A1 to A3 are set for the rear stage portion 202B of the peripheral substrate 330. Then, the data types K1 and K2 of the authentication information 1020 shown in FIG. 12 are allocated to each of the first inspection value A1, the second inspection value A2, the first expected value B1, and the second expected value B2 of the three types. . The main control board 310 stores the first inspection value A1 and the second inspection value A2 in association with the data types K1 and K2 of the authentication information 1020. Then, the rear stage portion 202B of the peripheral substrate 330 corresponds to the data types K1 and K2 of the authentication information 1020 that are the same as the first inspection value A1 and the second inspection value A2 corresponding to the first expected value B1 and the second expected value B2. Add and remember.

  Further, the switching between the correction value C and the coefficient value F described above is assigned to the third inspection value A3 and the third expected value B3. Then, the main control unit substrate 310 detects the timing of generating or transmitting the authentication information 1020 having the third inspection value A3 as the switching timing of the correction value C and the coefficient value F. On the other hand, the rear stage portion 202B of the peripheral substrate 330 detects the timing at which the authentication information 1020 having the third inspection value A3 that matches the third expected value B3 is received as the switching timing of the correction value C and the coefficient value F. Then, the main control board 310 of the present embodiment stores the switching information H in association with the third inspection value A3. On the other hand, the rear stage portion 202B of the peripheral board 330 stores the same switching information H as that of the main control board 330 in association with the third expected value B3. Then, the main control board 310 stores the detection target control command information storing data indicating the detection target control command in association with the third inspection value A3, and the subsequent stage unit 202B sets the detection to the third expected value B3. The target control command information is stored in association with each other.

  In the present embodiment, in order to simplify the description, a case where switching is performed in the order of the correction value C and the coefficient value F will be described. For example, when starting the pachinko gaming machine 100, the main control board 310 sets the correction value C to the switching information H at an arbitrary predetermined timing, etc., and when the switching timing is detected thereafter, from the correction value C Switch to coefficient value F and set to switching information H. Similarly thereafter, the main control board 310 switches the correction value C and the coefficient value F every time the switching timing is detected. On the other hand, the rear stage portion 202B of the peripheral board 330 also refers to the switching information H in the same manner as the main control board 310, and switches the correction value C and the coefficient value F every time the switching timing is detected.

  Since the first to third inspection values A1 to A3 and the first to third expected values B1 to 3 are changed by the expected value changing data, the correspondence between the data types K1 and K2 and the switching information H is as follows. For example, it is possible to adopt various different embodiments such as updating the association every time it is changed, associating the changed value, and the initial value with each piece of information.

  Next, a modification example using the correction value Cn described above will be described. In pachinko gaming machine 100, first to third inspection values A1 to A1 correspond to first to third expected values B1 to B3 (A1 = B1, A2 = B2, A3 = B3), n is an integer, and change method Is assumed to be “+”.

  In the first change, when the main control board 310 generates the correction value C1, the main control board 310 transmits the correction value C1 to the rear stage section 202B of the peripheral board 330, and the test value generation section 312 generates it in response to detection of the change timing. The first inspection value A1 is changed with the correction value C1 to change the first inspection value A1 + C1, and the second inspection value A2 generated by the inspection value generation unit 312 is changed with the correction value C1 to generate the second inspection value A2 + C1 and inspection value. The third inspection value A3 generated by the unit 312 is changed with the correction value C1 to obtain a third inspection value A3 + C1. On the other hand, the rear stage portion 202B of the peripheral board 330 receives the correction value C1 from the main control board 310, and changes the first expected value B1 that is the initial value by the correction value C1 in response to the detection of the change timing. The expected value B1 + C1, the second expected value B2 that is the initial value is changed with the correction value C1 to change the second expected value B2 + C1, the third expected value B3 that is the initial value is changed with the correction value C1, and the third expected value B3 + C1. To do. Therefore, since the matched inspection value and the expected value are changed with the same correction value, the first inspection value A1 + C1, the second inspection value A2 + C1, the third inspection value A3 + C1 of the main control board 310 and the first expectation of the rear stage 202B. When the values B1 + C1, the second expected value B2 + C1, and the third expected value B3 + C1 are coincident with each other, the post-stage unit 202B receives the inspection values A1 + C1, A2 + C1, A3 + C1 of the authentication information received from the main control board 310. Therefore, authentication of the main control board 310 can be established.

  In the second change, when the main control board 310 generates a correction value C2 that is different from the correction value C1, the main control board 310 transmits the correction value C2 to the rear stage 202B of the peripheral board 330, and in accordance with detection of the change timing, The first inspection value A1 generated by the value generation unit 312 is changed by the correction value C2 to change the first inspection value A1 + C2, and the second inspection value A2 generated by the inspection value generation unit 312 is changed by the correction value C2 to perform the second inspection. The third inspection value A3 generated by the value A2 + C2 and the inspection value generation unit 312 is changed to the third inspection value A3 + C2 by the correction value C2. On the other hand, the rear stage portion 202B of the peripheral board 330 receives the correction value C2 from the main control board 310, and changes the first expected value B1 that is the initial value by the correction value C2 in response to the detection of the change timing. The expected value B1 + C2, the second expected value B2 that is the initial value is changed with the correction value C2, the second expected value B2 + C2, the third expected value B3 that is the initial value is changed with the correction value C2, and the third expected value B3 + C2 To do. Therefore, since the matched inspection value and the expected value are changed with the same correction value, the first inspection value A1 + C2, the second inspection value A2 + C2, the third inspection value A3 + C2 of the main control board 310 and the first expectation of the rear stage 202B. When the value B1 + C2, the second expected value B2 + C2, and the third expected value B3 + C2 coincide with each other, the subsequent stage unit 202A receives the authentication information check values A1 + C2, A2 + C2, A3 + C2 received from the main control board 310. Therefore, authentication of the main control board 310 can be established. The same change is made for the third and subsequent changes.

  Next, when the first inspection value A1 of the initial value generated by the inspection value generation unit 312 in the main control board 310 and the first expected value B0 of the initial value in the rear stage part 202B of the peripheral board 330 do not match (A1 ≠ B0), an example of changing them with the correction value Cn will be described. In order to simplify the description, the description is limited to the case where only the first inspection value A1 and the first expected values B0 and B1 are changed.

  In the first change, the main control board 310 sets the difference correction value C0 (=) between the first inspection value A1 generated by the inspection value generation unit 312 and the first expected value B0 stored in advance in the data storage unit 311 or the like. When A1-B0) is generated, the difference correction value C0 is transmitted to the rear stage section 202B of the peripheral substrate 330. On the other hand, when receiving the difference correction value C0, the rear stage portion 202B of the peripheral board 330 changes the first expected value B0, which is the initial value, to the first expected value B1 (= B0 + C0) by changing the difference correction value C0. As a result, the first expected value B1 is changed to a value that matches the first inspection value A1 of the main control board 310.

  In the second change, when the main control board 310 generates the correction value C1, the main control board 310 transmits the correction value C1 to the rear stage section 202B of the peripheral board 330, and the test value generation section 312 generates it in response to detection of the change timing. The first inspection value A1 is changed to the first inspection value A1 + C1 by changing the correction value C1. On the other hand, the rear stage portion 202B of the peripheral board 330 receives the correction value C1 from the main control board 310, and changes the first expected value B1 that was changed last time with the correction value C1 in response to the detection of the change timing. Let it be the value B1 + C1. Therefore, since the matched first inspection value A1 and first expected value B1 are changed by the same correction value C1, the first inspection value A1 + C1 of the main control board 310 and the first expected value B1 + C1 of the rear stage 202A are equal. In the case where it does, the rear stage part 202A of the peripheral board 330 can determine that the first inspection value A1 + C1 of the authentication information received from the main control board 310 is normal, so that the authentication of the main control board 310 is established. Can do. The third and subsequent changes are also made in the same manner as the second change.

  Next, when the first inspection value A0 of the initial value generated by the inspection value generation unit 312 in the main control board 310 and the first expected value B0 of the initial value in the rear stage part 202B of the peripheral board 330 do not match (A0). ≠ B0), another example of changing them with the correction value Cn will be described. In order to simplify the description, the description is limited to the case where only the first inspection value and the first expected value are changed.

  In the first change, the main control board 310 has a difference correction value C0 (=) between the first inspection value A0 generated by the inspection value generation unit 312 and the first expected value B0 stored in advance in the data storage unit 311 or the like. When A0−B0) is generated, the difference correction value C0 is stored in the data storage unit 311 or the like, and the initial first inspection value A0 is set as the first inspection value A1. Further, the rear stage portion 202B of the peripheral substrate 330 sets the initial first expected value B0 as the expected value B1. Then, when the main control board 310 adds the difference correction value C0 and the current value to create the current correction value C1, for example, the main control board 310 transmits the correction value C1 to the rear stage 202B of the peripheral board 330, and changes timing Is detected, the first inspection value A1, which is the initial value, is changed by the correction value C1 to obtain the first inspection value A1 + C1. On the other hand, the rear stage portion 202B of the peripheral board 330 receives the correction value C1 from the main control board 310, and corrects the first expected value B1 with the correction value C1 in accordance with the detection of the change timing to obtain the first expected value B1 + C1 To do. As a result, the main control board 310 generates a correction value C1 that absorbs the difference between the first inspection value A1 and the first expected value B0, and transmits the correction value C1 to the rear stage part 202B of the peripheral board 330. Correction and authentication may be performed using B0 as it is.

  Next, using the coefficient value Fn described above, the previous first inspection value A1 (n−1), second inspection value A2 (n−1), third inspection value A3 (n−1), and first expectation. A modification example in which each of the value B1 (n−1), the second expected value B2 (n−1), and the third expected value B3 (n−1) is changed will be described. In the pachinko gaming machine 100, the first to third inspection values A1 to 3 correspond to the first to third expected values B1 to 3 (A1n = B1n, A2n = B2n, A3n = B3n), n is an integer, and the change method Is assumed to be “*”.

  In the first change, when the main control board 310 generates the coefficient value F1, the main control board 310 transmits the coefficient value F1 to the rear stage section 202B of the peripheral board 330, and the inspection value generation section 312 generates it in response to detection of the change timing. The first inspection value A11 is changed by the coefficient value F1 to change the first inspection value A12 (= A11 * F1), and the second inspection value A21 generated by the inspection value generation unit 312 is changed by the coefficient value F1 to perform the second inspection. The value A22 (= A21 * F1) and the third inspection value A31 generated by the inspection value generation unit 312 are changed to the third inspection value A32 (= A31 * F1) by the coefficient value F1. On the other hand, the rear stage portion 202B of the peripheral board 330 receives the coefficient value F1 from the main control board 310, and changes the first expected value B11, which is the initial value, by the coefficient value F1 in response to detection of the change timing. The expected value B12 (= B11 * F1), the second expected value B21 that is the initial value is changed by the coefficient value F1, and the second expected value B22 (= B21 * F1) and the third expected value B31 that is the initial value are related. The value is changed by the numerical value F1 to be the third expected value B32 (= B31 * F1). Therefore, since the matched inspection value and the expected value are changed with the same coefficient value, the first inspection value A12, the second inspection value A22, the third inspection value A32 of the main control board 310 and the first expectation of the rear stage unit 202B. When the value B12, the second expected value B22, and the third expected value B32 match, the rear stage unit 202B receives the first inspection value A12, the second inspection value A22, and the second inspection value of the authentication information received from the main control board 310. Since the three inspection values A32 can be determined to be regular, the authentication of the main control board 310 can be established.

  In the second change, when the main control board 310 generates the coefficient value F2 (F1 ≠ F2), the main control board 310 transmits the coefficient value F2 to the subsequent stage 202B of the peripheral board 330, and changes the previous time according to the detection of the change timing. The first inspection value A12, the second inspection value A22, and the third inspection value A32, which are the previous inspection values for the coefficient values, are changed by the coefficient value F2, and the first inspection value A13, the second inspection value A23, and the third inspection value. A33. On the other hand, the rear stage portion 202B of the peripheral board 330 receives the coefficient value F2 from the main control board 310, and in response to detection of the change timing, the first expected value B12, the second expected value B12 that is the previous expected value for the coefficient value changed last time. The expected value B22 and the third expected value B32 are changed by the coefficient value F2 to obtain a first expected value B13, a second expected value B23, and a third expected value B33. Therefore, since the previously changed inspection value and the expected value are changed with the same coefficient value, the first inspection value A13, the second inspection value A23, the third inspection value A33 of the main control board 310 and the first portion of the rear stage 202B are changed. When the expected value B13, the second expected value B23, and the third expected value B33 match, the rear stage unit 202B receives the first inspection value A13, the second inspection value A23, and the authentication information received from the main control board 310. Since the third inspection value A33 can be determined to be regular, the authentication of the main control board 310 can be established. The third and subsequent changes are also made in the same manner as the second change.

  In the present embodiment, when the initial test value and the expected value are different values, the main control board 310 stores both the test value and the expected value. A case has been described in which expected value change data that absorbs the difference between a value and an expected value is generated. Instead, the main control board 310 stores in advance the difference data between the inspection value A and the expected value B in the data storage unit 311 and the like, and the correction value Cn and the coefficient value Fn described above based on the difference data. It can also be set as the embodiment which produces | generates. With such an embodiment, the main control board 310 can eliminate the need to store the expected value B of the rear stage section 202B.

  Subsequently, an example of the first inspection value A1 when the correction value Cn and the coefficient value Fn are switched according to the generation of the third inspection value A3 will be described. Then, it is assumed that the initial value generated by the inspection value generation unit 312 is A10, the change method is “+”, and n is an integer. In order to simplify the description, only the main control board 310 will be described.

  Since the initial setting is the correction value Cn when the pachinko gaming machine 100 is activated, the main control board 310 is the initial value generated by the inspection value generation unit 312 when the expected value change data of the correction value C1 is generated. The first inspection value A10 is changed to the first inspection value A11 (= A10 + C1) with the correction value C1. When the main control board 310 generates expected value change data for the correction value C2, the main control board 310 changes the first inspection value A10, which is the initial value, to the first inspection value A12 (= A10 + C2) using the correction value C2. Thereafter, when the main control board 310 switches from the correction value Cn to the coefficient value Fn in response to the generation of the third inspection value A3, the first inspection value A10, which is the initial value, is changed to the first inspection value A13 ( = A10 + F1) and store. When the main control board 310 generates the expected value change data for the coefficient value F2, the first inspection value A13, which is the changed inspection value, is changed to the first inspection value A14 (= A13 + F2) with the coefficient value F2 and stored. To do. Then, when the main control board 310 generates the expected value change data for the coefficient value F3, the first inspection value A14, which is the changed inspection value, is changed to the first inspection value A15 (= A13 + F3) with the coefficient value F3 and stored. To do.

  Thereafter, when the main control board 310 switches again from the coefficient value Fn to the correction value Cn in accordance with the generation of the third inspection value A3, the first inspection value A10 that is the initial value is set to the first inspection value A16 with the correction value C1. Change to (= A10 + C3) and store. Thereafter, when the main control board 310 switches from the correction value Cn to the coefficient value Fn according to the generation of the third inspection value A3, the first inspection value A15 that is the previous inspection value for coefficient value is stored in the data storage unit 311. Therefore, when the expected value changing data for the coefficient value F4 is generated, the first inspection value A15, which is the changed inspection value, is changed to the first inspection value A17 (= A15 + F4) with the coefficient value F4 and stored. . When the main control board 310 generates the expected value change data for the coefficient value F5, the first inspection value A17, which is the changed inspection value, is changed to the first inspection value A18 (= A17 + F5) with the coefficient value F5 and stored. To do.

  In the embodiment, a case where the inspection value changed by the coefficient value Fn is used as the previous inspection value for coefficient value to store and hold the previous inspection value for coefficient value to be used for the next change of the coefficient value Fn will be described. However, instead of this, similar to the correction value Cn, the initial inspection value A10 can be used every time the correction value Cn is switched to the coefficient value Fn. Further, the rear stage portion 202B of the peripheral board 330 performs the switching process similar to that of the main control board 310 described above on the expected value in response to the reception of the third inspection value.

(Processing for sending and receiving authentication information signals)
Hereinafter, an example of communication of the authentication information signal performed between the main control unit 201 and the subsequent stage unit 202B will be described. First, an example of an authentication information signal transmission procedure by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes an authenticated process shown in FIG. 14, and generates an inspection value by the inspection value generation unit 312 described above in step S1200. It memorize | stores in the memory | storage part 311, and progresses to the process of step S1201 after that. Note that the main control unit 201 of the present embodiment generates each of the first to third inspection values that are different from each other and stores them in the data storage unit 311. In addition, when the main control unit 201 generates a part of the first to third test values and the remaining test values that are not generated need to be set, the main control unit 201 changes the predetermined value to the test value that is not generated. Set.

  In step S1201, the main control unit 201 determines whether it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1201: No), the process proceeds to step S1220. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1201: Yes), the process proceeds to step S1202.

  In step S1202, the main control unit 201 determines whether to switch different data types based on, for example, a random number generation result, and determines whether to switch data types based on the determination result. If it is determined that the data type is to be switched (S1202: Yes), the main control unit 201 sets the next data type set in the type information of the data storage unit 311 as the current data type in step S1203, and then The process proceeds to step S1204. When the next data type is not set in the type information, that is, in the first process, the initial data type predetermined as an initial value in the pachinko gaming machine 100 is set as the current data type. In the following description, it is assumed that the initial data type is the data type K1 that is authentication data.

  In step S1204, the main control unit 201 determines whether or not the current data type is authentication data. When the data type is not the authentication data, that is, the expected value change data (S1204: No), the main control unit 201 proceeds to the process of step S1205. In step S1205, the main control unit 201 randomly generates the correction value C or the coefficient value F indicated by the switching information H using a predetermined generation method, and generates expected value change data having the generated value. The generated expected value changing data is stored in the data storage unit 311 or the like for generating the authentication information 1020, and then the process proceeds to step S1206. An example of a method for generating the correction value C and the coefficient value F includes generation by the generation method using a random number or a pattern table.

  When the switching information H indicates the correction value C based on the expected value change data stored in the data storage unit 311 in step S1206, the main control unit 201 determines the first three types of predetermined first types. At least one of the inspection value A1, the second inspection value A2, and the third inspection value A3 is changed by the above-described changing method (corresponding to the correction value changing means), and the switching information H is changed to the coefficient value F. In the case of showing, the previous inspection value for at least one coefficient value out of the three predetermined first inspection values A1, second inspection values A2, and third inspection values A3 is changed by the above-described change method. This corresponds to numerical value changing means), and then the process proceeds to step S1207.

  In step S1207, the main control unit 201 determines a data type predetermined for generating expected value change data as the next data type and stores it in the RAM 213 or the like, and then proceeds to the processing of step S1216. The predetermined data type is determined in advance between the main control board 310 and the rear stage 202B of the peripheral board 330.

  On the other hand, if the main control unit 201 determines in step S1204 that the data type is authentication data (S1204: Yes), the main control unit 201 generates the next time from the data type of the authentication data and the expected value change data in step S1208. The data type of the authentication information is randomly determined and stored in the RAM 213 or the like, and then the process proceeds to step S1209.

  In step S1209, the main control unit 201 extracts the test value corresponding to the next data type determined in step S1208 from the first test value A1 or the second test value A2, and stores it in the RAM 213 or the like, and in step S1210. Then, authentication data having the extracted inspection value is generated and stored in the RAM 213 or the like for generation of the authentication information 1020, and then the process proceeds to step S1216. As a result, authentication data having one of the first inspection value A1 and the second inspection value A2 is created.

  If the main control unit 201 determines in step S1202 that the data type is not to be switched (S1202: No), in step S1211, the third inspection value A3 is extracted from the three types of inspection values and stored in the RAM 213 or the like. Thereafter, the process proceeds to step S1212. In step S1212, the main control unit 201 generates authentication data having the extracted third inspection value A3 and stores it in the RAM 213 or the like, and then proceeds to the processing of step S1213. As a result, authentication data having the third inspection value A3 is created.

  In step S1213, the main control unit 201 determines whether the switching process illustrated in FIG. 15 is in operation based on whether the operation start is set in the data storage unit 311 or the like. If the main control unit 201 determines that it is operating (S1213: Yes), the main control unit 201 proceeds to the process of step S1215. On the other hand, when determining that the main control unit 201 is not operating (S1213: No), in step S1214, the main control unit 201 starts switching processing, and then proceeds to processing in step S1215. In step S1215, the main control unit 201 diverts the next data type set in the type information of the data storage unit 311 and then proceeds to the process of step S1216.

  In step S1216, the main control unit 201 sets a predetermined authentication command in the identification unit 1021 of the authentication information 1020, sets the generated authentication data or expected value change data in the data unit 1022, and sets the authentication information. 1020 is generated, the generated authentication information 1020 is stored in the data storage unit 311 or the like, and then the process proceeds to step S1217.

  In step S1217, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the subsequent unit 202B, and in step S1218, each of the encrypted authentication information 1020 is encrypted. Based on this, an authentication information signal is generated and transmitted from the main control side transmission unit 321 to the rear stage unit 202B via the peripheral unit 202A, and then the process proceeds to step S1219. If encryption is not required between the main control unit 201 and the subsequent stage unit 202B, the processing in step S1217 is deleted, and the authentication information 1020 is transmitted as it is to the subsequent stage unit 202B. In step S1219, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1207 or step S1208, and then proceeds to the process of step S1220.

  In step S1220, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. If the main control unit 201 determines that the power is not turned off (S1220: No), the process returns to step S1201 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1220: Yes), the process according to this flowchart ends.

  Next, an example of switching processing by the CPU 211 (first computer) of the main control unit 201 will be described with reference to a flowchart of FIG. In the present embodiment, the case where the CPU 211 executes the switching process and performs the above-described authenticated process and the switching process in parallel will be described. However, instead of this, the switching process is realized by other hardware. It can also be.

  When executing the switching process shown in FIG. 15, the main control unit 201 sets the operation start to the data storage unit 311 and the like in step S1301, and in step S1302, the control command transmitted from the main control unit 201 to the peripheral unit 202A is received. It is determined whether it is a detection target control command set in the detection target control command information, for example, a jackpot related command. If the main control unit 201 determines that the command is not a detection target control command (S1302: No), the main control unit 201 proceeds to the process of step S1303.

  In step S1303, the main control unit 201 determines whether or not the pachinko gaming machine 100 is powered off. If the main control unit 201 determines that the power is not turned off (S1303: No), the main control unit 201 returns to the process of step S1302, and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1303: Yes), the process according to this flowchart ends.

  When the main control unit 201 determines that the command is a detection target control command in step 1302 (S1302: Yes), the correction value set in the switching information H stored in the data storage unit 311 in step S1304. Using C or the coefficient value F as a reference, the setting is switched to the next value, the coefficient value F or the correction value C, and the setting of the switching information H is updated. Then, the process proceeds to step S1305. In step S1305, the main control unit 201 sets the operation end to the data storage unit 311 and the like, and then ends the processing according to this flowchart.

  Next, a procedure of authentication information reception processing by the CPU 21 (third computer) of the rear-stage unit 202B will be described with reference to a flowchart of FIG.

  When executing the authentication-side process illustrated in FIG. 16, the subsequent stage unit 202B determines whether or not the authentication information (authentication information signal) 1020 has been received from the main control unit 201 by the subsequent-stage reception unit 331 in step S1401. If the latter stage unit 202B determines that the authentication information 1020 has not been received (S1401: No), the process proceeds to step S1416. On the other hand, if it is determined that the authentication information 1020 has been received (S1401: Yes), the post-stage unit 202B decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, and then the step The process proceeds to S1402. If encryption is not required between the main control unit 201 and the subsequent unit 202B, the decryption process in step S1401 is deleted.

  In step S1402, the rear stage unit 202B determines whether the rear stage type information of the rear stage storage unit 332 indicates authentication data. If it is determined that the latter part 202B indicates the authentication data (S1402: Yes), the authentication data is extracted from the data part 1022 of the authentication information 1020 in step S1403, and is stored in the latter stage storage part 332 or the like. Thereafter, the process proceeds to step S1404.

  In step S1404, the rear stage unit 202B compares the authentication data with each of the three types of first expected value B1, second expected value B2, and third expected value B3 stored in the rear stage storage unit 332. Then, it is determined whether it matches any expected value. If the post-stage unit 202B determines that it matches the expected value (S1404: Yes), in step S1405, the post-stage authentication result data indicating the establishment of authentication is generated and stored in the RAM 233 or the like, and then the process of step S1406 is performed. move on.

  Whether the authentication data is the first inspection value A1 or the second inspection value A2 is determined based on whether or not the subsequent stage 202B matches the first expected value B1 or the second expected value B2 in step S1406. Determine. If the rear stage 202B determines that the first inspection value A1 or the second inspection value A2 is satisfied (S1406: Yes), in step S1407, it corresponds to the expected value that matches the first inspection value A1 or the second inspection value A2. The attached data type is specified, and the specified data type is set as the next data type in the subsequent stage type information of the subsequent stage storage unit 332, and then the process proceeds to step S1412.

  Further, if it is determined in step S1406 that it is not the first inspection value A1 or the second inspection value A2 (S1406: No), that is, if it is the third inspection value, the rear stage unit 202B is the rear stage side in step S1408. Based on whether the operation start is set in the storage unit 332 or the like, it is determined whether or not the subsequent-stage switching process shown in FIG. 17 is in operation. If the rear stage unit 202B determines that it is operating (S1408: Yes), the process proceeds to the process of step S1410. On the other hand, if it is determined that the latter part 202B is not operating (S1408: No), in step S1409, the latter part side switching process shown in FIG. 17 is started, and then the process proceeds to step S1410. In step S1410, the subsequent stage unit 202B diverts the next data type set in the subsequent stage type information of the subsequent stage storage unit 332, and then proceeds to the process of step S1412.

  On the other hand, if it is determined in step S1404 that it does not match the expected value (S1404: No), the subsequent stage unit 202B generates subsequent stage authentication result data indicating that authentication is not established in step S1411, and stores it in the RAM 233, etc. The process proceeds to step S1412.

  In step S1412, the post-stage unit 202B sets the generated post-stage authentication result data in the result unit 1032 to generate post-stage authentication result information 1030, and generates a post-stage authentication result signal to which the post-stage authentication result information 1030 is added. Transmission is performed from the rear transmission unit 339 to the peripheral unit 202A, and then the process proceeds to step S1416.

  Further, if the rear stage unit 202B determines in step S1402 that the rear stage type information does not indicate authentication data (S1402: No), that is, if it indicates expected value change data, in step S1413, The expected value change data is extracted from the data portion 1022 of the received authentication information 1020 and stored in the subsequent-stage storage unit 332 and the like, and then the process proceeds to step S1414. When the switching information H indicates the correction value C based on the expected value change data in step S1414, the subsequent stage unit 202B determines the first expected value B1, the second expected value B2, At least one initial value of the third expected value B3 is changed by a change method similar to that of the main control unit 201 (corresponding to a change unit for the rear stage correction value), and the switching information H indicates the coefficient value F. If there is, the previous expected value for at least one coefficient value of the first expected value B1, the second expected value B2, and the third expected value B3 determined in advance is changed by the above-described changing method (the latter-side coefficient value The process proceeds to step S1415. In step S1415, the subsequent stage unit 202B specifies a data type predetermined with the main control unit 201 as the next data type, and sets the specified data type as the next data type as the subsequent stage storage unit 332. Is set in the subsequent-stage type information, and then the process proceeds to step S1416.

  The post-stage unit 202B determines whether or not the pachinko gaming machine 100 is powered off in step S1416. When determining that the power is not turned off (S1416: No), the rear stage unit 202B returns to the process of step S1401 and repeats a series of processes. On the other hand, if it is determined that the power is turned off (S1416: Yes), the rear stage unit 202B ends the process according to this flowchart.

  Next, an example of the rear side switching process by the CPU 21 (third computer) of the rear stage unit 202B will be described with reference to the flowchart of FIG. In the present embodiment, as in the case of the main control unit 201, the case where the CPU 21 executes the subsequent-stage switching process and performs the above-described authentication-side process and the subsequent-stage switching process in parallel will be described. Thus, it is possible to adopt a configuration in which the rear side switching process is realized by other hardware.

  When the post-stage switching process shown in FIG. 17 is performed, the post-stage unit 202B sets an operation start to the post-stage storage unit 332 and the like in step S1501, and in step S1502, the post-stage side receive unit 331 receives from the main control unit 201. It is determined whether a control command is received based on whether a normal control signal is received. When determining that the control command has not been received (S1502: No), the subsequent stage unit 202B proceeds to the process of step S1506. On the other hand, when determining that the control command has been received (S1502: Yes), the subsequent stage unit 202B proceeds to the process of step S1503.

  In step S1503, the subsequent stage unit 202B determines whether or not the received control command is a detection target control command that is predetermined with the main control unit 201 and set in the detection target control command information. . If the subsequent stage unit 202B determines that the command is a detection target control command (S1503: Yes), the correction value C or the coefficient value F set in the switching information H stored in the subsequent stage storage unit 332 in step S1504. Is switched to the next value, the coefficient value F or the correction value C, to update the switching information H, and then the process proceeds to step S1505. In step S1505, the rear stage unit 202B sets the operation end in the rear stage storage unit 332 and the like, and then ends the process according to this flowchart.

  In addition, when it is determined in step S1503 that the command is not a detection target control command (S1503: Yes), the subsequent stage unit 202B determines in step S1506 whether the power of the pachinko gaming machine 100 is turned off. If the rear stage unit 202B determines that the power is not turned off (S1506: No), the process returns to step S1502 and repeats a series of processes. On the other hand, if it is determined that the power source is turned off (S1506: Yes), the rear stage unit 202B ends the process according to this flowchart.

  Next, a procedure for receiving various control signals, an authentication information signal, and a post-authentication result signal by the CPU 241 (second computer) of the peripheral unit 202A will be described with reference to the flowchart of FIG.

  In step S1601, the peripheral unit 202A determines whether or not the control signal 1010 has been received from the main control unit 201. When it is determined that the peripheral unit 202A has received the control signal 1010 (S1601: Yes), in step S1602, the received control signal 1010 is transferred (transmitted) from the transfer unit 351 to the subsequent stage unit 202B, and in step S1603, Predetermined processing corresponding to the control command data 1001 and accompanying data 1002 included in the received control signal 1010 is performed, and then the process proceeds to step S1608.

  On the other hand, if it is determined that the peripheral unit 202A has not received the control signal 1010 (S1601: No), it is determined in step S1604 whether authentication information (authentication information signal) 1020 has been received from the main control unit 201. To do. If the peripheral unit 202A determines that the authentication information 1020 has been received (S1604: Yes), in step S1605, the peripheral unit 202A transfers (transmits) the authentication information 1020 as it is from the transfer unit 351 to the subsequent unit 202B, and then performs the processing of step S1608. Proceed to On the other hand, if the peripheral unit 202A determines that the authentication information 1020 has not been received (S1604: No), the process proceeds to step S1606.

  In step S1606, the peripheral unit 202A determines whether or not the subsequent authentication result signal has been received from the subsequent unit 202B based on whether or not the received signal has the identification unit 1031. If the peripheral unit 202A determines that the subsequent authentication result signal has not been received (S1606: No), the peripheral unit 202A proceeds to the process of step S1608. On the other hand, if the peripheral unit 202A determines that the subsequent authentication result signal has been received (S1606: Yes), the process proceeds to step S1607.

  In step S <b> 1607, the peripheral unit 202 </ b> A refers to the result part 1032 of the received subsequent authentication result signal, and determines whether or not the subsequent authentication result signal indicates that authentication has been established. If the peripheral unit 202A determines that the subsequent authentication result indicates that the authentication is successful (S1607: Yes), the peripheral unit 202A stores the authentication result in the RAM 243 or the like, and then proceeds to the process of step S1608.

  In step S1608, the peripheral unit 202A determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power is not turned off (S1608: No), the peripheral unit 202A returns to the process of step S1601 and repeats a series of processes. On the other hand, when it is determined that the power is turned off (S1608: Yes), the peripheral unit 202A ends the process according to this flowchart.

  On the other hand, if it is determined in step S1607 that the subsequent authentication result does not indicate that the authentication is successful (S1607: No), the peripheral unit 202A outputs a notification signal from, for example, the speaker 262 (see FIG. 2) or the like in step S1609. Then, the process according to this flowchart is terminated. As for the processing of the peripheral portion 202A when the subsequent authentication result does not indicate that authentication is successful, that is, when authentication is not successful, the processing of the peripheral portion 202A is continued only by outputting a notification signal. Also good.

(Example of authentication processing procedure using authentication information)
Next, the data types K1 and K2 shown in FIG. 12 are switched, the first to third inspection values and the first to third expected values are changed, and the correction value C and the correction value F are switched to authenticate the main control board 310. An example of the procedure in the pachinko gaming machine 100 when performing the above will be described with reference to the drawings of FIGS.

  In FIG. 19, the main control board 310 that is the person to be authenticated generates the first to third inspection values in response to the activation of the pachinko gaming machine 100, and the generated first to third inspection values are stored in the data storage unit. It memorize | stores in 311 (S1700). After that, when the main control board 310 determines the data type switching and at random (S1701), the main control board 310 sets a predetermined current data type K1 (S1702). The main control board 310 randomly determines the authentication information 1020 to be generated next time from the data types K1 and K2 as the data type K2 and updates the type information (S1703), and as shown in FIG. 13, the data type K2 The authentication data of the inspection value A2 associated with is generated (S1704). Then, the main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the peripheral portion 202A of the peripheral board 330 (S1705).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A2) received from the main control board 310 to the subsequent stage part 202B (S1781).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A2) from the main control board 310 via the peripheral section 202A (S1741), the initial rear stage type information indicates the authentication data. From this, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A2) matches the three types of expected values stored in the post-stage storage unit 332, and the main data based on the determination result Post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result of the control board 310 is generated and stored in the post-stage storage unit 332 (S 1742). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S1743). Further, when authentication is established, the latter stage unit 202B corresponds to the second expected value B2 because the data for authentication is the second examination value A2, and therefore matches the second expected value B2 of the latter stage storage unit 332. The attached data type K2 is identified as the next data type, and the subsequent-stage type information of the subsequent-stage storage unit 332 is updated to indicate this data type (S1744).

  On the other hand, the peripheral part 202A of the peripheral board 330 is configured such that the control command data 1001 and the accompanying data received from the main control part 201 are received when the latter authentication result information 1030 received from the latter part 202B indicates that authentication is established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1782).

  Subsequently, when the main control board 310 determines at random the switching of the data type (S1706), the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S1707). The main control board 310 randomly determines the authentication information 1020 to be generated next time as the data type K1 from the data types K1 and K2, and updates the type information (S1708). Since the switching information H indicates the correction value, the main control board 310 randomly generates the expected value change data C1 for changing the inspection value and the expected value by a predetermined generation method (S1709). ), Authentication information 1020 (C1) having the expected value change data C1 is generated, and the authentication information 1020 (C1) is transmitted to the peripheral portion 202A of the peripheral substrate 330 (S1710). Then, since the switching information H indicates the correction value, the main control board 310 changes the initial values of the three types of inspection values by the above-described changing method based on the expected value changing data C1 (S1711). . In the present embodiment, it is assumed that the change method in the pachinko gaming machine 100 is “+”, and the main control board 310 has the first inspection value A1 + C1, the second inspection value A2 + C1, and the third inspection value A3 + C1, respectively. It has been changed.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (C1) received from the main control board 310 to the subsequent stage part 202B (S1783).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (C1) from the main control board 310 via the peripheral section 202A, the rear stage type information of the rear stage storage section 332 indicates expected value change data. Therefore, the expected value change data C1 of the data portion 1022 of the authentication information 1020 (C1) is stored in the subsequent storage unit 332 or the like (S1745). The post-stage unit 202B specifies a data type predetermined for generating the expected value change data as the next data type, and updates the post-stage type information of the post-stage storage unit 332 to indicate the data type K1. (S1746). Then, since the switching information H indicates the correction value, the rear stage unit 202B changes the initial values of the three types of expected values in the peripheral storage unit 332 based on the received expected value changing data C1 as described above. The method is changed (S1747). As a result, the peripheral board 330 is changed to the first expected value B1 + C1, the second expected value B2 + C1, and the third expected value B3 + C1 that match the inspection values of the main control board 310, respectively.

  In the present embodiment, when the subsequent stage unit 202B receives the expected value change data, the main control board 310 is not authenticated, and therefore the subsequent stage authentication result information 1030 is not transmitted to the peripheral unit 202A. For example, information indicating that the expected value change data has been received, dummy post-stage authentication result information 1030, and the like may be transmitted to the peripheral unit 202A.

  Subsequently, in FIG. 20, when the main control board 310 randomly determines that the data type is not switched (S1712), the data type K1 indicated by the type information in the data storage unit 311 is used as the next data type (S1713). ). The main control board 310 generates authentication data for the third inspection value A3 + C1 extracted from the data storage unit 311 (S1714). Then, the main control board 310 generates authentication information 1020 (A3 + C1) having the authentication data, and transmits the authentication information 1020 (A3 + C1) to the peripheral portion 202A of the peripheral board 330 (S1715). When the main control board 310 detects the transmission of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral part 202 </ b> A of the peripheral board 330 (S <b> 1716), the switching information described above. Based on H, the correction value C is switched to the coefficient value F and set in the switching information H (S1717).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A3 + C1) received from the main control board 310 to the subsequent stage part 202B (S1784).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A3 + C1) from the main control board 310 via the peripheral section 202A (S1748), the rear stage type information of the rear stage storage section 332 includes the authentication data. Therefore, it is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A3 + C1) matches the three types of expected values stored in the subsequent-stage storage unit 332, and the determination result The post-authentication result information 1030 having the post-authentication result data indicating the authentication result of the main control board 310 based on the above is generated and stored in the post-stage storage unit 332 (S1749). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S1750). Further, when authentication is established, the latter stage unit 202B uses the data type K1 indicated by the latter stage type information of the latter stage storage unit 332 as the next data type because the authentication data is the third inspection value A3 + C1 ( S1751). Then, when detecting that the detection target control command indicated by the detection target control command information is received from the main control board 310 (S1752), the rear stage unit 202B corrects based on the switching information H described above, similarly to the main control board 310. The value C is switched to the coefficient value F and set in the switching information H (S1753).

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1785).

  Subsequently, when the main control board 310 determines at random the switching of the data type (S1718), the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S1719). The main control board 310 randomly determines the authentication information 1020 to be generated next time from the data types K1 and K2 as the data type K1, and updates the type information (S1720). The main control board 310 generates authentication data for the first inspection value A1 + C1 associated with the data type K1 (S1721). Then, the main control board 310 generates authentication information 1020 (A1 + C1) having the authentication data, and transmits the authentication information 1020 (A1 + C1) to the peripheral portion 202A of the peripheral board 330 (S1722).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A1 + C1) received from the main control board 310 to the subsequent stage part 202B (S1786).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A1 + C1) from the main control board 310 via the peripheral section 202A (S1754), the rear stage type information of the rear stage storage section 332 includes the authentication data. Therefore, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C1) matches the three types of expected values stored in the subsequent storage unit 332, and the determination result The post-stage authentication result information 1030 having the post-stage authentication result data indicating the authentication result of the main control board 310 based on the above is generated and stored in the post-stage side storage unit 332 (S1755). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S1756). Further, when authentication is established, the subsequent stage unit 202B corresponds to the first expected value B1 because the data for authentication is the first inspection value A1 + C1 and matches the first expected value B1 + C1 of the rear side storage unit 332. The attached data type K1 is specified as the next data type, and the post-stage type information of the post-stage storage unit 332 is updated to indicate the data type K1 (S1757).

  Further, in the peripheral portion 202A of the peripheral board 330, when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication is established, the main control portion 201 changes the control command data 1001 and the accompanying data 1002 to the control command data 1001. When the corresponding predetermined process can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1787).

  Subsequently, when the main control board 310 randomly determines the data type switching (S1723), the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S1724). The main control board 310 randomly determines the authentication information 1020 to be generated next time as the data type K2 from the data types K1 and K2, and updates the type information (S1725). The main control board 310 generates authentication data for the second inspection value (A2 + C1) associated with the data type K2 (S1726). Then, the main control board 310 generates authentication information 1020 (A2 + C1) having the authentication data, and transmits the authentication information 1020 (A2 + C1) to the peripheral part 202A of the peripheral board 330 (S1727).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A2 + C1) received from the main control board 310 to the subsequent stage part 202B (S1788).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A2 + C1) from the main control board 310 via the peripheral section 202A (S1758), the rear stage type information of the rear stage storage section 332 includes the authentication data. Therefore, it is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A2 + C1) matches the three types of expected values stored in the subsequent-stage storage unit 332, and the determination result The post-stage authentication result information 1030 having the post-stage authentication result data indicating the authentication result of the main control board 310 based on the above is generated and stored in the post-stage side storage unit 332 (S1759). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S1760). Further, when authentication is established, the latter stage unit 202B corresponds to the second expected value B2 + C1 because the authentication data is the second inspection value A2 + C1, and therefore coincides with the second expected value B2 + C1 of the rear stage storage unit 332. The attached data type K2 is specified as the next data type, and the subsequent-stage type information of the subsequent-stage storage unit 332 is updated to indicate the data type K2 (S1761).

  Further, in the peripheral portion 202A of the peripheral board 330, when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established, the main control portion 201 changes the control command data 1001 and the accompanying data 1002 to When the corresponding predetermined processing can be executed and the subsequent authentication result information 1030 does not indicate that the authentication is successful, a notification signal is output (S1789).

  Subsequently, in FIG. 21, when the main control board 310 determines the data type switching and random (S1728), the data type K2 indicated by the type information in the data storage unit 311 is set as the current data type (S1729). . The main control board 310 randomly determines the authentication information 1020 to be generated next time from the data types K1 and K2 as the data type K1, and updates the type information (S1730). Since the main control board 310 indicates the coefficient value indicated by the switching information H, the main control board 310 randomly generates the expected value change data F1 for changing the inspection value and the expected value by a predetermined generation method ( In step S1731, authentication information 1020 (F1) including the expected value change data is generated, and the authentication information 1020 (F1) is transmitted to the peripheral portion 202A of the peripheral board 330 (S1732). And since the main control board 310 has shown the coefficient value which the switching information H shows, based on the said expected value change data F1, the last test value for coefficient values of three types of test values is changed by the above-described change method. Change (S1733). As a result, the main control board 310 is changed to the first inspection value A1 + F1, the second inspection value A2 + F1, and the third inspection value A3 + F1, respectively.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (F1) received from the main control board 310 to the rear stage part 202B (S1790).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (F1) from the main control board 310 via the peripheral section 202A, the rear stage type information of the rear stage storage section 332 indicates expected value change data. Therefore, the expected value change data F1 of the data portion 1022 of the authentication information 1020 (F1) is stored in the subsequent storage unit 332 or the like (S1762). The post-stage unit 202B specifies the data type K1 that is predetermined for generating the expected value change data as the next data type, and sets the post-stage type information of the post-stage storage unit 332 to indicate the data type K1. It is updated (S1763). Since the rear stage unit 202B indicates the coefficient value indicated by the switching information H, the previous expected value for coefficient value of the three types of expected values in the rear side storage unit 332 is described above based on the expected value change data F1. The change is made by the changed change method (S1764). As a result, the rear stage section 202B is changed to the first expected value B1 + F1, the second expected value B2 + F1, and the third expected value B3 + F1 that match the inspection values of the main control board 310.

  Subsequently, when the main control board 310 randomly determines that the data type is not switched (S1734), the main control board 310 diverts the data type K1 indicated by the type information in the data storage unit 311 as the next data type (S1735). The main control board 310 generates authentication data for the third inspection value A3 + F1 extracted from the data storage unit 311 (S1736). Then, the main control board 310 generates authentication information 1020 (A3 + F1) having the authentication data, and transmits the authentication information 1020 (A3 + F1) to the peripheral portion 202A of the peripheral board 330 (S1737). When the main control board 310 detects the transmission of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral part 202 </ b> A of the peripheral board 330 (S <b> 1738), the switching information described above. Based on H, the coefficient value F is switched to the correction value C and set in the switching information H (S1739).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A3 + C1) received from the main control board 310 to the subsequent stage part 202B (S1791).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A3 + F1) from the main control board 310 via the peripheral section 202A (S1765), the rear stage type information of the rear stage storage section 332 includes the authentication data. Therefore, it is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A3 + F1) matches the three types of expected values stored in the subsequent-stage storage unit 332, and the determination result The post-authentication result information 1030 having the post-authentication result data indicating the authentication result of the main control board 310 based on the above is generated and stored in the post-stage storage unit 332 (S1766). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S1767). Further, when the authentication is established, the latter stage unit 202B uses the data type K1 indicated by the latter stage type information of the latter stage storage unit 332 as the next data type because the authentication data is the third inspection value A3 + F1 ( S1768). Then, when the rear stage unit 202B detects reception of the detection target control command indicated by the detection target control command information from the main control board 310 (S1769), based on the switching information H described above, similarly to the main control board 310, Switching from the coefficient value F to the correction value C is set in the switching information H (S1770).

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1792). Thereafter, the same authentication process as described above is performed.

(Example of change procedure using expected value change data)
Next, an example of a change procedure when each of the rear stage 202B of the main control board 310 and the peripheral board 330 changes the inspection value and the expected value using the expected value change data will be described with reference to the drawing of FIG. explain.

  In FIG. 22, the main control board 310 generates the first to third inspection values in response to the activation of the pachinko gaming machine 100 and stores the generated first to third inspection values in the data storage unit 311 ( S1800). Then, when the main control board 310 generates authentication data having the third inspection value A3, the main control board 310 generates authentication information 1020 (A3) having the authentication data and transmits it to the peripheral portion 202A of the peripheral board 330 (S1801). ). On the other hand, the peripheral unit 202A transfers (transmits) the authentication information 1020 (A3) received from the main control board 310 to the subsequent unit 202B (S1851). Then, the post-stage unit 202B authenticates the main control board 310 based on the third inspection value A3 of the authentication information 1020 (A3) received from the main control board 310, and sends the post-stage authentication result data indicating the authentication result to the peripheral part. It is transmitted to 202A (S1881). In addition, the peripheral unit 202A enables execution of a predetermined process corresponding to the control command when the post-authentication result data received from the post-stage unit 202B indicates that authentication has been established.

  When the main control board 310 transmits a non-detection target control command to the peripheral unit 202A to control the peripheral board 330, the command is not a detection target control command, so that the correction value C and the coefficient value F are switched. No (S1802). On the other hand, the peripheral unit 202A transfers (transmits) the non-detection target control command received from the main control board 310 to the subsequent stage unit 202B and performs a predetermined process corresponding to the non-detection target control command (S1852). Then, since the received control command is not the detection target control command, the subsequent stage unit 202B does not switch between the correction value C and the coefficient value F, and discards the received control command (S1882).

  When the main control board 310 transmits a detection target control command to the peripheral portion 202A of the peripheral board 330 in order to control the peripheral board 330 (S1803), the command is a detection target control command. The correction value C is switched to the coefficient value F (S1804). On the other hand, when the peripheral unit 202A receives the detection target control command from the main control board 310, the peripheral unit 202A transfers (transmits) the control command to the subsequent stage unit 202B and performs a predetermined process corresponding to the detection target control command (S1853). ). Then, the subsequent stage unit 202B switches from the correction value C to the coefficient value F based on the switching information H because the received control command is a detection target control command (S1883). As a result, the rear stage 202B of the main control board 310 and the peripheral board 330 is switched to the coefficient value F.

  When the main control board 310 generates the expected value change data having the coefficient value F, the main control board 310 stores the expected value change data in the data storage unit 311 and the like, and transmits it to the peripheral part 202A of the peripheral board 330 (S1805). . The main control board 310 changes each of the first to third inspection values with the expected value change data stored in the data storage unit 311 or the like (S1806). On the other hand, the peripheral part 202A of the peripheral board 330 transfers (transmits) the expected value change data received from the main control board 310 to the subsequent stage part 202B (S1854). Then, the rear stage unit 202B stores the received expected value change data in the rear stage side storage unit 332 and the like, and changes the first to third expected values with the expected value change data (S1885).

  Further, when generating the authentication data having the third inspection value A3, the main control board 310 generates the authentication information 1020 (A3) having the authentication data and transmits it to the peripheral part 202A of the peripheral board 330 (S1811). ). On the other hand, the peripheral portion 202A of the peripheral substrate 330 transfers (transmits) the third inspection value A3 latter stage portion 202B of the authentication information 1020 (A3) received from the main control substrate 310 (S1861). Then, the post-stage unit 202B authenticates the main control board 310 based on the third inspection value A3 of the authentication information 1020 (A3) received from the main control board 310, and sends the post-stage authentication result data indicating the authentication result to the peripheral part It transmits to 202A (S1891). In addition, the peripheral unit 202A enables execution of a predetermined process corresponding to the control command when the post-authentication result data received from the post-stage unit 202B indicates that authentication has been established.

  Thereafter, when an unauthorized detection target control command is transmitted to the peripheral portion 202A of the peripheral board 330, the peripheral portion 202A transmits the received unauthorized detection target control command to the subsequent stage portion 202B, and the detection target control command is transmitted to the peripheral portion 202A. Corresponding predetermined processing is performed (S1862). Then, since the received control command is a detection target control command, the subsequent stage unit 202B switches from the coefficient value F to the correction value C based on the switching information H (S1892). As a result, the switching information H of the rear stage unit 202B indicates the correction value C and does not match the coefficient value F indicated by the switching information H of the main control board 310 (S1893). Through the above processing, the subsequent stage unit 202A can no longer establish authentication of the main control board 310 and can detect fraud.

  According to the pachinko gaming machine 100 described above, since the main control board 310 generates a predetermined inspection value among the first to third inspection values, the inspection to be generated on the main control board 310 is generated. Since it is not necessary to store the value in advance, an increase in the amount of data stored in advance for authentication of the main control unit 201 in the pachinko gaming machine 100 can be suppressed. Further, even if the data of the main control board 310 is illegally analyzed, the generated inspection value is not stored, so that it is possible to contribute to the prevention of unauthorized analysis for the authentication of the main control board 310. Then, the main control unit 201 associates two types of authentication information with each of the first inspection value and the second inspection value of the three types of inspection values, and the first inspection value or the second inspection value. Since the authentication data is generated by the above, the authentication information 1020 having the authentication data is generated and transmitted to the subsequent stage 202B, the subsequent stage 202B associates the data type with the expected value. When the inspection value of the authentication information 1020 matches the expected value, the authentication of the main control unit 201 can be established and the data type of the authentication information 1020 to be received next time can be specified. An analyst can be prevented from using the authentication information 1020 illegally. Further, the main control unit 201 switches between a correction value and a coefficient value that are selectively used for the expected value change data according to the generation or transmission of the authentication information 1020 having the third inspection value, and the rear stage unit 202B Since the coefficient value F is switched in response to the reception of the authentication information 1020 having the third inspection value, the switching method and switching timing of the inspection value and the expected value can be made irregular. Analysis by a simple analyst can be made even more difficult. Then, the post-stage unit 202B can synchronize with the switching of the main control unit 201 by switching the correction value C and the coefficient value F in response to reception of the authentication information 1020 having the third inspection value. The inspection value and the expected value can be aligned and changed between the part 201 and the subsequent stage part 202B, and the analysis by an unauthorized analyst can be made even more difficult. Since only one type of authentication information 1020 has to be used, the addition to the conventional command system can be minimized and the processing of the main control unit 201 can be prevented from becoming complicated. Furthermore, since the latter part 202B can detect that the authentication information 1020 has been used illegally by the fraud analyst by the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since three types of inspection values can be stored in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. In addition, the peripheral unit 202A transmits the authentication information 1020 from the main control unit 201 to the subsequent stage unit 202B as it is, so that the peripheral unit 202A can perform the predetermined process and the subsequent stage unit 202B can perform the authentication process. Therefore, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, even if the data used for authentication and authentication is changed with one type of authentication information 1020, the authentication information 1020 and the unauthorized analysis of the change can be made difficult.

  In the pachinko gaming machine 100 described above, the main control board 310 generates at least one of the first to third inspection values based on the stored data in response to the activation of the pachinko gaming machine 100. Therefore, it is not necessary to store the generated inspection value in the data storage unit 311 in advance, and the authentication of the main control board 310 can be performed immediately after the pachinko gaming machine 100 is activated. This can contribute to the improvement of the authentication strength of 1020.

  In the pachinko gaming machine 100 described above, the main control unit 201 and the subsequent stage unit 202B store the inspection value and the expected value changed by the coefficient value expected value change data as the coefficient value previous inspection value and the coefficient value previous expected value. In addition, when the correction value was switched to the coefficient value again, the last changed inspection value and expected value were continuously changed. Therefore, analysis by an unauthorized analyst can be made even more difficult.

  In the pachinko gaming machine 100 described above, the main control unit 201 and the subsequent stage unit 202B associate the switching timing of the correction value C and the coefficient value F with the detection of a detection target control command determined in advance from a plurality of types of control commands. As a result, the interval of the switching timing can be made irregular and the correction value C and the coefficient value F can be switched between the main control unit 201 and the subsequent stage unit 202B. Analysis can be made even more difficult.

  In the pachinko gaming machine 100 described above, for example, the jackpot related command in the pachinko gaming machine 100 such as a jackpot reach command, a jackpot start command, a jackpot command, a jackpot end command, etc. is set as a detection target control command. Since an unauthorized jackpot related command is transmitted to the peripheral portion 202A because it is easily used illegally, the latter stage portion 202B detects it as a detection target control command and switches between the correction value C and the coefficient value F. The correction value C and the coefficient value F can be made inconsistent between the main control unit 201 and the subsequent stage unit 202B. Therefore, it is possible to contribute to improving the accuracy of detecting the occurrence of fraud.

  Further, in the above-described embodiment, the main control board 310, when detecting the detection target control command, when the number of regenerated authentication information having the third inspection value satisfies a predetermined switching condition, The rear stage unit 202B of the peripheral board 330 detects the reception of the detection target control command from the main control unit 201, and the number of times the authentication information having the third inspection value is received again satisfies the same switching condition as the main control unit. When it is satisfied, the correction value C and the coefficient value F can be switched. By adopting such a configuration, the timing for switching between the correction value C and the coefficient value F can be further complicated.

[Example 2]
Hereinafter, a second embodiment of the pachinko gaming machine 100 described above will be described. In addition, about the same part as the structure mentioned above, the same code | symbol is attached | subjected and only a different part is demonstrated in detail.

(Functional configuration of main control board and peripheral board)
First, the pachinko gaming machine 100 includes the control unit 200 shown in FIG. The control unit 200 includes a main control unit 201, an effect control unit (peripheral unit) 202A, a rear stage unit 202B, and a prize ball control unit 203. As shown in FIG. 23, the pachinko gaming machine 100 includes a main control board 310 having a function as the main control unit 201, and a peripheral board 330 having the above-described effect control unit 202A and the rear stage unit 202B. Is configured. The main control board 310 is electrically connected so as to communicate with the peripheral board 330.

  The main control board 310 includes the data storage unit 311, the inspection value generation unit 312, the determination unit 314, the authentication data generation unit 317, the expected value change data switching unit 318, the expected value change data generation unit 319, and the authentication information. A generation unit 320, a main control side transmission unit 321, an update unit 322, a correction value change unit 323, a coefficient value change unit 324, a control command detection unit 325, and a selection unit 326 are configured.

  The selection unit 326 corresponds to the selection unit of the present invention, and when the type information indicates authentication data, the inspection value generation unit 312 generates and stores it in the data storage unit (inspection value storage unit) 311. One test value is randomly selected from the first test value, the second test value, and the third test value. The selection unit 326 randomly selects one inspection value A using a random number or the like. The selection method of the selection unit 326 preferably has an irregular selection pattern in order to prevent unauthorized analysis.

  The determination unit 314 described above authenticates the main control board 310 next time with the data types K1 and K2 (see FIG. 13) associated with the first inspection value A1 or the second inspection value A2 selected by the selection unit 326. The data type of the information 1020 is determined. Specifically, when the first inspection value A1 is selected, the next time is determined as the data type K1, and when the second inspection value A2 is selected, the next time is determined as the data type K2. Then, when the selection unit 326 selects the third inspection value A3, the determination unit 314 determines a predetermined data type as the next data type as in the first embodiment. The authentication data generation unit 317 described above generates authentication data having one inspection value selected by the selection unit 326 when the type information indicates authentication data.

  When the pachinko gaming machine 100 according to the second embodiment uses the three types of inspection values for the authentication of the main control board 310 as in the first embodiment, the main control board 310 changes the inspection values with the expected value change data. Therefore, the rear stage 202B of the peripheral board 330 acquires the expected value change data from the main control board 310, and changes the expected value corresponding to the inspection value with the expected value change data. A configuration is adopted in which the main control board 310 is authenticated based on the inspection value and the expected value. Since the three types of inspection values are generated by the main control board 310 after the pachinko gaming machine 100 is started, it is not necessary to store in advance the inspection values used by the main control board 310 for authentication. Analysis can be made difficult. Further, since the inspection value is changed by generating the expected value changing data by switching the correction value and the coefficient value, it is possible to make unauthorized analysis difficult. Therefore, even if the pachinko gaming machine 100 authenticates with one type of authentication information, it can make it difficult to illegally analyze the authentication data, so that security can be improved.

  23, the rear stage unit 202B of the peripheral board 330 shown in FIG. 23 is similar to the first embodiment. The rear stage reception unit 331, the rear stage storage unit 332, the rear stage authentication result data generation unit 333, and the rear stage transmission unit 334 described above. The rear stage expected value change data switching section 335, the rear stage correction value changing section 336, the rear stage coefficient value changing section 337, the specifying section 338, and the rear stage control command detecting section 339 are configured. Similarly to the first embodiment, the peripheral portion 202A also includes the transfer unit 351, the peripheral side receiving unit 352, and the processing unit 353 described above. As described above, the peripheral substrate 330 can be realized by the same configuration as that of the first embodiment, and thus the description thereof is omitted.

  Also in the second embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 241 of the peripheral part (effect control unit) 202A of the peripheral board 330 is the second computer in the claims of the peripheral board 330. A case will be described in which the CPU 21 of the rear stage unit 202B functions as the third computer in the claims. The ROM 212 of the main control board 310 includes the inspection value generation means, the determination means, the authentication data generation means, the expected value change data switching means, the expected value change data generation means, and the authentication. Stores a main control side authentication program for functioning as various means such as information generation means, main control side transmission means, update means, correction value change means, coefficient value change means, control command detection means, selection means, etc. ing. The ROM 242 of the peripheral portion 202A of the peripheral board 330 stores a peripheral side authentication program for causing the second computer to function as various means such as transfer means, peripheral side receiving means, and processing means. Yes. Further, the ROM 22 of the rear stage 202B of the peripheral board 330 includes the third computer in the rear side receiving means, the rear stage authentication result data generating means, the rear stage side transmitting means, the rear stage side expected value changing data switching means, and the rear stage. A post-stage side authentication program for functioning as various means such as side correction value changing means, post-stage side coefficient value changing means, specifying means, and post-stage side control command detecting means is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program, the peripheral side authentication program, and the subsequent stage side authentication program.

(Processing for sending and receiving authentication information signals)
Hereinafter, an example of communication of the authentication information signal performed between the main control unit 201 and the subsequent stage unit 202B will be described. First, an example of the authentication information signal transmission procedure 2 by the CPU 211 (first computer) of the main control unit 201 will be described with reference to the flowchart of FIG.

  When the power of the pachinko gaming machine 100 is turned on (turned on), the main control unit 201 executes the authenticated process shown in FIG. 24, and in step S1900, the above-described inspection value generation unit 312 generates an inspection value to generate data. It memorize | stores in the memory | storage part 311, and progresses to the process of step S1901 after that. Note that the main control unit 201 of the present embodiment generates each of the first to third inspection values that are different from each other and stores them in the data storage unit 311. In addition, when the main control unit 201 generates a part of the first to third test values and the remaining test values that are not generated need to be set, the main control unit 201 changes the predetermined value to the test value that is not generated. Set.

  In step S1901, the main control unit 201 determines whether it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1901: No), the main control unit 201 proceeds to the process of step S1918. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1901: Yes), the process proceeds to step S1902.

  In step S1902, the main control unit 201 sets the next data type set in the type information of the data storage unit 311 as the current data type, and then proceeds to the processing of step S1903. When the next data type is not set in the type information, that is, in the first process, the initial data type predetermined as an initial value in the pachinko gaming machine 100 is set as the current data type. In the following description, it is assumed that the initial data type is the data type K1 that is authentication data.

  In step S1903, the main control unit 201 determines whether the current data type is authentication data. When the data type is not the authentication data, that is, the expected value change data (S1903: No), the main control unit 201 proceeds to the process of step S1904. In step S1904, the main control unit 201 randomly generates the correction value C or the coefficient value F indicated by the switching information H using a predetermined generation method, and generates expected value change data having the generated value. The generated expected value change data is stored in the data storage unit 311 or the like for generating the authentication information 1020, and then the process proceeds to step S1905. An example of a method for generating the correction value C and the coefficient value F includes generation by the generation method using a random number or a pattern table.

  When the switching information H indicates the correction value C based on the expected value change data stored in the data storage unit 311 in step S1905, the main control unit 201 determines three types of predetermined first types. At least one initial value of one inspection value A1, second inspection value A2, and third inspection value A3 is changed by the above-described changing method (corresponding to correction value changing means), and switching information H is a coefficient value. When F is shown, at least one change correction value among the three types of the first inspection value A1, the second inspection value A2, and the third inspection value A3 determined in advance is changed by the above-described changing method ( This corresponds to coefficient value changing means), and then the process proceeds to step S1906.

  In step S1906, the main control unit 201 determines a data type predetermined for generating expected value change data as the next data type and stores it in the RAM 213 or the like, and then proceeds to the process of step S1914. The predetermined data type is determined in advance between the main control board 310 and the rear stage 202B of the peripheral board 330.

  On the other hand, when the main control unit 201 determines in step S1903 that the data type is authentication data (S1903: Yes), in step S1907, the three types of first inspection values stored in the data storage unit 311 are displayed. One inspection value is randomly selected from the second inspection value and the third inspection value and stored in the RAM 213 or the like. In step S1908, authentication data having the selected inspection value is generated and stored in the RAM 213 or the like. Thereafter, the process proceeds to step S1909. As a result, authentication data having any one of the three types of inspection values is created.

  In step S1909, the main control unit 201 determines whether or not the inspection value selected in step S1907 is the third inspection value. If the main control unit 201 determines that the value is not the third inspection value (S1909: No), the data type associated with the selected first inspection value or the second inspection value is generated next time in step S1910. The data type of the authentication information 1020 is determined, and then the process proceeds to step S1914. On the other hand, when the main control unit 201 determines that it is the third inspection value (S1909: Yes), the above-described diagram is based on whether or not the operation start is set in the data storage unit 311 or the like in step S1911. It is determined whether or not the switching process shown in FIG. If the main control unit 201 determines that it is operating (S1911: Yes), the main control unit 201 operates the switching process, and thus proceeds to the process of step S1913. On the other hand, if the main control unit 201 determines that it is not in operation (S1911: No), in step S1912, the main control unit 201 starts the switching process shown in FIG. 15, and then proceeds to the process of step S1913. Note that the switching process shown in FIG. 15 can be used as it is, and thus detailed description thereof is omitted. In step S1913, the main control unit 201 diverts the next data type set in the type information of the data storage unit 311 and then proceeds to the process of step S1914.

  In step S1914, the main control unit 201 sets a predetermined authentication command in the identification unit 1021 of the authentication information 1020, sets the generated authentication data in the data unit 1022, and generates authentication information 1020. The generated authentication information 1020 is stored in the data storage unit 311 or the like, and then the process proceeds to step S1915.

  In step S1915, the main control unit 201 encrypts the generated authentication information 1020 using a predetermined encryption method with the subsequent stage unit 202B. In step S1916, the main control unit 201 stores each of the encrypted authentication information 1020. Based on this, an authentication information signal is generated and transmitted from the main control side transmission unit 321 to the rear stage unit 202B via the peripheral unit 202A, and then the process proceeds to step S1917. If encryption is not required between the main control unit 201 and the subsequent stage unit 202B, the process of step S1915 is deleted, and the authentication information 1020 is transmitted to the subsequent stage unit 202B as it is. In step S1917, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1906 or step S1910, and then proceeds to the process of step S1918.

  In step S1918, the main control unit 201 determines whether or not the pachinko gaming machine 100 is turned off. If the main control unit 201 determines that the power is not turned off (S1918: No), the main control unit 201 returns to the process of step S1901 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1918: Yes), the process according to this flowchart ends.

  Subsequently, the control signal and the subsequent authentication result signal received by the CPU 241 (second computer) in the peripheral portion 202A of the peripheral board 330, and the authentication performed by the CPU 21 (third computer) in the rear portion 202B. The procedure of the information signal reception process can use the process shown in FIG. 18 of the first embodiment and the authentication side process shown in FIG.

(Example 2 of authentication processing procedure using authentication information)
Next, the data types K1 and K2 shown in FIG. 12 are switched, the first to third inspection values and the first to third expected values are changed, and the correction value C and the coefficient value F are switched to authenticate the main control board 310. An example of the procedure in the pachinko gaming machine 100 when performing the above will be described with reference to the drawings of FIGS.

  In FIG. 25, the main control board 310 that is the person to be authenticated generates first to third inspection values in response to the activation of the pachinko gaming machine 100, and the generated first to third inspection values are stored in the data storage unit. 311 is stored (S2000). Thereafter, the main control board 310 sets a predetermined data type K1 for this time (S2001). The main control board 310 randomly selects one second inspection value A2 from the three types of inspection values in the data storage unit 311 (S2002), and generates authentication data for the second inspection value A2 (S2003). . The main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the peripheral portion 202A of the peripheral board 330 (S2004). Then, as shown in FIG. 13, the main control board 310 determines the data type K2 associated with the selected second inspection value A2, the authentication information 1020 to be generated next time as the data type K2, and the type information. Update (S2005).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A2) received from the main control board 310 to the subsequent stage part 202B (S2081).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A2) from the main control board 310 via the peripheral section 202A (S2041), the initial rear stage type information indicates the authentication data. From this, it is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A2) matches the three types of expected values stored in the post-stage storage unit 332, and the main data based on the determination result Post-stage authentication result information 1030 having post-stage authentication result data indicating the authentication result of the control board 310 is generated and stored in the post-stage storage unit 332 (S2042). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S2043). Then, when authentication is established, the latter stage unit 202B corresponds to the second expected value B2 because the authentication data is the second inspection value A2, and therefore matches the second expected value B2 of the rear stage storage unit 332. The attached data type K2 is specified as the next data type, and the subsequent-stage type information of the subsequent-stage storage unit 332 is updated so as to indicate this data type (S2044).

  On the other hand, the peripheral part 202A of the peripheral board 330 is configured such that the control command data 1001 and the accompanying data received from the main control part 201 are received when the latter authentication result information 1030 received from the latter part 202B indicates that authentication is established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S2082).

  Subsequently, the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S2006). Since the type information indicates the data type K2 and the switching information H indicates the correction value, the main control board 310 randomly generates the correction value C1 by a predetermined generation method, and sets the correction value C1 to the correction value C1. Based on this, the expected value changing data C1 for changing the inspection value and the expected value is generated (S2007). The main control board 310 generates authentication information 1020 (C1) having the expected value change data C1, and transmits the authentication information 1020 (C1) to the peripheral portion 202A of the peripheral board 330 (S2008). Then, the main control board 310 updates the authentication information 1020 to be generated next time as the data type K1 for the predetermined data type K1, and updates the type information (S2009). Then, since the switching information H indicates the correction value, the main control board 310 changes the initial values of the three types of inspection values by the above-described changing method based on the expected value changing data C1 (S2010). . Thereby, in this embodiment, since it is premised that the change method in the pachinko gaming machine 100 is “+”, the main control board 310 has the first inspection value A1 + C1, the second inspection value A2 + C1, and the third inspection value. This is changed to A3 + C1, respectively.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (C1) received from the main control board 310 to the subsequent stage part 202B (S2083).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (C1) from the main control board 310 via the peripheral section 202A, the rear stage type information of the rear stage storage section 332 indicates expected value change data. Therefore, the expected value change data C1 of the data portion 1022 of the authentication information 1020 (C1) is stored in the subsequent storage unit 332 or the like (S2045). Then, the post-stage unit 202B specifies the data type K1 that is predetermined for generating the expected value change data as the next data type, and the post-stage type of the post-stage storage unit 332 indicates the data type K1. Information is updated (S2046). Then, since the switching information H indicates the correction value, the rear stage unit 202B changes the initial values of the three types of expected values of the rear side storage unit 332 based on the received expected value change data C1 as described above. The method is changed (S2047). As a result, the rear stage 202B has been changed to the first expected value B1 + C1, the second expected value B2 + C1, and the third expected value B3 + C1 that match the inspection values of the main control board 310, respectively.

  In the present embodiment, when the subsequent stage unit 202B receives the expected value change data, the main control board 310 is not authenticated, and therefore the subsequent stage authentication result information 1030 is not transmitted to the peripheral unit 202A. For example, information indicating that the expected value change data has been received, dummy post-stage authentication result information 1030, and the like may be transmitted to the peripheral unit 202A.

  Subsequently, in FIG. 26, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S2011). The main control board 310 randomly selects one third inspection value A3 + C1 from the three types of inspection values in the data storage unit 311 (S2012), and generates authentication data for the third inspection value A3 + C1 (S2013). . The main control board 310 generates authentication information 1020 (A3 + C1) having the authentication data, and transmits the authentication information 1020 (A3 + C1) to the peripheral part 202A of the peripheral board 330 (S2014). Then, the main control board 310 diverts the data type K1 indicated by the type information in the data storage unit 311 as the next data type (S2015). When the main control board 310 detects transmission of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral part 202 </ b> A of the peripheral board 330 (S <b> 2016), the switching information described above. Based on H, the correction value C is switched to the coefficient value F and set in the switching information H (S2017).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A3 + C1) received from the main control board 310 to the subsequent stage part 202B (S2084).

  On the other hand, when the rear stage part 202B of the peripheral board 330 receives the authentication information 1020 (A3 + C1) from the main control board 310 (S2048), this time indicates the data for authentication, and therefore the data part of the authentication information 1020 (A3 + C1). It is determined whether or not the authentication data 1022 and the three types of expected values stored in the subsequent storage unit 332 match, and the subsequent authentication result indicating the authentication result of the main control board 310 based on the determination result The subsequent authentication result information 1030 having data is generated and stored in the subsequent storage unit 332 (S2049). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S2050). When the authentication is established, the latter stage unit 202B uses the data type K1 indicated by the latter stage type information of the latter stage storage unit 332 as the next data type because the authentication data is the third inspection value A3 + C1 ( S2051). Then, similarly to the main control board 310, the rear stage unit 202B, when receiving the detection target control command indicated by the detection target control command information from the main control board 310 (S2052), corrects based on the switching information H described above. The value C is switched to the coefficient value F and set in the switching information H (S2053).

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S2085).

  Subsequently, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S2018). The main control board 310 randomly selects one first inspection value A1 from the three types of inspection values in the data storage unit 311 (S2019), and generates authentication data for the first inspection value A1 + C1 (S2020). . The main control board 310 generates authentication information 1020 (A1 + C1) having the authentication data, and transmits the authentication information 1020 (A1 + C1) to the peripheral portion 202A of the peripheral board 330 (S2021). Then, the main control board 310 determines the data type K1 associated with the selected first inspection value A1 + C1 as the data type K1 for the authentication information 1020 to be generated next time, and updates the type information (S2022).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A1 + C1) received from the main control board 310 to the subsequent stage part 202B (S2086).

  On the other hand, when the rear stage part 202B of the peripheral board 330 receives the authentication information 1020 (A1 + C1) from the main control board 310 via the peripheral part 202A (S2054), the authentication information 1020 indicates the authentication data this time. It is determined whether or not the authentication data in the data portion 1022 of (A1 + C1) matches the three types of expected values stored in the subsequent storage unit 332, and authentication of the main control board 310 based on the determination result Post-stage authentication result information 1030 having post-stage authentication result data indicating the result is generated and stored in the post-stage storage unit 332 (S2055). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S2056). Then, when authentication is established, the subsequent stage unit 202B corresponds to the first expected value B1 + C1 because the data for authentication is the first inspection value A1 + C1 and matches the first expected value B1 + C1 of the rear side storage unit 332. The attached data type K1 is identified as the next data type, and the post-stage type information of the post-stage storage unit 332 is updated to indicate the data type K1 (S2057).

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S2087).

  Subsequently, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S2023). The main control board 310 randomly selects one second inspection value A2 + C1 from the three types of inspection values in the data storage unit 311 (S2024), and generates authentication data for the inspection value A2 + C1 (S2025). The main control board 310 generates authentication information 1020 (A2 + C1) having the authentication data, and transmits the authentication information 1020 (A2 + C1) to the peripheral portion 202A of the peripheral board 330 (S2026). Then, the main control board 310 updates the authentication information 1020 to be generated next time as the data type K2 for the data type K2 associated with the selected second inspection value A2 + C1 and updates the type information (S2027).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A2 + C1) received from the main control board 310 to the subsequent stage part 202B (S2088).

  On the other hand, when the rear stage part 202B of the peripheral board 330 receives the authentication information 1020 (A2 + C1) from the main control board 310 via the peripheral part 202A (S2058), the authentication information 1020 indicates the authentication data this time. It is determined whether or not the authentication data in the data portion 1022 of (A2 + C1) matches the three types of expected values stored in the subsequent storage unit 332, and the authentication of the main control board 310 based on the determination result Post-stage authentication result information 1030 having post-stage authentication result data indicating the result is generated and stored in the post-stage storage unit 332 (S2059). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S2060). Since the authentication data is the second inspection value A2 + C1 when the authentication is established, the rear stage unit 202B matches the second expected value B2 + C1 of the rear side storage unit 332, and is therefore associated with the second expected value B2 + C1. The data type K2 is identified as the next data type, and the latter-stage type information of the latter-stage storage unit 332 is updated so as to indicate the data type K2 (S2061).

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S2089).

  Subsequently, in FIG. 27, the main control board 310 sets the data type K2 indicated by the type information in the data storage unit 311 as the current data type (S2028). Since the type information indicates the data type K2 and the switching information H indicates the type information, the main control board 310 randomly generates the coefficient value F1 by a predetermined generation method, and the coefficient value F1. The expected value changing data F1 for changing the inspection value and the expected value is generated based on (S2029). The main control board 310 generates authentication information 1020 (F1) having the expected value change data F1, and transmits the authentication information 1020 (F1) to the peripheral portion 202A of the peripheral board 330 (S2030). Then, the main control board 310 updates the type information of the predetermined data type K1 by determining the authentication information 1020 to be generated next time as the data type K1 (S2031). And since the main control board 310 has shown the coefficient value which the switching information H shows, based on the said expected value change data F1, the last test value for coefficient values of three types of test values is changed by the above-described change method. Change (S2032). As a result, the main control board 310 is changed to the first inspection value A1 + F1, the second inspection value A2 + F1, and the third inspection value A3 + F1, respectively.

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (C2) received from the main control board 310 to the rear stage part 202B (S2090).

  On the other hand, when the rear stage part 202B of the peripheral board 330 receives the authentication information 1020 (F1) from the main control board 310 via the peripheral part 202A, this time indicates the expected value change data, so the authentication information 1020 ( The expected value changing data F1 of the data portion 1022 of F1) is stored in the subsequent storage unit 332 or the like (S2062). The post-stage unit 202B specifies the data type K1 that is predetermined for generating the expected value change data as the next data type, and sets the post-stage type information of the post-stage storage unit 332 to indicate the data type K1. Update (S2063). Since the rear stage unit 202B indicates the coefficient value indicated by the switching information H, the previous expected value for coefficient value of the three types of expected values in the rear side storage unit 332 is described above based on the expected value change data F1. The change is made by the changed change method (S2064). As a result, the rear stage section 202B is changed to the first expected value B1 + F1, the second expected value B2 + F1, and the third expected value B3 + F1 that match the inspection values of the main control board 310.

  Subsequently, the main control board 310 sets the data type K1 indicated by the type information in the data storage unit 311 as the current data type (S2033). The main control board 310 randomly selects one third inspection value A3 + F1 from the three types of inspection values in the data storage unit 311 (S2034), and generates authentication data for the third inspection value A3 + F1 (S2035). . The main control board 310 generates authentication information 1020 (A3 + F1) having the authentication data, and transmits the authentication information 1020 (A3 + F1) to the peripheral part 202A of the peripheral board 330 (S2036). Then, the main control board 310 diverts the data type K1 indicated by the type information in the data storage unit 311 as the next data type (S2037). When the main control board 310 detects the transmission of the jackpot start command, which is the detection target control command indicated by the detection target control command information in the data storage unit 311, to the peripheral part 202 </ b> A of the peripheral board 330 (S <b> 2038), the switching information described above. Based on H, the coefficient value F is switched to the correction value C and set in the switching information H (S2039).

  On the other hand, the peripheral part 202A of the peripheral board 330 transfers the authentication information 1020 (A3 + F1) received from the main control board 310 to the subsequent stage part 202B (S2091).

  On the other hand, when the rear stage section 202B of the peripheral board 330 receives the authentication information 1020 (A3 + F1) from the main control board 310 (S2065), the data section of the authentication information 1020 (A3 + F1) is shown because the authentication data is shown this time. It is determined whether or not the authentication data 1022 and the three types of expected values stored in the subsequent storage unit 332 match, and the subsequent authentication result indicating the authentication result of the main control board 310 based on the determination result The subsequent authentication result information 1030 having data is generated and stored in the subsequent storage unit 332 (S2066). Then, the post-stage unit 202B transmits a post-stage authentication result signal to which the post-stage authentication result information 1030 is added to the peripheral part 202A of the peripheral board 330 (S2067). When the authentication is established, the latter stage unit 202B uses the data type K1 indicated by the rear stage type information of the rear stage storage unit 332 as the next data type because the authentication data is the third inspection value A3 + F1. S2068). Then, similarly to the main control board 310, the rear stage unit 202B detects reception of the detection target control command indicated by the detection target control command information from the main control board 310 (S2069), based on the switching information H described above. Switching from the numerical value F to the correction value C is set in the switching information H (S2070).

  Further, the peripheral portion 202A of the peripheral board 330 has the control command data 1001 and accompanying data received from the main control portion 201 when the post-authentication result information 1030 received from the post-stage portion 202B indicates that authentication has been established. When the predetermined processing corresponding to 1002 can be executed and the subsequent authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S2092). Thereafter, the same authentication process as described above is performed.

(Example of change procedure using expected value change data)
Next, the change procedure when the main control board 310 and the rear stage unit 202B according to the second embodiment change the inspection value and the expected value using the expected value change data is also the change procedure shown in FIG. Therefore, the description thereof is omitted.

  According to the pachinko gaming machine 100 described above, as in the first embodiment, the main control board 310 generates a predetermined inspection value among the first to third inspection values. Since it is not necessary to previously store the generated inspection value on the board 310, an increase in the amount of data stored in advance for authentication of the main control unit 201 in the pachinko gaming machine 100 can be suppressed. Further, even if the data of the main control board 310 is illegally analyzed, the generated inspection value is not stored, so that it is possible to contribute to the prevention of unauthorized analysis for the authentication of the main control board 310. Then, the main control unit 201 associates two types of authentication information with each of the first inspection value and the second inspection value of the three types of inspection values, and the first inspection value or the second inspection value. Since the authentication data is generated by the above, the authentication information 1020 having the authentication data is generated and transmitted to the subsequent stage 202B, the subsequent stage 202B associates the data type with the expected value. When the inspection value of the authentication information 1020 matches the expected value, the authentication of the main control unit 201 can be established and the data type of the authentication information 1020 to be received next time can be specified. An analyst can be prevented from using the authentication information 1020 illegally. Further, the main control unit 201 switches between a correction value and a coefficient value that are selectively used for the expected value change data according to the generation or transmission of the authentication information 1020 having the third inspection value, and the rear stage unit 202B Since the coefficient value F is switched in response to the reception of the authentication information 1020 having the third inspection value, the switching method and switching timing of the inspection value and the expected value can be made irregular. Analysis by a simple analyst can be made even more difficult. Then, the post-stage unit 202B can synchronize with the switching of the main control unit 201 by switching the correction value C and the coefficient value F in response to reception of the authentication information 1020 having the third inspection value. The inspection value and the expected value can be aligned and changed between the part 201 and the subsequent stage part 202B, and the analysis by an unauthorized analyst can be made even more difficult. Since only one type of authentication information 1020 has to be used, the addition to the conventional command system can be minimized and the processing of the main control unit 201 can be prevented from becoming complicated. Furthermore, since the latter part 202B can detect that the authentication information 1020 has been used illegally by the fraud analyst by the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. Further, since the rear stage unit 202B performs the authentication process for the main control unit 201 and transmits the subsequent stage authentication result to the peripheral unit 202A, the peripheral unit 202A only refers to the subsequent stage authentication result without performing the authentication process. Therefore, the processing load on the CPU 241 in the peripheral portion 202A can be reduced. Furthermore, since three types of inspection values can be stored in advance, it is not necessary to perform complicated calculations when generating the authentication information 1020, and an increase in processing load on the main control unit 201 can be prevented. In addition, the peripheral unit 202A transmits the authentication information 1020 from the main control unit 201 to the subsequent stage unit 202B as it is, so that the peripheral unit 202A can perform the predetermined process and the subsequent stage unit 202B can perform the authentication process. Therefore, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202A. Therefore, even if the data used for authentication and authentication is changed with one type of authentication information 1020, the authentication information 1020 and the unauthorized analysis of the change can be made difficult.

  In the pachinko gaming machine 100 described above, the main control board 310 generates at least one of the first to third inspection values based on the stored data in response to the activation of the pachinko gaming machine 100. Therefore, it is not necessary to store the generated inspection value in the data storage unit 311 in advance, and the authentication of the main control board 310 can be performed immediately after the pachinko gaming machine 100 is activated. This can contribute to the improvement of the authentication strength of 1020.

  In the pachinko gaming machine 100 described above, the main control unit 201 and the subsequent stage unit 202B store the inspection value and the expected value changed by the coefficient value expected value change data as the coefficient value previous inspection value and the coefficient value previous expected value. In addition, when the correction value was switched to the coefficient value again, the last changed inspection value and expected value were continuously changed. Therefore, analysis by an unauthorized analyst can be made even more difficult.

  In the pachinko gaming machine 100 described above, the main control unit 201 and the subsequent stage unit 202B associate the switching timing of the correction value C and the coefficient value F with the detection of a detection target control command determined in advance from a plurality of types of control commands. As a result, the interval of the switching timing can be made irregular and the correction value C and the coefficient value F can be switched between the main control unit 201 and the subsequent stage unit 202B. Analysis can be made even more difficult.

  In the pachinko gaming machine 100 described above, for example, the jackpot related command in the pachinko gaming machine 100 such as a jackpot reach command, a jackpot start command, a jackpot command, a jackpot end command, etc. is set as a detection target control command. Since an unauthorized jackpot related command is transmitted to the peripheral portion 202A because it is easily used illegally, the latter stage portion 202B detects it as a detection target control command and switches between the correction value C and the coefficient value F. The correction value C and the coefficient value F can be made inconsistent between the main control unit 201 and the subsequent stage unit 202B. Therefore, it is possible to contribute to improving the accuracy of detecting the occurrence of fraud.

  Further, in the above-described embodiment, the main control board 310, when detecting the detection target control command, when the number of regenerated authentication information having the third inspection value satisfies a predetermined switching condition, The rear stage unit 202B of the peripheral board 330 detects the reception of the detection target control command from the main control unit 201, and the number of times the authentication information having the third inspection value is received again satisfies the same switching condition as the main control unit. When it is satisfied, the correction value C and the coefficient value F can be switched. By adopting such a configuration, the timing for switching between the correction value C and the coefficient value F can be further complicated.

  Note that the method for controlling the main control unit and the peripheral units described in the present embodiment can be realized by executing a program prepared in advance on a computer such as a personal computer or a workstation. This program is recorded on a computer-readable recording medium such as a hard disk, CD-ROM, MO, DVD, and the like, and is executed by being read from the recording medium by the computer. The program may be an electric transmission medium that can be distributed via a network such as the Internet.

  As described above, the present invention is useful for a gaming machine in which fraud to the main control unit is concerned and a control board mounted on the gaming machine, and in particular, a pachinko gaming machine, a slot gaming machine, and a sparrow ball gaming machine. It can be applied to various other gaming machines.
