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.

  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 authentication is performed using one type of authentication information, and makes it difficult to perform illegal analysis of the authentication information. It is an object of the present invention to provide a gaming machine and a gaming machine authentication method that can be performed.

  According to the gaming machine authentication method of the present invention described in claim 11, when the main control unit randomly selects one inspection value from the two inspection values in the inspection value storage means, the type information is the authentication information. Authentication data having the selected inspection value is generated. In addition, 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. When a plurality of types of change target patterns are switched by a predetermined switching method, the main control unit changes the inspection value indicated by the switched change target pattern based on the generated expected value change data. Then, 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 intermediate 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. On the other hand, when the data type of the intermediate side type information indicates the authentication data, the intermediate unit compares the authentication data of the authentication information received from the main control unit with two types of expected values, and the comparison result The intermediate authentication result data indicating the authentication result of the main control unit based on the above can be generated and transmitted to the peripheral part. Then, when the authentication of the main control unit is established, the intermediate unit updates the intermediate type information by specifying the data type associated with the expected value that matches the authentication data of the authentication information as the next data type can do. In addition, the intermediate unit switches the same multiple types of change target patterns as the main control unit by a predetermined switching method of the main control unit, and when the data type of the intermediate side type information indicates expected value change data, The expected value that matches the inspection value indicated by the changed pattern to be changed can be changed based on the expected value changing data of the authentication information. On the other hand, the peripheral unit can perform a predetermined process in the gaming machine based on the control command received from the main control unit according to the intermediate authentication result data received from the intermediate unit.

  As described above, according to the present invention, two inspection values are associated with each of the two types of data of authentication information, and the main control unit uses the inspection value corresponding to the data type of authentication information to be generated next time. Since the authentication data is generated, the authentication information including the authentication data is generated and transmitted to the intermediate unit, the intermediate unit associates the data type with the expected value, so that the authentication information is obtained. When the test value and the expected value match, 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. Can be prevented. Since only one type of authentication information needs to be used, it is possible to minimize the addition to the conventional command system and prevent the processing on the main control side from becoming complicated. Further, when the expected value matches the inspection value included in the authentication information, the intermediate unit associates the expected value changing data of the data type with the expected value. Since it can be identified as data, it is possible to change the expected value with the expected value change data received from the main control unit and match the inspection value of the main control unit. It is possible to change the inspection value and the expected value in the same manner, and to make analysis by an unauthorized analyst difficult. Furthermore, two types of test values are prepared by preparing a plurality of change target patterns that define the target of change of expected value change data for each of two types of test values and expected values, and switching them using a predetermined switching method. Further, since the change to the expected value is complicated, it is possible to make it difficult for the fraud analyst to analyze the authentication information. Further, since the intermediate 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. And, since the intermediate unit performs the authentication process for the main control unit and transmits the intermediate authentication result to the peripheral unit, the peripheral unit only needs to refer to the intermediate authentication result without performing the authentication process. The processing load on the peripheral CPU can be reduced. Further, since the two inspection values can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in processing load on the main control unit can be prevented. Moreover, the intermediate unit transmits the control command from the main control side to the peripheral side as it is, so that the intermediate unit can perform the authentication process and the peripheral side can perform the predetermined process. A delay in processing can be prevented. Therefore, even if one type of authentication information is used, there is an effect that fraud analysis of the authentication information can be made difficult.

  In the above-described gaming machine, each of the two types of inspection values is associated with a different switching method on a one-to-one basis, and the switching method is switched according to the inspection value switching. Since it is possible to switch and a plurality of change target patterns can be switched by the switching method, the inspection value and the expected value can be changed to irregular values, and their analysis can be made more difficult. .

  In the gaming machine described above, since the change target patterns are switched using the change target pattern information indicating two or more types of change target patterns, it is possible to use more change target patterns than the number of inspection values and expected values. Therefore, the change to the inspection value and the expected value can be further complicated and the analysis can be made difficult.

  In the gaming machine described above, since the main control unit randomly generates the expected value change data, it is possible to randomly change both the inspection value of the main control unit and the expected value of the intermediate unit. Therefore, it is possible to make it difficult to analyze authentication information by an unauthorized analyst.

  In the gaming machine described above, since the expected value change data is a predetermined initial value and a correction value for changing the expected value, the main control unit and the intermediate unit have predetermined test values and expected values. Since it is only necessary to change the value with the expected value changing data, the changing process can be simplified.

  In the above-mentioned gaming machine, since the expected value change data is the coefficient value for changing the previously changed inspection value and expected value, the inspection value and expected value can be accumulated and changed. Analysis of values can be made even more difficult, and unauthorized use of inspection values and expected values can be prevented.

  In the gaming machine described above, an expected value having a value different from the inspection value of the main control unit is stored in advance in the intermediate unit, and the expected value change data for absorbing the difference between the inspection value and the expected value is main controlled. Since the intermediate part generates and sends it to the intermediate part, the expected value can be matched with the inspection value of the main control part by changing the expected value with the expected value change data by the intermediate part Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.

It can be set as various embodiments like the structure connected to this.

(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. The main control board 310 is a functional unit that transmits a control command for operating the peripheral board 330, and includes a data storage unit 311, a determination unit 312, an inspection value extraction unit 313, an authentication data generation unit 314, and an expected value change unit. The data generation unit 315, the main control side switching unit 316, the main control side changing unit 317, the authentication information generating unit 318, the main control side transmitting unit 319, and the updating unit 320 are configured. The main control board 310 is formed of a board different from the peripheral board 330 and is electrically connected so as to communicate with the peripheral board 330.

  The data storage unit 311 corresponds to the inspection value storage unit and the type information storage unit of the present invention, and includes two types of inspection values, authentication information, type information, authentication data, expected value change data, change target pattern information, etc. Various data are stored. 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. The data storage unit 311 has a storage area for storing authentication information transmitted to the peripheral unit. 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 peripheral board 330 (peripheral part) for authentication of the main control board 310 (main control part), and is generated by the CPU 211 described above. The expected value changing data is data for changing the two types of inspection values of the main control unit 201 and the two types of expected values of the intermediate unit 202A. To generate irregularly or based on an arbitrary counter, a predetermined value, or the like.

  The data storage unit 311 stores two different types of inspection values predetermined for the pachinko gaming machine 100 at the time of design, manufacture, and the like. Each of the two inspection values includes, for example, a checksum of two different predetermined areas in the ROM 212 of the main control unit 201, a predetermined unique value, an odd number and an even number, a magnitude relation value, and the like. Each of the two types of inspection values is arbitrarily used as authentication data, and has a one-to-one correspondence with the data type indicating which data the authentication information has between authentication data and expected value change data. It has been. Specifically, type data for indicating the data type is associated with each of the two types of inspection values.

  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 data storage unit 311 associates data indicating two types of switching methods (to be described later) for switching a plurality of types of change target patterns indicated by the stored change target pattern information with each of the above-described two inspection values. I remember it. If a plurality of switching methods are not associated with the inspection value, it is possible to use three or more switching methods, and an embodiment in which they are switched can be used.

  The determination unit 312 corresponds to a determination unit of the present invention, and randomly determines the data type of authentication information that the main control board 310 generates next time from two types of authentication data and expected value change data. The determination unit 312 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. Makes it difficult to analyze fraudulently.

  The inspection value extraction unit 313 corresponds to the inspection value extraction unit of the present invention, extracts the inspection value associated with the next data type determined by the determination unit 312 from the data storage unit (inspection value storage unit) 311, The extracted inspection value is stored in the RAM 213 or the like. Then, one inspection value extracted by the inspection value extraction unit 313 becomes an inspection value used as authentication data for the current authentication information.

  The authentication data generation unit 314 corresponds to the authentication data generation unit of the present invention, and is extracted by the test value extraction unit 313 when the type information stored in the data storage unit 311 indicates authentication data. Authentication data having an inspection value is generated, and the authentication data is stored in the data storage unit 311 or the like. Then, the authentication data generation unit 314 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 312 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 two types of test values that are randomly switched. In this embodiment, the case where the authentication data is the extracted inspection value will be described. Instead, for example, the extraction is performed by a predetermined calculation method between the main control unit 201 and the peripheral unit. It is also possible to use a value obtained by calculating the inspection value.

  The expected value change data generation unit 315 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 main control is performed. Expected value change data for changing each of the two types of inspection values of the substrate 310 and the two types of expected values of the intermediate portion 202A in the peripheral substrate 330 is generated, and the expected value change data is stored in the data storage unit 311 or the like. To do. The expected value change data generation unit 315 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 includes correction values, coefficient values, and the like, which will be described later.

  The main control side switching unit 316 corresponds to the main control side switching means of the present invention, and a plurality of types of change target patterns for defining change targets of expected value change data for two types of inspection values are set in a predetermined switching method. Switch with. The main control side switching unit 316 switches the change target pattern by a predetermined switching method at a predetermined switching timing. As an example of the switching timing, after generating the expected value changing data, at the time of generating the authentication data, and the like can be mentioned. As an example of the switching method, it is possible to synchronize with the switching of the inspection value and the expected value, or to use a switching table.

  The main control side changing unit 317 corresponds to the main control side changing unit of the present invention, and the inspection value of the data storage unit 311 (inspection value storage unit) indicated by the change target pattern switched by the main control side switching unit 316, The expected value changing data generating unit 315 changes the data based on the expected value changing data. The main control side changing unit 317 uses the change method and the expected value changing data that are determined in advance between the main control board 310 and the peripheral board 330, and the inspection to be changed among the two types of inspection values. Change the value. As the change method, for example, various calculation methods such as +, −, *, /, AND, OR, XOR, and a predetermined function can be used.

  The authentication information generation unit 318 corresponds to the authentication information generation unit of the present invention, and includes authentication data generated by the authentication data generation unit 314 or expected value change data generated by the expected value change data generation unit 315. Generate information. When the authentication information generation unit 318 of the present embodiment generates authentication information having either one of authentication data or expected value change data and an authentication command different from the control command of the pachinko gaming machine 100 Will be described. Alternatively, the authentication information may have a data structure further including other data.

  The main control side transmission unit 319 corresponds to the main control side transmission unit of the present invention, and each of the authentication information generated by the authentication information generation unit 318 and the control command data is individually provided at an intermediate portion of the peripheral board 330 at different timings. 202A. Then, the main control side transmission unit 319 of the present embodiment transmits control command data from the main control board 310 to the intermediate unit 202A of the peripheral board 330 as a control signal. For example, the transmission unit 316 transmits authentication information to the intermediate unit 202A as an authentication information signal that is a signal different from the control signal transmitted from the main control board 310 to the intermediate unit 202A. Thereby, in pachinko gaming machine 100, the control signal and the authentication information signal are differentiated.

  The update unit 320 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.

  When the pachinko gaming machine 100 of the present invention uses two kinds of inspection values for authentication of the main control board 310, the main control board 310 can change the inspection values with the expected value change data, so that the peripheral board The intermediate part 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. Moreover, since the value to be changed among the two types of inspection values can be defined by a plurality of types of change target patterns, and these change target patterns can be switched and changed, analysis of the changed inspection values and expected values can be performed. Can be 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 202B will be described. As shown in FIG. 3, the peripheral board 330 includes an intermediate part 202A and a peripheral part (effect control part) 202B. The peripheral board 330 is configured such that the intermediate portion 202A and the peripheral portion 202B can communicate with each other. In the present embodiment, the peripheral board 330 having the intermediate section 202A and the effect control section 202B will be described. Alternatively, a peripheral board having the intermediate section 202A and the prize ball control section 203 may be used. it can.

  Next, the intermediate unit 202A includes an intermediate receiving unit 331, an intermediate storage unit 332, an intermediate authentication result data generating unit 333, an intermediate transmitting unit 334, an intermediate switching unit 335, an intermediate changing unit 336, and an identifying unit 337. Have.

  The intermediate receiving unit 331 corresponds to the intermediate receiving unit of the present invention, and receives each of the authentication information and control command data transmitted by the main control board 310. The intermediate receiving unit 331 of the present embodiment receives the authentication information from the main control board 310 by receiving an authentication information signal corresponding to the authentication information, for example. Further, when receiving a control signal having control command data separately from the authentication information signal from the main control unit 201, the intermediate receiving unit 331 transmits the control signal as it is from the intermediate transmitting unit 335 described later to the peripheral unit 202B. .

  The intermediate storage unit 332 corresponds to the expected value storage unit and the intermediate type information storage unit of the present invention. The intermediate storage unit 332 has two expectations that match the two inspection values to be received from the main control board 310 described above, that is, the two inspection values stored in the data storage unit 311 of the main control board 310. The value is memorized. Thereby, if the expected value matches the authentication data set in the authentication information, the intermediate portion 202A of the peripheral board 330 can determine that the authentication data is a normal inspection value. If the authentication data does not match the expected value, it can be determined that the authentication data is not an inspection value. In this embodiment, since the expected value can be changed by the above-described expected value changing data, the expected value stored in advance is different from the inspection value of the main control board 310, that is, coincides with it. There can be no value.

  The intermediate storage unit 332 stores each of the plurality of expected values described above in a one-to-one correspondence with each of the two types of authentication information described above. For example, the intermediate-side storage unit 332 can identify the data type from the expected value by storing type data indicating two types of data in association with the expected value.

  The intermediate storage unit 332 stores intermediate type information indicating the data type of the current authentication information. The intermediate 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 when no fraud has occurred. Therefore, the intermediate unit 202A can grasp the data type of the received authentication information in advance by referring to the intermediate type information before receiving the authentication information from the main control board 310.

  The intermediate storage unit 332 stores in advance the change target pattern information that is the same as that of the main control board 310 described above. Then, the intermediate storage unit 332 associates each of the two expected values described above with the same two types of switching methods as the main control board 310 for switching the change target pattern information on a one-to-one basis. ing. As a result, the peripheral board 330 can specify the same switching method as the main control board 310 from the expected value that matches the inspection value. Therefore, unless the unauthorized authentication information is received, the peripheral board 330 can communicate with the main control board 310. The change target pattern does not shift.

  The intermediate authentication result data generation unit 333 corresponds to the intermediate authentication result data generation means of the present invention, and when the data type of the intermediate side type information indicates the authentication data, the inspection value that is the authentication data Is compared with the expected value stored in the intermediate storage unit 332, and intermediate authentication result data indicating the authentication result of the main control board 310 based on the comparison result is generated. That is, the intermediate authentication result data indicates an authentication result indicating whether or not the intermediate unit 202A has authenticated the main control board 310 (main control unit 201). Then, as an example of the authentication method of the intermediate authentication result data generation unit 333, it is determined whether the inspection value and the expected value match, and if they match, the authentication of the main control board 310 is established, If they do not match, authentication is not established.

  The intermediate transmission unit 334 corresponds to the intermediate transmission unit of the present invention, and transmits the intermediate authentication result data generated by the intermediate authentication result data generation unit 333 to the peripheral unit 202B. Then, the intermediate transmission unit 334 transmits the intermediate authentication result data generated by the intermediate authentication result data generation unit 333 to the peripheral unit 202B as an intermediate authentication result signal. Further, the intermediate transmission unit 334 transmits the control signal received from the main control board 310 to the peripheral unit 202B as it is. That is, the main control unit 201 transmits a control signal (control command) to the peripheral unit 202B via the intermediate unit 202A.

  The intermediate-side switching unit 335 corresponds to the intermediate-side switching unit of the present invention, and switches a plurality of types of change target patterns that are the same as the main control unit 201 using the predetermined switching method of the main control-side switching unit 316 described above. The intermediate side switching unit 335 switches the change target pattern by a predetermined switching method at a predetermined switching timing. Examples of the switching timing include when the expected value change data is received, when authentication of the authentication data is established, and the like. As an example of the switching method, a method of synchronizing with switching of the inspection value and the expected value, a method using a common switching table, and the like can be cited.

  The intermediate-side changing unit 336 corresponds to the intermediate-side changing unit of the present invention, and when the data type of the intermediate-side type information indicates the expected value changing data, the change target switched by the intermediate-side switching unit 335 The expected value of the intermediate storage unit 332 that matches the inspection value indicated by the pattern is changed based on the expected value changing data of the received authentication information. The intermediate side changing unit 336 changes the two types of expected values using the same changing method and expected value changing data as the main control side changing unit 317 of the main control board 310. Then, the intermediate side changing unit 336 receives the incorrect authentication information when the data type of the intermediate side type information indicates the expected value changing data, and then determines the two types of expected values with the incorrect data. Since the change is made, the value is changed to a value different from the inspection value of the main control board 310, and authentication of the subsequent authentication information is not established.

  The specifying unit 337 corresponds to the specifying unit of the present invention. When authentication of the main control board 310 is established by the intermediate authentication result data generating unit 333, the specifying unit 337 associates with the expected value that matches the inspection value constituting the authentication data.

The peripheral side reception unit 351 of the present embodiment receives the intermediate authentication result data from the intermediate unit 202A, for example, by receiving an intermediate authentication result signal to which the intermediate authentication result data is added. Then, the peripheral side receiving unit 351 receives a control command from the main control board 310 by receiving a control signal from the intermediate unit 202A.

  The processing unit 352 corresponds to the processing means of the present invention, and performs predetermined processing in the pachinko gaming machine 100 according to the control command received from the main control board 310 according to the intermediate authentication result data received from the intermediate unit 202A. Do. When the intermediate authentication result data indicates that authentication has been established, the processing unit 352 performs the predetermined processing corresponding to the control command indicated by the control signal received from the intermediate unit 202A, and indicates that authentication has not been established. Will alert you. The predetermined process is a process corresponding to a control command from the main control unit 201 in the pachinko gaming machine 100. For example, a loss process, a jackpot reach process, a jackpot start process, a jackpot round process, a jackpot end process, etc. Can be mentioned.

  In the present embodiment, a description will be given of a configuration in which data communicated between the intermediate unit 202A and the peripheral unit 202B is transmitted without encryption. However, as described in the main control board 310 and the intermediate unit 202A described above. In addition, data may be encrypted and transmitted between the intermediate unit 202A and the peripheral 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 202B every time a game ball wins the start winning opening 105, and the effect control unit 202B 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 202B when the occurrence of the jackpot is determined, and the effect control unit 202B aligns with a predetermined symbol and stops the variable display, Control is performed to open the special winning opening 109. The effect control unit 202B performs various effect displays on the symbol display unit 104 in addition to the symbol variation display 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, control processing of the effect control unit 202B 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 202B. 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 202B and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this processing, the effect control unit 202B 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 S410. 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 202B, 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 202B. 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, when 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 202B, and proceeds to the process of step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202B. Subsequently, in step S417, the main control unit 201 sequentially transmits commands corresponding to each of the rounds in the jackpot to the effect control unit 202B. To do. Then, when transmission of the jackpot command for all the rounds is completed, the main control unit 201 transmits a jackpot end command to the effect control unit 202B in step S418, and the process proceeds to 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 a loss reach command (symbol variation command) to the effect control unit 202B. 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 202B, 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 202B, and ends the process according to this flowchart.

  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 202B 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 (peripheral unit) 202B will be described with reference to the flowchart shown in FIG. The effect control unit 202B 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 202B waits for the symbol variation command to be received by repeating this determination process. On the other hand, if it is determined that the symbol change command has been received (S701: Yes), the effect control unit 202B acquires a random effect selection random number in step S702, and in step S703, the variable effect is selected based on the acquired random number. The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202B transmits an effect start command for each variable effect to the lamp control unit 251 and the audio control unit 252, and the process proceeds to step S705.

  In step S705, the effect control unit 202B determines whether the effect time has elapsed. When the effect control unit 202B determines that the effect time has elapsed (S705: Yes), the effect control unit 202B 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 202B 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 202B 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 determining that the symbol stop command has been received (S706: Yes), the effect control unit 202B transmits the effect stop command to the lamp control unit 251 and the voice control unit 252 in step S707, and according to this flowchart. The process ends.

  Next, the big hitting process by the effect control unit 202B will be described with reference to the flowchart shown in FIG. The effect control unit 202B determines whether or not a jackpot start command (see step S416 in FIG. 5) is 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 202B 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 202B 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 202B determines whether or not 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 202B repeats this determination process to wait for the jackpot command to be received. On the other hand, when it is determined that the jackpot command has been received (S803: Yes), the effect control unit 202B 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 202B determines whether or not 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 202B waits for the reception of the jackpot end command by repeating this determination process. On the other hand, if it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202B 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 an effect start command is received from the effect control unit 202B (during symbol variation) will be described. Then, the lamp control unit 251 determines whether or not an effect start command is received from the effect control unit 202B in step S901 illustrated in FIG. 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 202B. 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.

(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 the present embodiment, description will be made on the assumption that the main control unit 201 outputs an authentication information signal to the intermediate unit 202A, thereby transmitting the authentication information from the main control unit 201 to the intermediate unit 202A.

  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. As an example of the identification data, there is one type of authentication command different from the control command of the control command data 1001. For example, a value such as hexadecimal 0xA0 is set. Accordingly, the intermediate unit 202A 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.

  In the data part 1022, either one of the authentication data having one of the above-described two types of 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 intermediate authentication result signal shown in FIG. 11 includes intermediate authentication result information 1030 indicating an authentication result obtained by authenticating the main control unit 201 using the plurality of types of authentication information 1020 described above by the intermediate unit 202A. To send to. The intermediate authentication result information 1030 includes an identification unit 1031 and a result unit 1032. The identification unit 1031 is set with authentication result identification data capable of identifying the intermediate authentication result information 1030. As the 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.

(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 authentication data K1, the data portion 1022 of the authentication information 1020 has an authentication having one of two types of inspection values A1 and A2 (where A1 ≠ A2). Data 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 expected value. As the correction value C, for example, the correction value generated once at the start of the pachinko gaming machine 100 or at the first authentication may be used repeatedly, or the correction value C may be generated a plurality of times to change the correction value C irregularly. However, in the present embodiment, a case where the correction value Cn (n is an integer) is irregularly changed every time the expected value change 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 two types of inspection values A1, A2, expected values B1, B2, and data types K1, K2 of authentication information 1020 will be described.

  First, in the pachinko gaming machine 100, as shown in FIG. 13, when two types of inspection values A1 and A2 for the main control board 310 are set, expected values B1 and B2 corresponding to the two types of inspection values A1 and A2 are set. B2 is set for the peripheral substrate 330. Then, the data types K1 and K2 of the authentication information 1020 are assigned to the inspection values A1 and A2 and the expected values B1 and B2, respectively. The main control board 310 stores the inspection values A1 and A2 in association with the data types K1 and K2 of the authentication information 1020. The peripheral board 330 stores the expected values B1 and B2 in association with the data types K1 and K2 of the authentication information 1020. Since the inspection values A1 and A2 and the expected values B1 and B2 are changed by the expected value changing data, for example, the association with the data types K1 and K2 is updated every time it is changed. Different embodiments may be made, such as associating each of the values with an initial value.

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

  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 intermediate portion 202A of the peripheral board 330, and changes the inspection value A1, which is an initial value, by the correction value C1. The inspection value A1 + C1 and the inspection value A2, which is the initial value, are changed by the correction value C1 to obtain the inspection value A2 + C1. On the other hand, when the intermediate portion 202A of the peripheral board 330 receives the correction value C1 from the main control board 310, the expected value B1 that is the initial value is changed by the correction value C1, and the expected value B1 + C1 and the expected value B2 that is the initial value are obtained. The value is changed by the correction value C1 to obtain an expected value B2 + C1. Therefore, since the matched inspection value and the expected value are changed with the same correction value, the inspection value A1 + C1, inspection value A2 + C1 of the main control board 310 and the expected value B1 + C1, expected value B2 + C1 of the intermediate portion 202A are the same. In this case, since the intermediate unit 202A can determine that the inspection values A1 + C1 and A2 + C1 of the authentication information received from the main control board 310 are valid, the 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 intermediate portion 202A of the peripheral board 330 and the inspection value A1 that is an initial value. The inspection value A1 + C2 is changed by the correction value C2, and the inspection value A2 which is the initial value is changed by the correction value C2 to be the inspection value A2 + C2. On the other hand, when the intermediate portion 202A of the peripheral board 330 receives the correction value C2 from the main control board 310, the expected value B1 that is the initial value is changed by the correction value C2, and the expected value B1 + C1 and the expected value B2 that is the initial value are obtained. The value is changed by the correction value C2 to obtain an expected value B2 + C2. Therefore, since the matched inspection value and the expected value are changed with the same correction value, the inspection value A1 + C2, the inspection value A2 + C2 of the main control board 310 and the expected value B1 + C2, the expected value B2 + C2 of the intermediate portion 202A match. In this case, since the intermediate unit 202A can determine that the inspection values A1 + C2 and A2 + C2 of the authentication information received from the main control board 310 are valid, the authentication of the main control board 310 can be established. The same change is made for the third and subsequent changes.

  Next, when the initial inspection value A1 in the main control board 310 and the initial expected value B0 in the intermediate portion 202A of the peripheral board 330 do not match (A1 ≠ B0), they are changed by the correction value Cn. A modification example will be described. In order to simplify the description, the description is limited to the case where only the inspection value A1 and the expected values B0 and B1 are changed.

  In the first change, when the main control board 310 generates a difference correction value C0 (= A1-B0) between the inspection value A1 and the expected value B0 stored in advance in the data storage unit 311 or the like, the difference correction value C0 is transmitted to the intermediate portion 202A of the peripheral board 330. On the other hand, when the intermediate portion 202A of the peripheral board 330 receives the difference correction value C0, the expected value B0 that is the initial value is changed to the expected value B1 (= B0 + C0) by the difference correction value C0. As a result, the expected value B1 is changed to a value that matches the 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 intermediate portion 202A of the peripheral board 330, and changes the initial inspection value A1 with the correction value C1. The inspection value is A1 + C1. On the other hand, when the intermediate portion 202A of the peripheral board 330 receives the correction value C1 from the main control board 310, the expected value B1 changed last time is changed to the expected value B1 + C1 by the correction value C1. Therefore, since the matched inspection value A1 and the expected value B1 are changed with the same correction value C1, when the inspection value A1 + C1 of the main control board 310 matches the expected value B1 + C1 of the intermediate portion 202A, the intermediate portion Since 202A can determine that the inspection value A1 + C1 of the authentication information received from the main control board 310 is authentic, 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.

  Next, when the initial inspection value A1 in the main control board 310 and the initial expected value B0 in the intermediate portion 202A of the peripheral board 330 do not match (A1 ≠ B0), they are changed by the correction value Cn. Another modification will be described. In order to simplify the description, the description is limited to the case where only the inspection value A and the expected value B are changed.

  In the first change, the main control board 310 generates the difference correction value C0 (= A0−B0) between the inspection value A1 and the expected value B0 stored in advance in the data storage unit 311 or the like. C0 is stored in the data storage unit 311 or the like. Then, for example, when the main control board 310 creates the current correction value C1 by adding the difference correction value C0 and the current value, the main control board 310 transmits the correction value C1 to the intermediate portion 202A of the peripheral board 330 and the initial value. The inspection value A1, which is a value, is changed by the correction value C1 to obtain an inspection value A1 + C1. On the other hand, when receiving the correction value C1 from the main control board 310, the intermediate portion 202A of the peripheral board 330 corrects the expected value B0, which is the initial value, with the correction value C1 to obtain the expected value B0 + C1. As a result, the main control board 310 generates a correction value C1 that absorbs the difference between the inspection value A1 and the expected value B0 and transmits it to the intermediate unit 202A. The intermediate unit 202A performs correction and authentication using the expected value B0 as it is. It will be better.

  Next, each of the previous inspection values A1 (n−1) and A2 (n−1) and the expected values B1 (n−1) and B2 (n−1) are changed using the coefficient value Fn described above. A modification example will be described. In the pachinko gaming machine 100, it is assumed that the inspection values A1, A2 correspond to the expected values B1, B2 (A1n = B1n, A2n = B2n), n is an integer, and the change method is “*”.

  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 intermediate portion 202A of the peripheral board 330, and changes the inspection value A11 that is the initial value by the coefficient value F1. The inspection value A12 and the inspection value A21 which is the initial value are changed to the inspection value A22 by the coefficient value F1. On the other hand, when the intermediate portion 202A of the peripheral board 330 receives the coefficient value F1 from the main control board 310, the expected value B11 that is the initial value is changed by the coefficient value F1, and the expected value B12 and the expected value B21 that is the initial value are set. The coefficient value F1 is changed to an expected value B22. Accordingly, since the matched inspection value and the expected value are changed with the same coefficient value, the inspection value A12 and inspection value A22 of the main control board 310 and the expected value B12 and expectation value B22 of the intermediate portion 202A match. In this case, since the intermediate unit 202A can determine that the inspection values A12 and A22 of the authentication information received from the main control board 310 are valid, 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 intermediate portion 202A of the peripheral board 330, and the inspection values A12 and A22 changed last time. The inspection values A13 and A23 are changed by the coefficient value F2. On the other hand, when the intermediate portion 202A of the peripheral board 330 receives the coefficient value F2 from the main control board 310, the previously changed expected values B12 and B22 are changed to the expected values B13 and B23 by the coefficient value F2. Therefore, since the previously changed inspection value and the expected value are changed with the same coefficient value, the inspection value A13 and inspection value A23 of the main control board 310 and the expected values B13 and B23 of the intermediate portion 202A match. Furthermore, since the intermediate unit 202A can determine that the inspection values A13 and A23 of the authentication information received from the main control board 310 are authentic, 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 intermediate portion 202A.

  Next, an example of a change target pattern and a switching method used for switching will be described below. Each of the plurality of types of change target patterns indicates a pattern that defines a value to be changed among the two types of inspection values and expected values. In the present embodiment, change target pattern information indicating a plurality of types of change target patterns determined in advance is stored in both the main control board 310 and the intermediate portion 202A of the peripheral board 330, and the change target pattern information indicates the change target pattern information. A case where a plurality of types of change target patterns are switched synchronously on both sides will be described.

  The change target pattern information 1040 shown in FIG. 14 has a data structure indicating four types of change target patterns P1 to P4 for the inspection values A1 and A2 and the expected values B1 and B2. In the change target pattern P1, the main control unit 201 side defines the inspection value A1 and the intermediate unit 202A side defines the expected value B1 as the change target. In the change target pattern P2, the main control unit 201 side defines the inspection value A2, and the intermediate unit 202A side defines the expected value B2. In the change target pattern P3, the main control unit 201 side defines the inspection value A1 and the inspection value A2, and the intermediate unit 202A side defines the expected value B1 and the expected value B2. The change target pattern P4 indicates that there is no change on both the main control unit 201 side and the peripheral side.

  In the present embodiment, the case where the change target pattern P4 is used will be described. Instead, the change target pattern P4 without change is deleted, and the change target pattern information 1040 is configured only by the change target patterns P1 to P3. May be. In addition, for example, the change target pattern information 1040 may be configured to have data such as the number of times that the change target pattern is valid, the change timing using the change target pattern, and the like.

  Next, an example of a switching method of the change target patterns P1 to P4 will be described with reference to the drawing of FIG. In the switching method of the present embodiment, the number of switching from the currently used change target pattern is “1 advance” or “2 advance” with respect to the order of the change target patterns P1 to P4. In addition, various embodiments such as a combination of “1 advance” and “2 return” as a switching method, and a combination of “1 return” and “2 advance” can be used.

  As shown in FIG. 15, each of the switching methods of “1 advance” and “2 advance” is associated with each of the inspection values A1 and A2 on the main control board 310 in a one-to-one correspondence. The intermediate portion 202A has a one-to-one correspondence with each of the expected values B1 and B2. Then, when the inspection value A1 is extracted (selected) when the change target pattern P1 is used, the main control board 310 switches to the change target pattern P2 because the switching method becomes “1 advance”. In addition, when the change target pattern 1 is used and the authentication of the expected value B2 is established, the intermediate unit 202A of the peripheral board 330 switches to the change target pattern P3 because the switching method is “2 advance”. Therefore, in the pachinko gaming machine 100, if an irregularity occurs between the main control board 310 and the intermediate portion 202A of the peripheral board 330, the switching method switching does not match, and thereafter, the authentication by the inspection value is not established, The intermediate portion 202A of the peripheral board 330 can detect the occurrence of the fraud.

  In the present embodiment, the case where the change target pattern is switched using the change target pattern information has been described. Instead of this, for example, each of the two types of change target patterns P1 and P2 described above is subjected to two types of inspection. It is also possible to adopt an embodiment in which the values are associated with the values A1 and A2 and the inspection values A1 and A2 are switched to the change target pattern P associated with the inspection value A used for generating the authentication data. Specifically, when the inspection value A1 is used for generating the authentication data, the pattern is switched to the change target pattern P1 associated with the inspection value A1. Note that the switching method in this case is the extraction result or selection result of the inspection values A1 and A2 used for the authentication data. Moreover, it can also be set as various different embodiments also about those matching so that change object pattern P1, P2 and test value A2, A1 may be matched on a one-to-one basis. Furthermore, it can also be set as the embodiment which switches a change object pattern using the change object pattern information mentioned above and a predetermined random number table.

  Furthermore, without using the above-described change target pattern information, processing, algorithms, and the like for changing values corresponding to each of a plurality of types of change target patterns are stored in the main control board 310 and the peripheral board 330 as programs. In addition, an embodiment in which a program corresponding to the change target pattern is executed may be used.

(Processing for sending and receiving authentication information signals)
Hereinafter, a communication example of the authentication information signal performed between the main control unit 201 and the intermediate unit 202A 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 a 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. 16, and determines in step S1201 whether or not it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1201: No), the main control unit 201 proceeds to the process of step S1214. 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 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 S1203. 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 S1203, the main control unit 201 determines whether or not the current data type is authentication data. If the data type is not the authentication data, that is, the expected value change data (S1203: No), the main control unit 201 proceeds to the process of step S1204. In step S1204, the main control unit 201 randomly generates expected value change data for changing the inspection value and the expected value using a predetermined generation method, and generates the generated expected value change data. It memorize | stores in the data memory | storage part 311 grade | etc., And progresses to the process of step S1205 after that. An example of a method for generating expected value change data is to generate the expected value change data by using the generation method using a random number or a pattern table.

  In step S1205, the main control unit 201 uses the change method described above with the expected value change data stored in the data storage unit 311 for the test value indicated by the current change target pattern among the two types of test values. Then, the process proceeds to step S1206. Note that the test value can be changed at various timings such as when the expected value change data is generated and when the authentication data is generated. In step S1206, the main control unit 201 determines a data type K1 that is predetermined for generating expected value change data as the next data type and stores it in the RAM 213 or the like, and then performs the process in step S1211. move on. The predetermined data type is predetermined between the main control board 310 and the intermediate portion 202A of the peripheral board 330.

  On the other hand, when the main control unit 201 determines in step S1203 that the data type is authentication data (S1203: Yes), in step S1207, the authentication information to be generated next time from the authentication data and the expected value change data. The data type is randomly determined and stored in the RAM 213 and the like, and then the process proceeds to step S1208.

  In step S1208, the main control unit 201 extracts inspection values corresponding to the next data type determined in step S1207 from the two types of inspection values and stores them in the RAM 213 and the like, and then proceeds to the processing of step S1209. In step S1209, the main control unit 201 switches the change target pattern to the plurality of types of change target patterns indicated by the change target pattern information using the switching method associated with the extracted inspection value, and the changed change. The target pattern is stored in the RAM 213 or the like, and then the process proceeds to step S1210. When a known pointer is used as a change target pattern switching method, the change target pattern indicated by the current pointer is stored in the RAM 213 or the like, and the pointer is moved and switched based on the switching method.

  In step S1210, the main control unit 201 generates authentication data having the extracted inspection value and stores it in the RAM 213 or the like, and then proceeds to the processing of step S1211. As a result, authentication data having one of two types of inspection values is created.

  In step S1211, 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 S1212.

  In step S1212, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the intermediate unit 202A, and in step S1213, 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 319 to the intermediate unit 202A of the peripheral board 310, and then the process proceeds to step S1214. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the processing in step S1212 is deleted, and the authentication information 1020 is transmitted to the intermediate unit 202A as it is. In step S1214, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1206 or step S1207, and then proceeds to the processing in step S1215.

  In step S1215, 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 (S1215: No), the main control unit 201 returns to the process of 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 (S1215: Yes), the process according to this flowchart ends.

  Subsequently, a procedure of authentication information reception processing by the CPU 231 (second computer) of the intermediate unit 202A will be described with reference to a flowchart of FIG.

  When the intermediate unit 202A executes the authentication-side process shown in FIG. 17, in step S1301, the intermediate unit 202A determines whether or not the authentication information (authentication information signal) 1020 has been received from the main control unit 201 by the intermediate-side receiving unit 331. If the intermediate unit 202A determines that the authentication information 1020 has not been received (S1301: No), the process proceeds to step S1312. On the other hand, if the intermediate unit 202A determines that the authentication information 1020 has been received (S1301: Yes), the intermediate authentication unit 20A 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 S1302. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the decryption process in step S1301 is deleted.

  In step S1302, the intermediate unit 202A determines whether the intermediate type information in the intermediate storage unit 322 indicates authentication data. If it is determined that the intermediate unit 202A indicates authentication data (S1302: Yes), in step S1303, the authentication unit 10A extracts the authentication data from the data unit 1022 of the authentication information 1020 and stores it in the intermediate storage unit 332 or the like. Thereafter, the process proceeds to step S1304.

  In step S1304, intermediate unit 202A compares the authentication data with the two types of expected values stored in intermediate storage unit 322, and whether the expected value data matches any expected value. Determine whether. If it is determined that the intermediate unit 202A matches the expected value (S1304: Yes), in step S1305, intermediate authentication result data indicating that authentication has been established is generated and stored in the RAM 233 or the like. In step S1306, the intermediate unit 202A The data type associated with the expected value that matches the data is specified, and the specified data type is set as the next data type in the intermediate side type information of the intermediate storage unit 332, and then the process proceeds to step S1307.

  In step S1307, the intermediate unit 202A specifies a switching method corresponding to the test value for which authentication has been established, that is, a switching method associated with an expected value that matches the test value, and the change target pattern information is determined using the switching method. Are switched, the changed pattern to be changed is stored in the RAM 243 and the like, and then the process proceeds to step S1309. Note that the switching method of the intermediate unit 202A is the same switching method as the main control unit 201.

  On the other hand, if the intermediate unit 202A determines in step S1304 that it does not match the expected value (S1304: No), in step S1308, the intermediate unit 202A generates intermediate authentication result data indicating failure of authentication and stores it in the RAM 233, etc. The process proceeds to step S1309.

  In step S1309, the intermediate unit 202A sets the generated intermediate authentication result data in the result unit 1032 to generate intermediate authentication result information 1030, and generates an intermediate authentication result signal with the intermediate authentication result information 1030 added. The transmission is performed from the intermediate transmission unit 334 to the peripheral unit 202B, and then the process proceeds to step S1311.

  On the other hand, if the intermediate unit 202A determines in step S1302 that the intermediate type information does not indicate authentication data (S1302: No), in step S1310, the intermediate value 202A receives the expected value change data from the data unit 1022 of the authentication information 1020. Extracted and stored in the intermediate storage unit 332 or the like, and in step S1311, the inspection value of the intermediate storage unit 332 indicated by the current change target pattern is changed by the above-described change method using the extracted expected value change data. Then, the process proceeds to step S1312. Note that the expected value can be changed at various timings such as when the expected value changing data is received and before authentication by the authentication data.

  In step S1312, the intermediate unit 202A determines whether or not the pachinko gaming machine 100 is powered off. If the intermediate unit 202A determines that the power is not turned off (S1312: No), the intermediate unit 202A returns to the process of step S1301 and repeats a series of processes. On the other hand, when it is determined that the power is turned off (S1312: Yes), the intermediate unit 202A ends the process according to this flowchart.

  Next, the procedure of receiving various control signals and intermediate authentication result signals by the CPU 241 (third computer) of the peripheral unit 202B will be described with reference to the flowchart of FIG.

  In step S1401, the peripheral unit 202B determines whether or not the control signal 1010 has been received from the intermediate unit 202A. If it is determined that the control signal 1010 has been received (S1401: Yes), the peripheral unit 202B performs predetermined processing based on the control command data 1001 and the accompanying data 1002 included in the received control signal 1010 in step S1402. Thereafter, the process proceeds to step S1405.

  On the other hand, when it is determined that the peripheral unit 202B has not received the control signal 1010 (S1401: No), in step S1403, based on whether or not the received signal includes the identification unit 1031, the intermediate unit It is determined whether an intermediate authentication result signal is received from 202A. If the peripheral unit 202B determines that the intermediate authentication result signal has not been received (S1403: No), the process proceeds to step S1405. On the other hand, if it is determined that the intermediate authentication result signal is received (S1403: Yes), the peripheral unit 202B proceeds to the process of step S1404.

  In step S1404, the peripheral unit 202B refers to the result unit 1032 of the received intermediate authentication result signal, and determines whether or not the intermediate authentication result signal indicates that authentication has been established. If the peripheral unit 202B determines that the intermediate authentication result indicates that authentication has been established (S1404: Yes), the peripheral unit 202B stores the authentication result in the RAM 243 or the like, and then proceeds to the processing of step S1405.

  In step S1405, the peripheral unit 202B determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power is not turned off (S1405: No), the peripheral unit 202B returns to the process of step S1401 and repeats a series of processes. On the other hand, when it is determined that the power is turned off (S1405: Yes), the peripheral unit 202B ends the process according to this flowchart.

  On the other hand, if it is determined in step S1404 that the intermediate authentication result does not indicate that the authentication is successful (S1404: No), the peripheral unit 202B outputs a notification signal from, for example, the speaker 262 (see FIG. 2) or the like in step S1406. Then, the process according to this flowchart is terminated. As for the processing of the peripheral portion 202B when the intermediate authentication result does not indicate that authentication has been established, that is, when authentication has not been established, the processing of the peripheral portion 202B is continued only by outputting a notification signal. Also good.

(Example of authentication processing procedure using authentication information)
Next, an example of a procedure for performing authentication of the main control board 310 by switching the data types K1 and K2 shown in FIG. 12 will be described with reference to the drawings of FIGS. In the present embodiment, only the case where the change method is “+” will be described in order to simplify the description.

  In FIG. 19, the main control board 310 that is the person to be authenticated sets a predetermined data type K1 for this time (S1501). 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 (S1502), and as shown in FIG. 13, the data type K2 The authentication data of the inspection value A2 associated with is generated (S1503). Then, the main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the intermediate section 202A of the peripheral board 330 (S1504). Then, the main control board 310 indicates the change target pattern P1 as an initial setting with respect to the change target pattern information 1040 shown in FIG. 14, and the inspection value A2 of the acceptance data is as shown in FIG. Since the switching method “2 advance” is associated, the change target pattern P1 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1505).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A2) from the main control board 310 (S1551), the initial intermediate type information indicates the authentication data, so the authentication information 1020 ( A2) It is determined whether or not the authentication data in the data section 1022 and the two types of expected values stored in the intermediate storage section 332 match, and the authentication result of the main control board 310 based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the above is generated and stored in the intermediate storage unit 332 (S1552). Then, the intermediate unit 202A transmits an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto to the peripheral unit 202B of the peripheral board 330 (S1553). Moreover, since the authentication data is the inspection value A2 when the authentication is established, the intermediate unit 202A matches the expected value B2 of the intermediate storage unit 322. Therefore, the data type K2 associated with the inspection value B2 Is identified as the next data type, and the intermediate type information in the intermediate storage unit 322 is updated to indicate this data type (S1554). Similarly to the main control board 310, the intermediate unit 202A indicates the change target pattern P1 as an initial setting for the change target pattern information 1040, and sets the inspection value A2 of the authentication information 1020 for which the authentication has been established. Since the switching method “advance 2” is associated, the change target pattern P1 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1555). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P3.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1581).

  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 (S1506). 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 (S1507). The main control board 310 randomly generates the expected value changing data C1 for changing the inspection value and the expected value by a predetermined generation method (S1508), and the authentication information 1020 having the expected value changing data. (C1) is generated, and the authentication information 1020 (C1) is transmitted to the intermediate portion 202A of the peripheral board 330 (S1509). Then, as shown in FIG. 14, the main control board 310 changes the inspection values A1 and A2 indicated by the change target pattern P3 to the inspection value (A1 + C1) and the inspection value (A2 + C1) by the change method described above (S1510).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (C1) from the main control board 310 (S1556), the intermediate type information in the intermediate storage section 322 indicates expected value change data. From the expected value change data C1 of the data portion 1022 of the authentication information 1020 (C1), the expected values B1 and B2 defined by the change target pattern P3 shown in FIG. The value is changed to (B2 + C1) (S1557). As a result, the inspection value (A1 + C1) and inspection value (A2 + C1) of the main control board 310 and the expected value (B1 + C1) and the expected value (B2 + C1) of the intermediate portion 202A of the peripheral board 330 are maintained. become. Then, the intermediate unit 202A specifies a data type K1 predetermined for generating expected value change data as the next data type, and the intermediate type information of the intermediate storage unit 322 indicates this data type. Is updated (S1558).

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

  Subsequently, in FIG. 20, 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 (S1511). 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 (S1512). The main control board 310 generates authentication data for the inspection value (A1 + C1) associated with the data type K1 (S1513). 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 intermediate portion 202A of the peripheral board 330 (S1514). The main control board 310 indicates the change target pattern 3 with respect to the change target pattern information 1040, and the current inspection value (A1 + C1) of the authentication data is associated with the switching method “advance one”. Therefore, the change target pattern P3 is switched to the change target pattern P4, and the change target pattern P4 is stored in the RAM 213 or the like (S1515).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A1 + C1) from the main control board 310 (S1559), the intermediate type information in the intermediate storage section 322 indicates authentication data. It is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C1) matches the two types of expected values stored in the intermediate storage unit 332, and the main control board based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the authentication result 310 is generated and stored in the intermediate storage unit 332 (S1560). Then, the intermediate unit 202A transmits an intermediate authentication result signal added with the intermediate authentication result information 1030 to the peripheral unit 202B of the peripheral board 330 (S1561). Further, when authentication is established, the intermediate unit 202A corresponds to the expected value (B1 + C1) because the authentication data is the inspection value (A1 + C1) and matches the expected value (B1 + C1) of the intermediate storage unit 322. The attached data type K1 is specified as the next data type, and the intermediate-side type information in the intermediate-side storage unit 322 is updated to indicate this data type (S1562). Similarly to the main control board 310, the intermediate unit 202A shows the change target pattern P3 with respect to the change target pattern information 1040, and the inspection value (A1 + C1) of the authentication information 1020 with which the authentication has been established. Since the switching method “1 advance” is associated, the change target pattern P3 is switched to the change target pattern P4, and the change target pattern P4 is stored in the RAM 213 or the like (S1563). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P4.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1582).

  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 (S1516). 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 (S1517). The main control board 310 generates authentication data for the inspection value (A2 + C1) associated with the data type K2 (S1518). 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 intermediate part 202A of the peripheral board 330 (S1519). The main control board 310 indicates the change target pattern 4 with respect to the change target pattern information 1040, and the current inspection value (A2 + C1) of the authentication data is associated with the switching method “2 advance”. Therefore, the change target pattern P4 is switched to the change target pattern P2, and the change target pattern P2 is stored in the RAM 213 or the like (S1520).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A2 + C1) from the main control board 310 (S1564), the intermediate type information in the intermediate storage section 322 indicates the authentication data. It is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A2 + C1) matches the two types of expected values stored in the intermediate storage unit 332, and the main control board based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the authentication result 310 is generated and stored in the intermediate storage unit 332 (S1565). Then, the intermediate unit 202A transmits an intermediate authentication result signal to which the intermediate authentication result information 1030 is added to the peripheral unit 202B of the peripheral board 330 (S1566). Further, when authentication is established, the intermediate unit 202A corresponds to the expected value (B2 + C1) because the authentication data is the inspection value (A2 + C1), and therefore matches the expected value (B2 + C1) of the intermediate storage unit 322. The attached data type K2 is specified as the next data type, and the intermediate side type information in the intermediate storage unit 322 is updated to indicate this data type (S1567). Similarly to the main control board 310, the intermediate unit 202A shows the change target pattern P4 with respect to the change target pattern information 1040, and the inspection value (A2 + C1) of the authentication information 1020 for which the authentication has been established. Since the switching method “2 advance” is associated, the change target pattern P4 is switched to the change target pattern P2, and the change target pattern P2 is stored in the RAM 213 or the like (S1568). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P2.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1583).

  Subsequently, in FIG. 21, 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 (S1521). 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 (S1522). The main control board 310 randomly generates the expected value change data C2 for changing the inspection value and the expected value by a predetermined generation method (S1523), and the authentication information 1020 having the expected value change data. (C2) is generated, and the authentication information 1020 (C2) is transmitted to the intermediate portion 202A of the peripheral board 330 (S1524). Then, as shown in FIG. 14, the main control board 310 does not change the inspection value A1 because the change target pattern P2 indicates the inspection value A2, and the inspection value (A2 + C2) by the change method described above. (S1525).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (C2) from the main control board 310 (S1569), the intermediate type information in the intermediate storage section 322 indicates expected value change data. From the expected value change data in the data portion 1022 of the authentication information 1020 (C2), the expected value B2 defined by the change target pattern P2 shown in FIG. 14 is changed to the expected value (B2 + C2) by the change method described above (S1570). ). As a result, the inspection value A1 and inspection value (A2 + C2) of the main control board 310 and the expected value B1 and expected value (B2 + C2) of the peripheral board 330 are maintained at the same values. Then, the intermediate unit 202A specifies a data type K1 predetermined for generating expected value change data as the next data type, and the intermediate type information of the intermediate storage unit 322 indicates this data type. Is updated (S1571).

  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 (S1526). 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 (S1527). The main control board 310 generates authentication data for the inspection value (A1 + C2) associated with the data type K1 (S1528). Then, the main control board 310 generates authentication information 1020 (A1 + C2) having the authentication data, and transmits the authentication information 1020 (A1 + C2) to the intermediate portion 202A of the peripheral board 330 (S1529). The main control board 310 indicates the change target pattern P2 with respect to the change target pattern information 1040, and the current inspection value (A1 + C2) of the authentication data is associated with the switching method “advance one”. Therefore, the change target pattern P2 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1530).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A1 + C2) from the main control board 310 (S1572), the intermediate type information in the intermediate storage section 322 indicates authentication data. It is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C2) matches the two types of expected values stored in the intermediate storage unit 332, and the main control board based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the authentication result 310 is generated and stored in the intermediate storage unit 332 (S1573). Then, the intermediate unit 202A transmits an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto to the peripheral unit 202B of the peripheral board 330 (S1574). Further, when authentication is established, the intermediate unit 202A corresponds to the expected value (B1 + C2) because the authentication data is the inspection value (A1 + C2) and matches the expected value (B1 + C2) of the intermediate storage unit 322. The attached data type K1 is specified as the next data type, and the intermediate side type information in the intermediate side storage unit 322 is updated to indicate this data type (S1575). Similarly to the main control board 310, the intermediate unit 202A indicates the change target pattern P2 with respect to the change target pattern information 1040, and the inspection value (A1 + C2) of the authentication information 1020 with which the authentication has been established. Since the switching method “1 advance” is associated, the change target pattern P2 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1576). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P3.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1584). Thereafter, the same authentication process as described above is performed.

  According to the pachinko gaming machine 100 described above, two test values are associated with each of the two types of data of the authentication information 1020, and the main control unit 201 corresponds to the data type of the authentication information 1020 generated next time. Since the authentication data is generated with the inspection value, the authentication information 1020 including the authentication data is generated and transmitted to the peripheral portion, the peripheral portion associates the data type with the expected value. Since the authentication value of the main control unit 201 can be established and the data type of the authentication information to be received next time can be specified when the inspection value and the expected value of the authentication information 1020 match, Can prevent unauthorized use of authentication information. 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. Further, when the test value included in the authentication information 1020 matches the expected value, the intermediate unit 202A determines that the authentication information received next time is the expected value if the expected value changing data of the data type is associated with the expected value. Since the change data can be identified, the expected value can be changed with the expected value change data received from the main control unit 201 to match the inspection value of the main control unit 201. The inspection value and the expected value can be aligned and changed between 201 and the intermediate portion 202A, making analysis by an unauthorized analyst difficult. Furthermore, by preparing a plurality of change target patterns for defining the change target of the expected value change data for each of the two types of inspection values A1, A2 and expected values B1, B2, and switching them by a predetermined switching method. Since changes to the two types of inspection values A1 and A2 and expected values B1 and B2 are complicated, it is possible to make it difficult to analyze authentication information by an unauthorized analyst. In addition, since the intermediate unit 202A can detect that the authentication information is illegally used by the fraud analyst based on the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. Furthermore, since the intermediate unit 202A performs authentication processing on the main control unit 201 and transmits the intermediate authentication result to the peripheral unit 202B, the peripheral unit 202B simply refers to the intermediate authentication result without performing authentication processing. Therefore, the processing load on the CPU 241 in the peripheral portion 202B can be reduced. Further, since the two inspection values can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in processing load on the main control unit 201 can be prevented. Moreover, since the intermediate unit 202A transmits the control command from the main control unit 201 to the peripheral unit 202B as it is, the intermediate unit 202A can perform the authentication process and the peripheral unit 202B can perform the predetermined process. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, even if one type of authentication information 1020 is used, there is an effect that it is possible to make unauthorized analysis of the authentication information 1020 difficult.

  In the pachinko gaming machine 100 described above, a different switching method is associated with each of the two types of inspection values A1 and A2 on a one-to-one basis, and the switching method is switched according to the switching of the inspection value A. Since the switching method can also be switched randomly, and a plurality of change target patterns can be switched by the switching method, the inspection values A1, A2 and the expected values B1, B2 can be changed to irregular values, Their analysis can be made even more difficult.

  In the pachinko gaming machine 100 described above, since the change target patterns P1 to P4 are switched using the change target pattern information 1040 indicating two or more types of change target patterns P1 to P4, the inspection values A1 and A2 and the expected value Since the change target patterns P1 to P4 that are equal to or more than the number of B1 and B2 can be used, the changes to the inspection values A1 and A2 and the expected values B1 and B2 can be further complicated to make analysis difficult. .

  Further, in the pachinko gaming machine 100 described above, since the main control unit 201 randomly generates expected value change data, both the inspection value of the main control unit 201 and the expected value of the intermediate unit 202A are obtained. Since it can be changed at random, the analysis of authentication information 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 intermediate unit 202A are determined in advance by setting the expected value change data to a test value that is a predetermined initial value and a correction value that changes the expected value. Since it is only necessary to change the inspection value and the expected value with the data for changing the expected value, the changing process can be simplified.

  In the pachinko gaming machine 100 described above, the expected value change data can be changed by accumulating the test value and the expected value by changing the test value and the expected value to be changed last time. In addition, the analysis of the expected value can be made more difficult, and unauthorized use of the inspection value and the expected value can be prevented.

  In the pachinko gaming machine 100 described above, an expected value that is different from the inspection value of the main control unit 201 is stored in the intermediate unit 202A in advance, and the expected value is changed to absorb the difference between the inspection value and the expected value. The data is generated by the main control unit 201 and transmitted to the intermediate unit 202A, so that the intermediate unit 202A changes the expected value with the expected value change data, thereby matching the expected value with the inspection value of the main control unit 201. Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.

[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 intermediate unit 202A, an effect control unit 202B, and a prize ball control unit 203. As shown in FIG. 20, 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 intermediate unit 202A and the effect control unit 202B described above. 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 determination unit 312, the authentication data generation unit 314, the expected value change data generation unit 315, the main control side switching unit 316, the main control side change unit 317, and the authentication information generation. A unit 318, a main control side transmission unit 319, an update unit 320, and a selection unit 321.

  The selection unit 321 corresponds to the selection unit of the present invention, and randomly selects one inspection value A from the two types of inspection values A1 and A2 stored in the data storage unit 311. The selection unit 321 randomly selects one inspection value using a random number or the like. The selection method of the selection unit 321 is preferably such that the selection pattern is irregular in order to prevent unauthorized analysis.

  The determination unit 312 described above determines the data types K1 and K2 (see FIG. 13) associated with the inspection value A selected by the selection unit 321 as the data types of the authentication information 1020 that the main control board 310 generates next time. . Specifically, when the inspection value A1 is selected, the next time is determined as the data type K1, and when the inspection value A2 is selected, the next time is determined as the data type K2. The authentication data generation unit 314 described above generates authentication data having the inspection value selected by the selection unit 321 when the type information indicates authentication data.

  The main control side switching unit 316 described above switches the plurality of types of change target patterns P <b> 1 to P <b> 4 by a switching method associated with the inspection value A randomly selected by the selection unit 321. Therefore, since the change target patterns P1 to P4 can be switched irregularly by switching the switching method according to the selection of the inspection value A, illegal analysis can be made difficult.

  When the pachinko gaming machine 100 according to the second embodiment uses two types of inspection values for 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 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, thereby changing the inspection value A configuration is employed in which the main control board 310 is authenticated based on the expected value. Moreover, since the value to be changed among the two types of inspection values can be defined by a plurality of types of change target patterns, and these change target patterns can be switched and changed, analysis of the changed inspection values and expected values can be performed. Can be 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.

  Subsequently, the intermediate unit 202A of the peripheral board 330 illustrated in FIG. 20 includes the above-described intermediate side reception unit 331, intermediate side storage unit 332, intermediate authentication result data generation unit 333, and intermediate side transmission unit 334 as in the first embodiment. , An intermediate side switching unit 335, an intermediate side changing unit 336, and a specifying unit 337. The peripheral portion 202B also includes the peripheral-side receiving portion 351 and the processing portion 352 described above as in the first embodiment. 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.

  In the second embodiment, the CPU 211 of the main control board 310 is the first computer in the claims, and the CPU 231 of the intermediate section 202A of the peripheral board 330 is the second computer in the claims, and the CPU 241 of the effect control section 202B of the peripheral board 330. Will be described as functioning as the third computer in the claims. The ROM 212 of the main control board 310 includes a determination unit, an authentication data generation unit, an expected value change data generation unit, a main control side switching unit, a main control side change unit, and authentication information. A main control side authentication program for causing various functions such as generating means, main control side transmitting means, updating means, and selecting means to function is stored. The ROM 232 of the intermediate portion 202A of the peripheral board 330 includes the intermediate computer receiving means, the intermediate authentication result data generating means, the intermediate transmitting means, the intermediate switching means, the intermediate updating means, and the identification of the second computer. The intermediate side authentication program for functioning as various means such as means is stored. Further, the ROM 242 of the peripheral portion 202B of the peripheral board 330 stores a peripheral side authentication program for causing the third computer to function as various means such as peripheral side receiving means and processing means in the claims. That is, the authentication program of the present invention is constituted by the main control side authentication program, the intermediate side authentication program, and the peripheral side authentication program.

(Processing for sending and receiving authentication information signals)
Hereinafter, a communication example of the authentication information signal performed between the main control unit 201 and the intermediate unit 202A 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 an authenticated process shown in FIG. 23, and determines whether or not it is a predetermined authentication timing in step S1601. If the main control unit 201 determines that it is not the authentication timing (S1601: No), the main control unit 201 proceeds to the process of step S1615. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1601: Yes), the process proceeds to step S1602.

  In step S1602, 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 S1603. 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 S1603, 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 (S1603: No), the main control unit 201 proceeds to the process of step S1604. In step S1604, the main control unit 201 randomly generates expected value change data for changing the inspection value and the expected value using a predetermined generation method, and generates the generated expected value change data. It memorize | stores in the data memory | storage part 311 grade | etc., And progresses to the process of step S1605 after that. An example of a method for generating expected value change data is to generate the expected value change data by using the generation method using a random number or a pattern table.

  In step S <b> 1605, the main control unit 201 uses the change method described above for the expected value change data stored in the data storage unit 311 for the test value indicated by the current change target pattern among the two types of test values. Then, the process proceeds to step S1606. Note that the test value can be changed at various timings such as when the expected value change data is generated and when the authentication data is generated. In step S1606, the main control unit 201 determines a data type K1 predetermined for generating expected value change data as the next data type, stores it in the RAM 213, etc., and then performs the processing in step S1611. move on. The predetermined data type is predetermined between the main control board 310 and the intermediate portion 202A of the peripheral board 330.

  On the other hand, when the main control unit 201 determines in step S1603 that the data type is authentication data (S1603: Yes), in step S1607, the main control unit 201 selects one of the two types of inspection values stored in the data storage unit 311. A test value is randomly selected and stored in the RAM 213 or the like. In step S1608, authentication data having the selected test value is generated and stored in the RAM 213 or the like, and then the process proceeds to step S1609. As a result, authentication data having one of two types of inspection values is created.

  In step S <b> 1609, the main control unit 201 switches the change target pattern with a switching method associated with the selected inspection value for a plurality of types of change target patterns indicated by the change target pattern information, and the changed change target pattern. Is stored in the RAM 213 or the like, and then the process proceeds to step S1610. When a known pointer is used as a change target pattern switching method, the change target pattern indicated by the current pointer is stored in the RAM 213 or the like, and the pointer is moved and switched based on the switching method. In step S1610, the main control unit 201 determines the data type associated with the selected inspection value as the data type of the authentication information 1020 to be generated next time, and then proceeds to the process of step S1611.

  In step S1611, 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 S1612.

  In step S1612, the main control unit 201 encrypts the generated authentication information 1020 using a predetermined encryption method with the intermediate unit 202A. In step S1613, 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 transmitting unit 319 to the intermediate unit 202A of the peripheral board 330, and then the process proceeds to step S1614. If encryption is not required between the main control unit 201 and the intermediate unit 202A, the processing in step S1612 is deleted, and the authentication information 1020 is transmitted as it is to the intermediate unit 202A. In step S1614, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1606 or step S1610, and then proceeds to the process in step S1615.

  In step S1615, 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 (S1615: No), the main control unit 201 returns to the process of step S1601 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1615: Yes), the process according to this flowchart ends.

  Subsequently, the authentication information signal reception processing procedure performed by the CPU 231 (second computer) of the intermediate unit 202A in the peripheral board 330, and the control signal and the intermediate authentication performed by the CPU 241 (third computer) of the peripheral unit 202B. As the result signal reception processing procedure, the authentication side processing shown in FIG. 17 of the first embodiment and the processing shown in FIG.

(Example 2 of authentication processing procedure using authentication information)
Next, an example of the authentication processing procedure 2 in the case of performing authentication of the main control board 310 by switching the data types K1 and K2 shown in FIG. 12 will be described with reference to FIGS. In the present embodiment, only the case where the change method is “+” will be described in order to simplify the description.

  In FIG. 24, the main control board 310 which is the person to be authenticated sets a predetermined data type K1 for this time (S1701). The main control board 310 randomly selects one inspection value A2 from the two types of inspection values A1 and A2 in the data storage unit 311 (S1702), and generates authentication data for the inspection value A2 (S1703). The main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the peripheral board 330 (S1704). Then, as shown in FIG. 13, the main control unit 310 determines the data type K2 associated with the selected inspection value A2 as the data type K2 for the authentication information 1020 to be generated next time, and updates the type information. (S1705). Then, the main control board 310 indicates the change target pattern P1 as an initial setting with respect to the change target pattern information 1040 shown in FIG. 14, and the inspection value A2 of the acceptance data is as shown in FIG. Since the switching method “2 advance” is associated, the change target pattern P1 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1706).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A2) from the main control board 310 (S1751), the initial intermediate type information indicates the authentication data, so the authentication information 1020 ( A2) It is determined whether or not the authentication data in the data section 1022 and the two types of expected values stored in the intermediate storage section 332 match, and the authentication result of the main control board 310 based on the determination result The intermediate authentication result information 1030 having intermediate authentication result data indicating that is generated and stored in the intermediate storage unit 332 (S1752). Then, the intermediate unit 202A transmits an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto to the peripheral unit 202B of the peripheral board 330 (S1753). When the authentication is established, the intermediate unit 202A is the inspection value A2, and therefore matches the expected value B2 of the intermediate storage unit 322. Therefore, the data type K2 associated with the expected value B2 Is identified as the next data type, and the intermediate type information in the intermediate storage unit 322 is updated to indicate this data type (S1754). Similarly to the main control board 310, the intermediate unit 202A indicates the change target pattern P1 as an initial setting for the change target pattern information 1040, and sets the inspection value A2 of the authentication information 1020 for which the authentication has been established. Since the switching method “2 advance” is associated, the change target pattern P1 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1755). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P3.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined signal corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1781).

  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 (S1707). Since the type information indicates the data type K2, the main control board 310 randomly generates the expected value changing data C1 for changing the inspection value and the expected value by a predetermined generation method (S1708). ), Authentication information 1020 (C1) having the expected value change data C1 is generated, and the authentication information 1020 (C1) is transmitted to the intermediate portion 202A of the peripheral board 330 (S1709). Then, the main control unit 310 determines 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 (S1710). Then, as shown in FIG. 14, the main control board 310 changes the inspection values A1 and A2 indicated by the change target pattern P3 to the inspection value (A1 + C1) and the inspection value (A2 + C1) by the above-described changing method (S1711).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (C1) from the main control board 310 (S1756), the intermediate type information in the intermediate storage section 322 indicates expected value change data. From the expected value change data C1 of the data portion 1022 of the authentication information 1020 (C1), the expected values B1 and B2 defined by the change target pattern P3 shown in FIG. The value is changed to (B2 + C1) (S1757). As a result, the inspection value (A1 + C1) and inspection value (A2 + C1) of the main control board 310 and the expected value (B1 + C1) and the expected value (B2 + C1) of the peripheral board 330 are maintained. Then, the intermediate unit 202A specifies a data type K1 that is predetermined for generating the expected value change data as the next data type, and the intermediate type of the intermediate storage unit 322 indicates the data type K1. Information is updated (S1757).

  Subsequently, in FIG. 25, 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 (S1712). The main control board 310 randomly selects one inspection value A1 + C1 from the two types of inspection values A1 + C1 and A2 + C1 in the data storage unit 311 (S1713), and generates authentication data for the inspection value A1 + C1 (S1714). 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 intermediate section 202A of the peripheral board 330 (S1715). Then, the main control unit 310 updates the authentication information 1020 to be generated next time as the data type K1 for the data type K1 associated with the selected inspection value A1 + C1 and updates the type information (S1716). The main control board 310 indicates the change target pattern P3 with respect to the change target pattern information 1040, and the current inspection value (A1 + C1) of the authentication data is associated with the switching method “advance one”. Therefore, the change target pattern P3 is switched to the change target pattern P4, and the change target pattern P4 is stored in the RAM 213 or the like (S1717).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A1 + C1) from the main control board 310 (S1759), the intermediate type information in the intermediate storage section 322 indicates the authentication data. It is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C1) matches the two types of expected values stored in the intermediate storage unit 332, and the main control board based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the authentication result 310 is generated and stored in the intermediate storage unit 332 (S1760). Then, the intermediate unit 202A transmits an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto to the peripheral unit 202B of the peripheral board 330 (S1761). When the authentication is established, the intermediate unit 202A corresponds to the expected value (B1 + C1) because the authentication data matches the expected value (B1 + C1) of the intermediate storage unit 322 because the authentication data is the inspection value (A1 + C1). The attached data type K1 is specified as the next data type, and the intermediate side type information in the intermediate storage unit 322 is updated to indicate this data type (S1762). Similarly to the main control board 310, the intermediate unit 202A shows the change target pattern P3 with respect to the change target pattern information 1040, and the inspection value (A1 + C1) of the authentication information 1020 with which the authentication has been established. Since the switching method “advance 1” is associated, the change target pattern P3 is switched to the change target pattern P4, and the change target pattern P4 is stored in the RAM 213 or the like (S1763). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P4.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1782).

  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 (S1718). The main control board 310 randomly selects one inspection value A2 + C1 from the two types of inspection values A1 + C1 and A2 + C1 in the data storage unit 311 (S1719), and generates authentication data for the inspection value A2 + C1 (S1720). 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 intermediate part 202A of the peripheral board 330 (S1721). Then, the main control unit 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 inspection value A2 + C1 and updates the type information (S1722). The main control board 310 indicates the change target pattern P4 with respect to the change target pattern information 1040, and the current inspection value (A2 + C1) of the authentication data is associated with the switching method “2 advance”. Therefore, the change target pattern P4 is switched to the change target pattern P2, and the change target pattern P2 is stored in the RAM 213 or the like (S1723).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A2 + C1) from the main control board 310 (S1764), the intermediate side type information of the intermediate storage section 322 indicates the authentication data. It is determined whether the authentication data in the data portion 1022 of the authentication information 1020 (A2 + C1) matches the two types of expected values stored in the intermediate storage unit 332, and the main control board based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the authentication result 310 is generated and stored in the intermediate storage unit 332 (S1765). Then, the intermediate unit 202A transmits an intermediate authentication result signal added with the intermediate authentication result information 1030 to the peripheral unit 202B of the peripheral board 330 (S1766). When the authentication is established, the intermediate unit 202A corresponds to the expected value (B2 + C1) because the authentication data is the inspection value (A2 + C1), and therefore matches the expected value (B2 + C1) of the intermediate storage unit 322. The attached data type K2 is specified as the next data type, and the intermediate side type information in the intermediate side storage unit 322 is updated to indicate this data type (S1767). Similarly to the main control board 310, the intermediate unit 202A shows the change target pattern P4 with respect to the change target pattern information 1040, and the inspection value (A2 + C1) of the authentication information 1020 for which the authentication has been established. Since the switching method “2 advance” is associated, the change target pattern P4 is switched to the change target pattern P2, and the change target pattern P2 is stored in the RAM 213 or the like (S1768). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P2.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined process corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1783).

  Subsequently, in FIG. 26, 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 (S1724). Since the type information indicates the data type K2, the main control board 310 randomly generates the expected value changing data C2 for changing the inspection value and the expected value by a predetermined generation method (S1725). ), Authentication information 1020 (C2) having the expected value change data C2 is generated, and the authentication information 1020 (C2) is transmitted to the intermediate portion 202A of the peripheral board 330 (S1726). Then, the main control unit 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 (S1727). Then, as shown in FIG. 14, the main control board 310 does not change the inspection value A1 because the change target pattern P2 indicates the inspection value A2, and changes it to the inspection value (A2 + C2) by the above-described change method. (S1728).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (C2) from the main control board 310 (S1769), the intermediate type information in the intermediate storage section 322 indicates expected value change data. From the expected value change data C2 in the data portion 1022 of the authentication information 1020 (C2), the expected value B2 defined by the change target pattern P2 shown in FIG. 14 is changed to the expected value (B2 + C2) by the above-described change method ( S1770). As a result, the inspection value A1 and inspection value (A2 + C2) of the main control board 310 and the expected value B1 and expected value (B2 + C2) of the peripheral board 330 are maintained at the same values. Then, the intermediate unit 202A specifies a data type K1 that is predetermined for generating the expected value change data as the next data type, and the intermediate type of the intermediate storage unit 322 indicates the data type K1. Information is updated (S1771).

  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 (S1729). The main control board 310 randomly selects one inspection value A1 + C2 from the two types of inspection values A1 + C2 and A2 + C2 in the data storage unit 311 (S1730), and generates authentication data for the inspection value A1 + C2 (S1731). The main control board 310 generates authentication information 1020 (A1 + C2) having the authentication data, and transmits the authentication information 1020 (A1 + C2) to the intermediate part 202A of the peripheral board 330 (S1732). Then, the main control unit 310 updates the authentication information 1020 to be generated next time as the data type K1 for the data type K1 associated with the selected inspection value A1 + C2, and updates the type information (S1733). The main control board 310 indicates the change target pattern P2 with respect to the change target pattern information 1040, and the current inspection value (A1 + C2) of the authentication data is associated with the switching method “advance one”. Therefore, the change target pattern P2 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1734).

  On the other hand, when the intermediate section 202A of the peripheral board 330 receives the authentication information 1020 (A1 + C2) from the main control board 310 (S1772), the intermediate type information in the intermediate storage section 322 indicates authentication data. It is determined whether or not the authentication data in the data portion 1022 of the authentication information 1020 (A1 + C2) matches the two types of expected values stored in the intermediate storage unit 332, and the main control board based on the determination result Intermediate authentication result information 1030 having intermediate authentication result data indicating the authentication result 310 is generated and stored in the intermediate storage unit 332 (S1773). Then, the intermediate unit 202A transmits an intermediate authentication result signal with the intermediate authentication result information 1030 added thereto to the peripheral unit 202B of the peripheral board 330 (S1774). When the authentication is established, the intermediate unit 202A corresponds to the expected value (B1 + C2) because the authentication data is the inspection value (A1 + C2), and therefore matches the expected value (B1 + C2) of the intermediate storage unit 322. The attached data type K1 is specified as the next data type, and the intermediate-side type information in the intermediate-side storage unit 322 is updated to indicate this data type (S1775). Similarly to the main control board 310, the intermediate unit 202A indicates the change target pattern P2 with respect to the change target pattern information 1040, and the inspection value (A1 + C2) of the authentication information 1020 with which the authentication has been established. Since the switching method “1 advance” is associated, the change target pattern P2 is switched to the change target pattern P3, and the change target pattern P3 is stored in the RAM 213 or the like (S1776). As a result, both the intermediate portion 202A of the main control board 310 and the peripheral board 330 are switched to the change target pattern P3.

  Further, the peripheral portion 202B of the peripheral board 330 receives the control received from the main control portion 201 via the intermediate portion 202A when the intermediate authentication result information 1030 of the intermediate authentication result signal received from the intermediate portion 202A indicates that authentication has been established. A predetermined signal corresponding to the command data 1001 and the accompanying data 1002 can be executed, and if the intermediate authentication result information 1030 does not indicate that authentication has been established, a notification signal is output (S1784). Thereafter, the same authentication process as described above is performed.

  According to the pachinko gaming machine 100 described above, as in the first embodiment, two inspection values are associated with each of the two types of data of the authentication information 1020, and the authentication information generated next time by the main control unit 201. Since the authentication data is generated with the inspection value corresponding to the data type 1020, and the authentication information 1020 having the authentication data is generated and transmitted to the peripheral part, the peripheral part sets the data type to the expected value. By associating the authentication information 1020, when the inspection value and the expected value of the authentication information 1020 match, the authentication of the main control unit 201 can be established and the data type of the authentication information to be received next time is specified Therefore, it is possible to prevent an unauthorized analyst from illegally using authentication information. 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. Further, when the test value included in the authentication information 1020 matches the expected value, the intermediate unit 202A determines that the authentication information received next time is the expected value if the expected value changing data of the data type is associated with the expected value. Since the change data can be identified, the expected value can be changed with the expected value change data received from the main control unit 201 to match the inspection value of the main control unit 201. The inspection value and the expected value can be aligned and changed between 201 and the intermediate portion 202A, making analysis by an unauthorized analyst difficult. Furthermore, by preparing a plurality of change target patterns for defining the change target of the expected value change data for each of the two types of inspection values A1, A2 and expected values B1, B2, and switching them by a predetermined switching method. Since changes to the two types of inspection values A1 and A2 and expected values B1 and B2 are complicated, it is possible to make it difficult to analyze authentication information by an unauthorized analyst. In addition, since the intermediate unit 202A can detect that the authentication information is illegally used by the fraud analyst based on the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. Furthermore, since the intermediate unit 202A performs authentication processing on the main control unit 201 and transmits the intermediate authentication result to the peripheral unit 202B, the peripheral unit 202B simply refers to the intermediate authentication result without performing authentication processing. Therefore, the processing load on the CPU 241 in the peripheral portion 202B can be reduced. Further, since the two inspection values can be stored in advance, it is not necessary to perform a complicated calculation when generating the authentication information, and an increase in processing load on the main control unit 201 can be prevented. Moreover, since the intermediate unit 202A transmits the control command from the main control unit 201 to the peripheral unit 202B as it is, the intermediate unit 202A can perform the authentication process and the peripheral unit 202B can perform the predetermined process. Thus, it is possible to prevent a delay from occurring in the predetermined processing in the peripheral portion 202B. Therefore, even if one type of authentication information 1020 is used, there is an effect that it is possible to make unauthorized analysis of the authentication information 1020 difficult.

  In the pachinko gaming machine 100 described above, a different switching method is associated with each of the two types of inspection values A1 and A2 on a one-to-one basis, and the switching method is switched according to the switching of the inspection value A. Since the switching method can also be switched randomly, and a plurality of change target patterns can be switched by the switching method, the inspection values A1, A2 and the expected values B1, B2 can be changed to irregular values, Their analysis can be made even more difficult.

  In the pachinko gaming machine 100 described above, since the change target pattern is switched using the change target pattern information 1040 indicating two or more types of change target patterns P1 to P4, the inspection values A1, A2 and the expected values B1, B2 Since more than the number of change target patterns P1 to P4 can be used, the changes to the inspection values A1 and A2 and the expected values B1 and B2 can be made more complicated and difficult to analyze.

  Further, in the pachinko gaming machine 100 described above, since the main control unit 201 randomly generates expected value change data, both the inspection value of the main control unit 201 and the expected value of the intermediate unit 202A are obtained. Since it can be changed at random, the analysis of authentication information by an unauthorized analyst can be made even more difficult.

  In the pachinko gaming machine 100 described above, the expected value changing data is a predetermined initial value and a correction value for changing the expected value and the expected value. Since the main control unit 201 and the intermediate unit 202A only need to change the predetermined inspection value and expected value with the expected value changing data, the changing process can be simplified.

  Furthermore, in the pachinko gaming machine 100 described above, the expected value change data can be changed by accumulating the test value and the expected value by changing the test value and the expected value to be changed last time. Analysis of inspection values and expected values can be made more difficult, and unauthorized use of inspection values and expected values can be prevented.

  In the pachinko gaming machine 100 described above, an expected value that is different from the inspection value of the main control unit 201 is stored in the intermediate unit 202A in advance, and an expected value for absorbing the difference between the inspection value and the expected value. If the main control unit 201 generates the change data and transmits the data to the intermediate unit 202A, the intermediate unit 202A changes the expected value with the expected value change data, thereby changing the expected value of the main control unit 201. Since it can be made to correspond with a test value, analysis and utilization of a test value and an expected value by an unauthorized analyst can be made difficult.

  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. Even in these gaming machines, the same effects as those of the above-described embodiments can be obtained by configuring similarly to the above-described embodiments.
