Abstract

PROBLEM TO BE SOLVED: To make illegal analysis of authentication information difficult even when authentication is performed with one kind of authentication information.SOLUTION: A main control part extracts an examination value corresponding to a decided data type of next time, and if type information is data for authentication, generates data for authentication having the extracted examination value. The main control part switches a change object pattern with a switching system, and if the type information is data for expectation value change, changes the examination value shown by the change object pattern with the data for expectation value change. The main control part generates authentication information having the data for authentication or the data for expectation value change and sends the authentication information to a peripheral part. On the other hand, if the data type of type information at peripheral side is the data for expectation value change, the peripheral part performs authentication of the main control part by comparing the data for authentication of the received authentication information with the expectation value. The peripheral part switches the change object pattern with the switching system, and if the data type shows the data for expectation value change, changes the expectation value which corresponds to the examination value shown by the change object pattern with the data for expectation value change.

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.

  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.

An authentication step of authenticating the main control unit by comparing with expected values of types, and switching the plurality of types of change target patterns same as the main control unit by the predetermined switching method of the main control side changing step And when the data type of the peripheral side type information indicates the expected value change data, the authentication information indicates the expected value that matches the inspection value indicated by the changed change target pattern. The peripheral side changing step for changing based on the expected value changing data and the authentication corresponding to the authentication data of the authentication information when the authentication of the main control unit is established. And a specifying step of specifying the data type as the next data type and updating the peripheral side type information.

  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, and based on the generated expected value change data The inspection value stored in the inspection value storage means is changed. 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. The main control unit can generate authentication information having the generated authentication data or expected value change data, and can transmit the generated authentication information to the peripheral unit. Then, the main control unit updates the type information stored in the type information storage means so as to indicate the determined next data type. On the other hand, the peripheral unit compares the authentication data of the authentication information received from the main control unit with the two types of expected values when the data type of the peripheral side type information indicates the authentication data. Can be authenticated. When the authentication of the main control unit is established, the peripheral unit specifies the data type associated with the expected value that matches the authentication data of the authentication information as the next data type and updates the peripheral type information can do. In addition, when the peripheral unit switches the same multiple types of change target patterns as the main control unit using a predetermined switching method of the main control unit, and the data type of the peripheral 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.

  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, and the authentication information including the authentication data is generated and transmitted to the peripheral part, the peripheral part 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 inspection value and the expected value of the authentication information match the expected value, if the expected value change data of the data type is associated with the expected value, the authentication information received next time is the expected value change 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. In addition, since the peripheral part can detect that the authentication information has been used illegally by the fraud analyst based on the data type of the authentication information, the authentication strength of the authentication information can be increased. Therefore, even if authentication is performed with one type of authentication information, it is possible to make it difficult to perform illegal analysis of the authentication information.

  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 peripheral part. 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 test value that is a predetermined initial value and a correction value that changes the expected value, the main control unit and the peripheral 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 above-described gaming machine, the expected value changing data for absorbing the difference between the inspection value and the expected value is stored in the peripheral portion in advance and the expected value changing data for absorbing the difference between the inspection value and the expected value is the main control. Since the part has generated and transmitted to the peripheral 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 peripheral part. Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.

The configuration of the board of the pachinko gaming machine 100 is not limited to this. For example, the prize ball control unit 203 has various different configurations such as being provided on the same printed circuit board as the main control unit 201 or the effect control unit 202. be able to.

(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 change unit 317, the authentication information generation unit 318, the transmission unit 319, and the update 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 peripheral unit. Generate irregularly by executing, or generate 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 expected values of the peripheral substrate 330 is generated, and the expected value change data is stored in the data storage unit 311 or the like. 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 transmission unit 319 corresponds to a transmission unit of the present invention, and transmits each of the authentication information generated by the authentication information generation unit 318 and the control command data to the peripheral board (peripheral unit) 330 individually at different timings. Then, the transmission unit 319 of the present embodiment transmits control command data from the main control board 310 to the peripheral board 330 as a control signal. For example, the transmission unit 319 transmits the authentication information to the peripheral board 330 as an authentication information signal that is a signal different from the control signal transmitted from the main control board 310 to the peripheral board 330. 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 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 main control is performed based on the changed inspection value and expected value. A configuration for performing authentication of the substrate 310 is employed. 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 functions as peripheral parts such as the effect control unit 202 and the prize ball control unit 203 described above will be described. As shown in FIG. 3, the peripheral board 330 includes a receiving unit 331, a peripheral side storage unit 332, an authentication unit 333, a peripheral side switching unit 334, a peripheral side changing unit 335, and a specifying unit 336.

  The receiving unit 331 corresponds to a receiving unit of the present invention, and receives each of authentication information and control command data transmitted by the main control board 310. The 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. The receiving unit 331 receives control command data from the main control board 310 by receiving the control signal.

  The peripheral side storage unit 332 corresponds to the expected value storage unit and the peripheral side type information storage unit of the present invention. The peripheral-side storage unit 332 has two expectations corresponding to 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. As a result, if the authentication data set in the authentication information matches the expected value, 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 peripheral 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 peripheral storage unit 332 stores the type data indicating the two types of data in association with the expected value, thereby specifying the data type from the expected value.

  The peripheral side storage unit 332 stores peripheral type information indicating the data type of the current authentication information. The peripheral 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 peripheral board 330 can grasp the data type of the received authentication information in advance by referring to the peripheral side type information before receiving the authentication information from the main control board 310.

  The peripheral side storage unit 332 stores in advance the same change target pattern information as that of the main control board 310 described above. In the peripheral storage unit 332, each of the two expected values described above is associated with the same two types of switching methods as those of 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 authentication unit 333 corresponds to the authentication unit of the present invention. When the data type of the peripheral side type information indicates the authentication data, the authentication value that is the authentication data is stored in the peripheral side storage unit 332. The main control board 310 is authenticated by comparing with the expected value. As an example of the authentication method of the authentication 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 and does not match. In this case, authentication is not established.

  The peripheral side switching unit 334 switches a plurality of types of change target patterns that are the same as the main control unit 201 by the predetermined switching method of the main control side switching unit 316 described above. The peripheral side switching unit 334 switches the change target pattern with 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 peripheral side changing unit 335 corresponds to the peripheral side changing means of the present invention, and when the data type of the peripheral side type information indicates the expected value changing data, the change made by the peripheral side switching unit 334 is changed. The expected value of the peripheral storage unit 332 that matches the inspection value indicated by the target pattern is changed based on the expected value change data of the authentication information. The peripheral side changing unit 335 changes the expected value indicated by the change target pattern using the same change method and expected value changing data as the main control side changing unit 317 of the main control board 310. Then, if the data type of the peripheral side type information indicates the expected value change data, the peripheral side changing unit 335 receives the incorrect authentication information, and the expected value indicated by the change target pattern with the incorrect data. Is changed to a value different from the inspection value of the main control board 310, and authentication of subsequent authentication information is not established.

  The identification unit 336 corresponds to the identification unit of the present invention. When the authentication of the main control board 310 is established by the authentication unit 333, the data type associated with the expected value that matches the inspection value constituting the authentication data Is identified as the next data type, and the peripheral side type information stored in the peripheral side storage unit 332 is updated so as to be the specified next data type.

  In the present embodiment, a case will be described in which the CPU 211 of the main control board 310 functions as the first computer in the claims and each of the CPUs 241 and 281 of the peripheral board 330 functions as the second computer in the claims. The ROM 212 of the main control board 310 includes a determination unit, an inspection value extraction unit, an authentication data generation unit, an expected value change data generation unit, a main control side switching unit, and a main control side. A main control side authentication program for functioning as various means such as changing means, authentication information generating means, transmitting means, and updating means is stored. In addition, each of the ROMs 242 and 282 of the peripheral board 330 causes the second computer to function as various means such as receiving means, authentication means, peripheral side switching means, peripheral side changing means, and specifying means in the claims. The peripheral authentication program is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program and the peripheral side authentication program.

(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 202 every time a game ball wins the start winning opening 105, and the effect control unit 202 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 202 when the occurrence of the jackpot is determined, and the effect control unit 202 aligns the predetermined symbols and stops the variable display, Control is performed to open the special winning opening 109. The effect control unit 202 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 202 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 202. That is, in the description of FIG. 4 to FIG. 9, “send command” means “send a control signal including data (control command data) indicating the command”. The presence or absence of accompanying 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 202 and the prize ball control unit 203, and the process proceeds to step S403. When the power-on command is transmitted by this process, the effect control unit 202 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 0 (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 202, 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), it transmits a jackpot reach command (symbol variation command) to the effect control unit 202 in step S413. In step S414, the main control unit 201 determines whether or not the symbol variation time has elapsed. When determining that the symbol variation time has not elapsed (S414: No), the main control unit 201 repeats this determination process to wait for the symbol variation time to elapse. On the other hand, if the main control unit 201 determines that the symbol variation time has elapsed (S414: Yes), in step S415, the main control unit 201 transmits a symbol stop command to the effect control unit 202, and the process proceeds to step S416.

  In step S416, the main control unit 201 transmits a jackpot start command to the effect control unit 202. 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 202. To do. When the transmission of the jackpot command for all rounds is completed, the main control unit 201 transmits the jackpot end command to the effect control unit 202 in step S418, and proceeds to the process of step S422.

  If the main control unit 201 determines in step S412 that the random number is not a big hit random number (S412: No), in step S419, the main control unit 201 transmits an outlier reach command (design variation command) to the effect control unit 202, and in step S420. 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 202, and the process proceeds to 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 202, and ends the process according to this flowchart.

  Next, 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 202 in the pachinko gaming machine 100 is shown in FIG. 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, description will be given of a process when the symbol changes (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.

  First, the symbol variation process by the effect control unit 202 will be described with reference to the flowchart shown in FIG. The effect control unit 202 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 202 repeats this determination process to wait for the symbol variation command to be received. On the other hand, when it is determined that the symbol variation command has been received (S701: Yes), the effect control unit 202 acquires a random effect selection random number in step S702, and in step S703, based on the acquired random number, The type is selected, and the process proceeds to step S704. In step S704, the effect control unit 202 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 202 determines whether the effect time has elapsed. If the effect control unit 202 determines that the effect time has elapsed (S705: Yes), the effect control unit 202 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 202 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 production | presentation control part 202 not receiving the symbol stop command (S706: No), it returns to the process of step S705 and repeats a series of processes. On the other hand, when it determines with the production | presentation control part 202 having received the symbol stop command (S706: Yes), in step S707, the production | generation stop command is transmitted with respect to the lamp | ramp control part 251 and the audio | voice control part 252, and this flowchart. The process ends.

  Next, the big hitting process by the effect control unit 202 will be described with reference to the flowchart shown in FIG. The effect control unit 202 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 202 repeats this determination process to wait for reception of the jackpot start command. On the other hand, when determining that the jackpot start command has been received (S801: Yes), the effect control unit 202 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 202 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 202 repeats this determination process to wait for reception of the jackpot command. On the other hand, when determining that the jackpot command has been received (S803: Yes), the effect control unit 202 rounds corresponding to the round jackpot commands received by the lamp control unit 251 and 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 202 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 202 repeats this determination process to wait for reception of the jackpot end command. On the other hand, if it is determined that the jackpot end command has been received (S805: Yes), the effect control unit 202 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 202 (during symbol variation) will be described. Then, the lamp control unit 251 determines whether or not an effect start command has been received from the effect control unit 202 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 S <b> 906, the lamp control unit 251 determines whether an effect stop command has been received from the effect control unit 202. 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, a description will be given on the assumption that the main control unit 201 outputs an authentication information signal to the peripheral unit to transmit the authentication information from the main control unit 201 to the peripheral unit.

  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 peripheral part can identify whether or not the authentication information 1020 is based on the identification part 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.

(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 is 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 peripheral board 330 and changes the inspection value A1 that is the initial value with the correction value C1 to check the inspection value A1 + C1. The inspection value A2, which is the initial value, is changed with the correction value C1 to obtain the inspection value A2 + C1. On the other hand, when 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 the correction value C1. Change to the 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, the inspection value A2 + C1 of the main control board 310 and the expected value B1 + C1, the expected value B2 + C1 of the peripheral board 330 match. In this case, since the peripheral board 330 can determine that the inspection values A1 + C1 and A2 + C1 of the authentication information received from the main control board 310 are authentic, 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 peripheral board 330, and the inspection value A1 that is an initial value is the correction value C2. The inspection value A1 + C2 is changed and the inspection value A2 which is the initial value is changed with the correction value C2 to obtain the inspection value A2 + C2. On the other hand, when 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 with the correction value C2, and the expected value B1 + C1 and the expected value B2 that is the initial value are set with the correction value C2. Change to the 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, inspection value A2 + C2 of the main control board 310 and the expected value B1 + C2, expected value B2 + C2 of the peripheral board 330 match. In this case, since the peripheral board 330 can determine that the inspection values A1 + C2 and A2 + C2 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 same change is made for the third and subsequent changes.

  Next, a description will be given of a modification example in which when the inspection value A1 of the initial value on the main control board 310 and the expected value B0 of the initial value on the peripheral board 330 do not match (A1 ≠ B0), they are changed by the correction value Cn. To do. 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 peripheral board 330. On the other hand, when 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 peripheral board 330, and changes the inspection value A1 that is the initial value by the correction value C1 to check the inspection value A1 + C1. And On the other hand, when 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 by the same correction value C1, the peripheral board is obtained when the inspection value A1 + C1 of the main control board 310 and the expected value B1 + C1 of the peripheral board 330 match. Since 330 can determine that the inspection value A1 + C1 of the authentication information received from the main control board 310 is valid, 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 inspection value A1 of the initial value on the main control board 310 and the expected value B0 of the initial value on the peripheral board 330 do not match (A1 ≠ B0), another modification example in which they are changed by the correction value Cn. Will be explained. 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 peripheral board 330 and the inspection which is the initial value. The value A1 is changed with the correction value C1 to obtain the inspection value A1 + C1. On the other hand, when the peripheral board 330 receives the correction value C1 from the main control board 310, 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 peripheral board 330. The peripheral board 330 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 peripheral board 330, and changes the inspection value A11, which is an initial value, by the coefficient value F1 to check the inspection value A12. The inspection value A21 that is the initial value is changed by the coefficient value F1 to obtain the inspection value A22. On the other hand, when 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, the expected value B12, and the expected value B21 that is the initial value is the coefficient value F1. Change to the expected value B22. Therefore, 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 peripheral board 330 match. In this case, since the peripheral board 330 can determine that the inspection values A12 and A22 of the authentication information received from the main control board 310 are authentic, 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 peripheral board 330, and the inspection values A12 and A22 changed last time with the coefficient value F2. Change to inspection values A13 and A23. On the other hand, when 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 peripheral board 330 match. In addition, since the peripheral board 330 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 generates. With such an embodiment, the main control board 310 can eliminate the need to store the expected value B of the peripheral board 330.

  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 peripheral board 330, and a plurality of types of changes indicated by the change target pattern information are stored. A case where the target pattern is switched synchronously on both sides will be described.

  The change target pattern information 1030 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. The change target pattern P1 defines the inspection value A1 on the main control unit 201 side and the expected value B1 on the peripheral side as the change target. In the change target pattern P2, the main control unit 201 side defines the inspection value A2, and the peripheral 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 peripheral 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 this 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 1030 is configured only by the change target patterns P1 to P3. May be. In addition, for example, the change target pattern information 1030 may be configured to include 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. The switching method of the present embodiment indicates whether 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, or 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 A 1 and A 2 on the main control board 310 on a one-to-one basis. Each of the expected values B1 and B2 is associated one-on-one. 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”. Further, when the change of the expected value B2 is established when the change target pattern 1 is used, 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 peripheral board 330, the switching method switching is not matched, and thereafter, the authentication by the inspection value is not established, and the peripheral board 330 The occurrence of the fraud can be detected.

  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 as programs in each of the main control board 310 and the peripheral board 330. 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)
Below, the example of communication of the said authentication information signal performed between the main-control part 201 and a peripheral part is demonstrated. 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 the authentication processing shown in FIG. If the main control unit 201 determines that it is not the authentication timing (S1201: No), the process proceeds to step S1215. 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 determined in advance between the main control board 310 and 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, authentication information 1020 generated next time from the authentication data and the expected value change data. Are 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 the inspection values corresponding to the next data type determined in step S1207 from the two types of inspection values, stores them in the RAM 213, etc., 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 peripheral unit, and in step S1213, based on each of the encrypted authentication information 1020. Then, an authentication information signal is generated and transmitted from the transmission unit 319 to the peripheral unit, and then the process proceeds to step S1214. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1212 is deleted, and the authentication information 1020 is transmitted to the peripheral unit 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 process of 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.

  Next, a procedure of the authentication information signal reception process by the peripheral CPUs 241 and 281 (second computer) will be described with reference to the flowchart of FIG.

  When the peripheral unit executes the authentication-side process illustrated in FIG. 17, in step S <b> 1301, it is determined whether the reception unit 331 has received authentication information (authentication information signal) 1020 from the main control unit 201. If the peripheral unit determines that the authentication information 1020 has not been received (S1301: No), the process proceeds to step S1312. On the other hand, when it is determined that the authentication information 1020 has been received (S1301: Yes), the peripheral unit decrypts the received authentication information 1020 with a decryption method corresponding to the encryption method of the main control unit 201, and then step S1302 Proceed to the process. If encryption is not required between the main control unit 201 and the peripheral unit, the decryption process in step S1301 is deleted.

  In step S1302, the peripheral unit determines whether the peripheral type information in the peripheral storage unit 322 indicates authentication data. When it is determined that the peripheral portion indicates the authentication data (S1302: Yes), in step S1303, the authentication data is extracted from the data portion 1022 of the authentication information 1020 and stored in the peripheral side storage portion 332 or the like. Thereafter, the process proceeds to step S1304.

  In step S1304, the peripheral unit compares the authentication data with the two types of expected values stored in the peripheral side storage unit 322, and determines whether any of the expected values matches. If it is determined that the peripheral part matches the expected value (S1304: Yes), authentication is established for the main control unit 201 in step S1305, and the peripheral part is associated with the expected value that matches the authentication data in step S1306. The specified data type is specified, and the specified data type is set as the next data type in the peripheral side type information of the peripheral side storage unit 332, and then the process proceeds to step S1307.

  In step S1307, the peripheral unit 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 by the switching method. The plurality of types of change target patterns shown are switched, the changed change target patterns are stored in the RAM 243 and the like, and then the process proceeds to step S1312. The peripheral switching method is the same switching method as the main control unit 201.

  On the other hand, if it is determined that the peripheral portion does not match the expected value in step S1304 (S1304: No), authentication to the main control unit 201 is not established in step S1308, and in step S1309, for example, the speaker 262 (FIG. 2). The notification signal is output from the reference) and the processing according to this flowchart is terminated.

  On the other hand, if it is determined in step S1302 that the peripheral side type information does not indicate authentication data (S1302: No), the peripheral portion extracts expected value change data from the data portion 1022 of the authentication information 1020 in step S1310. In step S1311, the inspection value in the peripheral side storage unit 332 indicated by the current change target pattern is changed and stored by the above-described change method using the extracted expected value change data. Thereafter, 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 peripheral unit determines whether or not the pachinko gaming machine 100 is powered off. If it is determined that the power source is not turned off (S1312: No), the peripheral unit returns to the process of step S1301 and repeats a series of processes. On the other hand, when it is determined that the power source is turned off (S1312: Yes), the peripheral unit ends the process according to this flowchart.

(Example of authentication processing procedure using authentication information)
Next, an example of a procedure in the pachinko gaming machine 100 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. 18, the main control board 310, which is the person to be authenticated, sets a predetermined data type K1 for this time (S1401). 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 (S1402), and as shown in FIG. 13, the data type K2 The authentication data of the inspection value A2 associated with is generated (S1403). Then, the main control board 310 generates authentication information 1020 (A2) having the authentication data, and transmits the authentication information 1020 (A2) to the peripheral board 330 (S1404). Then, the main control board 310 indicates the change target pattern P1 as an initial setting with respect to the change target pattern information 1030 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 (S1405).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A2) from the main control board 310 (S1451), the initial peripheral side type information indicates the data for authentication, so the data of the authentication information 1020 (A2) It is determined whether or not the authentication data in the unit 1022 matches the two types of expected values stored in the peripheral storage unit 332, and the main control board 310 is authenticated (S1452). When the authentication is established, the peripheral substrate 330 matches the expected value B2 of the peripheral storage unit 322 because the authentication data is the inspection value A2, and therefore the data type K2 associated with the expected value B2 Is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 322 is updated to indicate the data type K2 (S1453). The peripheral board 330, like the main control board 310, shows the change target pattern P1 as the initial setting with respect to the change target pattern information 1030, and the inspection value A2 of the authentication information 1020 for which the authentication is 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 (S1454). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P3.

  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 (S1406). 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 (S1407). The main control board 310 randomly generates the expected value change data C1 for changing the inspection value and the expected value by a predetermined generation method (S1408), and the authentication information 1020 having the expected value change data. (C1) is generated, and the authentication information 1020 (C1) is transmitted to the peripheral board 330 (S1409). 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 (S1410).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (C1) from the main control board 310 (S1455), the peripheral side type information in the peripheral side storage unit 322 indicates the expected value change data. In the expected value changing data C1 of the data portion 1022 of 1020 (C1), the expected values B1 and B2 defined by the change target pattern P3 shown in FIG. 14 are expected values (B1 + C1) and expected values (B2 + C1) by the above-described changing method. (S1456). 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 peripheral board 330 specifies a data type K1 predetermined for generating expected value change data as the next data type, and the peripheral side type of the peripheral side storage unit 322 indicates the data type K1. Information is updated (S1457).

  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 (S1411). 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 (S1412). The main control board 310 generates authentication data for the inspection value (A1 + C1) associated with the data type K1 (S1413). Then, the main control board 310 generates authentication information 1020 (A1 + C1) having the authentication data, and transmits the authentication information 1020 (A1 + C1) to the peripheral board 330 (S1414). The main control board 310 indicates the change target pattern 3 with respect to the change target pattern information 1030, 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 (S1415).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A1 + C1) from the main control board 310 (S1458), since the peripheral type information in the peripheral storage unit 322 indicates the authentication data, the authentication information 1020 ( The main control board 310 is authenticated by determining whether or not the authentication data in the data portion 1022 (A1 + C1) and the two types of expected values stored in the peripheral storage portion 332 match (S1459). When the authentication is successful, the peripheral board 330 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 peripheral storage unit 322. The attached data type K1 is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 322 is updated to indicate the data type K1 (S1460). The peripheral board 330 shows the change target pattern P3 with respect to the change target pattern information 1030, as in the case of the main control board 310, and the inspection value (A1 + C1) of the authentication information 1020 for 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 (S1461). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P4.

  Subsequently, in FIG. 19, 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 (S1416). 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 (S1417). The main control board 310 generates authentication data for the inspection value (A2 + C1) associated with the data type K2 (S1418). Then, the main control board 310 generates authentication information 1020 (A2 + C1) having the authentication data, and transmits the authentication information 1020 (A2 + C1) to the peripheral board 330 (S1419). The main control board 310 shows the change target pattern P4 with respect to the change target pattern information 1030, 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 (S1420).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A2 + C1) from the main control board 310 (S1462), the peripheral side type information in the peripheral side storage unit 322 indicates the authentication data. The main control board 310 is authenticated by determining whether or not the authentication data in the data portion 1022 of (A2 + C1) and the two types of expected values stored in the peripheral storage portion 332 match (S1463). When the authentication is successful, the peripheral board 330 corresponds to the expected value (B2 + C1) because the authentication data is the inspection value (A2 + C1) and matches the expected value (B2 + C1) of the peripheral storage unit 322. The attached data type K2 is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 322 is updated to indicate the data type K2 (S1464). The peripheral board 330 shows the change target pattern P4 with respect to the change target pattern information 1030, as in the case of the main control board 310, 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 (S1465). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P2.

  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 (S1421). 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 (S1422). 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 (S1423), and the authentication information 1020 having the expected value change data. (C2) is generated, and the authentication information 1020 (C2) is transmitted to the peripheral board 330 (S1424). 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 the inspection value (A2 + C2) to the inspection value (A2 + C2) by the above-described change method. Change (S1425).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (C2) from the main control board 310 (S1466), the peripheral side type information in the peripheral side storage unit 322 indicates the expected value change data. With the expected value changing data in the data portion 1022 of 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 changing method (S1467). 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 peripheral board 330 specifies a data type K1 predetermined for generating expected value change data as the next data type, and the peripheral side type of the peripheral side storage unit 322 indicates the data type K1. Information is updated (S1468).

  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 (S1426). 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 (S1427). The main control board 310 generates authentication data for the inspection value (A1 + C2) associated with the data type K1 (S1428). 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 peripheral board 330 (S1429). The main control board 310 indicates the change target pattern P2 with respect to the change target pattern information 1030, 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 (S1430).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A1 + C2) from the main control board 310 (S1469), the peripheral side type information in the peripheral side storage unit 322 indicates the authentication data. The main control board 310 is authenticated by determining whether the authentication data in the data portion 1022 of (A1 + C2) and the two types of expected values stored in the peripheral storage portion 332 match (S1470). When the authentication is established, the peripheral board 330 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 peripheral storage unit 322. The attached data type K1 is identified as the next data type, and the peripheral side type information in the peripheral side storage unit 322 is updated to indicate the data type K1 (S1471). The peripheral board 330 shows the change target pattern P2 with respect to the change target pattern information 1030, as in the case of the main control board 310, and the inspection value (A1 + C2) of the authentication information 1020 for which the authentication has been established. Since the switching method “advance 1” 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 (S1472). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P3. 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. In addition, when the inspection value and the expected value of the authentication information 1020 match the expected value, if the expected value change data of the data type is associated with the expected value, the authentication information received next time is the expected value change Since the expected value can be changed with the expected value change data received from the main control unit and matched with the inspection value of the main control unit 201, the main control unit 201 and The inspection value and the expected value can be changed together with the peripheral portion, and analysis by an unauthorized analyst can be made 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. Further, since the peripheral part can detect that the authentication information has been used illegally by the fraud analyst by the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. 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 also 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 1030 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. .

  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 peripheral portion are randomly selected. Since it can be changed, 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 peripheral unit have predetermined inspections by setting the expected value changing data as a predetermined initial value and a correction value for changing the expected value. Since it is only necessary to change the value and the expected value with the expected value changing data, 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, expected value changing data for preliminarily storing an expected value of a value different from the test value of the main control unit 201 in the peripheral portion and absorbing the difference between the test value and the expected value Is generated by the main control unit 201 and transmitted to the peripheral unit, the expected value is matched with the inspection value of the main control unit by changing the expected value by the peripheral unit using the expected value changing data. 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, as shown in FIG. 20, the pachinko gaming machine 100 has a main control board 310 having a function as the main control unit 201 and functions as peripheral units such as the above-described effect control unit 202 and prize ball control unit 203. And a peripheral substrate 330 having the same. 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 transmission unit 319, an update unit 320, and a selection unit 321 are included.

  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 A using a random number or the like. The selection method of the selection unit 321 preferably has an irregular selection pattern 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 peripheral board 330 includes a receiving unit 331, a peripheral side storage unit 332, an authentication unit 333, a peripheral side switching unit 334, a peripheral side changing unit 335, and a specifying unit 336, as in the first embodiment. ing. Since the peripheral substrate 330 can be realized with the same configuration as that of the first embodiment, the description thereof is omitted.

  In the second embodiment, the CPU 211 of the main control board 310 functions as the first computer in the claims, and the CPUs 241 and 281 of the peripheral board 330 function as the second 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 functioning as various means such as generating means, transmitting means, updating means, and selecting means is stored. In addition, each of the ROMs 242 and 282 of the peripheral board 330 causes the second computer to function as various means such as receiving means, authentication means, peripheral side switching means, peripheral side changing means, and specifying means in the claims. The peripheral authentication program is stored. That is, the authentication program of the present invention is constituted by the main control side authentication program and the peripheral side authentication program.

(Processing for sending and receiving authentication information signals)
Below, the example of communication of the said authentication information signal performed between the main-control part 201 and a peripheral part is demonstrated. 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. 19 and determines in step S1501 whether or not it is a predetermined authentication timing. If the main control unit 201 determines that it is not the authentication timing (S1501: No), the process proceeds to step S1514. On the other hand, if the main control unit 201 determines that it is the authentication timing (S1501: Yes), the process proceeds to step S1502.

  In step S1502, 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 process of step S1503. 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 S1503, 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 (S1503: No), the main control unit 201 proceeds to the process of step S1504. In step S1504, 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 S1505 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> 1505, the main control unit 201 uses the change method described above with the expected value change data stored in the data storage unit 311, among the two types of test values, the test value indicated by the current change target pattern. Then, the process proceeds to step S1506. It should be noted that the test value change timing may be immediately before the test value is selected. In step S1506, 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 processing in step S1512. move on. The predetermined data type is determined in advance between the main control board 310 and the peripheral board 330.

  On the other hand, when the main control unit 201 determines in step S1503 that the data type is authentication data (S1503: Yes), in step S1507, 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 and the like. In step S1508, authentication data having the selected test value is generated and stored in the RAM 213 and the process proceeds to step S1509. As a result, authentication data having one of two types of inspection values is created.

  In step S <b> 1509, 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 by the switching method associated with the selected inspection value, and the changed change target pattern. Is stored in the RAM 213 or the like, and then the process proceeds to step S1510. 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 S1510, 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 processing of step S1511.

  In step S1511, 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 S1512.

  In step S1512, the main control unit 201 encrypts the generated authentication information 1020 with a predetermined encryption method with the peripheral unit, and in step S1513, based on each of the encrypted authentication information 1020. Then, an authentication information signal is generated and transmitted from the transmission unit 319 to the peripheral unit, and then the process proceeds to step S1514. If encryption is not required between the main control unit 201 and the peripheral unit, the processing in step S1512 is deleted, and the authentication information 1020 is transmitted to the peripheral unit as it is. In step S1514, the main control unit 201 updates the type information in the data storage unit 311 to indicate the next data type determined in step S1506 or step S1510, and then proceeds to the process in step S1515.

  In step S1515, 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 (S1515: No), the main control unit 201 returns to the process of step S1501 and repeats a series of processes. On the other hand, when the main control unit 201 determines that the power is turned off (S1515: Yes), the process according to this flowchart ends.

  Subsequently, the authentication information signal reception processing procedure performed by the peripheral CPUs 241 and 281 (second computer) can use the authentication-side processing shown in FIG. To do.

(Example 2 of authentication processing procedure using authentication information)
Next, an example of the authentication processing procedure 2 in the pachinko gaming machine 100 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 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. 22, the main control board 310, which is the person to be authenticated, sets a predetermined data type K1 for this time (S1601). 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 (S1602), and generates authentication data for the inspection value A2 (S1603). 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 (S1604). 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. (S1605). Then, the main control board 310 indicates the change target pattern P1 as an initial setting with respect to the change target pattern information 1030 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 (S1606).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A2) from the main control board 310 (S1651), since the initial peripheral type information indicates the authentication data, the data of the authentication information 1020 (A2) It is determined whether or not the authentication data in the unit 1022 and the two types of expected values stored in the peripheral storage unit 332 match, and the main control board 310 is authenticated (S1652). When the authentication is established, the peripheral substrate 330 matches the expected value B2 of the peripheral storage unit 322 because the authentication data is the inspection value A2, and therefore the data type K2 associated with the expected value B2 Is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 322 is updated to indicate the data type K2 (S1653). The peripheral board 330, like the main control board 310, shows the change target pattern P1 as the initial setting with respect to the change target pattern information 1030, and the inspection value A2 of the authentication information 1020 for which the authentication is 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 (S1654). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P3.

  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 (S1607). 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 (S1608). ), Authentication information 1020 (C1) having the expected value change data C1 is generated, and the authentication information 1020 (C1) is transmitted to the peripheral board 330 (S1609). 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 (S1610). 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 (S1611).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (C1) from the main control board 310 (S1654), the peripheral side type information in the peripheral side storage unit 322 indicates the expected value change data. In the expected value changing data C1 of the data portion 1022 of 1020 (C1), the expected values B1 and B2 defined by the change target pattern P3 shown in FIG. 14 are expected values (B1 + C1) and expected values (B2 + C1) by the above-described changing method. (S1656). 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 peripheral board 330 specifies a data type K1 predetermined for generating expected value change data as the next data type, and the peripheral side type of the peripheral side storage unit 322 indicates the data type K1. Information is updated (S1657).

  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 (S1612). 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 (S1613), and generates authentication data for the inspection value A1 + C1 (S1614). The main control board 310 generates authentication information 1020 (A1 + C1) having the authentication data, and transmits the authentication information 1020 (A1 + C1) to the peripheral board 330 (S1615). Then, the main control unit 310 determines 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 (S1616). The main control board 310 indicates the change target pattern 3 with respect to the change target pattern information 1030, 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 (S1617).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A1 + C1) from the main control board 310 (S1658), the peripheral side type information in the peripheral side storage unit 322 indicates the authentication data. The main control board 310 is authenticated by determining whether the authentication data in the data portion 1022 (A1 + C1) and the two types of expected values stored in the peripheral storage portion 332 match (S1659). When the authentication is successful, the peripheral board 330 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 peripheral storage unit 322. The attached data type K1 is identified as the next data type, and the peripheral side type information in the peripheral side storage unit 322 is updated to indicate the data type K1 (S1660). The peripheral board 330 shows the change target pattern P3 with respect to the change target pattern information 1030, as in the case of the main control board 310, and the inspection value (A1 + C1) of the authentication information 1020 for 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 (S1661). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P4.

  Subsequently, in FIG. 23, 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 (S1618). 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 (S1619), and generates authentication data for the inspection value A2 + C1 (S1620). The main control board 310 generates authentication information 1020 (A2 + C1) having the authentication data, and transmits the authentication information 1020 (A2 + C1) to the peripheral board 330 (S1621). 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 (S1622). The main control board 310 shows the change target pattern P4 with respect to the change target pattern information 1030, 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 (S1623).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A2 + C1) from the main control board 310 (S1662), the peripheral side type information in the peripheral side storage unit 322 indicates the authentication data. The main control board 310 is authenticated by determining whether or not the authentication data in the data portion 1022 of (A2 + C1) matches the two types of expected values stored in the peripheral storage portion 332 (S1663). When the authentication is successful, the peripheral board 330 corresponds to the expected value (B2 + C1) because the authentication data is the inspection value (A2 + C1) and matches the expected value (B2 + C1) of the peripheral storage unit 322. The attached data type K2 is specified as the next data type, and the peripheral side type information in the peripheral side storage unit 322 is updated to indicate this data type K2 (S1664). The peripheral board 330 shows the change target pattern P4 with respect to the change target pattern information 1030, as in the case of the main control board 310, 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 (S1665). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P2.

  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 (S1624). Since the type information indicates the data type K2, 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 (S1625). Then, the main control board 310 generates authentication information 1020 (C2) having the expected value change data C2, and transmits the authentication information 1020 (C2) to the peripheral board 330 (S1626). 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 (S1627). 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. (S1628).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (C2) from the main control board 310 (S1666), the peripheral side type information in the peripheral side storage unit 322 indicates the expected value change data. In the expected value changing data C2 of the data portion 1022 of 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 changing method (S1667). 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 peripheral board 330 specifies a data type K1 predetermined for generating expected value change data as the next data type, and the peripheral side type of the peripheral side storage unit 322 indicates the data type K1. Information is updated (S1668).

  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 (S1629). 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 (S1630), and generates authentication data for the inspection value A1 + C2 (S1631). 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 peripheral board 330 (S1632). 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 (S1633). The main control board 310 indicates the change target pattern P2 with respect to the change target pattern information 1030, 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 (S1634).

  On the other hand, when the peripheral board 330 receives the authentication information 1020 (A1 + C2) from the main control board 310 (S1669), the peripheral side type information in the peripheral side storage unit 322 indicates the authentication data. The main control board 310 is authenticated by determining whether or not the authentication data in the data portion 1022 (A1 + C2) and the two types of expected values stored in the peripheral storage portion 332 match (S1670). When the authentication is established, the peripheral board 330 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 peripheral storage unit 322. The attached data type K1 is identified as the next data type, and the peripheral side type information of the peripheral side storage unit 322 is updated to indicate the data type K1 (S1671). The peripheral board 330 shows the change target pattern P2 with respect to the change target pattern information 1030, as in the case of the main control board 310, and the inspection value (A1 + C2) of the authentication information 1020 for 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 (S1672). As a result, both the main control board 310 and the peripheral board 330 are switched to the change target pattern P3. 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. In addition, when the inspection value and the expected value of the authentication information 1020 match the expected value, if the expected value change data of the data type is associated with the expected value, the authentication information received next time is the expected value change Since the expected value can be changed with the expected value change data received from the main control unit and matched with the inspection value of the main control unit 201, the main control unit 201 and The inspection value and the expected value can be changed together with the peripheral portion, and analysis by an unauthorized analyst can be made 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. Further, since the peripheral part can detect that the authentication information has been used illegally by the fraud analyst by the data type of the authentication information 1020, the authentication strength of the authentication information 1020 can be increased. 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 also 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 1030 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.

  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 peripheral portion are randomly selected. Since it can be changed, 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 change data is a predetermined initial value and a correction value for changing the expected value, so that the main control 201 unit and the peripheral unit have a predetermined test value. Since it is only necessary to change the value and the expected value with the expected value changing data, 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, expected value changing data for preliminarily storing an expected value of a value different from the test value of the main control unit 201 in the peripheral portion and absorbing the difference between the test value and the expected value Is generated by the main control unit 201 and transmitted to the peripheral unit, the expected value is matched with the inspection value of the main control unit by changing the expected value by the peripheral unit using the expected value changing data. Therefore, it is possible to make it difficult to analyze and use the inspection value and the expected value by an unauthorized analyst.
